Background technology
The electrolyte block that the anode anode scrap returned by cell room during Aluminum Electrolysis Production is cleared up and the electrolysis material block from the pallet that depot is tumbled need to return electrolysis bath after being crushed to certain particle size and are continuing with.
The broken main employing jaw crusher of electrolyte adds impact breaker or double-roll crusher carries out two-stage crushing for a long time, the solution that electrolyte crushing system exists that crushing efficiency is low, equipment failure rate is high, plant maintenance and maintenance workload is big, labor intensity is high problem can not get always, at present, the trial of some producers carries out two-stage crushing by configuring autogenous tumbling mill replacement impact breaker, yield is greatly improved, but the raw meal particle size that autogenous tumbling mill is discharged is meticulous, it is nearly all powder, is unfavorable for electrolysis production needs.
Summary of the invention
It is an object of the invention to: for the defect of prior art, a kind of drum-type screening crusher and method for designing thereof are provided, it utilizes the material that is broken from as medium, realize broken by mutual impact and ablation, its sieve plate constantly rotates simultaneously, the broken material meeting size after realizing being broken can flow out quickly through sieve plate, prevents from being destroyed by secondary causing granularity meticulous, to overcome the deficiencies in the prior art.
Technical scheme
A kind of method for designing of drum-type screening crusher, disintegrating machine will be broken material lifting to certain altitude, mutually impact and the ablation fallen by material realize broken, after Po Sui, the material less than sieve plate hole falls into drum-type screening crusher bottom aggregate bin through sieve plate hole, and discharged continuously by conveying equipment, thus realize broken to the material that is broken and sieve the function simultaneously carried out.
In the method for designing of aforesaid a kind of drum-type screening crusher, being surrounded by sieve plate in the middle part of the rotation cylinder of described disintegrating machine, sieve plate support is as support, and disintegrating machine uses support roller support and make it rotate by chain drive mode.
In the method for designing of aforesaid a kind of drum-type screening crusher, the structure of the material lifting that is broken uses to be evenly arranged in disintegrating machine and carries flitch.
A kind of drum-type screening crusher, cylinder is rotated including disintegrating machine, disintegrating machine rotate cylinder rear and front end be respectively provided with one group of support roller realize this disintegrating machine rotate cylinder free to rotate, wherein the mid-section body of disintegrating machine rotation cylinder is surrounded by sieve plate, carry flitch and disintegrating machine and rotate that centre of the drum's line is parallel and uniform to be distributed on sieve plate inner surface, rotating cylinder at disintegrating machine and be arranged right below aggregate bin, support roller, aggregate bin are fixed on base and realize the fixing of disintegrating machine rotation cylinder.
In aforesaid a kind of drum-type screening crusher, rotate cylinder side at disintegrating machine and be provided with gear bar, drive motor to use chain connected mode to coordinate the driving realizing that disintegrating machine rotates cylinder with gear bar.
In aforesaid a kind of drum-type screening crusher, it is provided with sieve plate support intersected with each other at sieve plate outer surface.
In aforesaid a kind of drum-type screening crusher, it is provided with triangular shape gripper shoe carrying flitch non-working surface.
In aforesaid a kind of drum-type screening crusher, described aggregate bin top is class semicircular structure.
In aforesaid a kind of drum-type screening crusher, dust cover is arranged on disintegrating machine and rotates directly over cylinder and can be connected with both sides, aggregate bin top.
nullOwing to have employed technique scheme，Compared with prior art，The present invention is a kind of has the broken and novel grinding attachment of two kinds of functions of screening concurrently，It utilizes the material that is broken from as medium，Realize broken by mutual impact and ablation，Be provided with band crushing function in drum-type screening crusher cracking cabin carries flitch，Under the rated speed of design，Material lifting will be broken to certain altitude，Mutually impact and the ablation fallen by material realize broken，The special flitch that carries set in Tong Shi also functions to strengthen broken effect further，After Po Sui, the material less than sieve plate hole falls into drum-type screening crusher bottom aggregate bin (owing to sieve plate rotates always through sieve plate hole，Realize quick sub-sieve and reach the material of broken size，Effectively prevent the second-time breakage of broken material)，And discharged continuously by conveying equipment，The broken ratio of the present invention is big、Production capacity is high、Energy consumption is low、Simple in construction、Product granularity degree of protection is high，Use support roller supported design strong compared with dynamic and hydrostatic bearing supporting way environmental suitability、Reduced investment、Maintenance difficulty is little，It is strong that cylinder uses chain drive mode to have environmental suitability equally compared with meshed transmission gear mode、Reduced investment、The advantages such as maintenance difficulty is little.Metal contained in material and the most breakable foreign material, can discharge from disintegrating machine tail end by the way of periodically emptying material, will not produce downstream and equipment impacts.
Sieve plate hole is specially designed, can effectively reduce the generation of feed blocking situation, and sieve plate, carrying flitch, all to use high-abrasive material to manufacture the life-span long, and complete machine is provided with the seal closure of band maintenance door, and dust control and noise absorption is effective.
Detailed description of the invention
Below in conjunction with the accompanying drawings to the present invention with being described in further detail, but not as any limitation of the invention.
Embodiments of the invention: the method for designing of a kind of drum-type screening crusher, disintegrating machine will be broken material lifting to certain altitude, mutually impact and the ablation fallen by material realize broken, after Po Sui, the material less than sieve plate hole falls into drum-type screening crusher bottom aggregate bin through sieve plate hole, and discharged continuously by conveying equipment, thus realize broken to the material that is broken and sieve the function simultaneously carried out.
Wherein being surrounded by sieve plate in the middle part of the rotation cylinder of this disintegrating machine, sieve plate support is as support, and disintegrating machine uses support roller support and make it rotate by chain drive mode, and the structure of the material lifting that is broken uses to be evenly arranged in disintegrating machine and carries flitch.
nullAccording to a kind of drum-type screening crusher constructed by said method，As shown in drawings，Cylinder 1 is rotated including disintegrating machine，Disintegrating machine rotate cylinder 1 rear and front end be respectively provided with one group of support roller 2 realize this disintegrating machine rotate cylinder 1 free to rotate，Rotate cylinder 1 side at disintegrating machine and be provided with gear bar 7，Motor 8 is driven to use chain 9 connected mode to coordinate the driving realizing that disintegrating machine rotates cylinder 1 with gear bar 7，Wherein the mid-section body of disintegrating machine rotation cylinder 1 is surrounded by sieve plate 3，Carry flitch 4 and disintegrating machine rotate cylinder 1 centerline parallel and uniform be distributed on sieve plate 3 inner surface，It is provided with triangular shape gripper shoe 11 carrying flitch 4 non-working surface，It is provided with sieve plate support 10 intersected with each other at sieve plate 3 outer surface，Rotate cylinder 1 at disintegrating machine and be arranged right below aggregate bin 5，This aggregate bin 5 top is class semicircular structure，Support roller 2、Aggregate bin 5 is fixed on base 6 and realizes the fixing of disintegrating machine rotation cylinder 1，Dust cover 12 is arranged on disintegrating machine and rotates directly over cylinder 1 and can be connected with both sides, aggregate bin 5 top.
