Technical field:

The present invention relates to Powder Recovery machine technology field, the Powder Recovery machine of using more specifically to a kind of industrial coating production line.

Background technology:

Shanghai is newly measured electrostatic spraying factory and has been researched and developed a kind of rotor formula filter core powder recovering device, and it adopts secondary recovery.Many cyclone recovery systems of powdery paints electrostatic spraying have been introduced by Hefei Rongshida Sanyo Electric Co., Ltd., static research institute of Guangzhou Cigna has researched and developed powder spraying complete set of equipments, polynary whirly reclaims unit, and Linqu, the Shandong prosperous electrostatic spraying device of gold Co., Ltd has developed pulse backblowing rotor sieve core callback device, golden prosperous whirlwind retracting device.All there is following problem in the equipment of above company: 1, recycling amount is lower, and organic efficiency is relatively poor.2, filter core easily produces the bonding phenomenon, the retardance airflow, and the cleaning of filter core is convenient inadequately with maintenance, and filter element life is short simultaneously.3, be to utilize the clear dirt of blowback under the positive pressure at the recover inner chamber, dust removing effects is undesirable, and the laying dust phenomenon is serious.

Summary of the invention:

Purpose of the present invention is exactly the deficiency at prior art, and provides a kind of industrial coating production line automatic Powder Recovery machine, has improved 50% on its treating capacity, and organic efficiency has really realized the continuous auto recycling of powder up to more than 98%; The not sticking powder of filter core, blowback is thorough; Filter cloth is sturdy and durable to be 6-8 times that general paper is filtered the life-span.

Technology solution of the present invention is as follows:

The automatic Powder Recovery machine of industrial coating production line, the collection powder car, powder delivery pump pump that comprise the room that dusts, workpiece, powder delivery pump are housed for the powder in the powder chamber to spray gun, workpiece places the room that dusts, spray gun is facing to workpiece, the main meal outlet that the air inlet of multicyclone connects the room that dusts, multicyclone connects for the powder chamber, and the air outlet of multicyclone connects the superfine powder filter chamber of back level pulse recover;

Back level pulse recover is made up of body, blower fan, filter cotton, impulse electromagnetic valve, gas storage bag, filter core, superfine powder powder collector, body top pure air floss hole is coated with filter cotton, blower fan is loaded on the upper chambers of body, the middle part of body is the pulse backblowing chamber, gas storage bag and impulse electromagnetic valve are arranged in engine body exterior, the gas storage bag connects the pulse backblowing chamber, connects at the gas storage bag on the pipeline of pulse backblowing chamber impulse electromagnetic valve is installed;

Underpart is the superfine powder filter chamber, and superfine powder is fixed with filter core in the filter chamber, and the bottom of body is placed with superfine powder collection powder case.

Described filter core is vertical layout, and the superfine powder of multicyclone is side direction and blows to filter core.

Described multicyclone is by sub-air chamber, flow deflector, whirlwind, insert pipe, the steady air current chamber is formed, insert the pipe bottom and connect whirlwind, insert the superfine powder meal outlet of pipe top towards the cyclone separator of shell separator formation, dust and be fixed with draft hood in the room, draft hood connects sub-air chamber, be fixed with flow deflector in the sub-air chamber, the air inlet of whirlwind connects sub-air chamber, the outlet of whirlwind connects the steady air current chamber, the bottom of steady air current chamber is equipped with vibratory sieve, vibratory sieve is installed in the shell separator, and the shell separator lower pipeline connects the confession powder chamber of the collection powder car that powder delivery pump is housed.

Beneficial effect of the present invention is:

1, equipment reclaims with former action of low-voltage pulse back flushing type and compares, and under the same consumption energy situation, has improved 50% on treating capacity, and organic efficiency has really realized the continuous auto recycling of powder up to more than 98%.

2, adopt the outer TEFLON coating technology of filter core.Working surface is coated filming of TEFLON material in filter core, and coating is not blocked the fiber pore attached to filter core fibrous material surface, makes fiber surface have not viscosity, does not produce the bonding phenomenon, the retardance airflow.And adopt intelligent filter core to clear up monitoring system automatically.

3, the automatic rotor formula cleaning of filter core system, the technical matters of rotor formula structure unites two into one the Powder Recovery of equipment, dedusting function, improves organic efficiency.Start the automatic rotor formula cleaning of filter core system, close corresponding filter core air quantity wind path simultaneously, prevent that the secondary powder gathers again on the filter core air quantity wind path, help the cleaning effect of filter core, reach and fall the energy environmental protection.

4, filter material adopts 100% tough and tensile durable polyester fiber, is coated with not siliceous extraordinary glue-line on the surface, and extraordinary glue-line is to not absorption mutually of dust; Carry out the high-rate laser punching at the special gelatin laminar surface, the aperture is slightly less than the recovery dust size, and hole count adopts the dot matrix design, reaches maximization; Special gelatin metafiltration paper adopts accordion structure, the surface area maximization.Good permeability is not easy bonding, and powder water easily sinks to reclaiming.

5, optimize the design of side direction exhausting, filter core is vertically installed.According to the wind path characteristic, filter core intersection dot matrix is arranged, impels air-flow evenly freely to pass through around the filter core, makes each filter core reach best landscape.
