Description

Horizontal filter press

Technical Field

The invention relates to the field of filter press devices, in particular to a horizontal filter press.

Background

The filter press is a common solid-liquid separation device, and is often used for realizing solid-liquid separation in the fields of chemical industry, metallurgy, medicine, food and the like, and meanwhile, the filter press can also be used for sludge dewatering in a wastewater treatment process in environmental protection industrial engineering such as medicine, chemical industry, pharmacy, metallurgy, fuel, food, brewing, ceramics, oil refining, sewage treatment and the like, and is ideal equipment for environmental control and resource recovery. At present, a plate-and-frame filter press is widely used, wherein a group of filter chambers are formed by alternately arranged filter plates and filter frames, solid-liquid materials are generally extruded by the pressure of a feed inlet to achieve solid-liquid separation after a solid-liquid mixture enters the filter chambers, but the water content of the materials after filter pressing is still about 70 percent due to the small self pressure, and the deep dehydration of the materials cannot be realized.

The invention aims to provide a horizontal filter press which has better filter pressing effect.

In order to achieve the above purpose, the basic scheme of the invention is as follows: a horizontal filter press comprising: the pressing mechanism comprises a hydraulic cylinder body, an oil pipe, a piston rod and an oil tank filled with hydraulic oil, wherein a piston is connected in the hydraulic cylinder body in a sliding manner, two ends of the oil pipe are respectively communicated with the oil tank and the hydraulic cylinder body, and the oil pipe is provided with a hydraulic pump; one end of the piston rod is fixedly connected with the piston, the other end of the piston rod extends out of the hydraulic cylinder body and is connected with an extrusion plate, and the extrusion plate is connected with the slide rail in a sliding manner;

the mud fixing part comprises a ring body, an annular part and a plurality of connecting plates, the diameter of the annular part can be changed, and the maximum diameter of the annular part is the same as that of the ring body; the two ends of the connecting plate are respectively hinged with the ring body and the annular part, and the sieve plate is fixed at one end of the base, which is far away from the hydraulic cylinder body, and is abutted against the annular part; the lower end of the sieve plate is provided with a water collecting part.

The working principle and the beneficial effects of the basic scheme are as follows: when needing the filter-pressing, will treat that the mud of filter-pressing is placed in solid mud portion, then start the hydraulic pump, the hydraulic pump rotates and passes through the oil pipe with the hydraulic oil in the oil tank and pump into hydraulic cylinder body. Under the hydraulic action of the hydraulic oil, the piston moves towards the direction of the mud fixing part and drives the piston rod to move towards the direction of the mud fixing part. Because piston rod one end and stripper plate fixed connection, so the piston rod can drive the stripper plate and remove to solid mud portion direction, extrudees the mud in the solid mud portion, makes mud receive axial power, extrudes the liquid in the mud, and the liquid that is extruded flows through the sieve board during, realizes the filter-pressing to mud. Because the solid mud part includes the ring body, a plurality of connecting plates and annular portion, promptly solid mud part is cylindric in the initial condition. And the diameter of annular portion can change, so when the filter-pressing, can lap the diameter of annular portion, become the diameter of annular portion soon and diminish, solid mud portion becomes the round platform form by cylindric, makes mud receive radial pressure when receiving axial pressure, is convenient for extrude the water in the mud more, makes the filter-pressing effect better.

The piston moves along the hydraulic cylinder as the hydraulic pump pumps hydraulic oil into the hydraulic cylinder. At this time, the hydraulic oil does not enter the communicating pipe. Along with the continuation slip of piston, the piston removes behind the junction of communicating pipe and hydraulic cylinder body, continue to slide, the part that is filled with hydraulic oil in communicating pipe and the hydraulic cylinder body this moment, hydraulic oil enters into communicating pipe and enters into first connecting pipe through communicating pipe, because first connecting pipe is equipped with the cavity, the second connecting pipe passes through cavity and the sealed sliding connection of first connecting pipe, so under the hydraulic action of the hydraulic oil in first cavity, the second connecting pipe slides to the direction of keeping away from first connecting pipe, flexible pipe extension promptly, make the annular portion diameter diminish, the diameter that realizes the annular portion automatically when the extrusion through the stripper plate diminishes like this, only realize automatically through a hydraulic pump promptly to mud axial and radial extrusion, and the operation is convenient, and the effect is better.

The preferable scheme is four: as a preferred scheme of the third preferred scheme, an elastic layer is arranged between the connecting plates, and the elastic layer is arranged to prevent sludge from leaking out of gaps between adjacent connecting plates to influence the filter pressing effect.

The preferable scheme is five: as a preferable mode of the basic mode or the third preferable mode, a first elastic member is provided between the end of the hydraulic cylinder and the piston, and a second elastic member is provided between the first connecting pipe and the second connecting pipe. After the filter-pressing is completed, the hydraulic pump is reversely rotated, the piston automatically returns to the initial position under the action of the first elastic piece, the first connecting pipe and the second connecting pipe return to the initial position under the action of the second elastic piece, the solid mud part becomes cylindrical again, and the sludge after the filter-pressing can be taken out conveniently.
