Description

Technical Field

[0001] The invention relates to the field of filter press cloth clamps, and in particular to a filter press filter cloth locking device. Background Art

[0002] The filter cloth is the filter medium installed on the filter plate of the filter press. During filtration, the material enters the filter chamber and the particles in the material are intercepted by the filter cloth to form a filter cake, and the filtrate is discharged to achieve the filtering purpose of solid-liquid separation. The central feed hole of the filter press is set at the center of the filter plate. In the process of solid-liquid separation of iron concentrate slurry by the center-fed filter press, the filter cloth and ordinary cloth clamps are easily worn by the iron concentrate slurry when feeding the filter press, so that the filter cloth and the cloth clamps are damaged, causing the iron concentrate slurry to leak at the central feed hole, resulting in the material not meeting the requirements and affecting the quality of the product. At the same time, in the process of blowing and drying the filter cake of the filter press, the high-speed and high-pressure environment will cause the iron concentrate particles to pass through the leakage position quickly, which will cause the filter cloth, filter plate and cloth clamp of the filter press to wear quickly until they are damaged, thereby affecting the quality of the iron concentrate product and the entire production process of the filter press. Summary of the invention

[0003] In order to solve the above-mentioned deficiencies, the purpose of the present invention is to provide a filter cloth locking device for a filter press, wherein the integrated feed sleeve of the locking device is vertically passed through the center hole of the filter cloth, the center feed hole of the filter plate and the center hole of the filter cloth on the other side until the external thread at the pipe mouth of the integrated feed sleeve is exposed, and then the locking flange is installed, and the locking flange is tightened to clamp the filter cloth, so that the filter cloth is not easily worn and the material will not leak.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] A filter cloth locking device for a filter press comprises an integrated feed sleeve and a locking flange, wherein the integrated feed sleeve comprises a central sleeve and a flange, one end of the central sleeve is fixed with a flange, the other end is provided with an external thread, the locking flange is provided with an internal thread, and the locking flange and the central sleeve are used in cooperation through the internal and external threads;

[0006] The filter cloth of the filter press is laid flat on both sides of the filter plate of the filter press. The flange and the locking flange are respectively placed on both sides of the filter plate of the filter press and can clamp the filter cloth. The central sleeve vertically passes through the filter plate of the filter press.

[0007] Furthermore, the flange, the center sleeve and the locking flange are all hollow structures.

[0008] Furthermore, the flange and the locking flange are circular structures, and the central sleeve is a cylindrical structure.

[0009] Furthermore, the filter cloth of the filter press is provided with a central hole of the filter cloth having the same size as the central feed hole of the filter plate.

[0010] Furthermore, the inner wall diameter of the flange is larger than the outer wall diameter of the central sleeve.

[0011] Furthermore, at least one sealing ring is provided on the external thread of the central sleeve.

[0012] Furthermore, the outer wall diameter of the locking flange is the same as the outer wall diameter of the flange.

[0013] Furthermore, the integrated feed sleeve and locking flange are cast in one go using stainless steel through a mold.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention solves the problem of slurry leakage from the filter cloth at the central feed hole.

[0016] 2. The present invention solves the problem of frequent damage of the filter cloth and increases the service life of the filter cloth.
