[0029] The following further describes the present utility model in conjunction with the accompanying drawings. The protection scope of the present utility model is not limited to the following:

[0030] As Figures 5 to 11 shown, a water collecting filter plate of a filter press includes a filter plate body 1. Sealing ring installation components B9 are provided at the four corners of the filter plate body 1. The sealing ring installation component B9 at the topmost part includes a connecting seat 3 fixed on the filter plate body 1. A liquid passing through hole 4 is opened in the connecting seat 3. A transfer joint 10 is fixed in the liquid passing through hole 4. The transfer joint 10 is welded in the liquid passing through hole 4. Threaded columns 11 are fixed on the two outer end faces of the transfer joint 10. Collars 12 are threadedly connected to the two threaded columns 11. The inner end part of the collar 12 abuts against the threaded column 11. The outer end part of the collar 12 extends outside the liquid passing through hole 4, and a retaining ring 6 is fixed on the outer cylindrical surface of the extending end. The retaining ring 6 is welded on the collar 12.

[0031] Annular grooves 7 are opened on the two outer end faces of the connecting seat 3. The annular grooves 7 are located outside the collar 12 and are provided directly below the retaining ring 6. Sealing rings 8 are embedded in the annular grooves 7. Among them, the function of the retaining ring 6 is to prevent the sealing ring 8 from coming out of the annular groove 7.

[0032] The outer diameter of the collar 12 is equal to the diameter of the liquid passing through hole 4. Threaded holes 13 are opened on the inner end face of the collar 12. The collar 12 is threadedly connected to the threaded column 11 through the threaded hole 13 to be fixed on the transfer joint 10. The retaining ring 6, the collar 12, the annular groove 7 and the liquid passing through hole 4 are coaxially arranged.

[0033] The working process of the present utility model is as follows:

[0034] When two water collecting filter plates squeeze the material between them, the retaining ring 6 of the left water collecting filter plate will collide with the right water collecting filter plate. After the two retaining rings 6 collide for a long time, the retaining ring 6 will be deformed, causing the deformed retaining ring 6 to damage the sealing ring 8.

[0035] When the worker finds that the retaining ring 6 on the water collecting filter plate is damaged, the specific operation method for the worker to replace the retaining ring 6 is as follows:

[0036] S1. The worker first rotates the corresponding damaged retaining ring 6. The retaining ring 6 drives the sleeve ring 12 welded to it to rotate. The threaded hole 13 of the sleeve ring 12 rotates relative to the threaded post 11 of the adapter 10. When the threaded hole 13 of the sleeve ring 12 disengages from the threaded post 11, the worker pulls the sleeve ring 12 in the direction away from the liquid passing through hole 4, thereby pulling out the sleeve ring 12 and the damaged retaining ring 6;

[0037] S2. After pulling out, the worker takes out a new sleeve ring with a retaining ring again. The worker inserts the new sleeve ring into the liquid passing through hole 4, and then rotates the sleeve ring movably to connect the threaded hole in the sleeve ring with the threaded post 11 of the adapter 10, thereby finally realizing the replacement of the damaged retaining ring.

[0038] Among them, it can be seen from steps S1 to S2 that when the retaining ring 6 is damaged by long-term impact, the worker only needs to pull out the damaged retaining ring 6 first, and then replace it with a new retaining ring 6, so that the entire water collecting filter plate can continue to be used. Therefore, compared with the water collecting filter plate Figures 1 to 3 as shown, it is not necessary for the worker to replace the entire water collecting filter plate, thus saving the cost of purchasing a new water collecting filter plate, and further greatly saving the operation cost.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
