[0030] See Figure 1 、 Figure 2 、 Figure 3 And Figure 4 , the present utility model provides a filter press for sewage treatment, including:

[0031] Sewage treatment tank 1 and treatment components, where:

[0032] A support rod 6 is fixedly arranged on the inner wall of the bottom of the sewage treatment tank 1. The top end of the support rod 6 is fixedly provided with a filter disc 7. A filter cylinder 5 is in contact with the top end of the filter disc 7. A sewage inlet pipe 8 is fixedly arranged on the top of the sewage treatment tank 1. The bottom end of the sewage inlet pipe 8 is fixedly provided with a flexible hose 9. The bottom end of the flexible hose 9 is fixedly provided with a connecting pipe 10. The connecting pipe 10 is fixedly installed on the filter cylinder 5. It should be noted that sewage is added through the sewage inlet pipe 8, and is added into the filter cylinder 5 through the flexible hose 9 and the connecting pipe 10. Then, the filter cylinder 5 and the filter disc 7 perform filtration treatment on the sewage. The filtered sewage is discharged through the drain pipe 16. The filter residue in the filter cylinder 5 is processed by the processing component; the processing component is arranged on the sewage treatment tank 1 and the filter cylinder 5.

[0033] Specifically, the processing component includes a power motor 2, a power shaft 3, a connecting rod 4, a hydraulic cylinder 11 and a pressing plate 12. The power motor 2 is fixedly installed on the inner wall of the bottom of the sewage treatment tank 1. The output end of the power motor 2 is fixedly connected to the power shaft 3. The connecting rod 4 is fixedly installed between the power shaft 3 and the filter cylinder 5. The hydraulic cylinder 11 is fixedly installed on the top end of the filter cylinder 5. The hydraulic rod of the hydraulic cylinder 11 is fixedly connected to the pressing plate 12.

[0034] With the above structure, when it is necessary to process the impurities in the filter cylinder 5, start the hydraulic cylinder 11. The hydraulic cylinder 11 drives the pressing plate 12 to move downward. The pressing plate 12 can extrude the filter residue in the filter cylinder 5 to squeeze out the remaining water in the filter residue. Then start the power motor 2. The power motor 2 drives the power shaft 3 to rotate. The power shaft 3 drives the connecting rod 4 to rotate. The connecting rod 4 drives the filter cylinder 5 to rotate, so that the filter cylinder 5 is moved away from the filter disc 7. Then continue to start the hydraulic cylinder 11, so that the pressing plate 12 continues to move downward to push out the filter residue in the filter cylinder 5. In this way, it is convenient to automatically clean the filter residue, and it is relatively convenient to use.

[0035] It should also be noted that a collection box can be placed in the sewage treatment tank 1 to collect the ejected filter residue.

[0036] Specifically, a protective cover 13 is fixedly arranged on the inner wall of the bottom of the sewage treatment tank 1. The top of the protective cover 13 is fixedly provided with a support plate 14. The side of the support plate 14 is fixedly provided with a top plate 15. Sealing bearings are fixedly arranged on both the protective cover 13 and the top plate 15. The power shaft 3 is fixedly connected to the inner ring of the sealing bearing. It should be noted that the stability of the power shaft 3 during rotation is improved.

[0037] Specifically, a drain pipe 16 is fixedly arranged on the side of the sewage treatment tank 1. It should be noted that it is convenient to discharge the filtered sewage in the sewage treatment tank 1.

[0038] Specifically, a sealing gasket is fixedly arranged at the bottom end of the filter cylinder 5. The sealing gasket is in sealed contact with the filter disc 7. It should be noted that the sealing performance at the connection between the filter cylinder 5 and the filter disc 7 can be ensured.

[0039] Specifically, the pressing plate 12 is slidably installed inside the filter cartridge 5, and the connecting pipe 10 is of an L-shaped structure. It should be noted that the shape of the connecting pipe 10 is defined.

[0040] The above has introduced in detail a filter press provided by the present utility model. Specific embodiments are used herein to illustrate the principle and implementation manner of the present utility model. The description of the above embodiments is only for helping to understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
