Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a plate and frame filter press for wastewater treatment. Background Technology

[0002] A filter press is a pressure-driven solid-liquid separation device, mainly used to separate solids and liquids in suspension. Its working principle is that the material is sent into the space between the filter plates by a pump. Under high pressure, the liquid passes through the filter cloth and is discharged as filtrate, while the solids are trapped in the filter chamber to form a filter cake, thereby achieving solid-liquid separation. This equipment has the characteristics of high separation efficiency, high solid content in the filter cake, and wide applicability. It is widely used in filtration, dewatering, and purification processes in industries such as chemical, mining, sewage treatment, food, and pharmaceutical.

[0003] Upon investigation, a utility model patent disclosed a plate and frame filter press (publication number: CN220834298U), which includes a support frame.

Multiple filter plates are arranged on the top of the support frame. A cylinder is installed on one side of the mounting bracket, and a pressing plate is fixedly connected to the output end of the cylinder. The pressing plate is adapted to the multiple filter plates. An extension plate is fixedly connected to one end of the support frame, and a connecting block is fixedly connected to one end of each of the multiple filter plates. The top of the extension plate is constructed with a separation component that drives the multiple connecting blocks to move relative to each other.

[0004] In the aforementioned patent, the first slider is pushed by the elastic force of the return spring, which can cause the first slider and the second slider to move away from each other, thereby causing the scissor telescopic frame to extend, and thus enabling multiple filter plates to move away from each other, improving the discharge efficiency of the sludge cake. However, the sewage pipe and the connecting pipe are connected by a flange. This connection method requires the use of multiple sets of bolts and nuts for fixing. When installing the sewage pipe, the assembly of bolts and nuts is cumbersome and takes a lot of time, reducing work efficiency.

[0005] Therefore, this utility model provides a plate and frame filter press for sewage treatment to solve the above problems. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a plate and frame filter press for wastewater treatment, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the filter press body 1 is included. A sewage pipe 2 is provided on one side of the filter press body 1. A cylinder 3 is fixedly connected to one end of the sewage pipe 2. A connecting cylinder 4 is fixedly connected to one side of the filter press body 1. A fixing component is provided on the connecting cylinder 4.

[0020] The fixing assembly includes a fixing shell 5, one side of which is fixedly connected to the side surface of the connecting cylinder 4. A connecting rod 6 is movably connected inside the fixing shell 5. One end of the connecting rod 6 is fixedly connected to a pin 7. The side surface of the pin 7 slides against the inner wall of the fixing shell 5. The other end of the connecting rod 6 extends to the outside of the fixing shell 5 and is rotatably connected to an adjusting handle 9. A first spring 8 is sleeved on the side surface of the connecting rod 6.

[0021] The connecting cylinder 4 has a through hole 10. The inner cavity of the fixing shell 5 is connected to the inner cavity of the connecting cylinder 4 through the through hole 10. The side surface of the insert cylinder 3 has an insertion hole 11 that is compatible with the insertion post 7. The side surface of the insertion post 7 slides against the inner wall of the through hole 10. The insert cylinder 3 is inserted into the inside of the connecting cylinder 4, and the insertion post 7 is inserted into the inside of the insertion hole 11.

[0022] The adjusting handle 9 can rotate 90 degrees. When the adjusting handle 9 rotates, it can pull the insert 7 through the connecting rod 6. When the sewage pipe 2 is connected to the filter press body 1, the insert 3 needs to be inserted into the inside of the connecting tube 4. When the insertion hole 11 is aligned with the insert 7, the operator can turn the adjusting handle 9 so that the connecting rod 6 drives the insert 7 to be inserted into the inside of the insertion hole 11, thereby restricting the insert 3 and realizing the connection and fixation of the sewage pipe 2.

[0023] Furthermore, in order to improve the stability of the adjusting handle 9, such as Figure 2 , Figure 3 and Figure 5 As shown, one end of the first spring 8 is fixedly connected to the inner wall of one side of the fixed shell 5, and the other end of the first spring 8 is fixedly connected to the side of the insert 7 near the connecting rod 6. One side of the adjusting handle 9 is in contact with the side of the fixed shell 5 away from the connecting cylinder 4.

[0024] The first spring 8, through the insert 7 and the fixed shell 5, can always apply force to the adjusting handle 9, thereby making the adjusting handle 9 fit tightly against the fixed shell 5, effectively improving the stability of the adjusting handle 9.

[0025] Furthermore, to facilitate the staff in securing the insert 3, such as... Figure 1 , Figure 2 and Figure 5 As shown, the connecting cylinder 4 has a guide groove 13 that communicates with its inner cavity, and the side surface of the insert cylinder 3 is fixedly connected to a guide block 12, which is inserted into the inside of the guide groove 13.

[0026] The guide block 12 and guide groove 13 provide guidance for the staff. When connecting the insert 3 to the connecting tube 4, the guide block 12 needs to be aligned with the guide groove 13. When the insert 3 is inserted into the inside of the connecting tube 4, the guide block 12 will also move inside the guide groove 13. When the guide block 12 moves to the end of the guide groove 13, the insertion hole 11 is just aligned with the insertion post 7, which makes it easier for the staff to fix the insert 3.

[0027] In order to allow the insertion post 7 to smoothly enter the insertion hole 11, such as... Figure 2 , Figure 4 and Figure 6 As shown, a slide cylinder 14 is fixedly connected to the inner wall of the connecting cylinder 4. A slide rod 15 is slidably connected inside the slide cylinder 14. One end of the slide rod 15 extends to the outside of the slide cylinder 14 and is fixedly connected to a push plate 16. A first sealing gasket 17 is fixedly connected to the side of the push plate 16 away from the slide rod 15.

[0028] A second spring 18 is fitted on the side surface of the slide cylinder 14. One end of the second spring 18 is fixedly connected to the inner wall of the connecting cylinder 4, and the other end of the second spring 18 is fixedly connected to the side of the push plate 16 near the slide rod 15. The side of the first sealing gasket 17 away from the push plate 16 is in contact with one end of the insert cylinder 3.

[0029] When the insert 3 is inserted into the inside of the connecting cylinder 4, it will come into contact with the first sealing gasket 17 and can squeeze the first sealing gasket 17 and the push plate 16, so that the two can move inside the connecting cylinder 4. The setting of the slide cylinder 14 and the slide rod 15 improves the stability of the push plate 16 when it moves. When the push plate 16 moves, it can compress the second spring 18. At the same time, the second spring 18 can always apply a reaction force to the push plate 16, so that the first sealing gasket 17 is in close contact with the insert 3, effectively reducing the possibility of the insert 3 rotating and deviating, and providing a guarantee for the insert 7 to smoothly enter the inside of the insertion hole 11.

[0030] It should be noted that, in order to reduce the possibility of sewage leakage, such as Figure 1 , Figure 2 and Figure 4 As shown, a sealing groove is provided on one side of the filter press body 1, and a second sealing gasket 19 is fixedly connected inside the sealing groove. One side of the second sealing gasket 19 is in contact with one side of the connecting cylinder 4.

[0031] The first sealing gasket 17 has a certain elastic deformation capability. After the connecting cylinder 4 is installed on the filter press body 1, the first sealing gasket 17 can fit tightly against the connecting cylinder 4, thereby improving the airtightness and effectively reducing the possibility of sewage leakage.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
