Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure filtration technology, and in particular to a pressure filtration device for industrial ceramic water mill wastewater. Background Technology
[0002] Industrial ceramic water milling wastewater refers to the wastewater generated during the production of industrial ceramics after ceramic blanks or finished products undergo water milling (wet grinding, polishing, and other processing steps). This type of wastewater typically contains large amounts of ceramic powder, abrasive particles (such as silicon carbide and alumina), and blank residue. Treatment of this type of wastewater generally employs pressure filtration. However, after the solid material is pressed into a filter cake, the cake is supported by the filter chamber, making it difficult to discharge and leading to filter cake residue that affects subsequent filtration processes. Utility Model Content
[0003] The purpose of this invention is to solve the shortcomings of the existing technology, which is that the filter cake is supported by the filter chamber, making it difficult to discharge the filter cake and easily causing filter cake residue, which affects the next filtration. Therefore, this invention proposes an industrial ceramic water mill wastewater pressure filter.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design an industrial ceramic water mill wastewater pressure filtration device, including a support frame, an inlet pipe installed on the support frame, multiple connecting boxes evenly spaced on the support frame, with every two connecting boxes facing each other, the inlet pipe connected to one of the connecting boxes, a moving mechanism on the support frame connecting the connecting boxes, a through hole on the connecting box, a connecting pipe abutting inside the through hole, a sealing ring on the connecting pipe, a filter plate fixedly connected to the connecting pipe, the filter plate dividing the connecting box into a drainage chamber and a filter chamber, multiple springs fixedly connected between the filter plate and the connecting box, and a collection mechanism on the support frame.
[0006] Preferably, the spring is a stainless steel spring.
[0007] Preferably, an abutment block is fixedly connected inside the connecting box, and the abutment block abuts against the filter plate.
[0008] Preferably, the moving mechanism includes a connecting rope, and two adjacent connecting boxes are connected by the connecting rope. Two support blocks are fixedly connected to each of the multiple connecting boxes. The two support blocks abut against a support frame. A hydraulic rod is fixedly connected to the support frame, and the hydraulic rod is connected to the connecting box.
[0009] Preferably, the filter plate is provided with filter cloth.
[0010] Preferably, the collection mechanism includes a drain pipe connected to the drain cavity, and a liquid collection tank is placed on the support frame, with the liquid collection tank located directly below the drain pipe.
[0011] Preferably, a solid collection box is provided directly below the connecting box.
[0012] Preferably, a sealing gasket is fixedly connected to the through hole.
[0013] The present invention provides an industrial ceramic water mill wastewater pressure filtration device with the following advantages: the various connecting boxes are separated, and under the action of the spring restoring force, the filter plate is pushed to move. The filter plate pushes the filter cake out of the filter chamber and into the solid collection box under the action of gravity, thus avoiding the residue of the filter cake and affecting the next filtration.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example 1: Refer to Figure 1-5An industrial ceramic water mill wastewater pressure filtration device includes a support frame 1, on which an inlet pipe 9 is installed. Multiple connection boxes 2 are evenly spaced on the support frame 1, with each pair of connection boxes 2 facing each other. The inlet pipe 9 is connected to one of the connection boxes 2 and is connected to a feed pump. The feed pump provides pressure to the wastewater, which enters the filter chamber 12. The water is filtered through the filter cloth of the filter plate 11, and solid matter is intercepted in the filter chamber. The water enters the drain chamber 15 and is collected by a collection mechanism.
[0022] A moving mechanism is installed on the support frame 1 to connect to the connecting box 2. The connecting box 2 has a through hole, and a connecting pipe 10 abuts inside the through hole. A sealing ring is installed on the connecting pipe 10, and a filter plate 11 is fixedly connected to the connecting pipe 10. A sealing layer made of rubber material is installed inside the connecting box 2, which serves to seal the filter plate 11. A filter cloth is installed on the filter plate 11, which divides the connecting box 2 into a drainage chamber 15 and a filter chamber 12. Multiple springs 13 are fixedly connected between the filter plate 11 and the connecting box 2. Spring 13 is made of stainless steel to prevent rust. A collection mechanism is provided on the support frame 1. After the filter press is completed, when the filter cake needs to be discharged, the connecting box 2 is moved by the moving mechanism to separate the connecting boxes 2. Spring 13 is compressed during the filter press. Under the action of the restoring force of spring 13, the filter plate 11 is pushed to move. The filter plate 11 pushes the filter cake out of the filter chamber and into the solid collection box 5 under the action of gravity, thus avoiding the residue of filter cake and affecting the next filtration.
[0023] A stop block 14 is fixedly connected inside the connecting box 2. The stop block 14 abuts against the filter plate 11. The stop block 14 protects the spring 13 and prevents the spring 13 from being over-compressed and damaged during filtration.
[0024] The moving mechanism includes a connecting rope 3, which connects two adjacent connecting boxes 2. Two support blocks 8 are fixedly connected to each of the multiple connecting boxes 2. Sealing gaskets are fixedly connected to the through holes. The sealing gaskets provide a sealing effect between the two connecting boxes. The two support blocks 8 abut against the support frame 1 respectively. A hydraulic rod 4 is fixedly connected to the support frame 1. The hydraulic rod 4 is connected to the connecting boxes 2. By extending the hydraulic rod 4, the connecting boxes 2 are brought together, allowing wastewater to enter the filter chamber through the through holes and connecting pipe 10. When the hydraulic rod 4 retracts, the connecting rope 3 will separate the adjacent connecting boxes 2.
[0025] Example 1: Refer to Figure 1-2As another preferred embodiment of the present invention, based on embodiment 1, the collection mechanism includes a drain pipe 7, which is connected to the drain chamber 15. A liquid collection tank 6 is placed on the support frame 1, which is located directly below the drain pipe 7. The liquid collection tank 6 collects the filtered liquid through the liquid collection tank 6, which is connected to an external water supply pipe.
[0026] A solid collection box 5 is located directly below the connecting box 2, and the solid collection box 5 collects the filter cake.
[0027] 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.
