Description

Technical Field

[0001] This utility model relates to a pipeline filter for ammonium polyvanadate slurry, belonging to the field of chemical media filtration technology in the metallurgical industry. Background Technology

[0002] During the transportation of ammonium polyvanadate slurry, due to the long service life of equipment such as reactors and thickeners, some internal anti-corrosion coatings and other materials in contact with the material may peel off. This peeling material enters the delivery pump along with the slurry, causing impeller blockage and reducing flow rate. This necessitates disassembling the delivery pump to clean the impeller, which can easily damage mechanical seals and other malfunctions. As the equipment ages, the anti-corrosion coating peels off more rapidly, exacerbating impeller blockage and requiring frequent pump disassembly. This leads to reduced equipment operating rates and increased labor intensity for personnel. To solve these problems, a pipeline filter that is easy to clean needs to be designed. Utility Model Content

[0003] The purpose of this invention is to provide a pipeline filter for ammonium polyvanadate slurry, which enables the ammonium polyvanadate slurry to pass through the filter quickly without affecting the flow rate of the pipeline medium. Large debris in the solution that easily clogs the impeller can be effectively filtered to prevent impeller blockage and solve the problems existing in the background technology.

[0004] The technical solution of this utility model is:

[0005] A pipeline filter for ammonium polyvanadate slurry includes a filter container, a top cover, a feed inlet, a drain pipe, a discharge inlet, and an exhaust pipe. The top cover is located on the top of the filter container, and the exhaust pipe is located on the top cover. The feed inlet and the drain pipe are located on one side of the filter container, and the discharge inlet is located on the other side of the filter container. The filter plate is longitudinally arranged inside the filter container, and the filter plate has evenly arranged round holes as filter holes.

[0006] The inner wall of the filter container is provided with a limiting groove that cooperates with the filter plate, and the filter plate slides up and down in the limiting groove.

[0007] The filter container is cylindrical, the filter plate is a rectangular plate that matches the filter container, and the limiting grooves are two oppositely arranged on the inner wall of the filter container.

[0008] The feed inlet and discharge outlet are located on opposite sides of the filter plate.

[0009] The drain pipe is located below the feed inlet.

[0010] The feed port is equipped with a feed pipe pressure gauge, and the discharge port is equipped with a discharge pipe pressure gauge.

[0011] A rubber sealing ring is provided between the upper cover and the filter container.

[0012] The beneficial effects of this utility model are:

[0013] (1) In this utility model, a removable filter plate is used to improve the strength and service life of the filter screen, which can ensure the large flow of ammonium polyvanadate slurry of solid-liquid mixture, and effectively intercept large debris that is easy to clog the impeller.

[0014] (2) In this utility model, by installing pressure gauges on the inlet and outlet pipes, the clogging of the filter plate can be effectively monitored;

[0015] (3) By adopting this utility model, the impeller of the delivery pump can be effectively blocked, and problems such as mechanical seal damage and realignment of the motor and pump shaft coupling during the disassembly of the delivery pump can be avoided, thereby improving the equipment operating rate and reducing labor intensity.

[0019] The present invention will be further described below with reference to the accompanying drawings and examples.

[0020] See attached document Figure 1-2 A pipeline filter for ammonium polyvanadate slurry includes a filter container 1, an upper cover 2, a feed inlet 3, a drain pipe 4, a discharge inlet 5, and an exhaust pipe 6. The filter container 1 is provided with an upper cover 2, and the upper cover 2 is provided with an exhaust pipe 6. The feed inlet 3 and the drain pipe 4 are provided on one side of the filter container 1, and the discharge inlet 5 is provided on the other side of the filter container 1. The filter plate 9 is arranged longitudinally inside the filter container 1, and the filter plate 9 is provided with evenly distributed round holes 12 as filter holes.

[0021] In this embodiment, refer to the appendix Figure 1-2 The ammonium polyvanadate slurry pipeline filter includes a filter container 1, an upper cover 2, an inlet port 3, a drain pipe 4, an outlet port 5, an exhaust pipe 6, an outlet pipe pressure gauge 7, an inlet pipe pressure gauge 8, a filter plate 9, a rubber sealing ring 10, a limiting groove 11, and a circular hole 12, wherein:

[0022] The filter container 1 is cylindrical, and the rubber sealing ring 10 is disposed between the upper cover 2 and the filter container 1. Two opposing limiting grooves 11 are provided on the inner wall of the filter container 1 along its axial direction.

[0023] The filter plate 9 is a rectangular steel plate that matches the filter container 1. Circular holes 12 are evenly arranged on the rectangular steel plate as filter holes. The two sides of the rectangular steel plate can slide up and down within the limiting groove 11.

[0024] The feed inlet 3 and the discharge inlet 5 are arranged opposite each other on both sides of the filter plate 9, and the drain pipe 4 is located below the feed inlet 3.

[0025] During operation, the ammonium polyvanadate slurry enters the filter through inlet pipe 3. At this time, the vent valve 6 of the upper cover 2 is opened to release the gas and prevent it from entering the delivery pump and causing impeller cavitation. The ammonium polyvanadate slurry passes through the filter plate 9, which blocks large impurities that could clog the impeller in the inlet chamber. The filtered slurry is discharged from the filter container outlet pipe 5 and enters the delivery pump through the pipeline.

[0026] Pressure gauges are installed on the feed inlet pipe 3 and the discharge inlet pipe 5 to monitor the pipeline pressure. By analyzing the pressure difference, the flow area of ​​the filter plate 9 is determined. When the pressure difference is small, the valves of the filter inlet and outlet pipes 3 are closed, the valve of the drain pipe 4 is opened, and the vent pipe 6 on the upper cover 2 is connected to high-pressure water. The filter plate 9 is cleaned by backwashing with high-pressure water, and the filter residue is discharged from the filter through the drain pipe 4 valve with the flushing water. When the pressure difference between the two gauges is large, the filter inlet and outlet valves are closed, the upper cover 2 is removed, and the filter plate 9 is taken out for cleaning. At the same time, debris in the liquid inlet chamber is cleaned. After cleaning, the filter plate 9 is reinstalled, and the upper cover 2 is reinstalled. Then, the valves of the feed inlet pipe 3 and the vent pipe 6 are opened, and the slurry enters the filter.
