[0002] High-voltage insulating materials refer to materials used for the insulation of high-voltage cables. They possess a series of important characteristics and functions to ensure the normal operation of electrical equipment and the safety and stability of the power system. During the underwater pelletizing process of high-voltage insulating materials, debris and dust are generated, and continuous filtration of the cooling circulating water is required. Therefore, the quality of the pelletizing cooling circulating water is crucial for the product quality and production efficiency.

[0003] However, traditional filtering devices often have problems such as discontinuous filtration and poor filtration effect, which affect the production stability and product performance. For the currently used high-voltage insulating water filtering device, the filter bag needs to be replaced in time when the pressure difference reaches 1.0 bar after a certain production time. Summary of the Utility Model

For the currently used high-voltage insulating water filtering device, the filter bag needs to be replaced in time when the pressure difference reaches 1.0 bar after a certain production time, and a continuous filtering device for the cooling circulating water of high-voltage insulating materials during pelletizing is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A continuous filtering device for the cooling circulating water of high-voltage insulating materials during pelletizing includes a water inlet pipe and a water outlet pipe. A first stainless steel filter, a second stainless steel filter, a third stainless steel filter, and a fourth stainless steel filter are connected between the water inlet pipe and the water outlet pipe through pipelines. The first stainless steel filter and the second stainless steel filter are located on the same side, the third stainless steel filter and the fourth stainless steel filter are located on the same side, and the first stainless steel filter, the second stainless steel filter, the third stainless steel filter, and the fourth stainless steel filter are all connected to the water outlet pipe through pipelines;

[0007] It further includes a dust collection water tank, and the first stainless steel filter, the second stainless steel filter, the third stainless steel filter, and the fourth stainless steel filter are all connected to the dust collection water tank through pipelines;

[0008] A switching component for switching the filtering position is arranged between the first stainless steel filter and the water outlet pipe;

[0009] A filtering component for filtering dust is arranged inside the dust collection water tank.

[0010] In a possible design, the switching component includes a first valve and a second valve. The first valve is arranged on the pipeline between the water inlet pipe and the first stainless steel filter and the second stainless steel filter, and the second valve is arranged on the pipeline between the water inlet pipe and the third stainless steel filter and the fourth stainless steel filter.

[0011] In a possible design, the switching component further includes a third valve and a fourth valve. The third valve is arranged on the pipeline between the water outlet pipe and the first stainless steel filter and the second stainless steel filter, and the fourth valve is arranged on the pipeline between the water outlet pipe and the third stainless steel filter and the fourth stainless steel filter.

[0012] In a possible design, the switching component further includes a fifth valve and a sixth valve. The fifth valve is arranged on the pipeline between the dust collection water tank and the first stainless steel filter and the second stainless steel filter, and the sixth valve is arranged on the pipeline connecting the dust collection water tank and the third stainless steel filter and the fourth stainless steel filter.

[0013] In a possible design, it further includes a first pressure gauge, a second pressure gauge, a third pressure gauge and a fourth pressure gauge. The first pressure gauge and the fourth pressure gauge are respectively arranged on the water inlet pipe and the water outlet pipe. The second pressure gauge is arranged on the pipeline connecting the water inlet pipe and the first stainless steel filter and the second stainless steel filter, and the third pressure gauge is arranged on the pipeline connecting the water inlet pipe and the third stainless steel filter and the fourth stainless steel filter.

[0014] In a possible design, the filtering component includes two fixed inclined plates respectively fixedly connected to the inner walls on both sides of the dust collection water tank. The same fixed strip plate is fixedly connected between the inner walls on both sides of the dust collection water tank. The same sliding inclined plate is slidably connected between the inner walls on both sides of the dust collection water tank. Two symmetrically arranged springs are fixedly connected between the sliding inclined plate and the fixed strip plate. The top of the sliding inclined plate abuts against the bottom of the fixed inclined plate.

[0015] In a possible design, a rectangular hole is opened on one side of the dust collection water tank. A sealing plate is clamped inside the rectangular hole.

The third stainless steel filter and the fourth stainless steel filter are reversely flushed in the same way; the first stainless steel filter and the second stainless steel filter are the same.

[0018] When the powder is collected in the dust collection water tank, at this time, the sewage carries the powder and enters the inside of the dust collection water tank together.

After the sliding inclined plate presses the spring, it can also enter the top of the filtering inclined plate through the gap between the fixed inclined plate and the sliding inclined plate. After being filtered through the filter holes, the filtered water can be collected at this time. When cleaning the filtering inclined plate, the filtering inclined plate can be pulled out horizontally through the handle, thereby improving the cleaning effect.
