[0023] Reference Figure 1 , Figure 2 and Figure 4As shown, a cooling water circulation filtering device of an air separation equipment includes a cooling furnace 1, a water outlet pipe 11 is arranged at the lower end of the cooling furnace 1, a filtering device 2 is installed at the lower end of the water outlet pipe 11, the filtering device 2 includes a filter box 21 and a filter screen plate 22, the filter screen plate 22 is tiltedly arranged in the filter box 21, and one end of the filter screen plate 22 is rotatably connected to the filter box 21, and the other end is connected to the filter box 21 through a buffer assembly 23, a collecting shell 3 is also arranged at the lower end of the filter screen plate 22, and a plurality of drainage shells 4 are also arranged on the lower end surface of the filter box 21. By installing a filter device 2 on the outlet pipe 11 at the lower end of the cooling furnace 1, it is ensured that the cooling water discharged from the cooling furnace 1 can enter the filter device 2. By setting the structure of the filter device 2, it is ensured that the filter screen plate 22 is installed in the filter box 21, so that the incoming cooling water can be filtered through the filter screen plate 22. At the same time, one end of the filter screen plate 22 is rotatably connected to the filter box 21, and the other end is connected to the filter box 21 through a buffer component 23. In this way, it can be ensured that the filter screen plate 22 can move within a certain angle during the sewage filtering process. When sewage enters and falls on the filter screen plate 22, the filter screen plate 22 can be flipped downward, and when the water intake stops, the filter screen plate 22 can be flipped upward under the pull of the buffer component 23, or it can be flipped according to the size of the incoming water flow. This not only ensures a good filtering effect, but also ensures that the impurities on the filter screen plate 22 can stably slide along the direction of the filter screen plate 22 into the collection shell 3. By setting a plurality of drainage shells 4 on the lower end surface of the filter box 21, it is easy to divert and discharge the filtered cooling water.

[0024] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the filter box 21 includes a box shell 211 and an outer cover 212, the outer cover 212 is installed on the front end surface of the box shell 211, and the outer cover 212 is sealed and fixedly connected to the box shell 211.

A connecting sleeve 221 is fixedly installed at one end of the filter screen plate 22, and a positioning shaft 213 for rotating the connecting sleeve 221 is provided on the inner side of the box shell 211, and the positioning shaft 213 is fixedly connected to the box shell 211. By arranging the connecting sleeve 221 on the filter screen plate 22, it is convenient to sleeve the connecting sleeve 221 on the positioning shaft 213 on the inner side of the box shell 211, so that the filter screen plate 22 can be flexibly turned over when in use.

The collecting shell 3 is structurally arranged to ensure that the bracket 31 is installed in the box shell 211, so that the mesh shell 32 can be positioned and placed by the bracket 31 to ensure that the mesh shell 32 can stably receive the filtered impurities, and the bracket 31 can also be used to assist in limiting the filter screen plate 22 to prevent the filter screen plate 22 from flipping to the bottom. The upper end surface of the box shell 211 is provided with a liquid inlet pipe 214 connected to the water outlet pipe 11. The setting of the liquid inlet pipe 214 ensures that the cooling water is stably introduced into the box shell 211 in cooperation with the water outlet pipe 11.

The structure of the buffer assembly 23 is set to ensure that the tension spring 232 is installed through the fixed seat 231, and it is convenient to assist in lifting the free end of the filter screen plate 22 through the tension spring 232, so that when the filter screen plate 22 is stressed, the tension spring 232 can be stretched, and when it is not stressed, the tension spring 232 can lift the free end of the filter screen plate 22, so that the filter screen plate 22 can be flipped back and forth within a certain angle. The outer cover 212 is provided with a transparent window 215 corresponding to the mesh shell 32, and the transparent window 215 is sealed and fixedly connected to the outer cover 212. The transparent window 215 is provided to facilitate the operator to observe the storage of impurities in the mesh shell 32 from the outside. When a certain amount of impurities is stored in the mesh shell 32, the outer cover 212 can be removed, so that the mesh shell 32 can be pulled out from the bracket 31 through the outer cover 212 for easy cleaning.

[0027] Working principle: When cooling water is needed from the cooling furnace, the water outlet pipe can be opened, and the coolant can be introduced into the filter box through the cooperation of the water outlet pipe and the liquid inlet pipe. Then, the filter screen can be used to achieve stable filtering operation. The filtered coolant can be stably discharged from the discharge shell at the lower end, and the filtered impurities can slide along the filter screen into the mesh shell of the collection shell.
