[0019] The detailed connection means are well known in the art. The following mainly introduces the working principle and process, which are as follows:

[0020] According to the instruction manual Figure 1-2 As can be seen, during installation, the filter screen 9 is removably mounted within the primary filter chamber 2, with the collection screen 18 seated within the groove 19. The precision filter plate 15 is supported by support rods 17 and support rings 16, and the upper edge of the precision filter plate 15 is locked in place by a locking assembly. During operation, wastewater is injected through the water inlet 10 on the end cap 8 above the primary filter chamber 2. Here, the water inlet 10 is connected to the wastewater outlet of the CNC machine tool, which is conventional technology. The wastewater entering the water inlet 10 is filtered through the filter screen 9 from top to bottom. The filter screen 9 filters out large impurities. The large impurities are intercepted and the wastewater enters the secondary filter chamber 13 from the horizontal opening 1 at the lower end of the partition 4, is filtered through the precision filter plate 15 from bottom to top, and is discharged from the water outlet 14. It should be noted here that the filter screen 9 is higher than the water level of the wastewater in the filter box 3, so as to achieve the purpose of directly passing through large impurities for cleaning, avoiding long-term mixing and dissolution in the filter box 3, and increasing the filtering burden of the precision filter plate 15; the water outlet 14 is higher than the precision filter plate 15 and lower than the water level of the wastewater in the filter box 3, and the precision filter plate is lower than the water level of the wastewater in the filter box 3, so that the filtered water can be discharged from the filter box 3, and the water inlet of the primary filter chamber 2 flows to the bottom of the precision filter plate 15 and applies pressure. The pressure is greater than the water filtered on the upper part of the precision filter plate 15, and the filtered water will be discharged immediately, so as to ensure the above flow direction and the smooth progress of the work. Wastewater is filtered from bottom to top through the precision filter plate 15. Impurities at the bottom of the precision filter plate 15 will sink due to gravity, avoiding accumulation on the precision filter plate 15 and causing blockage, thereby improving the filtering effect. Moreover, the sunken impurities will fall into the collection net 18, making it easier for personnel to clean and discharge the filter box 3. In the present utility model, the end cover 8 can be opened, and the filter net 9, precision filter plate 15 and collection net 18 can be removed from the top of the filter box 3 for cleaning. In particular, the collection net 18 can remove impurities settled at the bottom of the precision filter plate 15, thereby improving the cleanliness of the filter box 3.

[0021] Among them, the filter screen 9 is set at an angle, and the filter box 3 is provided with an impurity outlet 7 at the position corresponding to the downward tilt of the filter screen 9. The outside of the filter box 3 is provided with a collecting box 5 at the position corresponding to the impurity outlet 7. A box door 6 is provided on one side of the collecting box 5. The wastewater passes through the inclined filter screen 9 to intercept large impurities in the wastewater, and guides it into the collecting box 5 through the impurity outlet 7. The box door 6 is opened to clean the impurities, which is simple and convenient, improves the cleanliness of the filter box 3, and improves the filtering effect.

[0022] Among them, the locking assembly includes a compression spring 21 and a limiting ball 20. A plurality of mounting grooves 22 are provided on the side walls of the filter box 3 and the partition 4, and the mounting groove 22 corresponds to the upper edge position of the precision filter plate 15. The compression spring 21 is arranged in the mounting groove 22, and the outer end of the compression spring 21 is fixedly connected to the limiting ball 20. The compression spring 21 can enable the limiting ball 20 to lock the precision limiting plate in the vertical direction under the action of non-external force, thereby ensuring the stability of the precision filter plate 15 under non-human external force, and convenient disassembly and installation.

[0023] Among them, a supporting plate 11 is provided in the primary filter chamber 2, and the supporting plate 11 is fixedly connected to the filter box and the partition 4, and the filter screen 9 is arranged on the supporting plate 11, which is convenient for installation and disassembly.

[0024] A water level monitor 12 is installed on the partition 4, corresponding to the side wall of the primary filter chamber 2. This monitor is used to monitor the wastewater level, transmit signals, and control external water inflow. Both the water inlet 10 and the water outlet 14 are equipped with valves, which are conventional technology. The water level monitor 12 ensures water pressure and continuous and stable operation. Of course, a water level monitor 12 can also be installed under the end cap 8 above the secondary filter chamber 13 to monitor the water level on the outlet side as a reference and comparison for the wastewater level.
