[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a top cover processing coolant circulation filtration system, including a filter box 1 with an inlet channel 2 at the top for introducing coolant to be treated into the system. A storage tank 3 is installed inside the filter box, serving as a temporary storage and circulation hub for the coolant. The coolant is transported to the storage tank via a conveying channel 4 and a circulation pump 5, forming a closed-loop circulation. A coarse filtration unit, a fine filtration unit, and an activated carbon adsorption unit are connected in series between the inlet channel 2 and the storage tank 3. The coarse filtration unit intercepts and removes larger particulate impurities. The coolant after coarse filtration enters the fine filtration unit to further intercept smaller impurities. After fine filtration, the coolant enters the activated carbon adsorption unit, where organic matter and odors are effectively removed by the activated carbon adsorption blocks, achieving multi-stage filtration and purification.

[0020] Specifically, the arc-shaped filter screen 6 is located at the upper end of the filter box 1 and adopts an inclined design to facilitate the flow of coolant and intercept larger particulate impurities. The filter screen cleaning assembly 7 is used to clean the arc-shaped filter screen 6, including: a first drive motor 701 is installed on the filter box 1, with the drive end extending into the filter box 1 to drive the spiral conveyor 702 to operate; the spiral conveyor 702 is adapted to the arc-shaped filter screen 6 and pushes the impurities on the surface of the filter screen to the waste discharge port 703 by rotation; the waste discharge port 703 is located at the end of the filter box 1 away from the first drive motor 701 and is used to discharge the cleaned impurities; a first collection box 704 is located on the side wall below the waste discharge port 703 and is detachably connected to collect the waste generated during cleaning for centralized processing.

[0021] In practical use, the coolant first enters the coarse filtration unit, where the arc-shaped filter screen 6 removes large particles of impurities through physical interception. The first drive motor 701 drives the screw conveyor 702 to rotate, pushing the impurities on the surface of the arc-shaped filter screen 6 along an inclined direction to the waste discharge port 703. The impurities fall into the first collection box 704 through the waste discharge port 703, realizing automated cleaning, reducing manual intervention, and ensuring the efficiency of the filtration device.

[0022] Specifically, the fine filtration unit includes a conveying filter cloth 8 positioned below the arc-shaped filter screen 6. The conveying filter cloth 8 is supported by two side grooves 801, and a conveying roller 802 is installed inside the grooves 801. The roller rotation drives the filter cloth 804 to move. The filter cloth 804 is positioned between the two conveying rollers 802 as a filter medium to intercept fine impurities in the coolant. A second drive motor 803 is mounted on the filter box 1 to drive the rotation of one side of the conveying roller 802, thereby driving the filter cloth 8 to circulate. The filter box 1 is equipped with a mechanism for conveying the filter cloth 8. The filter cloth cleaning assembly 9 includes: an air chamber 901 located in a groove 801 on one side, inside the filter cloth 804, for storing high-pressure gas; an air inlet pipe 902 connected to the air chamber 901 to provide a source of clean air; nozzles 903 evenly distributed at the bottom of the air chamber 901, adapted to the filter cloth 8, and back-blowing the surface of the filter cloth 804 with high-pressure airflow; and a second collection box 904 located directly below the nozzles 903, which is detachably connected and used to collect fine particles that fall off during the cleaning process.

[0023] In practical use, the coolant enters the fine filtration unit after passing through the coarse filtration unit, where it is further intercepted by the conveying filter cloth 8. The filter cloth is continuously circulated by the conveying roller 802 to ensure filtration efficiency. Compressed air is injected into the air chamber 901 through the air inlet pipe 902 and evenly sprayed onto the inside of the filter cloth through the nozzle 903 to remove attached impurities. The fine particles generated during cleaning are blown off by the nozzle 903 into the second collection box 904, realizing automated cleaning and waste separation. The filter cloth 804 is continuously circulated by the conveying roller 802 to avoid clogging. The filter cloth cleaning component 9 is activated periodically to maintain filtration performance. Through the combination of mechanical transmission and airflow cleaning, deep filtration and efficient maintenance of the coolant are achieved, ensuring the efficiency of the filtration device.

[0024] Specifically, the activated carbon adsorption unit includes a collection hopper 10 disposed inside the conveying filter cloth 8. The collection hopper 10 is disposed inside the conveying filter cloth 8 and is used to receive the coolant after being treated by the fine filtration unit. A three-way valve 11 is provided at the bottom of the collection hopper 10. The three-way valve 11 realizes the diversion of coolant and the switching of the activated carbon adsorption module 12. Both output ends of the three-way valve 11 are provided with activated carbon adsorption modules 12. The activated carbon adsorption module 12 includes: a filter chamber 1201 connected to the three-way valve 11, and filled with activated carbon adsorption blocks 1203. The filter chamber 1201 is used to adsorb organic matter and odors in the coolant. The upper end of the side wall of the filter chamber 1201 is connected to the three-way valve 11, and the bottom of the filter chamber 1201 is connected to the liquid storage tank 3 to ensure that the filtered coolant flows back to the liquid storage tank 3. The sealing mounting seat 1202 is set at the open end of the filter chamber 1201 and is installed by insertion to facilitate quick replacement of the activated carbon adsorption block 1203. The activated carbon adsorption block 1203 is adapted to the inside of the filter chamber 1201 and is fixed by the sealing mounting seat 1202 to ensure the sealing and high efficiency of the adsorption process.

[0025] In practical use, the coolant treated by the fine filtration unit enters the collection hopper 10 and is diverted to one of the two activated carbon adsorption modules 12 through the three-way valve 11. The coolant comes into contact with the activated carbon adsorption block 1203 in the filter chamber 1201, and organic matter and odors are adsorbed and removed. When one activated carbon adsorption module needs to be replaced, the three-way valve 11 switches to the other module to ensure continuous operation of the system without shutdown. The filtered coolant flows back to the storage tank 3 from the bottom of the filter chamber 1201 through the pipeline to complete the circulation. The two activated carbon adsorption modules 12 are used alternately through the three-way valve 11 to ensure the continuous operation capability of the system when replacing consumables.

[0026] Working principle: When this utility model is in operation, the coolant enters the filter box 1 through the inlet channel 2. First, it passes through the arc-shaped filter screen 6 to physically intercept and remove large particulate impurities in the coolant. At the same time, the filter screen cleaning component 7 automatically cleans the impurities on the surface of the filter screen. The coolant after coarse filtration flows into the fine filtration unit, where it is further intercepted by the filter cloth 8. The filter cloth cleaning component 9 is activated periodically to remove residual impurities. The coolant after fine filtration enters the activated carbon adsorption unit and flows into the three-way valve 11 through the collection hopper 10. The three-way valve 11 diverts the coolant to one of the two activated carbon adsorption modules 12 to adsorb organic matter, odors and trace impurities in the coolant. The filtered coolant flows back from the bottom of the filter chamber to the storage tank 3, completing the circulation.
