Description

Technical Field

[0001] This application relates to the technical field of star wheel sheet processing, and particularly to a processing technology for star wheel sheets of single-screw compressors. Background Art

[0002] With the development of industrial automation and precision manufacturing technologies, single-screw compressors, as key equipment for process gas treatment in the chemical industry, have received increasing attention for their performance and efficiency. As a core component of single-screw compressors, the meshing motion between the star wheel sheet and the screw directly affects the stability and efficiency of the compressor. Since the star wheel sheet needs to work in harsh environments such as flammable, explosive, toxic, and corrosive conditions, strict requirements are imposed on the material selection and processing technology. PEEK engineering plastics have become an ideal material for manufacturing star wheel sheets due to their excellent corrosion resistance, wear resistance, vibration damping performance, and stable machining and cutting performance. In order to achieve precision machining of star wheel sheets, advanced five-axis machining centers and digital machining control technologies are adopted to improve machining efficiency and ensure the correctness and reliability of machining programs.

[0003] In existing processing technologies, the finish machining of star wheel sheets mainly relies on five-axis machining center machines. The 3D model of the star wheel sheet is constructed through the software's three-dimensional modeling module, and the software's motion simulation module is used to check the rotational interference problems of the model. Subsequently, the machining program for the five-axis machining center machine and the program list for the five-axis turning and milling composite machine are compiled using the CAM module of the machining software, thus replacing the traditional manual programming calculation method and reducing uncertainties and errors. Before five-axis finish machining, finish turning is usually used as a pretreatment step. The star wheel sheet is clamped using a tooling plate and the process holes machined by a CNC milling machine to ensure the positioning accuracy of the star wheel sheet during the lathe machining process, and the two end faces of the star wheel sheet are machined on the lathe to form the required accuracy, laying a foundation for the subsequent five-axis finish machining. During the finish turning process, liquid cooling is widely used to reduce the temperature at the machining end and flush away the debris generated by cutting on the surface of the star wheel sheet.

[0004] Although existing processing technologies are quite mature, there are still some challenges during the finish turning process. In order to reduce coolant emissions and save costs, the coolant is usually recycled. The traditional filter screen filtration system has limitations in removing particles and impurities in the coolant, and some tiny metal debris can pass through the filter screen and re-enter the coolant circulation system. These tiny debris may cause wear on the grinding surface of the star wheel sheet during finish turning, affecting the accuracy of finish turning. Summary of the Invention

[0005] The purpose of this application is to provide a processing technology for the star wheel of a single-screw compressor to solve the problem that metal chips can penetrate the filter screen and may cause wear to the grinding surface of the star wheel during precision turning, affecting the precision of precision turning.

[0006] To achieve the above purpose, this application specifically adopts the following technical solutions: A processing technology for the star wheel of a single-screw compressor includes a floor filter table. The bottom of the floor filter table is fixedly connected with [the relevant part not provided in the original].

The bottom of the filter bin is fixedly connected with a circulation pump. The output end of the circulation pump is fixedly connected with a heat exchange pipe. The heat exchange pipe is buried underground. The output end of the heat exchange pipe extends to the ground surface and is fixedly connected with a water supply pipe. The inner top of the filter bin is symmetrically and fixedly connected with reciprocating sliding rods. One end of the two reciprocating sliding rods is slidably connected with a first filter screen. The interior of the filter bin is rotatably connected with a circulation roller. The interior of the filter bin is fixedly connected with an arc-shaped mounting plate. One end of the arc-shaped mounting plate is fixedly connected with an electromagnet. A circulation belt is sleeved around the circulation roller, the arc-shaped mounting plate, and the electromagnet. The interior of the filter bin is fixedly connected with an arc-shaped fine-rate water-permeable net. And a rubber scraping plate is fixedly connected to the interior of the filter bin. The rubber scraping plate is installed between the circulation belt and the arc-shaped fine-rate water-permeable net. The outside of [the relevant part not provided in the original] is fixedly connected with a circulation motor. The output end of the circulation motor is fixedly connected with the circulation roller. The steps are as follows: Step 1: Inspect the appearance shape and size of the star wheel to ensure the quality of the raw materials. Step 2: Use a CNC milling machine to drill process holes, which will be used for the positioning and clamping of subsequent precision turning. Step 3: Clamp through the tooling plate and process holes, and the lathe processes both end faces to form a deflection. During this process, the tool needs to have high wear resistance to meet the processing requirements. Step 4: During the processing of Step 3, connect a water supply nozzle with the water supply pipe, then start the circulation pump to cool the filtered coolant inside through the heat exchange pipe using geothermal energy, and then guide it to the surface of the star wheel being processed through the water supply pipe and the water supply nozzle to cool the star wheel and wash away the chips generated during the processing of the star wheel surface. Step 5: Make the coolant carry the chips and flow through the porous support plate and into the interior of the water collection bin and then into the filter bin. At the same time, the coolant flowing into the interior of the filter bin is preliminarily filtered by the first filter screen, so that the chips intercepted by the first filter screen slide down under the action of gravity into the interior of the arc-shaped fine-rate water-permeable net for filtration and collection, and the coolant preliminarily filtered by the first filter screen flows along the inclined surface of the circulation belt towards the inner bottom of the filter bin. Step 6: Start the electromagnet simultaneously to magnetically adsorb the tiny metal debris in the coolant flowing through the surface of the circulating belt. Then start the circulating motor to drive the circulating roller, cooperate with the arc-shaped mounting plate and the electromagnet to drive the circulating belt to move in a cycle, and make the circulating belt drive the tiny gold debris adsorbed by the electromagnet to move towards the direction of the rubber scraper; Step 7: Then, make the debris adsorbed by the electromagnet on the surface of the circulating belt be scraped by the rubber scraper, and slide into the interior of the arc-shaped fine-rate water-permeable net under the action of gravity for filtering and collection; Step 8: Use the software 3D modeling module to construct the 3D model of the star wheel piece, use the software motion simulation module to check the rotation interference problem of the 3D model, use the CAM module of the processing software to write the processing program of the five-axis machining center machine tool, and use the software drawing module to write the program list of the five-axis turning and milling compound machine tool to improve the processing efficiency through digital processing control, and ensure the correctness and reliability of the processing program; Step 9: Use an advanced three-coordinate measuring instrument to measure the cylindrical envelope surface size of the star wheel piece to ensure that the machining accuracy is within 0.02 MM, verify the consistency between the 3D model and the star wheel piece machined by the five-axis turning center machine tool, and ensure that the running clearance of the compressor meets the R & D requirements; Step 10: Mark and register the machined star wheel piece to ensure the traceability of the parts.

[0007] Further, one end of the first filter screen is symmetrically and fixedly connected with a reciprocating spring. The reciprocating spring is sleeved on one end of the reciprocating slide rod. A hexagonal wheel is rotatably connected inside the filter chamber. One end of the first filter screen is fixedly connected with a rubber contact block adapted to the hexagonal wheel. One end of the circulating roller is provided with a transmission component for driving the hexagonal wheel to rotate.

[0008] By adopting the above technical solution, through the combined use of the transmission component with the hexagonal wheel and the reciprocating spring, when starting the circulating motor to drive the circulating roller to rotate, it is convenient to drive the hexagonal wheel to push the rubber contact block to drive the first filter screen to move along the length direction of the reciprocating slide rod, and cooperate with the reciprocating spring to rebound and push the first filter screen to form continuous vibration along the length direction of the reciprocating slide rod, so that the foreign matters adhered to the surface of the first filter screen quickly fall off, effectively reducing the blockage on the surface of the first filter screen, improving the filtering efficiency of the first filter screen, and further reducing the problem that the debris causes wear to the star wheel piece and affects the machining accuracy of the star wheel piece.

[0009] Further, the transmission component includes a first synchronous wheel fixedly connected to one end of the circulating roller, a second synchronous wheel fixedly connected to one end of the hexagonal wheel, and a synchronous belt sleeved on the outer periphery of the first synchronous wheel and the second synchronous wheel.

[0010] By adopting the above technical solution, through the coordinated use of the synchronous belt with the second synchronous pulley and the first synchronous pulley, when starting the circulating motor to drive the circulating roller to rotate, the first synchronous pulley is driven to cooperate with the synchronous belt to drive the second synchronous pulley to rotate, and the second synchronous pulley drives the hexagonal wheel to rotate, thereby facilitating the driving of the hexagonal wheel to rotate, effectively improving the practicability of the device.

[0011] Further, the diameter of the first synchronous pulley is larger than that of the second synchronous pulley.

[0012] By adopting the above technical solution, by setting the diameter of the first synchronous pulley to be larger than that of the second synchronous pulley, when the first synchronous pulley drives the second synchronous pulley to rotate through the synchronous belt, the rotation speed of the second synchronous pulley is effectively increased, improving the practicability of the device.

[0013] Further, a plurality of drainage plates are uniformly and fixedly connected inside the filter chamber. The drainage plates are installed on the top of the circulating belt. Adjacent two drainage plates are arranged staggeredly, and an S-shaped drainage channel is formed. A first flow groove is opened at the bottom of the drainage plate.

[0014] By adopting the above technical solution, through the coordinated use of the drainage plates and the S-shaped drainage channel, the flow stroke of the coolant on the top of the circulating belt is effectively extended, so that the metal debris in the coolant is more comprehensively adsorbed by the electromagnet, further improving the adsorption accuracy of the electromagnet for the metal debris in the coolant and improving the practicability of the device.

[0015] Further, a sewage collection box communicated with the output end of the arc-shaped fine-rate water-permeable net is fixedly connected to one side of it. A sewage auger is rotatably connected inside the arc-shaped fine-rate water-permeable net. A sewage motor is fixedly connected to one side of it, and the output end of the sewage motor is fixedly connected to the sewage auger.

[0016] By adopting the above technical solution, through the coordinated use of the sewage auger and the arc-shaped fine-rate water-permeable net, starting the sewage motor can drive the sewage auger to push the debris collected inside the arc-shaped fine-rate water-permeable net to move along the length direction of the arc-shaped fine-rate water-permeable net into the sewage collection box, effectively improving the practicability of the device.

[0017] Further, a plurality of first slow-wave plates are uniformly and fixedly connected to one end inside the water collection chamber, and a plurality of second slow-wave plates are uniformly and fixedly connected to one end inside the water collection chamber. The plurality of first slow-wave plates and the plurality of second slow-wave plates are arranged staggeredly. Flow grooves are opened at the bottoms of the first slow-wave plates and the second slow-wave plates.

[0018] By adopting the above technical solution, through the combined use of the second slow wave plate and the first slow wave plate, it is convenient to collide and decelerate the coolant passing through the inside of the water collecting bin, reduce the impact force when the coolant flows into the inside of the filtering bin, and make the coolant slowly flow into the inside of the filtering bin and collide with the surface of the first filter screen for filtering, effectively improving the filtering effect of the first filter screen.

[0019] Furthermore, the surfaces of the platform filter table, the first filter screen, the circulating roller, the electromagnet, and the arc-shaped fine-rate water-permeable net are all coated with silicone waterproof paint.

[0020] By adopting the above technical solution, by setting the silicone waterproof paint, the waterproof effect of the device is effectively improved, and the service life of the device is prolonged.

[0021] In summary, the present application includes at least one of the following beneficial effects: 1. By setting the combined use of the heat exchange tube, the first filter screen, the circulating roller, the arc-shaped mounting plate, the electromagnet, the arc-shaped fine-rate water-permeable net, and the rubber scraper, it is convenient to preliminarily filter the coolant by using the first filter screen when guiding the coolant to flow into the inside of the filtering bin through the water collecting bin, so that the debris filtered out by the first filter screen falls into the inside of the arc-shaped fine-rate water-permeable net for collection. At the same time, the electromagnet is used to cooperate with the circulating belt to magnetically attract the tiny metal debris in the coolant. When the circulating motor is started to drive the circulating belt to move cyclically around the circulating roller and the arc-shaped mounting plate, the tiny metal debris is scraped off by the rubber scraper and falls into the inside of the arc-shaped fine-rate water-permeable net for collection. Then, the circulating pump is started to make the filtered coolant inside pass through the heat exchange tube to exchange heat and cool down by using the ground energy, and then it is guided to the surface of the star wheel piece in the processing for cooling through the water supply pipe and the water supply nozzle. In this way, the electromagnet is used to cooperate with the first filter screen and the arc-shaped fine-rate water-permeable net to form a fine filtration of the tiny metal debris, reducing the situation of abrasion on the surface of the star wheel piece when the coolant is recycled, and improving the precision of the finish turning process.

[0022] 2. By setting the combined use of the transmission component, the hexagonal wheel, and the reciprocating spring, it is convenient to drive the hexagonal wheel to push the rubber contact block to drive the first filter screen to move along the length direction of the reciprocating slide rod when the circulating motor is started to drive the circulating roller to rotate, and cooperate with the reciprocating spring to rebound and push the first filter screen to form continuous vibration along the length direction of the reciprocating slide rod, so that the foreign matters adhered to the surface of the first filter screen quickly fall off, effectively reducing the situation of blockage on the surface of the first filter screen, improving the filtering efficiency of the first filter screen, and further reducing the problem that the debris causes abrasion to the star wheel piece and affects the processing precision of the star wheel piece.

[0023] 3. By setting the combined use of the drainage plate and the S-shaped drainage channel, the flow stroke of the coolant on the top of the circulating belt is effectively extended, so that the metal debris in the coolant is more comprehensively adsorbed by the electromagnet, further improving the adsorption precision of the electromagnet for the metal debris in the coolant and improving the practicability of the device.

[0032] The embodiment of the present application discloses a processing technology for the star wheel blade of a single-screw compressor.

[0033] Referring to Figure 1 - Figure 3, A processing technology for star wheel blades of a single-screw compressor, including a floor filter table 1. A 2 is fixedly connected to the bottom of the floor filter table 1. A water collection chamber 3 is provided inside the 2.

A first filter screen 11 is slidably connected to one end of the two reciprocating slide bars 10. A circulation roller 12 is rotatably connected inside the filter chamber 6. An arc-shaped mounting plate 13 is fixedly connected inside the filter chamber 6. An electromagnet 14 is fixedly connected to one end of the arc-shaped mounting plate 13.

An arc-shaped fine-rate water-permeable net 16 is fixedly connected inside the filter chamber 6. And a rubber squeegee 17 is fixedly connected inside the filter chamber 6. The rubber squeegee 17 is installed between the circulation belt 15 and the arc-shaped fine-rate water-permeable net 16. A circulation motor 18 is fixedly connected to the outside of the 2. The output end of the circulation motor 18 is fixedly connected to the circulation roller 12, including the following steps: Step 1: Inspect the appearance shape and size of the star wheel blade to ensure the quality of the raw material; Step 2: Use a CNC milling machine to drill process holes, which will be used for positioning and clamping in subsequent finish turning; Step 3: Clamp through the tooling plate and process holes, and the lathe processes both end faces to form a deflection. During this process, the tool needs to have high wear resistance to meet the processing requirements; Step 4: During the processing in Step 3, connect the water supply nozzle with the water supply pipe 9, and then start the circulation pump 7 to pass the filtered coolant inside the 2 through the heat exchange tube 8 to cool down using geothermal energy, and then guide it to the surface of the star wheel blade being processed through the water supply pipe 9 and the water supply nozzle to cool the star wheel blade and wash away the chips generated during the processing of the star wheel blade surface; Step 5: Make the coolant carry the chips and flow through the porous support plate 5 and into the water collection chamber 3 and then into the filter chamber 6. At the same time, make the coolant flowing into the filter chamber 6 be preliminarily filtered by the first filter screen 11, so that the chips intercepted by the first filter screen 11 slide down under the action of gravity into the inside of the arc-shaped fine-rate water-permeable net 16 for filtering and collection, and make the coolant preliminarily filtered by the first filter screen 11 flow along the inclined surface of the circulation belt 15 towards the inner bottom of the filter chamber 6; Step 6: Start the electromagnet 14 simultaneously to magnetically adsorb the tiny metal debris in the coolant flowing through the surface of the circulating belt 15. Then start the circulating motor 18 to drive the circulating roller 12 to cooperate with the arc-shaped mounting plate 13 and the electromagnet 14 to drive the circulating belt 15 to move in a cycle, and make the circulating belt 15 drive the tiny gold debris adsorbed by the electromagnet 14 to move towards the rubber scraper 17; Step 7: Then, the debris adsorbed by the electromagnet 14 on the surface of the circulating belt 15 is scraped by the rubber scraper 17 and slides into the interior of the arc-shaped fine-permeable water net 16 under the action of gravity for filtration and collection; Step 8: Use the software three-dimensional modeling module to construct the 3D model of the star wheel piece, use the software motion simulation module to check the rotation interference problem of the 3D model, use the CAM module of the processing software to write the processing program of the five-axis machining center machine tool, and use the software drawing module to write the program list of the five-axis turning and milling composite machine tool to improve the processing efficiency through digital processing control and ensure the correctness and reliability of the processing program; Step 9: Use an advanced three-coordinate measuring instrument to measure the cylindrical envelope surface size of the star wheel piece to ensure that the machining accuracy is within 0.02 MM, verify the consistency between the three-dimensional model and the star wheel piece machined by the five-axis turning center machine tool, and ensure that the compressor operation clearance meets the R & D requirements; Step 10: Mark and register the machined star wheel piece to ensure the traceability of the parts.

[0034] Refer to Figure 1 - Figure 4 One end of the first filter screen 11 is symmetrically and fixedly connected with a reciprocating spring 19. The reciprocating spring 19 is sleeved on one end of the reciprocating slide bar 10. A hexagonal wheel 20 is rotatably connected inside the filter bin 6. One end of the first filter screen 11 is fixedly connected with a rubber abutting block 21 adapted to the hexagonal wheel 20. One end of the circulating roller 12 is provided with a transmission assembly for driving the hexagonal wheel 20 to rotate; Among them, the transmission assembly includes a first synchronous wheel 22 fixedly connected to one end of the circulating roller 12. One end of the hexagonal wheel 20 is fixedly connected with a second synchronous wheel 23. A synchronous belt 24 is sleeved on the peripheries of the first synchronous wheel 22 and the second synchronous wheel 23; Moreover, the diameter of the first synchronous wheel 22 is larger than that of the second synchronous wheel 23.

[0035] During use, when the circulating motor 18 is started to drive the circulating roller 12 to rotate, and in cooperation with the arc-shaped mounting plate 13 and the electromagnet 14 to drive the circulating belt 15 to move in a cycle, the circulating roller 12 drives the first synchronous wheel 22 to rotate. At the same time, the first synchronous wheel 22 cooperates with the synchronous belt 24 to drive the second synchronous wheel 23 to rotate. By using the diameter difference between the first synchronous wheel 22 and the second synchronous wheel 23, the rotation speed of the second synchronous wheel 23 is increased. Thus, the second synchronous wheel 23 drives the hexagonal wheel 20 to rotate rapidly, and the hexagonal wheel 20 collides with the rubber contact block 21. At the same time, the rubber contact block 21 is pushed to drive the first filter screen 11 to move along the length direction of the reciprocating slide bar 10, and the reciprocating spring 19 is compressed to generate a contraction deformation. Then, by using the elastic return characteristic of the reciprocating spring 19, the reciprocating spring 19 rebounds to push out the first filter screen 11 along the length direction of the reciprocating slide bar 10. In this way, the first filter screen 11 continuously vibrates along the length direction of the reciprocating slide bar 10, so that the foreign matters adhered to the surface of the first filter screen 11 quickly fall off and slide into the interior of the arc-shaped fine-rate water-permeable net 16 for interception and collection. Furthermore, the situation of blockage on the surface of the first filter screen 11 is effectively reduced, the filtering efficiency of the first filter screen 11 is improved, and the problem that the debris wears the star wheel piece and affects the processing accuracy of the star wheel piece is further reduced.

[0036] Refer to Figure 2 and Figure 3 , Figure 5 , a plurality of drainage plates 25 are uniformly and fixedly connected inside the filtering bin 6. The drainage plates 25 are installed on the top of the circulating belt 15. Adjacent two drainage plates 25 are arranged staggeredly and form an S-shaped drainage channel. A first flow groove 26 is opened at the bottom of the drainage plate 25.

[0037] During use, when the coolant gathers into a water flow and passes through the first filter screen 11 and falls onto the top of the circulating belt 15, the coolant flows along the S-shaped drainage channel formed between the plurality of drainage plates 25. Thus, the travel of the coolant flowing through the top of the circulating belt 15 is effectively extended, and the metal debris in the coolant is more comprehensively adsorbed by the electromagnet 14. At the same time, the metal debris on the surface of the circulating belt 15 can move toward the direction of the rubber scraper 17 through the first flow groove 26 when the circulating roller 12 is started to drive the circulating belt 15 to move in a cycle. In this way, the adsorption accuracy of the electromagnet 14 for the metal debris in the coolant is further improved, and the practicability of the device is enhanced.

[0038] Refer to Figure 1 and Figure 2 , Figure 6 , a dirt collection box 27 communicated with the output end of the arc-shaped fine-rate water-permeable net 16 is fixedly connected to one side of 2. A sewage auger 28 is rotatably connected inside the arc-shaped fine-rate water-permeable net 16. A sewage motor 29 is fixedly connected to one side of 2. The output end of the sewage motor 29 is fixedly connected to the sewage auger 28.

[0039] During use, when there is a large amount of debris collected inside the arc-shaped fine-rate water-permeable net 16, starting the sewage discharge motor 29 can drive the sewage discharge auger 28 to rotate, and push the debris collected inside the arc-shaped fine-rate water-permeable net 16 to move along the length direction of the arc-shaped fine-rate water-permeable net 16 into the sewage collection box 27, effectively improving the practicability of the device.

[0040] Refer to Figure 1 and Figure 2 , Figure 7 , a plurality of first slow-wave plates 30 are uniformly fixedly connected to one end inside the water collection chamber 3, and a plurality of second slow-wave plates 31 are uniformly fixedly connected to one end inside the water collection chamber 3. The plurality of first slow-wave plates 30 and the plurality of second slow-wave plates 31 are arranged alternately, and flow grooves two 32 are formed at the bottoms of the first slow-wave plates 30 and the second slow-wave plates 31.

[0041] During use, when the coolant flows through the water collection chamber 3 and into the filtration chamber 6, the coolant collides with the plurality of second slow-wave plates 31 and the flow grooves two 32 in turn along the length direction of the water collection chamber 3 to slow down the flow impact intensity of the coolant, so that the coolant slowly flows into the filtration chamber 6 and collides with the surface of the first filter screen 11 for filtration, further improving the filtration effect of the first filter screen 11, and the coolant remaining inside the water collection chamber 3 can flow through the flow grooves two 32 into the filtration chamber 6 for filtration circulation.

[0042] Refer to Figure 1 and Figure 2 , the surfaces of the floor filtration table 1, the first filter screen 11, the circulation roller 12, the electromagnet 14, and the arc-shaped fine-rate water-permeable net 16 are all coated with silicone waterproof paint.

[0043] During use, by coating the surfaces of the floor filtration table 1, the first filter screen 11, the circulation roller 12, the electromagnet 14, and the arc-shaped fine-rate water-permeable net 16 with silicone waterproof paint, a waterproof protective layer is formed on the surfaces of the floor filtration table 1, the first filter screen 11, the circulation roller 12, the electromagnet 14, and the arc-shaped fine-rate water-permeable net 16, effectively improving the corrosion resistance of the surfaces of the floor filtration table 1, the first filter screen 11, the circulation roller 12, the electromagnet 14, and the arc-shaped fine-rate water-permeable net 16, and extending the service life of the device.

[0044] The implementation principle of the machining process of the star wheel blade of a single-screw compressor in this embodiment is as follows: First, connect the water supply nozzle with the water supply pipe 9. Then, start the circulation pump 7 to make the filtered coolant inside 2 pass through the heat exchange tube 8 to exchange heat and cool down by using geothermal energy. Then, through the cooperation of the water supply pipe 9 and the water supply nozzle, it is directed to the surface of the star wheel blade during machining to cool the star wheel blade and wash away the debris generated during the machining of the star wheel blade surface. At the same time, the coolant carrying the debris flows through the porous support plate 5 and the water collection chamber 3 into the inside of the filtration chamber 6, and the coolant flowing into the inside of the filtration chamber 6 is preliminarily filtered by the first filter screen 11, so that the debris intercepted by the first filter screen 11 slides down under the action of gravity into the inside of the arc-shaped fine-rate water-permeable net 16 for filtration and collection. And the coolant preliminarily filtered by the first filter screen 11 flows towards the inner bottom of the filtration chamber 6 along the inclined surface of the circulation belt 15. At the same time, start the electromagnet 14 to magnetically adsorb the tiny metal debris in the coolant flowing through the surface of the circulation belt 15. Then, start the circulation motor 18 to drive the circulation roller 12 to cooperate with the arc-shaped mounting plate 13 and the electromagnet 14 to drive the circulation belt 15 to move in a cycle, and make the circulation belt 15 drive the tiny gold debris adsorbed by the electromagnet 14 to move towards the direction of the rubber scraper 17. Then, make the debris adsorbed by the electromagnet 14 on the surface of the circulation belt 15 be scraped off by the rubber scraper 17 and slide down into the inside of the arc-shaped fine-rate water-permeable net 16 under the action of gravity for filtration and collection; Then, when starting the circulation motor 18 to drive the circulation roller 12 to rotate and cooperate with the arc-shaped mounting plate 13 and the electromagnet 14 to drive the circulation belt 15 to move in a cycle, the circulation roller 12 drives the first synchronous wheel 22 to rotate. At the same time, the first synchronous wheel 22 drives the second synchronous wheel 23 to rotate by cooperating with the synchronous belt 24. By using the diameter difference between the first synchronous wheel 22 and the second synchronous wheel 23, the rotation speed of the second synchronous wheel 23 is increased. Thus, the second synchronous wheel 23 drives the hexagonal wheel 20 to rotate rapidly, and the hexagonal wheel 20 collides with the rubber contact block 21. At the same time, it pushes the rubber contact block 21 to drive the first filter screen 11 to move along the length direction of the reciprocating slide bar 10 and compress the reciprocating spring 19 to generate a contraction deformation. Then, by using the rebound characteristic of the reciprocating spring 19, the reciprocating spring 19 rebounds to push out the first filter screen 11 along the length direction of the reciprocating slide bar 10. In this way, the first filter screen 11 forms continuous vibration along the length direction of the reciprocating slide bar 10, so that the foreign matters adhered to the surface of the first filter screen 11 quickly break away and slide down into the inside of the arc-shaped fine-rate water-permeable net 16 for interception and collection; Next, when the coolant gathers into a water flow and passes through the first filter screen 11 and falls onto the top of the circulating belt 15, the coolant flows along the S-shaped drainage channels formed between the plurality of drainage plates 25, thereby effectively extending the travel of the coolant flowing through the top of the circulating belt 15, enabling the metal debris in the coolant to be more comprehensively adsorbed by the electromagnet 14. At the same time, the metal debris on the surface of the circulating belt 15 can move in the direction of the rubber squeegee 17 through the first flow groove 26 when the circulating roller 12 is started to drive the circulating belt 15 to circulate and move; Finally, when there is a large amount of debris collected inside the arc-shaped fine-rate water-permeable net 16, starting the sewage discharge motor 29 can drive the sewage auger 28 to rotate, and push the debris collected inside the arc-shaped fine-rate water-permeable net 16 to move along the length direction of the arc-shaped fine-rate water-permeable net 16 into the inside of the sewage collection box 27.
