Description

Technical Field

[0001] This invention belongs to the field of industrial waste gas recovery and utilization technology, specifically an industrial waste gas liquid recovery and utilization device. Background Technology

[0002] Industrial waste gas is a general term for gases containing pollutants generated during fuel combustion and production processes within a factory area. It is one of the main sources of air pollutants. Industrial waste gas contains volatile liquid pollutants, such as organic solvents, oil and gas, and chlorinated compounds. These volatile liquid pollutants can be recovered and reused. By separating gaseous pollutants from waste gas and converting them into liquids through physical or chemical methods, the dual goals of pollution reduction and efficiency improvement can be achieved. Its core function is to recover valuable resources and reduce the emission of waste gas pollutants. Therefore, an industrial waste gas liquid recovery and utilization device is needed.

[0003] Existing industrial waste gas liquid recovery and utilization devices typically employ condensation for recycling and reuse. This method utilizes the property that lower-temperature substances have lower saturated vapor pressure. By cooling volatile pollutants in the waste gas to below the dew point temperature, they condense from a gaseous state into a liquid state, thus achieving separation. However, when the waste gas contains solid impurities or viscous oil mist, these impurities easily adhere to the outer surface of the condenser tubes during condensation, forming a thermal resistance layer. This increases the heat exchange resistance of the condenser tubes, reducing condensation efficiency and increasing resistance to waste gas flow, leading to increased system pressure loss. Consequently, the effectiveness of the recovery and utilization device is reduced, requiring disassembly and cleaning by workers, increasing their workload and failing to meet current needs. Summary of the Invention

[0008] As a further aspect of the present invention: the recycling mechanism further includes a first cleaning component disposed in the recycling tank for cleaning the outer wall of the condenser tube. The first cleaning component includes a rotating ring rotatably disposed on a first support base and a second support base, and spiral scrapers symmetrically disposed on the rotating ring and in contact with the condenser tube.

The second support base is provided with a first guide groove for the rotation of the first guide blocks. The first transmission gear meshes with adjacent first rotating gear rings, so that the first rotating gear ring controls the rotation of the first transmission gear ring through the first transmission gear ring. The first transmission gear ring controls the rotation of a plurality of first rotating gear rings, thereby controlling the rotating ring to drive the spiral scraper to clean the condenser tube.

[0011] As a further aspect of the present invention: the first cleaning component further includes several limiting rings disposed on the two spiral scrapers. The limiting rings can improve the stability of the connection between the two spiral scrapers. Several support blocks are arranged in a circular array on the outer side of the limiting rings. At least three spiral guide fins are movably disposed between two adjacent limiting rings. The two ends of the spiral guide fins are rotatably connected to the two support blocks respectively. The fins of the spiral guide fins are inclined downward along the rotation direction of the spiral scrapers, forming a small annular airflow channel with the outer wall of the condenser tube. When the spiral guide fins rotate with the spiral scrapers, they drive the exhaust gas around the condenser tube to make a spiral swirling motion, breaking the stagnant gas layer near the tube wall, increasing the contact area and turbulence degree between the exhaust gas and the condenser tube, so that the low temperature tube wall and the high temperature exhaust gas can fully exchange heat, improve the condensation efficiency, and the swirling airflow can quickly gather the small droplets generated by condensation into large droplets, which slide down along the spiral trajectory of the spiral guide fins, avoiding the condensate from adhering and scaling on the tube wall. The spiral guide fins can also scrape off small solid impurities in the airflow, preventing them from impacting and adhering to the tube wall.

[0012] As a further aspect of the present invention: the recycling mechanism further includes a second cleaning component disposed in the recycling tank and used to clean the inner wall of the condenser tube. The second cleaning component includes a rotating rod coaxially connected to the condenser tube, a plurality of mounting parts disposed on the rotating rod, and a cleaning scraper detachably fixed to the mounting parts. A protective box is provided in the liquid outlet chamber. The top end of the rotating rod extends into the liquid inlet chamber and is rotatably connected to the inner top surface of the recycling tank. The bottom end of the rotating rod extends into the liquid outlet chamber and is rotatably connected to the upper end surface of the protective box. When the rotating rod rotates, the cleaning scraper cleans the inner wall of the condenser tube, and the cleaned impurities are discharged from the liquid outlet chamber through the coolant.

[0013] As a further aspect of the present invention: the second cleaning assembly further includes a second main gear rotatably disposed at the middle position of the protective box and a plurality of rotating gears aligned with the rotating rod. The upper ends of the second main gear and the rotating gears are each provided with a transmission block connected to the bottom end of the rotating rod. The second cleaning assembly further includes a plurality of second transmission gear rings disposed outside the second main gear and meshing externally with the rotating gears, and a second transmission gear rotatably disposed outside the rotating gears and meshing internally with the second transmission gear rings. The second transmission gear meshes with adjacent rotating gears. The bottom end of the recovery tank is provided with a second drive motor. The output shaft of the second drive motor is coaxially connected to the second main gear, so that the second main gear controls the rotation of the plurality of rotating gears. The rotating gears drive the second transmission gear rings to rotate through the second transmission gears. The second transmission gear rings drive the plurality of rotating gears to rotate. The rotating gears drive the plurality of rotating rods to rotate through the transmission blocks, so that the rotating rods control the cleaning scraper to clean the inner wall of the condenser tube. The second cleaning assembly further includes a plurality of second guide blocks arranged in a circular array on the second transmission gear rings. The protective box is provided with a second guide groove for the rotation of the second guide blocks.

[0014] As a further aspect of the present invention: the recycling mechanism further includes a cleaning component disposed at the upper end of the storage tank and used to clean the coolant entering the storage tank from the outlet chamber. The cleaning component includes a cleaning box disposed at the upper end of the storage tank and connected to the outlet pipe, and a filter screen disposed at an incline in the cleaning box. The bottom end of the cleaning box is connected to the storage tank. A first collection box is provided on one side of the cleaning box. A second collection box for collecting impurities is movably disposed in the first collection box. One end of the filter screen faces upward and extends into the first collection box, so that the coolant containing impurities is filtered through the filter screen before entering the storage tank.

[0015] As a further aspect of the present invention: the cleaning assembly further includes a synchronous belt structure symmetrically arranged inside the cleaning box and several adjusting components movably arranged on the upper end of the synchronous belt structure. The synchronous belt structure is arranged parallel to the filter screen, and two synchronous belt structures are respectively arranged on both sides of the filter screen. The inner side of the adjusting component is provided with a scraper for cleaning the filter screen through a connecting block. The scraper is made of flexible material, and the synchronous belt structure controls the movement of the scraper on the filter screen to clean the impurities adhering to the filter screen.

[0016] As a further aspect of the present invention: the cleaning assembly further includes a semi-toothed block disposed at the bottom end of the adjusting member and an adjusting rack meshing with the semi-toothed block. The adjusting rack is made of a weighting material. The semi-toothed block is provided with a rotating block rotatably connected to the synchronous belt structure, so that the adjusting member is rotatably connected to the synchronous belt structure. The bottom end of the adjusting rack is symmetrically provided with guide sliders that guide the synchronous belt structure to move. The synchronous belt structure has guide grooves that match the guide sliders. When the synchronous belt structure drives the scraper to move to the upper side of the filter screen through the adjusting member, since the synchronous belt structure is in an inclined state, the adjusting rack moves to the lower side under the action of gravity, and the adjusting rack meshes with the semi-toothed block, so that the adjusting member is rotatably connected to the synchronous belt structure. The rack and pinion drive the half-tooth block to rotate, which in turn drives the adjusting component to rotate to the higher side. This causes the adjusting component to drive the scraper to rotate. At this time, the angle between the scraper and the filter screen is acute. The scraper moves in contact with the filter screen and can stably transport the impurities removed by the filter screen. After the scraper moves upward to the first collection box, the impurities are introduced into the second collection box when the scraper separates from the filter screen. When the adjusting component drives the scraper to move downward in the first collection box, the adjusting rack moves to the lower side under the action of gravity. This causes the adjusting rack to drive the adjusting component to rotate to the higher side through the half-tooth block. The adjusting component then drives the scraper to rotate, removing the impurities from the scraper.

[0017] As a further aspect of the present invention: one end of the exhaust pipe is connected to the gas-liquid separation structure, a one-way valve is provided on the exhaust pipe, an air extraction device is provided on the outside of the gas-liquid separation structure, and an air extraction pipe connected to the exhaust pipe is provided on the air extraction device, so that the air extraction device can draw the gas in the recovery tank into the gas-liquid separation structure.

[0018] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention, through the set recycling mechanism and the first cleaning component, the exhaust gas inlet structure, the pretreatment structure, the gas-liquid separation structure, the post-treatment structure, the recycling tank, the first support base, the second support base, the condenser tube, the baffle plate, the inlet pipe and the exhaust pipe are used in combination to extend the contact time and path between the exhaust gas and the condenser tube, thereby improving the effect of recycling and reusing the exhaust gas. Through the set rotating ring, spiral scraper, connecting ring, first rotating toothed ring, first rotating external toothed ring, first main gear, first drive motor, connecting rod, first transmission toothed ring, first transmission gear and first guide block, the condenser tube can be cleaned and the cleaned impurities can be discharged through the first guide block. The liquid is discharged through the drain pipe, thus avoiding an increase in the heat exchange resistance of the condenser tube, improving the condensation effect of the condenser tube, reducing the number of maintenance operations required by staff, and improving the utilization effect of the recycling device. The limit ring, support block and spiral guide fins can increase the contact area and turbulence between the exhaust gas and the condenser tube, allowing the low temperature tube wall to fully exchange heat with the high temperature exhaust gas, improving the condensation efficiency. Moreover, the swirling airflow can quickly gather the tiny droplets generated by condensation into large droplets, which slide down along the spiral trajectory of the spiral guide fins, preventing the condensate from adhering and scaling on the tube wall, improving the cleaning efficiency of the first cleaning component, and improving the utilization effect of the recycling device.

[0019] (2) The present invention uses a second cleaning component, a rotating rod, a mounting component and a cleaning scraper to clean the inner wall of the condenser tube, preventing impurities from adhering to the inner wall of the condenser tube and improving the condensation effect of the condenser tube. The protective box, the second main gear, the rotating gear, the transmission block, the second transmission gear ring, the second transmission gear, the second drive motor and the second guide block enable several rotating rods to rotate in coordination, thereby cleaning multiple condenser tubes, improving the cleaning efficiency of the second cleaning component and improving the use effect of the recycling device.

[0020] (3) The present invention uses a cleaning component, a liquid storage tank, a liquid supply pump, an inlet pipe, an outlet pipe, a refrigeration device, and a cleaning box to make the coolant circulate. The cleaning box, filter screen, first collection box, second collection box, and synchronous belt structure can filter the circulating coolant, remove impurities from the coolant, and reduce the possibility of contamination of the condenser tube. The synchronous belt structure, adjusting component, connecting block, scraper, half-tooth block, adjusting rack, and guide slider can make the scraper clean the impurities adhering to the filter screen. The angle of the scraper can be adjusted by gravity, so that the scraper can stably transport the impurities removed by the filter screen. The scraper can also be rotated to remove impurities from the scraper, avoid secondary contamination of the filter screen, prevent impurities from falling into the liquid storage tank, improve the cleaning effect of the cleaning component, and improve the use effect of the recycling device.

[0034] Example 1 Please see Figures 1-6This application provides an industrial waste gas liquid recovery and utilization device, including a waste gas inlet structure 1 and a pretreatment structure 2 connected to the waste gas inlet structure 1. A recovery mechanism is provided on one side of the pretreatment structure 2, and a gas-liquid separation structure 3 and a post-treatment structure 4 connected to the gas-liquid separation structure 3 are connected to one side of the recovery mechanism. The recovery mechanism includes a recovery tank 5 connected to the pretreatment structure 2 and the gas-liquid separation structure 3 respectively, and a refrigeration assembly connected to the recovery tank 5. A liquid guide pump is installed between the recovery tank 5 and the gas-liquid separation structure 3. The recovery mechanism also includes a first support seat 6 located at the lower inner side of the recovery tank 5, a second support seat 7 located at the upper inner side of the recovery tank 5, and a plurality of condenser tubes 8 evenly arranged inside the recovery tank 5 and respectively installed on the first support seat 6 and the second support seat 7. The plurality of condenser tubes 8 are arranged in a circular array from the inside to the outside. The first support seat 6 and the lower inner wall of the recovery tank 5 form a liquid inlet chamber, and the second support seat 7 and the upper inner wall of the recovery tank 5 form a liquid outlet chamber. The upper and lower ends of the condenser tubes 8 are connected to the liquid inlet chamber and the liquid outlet chamber respectively, so that the refrigeration assembly... The system allows the coolant to circulate in the inlet chamber, condenser pipe 8, and outlet chamber. The recovery mechanism also includes several downward-sloping baffles 9 mounted on the inner wall of the recovery tank 5. These baffles 9 are symmetrically and staggered within the recovery tank 5, and each baffle 9 has through holes that match the condenser pipe 8, allowing them to cooperate with the recovery tank 5 to form a gas guiding channel. The recovery tank 5, first support 6, second support 7, condenser pipe 8, and baffles 9 are all made of materials resistant to exhaust gas corrosion. The recovery mechanism also includes... An air inlet pipe 10 is placed on the pretreatment structure 2 and connected to the lower part of the outer side of the recovery tank 5, and an exhaust pipe 11 is set on the upper part of the outer side of the recovery tank 5. Both the air inlet pipe 10 and the exhaust pipe 11 are aligned and connected to the air guide channel, so that the pretreatment structure 2 introduces the pre-treated waste gas into the recovery tank 5 through the air inlet pipe 10. The recovery tank 5 is provided with a drain pipe 12 for discharging the condensed liquid into the gas-liquid separation structure 3. The waste gas is condensed and recovered by the condenser pipe 8 through the air guide channel, and the gas that cannot be condensed and recovered is discharged from the exhaust pipe 11.

[0035] In this invention, the exhaust gas inlet structure 1 can be configured as an induced draft fan and an induced draft pipe connected to the induced draft fan.

The pre-treated exhaust gas is then introduced into the recovery tank 5 through the inlet pipe 10, and coolant is introduced into the recovery tank 5 through the refrigeration component. The coolant enters the condenser pipe 8 through the liquid inlet chamber and flows upward into the liquid outlet chamber. The exhaust gas flows towards the exhaust pipe 11 in the gas guide channel, which cools the target components in the exhaust gas to form condensate. The condensate flows onto the first support 6 through the baffle plate 9 and is introduced into the gas-liquid separation structure 3 through the drain pipe 12, where the gas-liquid mixture is completely separated, and the liquid coarse material is collected to prevent the liquid phase from being lost with the exhaust gas.

The air extraction device 55 is equipped with an air extraction pipe 56 that communicates with the exhaust pipe 11, so that the air extraction device 55 can extract the gas in the recovery tank 5 into the gas-liquid separation structure 3.

[0038] In this embodiment, when the exhaust efficiency in the recovery tank 5 is low, the extraction device 55 is activated, so that the exhaust pipe 11 extracts gas, and the extracted gas is introduced into the gas-liquid separation structure 3 through the extraction pipe 56.

The other end of the outlet pipe 41 is connected to the liquid storage tank 38. A refrigeration device 42 for cooling the coolant is provided on the outer side of the liquid storage tank 38, which can circulate the coolant in the liquid storage tank 38, the inlet chamber, the condenser pipe 8 and the outlet chamber.

[0040] In this embodiment, the liquid supply pump 39 is started, and the coolant in the storage tank 38 is passed through the liquid inlet pipe 40, so that the coolant enters the liquid inlet chamber and from the liquid inlet chamber enters several condenser tubes 8, thereby entering the liquid outlet chamber from the condenser tubes 8, and from the liquid outlet chamber enters the liquid outlet pipe 41, and then returns to the storage tank 38 from the liquid outlet pipe 41. The refrigeration equipment 42 is started to cool down the coolant in the storage tank 38.

The two spiral scrapers 14 are staggered. The first cleaning component also includes a connecting ring 15 disposed inside the second support 7 and connected to the upper end of the rotating ring 13, and a first rotating toothed ring 16 coaxially connected to the connecting ring 15. The first rotating toothed ring 16 is movably sleeved on the condenser tube 8 and drives the spiral scrapers 14 to rotate through the connecting ring 15 and the rotating ring 13 to clean the condenser tube 8.

[0042] In this embodiment, the first rotating toothed ring 16 is controlled to rotate, so that the first rotating toothed ring 16 drives the connecting ring 15 to rotate, the connecting ring 15 drives the rotating ring 13 to rotate, so that the rotating ring 13 drives the spiral scraper 14 to rotate, and the spiral scraper 14 cleans the condenser tube 8, and guides the cleaned impurities to the bottom of the recovery tank 5, and discharges them from the recovery tank 5 along with the condensate.

[0043] In this invention, the first cleaning component also includes a first rotating external gear ring 17 disposed in the middle of the second support 7 and a first main gear 18 for controlling the rotation of the first rotating external gear ring 17. The condenser tube 8 at the middle position passes through the first rotating external gear ring 17. The first main gear 18 meshes with the first rotating external gear ring 17. The first rotating external gear ring 17 meshes with the outer first rotating gear ring 16. The first main gear 18 and the first rotating gear ring 16 are misaligned. The top of the recovery tank 5 is provided with a first drive motor 19. The output shaft of the first drive motor 19 is provided with a connecting rod 20 that passes through the second support 7 and is coaxially connected to the first main gear 18.

[0044] In this embodiment, the first drive motor 19 is started, which drives the connecting rod 20 to rotate. The connecting rod 20 drives the first main gear 18 to rotate, and the first main gear 18 drives the first rotating external gear ring 17 to rotate, so that the first rotating external gear ring 17 drives several first rotating gear rings 16 to rotate.

[0045] In this invention, the first cleaning component further includes a first transmission gear ring 21 disposed outside the first rotating outer gear ring 17 and controlling the rotation of several first rotating gear rings 16. The first transmission gear ring 21 meshes externally with the first rotating gear rings 16. The first cleaning component also includes a first transmission gear 22 rotatably disposed in the second support 7 and meshing internally with the first transmission gear ring 21. The first transmission gear ring 21 is a double-sided gear ring. The upper ends of the first rotating gear rings 16, the first rotating outer gear ring 17, and the first transmission gear ring 21 are all arranged in a circular array with several first guide blocks 23. The second support 7 is provided with a first guide groove for the rotation of the first guide blocks 23. The first transmission gear 22 meshes with the adjacent first rotating gear rings 16, so that the first rotating gear rings 16 control the rotation of the first transmission gear ring 21 through the first transmission gear 22. The first transmission gear ring 21 controls the rotation of several first rotating gear rings 16, thereby controlling the rotating ring 13 to drive the spiral scraper 14 to clean the condenser tube 8.

[0046] In this embodiment, the first drive motor 19 is started, causing the first main gear 18 to drive the first rotating gear ring 16 to rotate via the first rotating external gear ring 17. The first rotating gear ring 16 drives the first transmission gear 22 to rotate, which in turn drives the first transmission gear ring 21 to rotate. The first transmission gear ring 21 drives several first rotating gear rings 16 to rotate, thus performing sequential transmission. This allows the first rotating gear ring 16 to drive the spiral scraper 14 to clean the condenser tube 8 via the rotating ring 13.

[0047] The first cleaning component of this invention also includes several limiting rings 24 disposed on the two spiral scrapers 14. The limiting rings 24 can improve the stability of the connection between the two spiral scrapers 14. Several support blocks 25 are arranged in a circular array on the outer side of the limiting rings 24. At least three spiral guide fins 26 are movably disposed between two adjacent limiting rings 24. The two ends of the spiral guide fins 26 are respectively rotatably connected to the two support blocks 25. The fins of the spiral guide fins 26 are inclined downward along the rotation direction of the spiral scrapers 14, forming a small annular airflow channel with the outer wall of the condenser tube 8. When the spiral guide fins 26 rotate with the spiral scraper 14, they drive the exhaust gas around the condenser tube 8 to make a spiral swirling motion, breaking the stagnant gas layer near the tube wall, increasing the contact area and turbulence between the exhaust gas and the condenser tube 8, so that the low-temperature tube wall and the high-temperature exhaust gas can fully exchange heat, improve the condensation efficiency, and the swirling airflow can quickly gather the tiny droplets generated by condensation into large droplets, which slide down along the spiral trajectory of the spiral guide fins 26, avoiding the condensate from adhering and scaling on the tube wall. In addition, the spiral guide fins 26 can scrape off tiny solid impurities in the airflow, preventing them from impacting and adhering to the tube wall.

[0048] In this embodiment, when the spiral scraper 14 rotates, it causes the limiting ring 24 to rotate, which in turn causes the support block 25 to rotate. This causes the support block 25 to rotate the spiral guide fins 26 around the condenser tube 8. When the spiral guide fins 26 rotate and are subjected to external force, they rotate on the support block 25, thereby forming a small annular airflow channel with the outer wall of the condenser tube 8, which in turn causes the exhaust gas around the condenser tube 8 to undergo a spiral swirling motion.

In this embodiment, the recycling mechanism further includes a second cleaning component disposed in the recycling tank 5 and used to clean the inner wall of the condenser tube 8.

When the rotating rod 27 rotates, the cleaning scraper 29 cleans the inner wall of the condenser tube 8, and the cleaned impurities are discharged from the liquid outlet chamber through the coolant.

[0050] In this embodiment, the rotating rod 27 is controlled to rotate, which causes the mounting part 28 to rotate, which in turn causes the cleaning scraper 29 to rotate. The cleaning scraper 29 cleans the protective box 30, and the removed impurities are discharged from the outlet chamber through the coolant.

[0051] The second cleaning component of this invention further includes a second main gear 31 rotatably disposed at the middle position of the protective box 30 and several rotating gears 32 aligned with the rotating rod 27.

The output shaft of the machine 36 is coaxially connected to the second main gear 31, so that the second main gear 31 controls several rotating gears 32 to rotate. The rotating gears 32 drive the second transmission gear ring 34 to rotate through the second transmission gear 35. The second transmission gear ring 34 drives several rotating gears 32 to rotate. The rotating gears 32 drive several rotating rods 27 to rotate through the transmission block 33, so that the rotating rods 27 control the cleaning scraper 29 to clean the inner wall of the condenser tube 8. The second cleaning component also includes several second guide blocks 37 arranged in a circular array on the second transmission gear ring 34. The protective box 30 is provided with a second guide groove for the rotation of the second guide blocks 37.

The rotating gears 32 drive the second transmission gear 35 to rotate, which in turn drives the second transmission gear ring 34 to rotate. The second transmission gear ring 34 drives several rotating gears 32 to rotate, and the rotation of the second transmission gear ring 34 drives the second guide block 37 to rotate in the second guide groove. This causes the rotating gears 32 to drive the transmission block 33 to rotate, and the transmission block 33 drives the rotating rod 27 to rotate. The rotating rod 27 drives the cleaning scraper 29 to clean the protective box 30 through the mounting part 28.

[0053] Example 3 Based on Example 2, referring to Figure 1 and Figures 9-11 This is the third embodiment of the present invention. In this embodiment, the recovery mechanism further includes a cleaning component disposed on the upper end of the storage tank 38 to clean the coolant entering the storage tank 38 from the outlet chamber. The cleaning component includes a cleaning box 43 disposed on the upper end of the storage tank 38 and connected to the outlet pipe 41, and a filter screen 44 disposed at an incline in the cleaning box 43. The bottom end of the cleaning box 43 is connected to the storage tank 38. A first collection box 45 is provided on one side of the cleaning box 43. A second collection box 53 for collecting impurities is movably disposed in the first collection box 45. One end of the filter screen 44 faces upward and extends into the first collection box 45, so that the coolant containing impurities is filtered through the filter screen 44 before entering the storage tank 38.

[0054] In this embodiment, the liquid supply pump 39 is started, so that the coolant circulates in the liquid storage tank 38, the liquid inlet pipe 40, the liquid inlet chamber, the condenser pipe 8, the liquid outlet chamber and the liquid outlet pipe 41. When the coolant enters the cleaning box 43 through the liquid outlet pipe 41, the filter screen 44 filters the impurities in the coolant and introduces the filtered coolant into the liquid storage tank 38.

[0055] The cleaning component of this invention also includes a synchronous belt structure 46 symmetrically arranged inside the cleaning box 43 and several adjusting members 47 movably arranged on the upper end of the synchronous belt structure 46. The synchronous belt structure 46 is arranged parallel to the filter screen 44, and the two synchronous belt structures 46 are respectively arranged on both sides of the filter screen 44. The inner side of the adjusting member 47 is provided with a scraper 49 for cleaning the filter screen 44 through a connecting block 48. The scraper 49 is made of flexible material. The synchronous belt structure 46 controls the scraper 49 to move on the filter screen 44 to clean the impurities adhering to the filter screen 44.

[0056] In this embodiment, when the coolant enters the cleaning box 43 through the outlet pipe 41, the filter screen 44 filters the impurities in the coolant. The synchronous belt structure 46 is activated, which drives the adjusting member 47 to move. The adjusting member 47 drives the connecting block 48 to move, and the connecting block 48 drives the scraper 49 to move. The scraper 49 cleans the impurities on the filter screen 44 and transports the cleaned impurities to the first collection box 45, and then into the second collection box 53. The second collection box 53 is disassembled and cleaned every once in a while.

[0057] The cleaning component of the present invention also includes a half-tooth block 50 disposed at the bottom end of the adjusting member 47 and an adjusting rack 51 meshing with the half-tooth block 50. The adjusting rack 51 is made of a weighting material. The half-tooth block 50 is provided with a rotating block that is rotatably connected to the synchronous belt structure 46, so that the adjusting member 47 is rotatably connected to the synchronous belt structure 46. The bottom end of the adjusting rack 51 is symmetrically provided with guide sliders 52 that guide the synchronous belt structure 46 to move. The synchronous belt structure 46 is provided with guide grooves that match the guide sliders 52.

[0058] In this embodiment, when the synchronous belt structure 46 moves the scraper 49 to the upper side of the filter screen 44 via the adjusting member 47, the adjusting rack 51 moves to the lower side under the action of gravity because the synchronous belt structure 46 is in an inclined state. The adjusting rack 51 meshes with the half-tooth block 50, causing the adjusting rack 51 to drive the half-tooth block 50 to rotate. The half-tooth block 50 drives the adjusting member 47 to rotate to the higher side, causing the adjusting member 47 to drive the scraper 49 to rotate. At this time, the angle between the scraper 49 and the filter screen 44 is an acute angle, and the scraper 49 adheres to the filter screen 44. When the scraper 49 moves upward, it can stably transport the impurities removed by the filter screen 44. After the scraper 49 moves upward to the first collection box 45, when the scraper 49 separates from the filter screen 44, the removed impurities are introduced into the second collection box 53. When the adjusting member 47 drives the scraper 49 to move downward in the first collection box 45, the adjusting rack 51 moves to the lower side under the action of gravity, so that the adjusting rack 51 drives the adjusting member 47 to rotate to the higher side through the half-tooth block 50. The adjusting member 47 drives the scraper 49 to rotate, removing the impurities on the scraper 49.
