Description

Technical Field

[0001] The invention relates to the technical field of liquid filtration, and in particular to a filtration device and method based on the recovery and treatment of coolant from an automobile lamp injection mold. Background Art

[0002] In the automotive manufacturing industry, injection molds are key equipment for producing plastic parts such as headlights. Injection molds generate a lot of heat during operation. In order to maintain the normal operation of the mold and extend its service life, coolant is required for cooling. However, various impurities such as metal debris, plastic particles, dust, etc. will be mixed into the coolant during the circulation process. If these impurities are not removed in time, it will not only affect the cooling effect of the coolant, but also may cause damage to the mold and injection molding machine. Especially for automobile headlight injection molds, due to its extremely high requirements for product quality and appearance, it also has higher requirements for the quality and cleanliness of the coolant.

[0003] For example, the patent application with the prior art announcement number CN213760689U relates to the technical field of machine tool processing and discloses a machine tool coolant filter device, which solves the problem that during the process of cleaning iron chips in the existing machine tool coolant filter device, iron chips may fall into the coolant recovery box, resulting in low coolant filtration efficiency. The coolant filter device includes a coolant recovery box, which is arranged below the machining tool, and the upper surface of the coolant recovery box is opened. Both outer side walls of the coolant recovery box are opened with plug-in grooves, and also includes a filtering mechanism, the filtering mechanism includes a first filter plate and a second filter plate arranged up and down, the first filter plate is plugged into the corresponding plug-in groove and enters the coolant recovery box, and the second filter plate is plugged into the corresponding plug-in groove at one end close to the coolant recovery box, and the projections of the first filter plate and the second filter plate in the horizontal direction always overlap, thereby improving the coolant filtration efficiency and reducing the phenomenon of iron chips falling into the coolant recovery box.

[0004] The above-mentioned prior art can indeed filter the coolant by setting a filtering mechanism, and effectively remove impurities such as iron filings mixed therein. However, in the actual production operation scenario, when the coolant completes the cooling task of the injection mold, it will absorb a large amount of heat emitted by the mold, causing its own temperature to rise significantly. For example, in a high-speed, continuous injection molding production process, the temperature of the coolant may rise by 15-25°C when it flows out of the mold. At this time, if only relying on existing physical filtering means, such as simple filter filtration or filter element filtration, it can only solve the problem of solid impurities in the coolant, and it has no effect on reducing its increased temperature. On the one hand, the coolant with too high a temperature will affect the performance of the filter medium in the subsequent filtration link and shorten its service life; on the other hand, if it is directly injected back into the mold, it cannot meet the strict requirements of the mold for the cooling temperature, seriously affecting the cooling effect of the mold, thereby reducing the quality and molding accuracy of the injection molded product, and greatly hindering the efficient reuse of the coolant. To this end, the present application proposes a filtering device and method based on the recovery and treatment of the coolant of the automobile headlight injection mold. Summary of the invention

[0008] Preferably, the self-rotating component includes a ventilation plate fixedly connected to the inside of the air duct and supporting the rotation of the connecting rod, and a plurality of through holes for gas to pass through are opened inside the ventilation plate, piston plates are arranged in the plurality of through holes, and connecting handles are fixedly connected to the tops of the plurality of piston plates, and the plurality of connecting handles are commonly fixedly connected to a common connecting ring sleeved on the outer surface of the connecting rod, the outer surface of the connecting rod is evenly fixedly connected to a plurality of oblique bars, and a plurality of arc plates are fixedly connected to the outer surface of the connecting rod located above the plurality of oblique bars, and a plurality of balls that interfere with the oblique bars are rotatably connected to the top of the common connecting ring.

[0009] Preferably, a liquid storage chamber for storing additives is provided inside the air duct, and the outer surface of the liquid storage chamber is connected to a plurality of liquid pipes, the tops of the plurality of piston plates are hinged with cranks, the interior of the liquid storage chamber is slidably connected with a plurality of sliding rods rotatably connected to the cranks, the interior of the liquid storage chamber is fixedly connected with a plurality of supporting members, and the bottoms of the plurality of supporting members are rotatably connected with a blocking plate that can block the liquid pipe, and the sliding rod can interfere with one end of the blocking plate.

[0010] Preferably, the outer surface of the connecting rod is fixedly connected to a sleeve frame mounted on the outer surface of the air duct, and a plurality of arc-shaped plates are fixedly connected to the interior of the sleeve frame. The top of the liquid pipe is slidably connected to a pressure piston rod adapted thereto, and the top of the pressure piston rod is fixedly connected to a compression spring fixedly connected to the air duct, and the arc-shaped plates are in contact with the bottoms of the plurality of pressure piston rods.

[0012] Preferably, a plurality of slide seats for supporting the transmission roller are slidably connected to the top of the output shaft, a spring is fixedly connected to the top of the output shaft, and the spring is fixedly connected to the plurality of slide seats respectively.

[0013] Preferably, one side of the filter tank is connected to a liquid injection port, one end of the spiral liquid inlet pipe extends to the inside of the liquid injection port, the bottom of the filter tank is connected to a liquid outlet pipe, and the filter cartridge is fixedly connected to the top of the liquid outlet pipe.

[0014] Preferably, the top of the filter tank is provided with an exhaust port for gas discharge.

[0015] The present invention also provides a filtering method based on the recovery and treatment of the coolant of the automobile lamp injection mold, comprising the following steps: S1. When in use, first pour the coolant to be recycled into the filter tank. The coolant will enter the filter tank through the spiral inlet pipe and pass through the filter screen for preliminary filtration, and then pass through the filter cartridge for fine treatment; S2, then start the driving assembly to rotate the multiple blades to extract air from the inside of the air inlet pipe, and the gas passes through the spiral liquid inlet pipe to dissipate the heat of the coolant inside and then is discharged; S3. When the gas passes through the spiral liquid inlet pipe, it will drive the self-rotating component to run, thereby driving the connecting rod to rotate, driving the collection plate to clean the filter, and at the same time mixing the additive with the coolant to improve its heat dissipation performance; S4. When the driving component is running, it also drives the transmission component to run and drive the rotating plate to flip to achieve liquid discharge.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The output shaft is driven by the driving motor, and the blades rotate at high speed through the cooperation of the transmission roller and the rotating roller, and the air is sucked from the air intake pipe and discharged through the air duct. The airflow passes accurately through the center of the spiral inlet pipe. This design increases the contact area and time between the coolant and the airflow, greatly improving the heat dissipation efficiency. The setting of multiple rotating plates and related transmission components realizes the precise control of the coolant flow rate. When the output shaft rotates, under the synergistic effect of centrifugal force and spring, the contacting inclined block intermittently contacts the rotating handle, causing the rotating plate to flip, thereby controlling the amount of coolant discharged. This precise flow regulation avoids the problem of insufficient filtration caused by excessive coolant flow, ensures that the coolant has enough time for fine filtration in the filter cartridge, and improves the filtration quality.

[0017] As the preliminary filtering link before the filter cartridge, the filter can effectively intercept larger particles of impurities in the coolant, such as plastic debris and metal particles, greatly reducing the filtering burden of the filter cartridge. This not only extends the service life of the filter cartridge, but also ensures the effect of subsequent fine filtering and improves the overall purity of the coolant. The combination of the collection plate and the self-rotating component realizes the automation of impurity cleaning. The self-rotating component uses the airflow generated by the blades as power to drive the collection plate to rotate slowly. During the rotation process, the collection plate can collect the impurities blocked by the filter screen in a centralized manner to prevent the impurities from accumulating on the surface of the filter screen and affecting the filtering efficiency. The power of the self-rotating component comes from the airflow generated by the blades, which means that while the collection plate rotates to clean the impurities, no additional energy is consumed. Moreover, when the piston plate is impacted by the airflow and moves upward, it not only drives the rotation of the collection plate, but also triggers the additive addition mechanism. This automatic cleaning mechanism matches the continuous operation characteristics of the original device, ensuring the continuity and stability of the filtering process. The additive addition structure is closely connected with the rotation of the connecting rod. When the piston plate moves upward, it drives the crank to tilt and push the slide rod, thereby opening the channel between the liquid storage chamber and the liquid pipe, so that the additive enters the filter tank and mixes with the coolant. At the same time, the connecting rod drives the sleeve to rotate, and the arc-shaped sheet and the pressure piston rod cooperate to achieve precise control of the amount of additive added and the flow rate. The double barrier formed by the plugging plate and the pressure piston rod ensures that the additive enters the coolant at the right time and flow rate, which not only avoids the waste of additives, but also ensures that it can effectively play the role of enhancing heat conduction.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 , Figure 2 as well as Figure 3The present invention provides a technical solution: a filtering device based on the recovery and treatment of coolant of an automobile lamp injection mold, comprising a filter tank 100 and a filter cartridge 105 arranged inside the filter tank 100 and used for filtering coolant, one side of the filter tank 100 is connected with a liquid injection port 101, one end of a spiral liquid inlet pipe 200 extends to the inside of the liquid injection port 101, the bottom of the filter tank 100 is connected with a liquid outlet pipe 104, the filter cartridge 105 is fixedly connected to the top of the liquid outlet pipe 104, and the top of the filter tank 100 is provided with an exhaust port 103 for gas discharge, by arranging the filter cartridge 105, the coolant can be filtered to improve the reuse of the coolant, and only the coolant filtered by the filter cartridge 105 will be discharged through the liquid outlet pipe 104, and by arranging the air inlet pipe 102, the air in the filter tank 100 can be guided and cooperated with the exhaust port 103 to form a flowing gas.

[0022] See also Figure 2 , Figure 4 as well as Fig.12 , further comprising a spiral liquid inlet pipe 200, which is vertically arranged inside the filter tank 100 and is used to transport coolant, a plurality of blades 202 for blowing air to the spiral liquid inlet pipe 200 are arranged inside the filter tank 100, the bottom of the filter tank 100 is connected to an air inlet pipe 102 for gas to enter, and a driving assembly for driving the plurality of blades 202 to rotate is arranged inside the filter tank 100, the driving assembly comprises a driving motor 204 fixedly connected to the inside of the filter tank 100, a wind guide pipe 201 fixedly connected to the top of the air inlet pipe 102 and communicating with the inside thereof, and an output end of the driving motor 204 is fixedly connected to An output shaft 205 is connected, and a plurality of transmission rollers 208 are arranged on the top of the output shaft 205. The inside of the air guide duct 201 is rotatably connected to a rotating rod 207 for supporting a plurality of blades 202. The bottom of the rotating rod 207 is fixedly connected to a rotating roller 206 adapted to the plurality of transmission rollers 208. The flow path of the coolant can be increased by arranging a spiral liquid inlet pipe 200, so that the gas generated by the blades 202 can pass through the center of the spiral liquid inlet pipe 200 to drive the heat in the coolant, thereby realizing the heat dissipation of the coolant, wherein the transmission roller 208 and the rotating roller 206 are arranged to realize transmission.

[0023] See also Figure 3 , Fig.13 as well as Fig.14, and further includes a rotating sheet 400, which is provided in plurality and connected to the inside of the filter tank 100 for controlling the amount of coolant passing through, and a transmission assembly for driving the plurality of rotating sheets 400 to turn over alternately is provided in the inside of the filter tank 100, and the transmission assembly includes a plurality of rotating handles 401 rotatably connected to the inside of the air guide 201, and one end of the plurality of rotating handles 401 is fixedly connected to the plurality of rotating sheets 400, and a plurality of extension plates 404 are provided above the output shaft 205, and the ends of the plurality of extension plates 404 that are away from each other are fixedly connected with a plurality of rotating handles 401 that can contact with the plurality of rotating handles 401. The inclined block 405 and the plurality of rotating sheets 400 can control the amount of coolant passing through, reduce the pressure between the coolants, and thus reduce the filtering load of the exhaust port 103, so that the coolant can be fully filtered. The extension plate 404 and the inclined block 405 can be arranged to contact the handle 401 when the output shaft 205 rotates, so that the rotating sheet 400 can be turned over to allow the coolant to pass through. At the same time, a torsion spring is arranged at the connection of the handle 401 for its own reset, so that the rotating sheet 400 will be turned over and opened to allow the coolant to pass through only when the inclined block 405 contacts the handle 401.

[0024] Among them, the top of the output shaft 205 is slidably connected with multiple slides 402 for supporting the transmission roller 208, the top of the output shaft 205 is fixedly connected with a spring 403, and the spring 403 is respectively fixedly connected to the multiple slides 402, and the driving motor 204 is in a continuously turned-on state to make the output shaft 205 rotate continuously. Under the action of centrifugal force, the transmission roller 208 will be disconnected from the rotating roller 206 and push the abutting inclined block 405 to approach the rotating handle 401, thereby abutting the rotating handle 401. When the abutting inclined block 405 abuts the rotating handle 401, due to the influence of the inclined surface on one side of the abutting inclined block 405 and the action of the spring 403, the transmission roller 208 approaches the rotating roller 206 again, thereby realizing the alternating rotation of the transmission rotating roller 206 and the pushing of the rotating handle 401.

[0025] Specifically, the drive motor 204 is turned on immediately to drive the output shaft 205 to rotate, thereby driving the multiple transmission rollers 208 to rotate along with it and drive the rotating roller 206 to rotate, so that the multiple blades 202 rotate and extract air from the inside of the air inlet pipe 102 and discharge it through the air duct 201. The gas passes through the spiral liquid inlet pipe 200 to dissipate the coolant inside. When the output shaft 205 continues to rotate, a certain centrifugal force will be generated to act on the transmission roller 208, thereby driving the slide 402 to squeeze the spring 403 and move, which makes the transmission roller 208 and the rotating roller 206 disengage from the conflict and unable to drive the blades 202 to rotate and generate airflow. At the same time, when the slide 402 is misplaced, it will drive the conflicting inclined block 405 to conflict with the multiple rotating handles 401, thereby driving them to rotate and drive the rotating sheet 400 to flip and realize liquid discharge. When the conflicting inclined block 405 conflicts with the rotating handle 401, it will be pushed to suppress the centrifugal force and thus conflict with the rotating roller 206 again, thereby controlling the gradual change of the airflow intensity in the air duct 201.

[0026] In summary, the output shaft 205 is driven by the driving motor 204, and the blades 202 are rotated at high speed through the cooperation of the transmission roller 208 and the rotating roller 206, and the air is sucked from the air inlet pipe 102 and discharged through the air guide pipe 201, and the air flow accurately passes through the center of the spiral liquid inlet pipe 200. This design increases the contact area and time between the coolant and the air flow, greatly improves the heat dissipation efficiency, and the arrangement of multiple rotating plates 400 and related transmission components realizes the precise control of the amount of coolant passing through. When the output shaft 205 rotates, under the synergistic effect of centrifugal force and spring 403, the contacting inclined block 405 intermittently contacts the rotating handle 401, causing the rotating plate 400 to flip, thereby controlling the amount of coolant discharged. This precise flow regulation avoids the problem of insufficient filtration caused by excessive coolant flow, ensures that the coolant has enough time to be finely filtered in the filter cartridge 105, and improves the filtration quality.

[0027] Example 2: Please refer to Figure 5 , Figure 6 as well as Figure 7 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: the filtering device based on the recovery and treatment of the coolant of the automobile lamp injection mold also includes a filter 300, which is fixedly connected to the inside of the filter tank 100 for filtering impurities in the coolant, and a collection plate 301 for collecting impurities is arranged above the filter 300, and a connecting rod 302 for supporting the collection plate 301 is arranged inside the filter tank 100. A self-rotating component for driving the collection plate 301 to rotate is arranged inside the filter tank 100, and the power of the self-rotating component comes from the airflow generated by the blade 202. By setting the filter 300, the coolant can be preliminarily filtered before the filter cartridge 105 filters the coolant, so as to remove impurities on its surface, and the collection plate 301 can be arranged to facilitate the collection of impurities blocked by the filter 300, and the self-rotating component can drive the collection plate 301 to rotate slowly to clean the filter 300. See also Figure 7 , Figure 8 as well as Fig. 9Furthermore, the self-rotating component includes a vent plate 203 fixedly connected to the inside of the air duct 201 and supporting the rotation of the connecting rod 302, and the inside of the vent plate 203 is provided with a plurality of through holes for gas to pass through, a piston plate 303 is arranged in each of the plurality of through holes, and a connecting handle 304 is fixedly connected to the top of each of the plurality of piston plates 303, and the plurality of connecting handles 304 are commonly fixedly connected to a common sleeve ring 305 sleeved on the outer surface of the connecting rod 302, the outer surface of the connecting rod 302 is uniformly fixedly connected to a plurality of inclined strips 306, and the outer surface of the connecting rod 302 is located above the plurality of inclined strips 306 and is fixedly connected to a plurality of arc plates 307, the common sleeve The top of the ring 305 is rotatably connected to a plurality of balls 308 that are in contact with the oblique bars 306. By setting up a self-rotating component, power can be generated by relying on the flow of gas to drive the collecting plate 301 to rotate. When the piston plate 303 is impacted by strong gas, it will move upward and drive the joint ring 305 to move upward on the surface of the connecting rod 302, which makes the balls 308 contact with the arc plate 307 and push the connecting rod 302 to rotate. Then the balls 308 will be located above the oblique bars 306. As the gas impact force decreases, the filter screen 300 will move downward and drive the balls 308 to slide on the top of the oblique bars 306, thereby driving the connecting rod 302 to rotate.

[0028] See also Fig. 9 , Fig.10 as well as Fig.11A liquid storage chamber 313 for storing additives is provided inside the air duct 201, and the outer surface of the liquid storage chamber 313 is connected to a plurality of liquid pipes 314, the tops of the plurality of piston plates 303 are hinged with cranks 310, the inside of the liquid storage chamber 313 is slidably connected with a plurality of slide bars 309 rotatably connected with the cranks 310, the inside of the liquid storage chamber 313 is fixedly connected with a plurality of support members 311, and the bottoms of the plurality of support members 311 are rotatably connected with a blocking plate 312 that can block the liquid pipe 314, the slide bar 309 can abut against one end of the blocking plate 312, the outer surface of the connecting rod 302 is fixedly connected with a sleeve frame 318 sleeved on the outer surface of the air duct 201, the inside of the sleeve frame 318 is fixedly connected with a plurality of arc-shaped sheets 316, the top of the liquid pipe 314 is slidably connected with An adapted pressure piston rod 315, the top of which is fixedly connected with a compression spring 317 fixedly connected to the air duct 201, and the arc-shaped piece 316 abuts against the bottom of multiple pressure piston rods 315. At the same time, when the piston plate 303 is forced to move upward, it will drive the crank 310 to tilt and push the slide rod 309 to move. At the same time, a torsion spring is provided at the connection between the crank 310 and the piston plate 303, and the torsion spring can drive the piston plate 303 to reset and fit on the ventilation plate 203. As the slide rod 309 moves, it will abut against the blocking plate 312 and drive the channel between the liquid storage chamber 313 and the liquid pipe 314, so that the additive in the liquid storage chamber 313 enters the interior of the filter tank 100 and mixes with the coolant. The additive can be nano-aluminum oxide, nano-copper oxide, nano-titanium dioxide, etc. These nanoparticles have a very large specific surface area and can effectively enhance the heat conduction capacity of the coolant. At the same time, when the arc-shaped sheet 316 does not conflict with the pressure piston rod 315, the pressure piston rod 315 will block the liquid pipe 314 under the action of the compression spring 317, and cooperate with the blocking plate 312 to form two barriers to prevent the leakage of additives in the liquid storage chamber 313. When the pressure piston rod 315 is pulled up, the liquid pipe 314 is opened and when it moves down and resets, the flow efficiency of the additive in the liquid pipe 314 is accelerated, thereby improving the smoothness of circulation.

[0029] Specifically, when the gas passes through the air duct 201, it will first pass through the ventilation plate 203. At this time, the impact of the gas will drive the multiple piston plates 303 to move upward and then drive the common ring 305 to move along with it, so that the ball 308 and the arc plate 307 collide, thereby driving the connecting rod 302 to rotate. When a small amount of gas passes through the piston plate 303, the common ring 305 moves downward and drives the ball 308 to collide with the inclined bar 306, thereby driving the connecting rod 302 to rotate. At the same time, during the upward movement of the piston plate 303, one end of the crank 310 is driven to move, so that the sliding rod 309 is pushed, and then it collided with one end of the blocking plate 312, so that the liquid storage chamber 313 and the liquid pipe 314 are connected. The additive in the liquid storage chamber 313 is connected. Under the action of hydraulic pressure, the additive is discharged to the inside of the filter tank 100 through the liquid pipe 314 to mix with the coolant. At the same time, when the connecting rod 302 rotates, the collecting plate 301 will be driven to rotate together. At the same time, the connecting rod 302 drives the sleeve 318 to rotate and drives the arc-shaped piece 316 to move, thereby pulling one end of the pressure piston rod 315 to move upward, so that the movement of the blocking plate 312 is synchronized with the movement of the pressure piston rod 315, so that the additive can pass through the liquid pipe 314 smoothly. At the same time, when the arc-shaped piece 316 and the pressure piston rod 315 are out of contact, the pressure piston rod 315 will move downward under the action of the compression spring 317 to squeeze the additive in the liquid pipe 314.

[0030] In summary, the filter screen 300, as a preliminary filtering link before the filter cartridge 105, can effectively intercept larger particles of impurities in the coolant, such as plastic debris, metal particles, etc., greatly reducing the filtering burden of the filter cartridge 105. This not only extends the service life of the filter cartridge 105, but also ensures the effect of subsequent fine filtration, improves the overall purity of the coolant, and the combination of the collection plate 301 and the self-rotating component realizes the automation of impurity cleaning. The self-rotating component uses the airflow generated by the blades 202 as power to drive the collection plate 301 to rotate slowly. During the rotation process, the collection plate 301 can collect the impurities blocked by the filter screen 300 to prevent the impurities from accumulating on the surface of the filter screen 300 and affecting the filtering efficiency. The power of the self-rotating assembly comes from the airflow generated by the blades 202, which means that while the collection plate 301 rotates to clean impurities, no additional energy is consumed. Moreover, when the piston plate 303 moves upward due to the impact of the airflow, it not only drives the collection plate 301 to rotate, but also triggers the additive adding mechanism. This automatic cleaning mechanism matches the continuous operation characteristics of the original device, ensuring the continuity and stability of the filtering process. The additive adding structure is closely connected with the rotation of the connecting rod 302. When the piston plate 303 moves upward, it drives the crank 310 to tilt and push the slide bar 309, thereby opening the channel between the liquid storage chamber 313 and the liquid pipe 314, so that the additive enters the filter tank 100 and mixes with the coolant. At the same time, the connecting rod 302 drives the sleeve 318 to rotate, and through the cooperation of the arc-shaped plate 316 and the pressure piston rod 315, the precise control of the additive addition amount and flow rate is achieved. The double barrier formed by the blocking plate 312 and the pressure piston rod 315 ensures that the additive enters the coolant at the right time and flow rate, which not only avoids the waste of additives, but also ensures that it can effectively play the role of enhancing heat conduction.

[0031] Example 3: Please refer to Figures 1 to 14 The present invention also provides a technical solution, which is different from the technical solution of the first embodiment: a filtering method based on the recovery and treatment of the coolant of the automobile lamp injection mold, comprising the following steps: S1. When in use, the coolant to be recycled is first poured into the filter tank 100 through the liquid injection port 101. The coolant enters the filter tank 100 through the spiral liquid inlet pipe 200 and is initially filtered through the filter screen 300. Then, it is finely treated through the filter cartridge 105 and discharged through the liquid outlet pipe 104. S2, the driving motor 204 is then turned on to drive the output shaft 205 to rotate, thereby driving the multiple transmission rollers 208 to rotate together with it and drive the rotating roller 206 to rotate, so that the multiple blades 202 rotate to extract air from the inside of the air inlet pipe 102 and discharge it through the air guide pipe 201, and the gas passes between the spiral liquid inlet pipe 200 to dissipate the heat of the coolant inside it; S3. When the gas passes through the air duct 201, it will first pass through the ventilation plate 203. At this time, the impact of the gas will drive the multiple piston plates 303 to move upward and then drive the common ring 305 to move with it, so that the ball 308 and the arc plate 307 collide, thereby driving the connecting rod 302 to rotate. When a small amount of gas passes through the piston plate 303, the common ring 305 moves downward and drives the ball 308 to collide with the inclined bar 306, thereby driving the connecting rod 302 to rotate. At the same time, during the upward movement of the piston plate 303, one end of the crank 310 will be driven to move, so that the sliding rod 309 is pushed, and then it collided with one end of the blocking plate 312, so that the liquid storage chamber 313 and the liquid pipe 314 are closed. The additive in the liquid storage chamber 313 is connected. Under the action of hydraulic pressure, the additive is discharged to the inside of the filter tank 100 through the liquid pipe 314 to mix with the coolant. At the same time, when the connecting rod 302 rotates, it will drive the collecting plate 301 to rotate together. At the same time, the connecting rod 302 drives the sleeve 318 to rotate and drives the arc-shaped piece 316 to move, thereby pulling one end of the pressure piston rod 315 to move upward, so that the movement of the blocking plate 312 is synchronized with the movement of the pressure piston rod 315, which is convenient for the additive to pass through the liquid pipe 314 smoothly. At the same time, when the arc-shaped piece 316 and the pressure piston rod 315 are out of conflict, the pressure piston rod 315 will move downward under the action of the compression spring 317 to squeeze the additive in the liquid pipe 314; S4. When the output shaft 205 rotates continuously, a certain centrifugal force will be generated on the transmission roller 208, thereby driving the slide 402 to squeeze the spring 403 and move, which makes the transmission roller 208 disengage from the rotating roller 206 and unable to transmit the blade 202 to rotate and generate airflow. At the same time, when the slide 402 is misplaced, it will drive the conflicting inclined block 405 to conflict with multiple rotating handles 401, thereby driving them to rotate and drive the rotating plate 400 to flip and realize liquid discharge. When the conflicting inclined block 405 conflicts with the rotating handle 401, it will be pushed to suppress the centrifugal force and thus conflict with the rotating roller 206 again, thereby controlling the gradual change of the airflow intensity in the air duct 201, thereby realizing the up and down movement of the piston plate 303.
