[0015] This invention provides a circulating water system for chemical production, which has the following beneficial effects: 1. This invention uses a dual-axis motor to drive the filter assembly to rotate, allowing each part to alternately contact wastewater, thus improving the utilization rate of consumables. The large-size design of the filter assembly provides a high dirt-holding capacity, extends the maintenance cycle, and reduces long-term operating costs. During the filtration process, the diaphragm inside the fixed cylinder can vibrate and automatically draw in wastewater, eliminating the need for an independent water pump system, saving costs and space. In addition, the diaphragm is made of corrosion-resistant fluororubber, which has higher corrosion resistance to waste liquid containing impurities compared to existing water pumps. It also prevents the high-speed rotating blades from colliding with impurity particles, thus preventing aggravated wear and improving the service life and reliability of the equipment.

[0016] 2. This invention uses diaphragm vibration to cause air pressure changes, driving airflow to backflush the filter screen, automatically clearing blockages and impurities, avoiding downtime for maintenance. Subsequently, the airflow carrying impurities enters the waste bin for centralized treatment through the collection pipe, and the exhaust gas is purified by the activated carbon filter plate to prevent pollution. When the filter screen rotates, the collection pipe is vibrated by a protrusion and baffle mechanism to shake off impurities from the inner wall, ensuring smooth collection of impurities. During this process, the filtrate screen discharges excess waste liquid, and the corrugated sealing sleeve allows vibration while sealing, ensuring the normal operation of the unblocking function.

[0017] 3. This invention is equipped with a liquid level protection mechanism. When the filtration rate is insufficient and the liquid level rises, the float will cut off the transmission through mechanical linkage, thereby fundamentally preventing wastewater overflow. This purely mechanical design does not rely on the electrical system, has a reliable response, provides maintenance buffer for staff, and will automatically resume transmission when the liquid level drops, without manual intervention, simplifying the restart process and improving the automation level of the equipment.

[0020] Please see Figures 1 to 4This invention provides a technical solution: a chemical production circulating water system, comprising a tank 1 and a drive assembly 3. A filter assembly 2 is rotatably connected inside the tank 1. The filter assembly 2 includes a filter screen 201. The filter screen 201 is rotatably connected to one end of the tank 1, and an activated carbon filter component 202 is rotatably connected to the middle of the tank 1. An intermediate filter component 203 is provided on one side of the activated carbon filter component 202. An ultrafiltration membrane component 204 is rotatably connected to the other end of the tank 1. The drive assembly 3 is located on the top of the tank 1 and includes a dual-axis motor 301. One end of the dual-axis motor 301 is connected to a first output shaft 302, and a gear set 303 is installed at the end of the first output shaft 302. The lower part of the gear set 303 is connected to a drive shaft 304. 4. The filter assembly 2 is fixedly connected. The other end of the dual-axis motor 301 is equipped with a second output shaft 305. The end of the second output shaft 305 is rotatably connected to a transmission box 306. The side of the transmission box 306 is rotatably connected to a drive seat 307. The end of the drive seat 307 is rotatably connected to a connecting rod 308. The lower end of the connecting rod 308 is rotatably connected to a slide rod 309. The bottom of the slide rod 309 is fixed with a diaphragm 310. The outer end of the diaphragm 310 is fixedly connected to a fixed cylinder 311. The side of the fixed cylinder 311 is equipped with an inlet check valve 312. One end of the inlet check valve 312 is connected to a suction pipe 313. The bottom of the fixed cylinder 311 is equipped with an outlet check valve 314. The outlet check valve 314 is connected to the inside of the tank 1 through a pipe. The tank 1 is fixedly connected to the fixed cylinder 311. The specific operation is as follows: When the dual-axis motor 301 is started, it can drive the drive shaft 304 to rotate through the first output shaft 302 and the gear set 303, thereby driving the filter assembly 2 to rotate inside the tank 1. This allows the upper part of the filter assembly 2 to move to the lower part of the tank 1, ensuring full contact with the wastewater, thus improving the utilization rate of consumables. Furthermore, due to its larger size design, the filter assembly 2 has a higher dirt-holding capacity and can maintain an effective filtration state for a longer period of time, thereby significantly extending its maintenance or replacement interval and reducing maintenance frequency and long-term operating costs. At the same time, the dual-axis motor 301 can also drive the slide bar 309 to move back and forth up and down through the second output shaft 305, transmission box 306, drive base 307, and connecting rod 308. When the slide bar 309 pulls up the diaphragm 310, This creates a negative pressure at the lower end of the fixed cylinder 311, thereby drawing wastewater from the external reaction equipment into the lower end of the fixed cylinder 311 through the inlet check valve 312 and the suction pipe 313. When the slide rod 309 pushes the diaphragm 310, the waste liquid at the lower part of the fixed cylinder 311 is squeezed into the tank 1 through the outlet check valve 314, thus automatically drawing in wastewater. This eliminates the need for an independent water pump, its motor, pipelines, and control system, effectively controlling equipment manufacturing costs and floor space, and improving overall economic efficiency. At the same time, the diaphragm 310 is made of corrosion-resistant fluororubber, which can prevent wastewater from corroding the impeller of conventional water pumps and prevent high-speed collisions between particles in the wastewater and the pump blades, thus aggravating wear. It has a service life and reliability far exceeding that of conventional water pumps, greatly reducing maintenance costs and downtime risks caused by pump damage.

[0021] Please see Figure 1 , Figure 5 and Figure 6A cleaning assembly 4 is connected to the upper end of the fixed cylinder 311, and the cleaning assembly 4 includes an inlet check valve 401. An inlet check valve 401 is installed on one side of the upper part of the fixed cylinder 311, and one end of the inlet check valve 401 is connected to a filter cover 402. An outlet check valve 403 is connected to the upper front end of the fixed cylinder 311, and a connecting pipe 404 is fixed to the end of the outlet check valve 403. An air jet pipe 405 is connected to the end of the connecting pipe 404, and the air jet pipe 405 is fixedly connected to the tank body 1. A collection pipe 406 is provided on one side of the filter screen plate 201, and a filtrate screen 407 is fixed to the bottom surface of the middle part of the collection pipe 406. A waste bin 408 is slidably connected to the lower end of the collection pipe 406, and an activated carbon filter plate 409 is installed on the top of the waste bin 408. A shaking component 5 is provided on one side of the screen plate 201, and the shaking component 5 includes a protrusion 501. A protrusion 501 is fixed on one side of the filter screen plate 201, and the protrusion 501 is hemispherical. A first spring seat 502 is installed on the top surface of the middle part of the collection pipe 406, and a stop block 503 is fixed at the end of the first spring seat 502. A second spring seat 504 is installed in the center of the bottom of the collection pipe 406, and a support plate 505 is fixed at the bottom of the second spring seat 504. The support plate 505 is fixedly connected to the tank body 1. A corrugated sealing sleeve 506 is installed on the outer side of the lower part of the collection pipe 406, and the corrugated sealing sleeve 506 is fixedly connected to the tank body 1. A third spring seat 507 is installed on the top of the waste bin 408, and the third spring seat 507 is fixedly connected to the collection pipe 406. The specific operation is as follows: When the diaphragm 310 vibrates up and down, it also changes the air pressure at the upper end of the fixed cylinder 311. When the upper end of the fixed cylinder 311 is under negative pressure, external air is filtered by the filter cover 402 and then supplied to the fixed cylinder 311 through the inlet one-way valve 401. When the air pressure at the upper end of the fixed cylinder 311 increases, air is blown from the jet pipe 405 to one side of the filter screen plate 201 through the outlet one-way valve 403 and the connecting pipe 404. Therefore, when the mesh of the filter screen plate 201 is clogged with a lot of impurities, as the filter screen... The rotation of plate 201 moves the clogged area to one side of the jet pipe 405, where it is forcefully blown back into the collection pipe 406 for collection. This automatically clears the blockage in filter plate 201, preventing the need for a complete shutdown for maintenance due to blockage caused by a large amount of dirt. The airflow then carries impurities through the collection pipe 406 into the waste bin 408 for centralized collection and treatment. Afterward, the airflow is discharged again through activated carbon filter plate 409, preventing pollution of the surrounding environment. Furthermore, during the rotation of filter plate 201... This will also cause the protrusion 501 to move towards the stop 503. At this time, the first spring seat 502 has a large elastic force, so the stop 503 will squeeze the collecting tube 406, causing it to compress the second spring seat 504 and the third spring seat 507. When the horizontal component of the force of the protrusion 501 on the inclined surface of the stop 503 is greater than that of the first spring seat 502, the first spring seat 502 will retract to make way for the protrusion 501. Subsequently, the second spring seat 504 and the third spring seat 507 can drive the collecting tube 406 to move upward and reset, thereby effectively shaking off the residue adhering to the inner wall of the collecting tube 406 using vibration. Impurities are collected to prevent them from accumulating and clogging the pipes, ensuring that they smoothly slide down to the waste bin 408, thus improving the efficiency and reliability of impurity collection. In addition, when some droplets are blown into the upper opening of the collection pipe 406, the waste liquid can be discharged through the filter screen 407, preventing excessive waste liquid from entering the waste bin 408. Furthermore, the corrugated sealing sleeve 506 between the collection pipe 406 and the tank 1 can effectively seal the pipe, preventing leakage of waste gas and wastewater. Its flexible structure also does not hinder the necessary up and down vibration of the collection pipe 406, ensuring the normal realization of the clearing and rapping function.

[0022] Please see Figure 1 and Figure 7A cutting assembly 6 is provided inside one end of the tank body 1, and the cutting assembly 6 includes a vertical rod 601. The vertical rod 601 is slidably connected inside one end of the tank body 1, and a float 602 is placed at the lower end of the vertical rod 601. A guide frame 603 is fixed to the top of the vertical rod 601, and guide grooves 604 are symmetrically opened on both sides of the upper part of the guide frame 603. A sliding column 605 is slidably connected inside the guide groove 604, and a drive sleeve 606 is fixed to one end of the sliding column 605. A first side gear 6 is rotatably connected inside the drive sleeve 606. 07, and a second side gear 608 is fitted into one side of the first side gear 607, and the second side gear 608 is fixedly connected to the drive seat 307. A synchronous shaft 609 is fixedly connected to the other side of the first side gear 607, and a return spring 610 is sleeved on the outer side of one end of the synchronous shaft 609. The return spring 610 abuts against the second output shaft 305, and the second output shaft 305 is slidably connected to the synchronous shaft 609. A liquid outlet pipe 7 is installed at one end of the bottom of the tank body 1, and a waste discharge pipe 8 is fixed at the other end of the bottom of the tank body 1. The specific operation is as follows: After prolonged use, when the filtration rate of filter component 2 gradually decreases below the liquid absorption rate, the liquid level on one side of filter component 2 will gradually rise. When the liquid level in tank 1 is close to the filter screen 407, the float 602 will move the vertical rod 601 upward under the action of a large buoyancy. This causes the vertical rod 601 to push the sliding column 605 through the inclined guide groove 604 on the guide frame 603, thereby causing the drive sleeve 606 to separate the first side gear plate 607 from the second side gear plate 608. This automatically cuts off the transmission between the second output shaft 305 and the drive seat 307. This purely mechanical hard-wired protection method does not rely on any electrical sensors or control systems, and the response is direct and reliable, fundamentally eliminating the possibility of... The rise in liquid level causes some wastewater to enter the waste tank 408 through the upper opening of the filter screen 407 or the collection pipe 406, providing a buffer time for the operator to stop the dual-shaft motor 301 and perform maintenance. When the liquid level inside the tank 1 drops, the float 602 will move the guide frame 603 down synchronously through the vertical rod 601. Similarly, the reset spring 610 will push the second side toothed disc 608 to insert into one side of the first side toothed disc 607, thus automatically restoring the transmission connection and allowing the drive component 3 to resume normal operation. Therefore, without any manual calibration or debugging, the system can automatically restore normal pumping function, which greatly simplifies the restart process after maintenance and improves the ease of use and automation of the equipment.

[0023] In summary, this type of chemical production circulating water system should be used as follows: First, the dual-axis motor 301 is started, and the slide bar 309 is driven to move up and down reciprocally through the second output shaft 305, synchronous shaft 609, first side gear plate 607, second side gear plate 608, drive seat 307 and connecting rod 308. When the slide bar 309 pulls up the diaphragm 310, a negative pressure is formed at the lower end of the fixed cylinder 311, thereby drawing the wastewater generated by the external reaction equipment into the lower end of the fixed cylinder 311 through the liquid inlet check valve 312 and the liquid suction pipe 313. When the slide bar 309 pushes the diaphragm 310, the waste liquid at the bottom of the fixed cylinder 311 is squeezed into the tank 1 through the liquid outlet check valve 314. Secondly, the waste liquid will pass through the filter screen 201, activated carbon filter component 202, intermediate filter component 203 and ultrafiltration membrane component 204 in sequence to filter out impurity particles and adsorb and purify them. During this process, the dual-axis motor 301 will also drive the drive shaft 304 to rotate through the first output shaft 302 and gear set 303, thereby driving the filter component 2 to rotate inside the tank 1, so that the upper part of the filter component 2 can move to the lower part of the tank 1 and fully contact the wastewater, thereby improving the utilization rate of consumables. Afterwards, the filtered water will be discharged through the liquid outlet pipe 7 into the subsequent ultraviolet sterilizer for storage and disinfection, so as to be recycled later. Next, when the diaphragm 310 vibrates up and down, it will also change the air pressure at the upper end of the fixed cylinder 311. When the upper end of the fixed cylinder 311 is under negative pressure, the external air is filtered by the filter cover 402 and then supplied to the fixed cylinder 311 through the inlet one-way valve 401. When the air pressure at the upper end of the fixed cylinder 311 increases, the air will be blown from the jet pipe 405 to one side of the filter screen plate 201 through the outlet one-way valve 403 and the connecting pipe 404. Therefore, when the mesh of the filter screen plate 201 is clogged with a lot of impurities, as the filter screen plate 201 rotates, the clogged part can be moved to one side of the jet pipe 405 and blown back into the collection pipe 406 by the strong airflow, thus automatically clearing the filter screen plate 201. Then the airflow will carry the impurities through the collection pipe 406 into the waste bin 408 for centralized collection and treatment of the impurities. After that, the airflow will be discharged to the outside through the activated carbon filter plate 409 again. Then, during the rotation of the filter plate 201, the protrusion 501 will move towards the stop block 503. At this time, the first spring seat 502 has a large elastic force, so the stop block 503 will squeeze the collection tube 406, causing it to compress the second spring seat 504 and the third spring seat 507. When the horizontal component of the force exerted by the protrusion 501 on the inclined surface of the stop block 503 is greater than that of the first spring seat 502, the first spring seat 502 will retract, making way for the protrusion 501. Subsequently, the second spring seat 504 and the third spring seat 507 can drive the collection tube 406 to move upward and reset. The vibration effectively shakes off impurities adhering to the inner wall of the collection pipe 406, ensuring that the impurities slide smoothly into the waste bin 408, thus improving the efficiency and reliability of impurity collection. In addition, when some droplets are blown into the upper opening of the collection pipe 406, the waste liquid can be discharged through the filter screen 407, preventing excessive waste liquid from entering the waste bin 408. Furthermore, the corrugated sealing sleeve 506 between the collection pipe 406 and the tank 1 can effectively seal and prevent the leakage of waste gas and wastewater, and its flexible structure will not hinder the necessary up and down vibration of the collection pipe 406. Finally, after prolonged use, when the filtration rate of filter assembly 2 gradually decreases below the liquid absorption rate, the liquid level on one side of filter assembly 2 will gradually rise. When the liquid level in tank 1 is close to the filter screen 407, the float 602 will move the vertical rod 601 upward under the action of greater buoyancy. This will cause the vertical rod 601 to push the sliding column 605 through the inclined guide groove 604 on the guide frame 603, thereby causing the drive sleeve 606 to separate the first side gear plate 607 from the second side gear plate 608. This will automatically disconnect the second output shaft 305 from the drive seat 307. The transmission between the two sides prevents some wastewater from entering the waste bin 408 through the upper opening of the filter screen 407 or the collection pipe 406 due to the rise in liquid level. This provides a buffer time for the operator to stop the dual-shaft motor 301 and perform maintenance. When the liquid level inside the tank 1 drops, the float ball 602 will move the guide frame 603 down synchronously through the vertical rod 601. Similarly, the reset spring 610 will push the second side toothed disc 608 to insert into one side of the first side toothed disc 607, which can automatically restore the transmission connection and allow the drive component 3 to resume normal operation.
