Description

Technical Field

[0001] The present invention belongs to the technical field of pesticide production devices, and specifically relates to a pesticide production wastewater treatment device. Background Art

[0002] Under the background of the booming development of modern agriculture, pesticides, as key inputs to ensure the yield and quality of crops, have an expanding production scale. However, the problem of wastewater generated during pesticide production has become increasingly severe, becoming an important factor restricting the sustainable development of the industry and threatening the ecological environment.

[0003] Pesticide production wastewater has a complex composition, often containing high concentrations of organic matter, heavy metals, salts, and various difficult-to-degrade toxic and harmful substances. If directly discharged without effective treatment, it will cause serious pollution to the soil, water bodies, and atmospheric environment, endangering the ecological balance and human health.

[0004] A patent application with the publication number CN109264908A discloses a treatment device for pesticide production wastewater. By setting a filter screen, solid particles in the wastewater are first filtered to prevent them from entering the subsequent process and affecting the service life and effectiveness of the photocatalyst. By setting a first catalytic part, when the wastewater passes through the first catalyst filling layer, it is preliminarily decomposed under the irradiation of the parallel ultraviolet light source layer, and then enters the second catalytic part through the activation layer, and high-molecular-weight organic matter, including difficult-to-degrade organophosphorus pesticides, is fully degraded under the dual conditions of activation and ultraviolet light irradiation. At the same time, the activation layer can also adsorb toxic heavy metal ions. By setting a regenerant addition port and a heating element layer adjacent to the catalyst filling layer, the catalyst filling layer can be quickly regenerated and recycled under the conditions of regenerant and heating.

[0005] When treating pesticide production wastewater, it is necessary to add a reagent to the wastewater to make the two undergo a mixing reaction. In the current prior art, the drug is usually directly put into the wastewater for stirring and mixing. Since the particle sizes in the drug are different, when it is necessary to fully mix the two, it is necessary to stir for a long time, wasting time and being unfavorable for the treatment of sewage during pesticide production.

[0006] Therefore, the present invention provides a pesticide production wastewater treatment device. Summary of the Invention

[0007] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0008] The technical solution adopted by the present invention to solve its technical problems is as follows: A pesticide production wastewater treatment device described in the present invention includes a mixing cylinder. A flow control valve is fixedly installed at the top liquid inlet end of the mixing cylinder, and a ball valve is fixedly installed at the bottom liquid outlet end of the mixing cylinder. A stirring assembly is arranged inside the mixing cylinder, and the stirring assembly is used to mix the medicine and the wastewater. A medicine feeding assembly is arranged outside the mixing cylinder, and the medicine feeding assembly is used to intermittently feed medicine into the mixing cylinder. A medicine dispersing mechanism is arranged inside the mixing cylinder. The medicine dispersing mechanism includes a grinding roller shaft, and the medicine dispersing mechanism is used to drive the grinding roller shaft to grind and disperse the medicine. The medicine dispersing mechanism is placed directly above the stirring assembly, and the medicine feeding assembly is placed outside the medicine dispersing mechanism. By controlling the opening of the flow control valve, wastewater enters the mixing cylinder. When the wastewater completely enters the mixing cylinder, the medicine feeding assembly intermittently feeds medicine into the mixing cylinder. At the same time, the stirring assembly drives the wastewater and the medicine to be stirred and mixed, so that the two are fully mixed and react. When the medicine feeding assembly feeds medicine into the mixing cylinder, the medicine dispersing mechanism drives the grinding roller shaft to grind and disperse the medicine, so that the medicine fed into the mixing cylinder becomes small particles and contacts the wastewater, increasing the contact area between the wastewater and the medicine, accelerating the reaction speed between the two, thereby accelerating the treatment speed of the wastewater and making it more convenient to treat the wastewater during pesticide production. When the mixing reaction of the wastewater and the medicine is completed, by controlling the opening of the ball valve, the mixed and reacted wastewater can be discharged out of the mixing cylinder for the next step of treatment.

[0009] Preferably, the stirring assembly includes a motor. The motor is fixedly installed at the bottom of the mixing cylinder. The output end of the motor is fixedly installed with a shaft rod. The shaft rod is placed inside the mixing cylinder. Stirring rods are fixedly installed on the outer wall of the shaft rod. When stirring is required, the motor drives the shaft rod to rotate. When the shaft rod rotates, it drives the stirring rods to rotate inside the mixing cylinder, so that the stirring rods rotate to drive the wastewater and the medicine to be mixed inside the mixing cylinder, playing a role in mixing the medicine and the wastewater to react and accelerating the reaction between the two.

[0010] Preferably, a retaining disk is fixedly installed on the inner wall of the mixing cylinder. A filter residue plate is slidably connected to the inner wall of the mixing cylinder. A plurality of anti-slip rods are fixedly installed on the top of the retaining disk. The outer walls of the plurality of anti-slip rods are all slidably connected to the inner wall of the filter residue plate. A plurality of return springs are arranged between the top of the retaining disk and the bottom of the filter residue plate. The plurality of return springs are respectively placed outside the plurality of anti-slip rods. When the wastewater flows in from the top of the mixing cylinder, due to the kinetic potential energy generated by the flow of the wastewater, when the water flow falls, the wastewater will push the filter residue plate to squeeze the return springs and slide downward on the anti-slip rods, thereby consuming the potential energy of the water flow when it falls and preventing the filter residue plate from cracking due to excessive potential energy of the water flow. The wastewater will enter the inside of the mixing cylinder through the filter holes on the filter residue plate, and the impurities in the wastewater will be filtered by the filter residue plate on the top of the filter residue plate, playing a role in filtering the impurities in the wastewater and preventing the impurities in the wastewater from accumulating inside the mixing cylinder and affecting the operation.

[0011] Preferably, a plurality of rotating rods are fixedly installed on the outer wall of the top end of the shaft rod. The bottoms of the plurality of rotating rods can all be slidably connected to the top of the filter residue plate. The outer walls of one ends of the plurality of rotating rods are all slidably connected to the inner wall of the liquid mixing cylinder. When the wastewater completely enters the liquid mixing cylinder, the filter residue plate will lose the pushing force. Under the action of the elastic potential energy of the return spring, the filter residue plate will move upward in the liquid mixing cylinder. Through the arrangement of the rotating rods, when the filter residue plate contacts the rotating rods, the top of the filter residue plate will be restricted from moving and stop, so as to reset, playing a role in resetting, and facilitating the subsequent rotation of the rotating rods to remove the impurities remaining on the surface of the filter residue plate from the liquid mixing cylinder.

[0012] Preferably, a plurality of slag placement boxes are fixedly installed on the outer wall of the liquid mixing cylinder. A telescopic cylinder is fixedly installed inside each of the plurality of slag placement boxes. The output ends of the plurality of telescopic cylinders are all fixedly installed with liquid blocking blocks. The inner walls of the plurality of liquid blocking blocks are all slidably connected to the outer wall of the liquid mixing cylinder. A plurality of slag throwing ports are opened on the inner wall of the liquid mixing cylinder. A partition plate is fixedly installed inside each of the plurality of slag placement boxes. The outer walls of the plurality of liquid blocking blocks are respectively slidably connected to the inner sides of the plurality of partition plates. When the filter residue plate stops moving in the liquid mixing cylinder, the motor drives the shaft rod to rotate. When the shaft rod rotates, the shaft rod drives the rotating rods to rotate. When the motor operates, the telescopic cylinder drives the liquid blocking block to slide and reset on the outer wall of the liquid mixing cylinder, so as to open the slag throwing port. Cooperating with the motor to drive the rotating rods to rotate, the impurities placed on the top of the filter residue plate will be driven by the rotating rods to move towards the inner wall of the liquid mixing cylinder, and finally be thrown into the slag placement box through the slag throwing port for storage, preventing the impurities from accumulating on the top of the filter residue plate and affecting the filtering effect of the filter residue plate, playing a role in taking slag from the liquid mixing cylinder.

[0013] Preferably, a plurality of feeding boxes are fixedly installed on the outer wall of the liquid mixing cylinder. A sliding material pipe is fixedly installed on one side of each of the plurality of feeding boxes. One end of each of the plurality of sliding material pipes is placed inside the liquid mixing cylinder. When the motor drives the stirring rod to rotate and stir, the feeding box feeds the medicine into the liquid mixing cylinder through the sliding material pipe, so that the wastewater and the medicine are stirred and mixed. The setting of the feeding box plays a role in placing the medicine.

[0014] Preferably, the dosing assembly includes a stuffing rod. The outer wall of the stuffing rod is slidably connected to the inner walls of the material slide pipe and the liquid mixing cylinder. A push rod spring is provided between the bottom end of the stuffing rod and the outer wall of the liquid mixing cylinder. One end of the rotating rod can be slidably connected to the top of the stuffing rod. One end of the rotating rod and the top end of the stuffing rod are both inclined sliding surfaces. When the motor drives the stirring rod to rotate, the motor simultaneously drives the rotating rod to rotate. When the rotating rod rotates, one end of the rotating rod will squeeze and push the stuffing rod to slide in the material slide pipe. When the stuffing rod is pressed into the material slide pipe, the opening on the stuffing rod just coincides with the diameter of the material slide pipe. The medicine placed in the feeding box will then slide into the material slide pipe through the opening on the stuffing rod and finally slide into the liquid mixing cylinder. Since there is a certain distance between multiple rotating rods, when multiple rotating rods rotate, the medicines in multiple feeding boxes will enter the material slide pipe intermittently, playing a role in intermittently feeding the medicine into the liquid mixing cylinder.

[0015] Preferably, the medicine scattering mechanism further includes an axle box. The axle box is fixedly installed at the bottom of the retaining disk. The outer wall of the axle rod is rotatably connected to the inner wall of the axle box. A mother wheel is fixedly installed on the outer wall of the axle box. A plurality of cylinder cavities are fixedly installed on the inner wall of the axle box. The tops of the plurality of cylinder cavities are rotatably connected to child wheels. The teeth on the plurality of child wheels are all engaged with the teeth on the mother wheel. One side of each of the plurality of child wheels is fixedly installed with a round rod. The plurality of round rods are respectively placed inside the plurality of cylinder cavities. Axial flow fans are fixedly installed on the outer walls of the plurality of round rods. One ends of the plurality of material slide pipes are respectively fixedly connected to the inner walls of the plurality of cylinder cavities. When the medicine enters the material slide pipe, the medicine will enter the cylinder cavity. Through the continuous rotation of the axle rod, the axle rod will drive the mother wheel to rotate. When the mother wheel rotates, through the tooth engagement, the mother wheel will drive the plurality of child wheels to rotate. When the child wheels rotate, the child wheels will drive the axial flow fans to rotate inside the cylinder cavity through the round rods, so that the axial flow fans blow the medicine entering the cylinder cavity out of the cylinder cavity. Driven by the wind force of the axial flow fans, the medicine placed in the cylinder cavity will be scattered into the waste water in the liquid mixing cylinder, accelerating the flow rate of the medicine and increasing the diffusion area of the medicine in the liquid mixing cylinder, which is more conducive to the mixing reaction between the waste water and the medicine.

[0016] Preferably, a discharge filter plate is fixedly installed at the bottom of the cylinder cavity. Ring openings are provided on the inner walls of both the discharge filter plate and the round rod. A grinding rod is slidably connected to the inner walls of the two ring openings. A grinding roller shaft is rotatably connected to the outer wall of the grinding rod. A rotating shaft is fixedly installed at the bottom end of the round rod. A pushing block is fixedly installed on the outer wall of the rotating shaft. The outer wall of the pushing block can be attached to one end of the grinding rod. When the round rod rotates, the round rod drives the pushing block to rotate through the rotating shaft, so that the pushing block pushes the grinding rod to move within the ring opening. When the grinding rod moves within the ring opening, the grinding rod will drive the grinding roller shaft to roll and grind on the inner wall of the cylinder cavity, thereby grinding large-particle drugs in the medicine into small-particle drugs. Finally, with the blowing of the axial-flow fan, the small-particle drugs will be blown out from the discharge filter plate into the cylinder cavity and finally enter the mixing cylinder to contact and mix with the wastewater, playing a role in grinding the drugs and preventing the phenomenon that it is not conducive to full reaction when large-particle drugs are stirred and mixed with the wastewater.

[0017] Preferably, a material blocking plate is fixedly installed on the outer wall of the shaft rod. The material blocking plate is slidably connected to the bottom of the shaft box. A plurality of round openings are provided on the inner wall of the material blocking plate. The number of the plurality of round openings is the same as the number of the plurality of cylinder cavities. When the shaft rod rotates, the shaft rod drives the material blocking plate to rotate together, so that when the medicine placed in the cylinder cavity flows towards the wastewater in the mixing cylinder under the blowing of the axial-flow fan, the material blocking plate intermittently blocks the discharge filter plate. On the one hand, it can reduce the waste of medicine and save resources. On the other hand, it can provide a certain pause time for the mixing and stirring of the medicine and the wastewater, which is more conducive to their mixing.

[0018] The beneficial effects of the present invention are as follows: 1. For a pesticide production wastewater treatment device of the present invention, the round rod drives the pushing block to rotate, so that the pushing block pushes the grinding rod to move within the ring opening. When the grinding rod moves within the ring opening, the grinding rod will drive the grinding roller shaft to roll and grind on the inner wall of the cylinder cavity, thereby grinding large-particle drugs in the medicine into small-particle drugs. With the blowing of the axial-flow fan, the small-particle drugs will be blown out from the discharge filter plate into the cylinder cavity and finally enter the mixing cylinder to contact and mix with the wastewater, playing a role in grinding the drugs and preventing the phenomenon that it is not conducive to full reaction when large-particle drugs are stirred and mixed with the wastewater.

[0019] 2. For a pesticide production wastewater treatment device of the present invention, when the medicine enters the cylinder cavity, the shaft rod will drive the mother wheel to rotate. Through the meshing of the teeth, the mother wheel will drive a plurality of sub-wheels to rotate. The sub-wheels will drive the axial-flow fan to rotate within the cylinder cavity through the round rod, so that the axial-flow fan blows the medicine entering the cylinder cavity out of the cylinder cavity. Through the blowing force of the axial-flow fan, the medicine placed in the cylinder cavity will fall into the wastewater in the mixing cylinder, accelerating the flow rate of the medicine and increasing the diffusion area of the medicine in the mixing cylinder, which is more conducive to the mixing reaction between the wastewater and the medicine.

[0020] 3. In a pesticide production wastewater treatment device according to the present invention, when the motor drives the rotating rod to rotate, one end of the rotating rod will squeeze and push the blocking rod to slide in the material sliding pipe. When the blocking rod is pressed into the material sliding pipe, the opening on the blocking rod just coincides with the diameter of the material sliding pipe, and the medicine placed in the feeding box will slide into the material sliding pipe through the opening on the blocking rod and finally slide into the mixing cylinder. Since there is a certain distance between multiple rotating rods, when multiple rotating rods rotate, the medicines in multiple feeding boxes will enter the material sliding pipe intermittently, playing a role of intermittently feeding medicines into the mixing cylinder.

[0021] 4. In a pesticide production wastewater treatment device according to the present invention, when the filter residue plate stops moving in the mixing cylinder, the motor drives the shaft rod to rotate. When the shaft rod rotates, the shaft rod drives the rotating rod to rotate. When the motor operates, the telescopic cylinder drives the liquid blocking block to slide and reset on the outer wall of the mixing cylinder, so that the slag discharging port is opened. Cooperating with the motor driving the rotating rod to rotate, the impurities placed on the top of the filter residue plate will be driven by the rotating rod to move towards the inner wall of the mixing cylinder and finally be thrown into the slag storage box through the slag discharging port for storage, preventing the impurities from accumulating on the top of the filter residue plate and affecting the filtering effect of the filter residue plate, playing a role of taking out slag from the mixing cylinder.

A medicine dispersing mechanism is arranged inside the mixed liquid cylinder 1, and the medicine dispersing mechanism includes a grinding roller shaft 806. The medicine dispersing mechanism is used for driving the grinding roller shaft 806 to grind and disperse the medicine. The medicine dispersing mechanism is placed directly above the stirring assembly, and the medicine feeding assembly is placed outside the medicine dispersing mechanism; Since the particle sizes of the medicines are different, when it is necessary to fully mix the two, it is necessary to stir for a long time, which not only wastes time but also is not conducive to the treatment of sewage during pesticide production; By controlling the opening of the flow control valve 10 to allow the wastewater to enter the mixed liquid cylinder 1. When the wastewater completely enters the mixed liquid cylinder 1, the medicine feeding assembly intermittently feeds medicine into the mixed liquid cylinder 1. At the same time, the stirring assembly drives the wastewater and the medicine to be stirred and mixed, so that the two are fully mixed and react. When the medicine feeding assembly feeds medicine into the mixed liquid cylinder 1, the medicine dispersing mechanism drives the grinding roller shaft 806 to grind and disperse the medicine, so that the medicine fed into the mixed liquid cylinder 1 becomes small particles and contacts the wastewater, increasing the contact area between the wastewater and the medicine and accelerating the reaction speed between the two, thereby accelerating the wastewater treatment speed and making it more convenient for the treatment of wastewater during pesticide production. When the mixing reaction of the wastewater and the medicine is completed, by controlling the opening of the ball valve 11, the mixed and reacted wastewater can be discharged out of the mixed liquid cylinder 1 for the next step of treatment. It should be noted here that the medicine refers to solid mixed medicines, such as sodium hydroxide, solid chlorine dioxide disinfectant, etc.

The wastewater will enter the inside of the liquid mixing cylinder 1 through the filter holes on the filter residue plate 7, and the impurities in the wastewater will be filtered by the filter residue plate 7 on the top of the filter residue plate 7, playing a role in filtering the impurities in the wastewater and preventing the impurities in the wastewater from accumulating inside the liquid mixing cylinder 1 and affecting the operation.

The outer wall of the push block 809 can be attached to one end of the grinding rod 8011; When the round rod 804 rotates, the round rod 804 drives the push block 809 to rotate through the rotating shaft 808, so that the push block 809 pushes the grinding rod 8011 to move in the ring opening 8010. When the grinding rod 8011 moves in the ring opening 8010, the grinding rod 8011 will drive the grinding roller shaft 806 to roll and grind on the inner wall of the cylinder cavity 801, so as to grind the large particle drugs in the drug into small particle drugs. Finally, with the blowing of the axial flow fan 805, the small particle drugs will be blown out of the discharge filter plate 807 into the cylinder cavity 801 and finally enter the mixing cylinder 1 to contact and mix with the waste water, playing a role in grinding the drug and preventing the phenomenon that it is not conducive to full reaction when the large particle drugs are stirred and mixed with the waste water.

[0035] As shown Figures 6 to 9 in the figure, a baffle plate 9 is fixedly installed on the outer wall of the shaft rod 302. The baffle plate 9 is slidably connected to the bottom of the shaft box 8. A plurality of circular openings are formed in the inner wall of the baffle plate 9, and the number of the plurality of circular openings is the same as the number of the plurality of cylindrical cavities 801; When the shaft rod 302 rotates, the shaft rod 302 drives the baffle plate 9 to rotate together. When the drug placed in the cylindrical cavity 801 flows towards the wastewater in the mixing cylinder 1 under the blowing of the axial flow fan 805, the baffle plate 9 intermittently blocks the discharge filter plate 807. On the one hand, it can reduce the waste of drugs and save resources. On the other hand, it can provide a certain intermittent time for the mixing and stirring of the drug and the wastewater, which is more conducive to their mixing.

[0036] Working principle: By controlling the flow control valve 10 to open, wastewater enters the mixing cylinder 1. When the wastewater completely enters the mixing cylinder 1, the drug feeding assembly intermittently feeds drugs into the mixing cylinder 1. At the same time, the stirring assembly drives the wastewater and the drug to be stirred and mixed, so that the two are fully mixed and reacted. When the drug feeding assembly feeds drugs into the mixing cylinder 1, the drug scattering mechanism drives the grinding roller shaft 806 to grind and scatter the drugs, so that the drugs fed into the mixing cylinder 1 become small particles and come into contact with the wastewater, increasing the contact area between the wastewater and the drug, accelerating the reaction speed between the two, thus accelerating the treatment speed of the wastewater and making it more convenient for the treatment of wastewater during pesticide production. When the mixing reaction of the wastewater and the drug is completed, by controlling the ball valve 11 to open, the mixed and reacted wastewater can flow out of the mixing cylinder 1 for the next step of treatment; When stirring is required, the motor 3 drives the shaft rod 302 to rotate. When the shaft rod 302 rotates, it drives the stirring rod 301 to rotate in the mixing cylinder 1, so that the stirring rod 301 rotates to drive the wastewater and the drug to be mixed in the mixing cylinder 1, playing a role in mixing the drug and the wastewater reaction and accelerating the reaction between the two; When the wastewater flows into the mixing cylinder 1 from the top, due to the dynamic potential energy generated by the flow rate of the wastewater, when the water flow falls, the wastewater will push the filter residue plate 7 to squeeze the return spring 701 and slide downward on the anti-slip rod 702, thereby consuming the potential energy when the water flow falls and preventing the filter residue plate 7 from cracking due to the excessive potential energy of the water flow. The wastewater will pass through the filter holes on the filter residue plate 7 and enter the inside of the mixing cylinder 1. The impurities in the wastewater will be filtered by the filter residue plate 7 on the top of the filter residue plate 7, playing a role in filtering the impurities in the wastewater and preventing the impurities in the wastewater from accumulating in the mixing cylinder 1 and affecting the operation; When the wastewater completely enters the mixing cylinder 1, the filter residue plate 7 will lose the pushing force. Under the action of the elastic potential energy of the return spring 701, the filter residue plate 7 will move upward in the mixing cylinder 1. Through the setting of the rotating rod 4, when the filter residue plate 7 touches the rotating rod 4, the top of the filter residue plate 7 will be limited and stop moving, thus resetting and playing a reset role, which is convenient for the rotating rod 4 to rotate later to pick out the impurities remaining on the surface of the filter residue plate 7 from the mixing cylinder 1; When the filter residue plate 7 stops moving in the mixing cylinder 1, the motor 3 drives the shaft rod 302 to rotate. When the shaft rod 302 rotates, the shaft rod 302 drives the rotating rod 4 to rotate. When the motor 3 operates, the telescopic cylinder 503 drives the liquid blocking block 501 to slide and reset on the outer wall of the mixing cylinder 1, so that the slag throwing port 502 is opened. Cooperating with the motor 3 driving the rotating rod 4 to rotate, the impurities placed on the top of the filter residue plate 7 will be driven by the rotating rod 4 to move towards the inner wall of the mixing cylinder 1 and finally be thrown into the slag storage box 5 through the slag throwing port 502 for storage, preventing the impurities from accumulating on the top of the filter residue plate 7 and affecting the filtering effect of the filter residue plate 7, playing a role of taking out the slag from the mixing cylinder 1; When the motor 3 drives the stirring rod 301 to rotate and stir, the feeding box 2 inputs drugs into the mixing cylinder 1 through the sliding material pipe 201, so that the wastewater and the drugs are stirred and mixed. The setting of the feeding box 2 plays a role of placing the drugs; When the motor 3 drives the stirring rod 301 to rotate, the motor 3 simultaneously drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, one end of the rotating rod 4 will squeeze and push the material blocking rod 202 to slide in the sliding material pipe 201. When the material blocking rod 202 is pressed into the sliding material pipe 201, the opening on the material blocking rod 202 just coincides with the diameter of the sliding material pipe 201, and the drugs placed in the feeding box 2 will slide into the sliding material pipe 201 through the opening on the material blocking rod 202 and finally slide into the mixing cylinder 1. Since there is a certain distance between multiple rotating rods 4, when multiple rotating rods 4 rotate, the drugs in multiple feeding boxes 2 will enter the sliding material pipe 201 in an intermittent manner, playing a role of intermittently feeding drugs into the mixing cylinder 1; When the drugs enter the sliding material pipe 201, the drugs will enter the cylinder cavity 801. Through the continuous rotation of the shaft rod 302, the shaft rod 302 will drive the mother wheel 802 to rotate. When the mother wheel 802 rotates, through the tooth engagement, the mother wheel 802 will drive multiple sub - wheels 803 to rotate. When the sub - wheels 803 rotate, the sub - wheels 803 will drive the axial flow fan 805 to rotate in the cylinder cavity 801 through the round rod 804, so that the axial flow fan 805 blows the drugs entering the cylinder cavity 801 out of the cylinder cavity 801. Through the blowing force of the axial flow fan 805, the drugs placed in the cylinder cavity 801 will be scattered into the wastewater in the mixing cylinder 1, accelerating the flow speed of the drugs and increasing the diffusion area of the drugs in the mixing cylinder 1, which is more conducive to the mixing reaction between the wastewater and the drugs; When the round rod 804 rotates, the round rod 804 drives the push block 809 to rotate through the rotating shaft 808, so that the push block 809 pushes the grinding rod 8011 to move within the annular opening 8010. When the grinding rod 8011 moves within the annular opening 8010, the grinding rod 8011 drives the grinding roller shaft 806 to roll and grind on the inner wall of the cylinder cavity 801, thereby grinding large particle drugs in the medicine into small particle drugs. Finally, with the blowing of the axial flow fan 805, the small particle drugs will be blown out from the discharge filter plate 807 into the cylinder cavity 801, and finally enter the mixing cylinder 1 to contact and mix with the waste water, playing a role in grinding the medicine and preventing the phenomenon that it is not conducive to full reaction when large particle drugs are stirred and mixed with the waste water. When the shaft rod 302 rotates, the shaft rod 302 drives the baffle plate 9 to rotate together. Thus, when the medicine placed in the cylinder cavity 801 flows towards the waste water in the mixing cylinder 1 under the blowing of the axial flow fan 805, the baffle plate 9 intermittently blocks the discharge filter plate 807. On the one hand, it can reduce the waste of medicine and save resources. On the other hand, it can provide a certain pause time for the mixing and stirring of the medicine and the waste water, which is more conducive to their mixing.
