Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically an agricultural engineering wastewater treatment device. Background Technology

[0002] Agricultural wastewater mainly originates from agricultural production activities such as crop cultivation, livestock breeding, and agricultural product processing. Its composition is complex, containing large amounts of organic matter, suspended solids, phosphorus nutrients, and pesticide residues. If this wastewater is discharged directly without treatment, it will cause serious pollution to water bodies, soil, and the ecological environment, and may even threaten human health.

[0003] Existing technologies have also proposed some solutions for agricultural wastewater treatment. For example, a Chinese patent application with publication number CN208265902U discloses an agricultural wastewater treatment device, including a base plate. Columns are fixedly connected to both sides of the bottom of the base plate, and a disinfection tank is fixedly connected to the left side of the top of the base plate. A dosing port is opened on the left side of the top of the disinfection tank, and a motor is fixedly connected to the center of the top of the disinfection tank. This technical solution achieves the advantage of good filtration effect, solves the problem of poor filtration effect in existing agricultural wastewater treatment devices, allows pesticide wastewater to be recycled or safely discharged, and improves the practicality of agricultural wastewater treatment devices.

[0004] Although the above technical solution solves the problem of poor filtration effect of existing agricultural wastewater treatment devices, other problems still exist in actual use. For example, after a long period of filtration, the filter plate often suffers from excessive impurities adhering to its surface, which affects the flow of wastewater and is not conducive to the treatment of agricultural engineering wastewater.

[0005] Therefore, the present invention provides an agricultural engineering wastewater treatment device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The agricultural engineering wastewater treatment device of the present invention includes a treatment base, a treatment pipe installed above the treatment base, the treatment pipe being connected to an external water inlet pipe, and multiple filter plates installed inside the treatment pipe. The multiple filter plates are designed to be separated from each other. The filter plates are used to block impurities in the wastewater. Each filter plate has a scraper on its front end face. The scraper can move from top to bottom along the front end face of the filter plate and scrape off the impurities adhering to the front end face of the filter plate.

[0008] Preferably, the processing pipe is internally equipped with multiple rotating shafts located behind the filter plate. Multiple sets of blades are fixedly mounted on the outer circumference of each rotating shaft. The rotating shafts are connected by a belt. One end of one rotating shaft is connected to the output of an external drive motor. A speed sensor and a linkage unit are installed at the end of each rotating shaft to drive the scraper. During operation, after the filter plate has pre-treated the wastewater, the wastewater flows to one side of the rotating shaft. Because multiple sets of blades are installed on the outer circumference of the rotating shaft, it rotates at a certain speed under the impact of the water flow. This, in turn, drives the scraper to move up and down through the linkage unit, allowing the wastewater to simultaneously scrape away impurities adhering to the front surface of the filter plate during the flow process, making operation convenient.

[0009] Preferably, the linkage unit includes a connecting shaft fixedly installed at the end of the rotating shaft, a horizontal shaft rotatably arranged above the processing pipe, the end of the horizontal shaft and the end of the connecting shaft being connected by a belt, a pressure column installed above the scraper, the top end of the pressure column being slidably disposed inside the processing pipe, and a limiting protrusion fixedly installed on the outer circumferential surface of the horizontal shaft, the protruding surface of the limiting protrusion contacting the top end of the pressure column.

[0010] Preferably, the processing pipe is provided with a limiting groove adapted to the pressure column, and the pressure column is slidably disposed in the limiting groove by a support rod. A limiting spring is fixed to the groove wall of the limiting groove, and the end of the limiting spring away from the limiting groove is connected to the support rod on the side wall of the pressure column. The distance by which the limiting protrusion presses down on the pressure column is greater than the diameter of the filter plate. During operation, when the pressure column moves downward, it will drive the support rod on its side wall to move downward along the limiting groove and squeeze the limiting spring on the groove wall. When the protruding end of the limiting protrusion moves away from the top of the pressure column, the pressure column will move upward under the action of the limiting spring, thereby causing the scraper to move upward again to process the impurities on the filter plate.

[0011] Preferably, the processing pipe has a drug storage chamber inside, which can move left and right inside the processing pipe. The drug storage chamber stores purification pills inside, and the surface of the drug storage chamber has multiple holes and grooves.

[0012] Preferably, a rack is slidably disposed above the processing pipe, a drug delivery pipe is installed above the drug storage chamber, the side wall of the drug delivery pipe is connected to the side wall of the rack through a bracket, an incomplete helical gear is rotatably disposed above the processing pipe, the incomplete helical gear meshes with the rack; a driven unit is disposed on the side of the incomplete helical gear, and the connecting shaft drives the incomplete helical gear to rotate through the driven unit.

[0013] Preferably, the incomplete helical gear is rotatably mounted above the processing pipe via a bracket. The driven unit includes a rotating rod installed at the connection between the incomplete helical gear and the bracket. The connecting shaft and the rotating rod are connected by a belt. During operation, when the connecting shaft rotates, the connecting shaft will drive the rotating rod to rotate via the belt. The rotating rod will drive the incomplete helical gear to rotate, thereby driving the rack to move, which facilitates the left and right movement of the medicine storage chamber.

[0014] Preferably, a temporary storage ring is provided inside the medicine storage cavity, and rectangular grooves are symmetrically arranged on the inner wall of the medicine delivery tube. A tension spring is fixedly installed on the groove wall of the rectangular groove, and a pull rod is fixedly installed at the bottom of the tension spring. The bottom of the pull rod is connected to the side wall of the temporary storage ring, and the pull rod is slidably disposed inside the rectangular groove.

[0015] Preferably, the side wall of the pull rod is equipped with a contact point one, the wall of the rectangular groove is equipped with a contact point two, the side wall of the delivery tube is equipped with a fixing frame, the surface of the fixing frame is equipped with an electric telescopic rod, the telescopic end of the electric telescopic rod is fixedly equipped with a limit frame, the limit frame is slidably disposed in the delivery tube, the limit frame is used to limit the processing of pills and deliver pills one by one into the temporary storage ring; during operation, when the temporary storage ring drives the pull rod to move down and pulls the tension spring, the pull rod will drive contact point one away from contact point two. As the pills dissolve in the wastewater, the tension spring will gradually drive the pull rod and the temporary storage ring to move up, that is, the pull rod will gradually drive contact point one to move up. When contact point one contacts contact point two, the pills are about to completely dissolve, and the external circuit is connected. The external controller will control the electric telescopic rod to move, so that the telescopic end of the electric telescopic rod drives the limit frame to move, delivering the pills one by one into the temporary storage ring.

[0016] Preferably, the surface of the limiting frame is equipped with a limiting plate one and a limiting plate two, the limiting plate one and the limiting plate two are designed to be separated into upper and lower parts, and the surface of the limiting plate one is provided with a material passage groove.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The agricultural engineering wastewater treatment device of the present invention, after the wastewater is initially treated by the filter plate, the wastewater flows to one side of the rotating shaft. Since multiple sets of blades are set on the outer circumference of the rotating shaft, the rotating shaft will rotate at a certain speed under the impact of the water flow. Then, through the action of the linkage unit, the scraper moves up and down, so that the wastewater simultaneously scrapes off the impurities adhering to the front end of the filter plate during the flow process, which is relatively convenient to operate.

[0019] 2. The agricultural engineering wastewater treatment device of the present invention uses an incomplete helical gear to drive the meshing rack to move. The rack drives the drug delivery pipe and the drug storage chamber to move through the support. That is, the drug storage chamber moves left and right in the wastewater. Moreover, multiple sets of drug storage chambers are set up, which can make the pills inside the drug storage chamber uniformly dispersed in the wastewater, so that the dispersed drug liquid can maximize the combination with the wastewater and improve the wastewater treatment effect.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 6 As shown in the figure, an agricultural wastewater treatment device according to an embodiment of the present invention includes a treatment base 1. A treatment pipe 2 is installed above the treatment base 1 and is connected to an external water inlet pipe. Multiple filter plates 3 are installed inside the treatment pipe 2. The filter plates 3 are designed to be separated from each other. The filter plates 3 are used to block impurities in the wastewater. Each filter plate 3 has a scraper 301 on its front end face. The scraper 301 can move from top to bottom along the front end face of the filter plate 3 and scrape off the impurities adhering to the front end face of the filter plate 3.

[0036] During operation, wastewater generated in agricultural engineering is connected to the end of treatment pipe 2 through an external inlet pipe. Then, under the obstruction of multiple filter plates 3 inside treatment pipe 2, larger impurities in the wastewater can be blocked and pre-treated, which facilitates subsequent treatment of wastewater. Moreover, under the action of scraper 301, it can move from top to bottom along the front end face of filter plate 3, which is conducive to scraping off larger impurities adhering to the front end face of filter plate 3, avoiding the problem of large impurities such as plastic and other leaves clogging the filter holes of filter plate 3 and affecting the passage of wastewater through the surface of filter plate 3. It is also conducive to the centralized treatment of impurities blocked on the surface of filter plate 3 in the later stage.

[0037] It should be noted that the front end of filter plate 3 faces the inlet direction of wastewater, and multiple filter plates 3 are set up to achieve multiple treatment effects.

[0038] The processing pipe 2 is internally equipped with a rotating shaft 4. Multiple rotating shafts 4 are located behind the filter plate 3. Multiple sets of blades 5 are fixedly installed on the outer circumference of the rotating shaft 4. The rotating shafts 4 are connected by a belt. One end of the rotating shaft 4 is connected to the output end of an external drive motor. A speed sensor is installed at the end of the rotating shaft 4. A linkage unit is installed at the end of the rotating shaft 4 to drive the scraper 301 to move. During operation, after the filter plate 3 has initially treated the wastewater, the wastewater will flow to one side of the rotating shaft 4. Since multiple sets of blades 5 are installed on the outer circumference of the rotating shaft 4, the rotating shaft 4 will rotate at a certain speed under the impact of the water flow. Then, under the action of the linkage unit, the scraper 301 will move up and down, so that the wastewater can simultaneously scrape off the impurities adhering to the front end of the filter plate 3 during the flow process, which is convenient to operate.

[0039] It should be noted that a speed sensor is installed at the end of the rotating shaft 4, and a minimum threshold is set for the rotation speed of the rotating shaft 4. When the rotation speed of the rotating shaft 4 is less than the minimum threshold, the speed sensor will transmit a signal to the controller, so that the controller controls the external drive motor to drive the rotating shaft 4 to rotate. This ensures the up and down movement of the scraper 301 and improves the treatment efficiency of wastewater.

[0040] like Figures 2 to 8 As shown, the linkage unit includes a connecting shaft 6 fixedly installed at the end of the rotating shaft 4, a horizontal shaft 7 rotatably arranged above the processing pipe 2, the end of the horizontal shaft 7 and the end of the connecting shaft 6 are connected by a belt 8, a pressure column 9 is installed above the scraper 301, the top end of the pressure column 9 is slidably disposed inside the processing pipe 2, and a limiting protrusion 10 is fixedly installed on the outer circumferential surface of the horizontal shaft 7, the protruding surface of the limiting protrusion 10 is in contact with the top end of the pressure column 9;

[0041] During operation, when the rotating shaft 4 rotates, it will simultaneously drive the connecting shaft 6 to rotate. The connecting shaft 6 will drive the horizontal shaft 7 to rotate via the belt 8. The horizontal shaft 7 will drive the limiting protrusion 10 connected to it to rotate. During the rotation, the protruding surface of the limiting protrusion 10 will contact the top of the pressure column 9, and the pressure column 9 will move downward under pressure. Therefore, the scraper 301 will automatically process the impurities adhering to the front surface of the filter plate 3, saving time and effort, and avoiding the problem of excessive impurities adhering to the front surface of the filter plate 3 affecting the flow of wastewater.

[0042] The processing pipe 2 is provided with a limiting groove 11 that is adapted to the pressure column 9. The pressure column 9 is slidably disposed in the limiting groove 11 by a support rod. A limiting spring 12 is fixedly connected to the groove wall of the limiting groove 11. The end of the limiting spring 12 away from the limiting groove 11 is connected to the support rod on the side wall of the pressure column 9. The distance by which the limiting protrusion 10 presses down on the pressure column 9 is greater than the diameter of the filter plate 3.

[0043] During operation, when the pressure column 9 moves downward, it will drive the support rod on its side wall to move downward along the limiting groove 11 and squeeze the limiting spring 12 on the groove wall of the limiting groove 11. When the protruding end of the limiting protrusion 10 moves away from the top of the pressure column 9, the pressure column 9 will move upward under the action of the limiting spring 12, thereby causing the scraper 301 to move upward again to process the impurities on the filter plate 3.

[0044] It should be noted that the elastic restoring force of the limiting spring 12 and the pressure of the limiting protrusion 10 on the pressure column 9 are both greater than the pressure of the wastewater impacting the scraper 301, which facilitates the up and down movement of the scraper 301.

[0045] like Figures 3 to 10 As shown, the processing pipe 2 has a drug storage chamber 13 inside, which can move left and right inside the processing pipe 2. The drug storage chamber 13 stores purification pills, and its surface has multiple slots. During operation, refer to the attached diagram. Figure 5 As shown, multiple drug storage chambers 13 are set up during the wastewater flow process, and the drug storage chambers 13 move left and right inside the treatment pipe 2. As a result, the purification pills inside them dissolve in the wastewater during the left and right movement, which improves the uniform dispersion of the purification pills in the wastewater, thereby improving the wastewater treatment efficiency.

[0046] like Figures 3 to 12 As shown, a rack 14 is slidably mounted above the processing pipe 2, and a drug delivery pipe 15 is installed above the drug storage chamber 13. The side wall of the drug delivery pipe 15 is connected to the side wall of the rack 14 via a bracket. An incomplete helical gear 201 is rotatably mounted above the processing pipe 2, and the incomplete helical gear 201 meshes with the rack 14. A driven unit is arranged on the side of the incomplete helical gear 201, and the connecting shaft 6 drives the incomplete helical gear 201 to rotate through the driven unit. During operation, when the connecting shaft 6 rotates, the incomplete helical gear 201 rotates. When the connecting shaft 6 rotates with the rotating shaft 4, the connecting shaft 6 will drive the incomplete helical gear 201 to rotate through the driven unit. The incomplete helical gear 201 will drive the rack 14 meshing with it to move. The rack 14 will drive the drug delivery tube 15 and the drug storage chamber 13 to move through the bracket. That is, the drug storage chamber 13 will move left and right in the wastewater. Moreover, multiple sets of drug storage chambers 13 are set up, which can make the pills inside the drug storage chamber 13 evenly dispersed in the wastewater, so that the dispersed drug liquid can maximize the combination with the wastewater and improve the wastewater treatment effect.

[0047] The incomplete helical gear 201 is rotatably mounted above the processing pipe 2 via a bracket. The driven unit includes a rotating rod 16 installed at the connection between the incomplete helical gear 201 and the bracket. The connecting shaft 6 and the rotating rod 16 are connected by a belt. During operation, when the connecting shaft 6 rotates, the connecting shaft 6 will drive the rotating rod 16 to rotate via the belt. The rotating rod 16 will drive the incomplete helical gear 201 to rotate, thereby driving the rack 14 to move, which facilitates the left and right movement of the medicine storage chamber 13.

[0048] It should be noted that, referring to Figure 7 As shown, the rack 14 is slidably mounted above the processing pipe 2 via a bracket. A groove is provided on the side wall of the rack 14, and a spring is installed inside the groove. One end of the spring is connected to the bracket connected to the rack 14. Thus, when the incomplete helical gear 201 is not meshed with the rack 14 and the spring is in a stretched state, the rack 14 can be moved under the elastic force of the spring, thus facilitating the left and right movement of the rack 14.

[0049] The medicine storage chamber 13 is equipped with a temporary storage ring 17. The inner wall of the medicine delivery tube 15 has symmetrically arranged rectangular grooves 18. A tension spring 19 is fixedly installed on the wall of each rectangular groove 18, and a pull rod 20 is fixedly installed at the bottom of each tension spring 19. The bottom of the pull rod 20 is connected to the side wall of the temporary storage ring 17, and the pull rod 20 is slidably disposed inside the rectangular groove 18. During operation, refer to the attached diagram. Figure 6 and Figure 11 As shown, when the storage chamber 13 is located inside the treatment pipe 2, the treatment pill inside it will be located in the temporary storage ring 17. As the storage chamber 13 moves left and right, the wastewater combines with the treatment pill through the holes and grooves on the surface of the storage chamber 13, and gradually dissolves in the wastewater as the storage chamber 13 moves. When the treatment pill is inside the temporary storage ring 17, the temporary storage ring 17 will be subjected to its pressure and drive the pull rod 20 to move down, and will pull the tension spring 19. This makes it easy for the treatment pill to be immersed in the wastewater and move with the movement of the storage chamber 13.

[0050] It should be noted that the weight of the pill is greater than the density of the wastewater, and the weight of the pill is much greater than the elastic potential energy of the tension spring 19, so that the pill can easily fall into the temporary storage ring 17.

[0051] The pull rod 20 has a contact point 21 installed on its side wall, the rectangular groove 18 has a contact point 22 installed on its groove wall, the delivery tube 15 has a fixing frame 23 installed on its side wall, the fixing frame 23 has an electric telescopic rod 24 installed on its surface, and the telescopic end of the electric telescopic rod 24 has a limit frame 25 fixedly installed. The limit frame 25 is slidably disposed in the delivery tube 15. The limit frame 25 is used to limit the movement of the processed pills and deliver the pills one by one into the temporary storage ring 17. During operation, when the temporary storage ring 17 drives the pull rod 20 to move downward and pulls it, the pull rod 20 is extended. When the spring 19 is engaged, the pull rod 20 will move the contact 1 21 away from the contact 22. As the pill dissolves in the wastewater, the tension spring 19 will gradually move the pull rod 20 and the temporary storage ring 17 upward. That is, the pull rod 20 will gradually move the contact 1 21 upward. When the contact 1 21 contacts the contact 22, the pill is about to completely dissolve, and the external circuit is connected. The external controller will control the electric telescopic rod 24 to move, so that the telescopic end of the electric telescopic rod 24 drives the limit frame 25 to move, and the pills are delivered one by one into the temporary storage ring 17.

[0052] It should be noted that the elastic potential energy of the tension spring 19 is greater than the weight of the temporary storage ring 17, and contacts 1 and 22 do not come into contact with the wastewater.

[0053] Limiting plate 251 and limiting plate 252 are mounted on the surface of the limiting frame 25. The limiting plate 251 and limiting plate 252 are designed to be separated vertically. The surface of limiting plate 251 has a material passage groove 26. During operation, when contact point 1 21 and contact point 22 are not in contact, that is, when the pill has not completely dissolved, the positions of limiting plate 251 and limiting plate 252 are as shown in the attached figure. Figure 11 As shown; when contact point 21 contacts contact point 22, the pill is about to completely dissolve. When the external circuit is connected, the limiting plate 251 and limiting plate 252 will move to the position shown in the attached diagram under the push of the telescopic end of the electric telescopic rod 24. Figure 12 As shown, the feed chute 26 engages with the lowest pill in the delivery tube 15, causing the lowest pill to fall into the temporary storage ring 17. The second limiting plate 252 then limits the second-to-last pill, preventing it from falling. When the temporary storage ring 17 contains another pill, it moves the pull rod 20 and contact point 21 away from contact point 22. This means the external circuit controls the electric telescopic rod 24 to return the first limiting plate 251 and the second limiting plate 252 to their initial positions, as shown in the attached diagram. Figure 11 At the position shown, the limiting plate 251 limits the bottommost pill, thus facilitating the delivery of the pills one by one. This not only facilitates the treatment of wastewater but also prevents the waste of pill raw materials.

[0054] It should be further noted that, with reference to the appendix... Figure 5As shown, since multiple drug storage chambers 13 are designed and located behind different filter plates 3, different types of pills, such as activated carbon adsorbents and chemical reducing agents, can be put into the drug storage chambers 13. This allows for the gradual treatment of wastewater and improves the wastewater treatment effect.

[0055] During operation, wastewater generated in agricultural engineering is connected to the end of treatment pipe 2 through an external inlet pipe. Then, the wastewater is blocked by multiple filter plates 3 inside treatment pipe 2, which perform preliminary treatment, facilitating subsequent wastewater treatment. Furthermore, the scraper 301 moves from top to bottom along the front face of the filter plate 3, effectively scraping away larger impurities adhering to the front face of the filter plate 3. This prevents larger impurities such as plastic and other leaves from clogging the filter holes of the filter plate 3, thus avoiding problems with wastewater passing through the filter plate 3 surface. It also facilitates the centralized treatment of impurities blocked on the surface of the filter plate 3. After the filter plate 3 performs preliminary treatment, the wastewater flows to one side of the rotating shaft 4. Because the outer circumference of the rotating shaft 4 is equipped with multiple sets of blades 5, the rotating shaft 4 rotates at a certain speed under the impact of the water flow. This, in turn, drives the scraper 301 to move up and down through the linkage unit, allowing the wastewater to simultaneously scrape away impurities adhering to the front face of the filter plate 3 during the flow process, making operation convenient.

[0056] When the rotating shaft 4 rotates, it simultaneously drives the connecting shaft 6 to rotate. The connecting shaft 6, through the belt 8, drives the horizontal shaft 7 to rotate. The horizontal shaft 7 drives the limiting protrusion 10 connected to it to rotate. During the rotation, the protruding surface of the limiting protrusion 10 contacts the top of the pressure column 9, and the pressure column 9 moves downward under pressure. Therefore, the scraper 301 automatically processes the impurities adhering to the front surface of the filter plate 3, saving time and effort and avoiding the problem of excessive impurities adhering to the front surface of the filter plate 3 affecting the flow of wastewater. When the connecting shaft... When the connecting shaft 6 rotates with the rotating shaft 4, the connecting shaft 6 will drive the incomplete helical gear 201 to rotate through the driven unit. The incomplete helical gear 201 will drive the rack 14 meshing with it to move. The rack 14 will drive the drug delivery tube 15 and the drug storage chamber 13 to move through the bracket. That is, the drug storage chamber 13 will move left and right in the wastewater. Moreover, multiple sets of drug storage chambers 13 are set up, which can make the pills inside the drug storage chamber 13 evenly dispersed in the wastewater, so that the dispersed drug liquid can maximize the combination with the wastewater and improve the wastewater treatment effect.

[0057] See attached document Figure 6 and Figure 11As shown, when the storage chamber 13 is located inside the treatment pipe 2, the treatment pellets inside it are located within the temporary storage ring 17. As the storage chamber 13 moves left and right, wastewater combines with the treatment pellets through the grooves on the surface of the storage chamber 13 and gradually dissolves in the wastewater as the storage chamber 13 moves. When the treatment pellets are inside the temporary storage ring 17, the temporary storage ring 17 is subjected to pressure, which drives the pull rod 20 to move downward and pulls the tension spring 19. This facilitates the immersion of the treatment pellets in the wastewater, and they move with the movement of the storage chamber 13. When the temporary storage ring 17 drives the pull rod... When the lever 20 moves down and pulls the tension spring 19, the lever 20 will drive the contact 21 away from the contact 22. As the pill dissolves in the wastewater, the tension spring 19 will gradually drive the lever 20 and the temporary storage ring 17 to move up. That is, the lever 20 will gradually drive the contact 21 to move up. When the contact 21 contacts the contact 22, the pill is about to completely dissolve and the external circuit is connected. The external controller will control the electric telescopic rod 24 to move, so that the telescopic end of the electric telescopic rod 24 drives the limit frame 25 to move, and the pills are delivered one by one into the temporary storage ring 17.

[0058] When contact point 21 and contact point 22 are not in contact, that is, when the pill has not completely dissolved, the positions of limiting plate 251 and limiting plate 252 are as shown in the attached figure. Figure 11 As shown; when contact point 21 contacts contact point 22, the pill is about to completely dissolve. When the external circuit is connected, the limiting plate 251 and limiting plate 252 will move to the position shown in the attached diagram under the push of the telescopic end of the electric telescopic rod 24. Figure 12 As shown, the feed chute 26 engages with the lowest pill in the delivery tube 15, causing the lowest pill to fall into the temporary storage ring 17. The second limiting plate 252 then limits the second-to-last pill, preventing it from falling. When the temporary storage ring 17 contains another pill, it moves the pull rod 20 and contact point 21 away from contact point 22. This means the external circuit controls the electric telescopic rod 24 to return the first limiting plate 251 and the second limiting plate 252 to their initial positions, as shown in the attached diagram. Figure 11 At the position shown, the limiting plate 251 limits the bottommost pill, thus facilitating the delivery of the pills one by one. This not only facilitates the treatment of wastewater but also prevents the waste of pill raw materials.
