Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment, and specifically relates to a wastewater treatment device for agricultural engineering. Background Art

[0002] Agricultural engineering wastewater mainly comes from agricultural production activities such as crop cultivation, livestock breeding, and agricultural product processing. Its composition is complex, containing a large amount of organic matter, suspended solids, phosphorus nutrients, and pesticide residues and other pollutants. If these wastewaters are directly discharged without treatment, they will cause serious pollution to water bodies, soil, and the ecological environment, and even threaten human health.

[0003] Some solutions have also been proposed in the prior art for the treatment of agricultural engineering wastewater. For example, a Chinese patent application with the publication number CN208265902U discloses an agricultural wastewater treatment device, including a bottom plate. Both sides of the bottom of the bottom plate are fixedly connected with columns. The left side of the top of the bottom plate is fixedly connected with a disinfection tank. The left side of the top of the disinfection tank is provided with a medicine adding port. The center of the top of the disinfection tank is fixedly connected with a motor. The above technical solution realizes the advantage of good filtration effect, solves the problem of poor filtration effect of the existing agricultural wastewater treatment device, enables the pesticide wastewater to be recycled or safely discharged, and improves the practicability of the agricultural wastewater treatment device.

[0004] Although the above technical solution solves the problem of poor filtration effect of the existing agricultural wastewater treatment device, there are still other problems in actual use, such as the problem that the filter plate often affects the flow of wastewater due to excessive impurities adhering to its surface during long-term filtration, which is not conducive to the treatment of agricultural engineering wastewater.

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

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A wastewater treatment device for agricultural engineering according to the present invention includes a treatment base. A treatment pipeline is installed above the treatment base. The treatment pipeline is connected to an external water inlet pipeline. A plurality of filter plates are installed inside the treatment pipeline. The plurality of filter plates are designed to be separated from each other. The filter plates are used to block impurities in the wastewater. A scraper is provided on the front end face of each filter plate. The scraper can move up and down 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, a rotating shaft is rotatably arranged inside the processing pipeline. A plurality of rotating shafts are provided and are located behind the filter plate. A plurality of groups of paddle blades are fixedly installed on the outer peripheral surface of the rotating shaft. The rotating shafts are connected by a first belt. The end of one of the rotating shafts is connected to the output end of an externally connected driving motor. A rotational speed sensor is arranged at the end of the rotating shaft. A linkage unit is arranged at the end of the rotating shaft, and the linkage unit is used to drive the scraper to move. During operation, after the filter plate preliminarily treats the wastewater, the wastewater will flow to one side of the rotating shaft. Since a plurality of groups of paddle blades are arranged on the outer peripheral surface of the rotating shaft, under the impact of the water flow, the rotating shaft will rotate at a certain speed. Then, through the action of the linkage unit, the scraper is driven to move up and down, so that when the wastewater flows through, the impurities adhered to the front end face of the filter plate are synchronously scraped off, and the operation is relatively convenient.

[0009] Preferably, the linkage unit includes a connecting shaft fixedly installed at the end of the rotating shaft. A horizontal shaft is rotatably arranged above the processing pipeline. The end of the horizontal shaft is connected to the end of the connecting shaft by a second belt. A pressing column is installed above the scraper. The top end of the pressing column is slidably arranged inside the processing pipeline. A limiting convex block is fixedly installed on the outer peripheral surface of the horizontal shaft, and the convex surface of the limiting convex block contacts the top end of the pressing column.

[0010] Preferably, a limiting groove adapted to the pressing column is arranged inside the processing pipeline, and the pressing column is slidably arranged inside the limiting groove through a support rod. A limiting spring is fixedly connected to the groove wall of the limiting groove. The end of the limiting spring away from the limiting groove is connected to the support rod on the side wall of the pressing column. The distance that the limiting convex block presses down the pressing column is greater than the diameter of the filter plate. During operation, when the pressing column moves downward, the support rod on its side wall will drive the pressing column to move downward along the limiting groove and compress the limiting spring on the groove wall of the limiting groove. When the convex end of the limiting convex block is far away from the top end of the pressing column, under the action of the limiting spring, the pressing column will move upward, so that the scraper will move upward to process the impurities on the filter plate again.

[0011] Preferably, a medicine storage cavity is arranged inside the processing pipeline. The medicine storage cavity can move left and right inside the processing pipeline. Purifying pills are stored inside the medicine storage cavity, and a plurality of holes are formed on the surface of the medicine storage cavity.

[0012] Preferably, a rack is slidably arranged above the processing pipeline. A medicine delivery pipe is installed above the medicine storage cavity. The side wall of the medicine delivery pipe is connected to the side wall of the rack through a bracket. An incomplete helical gear is rotatably arranged above the processing pipeline. The incomplete helical gear is meshed with the rack. A driven unit is arranged on the side of the incomplete helical gear. The connecting shaft drives the incomplete helical gear to rotate through the driven unit.

[0013] Preferably, the incomplete helical gear is rotatably arranged above the treatment pipeline through 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 third belt. During operation, when the connecting shaft rotates, the connecting shaft drives the rotating rod to rotate through the third belt, and the rotating rod drives the incomplete helical gear to rotate. Thus, the incomplete helical gear drives the rack to move, which facilitates driving the medicine storage cavity to move left and right.

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

[0015] Preferably, a first contact is installed on the side wall of the pull rod, a second contact is installed on the groove wall of the rectangular groove, a fixing frame is installed on the side wall of the medicine delivery pipe, an electric telescopic rod is installed on the surface of the fixing frame, a limiting frame is fixedly installed at the telescopic end of the electric telescopic rod, the limiting frame is slidably arranged inside the medicine delivery pipe, and the limiting frame is used to limit the treatment pills and convey the pills into the temporary storage ring one by one. During operation, when the temporary storage ring drives the pull rod to move downward and pulls the tension spring, the pull rod drives the first contact to move away from the second contact. As the pills dissolve in the waste water, the tension spring gradually drives the pull rod and the temporary storage ring to move upward, that is, the pull rod gradually drives the first contact to move upward. When the first contact contacts the second contact, the pills are about to be completely dissolved and the external circuit is connected. The external controller controls the electric telescopic rod to move, so that the telescopic end of the electric telescopic rod drives the limiting frame to move, and the pills are conveyed into the temporary storage ring one by one.

[0016] Preferably, a first limiting plate and a second limiting plate are installed on the surface of the limiting frame. The first limiting plate and the second limiting plate are designed to be separated up and down. A material-passing groove is formed on the surface of the first limiting plate.

[0017] The beneficial effects of the present invention are as follows: 1. For the agricultural engineering waste water treatment device of the present invention, after the waste water is preliminarily treated by the filter plate, the waste water will flow to one side of the rotating shaft. Since a plurality of paddle blades are arranged on the outer peripheral surface of the rotating shaft, under the impact of the water flow, the rotating shaft will rotate at a certain speed. Then, under the action of the linkage unit, the scraper is driven to move up and down, so that during the flow of the waste water, the impurities adhered to the front surface of the filter plate are simultaneously scraped off, and the operation is relatively convenient.

[0018] 2. The agricultural engineering wastewater treatment device described in the present invention drives the rack meshed with it to move through an incomplete helical gear.

DETAILED DESCRIPTION OF THE INVENTION

[0022] In order to make the technical means, creative features, achieved objectives and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] As Figures 1 to 6 shown, a wastewater treatment device for agricultural engineering according to an embodiment of the present invention includes a treatment base 1. Above the treatment base 1, a treatment pipeline 2 is installed. The treatment pipeline 2 is connected to an external water inlet pipeline. Inside the treatment pipeline 2, a plurality of filter plates 3 are installed. The plurality of filter plates 3 are designed to be separated from each other. The filter plates 3 are used to block impurities in the wastewater. On the front end face of each filter plate 3, a scraper 301 is provided. 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. During operation, the wastewater generated in agricultural engineering is connected to the end of the treatment pipeline 2 through an external water inlet pipe. Then, under the blockage of the plurality of filter plates 3 inside the treatment pipeline 2, larger impurities in the wastewater can be blocked and preliminarily treated, which facilitates the subsequent treatment of the wastewater. Moreover, under the action of the scraper 301, it can move from top to bottom along the front end face of the filter plate 3, which is beneficial to scraping off the larger impurities adhering to the front end face of the filter plate 3, avoiding the problem that larger impurities such as plastics and other leaves block the filter holes of the filter plate 3 and affect the passage of wastewater through the surface of the filter plate 3, and is also beneficial to the subsequent centralized treatment of the impurities blocked on the surface of the filter plate 3. It should be noted that the front end face of the filter plate 3 is the water inlet direction of the wastewater, and a plurality of filter plates 3 are provided to achieve a multiple treatment effect.

[0024] Inside the treatment pipeline 2, a rotating shaft 4 is rotatably provided. A plurality of rotating shafts 4 are provided and are located behind the filter plates 3. On the outer peripheral surface of the rotating shaft 4, multiple groups of paddle blades 5 are fixedly installed. The rotating shafts 4 are connected by a first belt. The end of one of the rotating shafts 4 is connected to the output end of an external driving motor. A rotational speed sensor is provided at the end of the rotating shaft 4. A linkage unit is provided at the end of the rotating shaft 4. The linkage unit is used to drive the scraper 301 to move. During operation, after the filter plates 3 preliminarily treat the wastewater, the wastewater will flow to one side of the rotating shaft 4. Since multiple groups of paddle blades 5 are provided on the outer peripheral surface of the rotating shaft 4, under the impact of the water flow, the rotating shaft 4 will rotate at a certain speed. Then, under the action of the linkage unit, the scraper 301 is driven to move up and down, so that during the flow of the wastewater, the impurities adhering to the front end face of the filter plates 3 are simultaneously scraped off, and the operation is relatively convenient. It should be noted that a rotational speed sensor is provided at the end of the rotating shaft 4, and a minimum threshold is set for the rotational speed of the rotating shaft 4. When the rotational speed of the rotating shaft 4 is less than the minimum threshold, the rotational speed sensor will transmit a signal to the controller, causing the controller to control the external drive motor to drive the rotating shaft 4 to rotate, so as to ensure the up and down movement of the scraper 301 and improve the treatment efficiency of the wastewater.

[0025] As Figures 2 to 8 shown, the linkage unit includes a connecting shaft 6 fixedly installed at the end of the rotating shaft 4. A horizontal shaft 7 is rotatably arranged above the treatment pipeline 2. The end of the horizontal shaft 7 and the end of the connecting shaft 6 are connected by a second belt 8. A pressing column 9 is installed above the scraper 301. The top end of the pressing column 9 is slidably arranged inside the treatment pipeline 2. A limiting convex block 10 is fixedly installed on the outer peripheral surface of the horizontal shaft 7. The protruding surface of the limiting convex block 10 contacts the top end of the pressing column 9; During operation, when the rotating shaft 4 rotates, the rotating shaft 4 will drive the connecting shaft 6 to rotate at the same time. The connecting shaft 6 will drive the horizontal shaft 7 to rotate through the second belt 8. The horizontal shaft 7 drives the limiting convex block 10 connected to it to rotate. During the rotation of the limiting convex block 10, its protruding surface will contact the top end of the pressing column 9. Then, the pressing column 9 will move downward under the pressure, so the scraper 301 will automatically process the impurities adhered to the front end surface of the filter plate 3, saving time and effort and avoiding the problem that too many impurities adhered to the front end surface of the filter plate 3 affect the wastewater flow.

[0026] A limiting groove 11 adapted to the pressing column 9 is arranged inside the treatment pipeline 2. The pressing column 9 is slidably arranged inside the limiting groove 11 through a support rod. A limiting spring 12 is fixedly connected to the groove wall of the limiting groove 11. One end of the limiting spring 12 away from the limiting groove 11 is connected to the support rod on the side wall of the pressing column 9. The distance that the limiting convex block 10 presses down the pressing column 9 is greater than the diameter of the filter plate 3; During operation, when the pressing column 9 moves downward, the pressing column 9 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 convex block 10 is far away from the top end of the pressing column 9, under the action of the limiting spring 12, the pressing column 9 will move upward, so that the scraper 301 will move upward to process the impurities on the filter plate 3 again; It should be noted that the elastic restoring force of the limiting spring 12 and the pressure of the limiting convex block 10 on the pressing column 9 are both greater than the pressure of the wastewater impacting the scraper 301, so as to facilitate the up and down movement of the scraper 301.

[0027] As Figures 3 to 10 shown, a medicine storage cavity 13 is arranged inside the treatment pipeline 2. The medicine storage cavity 13 can move left and right inside the treatment pipeline 2. The medicine storage cavity 13 stores purification pills. A plurality of holes are arranged on the surface of the medicine storage cavity 13; During operation, refer to the appendixFigure 5 As shown, during the flow of wastewater, a plurality of medicine storage chambers 13 are provided, and the medicine storage chambers 13 move left and right inside the treatment pipeline 2. Thus, the purification pills inside will dissolve in the wastewater during the left and right movement, improving the uniform dispersion of the purification pills in the wastewater, that is, improving the treatment efficiency of the wastewater.

[0028] As Figures 3 to 12 As shown, a rack 14 is slidably provided above the treatment pipeline 2. A medicine delivery pipe 15 is installed above the medicine storage chamber 13. The side wall of the medicine delivery pipe 15 is connected to the side wall of the rack 14 through a bracket. An incomplete helical gear 201 is rotatably provided above the treatment pipeline 2. The incomplete helical gear 201 is meshed and connected with the rack 14; a driven unit is provided on the side of the incomplete helical gear 201. The connecting shaft 6 drives the incomplete helical gear 201 to rotate through the driven unit. During operation, when the connecting shaft 6 rotates following the rotating shaft 4, the connecting shaft 6 drives the incomplete helical gear 201 to rotate through the driven unit. The incomplete helical gear 201 drives the rack 14 meshed with it to move. The rack 14 drives the medicine delivery pipe 15 and the medicine storage chamber 13 to move through the bracket, that is, the medicine storage chamber 13 moves left and right in the wastewater. Moreover, a plurality of groups of medicine storage chambers 13 are provided, enabling the pills inside the medicine storage chamber 13 to be uniformly dispersed in the wastewater, maximizing the combination of the dispersed liquid medicine with the wastewater, and improving the treatment effect of the wastewater.

[0029] The incomplete helical gear 201 is rotatably provided above the treatment pipeline 2 through 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 third belt; during operation, when the connecting shaft 6 rotates, the connecting shaft 6 drives the rotating rod 16 to rotate through the third belt. The rotating rod 16 drives the incomplete helical gear 201 to rotate, so that the incomplete helical gear 201 drives the rack 14 to move, thus facilitating the left and right movement of the medicine storage chamber 13.

[0030] It should be noted that, as Figure 7 shown, the rack 14 is slidably provided above the treatment pipeline 2 through 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 and the rack 14 are not meshed and the spring is in a stretched state, the spring force can drive the rack 14 to move, thus facilitating the left and right movement of the rack 14.

[0031] Inside the medicine storage cavity 13, a temporary storage ring 17 is provided. On the inner wall of the medicine delivery pipe 15, rectangular grooves 18 are symmetrically arranged. On the groove wall of the rectangular groove 18, a tension spring 19 is fixedly installed. At the bottom of the tension spring 19, a pull rod 20 is fixedly installed. The bottom of the pull rod 20 is connected to the side wall of the temporary storage ring 17. The pull rod 20 is slidably arranged inside the rectangular groove 18. During operation, refer to the attached Figure 6 and Figure 11 As shown, when the medicine storage cavity 13 is inside the treatment pipeline 2, the treatment pills inside it will be located in the temporary storage ring 17. As the medicine storage cavity 13 moves left and right, the wastewater combines with the treatment pills through the hole grooves on the surface of the medicine storage cavity 13 and gradually dissolves in the wastewater following the movement of the medicine storage cavity 13. When the treatment pills are inside the temporary storage ring 17, the temporary storage ring 17 will be pressured by them and drive the pull rod 20 to move downward, and will pull the tension spring 19. In this way, it is convenient for the treatment pills to be immersed in the wastewater and move along with the movement of the medicine storage cavity 13; It should be noted that the weight of the pills is greater than the density of the wastewater, and the weight of the pills is much greater than the elastic potential energy of the tension spring 19. In this way, it is convenient for the pills to fall into the temporary storage ring 17.

[0032] On the side wall of the pull rod 20, a first contact 21 is installed. On the groove wall of the rectangular groove 18, a second contact 22 is installed. On the side wall of the medicine delivery pipe 15, a fixing frame 23 is installed. On the surface of the fixing frame 23, an electric telescopic rod 24 is installed. The telescopic end of the electric telescopic rod 24 is fixedly installed with a limiting frame 25. The limiting frame 25 is slidably arranged inside the medicine delivery pipe 15. The limiting frame 25 is used to limit the treatment pills and convey the pills into the temporary storage ring 17 one by one; During operation, when the temporary storage ring 17 drives the pull rod 20 to move downward and pulls the tension spring 19, the pull rod 20 will drive the first contact 21 to move away from the second contact 22. As the pills dissolve in the wastewater, the tension spring 19 will gradually drive the pull rod 20 and the temporary storage ring 17 to move upward, that is, the pull rod 20 will gradually drive the first contact 21 to move upward. When the first contact 21 contacts the second contact 22, at this time the pills are about to be completely dissolved, 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 limiting frame 25 to move, and conveys the pills into the temporary storage ring 17 one by one; It should be noted that the elastic potential energy of the tension spring 19 is greater than the gravity of the temporary storage ring 17, and the first contact 21 and the second contact 22 are not in contact with the wastewater.

[0033] A limiting plate 251 and a limiting plate 252 are mounted on the surface of the limiting frame 25. The limiting plate 251 and the limiting plate 252 are designed in an up-and-down separated manner. A material-passing groove 26 is formed on the surface of the limiting plate 251. During operation, when the first contact 21 and the second contact 22 are not in contact, that is, when the pill has not been completely dissolved, the positions of the limiting plate 251 and the limiting plate 252 are as shown in the appendix Figure 11 ; when the first contact 21 and the second contact 22 are in contact, at this time the pill is about to be completely dissolved and the external circuit is connected. Under the push of the telescopic end of the electric telescopic rod 24, the limiting plate 251 and the limiting plate 252 will move to the position as shown in the appendix Figure 12 ; that is, the material-passing groove 26 will be combined with the pill at the bottom of the medicine delivery pipe 15, so that the pill at the bottom will fall into the temporary storage ring 17, and the limiting plate 252 will limit the second-to-last pill to prevent it from falling; when there is again a pill in the temporary storage ring 17, it will drive the pull rod 20 and the first contact 21 away from the second contact 22, that is, the external circuit will control the electric telescopic rod 24 to drive the limiting plate 251 and the limiting plate 252 to return to the initial position, that is, the position as shown in the appendix Figure 11 ; at this time, the limiting plate 251 limits the pill at the bottom, so it is convenient to convey the pills one by one. In this way, it is not only convenient for the treatment of wastewater, but also does not waste the raw materials of the pills; Furthermore, it should be noted that, as shown in the appendix Figure 5 , since a plurality of medicine storage cavities 13 are designed and are located behind different filter plates 3, different types of pills can be placed in the medicine storage cavities 13, such as activated carbon adsorbents and chemical reducing agents, etc. In this way, the wastewater can be treated step by step, improving the treatment effect of the wastewater.

[0034] During operation, the wastewater generated in agricultural engineering is connected to the end of the treatment pipeline 2 through an external water inlet pipe. After that, under the blockage of a plurality of filter plates 3 inside the treatment pipeline 2, the larger impurities in the wastewater can be blocked and preliminarily treated, which is convenient for the subsequent treatment of the wastewater. Moreover, under the action of the scraper 301, it can move downwards along the front end surface of the filter plate 3 from top to bottom, which is conducive to scraping off the larger impurities adhering to the front end surface of the filter plate 3, avoiding the problem that larger impurities such as plastics and other leaves block the filter holes of the filter plate 3 and affect the passage of wastewater through the surface of the filter plate 3, and is also conducive to the subsequent centralized treatment of the impurities blocked on the surface of the filter plate 3; after the filter plate 3 preliminarily treats the wastewater, the wastewater will flow to one side of the rotating shaft 4. Since a plurality of sets of blades 5 are arranged on the outer peripheral surface of the rotating shaft 4, under the impact of the water flow, the rotating shaft 4 will rotate at a certain speed. Then, under the action of the linkage unit, the scraper 301 is driven to move up and down, so that when the wastewater flows through, the impurities adhering to the front end surface of the filter plate 3 are scraped off synchronously, and the operation is relatively convenient; When the rotating shaft 4 rotates, the rotating shaft 4 will drive the connecting shaft 6 to rotate simultaneously. The connecting shaft 6 will drive the horizontal shaft 7 to rotate through the second belt 8. The horizontal shaft 7 drives the limiting convex block 10 connected thereto to rotate. During the rotation of the limiting convex block 10, its convex surface will contact the top end of the pressing column 9. Furthermore, the pressing column 9 will move downward under the pressure, so the scraper 301 will automatically process the impurities adhering to the front end surface of the filter plate 3, saving time and effort and avoiding the problem that too many impurities adhere to the front end surface of the filter plate 3 and affect the wastewater flow. When the connecting shaft 6 rotates following 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 drives the rack 14 engaged therewith to move. The rack 14 will drive the medicine delivery pipe 15 and the medicine storage cavity 13 to move through the bracket, that is, the medicine storage cavity 13 will move left and right in the wastewater. Moreover, multiple groups of medicine storage cavities 13 are provided, which can make the pills inside the medicine storage cavity 13 disperse evenly in the wastewater, so that the dispersed liquid medicine can be maximally combined with the wastewater, improving the wastewater treatment effect; Refer to the attached Figure 6 and Figure 11 As shown, when the medicine storage cavity 13 is located inside the treatment pipeline 2, the treatment pills inside it will be located in the temporary storage ring 17. As the medicine storage cavity 13 moves left and right, the wastewater combines with the treatment pills through the holes on the surface of the medicine storage cavity 13 and gradually dissolves in the wastewater following the movement of the medicine storage cavity 13. When the treatment pill is inside the temporary storage ring 17, the temporary storage ring 17 will be under its pressure and drive the pull rod 20 to move downward, and will pull the tension spring 19. In this way, it is convenient for the treatment pill to immerse in the wastewater and move following the movement of the medicine storage cavity 13. When the temporary storage ring 17 drives the pull rod 20 to move downward and pulls the tension spring 19, the pull rod 20 will drive the contact point one 21 away from the contact point two 22. As the pill dissolves in the wastewater, the tension spring 19 will gradually drive the pull rod 20 and the temporary storage ring 17 to move upward, that is, the pull rod 20 will gradually drive the contact point one 21 to move upward. When the contact point one 21 contacts the contact point two 22, at this time the pill is about to be completely dissolved 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 limiting frame 25 to move, and the pills are individually delivered into the temporary storage ring 17; When the contact point one 21 and the contact point two 22 are not in contact, that is, when the pill has not been completely dissolved, the positions of the limiting plate one 251 and the limiting plate two 252 are as shown in the attached Figure 11 As shown; when the contact point one 21 contacts the contact point two 22, at this time the pill is about to be completely dissolved and the external circuit is connected. Under the push of the telescopic end of the electric telescopic rod 24, the limiting plate one 251 and the limiting plate two 252 will move to the position as shown in the attached Figure 12As shown, the material-passing trough 26 will combine with the pills at the bottom of the medicine delivery pipe 15, so that the pills at the bottom will fall into the temporary storage ring 17, and the second limiting plate 252 will limit the second-to-last pill to prevent it from falling; when there are pills in the temporary storage ring 17 again, it will drive the pull rod 20 and the first contact 21 away from the second contact 22, that is, the external circuit will control the electric telescopic rod 24 to drive the first limiting plate 251 and the second limiting plate 252 to return to the initial position, that is, as shown in the attached Figure 11 figure. At this time, the first limiting plate 251 limits the pills at the bottom, so it is convenient to convey the pills one by one. In this way, it is not only convenient for the treatment of wastewater, but also does not waste the raw materials of the pills.
