Description

Technical Field

[0001] This utility model relates to the field of weeding machine production technology, specifically a sedimentation device for herbicide production. Background Technology

[0002] Herbicides are pesticides that cause weeds to die completely or selectively; they are also known as herbicides and are substances used to kill or inhibit plant growth. Sedimentation devices can remove suspended particles, impurities, and unreacted raw materials from the herbicide concentrate, resulting in a purer herbicide product.

[0003] The settling device is designed with a settling space inside. After the herbicide concentrate and flocculant are mixed, they are introduced into the settling space. Under static or very slow flow conditions, due to gravity, the solid particles suspended in the liquid will gradually sink, while the clear liquid will remain on the upper layer.

[0004] In the process of herbicide production, raw materials often contain various impurities. These impurities are prone to deposit inside the device during the settling process, especially in key parts such as drainage pipes and collection pipes. After long-term accumulation, these deposited impurities may cause pipe blockage and affect the normal operation of the device. Therefore, a settling device for herbicide production is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, it is important to note that raw materials often contain various impurities during herbicide production. These impurities tend to accumulate inside the equipment during sedimentation, particularly in critical areas such as drainage pipes and collection pipes. Over time, these accumulated impurities can cause pipe blockages, affecting the normal operation of the equipment. This invention proposes a sedimentation device for herbicide production.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A sedimentation device for herbicide production, comprising a sedimentation tank; a water inlet pipe is fixedly connected to one side of the lower end of the sedimentation tank, and a drain pipe is fixedly connected to the other side of the upper end; a collection pipe is fixedly installed at the bottom of the sedimentation tank; a stirring shaft is provided inside the sedimentation tank, the lower end of which extends into the collection pipe and is rotatably installed at the bottom of the collection pipe; a feeding screw is welded to the outer periphery of the upper end of the stirring shaft located in the collection pipe; an extrusion plate is provided below the feeding screw and slidably installed inside the collection pipe; a passage is opened in the center of the extrusion plate. The extrusion plate is slidably mounted on the stirring shaft through the through hole. A filter screen is fixedly installed inside one end of the drain pipe connected to the settling tank. A brush is provided on the side of the filter screen away from the settling tank and rotates inside the drain pipe. A connecting shaft is fixedly installed on one side of the brush, and the other end of the connecting shaft is rotated inside the drain pipe and passes through the drain pipe. Through the synergistic action of components such as the stirring shaft, feeding screw, extrusion plate, filter screen and brush, effective sedimentation of liquid and efficient discharge of impurities are achieved during the herbicide production process. At the same time, the continuous unobstructed flow of the filter screen is ensured, thereby improving the quality and efficiency of herbicide production.

[0007] Preferably, multiple stirring rods are fixedly mounted in an array on the stirring shaft, and a scraper is fixedly mounted at the end of each stirring rod. By setting stirring rods and scrapers on the stirring shaft, not only is the sedimentation efficiency improved, but also the deposition of impurities inside the device and the blockage of the pipes are effectively prevented, ensuring the normal operation of the device.

[0008] Preferably, a mounting base is fixedly installed at the outer corner of the drain pipe, and a rotary motor is fixedly installed on the mounting base. The rotating shaft of the rotary motor is fixedly connected to the connecting shaft. The installation of the rotary motor enables the brush to rotate and clean automatically, further preventing the drain pipe from getting clogged and improving the reliability and stability of the device.

[0009] Preferably, a spring is fixedly installed at the bottom of the extrusion plate, and the lower end of the spring is fixedly installed at the bottom of the collecting pipe. The spring is also fully fitted onto the lower end of the stirring shaft. The introduction of the spring allows the extrusion plate to better adapt to solid particles of different sizes, improving the extrusion effect. At the same time, it ensures the rapid reset of the extrusion plate, preparing it for the next extrusion.

[0010] Preferably, a drive motor is fixedly installed at the bottom of the collecting pipe, and the rotating shaft of the drive motor is fixedly connected to the lower end of the stirring shaft. The configuration of the drive motor ensures the rotation speed and stability of the stirring shaft, further improving the settling efficiency, and also provides a stable power source for the operation of the feeding screw and the extrusion plate.

[0011] Preferably, a discharge pipe is provided below one side of the extrusion plate. The discharge pipe is fixedly connected to the lower end of the collection pipe. The addition of the discharge pipe allows the extruded solid particles to be smoothly discharged from the device, facilitating subsequent collection and processing, and improving the practicality and convenience of the device.

[0012] The advantages of this utility model are:

[0013] 1. This utility model, during the sedimentation process of herbicide production, introduces the herbicide concentrate into the sedimentation tank through an inlet pipe. A drive motor starts, rotating the stirring shaft. The rotation of the stirring shaft causes the stirring rod and scraper to agitate and scrape the concentrate. Simultaneously, a feeding screw conveys the solid particles deposited in the collection pipe downwards. A pressing plate, under the action of a spring, squeezes the solid particles, discharging the liquid. The squeezed solid particles are discharged through a discharge pipe. During drainage, a filter screen intercepts small solid particles flowing out with the liquid. Simultaneously, a rotating motor starts, driving a brush to rotate and clean impurities from the filter screen surface, preventing clogging. This structural design achieves efficient sedimentation and prevents clogging, solving the problem that raw materials often contain various impurities during herbicide production. These impurities easily accumulate inside the device during sedimentation, especially in critical areas such as the drainage and collection pipes. Over time, these accumulated impurities can cause pipe blockage, affecting the normal operation of the device. This invention improves the cleanliness and operating efficiency of the device, reducing downtime maintenance costs and production interruption risks caused by pipe blockage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 As shown, a settling device for herbicide production includes a settling tank 1; a water inlet pipe 2 is fixedly connected to one side of the lower end of the settling tank 1, and a drain pipe 3 is fixedly connected to the other side of the upper end; a collection pipe 4 is fixedly installed at the bottom of the settling tank 1; a stirring shaft 5 is installed inside the settling tank 1, with its lower end extending into the collection pipe 4 and rotatably installed at the bottom of the collection pipe 4; a feeding screw 8 is welded to the outer periphery of the upper part of the stirring shaft 5 located in the collection pipe 4; a pressing plate 9 is slidably installed inside the collection pipe 4 below the feeding screw 8; a through hole is opened in the center of the pressing plate 9, and the pressing plate 9 is slidably installed on the stirring shaft 5 through the through hole; a filter screen 13 is fixedly installed in one end of the drain pipe 3 connected to the settling tank 1; a brush is provided on the side of the filter screen 13 away from the settling tank 1. The brush 15 is rotatably installed inside the drain pipe 3. A connecting shaft 14 is fixedly installed on one side of the brush 15, and the other end of the connecting shaft 14 is rotatably installed inside the drain pipe 3 and passes through the drain pipe 3. During operation, in the herbicide production sedimentation process, the herbicide concentrate is introduced into the sedimentation tank 1 through the water inlet pipe 2. At this time, the drive motor 12 starts and drives the stirring shaft 5 to rotate. The stirring rod 6 and scraper 7 on the stirring shaft 5 stir the concentrate and scrape off the adhering substances on the tank wall and the inner wall of the collection pipe 4 to prevent the deposition of impurities. As the stirring shaft 5 rotates, the feeding screw 8 conveys the solid particles deposited in the collection pipe 4 downward to the extrusion plate 9. The extrusion plate 9 extrudes the solid particles under the action of the spring 10 and discharges the liquid. The extruded solid particles are discharged through the discharge pipe 11. During the drainage process, the filter screen 13 intercepts the fine solid particles flowing out with the liquid to ensure the purity of the discharged liquid. At the same time, the rotary motor 17 starts and drives the brush 15 to rotate and clean the impurities on the surface of the filter screen 13 to prevent the filter screen 13 from clogging.

[0023] Multiple stirring rods 6 are fixedly mounted in an array on the stirring shaft 5, and each stirring rod 6 has a scraper 7 fixedly mounted at its end. During operation, in the herbicide production and settling process, the stirring shaft 5 rotates, causing the stirring rods 6 and scrapers 7 to rotate simultaneously. The synergistic effect of the stirring rods 6 and scrapers 7 allows the solid particles in the herbicide liquid to settle more quickly, while keeping the settling tank 1 clean.

[0024] A mounting base 16 is fixedly installed at the outer corner of the drain pipe 3. A rotary motor 17 is fixedly installed on the mounting base 16. The rotating shaft of the rotary motor 17 is fixedly connected to the connecting shaft 14. During operation, in the sedimentation process of herbicide production, the rotary motor 17 is started, and its rotating shaft drives the connecting shaft 14 to rotate. The connecting shaft 14 drives the brush 15 to rotate. When the clear liquid is discharged through the drain pipe 3, the rotation of the brush 15 can clean the fine solid particles attached to the surface of the filter screen 13, preventing the filter screen 13 from clogging. This not only ensures the unobstructed flow of the drain pipe 3, but also ensures the purity of the discharged liquid.

[0025] A spring 10 is fixedly installed at the bottom of the extrusion plate 9. The lower end of the spring 10 is fixedly installed at the bottom of the collection pipe 4, and the spring 10 is entirely fitted onto the lower end of the stirring shaft 5. During operation, as the solid particles continuously settle in the collection pipe 4 during the herbicide production sedimentation process, the pressure on the extrusion plate 9 gradually increases. The elasticity of the spring 10 allows the extrusion plate 9 to undergo a certain displacement under pressure, thus fitting more tightly onto the solid particles. When the stirring shaft 5 rotates, the feeding screw 8 conveys the solid particles downward to the extrusion plate 9, which then extrudes the solid particles and discharges the liquid. The elastic restoring force of the spring 10 allows the extrusion plate 9 to quickly return to its original position after extrusion, preparing for the next extrusion.

[0026] A drive motor 12 is fixedly installed at the bottom of the collection pipe 4, and the rotating shaft of the drive motor 12 is fixedly connected to the lower end of the stirring shaft 5. During operation, in the sedimentation process of herbicide production, the drive motor 12 starts and drives the stirring shaft 5 to rotate. The rotation of the stirring shaft 5 not only enables the stirring rod 6 and scraper 7 to work normally, but also conveys the solid particles in the collection pipe 4 downward through the feeding screw 8. In addition, the rotation of the stirring shaft 5 also generates centrifugal force, which helps to separate the liquid in the solid particles and improve the sedimentation efficiency.

[0027] A discharge pipe 11 is provided below one side of the extrusion plate 9. The discharge pipe 11 is fixedly connected to the lower end of the collection pipe 4. During operation, in the sedimentation process of herbicide production, the solid particles after extrusion are discharged through the discharge pipe 11. Due to the action of the extrusion plate 9, most of the liquid in the solid particles has been discharged, so the discharged solid particles are relatively dry and easy to process. The setting of the discharge pipe 11 makes the discharge of solid particles smoother and avoids the problems of blockage and accumulation.

[0028] Working principle: During the sedimentation process of herbicide production, the herbicide concentrate is introduced into the sedimentation tank 1 through the inlet pipe 2. At this time, the drive motor 12 starts, driving the stirring shaft 5 to rotate. The stirring rod 6 and scraper 7 on the stirring shaft 5 stir the concentrate and scrape off the adhering substances on the tank wall and the inner wall of the collection pipe 4 to prevent the deposition of impurities. As the stirring shaft 5 rotates, the feeding screw 8 conveys the solid particles deposited in the collection pipe 4 downward to the extrusion plate 9. The extrusion plate 9 extrudes the solid particles under the action of the spring 10, discharging the liquid. The extruded solid particles are discharged through the discharge pipe 11. During the drainage process, the filter screen 13 intercepts the fine solid particles flowing out with the liquid to ensure the purity of the discharged liquid. At the same time, the rotary motor 17 starts, driving the brush 15 to rotate and clean the impurities on the surface of the filter screen 13 to prevent the filter screen 13 from clogging.
