Description

Technical Field

[0001] This utility model relates to the field of plant slurry processing technology, specifically a three-roll milling device for processing plant slurry. Background Technology

[0002] Plant slurries are typically processed using a three-roll mill. Three-roll mills are suitable for manufacturing slurries in chemical production. The working principle of a three-roll mill is to achieve the grinding effect by the mutual extrusion and friction at different speeds of the surfaces of three horizontal rollers.

[0003] Conventional three-roll mills mostly require manual feeding by operators, which can easily lead to problems such as product overflow due to excessively fast feeding or low feeding speed and low grinding efficiency. At the same time, during the grinding process, operators need to monitor the feeding speed of the controller in real time, resulting in high product grinding and processing costs for enterprises. Operators also need to hold the material tank for a long time, which is labor-intensive. After grinding, the surface needs to be cleaned. Traditional three-roll mills can only be cleaned by hand, which is time-consuming and labor-intensive. Therefore, we propose a three-roll mill for processing plant slurry. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a three-roll mill for processing plant slurry. This not only keeps the feeding speed within a reasonable range, but also avoids the problems of product overflow due to excessive feeding speed or low grinding efficiency due to excessively slow feeding speed. This effectively solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-roll mill for processing plant slurry, comprising a three-roll mill;

[0006] The three-roll mill has connecting plates symmetrically installed at both ends of the right side, and a rectangular frame is provided between the connecting plates. The rectangular frame is fixedly connected to the fixed seat, and the fixed seat is fixedly connected to the connecting plate through a fixed rod. A material cylinder is rotatably connected inside the rectangular frame through a connecting shaft. The right connecting plate is provided with a rotating handle, and the left connecting plate is provided with a driven wheel and a driving wheel. A feed hopper is installed at the right end of the three-roll mill. Slide rails are symmetrically installed at the upper ends of the front and rear sides of the three-roll mill, and a water tank is provided above the slide rails.

[0007] The outer end of the left connecting plate is rotatably connected to a driven wheel and a driving wheel, which are connected by a belt. The lower inner side of the left connecting plate is fixedly mounted with a drive motor. The output shaft of the drive motor passes through the connecting plate and is fixedly connected to the driving wheel. The upper rotating shaft of the left connecting plate passes through the connecting plate and is fixedly connected to the driven wheel. The other end of the rotating shaft passes through the fixed seat and the rectangular frame and is fixedly connected to the connecting shaft. Fixed blocks are symmetrically mounted on the upper inner side of the rectangular frame. A connecting block is hinged inside the fixed block and fixedly connected to the material cylinder. The input end of the drive motor is electrically connected to the output end of the external controller.

[0008] When the feeding speed needs to be adjusted, the drive motor rotates the drive wheel, which in turn drives the material cylinder inside the rectangular frame to start rotating.

[0009] By controlling the angle of the feed cylinder, the feeding speed of the target equipment can be controlled, keeping it within a reasonable range. This prevents problems such as product overflow due to excessive feeding or low grinding efficiency due to excessively slow feeding. The process is highly automated, requires no manual operation, improves processing efficiency, and reduces processing costs for enterprises.

[0010] Furthermore, the rotating handle is fixedly connected to the threaded rod, the threaded rod is threadedly connected to the connecting plate, and the threaded rod passes through the connecting plate and is fixedly connected to the fixing plate, with the fixing plate in close contact with the outer end of the rectangular frame.

[0011] By turning the handle, the threaded rod can be rotated inside the connecting plate, and the tightness of the clamping of the barrel can be controlled. It can effectively lift and clamp the barrel instead of the operator. The overall operation is simple and greatly reduces the labor intensity of the workers.

[0012] Furthermore, one end of the feed hopper is sequentially equipped with infrared sensor one and infrared sensor two. Both infrared sensor one and infrared sensor two are fixedly connected to the inner wall of the three-roll mill. The output ends of infrared sensor one and infrared sensor two are electrically connected to the output end of an external controller.

[0013] When infrared sensor 1 detects product at the upper limit of the feed height, it indicates that the feeding device is feeding too fast, posing a risk of product overflowing the grinding and mixing equipment. When infrared sensor 1 does not detect product, but infrared sensor 2 detects product at the lower limit of the feed height, it indicates that the current feeding speed is normal. When infrared sensor 2 does not detect product, it indicates that the current feeding speed is too slow, and the tilt angle of the feed cylinder can be appropriately increased to accelerate the feeding speed.

[0014] Furthermore, each slide rail is slidably connected to a U-shaped slider, and a movable plate is fixedly connected to the outside of the U-shaped slider. The outside of the movable plate is fixedly connected to the output shaft of the cylinder. The cylinder is fixed to the upper end of the three-roll mill through a mounting base, and the air pump input end of the cylinder is electrically connected to the output end of an external controller.

[0015] An external controller activates the cylinder, which pushes the moving plate and in turn moves the U-shaped slider on the slide rail. The U-shaped slider can move horizontally on the slide rail, facilitating a thorough cleaning of the roller surface.

[0016] Furthermore, a hydraulic cylinder is fixedly installed at the upper end of each U-shaped slider. The output end of the hydraulic cylinder is fixedly connected to the lifting plate, the lifting plate is fixedly connected to both ends of the water tank, and the hydraulic pump input end of the hydraulic cylinder is electrically connected to the output end of the external controller.

[0017] The hydraulic cylinder is activated, which moves the lifting plate upwards, and in turn moves the box upwards or downwards. The three rollers on the three-roll mill can be cleaned by the nozzles when cleaning is needed. When cleaning is not needed, the nozzles will not contact the rollers and will not affect the operation of the rollers, thus achieving the purpose of cleaning the rollers.

[0018] Furthermore, mounting plates are fixedly installed on both sides of the lower end of the water tank, and a water storage pipe is fixedly connected between the mounting plates. The water tank is connected to the water storage pipe through a delivery hose. The lower end of the water storage pipe is connected to a nozzle. One end of the water tank is connected to a liquid replenishment pipe, and a water valve is installed on the liquid replenishment pipe.

[0019] Clean water is sprayed from the nozzle through the water storage pipe, making it easy to clean the surface of the roller without the need for manual cleaning, saving time and effort.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This three-roll milling equipment for processing plant slurry has the following advantages:

[0021] 1. By controlling the angle of the feed cylinder, the feed speed of the target equipment can be controlled, keeping it within a reasonable range. This prevents problems such as product overflow due to excessively fast feed or low grinding efficiency due to excessively slow feed. It has a high degree of automation, requires no manual operation, improves processing efficiency, and reduces processing costs for enterprises.

[0022] 2. By turning the handle, the threaded rod can be rotated inside the connecting plate, and the tightness of the clamping of the material cylinder can be controlled. It can effectively lift and clamp the material cylinder instead of the operator. The overall operation is simple and greatly reduces the labor intensity of the workers.

[0023] 3. The external controller starts the cylinder, which pushes the moving plate, thereby driving the U-shaped slider to move on the slide rail. The U-shaped slider can move horizontally on the slide rail, which facilitates the comprehensive cleaning of the roller surface. Attached Figure Description

Detailed Implementation

[0030] 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 protection scope of the present utility model.

[0031] Please see Figure 1-5 This embodiment provides a technical solution: a three-roll mill for processing plant slurry, including a three-roll mill 1;

[0032] The three-roll mill 1 has three grinding rollers rotatably installed inside. The three rollers are driven to rotate and grind by a power mechanism. Connecting plates 2 are symmetrically installed at both ends of the right side of the three-roll mill 1. A rectangular frame 6 is provided between the connecting plates 2. The rectangular frame 6 is fixedly connected to the fixed seat 12. The fixed seat 12 is fixedly connected to the connecting plate 2 through a fixed rod 14. A material cylinder 7 is rotatably connected inside the rectangular frame 6 through a connecting shaft 9. The right connecting plate 2 is provided with a rotating handle 3. The left connecting plate 2 is provided with a driven wheel 15 and a driving wheel 17. A feed hopper 19 is installed at the right end of the three-roll mill 1. Slide rails 25 are symmetrically installed at the upper ends of the front and rear sides of the three-roll mill 1. A water tank 28 is provided above the slide rails 25.

[0033] The outer end of the left connecting plate 2 is rotatably connected to a driven wheel 15 and a driving wheel 17. The driven wheel 15 and the driving wheel 17 are rotatably connected by a belt 16. The inner side of the lower end of the left connecting plate 2 is fixedly installed with a drive motor 18. The output shaft of the drive motor 18 passes through the connecting plate 2 and is fixedly connected to the driving wheel 17. The upper end of the left connecting plate 2 has a rotating shaft 13 that passes through the connecting plate 2 and is fixedly connected to the driven wheel 15. The other end of the rotating shaft 13 passes through the fixed seat 12 and the rectangular frame 6 and is fixedly connected to the connecting shaft 9. The upper inner side of the rectangular frame 6 has a fixed block 10 symmetrically installed. The fixed block 10 has a connecting block 11 hinged inside. The connecting block 11 is fixedly connected to the material cylinder 7. The input end of the drive motor 18 is electrically connected to the output end of the external controller.

[0034] When the feeding speed needs to be adjusted, the drive motor 18 drives the drive wheel 17 to rotate, which in turn drives the material cylinder 7 inside the rectangular frame 6 to start rotating.

[0035] By controlling the angle of the feed cylinder 7, the feeding speed of the target equipment can be controlled, keeping it within a reasonable range. This prevents problems such as product overflow due to excessive feeding or low grinding efficiency due to excessively slow feeding. The system is highly automated, requires no manual operation, improves processing efficiency, and reduces processing costs for enterprises.

[0036] The rotating handle 3 is fixedly connected to the threaded rod 4, the threaded rod 4 is threadedly connected to the connecting plate 2, and the threaded rod 4 passes through the connecting plate 2 and is fixedly connected to the fixing plate 5. The fixing plate 5 is in close contact with the outer end of the rectangular frame 6.

[0037] By turning the handle 3, the threaded rod 4 can be driven to rotate inside the connecting plate 2, and the tightness of the clamping of the material cylinder 7 can be controlled. It can effectively lift and clamp the material cylinder 7 instead of the operator. The overall operation is simple and greatly reduces the labor intensity of the workers.

[0038] Infrared sensor 120 and infrared sensor 21 are sequentially provided at one end of the feed hopper 19. Both infrared sensor 120 and infrared sensor 21 are fixedly connected to the inner wall of the three-roll mill 1. The output ends of infrared sensor 120 and infrared sensor 21 are electrically connected to the output end of an external controller.

[0039] When infrared sensor 20 detects product at the upper limit of the feed height, it indicates that the feeding device is feeding too fast, posing a risk of product overflowing the grinding and mixing equipment. When infrared sensor 20 does not detect product, but infrared sensor 21 detects product at the lower limit of the feed height, it indicates that the current feeding speed is normal. When infrared sensor 21 does not detect product, it indicates that the current feeding speed is too slow, and the tilt angle of the feed cylinder 7 can be appropriately increased to accelerate the feeding speed.

[0040] U-shaped sliders 26 are slidably connected to each slide rail 25. A movable plate 24 is fixedly connected to the outside of the U-shaped slider 26. The outside of the movable plate 24 is fixedly connected to the output shaft of the cylinder 23. The cylinder 23 is fixed to the upper end of the three-roll mill 1 through the mounting base 22. The air pump input end of the cylinder 23 is electrically connected to the output end of the external controller.

[0041] The external controller starts the cylinder 23, which pushes the moving plate 24, thereby driving the U-shaped slider 26 to move on the slide rail 25. The U-shaped slider 26 can move horizontally on the slide rail 25, which facilitates the comprehensive cleaning of the roller surface.

[0042] Hydraulic cylinders 35 are fixedly installed on the upper end of the U-shaped slider 26. The output end of the hydraulic cylinder 35 is fixedly connected to the lifting plate 34. The lifting plate 34 is fixedly connected to both ends of the water tank 28. The hydraulic pump input end of the hydraulic cylinder 35 is electrically connected to the output end of the external controller.

[0043] Start the hydraulic cylinder 35, which moves the lifting plate 34 upward, and in turn moves the box 28 upward or downward. The three rollers on the three-roll mill 1 can be cleaned by the nozzle 30 when they need to be cleaned. When they do not need to be cleaned, the nozzle 30 will not contact the rollers and will not affect the operation of the rollers, thus achieving the purpose of cleaning the rollers.

[0044] Mounting plates 27 are fixedly installed on both sides of the lower end of the water tank 28. A water storage pipe 29 is fixedly connected between the mounting plates 27. The water tank 28 is connected to the water storage pipe 29 through a delivery hose 31. A nozzle 30 is connected to the lower end of the water storage pipe 29. A liquid replenishment pipe 32 is connected to one end of the water tank 28. A water valve 33 is installed on the liquid replenishment pipe 32.

[0045] Clean water is sprayed from the nozzle 30 through the water storage pipe 29, which facilitates cleaning of the roller surface without the need for manual cleaning, saving time and effort.

[0046] The working principle of the three-roll mill for processing plant slurry provided by this utility model is as follows: When the feeding speed needs to be adjusted, the drive motor 18 drives the drive wheel 17 to rotate, which in turn drives the material cylinder 7 in the rectangular frame 6 to start rotating. By controlling the angle of the material cylinder 7, the feeding speed of the target equipment is controlled, so that the feeding speed is kept within a reasonable range. There will be no problem of product overflow due to excessive feeding or low grinding efficiency due to excessive feeding speed. The degree of automation is high, no manual operation is required, the processing efficiency is improved, and the processing cost of enterprises is reduced. Turning the handle 3 can drive the threaded rod 4 to rotate in the connecting plate 2, and can also control the tightness of clamping the material cylinder 7. It can replace the operator to lift and clamp the material cylinder 7 well. The overall operation is simple and greatly reduces the labor intensity of the workers. When the infrared sensor 20 detects that there is a product being fed at the upper limit of the feeding height, it indicates that the feeding device is feeding too fast, and there is a risk of product overflowing from the grinding and mixing equipment. When infrared sensor 20 does not detect the product being fed, while infrared sensor 21 detects the product at the lower limit of the feeding height, it indicates that the current feeding speed is normal. When infrared sensor 21 does not detect the product being fed, it indicates that the current feeding speed is too slow. The tilt angle of the material cylinder 7 can be increased appropriately to speed up the feeding speed. The cylinder 23 is activated, which pushes the moving plate 24, thereby driving the U-shaped slider 26 to move on the slide rail 25. The U-shaped slider 26 can move horizontally on the slide rail 25, facilitating a comprehensive cleaning of the roller surface. The hydraulic cylinder 35 moves the lifting plate 34 upward, thereby moving the box 28 upward or downward. The three rollers on the three-roll mill 1 can be cleaned by the nozzle 30 when cleaning is needed. When cleaning is not needed, the nozzle 30 will not contact the rollers and will not affect the operation of the rollers, thus achieving the purpose of cleaning the rollers. Clean water is sprayed out from the nozzle 30 through the water storage pipe 29, which facilitates the cleaning of the roller surface without the need for manual cleaning, saving time and effort.
