Description

Technical Field

[0001] This utility model belongs to the field of potassium sorbate granule production technology, and in particular, a potassium sorbate granule screening device. Background Technology

[0002] After potassium sorbate powder is granulated, it needs to be screened using a screening device. In order to prevent the screen from being blocked, the existing screening device often uses a brush or other structure for cleaning. However, the cleaning part is blocked, which reduces the screening area of ​​the screen for potassium sorbate particles and reduces the screening effect of the screening device for potassium sorbate particles.

[0003] In related technologies, a search revealed a Chinese patent document (authorization announcement number CN221208870U) for a potassium sorbate particle screening device, which includes a support frame. A second rotary motor is fixed to the top of the support frame, and a first connecting bracket is fixed to the output shaft of the second rotary motor. A second connecting bracket is hinged to the bottom of the first connecting bracket, and a screen frame is fixed to the bottom of the second connecting bracket. A disc is rotatably mounted on the first connecting bracket, and a transmission bar is fixed on the second connecting bracket. A sliding opening is provided on the transmission bar, and a lever is fixed to the side of the disc near the transmission bar. The lever passes through the sliding opening and through the transmission bar. When the second rotary motor is turned on, it drives the first connecting bracket to rotate, which in turn drives the second connecting bracket and the screen frame to rotate. This causes the screen frame to swing due to inertia, accelerating the screening of potassium sorbate particles. It also causes the screen frame to shake, which improves the fluidity of the potassium sorbate particles during screening and further improves the screening efficiency. The aforementioned patent does not consider that the cleaning part of the screen may be blocked, resulting in a reduction in the screening area of ​​the screen for potassium sorbate particles and reducing the screening effect of the screening device on potassium sorbate particles. Utility Model Content

[0004] The purpose of this invention is to provide a potassium sorbate particle screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a potassium sorbate particle screening device, comprising: The screening box has two rotating disks embedded in its inner cavity. A screening screen for potassium sorbate particles is welded to the adjacent sides of the two rotating disks. The inner cavity of the screening screen is provided with several connecting rods for supporting the two rotating disks. The cleaning assembly includes a fixed frame and a rotating rod. The bottom surface of the fixed frame is welded to the screening box. The two inner side walls of the fixed frame are rotatably connected to the rotating rod through bearings. The inner bottom wall of the fixed frame is provided with a cleaning plate for cleaning the screening screen. The side of the cleaning plate is embedded and fixedly connected to the rotating rod. A driven pulley is welded to the end face of the rotating rod. A belt is provided on the side of the driven pulley. A drive pulley is provided on the inner wall of the belt.

[0006] Preferably, a rotary motor for driving the rotating disc is installed on the outer wall of the screening box, and a feeding pipe that penetrates the side wall of the screening box is embedded and fixedly connected to the side of the rotating disc.

[0007] Preferably, the side of the drive pulley is fixedly connected to the inside of the feeding pipe, and the inner cavity of the screening box is provided with an inclined plate.

[0008] Preferably, a horizontal plate is welded to the side of the inclined plate, and the inner wall of the screening box is slidably connected to the horizontal plate.

[0009] Preferably, a connecting plate is welded to the top surface of the horizontal plate, and a connecting frame is provided on the upper part of the horizontal plate.

[0010] Preferably, the inner cavity of the connecting frame is provided with a pulley and a reciprocating screw, and the end face of the reciprocating screw is welded to the pulley.

[0011] Preferably, the side of the connecting plate is threaded to the reciprocating lead screw, and a second belt is provided on the side of the pulley.

[0012] Preferably, the inner wall of the second belt is provided with a second pulley, and a connecting shaft is welded to the side of the second pulley, with the end face of the connecting shaft welded to the rotating rod.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This potassium sorbate particle screening device allows the circular screening screen to screen potassium sorbate particles. Thanks to the design of the cleaning component, when cleaning the surface of the screening screen, the part of the screen that screens potassium sorbate particles is not blocked, thereby improving the screening effect of the device. The rotary motor provides power, and the screening screen rotates during the transmission process. With the connection of the feeding pipe, the driving pulley, belt one, and the driven pulley, the cleaning plate rotates around the rotating rod as the axis, realizing the surface cleaning of the screening screen, preventing the screening screen from clogging, and at the same time not blocking the screening of potassium sorbate particles, thus improving the screening efficiency of the device. The potassium sorbate particle screening device, with the connection of pulley one, pulley two, and belt two, allows the connecting plate to move along the thread path of the reciprocating screw in the inner cavity of the connecting frame. During the transmission process, the horizontal plate and the inclined plate move, so that the inclined plate pushes the potassium sorbate particles after screening, which facilitates the potassium sorbate particles to leave the screening box and provides conditions for the next step of processing. This potassium sorbate particle screening device uses a single rotary motor to power multiple functional structures, eliminating the need for multiple motors, reducing energy consumption, and improving the environmental friendliness of the device.

[0018] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0019] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0020] Please see Figures 1 to 5 A potassium sorbate particle screening device, in this embodiment including: The screening box 1 has two rotating disks 2 embedded in its inner cavity. The rotating disks 2 are located on two opposite sides of the screening box 1, and the adjacent sides of the two rotating disks 2 are flush with the two inner sides of the screening box 1. A screening mesh 3 for potassium sorbate particle screening is welded to the adjacent sides of the two rotating disks 2. To prevent potassium sorbate particles from getting stuck in the weld gap, a fluororubber sealing gasket (1mm thick and 5mm wide) is attached to the weld between the screening mesh 3 and the rotating disk 2 to further improve the sealing performance and prevent fine particle leakage. The screening mesh 3 is cylindrical, and the inner cavity of the screening mesh 3 is provided with several connecting rods 4 for supporting the two rotating disks 2. The connecting rods 4 are arranged in a ring array, and both ends of the connecting rods 4 are welded to the two rotating disks 2. Sufficient space is reserved between the connecting rods 4 and the screening mesh 3 to prevent the screening mesh 3 from being blocked and affecting the screening of potassium sorbate particles. The cleaning component 5 includes a fixed frame 6 and a rotating rod 7. The bottom surface of the fixed frame 6 is welded to the screening box 1. The two inner side walls of the fixed frame 6 are rotatably connected to the rotating rod 7 via bearings. The inner bottom wall of the fixed frame 6 is provided with a cleaning plate 8 for cleaning the screening screen 3. The side of the cleaning plate 8 is embedded and fixedly connected to the rotating rod 7, and the rotating rod 7 passes through the cleaning plate 8. The cleaning plate 8 is roughly T-shaped, and the edges of the cleaning plate 8 are arc-shaped. The distance between the cleaning plate 8 and the screening screen 3 is adapted according to actual usage requirements, so that the cleaning plate 8 rotates around the rotating rod 7 as the axis. During the rotation process, the screening screen 3 is struck. The distance between the top surface of the cleaning plate 8 and the inner top surface of the fixed frame 6 is sufficient to prevent the cleaning plate 8 from scratching the fixed frame 6 and improve the structural stability of the components of the device. A driven pulley 9 is welded to the end face of the rotating rod 7. A belt 10 is provided on the side of the driven pulley 9. A driving pulley 11 is provided on the inner wall of the belt 10. Both the driving pulley 11 and the driven pulley 9 are located on the inner wall of the belt 10. The driving pulley 11 and the driven pulley 9 pull the belt 10 together, which provides the conditions for the synchronous and co-rotation of the driving pulley 11 and the driven pulley 9.

[0021] A rotary motor for driving the rotating disk 2 is installed on the outer wall of the screening box 1. The fixed end of the rotary motor is connected to a C-shaped bracket by bolts. The side of the bracket is welded to the screening box 1, so that there is a gap between the fixed end of the rotary motor and the screening box 1. A feeding pipe 12 that penetrates the side wall of the screening box 1 is embedded and fixedly connected to the side of the rotating disk 2. The side of the drive pulley 11 is embedded and fixedly connected to the feeding pipe 12. An inclined plate 13 is provided in the inner cavity of the screening box 1. The size of the inclined plate 13 is adapted to the inner cavity of the screening box 1. The side of the screening box 1 is provided with a discharge port for material discharge. The inner cavity size of the discharge port is sufficient so that the inclined plate 13 can extend out of the screening box 1 through the discharge port.

[0022] A horizontal plate 14 is welded to the side of the inclined plate 13. The inner wall of the screening box 1 is slidably connected to the horizontal plate 14. A connecting plate 15 is welded to the top surface of the horizontal plate 14. A connecting frame 16 is provided on the upper part of the horizontal plate 14. A pulley 18 and a reciprocating screw 17 are respectively provided in the inner cavity of the connecting frame 16. Rotating shafts are rotatably connected to both sides of the connecting frame 16 through bearings. The adjacent sides of the two rotating shafts are welded to the pulley 18 and the reciprocating screw 17 respectively. The end face of the reciprocating screw 17 is welded to the pulley 18. The connecting plate 15... 5. The side is threaded to the reciprocating lead screw 17. The side of the pulley 18 is provided with the belt 2 19. The inner wall of the belt 2 19 is provided with the pulley 2 20. The side of the pulley 2 20 is welded with the connecting shaft 21. The end face of the connecting shaft 21 is welded to the rotating rod 7. The pulley 18 and the pulley 2 20 are both located on the inner wall of the belt 2 19. The pulley 18 and the pulley 2 20 tighten the belt 2 19. Under the connection of the belt 2 19, the pulley 18 and the pulley 2 20 can rotate synchronously and in the same direction.

[0023] One of the rotating disks 2 has a drive shaft welded to its side. The end face of the drive shaft is connected to the output shaft of the rotary motor via a coupling. The other rotating disk 2 is connected to the feeding pipe 12. A sealing cover 22 is installed on the side of the rotating disk 2 connected to the feeding pipe 12. The sealing cover 22 is embedded in the rotating disk 2. The side of the sealing cover 22 near the screening box 1 is flush with the side of the rotating disk 2 near the screening box 1 to prevent the sealing cover 22 from affecting the rotation of the rotating disk 2. A disassembly groove is provided on the side of the screening box 1 near the discharge port for disassembling the sealing cover 22. When the rotating disk 2 rotates to the designated position, the sealing cover 22 can be disassembled through the disassembly groove to discharge the larger potassium sorbate particles screened in the screening screen 3.

[0024] In order to perform screening, potassium sorbate particles are fed into the inner cavity formed by the combination of screening screen 3 and two rotating disks 2 through feeding pipe 12, so that screening screen 3 can screen potassium sorbate particles. At the same time, several connecting rods 4 provide support and enhance the structural stability of screening screen 3 and two rotating disks 2. To perform cleaning, a rotary motor provides power, which causes the screening screen 3 to rotate during the transmission process. Simultaneously, with the connection of the driving pulley 11, belt 10, and driven pulley 9, the cleaning plate 8 can rotate around the rotating rod 7 as the axis, causing the cleaning plate 8 to knock and vibrate the surface of the screening screen 3, cleaning the potassium sorbate particles clogging the surface of the screening screen 3. At the same time, during the cleaning process, the part of the screening screen 3 that is not blocked from the potassium sorbate particles improves the screening efficiency of the device for potassium sorbate particles. In order to discharge the material, the connecting plate 15 can move along the threaded path of the reciprocating screw 17 through the connection of pulley 20, belt 2 19, and pulley 18. The two inner side walls of the connecting frame 16 are slidably connected to the connecting plate 15. During the transmission process, the horizontal plate 14 drives the inclined plate 13 to move, and pushes the screened potassium sorbate granules to speed up the discharge efficiency of the screened potassium sorbate granules.

[0025] A single rotary motor is used to drive the movement of multiple structures, eliminating the need for multiple motors, reducing energy consumption, and improving the environmental friendliness of the device. The connecting plate 15 has a threaded groove on its side that matches the thread of the reciprocating lead screw 17. The rotary motor is surrounded by a protective shell, and a filter screen is embedded and fixedly connected inside the protective shell, giving the rotary motor heat dissipation and dust resistance functions.

[0026] Rotary motors are conventional instruments, and their working principles, dimensions, and models are irrelevant to the functions of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0027] Working principle When using this potassium sorbate particle screening device, potassium sorbate particles are input into the inner cavity formed by the combination of screening screen 3 and two rotating disks 2. The rotating motor is started, so that the screening screen 3 screens the potassium sorbate particles during rotation. Under the connection of the driving pulley 11, belt 10 and driven pulley 9, the cleaning plate 8 rotates around the rotating rod 7 as the axis. The cleaning plate 8 knocks on the screening screen 3 to clean the surface of the screening screen 3. With the connection of pulley 20, belt 2 19, and pulley 18, the connecting plate 15 moves along the thread path of the reciprocating screw 17 within the inner cavity of the connecting frame 16, causing the horizontal plate 14 to drive the inclined plate 13 to reciprocate, pushing the screened potassium sorbate granules and accelerating the feeding rate.
