Description

Technical Field

[0001] This utility model relates to the technical field of vibrating screens for producing precipitated powder, specifically a vibrating screen for producing precipitated powder with stable operation. Background Technology

[0002] The vibrating screen for precipitated powder production is a vibrating screening device specially used in the precipitation process of starch, flour, chemical powder and other products. Its core function is to dehumidify and screen wet or dry precipitated powder, and it is a key machine for improving product quality and production efficiency.

[0003] In existing technologies, after the vibrating screen completes the starch screening, clumps of starch often remain on the screen. These clumps cannot be broken up and pass through the screen during the screening process, so they need to be collected and broken up manually. During the manual collection and breaking up of the starch clumps remaining on the screen, the starch is exposed to the outside air and is very easy to come into contact with and grow bacteria in the air, which leads to the starch deteriorating or declining in quality. Utility Model Content

[0004] The purpose of this invention is to provide a stable vibrating screen for the production of precipitated powder, which solves the problem that after the existing vibrating screen completes the starch screening, starch clumps often remain on the screen, and these clumps cannot be broken up and pass through the screen during the screening process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a vibrating screen for producing stable sedimentation powder, comprising a screening box, a cover plate mounted on the upper surface of the screening box, a drying structure mounted on the upper surface of the cover plate, a feed hopper mounted on one side of the screening box, an mounting plate mounted on the inner surface of the screening box, a spring and a lifting assembly mounted on the upper surface of the mounting plate, a partition plate mounted on the other end of the spring, a screen mounted on the upper surface of the partition plate, a connecting shaft rotatably connected to the inner surface of the screening box, a plurality of cams mounted on the outer surface of the connecting shaft, the cams being located at the lower end of the partition plate, a first motor mounted on the upper surface of the cover plate, a connecting rod mounted on the output end of the first motor via a coupling, a connecting plate mounted on the lower end of the connecting rod, an installation groove formed on the lower surface of the connecting plate, and a brush mounted inside the installation groove.

[0007] Furthermore, one end of the connecting shaft passes through the screening box and is equipped with a driven wheel. A second motor is provided at one end of the screening box, and a driving wheel is installed at the output end of the second motor. The driving wheel is connected to the driven wheel via a belt.

[0008] Furthermore, both ends of the partition plate are provided with inclined surfaces, which are located at both ends of the screen. The upper surface of the partition plate is provided with several through holes, which are located at the lower end of the screen.

[0009] Furthermore, the lower surface of the partition plate is provided with a housing, and the cam is located inside the housing.

[0010] Furthermore, the lifting assembly includes a rectangular block with a groove on its upper surface. A bidirectional screw is rotatably connected to the inner surface of the groove. Two sliders are threadedly connected to the outer surface of the bidirectional screw. A support rod is hinged to the upper surface of the slider, and a support plate is hinged to the upper surface of the support rod. One end of the bidirectional screw passes through the screening box and is equipped with a handle.

[0011] Furthermore, one end of the screening box has an opening, a collection box is installed inside the opening, and a handle is installed on the outer surface of the collection box.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] Please see Figures 1-4 As shown, this utility model is a vibrating screen for producing stable sedimentation powder, including a screening box 1, a cover plate 2 installed on the upper surface of the screening box 1, a drying structure 3 installed on the upper surface of the cover plate 2, a feed hopper 4 installed on one side of the screening box 1, an mounting plate 5 installed on the inner surface of the screening box 1, a spring 6 and a lifting assembly 7 installed on the upper surface of the mounting plate 5, a partition plate 8 installed at the other end of the spring 6, a screen 9 installed on the upper surface of the partition plate 8, a connecting shaft 10 rotatably connected to the inner surface of the screening box 1, a plurality of cams 11 installed on the outer surface of the connecting shaft 10, the cams 11 being located at the lower end of the partition plate 8, a first motor 12 installed on the upper surface of the cover plate 2, a connecting rod 13 installed at the output end of the first motor 12 via a coupling, a connecting plate 14 installed at the lower end of the connecting rod 13, an installation groove opened on the lower surface of the connecting plate 14, and a brush 15 installed inside the installation groove;

[0025] After the lifting assembly 7 lifts the partition plate 8 and the screen 9 to the working area of ​​the brush 15, the first motor 12 is started to drive the brush 15 to rotate at high speed. The brush 15 applies shearing force and kneading action to the starch clumps on the surface of the screen 9, which can effectively break up the clumps and break them into fine particles that can be sieved, thus avoiding the problem of starch clumps remaining on the screen 9.

[0026] The drying structure 3 includes a shell, a heating wire is installed at one end of the shell, a drive motor is installed inside the shell, and a fan blade is installed at the output end of the drive motor, with the fan blade located above the heating wire.

[0027] One end of the connecting shaft 10 passes through the screening box 1 and is equipped with a driven wheel 16. One end of the screening box 1 is equipped with a second motor 17. The output end of the second motor 17 is equipped with a driving wheel 18. The driving wheel 18 is connected to the driven wheel 16 via a belt 19.

[0028] Both ends of the partition plate 8 are provided with inclined surfaces, which are located at both ends of the screen 9. Several through holes are provided on the upper surface of the partition plate 8, which are located at the lower end of the screen 9.

[0029] The lower surface of the partition plate 8 is provided with a housing 801, and the cam 11 is located inside the housing 801;

[0030] The lifting assembly 7 includes a rectangular block 701. A groove is provided on the upper surface of the rectangular block 701. A bidirectional screw 702 is rotatably connected to the inner surface of the groove. Two sliders 703 are threadedly connected to the outer surface of the bidirectional screw 702. A support rod 704 is hinged to the upper surface of the slider 703. A support plate 705 is hinged to the upper surface of the support rod 704. One end of the bidirectional screw 702 passes through the screening box 1 and is equipped with a handle 706.

[0031] The screening box 1 has an opening at one end, and a collection box 20 is installed inside the opening. A handle 21 is installed on the outer surface of the collection box 20.

[0032] In use, wet or dry starch to be screened is fed into the screening box 1 through the feed hopper 4, allowing it to fall onto the upper surface of the separator plate 8. When wet starch is fed, the drying structure 3 is activated to dry and dehumidify the wet starch on the separator plate 8. After dehumidification, the drying structure 3 is closed, and the second motor 17 is started, causing its output to drive the drive wheel 18 to rotate. The drive wheel 18 drives the driven wheel 16 and the connecting shaft 10 to rotate via the belt 19. When the connecting shaft 10 rotates, the cam 11 mounted on the connecting shaft 10 moves with the shaft. When the cam 11 rotates together with the cam 11, its outer contour will periodically contact the lower surface of the separator 8 during the rotation. When the protruding part of the cam 11 contacts the separator 8, it will push the separator 8 upward and gradually stretch the spring 6. When the protruding part of the cam 11 leaves the separator 8, the spring 6 releases its elastic potential energy and pulls the separator 8 downward to reset. Under the combined action of the cam 11 and the spring 6, the separator 8 moves up and down reciprocally, forming vibration, so that the starch flows into the interior of the outer shell 801 after being screened by the screen 9, and then falls into the collection box 20 for centralized collection.

[0033] When there is a large amount of clumps of starch on the separator plate 8, the handle 706 is turned, causing the double-ended screw 702 to rotate. The outer surface of the double-ended screw 702 has opposite threads at both ends and is threadedly connected to two sliders 703 respectively. When the double-ended screw 702 rotates, the two sliders 703 will move towards or away from each other along the screw axis. When the two sliders 703 move towards each other, the support rod 704 pushes the support plate 705 upward, thereby lifting the separator plate 8 and raising it. At the same time, the spring 6 is fully stretched, lifting the separator plate 8 and the screen 9 upward to the working area of ​​the brush 15. Then, the first motor 12 is started, driving the brush 15 to rotate at high speed. The brush 15 applies shearing force and kneading action to the clumps of starch on the surface of the screen 9, which can effectively break up the clumps and break them into fine particles that can be sieved. Then, the first motor 12 is turned off, and the handle 706 is turned in the opposite direction, so that the support plate 705 cancels the support of the separator plate 8. At the same time, the spring 6 restores its elasticity and pulls the separator plate 8 to reset.
