Description

Technical Field

[0001] The utility model relates to the field of chemical powders, in particular to an anti-clogging vibrating screen for impurity removal of chemical powders. Background Art

[0002] Chemical powders refer to various powdery raw materials or products used in the chemical industry. They are widely used in the manufacturing processes of plastics, coatings, pharmaceuticals, catalysts, fertilizers, explosives, and numerous other chemical products.

[0003] A device for processing chemical powders with the patent authorization announcement number CN210304440U includes a stainless steel sieve frame. Inside the sieve frame, an upper sieve mesh, a pot-shaped lower sieve mesh, and a funnel-shaped aggregate hopper are sequentially arranged from top to bottom. Among them, an arc-shaped arching part arches upward in the middle of the upper sieve mesh. A discharge pipe is arranged at the middle of the bottom of the lower sieve mesh. A protective cylinder sleeving on the discharge pipe is arranged at the bottom of the lower sieve mesh. The protective cylinder is directly above the minimum opening end of the aggregate hopper, and the lower sieve mesh inside the protective cylinder is a solid structure. A cover plate is arranged at the opening at the top of the sieve frame. Among them, a feed port facing the arching part is arranged on the cover plate, and a discharge port in the same vertical plane as the inner side wall of the sieve frame is also arranged on one side of the cover plate. Depressions are arranged on both sides of the outer side wall of the sieve frame. Among them, a cross bar is arranged in the depression. A U-shaped notch is also arranged at the bottom end of the side wall of the sieve frame. When screening chemical powders, the above patent performs hierarchical screening of chemical powders through two layers of sieve meshes. However, during the long-term screening of chemical powders, the phenomenon of powder adhesion and deposition may occur. Since the sieve frame is integrally arranged, if the powder adhered to the sieve holes is not cleaned in time, these adhered powders are likely to block the sieve holes, thereby reducing the screening efficiency of chemical powders.

[0004] In view of the above-mentioned patent currently existing, an anti-clogging vibrating screen for impurity removal of chemical powders with a rotatable mounting frame is required. Summary of the Utility Model

[0005] In order to overcome the drawback that if the powder adhered to the sieve holes is not cleaned in time, these adhered powders are likely to block the sieve holes, the utility model provides an anti-clogging vibrating screen for impurity removal of chemical powders.

[0006] The technical solution of the present utility model is as follows: An anti-blocking vibrating screen for chemical powder impurity removal, comprising a machine frame, a rotating shaft, a mounting frame, a fixing rod, a sieve plate, a vibrator, a spring and a baffle. The two sides of the upper part of the machine frame are symmetrically and rotatably connected with the rotating shafts. Both rotating shafts penetrate the machine frame. An installation frame is arranged between the two rotating shafts. A group of fixing rods are arranged on both inner sides of the installation frame. The two fixing rods in the same group are arranged at intervals up and down. A sieve plate is slidably arranged inside the installation frame. The sieve plate is located between the upper and lower fixing rods. Springs are arranged between the fixing rods and the sieve plate. A vibrator is installed on each of the upper surface and the lower surface of the sieve plate. The two vibrators are arranged in opposite directions. Baffles are symmetrically connected to the left and right inside the installation frame, and two rectangular grooves are provided on the baffles.

[0007] As a further preferred solution, it further comprises a motor. The motor is installed on the front side of the machine frame, and the output shaft of the motor is connected to the front rotating shaft.

[0008] As a further preferred solution, it further comprises a collection box and a cover plate. Two collection boxes are arranged on the sides of the two baffles away from each other. The two collection boxes on the same side are respectively located above and below the sieve plate. The two rectangular grooves respectively correspond to the two collection boxes in the same group. A cover plate is rotatably connected to the collection box, and the diameter of the cover plate is adapted to the diameter of the opening of the collection box.

[0009] As a further preferred solution, it further comprises a mounting plate, a plug pin and an elastic member. The two sides of the upper part of the machine frame are symmetrically connected with mounting plates. The two mounting plates on the same side are located outside the rotating shafts. A plug pin is slidably connected to the middle of the mounting plate, and an elastic member is arranged between the plug pin and the mounting plate.

[0010] As a further preferred solution, grooves adapted to the plug pins are provided on both sides of the rotating shaft.

[0011] As a further preferred solution, the collection box is designed in a conical shape.

[0012] Compared with the prior art, the present utility model has the following advantages: By pulling the installation frame and rotating it clockwise by 180 degrees, all the components inside it can be driven to rotate, and at the same time, the two rotating shafts are driven to rotate along the machine frame, which is convenient for manually completing the overall flipping of the installation frame, so that the blocked side of the sieve plate is flipped to the lower side. During the next screening process of chemical powder, the agglomerated powder blocking the sieve holes will fall under the action of the vibration of the sieve plate. This process can dredge the blocked sieve holes, thereby preventing the sieve holes of the sieve plate from being blocked and affecting the screening efficiency of chemical powder.

Detailed implementation manners

[0020] The present utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which the currently preferred embodiments of the present utility model are shown. However, the present utility model can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present utility model to those skilled in the art.

[0021] Example: An anti-clogging vibrating sieve for chemical powder impurity removal, as Figures 1 - 6As shown in the figure, it includes a machine frame 1, a rotating shaft 111, a mounting frame 2, a fixing rod 3, a sieve plate 4, a vibrator 41, a spring 5, a baffle 6, a collection box 7, a cover plate 8, a motor 9, a mounting plate 10, a bolt 11 and an elastic member 12. The upper part of the machine frame 1 is symmetrically and rotatably connected with the rotating shaft 111 at the front and rear. The two rotating shafts 111 penetrate through the machine frame 1. A mounting frame 2 is arranged between the two rotating shafts 111. A set of fixing rods 3 are arranged on both inner sides of the mounting frame 2. The two fixing rods 3 in the same group are arranged at intervals up and down. A sieve plate 4 is slidably arranged inside the mounting frame 2. When the sieve plate 4 is in a vibrating state, chemical powder can be screened to achieve the rapid separation of chemical powder and impurities. The sieve plate 4 is located between the fixing rods 3 on the upper and lower sides. Springs 5 are arranged between the fixing rods 3 and the sieve plate 4. When the sieve plate 4 is not in a vibrating state, the springs 5 can drive the sieve plate 4 to reset, so that the sieve plate 4 returns to its initial position. A vibrator 41 is installed on each of the upper surface and the lower surface of the sieve plate 4. The two vibrators 41 are arranged in opposite directions, so that the vibrations generated by the two vibrators 41 cancel each other out in the vertical direction, reducing unnecessary vertical movement and making the sieve plate 4 vibrate mainly in the horizontal direction. The superimposed vibration in the horizontal direction helps the chemical powder to pass through the sieve holes more easily, improving the flow rate and uniformity of the chemical powder during the screening process. Baffles 6 are symmetrically connected to the left and right inside the mounting frame 2. Two rectangular grooves are provided on the baffles 6. Two collection boxes 7 are arranged on the sides of the two baffles 6 away from each other. The collection boxes 7 are designed in a conical shape, making it easy for the chemical powder to slide down and facilitating the staff to take out the chemical powder from the collection boxes 7 after screening. The two collection boxes 7 on the same side are respectively located on the upper and lower sides of the sieve plate 4. The two rectangular grooves respectively correspond to the two collection boxes 7 in the same group. A cover plate 8 is rotatably connected to the collection box 7. The diameter of the cover plate 8 is adapted to the diameter of the opening of the collection box 7, effectively preventing the chemical powder from splashing during screening. A motor 9 is installed on the front side of the machine frame 1. The output shaft of the motor 9 is connected to the front rotating shaft 111. Mounting plates 10 are symmetrically connected to both sides of the upper part of the machine frame 1. The two mounting plates 10 on the same side are located outside the rotating shaft 111. A bolt 11 is slidably connected to the middle of the mounting plate 10. An elastic member 12 is arranged between the bolt 11 and the mounting plate 10. In this embodiment, the elastic member 12 is a spring. Grooves adapted to the bolt 11 are provided on the upper and lower sides of the rotating shaft 111. When the bolt 11 is in a fixed state, it is inserted into the groove to fix the rotating shaft 111.

[0022] When the device needs to be used and the staff needs to remove impurities from chemical powder, the staff pulls the cover plate 8 to rotate and open it. Then, the chemical powder to be purified is poured onto the sieve plate 4. When a certain amount of chemical powder is poured, the staff pulls the cover plate 8 to rotate in the reverse direction until the cover plate 8 covers the opening of the collection box 7 and is placed inside the opening, and then the cover plate 8 is released. The staff starts the vibrator 41, and the vibrator 41 generates vibration through the centrifugal force generated by the eccentric wheel. The sieve plate 4 starts to vibrate under the action of the vibration, and the spring 5 deforms accordingly. Since the two vibrators 41 are arranged in the opposite direction, the vibrations they generate will cancel each other out in the vertical direction and be superimposed in the horizontal direction, forming a linear vibration mode. This vibration mode helps the chemical powder to quickly fall through the sieve holes into the installation frame 2, while the impurities will remain on the sieve plate 4. When the screening of the chemical powder is completed and the screened chemical powder and impurities need to be collected, the staff pulls the bolt 11 to move outward along the mounting plate 10, and the elastic member 12 is stretched. Repeat the above operation to make the remaining bolts 11 in the pulled state. Then, start the motor 9. The output shaft of the motor 9 drives the rotating shaft 111 to rotate. The rotating shaft 111 drives the installation frame 2 and all the components inside it to rotate, and then drives another rotating shaft 111 to rotate. When the installation frame 2 rotates to the preset inclination angle, turn off the motor 9. The screened chemical powder slides down into the collection box 7 inside at the inclined angle of the installation frame 2, and at the same time, the impurities also slide down into the corresponding collection box 7 inside. Then, the staff places the storage box under the upper collection box 7, and then pulls the upper cover plate 8 to rotate and open it, so that the impurities slide into the storage box through the upper collection box 7, which is convenient for collecting the impurities. When the collection of the impurities is completed, pull the upper cover plate 8 to rotate in the reverse direction until the upper cover plate 8 covers the opening of the corresponding collection box 7 and is placed inside the opening, and then release the upper cover plate 8. Then, the staff places the stock box under the lower collection box 7, and then pulls the lower cover plate 8 to rotate and open it, so that the screened chemical powder slides into the stock box through the lower collection box 7, which is convenient for collecting the chemical powder. When the collection of the chemical powder is completed, pull the lower cover plate 8 to rotate in the reverse direction until the cover plate 8 covers the opening of the collection box 7 and is placed inside the opening, and then release the lower cover plate 8. During the long-term screening process of the chemical powder, there may be a phenomenon of powder adhesion and deposition. These adhered chemical powders are likely to block the sieve holes. Then, the staff starts the motor 9 again. The output shaft of the motor 9 drives the rotating shaft 111 to rotate again. The rotating shaft 111 drives the installation frame 2 and all the components inside it to rotate, and then drives another rotating shaft 111 to rotate. When the installation frame 2 rotates clockwise by 180 degrees, at this time, the bolt 11 is aligned with the groove on the rotating shaft 111 again. Then, release the bolt 11. Under the reset action of the elastic member 12, the bolt 11 moves inward along the mounting plate 10 until the bolt 11 moves to the initial position and is inserted into the groove, which is convenient for fixing the rotating shaft 111. Repeat the operation of releasing the bolt 11,The remaining bolts 11 are all moved to the initial positions. At this time, the blocked side of the sieve plate 4 is flipped downward. During the next chemical powder screening process, the chemical powder adhering and blocking in the sieve holes will fall off under the vibration of the sieve plate 4, so that the blocked sieve holes are dredged, preventing the sieve holes of the sieve plate 4 from being blocked and affecting the screening efficiency of the chemical powder. Repeat the above operations. When the chemical powder impurity removal operation is completed, the vibrator 41 and the motor 9 are turned off. Due to the shutdown of the vibrator 41, the sieve plate 4 is no longer in a vibrating state. At this time, under the reset action of the spring 5, the sieve plate 4 returns to the initial position.,

[0023] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the implementation scope of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.,
