Description

Technical Field

[0001] This utility model relates to the field of high-frequency stacked vibrating screen technology, specifically a high-frequency stacked vibrating screen with a clean and anti-clogging screen. Background Technology

[0002] The stacked high-frequency vibrating fine screen consists of two electric vibrators moving in opposite directions, driving the screen frame in a linear motion. The resultant force of the two electric vibrators acting on the screen frame passes through the center of gravity of the screen frame. When transporting materials over and under the screen, the receiving plate that receives the materials tends to stick to them, resulting in the materials not being used in a timely manner after screening. Furthermore, when too much material accumulates on the receiving plate, it may affect the normal operation of the vibrating screen. In the existing technology, the presence of scraper plates, drive motors, drive shafts, moving gears, and moving racks can remove the materials adhering to the first and second discharge plates, thereby reducing the difficulty of material adhering to the first and second discharge plates and affecting the subsequent material screening process. However, the screen plates cannot be cleaned when screening materials, and the materials can clog the screen holes, reducing the screening efficiency of the high-frequency stacked vibrating screen.

[0003] Therefore, this utility model provides a high-frequency stacked vibrating screen with a clean and anti-clogging screen to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved This invention provides a high-frequency stacked vibrating screen with a clean and anti-clogging screen, aiming to solve the problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a high-frequency stacked vibrating screen with a clean and anti-clogging screen, comprising a support frame, a vibrating screen body fixedly installed on the top of the support frame, multiple screens installed inside the vibrating screen body, a cleaning device provided inside the vibrating screen body, a power device provided above the vibrating screen body, and a rinsing device provided on the left side of the vibrating screen body.

[0006] The cleaning device includes a bracket, which is fixedly installed on the top of the vibrating screen body. Connecting rods are slidably connected to the front and rear ends of the bracket. Connecting plates are fixedly installed at the opposite ends of the two connecting rods. Push rods are fixedly installed on the adjacent sides of the two connecting plates. Scrapers are fixedly installed at the end of the push rods away from the connecting plates. A rotating shaft is rotatably connected to the middle of the bracket. A gear is fixedly installed on the outer side of the lower end of the rotating shaft.

[0007] As a preferred technical solution of this application, the lower surface of the scraper is in contact with the upper surface of the screen, the outer side of the connecting rod is provided with a toothed groove, and the connecting rod can mesh with a gear. The gear is located between the left and right connecting rods. Rotating the shaft drives the gear to rotate and mesh with the connecting rod, thereby causing the connecting rod to drive the connecting plate and the push rod to move back and forth in a straight line, so that the scraper moves in a straight line to scrape off the material or impurities accumulated on the screen surface, thereby cleaning the screen.

[0008] As a preferred technical solution of this application, there are multiple screens and multiple push rods and scrapers, and multiple screens can be cleaned by multiple scrapers.

[0010] As a preferred technical solution of this application, a limiting groove is formed on the upper surface of the bracket, and the bottom of the rack is slidably connected in the limiting groove. The rack and the second gear mesh with each other. When the reciprocating screw and the slider are threadedly connected, the rack is driven to move back and forth in a linear motion through the slider. The meshing of the rack and the second gear causes the rotating shaft to rotate clockwise and counterclockwise.

[0011] As a preferred technical solution of this application, the rinsing device includes a water tank, which is fixedly installed on the top of the support frame on the left side of the vibrating screen body. A pump body is installed on the back of the water tank, and the output end of the pump body is connected to a main pipe.

[0016] 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.

[0017] This utility model provides a high-frequency stacked vibrating screen with a clean and anti-clogging screen, such as Figures 1-3 As shown, the high-frequency stacked vibrating screen with a clean and anti-clogging screen includes a support frame 1, a vibrating screen body 2 fixedly installed on the top of the support frame 1, multiple screens 3 installed inside the vibrating screen body 2, a cleaning device inside the vibrating screen body 2, a power device above the vibrating screen body 2, and a rinsing device on the left side of the vibrating screen body 2.

[0018] The cleaning device includes a bracket 4, which is fixedly installed on the top of the vibrating screen body 2. Connecting rods 5 are slidably connected at the front and rear ends inside the bracket 4. Connecting plates 6 are fixedly installed at the opposite ends of the two connecting rods 5. Push rods 7 are fixedly installed on the adjacent side of the two connecting plates 6. A sealing ring is installed at the connection between the push rod 7 and the vibrating screen body 2. The sealing ring seals the gap between the push rod 7 and the vibrating screen body 2 to prevent material from overflowing from the gap. A scraper 8 is fixedly installed at the end of the push rod 7 away from the connecting plate 6. A rotating shaft 9 is rotatably connected in the middle of the bracket 4. A gear 10 is fixedly installed on the outer side of the lower end of the rotating shaft 9.

[0019] The lower surface of the scraper 8 is in contact with the upper surface of the screen 3. The outer side of the connecting rod 5 is provided with a toothed groove, and the connecting rod 5 can mesh with the gear 10. The gear 10 is located between the left and right connecting rods 5. Rotating the shaft 9 drives the gear 10 to rotate and mesh with the connecting rod 5, thereby causing the connecting rod 5 to drive the connecting plate 6 and the push rod 7 to move back and forth in a straight line, so that the scraper 8 moves in a straight line to scrape off the material or impurities accumulated on the surface of the screen 3, thereby cleaning the screen 3.

[0020] There are multiple screens 3, multiple push rods 7 and multiple scrapers 8. Multiple screens 3 can be cleaned by multiple scrapers 8.

[0021] like Figures 1-5 As shown, the power unit includes a motor 11, which is fixedly mounted on the top of the bracket 4. A reciprocating lead screw 12 is fixedly mounted on the output end of the motor 11. A slider 13 is threadedly connected to the outside of the reciprocating lead screw 12. A rack 14 is fixedly mounted on the left side of the slider 13. A gear 2 15 is fixedly mounted on the outer side of the upper end of the rotating shaft 9.

[0022] A limiting groove is provided on the upper surface of the bracket 4. The bottom of the rack 14 is slidably connected in the limiting groove, and the rack 14 and the second gear 15 mesh with each other. When the reciprocating screw 12 and the slider 13 are threadedly connected, the rack 14 is driven to move back and forth in a linear motion through the slider 13. With the meshing of the rack 14 and the second gear 15, the rotating shaft 9 rotates clockwise and counterclockwise.

[0023] like Figure 6 As shown, the rinsing device includes a water tank 16, which is fixedly installed on the top of the support frame 1 on the left side of the vibrating screen body 2. A pump body 17 is installed on the back of the water tank 16. The output end of the pump body 17 is connected to a main pipe 18. Multiple branch pipes 19 are connected to the outside of the main pipe 18. Multiple nozzles 20 are connected to the right side of the branch pipes 19.

[0024] The right end of the nozzle 20 is located inside the vibrating screen body 2 and at the top of the screen 3. Water is sprayed out through the nozzle 20 to wash the cleaned material and impurities, thereby improving the cleaning quality of the screen 3.

[0025] Working principle: The starting motor 11 drives the reciprocating screw 12 to rotate. When the reciprocating screw 12 rotates, it is threadedly connected to the slider 13. Since the rack 14 is slidably connected to the bracket 4, the slider 13 will drive the rack 14 to move linearly. At the same time as the rack 14 moves, it meshes with the second gear 15, thereby causing the second gear 15 to drive the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it drives the first gear 10 below to rotate. The first gear 10 meshes with the toothed groove of the connecting rod 5, causing the connecting rod 5 to drive the push rod 7 to move linearly through the connecting plate 6. Since the first gear 10 is distributed between the left and right connecting rods 5, the front and rear scrapers 8 move towards or away from each other, cleaning and scraping away the material and impurities accumulated on the surface of the screen 3.

[0026] Then, the pump body 17 is started to introduce clean water from the water tank 16 into the main pipe 18. As the clean water flows along the main pipe 18, it enters the branch pipes 19 and is sprayed out by the nozzles 20 to wash the screen 3, washing away the impurities and materials. The cleaned water is then discharged from the discharge port at the right end of the vibrating screen body 2, thus cleaning the screen 3.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
