Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a vibrating screen that is easy to clean. Background Technology

[0002] A vibrating screen is a filtering mechanical separation device with advantages such as high efficiency, light weight, and a complete range of samples. In the process of screening zinc calcined sand, zinc calcined sand is poured into the vibrating screen funnel for screening.

[0003] When screening zinc calcined sand, the zinc calcined sand is poured into the top of the vibrating screen hopper, and then screened through the screen set at the top of the vibrating screen hopper. When the vibrating screen hopper is working, a large number of large pieces of zinc calcined sand will remain on the top of the screen, which is inconvenient for continuous screening. Therefore, the large pieces of zinc calcined sand on the top of the screen can only be manually cleaned, which is a cumbersome operation. At the same time, during the screening process, the screen is easily blocked by zinc calcined sand particles, which reduces the screening efficiency and makes it inconvenient to screen zinc calcined sand for a long time.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, an easy-to-clean vibrating screen includes a vibrating screen hopper 1. A screen 2 is fixedly installed on the inner top wall of the vibrating screen hopper 1. A discharge port 3 for discharging large pieces of zinc calcined abrasive is opened on one side of the vibrating screen hopper 1. A movable plate 4 is slidably installed inside the top of the vibrating screen hopper 1 corresponding to the position above the screen 2. A lifting plate 5 is slidably installed below the movable plate 4. Triangular blocks 6 are fixedly installed at equal intervals at the bottom of the lifting plate 5. A sealing plate 7 is slidably installed up and down on one side of the top of the vibrating screen hopper 1 corresponding to the position of the discharge port 3. The sealing plate 7 can block the discharge port 3. The zinc calcined abrasive material is poured into the top of the vibrating screen hopper 1. By controlling the vibration of the vibrating screen hopper 1 and the screening of the zinc calcined abrasive material by the screen 2, the zinc calcined abrasive material is effectively discharged. The calcined zinc ore is screened. Small pieces of calcined zinc ore fall from the middle of screen 2 to the bottom of vibrating screen hopper 1 and are discharged. Large pieces of calcined zinc ore remain above screen 2. During long-term screening, the moving plate 4 and the lifting plate 5 are controlled to move and push the large pieces of calcined zinc ore above screen 2 to the discharge port 3. The large pieces of calcined zinc ore are then discharged from the discharge port 3, facilitating the cleaning and discharge of the large pieces of calcined zinc ore on screen 2. During the movement of the moving plate 4 and the lifting plate 5, the triangular block 6 at the bottom of the lifting plate 5 squeezes the particles in the screen holes of screen 2, squeezing the particles out of screen 2 for cleaning screen 2 and improving the screening effect of calcined zinc ore.

[0022] like Figures 1 to 4 As shown, limit rods 9 are symmetrically fixedly installed on the inner wall of the top of the vibrating screen hopper 1, and the moving plate 4 is slidably installed between the two limit rods 9.

[0023] The movable plate 4 can slide between the two limit rods 9 for positioning and moving.

[0024] like Figures 1 to 4 As shown, a rotating rod 10 is symmetrically mounted on the top of the vibrating screen hopper 1 via a bearing. Two rope-supporting wheels 11 are symmetrically fixed at both ends of the rotating rod 10. A steel wire rope 12 is driven between the two rope-supporting wheels 11 on the same side. The middle part of the steel wire rope 12 is fixedly connected to the moving plate 4. A motor 13 is fixedly mounted on one side of the vibrating screen hopper 1 at one end of one of the rotating rods 10. The output end of the motor 13 is fixedly connected to one end of the rotating rod 10.

[0025] The operation of motor 13 drives the rotating rod 10 to rotate. The transmission of the rope rollers 11 on the two rotating rods 10 through the wire rope 12 will drive the two rotating rods 10 to rotate synchronously. At the same time, the wire rope 12 will also move, which will drive the moving plate 4 installed on the wire rope 12 to slide between the limit rods 9. The moving plate 4 and the lifting plate 5 will push the large piece of zinc calcined sand material above the screen 2.

[0026] like Figures 1 to 4 As shown, slide rods 14 are symmetrically slidably installed on one side of the vibrating screen hopper 1. The bottom of the two slide rods 14 is fixedly connected to the sealing plate 7. A first return spring 15 is sleeved on the outer side of the bottom end of the slide rod 14. One end of the first return spring 15 is fixedly connected to the sealing plate 7, and the other end of the first return spring 15 is fixedly connected to the vibrating screen hopper 1.

[0027] Control the sealing plate 7 to rise, cancel the sealing plate 7 from blocking the outlet 3. As the moving plate 4 and the lifting plate 5 continue to move, they will push the large pieces of zinc roasted sand material out of the outlet 3.

[0028] like Figures 1 to 4 As shown, a trapezoidal block 16 is fixedly installed in the middle of the movable plate 4, and an installation block 17 is fixedly installed on the top of the two slide rods 14. An extrusion groove 18 is opened in the middle of the installation block 17 corresponding to the position of the trapezoidal block 16, and the extrusion groove 18 is in extrusion contact with the end slope of the trapezoidal block 16.

[0029] When the moving plate 4 moves to the vicinity of the discharge port 3, the end slope of the trapezoidal block 16 on the moving plate 4 will press the extrusion groove 18 in the middle of the mounting block 17, which will drive the sealing plate 7 indirectly connected to the mounting block 17 to rise, thereby canceling the sealing plate 7 from blocking the discharge port 3.

[0030] like Figures 1 to 4As shown, a positioning rod 19 is fixedly installed on the top of the lifting plate 5. The positioning rod 19 is slidably installed inside the moving plate 4. A second return spring 20 is sleeved on the outer side of the top of the positioning rod 19. One end of the second return spring 20 is fixedly connected to the top of the positioning rod 19, and the other end of the second return spring 20 is fixedly connected to the top of the moving plate 4.

[0031] During the movement of the moving plate 4 and the lifting plate 5, the second reset spring 20 pulls the positioning rod 19, causing the triangular block 6 at the bottom of the lifting plate 5 to insert into the screen hole in the screen 2. As the moving plate 4 and the lifting plate 5 move, the triangular block 6 will squeeze the screen hole in the screen 2, causing the lifting plate 5 to rise and slide out of the screen hole in the screen 2, which is used to control the reciprocating lifting of the lifting plate 5.

[0032] like Figures 1 to 4 As shown, a feeding plate 8 is fixedly installed on the vibrating screen hopper 1 at the position corresponding to the discharge port 3.

[0033] When the large pieces of zinc calcined abrasive are pushed to the discharge port 3 and discharged from the discharge port 3, the large pieces of zinc calcined abrasive are discharged through the discharge plate 8.

[0034] This utility model provides a vibrating screen that is easy to clean, and its specific working principle is as follows:

[0035] When the device is in use, zinc calcined ore is poured into the top of the vibrating screen hopper 1. By controlling the vibration of the vibrating screen hopper 1 and the screening of the zinc calcined ore by the screen 2, the zinc calcined ore is screened. Small pieces of zinc calcined ore will fall from the middle of the screen 2 to the bottom of the vibrating screen hopper 1 and be discharged. Large pieces of zinc calcined ore will remain above the screen 2. During long-term screening, the operation of the motor 13 drives the rotating rod 10 to rotate. The transmission of the rope pulleys 11 on the two rotating rods 10 through the wire rope 12 will drive the two rotating rods 10 to rotate synchronously. At the same time, the wire rope 12 will also move, which will drive the moving plate 4 installed on the wire rope 12 to slide between the limit rods 9. The moving plate 4 and the lifting plate 5 will push the large pieces of zinc calcined ore above the screen 2, pushing the large pieces of zinc calcined ore to the outlet. When the moving plate 4 moves to the vicinity of the discharge port 3, the end slope of the trapezoidal block 16 on the moving plate 4 will press the extrusion groove 18 in the middle of the mounting block 17, which will drive the sealing plate 7 indirectly connected to the mounting block 17 to rise, thus canceling the sealing plate 7 from blocking the discharge port 3. At this time, the first return spring 15 is in a compressed state. As the moving plate 4 and the lifting plate 5 continue to move, they will push the large piece of zinc roasted sand material out of the discharge port 3. Then, the operation of the motor 13 will drive the rotating rod 10 to rotate in the opposite direction. Similarly, the moving plate 4 can be driven to slide in the opposite direction along the limit rod 9 and move to the initial position. At this time, the end slope of the trapezoidal block 16 will cancel the extrusion groove 18 in the middle of the mounting block 17. Under the push of the first return spring 15 on the sealing plate 7, the sealing plate 7 will block the discharge port 3.

[0036] During the movement of the moving plate 4 and the lifting plate 5, the second return spring 20 pulls the positioning rod 19, causing the triangular block 6 at the bottom of the lifting plate 5 to insert into the screen hole in the screen 2. As the moving plate 4 and the lifting plate 5 move, the triangular block 6 will squeeze the screen hole in the screen 2, causing the lifting plate 5 to rise and slide out of the screen hole in the screen 2. This is used to control the reciprocating lifting of the lifting plate 5, which can squeeze the particles in the screen hole of the screen 2 and squeeze them out of the screen 2 for cleaning the screen 2 and improving the screening effect of zinc roasted sand.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
