Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a vibrating screen for processing nepheline ore. Background Technology

[0002] Nepheline ore, a high-hardness silicate mineral, is in high demand in the glass and ceramics industries. Its processing requires multi-stage screening to obtain products with different particle sizes. Vibrating screens are the core sorting equipment in nepheline ore production lines. However, due to the high hardness and sharp edges of nepheline ore, the wear rate of the screen plates is much higher than that of ordinary ores. The screen plates need to be replaced every few days, which places extremely high demands on the equipment maintenance efficiency.

[0003] Currently, vibrating screens in nepheline mines generally adopt a bolt-fastened screen plate fixing structure. The four corners of the screen plate are directly locked to the internal frame of the machine casing by bolts. When replacing, the operator needs to use a wrench to remove all the bolts one by one. The dust removal system is mostly connected to the bag filter on the side of the machine casing by flanges.

[0004] However, this bolt fixing method has significant problems in actual maintenance of the screen plate. Since the internal space of the machine casing is usually relatively narrow, each time the worn screen plate is replaced, the operator needs to use special tools to disassemble and retighten a large number of bolts one by one. The process is cumbersome and laborious, not only taking a long time, but also often requiring the cooperation of multiple people. This directly leads to the extension of equipment downtime for maintenance and seriously affects the production efficiency of continuous processing of nepheline ore. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vibrating screen for processing nepheline ore, which aims to improve the problem of low screen plate replacement efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vibrating screen for processing nepheline ore, comprising a base, a spring fixedly connected to the upper surface of the base, a housing fixedly connected to one end of the spring, a screen plate provided inside the housing, a discharge port fixedly connected to one end of the screen plate, a connecting component provided inside the housing, and a dust removal component provided on the outer wall of the housing. The connecting assembly includes a slotted hole, a connecting block, a connecting rod, a cross hole, and a locking rod. The lower surface of the connecting block is fixedly connected to the upper surface of the sieve plate. The cross hole is opened through the outer wall of the connecting block. The slotted hole is opened through the outer wall of the machine housing. The outer wall of the connecting rod is slidably connected to the inside of the slotted hole. One end of the locking rod is fixedly connected to the outer wall of the connecting rod, and the locking rod is engaged with the inside of the cross hole.

[0007] Furthermore, the dust removal assembly includes a dust collection hood, a dust collection pipe, and a conical shell. The outer wall of the dust collection hood is fixedly connected to the outer wall of the housing, and a mesh is fixedly connected to the inner wall of the base. One end of the dust collection pipe is fixedly connected to the inner wall of the dust collection hood, and the conical shell is disposed at the other end of the dust collection pipe.

[0008] Furthermore, an air inlet is provided on the outer wall of the conical shell, a dust collection port is provided on the lower surface of the conical shell, and the other end of the dust collection pipe is provided on the inner wall of the air inlet.

[0009] Furthermore, a frame is fixedly connected to the outer wall of the conical shell, and a dust collection box is installed inside the frame, with the dust collection box located below the dust collection port.

[0010] Furthermore, an air outlet pipe is fixedly connected to the inner wall of the conical shell, one end of the air outlet pipe is located inside the conical shell, a fan is provided on the upper surface of the frame, and the output end of the fan is fixedly connected to the other end of the air outlet pipe.

[0011] Furthermore, a handle is fixedly connected to the outer wall of the connecting rod, and a second spring is sleeved on the outer wall of the connecting rod, with one end of the second spring fixedly connected to the outer wall of the machine housing.

[0012] Furthermore, a counterweight is rotatably connected to the outer wall of the housing, and a universal joint is fixedly connected to the outer wall of the counterweight.

[0013] Furthermore, a motor is provided on the upper surface of the base, and the output end of the motor is fixedly connected to one end of the universal joint.

[0014] This utility model has the following beneficial effects: In this invention, the hand lever is pushed first, and then the connecting rod is rotated to move the locking rod out of the cross hole of the screen plate connecting block. The screen plate can then be directly pulled out for replacement or maintenance. During installation, the connecting rod is pushed in the opposite direction, and the locking rod automatically engages with the cross hole to lock. The entire process requires no tools and a single person can complete the screen plate replacement, greatly reducing equipment downtime. It is especially suitable for the need for frequent screen plate replacement in the multi-stage screening process of nepheline mines.

[0015] In this invention, after the fan starts, a negative pressure is formed at the dust collection hood, which draws the screening dust into the conical shell through the dust collection pipe. The dust is slowed down by the airflow in the outlet pipe inside the conical shell and then naturally settles into the dust collection box through the dust outlet. This effectively solves the problem of dust permeation in the nepheline mine screening workshop. In addition, the dust collection box can be pulled out for cleaning, which is convenient for collecting and handling dust. Attached Figure Description

A connecting component is provided inside the housing 3 to facilitate the quick disassembly of the screen plate 4. A dust removal component is provided on the outer wall of the housing 3. The connecting component includes a slotted hole 8, a connecting block 9, and a connecting rod 11. The cross hole 10 and the locking rod 13 are connected. The lower surface of the connecting block 9 is fixedly connected to the upper surface of the screen plate 4. The connecting block 9 serves as a force-bearing fulcrum. The cross hole 10 is opened through the outer wall of the connecting block 9. The transverse channel of the cross hole 10 allows the locking rod 13 to be axially locked, and the longitudinal channel enables rotational release. The slotted hole 8 is opened through the outer wall of the housing 3. The slotted hole 8 is used to disengage and unlock the locking rod 13. The outer wall of the connecting rod 11 is slidably connected to the inside of the slotted hole 8. One end of the locking rod 13 is fixedly connected to the outer wall of the connecting rod 11. The locking rod 13 is engaged with the inside of the cross hole 10. The engagement between the locking rod 13 and the cross hole 10 is stressed to prevent the screen plate 4 from loosening during operation. The dust removal assembly includes a dust collection hood 18 and a dust collection... The pipe 19 and the conical shell 20 are fixedly connected to the outer wall of the dust collection hood 18, which is fixedly connected to the outer wall of the housing 3. A mesh 15 is fixedly connected to the inner wall of the base 1, and the dust collection hood 18 covers the mesh 15 to prevent large pieces of material from clogging the dust collection system. One end of the dust collection pipe 19 is fixedly connected to the inner wall of the dust collection hood 18, and the conical shell 20 is located at the other end of the dust collection pipe 19. An air inlet 21 is opened on the outer wall of the conical shell 20, and a dust collection port 22 is opened on the lower surface of the conical shell 20. The other end of the dust collection pipe 19 is located on the inner wall of the air inlet 21. A frame 16 is fixedly connected to the outer wall of the conical shell 20, and a dust collection box 17 is installed inside the frame 16. The dust collection box 17 can be quickly replaced and cleaned when it is full. The dust collection box 17 is located at the dust collection port. Below 22, an air outlet pipe 23 is fixedly connected to the inner wall of the conical shell 20. One end of the air outlet pipe 23 is located inside the conical shell 20 to draw clean airflow. A fan 24 is installed on the upper surface of the frame 16. The output end of the fan 24 is fixedly connected to the other end of the air outlet pipe 23. A handle 12 is fixedly connected to the outer wall of the connecting rod 11. A spring 14 is sleeved on the outer wall of the connecting rod 11. One end of the spring 14 is fixedly connected to the outer wall of the housing 3. A counterweight 7 is rotatably connected to the outer wall of the housing 3. The weight of the counterweight 7 is adjustable to adapt to different screening strength requirements. A universal joint 6 is fixedly connected to the outer wall of the counterweight 7. A motor 25 is installed on the upper surface of the base 1. The output end of the motor 25 is fixedly connected to one end of the universal joint 6.

[0020] Working principle: When using this vibrating screen for nepheline ore processing, first start the motor 25 on the base 1 to drive the universal shaft 6 to rotate, which in turn drives the counterweight 7 to generate centrifugal force. The excitation force is transmitted to the machine casing 3 through spring 2, causing the screen plate 4 to vibrate at high frequency. Nepheline ore is fed from the top of the machine casing 3 and screened by the vibrating screen plate 4. The qualified particle size and the oversized material are discharged from different outlets 5. When the screen plate 4 is worn and needs to be replaced, the operator pushes the lever 12 outward, compressing the spring 14 to make the connecting rod 11 slide along the slot 8. The locking rod 13 disengages from the cross hole 10 inside. Then, the lever 12 is rotated to drive the locking rod 13 out of the cross hole 10 of the connecting block 9. Once the screen plate 4 is dislodged from the hole 10 and the straight hole 8, it can be pulled out from the machine housing 3. When installing a new screen plate 4, align the connecting block 9 with the positioning groove inside the machine housing 3, push it in the opposite direction and rotate the lever 12. The spring 14 resets and pushes the locking rod 13 to automatically engage with the cross hole 10 to complete the locking. During the screening process, after the fan 24 starts, a negative pressure is formed at the dust collection hood 18. The dust is drawn in through the dust collection pipe 19 from the air inlet 21 of the conical shell 20. The dust is slowed down by the airflow disturbance of the air outlet 23 inside the conical shell 20 and falls into the dust collection box 17 from the dust outlet 22 by gravity settling. The screen 15 blocks large particles from entering the dust collection system. The dust collection box 17 can be pulled out along the frame 16 for cleaning.
