High strength alloy vibrating screen

Abstract

This utility model discloses a high-strength alloy vibrating screen, comprising two screen frames. A first sliding block is slidably connected to the top of each of the two screen frames on opposite sides. A second sliding block is slidably connected to the middle of each of the two screen frames on opposite sides. A third sliding block is slidably connected to the bottom of each of the two screen frames on opposite sides. This high-strength alloy vibrating screen, by setting a first vibration component and a second vibration component, allows the height shell to slide relative to the height rod, and the height shell compresses the return spring. The return spring undergoes elastic deformation to buffer the compressive force, improving the vibration performance of the first and second screens. The support frame slides relative to the length shell, causing the displacement block to slide along the length shell. The connecting spring undergoes elastic deformation to buffer the compressive force, increasing the vibration force between the second and third screens. When the vibration force is sufficient, the screen body vibrates strongly with low amplitude and high frequency, significantly reducing the phenomenon of material clogging the screen holes.

Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically a high-strength alloy vibrating screen. Background Technology

[0002] Vibrating screen mesh is the core component of a vibrating screen. It is usually woven, stamped, or welded from metal wire, synthetic fiber, or other high-strength materials and has a regular mesh structure. It is installed on the screen frame of the vibrating screen and achieves material grading, screening, dewatering, and other treatments through the high-frequency vibration of the screen body. Its mesh size, shape, and material are customized according to the material characteristics and process requirements. It is a key component for the vibrating screen to achieve its separation function. Vibrating screen mesh is lightweight, simple in construction, and easy to operate and maintain, thus reducing the cost of use.

[0003] However, traditional vibrating screens have the following disadvantages: Traditional vibrating screens have poor vibration force, which slows down the movement speed of materials on the screen surface, resulting in poor stratification and reduced screening rate. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength alloy vibrating screen to solve the problem mentioned in the background art that the traditional vibrating screen has poor vibration force, which leads to a slowdown in the movement speed of materials on the screen surface, resulting in poor stratification and reduced screening rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength alloy vibrating screen, comprising two screen frames, with a first sliding block slidably connected to the top of each of the two screen frames on opposite sides, a second sliding block slidably connected to the middle of each of the two screen frames on opposite sides, and a third sliding block slidably connected to the bottom of each of the two screen frames on opposite sides. A first screen is fixedly installed between the two first sliding blocks, a second screen is fixedly installed between the two second sliding blocks, and a third screen is fixedly installed between the two third sliding blocks. A plurality of first vibration components are fixedly installed between the first screen and the second screen, and between the second screen and the third screen. Several second vibration components are fixedly installed between the first and second screens. Each second vibration component includes a length shell and two support frames. The two ends of the length shell are slidably connected to the middle of the two support frames. Each first vibration component includes a height shell and a height rod. A return spring is fixedly installed at the bottom of the height shell. The bottom end of the return spring is fixedly connected to the top end of the height rod, and the height rod is slidably connected to the height shell. As the first screen moves closer to the second screen, the height shell slides relative to the height rod and compresses the return spring. The return spring is elastic, and its elastic deformation buffers the compressive force, thereby improving the vibration performance of the first and second screens.

[0006] Preferably, two symmetrically arranged positioning plates are fixedly installed inside the length shell. A connecting spring is fixedly installed on the opposite side of each of the two positioning plates. Two displacement blocks located on one side of each positioning plate are slidably connected to the length shell. The opposite sides of the two displacement blocks are fixedly connected to the opposite ends of the two support frames. As the second screen moves closer to the third screen, the support frame slides relative to the length shell, causing the displacement blocks to slide along the length shell. When the displacement blocks slide, they compress the connecting springs. The connecting springs are elastic, and their elastic deformation buffers the compressive force, increasing the vibration force between the second and third screens.

[0007] Preferably, the top ends of several upper support frames are fixedly connected to the second screen, and the bottom ends of several lower support frames are fixedly connected to the third screen. The second vibration assembly is installed between the second screen and the third screen through the support frames.

[0008] Preferably, the top ends of the plurality of height shells are fixedly connected to the first screen, the bottom ends of the plurality of height rods are fixedly connected to the second screen, the first vibration assembly is mounted on the first screen through the height shells, and the first vibration assembly is mounted on the second screen through the height rods.

[0009] Preferably, a first vibrating spring is fixedly installed at the top of the inner wall of each of the two mesh frames, and the bottom ends of the two first vibrating springs are fixedly connected to the opposite side of the two first sliding blocks. A second vibrating spring is fixedly installed at the bottom of the inner wall of each of the two mesh frames, and the top ends of the two second vibrating springs are fixedly connected to the opposite side of the two third sliding blocks. The first and second vibrating springs are elastic. When the first, second, and third screens screen the items for impurity separation, the first screen pulls the first vibrating spring from the bottom and the third screen squeezes the second vibrating spring from the top. The elastic deformation of the first and second vibrating springs buffers the pulling and squeezing forces, respectively, which facilitates the vibration screening of the screens.

[0010] Preferably, the surfaces of the first screen, the second screen, and the third screen are each provided with a plurality of filter holes. The plurality of filter holes are all fixedly configured as trapezoids. The filter holes have a trapezoidal cross-section that is narrow at the top and wide at the bottom, which can improve the leakage efficiency and avoid clogging.

[0011] Preferably, a positioning platform is fixedly installed on each of the two opposing sides of the two mesh frames, and a positioning ring is fixedly installed on both sides of the two positioning platforms. The vibrating screen is fixed to the screening machine by the positioning rings.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a first vibration component and a second vibration component, the height shell slides relative to the height rod, and the height shell squeezes the return spring. The return spring undergoes elastic deformation to buffer the squeezing force, thereby improving the vibration of the first screen and the second screen. The support frame slides relative to the length shell, causing the displacement block to slide along the length shell. The connecting spring undergoes elastic deformation to buffer the squeezing force, thereby increasing the vibration force between the second screen and the third screen. When the vibration force is sufficient, the screen body vibrates strongly with low amplitude and high frequency, which can significantly reduce the phenomenon of material clogging the screen holes. 2. By setting filter holes with a trapezoidal cross-section that is narrower at the top and wider at the bottom, the leakage efficiency can be improved while avoiding clogging, thus increasing the screening efficiency of the screen.

During the process of the first screen 3 approaching the second screen 5, the height shell 41 slides relative to the height rod 42, and the height shell 41 compresses the return spring 43. The return spring 43 is elastic, and the elastic deformation of the return spring 43 buffers the compressive force, thereby improving the vibration of the first screen 3 and the second screen 5.

The opposite side of the two displacement blocks 124 is fixedly connected to the opposite end of the two support frames 125. As the second screen 5 moves closer to the third screen 11, the support frame 125 slides relative to the length shell 121, causing the displacement blocks 124 to slide along the length shell 121. When the displacement blocks 124 slide, they compress the connecting spring 123. The connecting spring 123 is elastic, and the elastic deformation of the connecting spring 123 buffers the compressive force and increases the vibration force between the second screen 5 and the third screen 11.

A second vibrating spring 10 is fixedly installed at the bottom of the inner wall of each of the two mesh frame frames 1. The top ends of the two second vibrating springs 10 are fixedly connected to the opposite side of the two third sliding blocks 9. The first vibrating springs 13 and the second vibrating springs 10 are elastic. When the first screen 3, the second screen 5 and the third screen 11 screen the items for impurity screening, the first screen 3 pulls the first vibrating spring 13 from the bottom and the third screen 11 squeezes the second vibrating spring 10 from the top. The first vibrating springs 13 and the second vibrating spring 10 undergo elastic deformation to buffer the pulling and squeezing forces, which facilitates the vibration screening of the screens.

When the first screen 3, the second screen 5, and the third screen 11 screen the items for impurity screening, the first screen 3 pulls the first vibrating spring 13 from the bottom and the third screen 11 squeezes the second vibrating spring 10 from the top. The first vibrating spring 13 and the second vibrating spring 10 undergo elastic deformation to buffer the pulling and squeezing forces, facilitating the screen vibration screening.

The elastic return spring 43 undergoes elastic deformation to buffer the compressive force, improving the vibration of the first screen 3 and the second screen 5. As the second screen 5 approaches the third screen 11, the support frame 125 slides relative to the length shell 121, causing the displacement block 124 to slide along the length shell 121. When the displacement block 124 slides, it compresses the connecting spring 123. The connecting spring 123 is elastic, and its elastic deformation buffers the compressive force, increasing the vibration force between the second screen 5 and the third screen 11.
