Novel screen cloth heating tension compensation vibrating screen

Abstract

In the industries of chemical engineering, metallurgy, building materials and the like, a vibrating screen usually adopts the design of a tensioning type metal woven screen with two stretched ends, when high-temperature materials are screened, due to thermal expansion caused by temperature conduction on the whole screen, the screen is lengthened and loses original tension, screen steel wires are broken due to fatigue for a long time, and the screen is damaged. Therefore, the screening efficiency and the stability of the screen are influenced. The utility model designs a novel screen cloth heating tension compensation vibrating screen, which mainly comprises a vibrating table, a screen cloth, a guide sliding block, a guide rail A, a guide rail B and a spring, and is characterized in that the guide rail A is arranged on the vibrating table; the guide rail B is mounted on the vibration table; the screen is connected with the vibration table through the guide sliding block. When the vibrating screen works at high temperature and the screen cloth is lengthened, the pre-tightened springs are used for compensation, and the guide sliding blocks move towards the lengthening direction of the screen cloth under the action of the springs in different directions, so that the screen cloth is tightened again, and the vibrating screen can still work normally.

Description

Technical Field

[0001] The utility model belongs to the field of vibrating screens, in particular to a vibrating screen with heated tension compensation. Background Art

[0002] Vibrating screens are an important equipment widely used in the screening of solid particulate materials. Their main function is to separate and classify particles in a mixture according to certain specifications. In the chemical, metallurgical, and building materials industries, the screening of many materials needs to be carried out in a high-temperature environment. Vibrating screens often use a tensioned metal woven screen design with both ends stretched. When screening high-temperature materials, the thermal expansion caused by the temperature conduction across the entire screen can cause the screen to become longer and lose its original tension. This will cause the screen to become loose and vibrate, colliding with the beam that originally supported the screen. Over time, the screen wire will break due to fatigue, which will affect the screening efficiency and stability of the screen. Utility Model Content

[0003] In response to the deficiencies in the existing technology, the utility model designs a new type of screen heating tension compensation vibrating screen. By presetting the spring tension in the stretching section of the screen, when the screen becomes longer, the pre-tightened spring compensates, ensuring that the vibrating screen can still work normally.

[0004] A new type of screen heated tension compensation vibrating screen mainly includes a vibrating table, a screen, a guide block, a guide rail A, a guide rail B and a spring; the guide rail A is installed on the vibrating table; the guide rail B is installed on the vibrating table; the screen is connected to the vibrating table through the guide block.

[0005] Furthermore, the guide slider consists of a slider and a guide rod.

[0006] Furthermore, the rear end and both sides of the screen are provided with holes, and the guide rods pass through the holes of the screen to guide the deformation direction of the screen.

[0007] Furthermore, a spring is installed between the screen and the slider, and the spring tension is preset; the two ends of the spring are respectively fixed on the slider and the screen; the slider can move back and forth in the guide rail B; the front end of the screen can move back and forth in the guide rail A.

[0010] In the figure: 1-vibrating table; 2-screen; 3-guide block, 3a-slider, 3b-guide rod; 4-guide rail A; 5-guide rail B; 6-spring. DETAILED DESCRIPTION

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0012] like Figure 1 、 2 The figure shows a large-scale feed vibrating screen based on a dual vibrator. It primarily comprises a vibrating table 1, a screen 2, a guide block 3, guide rails A4 and B5, and a spring 6. Guide rails A4 and B5 are mounted on the vibrating table 1. The screen 2 is connected to the vibrating table 1 via the guide block 3. The guide block 3 consists of a slider 3a and a guide rod 3b. The screen 2 has holes at its rear end and on both sides, and the guide rods 3b pass through the holes in the screen 2. A spring 6 is installed between the screen 2 and the slider 3a, with a preset spring tension. The ends of the spring 6 are fixed to the slider 3a and the screen 2, respectively. The slider 3a can reciprocate within the guide rail B5, and the front end of the screen 2 can reciprocate within the guide rail A4. When the vibrating screen operates at high temperatures and the screen lengthens, a preloaded spring compensates. The guide block, acting in opposite directions from the spring, moves in the direction of the lengthening screen, re-tensioning the screen, ensuring the vibrating screen continues to function properly. This allows the screen to automatically tighten during operation.

[0013] The above description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any variation, modification, substitution, integration, or parameter change to these embodiments, which falls within the spirit and principles of the present invention and achieves the same functionality through conventional substitutions, without departing from the principles and spirit of the present invention, falls within the scope of protection of the present invention.
