A vibrating screen with adjustable screen aperture

Abstract

This utility model relates to an adjustable screen aperture vibrating screen. In actual production, when the screen aperture size needs to be adjusted, a moving component can be operated to move the top screen plate appropriately on the upper surface of the bottom screen plate. This adjusts the overlapping portion between the first and second waist-shaped holes. By adjusting the appropriate overlapping portion, the required aperture diameter for the graphite raw material can be adjusted, facilitating the screening of materials of suitable size. To prevent excessive material from clogging the steps formed by the second waist-shaped hole on the top screen plate and the bottom screen plate, the thickness of the top screen plate is limited to restrict the step height. When the vibrating body drives the bottom and top screen plates to vibrate and screen, the lower step makes it easier for the raw material to be vibrated out for further screening. This allows for better adjustment of the screen aperture diameter according to screening needs, reduces operator disassembly, and thus improves screening efficiency.

Description

Technical Field

[0001] This utility model relates to the field of screening equipment for graphite production raw materials, and in particular to a vibrating screen with adjustable screen aperture. Background Technology

[0002] A screening machine is a vibrating screening machine that uses the relative motion between granular materials and the screen surface to allow some particles to pass through the screen holes, separating materials such as sand, gravel, and crushed stone into different grades according to particle size.

[0003] In the field of graphite production and processing technology, since different products require graphite particles of different sizes, existing screening machines cannot adjust the screening holes well according to the needs. Operators also need to disassemble the screen plates and switch to screen plates with appropriate hole diameters for screening, which reduces screening efficiency and is time-consuming and labor-intensive.

Detailed Implementation

[0025] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Please refer to Figures 1 to 5 As shown, the present invention provides a vibrating screen with adjustable screen aperture, comprising a vibrating body and a screen aperture 105 adjustable screening mechanism 1, wherein the screen aperture 105 adjustable screening mechanism 1 is inclinedly arranged inside the vibrating body.

[0027] The adjustable sieving mechanism 1 with sieve holes 105 includes a mounting side plate 101, a bottom sieve plate 102, a top sieve plate 103, and several sets of moving components. Both sides of the bottom sieve plate 102 are detachably connected to the vibrating body through the mounting side plate 101. Several first waist-shaped holes are arranged on the bottom sieve plate 102, and several second waist-shaped holes 106 are arranged on the top sieve plate 103. One first waist-shaped hole corresponds to one second waist-shaped hole 106. The top sieve plate 103 is slidably connected to the upper surface of the bottom sieve plate 102. Several sets of moving components are synchronously driven and connected to the top sieve plate 103.

[0028] The thickness of the top screen plate 103 is less than 1 cm.

[0029] The working principle of this utility model is as follows: In actual production and use, when it is necessary to adjust the size of the sieve hole 105, the moving component can be operated to move the top sieve plate 103 appropriately on the upper surface of the bottom sieve plate 102, thereby adjusting the overlapping part between the first waist-shaped hole and the second waist-shaped hole 106. By adjusting the appropriate overlapping part, the required aperture of the graphite raw material can be adjusted, making it easier to screen out raw materials of suitable size. In order to prevent the step 104 formed by the second waist-shaped hole 106 on the top sieve plate 103 and the bottom sieve plate 102 from entering the hole with too much raw material, the height of the step 104 is limited by limiting the thickness of the top sieve plate 103. When the vibrating body drives the bottom sieve plate 102 and the top sieve plate 103 to vibrate and screen, the lower step 104 makes it easier for the raw material to be shaken out for further screening.

[0030] Furthermore, the moving component includes a linear drive 109 and a moving slider 108. The upper part of the bottom screen plate 102 is provided with a moving groove 111 adapted to the moving slider 108. The bottom surface of the top screen plate 103 is slidably connected to the groove through the moving slider 108. The linear drive 109 is linearly driven connected to the moving slider 108.

[0031] As can be seen from the above description, when it is necessary to adjust the size of the sieve hole 105 formed by the alternation of the first waist-shaped hole and the second waist-shaped hole 106, several linear drive units 109 can be operated simultaneously, so that the linear drive units 109 drive the top sieve plate 103 to move to a suitable distance through the moving slider 108, thereby adjusting the overlapping part between the first waist-shaped hole and the second waist-shaped hole 106 to obtain the required size of the sieve hole 105.

[0032] Furthermore, the adjustable screening mechanism 1 with screen holes 105 also includes a limiting slider 107. The bottom screen plate 102 is provided with a plurality of limiting grooves 110 that are adapted to the limiting slider 107. The lower part of the limiting slider 107 is slidably connected to a limiting groove 110, and the upper part of the limiting slider 107 is connected to the top screen plate 103.

[0033] As can be seen from the above description, it is beneficial to limit the movement between the top screen plate 103 and the bottom screen plate 102 by using several limiting sliders 107, so as to prevent the top screen plate 103 from bulging and affecting the screening.

[0034] Furthermore, the vibration body includes a vibration motor 4, a base 3, an elastic element 5, and a machine tool 2. The machine tool 2 is connected to the base 3 on all four sides through an elastic element 5. The vibration motor 4 is detachably connected to the outer surface of the machine tool 2. The inner side of the machine tool 2 is provided with a mounting groove that is compatible with the mounting side plate 101. The mounting side plate 101 is detachably connected to the mounting groove.

[0035] As can be seen from the above description, when it is necessary to screen graphite raw materials, the vibration motor 4 can be operated, so that the vibration motor 4 drives the top screen plate 103 and the bottom screen plate 102 to vibrate through the machine tool 2, so that the raw materials slide down from high to low and are screened. The raw materials smaller than the screen holes 105 formed by the first waist-shaped hole and the second waist-shaped hole 106 pass through the screen holes 105 and enter the bottom screen plate 102 for discharge, while the raw materials larger than the screen holes 105 formed by the first waist-shaped hole and the second waist-shaped hole 106 continue to slide down along the top screen plate 103 and be discharged.

[0036] Furthermore, it also includes a feed hopper 6, which is provided above the higher end of the top screen plate 103, and the feed hopper 6 is fixedly connected to the machine tool 2.

[0037] As can be seen from the above description, it is beneficial to introduce the raw materials into the screening machine for screening in a better way through the feed hopper 6.

[0038] Furthermore, it also includes a PLC controller, which is electrically connected to both the vibrating body and the adjustable screening mechanism 1 with screen holes 105.

[0039] As can be seen from the above description, it is beneficial to adjust the parameters of the adjustable vibrating screen with 105 screen openings through the PLC controller, and it makes it more convenient for operators to operate the adjustable vibrating screen with 105 screen openings.
