Description

Technical Field

[0001] The utility model relates to the technical field of ceramic raw material screening, in particular to a screening device for ceramic raw material processing. Background Technique

[0002] Screening is a process of separating a mixture of waste with different particle sizes into two or more groups of particles by using one or more sieve surfaces. There are usually two operations, wet screening and dry screening. Dry screening is often used for screening solid waste, and multiple sieve surfaces can be used simultaneously during screening. The screening process can be divided into two processes: material stratification and fine particle penetration through the sieve. Among them, fine particle penetration through the sieve is the purpose of separation.

[0003] In the prior art, a patent with the publication number of CN112387572A discloses a screening device for ceramic raw material processing, including a screening box. An L-shaped support plate is fixedly connected to the screening box. A servo cylinder is fixedly connected to the first mounting plate by screws. A first connecting rod is fixedly connected to the output shaft of the servo cylinder through a coupling. A first leakage plate is fixedly installed on the first connecting rod. A collection box is arranged at the air outlet of the fan. A servo motor is fixedly installed on the third mounting plate by screws. A second connecting rod is in transmission connection with the output shaft of the servo motor through a coupling. A turning plate is fixedly installed on the second connecting rod by fixing screws. A second leakage plate is fixedly installed in the screening box. This device stirs ceramic raw materials through the turning plate, screens large ceramic raw materials through the first leakage plate, and screens small ceramic raw materials through the second leakage plate. When used in cooperation with a fan, it has the advantage of improving screening efficiency. However, the following problems are still found during use. The first leakage plate cannot take out all the large ceramic raw materials scattered on the second leakage plate. Because the second leakage plate is horizontally arranged, the ceramic raw materials scattered near the end of the second leakage plate will not be contacted by the first leakage plate, resulting in a use defect. Moreover, this device can only perform primary screening and cannot perform multi-level screening of ceramic raw materials with different sizes. Therefore, those skilled in the art have proposed a screening device for ceramic raw material processing to solve the problems raised in the above background. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions of the present utility model will be further described in detail below in conjunction with the specific embodiments.

[0021] Embodiment 1: Please refer to Figures 1 to 4, A screening device for ceramic raw material processing, including a base 1, a box body 2 is arranged on the base 1, a feeding frame 3 is arranged at the top end of the box body 2, a discharge port 4 is arranged at the bottom end of the box body 2, and a number of sieve frames 5 are arranged at equal intervals along the vertical direction in the inner cavity of the box body 2. The sieve frame 5 is in the shape of a cylindrical barrel, an elastic cloth 8 is arranged at the bottom of the sieve frame 5, and a number of fan-shaped mounting frames 9 are evenly distributed in a circular pattern on the elastic cloth 8. The edge of the elastic cloth 8 is connected to the inner wall of the sieve frame 5. By cutting a notch corresponding to the shape and size of the mounting frame 9 on the elastic cloth 8, and then installing the mounting frame into the notch, the outer wall of the mounting frame 9 is connected to the inner wall of the notch. The elastic cloth 8 can be connected to the sieve frame 5 and the mounting frame 9 by bonding or fixing nails. A sieve mesh plate 10 is detachably installed on the mounting frame 9. The sieve mesh plate 10 is installed on the mounting frame 9 by bolts. After the sieve mesh plate 10 is installed, the top ends of the elastic cloth 8, the mounting frame 9, and the sieve mesh plate 10 are flush. The center of the elastic cloth 8 is connected with a vertical cylinder 11. A first telescopic member 7 is arranged directly below the vertical cylinder 11 through a first mounting frame 6. The first mounting frame 6 is installed on the inner wall of the box body 2. The top end of the first telescopic member 7 is connected to the bottom end of the vertical cylinder 11. A side discharge pipe 14 is connected to the side of the vertical cylinder 11. The lower part of the side discharge pipe 14 is inserted and fitted with the upper part of a discharge pipe 15. When the first telescopic member 7 drives the vertical cylinder 11 to move, the lower part of the side discharge pipe 14 and the upper part of the discharge pipe 15 always remain connected. The lower part of the discharge pipe 15 is inclined, and the bottom end of the discharge pipe 15 extends to the outside of the box body 2. The sieve frame 5 sizes of several sieve mesh plates 10 gradually decrease from top to bottom, and the top end of the vertical cylinder 11 can be opened and closed.

[0022] Please refer to Figure 1 , Figure 3 , the first telescopic member 7 is arranged on the central axis in the height direction of the sieve frame 5. The upper part of the side discharge pipe 14 is inclined, the lower part of the side discharge pipe 14 and the upper part of the discharge pipe 15 are both arranged along the vertical direction. A second telescopic member 12 is installed on the inner bottom surface of the vertical cylinder 11. The top end of the second telescopic member 12 is connected with a sealing plate 13. The outer wall of the sealing plate 13 fits with the inner wall of the vertical cylinder 11. The first telescopic member 7 and the second telescopic member 12 are both selected as electric telescopic rods and are connected to an external control circuit. The top end of the sealing plate 13 is provided with an inclined surface, and the inclined surface is inclined downward towards the side discharge pipe 14. When the sealing plate 13 moves downward, the ceramic raw materials falling on the top end of the sealing plate 13 slide down to the side discharge pipe 14 through the inclined surface.

[0023] Embodiment 2: Refer to Figure 1 , Figure 3, on the basis of the first embodiment, a vertebral plate 17 is arranged in the upper part of the inner cavity of the sieve frame 5 through a second mounting frame 16. The vertebral plate 17 is arranged directly above the vertical cylinder 11. The ceramic raw materials falling from the feeding frame 3 or from the bottom of the previous sieve frame 5 are diffused through the vertebral plate 17, so that the ceramic raw materials fall evenly onto each sieve mesh plate 10, avoiding accumulation.

[0024] Please refer to Figure 1 , Figure 3 , a circular ring plate 18 is connected to the bottom end of the sieve frame 5. The circular ring plate 18 is inclined downward from the periphery to the inner periphery. Through the circular ring plate 18, the ceramic raw materials screened out by the previous sieve frame 5 can fall better into the next sieve frame 5.

[0025] Working principle: When in use, ceramic raw materials are added through the feeding frame 3. The ceramic raw materials fall onto the sieve mesh plate 10 in the uppermost sieve frame 5, and the sealing plate 13 seals the top end of the vertical cylinder 11. First, the first telescopic member 7 drives the vertical cylinder 11 to move upward. At this time, the elastic cloth 8 bulges upward (as shown in Figure 5 ), and the ceramic raw materials roll from the center of the elastic cloth 8 to the edge. Then, the first telescopic member 7 drives the vertical cylinder 11 to move downward. At this time, the elastic cloth 8 sags downward (as shown in Figure 6 ), and the ceramic raw materials roll from the edge of the elastic cloth 8 to the center. This process is repeated, so that the ceramic raw materials roll back and forth and pass through the sieve mesh plate 10. The sieve mesh plate 10 screens the ceramic raw materials. The qualified-sized ceramic raw materials pass through the sieve mesh plate 10 and fall into the next sieve frame 5 for the next-level screening until they are discharged from the discharge port 4 and the qualified-sized ceramic raw materials are collected. The unqualified-sized ceramic raw materials remain on the sieve mesh plate 10, causing the elastic cloth 8 to sag downward. Then, the second telescopic member 12 drives the sealing plate 13 to move downward to below the connection between the side discharge pipe 14 and the vertical rod. At this time, the top end of the vertical cylinder 11 is opened, and the unqualified-sized ceramic raw materials slide into the vertical cylinder 11 and then slide down to the side discharge pipe 14 through the inclined surface at the top of the sealing plate 13, and finally are discharged and collected by the discharge pipe 15. Different discharge pipes 15 collect unqualified ceramic raw materials of different sizes.
