A brick-making drum screening device with a dustproof structure

Abstract

This utility model discloses a drum screen for brick making with a dustproof structure, including a processing box. The upper end of the processing box is connected to a feed cylinder, and the lower end is connected to a discharge pipe. A dustproof structure is installed inside the feed cylinder. The dustproof structure includes a sliding groove, a fixed block, a movable plate, a sliding block, a lower connecting block, a return spring, and an upper connecting block. When bricks are fed through the feed cylinder, the inverted V-shaped fixed block guides the bricks. When the bricks fall onto the movable plate, due to gravity, the movable plate can not only slide within the sliding groove of the feed cylinder via the sliding block, but also tilt and discharge the bricks through the cooperation of the upper connecting block, the lower connecting block, and the return spring. After the bricks are discharged, the movable plate returns to its original position. This dustproof structure not only allows for natural feeding through the feed cylinder but also reduces the amount of dust that diffuses into the air during processing, thus enhancing the practicality of the drum screen for brick making.

Description

Technical Field

[0001] This utility model relates to the field of screening equipment, specifically a drum screening device for brick making with a dustproof structure. Background Technology

[0002] A drum screen is a screening device that uses rotating drums for screening. It is mainly used for screening granular and powdery materials, especially in applications requiring high-precision screening, such as in the building materials industry, brick making, sand making, mining, and chemical industries. Drum screens are a commonly used screening equipment.

[0003] A drum screen for brick making is a widely used screening equipment in brick and tile production. It is mainly used to screen raw materials to ensure the consistency of brick size and quality. Its working principle is to separate the raw materials under the action of the screen through the rotating drum, thereby obtaining brick raw materials of different specifications.

[0004] Most of the drum screens used in brick making on the market are installed inside the processing box for brick making. Since the upper part of the processing box is equipped with a feed cylinder for feeding brick raw materials, if the feed cylinder is always open, the dust generated by the screening of bricks when the drum screen rotates will spread into the air through the feed cylinder and cause environmental pollution. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that the dust generated by existing brick-making drum screens will cause environmental pollution, and to provide a brick-making drum screen with a dustproof structure.

[0006] To achieve its purpose, this utility model adopts the following technical solution:

[0007] A brick-making drum screening device with a dustproof structure includes a processing box, in which a drum screen is installed; the top of the processing box is provided with a feed cylinder, and the bottom is provided with a discharge pipe, and the feed cylinder is provided with a dustproof structure.

[0008] The dustproof structure includes a set of sliding grooves disposed on the inner sidewall of the feed cylinder, a set of movable plates extending to the middle of the feed cylinder and having a pre-reserved notch are slidably disposed in the sliding grooves, an upper connecting block is hinged to the bottom of the movable plate, a lower connecting block is disposed on the inner sidewall of the feed cylinder below the sliding grooves, and a return spring is disposed between the upper connecting block and the lower connecting block; an inverted V-shaped fixing block is disposed on the inner sidewall of the feed cylinder perpendicular to the direction of the movable plate, and the two ends of the fixing block overlap with the movable plate respectively.

[0009] As a further improvement to the technical solution of this utility model, the movable plate is slidably disposed in the sliding groove by means of a sliding block provided at its end.

[0010] Furthermore, a drive motor is provided at the center of the top of the processing box, and the output end of the drive motor passes through the processing box and is connected to the rotating shaft. The lower end of the rotating shaft is fixedly connected to the drum screen.

[0011] Furthermore, an electric telescopic rod is hinged to the inner wall of the longitudinal section of the drum screen, and the output end of the electric telescopic rod faces the transverse section of the drum screen and is hinged to a discharge plate. The discharge plate is hinged to the inner wall of the transverse section of the drum screen.

[0012] Furthermore, at least one set of discharge structures is provided below the drum screen in the processing box. The discharge structure includes a discharge plate, a discharge pipe and a screen. The discharge plate is inclined downward on the inner wall of the processing box, the discharge plate is provided with a screen, and the discharge pipe is provided at the lower end of the discharge plate.

[0013] Furthermore, a control valve one is provided on the discharge pipe, and a control valve two is provided on the discharge pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention features a dustproof structure within the feed cylinder of the processing box, comprising a sliding groove, a fixed block, a movable plate, a lower connecting block, a return spring, and an upper connecting block. When bricks are fed through the feed cylinder, the inverted V-shaped fixed block guides the material. When the bricks fall onto the movable plate, gravity causes the plate to slide within the sliding groove of the feed cylinder via the sliding block, and the upper connecting block, lower connecting block, and return spring work together to tilt the bricks downwards. After the bricks are discharged, the movable plate returns to its original position. This dustproof structure allows for natural feeding through the feed cylinder and reduces dust dispersion into the air during processing, thus enhancing the practicality of the brick-making drum screen.

[0021] The structure and working process of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figure 1-4 The present invention provides a brick-making drum screening device with a dustproof structure, including a processing box 1, a drum screen 5 inside the processing box 1; a feeding cylinder 2 is provided at the top of the processing box 1 and a discharge pipe 9 is provided at the bottom, and a dustproof structure is provided inside the feeding cylinder 2;

[0023] The dustproof structure includes a set of sliding grooves 13 disposed on the inner wall of the feed cylinder 2. A set of movable plates 11 extending to the middle of the feed cylinder 2 and having a pre-reserved notch are slidably disposed in the sliding grooves 13. An upper connecting block 16 is hinged to the bottom of the movable plate 11. A lower connecting block 14 is disposed on the inner wall of the feed cylinder 2 below the sliding grooves 13. A return spring 15 is disposed between the upper connecting block 16 and the lower connecting block 14. An inverted V-shaped fixing block 10 is disposed on the inner wall of the feed cylinder 2 perpendicular to the direction of the movable plate 11. The two ends of the fixing block 10 overlap with the movable plate 11 respectively.

[0024] Specifically, the movable plate 11 is slidably disposed in the sliding groove 13 by means of the sliding block 12 provided at its end.

[0025] Specifically, a drive motor 3 is provided at the center of the top of the processing box 1. The output end of the drive motor 3 passes through the processing box 1 and is connected to the rotating shaft 4. The lower end of the rotating shaft 4 is fixedly connected to the drum screen 5.

[0026] Specifically, an electric telescopic rod 7 is hinged to the inner wall of the longitudinal section of the drum screen 5. The output end of the electric telescopic rod 7 faces the horizontal section of the drum screen 5 and is hinged to a discharge plate 6. The discharge plate 6 is hinged to the inner wall of the horizontal section of the drum screen 5.

[0027] Specifically, two sets of discharge structures 8 are provided below the drum screen 5 on the processing box 1. Each discharge structure 8 includes a discharge plate 801, a discharge pipe 802, and a screen 803. The discharge plate 801 is inclined downwards on the inner wall of the processing box 1, and the screen 803 is provided on the discharge plate 801.
