Description

Technical Field

[0001] This utility model relates to the field of material screening equipment technology, specifically to a novel anti-clogging device for drum screens. Background Technology

[0002] A drum screen is a cylindrical screening device that uses the rotation of the drum screen to screen materials of different sizes. It has the advantages of stable operation, low noise, convenient maintenance, easy sealing and dust collection, and long service life. Drum screens are mainly divided into inner drum and outer drum.

[0003] However, when screening sand and gravel of similar volume to the screen aperture size, the sand and gravel at the bottom of the pile will get stuck in the screen aperture of the outer cylinder due to the pressure of the sand and gravel above. Without external force, the sand and gravel cannot fall out of the screen aperture of the outer cylinder by their own weight, thus causing blockage of the screen aperture of the outer cylinder, which seriously affects the use of the equipment. In order to solve the above problem, a new type of anti-clogging device for drum screen is proposed. Utility Model Content

[0004] In view of this, the present invention provides a novel anti-clogging device for drum screens. The present invention uses a first motor to rotate the brush strips on the rotating roller, thereby cleaning the screen holes on both sides of the outer cylinder and preventing screen hole clogging. A second motor drives the rotating shaft to rotate the positioning sleeve, thereby rotating the polyurethane belt installed on the positioning sleeve and tapping the screen holes on the outer cylinder to prevent screen hole clogging, thus stabilizing the operating conditions of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel anti-clogging device for a drum screen, comprising a drum screen body arranged along the front-to-back direction on a support frame, a rotating roller arranged on the left and right sides of the outer cylinder of the drum screen body, a plurality of brush strips arranged on the surface of the rotating roller, a first motor arranged at the front end of the rotating roller, a first bearing seat arranged at the rear end of the rotating roller, a rotating shaft arranged above the rotating roller, a second motor arranged at the front end of the rotating shaft, a second bearing seat arranged at the rear end of the rotating shaft, a plurality of connecting rings arranged on the surface of the rotating shaft, a positioning sleeve arranged around the connecting rings, and a polyurethane strip arranged on each positioning sleeve.

[0006] A speed regulator is provided between the rotating roller on the same side and the first motor. The speed regulator is used to adjust the rotation speed of the first motor.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0025] like Figure 1-6As shown: This embodiment provides a novel anti-clogging device for a drum screen, including a drum screen body 101 arranged along the front-to-back direction on a support frame 100. A rotating roller 200 is respectively arranged on the left and right sides of the outer cylinder of the drum screen body 101. The rotating roller 200 is used to install and fix brush strips 201, driving the brush strips 201 to rotate. Several brush strips 201 are arranged on the surface of the rotating roller 200, and the brush strips 201 are in contact with the outer cylinder wall of the drum screen. The brush strips 201 are used to clean the material stuck in the screen holes of the outer cylinder, thereby clearing the blockage. A first motor 202 is arranged at the front end of the rotating roller 200, which drives the rotating roller 200 to rotate. A first bearing seat 203 is arranged at the rear of the rotating roller 200, which is used to fix the rotating roller 200 to prevent it from falling during operation. A rotating shaft 300 is provided above the 00, and the rotating shaft 300 is used to install the connecting ring 303. A second motor 301 is provided at the front end of the rotating shaft 300, and the second motor 301 is used to drive the rotating shaft 300 to rotate. A second bearing seat 302 is provided at the rear end of the rotating shaft 300, and the second bearing seat 302 is used to fix the rotating shaft 300 to prevent it from falling. Several connecting rings 303 are provided on the surface of the rotating shaft 300. The connecting rings 303 are used to connect the positioning sleeve 304 to the rotating shaft 300, and drive the positioning sleeve 304 to rotate. A positioning sleeve 304 is provided around the connecting ring 303. The positioning sleeve 304 allows the polyurethane belt 305 to be detachably fixed to the connecting ring 303. A polyurethane belt 305 is provided on each positioning sleeve 304. The polyurethane belt 305 is used to beat the screen holes on the outer cylinder to prevent the screen holes from being blocked.

[0026] In operation, the outer cylinder of the drum screen is rotated by starting the main body 101 of the drum screen. Then, the first motor 202 is started, which drives the rotating roller 200 to rotate. This causes the brush strips 201 on the rotating roller 200 to rotate and clean the screen holes on the outer cylinder. The speed of the first motor 202 is adjusted by the regulator, which in turn adjusts the speed of the rotating roller 200 to prevent the screen holes from clogging. The second motor 301 is started, which drives the rotating shaft 300 to rotate. This causes the connecting ring 303 on the rotating shaft 300 to drive the positioning sleeve 304 to rotate. This causes the polyurethane belt 305 installed on the positioning sleeve 304 to rotate and beat the screen holes on the outer cylinder to prevent clogging. This double-layer cleaning of the screen holes on the outer cylinder of the drum screen prevents clogging and stabilizes the operating conditions of the equipment.

[0027] This embodiment provides a novel device for preventing clogging of drum screens.

[0028] like Figure 1 , 3As shown in Figure 5: A speed regulator 204 is provided between the rotating roller 200 and the first motor 202 on the same side.
