Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of dolomite powder production, and particularly relates to a screen mesh anti-blocking structure for dolomite screening process. BACKGROUND

[0002] Dolomite powder is a common material, which is used in various industries, such as chemical industry, building material industry, and metallurgical industry. In the chemical industry, it can be used as a slagging agent in the steelmaking process to help remove impurities in steel and improve the quality of steel. In the building material industry, it can be used as a raw material for cement to form cement clinker with strength through reaction with other ingredients in cement. In the metallurgical industry, it can be used to produce chemical products such as magnesium oxide, magnesium hydroxide, and calcium carbonate.

[0003] The production of dolomite powder usually involves processes such as raw material crushing, transfer grinding, and screening. There is a screening device that uses a vibration motor to vibrate a screen disc with a screen mesh, allowing particles of appropriate size to fall through the mesh holes and achieve the screening effect. However, there is a situation where larger particles block the mesh holes in a certain area, making it difficult for smaller particles to fall through the mesh holes in that area, thereby affecting the screening efficiency. SUMMARY

[0004] To address the technical problems in the prior art, the utility model provides a screen mesh anti-blocking structure for dolomite screening process to alleviate the problem of affecting the screening efficiency due to large particles blocking the mesh holes.

[0007] Preferably, the knocking assembly includes a support seat, a driving member, and a cam, the driving member and the cam being mounted on one side of the screen frame through the support seat, the driving member driving the cam to rotate, and the cam being located on one side of the screen frame.

[0008] Preferably, a bumper block is arranged at the position of the screen frame close to the knocking assembly.

[0009] Preferably, the mounting assembly includes two mounting beams, the two mounting beams being respectively arranged on the upper and lower sides of the screen frame and clamping the screen frame, and the two ends of the two mounting beams being detachably mounted.

[0010] Preferably, the connecting block and the two clamping plates are arranged on both sides of the screen, and the two clamping plates are detachably mounted on the screen and the mounting beam through the connecting block.

[0011] Preferably, the buffer assembly comprises an elastic member and two limiting seats, and the elastic member is mounted between the ground and the mounting assembly through the two limiting seats.

[0012] Preferably, the number of the mounting assembly and the buffer assembly is respectively set as several groups.

[0013] Preferably, the screen disc further comprises a pressing plate frame, and the screen is detachably mounted on one side of the bottom of the screen frame through the pressing plate frame.

[0014] In general, the present application has the following advantages:

[0015] 1. The screen anti-blocking structure can avoid dolomite blocking, and when large particles block the screen, the cam intermittently knocks the screen disc, so that the large particles can be shaken out of the mesh of the screen, so that smaller particles can pass through, and the problem of affecting the screening efficiency caused by large particle blocking the mesh is solved.

[0016] 2. When the cam knocks the screen disc, the buffer assembly is arranged to buffer the screen disc, thereby facilitating to ensure the stability of the screen disc movement, and thereby reducing the possibility of failure of the screen disc and the mounting seat.

[0017] 3. The arrangement of the anti-collision block of the screen anti-blocking structure plays a protective role for the screen frame, thereby reducing the possibility of damage of the screen frame caused by collision.

[0018] 4. When more dolomite particles are located above the screen, the arrangement of the connecting block and the two clamping plates plays a supporting role for the middle part of the screen, thereby reducing the possibility of excessive deformation of the screen.

[0019] 5. When the screen is deformed too much or the screen disc needs to be cleaned, the detachable mounting of the mounting assembly and the pressing plate frame facilitates the workers to disassemble the screen, so as to clean or replace the screen. BRIEF DESCRIPTION OF DRAWINGS
