Description

Technical Field

[0001] This utility model relates to the field of gravity dust transportation technology, and in particular to a gravity dust conveyor belt sealing and dustproof curtain. Background Technology

[0002] Gravity ash is a solid waste generated during the blast furnace ironmaking process. During blast furnace ironmaking, impurities in the ore (such as lead and zinc) are reduced to vapor, which, along with fine dust from the ore, coke, flux, etc., is carried out of the furnace with the blast furnace gas. The dry coarse dust collected by the gravity dust collector in the blast furnace gas dust removal and purification system is gravity ash. Its particles are relatively large, with a high metal content, reaching over 60%, and a bulk density of 1.2-1.8 t / m³. Its main components include oxides of iron, carbon, silicon, calcium, zinc, etc., and it also contains alkali metal elements such as potassium and sodium.

[0003] In daily work, it was found that during the transportation of gravity dust, some conveyors have a shell on the upper part, but the sides of the conveyor are exposed. When transporting gravity dust, smoke and dust easily overflow from the sides. This not only directly causes serious pollution to the site environment, making the work area filled with dust and affecting the quality of the working environment, but also requires workers to regularly clean the ground and the area around the equipment where the overflowing smoke and dust accumulates, increasing the workers' extra workload. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where the sides of the conveyor are exposed, and when transporting gravity ash, dust easily overflows from both sides, which not only directly causes serious pollution to the site environment, but also requires workers to clean up, increasing the workload. Therefore, a dustproof curtain for sealing gravity ash conveyor belt is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a gravity-fed dustproof curtain with a conveyor belt, comprising a transport frame, wherein rollers and multiple support shafts are rotatably connected to the inner wall of the transport frame, a transport belt is mounted on the rollers and multiple support shafts, a shielding device is provided on the surface of the transport frame, the shielding device includes a mounting sleeve fixed to the surface of the transport frame, two mounting blocks are inserted into the inner wall of the mounting sleeve, a positioning part is provided on the mounting sleeve for positioning the mounting blocks, and multiple supports are fixedly connected to the surface of the mounting blocks. The support block has a shielding curtain on one side. Multiple inserts are fixedly connected to the surface of the shielding curtain. The inserts are inserted into the inner wall of the support block. The inner wall of the mounting block is provided with a limiting part to limit the position of the inserts and the shielding curtain. Through the above components, the inserts are inserted into the support block, so that the shielding curtain fits against the inner side of the support block and is limited by the limiting part. Then, two mounting blocks are inserted into the mounting sleeve and positioned by the positioning part. The shielding curtain can cover the exposed sides of the conveyor belt and reduce the phenomenon of dust overflow.

[0006] Preferably, the limiting part includes a sliding plate that is slidably connected to the inner wall of the mounting block. Multiple locking blocks are fixedly connected to the surface of the sliding plate. The surfaces of the support block and the insertion block are respectively provided with grooves and slots. The locking blocks are respectively inserted into the inner walls of the grooves and slots. Through the above components, after the curtain is inserted into the support block through the insertion block, the sliding plate can then drive the locking blocks to be inserted into the grooves and slots, thereby limiting the insertion block.

[0007] Preferably, the inner wall of the mounting block is rotatably connected to a screw, which is threadedly connected to the inner wall of the slide plate. Through the above-mentioned components, the screw can be rotated, thereby driving the slide plate and the locking block to move and adjust.

[0008] Preferably, the positioning part includes two positioning shafts fixed in the inner wall of the mounting sleeve. The positioning shafts are inserted into the inner wall of the mounting block. Two locking rods are slidably connected to the inner wall of the mounting sleeve. The locking rods are inserted into the inner wall of the mounting block. With the above components, when positioning, the mounting block is inserted into the mounting sleeve, the positioning shafts are inserted into the inner wall of the mounting block, and then the locking rods are slid to insert into the inner wall of the mounting block, thus realizing the installation operation.

[0009] Preferably, a spring is fixedly connected to the side of the clamping rod corresponding to the inner wall of the mounting sleeve. There are two springs. Through the above-mentioned components, the springs can ensure the stability of the clamping rod when it is inserted into the inner wall of the mounting block, thereby improving the positioning effect.

[0010] Preferably, the insert is T-shaped.

[0011] Preferably, the blind curtain is made of rubber.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a shielding device, two mounting blocks are positioned in the mounting sleeve by the positioning part. The support block can drive the shielding curtain to slightly contact the conveyor belt, thereby shielding the exposed parts on both sides. After effectively blocking the overflow of smoke and dust, the dust pollution in the work area is significantly reduced, and workers are no longer required to clean up the dust accumulated due to the overflow of smoke and dust on a regular basis, eliminating the extra cleaning task.

[0013] In this invention, the limiting part, in conjunction with the insert block, enables the curtain to be quickly disassembled, facilitating subsequent maintenance and replacement.

[0014] In this invention, the rubber curtain can deform slightly as the conveyor belt moves, thus improving the sealing effect. Attached Figure Description
