Description

Technical Field

[0001] The utility model relates to the technical field of sulfur concentrate acid-making slag discharge components, in particular to a low-dust slag discharge and conveying component. Background Art

[0002] In the sulfur concentrate acid production process, due to the particularity of the preparation process, a large amount of waste slag is usually discharged. The slag discharge process is a crucial link, which is not only related to production efficiency and product quality, but also directly affects environmental protection and worker health.

[0003] Traditional slag discharge methods often use direct discharge operations. During specific operations, conveyor belts are generally used to transport waste slag. This type of discharge is often accompanied by high dust emissions, which not only causes serious pollution to the environment, but also increases the occupational health risks of workers. In addition, high-dust environments will accelerate the wear of conveying equipment, shorten equipment service life, and increase maintenance costs. At the same time, dust accumulation may also cause equipment failures, affecting the normal operation of the production line.

[0004] In addition, the use of conveyor belts for conveying and slag removal is not conducive to achieving low-dust slag removal because the conveyor belt is basically exposed to the outside and lacks components that can handle dust. In view of this, we have proposed a low-dust slag removal and conveying component. Utility Model Content

[0027] Specifically, a dust hood 24 is fixedly installed on the top cylinder of the discharge end of the screw conveyor 20, so that the granular waste can fall directly down along the end of the screw conveyor 20; a dust suction pipe 25 is fixedly installed on the top of the dust suction hood 24, and a dust collection cylinder 251 is fixedly installed on the top of the dust collection pipe 25.

[0028] In this embodiment, inclined plates 221 are fixedly installed on the inner walls of the left and right sides of the top cover of the feed hopper 22. The inclined plates 221 are set to be tilted downward at 45 to 60 degrees, so that the waste residue falls toward the center of the feed hopper 22 more smoothly.

[0029] Specifically, a transparent plate 271 is provided on the top of the dust collection cylinder 251 . The transparent plate 271 is a transparent plate structure. The transparent plate 271 is used for observation operation to observe the amount of dust in the dust collection cylinder 251 .

[0030] Furthermore, a limiting ring 27 is fixedly installed on the transparent plate 271, and a fixing ring 252 is fixedly installed on the top cylinder of the dust collector 251. The limiting ring 27 is fixedly installed on the top surface of the fixing ring 252 by a plurality of fastening bolts, which is convenient for fixed installation and disassembly operations. After the transparent plate 271 is removed, the top of the dust collector 251 is exposed to the outside, and the fan 261 and the inner wall of the dust collector 251 can be cleaned.

[0031] In addition, two symmetrical front and rear rotating shafts 231 are rotatably connected between the left and right side plates of the feed hopper 22, and a crushing roller 23 is fixedly mounted on the rotating shaft 231.
