Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold slag machine technology, specifically to a dust collection device for a cold slag machine. Background Technology
[0002] A slag cooler, also known as a slag cooler, is mainly composed of a cylinder, a slag inlet box, a slag outlet box, a power transmission device, a base frame, and an electrical control system. Both the cylinder and the partition frame adopt a water-cooled wall structure, and slag guide plates are welded on the inner wall of the cylinder and the partition frame. It is a mechanical device used to cool and transport high-temperature slag materials, and is widely used in metallurgy, chemical industry, power industry and other industries. The main function of the slag cooler is to cool high-temperature slag materials to a certain temperature through a cooler and a conveying device, and then transport them to a designated location.
[0003] In the existing slag cooler, during continuous slag discharge, a large amount of fine ash is generated due to the repeated combustion of coal in the furnace. The fine ash is mixed with the slag and is discharged through the slag outlet after the slag cooler recovers heat. When the slag is discharged, the hot fine ash expands and forms dust. This dust will spread at the slag outlet of the slag cooler, causing pollution to the working environment. Although the slag outlet of the slag cooler can be cleaned by a dust collection device, the cleaning effect is limited, and it is time-consuming and labor-intensive. It is also inconvenient for workers to collect slag and ash, and it is also inconvenient to disassemble and replace the filter screen of the dust collection device. Therefore, a dust collection device for the slag cooler is proposed. Utility Model Content

The slag enters the processing box 4 through the discharge pipe 3. Dust is generated when the slag enters the processing box 4. The dust is sucked into the processing box 4 through the dust suction pipe 7 connected to the dust suction hood 8. The screen 9 on one side of the dust suction hood 8 prevents the slag from entering the dust suction hood 8 and causing blockage. The filter plate 10 inside the dust suction hood 8 filters particulate impurities in the dust to prevent the dust suction pipe 7 from being blocked. After dust removal, the slag enters the slag discharge box 6 at the bottom of the processing box 4 for slag discharge.
[0040] 2. By connecting the fan 12 to the dust suction pipe 7, the dust inside the processing box 4 is sucked in and transported to the collection box 11 for centralized collection.
