Description

Technical Field

[0001] The utility model belongs to the field of coal mine machinery, and in particular relates to a tar slag chamber overturning and dumping device. Background Art

[0002] The gas purification process in the coking industry produces tar residue as a byproduct, which is a hazardous waste and therefore needs to be treated and discharged harmlessly. Some domestic coking plants use ultracentrifugal technology to dry the tar residue, and the dried tar residue is loaded into the tar residue box, which is then transported by forklift to the coal preparation process and mixed with coking coal, ultimately achieving harmless treatment of the tar residue. However, the existing equipment can only place the tar residue box next to the tar residue bin, and then manually shovel the tar residue (dry) in the tar residue box into the tar residue bin. During this process, the tar residue is easily scattered and pollutes the surrounding environment; and the site is accompanied by an unpleasant tar smell, which will have an adverse effect on the employees' physical and mental health; it also greatly increases the workload, and the company's employment costs increase accordingly.
