Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, and particularly relates to a drying device for reducing the amount of oily sludge. Background Art

[0002] Sludge treatment is a process of reducing, stabilizing, and rendering harmless sludge. The higher the degree of sewage treatment, the more sludge residues will be generated that need to be treated. Unless land treatment or sewage pond treatment is used for sewage treatment, general sewage treatment plants must be equipped with sludge treatment facilities.

[0003] At present, when the oily sludge treatment equipment on the market treats sludge, it is necessary to dry the sludge outdoors for a long time, and then granulate it after drying. The treatment steps are cumbersome, reducing the dehydration efficiency of the sludge. There is no device for facilitating the improvement of the efficiency of removing oil from the sludge. It is necessary to add an emulsifier to react with the oil, and then gradually remove it. The oil removal efficiency is low, reducing the working efficiency of users. Summary of the Utility Model

[0004] The utility model provides a drying device for reducing the amount of oily sludge, aiming to solve the problem in the prior art that it is necessary to add an emulsifier to react with the oil and then gradually remove it, with low oil removal efficiency and reduced working efficiency of users.

The inner wall of the drying box is fixedly connected with electric heating tubes. The outer wall of the explosion-proof combustion cylinder is communicated with a second feeding hopper, and the inner wall of the explosion-proof combustion cylinder is slidably connected with an equipment frame. The inner wall of the equipment frame is fixedly connected with a guide mesh plate, and there are two equipment frames. The inner wall of the explosion-proof combustion cylinder is fixedly connected with a combustion pipe, and the combustion pipe is located below the equipment frame. The outer wall of the feeding pipe is provided with a controller, and the conveying motor, the conveyor belts, and the electric heating tubes are electrically connected to the controller.

[0006] Preferably, a baffle is hinged to the inner wall of the explosion-proof combustion cylinder.

[0007] Preferably, connecting plates are fixedly connected to the outer walls of the two equipment frames, and a spring is fixedly connected to the outer wall of the explosion-proof combustion cylinder.
