Description

Technical Field:

[0001] The utility model relates to the technical field of belt conveying equipment, and particularly relates to a device for centrally collecting and cleaning returned sludge materials of a large-inclination belt. Background Art:

[0002] A large-inclination belt is a new type of conveying machinery, which is suitable for continuously conveying bulk materials at a large inclination angle or vertically. The conveying angle is between 0° and 90°, with a small floor area and a large conveying capacity. Group edges and retaining edges are installed on the belt, and there are transverse partitions in the middle, effectively preventing the materials from sliding backward. However, there is currently a serious drawback, that is, when the incoming materials are relatively moist with a large water content, it is particularly easy for the materials to stick in the buckets formed by the transverse partitions of the large-inclination belt.

[0003] At present, ordinary cleaners generally include a striker and a felt roller cleaner, both of which cannot clean thoroughly, resulting in the sticky materials and water forming mud. It can only be cleaned by water flushing. However, the sludge water flushed down spills under the large-inclination belt, causing serious material accumulation under the belt. Moreover, relying on the force of water flushing, the sludge water flows along the slope of the belt all the way to the tail of the machine. However, the equipment cannot be cleaned during the rotation process. After the machine stops, it needs to be raked out manually with tools and then cleaned, resulting in an increase in the number of shutdowns during the production process, great cleaning difficulty, a waste of a large amount of labor, and at the same time, a significant increase in the danger coefficient of employees during the cleaning process. Content of the Utility Model:

[0004] The purpose of the utility model is to provide a device for centrally collecting and cleaning returned sludge materials of a large-inclination belt, so as to solve the problems that the post workers need to stop the machine multiple times during the production process to clean the accumulated materials and the cleaning difficulty is great.

[0005] The utility model is implemented by the following technical solutions: A device for centrally collecting and cleaning returned sludge materials of a large-inclination belt, which includes a bottom plate and a flushing nozzle; the bottom plate is fixed on the frame under the large-inclination belt, and the flushing nozzle is installed along the width direction on the bottom plate under the highest point of the large-inclination belt; it also includes an aggregate bin, a water collection tank, and a material guiding trough; the aggregate bin and the water collection tank are sequentially installed and fixed along the conveying direction of the large-inclination belt on the bottom plate at the low position of the large-inclination belt, and the tops of the aggregate bin and the water collection tank are open; a water draining grate is installed on the top surface of the water collection tank, and the material guiding trough is installed on the bottom plate between the water draining grate and the flushing nozzle; a downwardly inclined guiding plate is fixed on the inner wall of one side of the top of the aggregate bin adjacent to the water collection tank, and a secondary water draining grate plate is installed at the bottom of the aggregate bin; water guiding pipes are communicated with the bottoms of both the water collection tank and the aggregate bin, and a collecting water pump pit is arranged on the ground below the water guiding pipes.

[0006] Further, a vibration motor is installed and fixed on the bottom surface of the guiding plate.

[0007] Furthermore, the bottom plate is a profiling structure with the same shape as the large-inclination belt.

[0008] Furthermore, the bottom of the aggregate box is inclined downward corresponding to the water guide pipe.

[0009] Furthermore, the orifice width of the water draining grate and the secondary water draining grate plate is 0.5 mm.

[0010] Furthermore, the side wall of the aggregate box is provided with an observation port and a cleaning port.

[0011] Advantages of the present utility model: The washing water sprayed by the washing nozzle is used to wash the materials adhered to the return belt. The sludge water washed by the washing nozzle flows along the material guide groove to the water collection tank. After the materials and water are separated by the water draining grate, the water will pass through the water draining grate and enter the water collection tank. The drained materials continue to fall downward along the material guide plate into the aggregate box. The water in the water collection tank and the water in the aggregate box after passing through the secondary water draining grate plate respectively flow directly into the collection water pump pit on the ground through the corresponding water guide pipes. The materials in the aggregate box are centrally cleaned through the cleaning port. By the present utility model, the washed sludge water is separated into water and materials, and the water and materials are respectively centrally processed, greatly reducing the cleaning difficulty, reducing the labor intensity of employees. The post workers can clean without stopping the machine, reducing the number of equipment shutdowns, and effectively reducing various safety risks that occur when employees clean the materials.
