Description

TECHNICAL FIELD

[0001] The utility model relates to sludge dewatering technical field, concretely is sludge centrifugal dewatering equipment. BACKGROUND

[0002] In the process of the continuous development of urban sewage treatment and industrial wastewater treatment, the effective treatment of sludge is increasingly critical, and the sludge centrifugal dewatering equipment, as the core treatment equipment, undertakes the heavy responsibility of reducing the moisture content of sludge and facilitating subsequent disposal, and its principle is to promote the separation of solid and liquid in sludge by centrifugal force generated by high-speed rotation.

[0003] However, the traditional equipment has obvious shortcomings when facing complex and diverse sludge characteristics. When encountering sludge raw materials with high viscosity, such as sludge generated in the printing and dyeing and papermaking industries, the sludge contains a large amount of colloidal substances and viscous polymers, and the internal structure is compact. The single centrifugal dewatering method has poor effect, and cannot fully break the viscous bonds in the sludge. The centrifugal force generated by high-speed rotation cannot effectively throw out the water in the sludge, resulting in high moisture content of the dewatered sludge. This not only increases the subsequent treatment cost, but also affects the overall sludge treatment efficiency. Therefore, it is urgent to solve the above problems by using sludge centrifugal dewatering equipment. SUMMARY

[0004] The utility model aims at providing sludge centrifugal dewatering equipment to solve the problem of poor dewatering effect of the traditional sludge centrifugal dewatering equipment when encountering sludge raw materials with high viscosity.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a sludge centrifugal dewatering equipment, comprising a main box, a separation barrel rotatably connected inside the main box, and a centrifugal extrusion assembly arranged inside the separation barrel.

[0006] The centrifugal extrusion assembly comprises a mounting column rotatably connected to the inner wall of the separation barrel, the mounting column is rotatably connected to the inner wall of the main box, the inner wall of the mounting column is slidably connected to a plurality of sliding columns, the two ends of the plurality of sliding columns are fixedly connected to the same extrusion barrel, two springs are sleeved on the surface of the sliding column, one end of the spring is fixedly connected to the inner wall of the extrusion barrel, and a counterweight is sleeved on the surface of the sliding column.

[0007] Preferably, the inner wall of the main box is rotatably connected to a connecting pipe, the upper end of the connecting pipe is fixedly connected to the bottom surface of the separation barrel, a first spur gear is fixedly connected to the surface of the connecting pipe, a second spur gear is fixedly connected to the surface of the mounting column, a Z-shaped plate is fixedly connected to the bottom surface of the main box, a connecting column is rotatably connected to the inner wall of the Z-shaped plate, a third spur gear is fixedly connected to the surface of the connecting column, and a fourth spur gear is rotatably connected to the surface of the connecting column.

[0008] Preferably, the third spur gear is meshed with the first spur gear, and the fourth spur gear is meshed with the second spur gear. The number of teeth of the third spur gear and the first spur gear is greater than the number of teeth of the fourth spur gear and the second spur gear.

[0009] Preferably, the inner wall of the main body box is provided with a sliding groove, and a plurality of rotating beads are rotatably connected to the inner wall of the sliding groove, and the surfaces of the plurality of rotating beads abut against the surface of the separation barrel.

[0010] Preferably, a motor is fixedly connected to the side wall of the Z-shaped plate, and the surface of the connecting column is fixedly connected to the output end of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The centrifugal extrusion assembly ensures that the mounting column rotates at high speed while the high-speed rotating separation tank centrifugally dewaters the sludge inside. The high-speed rotation of the mounting column causes the extrusion tank, counterweight, and sliding column to generate centrifugal force, which in turn drives the extrusion tank to move outward. The outward movement of the extrusion tank extrudes the sludge inside the separation tank, thereby facilitating faster dewatering of sludge with high viscosity. Attached Figure Description
