Self-cleaning sludge refining equipment

Abstract

The invention provides self-cleaning sludge refining equipment, and relates to sludge treatment equipment, particularly to improvement of sludge treatment equipment. The equipment has an ingenious structure, can clean broken stones and other impurities accumulated among multiple sets of rollers in time, and comprises a material collecting bin, wherein a pair of rollers are arranged below the material collecting bin, the sludge refining equipment further comprises a pair of vertical plates and a cleaning assembly, the pair of the rollers rotationally bear against between the pair of the vertical plates through rotating shafts, and are attached to each other, the cleaning assembly comprises a guide rail, a sliding block, a pulley and a cleaning tool bit, both ends of the guide rail fixedly bear against between the pair of the vertical plates, the cross section of the sliding block is an annular shape with a notch in the top, the sliding block is arranged on the outer side of the guide rail in a sleeved manner, the pulley is hinged into the notch of the sliding block, a motor is arranged in the pulley, and the bottom end of the pulley is attached to the guide rail. The service life ofthe equipment of the invention is prolonged, and the fault that the equipment is stuck due to too many impurities is avoided.

Description

technical field [0001] The invention relates to sludge treatment equipment, in particular to an improvement of sludge treatment equipment. Background technique [0002] At present, in the process of sewage treatment, a by-product, sludge, will be produced. The components of sludge include various substances, including bacterial cells, colloids and various microorganisms. At present, the discharge of urban sludge in my country has reached 10 million tons, and it is growing at a rate of 10% every year. This undoubtedly brings great harm to the environment. Come a lot of burden and pressure. The existing municipal sludge contains organic matter, nitrogen, potassium and other trace elements. Organic matter is not stabilized and is prone to decay. Nutrient elements and heavy metal substances will also cause secondary pollution. [0003] Therefore, this requires water treatment of sludge. The current treatment methods include gravity sedimentation, mechanical dehydration and ul...

AI Technical Summary

Problems solved by technology

[0004] The prior art discloses the method of ultrasonic dehydration of sludge, but the simple ultrasonic dehydration method has a certain effect on removing water, but because there are many sundries in the sludge, the simple ultrasonic dehydration method is not suitable for the later stage. Sludge treatment and resource recovery and reuse are unfavorable

[0005] Therefore, this requires a kind of sludge pretreatment equipment to solve the defects of sludge with many impurities and unbalanced particle size.

[0006] Therefore, someone proposed a solution to roll the sludge with multiple sets of rollers, but in actual use, we found that there are many impurities in the sludge, especially some hard impurities such as crushed stones mixed into the sludge After that, it will be accumulated between multiple sets of rollers, and in serious cases, multiple sets of rollers will be directly stuck, resulting in the failure of the equipment to work normally.
