Movable-type sewer sludge disposal vehicle

Abstract

The invention discloses a movable-type sewer sludge disposal vehicle. The movable-type sewer sludge disposal vehicle comprises a whole system program operation monitoring unit and a flatbed truck andfurther comprises an automatic sludge taking unit, an automatic discharging unit, a sludge vibrating screening unit, a sand-stone grading washing unit and a fine sand washing dehydration unit which are arranged on the flatbed truck and sequentially connected. The automatic sludge taking unit is a grab-bucket-type sludge taking unit and comprises a grab bucket and a mechanical arm, and the grab bucket is mounted at one end of the mechanical arm. The sand-stone grading washing unit comprises a sand washing machine, wherein the sand washing machine is a hydraulic ultrasonic sand-stone grading washer. According to the movable-type sewer sludge disposal vehicle, sludge which is generated in an area in a dispersed mode can be disposed on site into municipal solid waste, organic sundries, inorganic sand-stone and tail water, and thus the sludge is subjected to reduction and harmless disposal in the sludge producing area.

Description

technical field [0001] The invention belongs to the technical field of municipal public services, and in particular relates to a mobile ditch sludge disposal vehicle. Background technique [0002] As an important part of the urban drainage system, the drainage pipe is responsible for the collection and transportation of urban domestic sewage, industrial wastewater and rainwater. It is one of the important urban infrastructures to ensure the normal production, life and flood control of the city. [0003] When domestic sewage, rainwater or industrial sewage flows into sewage pipes, rainwater pipes or rain-sewage mixed-flow pipes, a certain amount of domestic garbage, kitchen waste, ground sediment or industrial waste will inevitably be carried into the pipes, and hoarding or blockage will occur in the pipes , reducing the effective delivery capacity of the pipeline. [0004] If the pipeline sewage is seriously blocked, the sewage will overflow from the manhole cover, and the ...

AI Technical Summary

Problems solved by technology

[0013] ⑴The processing station involves construction land acquisition, infrastructure construction, installation and operation of electromechanical equipment, and road construction for vehicles entering and exiting, etc., and the one-time investment is high

[0014] ⑵Limited service radius

Due to the complex composition and high water content of trench sludge, it is not suitable for long-distance transportation. Therefore, the service radius of the treatment station is limited to a certain extent

[0015] (3) It is difficult to select the site of the processing station, and it is difficult to implement the site of the processing station in the urban area, especially in the old urban area

[0016] (4) Hydraulic cleaning of sand and gravel, the removal rate of organic matter wrapped in sand and gravel is limited, the burning loss rate is 5-10%, and there is still a foul smell, which cannot be used for bulk building materials and can only be put into landfills

[0017] (5) The remaining organic tail water of the treatment station is discharged into the underground pipe network and fixed, and it is very easy to block the drainage pipe here
