Abstract

The invention relates to the technical field of sewage precipitation tank washing and crude oil recycling, in particular to a sewage precipitation tank online washing machine, a device for online washing of the sewage precipitation tank and recycling of crude oil and a using method. The sewage precipitation tank online washing machine comprises a car body, a washing device, a small car power transmission device, a power device of the cleaning device and a motor control device. Two front wheels and two back wheels are installed at the bottom of the car body, a cleaning device installation support is fixedly installed at the front end of the car body, and a first motor and a second motor are fixedly installed in the car body. The cleaning device comprises a high pressure flexible pipe, a cleaning nozzle, an oscillating rod, a sliding block, a connection rod, a crank handle and a transmission shaft. The sewage precipitation tank online washing machine is reasonable and compact in structure and achieves the effect that a cleaning small car walks and steers and in the tank, and the cleaning nozzle swings in reciprocating mode by controlling the three motors in the sewage precipitation tank online washing machine. Produced sewage is directly absorbed out of the tank through the siphoning effect, so that the sewage precipitation tank online washing machine can conduct online cleaning. The sewage precipitation tank online washing machine is high in working efficiency and reduces labor intensity, safety hazards and manual cost.

Description

technical field [0001] The invention relates to the technical field of sewage settling tank cleaning and crude oil recovery, and relates to an on-line cleaning machine for sewage settling tanks, an on-line cleaning and crude oil recovery device for sewage settling tanks and a method for using them. Background technique [0002] During the long-term storage and transportation of sewage settling tanks, a small amount of mechanical impurities, sand, soil, heavy metal salts, and heavy oily components such as paraffin and asphaltene in the oil will naturally settle due to the difference in specific gravity and accumulate at the bottom of the tank , forming a colloidal material layer, which is the bottom sludge of the sewage tank settlement tank. The tank bottom sludge is rich in organic matter and its composition is very complex, so it cannot be directly discharged for disposal. This part of the sludge has little impact on the system in a short period of time after it settles, b...
