Truck for removing sludge from inspection well

Abstract

The invention relates to a truck for removing sludge from an inspection well, which belongs to the technique of mechanically removing the sludge from the inspection well for the urban pipe network. When the sludge in the inspection well is removed, an inspection well cover is opened. The truck power is started by a microcontroller to start an oil pump and drive a soft shaft. Meanwhile, a sludge conveying flexible pipe is driven to move an oil cylinder upwards, downwards, leftwards, rightwards, frontwards and backwards, and the soft shaft, the sludge conveying flexible pipe, a sludge pump and a stirring head are correctly conveyed in the inspection well. According to size of the inspection well, a program that has been set by the microcomputer controller is selected. Under the control of the program, the sludge deposited in the inspection well is stirred in a flowing shape by the stirring head spirally from top down, and the sludge in the flowing shape is conveyed into a sludge storage tank by effect of an impeller of the sludge pump. The waste water in the sludge storage tank is discharged through a waste water outlet after continuous operation and sludge deposition, so that the sludge storage tank can store the sludge maximally. After the sludge is stored in the whole sludge storage tank, the sludge storage tank is conveyed to a named place where the sludge is discharged. Finally the sludge deposited on the bottom of the sludge storage tank is pushed out from a sludge discharge outlet by a sludge discharge spiral rod.

Description

technical field [0001] The invention relates to a mechanized technology for removing sludge from inspection wells in urban pipe networks, in particular to a vehicle for removing sludge from inspection wells. Background technique [0002] At present, most of the silt removal operations in urban manholes are still dug manually, which is labor-intensive and unsafe. Because there are various toxic gases in the inspection well, workers will be poisoned if they do not operate properly. If the cleared silt cannot be transported away in time, it will emit a foul smell and cause secondary pollution to the urban environment. The mechanically operated vacuum suction truck cannot suck out the sludge deposited at the bottom of the inspection well. Even if it is washed with a high-pressure water gun, the operation is cumbersome, the labor intensity is high, and the efficiency is low. After being washed by the high-pressure water gun, most of the waste water sucked by the vacuum suction...

Problems solved by technology

Moreover, the silt in the mud storage tank will settle at the bottom of the mud storage tank after being bumped during transportation, making it difficult to unload.

For this reason, the current urban inspection well removal operation has short continuous operation time, low benefit, high cost, and cumbersome operations.
