Embodiment Construction

[0024] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.

[0025] A vehicle-mounted movable sewer dredging device includes a vehicle 1 and a carriage 3, the vehicle is a vehicle-mounted drive device, and a sludge treatment device is installed in the carriage. The sludge treatment device of the present invention adopts a multi-unit combined design and is installed on the vehicle pallet in the compartment, including an extraction unit, a screening unit, a dosing unit, a dehydration and drying unit, a deodorization unit, and a dewatered sludge unit. The collection unit, the wastewater treatment and discharge unit, and the extraction unit are composed of a twisted suction head 18 installed at the end of the mud suction pipe and a self-priming sludge pump 5. The twisted sucti...

Abstract

The invention relates to a vehicle-mounted mobile sewer dredging device, which comprises a vehicle and a carriage, wherein the carriage is arranged on a tray on the rear part of the vehicle; a sludge treatment device is arranged in the carriage; and the sludge treatment device comprises an extraction unit, a screening unit, a feeding unit, a dehydrating and drying unit, a deodorizing unit, a wastewater treatment and discharge unit and a dehydrated sludge collecting unit. The advanced sludge treatment device is combined, so the operation is more convenient and quicker, mobile operation can be realized and the treatment efficiency is improved; and the water content of the dehydrated and dried sludge is controlled at below 40 percent, so the sludge can fully meet self-maintained continuous combustion and is also convenient for sealing storage and long-distance transport. Objects with large size can be prevented from entering a dehydrating system during sludge treatment so that normal operation of the device is ensured.

Description

technical field [0001] The invention belongs to the field of municipal environmental sanitation engineering and relates to pipeline dredging, in particular to a vehicle-mounted movable sewer dredging device. Background technique [0002] In urban sanitation work, it is necessary to regularly remove garbage, sludge, etc. in the sewer to ensure the smooth flow of the sewer. With the rapid development of urban construction in our country, the length of urban sewers has also increased rapidly, and the dredging work of sewers has become more and more arduous. The composition of sewage sludge is complex. In addition to containing a large amount of water, it also contains a large amount of organic matter, refractory organic matter, various trace elements, pathogenic microorganisms and parasite eggs, heavy metals and salts. The harmless and resource utilization of complex urban sewer sludge has become a new difficulty and challenge in the comprehensive environmental management work...
