Embodiment Construction

[0017] The present invention is described in further detail below in conjunction with accompanying drawing:

[0018] A sludge magnetization dehydration treatment device, the treatment device is composed of a bracket 1, a magnetic force device, a telescopic heating type charging device, a hopper 8, a chemical sprayer 10, a sensor, and a sludge collector 17, wherein the telescopic heating type The charging device is composed of a water-bath heating cylinder 4 and a sludge charging bin 6, which is a sandwich cylinder. The water-bath heating cylinder 4 and the sludge charging bin 6 are a whole that can be expanded and sealed at the same time. The telescopic heating type charging device Positioning bolts are set on the outer wall surface, and when the length of the telescopic heating charging device reaches the requirement, tighten the positioning bolts for positioning. Temperature sensors are set in the water bath heating cylinder 4 and sludge charging bin 6, and moisture sensors a...

Abstract

The invention relates to a sludge magnetization dehydration treatment device, which belongs to the technical field of environmental geotechnical engineering. The magnetization dehydration treatment device is composed of a bracket, a magnetic force device, a telescopic heating charging device, a pipeline, a hopper, a chemical sprayer, a sensor, an outer circulation constant temperature water bath, a capillary water absorption time tester, and a sludge collector. The charging device and the variable distance magnetic device can realize the test of sludge dehydration performance with different magnetic field strength gradients; the external circulation constant temperature water bath can ensure that the sludge is heated evenly and the temperature control accuracy is high; the sensor, the chemical sprayer and the control system The connection can monitor data in real time and automatically regulate drug administration, which can improve work efficiency. The invention has reasonable design, simple structure and convenient manufacture, can determine the optimal combination parameters of sludge dehydration under the condition of multi-factor cooperative control, and has no secondary pollution in the sludge dehydration conditioning process, is easy to operate, consumes less energy, and has low cost.

Description

technical field [0001] The invention relates to a sludge magnetization dehydration treatment device, which belongs to the technical field of environmental geotechnical engineering. Background technique [0002] Sludge is a muddy substance with organic matter as the main component formed in the process of sewage treatment. It is a hydrophilic substance with a colloidal structure that is easy to rot and smell, with fine particles, low density, high water content but not easy to dehydrate. Sludge is dubbed an "environmental killer" because of its high water content, high organic matter content, high heavy metal content, and high germ content. Many countries in the world regard sludge as "dangerous goods." [0003] According to incomplete statistics, my country produces more than 30 million tons of wet sludge with a water content of 80% every year, and it is increasing at a rate of about 10% year by year. For a long time, from design to operation of my country's sewage treatmen...
