A sludge cleaning device for river sewage treatment

Abstract

A sludge cleaning device for river sewage treatment, including a sludge cleaning device. The sludge cleaning device includes vertical plates, and the vertical plates are connected with arc-shaped plates. There is a cleaning cylinder under the arc-shaped plates. The side wall of the cleaning cylinder has a first blind hole. There is an insertion rod in a blind hole, the front and rear side walls of the arc-shaped plate are connected to the guide plate, the rear side wall of the vertical plate is connected to the motor, the front and rear side walls of the arc-shaped plate are provided with support rods, and the bottom of the support rod is provided with a walking wheel assembly. A fifth through hole is arranged on the front side wall of the front side wall, and a dredge pipe is connected in the fifth through hole, and the dredge pipe is connected with a dredge pump device. Through the rotation of the cleaning cylinder, the device drives the insertion rod to rotate. During the rotation of the insertion rod, only the sludge at the bottom can be extracted, which effectively prevents the upper side of the sludge from being extracted and affects the ecological environment in the river. Due to different The width of the river is not consistent, the operator can set up multiple sets of this device to clean up the mud at the bottom of the river, and the mud on the lower side of each set of devices can be pumped by the dredge pump device.

Description

technical field [0001] The invention belongs to the field of sludge cleaning devices, in particular to a sludge cleaning device for river sewage treatment. Background technique [0002] With the continuous development of industry and production, more and more factories have sprung up. Many companies choose the factory site in the suburbs near the river because of the cheap land price and the convenient discharge environment of the treated waste gas and wastewater. However, some of them are not good. Enterprises and companies will discharge untreated or treated wastewater that has not reached the standard into rivers for economic benefits. There are still a large number of organic pollutants and heavy metal pollutants in untreated wastewater. These pollutants are difficult to degrade and have relatively high toxicity. If it is large, it will not only cause a large number of algae plants to multiply on the river, but also cause the oxygen content in the river to drop, which wi...

[0002] With the continuous development of industry and production, more and more factories have sprung up. Many companies choose the factory site in the suburbs near the river because of the cheap land price and the convenient discharge environment of the treated waste gas and wastewater. However, some of them are not good. Enterprises and companies will discharge untreated or treated wastewater that has not reached the standard into rivers for economic benefits. There are still a large number of organic pollutants and heavy metal pollutants in untreated wastewater. These pollutants are difficult to degrade and have relatively high toxicity. If it is large, it will not only cause a large number of algae plants to multiply on the river, but also cause the oxygen content in the river to drop, which will seriously affect the ecological environment in the river. After the aquatic products are caught and eaten by people, the pollutants will enter the human body, causing serious harm to the growth and health of the human body; at the same time, the accumulation of silt in the river will also affect the important livelihood tasks such as flood control and drainage, water supply and navigation. , the treatment of accumulated sludge can not only significantly improve the production conditions and living environment of the masses, but also promote the rapid and sustainable development of the economy and society; traditional sludge cleaning machinery usually digs the sludge directly, and then transports the sludge to Designate the treatment site, because the surface layer of silt in the river not only contains the nutrients that many organisms rely on for survival, but also the organisms in the river will lay their eggs on the surface of the silt. Traditional silt cleaning machinery usually digs away the silt on the surface and directly Affect the ecological balance in the river and destroy the ecological environment of the river
