Sludge cleaning device for river sewage treatment

Abstract

The invention discloses a sludge cleaning device for river sewage treatment. The sludge cleaning device for river sewage treatment comprises a sludge cleaning device body; the sludge cleaning device body comprises vertical plates; an arc-shaped plate is connected between the vertical plates; a cleaning cylinder is arranged below the arc-shaped plate; first blind holes are formed in the side wall of the cleaning cylinder; inserting rods arranged in the first blind holes; a guide plate is connected to the front side wall and the rear side wall of the arc-shaped plate; a motor is connected to the rear side walls of the vertical plates; supporting rods are arranged on the front side wall and the rear side wall of the arc-shaped plate; walking wheel assemblies are arranged at the bottoms of the supporting rods; a fifth through hole is formed in the front side wall of one vertical plate; and a mud suction pipe is connected into the fifth through hole and connected with a mud suction pump device. The device drives the inserting rod to rotate through rotation of the cleaning cylinder; it is guaranteed that only sludge at the bottom can be extracted in the rotating process of the inserting rods; and the situation that the sludge on the upper side is extracted, and consequently the ecological environment in a river is affected is effectively avoided; widths of different river channels are different, so that operators can set multiple sets of the device to comprehensively clean sludge at the bottom of a river channel; and the sludge on the lower side of each set of device can be pumped through the sludge suction 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
