A sewage tank bottom removal device

Abstract

The invention discloses a sewage pool bottom sediment removing device. The device comprises a sewage pool, bottom sediments, an air source, a controller, an air inlet pipe, a floating lamp, a water inlet pipe, a blowdown pipe, a sludge pump, a chemical tank, a metering pump and a sludge stirrer. The sewage pool is provided with the water inlet pipe and the blowdown pipe, the water inlet pipe is communicated with the chemical tank through the metering pump, and the blowdown pipe is communicated with the blowdown pump through a pipeline; the air source and the controller are arranged outside the sewage pool, the sludge stirrer is communicated with the air source, and the top of the sludge stirrer is provided with the floating lamp. The sludge stirrer comprises a buoyancy tank, a pneumatic motor, an exhaust pipe, transmission shafts, a transmission wheel, a sludge stirring plate and sludge scraping plates. The pneumatic motor is integrally provided with an air inlet valve and an exhaust valve, the exhaust pipe is horizontally arranged all around the sludge stirrer, and the sludge stirring plate and the sludge scraping plates are arranged on the lower portion of the sludge stirrer. According to the sewage pool bottom sediment removing device, the pneumatic sludge stirrer is adopted, the pneumatic motor drives the sludge stirring plate and the sludge scraping plates, manual operation is not needed, the bottom sediment removing effect is good, the labor intensity is low, and operation is easy and convenient.

Description

technical field The invention relates to the technical equipment field of sewage treatment, in particular to a sewage tank bottom removal device. Background technique With the development of enterprises and the increase of population, the amount of domestic sewage and industrial sewage treatment is increasing. A large amount of solid matter will be deposited in various sewage treatment tanks after long-term continuous operation. The usual cleaning is to manually clean after releasing water, or Use the pump to pump out the sediment at the bottom of the pool. In the cleaning process, the labor intensity is high, the water resources are wasted, and it brings inconvenience to the water. As an important part of sewage treatment, the sewage pool needs a structure that is reasonable and easy to use. , Energy-saving and high-efficiency technical methods to effectively clean and maintain the bottom of the sewage tank. The disadvantages in the prior art are: the sewage pool usually ...

With the development of enterprises and the increase of population, the amount of domestic sewage and industrial sewage treatment is increasing. A large amount of solid matter will be deposited in various sewage treatment tanks after long-term continuous operation. The usual cleaning is to manually clean after releasing water, or Use the pump to pump out the sediment at the bottom of the pool. In the cleaning process, the labor intensity is high, the water resources are wasted, and it brings inconvenience to the water. As an important part of sewage treatment, the sewage pool needs a structure that is reasonable and easy to use. , energy-saving and high-efficiency technical methods to effectively clean and maintain the bottom of the sewage tank

The disadvantages in the prior art are: the sewage pool usually contains harmful and difficult-to-degrade organic compounds, which are prone to produce flammable and explosive gases, and manual cleaning is the most likely to cause casualties; although a sewage pump room is installed to remove the sewage However, the long-term sediment at the bottom of the sewage pool still needs to be removed manually on a regular basis, especially after the sediment is hardened, it is difficult to extract the hardened bottom and discharge it. At this time, it is necessary to manually turn the sediment at the bottom of the pool This method is not only labor-intensive, but also has poor decontamination effect
