a negative pressure filter

Abstract

The invention discloses a negative pressure filter, which includes a filter tube, a filter device and a controller. There is an oil cylinder, and the power end of the oil cylinder presses the filter device on the working side of the pressure measurement and sealing mechanism; one side of the filter tube is connected to a liquid outlet pipe, and the side of the filter pipe far away from the liquid outlet pipe is provided with an anti-blocking sewage discharge The anti-blocking sewage mechanism is connected with a liquid inlet pipe, and the vacuum water tank is provided with a discharge port and a pressure gauge. The anti-blocking sewage mechanism is connected with the filter pipe and cooperates with the filter device. The controller Electrically connect the pressure gauge, vacuum pump, oil cylinder and pressure measuring sealing mechanism; a negative pressure filter of the present invention generates negative pressure through the vacuum pump, so that the waste water can quickly pass through the filter device, and the rapid removal efficiency of particulate matter in the waste water is improved, thereby Accelerate the filtration speed and can improve the recycling rate of waste water.

Description

technical field [0001] The invention belongs to the field of filter devices, and in particular relates to a negative pressure filter. Background technique [0002] At present, there are three main sources of air pollution: Industry: Industry is an important source of air pollution. The pollutants discharged into the atmosphere by industry are various and complex in nature, including smoke, sulfur oxides, nitrogen oxides, organic compounds, Halides, carbon compounds, etc., some of which are smoke and some are gases; domestic stoves and heating boilers: a large number of civilian stoves and heating boilers in cities need to consume a lot of coal, and coal will release a lot of dust, sulfur dioxide, carbon dioxide, and carbon monoxide during combustion Such harmful substances pollute the atmosphere, especially when heating in winter, often make the polluted area filled with smog and make people cough, which is also a source of pollution that cannot be ignored; transportation: a...

Problems solved by technology

High-concentration organic wastewater has the characteristics of high concentration, complex composition, poisonous and harmful, and if it is directly discharged into the water body without treatment, it will seriously pollute the water body environment

[0004] However, after water degradation, it needs to be comprehensively treated according to its characteristics, such as biodegradation and chemical degradation, but these degradation methods cannot meet the existing production speed, and most of them are caused by the inability to control the concentration of harmful substances in wastewater during the degradation process. Most of the existing equipment directly transports wastewater to the degradation tank. Although the direct degradation has a fast wastewater transport speed and does not affect the exhaust gas emission efficiency, the wastewater is prone to exceed the discharge standard; and due to the harmful The substance content is not the same, so that a single filter device cannot complete its filtering task
