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

Embodiment 1

[0029] Such as Figure 1 to Figure 6 Shown; A negative pressure filter includes a filter tube 1, a filter device 2 and a controller, the filter device 2 is arranged in the filter tube 1, and one end of the filter tube 1 is provided with a pressure measuring sealing mechanism 4, so The other end of the filter tube 1 is provided with an oil cylinder, and the power end of the oil cylinder presses the filter device 2 on the working side of the pressure measuring and sealing mechanism 4; One side of the filter pipe 1 of the pipe 11 is provided with an anti-blocking sewage discharge mechanism 3, the liquid inlet pipe 12 is connected to the anti-blockage sewage discharge mechanism 3, a vacuum water tank is connected to the liquid discharge pipe 11, and the vacuum water tank is provided with Vacuum pump, drain port and pressure gauge, the anti-blocking and sewage discharge mechanism 3 communicates with the filter pipe 1 and cooperates with the filter device 2, the controller electric ...

Embodiment 2

[0032] On the basis of Embodiment 1, the pressure measuring and sealing mechanism 4 includes a sealing door 41, and at least one pressure sensor 42 is arranged on the sealing door 41, and a buffer block 43 is arranged on the pressure sensor 42. The sealing door 41 is provided with a sealing gasket 44; the pressure sensor 42 is electrically connected to the controller; one side of the filter barrel 21 is provided with a filtered liquid door 22, and the filtered liquid door 22 is provided with a concave return cavity 27, the liquid outlet hole 28 is set on the concave return cavity 27; the filter barrel 21 is provided with an inner arc-shaped sliding wall 23 on one side, the transition hole 24 is set in the inner arc-shaped sliding wall 23, and the filter One side of the tube 1 is provided with an outer arc-shaped sliding wall 13 that cooperates with the inner arc-shaped sliding wall 23; the filter bucket 21 is provided with at least two sealing strips, and the sealing strips are...

Embodiment 3

[0035] On the basis of Example 2, the gap between the filter tube 1 and the filter bucket 21 is 0.5mm to 2.0mm, and the thickness of the sealing ring 29 is 10mm to 20mm; the sealing ring 29 is made of silica gel, and the silica gel The hardness is 20 degrees to 50 degrees; the screw 32 revolving blade located on one side of the transition hole 24 is provided with a slow pressure cleaning notch 34; the ratio of the width of the screw 32 revolving blade to the width of the slow pressure cleaning notch 34 1: 0.3 to 0.7.

[0036] By setting the gap between the filter tube 1 and the filter bucket 21 to 0.5mm to 2.0mm, the phenomenon of difficulty in installation can be avoided. If the gap is too large, the filter will also flow directly to the liquid outlet pipe 11; It is set to 10mm to 20mm, and the hardness is set to 20 degrees to 50 degrees, so that after the sealing ring 29 is under pressure, one side thereof will be squeezed and deformed so that the side surface contacts the i...

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...
