Problems solved by technology

[0004] The object of the invention of the present invention is to: aim at the above existing problems, to provide a pipeline filter, which can integrate the pipeline transportation function and the filtering function, and can realize the filtration of impurities in the pipeline. , still does not affect the flow of liquid in the pipeline, and at the same time, when the pressure in the pipeline is unbalanced, it can effectively relieve the pressure of the filter, avoiding damage to the filter in the case of a strong change in the pressure difference of the water flow, or causing filtration Impurities in the container re-enter the water under pressure

Embodiment 1

[0038] Such as figure 1 As shown, a pipeline filter 2 of the present invention discloses a pipeline filter 2, which includes a pipe body 1, and a separation plate 3 is arranged in the pipe body 1, and the separation plate 3 separates the pipe body 1 The channel is divided into a pressure relief channel and a filter channel, and a filter 2 is arranged on the filter channel. A valve body 4 is arranged on the pressure relief passage. The valve body 4 is used to control the flow of the pressure relief passage to ensure the effective filtration of the filter 2 , and the valve body 4 can also control and adjust the pressure difference on both sides of the filter 2 . The flow passer is sheet-shaped, and the filter 2 is obliquely arranged at the entrance of the filter channel, and the filter 2 and the axial direction of the pipeline form an included angle of 30-60 degrees. After the filter 2 is tilted, it plays the role of drainage to ensure that the pressure on the filter 2 is redu...

Embodiment 2

[0043] The intelligent control system of the pipeline filter includes a pipeline unit, a filter unit, a valve unit, a partition unit, a detection unit and a control unit;

[0044] The pipe unit includes a pipe body, an annular spoiler layer arranged on the inner wall of the pipe, and a reinforcement layer fixed on the outer wall of the pipe; the spoiler layer is composed of a plurality of spoiler rings, and the distance between adjacent spoiler rings is 2-3cm, the height of the spoiler ring protruding from the pipe body is 4-6mm; the pipe body is a polyethylene plastic pipe; the reinforcement layer is a ring-shaped structure made of carbon steel material, between the reinforcement layer and the pipe body There is a 0.2-0.5mm thick flax braid layer between them;

[0045] The partition unit includes an isolation plate and a position regulator, the regulator includes an adjustment frame, a screw, and a partition motor, the isolation plate is installed on the adjustment frame, the...

Embodiment 3

[0052] Based on embodiment 2 intelligent control system, its control method is:

[0053] Step 1: When the isolation plate is set at a certain position in the pipe body, the cross-sectional ratio of the pressure relief channel to the filter channel is (1-1.5): (1.5-1.8);

[0054] Step 2: Pass the water flow with a water pressure of 100-150kPa into the pipeline unit, and measure the water pressure at the inlet of the pipeline unit through the third pressure sensor;

[0055] Step 3: The controller controls the rotation of the valve motor to control the action of the valve unit, and measures the water pressure in the pressure relief channel through the first pressure sensor; measures the water pressure in the filter channel through the second sensor;

[0056] Step 4: The controller controls the valve motor so that the water pressure at the inlet of the pipeline unit: the water pressure in the filter channel is not greater than 1.35;

[0057] Step 5: When the valve motor is fully ...

Abstract

The invention relates to a pipeline filter, which is a filter built into a pipeline and belongs to the field of filters. channel, a filter is set on the filtering channel. This structure can effectively relieve the pressure of the filter, prevent the filter from being damaged due to excessive pressure, and affect the normal filtration of the filter. The design of the pressure relief channel can avoid damage to the filter when the pressure in the pipe is not balanced. , At the same time, this structure can ensure the smooth flow of the passage when the filter is blocked, and prevent the rupture of the pipe body caused by excessive pressure in the pipe body. A valve body is arranged on the pressure relief passage. The design of the valve body can control the flow of the pressure relief channel. The design of the valve body can prevent the filter from being filtered well and ensure the effective filterability of the filter. In addition, the valve body can effectively control and adjust both sides of the filter. pressure difference.

Description

technical field [0001] The invention relates to a pipeline filter, which is a filter built into a pipeline and belongs to the field of filters. Background technique [0002] The filter is an indispensable device on the conveying medium pipeline. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, constant water level valve, and other equipment of the square filter. The filter is composed of a cylinder, a stainless steel filter, a sewage discharge part, a transmission device and an electrical control part. After the water to be treated passes through the filter cartridge of the filter screen, its impurities are blocked. When cleaning is required, just take out the detachable filter cartridge and reinstall it after treatment. Therefore, the use and maintenance are extremely convenient. When the filter is working, the water to be filtered enters from the water inlet, flows through the filter screen, and enters the pipeline required b...
