Description

The pipeline decontamination apparatus

Technical field

The utility model relates to a kind of cold cycling wetting system, especially a kind of manpower, pipeline decontamination apparatus simple in structure saved.

Background technology

At present, when using existing dirt separator to clean the pipeline of cold cycling wetting system, the valve that will blind off a line earlier unloads scrubbing with the dirt-discharging hook of dirt separator, behind to be cleaned the finishing, the blowdown cover bolt is tightened again, and opens the path valve.This kind scrubbing mode, must close after the pressure release of path valve could scrubbing, influence pipeline to work normally, but also needs several staff's execute-in-places, the consumption manpower.In addition, need dismantle dirt-discharging hook when blowdown, take out filter screen and carry out scrubbing, the scrubbing time is approximately wanted 2-3 hour, and the time is longer.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of pipeline decontamination apparatus simple in structure, and the scrubbing automatically of this device is convenient to realize automation control, saves manpower, convenient management and do not influence the pipeline operate as normal when scrubbing.

In order to solve the problems of the technologies described above, the utility model comprises the scrubbing pipeline that is connected on the pipeline, the downward-sloping manifold of scrubbing pipeline middle part one side and the blow-off pipe that is connected with manifold of being connected, be provided with a cartridge filter for interception fluid impurity in the described manifold, be respectively equipped with one on the pipeline of described scrubbing pipe ends for the pressure transmitter of measuring corresponding pipe fluid pressure, described blow-off pipe is provided with a magnetic valve, and described magnetic valve is controlled the switching of magnetic valve by the pressure reduction of two described pressure transmitters by a controller.

Described manifold port place is sealed and installed with a dirt-discharging hook, and this dirt-discharging hook middle part arranges described blow-off pipe.

Described scrubbing inner-walls of duct middle part is formed with a cannelure.

The cannelure opening interior and this end that described cartridge filter both ends open, this cartridge filter one end are installed on the scrubbing inner-walls of duct arranges with the scrubbing pipeline axial is vertical, and the other end is pressed on the port of manifold by dirt-discharging hook.

Pipeline decontamination apparatus of the present utility model can be realized automatic control, can automatic pollution discharge, and do not need the field personnel to operate in person, saved manpower; And the process of having exempted the dismounting dirt-discharging hook, saved blowing time; And can blowdown when the pipeline operate as normal, for operation continuously provides assurance.

Description of drawings

Fig. 1 is the structural representation of the utility model pipeline decontamination apparatus;

Fig. 2 is the cross-sectional schematic of scrubbing pipeline and manifold in the utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Referring to Fig. 1 and Fig. 2, decontamination apparatus of the present utility model comprises scrubbing pipeline 1, manifold 4 and blow-off pipe 5, and described manifold 4 is connected with scrubbing pipeline 1, and described blow-off pipe 5 is connected with manifold 4.

Described scrubbing pipeline 1 middle part one side direction has a down dip and is connected with manifold 4, these manifold 4 inside are placed with a cartridge filter 6, these cartridge filter 6 one ends withstand on the cannelure of scrubbing pipeline 1 inwall, the other end places blow-off pipe 5 ports, by at blow-off pipe 5 ports dirt-discharging hook 10 being installed, cartridge filter 6 is fixed, described cartridge filter 6 both ends opens and wherein cartridge filter 6 withstand on the opening and the 1 axial vertical setting of scrubbing pipeline of cannelure one end, other end opening and manifold 4 axial vertical settings, the cartridge filter 6 of this spline structure can be with the interception of the impurity in the current and with its guiding manifold 4.

Described blow-off pipe 5 is arranged on the middle part of dirt-discharging hook 10 and is connected with manifold 4, on blow-off pipe 5, also be provided with a magnetic valve 8, this magnetic valve 8 is opened and closed by controller 9 controls, when magnetic valve 8 is opened, flow through the current part of scrubbing pipeline 1 in pipeline flows into the circulatory system, and another part flows to blow-off pipe 5 through manifold 4 and drains into the gutter, and the impurity dirts that wherein are deposited in the manifold 4 just can be discharged with current, when magnetic valve 8 cut out, current only can flow in the circulatory system by pipeline.

Described scrubbing pipeline 1 two ends are sealed and installed with inlet channel 2 and outlet conduit 3 respectively by ring flange, be respectively equipped with 7, two described pressure transmitters 7 of a pressure transmitter on described water-in and water-out

pipeline

2,3 outer walls hydraulic pressure in the water-in and water-out

pipeline

2,3 that records is changed into electrical signal transfer to controller 9 and via its processing.

When the impurity accumulation of mud is on cartridge filter 6, can make the pressure difference of scrubbing pipeline 1 water inlet end and water side become big.Before the work, in controller 9, set a certain pressure (as 0.05MPa) earlier.During work, controller 9 is gathered the force value of scrubbing pipeline 1 water inlet end and water side by pressure transmitter 7, calculate the pressure difference at scrubbing pipeline 1 two ends, when the actual pressure differential value at scrubbing pipeline 1 two ends reaches setting value, controller 9 provides magnetic valve 8 start signal, this moment, magnetic valve 8 was opened, the sluicing blowdown, scrubbing pipeline 1 two ends pressure reduction reduces gradually, when the actual pressure differential value at scrubbing pipeline 1 two ends dropped to less than setting value, controller 9 was given magnetic valve 8 shutdown signals, and magnetic valve 8 cuts out, stop blowdown, such structure has realized the function of automatic scrubbing.

Medium in above-described embodiment in the pipeline is example with water, and the utility model also is applicable to other fluid media (medium)s.

In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but these embodiment are included within the scope of the present utility model.
