Abstract

The utility model belongs to a cleaning device of the pipelines of equipment, which is provided with gas-liquid bidirectional cleaning function. The device is composed of a water pump and a water pump valve arranged above the cleaning liquid groove, and the upper side of the valve is provided with an air pump and an air valve. Two or more than two nozzles with valves are arranged on the upper water pipe of a reversing valve group. The device can clean the pipelines with a plurality of methods, such as adopting high pressure gas, cleaning liquid or the mixed liquor of the high pressure gas and the cleaning liquid, etc. Compared with the prior art, the device has the advantages of favorable cleaning effect, reasonable structure, wide range of application, high cleaning speed, etc.

Description

The two-way cleaning device of gas-liquid

The utility model device belongs to the cleaning field of equipment pipe.Be specially adapted to the cleaning device of metallurgical furnace cooling system, boiler and liquid chemical mass transfer pipeline etc.

In daily production and use, some equipment needs regular maintenance and maintenance, water cooling system as metallurgical furnace, the transmission pipeline of industrial, civilian boiler and liquid chemical material etc., operation through one period, owing to be transmitted the effect of thing, have dirt at inner-walls of duct, seriously influence equipment and normal the use.Clean in the said equipment method existing, generally all adopt artificial the cleaning, promptly operating personnel pour into cleaning fluid in the pipeline that is cleaned thing, because cleaning fluid is slow with the dirt reaction decomposes, so this method time-consuming bothersome and cleaning performance difference etc.Adopt the device of water pump in addition in addition with the cleaning fluid flow in pipes, though this cleaning device saves time than manual cleaning and cleaning performance slightly improves, but this device can only unidirectionally clean, because contained dirt was more when cleaning fluid flowed in cleaning, therefore often there is dirt that pipe blow-through is stopped up, cleaning can't be carried out.So this cleaning device can only carry out frequent cleaning to specific cleaning object, because of the scope of application is little bigger with the cleaning fluid waste, Gu in this field, use this cleaning device still not ideal enough.

The purpose of this utility model is that proposition is a kind of simple and reasonable, is easy to make and maintenance, and fast, the effective and economic two-way cleaning device of gas, liquid of cleaning reaction.

According to the purpose of this utility model, the cleaning device that we proposed is that gas, liquid alternately or simultaneously use, and cleaning device that can two-way cleaning.This cleaning device is to before being cleaned thing and cleaning, can adopt high pressure gas to carry out airflow scouring, and then carry out liquid and clean, for accelerating the reaction speed of cleaning fluid being cleaned conduit, the gas that can add high pressure again after injecting cleaning fluid increases the manifold pressure that is cleaned thing.After cleaning again with clear water to cleaning in the pipeline, adopt high pressure gas to blow off at last to be cleaned the residual liquid in the conduit again, be corroded in the pipe preventing.When dirt is too many in being cleaned conduit, adopting air scour still is that the liquid cleaning all might make line clogging, when being stopped up by dirt in the pipeline, can be by this device valve tuning, the air-flow that is cleaned in the conduit or liquid are oppositely washed away dirt or clean.So not only solve the obstruction of dirt in the pipeline, and can accelerate cleaning speed.Especially carry out forward and reverse flush clean repeatedly in the conduit to being cleaned, better effects if, and also cleaning is thoroughly clean.Because the two-way cleaning device of the utility model gas-liquid has These characteristics, so the composition of this cleaning device that we proposed can be described in detail with reference to the accompanying drawings.This accompanying drawing is the structural representation of the two-way cleaning device of gas-liquid.1 is band valve spout (A includes A1, A2, A3, A4......) for being cleaned thing, A in the accompanying drawings, F be the valve valve (F include F1, F2, F3, F4 ...), 2 is the water source, 3 is air pump, 4 is water pump.Be described in detail as followsly now with reference to the accompanying drawings, the said in this manual thing 1 of being cleaned is metallurgical vacuum drying oven, intermediate frequency, Efco-Northrup furnace or civilian, Industrial Boiler etc.Draw at each mouth of a river that at first will be cleaned thing 1, and link with the band valve spout A of this cleaning device.This gas, the two-way cleaning device of liquid are by tank, valve F, parts such as water pump 4 air pumps 3 and band valve spout A are formed, it is characterized in that above tank, being equipped with water pump 4, be connected to water pump valve F7, be connected with pressure regulating valve F8 in the upper end of water pump valve F7 in water pump 4 upper ends; Air pump 3 and air pump F6, and cleaning water pipe G and valve F5, the composition of change-over valve group is also to be connected to water supply valve door F1 and F3 respectively in the upper end of water pump valve F7, upper end at return pipe also is connected to backwater valve F2, F4 respectively, at the upper end water pipe of valve F1, F2 and valve F3, F4 two or more band valve spout A is housed.The operation principle of the utility model gas, the two-way cleaning device of liquid and process can be described with reference to the accompanying drawings.This accompanying drawing the thing 1 that is cleaned that goes out of example be two pipelines.If be cleaned thing 1 many pipelines are arranged, can on the upper end water pipe of valve F1, F2 and valve F3, F4, be connected to the band valve spout A of equal number.The course of work of this device is, the pipe to be treated that at first will be cleaned thing 1 connects and Open valve with band valve spout A, valve-off F2, F3, F5, F7, F8, booster air pump and Open valve F6, F1, F4, the flow direction of high pressure gas is to be entered by band valve spout A1, A2 by valve F2, emit, and emit by return pipe again by band valve nozzle A3, A4 through valve F4.Because the winding-up of high pressure gas, can dirt blows out in thing 1 interior conduit with being cleaned, when if dirty patch is than big and the moon plug pipeline in the pipeline, valve F1F4 can be closed, while Open valve F2, F3, air-flow then enters pipeline by valve F3 by band valve nozzle A3, A4, is emitted, and is emitted by return pipe through valve F2 again by band valve nozzle A1, A2.Adopt the cleaning fluid pipe blow-through to clean similar to above-mentioned high pressure gas winding-up, at first close air pump 3 and valve F6F5, open water pump 4 and valve F7, cleaning fluid then enters by above-mentioned passage and is cleaned thing 1 pipeline, and cleaning fluid is returned by return pipe and cleans in the liquid bath after pipeline has been cleaned.In order to quicken and to improve cleaning performance, can open air pump 3 and valve F6, the pressure of pipeline cleaning liquid inside is improved, flow velocity is accelerated, and can shorten scavenging period like this and improve cleaning performance.After cleaning up, thing 1 should switch off the pump 4 and valve F7 when being cleaned, the valve F5 that opens water source 2 washes all pipelines with clear water, make and do not have residual cleaning fluid in the pipeline, and then open air pump 3 and valve F6 behind the valve-off F5 again, blow off residue clear water in all pipelines with high pressure gas, close all valve F after thing is thoroughly cleaned out and be folded down all band valve nozzle A when being cleaned, so just finished whole cleaning processes.

The two-way cleaning device of the utility model gas-liquid has reasonable in design compared with prior art, and cleaning performance is good, and is applied widely and cleaning speed is fast, cleans in the pipeline of back and do not stay any residual liquid.This is extremely important to the service life that is cleaned thing.
