Abstract

The utility model discloses a dirt removing and cleaning device for the interior of a pipeline, which comprises an elastic expansion pipe, a flexible liquid injecting pipe, and flexible drain pipes. The elastic expansion pipe is sheathed on the flexible liquid injecting pipe, both ends of the elastic expansion pipe are provided with gas sealing clamps, roller balls are embedded in the gas sealing clamps, and an air valve core is arranged between the two gas sealing clamps. An inner cavity of the liquid injecting pipe is provided with the drain pipes which are not communicated with each other, after one end of the drain pipes extends out from a pipe wall of the liquid injecting pipe, a valve is arranged on one end of the drain pipes, and one end of the liquid injecting pipe is provided with a valve. Dirt is removed by chemical cleaning liquid, and the utility model has the advantage of good effect on removing dirt.

Description

The eliminating sludge in pipe cleaning device

The utility model relates to the eliminating sludge in pipe cleaning device of a kind of heat exchanger swan-neck and straight tube.

The present eliminating sludge in pipe cleaning device that uses, its operation principle all are utilization theory of mechanics cutting incrustation scales, and its cleaning performance is not ideal enough.

The purpose of this utility model provides a kind of apparatus for eliminating sludge in pipe, utilizes this device can pass through the cleaning fluid scale removal, quick, safety, efficient.

The purpose of this utility model is to realize like this.This device comprises elastic expansion pipe, flexible liquid injection pipe, flexible discharging tube, the elastic expansion pipe box is contained on the flexible liquid injection pipe, be provided with envelope gas card at elastic expansion pipe two ends, envelope gas card is embedded in ball, between two envelope gas cards valve inside is arranged, the mutual not discharging tube of UNICOM of liquid injection pipe inner chamber, discharging tube one end is provided with valve after the fluid injection tube wall stretches out, and liquid injection pipe one end is provided with valve.At the liquid injection pipe other end plug is arranged, there is the leakage fluid dram that passes the elastic expansion tube wall in the liquid injection pipe stage casing, and plug is arranged on the leakage fluid dram.

The utility model is owing to use the chemical cleaning solution scale removal, avoided the machine cut incrustation scale can not damage the shortcoming of tube wall, descale effect safety, efficient crooked, easily.

Below in conjunction with accompanying drawing in detail an embodiment of the present utility model is described in detail.

Fig. 1 is a cross-sectional schematic of the present utility model

Fig. 2 is that the A-A of Fig. 1 is to cut-away view

The utility model eliminating sludge in pipe cleaning device comprises elastic expansion pipe (2), flexible liquid injection pipe (8), flexible discharging tube (3), elastic expansion pipe (2) is sleeved on the flexible liquid injection pipe (8), be provided with envelope gas card (10) at elastic expansion pipe (2) two ends, envelope gas card (10) is embedded in ball (5), between two envelope gas cards (10) valve inside (4) is arranged, the mutual not discharging tube of UNICOM (3) is arranged in the liquid injection pipe (8), discharging tube (3) one ends are provided with valve (6) after liquid injection pipe (8) wall stretches out, liquid injection pipe (8) one ends are provided with valve (7).Another has plug (1) at liquid injection pipe (8), and there is the leakage fluid dram (9) that passes elastic expansion pipe (2) wall in liquid injection pipe (8) stage casing, and plug (11) is arranged on the leakage fluid dram (9), by the chemical cleaning solution scale removal, and its features high scale-removing effect.In need clean straight pipeline during incrustation scale, build plug (11), take off plug (1), flexible liquid injection pipe (3) is slowly delivered to the pipeline depths along being cleaned tube wall by ball (5), when flexible liquid injection pipe (8) when being obstructed, show that pipe to be treated is blocked herein, available inflator is inflated pressurization by valve inside (4), elastic expansion pipe (2) is expanded, be close to and be cleaned tube wall and watch a period of time quietly, after seeing that elastic expansion pipe (2) is air tight, get another eliminating sludge in pipe cleaning device, build plug (11), take off plug (1), send into then to be cleaned and manage in the other end, when flexible liquid injection pipe (8) is obstructed, inflate pressurization with inflator by valve inside, elastic expansion pipe (2) is expanded, be close to and be cleaned tube wall, be sure of air tight after, valve-off (6) is opened valve (7), injects cleaning fluid by flexible liquid injection pipe (8) in being cleaned pipe, after after a while, cleaning fluid and incrustation scale reaction produce gas, form air pressure, and be full of airtight being cleaned in the pipe, open valve (6) immediately, allow cleaning fluid discharge circulation, scavenging period can be by discharging cleaning fluid and injecting cleaning fluid F ³⁺ _e, F ²⁺ _eIon concentration judges whether incrustation scale is removed, and whether corrodes tube wall, behind the removing incrustation scale, and can be by injecting neutralizer, passivating solution, the protection tube wall.In need mediations intersects arm during incrustation scale; earlier behind the mediation straight tube; build plug (1); cancellation plug (11); flexible liquid injection pipe (8) is sent in the straight pipe; allow leakage fluid dram (9) aim at intersect arm one port, in the elastic expansion pipe, inflate punching press, make elastic expansion pipe (2) be close to branch pipe wall; a discharge opeing (9) and a mouth of pipe communicate; whether to aim at a mouth of pipe, can in liquid injection pipe, (8) add water in order verifying, to see whether water discharges from a mouth of pipe other end; can stop after the draining to liquid injection pipe (8) water filling; send into the flexible discharging tube (8) of another eliminating sludge in pipe cleaning device from the mouth of pipe other end, elastic expansion pipe (2) is expanded, be close to and be cleaned tube wall; cleaning fluid and discharge cleaning fluid reinject; incrustation scale is thoroughly removed in the circulation of realization cleaning fluid, and neutralizer or passivating solution recycling-guard tube wall reinject.
