Description

A kind of cooler is at the road cleaning device

Technical field

The utility model relates to cleaning device, and the cooler that specifically relates to screw-rod air compressor is at the road cleaning device.

Background technology

At present, the cooling system of many equipment is to adopt recirculated water cooling mode, owing to contain Ca in the cooling water ²⁺, Mg ²⁺Deng impurity, circulating water pool is subjected to the influence of surrounding environment in addition, and equipment is after using a period of time, can produce fouling, the obstruction of mud dirt in its cooler cooling water pipe, cause cooling effect to descend, the equipment running temperature is higher, thereby makes that the equipment operating efficiency descends, energy consumption rises.Screw-rod air compressor for example, because of after above-mentioned reason causes the compressor operation temperature drift, used senior cooling fluid (screw-rod air compressor special oil), oil are can to reduce significantly the service life of auxiliary materials such as separator, oil strainer, auxiliary equipment, and cause oil piping system coking, head to damage easily, cause high maintenance cost.

For making screw-rod air compressor can efficiently operation, must regularly clean cooler.Traditional cleaning way is: 1, pull down cooler; 2, with steel wire the cooling tube of cooler is manually dredged; 3, with the scale forming matter in the diluted acid soaking and washing cooler tube, to the true qualities of forthright copper; 4, rinse out the diluted acid residue with clear water; Cooler is reinstalled body, finish cleaning.This conventional clean mode exists following problem: 1, because this body structure of screw-rod air compressor is compact, the space is little, dismounting oil cooler, aftercooler is very inconvenient, each cleaning all will be with 5～6 people, about two day time was finished this work, and the dismounting oil cooler will be poured out the senior cooling fluid of meeting loss 20～30L with being worth expensive senior cooling fluid in the cooler; 2, the cooler of screw-rod air compressor is to be 8mm by up to a hundred internal diameters, and wall thickness is that the copper tube of 3mm is formed, and with steel wire every copper tube is disclosed wearing, and dredges every pipeline, easily copper tube is caused hard defects; And the corrosivity of diluted acid is bigger, can make the attenuation of copper tube wall thickness, produces as cooler and leaks, and not only can pollute the complete machine cooling fluid, when serious head is scrapped, and causes the substantial equipment accident; 3, dismounting is all wanted in each cleaning, damages the related components of cooler and air compressor machine easily.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of cooler at the road cleaning device, it does not need the dismounting cooler just can clean automatically, not only can avoid the related components of scratch cooling water pipe, damage cooler and equipment, and scavenging period is short, working strength of workers is low.

The technical solution of the utility model is as follows: a kind of cooler is at the road cleaning device, comprise the cleaning agent groove, be inserted with feed tube and drain pipe in this cleaning agent groove, described feed tube joins with the outlet pipe of cooler behind the pump and first block valve, and the water inlet pipe that described drain pipe is connected to described cooler takes back described cleaning agent groove behind second block valve; The outlet pipe of described cooler connects described feed tube again behind the 3rd block valve, the water inlet pipe of described cooler connects described drain pipe again behind the 4th block valve.

For preventing the corrosion of cleaning agent to valve, as to further improvement in the technical proposal, described block valve is stainless steel.

As further improvement, described pump is portable circulating pump, and volume is less.

For the required cleaning agent of energy splendid attire cooler complete alternation, to satisfy cleaning requirement, the volume of described cleaning agent groove is 300～400L.

The utility model is used to carry the feed tube and the drain pipe of cleaning agent, one end all is inserted in the cleaning agent groove, the other end is connected on the outlet pipe and water inlet pipe of cooler, cleaning agent groove, feed tube, pump, cooler, drain pipe and block valve have been formed an enclosed cleaning agent circulatory system, it is power source with the pump, with certain density cleaning agent is circulating carrier, produce pressure and cleaning agent corrosiveness when turning round, wash impurity and incrustation scale in the cooler water pipe incrustation scale in the cooler water pipe by pump.During cleaning, close the 3rd block valve and the 4th block valve, thereby disconnect the cooling water pipeline that leads to cooler, open first block valve and second block valve, cleaning agent flows into the cooler outlet pipe by feed tube through pump, and cleaning agent enters that the cooler cooling water pipe circulates, pipe blow-through, is flowed out after drain pipe flows back to the cleaning agent groove by the cooler water inlet pipe, circulation cleans up until the cooling water pipe with cooler so repeatedly; After cleaning end, close first block valve and second block valve, thereby disconnect detergent line, open the 3rd block valve and the 4th block valve, cooling water enters cooler circulation, equipment operate as normal.

Owing to adopted technique scheme, the beneficial effects of the utility model are:

1, do not need the dismounting cooler, just can clean, alleviated labour intensity, avoided damaging the related components of cooler and equipment yet;

2, remove impurity and incrustation scale in the cooler water pipe by the fluid pressure of cleaning agent circulation and corrosivity, can the scratch water pipe, and the cleaning efficiency height, traditional cleaning method generally needed just can finish in two days, adopted this cleaning device just can finish cleaning task in one day at the most;

Need not dismantle cooler during 3, owing to cleaning, just need not bleed off the lubricating oil of cooler the inside, avoid the waste of lubricating oil in the cooler, nor polluted the environment.
