Description

Ejecting device of dry ice cleaning machine

Technical Field

The utility model relates to a dry ice washs the field, specifically is a jetter of dry ice cleaning machine.

Background

The dry ice cleaning technology is characterized in that compressed air is used as power and a carrier, dry ice particles are sprayed to the surface of an object to be cleaned, and carbon deposit, bonded dirt and the like are quickly peeled and removed by utilizing impact force generated by high-speed movement of solid dry ice particles and combining low temperature of the dry ice and thermal expansion generated by sublimation. Because of the advantages of rapidness, colleges, safety, energy conservation, environmental protection and the like, the automobile maintenance tool is widely applied to automobile maintenance.

When an automobile engine is cleaned, the front end of a spray gun of a dry ice cleaning machine needs to be inserted into a cylinder of the engine, dry ice is sprayed into the cylinder, and during the process of spraying the dry ice, the dry ice splashes out of a socket of the spray gun, so that the dry ice is greatly wasted and lost. Secondly, the wide nozzle of dry ice washing that adopts at present all carries the dry ice granule through circular pipeline, when the pipeline cross-section is changed into the slender profile of nozzle by the circular, can lead to the dry ice granule to distribute inhomogeneous on the nozzle cross-section, leads to the nozzle effective width to hang down when wasing, has reduced cleaning efficiency.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a dry ice cleaning machine's jetter to solve the problem that proposes among the above-mentioned background art.

In order to solve the technical problem, the utility model discloses a technical scheme is:

a spraying device of a dry ice cleaning machine comprises a spray gun connected with a cleaning machine body, wherein the spray gun comprises a spray rod, a nozzle and a hose, the rear end of the spray rod is connected with one end of the hose through a quick connector, the other end of the hose is communicated with a discharge pipe arranged on the cleaning machine body, a spring is further sleeved on the periphery of the rod body of the spray rod, a movable cover plate and a fixed baffle plate which are respectively connected with the front end and the rear end of the spring are further concentrically arranged on the rod body of the spray rod, a telescopic sheath is wrapped on the periphery of the spring, two ends of the telescopic sheath are respectively connected with the movable cover plate and the fixed baffle plate, a limiting bulge used for limiting the movable cover plate to continuously move towards the front end of the spray rod is further arranged on the spray rod, the front end of the spray rod is connected with the nozzle, the nozzle is splayed, two guide plates which, the narrow edges at the two sides of the guide plate are respectively contacted and connected with the two splayed inner walls in the inner cavity of the nozzle.

Furthermore, the telescopic sheath is a stainless steel telescopic pipe.

Furthermore, a handle and a holding rod are further arranged on the spray rod.

Further, the movable cover plate is close to the front end of the spray rod, and the fixed blocking piece is close to the rear end of the spray rod.

The utility model has the advantages that:

the utility model provides a dry ice cleaning machine's jetter, its simple structure, novelty, two guide plates that are splayed symmetric distribution through being the inside setting of nozzle of splayed can make the dry ice granule more even in nozzle export distribution, and the abluent effective width of nozzle is bigger to further improvement the cleaning efficiency. When the engine needs to be cleaned, after the nozzle is inserted into a cylinder of the engine, the movable cover plate moves backwards along the rod body of the spray rod and compresses the spring, and the spring in the compressed state generates reaction force on the movable cover plate, so that the movable cover plate is blocked at an inlet inserted into the cylinder to prevent dry ice from splashing out.
