Dry ice cleaning machine

Abstract

The invention discloses a dry ice cleaning machine. The dry ice cleaning machine comprises a cabinet, handrails, a touch screen, pulleys, climbing wheels, a buckle cover, a pressure adjusting valve switch, a pressure gauge, a signal wire interface, an ice outlet, a spray gun handle, a nozzle, a spraying pipe, an ice breaking machine, a supporting frame, an air inlet, a mixing chamber shell, a pressure adjusting valve, a pressure sensor, a main valve, a three-end pipe, a spray gun switch, a signal line, a single-chip microcomputer and an ice storage chamber. The dry ice cleaning machine is small and portable and can climbing slope, an ice blade is driven by a motor, dry ice in an ice storage tank is cut into broken particles, the touch screen is used for enabling the single-chip microcomputer to control the rotating speed of the motor according to different requirements, and therefore the ice discharging amount of the cleaning machine is controlled; for preventing the nozzle from beingblocked by freezing after long-time use, the spray gun is provided with a heating sleeve for heating the nozzle and melting ice slag in the nozzle in a short time, so that the dry ice cleaning machinecan be rapidly recovered and used; and the dry ice cleaning machine has the characteristics of being low in cost, simple to use, safe and efficient.

Description

technical field [0001] The invention relates to a dry ice cleaning machine, which belongs to the field of cleaning equipment. Background technique [0002] Dry ice blasting machine is a kind of washing machine, and the dry ice blasting method has been developed rapidly all over the world. The cleaning system sprays the dry ice particles from the dry ice blaster to the working surface to be cleaned through high-pressure air, and uses the physical reflection of temperature difference to make different substances separate at different shrinkage speeds. When the dry ice particles at -78 degrees Celsius touch the surface of the dirt, it will produce an embrittlement explosion phenomenon, so that the dirt will shrink and loosen, and then the dry ice particles will instantly gasify and expand 800 times. The strong peeling force of the product will quickly remove the dirt. Thoroughly peel off from the surface of the object, so as to achieve fast, efficient, safe and energy-saving c...

Problems solved by technology

[0003] The existing dry ice blasting machine has a large volume and does not change its movement. It needs to crush the dry ice into granules and put it into the cleaning machine, and it is impossible to control the amount of dry ice used, resulting in waste. The dry ice nozzle is easy to frost and freeze under long-term work. , causing blockage, it takes tens of minutes to melt, reducing the working efficiency of the cleaning machine
