Solid carbon dioxide cleaning machine

Abstract

The invention discloses a solid carbon dioxide cleaning machine. An ice mixing device of the solid carbon dioxide cleaning machine comprises a compressed air inlet pipe, an ice falling part, an ice falling rotating disc, a rotating mechanism, a Venturi assembly and an sprayed object outlet; an ice falling hopper is radially formed on the ice falling part; the ice falling rotating disc is mounted in the ice falling part and arranged on the outer side of the Venturi assembly in a sleeving mode; at least two ice falling holes corresponding to the ice falling hopper in position are radially formedin the ice falling rotating disc to form an ice falling channel and an adsorption cavity correspondingly; an air flow channel which can only allow an air flow to pass through is formed between the adsorption cavity and an inner channel of the Venturi assembly; and a mixture channel is further formed between the adsorption cavity and the tail end of a necking structure of the inner channel of theVenturi assembly. The adsorption cavity does not communicate with the atmosphere, and air in the Venturi assembly is supplemented so that smooth mixing of solid carbon dioxide particles and compressedair can be achieved, leakage of the compressed air is avoided, and an effective guarantee is provided for normal spraying of solid carbon dioxide. The solid carbon dioxide cleaning machine is furtherprovided with a purely-pneumatic-controlled ice cutting device.

Description

technical field [0001] The invention relates to a solid carbon dioxide cleaning machine. Background technique [0002] Particulate solid carbon dioxide cleaning technology is to mix compressed air with a certain pressure and solid carbon dioxide particles and spray them on the surface of the object to be cleaned. The impulse generated by the low temperature and high-speed movement of the solid carbon dioxide particles themselves makes the dirt crack, and the solid carbon dioxide particles quickly The volume expansion caused by sublimation makes the dirt peel off the surface of the object to be cleaned, so as to achieve the purpose of cleaning the surface of the object. Due to the excellent cleaning performance of particulate solid carbon dioxide, it is widely used in various cleaning occasions. [0003] Ice distribution is an important component of the solid carbon dioxide washing machine, which is used to complete the mixing of compressed air and solid carbon dioxide. The...

Problems solved by technology

[0004] For the axial ice distribution method, it is easy to leak air during operation, and the small solid carbon dioxide particles falling from the hopper will be blown away by the leaked compressed air, so that the small solid carbon dioxide particles cannot be mixed with the compressed air, which affects the operation of the equipment. run

In order to solve this problem, the only way to achieve the purpose of not being easy to mix is ​​to adjust the parameters of the compressor.

For this reason, multiple adjustments may be required under different working conditions, or the machine parameters must be adjusted before each start, which makes the operation of the machine more inconvenient

In addition, the cleaning medium generally includes cylindrical small particles of solid carbon dioxide and snowflake-shaped micro-particles of solid carbon dioxide. For snowflake-shaped solid carbon dioxide, the particles are small and easy to stick. It is not easy to solve the problem of unsmooth ice distribution due to condensation and icing

[0005] On the other hand, in order to make the solid carbon dioxide particles accumulated in the hopper fall smoothly, the cleaning machine whose raw material is solid carbon dioxide particles is usually equipped with an adjustable vibrator on the hopper. weight

And for the cleaning machine whose raw material is block solid carbon dioxide, owing to need to set up the ice cutting device that block solid carbon dioxide is cut into snowflake solid carbon dioxide, setting vibrator will influence the normal operation of ice cutting device, so it is difficult to solve the The problem that carbon dioxide particles do not fall smoothly
