Dry ice cleaning machine capable of preventing dry ice particles from icing

Abstract

The invention discloses a dry ice cleaning machine capable of preventing dry ice particles from icing, and relates to the technical field of dry ice cleaning. The dry ice cleaning machine comprises a feeding hopper, a rack, a batching disc, a gun body connector and a high-pressure gas tank, wherein the feeding hopper is fixedly installed on the inner side of the upper end of the rack, the batching disc is fixedly installed on the portion, on one side below the feeding hopper, of the rack, a discharging pipe is integrally formed at the lower end of the feeding hopper, and the discharging pipe is fixedly connected with an ice inlet pipe on the batching disc through a movable clamping sleeve; and a stirring shaft is arranged in the feeding hopper in the vertical axis direction, a plurality of stirring blades are further arranged in the feeding hopper in the vertical direction at equal intervals, and one end of each stirring blade is fixedly connected to the stirring shaft. According to the dry ice cleaning machine, through the arrangement of the stirring blades, a first sealing ring, a second sealing ring, a third sealing ring, an ice outlet through groove, a three-way connecting piece and a first air conveying pipe and the cooperation of the components, dry ice can be effectively prevented from being frozen at all parts in the device when the device is used, and the use stability of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of dry ice cleaning, and in particular relates to a dry ice cleaning machine with anti-freezing of dry ice particles, which is mainly used for cleaning equipment through dry ice. Background technique [0002] Dry ice cleaning, also known as cold spraying, uses compressed air as the power and carrier, and dry ice particles as accelerated particles are sprayed onto the surface of the object to be cleaned through a special jet cleaning machine, using the momentum change and sublimation of solid dry ice particles moving at high speed. , melting and other energy conversion, so that the dirt, oil, residual impurities, etc. on the surface of the object to be cleaned are quickly frozen, so that they are condensed, embrittled, stripped, and removed with the air flow at the same time. Dry ice cleaning will not damage the surface of the object to be cleaned, especially the metal. It will not cause any damage to the sur...

Problems solved by technology

The dry ice cleaning machine provided by the present invention to prevent the accumulation of dry ice particles has a compact structure, which improves the problem of the accumulation of dry ice particles at the discharge port of the hopper, and improves the cleaning efficiency. For normal blanking, in order to solve the above technical problems, the technical means adopted in this publication is mainly to realize anti-icing by vibration, but although this technical means can play the role of anti-icing to a certain extent, the hopper is in the long-term During the vibration process of time, it will lead to the loosening of the material belt, the batching tray and the batching tray itself, resulting in insufficient air pressure inside the batching tray;

[0005] 2. Icing inside the batching tray. The function of the batching tray in the dry ice blasting machine is mainly to transfer and transport the dry ice. In order to ensure the normal delivery of dry ice, it is necessary to continuously blow air into the batching tray. Contains a certain amount of moisture. At this time, under the action of dry ice sublimation, the moisture in the air will condense in the ingredient tray when it is cold, which will cause the dry ice to freeze and bond inside the ingredient tray, affecting the normal ingredients;

[0006] 3. Icing in the connecting pipe of the gun body. The function of the connecting pipe of the gun body is to realize the connection between the batching tray and the spray gun, and to realize the delivery of dry ice to the spray gun. However, after the air enters the batching tray and brings out the dry ice, the air pressure will At the same time, the air also contains a certain amount of liquid water (water vapor liquefied in the ingredient tray). At this time, when it is transported in a narrow and rugged connecting pipe, the liquid water is easy to adhere to the inner wall of the connecting pipe and condense into ice. Affect the use of the connecting pipe (the liquid water loses kinetic energy or the kinetic energy is too small due to the collision between the liquid water and the inner wall of the pipe);
