Description

Single tube dry ice blasting machine

technical field

The utility model relates to a dry ice cleaning device, in particular to a single-tube dry ice cleaning machine.

Background technique

Mechanical equipment, electrical appliances, instruments, buildings, etc. in all walks of life are polluted all the time. Such as: corrosive substances left over from circuit board welding, steam turbine scaling, paint bursting, etc. These contaminations are unavoidable, so cleaning contaminated surfaces is an important task. In the past, the cleaning of the contaminated surface of components mainly used manual cleaning, sandblasting, high-pressure water cleaning and chemical cleaning. And other issues.

With the development of society, it has become a trend to use dry ice particles to clean the dirt on the surface of objects. When dry ice particles are used for cleaning, solid carbon dioxide particles hit the surface of the object during the spraying process. Since the particles are in an extremely low temperature state, they are not compatible with the workpiece. The temperature difference on the surface is extremely large, forming a "thermal shock". The solid carbon dioxide particles reach the bottom layer of the dirt under the action of high-speed flow energy and thermal shock energy. A "micro-explosion" is formed to separate the dirt from the workpiece to achieve the purpose of cleaning. The structure of the existing dry ice blasting machine is shown in Figure 1. The dry ice particles enter the receiving plate 16 horizontally arranged on the mounting plate 17 from the dry ice inlet 11, and then enter the ice hole 21 from the dry ice inlet backing plate on the receiving plate 16. Enter the dry ice steering wheel 18 in the mounting plate 17 and the dry ice delivery pit 81. The dry ice steering wheel 18 rotates under the drive of the motor, and the dry ice particles in the dry ice delivery pit 81 are sprayed on the surface of the object through the dry ice outlet hole 19 through the dry ice outlet 14 and then through the dry ice outlet hole 15 to clean the dirt. Although the dry ice blasting machine of this structure can clean the dirt on the surface of the object. But when working for a long time, because of not stopping blowing with the blowing hole 13, the gas is easy to solidify at low temperature, and wastes resources. After a period of time, the dry ice steering wheel 18 will be severely worn due to the solidification of the gas, and cannot be used normally.

The outlet backing plate and the ice outlet are sprayed onto the surface of the object to be cleaned to clean the dirt on the surface. It has the advantages that the gas is not easy to solidify, the cleaning effect is good, the workpiece is not polluted, and the workpiece is not easy to wear.

As an optimization, the ice inlet of the dry ice inlet plate, the ice inlet hole of the dry ice inlet backing plate, and the ice inlet hole of the dry ice inlet pressure plate are downwards corresponding to the side of the air inlet hole of the dry ice outlet pressure plate and the air inlet hole of the dry ice outlet backing plate of the dry ice delivery shaft. With such a design, the distance between the dry ice inlet and the air inlet hole at this angle is the shortest, and it is most convenient to fully mix with the air inlet.

As an optimization, a bearing and a sealing ring are installed between the dry ice delivery room where the dry ice delivery shaft is installed and the dry ice delivery shaft. Such a design can ensure sealing and reduce frictional resistance.

As an optimization, one side of the dry ice outlet plate has an air inlet of the dry ice outlet plate connected to the air inlet hole of the dry ice outlet backing plate, and the dry ice outlet connected to the outlet hole of the dry ice outlet backing plate is located on the other side of the dry ice outlet plate. Designed in this way, it is convenient to design, manufacture and use.

As an optimization, both the dry ice inlet plate and the dry ice outlet plate are equipped with a dry ice outlet backing plate and a compression spring for the dry ice inlet backing plate. Such a design can not only ensure compression, but also have spring cushioning properties.

After adopting the above-mentioned technical scheme, compared with the existing dry ice cleaning machine, the single-tube dry ice cleaning machine of the utility model has the advantages that the gas is not easy to solidify, the cleaning effect is good, the workpiece is not polluted, the workpiece is not easy to wear, the structure is reasonable, the processing is simple, the cleaning effect is good, and the work It has the advantages of high efficacy and wide promotion and use.
