Description

Technical Field

[0001] The utility model relates to the technical field of dry ice cleaning machines, and more specifically, to a semi-automatic dry ice cleaning machine. Background Art

[0002] In a dry ice cleaning machine, the cleaning system sprays dry ice pellets of the dry ice cleaning machine onto the working surface to be cleaned through high-pressure air. By using the physical reaction of temperature difference, different substances are separated at different shrinkage rates. When the -78°C dry ice pellets come into contact with the dirt surface, embrittlement and explosion will occur, so that the dirt shrinks and loosens. Then the dry ice pellets will instantly vaporize and expand 800 times, generating a strong peeling force to quickly and thoroughly peel off the dirt from the object surface, thus achieving a fast, efficient, safe and energy-saving cleaning effect.

[0003] For the existing dry ice cleaning machine, it is necessary to pour the dry ice cut into pellets into the dry ice cleaning machine and spray it onto the equipment to be cleaned through the gun head by a pressure device. When the cut dry ice pellets are poured into the dry ice cleaning machine together, they are easy to condense, affecting the subsequent cleaning effect. Therefore, the utility model provides a semi-automatic dry ice cleaning machine. Summary of the Invention

[0004] In order to make up for the above deficiencies, the utility model provides a semi-automatic dry ice cleaning machine, aiming to improve the problem that for the existing dry ice cleaning machine, it is necessary to pour the dry ice cut into pellets into the dry ice cleaning machine and spray it onto the equipment to be cleaned through the gun head by a pressure device, and when the cut dry ice pellets are poured into the dry ice cleaning machine together, they are easy to condense, affecting the subsequent cleaning effect.

[0033] Embodiment

[0034] Such as Figures 1-4As shown in the figure, the present utility model provides a semi-automatic dry ice cleaning machine, including: a device box body 1, a limiting groove 2, a crushing mechanism 3, an air compressor 4, a collection box 5, a pressure pipe 6, and a gun head 7. The device box body 1 is of a cavity structure. A filter screen plate 100 is horizontally arranged in the device box body 1. The filter screen plate 100 divides the cavity structure into an upper part space 110 and a lower part space 120. The limiting groove 2 penetrates up and down. The limiting groove 2 is arranged on the upper surface of the filter screen plate 100. The crushing mechanism 3 is rotatably restricted in the limiting groove 2. The air compressor 4 is arranged in the lower part space 120. The collection box 5 is arranged below the filter screen plate 100. The top of the collection box 5 is provided with an inlet. The air compressor 4 is connected to one side of the collection box 5. One end of the pressure pipe 6 is connected to the collection box 5, and the other end penetrates the device box body 1 and is externally connected to the gun head 7. The pressure pipe 6 is arranged on the opposite side of the air compressor 4. By adding dry ice blocks or dry ice particles into the limiting groove 2, the dry ice is crushed or re-crushed by the crushing mechanism 3 and then enters the collection box 5 in the lower part space 120 through the filtration of the filter screen plate 100. The air compressor 4 sends pressurized air into the collection box 5. The air drives the dry ice particles to enter the pressure pipe 6 at a high speed, forming an ice knife at the position of the gun head 7. The operator cleans the device to be cleaned by holding the gun head 7.

[0035] It should be noted that the air compressor 4 is connected to one side of the collection box 5 near the lower end. Preferably, the connection position of the pressure pipe 6 and the air compressor 4 is set at the same height. In order to prevent the dry ice from being affected by the external temperature of the device box body 1, preferably, the side wall of the device box body 1 is a double-layer heat preservation mechanism. At the same time, cooling pipes can be laid in the device box body 1. The cooling pipes are externally connected to a control system, so as to ensure that the temperature in the device box body 1 is relatively low and prevent the dry ice from melting in the device box body 1.

[0036] In this embodiment, a collection funnel 8 is further included. The upper edge of the collection funnel 8 is arranged below the filter screen plate 100. The lower part of the collection funnel 8 is connected to the top inlet of the collection box 5. The collection funnel 8 can guide the dry ice falling from the filter screen plate 100 into the collection box 5.

[0037] It should be noted that the structure of the collection box 5 is as Figure 4 shown. The dry ice particles collected by the collection funnel 8 enter through the inlet on the collection box 5. The inlet is inclined towards the direction of the pressure pipe 6, so as to avoid the high-pressure air generated by the air compressor 4 from entering the collection box 5 and mostly flowing out from the inlet. One end of the collection box 5 connected to the pressure pipe is provided with an enlarged section.

[0038] In this embodiment, the limiting groove 2 is of an annular structure, and an opening 200 is formed on one side of the limiting groove 2. The crushing mechanism 3 includes: a rotating motor 300, a rotating shaft 310, and stirring rods 320. The rotating motor 300 is arranged above the limiting groove 2. One end of the rotating shaft 310 is fixed on the output shaft of the rotating motor 300, and the rotating shaft 310 extends to the bottom of the limiting groove 2. Each stirring rod 320 is evenly and detachably arranged on the rotating shaft 310. The rotating motor 300 drives the stirring rods 320 to re-crush the dry ice to be crushed in the limiting groove 2. When the rotating motor 300 works, it will generate vibrations, and the vibrations are transmitted to the filter screen plate 100. The vibration of the filter screen plate 100 can vibrate the dry ice particles and drop them into the lower space 120.

[0039] In this embodiment, an air outlet 130 is arranged at the top of the device box body 1, a feed inlet 111 is arranged on one side of the upper space 110 of the device box body 1, the feed inlet 111 is close to the opening 200, an opening fan 121 is arranged on one side of the lower space 120 of the device box body 1, and the opening fan 121 is close to the air compressor 4. An operator can add dry ice to the opening 200 through the feed inlet 111, and at the same time, the lower space 120 can be detected through the opening fan 121.
