[0002] Dry ice cleaning machine is a kind of cleaning machine. Dry ice cleaning has been rapidly developed around the world. The cleaning system uses high-pressure air to spray dry ice particles from the dry ice cleaning machine onto the working surface that needs to be cleaned. The physical reaction of temperature difference is used to make different substances separate at different shrinkage speeds. When the dry ice particles at -78 degrees Celsius come into contact with the dirt surface, a brittle explosion phenomenon will occur, causing the dirt to shrink and loosen. Then the dry ice particles will instantly vaporize and expand 800 times, generating a strong peeling force, quickly and thoroughly removing the dirt from the surface of the object, thereby achieving a fast, efficient, safe and energy-saving cleaning effect.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5A dry ice cleaning machine hopper with heat preservation function includes a cleaning shell 1 and a composite hopper mechanism 3. The inner top wall of the cleaning shell 1 is provided with a placement groove 2. The composite hopper mechanism 3 includes an outer protective tube 301. The outer protective tube 301 should be made of wear-resistant and corrosion-resistant stainless steel plate. The inner wall of the outer protective tube 301 is fixedly connected with a middle heat-resistant tube 302. The middle heat-resistant tube 302 should be made of aluminum foil with high thermal resistance and good reflectivity. The inner wall of the middle heat-resistant tube 302 is fixedly connected with an inner insulation tube 303. The inner insulation tube 303 should be made of rubber sponge with low thermal conductivity and good insulation effect.

[0025] An ear plate 6 is arranged above the composite hopper mechanism 3, and the outer protective tube 301, the middle heat-resistant tube 302 and the inner heat-insulating tube 303 are all fixedly connected to the bottom surface of the ear plate 6, and the outer surface of the ear plate 6 is slidably connected to the inner wall of the placement groove 2. The placement groove 2 is used to limit the ear plate 6, and a discharge port 4 is arranged below the composite hopper mechanism 3, and the outer protective tube 301, the middle heat-resistant tube 302 and the inner heat-insulating tube 303 are all fixedly connected to the upper surface of the discharge port 4. The discharge port 4, the ear plate 6 and the composite hopper mechanism 3 are a whole when processed in the factory, and should be made into an integral finished product.

[0026] A valve 5 is installed inside the discharge port 4. By using the valve 5, the dry ice can be blocked to prevent it from spilling out.

[0027] An auxiliary cooling mechanism 9 is arranged on the left side of the compound hopper mechanism 3, and the auxiliary cooling mechanism 9 includes a surrounding tube 901 and a water-cooled radiator 902. The water-cooled radiator 902 is installed on the left side wall of the cleaning machine casing 1. The water-cooled radiator 902 is composed of a plurality of heat sinks and a fan. In the water-cooled radiator 902, water transfers heat to the air through the heat sink, and its own temperature is reduced. The surrounding tube 901 is sleeved on the outer surface of the compound hopper mechanism 3. The surrounding tube 901 should be bonded to the outer surface of the compound hopper mechanism 3 to prevent the surrounding tube 901 from falling off.

[0028] A suction pump 903 is installed on the outer surface of the water-cooled radiator 902. The input end of the suction pump 903 extends into the interior of the water-cooled radiator 902, so as to extract the cooling water inside the water-cooled radiator 902. The output end of the suction pump 903 is fixedly connected to a water supply pipe 904. The end of the water supply pipe 904 away from the suction pump 903 is connected to the surrounding pipe 901. The water outlet end of the surrounding pipe 901 is fixedly connected to a water inlet pipe 905. The water inlet pipe 905 penetrates the inner wall of the water-cooled radiator 902 and extends to the interior of the water-cooled radiator 902. Both the water inlet pipe 905 and the water supply pipe 904 are hoses, which can produce a certain deformation to avoid damage when the composite hopper mechanism 3 shakes.

[0029] A group of guide columns 7 are fixedly connected to the bottom surface of the ear plate 6, each guide column 7 passes through the inner bottom wall of the placement groove 2 and extends to the interior of the cleaning housing 1, and a spring 8 is wound around the outer surface of each guide column 7. The upper and lower ends of each spring 8 are respectively fixedly connected to the inner top wall of the cleaning housing 1 and the outer surface of the guide column 7. By using the cooperation between the guide column 7 and the spring 8, the ear plate 6 and the compound hopper mechanism 3 can be reset when they are shaken.

[0030] A knocking mechanism 11 is provided inside the cleaning casing 1, and the knocking mechanism 11 includes a motor 1101, and the motor 1101 is installed on the inner wall on the back of the cleaning casing 1, and the output end of the motor 1101 is fixedly connected to a rotating rod 1102, and the outer surface of the rotating rod 1102 is fixedly connected to a cam 1103, and the outer surface of the outer protective tube 301 is fixedly connected to an outer protruding plate 10. By starting the motor 1101, the rotating rod 1102 can be driven to rotate, and the cam 1103 can be driven to push up the outer protruding plate 10, so that the composite hopper mechanism 3 can be shaken, which is convenient for dry ice unloading.

[0031] The blocking mechanism 12 includes a positioning rod 1203, the bottom end of which is fixedly connected to the upper surface of the cleaning machine housing 1, the outer surface of the positioning rod 1203 is rotatably connected to a baffle 1202, and the upper surface of the baffle 1202 is fixedly connected to a handle 1201. By using the handle 1201, the baffle 1202 and the positioning rod 1203 in cooperation, the dry ice inside the composite hopper mechanism 3 can be shielded to prevent the dry ice from contacting with the air, thereby further reducing the probability of vaporization.

[0032] A dry ice cleaner 13 is installed on the inner bottom wall of the cleaning housing 1. By using the dry ice cleaner 13, dry ice can be used for cleaning, which is an existing mature technology.

[0033] Working principle: By using the handle 1201, the baffle 1202 can be rotated, and dry ice can be put into the composite hopper mechanism 3. Under the joint insulation effect of the outer protective tube 301, the middle heat-resistant tube 302 and the inner heat-insulating tube 303, the dry ice can be effectively prevented from vaporizing. By starting the suction pump 903, the condensed water inside the water-cooled radiator 902 can be extracted and sent to the inside of the surrounding tube 901 through the water supply pipe 904. The surrounding tube 901 can replace the heat. The condensed water at the heat replacement point inside the surrounding tube 901 can be discharged into the inside of the water-cooled radiator 902 again through the water inlet pipe 905, realizing the circulation cooling of the outer surface of the outer protective tube 301, thereby helping to prevent the dry ice from vaporizing. When it is necessary to discharge dry ice, first open the valve 5, and then start the motor 1101, which can drive the rotating rod 1102 and the cam 1103 to rotate, so that the cam 1103 can continuously lift the protruding plate 10, so that the protruding plate 10 can shake, so that the dry ice can be easily delivered into the dry ice cleaning device 13 for cleaning.
