Dry ice cleaning equipment

The present invention relates to a dry ice cleaning device, in particular to a method in which dry ice particles are directly dropped into a grinding device by a feeding hopper, and the dry ice particles are ground to a required thickness by a grinding device, and the setting is performed by an ice tray device. The dry ice is actually delivered to the spray gun, and is sprayed out by the spray gun for cleaning action. The overall volume is light and easy to move.

According to Dry Ice cleaning, it has been widely used in the cleaning of machines or instruments in various industries. The so-called dry ice cleaning is a kind of dry ice granules made of liquid carbon dioxide (CO ₂ ), with high-speed impact and thermal expansion. The method of shrinking the surface of cleaning objects, like the general sand blasting system, the dry ice particles are accelerated by compressed air. At present, most of the equipment can use the compressed air of the factory hollow press, and the principle of ultra-low temperature cooling of dry ice particles will be used for thermal expansion and contraction. The contaminants attached to the surface of the object are peeled off, so as not to damage the object, and at the same time, the dirt on the surface of the object is cleaned to maintain the quality of the product, and the dry ice particles are vaporized into carbon dioxide immediately after being in contact with the surface of the object to be cleaned. There is no residue on the object and the ground; and the conventional dry ice cleaning device, such as the announcement No. 345049, includes a cover at the top of a casing and communicates inwardly with a feed hopper, the bottom of which is located in the casing And connecting a feeding assembly, the feeding assembly is respectively connected with the transmission assembly and the control assembly, so that the bottom of the feeding assembly is two sides Do not connect with an air inlet pipe and an air outlet pipe, and connect a spray gun from the air outlet pipe, and a vibration motor on the outer side wall of the feed hopper, so that the dry ice particles can fall into the feed assembly through the feed hopper and utilize The transmission assembly is transmitted to the bottom of the feeding assembly, so that the air pressure drives the dry ice particles to be sprayed by the spray gun, thereby achieving the purpose of cleaning the dirt. However, the dry ice particles used in the conventional dry ice cleaning equipment are relatively large and cannot be cleaned as desired. It is necessary to adjust the size of the dry ice granules sprayed, and it is easy to make the sprayed dry ice particles too large to cause damage to small and precise objects, and the tiny slits or corners cannot be cleaned, so most of them must be purchased separately. Machine, the dry ice granules are ground to the required thickness by the grinder and placed in the dry ice cleaning equipment, and then sprayed out through the spray gun for dry ice cleaning operation, so it is necessary to purchase a variety of different functions of the model to use together, the purchase cost Extremely high, however, although there are runners in the dry ice cleaning equipment, the dry ice falls into the trough of the runner, and then blown in by the intake pipe. The airflow passes through the air inlet passage and the air hole of the blowing member, and the airflow is ejected upward from the blowing nozzle, and the dry ice particles in the trough are ejected, and then fall downward through the inclined surface of the blowing member into the air outlet passage. The airflow blown into the trough is blown into the trough, so that the dry ice particles in the trough cannot be completely blown out, so that the dry ice particles sprayed from the spray gun are insufficient, and the cleaning effect is likely to be poor during washing.

The main purpose of this creation is to provide an effective solution to the shortcomings of conventional dry ice cleaning equipment.
