Sealing structure for dry ice batching disc

Abstract

The invention discloses a sealing structure for a dry ice batching disc, and relates to the technical field of dry ice cleaning machine accessories. The sealing structure comprises an upper disc body and a lower disc body, the upper disc body and the lower disc body are vertically aligned, the upper disc body and the lower disc body are fixed through bolts in a matched manner, a rotating disc is arranged in the position between the upper disc body and the lower disc body in a matched manner, a first circular clamping groove is formed at the outer side of a circular separation ring, and a first sealing ring is arranged in the first circular clamping groove in an interference fit manner. Second circular clamping grooves are concentrically formed in the upper face and the lower face of the rotating disc, meanwhile, third circular clamping grooves are formed in the outer side face of the rotating disc in the circumferential direction, second sealing rings are arranged in the second circular clamping grooves in an interference fit manner, and third sealing rings are arranged in the third circular clamping grooves in an interference fit manner. Through arrangement of the first sealing ring, the second sealing rings, the third sealing rings and ice outlet through grooves and cooperation of components, the internal air tightness of the structure is good in use, meanwhile, the structure can effectively avoid blockage of dry ice, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of dry ice cleaning machines, and in particular relates to a sealing structure for a dry ice batching tray, which is mainly used for sealing the inside of the batching tray in the dry ice cleaning machine. Background technique [0002] In the cleaning process of automobiles, electromechanical equipment, electrical equipment, etc., in order to avoid damage to the interior of the equipment due to cleaning, people gradually use dry ice cleaning instead of ordinary cleaning. Dry ice cleaning machines are easy to use, high cleaning efficiency and will not damage The equipment is damaged. Therefore, the dry ice blasting machine is gradually favored by people. During the use of the dry ice blasting machine, the dry ice batching tray is an indispensable main accessory. When the dry ice batching tray is in use, it mainly removes the dry ice discharged from the hopper. Arrange according to a certain position and quant...
