Description

Technical Field

[0001] The utility model relates to the technical field of dry ice crushing, in particular to a reciprocating sliding dry ice crushing device. Background Art

[0002] The principle of dry ice cleaning is to mix and accelerate dry ice with compressed air. The dry ice gradually vaporizes in the pipeline, and finally the completely vaporized dry ice particles hit the dirt on the surface to be cleaned at high speed. The cleaning steps of existing dry ice cleaning equipment usually use a crushing mechanism to split large pieces of dry ice into dry ice particles, and then mix the dry ice particles with compressed air. The dry ice crushing mechanism is mostly a turntable type. When the turntable dry ice crushing mechanism is working, the dry ice particles are temporarily stored in the through hole on the turntable. The axis of the compressed air channel is parallel to the axis of the through hole, and the turntable rotates relative to the compressed air channel.

[0003] However, during the use of the turntable dry ice crushing mechanism, due to the low temperature caused by the dry ice environment, the turntable and the shell will experience varying degrees of deformation, and the turntable will often get stuck, which will lead to blockage of dry ice particles and affect the efficiency and effect of dry ice cleaning. In order to ensure that the turntable dry ice crushing mechanism produces uniform dry ice particles, the processing dimensional accuracy and assembly dimensional accuracy of the turntable must be extremely high, which greatly increases the manufacturing cost. Patent documents have now been published to improve this.

[0004] For example, Chinese patent CN215278943U relates to a reciprocating sliding dry ice crushing device and dry ice cleaning equipment, wherein the interior of the housing of the device has a sliding channel for the sliding plate to slide back and forth. An air inlet is provided at the top of the sliding channel, an ice outlet is provided at the bottom of the sliding channel, and an ice adding port is provided on the housing. A first sealing structure is provided at the air inlet, and a penetrating ice storage hole is provided on the sliding plate. The ice storage hole has an ice storage chamber composed of an ice storage hole and a sliding channel, and dry ice particles are stored in the ice storage chamber, and the ice storage state moves toward the ice outlet with the sliding of the sliding plate, and the ice outlet state is that the air inlet and the ice outlet are connected to the ice storage hole, and the dry ice particles are mixed with gas and discharged from the ice outlet. The reciprocating sliding ice delivery structure in the device reduces the manufacturing cost, makes the ice outlet more uniform, improves the stability of the dry ice cleaning equipment, and improves the cleaning effect.

[0005] Although the above patent reduces the manufacturing cost through the reciprocating sliding ice delivery structure, makes the ice output more uniform, and improves the stability of the dry ice cleaning equipment, the dry ice is easily blocked in the funnel during the process of adding dry ice, resulting in a slow discharge speed of the dry ice in the funnel, affecting the efficiency of dry ice crushing.
