Description

Technical Field

[0001] The utility model relates to the technical field of dry ice manufacturing, in particular to a continuous block forming mechanism of a vertical dry ice manufacturing machine. Background Art

[0002] Dry ice is solid carbon dioxide. It is a white solid that looks like ice and snow. It vaporizes directly when heated without melting, hence the name dry ice. Its melting point is -56.6°C (5.2 atmospheres) and its density is 1.56g / cm 3 (179°C), with a face-centered cubic lattice.

[0003] Dry ice can be made from liquid carbon dioxide by continuously producing CO2 snow and by directly compressing dry ice in a compression chamber. It is mainly used as a cleaning agent and refrigerant. For example, it is used as a cleaning agent in industrial molds, petrochemicals, printing industry, automobile and ship cleaning, etc.; it is used as a refrigerant in food, hygiene, medical treatment, scientific research and other fields. When dry ice is formed into blocks, a vertical dry ice maker is used, and the block forming operation is performed through the continuous block forming mechanism in the vertical dry ice maker.

[0004] Prior art such as the utility model with publication number CN207659102U, the utility model discloses a vertical dry ice making machine, including a body frame, a lower fixing plate is fixedly installed on the top side of the body frame, a lower main hydraulic oil cylinder is fixedly installed on the bottom side of the lower fixing plate, the output shaft of the lower main hydraulic oil cylinder passes through the lower fixing plate, and a lower template of the ice making bin is fixedly installed, an upper fixing plate is arranged above the lower fixing plate, an upper main hydraulic oil cylinder is fixedly installed on the top side of the upper fixing plate, an ice making bin is fixedly installed on the bottom side of the upper fixing plate, and an inlet is opened on the top of one side of the ice making bin A liquid pipe interface and an ice making bin exhaust gas outlet opened at the bottom of the ice making bin are provided on one side adjacent to the liquid inlet pipe interface. Fixed blocks are fixedly installed at the four corners of the bottom side of the body frame, and a cavity is opened on the fixed block. The utility model can effectively avoid uneven overall density of dry ice caused by uneven feeding, and at the same time, it is convenient for the body frame to have an effective buffering effect during movement, which solves the problem that the existing original horizontal dry ice making machine has a higher dry ice density at the bottom and a lower dry ice density at the top after dry ice extrusion molding due to uneven feeding distribution during the production process, and at the same time, the dry ice making machine is not easy to move.

[0005] The inventor discovered in his daily work that the continuous block-forming mechanism of the existing vertical dry ice making machine cannot automatically unload materials during the continuous block-forming process. The dry ice blocks need to be manually removed before the continuous block-forming mechanism can continue the block-forming operation. When the manual removal takes a long time, it may cause a brief pause in the subsequent dry ice briquetting process, and it is impossible to achieve very smooth and uninterrupted continuous block-forming, which in turn causes the existing equipment to require manual unloading, resulting in the problem of pauses and unsmooth continuous block-forming.

Through the above components, after the dry ice is formed, the second cylinder can cooperate with the sealing plate to push the formed dry ice, thereby reducing the phenomenon that the dry ice blocks are stuck in the upper mold and cannot be unloaded.

[0013] Preferably, four guide posts are fixedly connected to the surface of the sealing plate, and the guide posts are slidably connected to the inner wall of the upper mold. Through the above components, the four guide posts can improve the stability of the sealing plate when it moves.
