Description

Technical Field

[0001] The utility model relates to the technical field of steam flash explosion, in particular to a steam flash explosion fast door opening device. Background Art

[0002] Steam explosion is a technology that uses high-temperature and high-pressure steam to instantly explode to treat organic waste. It converts urban domestic organic waste into useful organic fertilizer by treating it with high-temperature and high-pressure steam. This method changes the traditional way of waste disposal and reduces environmental pollution, such as the formation of harmful gases, dust and haze. In addition, steam explosion is also a natural phenomenon, mainly used in the pretreatment of biomass. When the steam explosion device is in use, a quick-opening door device is required to close or open it to ensure the safe use of the steam explosion device.

[0003] After searching, the patent publication number CN116674894A discloses a patent named a new type of instantaneous steam flash explosion fast door opening device. The technical problem to be solved is that when the sealing cover is opened, the material discharged from the discharge port is easy to contact with the sealing cover and change direction, which is not conducive to the collection of the material. The sealing structure of the sealed discharge box adopts a segmented structure, so the discharge box can be opened faster, the speed of opening the flash explosion tank body is improved, and the material will not be affected by the change of direction when falling, which is conducive to the collection of the material; but there are still the following disadvantages that need to be solved: relying solely on the hydraulic push rod cannot guarantee the sealing effect between the two sealing barrels.
