Embodiment Construction
[0019] The supporting quick-opening material feeding cover on the LB-1500 type numerical control continuous steam explosion machine is the concrete implementation of the above-mentioned invention. The feeding cover has a diameter of 1.2 meters and a self-weight of 1.2 tons. It can withstand a maximum internal pressure of 4MPa. It takes about 12 seconds to open or close each time, which improves the working efficiency of large and medium-sized industrial continuous steam explosion equipment.

Abstract
The invention relates to a quick-opening material feeding cover matched with a steam blasting machine, belongs to storage cover devices, and particularly provides a full-automatic quick-opening material feeding cover which is matched with the steam blasting machine and realized by a pneumatic control system. The material feeding cover acts according to the specific sequence of unscrewing, lifting and moving out as well as moving back, pressing down and screwing, so as to be quickly opened and closed; a bottom sealing assembly and the cover opening are pressed tightly by the internal pressure of a container to form sealing; furthermore, the bottom sealing assembly is staggered with the teeth of the cover opening through small-angle rotation, so as to realize axial locking. The material feeding cover can be completely moved out from a horizontal track, so as to completely expose a feeding hole. The structure of the full-automatic quick-opening material feeding cover disclosed by the invention is free of a bolt fastening piece, can be adapted to high-frequency quick-opening material feeding operation, and can be used for operating the heavy cover with a weight more than 1 ton; the full-automatic quick-opening material feeding cover can stably and reliably operate.
Description
technical field [0001] The invention relates to a quick-opening feeding cover matched with a steam explosion machine, which is a bin cover type device. Background technique [0002] The steam explosion machine is a kind of equipment used for biomass pretreatment. The objects it deals with include crop stalks, energy crops, organic waste, etc. Since the internal pressure of the explosion chamber of the steam explosion machine can reach up to 4MPa when it is working, the feeding cover of the explosion chamber must have a considerable structural strength, and in order to ensure fast feeding, the diameter of the feeding cover should be enlarged as much as possible, so that the industrial-grade feeding The self-weight of the cover can reach more than 1 ton, which is a special requirement for the automatic quick-opening material cover of the steam explosion machine. First of all, the feeding cover bears a large internal pressure of the explosion chamber, and its locking mechanis...
