Abstract

The invention relates to an air pressure ejection instant starting device, which comprises a launching tube. One end of the launching tube is provided with an end cover, and the other end of the launching tube is provided with a locating sleeve; a launching rod is coaxially arranged in the launching tube; a piston is positioned on a rod segment, which is arranged in the launching tube, of the launching rod; a pressure storage cavity is enclosed by the end surface facing the end cover of the piston, the side wall of the launching tube and the end cover; a normal pressure cavity is enclosed by the end surface facing the locating sleeve of the piston, the side wall of the launching tube and the locating sleeve; a counter hole is axially formed in the end surface, which faces the end cover, of the launching rod; the hole position of the counter hole is provided with a baffle cover; the baffler cover is fixed on the launching rod; a screw rod is arranged in the axial direction of the launching rod and extended into the counter hole; a nut is arranged in the counter hole and screwed on the screw rod; the screw rod is in transmission connection with a power output end of a speed reducer; and the location sleeve is provided with a launching rod locking device used for locking the launching rod. The air pressure ejection instant starting device is rapid in starting, stable in working performance and large in working stroke, and has long service life.

Description

technical field [0001] The invention relates to an instant opening device for pneumatic ejection. Background technique [0002] In the steam flash explosion process used to process straw and other materials, it is required to use the valve opening device to completely open the valve closing the tank body in the shortest possible time, so that the material in the tank body can transition from the pressure state of 2-4MPa in an instant To the normal pressure state, so as to realize the ideal steam flash explosion operation. However, the existing valve opening device usually takes 15-20 seconds to fully open the valve. Due to the slow opening speed, the tissue structure of a large amount of materials cannot participate in the flash explosion and breaks the wall, which seriously affects the materials processed by steam flash explosion. quality and effect. Contents of the invention [0003] The purpose of the present invention is to provide a fast opening action, stable worki...
