Energy-storing valve opening device of steam explosion machine

Abstract

The invention discloses an energy-storing valve opening device of a steam explosion machine. The energy-storing valve opening device is capable of improving steam explosion effect greatly and comprises a storage tank. A seal cover is disposed at a feeding inlet of the storage tank. A discharge outlet of the storage tank is connected to a side wall of a valve opening barrel in a sealed manner. The discharge outlet is communicated with an inner cavity of the valve opening barrel. A piston which is used for sealing the discharge outlet is disposed in the inner cavity of the valve opening barrel. The piston of the valve opening barrel is contacted with an inner cavity wall in a sealed manner. The piston can slide reciprocatingly in the inner cavity. One end of the valve opening barrel is connected to a valve opening cylinder in a sealed manner. An inner cavity of the valve opening cylinder is mutually partitioned with the inner cavity of the valve opening barrel in a sealed manner. A discharging opening is reserved at the other end of the valve opening barrel. A piston of the valve opening cylinder separates the inner cavity of the valve opening cylinder into a pressurizing cavity and an energy-storing cavity. A pressurizing cavity air venting pipe is disposed on the side wall of the pressurizing cavity. An energy-storing cavity air inlet pipe is disposed on the side wall of the energy-storing cavity. A piston rod is connected between the piston of the valve opening cylinder and the piston of the valve opening barrel. Air holes are reserved on the side wall of the valve opening barrel.

Description

Technical field [0001] The invention relates to a steam explosion machine for performing physical blasting pretreatment of various agricultural straws, in particular to a valve opening device in the steam explosion machine. Background technique [0002] The steam explosion machine is currently mainly used in the pretreatment process of liquor brewing, feed production, starch processing and other industries. It is an equipment used for physical blasting pretreatment of cellulose, hemicellulose, and lignin of various straw materials. Its main working principle is: put the chopped straw into the storage tank, then pass high-temperature steam into the tank, then pressurize it for a period of time, and finally open the tank quickly to make the material burst within 0.01 second. The temperature and pressure are lowered in an instant to achieve the purpose of dividing and separating cellulose, lignin, hemicellulose and other tissues in the material. Whether the discharge valve can be o...

Problems solved by technology

The disadvantage of this method of hydraulically driving the ball valve switch is that the response speed is slow, and it is difficult to realize the purpose of instantly opening the discharge ball valve, so it is also difficult to achieve the technical effect of steam explosion
