Technical Field

The invention belongs to the technical field of ultrahigh pressure, and particularly relates to cylinder body moving direct-pressure type ultrahigh pressure equipment and a using method thereof.

background

the isostatic pressing technology is an ultrahigh pressure technology developed according to the Pascal principle, and is widely applied to the fields of chemical industry, powder metallurgy, metal forming, food sterilization and preservation and the like. In a typical process, a substance to be treated in a flexible package is subjected to a pressure treatment in a closed ultrahigh-pressure vessel by a pressure medium. If the pressure range in the ultrahigh pressure container using water as the pressure transfer medium is 400-600 MPa, when the pressure transfer medium is changed into high-grade hydraulic oil, the processing pressure in the ultrahigh pressure container can be increased to 1000MPa or even higher. A large number of experiments prove that high pressure has a good sterilization effect, and the high pressure can cause the morphological structure, biochemical reaction and genetic mechanism of microorganisms and the structure and function of a cell wall membrane to be changed in many aspects. Thereby affecting the original physiological function of the microorganism and even destroying the original function to generate irreversible change.

Most bacteria can grow under 20-30 MPa, and pressure-resistant microorganisms can grow under the pressure higher than 40-50 MPa, so that the treatment pressure exceeding 200MPa is generally adopted when the ultrahigh pressure technology is adopted for treatment, and the ultra-high static pressure generated by ultrahigh pressure not only influences the morphology of cells, but also can destroy weak bonding bonds such as hydrogen bonds. The major components in cell membranes are phospholipids and proteins, the structure of which is maintained by hydrogen and hydrophobic bonds. Under the action of pressure, protein is denatured in cell membrane, amino acid essential for cell growth is inhibited, in addition, the permeability of cell membrane is increased by high pressure, cell components flow out, the function of cell is damaged, the process finally causes pressure coagulation of protein and inactivation of enzyme, and various cell injuries such as leakage of components in cell and cell membrane rupture are generated, and the process belongs to cold treatment sterilization.

The ultrahigh pressure treatment technology is mainly realized through ultrahigh pressure treatment equipment, the ultrahigh pressure equipment mainly comprises a high-pressure container, a frame, a pressurization system and a control system, the treatment principle is that a processed object is placed in a specific harness, the harness filled with a workpiece is placed in the ultrahigh pressure container filled with liquid, the pressurization is gradually carried out through the pressurization system, and then the pressure is transmitted through hydraulic pressure, so that each surface of the object is subjected to equal pressure. During the compression process, the properties, even the chemical nature, of the material being compressed are caused to change. The existing ultrahigh pressure equipment is divided into a vertical type and a horizontal type according to the structure.

Traditional vertical ultra-high pressure equipment, in the in-process that equipment used the filling material, often adopted the mode that the equipment frame moved about for high-pressure vessel, made high-pressure plunger take off high-pressure vessel and avoided high-pressure vessel upper mouth to carry out the operation of filling the material, high-pressure vessel kept the rigidity this moment, and made high-pressure vessel break away from the frame restraint. In actual production, more and more customers of an automatic production line need a plurality of ultrahigh-voltage equipment to be combined into a production line. On the production line that has many extra high pressure equipment, because need the frame to remove different positions, can block the operation of the material transfer chain on the production line, lead to the production efficiency of the production line that the extra high pressure equipment constitutes low. In addition, because hoisting equipment is often required to be configured in the production and processing process, the frame can easily interfere with the hoisting equipment in the reciprocating movement process. Or the lifting device has to be lifted above the frame in order not to interfere with it, thus affecting the efficiency of the work.
