Description

TECHNICAL FIELD

[0001] The utility model is applied to the technical field of HPP sterilization, and particularly relates to a sealing plug of an ultrahigh-pressure bin body. BACKGROUND

[0002] HPP is a technology for food sterilization and preservation by using ultrahigh pressure, which is also called high-pressure sterilization technology. The food ultrahigh-pressure sterilization technology uses water or other liquid medium as a pressure transmission medium. The pressure applied to the liquid is transmitted through the medium, and the food placed in a specially sealed ultrahigh-pressure container is pressurized at room temperature or low temperature (below 20℃), and the pressure reaches several hundred megapascals, thereby achieving the purpose of sterilization. High pressure can affect the morphology of cells, such as causing vacuoles to rupture, thereby causing changes in morphology, and this destruction is irreversible. In addition, high pressure can also cause the inactivation of enzymes in food raw materials and microorganisms. Generally, when the pressure exceeds 300 MPa, irreversible denaturation of proteins occurs. Ultrahigh pressure can also damage cell membranes, change the permeability of cell membranes through high pressure, and inhibit the activity of enzymes and the replication of genetic materials such as DNA to achieve sterilization. HPP sterilization technology can kill a variety of bacteria, including but not limited to Escherichia coli, Listeria, Vibrio, heterakid nematode, yeast and mold, lactic acid bacteria, and mental nutrition bacteria. The application range of HPP technology is wide, and it is not limited to food processing sterilization, but also includes grapefruit juice debittering, meat tenderization, starch gelatinization, toxin and toxic protein inactivation, and increasing the gelatinization and bubble properties of protein food. The advantage of this technology is that it is a physical sterilization method, which can be used at room temperature and low temperature, and can better preserve the color, aroma, flavor and nutritional quality of food, without causing the destruction of nutritional components and changes in flavor as high-temperature sterilization does.

[0003] The current market super high pressure sealing bin mainly seals through the combination of the single layer rubber ring on the bin cover and the bin body and the locking mechanism, which is relatively cumbersome and needs manual intervention for locking or unlocking, and the single layer sealing rubber ring is prone to deformation under super high pressure, which greatly reduces the service life and does not meet the needs of efficient production of enterprises. The poor sealing of the super high pressure sterilization equipment not only leads to poor sterilization effect, but also has safety hazards. The sealing is one of the key factors of the super high pressure sterilization equipment, because it directly affects the sterilization effect and the safety of the equipment, if the sealing of the equipment is insufficient, a closed environment for super high pressure sterilization cannot be formed, which directly affects the sterilization effect, so that the activity of microorganisms and enzymes in the food cannot be effectively reduced or killed, thereby affecting the safety of the food. In addition, poor sealing easily leads to abnormal internal pressure of the equipment, if the pressure cannot reach the preset value, the safety valve cannot work normally, which increases the safety risk of the equipment during use. Therefore, it is necessary to provide a sealing plug of a super high pressure bin body, which has the advantages of compact structure, good sealing and high safety factor. Practical new type content

[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art, and provide a sealing plug of a super high pressure bin body, which has the advantages of compact structure, good sealing and high safety factor.

[0006] As can be seen from the above scheme, one end of the plug body is in sealing fit with the opening of the external bin body, and the other end of the plug body is connected with the output end of the external pressure booster. The plug body is in abutting fit with the inner wall of the external bin body, so that preliminary sealing is realized. The high-pressure water flow of the external pressure booster flows into the water inlet holes through the water injection channel, and then uniformly injects water flow into the sealing cavity of the external bin body. The water flow flows into the inner part of the open end of the first sealing ring and the bottom of the third sealing ring through the sealing water channel and the sealing water through hole respectively. With the continuous increase of the pressure in the bin body, the water pressure pushes the open end of the first sealing ring to expand outward and press the inner wall of the external bin body and the second sealing ring, and the water pressure pushes the third sealing ring to expand outward, so that the second sealing ring and the first sealing ring can tightly adhere to the inner wall of the external bin body, and the third sealing ring can prevent the water flow from flowing out of the gap between the second sealing ring and the stepped groove. If the pressure is greater, the sealing performance is better, and the plug body can be easily taken out after pressure relief, so that the efficiency is higher.

[0008] One preferred scheme is that the water inlet holes are arranged in the middle part of the cover, and the water outlet end of the plug body is provided with a water storage groove matched with the water inlet holes.

[0009] One preferred scheme is that the first sealing ring is a U-shaped sealing ring, the second sealing ring is a metal ring sealing ring, and the third sealing ring is an expansion sealing ring. The metal ring sealing ring is connected with the stepped groove, the expansion sealing ring is arranged at the end of the metal ring sealing ring away from the cover and matched with the stepped groove, and the mounting ring is arranged between the end of the metal ring sealing ring away from the cover and the expansion sealing ring.

[0010] One preferred scheme is that the end of the metal ring sealing ring in contact with the stepped groove is provided with a guide slope, the high-pressure water enters the gap between the metal ring sealing ring and the stepped groove through the sealing water through hole and the guide slope and is matched with the expansion sealing ring.
