Problems solved by technology

Although this patent speeds up the drainage speed of low-pressure pipelines and solves the problem of slow pressure relief and drainage speed of large-capacity ultra-high pressure vessels, this patent cannot quickly relieve the pressure of high-pressure pipelines in a high-pressure state, and cannot make ultra-high pressure The high pressure in the container is relieved outwards to ensure the safety of the ultra-high pressure container

Embodiment approach

[0060] According to a preferred embodiment, the outer side of the load-bearing frame of the present invention is a load-bearing frame with a broken line structure with an inner angle of 120° to 140°. The zigzag structure is formed by cutting off four corners of each layer of rectangular plates along a consistent tangent line, and the extension lines of the tangent lines intersect each other to form a parallelogram. Preferably, the extension lines intersect to form a square. The mutual contact area between each layer of steel plates is greater than 80% of their relative areas, and the ratio of the width of the gap between two groups of plates to the thickness of each group of plates is 1-3:1, preferably 2.5:1. In addition, the ratio of the width of the inner frame of the load-bearing frame to the thickness of the frame is 2 to 1:1, preferably 1.5:1; in addition, the aspect ratio of the inner frame is 5 to 6:1, preferably 6 :1, the aspect ratio of the outer frame is 2-4:1, prefe...

Embodiment 1

[0084] The preparation process of the load-bearing frame at least includes: the pre-assembly of the alloy steel plates of the load-bearing frame, the alignment and adjustment of the opening arcs of the alloy steel plates of the load-bearing frame, and the welding of the alloy steel plates of the load-bearing frame. The assembly process of the first load-bearing frame or the second load-bearing frame specifically includes: using 38 pieces of M27*200mm outer hexagon bolts to pre-assemble 6 pieces of stacked plates on the flat plate, and at the same time, it is necessary to ensure that each piece of load-bearing frame cannot have For flash, burrs, bumps, and oil stains, the placement of the workpiece should be consistent with the placement of the water cutting process. The upper and lower parts should choose R435 water cutting with the best quality; place the two semicircular blocks in the arcs on both sides of the 6 load-bearing frames. , and connect the two semi-circular blocks ...

Embodiment 2

[0090] In this embodiment, on the basis of Embodiment 1, the pressure relief device is further described.

[0091] The pressure relief device for an ultrahigh pressure sterilization device of the present invention includes an ultrahigh pressure chamber, at least one ultrahigh pressure source, a booster linear valve, at least one pressure sensor, at least one proportional pressure relief valve and a control module. The control module adjusts the boosting slope of each pressure stage based on the ultra-high pressure indication in the ultra-high pressure cabin monitored by the pressure sensor and the boost linear valve connected to the ultra-high pressure source, so that the ultra-high pressure approaches a sinusoidal waveform The changing curve of the rising curve is rapidly boosted. After the ultra-high pressure in the ultra-high pressure cabin is stabilized, the control module adjusts at least one proportional pressure relief valve connected to the ultra-high pressure pipeline...

Abstract

The invention relates to a pressure relief device for an ultrahigh pressure sterilization apparatus. The pressure relief device comprises an ultrahigh pressure cabin, at least an ultrahigh pressure source, at least a pressure sensor, at least a decompression valve and a control module. the invention is characterized in that ultrahigh pressure in the ultrahigh pressure cabin reaches a preset threshold value under pressurization of the ultrahigh pressure source; the control module gives instructions to the decompression valves to carry out at least one fast pressure relief on the basis of the preset threshold value of the ultrahigh pressure in the ultrahigh pressure cabin monitored by the pressure sensor such that ultrahigh pressure inside the ultrahigh pressure cabin is suddenly reduced. The decompression valves are arranged inside end caps for sealing two sides of the ultrahigh pressure cabin. The decompression valve comprises at least two decompression disks which are coaxially arranged and close fit with each other. At least two of the decompression disks make decompression areas on the decompression disks to be superposed or separated in an independent rotating mode so as to carry out pressure relief or pressure sealing. Pressure in the ultrahigh pressure cabin changes stably, and service life is prolonged.

Description

technical field [0001] The invention relates to the field of ultrahigh pressure technology, in particular to a pressure relief device for an ultrahigh pressure sterilization device. Background technique [0002] Food ultra-high pressure sterilization technology is to apply a pressure of 400-600 MPa to soft-packaged food and other materials in a closed ultra-high-pressure container with water as a medium, or apply a pressure of 100-1000 map with high-grade hydraulic oil. This kills almost all bacteria, mold and yeast in it without destroying nutrients and changing flavors like pasteurization. Ultra-high pressure processing (ultra-high pressure processing) is referred to as UHP, also known as ultra-high pressure technology, high static pressure technology, or high-pressure food processing technology. [0003] Chinese patent CN201621464U discloses a rapid pressure relief system for ultra-high pressure vessels, which is characterized in that three parallel pressure relief pipel...
