Abstract

The invention relates to a low-temperature quick freezing device, characterized by being provided with two stainless steel brazed plate-type cooling mechanisms (plate-type evaporators), wherein one of the two plate-type cooling mechanisms rotates forwardly and reversely relative to a specific shaft (the open and closure relative to a rotating shaft can be realized on the basis of taking pneumatic cylinder transmission, hydro-cylinder transmission or motor transmission as a power mechanism), and then upper and lower refrigeration plates clamp an objected to be cooled for refrigeration; the upper refrigeration plate (100) is embedded and fixed on an upper cover plate structure (102), rotates around the rotating shaft (108), and forms an open-closure structure together with the lower refrigeration plate (200) rotationally, and the angle of the open-closure rotating angle of the open-closure structure is usually 0-60 degrees. The material to be cooled is placed on the lower refrigeration plate, the principle of freezing the material is a refrigeration mechanism that refrigeration parts directly absorb the heat of the material to be cooled in a conduction method, and the heat transfer efficiency of the device is far higher than that of the traditional self-cooling or forced convection air cooling method, thus the time of rapidly freezing the material to be cooled is greatly shortened. The quick freezing device has the advantages of simple structural design, small device volume, large operating space and the like; the safe reliability of operation staffs is ensured, and simultaneously the work efficiency of the operation staffs is greatly improved. As shown in the drawing, the quick freezing device comprises the upper refrigeration plate 100, the lower refrigeration plate 200, a left cover plate 101, the upper cover plate 102, a right cover plate 103, a front cover plate 104, a front radiating hole 105, a control touch screen 106 and the rotating shaft 108.

Description

A kind of quick-freezing plant that utilizes dull and stereotyped refrigeration

Affiliated technical field

The present invention relates to a kind of device of quick quick-frozen blood plasma, in this device, adopt two cold drawings (evaporimeter) to be frozen the direct face contact of thing conduction pattern refrigeration to clamping up and down, play snap frozen and keep to greatest extent being frozen thing and being rich in bioactivator.

Background technology

In each blood station, down town, after the separation of whole blood that collection is next goes out blood plasma, below needing earlier the blood plasma quick-frozen to be spent to-30, put into the freezer long preservation again.The equipment of quick-frozen blood plasma has three kinds at present: low temperature refrigerator, forced convertion refrigerator and face contact type instant freezer.The refrigeration modes of three kinds of equipment is respectively natural air convection current cooling, forced convertion cooling and three kinds of modes of face contact conduction cooling, and at last a kind of quick-frozen efficient height of dull and stereotyped instant freezer, the quick-frozen blood plasma time can foreshorten to 30 minutes usually and reach requirement with interior, can keep bioactivator in the blood plasma to greatest extent.The plasma bags that quick-frozen is simultaneously come out is smooth attractive in appearance, is convenient to packing.This type also is the inexorable trend of blood plasma quick freezing unit from now on.

Summary of the invention

Common flat instant freezer adopts upper and lower cold drawing usually, and one of them is fixed, the up and down mode of another one clamps cooled object, this mechanical motion mode has simple in structure, the characteristics of being convenient to assemble, but following shortcoming is arranged: 1, the up and down spacing of cold drawing little (common 20 centimetres), cause placement or recovery plasma bags operating space too small, the visual field is narrow, greatly influences operating efficiency.2, arm up and down between cold drawing processing ease directly touch cold drawing (50 degree), cause frostbite.3, the cold drawing spacing is too small, does not have the enough reaction time to allow operating personnel's arm extract out when equipment fault, and causes the hidden danger of being pressed from both sides.4, because the operating space is little, limits operating personnel usually and in some height, operate, the tall operator operation of need bending over, the short person will operate on tiptoe.

The cold drawing that the present invention has just the discarded common employing structure that moves up and down, and the structure of using upset (or flip-shell) instead have solved fully rationally that cold drawing moves up and down structure and the problems that produce.The technical scheme that adopts is last cold plate to be changed into around specific axle carry out the certain angle flip-flop movement, reduces the height of entire equipment then, and operating surface is set in a height that meets people's operating habit.

The specific embodiment

Accompanying drawing 1 and accompanying drawing 2 are that this equipment is formed schematic diagram.It has two board-like cooling-

parts

13,14, and wherein 14 is fixed, during open operation, and the electromagnetic valve of gas circuit conducting, by 15 (can be cylinder, hydraulic cylinder or electric operator) active force, 13 do 0～60 around 17 spends the adjustable motion of opening.Wherein 17 can finely tune up and down, can adjust and compress spacing (usually have 5～30 millimeters and adjust surpluses) between 13 and 14, can regulate the thrust between the

cold drawing

13 and 14 up and down by adjusting cylinder air pressure according to the thickness of plasma bags.Suitable thrust can better guarantee refrigeration.

Have cryogenic refrigerating system at device interior, the 1st, special-purpose cryogenic compressor, the 2nd, condensation radiator efficiently, 13 and 14 is special two plate-type evaporators of refrigeration system, clamps cooled object by two plate-type evaporators and forces to conduct refrigeration and have higher refrigerating efficiency.Wherein 14 is fixed, and 13 can by special flexible hose 10, will carry out process of refrigerastion in the cold-producing medium importing 13 by certain angular turn folding.All mechanical movements of this equipment and process of refrigerastion be by the intelligent running of Programmable Logic Controller, makes equipment high efficiency, energy-conservation, easy and simple to handle or the like plurality of advantages.

This equipment is all-in-one, and all refrigeration, machinery, control assembly all concentrate in the cabinet, and control system adopts stability high Siemens's touch-screen and PLC Programmable Logic Controller, has data record, intelligent functions such as telecommunication network control and fault diagnosis.Because compact to design, whole set equipment is small and exquisite, takies less placement space.Equipment can move equipment very easily by the universal wheel that the body below is provided with.
