Abstract
The utility model relates to a cooling device, which is composed of a box body and a box cover. The utility model is characterized in that the box body is provided with an inner wall and an outer wall which are insulated by vacuum in the middle, heat preservation and thermal insulating materials are filled between the two walls, a partition board is arranged in the box and divided the box into a cold liquid chamber and a cooling chamber, the edges of the board are communicated, a liquid-delivery valve is arranged on the side wall of the cold liquid chamber, an air outlet valve and an air-pressure gage are arranged on the side wall of the cooking chamber, and the bottom of the box body and the lower part of the partition board are provided with bearing pads. The utility model has the advantages of simple structure, normative operation, high safety, uniform cooling of contraction components, low cost and short time of contraction.
Description
The utility model relates to a kind of refrigerating plant, is used for the cold charge machine of shrinkage apparatus assembly when to be that a kind of equipment is cold specifically install.
Existing all kinds of refrigerating plant all needs consumes energy as refrigerator, refrigerator-freezer etc., the shrinkage of incompatibility main equipment assembly.At present, the cold installation of on-the-spot main equipment is that dry ice and assembly are put into interim casing with carbon dioxide usually, and the outside is surrounded by cotton-wadded quilt, carries out shrinkage.This method falls behind, and there is potential safety hazard in operation.Dry ice cost height, the shrinkage effect is undesirable.Another kind method is that assembly turning is dwindled.
The purpose of this utility model provides a kind of simple in structure, need not any energy, can adopt lower-cost liquid nitrogen as cold-producing medium, does not damage assembly, and refrigeration is fast, and shrinkage is effective, working specification, the cold installation of safe and reliable equipment cold charge machine.
The utility model is to realize like this, it is to be made of casing and case lid, it is characterized in that casing is provided with inside and outside wall, vacuum insulation, fill heat-insulation material, be provided with dividing plate in the case, the edge communicates, and dividing plate will be divided into cooling liquid chamber and cool room in the case, on cooling liquid chamber's sidewall, be provided with fluid-delivery valve, on the cool room sidewall, be provided with air bleeding valve and gas gauge, and the pressure-bearing pad be housed, between case lid and casing, be provided with sealing ring at bottom half and the lower partition.
The utility model also is provided with spill valve on the sidewall of cooling liquid chamber.
The utility model has the advantages that:
One, whole apparatus structure is simple, need not any energy, and working specification is safe and reliable.
Two, adopt liquid nitrogen to make cold-producing medium, the container adiabatic heat-insulation; Container is divided into gas, liquid two parts, and the shrinkage part is caught a cold evenly, has avoided the local low cold embrittlement that causes; Cost is low, and the shrinkage time is short, and is effective.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is a structural representation of the present utility model.
Referring to accompanying drawing 1, the utility model is to be made of casing and case lid, it is characterized in that being provided with in the casing inside and outside wall 9,4, the utility model is owing to adopt liquid nitrogen as cold-producing medium, its inwall 9 adopts low temperature resistant, withstand voltage metal, outer wall 4 is a general steel plate, middle vacuum insulation is filled heat-insulation material 5, and available perlite is made the insulation heat-insulating material, in casing, be provided with dividing plate 7, the edge communicates, and dividing plate 7 is provided with fluid-delivery valve 6 with being divided into cooling liquid chamber 12 and cool room 13 in the case on cooling liquid chamber's 12 sidewalls, link to each other by metal threaded pipe with the liquid nitrogen storage tank of peripheral hardware, on the another side sidewall of cooling liquid chamber 12, be provided with spill valve 10; On cool room 13 sidewalls, be provided with air bleeding valve 11 and gas gauge 3, between case lid and casing, be provided with sealing ring 2.Bottom half and the lower partition are equipped with pressure-bearing pad 8.
When needs carry out shrinkage to assembly, to open fluid-delivery valve 6 liquid nitrogen and enter in the cooling liquid chamber 12, nitrogen enters cool room 13, discharges at air bleeding valve 11 gases.The row's of giving shrinkage assembly of control liquid, gas, it can narrow down to desired value with the shrinkage part in 2-4 hour.
Claims (2)
