Abstract
The invention discloses an energy-saving deep cooling box for deeply cooling materials or workpieces, and belongs to the technical field of deep cooling treatment equipment. The energy-saving deep cooling box comprises a liquid nitrogen storage tank, a liquid nitrogen delivery pipe, a check valve, a deep cooling box, electric valves, a liquid nitrogen spray pipe, a fan, a nitrogen discharge pipe, a nitrogen recovery tank and the like. The energy-saving deep cooling box is characterized in that a fin-type heat preservation pipe (12) is arranged in the box body (16) of the deep cooling box in the prior art, one end of the fin-type heat preservation pipe (12) is connected with the liquid nitrogen storage tank (1) through the second electric valve (6) and the liquid nitrogen delivery pipe (3), and the other end of the fin-type heat preservation pipe (12) is connected with the nitrogen recovery tank (10) through the third electric valve (8) and the nitrogen discharge pipe (9). The energy-saving deep cooling box has the advantages of reducing the consumption of liquid nitrogen and reducing the production cost.
Description
Technical field
The invention belongs to the subzero treatment equipment technical field, be specifically related to a kind of energy-conservation deep cooling box.
Background technology
At present; Be to carry out at the deep cooling box that material, workpiece are adopted when carrying out subzero treatment both at home and abroad with the mode of heat convection; Be about to liquid nitrogen direct gasification in jet pipe sprays into deep cooling box, utilize gasification latent heat and low temperature nitrogen to absorb heat the temperature in the deep cooling box is reduced.The material or the workpiece that are placed in the case reach the purpose of subzero treatment through heat exchange for a long time.Temperature retention time is long more under cryogenic environment, and it is more abundant that retained austenite is changed, and forms better carbide particle, the better effects if of subzero treatment.But to keep the temperature that the subzero treatment requirement reaches for a long time, with regard to otherwise spray the nitrogen process with stopping, can cause the lot of consumption of liquid nitrogen, the production cost of subzero treatment is increased.
Summary of the invention
The object of the invention provides a kind of deep cooling box of new construction, can overcome the shortcoming that exists in the prior art effectively.
The present invention is achieved in that as shown in Figure 1, and it includes liquid nitrogen storage tank (1), stop valve (2), defeated liquid nitrogen pipe (3), control panel (4), first motor-driven valve (5); Second motor-driven valve (6); Steam vent (7), the 3rd motor-driven valve (8), denitrogen tracheae (9), nitrogen recycling jar (10), deep cooling chamber door (11); Fin type insulating tube (12); Liquid nitrogen jet pipe (13), temperature sensors (14) etc. is characterized in that in existing deep cooling box casing (16), being equipped with a fin type insulating tube (12); This insulating tube one end is connected with liquid nitrogen storage tank (1) with defeated liquid nitrogen pipe (3) through second motor-driven valve (6), and the other end is connected with nitrogen recycling jar (10) with denitrogen tracheae (9) through the 3rd motor-driven valve (8).
Advantage of the present invention and good effect are the consumption that can reduce liquid nitrogen, reduce production costs widely.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the present invention is further specified
Fig. 1 structural representation of the present invention

Fig. 3 is the vertical view of Fig. 2
1-liquid nitrogen storage tank among the figure, the 2-stop valve; 3-fails liquid nitrogen pipe, 4-control panel, 5-first motor-driven valve, 6 second motor-driven valves, 7-steam vent, 8-the 3rd motor-driven valve, 9-denitrogen tracheae, 10-nitrogen recycling jar, 11-deep cooling chamber door, 12-fin type insulating tube, 13-liquid nitrogen jet pipe, 14-temperature sensor, 15-blower fan; 16-deep cooling box casing, the 17-motor, the 18-fin, A-imports liquid nitrogen, and B-discharges nitrogen.
The specific embodiment:
As shown in Figure 1, workpiece is placed in the deep cooling box casing 16, carry out subzero treatment by routine, promptly open the stop valve 2 and first motor-driven valve 5; Liquid nitrogen is by entering in the deep cooling box casing 16 through the defeated pipe 3 of liquid nitrogen in the liquid nitrogen storage tank 1, and starter motor 17 drives blower fan 15 and rotates, and liquid nitrogen is through 13 ejections of liquid nitrogen jet pipe, and liquid nitrogen gasifies in deep cooling box casing 16; Make temperature reduction in the deep cooling box casing 16, the workpiece of placing in the casing begins to carry out heat exchange, and workpiece temperature reduces, and the temperature sensor 14 of installation feeds back to control panel 4 with the temperature in the casing 16 in the casing; When temperature reaches the temperature of setting in refrigeration makes casing 14, open second motor-driven valve 6, close first motor-driven valve 5, stop motor 17; Liquid nitrogen gets in the fin type insulating tube 12, and after temperature reached setting value in the casing, second motor-driven valve 6 cut out, and the temperature in casing rises to setting value; The 3rd motor-driven valve 8 is opened, arranged the nitrogen in the insulating tube 12 after, the 3rd motor-driven valve 8 cuts out; Second motor-driven valve 6 is opened, and liquid nitrogen gets into insulating tube and carries out heat exchange, after temperature drops to setting value in the casing; Second motor-driven valve 6 cuts out, and so circulation keeps temperature in the casing, up to accomplishing setting of task.Reach like this and reduce liquid nitrogen consumption, the purpose that reduces production costs.
