Abstract
The utility model relates to a novel frozen screw rod ammonia machine and belongs to the field of refrigeration techniques. The novel frozen screw rod ammonia machine comprises an oil separator, an ammonia releasing decompression valve and an oil return pipe. An ammonia gas pipe is connected between the ammonia releasing decompression valve and the oil return pipe. The joint position of the ammonia gas pipe and the ammonia releasing decompression valve and the joint position of the ammonia gas pipe and the oil return pipe are sealed. According to the novel frozen screw rod ammonia machine, a conventional frozen screw rod ammonia machine is improved, recycle of ammonia is realized, pollution to the air is reduced, waste of ammonia gas is avoided, and maintenance is facilitated. Meanwhile, the novel frozen screw rod ammonia machine is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of Novel freezing screw rod ammonia machine, belongs to the Refrigeration Technique field.
Background technology
At present in freezing industry, usually use freezing screw rod ammonia machine, usually be equipped with one and let out the ammonia pressure loading valve on the freezing screw rod ammonia machine equipment oil eliminator of routine, this lets out the ammonia pressure loading valve is when freezing screw rod ammonia machine emerged in operation failure situations the time, ammonia in oil eliminator is released by letting out the ammonia pressure loading valve, usually letting out the ammonia pressure loading valve is not take over what interface, in case be in an emergency, limited amount ammonia can only be put into air, can produce air like this and pollute, simultaneously, also cause the waste of ammonia; Especially, the release of ammonia is in maintenance process, can damage the maintenance personal like this, makes troubles to operation; Therefore necessary freezing screw rod ammonia machine to routine improves, and addresses this problem.
The utility model content
For the problems referred to above, the utility model proposes a kind of Novel freezing screw rod ammonia machine, improve by the freezing screw rod ammonia machine to routine, realize recovery again, the utilization of ammonia, reduce the pollution to air, avoided the waste of ammonia, facilitated maintenance; Simultaneously, simple in structure, handled easily.
For arriving specification requirement, the technical solution adopted in the utility model: a kind of Novel freezing screw rod ammonia machine, comprise oil eliminator 1, let out ammonia pressure loading valve 2, oil return pipe 3 connects an ammonia pipe 4 on letting out between ammonia pressure loading valve 2 and oil return pipe 3.
Described ammonia pipe 4 and the junction sealing of letting out ammonia pressure loading valve 2, oil return pipe 3.
Described ammonia pipe 4 adopts steel pipe to make.
Described oil eliminator 1 is let out ammonia pressure loading valve 2, oil return pipe 3, and ammonia pipe 4 is commercially available common components.
The beneficial effects of the utility model: the utility model improves by the freezing screw rod ammonia machine to routine, realizes recovery again, the utilization of ammonia, reduces the pollution to air, has avoided the waste of ammonia, has facilitated maintenance; Simultaneously, simple in structure, handled easily.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1
-Oil eliminator, 2-let out ammonia pressure loading valve, 3-oil return pipe, 4-ammonia pipe.
The specific embodiment
Below in conjunction with accompanying drawing and implementation process, the utility model is described further, understands to facilitate the technical staff.
As shown in Figure 1: a kind of Novel freezing screw rod ammonia machine, comprise oil eliminator 1, let out ammonia pressure loading valve 2, oil return pipe 3 connects an ammonia pipe 4 on letting out between ammonia pressure loading valve 2 and oil return pipe 3.
Described ammonia pipe 4 and the junction sealing of letting out ammonia pressure loading valve 2, oil return pipe 3.
Described ammonia pipe 4 adopts steel pipe to make.
The course of work of the present utility model: freezing screw rod ammonia machine in the course of the work, in case break down, can open when needing repairing and let out ammonia pressure loading valve 2, because connect an ammonia pipe 4 on letting out between ammonia pressure loading valve 2 and oil return pipe 3, this moment, ammonia just can enter in oil return pipe 3 along ammonia pipe 4, by the oil return process, can realize recovery and the utilization of ammonia.
The utility model improves by the freezing screw rod ammonia machine to routine, realizes recovery again, the utilization of ammonia, reduces the pollution to air, has avoided the waste of ammonia, has facilitated maintenance; Simultaneously, simple in structure, handled easily.
The utility model describes by accompanying drawing, in the situation that do not break away from the utility model scope, can also carry out various conversion and be equal to replacement the utility model patent, therefore, the utility model patent is not limited to disclosed specific implementation process, and should comprise the whole embodiments that fall in the utility model Patent right requirement scope.
