Using refrigeration system, with water carrier, in the energized state by producing ice after a certain equipment.According to the principle and life of evaporator
The ice cube shaped of the difference of production mode, generation is also different；Ice machine is generally divided into particle ice maker, flake ice with ice shape by people
Machine, plate ice machine, tube ice machine, shell ice machine etc..Direct-cooling type ice machine its advantages are refrigerants after ice bank aluminium sheet pipeline, system
Water coke slurry heat of the cryogen by aluminium sheet directly and inside ice bucket, it is high-efficient.The feed liquid way base of direct-cooling type ice machine at this stage
This is all full-liquid type feed flow, therefore needs to fill a large amount of refrigerant in the aluminium sheet pipeline of direct-cooling type ice machine.Freeze feed flow
In mode: full-liquid type feed flow is a kind of more complicated feed liquid way, and the accessories such as pipeline, pressure vessel that system is related to are more multiple
Miscellaneous, machine operation is more complicated.Common refrigerant, although such as freon comparison it is safe, price is right high year by year
Atmosphere has destruction, and national policy level is also gradually to eliminate freon.Although ammonia refrigerant less expensive,
Safety is again relatively low, needs professional operator to take appointment with certificate, cost of labor is relatively high.In addition, novel hybrid refrigeration
Agent R407C, R404a, R417a etc., price is higher, and efficiency and cost be not directly proportional.So direct-cooling type ice machine needs pass through
It is few to reduce cost with refrigerant to reach.
Utility model content
The purpose of this utility model is to provide a kind of inexpensive direct-cooling type ice machines, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the utility model provides the following technical solutions:
A kind of low cost direct-cooling type ice machine, including freeze slot, the slot outlet end of freezing passes through conduit and evaporator
The connection of refrigerating medium return pipe, evaporator bottom end refrigerating medium outlet pipe are connect by conduit with slot input end is frozen, evaporator top steam
Outlet end is connect by siphunculus with refrigeration compressor input end, refrigeration compressor outlet end pass through conduit respectively with condenser inlet
End, the connection of evaporator top steam inlet end, condensator outlet end are connected to the filter by conducting, and filter outlet end passes through
Conduit is connected to evaporator top steam inlet end, installs expansion valve on the conduit at filter outlet end.
Pressure controller is installed on the refrigeration compressor as a further solution of the present invention,.
It installs and follows on the conduit of the evaporator bottom end refrigerating medium outlet pipe as a further solution of the present invention,
Ring pump.
Compared with prior art, the utility model has the beneficial effects that the ice bank aluminium of the utility model direct-cooling type block ice machine
Inside plate hollow pipeline, originally be the liquid such as freon, ammonia, 407C or gaseous refrigerant, be converted into refrigerating medium and freeze
Mode.Because refrigerant be converted into refrigerating medium ice making after, direct-cooling type block ice machine ice-making system become structure be simple and convenient to operate,
High degree of automation and use are safe.On traditional direct-cooling type ice machine, the utility model is to change existing direct-cooling type ice making
The ice making mode of refrigerant is largely filled in machine ice bank aluminium sheet.And filling refrigerant is converted into filling refrigerating medium, reduces system
It makes and use cost, so that the design structure of ice machine becomes simply, the safety is improved, it is easy to accomplish automation control, refrigeration
The cryogenic temperature of unit can accomplish automation control, facilitate management, reduce cost.Design letter in the refrigeration unit part of ice machine
It is single, large capacity Refrigerant-storage vessel, pipeline and valve etc. are saved, ice bank section of tubing the inside fills refrigerating medium, design pressure
Become smaller, refrigerating medium selects Environment-friendlyfood-grade food-grade, be not afraid of leakage, as long as water pump can rapid circulating transfer heat, safety coefficient
It improves, refrigerating medium only recycles the approach for reducing refrigerating medium between evaporator, refrigeration compressor, condenser, reduces refrigerating medium
Use, efficiently solve the problems, such as direct-cooling type ice machine need it is at high cost.
Detailed description of the invention
Fig. 1 is that the indirect type of inexpensive direct-cooling type ice machine freezes scenario-frame schematic diagram.
In figure: 1, freezing slot, 2, evaporator, 3, refrigeration compressor, 4, condenser, 5, filter, 6, circulating pump, 7, pressure

Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Embodiment one: referring to Fig. 1, a kind of low cost direct-cooling type ice machine, including freeze slot 1, the aluminium sheet pipeline of ice bank
The environmentally friendly refrigerating medium of middle filling, pushes directly on that refrigerating medium circulates in ice bank aluminium sheet pipeline and heat exchanger exchanges heat with water pump
Amount is frozen 1 outlet end of slot and is connected to by conduit with 2 refrigerating medium return pipe of evaporator, and 2 bottom end refrigerating medium outlet pipe of evaporator passes through conduit
It is connect with 1 input end of slot is frozen, circulating pump 6 is installed on the conduit of 2 bottom end refrigerating medium outlet pipe of evaporator, will carried by circulating pump 6
