Description
Technical field
The utility model relates to a kind of refrigerating plant, particularly relates to a kind of for the refrigerating plant under mine.
Background technology
As shown in Figure 1, the operating principle of refrigeration unit is as follows: refrigeration host computer comprise compressor 1 ', condenser 2 ', motor 3 ' and control device 4 '.Compressor 1 ' and shell and tube evaporator 5 ' composition refrigeration and defeated cooling system, compressor 1 ' air inlet pipe and shell and tube evaporator 5 ' escape pipe be connected, compressor 1 ' escape pipe and condenser 2 ' be connected, condenser 2 ' escape pipe by choke valve and shell and tube evaporator 5 ' air inlet pipe be connected, adopt the R407C type cold-producing medium of safety and environmental protection, cold-producing medium shell and tube evaporator 5 ' in be subject to thermal evaporation to absorb heat, thereby by by shell and tube evaporator 5 ' hot water change cold water into, cold water by water pump be transported to air cooler 6 ', air cooler 6 ' in transfer heat to by air cooler 6 ' air, thereby can reach the object that makes work plane or heading end cooling.Condenser 2 ', shell and tube evaporator 5 ' and cooler 7 ' formation heat extraction and cooling system, the heat that cold-producing medium absorbs condenser 2 ' in pass to cooling water, cooling water interior heat amount (being high temperature water) discharge has two kinds of modes, and the one, open, high temperature water is by directly emptying; The 2nd, closed, high temperature water be sent to cooler 7 ', through shower water evaporation and the atmosphere absorbing and cooling temperature that flows through, the cold water after cooling is sent back to main frame and recycles.
Compressor in the refrigeration host computer using under mine is at present all piston type, screw or centrifugal compressor, these traditional compressor volumes are larger, and wherein non lubricant oil exists, and need to separately establish oil piping system, therefore whole main machine structure is comparatively complicated, causes system effectiveness low.Adopt the refrigeration host computer of traditional compressor generally need to be equipped with high-power, high-tension motor, noise and vibration are all larger, thereby also need to be equipped with damping accessory.In addition, when traditional refrigeration host computer starts, electric current is larger, also large to electrical network impact, and adopts centrifugal compressor also to have surge phenomenon.There is larger mechanical friction in traditional bearing of compressor, needs lubrication oil.And between the refrigeration host computer of using under existing mine and shell and tube evaporator, by pipe, be connected, two equipment are not set together, and will take larger space like this, and placement process waste time and energy.
Utility model content
The technical problems to be solved in the utility model is to provide the mining refrigeration host computer of cold water type that a kind of safety, volume are little, the life-span is long.
The utility model cold water type is mining refrigeration host computer, comprise casing, in described casing, be provided with compressor, condenser, choke valve, shell and tube evaporator and control device, described compressor is magnetic suspension compressor, it is fixed on condenser and includes a motor, the escape pipe of described magnetic suspension compressor is connected with condenser, and air inlet pipe is connected with the escape pipe of shell and tube evaporator, and the escape pipe of described condenser is connected with the air inlet pipe of shell and tube evaporator by choke valve.
The utility model cold water type is mining refrigeration host computer, the quantity of wherein said magnetic suspension compressor is two or more, the air inlet pipe that the connected mode of the air inlet pipe of magnetic suspension compressor and the escape pipe of shell and tube evaporator is every magnetic suspension compressor is all connected with a tube connector, and the other end of tube connector is connected with the escape pipe of shell and tube evaporator.
The utility model cold water type is mining refrigeration host computer, roof and the sidewall of wherein said casing are provided with hoisting ring.
Refrigeration host computer difference from prior art that the utility model cold water type is mining is that the compressor in the mining refrigeration host computer of the utility model cold water type is magnetic suspension compressor, because magnetic suspension compressor volume is little, take up room just little, with respect to the refrigeration host computer that adopts traditional compressor, its volume dwindles greatly, just can suitably increase on this basis the volume of condenser, increase the heat transfer area of condenser, thereby can improve the refrigerating capacity of separate unit main frame.Add shell and tube evaporator is integrated on refrigeration host computer, so just reduced taking up room of Set under a well widely, cost saving, mounting arrangements is convenient.Magnetic suspension compressor structural vibration, close to zero, does not need expensive damping accessory, does not exist unit vibration to damage the danger in tunnel.Magnetic suspension compressor adopts magnetic suspension bearing, and unit starting current only needs 2A just can make rotating shaft suspend, and starting torque is very little, thereby also just less to the impact of electrical network, thereby also just safer.There is not mechanical friction in the bearing of magnetic suspension compressor, thereby does not need lubrication oil, and the life-span is longer.
In the utility model cold water type is mining refrigeration host computer, roof and the sidewall of casing are provided with hoisting ring, so just can easily refrigeration host computer be transported under mine.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is refrigeration unit schematic diagram of refrigerating;
Fig. 2 is the structure chart of the mining refrigeration host computer of the utility model cold water type.
The specific embodiment
As shown in Figure 2, the utility model cold water type is mining, and refrigeration host computer comprises casing 1, in described casing 1, be provided with two compressors, condenser 3, choke valve (not shown), shell and tube evaporator 4 and control device 5, described compressor is magnetic suspension compressor 2, it is fixed on condenser 3 and includes a motor (not shown), the escape pipe 6 of every magnetic suspension compressor 2 is all connected with condenser 3, air inlet pipe 7 is all connected with a tube connector 8, the other end of tube connector 8 is connected with the escape pipe of shell and tube evaporator 4, the escape pipe of described condenser 3 is connected with the air inlet pipe of shell and tube evaporator 4 by choke valve.Four angles on casing 1 roof are respectively provided with a hoisting ring 9, lay respectively on the sidewall of 3 two ends of condenser and are all provided with two hoisting rings 9.
What adopt due to the utility model be magnetic suspension compressor 2, and it does not use lubrication oil, so the efficiency of unit improves greatly, cooling unit moves for a long time for applicable need of production, therefore energy saving comparison is obvious.Magnetic suspension compressor 2 operates steadily, and noise is less, is also conducive to Set under a well operational management personnel's health.
In the utility model, the quantity of magnetic suspension compressor 2 can increase and decrease according to the difference of refrigerating capacity.
Magnetic suspension bearing is a kind ofly utilize magnetic field and make rotor suspension, thereby can not produce when rotated Mechanical Contact, can not produce mechanical friction, no longer needs the necessary lubricating system of mechanical bearing and mechanical bearing.In refrigeration compressor, use magnetic suspension bearing, this kind of compressor is magnetic suspension compressor.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
