Abstract
The utility model relates to a magnetic filter device for a large-sized refrigeration device. The magnetic filter device for the large-sized refrigeration device comprises a cylindrical shell, wherein welding openings are fixedly connected to the two ends of the shell respectively, a filter screen is installed in an inner cavity of the shell, an annular magnet is fixedly connected with the outer side of the circumferential surface of the shell, and a tapered opening is formed between the filter screen and the shell. According to the use principle of the magnetic filter device for the large-sized refrigeration device, impurities such as scrap iron are generated by the large-sized refrigeration device in the process of operation due to abrasion, when the impurities flow into the shell along with refrigerants, metal impurities with the large grain size are filtered through the filter screen arranged in the shell, and are intercepted to be located in the filter screen, and metal impurities with the small grain size pass through the filter screen, and are attracted to the inner wall of the shell through magnetic force. The magnetic filter device for the large-sized refrigeration device has the advantages that when the magnetic filter device for the large-sized refrigeration device is used, the phenomenon that components are replaced due to the fact that the broken scrap iron causes blocking in the components such as an oil separator, an expansion valve and a vapor-and-liquid separator is avoided, the maintenance cost is reduced, and the failure rate of the large-sized refrigeration device is effectively reduced.
Description
Technical field
The utility model relates to a kind of magnetic filter device, refers in particular to, and is applied to the magnetic filter device of all kinds of large-scale refrigeration plants.
Background technology
At present, in the running of the large-scale refrigeration plants such as great Jin VRV, freeze drier, often there is the damage of the parts such as gas-liquid separator, magnetic valve, expansion valve.Research by analysis, this thing happens, and a big chunk reason is the compressor internal components impurity such as some bushel iron bits that produce because of wearing and tearing in service, these impurity are along with cold-producing medium has been blocked in various parts when turning round in system, cause whole equipment to break down, and these parts will be changed, just need a no small expense.Therefore, design a kind of magnetic filter and remove scrap iron removing and various impurity, the fault rate that reduces equipment is imperative.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of magnetic filter device that is applied to large-scale refrigeration plant, can remove in time the iron filings impurity that equipment is in service produced.
The technical scheme that the utility model addresses the above problem is as follows:
A magnetic filter device that is applied to large-scale refrigeration plant, is characterized in that:
Comprise cylinder blanket, the affixed soldering opening in two ends of described shell, the inner chamber of shell is provided with screen pack, affixed annular magnet outside the side face of shell.
Further, between described screen pack and shell, form bell.
As preferably, the diameter of described shell is 50mm, and length is 100mm.
As preferably, the thickness of described magnet is 10mm.
Use principle of the present utility model is, the impurity such as iron filings that equipment produces because of wearing and tearing in running, when it flows into shell with cold-producing medium, the metal impurities that particle diameter is large, be arranged on screen pack in shell and filter, interception is in screen pack, and the metal impurities that particle diameter is little pass through screen pack, due to the effect of magnetic force, be adsorbed on the inwall of shell.
Compared with prior art, the beneficial effects of the utility model are:
1, by using the utility model, can by the impurity absorption such as bushel iron bits of taking out of in compressor on display pipe wall, make it can not be blocked in the positions such as oil eliminator, expansion valve, vapour liquid separator, cause equipment fault effectively to reduce equipment failure rate.
2, use the utility model, avoided because of the obstruction of bushel iron bits in the parts such as oil eliminator, expansion valve, vapour liquid separator, and the part replacement of bringing has been saved maintenance cost.
3, the utility model highly versatile, can be applied in all kinds of large-scale refrigeration plants.
4, the utility model is simple in structure, easy to process, and cost is lower, suitable popularization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 11 is soldering opening; 12 is magnet; 13 is shell; 14 is screen pack; 15 is bell.
Fig. 2 is that the utility model is applied in the fundamental diagram in freeze drying machine cooling system.
In figure: 1 is compressor; 2 is magnetic filter; 3 is oil eliminator; 4 is gas-liquid separator; 5 is hot by-passing valve; 6 is condenser; 7 is filter; 8 is magnetic valve; 9 is expansion valve; 10 is evaporimeter.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model and embodiment are described in further detail.
In conjunction with Fig. 1, a kind of magnetic filter device that is applied to large-scale refrigeration plant, comprises cylinder blanket 13, the affixed soldering opening 11 in two ends of described shell, and the inner chamber of shell is provided with screen pack 14, affixed annular magnet 12 outside the side face of shell.
Further, between described screen pack and shell, form bell 15.This structure is convenient to the large iron filings impurity of particle diameter to tackle on screen pack.
As preferably, the diameter of described shell is 50mm, and length is 100mm.
As preferably, the thickness of described magnet is 10mm.
Embodiment
As shown in Figure 2, cold-producing medium becomes high temperature and high pressure gas through compressor 1 acting, through the utility model magnetic filter 2, filter out impurity, arrive oil eliminator 3, the refrigerator oil that cold-producing medium is taken in oil eliminator work out of is separated and is got back to compressor 1, cold-producing medium arrives condenser 6 from oil eliminator out, through condensation, dispel the heat, refrigerant temperature is reduced, pass through successively again filter 7, magnetic valve 8, expansion valve 9, refrigerant pressure is reduced, then enter evaporimeter 10, evaporation endothermic, cold-producing medium becomes the state of gas-liquid mixed, through gas-liquid separator 4, the refrigeration of last gaseous state comes back to compressor.
Freeze drier uses through long-term, compressor is because inner body wearing and tearing can produce some bushel iron bits, use the utility model, can effectively these bushel iron bits be adsorbed on the tube wall of filter, make it can not enter internal system, cause the damage of oil eliminator, magnetic valve, these parts of gas-liquid separator, greatly reduce equipment failure rate, saved maintenance cost.
