Detailed description of the invention
Based on embodiment, present invention is described below, but the present invention is not restricted to these embodiments.In hereafter details of the present invention being described, detailedly describe some specific detail sections.Do not have the description of these detail sections can understand the present invention completely for a person skilled in the art yet.In order to avoid obscuring essence of the present invention, known method, process, flow process, element do not describe in detail.
The embodiment of suction filter of the present invention is described referring to Fig. 1.
As shown in Figure 1, this suction filter comprises body and is arranged at intrinsic filter.Body is also provided with differential pressure controller 1, refrigerant pressure after refrigerant pressure before being filtered by differential pressure controller 1 detection and after filtration device are filtered also obtains front and back pressure reduction, when the pressure difference detected exceedes preset value, export cue, remind operating personnel to need more renew cartridge.First on suction filter without the need to reserved outside pressure tappings, secondly simplify the structure, do not need external Pressure gauge when debugging compressor bank, simple to operate, control accuracy is high.
Wherein, filter comprises filter core 2 and filter bag 3, and filter core 2 and filter bag 3 are all detachably arranged in body, and refrigerant filters through filter core 2 and filter bag 3 successively." interior " " outward " described is herein relative suction filter.Filter core 2 is preferably stainless steel filtering net.Set up filter bag 3 in the filter and first can improve filter effect, the impurity such as the iron filings avoiding some little be not filtered and directly the system of entering cause system dirty stifled, in addition, because filter bag 3 and body are for removably connecting, after repeatedly changing filter bag 3, the thoroughly impurity of clean whole freezer fluorine system, do not need again mobile filter core 2 simultaneously, simple to operate, it is convenient to change, and system clean degree also improves greatly.
Concrete, body comprises shell and is arranged at the first support member 4 and the second support member 5 in shell, and the two ends of filter core 2 and filter bag 3 support in the enclosure respectively by the first support member 4 and the second support member 5.Filter bag 3 is placed in filter core 2.Preferably, the first support member 4 and the second support member 5 are disk-like structure, and both middle parts are all protruded and are provided with boss 6, and the two ends of filter core 2 are inserted on two boss 6 respectively.The two ends of filter bag 3 are separately fixed on the first support member 4 and the second support member 5.One end of filter core 2 and filter bag 3 is closed by the first support member 4, and the other end of filter core 2 is also closed by the second support member 5, and it has the through hole 51 be communicated with the port of filter bag 3.
The space that first support member 4, second support member 5 and shell surround by filter core 2 and filter bag 3 is the first cavity 7, second cavity 8 and the 3rd cavity 9 by radial outside to internal separation.Shell offers import 101 and outlet 131.Refrigerant enters the first cavity 7 from import 101, after filter core 2 filters, enter the second cavity 8, enters the 3rd cavity 9, finally discharged by outlet 131 after filter bag 3 filters.Differential pressure controller 1 is communicated with the first cavity 7 through first passage 11, thus detects the refrigerant pressure before the first cavity 7 inner filtration, and differential pressure controller 1 is communicated with the 3rd cavity 9 through second channel 12, thus detects the refrigerant pressure after the 3rd cavity 9 inner filtration.
Further, shell comprises the housing 10 of both ends open, and the one end open near the second support member 5 is closed by end socket 13, and the one end open near the first support member 4 is closed by blind flange 15, and differential pressure controller 1 is fixedly installed on blind flange 15.Import 101 is arranged on housing 10, and outlet 131 is arranged on end socket 13.Housing 10 opening part is provided with end cap 14, blind flange 15 is fixed through securing member 16 and end cap 14, second support member 5 coordinates with the inner peripheral surface of end cap 14, holddown spring 17 is provided with between second support member 5 and blind flange 15, improved the installation reliability of blind flange 15 by holddown spring 17, prevent getting loose of securing member 16.
In said structure, the outer peripheral face of filter core 2, the second support member 5 surround the first cavity 7 near the end face of filter core 2, end cap 14 near the end face of filter core 2 and the inner peripheral surface of housing 10.The second cavity 8 is formed between filter core 2 and filter bag 3.The inner peripheral surface of filter bag 3 and the second support member 5 surround the 3rd cavity 9 away from the end face of filter core 2 and the inner surface of end socket 13.
First passage 11 is communicated with the first cavity 7 with end cap 14 through blind flange 15 successively.Second channel 12 is communicated with the 3rd cavity 9 through blind flange 15, holddown spring 17 and the second support member 5 successively.
For improving sealing, between the two ends of filter core 2 and the first support member 4 and the second support member 5, be provided with seal.Also seal is provided with between end cap 14 and blind flange 15.Seal is preferably sealing ring 18.
Preset value is prestored in differential pressure controller 1, when carrying out the debugging of compressor bank, differential pressure controller 1 detects the pressure of the first cavity 7 and the 3rd cavity 9 in real time and calculates pressure reduction, when pressure difference exceedes preset value, differential pressure controller 1 exports cue to master controller, prompting needs more renew cartridge, controls the frequency of more renew cartridge with this.
Because whole installation fluorine systematic pipeline is very long, and be subject to the impact of installation specification degree, there are a lot of impurity and mud in the inside, so when initiating switchup runs, need repeatedly to run replacing filter bag 3 and carry out cleaning systems, not so impurity enters into helical-lobe compressor, can cause compressor fault, may burn compressor time serious.When dismounting filter bag 3 and more renew cartridge 2, the parts such as securing member 16, blind flange 15, end cap 14, holddown spring 17, first support member 4, sealing ring 18 are needed to pull down successively, then old filter bag 3 is removed, replace with new filter bag 3, and then above part is installed successively, continue operating unit, after changing four to five filter bags 3, filter core 2 is also removed together, and the impurity outside filter core 2 is thoroughly cleaned out and after drying, is again encased in suction filter.During normal operation, filter core 2 is only stayed to use in suction filter.
