Fig. 2 is the top view of the utility model filter.
Specific embodiment
The utility model is described in detail below with reference to each implementation method shown in the drawings.But these implementation methods
The utility model is not intended to limit, in the structure or function that one of ordinary skill in the art is made according to these implementation methods
Conversion is all contained in protection domain of the present utility model.
As shown in Figure 1 to Figure 2, the utility model provides a kind of photovoltaic module lamination EVA filters 100, described
Filter 100 is arranged between vavuum pump and laminating machine, is used to filter the aerial EVA of dissolving.
The filter 100 include housing 10, be arranged in housing 10 gas channel, positioned at gas channel two ends with
It is respectively communicated with air inlet 20 and the gas outlet 30 of laminating machine and vavuum pump.
The filter 100 is additionally provided with demarcation strip 12, and the demarcation strip 12 is arranged at intervals at gas channel and is close to
At the position of gas port 30, it is used to stop that EVA is crystallized, wherein, the two neighboring demarcation strip 12 phase respectively from gas channel
To extending on inwall, and in being staggered.
The demarcation strip 12 includes the first demarcation strip 121 and the second demarcation strip that are fixed in the opposed inner walls of gas channel two
122, the demarcation strip 122 of first demarcation strip 121 and second is obliquely installed from gas channel inwall towards air-flow opposite direction, by
This can play a part of a stop to air-flow, thus may be such that EVA has the sufficient time to crystallize.
Some first demarcation strips 121 are arranged in parallel, and some second demarcation strips 122 are arranged in parallel.
The two neighboring demarcation strip 12 partly overlaps setting in the direction of the air flow, and thus, gas can only be in the first demarcation strip 121 and
It is looped through between two compartment plate 122, so that EVA has more fully crystallization time, demarcation strip 12 can also stop big absolutely
Partial crystallization, with preventing from EVA from continuing leaking out to vavuum pump.
As depicted in figs. 1 and 2, in the present embodiment, the housing 10 is cylindrical, and the air inlet 20 and goes out
Gas port 30 is located at the same side of the housing 10.So as to be additionally provided with division board 11, the division board in the inner side of the housing 10
11 extend between air inlet 20 and gas outlet 30, and gas channel are divided into the inlet channel 21 of connection air inlet 20, are connected
The outlet passageway 22 of pass-out gas port 30 and it is formed between the end of division board 11 and the inwall of housing 10 and connects inlet channel 21
With the communicating passage 23 of outlet passageway 22.Certainly, if the air inlet 20 and gas outlet 30 are arranged at the other positions of housing 10
Place, as long as gas channel can be formed, can reach the purpose of this utility model.In the present embodiment, the demarcation strip 12 exists
It is arranged at intervals on airflow direction in outlet passageway 22, by pumping fluid 40 in inlet channel 21 and communicating passage 23 to gas
Cooling, on the demarcation strip 12 that EVA crystallizations can fully depend in outlet passageway 22.
As shown in figure 1, the housing 10 is placed vertically, accordingly, the air inlet 20 and gas outlet 30 may be contained within institute
The upside of housing 10 is stated, therefore, the distribution vertically from top to bottom of the division board 11.Thus, the inlet channel 21 and outlet are logical
Road 22 is also distributed up and down, and gas passes through more smooth during air inlet, and gas is gradually ramped up during outlet, may be such that filtering is more abundant.When
So, if the housing 10 is otherwise placed, can reach the purpose of this utility model.
In the present embodiment, the housing 10 is placed vertically, while injection pumping fluid 40, institute in the housing 10
Stating pumping fluid 40 can cool down to the gas for entering, and can accelerate the condensation of EVA.Wherein, the liquid level of the pumping fluid 40
Highly it is the 1/3 to 2/3 of the height of the filter 100, it is preferred that the liquid level of the pumping fluid 40 is the filtering
The 1/3 of the height of device 100.In addition, in the present embodiment, as shown in Fig. 2 the housing 10 is in the cylindrical shape placed vertically,
The division board 11 is isolated along the diameter distribution of the cylinder with by inlet channel 21 and outlet passageway 22, certainly, if described
Housing 10 is in other shapes, and the division board 11 otherwise isolates inlet channel 21 and outlet passageway 22, also can reach this
The purpose of invention.
The filter 100 also includes air inlet pipe 2 and escaping pipe 3, the air inlet pipe 2 and escaping pipe 3 respectively with institute
State air inlet 20 and the sealing of gas outlet 30 coordinates, and be fixedly connected by flange, to facilitate the installation of air inlet pipe 2 and escaping pipe 3
And disassembly, cleaning.The porch of the air inlet pipe 2 is provided with screen pack（It is not shown）, first can be carried out to the gas in laminating machine
Secondary filtering, and may filter that a part of bulky grain.The air inlet pipe 2 and escaping pipe 3 are respectively logical to inlet channel 21 and outlet
Extend in road 22, also, the air inlet pipe 2 submerge the pumping fluid 40 liquid level under, thus, enter in the air inlet pipe 2
Gas can more preferably pass through pumping fluid 40, and carry out abundant and quick heat exchange with pumping fluid 40.Accordingly, it is described every
Also extended downwardly in the housing 10 from plate 11, and under the liquid level of the pumping fluid 40 that must also submerge, and, it is preferred that it is described every
From plate 11 extend downwardly with a distance from exceed the air inlet pipe 2 extended distance.In present embodiment, the air inlet pipe 2 and outlet
Pipe 3 is vacuum tube.
Therefore, the gas for carrying EVA passes through air inlet pipe 2, the filter screen filtration of the porch of air inlet pipe 2 one from laminating machine
Divide larger particle, and enter in the pumping fluid 40 of filter bottom by air inlet pipe 2.Pumping fluid 40 drops to gas
Temperature is so that EVA gas condensations are into crystallization, and enter outlet passageway 22 through communicating passage 23.It is provided with outlet passageway 22 some
Demarcation strip 12, demarcation strip 12 stops that air-flow passes through, and causes that the crystallization of EVA gases is condensed on demarcation strip 12, so that, obtain net
During the gas of change delivers to vavuum pump from escaping pipe 3, abrasions and corrosion of the EVA to vavuum pump are prevented.
It should be understood that, although the present specification is described in terms of embodiments, but not each implementation method only includes one
Individual independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art will should say
Used as an entirety, technical scheme in each implementation method can also be through appropriately combined, and forming those skilled in the art can for bright book
With the other embodiment for understanding.
The a series of tool described in detail only for feasibility implementation method of the present utility model of those listed above
Body illustrates that they are simultaneously not used to limit protection domain of the present utility model, all to be made without departing from the utility model skill spirit
