Abstract
The utility model discloses an updraft ventilator of dry -off oven, including main tuber pipe way, main tuber pipe way is connected with two straight tubes of airing exhaust, a suction opening has been opened respectively to the lower part both sides of dry -off oven, two straight tubes of airing exhaust are connected respectively on two suction openings of dry -off oven lower part. The utility model discloses take to set up the suction opening in the lower part and carry out convulsions, changed the inside gas circulation mode of dry -off oven, can the condensation in the time of can avoiding hot oil gas in the dry -off oven to rise to the dry -off oven roof become little oil and drip, thereby and drip also can not drip at the oil that lower part suction opening department produced and form the oil stains on being caused the battery piece on the battery piece of drying and influence battery piece life, the aluminium foil wired hose that turns over in one's mind in the adoption replaces partial stainless steel branch pipe, and can conveniently dismantle to change does not just influence device structure to can reduce the cost.
Description
Technical field
The utility model relates to a kind of extractor fan of drying oven.
Background technology
Since entering 21 century, photovoltaic generation, as desirable renewable energy power generation technology, obtains fast development.Under the pulling in market, form the production capacity of 1200MW to China in 2006.In the whole technological process of production of solar cell piece, need to dry cell piece, baking operation all carries out in drying oven, need that exhausting is carried out to drying oven at drying course and the oil gas produced in drying oven inside is discharged to outside, as shown in Figure 1, traditional drying oven extractor fan is by suspended hood 2, air draft straight tube 3, main air duct forms, described suspended hood 2 is arranged on the exit of drying oven 1 end face one suction opeing, the upper end of described suspended hood 2 is connected with the lower end of air draft straight tube 3, the upper end of described air draft straight tube 3 is connected with main air duct, described air draft straight tube 3 is also provided with volume damper 4.Traditional extractor fan is discharged by the deep fat gas in drying oven by top air draught mode, but the deep fat gas in drying oven can be condensed into little oil droplet when rising to drying oven top board, can drip in pollution drying oven 1 when gathering little oil droplet to a certain extent the cell piece be placed on pallet, thus cause on cell piece and form oil mark, and the dregs of fat that oil droplet produces have a strong impact on cell piece service life.
Utility model content
The purpose of this utility model is the extractor fan providing a kind of drying oven, this device can change the gas circulating of drying oven inside, little oil droplet can be condensed into, the effective problem solving condensation oil dripping on drying oven top board when the deep fat gas in drying oven can be avoided to rise to drying oven top board.
Solve the problems of the technologies described above, the utility model takes following technical scheme to be achieved:
A kind of extractor fan of drying oven, comprise main air duct, it is characterized in that: described main air duct is connected with two air draft straight tubes, the both sides, bottom of described drying oven have a suction opeing, and described two air draft straight tubes are connected on two suction opeings of drying oven bottom.
Improve as the utility model one, described two air draft straight tubes are connected on two suction opeings of drying oven bottom respectively by an elbow.
Preferably, described air draft straight tube is stainless steel arm, aluminium foil wired hose of turning in one's mind in being connected with between described air draft straight tube and elbow.
Further, aluminium foil wired hose of turning in one's mind in described is connected with air draft straight tube with described elbow by flange.To turn in one's mind in employing aluminium foil wired hose dismounting and change easy to connect, and do not affect maintenance of equipment.
As further improvement of the utility model, described air draft straight tube is also provided with volume damper, for regulating the size of exhausting.
Compared with prior art, the utility model has following beneficial effect:
The utility model is taked to arrange suction opeing in bottom and is carried out exhausting, change the gas circulating of drying oven inside, can be condensed into little oil droplet when the deep fat gas in drying oven can be avoided to rise to drying oven top board, and the oil droplet produced at downdraft mouth place also can not drop onto the cell piece of drying is caused and cell piece forms oil mark and affects cell piece service life; Aluminium foil wired hose of turning in one's mind in employing replaces part stainless steel arm, can replacing for convenience detach and do not affect maintenance of equipment, and can reduce cost.
Accompanying drawing explanation
Fig. 1 is the front view of prior art extractor fan;
Fig. 2 is the front view of the utility model embodiment one;
Fig. 3 is the front view of the utility model embodiment two.
In figure: 1-drying oven, 2-suspended hood, 3-air draft straight tube, 4-volume damper, 5-elbow, aluminium foil wired hose of turning in one's mind in 6-.
Detailed description of the invention
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
The extractor fan of drying oven is as shown in Figure 2 embodiment one of the present utility model, it comprises main air duct, two air draft straight tubes 3 are connected with in the lower end of described main air duct, described air draft straight tube 3 is stainless steel arm, the both sides, bottom of drying oven 1 have two suction opeings, and two air draft straight tubes 3 are connected on two suction opeings of drying oven 1 bottom respectively by an elbow 5; Air draft straight tube 3 is also provided with volume damper 4, for regulating the size of exhausting.
When reality uses, the end face of described drying oven also has opening, this extractor fan is connected directly between the suction opeing place of drying oven bottom and carries out exhausting, thus form the exhausting mode of top air intake downdraft, circulating current is from top to bottom formed in drying oven inside, oil gas in drying oven is all walked downward, and then avoids oil gas to drop onto on cell piece at drying oven inner top formation condensation oil droplet.
The extractor fan of drying oven is as shown in Figure 3 embodiment two of the present utility model, itself and embodiment one unlike, to turn in one's mind in being connected with between described air draft straight tube 3 and elbow 5 aluminium foil wired hose 6, aluminium foil wired hose 6 of turning in one's mind in described is connected with air draft straight tube 3 with described elbow 5 by flange, to turn in one's mind in employing aluminium foil wired hose dismounting and change easy to connect, and do not affect maintenance of equipment.
The above embodiment only have expressed some embodiments of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
