Fig. 1 is the structural representation of embodiment dust collector;
Fig. 2 is that A-A of Fig. 1 is to structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.Bucket wheel machine trailer hopper blanking dust collector as shown in Figure 1 and Figure 2, belt conveyer is positioned at the below of trailer hopper 1, and the discharging opening below of trailer hopper 1 has the blanking baffle of pressure 8 being connected with hopper 1.Deflector chute support 13 is erected at the both sides of belt conveyer frame, described deflector chute support 13 is concave shape, the carrying roller 14 of belt conveyer is connected to the bottom at deflector chute support 13 centers, slide plate 12 is fixed on deflector chute support 13, be positioned at the both sides of carrying roller 14, slide plate 12 is wear-resistant slide plate, and load-transfer device 11 is supported jointly by carrying roller and slide plate 12.The side cover plate 9 of both sides is connected on deflector chute support 13, top blind flange 7 is connected with the upper end of described side cover plate 9, dustproof skirtboard 10 is positioned at the top of described load-transfer device 11, dustproof skirtboard 10 is fixedly connected in top blind flange 7, dustproof skirtboard clamps belt and slide plate, prevent belt deviation, also can stop dust to leak.The load-transfer device 11 of described top blind flange 7, side cover plate 9, slide plate 12, belt conveyer forms closed cross-section section, the two ends of closed cross-section section are respectively provided with the dustproof check apron 3 in an end, form closed box 2, in closed box 3, also have the dustproof check apron of multiple tracks with together with trapezoidal gyrotron 5, the below of described trapezoidal gyrotron 5 is connected with dustproof check apron.The discharging opening of trailer hopper 1 is communicated with the top of described closed box 2, the lower interface of counter flow pipe 4 is communicated with the top of described closed box 2, downward-sloping 45 ° of the top airduct of counter flow pipe 4 is communicated with described trailer hopper 1, duct cyclone 6 be positioned at described counter flow pipe 4 away from hopper direction, the ventilation inlet of duct cyclone 6 is communicated with the top of described closed box 2.
Enforcement principle of the present utility model and process are as follows:
Material falls through trailer hopper 1, falls on the load-transfer device 11 of belt conveyer, then carries out conveyor stacker through load-transfer device 11.Material, in falling process, produces negative-pressure air-flow, while falling on load-transfer device 11, impacts with belt, makes blanking place produce large stroke dust air, produces malleation.So just there is positive and negative pressure.Dust air-flow enters hopper by closed box by counter flow pipe, dust separates in counter flow pipe 4 with air, dust is through inhibition, alleviation, shock and depleted of energy drops on load-transfer device 11, air is back to trailer hopper 1, discharging point pressure decreased like this, trailer hopper pressure increases, and discharging point and trailer hopper positive and negative pressure are tended to balance, and has greatly reduced airborne dust.Downward-sloping 45 ° of counter flow pipe 4 top airducts are communicated with described trailer hopper 1, can prevent that blanking from entering counter flow pipe.Closed box 2 is provided with the dustproof check apron of multiple tracks and trapezoidal gyrotron 5, and dust air impact is prevented dust check apron and is blocked, and remaining dust air fully discharges, cushions, collides in trapezoidal gyrotron 5, and straight-line motion becomes curvilinear motion, plays the effect of slow Trimetaphan.Due to the processing layer by layer through counter flow pipe 4, trapezoidal gyrotron 5, dustproof check apron, the processing dust amount of air of duct cyclone 6 is very little, can reduce consumption of current, reduce production costs.
In other embodiments, hopper blanking dust collector can be used for combination bucket-wheel stacker reclaimer, arm-type stocker, bulk goods grab bucket ship unloader etc. and has the equipment of blanking hopper.Can solve same technical matters, and obtain identical or close technique effect.
Obviously, the utility model is not limited to above preferred implementation, also can be in the spirit of the utility model claim and specification sheets restriction, carry out conversion and the improvement of various ways, can solve same technical matters, and obtain the technique effect of expection, therefore do not repeat.Those of ordinary skill in the art can be from the disclosed content of the utility model directly or all schemes of associating, as long as within the spirit limiting in claim, also belong to protection domain of the present utility model.
