Description

Technical Field

[0001] The utility model relates to the technical field of dust removal of color sorters, in particular to a blowing structure for a blanking dust removal device. Background Art

[0002] A color sorter is a device that automatically sorts out different-colored particles in granular materials based on the differences in the optical properties of the materials. During the operation of the color sorter, the selected materials mixed with dust and impurities pass through the feeding device and the chute to reach the sorting area, raising a large amount of dust. The front glass of the sorting chamber will be quickly contaminated, affecting the sorting effect.

[0003] The existing color sorters are equipped with dust removal devices. The blowing component, driven by a fan, raises the sundries in the materials, and the air extraction component sucks the raised sundries to the external environment of the color sorter, thus preventing excessive sundries from entering the color sorting device and affecting the sorting effect.

[0004] There is a phenomenon that the air volume distribution in each channel of the blowing structure of the existing dust removal device is uneven, resulting in an unsatisfactory dust removal effect. Summary of the Utility Model

[0005] To solve the technical problem that the blowing mechanism of the existing dust removal device has uneven air volume, the utility model provides a blowing structure for a blanking dust removal device, including:

[0006] A centrifugal fan, and an air blowing cylinder is provided at the air outlet of the centrifugal fan for air outlet;

[0007] The air blowing cylinder includes a flange plate, an upper plate, a rear end air guiding plate, a connecting plate, a lower plate, a front end air guiding plate and an air outlet. The flange plate is connected to the air outlet of the centrifugal fan, the connecting plate is connected to the flange plate to form the front end transition of the air blowing cylinder. One end of the front end air guiding plate is connected to the flange plate. The front end air guiding plate is in an arc structure. The upper plate and the lower plate are spliced to form the air blowing cylinder, and a plurality of air outlets are equidistantly arranged at the intersection of the inclined surfaces of the two, forming a plurality of independent air blowing ports. One end of the upper plate is fixed to the flange plate and the connecting plate, and the other end of the upper plate is connected to the rear end air guiding plate. One end of the lower plate is fixed to the flange plate and the front end air guiding plate, and the other end of the lower plate is fixed to the rear end air guiding plate. The rear end air guiding plate is in an arc structure.

[0008] By the above technical solution, setting the front end air guiding plate as an arc structure can make the air inlet smooth.

[0009] Setting the rear end air guiding plate as an arc structure can reduce the swirling and accumulation of the rear end air flow.

[0010] Aligning the angle of the air outlet with the blanking port and the air extraction port can quickly raise and blow away the light impurities and dust, and can ensure the efficiency during dust removal to the greatest extent.

[0011] As a further improvement of the above solution, the lower plate forms an angle α with the horizontal plane, the upper plate forms an angle β with the horizontal plane, and the size between α and β is the size of the air outlet.

[0012] Through the above technical solution, setting the angle between the lower plate and the horizontal plane as α can ensure that it is consistent with the inclination angle of the discharge chute of the color sorter equipment, making the blowing direction directly face the suction port of the chute, which is convenient for sucking away dust and impurities.

[0013] Setting the angle between the upper plate and the horizontal plane as β is convenient for reducing the accumulation of dust, impurities and materials on the upper plate.

[0014] As a further improvement of the above solution, the whole air blowing cylinder forms an angle γ from the front end to the rear end.

[0015] Through the above technical solution, the set angle γ makes the volume of the air blowing cylinder gradually decrease, and can better balance the air output of each air outlet.

[0016] As a further improvement of the above solution, a sliding mechanism is further provided under the centrifugal fan and the air blowing cylinder. The sliding mechanism includes an adjusting plate, a slide rail, a slot, a pull plate, a connecting frame and a clamping unit. A slot is opened in the adjusting plate, the slide rail is penetrated and opened on the adjusting plate and communicated with the slot. One end of the connecting frame is fixed on the centrifugal fan and the air blowing cylinder through bolts, and the other end of the connecting frame is movably located in the slide rail through the clamping unit, and the pull plate is movably arranged in the slot.

[0017] Through the above technical solution, the adjusting plate is fixed on one side of the chute of the color sorter by using bolts. When adjusting the positions of the centrifugal fan and the air blowing cylinder, just push directly. The adjustment function can be quickly completed. Combined with the wind speed of the centrifugal fan, the appropriate wind speed can be adjusted according to the quality of different materials, and the dust removal operation can be better carried out.

[0018] At the same time, a magnet one is arranged at one end of the pull plate, and a magnet two is arranged in the slot. The magnet one and the magnet two adsorb each other, so that the pull plate is stably located in the slot.

[0019] As a further improvement of the above solution, the clamping unit includes an activity groove, an insertion block, a spring one, a pressing block, a spring two, a receiving groove one and a receiving groove two. The two activity grooves are symmetrically penetrated and opened on the connecting frame. The insertion block can be movably located in the activity groove. One end of the insertion block is connected with the spring one and contacts the pressing block, and the other end of the insertion block contacts the inner wall of the slide rail. One end of the spring two is fixed to the pressing block, and the other end of the spring two is fixed in the connecting frame. The two receiving grooves one are opened on the pressing block, and the receiving groove two is opened on the pull plate beside the pressing block.

[0020] Through the above technical solution, barbs are provided on one side of the insertion block close to the slide rail, and a rubber pad is provided on the inner wall of the slide rail. When the extrusion block squeezes the two insertion blocks into the slide rail, the barbs are inserted into the rubber pad, which can increase the friction between the insertion block and the slide rail, thereby ensuring that the hair dryer can stably perform the air outlet operation.

[0021] Meanwhile, under the action of the first receiving groove and the second receiving groove, when the insertion block and the extrusion block enter, the barbs are away from the rubber pad, so that the position of the connecting frame can be smoothly adjusted and can slide smoothly in the slide rail.

[0022] As a further improvement of the above solution, mounting plates are symmetrically arranged on the connecting frame, and a plurality of balls roll on the mounting plates, and all the balls are in contact with the adjusting plate.

[0023] Through the above technical solution, through a plurality of balls, it can be ensured that when adjusting the positions of the centrifugal fan and the hair dryer, the balls slide stably on the adjusting plate. On the one hand, the friction is reduced, and on the other hand, the movement is smoother.

[0024] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0025] By setting the hair dryer in a special shape, the present utility model can ensure that the air volume blown out by each channel is balanced during blowing, and the air outlet is smooth, effectively ensuring the overall dust removal effect. And under the action of the sliding mechanism, it is more convenient to adjust the distance between the hair dryer and the feeding and discharging ports of the color sorter, ensuring better adaptability of the color sorter to various materials and improving the working efficiency.

[0046] Working principle:

[0047] When performing the screening operation, first, according to the different materials to be screened, the distance between the air outlet 207 and the chute on the color sorting device is adjusted. During the adjustment, first pull the pulling plate 8 out of the slot 7, so that the first magnet installed on one side of the pulling plate 8 and the second magnet in the slot 7 are separated from each other, and the receiving slot 17 moves with the pulling plate 8 and gradually approaches the pressing block 13. When the pressing block 13 reaches the receiving slot 17, under the rebound of the second spring 14, the pressing block 13 is squeezed into the receiving slot 17. The receiving slot 15 is located on one side of the plug 11. Under the rebound of the first spring 12, the two plugs 11 are driven to move into the receiving slot 15, so that the two plugs 11 are away from the inner wall of the slide rail 6, and then the centrifugal fan 1 and the blowing cylinder 2 are pushed to slide along the slide rail 6, and a plurality of balls 16 roll on the adjusting plate 5 to adjust the distance between the blowing cylinder 2 and the chute.

[0048] When the distance between the two is adjusted, then insert the pulling plate 8 into the slot 7 again, so that the first magnet and the second magnet are adsorbed to each other. During this process, the pressing block 13 moves away from the receiving slot 17, the pulling plate 8 squeezes the pressing block 13 into the connecting frame 9, compresses the second spring 14, and the two receiving slots 15 are away from the plug 11. The pressing block 13 can push the two plugs 11 out of the activity slot 10 and contact the inner wall of the slide rail 6, and then the adjustment operation can be completed.

[0049] During operation, start the centrifugal fan 1 so that the air generated by the centrifugal fan 1 enters the blowing cylinder 2, and the air flows out from multiple air outlets 207 and blows to the chute air suction port of the color sorter equipment, facilitating the suction of dust and impurities.

[0050] The above embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby.
