[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0029] See also Figure 1 - Figure 7 The present invention provides a ore bin feeding device, comprising a wooden type chute pipe 11 and a sulfur dioxide purification box 12 detachably mounted on both side surfaces of the wooden type chute pipe 11, ore materials 14 slidingly stacked on the inner wall surface of the wooden type chute pipe 11, and a lap transport platform 13 arranged at the edge positions on both sides of the outlet of the wooden type chute pipe 11, a supporting differentiation head 111 is arranged on the inner wall surface of the wooden type chute pipe 11 and located at the middle position, and a swing plate 112 movably fitted to the inner wall surface of the wooden type chute pipe 11 is swingably connected at the edge positions on both sides of the top of the supporting differentiation head 111, and a hydraulic rod 113 movably overlapped on the bottom surface of the swing plate 112 is fixedly mounted on both side surfaces of the wooden type chute pipe 11 and located at the bottom edge position of the swing plate 112, and a lap sealing strip 1110 movably overlapped on one side surface of the swing plate 112 is fixedly connected to the inner wall surfaces of the wooden type chute pipe 11;

[0030] Cooperate with the wooden chute pipe 11 to guide the ore material 14, and cooperate with the support differentiation head 111 on the inner wall of the wooden chute pipe 11 to differentiate the falling ore material 14 into two parts. When it is necessary to feed a series of coke bins, cooperate with the hydraulic rod 113 on the left side of the support differentiation head 111 to extend and then lift and push the swing plate 112 on the left surface of the support differentiation head 111, so that one side surface of the swing plate 112 is squeezed and fitted on the left inner wall of the wooden chute pipe 11, and cooperate with the overlapping sealing strip 1110 on the inner wall of the wooden chute pipe 11 to seal the fit between the swing plate 112 and the wooden chute pipe 11. As the ore material 14 is continuously moved on the left swing plate The ore material 14 is accumulated on the surface of the swing plate 112, and the excess ore material 14 flows toward the other side of the support differentiation head 111, so that the ore material 14 is accumulated on the surface of the swing plate 112 by the obstruction of the swing plate 112. As the height of the ore material 14 continues to increase, the excess ore material 14 is diverted to the other side, so that the feeding barrel can perform segmented feeding processing on the first and third series of coke bins without stopping feeding. It avoids the situation that when the traditional feeding bin needs to feed another channel during feeding, the feeding device needs to be stopped and the feeding channel needs to be changed. The whole process requires the equipment to be stopped. Multiple stops will reduce equipment performance and increase maintenance costs.

[0031] Furthermore, if Figure 1 - Figure 3 and Figure 5 - Figure 7As shown, the inner wall of the sulfur dioxide purification box 12 is fixedly connected to a ventilation pipe 121 at the entrance, a guide chute 122 is arranged on the inner wall of the bottom of the sulfur dioxide purification box 12, and the bottom end surface of the ventilation pipe 121 is arranged at the upper edge of the guide chute 122. The outer surface of the sulfur dioxide purification box 12 is provided with a closed door 123 located at the lower edge of the guide chute 122, and the inner wall of the ventilation pipe 121 is provided at the guide chute 122. A filter sponge plate 124 is fixedly connected to the top edge of the chute 122, and the outer surface of the filter sponge plate 124 is wrapped around the outer surface of the guide chute 122. A large-pore mesh plate 125 and a small-pore mesh plate 126 are fixedly connected to the inner middle wall of the sulfur dioxide purification box 12 and located at the top edge of the filter sponge plate 124, and the outer surfaces of the large-pore mesh plate 125 and the small-pore mesh plate 126 are wrapped around the outer surface of the air vent 121. The sulfur dioxide purification box 12 An EVA waterproof plate 127 wrapped on the outer surface of the air permeable tube 121 is fixedly connected to the inner top wall surface, an air hole 128 is provided on the outer surface of the sulfur dioxide purification box 12 and at the top edge position, a support frame 131 is symmetrically fixedly connected to the two side surfaces of the overlapping transport platform 13, a transmission roller 132 is provided on the outer surface of one end of the support frame 131, and a conveying crawler 133 wrapped on the outer surface of the overlapping transport platform 13 is movably connected to the outer surface of the transmission roller 132. A motor 134 is fixedly installed on the top outer surface of the overlapping transport platform 13 and at the edge positions on both sides, and a transmission roller 135 is fixedly connected to the output end of the motor 134. An auxiliary limiting rod 136 is movably connected to the inner wall surface of the bottom of the overlapping transport platform 13, and a rubber track 137 is movably connected to the outer surfaces of the transmission roller 135 and the auxiliary limiting rod 136, and the outer surface of the rubber track 137 is movably fitted to the top inner wall surface of the conveying crawler 133.

[0032] With the continuous diversion of the gas, the gas will enter the interior of the sulfur dioxide purification box 12, and cooperate with the air permeable pipe 121 on the inner wall of the sulfur dioxide purification box 12 to guide the sulfur dioxide into the depth of the sulfur dioxide purification box 12. As the bubbles continue to float up and down, cooperate with the filter sponge plate 124 to differentiate the large air mass into small air masses, and at the same time, some too fine impurity particles are filtered out. At the same time, under the guidance of the diversion chute 122, the particulate dust is accumulated in the interior of the sulfur dioxide purification box 12. As the bubbles continue to rise, the large-pore mesh plate 125 and the small-pore mesh plate 126 are continuously differentiated to continuously split and refine the bubbles, so as to achieve the purpose of utilizing the bubble group to enter the liquid. It floats freely, and cooperates with the large-pore mesh plate 125 and the small-pore mesh plate 126 to gradually differentiate the bubble clusters into small bubble clusters, thereby increasing the contact area and contact range with the alkaline liquid, so that the split and refined exhaust gas can fully contact with the alkaline solution inside the sulfur dioxide purification box 12, so that the sulfur dioxide can be fully purified. This avoids the problem that in traditional purification devices, when infusing bubble clusters, the gas inside the bubble clusters accumulates relatively large, and the bubble clusters cannot be differentiated and broken, resulting in the gas inside the bubble clusters being unable to fully contact with the external alkaline purification liquid, which can easily lead to insufficient purification of sulfur dioxide and residual sulfur dioxide.

[0033] Furthermore, if Figure 1 - Figure 4 As shown, the inner wall surface of the support differentiation head 111 and the bottom edge position of the hydraulic rod 113 are provided with a ventilation cavity 114 connected to the outer surface of the wooden type chute pipe 11, and the outlet of the ventilation cavity 114 is arranged at the edge position of the entrance of the sulfur dioxide purification box 12, and the inner wall surface of the ventilation cavity 114 and the connection position of the support differentiation head 111 and the wooden type chute pipe 11 are detachably installed with a blower 115, and the inner wall surface of the wooden type chute pipe 11 and the connection position of the wooden type chute pipe 11 are provided. A speed reduction baffle 116 is swingably connected to the edge position of the bottom entrance of the ventilation chamber 114, a hydraulic rod 117 is symmetrically fixedly installed on the inner wall of the wooden chute pipe 11 and at the bottom edge position of the speed reduction baffle 116, a rubber lining 118 is fixedly connected to the bottom wall of the wooden chute pipe 11 and at the outlet, a filter screen plate 119 is provided at the entrance of the ventilation chamber 114, and the ore 14 is accumulated on the top surfaces of the swing plate 112 and the speed reduction baffle 116.

[0034] When passing the material, the blower 115 is cooperated to absorb the gas inside the ventilation chamber 114, and then the air inside the wooden chute pipe 11 is absorbed into the ventilation chamber 114, and the gas around the top inlet and the bottom outlet of the wooden chute pipe 11 is absorbed into the interior of the wooden chute pipe 11 while inhaling. When the gas flows, the dust particles around the inlet and outlet of the wooden chute pipe 11 are absorbed into the interior of the wooden chute pipe 11. With the flow of airflow, the sulfur dioxide and nitrogen oxides in the air are absorbed into the ventilation chamber 114. When the gas enters the ventilation chamber 114, the filter plate 119 is cooperated to filter out some particulate dust inside the gas.

[0035] Working principle: cooperate with the wooden chute pipe 11 to guide the ore material 14, and cooperate with the support differentiation head 111 on the inner wall of the wooden chute pipe 11 to differentiate the falling ore material 14 into two parts. When it is necessary to feed a series of coke bins, cooperate with the hydraulic rod 113 on the left side of the support differentiation head 111 to extend and then lift and push the swing plate 112 on the left surface of the support differentiation head 111, so that one side surface of the swing plate 112 is pressed and fitted on the left inner wall of the wooden chute pipe 11. As the ore material 14 is continuously accumulated on the surface of the left swing plate 112, the excess ore material 14 will move toward the support The ore 14 is supported to flow in the other side of the splitting head 111, and the ore 14 is accumulated on the surface of the swinging plate 112 by the obstruction of the swinging plate 112. As the height of the ore 14 increases, the excess ore 14 is diverted to the other side, so that the feeding tube can feed the first and third series of coke bins in stages without stopping the feeding. When passing the material, the blower 115 is used to absorb the gas inside the ventilation cavity 114, and then the air inside the wooden chute pipe 11 is absorbed into the ventilation cavity 114, and the top entrance of the wooden chute pipe 11 is sucked while the air is sucked. The gas around the bottom outlet is absorbed into the interior of the wooden chute pipe 11. When the gas flows, the dust particles around the inlet and outlet of the wooden chute pipe 11 are absorbed into the interior of the wooden chute pipe 11. With the flow of the airflow, the sulfur dioxide and nitrogen oxides in the air are absorbed into the interior of the ventilation cavity 114. When the gas enters the ventilation cavity 114, the filter screen 119 is used to filter out some particulate dust inside the gas; with the continuous diversion of the gas, the gas enters the interior of the sulfur dioxide purification box 12, and cooperates with the air permeable pipe 121 on the inner wall of the sulfur dioxide purification box 12 to filter out the sulfur dioxide and nitrogen oxides. The sulfur oxide is guided into the depth of the sulfur dioxide purification box 12. As the bubbles continue to float up and down, the filter sponge plate 124 is used to differentiate the large air masses into small air masses, and at the same time, some impurity particles that are too small are filtered out. At the same time, under the guidance of the diversion chute 122, the particulate dust is accumulated inside the sulfur dioxide purification box 12. As the bubbles continue to rise, the large-pore mesh plate 125 and the small-pore mesh plate 126 are continuously differentiated to continuously split and refine the bubbles, so that the split and refined exhaust gas can fully contact with the alkaline solution inside the sulfur dioxide purification box 12, so that the sulfur dioxide can be fully purified.

[0036] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
