[0019] Specifically, please refer to Figs. 1 to 3 , Fig. 1 The overall structure schematic diagram of the multi-channel feeding device applied to the static powder classifier provided by the embodiments of the present application, Fig. 2 The local structure schematic diagram of the turnover plate at the swing arm and the connection thereof provided by the embodiments of the present application, Fig. 3A local structure schematic diagram at the buffer hopper provided by the embodiment of the present application. The multi-channel feeding device 100 applied to the static powder classifier comprises a feeding platform 110 connected to the top of the static powder classifier. The feeding platform 110 is located at the top of the static powder classifier and can be supported and fixed by setting a support. The feeding platform 110 and the powder classifier can be stably connected through a flange. The top of the feeding platform 110 is provided with a plurality of buffer hoppers 120. The buffer hoppers 120 have a certain height, thereby increasing the vertical travel height of the process that the material falls into the static powder classifier from the screw conveyor 131. The feeding platform 110 is a hollow structure. The bottom end of the buffer hopper 120 extends into and communicates with the inner cavity of the feeding platform 110. The material in the buffer hopper 120 can enter the inner cavity of the feeding platform 110. A plurality of feeding bins 130 are arranged around the feeding platform 110. The feeding bins 130 are used to place cement raw materials. The feeding bins 130 are connected with the screw conveyors 131. The other end of the screw conveyor 131 extends into the buffer hopper 120 after being inclined upward. The cement raw materials at the feeding bins 130 will be conveyed into the buffer hopper through the screw conveyors 131 and further into the inner cavity of the feeding platform 110 through the buffer hopper and finally into the static powder classifier. A plurality of turnover plates 140 are arranged in parallel in the cavity of the feeding platform 110. The two ends of the turnover plate 140 are provided with a rotating shaft 141. The rotating shaft 141 is rotatably connected to the outer side wall of the feeding platform 110 through a rotating seat. The turnover plate 140 can be flipped along the central axis of the rotating shaft 141 under the drive of an external force. The flipping angle of one time is usually set to 15-35 degrees, thereby changing the sliding direction and the final landing point of the material in the feeding platform 110 when falling into the static powder classifier. With the continuous reciprocating flipping of the turnover plate 140, the material in the buffer hopper 120 will pass through the gap between the turnover plates 140 and enter the static powder classifier. Part of the caked material will be broken after impacting the top end face of the turnover plate 140 and then entering the static powder classifier. Even if the caked material is not completely broken in one impact, it will be crushed, vibrated and impacted by the falling of the upper material during the reciprocating flipping of the turnover plate 140 and finally broken and pass through the gap between the turnover plates 140 and enter the static powder classifier. The gap between the adjacent two turnover plates 140 and the specific number of the turnover plates 140 can be set according to the actual situation. The rotating shaft 141 at one end of the turnover plate 140 extends to the outside of the feeding platform 110 and is sleeved with a positioning ring 142. The outer side of the positioning ring 142 is connected with a driven lever 143. The other end of the plurality of driven levers 143 is hingedly connected with a horizontally arranged synchronization plate 150. One end of the synchronization plate 150 is connected with a driving device 160. The driving device 160 is used to drive the synchronization plate 150 to move. The synchronization plate 150 moves to simultaneously drive the plurality of driven levers 143 to rotate, thereby synchronously completing the flipping of the plurality of turnover plates 140 in the inner cavity of the feeding platform 110.
[0020] As can be seen from the above, in the embodiment of the present application, the turnover plates 140 are arranged in the inner cavity of the feeding platform 110, each of the turnover plates 140 separates the original discharging channel into multiple channels, thereby effectively avoiding the problems of concentrated material feeding drop points and large material layer thickness caused by the cement raw materials falling along the same channel, and the driving device 160 and the synchronous plate 150 and other components are arranged to drive the turnover plates 140, thereby on the one hand, the sliding direction and the final drop point of the materials falling into the static powder concentrator can be flexibly adjusted according to the actual working conditions, and on the other hand, the turnover plates 140 periodically reciprocate, which continuously changes the drop points of the materials and finally makes the materials falling into the static powder concentrator uniformly distributed. In the present application, the buffer cylinder 120 is arranged to increase the falling height of the materials lifted by the screw elevator, thereby crushing the caked materials in the form of impact.
[0021] In some embodiments, the driving device 160 includes a driving lever 161 hinged to the synchronous plate 150 and a driving motor 162 fixed to the outside of the feeding platform 110, one end of the driving lever 161 is connected with a driving shaft, a driven gear is arranged at the driving shaft, the output shaft of the driving motor 162 is connected with a driving gear through a speed reducer, and the driving gear and the driven gear are transmissionally connected through a chain 163. For the convenience of description, the present embodiment provides a specific arrangement mode of the driving device 160, in the present embodiment, the driving lever 161 is similar in structure and material to the driven lever 143, in the working process, the driving motor 162 drives the driving shaft to rotate in sequence through the driving gear, the chain 163 and the driven gear, and then the driving shaft drives the driving lever 161 to rotate, in the process of rotating, the driving lever 161 drags the synchronous plate 150 to move downward while moving to the right, thereby making the synchronous plate 150 drive multiple driven levers 143 to rotate and finally drive the turnover plates 140 to overturn.
[0022] In some embodiments, the top end of the turnover plate 140 is formed with an impact end 144 in arc cross section, and the projection of the impact end 144 covers the turnover plate 140. In the present embodiment, by arranging the arc-shaped impact end 144, on the one hand, the contact area between the turnover plate 140 and the downward materials is increased, thereby enhancing the effect of impacting and crushing the cement raw materials, and on the other hand, the arrangement of the arc surface makes it difficult for the cement raw materials to accumulate on the end surface of the turnover plate 140.
[0023] In some embodiments, a maintenance ladder 170 is arranged on one side of the feeding platform 110, one end of the maintenance ladder 170 is connected to the top of the feeding platform 110, and the other end extends to the ground after being inclined downward. In the present embodiment, through the above arrangement, the operator can climb to the top of the feeding platform 110 through the maintenance ladder 170 to perform maintenance and cleaning work.
[0024] In some embodiments, a side of the buffer cylinder 120 is provided with an access door 121. In the embodiments of the present application, the access door 121 is provided to facilitate the maintenance work on the inside of the buffer cylinder 120.
[0025] In some embodiments, a plurality of grid plates 122 are arranged at the buffer cylinder 120, and the plurality of grid plates 122 are arranged in sequence from top to bottom. In the embodiments of the present application, the height difference between the plurality of grid plates 122 should be designed according to the actual situation. By arranging the grid plates 122, the speed of the part of the agglomerated material will continuously increase during the falling process until it hits the top of the grid plate 122. The grid plate 122 can disperse the collided material, thereby facilitating the subsequent turnover plate 140 to realize the uniform distribution of the static powder concentrator.
[0026] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
