The zinc, indium, arsenic, antimony, tin, silver, lead, cadmium and other valuable metals contained in secondary zinc oxide have high recycling value. When recycling secondary zinc oxide, a feeding device is required to feed the secondary zinc oxide raw material into the reactor at a certain rate for reaction.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention provides a belt quantitative feeding device based on a zinc oxide production line through improvement. The technical solution of the present invention is:

[0035] like Figures 1 to 10 As shown, an embodiment of the present invention provides a belt quantitative feeding device based on a zinc oxide production line, comprising a conveyor 1, an anti-overflow mechanism, a feeding mechanism, and a flattening mechanism arranged in sequence above the conveyor 1; the feeding mechanism comprises a hopper 2 fixed on the upper side of the conveyor 1, a plurality of discharge ports 3 are arranged on the lower side of the hopper 2, and a detection mechanism is arranged at the position of each discharge port 3 on the lower side of the hopper 2, a hollow crossbeam 6 is fixed on the inner side of the hopper 2, and an opening and closing mechanism is arranged between the hollow crossbeam 6 and each discharge port 3; the detection mechanism comprises a detection rod 101 and a sleeve rod 104 rotatably connected to the outer side of the hopper 2, a slide plate 106 is slidably connected to the inner side of the sleeve rod 104, a telescopic rod 105 extending to the outside is fixed to one end of the slide plate 106, one end of the telescopic rod 105 is rotatably connected to the detection rod 101, and a reset spring 107 is sleeved on the outer side of the telescopic rod 105, and a switch 108 is installed at one end of the inner side of the sleeve rod 104.

[0036] Further, the opening and closing mechanism includes a cover plate 4 rotatably connected to the lower end of the discharge port 3, two guide rods 201 and an electromagnet 203 arranged at the inner side of the hollow beam 6 at the position corresponding to the discharge port 3, the outer sides of the two guide rods 201 are slidably sleeved with an iron lifting plate 202, a lifting rod 204 extending to the outer side of the hollow beam 6 is fixed to the lower side of the iron lifting plate 202, and a lifting spring 205 sleeved on the outer side of the lifting rod 204 is connected to the lower side of the iron lifting plate 202, and the lower end of the lifting rod 204 is rotatably connected to an extension connecting rod 206, and the lower end of the extension connecting rod 206 is rotatably connected to the upper side of the cover plate 4;

[0037] By controlling an opening and closing mechanism in the corresponding area to flip the cover plate 4 at the lower end of the discharge port 3 at the corresponding position downward, the material in the hopper 2 can be replenished through the discharge port 3 to the area on the upper side of the conveyor belt 1 where the material is not evenly loaded, thereby replenishing the material loaded on the upper side of the conveyor belt 1.

[0038] Furthermore, a wheel frame 102 is fixed to the lower end of each detection rod 101, and a roller 103 is rotatably connected to the inner side of each wheel frame 102;

[0039] The roller 103 can roll along the material and the upper side of the conveyor belt 1. When there is no material on the conveyor belt 1, the roller 103 rolls from the material to the conveyor belt 1, thereby facilitating the detection rod 101 to rotate up and down, playing a detection role and identifying the area on the upper side of the conveyor belt 1 where no material is carried.

[0040] Furthermore, a dredging mechanism is also provided on the inner side of the hopper 2, and the dredging mechanism includes four end shafts 301 rotatably connected to the two ends of the inner side of the hopper 2 and a first motor 306 installed at one end of the outer side of the hopper 2, the driving end of the first motor 306 is fixedly connected to one end of one of the end shafts 301, a rocker 302 is fixed to one end of each of the four end shafts 301, an intermediate connecting rod 303 is fixed between two rocker arms 302 on the same side, a plurality of horizontal rods 304 are rotatably connected to the outer sides of the two intermediate connecting rods 303 at equal intervals, a lever 305 is fixed to the lower side of each horizontal rod 304, wherein a synchronous wheel 307 is fixed to one end of each of the two end shafts 301, and a synchronous belt 308 is rotatably provided on the outer sides of the two synchronous wheels 307;

[0041] The dredging mechanism stirs and loosens the material inside the hopper 2 to maintain the fluidity of the material, facilitates the material to fall smoothly through the discharge port 3, and improves the accuracy of the material replenishment amount during replenishment.

[0042] Furthermore, the flattening mechanism includes two side plates 401 fixed on both sides of the conveyor 1, a guide groove 402 is provided on one side of the upper end of the two side plates 401, and an adjustment plate 403 is slidably connected to the inner side of the two guide grooves 402, a roller shaft 404 is rotatably connected between the two adjustment plates 403, and a second motor 407 is installed on one side of one of the adjustment plates 403, and the driving end of the second motor 407 is fixedly connected to one end of the roller shaft 404, and a pressure roller 405 is also fixed on the outer side of the roller shaft 404, and two spiral blades 406 are provided at both ends of the outer side of the pressure roller 405, and a height adjustment mechanism is provided between the roller shaft 404 and the two side plates 401;

[0043] Through the leveling mechanism, the materials accumulated on the upper side of the conveyor belt 1 can be pushed to both sides of the belt, so that the accumulated materials can be leveled and evenly distributed on the upper side of the conveyor belt 1, ensuring the accuracy of the feeding amount and preventing the accumulated materials from being fed all in a short time, affecting the efficient reaction.

[0044] Furthermore, the height adjustment mechanism includes an adjustment shaft 408 rotatably connected between the two side plates 401 and a worm 412 rotatably connected to one side of one of the side plates 401. Two adjustment rods 409 are fixed to the outer ends of the adjustment shaft 408. One end of the two adjustment rods 409 is slidably adapted to the outer side of the roller shaft 404 through a push groove 410. A worm wheel 411 is fixed to the end of the adjustment shaft 408 close to the worm wheel 412. The worm wheel 411 is meshed with the worm wheel 412.

[0045] The height adjustment mechanism can adjust the height of the pressure roller 405. The lower side of the pressure roller 405 will limit the height of the material on the upper side of the conveyor belt 1. According to the feeding amount requirement, the pressure roller 405 is adjusted to a suitable height, so that the stacking height of the material on the upper side of the conveyor belt 1 can be adjusted, which is convenient for more accurate adjustment of the feeding amount.

[0046] Furthermore, the spiral directions of the two spiral blades 406 are opposite;

[0047] When the two spiral blades 406 rotate, the materials accumulated on the upper side of the belt of the conveyor 1 can be pushed to both sides of the belt, so that the accumulated materials can be flattened and evenly distributed on the upper side of the belt of the conveyor 1.

[0048] Furthermore, the anti-overflow mechanism includes a collecting cylinder 501 arranged on the upper side of the conveyor 1 and a diaphragm pump 507 installed on the outside of the hopper 2, the input end of the diaphragm pump 507 is connected to a suction pipe 506, and the output end of the diaphragm pump 507 is connected to a recovery pipe 508 extending to the inside of the hopper 2, one end of the suction pipe 506 is connected to a collecting pipe 505, one side of the collecting pipe 505 is connected to the inside of the collecting cylinder 501 through a plurality of branch pipes, a third motor 502 is installed at one end of the outside of the collecting cylinder 501, a central shaft 503 located inside the collecting cylinder 501 is fixed to the driving end of the third motor 502, and a plurality of scraping plates 504 are fixed to the outside of the central shaft 503;

[0049] The anti-overflow mechanism can realize the recovery of the excess material, which can ensure the accuracy of the feeding amount and prevent the excessive amount of material from affecting the reaction, and can also prevent the excess material from piling up and overflowing to both sides of the conveyor 1, causing waste of material.

[0050] Furthermore, an opening is provided at the lower side of the collecting cylinder 501, and a shovel plate 509 parallel to the conveyor 1 is fixed to one side of the opening;

[0051] The shovel plate 509 facilitates shoveling up the accumulated materials, so that the materials accumulated too high can enter the inner side of the collecting tube 501 to be collected.

[0052] Furthermore, a controller 5 is installed on the outside of the hopper 2, and the multiple switches 108 and the multiple electromagnets 203 are electrically connected to the controller 5;

[0053] The controller 5 is used to transmit the trigger signal of the switch 108 to the electromagnet 203, so as to accurately control the discharge port 3 at the corresponding position to discharge the material, thereby replenishing the material in the area above the belt of the conveyor 1.

[0054] Working principle: When in use, start the conveyor 1, put the material on the upper side of the conveyor 1 near the flattening mechanism, and the conveyor 1 will run to transport the material to one end. Since the material is put in randomly, the material is easy to accumulate in one place, resulting in the material being piled too high at that place, while other places on the upper side of the belt of the conveyor 1 do not carry any material;

[0055] When the accumulated materials are transported by the conveyor 1 and contact the flattening mechanism, the second motor 407 of the flattening mechanism drives the roller 404 to rotate, the roller 404 drives the pressure roller 405 to rotate, and the pressure roller 405 drives the two spiral blades 406 on its outer side to rotate. Since the spiral directions of the two spiral blades 406 are opposite, the two spiral blades 406 can push the materials accumulated on the upper side of the belt of the conveyor 1 to the two sides of the belt when they rotate, so that the accumulated materials can be flattened and evenly distributed on the upper side of the belt of the conveyor 1, thereby ensuring the accuracy of the feeding amount and preventing too much material from being put in in a short time to affect the reaction.

[0056] By rotating the worm 412 of the height adjustment mechanism, the worm 412 drives the worm wheel 411 to rotate, the worm wheel 411 drives the adjustment shaft 408 to rotate, and the adjustment shaft 408 drives the two adjustment rods 409 to rotate. Through the sliding adaptation between the roller shaft 404 and the two push grooves 410, when the two adjustment rods 409 rotate, the roller shaft 404 can be driven to move up and down along the guide groove 402, so that the height of the pressure roller 405 can be adjusted. The lower side of the pressure roller 405 will limit the height of the material on the upper side of the conveyor belt 1. According to the feeding amount requirement, the pressure roller 405 is adjusted to a suitable height, so that the stacking height of the material on the upper side of the conveyor belt 1 can be adjusted, so as to facilitate more accurate adjustment of the feeding amount;

[0057] The material flattened by the pressure roller 405 moves to the lower side of the multiple rollers 103 of the detection mechanism. The rollers 103 will naturally roll on the upper side of the flattened material. The rollers 103 roll along the upper side of the material, driving the detection rod 101 to rotate upward by a certain angle. The detection rod 101 drives the telescopic rod 105 to extend to the outside of the sleeve rod 104. At this time, the slide plate 106 is separated from the switch 108. If the local position on the upper side of the conveyor belt 1 does not carry materials of the same height, a roller 103 at the corresponding position will roll from the upper side of the material to the belt of the conveyor 1, thereby driving the detection rod 101 to rotate downward, and at the same time driving the telescopic rod 1 05 retracts toward the inside of the sleeve rod 104, and drives the slide plate 106 close to the switch 108 until the switch 108 is pressed. After the switch 108 is triggered, a signal is sent to the hollow beam 6. After receiving the signal and a certain delay, the hollow beam 6 controls the electromagnet 203 of the opening and closing mechanism at the position of the corresponding roller 103 to be energized to generate electromagnetic suction to the iron lifting plate 202, driving the iron lifting plate 202 to move downward. The iron lifting plate 202 drives the lifting rod 204 to move downward and compress the lifting spring 205. The lifting rod 204 drives a cover plate 4 at the corresponding position to flip downward from a horizontal angle through the extension connecting rod 206, as shown in the attached manual. Figure 7As shown, at this time, the material loaded in the hopper 2 leaks out through the corresponding discharge port 3, and the fallen material just replenishes the area on the upper side of the conveyor belt 1 where the material is not evenly loaded, so that the material loaded on the upper side of the conveyor belt 1 can be replenished, thereby ensuring that each position on the upper side of the conveyor belt 1 can evenly load the material, ensuring the continuity of feeding, further improving the accuracy of the feeding amount, and preventing interruptions in the feeding process from affecting the reaction. When the roller 103 at this location rolls from the conveyor belt 1 to the upper side of the material again, the slide plate 106 and the switch 108 are separated at this time, and the hollow crossbeam 6 does not receive the signal from the switch 108, then after a certain delay, the electromagnet 203 at the corresponding position is controlled to be powered off, and the iron lifting plate 202 is lifted and reset under the elastic force of the lifting spring 205, and then the cover plate 4 is flipped upward by the lifting rod 204 and the extension connecting rod 206, so that the cover plate 4 blocks and closes the lower end of the corresponding discharge port 3;

[0058] The first motor 306 of the dredging mechanism is always running to drive the corresponding end shaft 301 to rotate, and the end shaft 301 drives the rocker 302 at one end to rotate, and the rocker 302 drives the corresponding middle connecting rod 303 to rotate around the axis of the end shaft 301, thereby driving the opposite rocker 302 and the end shaft 301 to rotate synchronously, and at the same time, the opposite end shaft 301 drives a synchronous wheel 307 at one end to rotate, and the synchronous wheel 307 drives another synchronous wheel 307 to rotate through the synchronous belt 308. According to the above principle, the two middle connecting rods 303 can be respectively rotated around the axis of the end shaft 301 at the corresponding position, and the two middle connecting rods 303 drive the multiple horizontal rods 304 to rotate while maintaining a horizontal angle, thereby driving the multiple levers 305 to continuously shift and loosen the materials inside the hopper 2, maintain the fluidity of the materials, facilitate the materials to fall smoothly through the discharge port 3, and improve the accuracy of the feeding amount when feeding;

[0059] After the material is replenished, as the conveyor 1 belt continues to move, if too much material is replenished, the material will be piled up at a higher height. When the accumulated material after replenishment moves to the side of the shovel plate 509 of the anti-overflow mechanism, the material that is higher than the baffles on both sides of the conveyor 1, that is, the material that is higher than the shovel plate 509, will be scooped up by the shovel plate 509 and pushed into the inner side of the collecting cylinder 501 through the opening on the lower side of the collecting cylinder 501. At the same time, the third motor 502 drives the central shaft 503 to rotate, and the central shaft 503 drives the multiple scraping plates 504 on the outer side thereof to rotate clockwise. Each scraping plate 504 scrapes the material at the opening of the collecting cylinder 501 to the inner side of the collecting cylinder 501 in turn, and drives the inner side of the collecting cylinder 501 close to the collecting pipe 505 under the flipping action of multiple scraping plates 504. At the same time, the diaphragm pump 507 sucks through the suction pipe 506, the collecting pipe 505 and multiple branches on one side of the collecting pipe 505, and then discharges it to the inner side of the hopper 2 through the recovery pipe 508, thereby realizing the recovery of excess supplementary materials, which not only ensures the accuracy of the feeding amount, but also avoids the supplementary materials from piling up too high and overflowing to both sides.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
