Description

Technical Field

[0001] The invention belongs to the technical field of zinc powder processing and conveying, in particular to a zinc powder processing and conveying device. Background Art

[0002] Zinc powder is a dark gray powdered metal zinc with strong anti-rust and corrosion resistance. At the same time, it has extremely strong hiding power and is an important raw material for making zinc oxide. Zinc powder processing is a process involving multiple steps, including smelting, cooling and crushing, etc. In order to maintain the continuity of the production process, conveying equipment such as zinc powder tube chain conveyor will be set up to ensure the smooth and efficient transfer of zinc powder between these links.

[0003] A patent application with publication number CN116873603A discloses a zinc powder conveying device, including a support frame, a closed barrel, and a belt conveyor. A closed barrel is installed on the upper end of the support frame, and a feed port and a discharge port are respectively provided at the upper left end and the lower right end of the closed barrel. A belt conveyor is installed inside the closed barrel. The device adopts a stirring mechanism to drive a telescopic elastic column through a rotating motor so that an impeller stirs the zinc powder. During the stirring process, the trapezoidal plate drives the telescopic elastic column to move up and down through the cooperation of the protrusion and the top extension block, so that the impeller moves up and down and then stirs the zinc powder in layers.

[0004] There are still some problems in the actual application of the above scheme. During the zinc powder transportation process, the equipment can stir the zinc powder in layers, but the zinc powder will contact and rub against each other during the stirring process. Moreover, since the zinc powder has a high density and surface area, static electricity will be generated between the zinc powder particles when they rub against each other, which will increase the attraction between the zinc powder particles and increase the possibility of zinc powder agglomeration. The fluidity of the agglomerated zinc powder will be affected, making it difficult to distribute it evenly in coatings, electroplating or other applications, resulting in unstable product quality and degraded performance.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1: Figures 1 to 6 As shown, a zinc powder processing and conveying device according to an embodiment of the present invention comprises a base frame 1, a conveying device 2 is provided at the upper end of the base frame 1, a processing structure 4 is provided at the upper end of the conveying device 2, a feeding structure 3 is provided at the upper end of the processing structure 4, and a collecting bucket 5 is provided at the lower end of the processing structure 4, and the collecting bucket 5 is used in conjunction with the processing structure 4; the conveying device 2 comprises: a lower conveying roller 21, and a plurality of lower conveying rollers 21 are rotatably connected to the upper surface of the base frame 1; an upper conveying roller 22, and the upper conveying roller 22 is rotatably connected to the upper surface of the base frame 1; the processing structure 4 comprises: a transfer plate 401, the transfer plate 401 is provided at the upper end of the base frame 1, and the upper surface of the transfer plate 401 is in contact with the upper conveying roller 22, and the lower surface of the transfer plate 401 is in contact with the upper conveying roller 22. The surface is in contact with the lower conveying roller 21; a placement groove 402, a plurality of placement grooves 402 are opened on the surface of the transfer plate 401; a placement plate 411, the placement plate 411 is arranged on the lower surface of the placement groove 402, and the placement plate 411 is in contact with the lower surface of the transfer plate 401 in the initial state; a feeding barrel 419, the feeding barrel 419 is arranged inside the base frame 1, and one end of the feeding barrel 419 extends to the lower surface of the transfer plate 401, and the other end of the feeding barrel 419 extends to the upper surface of the collecting bucket 5; the feeding structure 3 includes: a feeding frame 31, the feeding frame 31 is arranged at the upper end of the transfer plate 401; a feeding port 35, the feeding port 35 is arranged on the lower surface of the feeding frame 31, and one end of the feeding port 35 extends to the upper end of the placement groove 402.

[0038] Specifically, the existing process will first perform zinc powder processing operations before conveying the zinc powder. First, the zinc powder raw material is smelted. The raw material is a zinc block. The cleaned and pre-treated zinc block is sent to a smelting furnace for high-temperature smelting to melt the zinc block into liquid zinc. The liquid zinc is then cooled to form a solid zinc block or zinc ingot. The cooled zinc blocks or zinc ingots are crushed in a crusher to further reduce their particle size. The crushed zinc blocks or zinc ingots are crushed in a pulverizer. Through continuous grinding, the raw materials are processed into powder. The powdered substances are zinc powder. Subsequently, due to the large amount of these powders, the zinc powder is placed on a belt for conveying, and on the conveying belt The zinc powder is packaged and collected at the tail of the belt, but this method of conveying zinc powder is to collectively convey a large amount of zinc powder. However, since zinc powder is a metal powder with a high density and specific surface area, these zinc powder particles will rub against each other during the conveying process, thereby generating static electricity between them, which will lead to an increase in the attraction between the particles, thereby increasing the possibility of agglomeration, and these agglomerated zinc powders cannot be fully utilized, resulting in a waste of resources. For this purpose, a zinc powder conveying device is designed. When the zinc block is processed into zinc powder, it will enter the interior of the feed frame 31. At this time, the lower conveying roller 21 is started, and the lower conveying roller 21 will drive the transfer plate 401 to transfer in the direction of the feed frame 31, and Since the upper part of the transfer plate 401 is in contact with the upper conveying roller 22, the transfer plate 401 in transit is limited so that the transfer plate 401 can be transported smoothly. When the placement slot 402 is transferred to the bottom of the feeding port 35, the lower conveying roller 21 is stopped, and the feeding port 35 is opened to allow the zinc powder to fall into the first placement slot 402. Then, the lower conveying roller 21 is started again. When the second placement slot 402 moves to the bottom of the feeding port 35, the feeding port 35 is opened again to allow the zinc powder to fall into the second placement slot 402. At this time, the first placement slot 402 has moved to the top of the feeding barrel 419. The placement plate 411 under the first placement slot 402 is started to place The plate 411 will rotate and dump the zinc powder on the surface of the placement plate 411. The dumped zinc powder will enter the interior of the feeding cylinder 419 and fall freely, and finally move to the interior of the collecting bucket 5 for collection. By setting up a plurality of placement slots 402 and the feeding cylinder 419, in the process of conveying the zinc powder, large-area accumulation conveying is abandoned, and batch conveying is adopted. This conveying method will reduce the friction between the zinc powders, thereby reducing the possibility of zinc powder agglomeration during transportation. In the process of collection, the zinc powder is allowed to enter the interior of the collecting bucket 5 by free fall, which can reduce the friction and collision between the zinc powder particles and reduce the risk of zinc powder agglomeration during collection.

[0039] like Figures 1 to 7As shown, the processing structure 4 also includes: a fixed rod 425, which is rotatably connected to one end of the lower surface of the transfer plate 401 close to the placement plate 411, and the placement plate 411 is connected to the fixed rod 425; a meshing gear 412, which is arranged at both ends of the fixed rod 425; a connecting rack 413, which is arranged at the upper end of the base frame 1, and the connecting rack 413 is meshed with the meshing gear 412; the loading structure 3 includes: a placement frame 32, which is arranged on both sides of the base frame 1, and a feeding frame 31 is placed above the placement frame 32.

[0040] Specifically, when the zinc powder falls into the second placement groove 402, the meshing gear 412 below the first placement groove 402 will contact the connecting rack 413 and drive the meshing gear 412 to rotate. When the meshing gear 412 rotates, it will drive the placement plate 411 to rotate through the fixed rod 425, thereby pouring the zinc powder on the surface of the placement plate 411 into the interior of the feeding barrel 419.

[0041] like Figure 7 As shown, a limiting ring 424 is provided at the upper end of the placing plate 411 , and the limiting ring 424 is in contact with the bottom of the transfer plate 401 .

[0042] Specifically, by setting a limiting ring 424 at the upper end of the placing plate 411, when zinc powder falls on the surface of the placing plate 411, the limiting ring 424 on the surface of the placing plate 411 will limit the zinc powder, thereby preventing the zinc powder from flowing out from both sides of the placing plate 411 when the placing plate 411 rotates, and a notch is provided at one end of the limiting ring 424 close to the feeding barrel 419, so that the zinc powder can flow out from the notch, which is convenient for collecting the zinc powder.

[0043] like Figures 1 to 5 As shown, a stirring shaft 33 is rotatably connected inside the feeding frame 31 , a contact strip 34 is fixedly connected to the arc surface of the stirring shaft 33 , and the contact strip 34 is in contact with the zinc powder.

[0044] Specifically, by setting a contact strip 34 inside the feed frame 31, when the zinc powder enters the feed frame 31 for the first time, the stirring shaft 33 is started to rotate, and the stirring shaft 33 will drive the contact strip 34 to rotate together, so as to stir the zinc powder, and the stirring shaft 33 only rotates one circle, and the rotation speed is slow. This slight stirring can break up the tiny lumps that have been formed, and will not cause friction between the zinc powders.

[0045] like Figures 1 to 13 As shown, the lower end of the placement frame 32 is rotatably connected to two rotating frames 420 , and an adjusting half ring 421 is provided at one end of the two rotating frames 420 close to each other, and the adjusting half ring 421 is in contact with the collection bucket 5 .

[0046] Specifically, when the zinc powder enters the collecting bucket 5 through the feeding cylinder 419, the upper end of the collecting bucket 5 will contact the bottom of the feeding cylinder 419, thereby ensuring the closure between the collecting bucket 5 and the feeding cylinder 419. For this purpose, a rotating frame 420 is set at the lower end of the placing frame 32, and an adjusting half ring 421 is provided at one end of the rotating frame 420. When the collecting bucket 5 is placed at the lower end of the feeding cylinder 419, the rotating frame 420 is rotated so that the two adjusting half rings 421 contact the side wall of the collecting bucket 5, so that the collecting bucket 5 can be fixed, so that the collecting bucket 5 and the feeding cylinder 419 can be kept closed.

[0047] like Fig.13 As shown, a compression spring 423 is provided at one end of the adjusting half ring 421, and the compression spring 423 is in a relaxed state in the initial state.

[0048] Specifically, when the two adjusting half rings 421 clamp and fix the collecting bucket 5, if the cross-section of the collecting bucket 5 is different, the clamping force of the adjusting half ring 421 is also different. By setting a compression spring 423 at one end of the adjusting half ring 421, if the cross-section of the collecting bucket 5 is larger, the compression spring 423 will be compressed, thereby ensuring that the adjusting half ring 421 abuts against the side wall of the collecting bucket 5, and during the abutment process, the collecting bucket 5 will also be fixed due to the elastic force applied by the compression spring 423.

[0049] Embodiment 2: Figures 1 to 5 As shown, in contrast to Example 1, another implementation of the present invention is that a filter net 403 is provided inside the transfer plate 401 , and the filter net 403 is at a certain distance from the placement plate 411 .

[0050] Specifically, when the zinc powder falls into the placement groove 402 from the feed port 35, it will first contact the filter 403. At this time, the filter 403 is started and the filter 403 will shake inside the transfer plate 401, so that the zinc powder can pass through the holes of the filter 403. The impurities in the zinc powder will remain on the surface of the filter 403, thereby achieving impurity filtration of the zinc powder. Setting the filter 403 to filter in a shaking manner can also make the zinc powder flat on the surface of the filter 403, thereby making the impurity filtration effect better.

[0051] like Figures 1 to 10As shown, the base frame 1 is internally rotatably connected with an auxiliary gear 414, and first coil springs 415 are provided at both ends of the auxiliary gear 414. Sliding rods 404 are provided on both sides of the filter screen 403, and one end of the sliding rod 404 is in contact with the transfer plate 401. The arc surface of the sliding rod 404 is sleeved with a return spring 405, and one end of the return spring 405 is connected to the transfer plate 401. A fixed rack 407 is provided at the lower end of the transfer plate 401, and the fixed rack 407 is provided at the lower end of the transfer plate 401. 07 is meshed with the auxiliary gear 414, a vibration connecting plate 406 is provided at the lower end of the filter screen 403, and an arc-shaped connecting block 416 is provided at the lower end of the vibration connecting plate 406, and the arc surface of the arc-shaped connecting block 416 is in contact with the auxiliary gear 414, and the arc surface of the arc-shaped connecting block 416 is sleeved with a second coil spring 417, and a limit plate 418 is provided at one end of the lower surface of the vibration connecting plate 406 close to the arc-shaped connecting block 416, and the limit plate 418 is in contact with the vertical surface of the arc-shaped connecting block 416.

[0052] Specifically, by setting a fixed rack 407 at the lower end of the transfer plate 401, when the zinc powder falls on the upper end of the filter screen 403, the lower conveying roller 21 will drive the transfer plate 401 to continue to move. During the movement, the fixed rack 407 will mesh with the auxiliary gear 414 and drive the auxiliary gear 414 to rotate. During the rotation of the auxiliary gear 414, the first coil spring 415 will also rotate with the auxiliary gear 414. When the auxiliary gear 414 is no longer meshed with the fixed rack 407, the first coil spring 415 will release the elastic force and drive the auxiliary gear 414 to rotate. Subsequently, during the rotation process, the arc connection block 416 will come into contact with the arc connection block 416. Since the arc surface of the arc connection block 416 abuts against the auxiliary gear 414, the arc connection block 416 will not mesh with the auxiliary gear 414 at this time, and the arc connection block 416 will drive the vibration plate 406 to vibrate, thereby driving the filter screen 403 to vibrate. When the transfer plate 401 is reset and the arc connection block 416 comes into contact with the auxiliary gear 414, since there is no abutment of the limit plate 418, the arc connection block 416 will rotate, thereby not affecting the reset of the vibration plate 406.

[0053] like Fig.12 As shown, a conveying threaded rod 422 is rotatably connected inside the material barrel 419 , and the conveying threaded rod 422 is in contact with the inner wall of the material barrel 419 .

[0054] Specifically, by setting a conveying threaded rod 422, when the zinc powder enters the interior of the feeding barrel 419, the conveying threaded rod 422 is started to rotate. Since the conveying threaded rod 422 is in contact with the inner wall of the feeding barrel 419, the conveying threaded rod 422 will drive the zinc powder to move. When the zinc powder enters the interior of the collecting bucket 5 by free fall, it can also limit the zinc powder.

[0055] like Figure 5As shown, a telescopic cylinder 410 is provided on the side wall of the feed frame 31 , a pressing cloth 408 is provided inside the telescopic cylinder 410 , and the pressing cloth 408 is in contact with the filter screen 403 , and a blower 409 is provided on one end of the side wall of the feed frame 31 close to the telescopic cylinder 410 .

[0056] Specifically, when the transfer plate 401 moves to the top of the pressing cloth 408, the telescopic cylinder 410 is started, and the telescopic cylinder 410 will drive the pressing cloth 408 to move toward the direction of the filter 403, and contact the zinc powder above the filter 403, and will press the zinc powder that has agglomerated during production, so that the zinc powder can pass through the surface of the filter 403. When the transfer plate 401 is reset, the blower 409 is started, and the blower 409 will blow air toward the surface of the filter 403, thereby blowing away impurities on the surface of the filter 403.

[0057] Working principle: Before the zinc powder is transported, the zinc powder processing operation will be carried out first. First, the zinc powder raw material is smelted. The raw material is zinc block. The cleaned and pre-treated zinc block is sent to the smelting furnace for high-temperature smelting to melt the zinc block into liquid zinc. The liquid zinc is then cooled to solid zinc block or zinc ingot. These cooled zinc blocks or zinc ingots will enter the crusher for crushing to further reduce their particle size. The crushed zinc blocks or zinc ingots enter the pulverizer for crushing. Through continuous grinding, the raw material is processed into powder. These powdery substances are zinc powder. The zinc powder is then passed into the interior of the material frame 31. At this time, the following is started. The conveying roller 21, the lower conveying roller 21 will drive the transfer plate 401 to transfer in the direction of the feeding frame 31, and because the upper conveying roller 22 is in contact with the upper part of the transfer plate 401, the transfer plate 401 in transfer will be limited, so that the transfer plate 401 can be smoothly transported. When the placement slot 402 is transferred to the lower part of the feeding port 35, the lower conveying roller 21 is stopped, and the feeding port 35 is opened, so that the zinc powder falls into the first placement slot 402, and will first contact with the filter screen 403 to filter the impurities of the zinc powder. Then the lower conveying roller 21 will drive the transfer plate 401 to continue to move, and the rack is fixed during the movement. 407 will mesh with the auxiliary gear 414 and drive the auxiliary gear 414 to rotate. During the rotation of the auxiliary gear 414, the first coil spring 415 will also rotate with the auxiliary gear 414. When the auxiliary gear 414 is no longer meshed with the fixed rack 407, the first coil spring 415 will release its elastic force and drive the auxiliary gear 414 to rotate. Then, during the rotation, it will contact the arc-shaped connecting block 416. Since the arc surface of the arc-shaped connecting block 416 is in contact with the auxiliary gear 414, the arc-shaped connecting block 416 will not mesh with the auxiliary gear 414 at this time, and the arc-shaped connecting block 416 will drive the vibration connecting plate 406 to vibrate, thereby driving the filter screen 403 to vibrate. When the zinc powder falls into the second placement groove 402, the meshing gear 412 below the first placement groove 402 will contact the connecting rack 413 and drive the meshing gear 412 to rotate. When the meshing gear 412 rotates, it will drive the placement plate 411 to rotate through the fixed rod 425, and dump the zinc powder on the surface of the placement plate 411. The dumped zinc powder will enter the interior of the feeding barrel 419 and fall freely, and finally move to the interior of the collecting bucket 5 for collection, thereby completing the transportation of the zinc powder.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
