Description

Technical Field

[0001] The invention relates to the technical field of zinc oxide processing, and in particular discloses a zinc oxide powder agglomeration processing device. Background Art

[0002] Zinc oxide production methods are primarily divided into dry and wet processes. Regardless of whether the dry or wet process is used, zinc oxide powder is typically stored in bags. When stored in bags, zinc oxide powder can easily become damp and clump in humid weather. While this clumping does not affect the zinc oxide's physical and chemical properties, it does require secondary processing into a powder before sale to meet customer needs.

[0003] Currently, there is no equipment on the market that performs secondary treatment on zinc oxide powder agglomeration. The industry uses traditional crushers and drying channels to process it. The crusher is used to crush the agglomerated zinc oxide, and then it is sent to the drying channel by a conveyor belt for drying. When the above crusher + drying channel is used to process the agglomerated zinc oxide material, not only does the particle size of the zinc oxide material after final processing fail to meet customer requirements, but the entire equipment occupies a large area and has high operating energy consumption. Based on this, the present application proposes a zinc oxide powder agglomeration processing device, which reduces the equipment volume, simplifies the equipment structure and reduces the equipment operating energy consumption on the basis of ensuring the treatment effect of zinc oxide agglomerates. Summary of the Invention

[0004] The present invention aims to provide a zinc oxide powder agglomeration treatment device to solve the problems in the industry such as large equipment volume, poor treatment effect, and high operating energy consumption when treating zinc oxide agglomerates.

[0005] The present invention is achieved through the following technical solutions:

[0006] A zinc oxide powder agglomeration processing device includes a processing cylinder and a feeding assembly. The processing cylinder is fixedly arranged horizontally and has hollow tubes rotatably arranged at the center of the circle of both end surfaces. The outer ends of the two hollow tubes are commonly connected to a drive assembly. The feeding assembly passes through the hollow tubes and extends into the interior of the processing cylinder for fixed arrangement. The discharge port at the lower end of the processing cylinder is provided with an arc-shaped sealing plate.

[0007] The outer circular surfaces of the two hollow tubes extending into the processing cylinder are evenly connected with a number of radial bars, and the radial bars on the two hollow tubes are aligned one by one, and an arc-shaped shovel plate is rotatably connected between the ends of the two aligned radial bars, and a crushing roller is rotatably provided at one end of the arc-shaped shovel plate, and a swing bar is rotatably connected to the outer surface of the radial bar, and a roller is provided at one end of the swing bar, and a waist-shaped long hole is provided at the other end, and a convex shaft that interacts with the waist-shaped long hole is provided at the side end of the arc-shaped shovel plate, and a guide ring groove that interacts with the roller is provided on the inner wall at both ends of the processing cylinder.

[0008] As a further configuration of the above solution, bearings are provided at the centers of both end surfaces of the processing cylinder, and the hollow tube is rotatably connected to the bearings.

[0009] As a further configuration of the above scheme, the drive assembly includes a drive motor and a transmission box, the drive motor is connected to the power input end of the transmission box, a transmission shaft is provided at both ends of the transmission box, a driving wheel is provided on the transmission shaft, a driven wheel is provided at the outer end of the hollow tube, and a transmission member is provided between the driven wheel and the driving wheel.

[0010] As a further arrangement of the above scheme, the feeding assembly includes a feeding barrel that passes through a hollow tube and extends into the interior of the processing cylinder. A hopper is provided at the outer end of the feeding barrel, a feeding auger is provided inside the feeding barrel, and an auger motor is connected to the end of the feeding auger. A discharge port is provided at the lower end of the feeding barrel located in the processing cylinder.

[0011] As a further configuration of the above solution, the guide ring groove includes a small diameter arc segment at the upper end and a large diameter arc segment at the lower end, and the ends of the small diameter arc segment and the large diameter arc segment are connected by a transition connecting segment.

[0012] As a further configuration of the above solution, it also includes a hot air generator and a cyclone separator, the air outlet end of the hot air generator is connected to the processing cylinder, and the cyclone separator is connected to the processing cylinder through a pipeline.

[0013] As a further arrangement of the above scheme, the air outlet end of the hot air generator is connected to an air supply pipe, and the air supply pipe is provided with a row of blowing nozzles extending to the upper half of the processing cylinder, and an exhaust box is provided at the upper end of the processing cylinder on the opposite side of the blowing nozzle, and the exhaust box is connected to the cyclone separator through a pipe.

[0014] As a further configuration of the above solution, a frame is further included, wherein the processing cylinder is fixed to the bottom plate at the lower end of the frame through vertical plates at both ends, and the driving assembly is arranged at the upper end of the frame.

[0015] During operation, the zinc oxide powder agglomeration processing device disclosed in the present invention puts the agglomerated zinc oxide material into the hopper of the feeding component, and then the feeding auger in the feeding component feeds it along the feeding tube into the interior of the processing cylinder, and then discharges it from the discharge port at the lower end of the feeding tube and falls to the bottom of the processing cylinder.

[0016] Simultaneously, the drive assembly drives the two hollow tubes to rotate around bearings on both ends of the processing cylinder. As the two hollow tubes rotate synchronously, radial bars on either side drive the arc-shaped shovel and swing bar to rotate synchronously. During the swing bar's rotation, the rollers at its ends interact with the guide ring groove. Because the arc diameter at the upper end of the guide ring groove is smaller than the arc diameter at the lower end, the swing bar, when it reaches the lower half of its rotation, presses down the end of the arc-shaped shovel, which is mounted with the crushing roller. This acts together with the inner wall of the processing cylinder, crushing the agglomerated zinc oxide and driving it upward. When the rollers interact with the upper half of the guide ring groove, they lift the crushing roller, forcing the shovel end of the arc-shaped shovel to contact the inner wall of the processing cylinder, shoveling the material adhered to the inner wall of the processing cylinder. The material slides down the upper surface of the arc-shaped shovel and falls to the bottom of the processing cylinder, where it is crushed again by the next set of crushing rollers. This repeated process ensures that the agglomerated material is effectively broken into powder.

[0017] Alternatively, a hot air generator can generate high-temperature hot air, which is then directed into the interior of the processing cylinder, blowing it toward the falling zinc oxide material, thereby drying and removing moisture from the zinc oxide material. After passing through the zinc oxide material, the hot air is piped into a centrifugal separator, where a small amount of zinc oxide powder mixed with the hot air is separated and recovered. Beneficial effects

[0018] When the zinc oxide powder agglomeration processing device disclosed in the present invention processes agglomerated zinc oxide, a feeding component feeds a quantitative amount of material into the processing cylinder, and then under the action of the driving component, multiple arc-shaped shovel plates rotate and operate simultaneously inside the processing cylinder. At the same time, through the structural design of the rocker arm, roller, guide ring groove, etc., the crushing roller at the end of the arc-shaped shovel plate can first crush and crush the zinc oxide, and then scoop it up and throw it down. After repeating the above processing actions many times, the agglomerated zinc oxide can be fully crushed, ensuring that the final processed zinc oxide powder meets customer needs.

[0019] The present invention further provides a hot air generator and a centrifugal separator. The hot air generator is used to introduce hot air into the processing cylinder so that the hot air acts on the zinc oxide material during the falling process, thereby achieving rapid drying of the zinc oxide material and avoiding subsequent re-agglomeration. At the same time, the centrifugal separator can centrifugally separate the exhaust gas, thereby separating and processing a small amount of zinc oxide mixed in the hot air, which not only avoids the waste of zinc oxide powder but also optimizes the workshop environment of the entire process.

[0020] The zinc oxide powder agglomeration processing device disclosed in the present invention has a compact overall structure and occupies a small area. At the same time, the drying process can be completed by only introducing an appropriate amount of hot air through a hot air generator, effectively avoiding the problems of large equipment footprint, high investment cost and excessive operating energy consumption in the process of using a drying channel to dry the material.

[0029] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Figures 1 to 7 , and describes the application in detail with reference to embodiments. Example 1

[0031] Example 1 discloses a zinc oxide powder agglomeration treatment device, see the attached Figures 1-3 The machine frame 1 and the processing cylinder 2 are provided with vertical plates 3 at both ends of the lower surface of the processing cylinder 2, which are horizontally fixed to the bottom plate at the lower end of the machine frame 1. A discharge port 201 is provided at the lower end of the processing cylinder 2, and a corresponding arc-shaped sealing plate 202 is installed in the discharge port 201. The processed zinc oxide material can be discharged by opening the arc-shaped sealing plate 202. In the specific design, the arc-shaped sealing plate 202 can be rotatably connected to the discharge port 201 via a hinge, or it can be directly detachably installed via a connecting piece, as long as the sealing of the discharge port 201 is guaranteed during the processing.

[0032] Bearings 203 are provided at the center of the two end surfaces of the processing cylinder 2, and then a hollow tube 4 is installed in each bearing 203, which passes through the side end of the processing cylinder 2, and a driven wheel 5 is provided at the outer end of each hollow tube 4 extending out of the processing cylinder 2. A power assembly consisting of a transmission box 601 and a drive motor 602 is provided at the upper end of the frame 1, and a transmission shaft 603 is connected to both ends of the transmission box 601. Then, a driving wheel 604 is provided at the outer end of each of the two transmission shafts 603, and a transmission belt 605 or a transmission chain is provided between the driving wheel 604 and the driven wheel 5, so that the hollow tubes 4 at both ends can be driven to rotate synchronously under the action of a single drive motor 602.

[0033] Reference Attachment Figure 4 and attached Figure 7A feed barrel 7 is fixedly and concentrically mounted within the processing cylinder 2, with one end of the feed barrel 7 extending through the hollow tube 4 and out of the processing cylinder 2. A hopper 701 is mounted on the upper surface of the outer end of the feed barrel 7, while a feed auger (not shown) is mounted inside the feed barrel 7. An auger motor 702 for driving the feed auger is also mounted on the outer end of the feed barrel 7. Finally, a discharge port 703 is provided at the lower end of the feed barrel 7 within the processing cylinder 2. During operation, the zinc oxide material to be processed in the hopper 701 is fed into the processing cylinder 2 by the feed auger, and then discharged from the discharge port 703 and falls to the bottom of the inner cavity of the processing cylinder 2.

[0034] Reference Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 Multiple radial bars 8 are evenly connected to the outer circumferential surface of each hollow tube 4, located inside the processing cylinder 2. The radial bars 8 on the two hollow tubes 4 are aligned one by one. A curved scraper plate 9 is rotatably connected between the ends of the two aligned radial bars 8. A crushing roller 10 is rotatably connected to one end of the curved scraper plate 9. Protruding shafts 11 are fixed to each end of the curved scraper plate 9. A swing bar 12 is rotatably connected to the outer surface of the radial bars 8. One end of the swing bar 12 has a waist-shaped elongated hole 121 that interacts with the protruding shaft 11. The other end of the swing bar 12 is rotatably connected to a roller 122 that faces the end wall of the processing cylinder 2.

[0035] Finally, guide ring grooves 204 are concentrically formed on both end walls of the processing cylinder 2 , and the upper end of the guide ring groove 204 is a circular arc segment with a small diameter, and the lower end is a circular arc segment with a large diameter, and the two are connected by a transition connecting section.

[0036] During use, the zinc oxide powder agglomerate processing device disclosed in Example 1 is configured to place the agglomerated zinc oxide material to be processed into a hopper 701. The drive motor 602 and the auger motor 702 are then simultaneously activated. The feed auger, driven by the auger motor 702, delivers the zinc oxide material from the hopper 701 to the lower end of the processing cylinder 2. The drive motor 602 causes the hollow tubes 4 at both ends to rotate synchronously. Because the radial bars 8 are fixedly connected to the hollow tubes 4, the multiple arc-shaped shovel plates 9 rotate within the processing cylinder 2.

[0037] When the arc-shaped shovel plate 9 rotates to the lower half of the processing cylinder 2, the roller 122 acts on the large-diameter arc segment of the lower half of the guide ring groove 204, so that the swing bar 12 can rotate and move the angle, and then under the action of the swing bar 12 and the convex shaft 11, one end of the crushing roller 10 is pressed down and abuts against the inner wall of the processing cylinder 2, and the shoveling end of the arc-shaped shovel plate 9 is lifted, so that the crushing roller 10 acts on the zinc oxide material at the bottom to crush it and lay it upward on the inner wall of the processing cylinder 2.

[0038] As the arc-shaped shovel plate 9 begins to rotate toward the upper half of the processing cylinder 2, the roller 122 interacts with the small-diameter arc segment of the upper half of the guide ring groove 204, thereby lifting the crushing roller 10 and pressing the shovel end of the arc-shaped shovel plate 9 downward, thereby scooping up the material that has been crushed and pressed against the inner wall of the processing cylinder 2. After scooping up to a certain height, the material slides off the upper surface of the arc-shaped shovel plate 9 and slides down to the bottom of the processing cylinder 2 for secondary processing. After multiple rounds of crushing, scooping, and throwing, the agglomerated zinc oxide material is pulverized into powder, which can be discharged from the discharge port 201 by opening the arc-shaped sealing plate 202. Example 2

[0039] Example 2 discloses a zinc oxide powder agglomeration processing device that is optimized and improved based on the technical solution in Example 1. The similarities between it and Example 1 are not described again.

[0040] Reference Attachment Figure 1 and attached Figure 2 The zinc oxide powder agglomeration processing device in this embodiment 2 also includes a hot air generator 13 and a cyclone separator 14. The specific hot air generator 13 can be a hot air blower or a biomass hot air furnace. An air supply pipe 15 is connected to the air outlet end of the hot air generator 13. A row of blowing nozzles 16 are provided on the air supply pipe 15, and the row of blowing nozzles 16 are extended into the upper half of the processing cylinder 2.

[0041] In addition, an exhaust box is provided at the upper end of the processing cylinder 2 on the opposite side of the blowing nozzle 16, and then an air supply pipe is connected between the end of the exhaust box and the cyclone separator 14, and then an exhaust fan (not shown in the figure) is connected to the top of the cyclone separator 14 through a pipe.

[0042] In this embodiment 2, through the design of the above-mentioned hot air generator 13 and cyclone separator 14, the high-temperature gas generated by the hot air generator 13 is sent into the processing cylinder 2 from a row of blowing nozzles 16, and is directly blown onto the zinc oxide material sliding down from the arc-shaped shovel plate 9, thereby effectively removing the moisture in the zinc oxide, and the hot air carries water vapor and a small amount of zinc oxide powder into the cyclone separator 14, so that the zinc oxide powder can be separated and recycled.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
