Description

Technical Field

[0001] This utility model relates to the field of zinc oxide production technology, and in particular to a zinc oxide powder feeding system. Background Technology

[0002] Currently, the active zinc oxide used in zinc oxide desulfurizers is prepared using a wet process. During the production of zinc oxide desulfurizers, zinc oxide powder is typically extruded into shape to obtain the final product. To ensure sufficient contact between the zinc oxide powder and the raw materials during the pressing process, resulting in a uniform particle size and consistent product, a zinc oxide powder feeding system is required before production.

[0003] Currently, Chinese patent CN216987442U discloses a zinc oxide powder feeding system, belonging to the technical field of zinc oxide production equipment. It includes a premixing tank, a conveying auger, and a mixing tank. The premixing tank has zinc oxide hoppers and auxiliary material hoppers at its upper left and right ends, respectively. Inclined premixing guide plates are installed on the left and right sides inside the premixing tank, below the zinc oxide hoppers and auxiliary material hoppers. The premixing guide plates on the left and right sides inside the premixing tank are staggered. A discharge port is located at the bottom of the premixing tank, and a feed port is located at the top of the mixing tank. A mixing blade is installed inside the mixing tank, driven by a motor. The conveying auger is connected at both ends to the discharge port of the premixing tank and the feed port of the mixing tank, respectively. A discharge port is located at the bottom of the mixing tank.

[0004] However, when using the above-mentioned device, the premixing box has difficulty in quantitatively adding the added materials, and the materials are easily added in too much or too little, which affects the production quality. Utility Model Content

[0005] The purpose of this invention is to provide a zinc oxide powder feeding system to solve the above-mentioned problems. The size of the feed inlet can be adjusted by the setting adjustment plate, and the amount of material added can be controlled. The material falls onto the distribution plate, which allows the material to fall to the middle position in the premixing box, thus solving the problems mentioned in the background art.

[0006] To address the above problems, this utility model provides a technical solution:

[0007] A zinc oxide powder feeding system includes a premixing box, the top outer wall of which has a feeding port, an adjustment mechanism is provided outside the premixing box, and an anti-blocking mechanism is provided at the bottom inside the premixing box.

[0008] The adjustment mechanism includes an electro-hydraulic rod fixedly connected to one outer wall of the premixing tank. An adjustment port extending into the feed inlet is provided on one outer wall of the premixing tank. An adjustment plate is fixedly connected to the piston rod of the electro-hydraulic rod. The adjustment plate and the inner wall of the adjustment port form a sliding fit. The adjustment plate contacts the inner wall of the feed inlet. A dispensing spring is fixedly connected to the bottom inner wall of the premixing tank. A dispensing plate is fixedly connected to the bottom of the dispensing spring. The dispensing plate is hinged to the top inner wall of the premixing tank. This mechanism allows for the quantitative addition of materials, thereby improving production quality.

[0009] In a preferred embodiment of this utility model, a connecting rod is fixedly connected between the inner walls of both sides of the premix box. A rotating motor is fixedly connected to the bottom of the connecting rod. A rotating shaft is fixedly connected to the output shaft of the rotating motor. Several evenly distributed rotating plates are fixedly connected to both sides of the rotating shaft. The rotating plates can rotate under the rotation of the rotating shaft. The rotation of the output shaft of the rotating motor can cause the rotating shaft to rotate, and the material can be stirred at this time.

[0010] As a preferred embodiment of this utility model, a spiral blade is provided between two adjacent rotating plates. The spiral blade is fixedly connected to the rotating shaft. The spiral blade can rotate when the rotating shaft rotates, and the rotation of the spiral blade can make the material mix from top to bottom.

[0011] As a preferred embodiment of this utility model, the anti-blocking mechanism includes a rotating shaft fixedly connected to the bottom of the rotating shaft, an anti-blocking leaf fixedly connected to the surface of the rotating shaft, and a discharge port opened on the bottom inner wall of the premix box. The anti-blocking leaf is located inside the discharge port. The anti-blocking leaf can cause the rotating shaft to rotate when it rotates, thereby preventing the material from rotating in the inner wall of the discharge port.

[0012] In a preferred embodiment of this utility model, a rotating rod is fixedly connected between the inner walls on both sides of the discharge port. A positioning port is provided at the top of the rotating rod. The inner wall of the positioning port is rotatably connected to the rotating shaft through a bearing. A cleaning plate is fixedly connected to the top of the rotating shaft. The cleaning plate is in contact with the bottom inner wall of the premix box. The cleaning plate can rotate when the rotating shaft rotates, and can rotate the inner wall of the premix box, scraping the bottom inner wall of the premix box, so that the material falls through the discharge port.

[0013] As a preferred embodiment of this utility model, a feeding auger roller is placed below the premix box. The feeding auger roller is connected to the discharge port. The feeding auger roller is designed to convey the falling material.

[0014] The beneficial effects of this utility model are as follows: the electric hydraulic rod allows the adjusting plate to slide within the inner wall of the adjusting port. The movement of the adjusting plate can adjust the size of the feed inlet and control the amount added. Then, the material falls onto the distributing plate, at which point the distributing spring is stretched, allowing the material to fall to the middle position in the premixing box. Starting the rotating motor causes the rotating shaft to rotate, which in turn causes the rotating plate to rotate. The rotation of the rotating plate can perform a stirring operation on the material. After stirring, the material can be conveyed to the feeding auger roller via the anti-clogging blades for transport. Therefore, the added material can be quantitatively added, which can improve the production quality. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example

[0023] Please see Figures 1-4 This utility model provides a technical solution: a zinc oxide powder feeding system, including a premixing box 1, an inlet 2 on the top outer wall of the premixing box 1, an adjustment mechanism on the outside of the premixing box 1, and an anti-blocking mechanism at the bottom inside the premixing box 1.

[0024] The adjustment mechanism includes an electro-hydraulic rod 3 fixedly connected to one side outer wall of the premix box 1. An adjustment port 4 extending into the feed inlet 2 is opened on one side outer wall of the premix box 1. An adjustment plate 5 is fixedly connected to the piston rod of the electro-hydraulic rod 3. The adjustment plate 5 and the inner wall of the adjustment port 4 form a sliding fit. The adjustment plate 5 is in contact with the inner wall of the feed inlet 2. A distributing spring 7 is fixedly connected to the bottom inner wall of the premix box 1. A distributing plate 6 is fixedly connected to the bottom of the distributing spring 7. The distributing plate 6 is hinged to the top inner wall of the premix box 1.

[0025] See Figure 2 The same connecting rod 8 is fixedly connected between the inner walls of the two sides of the premix box 1. A rotating motor 9 is fixedly connected to the bottom of the connecting rod 8. A rotating shaft 10 is fixedly connected to the output shaft of the rotating motor 9. Several evenly distributed rotating plates 11 are fixedly connected to both sides of the rotating shaft 10. The rotating plates 11 can rotate under the rotation of the rotating shaft 10. The rotation of the output shaft of the rotating motor 9 can make the rotating shaft 10 rotate, and the material can be stirred at this time.

[0026] See Figure 2 The same spiral blade 12 is provided between two adjacent rotating plates 11. The spiral blade 12 is fixedly connected to the rotating shaft 10. The spiral blade 12 can rotate when the rotating shaft 10 rotates, and the rotation of the spiral blade 12 can make the material mix from top to bottom.

[0027] See Figure 2-3 The anti-blocking mechanism includes a rotating shaft 13 fixedly connected to the bottom of the rotating shaft 10, and an anti-blocking leaf 14 fixedly connected to the surface of the rotating shaft 13. The bottom inner wall of the premix box 1 is provided with a discharge port 15, and the anti-blocking leaf 14 is located inside the discharge port 15. The anti-blocking leaf 14 can make the rotating shaft 13 rotate when the rotating shaft 10 rotates, which can prevent the material from rotating in the inner wall of the discharge port 15.

[0028] See Figure 2-3 A rotating rod 16 is fixedly connected between the inner walls on both sides of the discharge port 15. A positioning port is provided at the top of the rotating rod 16. The inner wall of the positioning port is rotatably connected to the rotating shaft 13 through a bearing. A cleaning plate 17 is fixedly connected to the top of the rotating shaft 13. The cleaning plate 17 is in contact with the bottom inner wall of the premix box 1. The cleaning plate 17 can rotate when the rotating shaft 13 rotates, and can rotate the inner wall of the premix box 1. It can scrape the bottom inner wall of the premix box 1, so that the material can fall through the discharge port 15.

[0029] See Figure 1-2 Below the premix box 1 is a feeding auger roller 18, which is connected to the discharge port 15. The feeding auger roller 18 can convey the falling material.

[0030] In summary: When using this device, the material is poured into the premixing tank 1 through the feed inlet 2. Activating the electric hydraulic rod 3 allows the adjusting plate 5 to slide within the adjusting port 4. The movement of the adjusting plate 5 adjusts the size of the feed inlet 2, controlling the amount added. The material then falls onto the distributing plate 6, where the distributing spring 7 is stretched, allowing the material to fall to a central position within the premixing tank 1. Activating the rotating motor 9 causes the rotating shaft 10 to rotate, which in turn causes the rotating plate 11 to rotate. The rotation of the rotating plate 11 stirs the material. After stirring, the material is conveyed to the feeding auger roller 18 via the anti-blocking blade 14. Therefore, the added material can be quantitatively added, improving production quality.
