Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a kiln feeding device for optimizing fluorite content. Background Technology

[0002] In the cement production process, adding 0.7%-1.0% fluorite to the batching improves the burnability of clinker, reduces coal consumption per ton of clinker, and increases clinker strength.

[0003] A relevant reference is Chinese utility model patent CN214568896U, which discloses a feeding device relating to the field of quantitative feeding technology. This feeding device includes: a feeding mechanism; a flexible tube with its top end connected to the feeding mechanism to form a feeding channel; and at least two clamping mechanisms, respectively arranged relative to different parts of the flexible tube along the material flow direction, for alternately clamping the flexible tube. By setting at least two clamping mechanisms, the clamping mechanisms alternately clamp the flexible tube at the end of the feeding process, ensuring that the amount of material flowing out of the flexible tube each time is a fixed value, providing high controllability and facilitating precise control of the feeding quantity to achieve quantitative feeding. Furthermore, the clamping mechanisms do not affect the material's descent when opened, reducing the likelihood of blockage.

[0004] Existing feeding devices can only deliver materials into the rotary kiln and cannot control the ratio between the material and fluorite. They require the material and fluorite to be mixed in advance, which increases the number of steps and affects production efficiency. In addition, the bottom of the existing feeding device is generally connected to the rotary kiln inlet through a pipe structure, which may cause the material to get stuck inside the pipe structure.

[0009] As a preferred embodiment of this utility model, the bottom of the mixing drum is a conical structure, the top cover is connected to the mixing drum by a threaded structure, and the hopper is installed symmetrically on the left and right sides of the mixing drum with the center of the mixing drum as the reference; the hopper can receive materials.

[0010] As a preferred embodiment of this utility model, the bottom end of the hopper is provided with a pipe structure, and the pipe structure at the lower end of the hopper is connected to the inner cavity of the mixing tank. The proportioning motor is fixed to the center of the top of the hopper by a fixing frame. The mixing tank facilitates the entry of materials into the conveying pipe.

[0011] As a preferred embodiment of this utility model, the lower end of the proportioning auger is located inside the lower pipe structure of the hopper, and the top end is located at the center of the conical structure of the hopper. The outer edge of the proportioning auger is in contact with the inner wall of the pipe structure below the hopper. The proportioning auger can drive the material inside the hopper to move downward to the pipe structure at the bottom of the hopper.

[0012] As a preferred technical solution of this utility model, the left and right ends of the connecting frame are fixedly connected to the support frame, the conveying pipe is in an inclined state and a vertical branch is provided above it, and the angle between the vertical branch of the conveying pipe and the inclined structure below is 60 degrees; the connecting frame can restrict the position of the conveying pipe.

[0013] As a preferred embodiment of this utility model, the conveying pipe is fixedly connected to the support frame via a connecting frame, and the top end of the vertical branch of the conveying pipe is fixedly connected to the bottom end of the mixing tank. The connecting shaft is rotatably connected to the conveying pipe via a bearing. The conveying pipe can be connected to the feed inlet of the rotary kiln.

[0014] As a preferred embodiment of this utility model, the front end of the connecting shaft is fixedly connected to the rotating shaft of the feeding motor by means of insertion, the outer edge of the conveying auger is in contact with the inner wall of the conveying pipe, the bottom end of the limiting frame is fixedly connected to the conveying pipe, and the feeding motor is fixedly connected to the conveying pipe through the limiting frame; the feeding motor can drive the connecting shaft to rotate.

[0015] Compared with the prior art, this utility model provides a kiln feeding device with optimized fluorite content, which has the following beneficial effects:

[0016] 1. This utility model features a hopper that is mirror-symmetrically installed on the left and right sides of the mixing tank, with the center of the mixing tank as the reference. A pipe structure is located at the bottom of the hopper, and this pipe structure connects to the inner cavity of the mixing tank. A proportioning motor is mounted at the center of the top of the hopper via a mounting bracket, and its bottom is fixedly connected to the drive shaft. Since the lower end of the proportioning auger is located inside the pipe structure at the bottom of the hopper, and its top end is located at the center of the hopper's conical structure, the outer edge of the proportioning auger contacts the inner wall of the pipe structure below the hopper. When the proportioning motor drives the proportioning auger to rotate via the drive shaft, the auger will move the material downwards into the pipe structure at the bottom of the hopper. The amount of fluorite added is controlled by adjusting the speed of the two proportioning motors. This method allows fluorite to be incorporated into the material during the feeding process, thereby improving production efficiency.

[0017] 2. This utility model, through the setting of the conveying auger, has a rotating connection between the connecting shaft and the conveying pipe via bearings. The top end is fixedly connected to the rotating shaft of the feeding motor. When the feeding motor drives the connecting shaft to rotate, the conveying auger fixed to the outside of the connecting shaft will rotate synchronously, thereby driving the material to move towards the bottom of the conveying pipe, preventing the material from clogging inside the conveying pipe. At the same time, because the falling speed of the material is limited by the proportioning auger, after the material enters the mixing tank under the guidance of the pipe structure at the bottom of the hopper, it will enter the conveying pipe under the guidance of the conical structure at the bottom of the mixing tank. A large amount of material cannot accumulate inside the mixing tank. This method can avoid the situation of material blockage. Attached Figure Description

[0026] Please see Figure 1 - Figure 4In this embodiment, a kiln feeding device for optimizing fluorite content includes: a support frame 1, a mixing tank 11 fixedly installed above the support frame 1, a top cover 12 fixedly installed at the top of the mixing tank 11, a hopper 13 fixedly installed at the top of the support frame 1, a fixing frame 14 fixedly installed at the top of the hopper 13, a proportioning motor 15 fixedly installed at the center of the fixing frame 14, a drive shaft 16 inserted and fixed at the bottom end of the shaft of the proportioning motor 15, a proportioning auger 17 fixedly installed on the outside of the drive shaft 16, a connecting frame 18 fixedly installed on the inside of the support frame 1, a conveying pipe 19 fixedly installed at the center of the connecting frame 18, a bearing 110 fitted at the front end of the conveying pipe 19, a connecting shaft 111 inserted and installed inside the bearing 110, a conveying auger 112 fixedly installed on the outside of the connecting shaft 111, a feeding motor 113 fixedly installed at the front end of the connecting shaft 111, and a limit frame 114 fixedly installed on the outside of the feeding motor 113.

[0027] The bottom of the mixing tank 11 is conical. The top cover 12 is connected to the mixing tank 11 via a threaded structure. The hopper 13 is mirror-symmetrically installed on the left and right sides of the mixing tank 11 with the center as the reference. The bottom of the hopper 13 is provided with a pipe structure, and the pipe structure at the lower end of the hopper 13 is connected to the inner cavity of the mixing tank 11. The proportioning motor 15 is fixed to the center of the top of the hopper 13 via a fixing bracket 14. The lower end of the proportioning auger 17 is located inside the pipe structure at the lower end of the hopper 13, and the top end is located at the center of the conical structure of the hopper 13. The outer edge of the proportioning auger 17 contacts the inner wall of the pipe structure below the hopper 13. The left and right ends of the connecting frame 18 are fixedly connected to the support frame 1. The conveying pipe 19 is inclined and has a vertical branch at the top. The angle between the vertical branch of the conveying pipe 19 and the inclined structure below is 60 degrees. The conveying pipe 19 is fixedly connected to the support frame 1 through the connecting frame 18. The top of the vertical branch of the conveying pipe 19 is fixedly connected to the bottom of the mixing tank 11. The connecting shaft 111 is rotatably connected to the conveying pipe 19 through the bearing 110. The front end of the connecting shaft 111 is fixedly connected to the rotating shaft of the feeding motor 113 through an insertion method. The outer edge of the conveying auger 112 is in contact with the inner wall of the conveying pipe 19. The bottom end of the limiting frame 114 is fixedly connected to the conveying pipe 19. The feeding motor 113 is fixedly connected to the conveying pipe 19 through the limiting frame 114.

[0028] Specifically, both the proportioning motor 15 and the feeding motor 113 are variable frequency motors, model TYCP132-8. The support frame 1 restricts the relative position between the mixing tank 11 and the hopper 13. The mixing tank 11 connects the two hoppers 13 to the conveying pipe 19. The hoppers 13 receive materials and fluorite. The proportioning motor 15 is installed at the center of the top of the hopper 13 via the fixing frame 14, and the bottom of the proportioning motor 15 is fixedly connected to the drive shaft 16. Since the lower end of the proportioning auger 17 is located inside the lower pipe structure of the hopper 13, and the top end is located at the center of the conical structure of the hopper 13, the outer edge of the proportioning auger 17 contacts the inner wall of the lower pipe structure of the hopper 13. 5. When the proportioning auger 17 is driven to rotate by the drive shaft 16, the proportioning auger 17 will drive the material downward to the pipe structure at the bottom of the hopper 13. The amount of fluorite is controlled by controlling the speed of the two proportioning motors 15. The connecting frame 18 can limit the position of the conveying pipe 19. Since the connecting shaft 111 is rotatably connected to the conveying pipe 19 through the bearing 110, and its top end is fixedly connected to the rotating shaft of the feeding motor 113, when the feeding motor 113 drives the connecting shaft 111 to rotate, the conveying auger 112 fixed to the outside of the connecting shaft 111 will rotate synchronously, thereby driving the material to move to the bottom of the conveying pipe 19. The limiting frame 114 can limit the position of the feeding motor 113.

[0029] In use, the hopper 13 is mirror-symmetrically installed on the left and right sides of the mixing tank 11, with the center as the reference. A pipe structure is provided at the bottom of the hopper 13, and the pipe structure at the lower end of the hopper 13 is connected to the inner cavity of the mixing tank 11. The proportioning motor 15 is installed at the center of the top of the hopper 13 via a fixing bracket 14, and the bottom end of the proportioning motor 15 is fixedly connected to the drive shaft 16. Since the lower end of the proportioning auger 17 is located inside the lower pipe structure of the hopper 13, and the top end is located at the center of the conical structure of the hopper 13, the outer edge of the proportioning auger 17 contacts the inner wall of the lower pipe structure of the hopper 13. When the proportioning motor 15 drives the proportioning auger 17 to rotate via the drive shaft 16, the proportioning auger 17 will move the material downwards into the pipe structure at the bottom of the hopper 13. The speed of the two proportioning motors 15 is controlled to regulate the material flow. The method of adding fluorite allows fluorite to be incorporated into the material during the feeding process, thereby improving production efficiency. Since the connecting shaft 111 is rotatably connected to the conveying pipe 19 through the bearing 110, and its top end is fixedly connected to the rotating shaft of the feeding motor 113, when the feeding motor 113 drives the connecting shaft 111 to rotate, the conveying auger 112 fixed to the outside of the connecting shaft 111 will rotate synchronously, thereby driving the material to move towards the bottom of the conveying pipe 19, preventing the material from clogging inside the conveying pipe 19. Since the falling speed of the material is limited by the proportioning auger 17, after the material enters the mixing tank 11 under the guidance of the bottom pipe structure of the hopper 13, it will enter the conveying pipe 19 under the guidance of the conical structure at the bottom of the mixing tank 11. A large amount of material cannot accumulate inside the mixing tank 11, thus avoiding material blockage.
