Description

Technical Field

[0001] This utility model relates to the field of refractory material processing equipment, and in particular to a mixing and stirring device for refractory mud in a carbon roasting furnace. Background Technology

[0002] In the construction and maintenance of carbon roasting furnaces, refractory mortar, as a key refractory lining material, directly determines the material's high-temperature resistance, spalling resistance, and sealing performance through its mixing uniformity, thus affecting the service life and production safety of the carbon roasting furnace. Therefore, in the refractory mortar production process, the mixing and stirring device is the core equipment for ensuring product quality. It is necessary to ensure that the multi-component raw materials, such as refractory aggregates, binders, and additives, form a homogeneous mixture through precise raw material proportioning and thorough mixing.

[0003] Existing mixing devices often add too much raw material at once. Excess material forms a dense accumulation layer at the bottom of the mixing chamber. The mixing blades of existing devices are mostly designed with a fixed rotation speed and a single mixing trajectory, making it difficult to effectively disperse the accumulation layer. This results in the bottom layer of raw material not being able to fully contact the top layer. Secondly, excess material increases the material resistance inside the mixing chamber, forcing the rotation speed of the mixing blades to decrease. This not only prolongs the overall mixing time but also causes differences in the material movement rate in different areas of the mixing chamber. Ultimately, this leads to uneven component distribution in the mixed refractory mortar, with some areas having excessively high binder content and others having exposed aggregate, seriously deviating from product quality standards. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mixing and stirring device for refractory clay in carbon roasting furnaces, which aims to improve the problem that the existing stirring devices will cause uneven mixing when too much raw material is added at one time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing and stirring device for refractory clay in a carbon roasting furnace, comprising a base and a stirring tank fixedly connected to the bottom of the base; a distributing mechanism for batching refractory clay raw materials; a dispersing mechanism for preventing refractory clay raw materials from clumping; a stirring mechanism for stirring the refractory clay raw materials; and a transport mechanism for transporting the stirred material. The distributing mechanism includes a support platform, an electric rotating disk rotatably connected inside the support platform, a distributing pipe inside the electric rotating disk, a storage tank fixedly connected to the top of the support platform, and a connecting pipe fixedly connected to the bottom of the support platform, one end of the connecting pipe being fixedly connected to the inside of the stirring tank. The dispersing mechanism includes a cylinder, a cylinder fixedly connected to the outer wall of the storage tank, a connecting shaft fixedly connected to the output end of the cylinder, a ball screw rotatably connected to the bottom of the connecting shaft, a support rod fixedly connected to the outer wall of the storage tank, the ball screw threadedly connected to the inside of the support rod, a turntable fixedly connected to the bottom of the ball screw, and a scraper fixedly connected to the bottom of the turntable.

[0006] Furthermore, the transport mechanism includes a motor and an auger. The motor is fixedly installed on the outer wall of the base, and the output end of the motor is fixedly connected to the auger. The auger is rotatably connected inside the base.

[0007] Furthermore, the stirring mechanism includes a stirring rod and a top cover, with the stirring rod rotatably connected inside the top cover.

[0008] Furthermore, a second motor is fixedly connected to the top of the top cover, and a second gear is fixedly connected to the output end of the second motor.

[0009] Furthermore, the second gear is rotatably connected inside the top cover, and the bottom of the second gear is fixedly connected to the top of the stirring rod.

[0010] Furthermore, a gear one is rotatably connected inside the top cover, and the gear one meshes with the gear two.

[0011] Furthermore, a second auger is fixedly connected to the bottom of the gear one, and the second auger is rotatably connected to the bottom of the top cover.

[0012] Furthermore, the augers are arranged in a ring array around the stirring rod.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the raw materials of refractory clay are stored in a storage tank. The rotation of the electric rotating disc causes the material distribution pipe to take out the raw materials from the storage tank. The scraper breaks up the agglomerated lumps of the raw materials and then pours the raw materials into the mixing tank through the connecting pipe for mixing. This solves the problem of uneven mixing caused by adding too much raw material at one time and improves the convenience of adding raw materials in batches.

[0014] 2. In this utility model, the second motor drives the second gear to rotate, which in turn drives the stirring rod to rotate and stir. At the same time, the second gear drives the first gear, which in turn drives the auger to rotate, thereby transporting the raw materials at the bottom of the mixing tank upwards for stirring, thus improving the mixing efficiency and quality of the refractory clay raw materials.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 3This utility model provides an embodiment of a mixing and stirring device for refractory clay in a carbon calcining furnace, comprising a base 1 and a stirring tank 2 fixedly connected to the bottom of the base 1, a distributing mechanism for batching refractory clay raw materials, a dispersing mechanism for preventing refractory clay raw materials from clumping, a stirring mechanism for stirring the refractory clay raw materials, and a transport mechanism for transporting the stirred material. The distributing mechanism includes a support platform 5, an electric rotating disk 11 rotatably connected inside the support platform 5, and a distributing pipe 10 opened inside the electric rotating disk 11. The storage tank 6 is fixedly connected to the main body, and the bottom of the support platform 5 is fixedly connected to the connecting pipe 9. One end of the connecting pipe 9 is fixedly connected to the inside of the mixing tank 2. The dispersing mechanism includes a cylinder 8. The cylinder 8 is fixedly connected to the outer wall of the storage tank 6. The output end of the cylinder 8 is fixedly connected to the connecting shaft 16. The bottom of the connecting shaft 16 is rotatably connected to the ball screw 15. The outer wall of the storage tank 6 is fixedly connected to the support rod 12. The ball screw 15 is threadedly connected to the inside of the support rod 12. The bottom of the ball screw 15 is fixedly connected to the turntable 13. The bottom of the turntable 13 is fixedly connected to the scraper 14. Specifically, during the mixing and stirring of refractory clay raw materials, the refractory clay raw materials are first placed inside the storage tank 6. Under the action of gravity, the refractory clay raw materials inside the storage tank 6 will fall into the distribution pipe 10 located inside the electric rotating disk 11. Then, by starting the electric rotating disk 11, it will rotate, and the distribution pipe 10 containing the refractory clay raw materials will move accordingly until it reaches the bottom position of the scraper 14. At this time, the cylinder 8 starts to work, and through its driving force, with the help of the stable connection of the connecting shaft 16, the roller... The ball screw 15 moves vertically downward inside the support rod 12. Due to the inherent characteristics of the ball screw 15, it rotates synchronously during its descent. This rotation further drives the turntable 13 to rotate while descending. In this way, the scraper 14 at the bottom of the turntable 13 can effectively break up any agglomerates that may exist in the refractory mortar raw material inside the distribution pipe 10. As the electric turntable 11 continues to rotate, the refractory mortar raw material inside the distribution pipe 10 will be discharged into the mixing tank 2 through the connecting pipe 9.

[0019] Inside the mixing tank 2, motor 2 7 starts and drives gear 2 19 to rotate. The rotation of gear 2 19 further drives the stirring rod 20 to rotate and stir efficiently. At the same time, during the rotation of gear 2 19, it also drives gear 1 18 to rotate. The rotation of gear 1 18 drives auger 2 21 to rotate. The rotation of auger 2 21 pushes the refractory clay material at the bottom of the mixing tank 2 upward, so that the refractory clay material is repeatedly stirred and mixed inside the mixing tank 2. After being fully mixed, the refractory clay material will finally fall into the base 1. At this time, motor 1 4 starts and drives auger 1 17 to carry out the transportation operation, taking out the evenly mixed refractory clay material from the base 1, completing the entire mixing process.

[0020] Working principle: When mixing refractory clay raw materials, the refractory clay raw materials can be placed into the storage tank 6. The refractory clay raw materials inside the storage tank 6 will fall into the distribution pipe 10 inside the electric rotating disk 11. Then, through the rotation of the electric rotating disk 11, the distribution pipe 10 containing the refractory clay raw materials moves to the bottom of the scraper 14. Then, the cylinder 8 pushes the ball screw 15 vertically down inside the support rod 12 through the connection of the connecting shaft 16. Due to the characteristics of the ball screw 15, the ball screw 15 will rotate during the descent, thereby driving the rotating disk 13 to rotate while descending. The scraper 14 at the bottom of the rotating disk 13 can then scrape the agglomerated refractory clay raw materials inside the distribution pipe 10. The refractory clay material is broken down and then discharged into the mixing tank 2 through the connecting pipe 9 by the rotation of the electric rotating disc 11. Inside the mixing tank 2, the motor 7 drives the gear 19, which in turn drives the stirring rod 20 to rotate and stir. While the gear 19 is rotating, it drives the gear 18 to rotate, which in turn drives the auger 21 to rotate. The rotation of the auger 21 causes the refractory clay material at the bottom of the mixing tank 2 to be transported upward, thus repeatedly stirring and mixing the refractory clay material. The mixed material falls into the base 1 and is then transported by the motor 4 to the auger 17 to remove the mixed material.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
