Description

Technical Field

[0001] This utility model relates to the field of vertical mill technology, and in particular to a feeding hopper for a vertical mill. Background Technology

[0002] The feed hopper of a vertical mill is an important component of the vertical mill system. The following is a detailed introduction to it. The main function of the feed hopper is to hold a certain amount of material to be ground. It can play the role of raw material buffering and storage, and at the same time, it can ensure continuous and stable feeding of the vertical mill, avoiding the mill from running dry or stopping due to untimely material supply.

[0003] Existing vertical mills typically use either steam or hot air heating to heat the raw materials in their feed hoppers. Steam heating involves steam pipes running inside the hopper or jacket, transferring heat to the hopper walls and materials. However, this method is relatively ineffective at heating materials located in the middle of the hopper. Hot air heating, on the other hand, involves introducing hot air into the feed hopper. This is usually done using a dedicated hot air furnace to generate hot air, which is then introduced into the hopper to exchange heat with the materials, raising their temperature. However, during use, the hot air often doesn't reach areas covered by the material, easily causing raw materials to adhere to the walls and inside the hopper. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a feeding hopper for a vertical mill to more accurately resolve these issues.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a feeding bin for a vertical mill, including a bin body and a first shaft rotatably connected to the top center of the bin body. A rod is connected to the bottom of the first shaft, and one end of the rod passes through the top of the bin body and is located inside the bin body. An installation groove is formed between the shaft and the bin body, and a first heating element is detachably connected to the installation groove. Several evenly distributed stirring rods are arranged circumferentially on the upper end surface of the rod, and a scraper is connected to one end of each stirring rod. Both the scraper and one side of the stirring rod are tapered. Two mounting brackets are arranged on one side of the top of the bin body, and a motor is arranged between the two mounting brackets. The output end of the motor is connected to a second shaft, and a transmission belt is arranged between the first shaft and the second shaft. A heating chamber is formed on the bin body, and a second heating element is arranged inside the heating chamber.

[0007] Furthermore, in this utility model, the first heating element includes a base plate, a heating tube is provided at the bottom of the base plate, a battery compartment is provided at the top of the base plate, and a storage battery is provided inside the battery compartment.

[0008] Furthermore, the hopper body includes a storage end and a discharge end disposed at the bottom of the storage end.

[0009] Furthermore, in this invention, a spiral shaft is provided on the outer surface of the lower end face of the rod, and the spiral shaft is located inside the feeding end.

[0010] Furthermore, the rod, scraper, and spiral shaft are all made of aluminum alloy.

[0011] Furthermore, the present invention provides an inlet pipe on one side of the top of the silo body and support frames on both sides of the bottom of the silo body.

[0012] Furthermore, both the first shaft and the second shaft are concave in shape.

[0013] The beneficial effects of this utility model are:

[0014] The first heating element heats the rod body, and the heat from the rod body is conducted to the stirring rod, scraper, and spiral shaft, and then diffuses into the interior of the bin through these components. The heat from the rod body and stirring rod gradually heats the raw materials located in the middle and at the discharge end of the bin. The second heating element heats the inner wall of the bin and the raw materials located at the inner edge of the bin. The combination of these two heating structures enables large-scale heating of the raw materials inside the bin and minimizes the occurrence of raw material agglomeration.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0020] refer to Figure 1-3 A feeding bin for a vertical mill includes a bin body 1 and a first shaft 2 rotatably connected to the top center of the bin body 1. A rod 21 is connected to the bottom of the first shaft 2, and one end of the rod 21 passes through the top of the bin body 1 and is located inside the bin body 1. An installation groove 22 is opened in the shaft and the bin body 1. A first heating element 3 is detachably connected in the installation groove 22. Several evenly distributed stirring rods 23 are arranged circumferentially on the upper end surface of the rod 21. A scraper 24 is connected to one end of the stirring rod 23. One side of the scraper 24 and the stirring rod 23 are both tapered. Two mounting brackets 41 are arranged on one side of the top of the bin body 1. A motor 4 is arranged between the two mounting brackets 41. The output end of the motor 4 is connected to a second shaft 42. A transmission belt 43 is arranged between the first shaft 2 and the second shaft 42. A heating chamber 5 is opened on the bin body 1, and a second heating element 51 is arranged in the heating chamber 5.

[0021] The motor 4 drives the second shaft 42 to rotate, and the rotating second shaft 42 drives the shaft and stirring rod 23 to rotate through the transmission belt 43. The stirring rod 23 then completes the stirring and crushing work of the raw materials in the bin 1, which can effectively prevent the accumulation of raw materials. At the same time, during the rotation of the shaft and stirring rod 23, the first heating element 3 heats the rod 21. The heat absorbed by the rod 21 is transferred to the stirring rod 23 and gradually diffuses to the surrounding area of ​​the stirring rod 23, thereby completing the crushing and heating work of the raw materials located in the middle of the bin 1. This can effectively prevent the raw materials from clumping. Meanwhile, the heating bin 5 and the second heating element 51 can heat the raw materials located at the inner edge of the bin 1. This heating method, in combination with the heating method of the first heating element 3, can achieve large-scale heating of the raw materials inside the bin 1 and maximize the prevention of raw material clumping.

[0022] In this embodiment, the scraper 24 can rotate synchronously with the stirring rod 23 during rotation and scrape the raw materials attached to the inner wall of the bin 1, thereby avoiding the waste of raw materials.

[0023] In this embodiment, the rotation structure between the chamber body 1 and the shaft is an existing bearing structure or other rotation structure. The top center of the chamber body 1 is provided with a mounting groove 22, and a bearing is provided in the mounting groove 22.

[0024] In this embodiment, the second heating element 51 can adopt an existing heating structure, such as an electric heating tube 32 or a steam heating coil, etc.

[0025] like Figure 3 As shown, the first heating element 3 includes a base plate 31, a heating tube 32 is provided at the bottom of the base plate 31, a battery compartment 33 is provided at the top of the base plate 31, and a storage battery is provided inside the battery compartment 33.

[0026] The battery compartment 33 and the battery provide power to the heating tube 32. After being powered on, the heating tube 32 will generate heat, which will be gradually conducted to the rod 21, stirring rod 23, scraper 24 and spiral shaft 25, thereby ensuring the heating of raw materials.

[0027] like Figure 1 As shown, the hopper 1 includes a storage end 11 and a discharge end 12 disposed at the bottom of the storage end 11;

[0028] The storage end 11 is set up to store raw materials, while the unloading end 12 is set up to provide a basis for the output of raw materials, ensuring the operation of raw material use.

[0029] like Figure 2 As shown, a spiral shaft 25 is provided on the outer surface of the lower end face of the rod 21, and the spiral shaft 25 is located inside the feeding end 12;

[0030] The spiral shaft 25 is designed to rotate synchronously with the rotation of the rod 21, and can uniformly feed the raw materials. The spiral shaft 25 also absorbs and dissipates heat due to the heating of the rod 21, thereby heating the raw materials located inside the feeding end 12. This keeps the feeding end 12 in a relatively dry environment, effectively preventing blockage caused by raw material agglomeration.

[0031] In this embodiment, the rod 21, scraper 24, and spiral shaft 25 are all made of aluminum alloy.

[0032] In this embodiment, a feed pipe 13 is provided on one side of the top of the hopper 1, and support frames 14 are provided on both sides of the bottom of the hopper 1.

[0033] The feed pipe 13 allows staff to easily inject the raw materials to be used into the silo 1, and store and transport them inside the silo 1.

[0034] In this embodiment, both the first shaft 2 and the second shaft 42 are concave.

[0035] Working principle:

[0036] First, the staff injects raw materials into the silo 1 through the feed pipe 13. After the raw materials are injected, the motor 4 drives the second shaft 42 to rotate. The rotating second shaft 42 drives the shaft, rod 21, stirring rod 23, and spiral shaft 25 to rotate via the transmission belt 43. The raw materials in the silo 1 continuously enter the rotating spiral shaft 25 and move downwards along the spiral shaft 25, thus completing the material feeding process. During the continuous feeding process, the rod 21 and stirring rod 23 agitate and crush the raw materials in the silo 1, effectively preventing the accumulation of raw materials. During the rotation of the shaft and stirring rod 23, the first heating element 3 heats the rod 21, and the heat absorbed by the rod 21 is transferred to the stirring rod 23 and the spiral shaft 25, and gradually diffuses to the surrounding area of ​​the stirring rod 23 and the spiral shaft 25, thereby completing the crushing and heating of the raw materials located in the middle of the bin 1 and inside the feeding end 12. At the same time, the heating bin 5 and the second heating element 51 can heat the raw materials located at the inner edge of the bin 1. This heating method, in combination with the heating method of the first heating element 3, can effectively achieve large-scale heating of the raw materials by the equipment itself, thereby minimizing the occurrence of raw material agglomeration.

[0037] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.

[0038] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
