Description

Technical Field

[0001] The utility model relates to the technical field of premixing equipment, in particular to a premixing mechanism of a ball mill. Background Art

[0002] The ball mill for ceramic particle processing is a device specially used for processing ceramic particles. It grinds and mixes ceramic raw materials by ball milling. Traditional ceramic particle processing ball mills usually mix raw materials during the ball grinding process, but this mixing method is often not uniform and efficient enough, especially when it is necessary to add a variety of raw materials of different properties. All the raw materials are directly added to the ball mill at one time, resulting in a long mixing time and low efficiency. Utility Model Content

[0003] The utility model aims to provide a pre-mixing mechanism for a ball mill to solve the problem in the background art that the ball mill for processing ceramic particles directly adds all raw materials into the ball mill at one time, resulting in a long mixing time and low efficiency.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A coaxially arranged servo motor is installed at the end of each group of the feeding pipes away from the premixing pipe, and a spiral feeding rod is connected to the output shaft of the servo motor;

[0007] A plug-in tube which is plugged and matched with the feeding tube is installed at the bottom of the second feeding hopper.

[0013] Preferably, a feed control valve for controlling start and stop and feed speed is installed on each group of the plug-in pipes.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] In the premixing mechanism of the ball mill, by installing several groups of feeding tubes on the outer wall of the premixing tube, different kinds of raw materials can be added to the premixing tube at the same time. Each group of feeding tubes is independently controlled, and the addition ratio and speed of various raw materials can be adjusted as needed, realizing flexible and accurate raw material mixing. The servo motor installed at the end of each group of feeding tubes away from the premixing tube provides stable and reliable power for the spiral feeding rod. The precise control of the servo motor allows the speed and rotation direction of the spiral feeding rod to be flexibly adjusted, further improving the mixing effect and uniformity of the raw materials. The design of the second feed hopper allows the raw materials to be easily added to the feeding tube. The plug-in connection between the plug-in tube and the feeding tube ensures the sealing and stability of the raw materials during the transportation process, avoiding leakage and waste of raw materials.

[0029] A premixing mechanism of a ball mill, such as Figure 1-Figure 3As shown, it includes a vertical ball mill 20 and a premixing tube 10 installed on the vertical ball mill 20, a plurality of feeding tubes 30 for adding different raw materials are installed on the outer wall of the premixing tube 10, and a second feeding hopper 40 is installed at the top of the outer wall of each feeding tube 30 away from the premixing tube 10; a coaxially arranged servo motor 31 is installed at the end of each feeding tube 30 away from the premixing tube 10, and a spiral feeding rod 32 is connected to the output shaft of the servo motor 31; a second feeding hopper 40 is installed at the bottom There is a plug-in tube 41 that plugs with the feed tube 30. By installing several groups of feed tubes 30 on the outer wall of the premixing tube 10, different kinds of raw materials can be added to the premixing tube 10 at the same time. Each group of feed tubes 30 is independently controlled, and the addition ratio and speed of various raw materials can be adjusted as needed, realizing flexible and accurate raw material mixing. The servo motor 31 installed at the end of each group of feed tubes 30 away from the premixing tube 10 provides stable and reliable power for the spiral feed rod 32. The precise control of the servo motor allows the speed and rotation direction of the spiral feed rod 32 to be flexibly adjusted, further improving the mixing effect and uniformity of the raw materials. The design of the second feed hopper 40 allows the raw materials to be easily added to the feed tube 30. The plug-in cooperation of the plug-in tube 41 and the feed tube 30 ensures the sealing and stability of the raw materials during the transportation process, avoiding leakage and waste of raw materials.

[0030] Furthermore, a top box 11 is installed on the top of the premixing tube 10, and a vibration motor 12 is installed in the top box 11 to achieve vibration mixing of the raw materials in the premixing tube 10. This design helps to accelerate the contact and mixing between the raw materials, so that different raw materials can be mixed more quickly and evenly, and the mixing efficiency is improved.

[0031] Among them, a first feed hopper 21 is arranged on the top of the vertical ball mill 20, and the bottom of the feed pipe 30 is plugged into the top of the first feed hopper 21 for easy installation or disassembly, ensuring that the pre-mixed raw materials can smoothly and accurately enter the ball mill for further processing.

[0032] It is worth noting that the number of the feeding tubes 30 is 2-4 groups, which not only ensures the diversity of raw material mixing, but also avoids the complexity of the structure and the occupation of space caused by too many feeding tubes.

[0033] Specifically, a connecting plate 33 is coaxially installed at one end of each group of feeding pipes 30 connected to the pre-mixing pipe 10. The connecting plate 33 is installed on the outer wall of the pre-mixing pipe 10 by at least three groups of fixing bolts 34, which is convenient for installation or disassembly. At the same time, it also makes the connection between the feeding pipe 30 and the pre-mixing pipe 10 stable and reliable, avoiding leakage or loosening that may occur during the raw material transportation process.

[0034] In addition, a feed control valve 42 for controlling the start and stop and feeding speed is installed on each group of plug-in tubes 41, so that the user can conveniently control the start and stop and feeding speed of each group of feeding tubes 30, which not only improves the flexibility of operation, but also helps to accurately adjust the mixing ratio and speed of raw materials according to production needs.

[0035] The working principle of the pre-mixing mechanism of the ball mill is as follows: the operator puts different kinds of raw materials into each second feed hopper 40 according to production needs, starts the vertical ball mill 20, provides a mixing environment for the pre-mixing tube 10, and starts and adjusts the servo motor 31 at the end of each group of feeding tubes 30 as needed, so that it works at an appropriate speed and direction of rotation. When the servo motor 31 is started, the spiral feed rod 32 starts to rotate, and the raw materials in the second feed hopper 40 are transported to the pre-mixing tube 10 through the feeding tube 30. The servo motor 31 of each group of feeding tubes 30 can be independently controlled as needed to adjust the addition ratio and speed of different raw materials and mix them at a uniform speed.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
