Description

Technical Field

[0001] This utility model belongs to the field of mixing devices, and in particular relates to a pilot-scale mixing device for lithium mica auxiliary materials. Background Technology

[0002] A horizontal mixer is an industrial device that uses a rotating agitator inside a horizontal cylinder to uniformly mix various materials (such as powders, granules, pastes, etc.). This type of equipment is widely used in food, pharmaceutical, chemical, plastics, building materials, and feed industries, and is a key piece of equipment for material pretreatment or mixing processes in mass production. Its core function lies in utilizing the rotational motion of the horizontally placed cylinder and its internal agitation structure (such as a spiral ribbon, paddles, or plough blades) to drive the materials through complex, combined movements within the cylinder, thereby achieving thorough mixing. It features high throughput, strong adaptability, and convenient operation.

[0003] Most existing horizontal mixing equipment adopts a single stirring structure, mainly achieving material mixing through the rotation of the stirring paddle. Although such equipment has a large processing capacity, in practical applications, the mixing efficiency is still low when relying solely on the stirring paddle to agitate a large amount of material, and a long mixing time is usually required. This is especially true for mixtures of materials with large density differences, such as lithium mica raw materials, which are prone to problems such as uneven mixing and low efficiency, making it difficult to meet the requirements for uniform mixing and high efficiency.

[0004] Based on this, a pilot-scale mixing device for lithium mica auxiliary materials is provided to achieve multiple mixing modes and improve mixing efficiency. Utility Model Content

[0005] Purpose of the utility model: The technical problem to be solved by this utility model is to provide a pilot-scale mixing device for lithium mica auxiliary materials that can realize multiple mixing modes.

[0006] Technical solution: The present invention provides a pilot-scale mixing device for lithium mica auxiliary materials. The pilot-scale mixing device includes a base and a horizontal mixing box disposed on the base. A spring support assembly is provided on the base, and the horizontal mixing box is disposed on the base through the spring support assembly.

[0007] A stirring shaft is installed inside the horizontal mixing box. One end of the stirring shaft is connected to a motor, and the other end is connected to a swing shaft through a transmission gear set, so that the rotation of the swing shaft is realized by the rotation of the stirring shaft.

[0008] The other end of the swing shaft is connected to a swing arm, and the base is provided with a swing limiting elliptical ring. The swing arm passes through the swing limiting elliptical ring. Through the cooperation of the swing arm and the swing limiting elliptical ring, the horizontal mixing box can swing left and right.

[0009] Furthermore, the swing arm of the mixing pilot plant is equipped with a follower wheel, which is nested with the swing limiting elliptical ring.

[0010] Furthermore, the circumference diameter of the swing arm of the mixing pilot device is consistent with the length of the major axis of the swing limiting elliptical ring.

[0011] Furthermore, the other end of the stirring shaft of the mixing pilot device is equipped with a gear that meshes with a transmission gear set, and the swing shaft is located on the last gear of the transmission gear set.

[0012] Furthermore, the spring support assembly of the mixing pilot plant includes a support cylinder, a support rod disposed inside the support cylinder, a crescent-shaped support plate connected to the support rod, and a return spring nested on the outside of the support cylinder. The top of the return spring is in close contact with the bottom surface of the crescent-shaped support plate to support the horizontal mixing box. Moreover, there is a lateral distance between the support cylinder and the support rod to provide room for movement of the horizontal mixing box.

[0013] Furthermore, the mixing pilot plant also includes mixing box supports and material box support legs located on both sides of the base. A rotating shaft is provided between the mixing box supports, and the material box support legs are rotatably mounted on the rotating shaft to provide auxiliary support for the horizontal mixing box during loading and unloading.

[0014] Furthermore, the horizontal mixing tank of the mixing pilot device has a discharge pipe on one side of its bottom, and several mixing arms are provided on the mixing shaft.

[0015] Beneficial effects: Compared with the prior art, the advantages of this utility model are that the pilot-scale mixing device for lithium mica auxiliary materials combines stirring and oscillation to achieve efficient and uniform mixing of lithium mica raw materials and auxiliary materials, and has a reasonable structure and convenient operation.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] It should be noted that the mixing pilot plant of this utility model refers to a small-scale experimental device built after laboratory research results are obtained in order to verify the feasibility of whether the research results can achieve the technical effects on the production line.

[0023] Note: For illustrative purposes only, Figure 1 , Figure 2 and Figure 5 In the diagram, the material box support leg 4 is presented as a support. However, in actual operation, the material box support leg 4 only provides stable support during the feeding or unloading process. During the mixing process, it rotates downwards and does not provide support to prevent interference during the swaying process.

[0024] Specifically, this pilot-scale mixing device is used for mixing lepidolite as an auxiliary material, employing multiple mixing methods to achieve thorough and uniform mixing. The pilot-scale mixing device includes a base 1 and a horizontal mixing tank 2 mounted on the base 1. A discharge pipe 15 is provided on one side of the bottom of the horizontal mixing tank 2. Figure 1 and Figure 2 As shown.

[0025] like Figure 1 and 3 As shown, the base 1 has mixing tank supports 3 on both sides to support the horizontal mixing tank during loading and unloading. The mixing tank supports 3 on both sides are connected by a rotating shaft 14. The horizontal mixing tank 2 has corresponding material tank support legs 4 on both sides for movable support, and the material tank support legs 4 are connected to the rotating shaft 14. That is, the material tank support legs 4 support the horizontal mixing tank 2 during loading and unloading. During the mixing process, the material tank support legs 4 rotate to release the support of the horizontal mixing tank 2. The base 1 also has spring support assemblies at both ends of the horizontal mixing tank 2. The spring support assembly includes a support cylinder 10, a support rod 11 inside the support cylinder 10, and a crescent-shaped support plate 12 connected to the support rod 11. The crescent-shaped support plate 12 is connected to the horizontal mixing tank 2. A return spring 13 is nested on the outer side of the support cylinder 10. The top of the return spring 13 is in close contact with the bottom surface of the crescent-shaped support plate 12 to support the horizontal mixing box 2, i.e., it is supported by the return spring. The support rod 11 can move vertically up and down inside the support cylinder 10, thereby realizing the up and down movement of the horizontal mixing box 2. There is a gap between the inner wall of the support cylinder 10 and the outer side of the support rod 11, i.e., there is a lateral gap between the support cylinder 10 and the support rod 11, to provide room for the swaying of the horizontal mixing box and avoid jamming during rotation. The specific vertical movement range and lateral swaying range can be adjusted according to the actual swing range of the horizontal mixing box 2, and this utility model does not make specific limitations.

[0026] like Figure 4 As shown, the horizontal mixing tank 2 contains a stirring shaft 5 with several stirring arms 16. One end of the stirring shaft 5 is connected to a motor 6, which is mounted on the horizontal mixing tank 2. The motor 6 drives the stirring shaft 5 to rotate, thereby mixing the lithium mica auxiliary material. On the other side of the horizontal mixing tank 2 opposite to the motor 6, there is a transmission gear set, consisting of several sequentially meshing gear assemblies. The specific number can be determined according to the desired oscillation, and this invention does not impose a specific limitation. A gear is located at the end of the stirring shaft 5 furthest from the motor 6. This gear meshes with the transmission gear set, which reduces the rotational speed and increases the torque. The last gear of the transmission gear set is equipped with a swing shaft 7, which is rotated by the rotation of the stirring shaft 5. A swing arm 8 extends from the swing shaft 7. A swing limiting elliptical ring 9 is provided on the base 1 via a ring support frame 18. The swing arm 8 passes through the swing limiting elliptical ring 9. Thus, during the rotation of the swing shaft 7 to drive the swing arm 8, the swing limiting elliptical ring 9 limits the horizontal mixing tank 2 to swing along the shaft 14. Figure 5 As shown. The major axis of the swing limiting elliptical ring 9 is the same as the rotation circumference diameter of the swing arm 8, while the length of its minor axis can be designed according to the required swing amplitude. That is, during the rotation of the swing shaft 7, assuming the initial position of the swing arm 8 is at the upper vertex of the y-axis of the swing limiting elliptical ring 9, when rotating clockwise, the swing arm 8 is subjected to a downward reaction force, causing the horizontal mixing box 2 to swing to the lower right. Continuing to move, it is subjected to an upward reaction force, causing the horizontal mixing box 2 to swing upward, repeating the movement. Furthermore, there is a lateral gap between the support cylinder 10 and the support rod 11, ensuring that the horizontal mixing box 2 is not restricted during movement, leaving room for movement.

[0027] In addition, to further increase the stability of the oscillation, such as Figure 2 As shown, a follower wheel 17 can be provided on the swing arm 8, and the follower wheel 17 is nested with the swing limiting elliptical ring 9, so that rolling friction is formed between the swing arm 8 and the swing limiting elliptical ring 9, thereby improving the service life of the mixing pilot device.
