Description

Technical Field

[0001] This utility model relates to the technical field of mica production equipment, and in particular to a multi-layer roller mill for mica production. Background Technology

[0002] Synthetic mica is a layered silicate compound formed from chemical raw materials and high-quality mineral raw materials through high-temperature reaction, melting, cooling, crystallization, and growth. It has the following characteristics: it does not contain hydrocarbon groups, so it has better temperature resistance and good insulation properties. At the same time, since this compound is formed by direct firing, it has high purity and whiteness. It is widely used in industries such as pearl pigments, cosmetic powders, plastics and ceramic fillers. In addition, due to the excellent electrical insulation properties of mica, it is also widely used in electrical insulation and electronics industries, such as the artificial crystal mica sheets used in high-speed rail infrastructure insulation components.

[0003] After coarse crushing, mineral raw materials containing mica need to undergo further stratified crushing. One method of stratified crushing is using a roller mill. However, the production efficiency of existing roller mills is generally low. One reason for this is that during the roller milling process, after the mineral raw materials are crushed, they still need to be roller milled together with the uncrushed parts until all minerals have been roller milled.

[0004] In view of this, there is an urgent need for a multi-layer roller mill for mica production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer roller mill for mica production that solves the above-mentioned problems.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see the appendix Figure 1-5 A multi-layer milling machine for mica production, comprising:

[0025] The assembly comprises a housing 1, a support frame 2, a motor 3, a rotating shaft 4, and at least two sets of grinding wheel assemblies 5. The support frame 2 is fixedly connected to the bottom plate of the housing 1, and the motor 3 is fixedly connected to the support frame 2. The housing 1 is provided with multiple partition plates 13 that divide it into an upper chamber 10, a middle chamber 11, and a lower chamber 12. The partition plates 13 are provided with multiple discharge holes 130. The two sets of grinding wheel assemblies 5 are respectively located in the upper chamber 10 and the middle chamber 11. One end of the rotating shaft 4 passes through multiple partition plates 13 and is connected to the top plate of the housing 1 by a bearing. The other end passes through the bottom plate of the housing 1 and is connected to the motor 3. The rotating shaft 4 is fixedly connected to the grinding wheel assembly 5.

[0026] The outer casing 1 is divided into multiple grinding chambers by a partition plate 13, and grinding wheel assemblies 5 are installed in different chambers. The multiple grinding wheel assemblies 5 are driven simultaneously by a rotating shaft 4. During the grinding process, the grinding wheel assembly 5 in the upper chamber 10 grinds the mica raw material into particles of a certain size. The particles can then enter the middle chamber 12 through the discharge hole 130. After further grinding in the grinding wheel assembly 5, the mica raw material becomes the required powder and enters the lower chamber 12 through the discharge hole 130 on the partition plate 13 at the bottom of the middle chamber 11. This allows the staff to directly remove the powdered mica raw material from the lower chamber 12.

[0027] Specifically, the support frame 2 includes a placement plate 20 and multiple support legs 21. One end of each support leg 21 is fixedly connected to the bottom of the outer shell 1, and the placement plate 20 is fixedly connected to the middle position of the multiple support legs 21. The motor 3 is detachably connected to the placement plate 20. In order to facilitate feeding and unloading, the support frame 2 is used to raise the overall position, and the motor 3 is set on the placement plate 20 to avoid conflict between the installation of the motor 3 and the feeding pipe.

[0028] Specifically, the grinding wheel assembly 5 includes a connecting cylinder 50, at least two connecting rods 51, at least two sets of grinding wheels 52, and multiple mixing plates 53. The connecting cylinder 50 is keyed to the rotating shaft 4. One end of each of the two connecting rods 51 is symmetrically fixed to the curved sidewall of the connecting cylinder 50, and the other end is connected to the bearing of the grinding wheel 52. The multiple mixing plates 53 are evenly distributed between the two connecting rods 51, and one end of each mixing plate 53 is fixedly fixed to the curved sidewall of the connecting cylinder 50. The connection between the connecting cylinder 50 and the rotating shaft 4 enables driving, thereby achieving… The rotation of the entire grinding wheel assembly 5 drives the flow-through grinding wheel 52 to grind the raw materials. The presence of at least two sets of grinding wheels 52 not only accelerates the grinding rate of the raw materials and improves production efficiency, but also makes the structure of the two sets of grinding wheels 52 more stable, reducing the likelihood of cracking at the connection between the connecting rod 51 and the connecting cylinder 50. Considering that the running trajectory of the grinding wheel 52 is singular, some raw materials may remain outside the running trajectory of the grinding wheel 52 and fail to be ground. Therefore, a rake-shaped material plate 53 is set between the two sets of grinding wheels 52 to agitate the raw materials in the chamber.

[0029] Specifically, the mixing plate 53 is rake-shaped, and the rake teeth of two symmetrical mixing plates 53 are interlaced; in order to enhance the use effect of the mixing plate 53, different mixing plates 53 have different rake shapes to reduce the probability of dead corners in the chamber.

[0030] Specifically, the partition plate 13 is equipped with a matching material hole adjustment assembly 6. The material hole adjustment assembly 6 includes a circular plate 60, a penetrating plate 61, an arc-shaped locking plate 63, and a locking screw 62. The circular plate 60 is rotatably connected to the partition plate 13, and the circular plate 60 is provided with an adjustment hole 600 corresponding to the position of the material discharge hole 130. The curved side wall of the outer shell 1 is provided with an arc-shaped adjustment hole 15. One end of the penetrating plate 61 is fixedly connected to the circular plate 60, and the other end passes through the arc-shaped adjustment hole 15 and is fixedly connected to the arc-shaped locking plate 63. One end of the locking screw 62 passes through the arc-shaped locking plate 63 and contacts the curved side wall of the outer shell 1, and the locking screw 62 is threadedly connected to the arc-shaped locking plate 63. Considering practical applications, Depending on the quantity of material milled per cycle and the content of raw minerals, there may be variations in the required size of the discharge hole 130. To facilitate adjustment of the discharge hole 130, a discharge hole adjustment component 6 is provided. This component uses a central plate 60 that matches the partition plate 13. The overlapping portion of the adjustment hole 600 on the central plate 60 and the discharge hole 130 forms the actual discharge channel. When discharge hole adjustment is required, the locking screw 62 is removed, disengaging it from the outer casing 1. Then, the arc-shaped locking plate 63 and the penetrating plate 13 directly rotate the central plate 60 within the outer casing 1, thereby adjusting the size of the overlapping portion of the adjustment hole 600 and the discharge hole 130. It should be noted that, to clearly define the position and relationship between the discharge hole 130 and the adjustment hole 600, the following is provided: Figure 1 The feed hole 130 and the adjustment hole 600 in the middle have been appropriately enlarged. In practical applications, the sizes of the two feed holes are much smaller than those in the attached... Figure 1 As shown in the image.

[0031] Specifically, the circular plate 60 has an annular protrusion 601 fixedly connected to the partition plate 13 on the side near the partition plate 13. The bottom wall of the partition plate 13 has an annular T-groove 131 that matches the annular protrusion 601. The annular protrusion 601 is slidably connected in the annular T-groove 131. In order to achieve relative rotation between the circular plate 60 and the partition plate 13, a clearance fit is adopted between the annular protrusion 601 and the annular T-groove 131. This method can not only satisfy the relative rotation between the circular plate 60 and the partition plate 13, but also avoid the problem of edge deformation of the circular plate 60.

[0032] Specifically, the curved sidewall of the outer shell 1 is provided with a plurality of position marking holes 16 that match the locking screw 62, and the position marking holes 16 are provided with hole diameter marking scales; in order to facilitate the adjustment of the overlapping part of the adjustment hole 600 and the feeding hole 130, a plurality of position marking holes 16 with hole diameter marking scales are provided on the outer shell 1. During adjustment, it is only necessary to ensure that the locking screw 62 can enter the corresponding position marking hole 16 to complete the adjustment of the actual feeding hole diameter.

[0033] Specifically, the top wall of the outer shell 1 is provided with a filling port 17, the side wall of the lower cavity 12 is provided with a discharge port 120, and the lower cavity 12 is provided with a trapezoidal frustum 121.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
