Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a cement grinding device for cement production. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder that forms a paste when mixed with water. It hardens in air or water and can firmly bind materials such as sand and stone together. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, and national defense projects. Cement grinding equipment is often used in cement production and processing. This equipment grinds cement raw materials into powder and is mainly used in cement production. The most common type is the ball mill, which grinds materials by generating friction and impact through rotation.

[0003] Conventional ball mills typically employ a horizontally mounted cylindrical structure with a large horizontal span. Structural supports are usually provided at both ends of the structure. However, this structural design means that the impact vibrations generated during the grinding and processing of materials will directly act on the middle of the cylindrical structure. Over time, this will affect the strength of the device structure and may even lead to structural deformation.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a cement grinding device for cement production. Utility Model Content

[0005] The purpose of this invention is to provide a cement grinding device for cement production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cement grinding device for cement production, comprising a grinding component and a stabilizing wheel frame. A driving mechanism is installed on one side of the grinding component, and a support shaft frame is connected to the side of the grinding component away from the driving mechanism. The stabilizing wheel frame is symmetrically installed below the grinding component. The stabilizing wheel frame includes a first shock absorber, a first support wheel, a second shock absorber, and a second support wheel. The first support wheel is mounted on the top of the first shock absorber, and the second shock absorber is connected to the side of the first shock absorber away from the grinding component. The second support wheel is mounted on the top of the second shock absorber.

[0007] Furthermore, the grinding assembly includes a ball mill body, a guide ring, and reinforcing ribs. The guide ring is distributed in the middle of the ball mill body, and reinforcing ribs are provided on the surface of the ball mill body.

[0008] Furthermore, the grinding assembly also includes a discharge gate and a bearing seat. The discharge gate is symmetrically installed on the left and right sides of the ball mill body, and bearing seats are installed on both sides of the ball mill body.

[0009] Furthermore, the guide rings are equidistantly arranged and installed in the middle section of the ball mill body, and there are three sets of them. The guide rings and the ball mill body are welded together, and the surfaces of the first support wheel and the second support wheel are both attached to the V-shaped groove structure on the surface of the guide ring.

[0010] Furthermore, the reinforcing ribs are distributed in a ring array structure on the surface of the ball mill body with the ball mill body as the center, and the reinforcing ribs are welded to the ball mill body. Moreover, the discharge gate is installed on the surface of the ball mill body through a flange structure.

[0011] Furthermore, the driving mechanism includes a support base, a drive motor, and fixed angle plates. The drive motor is mounted on the top of the support base, and fixed angle plates are connected to the lower ends of both sides of the support base.

[0012] Furthermore, the bearing housing and the ball mill body are both located on the same horizontal central axis, and the bearing housing on one side of the ball mill body is connected to the power output end of the drive motor through a coupling.

[0013] Furthermore, a fixed platform is provided at the bottom of the stabilizing wheel frame, and a base is connected to the bottom of the fixed platform. The fixed platform is symmetrically arranged at the left and right ends of the middle of the base, and the grinding assembly is horizontally mounted in the middle of the base. A feed hopper is installed on the side of the support shaft frame away from the grinding assembly, and the feed hopper is in communication with the interior of the grinding assembly.

[0014] This utility model provides a cement grinding device for cement production, which has the following beneficial effects:

[0015] 1. This utility model features three sets of stabilizing wheel frames symmetrically arranged on the left and right sides below the grinding assembly. The first and second shock absorber frames are made of damping alloy material. Due to its structural characteristic of rapidly converting vibration energy into heat energy and rapidly attenuating it, when the grinding assembly rotates axially in the horizontal direction under the drive mechanism, the internal spherical abrasives grind the material. The friction and impact force generated by the rotation are transmitted to the first and second shock absorber frames below through the first and second support wheels. This can absorb and reduce vibration as much as possible, thus avoiding unnecessary impact on the structure of the ball mill body due to long-term impact. While providing good structural support, it can also play a certain role in vibration reduction and noise reduction.

[0016] 2. This utility model, by arranging three sets of guide rings at equal intervals in the middle section of the ball mill body, and cooperating with reinforcing ribs distributed in a ring array on the surface of the ball mill body, can provide a certain degree of structural reinforcement for the horizontally mounted ball mill body. This can reduce the impact on the ball mill body itself caused by the internal spherical abrasive and the impact during the material grinding process, thus ensuring structural stability and ensuring the service life of the device. In addition, the structural connection between the first support wheel, the second support wheel and the guide rings provides good structural support, and the rotation of the first support wheel and the second support wheel can assist the rotation of the grinding components to avoid unnecessary structural interference.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3As shown, a cement grinding device for cement production includes a grinding assembly 1 and a stabilizing wheel frame 4. A drive mechanism 2 is installed on one side of the grinding assembly 1, and a support shaft frame 3 is connected to the side of the grinding assembly 1 away from the drive mechanism 2. The stabilizing wheel frame 4 is symmetrically installed below the grinding assembly 1. The stabilizing wheel frame 4 includes a first shock absorber 401, a first support wheel 402, a second shock absorber 403, and a second support wheel 404. The first support wheel 402 is mounted on the top of the first shock absorber 401, and the second shock absorber 403 is connected to the side of the first shock absorber 401 away from the grinding assembly 1. The second support wheel 404 is mounted on the top of the second shock absorber 403. The grinding assembly 1 includes a ball mill body 101, a guide ring 102, and reinforcing ribs 103. The ball mill body 101 has guide rings 102 distributed in the middle, and the surface of the ball mill body 101 is provided with reinforcing ribs 103. The grinding assembly 1 also includes a discharge gate 104 and a bearing seat 105. The discharge gates 104 are symmetrically installed on the left and right sides of the surface of the ball mill body 101, and the bearing seats 105 are installed on both sides of the ball mill body 101. The first shock absorber 401 and the second shock absorber 403 are both made of damping alloy material. Therefore, when the spherical abrasive inside the grinding assembly 1 drives the material to grind, the friction and impact force generated by the rotation will be transmitted to the first shock absorber 401 and the second shock absorber 403 below through the first support wheel 402 and the second support wheel 404, so as to absorb and reduce the vibration as much as possible.

[0023] like Figures 1 to 3As shown, guide rings 102 are equidistantly arranged in three sets in the middle section of the ball mill body 101, and the guide rings 102 and the ball mill body 101 are welded together. The surfaces of the first support wheel 402 and the second support wheel 404 are both fitted into the V-shaped groove structure on the surface of the guide rings 102. Reinforcing ribs 103 are distributed in a ring array structure around the ball mill body 101 on the surface of the ball mill body 101, and the reinforcing ribs 103 are welded together with the ball mill body 101. The discharge gate 104 is installed on the surface of the ball mill body 101 via a flange structure. The drive mechanism 2 includes a support base 201, a drive motor 202, and a fixed angle plate 203. The drive motor 202 is installed on the top of the support base 201, and fixed angle plates 203 are connected to the lower ends of both sides of the support base 201. The bearing seat 105 is connected to the ball mill body 101. All the main bodies 101 are on the same horizontal central axis, and the bearing seat 105 on one side of the ball mill main body 101 is connected to the power output end of the drive motor 202 through a coupling. The bottom of the stabilizing wheel frame 4 is provided with a fixed platform 5, and the bottom of the fixed platform 5 is connected to the base 6. The fixed platform 5 is symmetrically arranged at the left and right ends of the middle of the base 6, and the grinding component 1 is horizontally mounted in the middle of the base 6. The side of the support shaft frame 3 away from the grinding component 1 is equipped with a feed hopper 7, and the feed hopper 7 is interconnected with the interior of the grinding component 1. By arranging three sets of guide rings 102 at equal intervals in the middle section of the ball mill main body 101, and cooperating with the reinforcing ribs 103 distributed in a ring array on the surface of the ball mill main body 101, this cooperative arrangement of the structure can provide a good structural reinforcement for the horizontally mounted ball mill main body 101 to a certain extent.

[0024] In summary, as Figures 1 to 3 As shown, when using this cement grinding device for cement production, the material to be processed is first fed into the interior of the grinding assembly 1 through the feed hopper 7 on one side of the support shaft frame 3. After the material is fed in, the drive mechanism 2 on one side of the grinding assembly 1 is started. Under the operation of the drive motor 202 at the top of the support seat 201, and with the structural support of the support shaft frame 3 and the bearing seat 105, the ball mill body 101 is driven to rotate axially in the horizontal direction.

[0025] At this time, the material inside the ball mill body 101 will be ground and pulverized by the spherical abrasive, along with the rotation of the entire grinding component 1, and by the rotational friction and gravitational impact.

[0026] During this process, the stabilizing wheel frame 4 below the grinding assembly 1 will perform a structural function synchronously with the rotation of the grinding assembly 1. The first support wheel 402 and the second support wheel 404 will roll in the V-shaped groove structure of the guide ring 102 on the surface of the ball mill body 101, thereby assisting the grinding assembly 1 in structural rotation and also playing a structural support role.

[0027] During the entire grinding assembly 1 process, the vibration and impact generated by the grinding material inside will be partially transmitted to the drive mechanism 2 and support shaft frame 3 on both sides, and then transmitted to the bottom platform 6 for gradual absorption and reduction. The other part will be transmitted to the first damping frame 401 and the second damping frame 403 through the first support wheel 402 and the second support wheel 404. Utilizing the material properties, the vibration energy is converted into heat energy and rapidly attenuated. In addition, the structure of the fixed platform 5 is combined to maintain sufficient structural stability. After the processing is completed, the discharge door 104 on the surface of the ball mill body 101 can be opened to facilitate the removal of the ground material.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
