Description

Technical Field

[0001] This utility model belongs to the field of classification equipment technology, specifically relating to an automatic classification device for grinding media. Background Technology

[0002] In the processing of vanadium-titanium magnetite, the quality and particle size distribution of grinding media have a crucial impact on the production process and product quality. Appropriate grinding media particle size can improve grinding efficiency, reduce energy consumption, and enhance product uniformity and quality. Therefore, accurate and efficient classification of grinding media is an indispensable key step in the production process.

[0003] Traditional grinding media classification equipment often only achieves relatively coarse classification accuracy. Due to the fixed screen aperture and limited number of classification stages, it is difficult to perform multi-stage subdivision to meet the precise particle size requirements of grinding media according to different production needs. This results in a wide particle size distribution range after classification, which cannot meet the requirements of some production processes with strict particle size requirements, thus affecting the quality of the final product. Therefore, this application proposes an automatic grinding media classification device. Utility Model Content

[0004] The purpose of this invention is to provide an automatic classification device for grinding media, which adopts a circumferential oscillating screening method, thereby accelerating the screening process of grinding media and greatly improving the classification efficiency. Compared with the traditional static screening method, it can complete the classification of grinding media in a shorter time.

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: An automatic grading device for grinding media includes a ring plate, a bottom box suspended on the top of the ring plate, multiple grading boxes stacked on top of the bottom box, a screening screen on the bottom wall of each grading box, and a discharge port on the side wall of each grading box and the bottom box. A driving mechanism is provided at the bottom of the ring plate, the driving mechanism including a motor and a cam. The motor is located at the bottom of the ring plate and is vertically oriented upwards. The cam is radially mounted on the output shaft of the motor, and the other end of the cam is rotatably connected to the center of the bottom of the bottom box.

[0006] Furthermore, a ball support is provided on the upper surface of the ring plate, and a ball is movably embedded in the ball support, with the lower surface of the bottom box in rolling contact with the ball.

[0007] Furthermore, multiple ball supports are provided, and the multiple ball supports are arranged in a ring around the connecting shaft of the base box and the cam, with a ball movably embedded in each ball support.

[0008] Furthermore, a base plate is provided at the bottom of the ring plate, the base plate and the ring plate are distributed in parallel, and multiple columns are vertically fixed between the base plate and the ring plate, and the motor is fixed on the base plate.

[0009] Furthermore, the top of the bottom box is equipped with a top cover, and the top cover has a feed inlet in the center.

[0010] Furthermore, each of the grading boxes is provided with a first ear plate at the bottom of its side wall and on the side wall of its top cover, and a second ear plate is provided at the top of each of the grading boxes' side wall and the top of its bottom side wall. A vertical insertion post is provided at the bottom of the first ear plate, and the insertion post is inserted into the second ear plate.

[0011] Furthermore, each of the grading boxes is provided with a base plate at the bottom, which can be embedded in the grading box and the bottom box below. The bottom wall of the base plate has a downward slope on the side away from the discharge port, and a discharge port is opened on the side of the bottom wall of the base plate away from the discharge port. A retaining ring is provided at the bottom of the grading box, and the screening screen is assembled on the retaining ring.

[0012] Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a drive mechanism to propel the bottom box and classifier box in a circular oscillating motion, causing the grinding media to continuously roll within the device. This accelerates the screening process and significantly improves classification efficiency. Compared to traditional static screening methods, it can complete the classification of grinding media in a shorter time. Furthermore, the ball supports and ball design on the ring plate greatly reduce the friction between the bottom box and the ring plate during vibration, resulting in smoother vibration of the bottom box, reduced wear and noise, and extended service life of the device.

[0013] In this invention, each classifier box has a screening screen on its bottom wall, and multiple classifier boxes are stacked together. Screens with different apertures can be set according to different particle size requirements to achieve multi-level precise classification of grinding media and meet the particle size requirements of grinding media in different production processes. Each classifier box is connected together by the insertion of inserts and ear plates. The chassis is embedded in the classifier box or bottom box below, and the number of classifier boxes can be increased or decreased as needed.

[0014] In this invention, by setting up a chassis, during the grinding media screening process, the grinding media passing through the screening screen can fall from the material outlet along the slope of the chassis into the lower classification box or bottom box for further screening, thereby extending the classification path of the grinding media and improving the classification effect.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-6As shown, this embodiment provides an automatic grading device for grinding media, including a base plate 1, a ring plate 2, a bottom box 4, a grading box 5, a screening screen 9, a drive mechanism 10, and a ball 20. The base plate 1 is located below the ring plate 2, and the base plate 1 and the ring plate 2 are arranged in parallel. The base plate 1 and the ring plate 2 are connected by multiple vertically fixed columns 3, which are evenly distributed between the base plate 1 and the ring plate 2 to provide stable support for the ring plate 2. The bottom box 4 is suspended above the top of the ring plate 2, and the drive mechanism 10 is located at the bottom of the ring plate 2. The drive mechanism 10 includes a motor 14 and a cam 15. The motor 14 is fixedly mounted on the base plate 1, and the cam 15 is radially mounted on the output shaft of the motor 14. The other end of the cam 15 is rotatably connected to the bottom center of the bottom of the bottom box 4. When the motor 14 is started, it drives the cam 15 to rotate, and the rotation of the cam 15 causes the bottom box 4 to produce a circular oscillating motion.

[0020] Furthermore, the upper surface of the ring plate 2 is provided with multiple ball supports 19, which are arranged in a ring around the connecting shaft between the base box 4 and the cam 15. Each ball support 19 is movably fitted with a ball 20, and the lower surface of the base box 4 makes rolling contact with the ball 20. In this way, during the circumferential oscillation of the base box 4, the ball 20 rolls within the ball support 19, reducing the friction between the base box 4 and the ring plate 2, making the circumferential oscillation of the base box 4 smoother, and ensuring the stability of the base box 4.

[0021] Furthermore, multiple grading boxes 5 are stacked on top of the bottom box 4. Each grading box 5 has a screening screen 9 on its bottom wall. The screening screen 9 is mounted on the retaining ring 13 at the bottom of the grading box 5. The mesh size of the screening screen 9 in the multiple grading boxes 5 gradually increases from top to bottom. Each grading box 5 and the side wall of the bottom box 4 are provided with a discharge port 6 for discharging the grinding media after screening.

[0022] Furthermore, the topmost grading box 5 is covered with a top cover 7, and a feed inlet 8 is located in the center of the top cover 7, through which the grinding media enters the device. Each grading box 5 has a first ear plate 16 at the bottom of its side wall and on the side wall of the top cover 7, and each grading box 5 has a second ear plate 17 at the top of its side wall and on the top of the side wall of the bottom box 4. A vertical insertion post 18 is installed at the bottom of the first ear plate 16, and the insertion post 18 is inserted into the second ear plate 17. Through this insertion method, each grading box 5 and the top cover 7 are sequentially spliced ​​onto the bottom box 4 to form an integrated grading structure.

[0023] Furthermore, each grading box 5 is equipped with a base plate 11 at its bottom. The base plate 11 can be embedded in the grading box 5 and the bottom box 4 located below, serving to position and stabilize the grading box 5. The bottom wall of the base plate 11 has a downward slope on the side away from the discharge port 6, and a discharge port 12 is opened on the side of the bottom wall of the base plate 11 away from the discharge port 6. In this way, during the screening of grinding media, the grinding media passing through the screening screen 9 can fall from the bottom plate 11 along the slope from the discharge port 12 into the grading box 5 or the bottom box 4 below for further screening.

[0024] Working principle: When it is necessary to classify the grinding media, the grinding media is first poured into the device through the feed port 8 on the top cover 7, and the grinding media falls into the uppermost classification box 5. The motor 14 in the drive mechanism 10 is started, and the motor 14 drives the cam 15 to rotate. The rotation of the cam 15 causes the bottom box 4 to produce a circular oscillating motion. Since each classification box 5 is spliced ​​together with the bottom box 4 through the insertion and engagement of the insert post 18 and the ear plate, and the bottom box 4 is in rolling contact with the ball 20, the bottom box 4 will drive the entire classification box 5 to oscillate together.

[0025] During the circular oscillation motion, the grinding media continuously rolls within the classifier 5. Smaller grinding media particles fall through the screening mesh 9 on the bottom wall of the classifier 5 into the lower classifier 5 or the bottom classifier 4, while larger grinding media particles remain in the current classifier 5. As the vibration continues, the grinding media of different particle sizes gradually separate within the classifiers 5. After the grinding media has been screened, grinding media of different particle sizes remain in different classifiers 5 and bottom classifiers 4, respectively. By opening the discharge ports 6 on the side walls of each classifier 5 and bottom classifier 4, grinding media of different particle sizes can be discharged separately, achieving automatic classification of the grinding media.

[0026] All technical features in this embodiment can be freely combined according to actual needs.

[0027] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
