Description

Technical Field

[0001] This utility model relates to the field of screening machines, and in particular to a feldspar powder grading and screening machine. Background Technology

[0002] Feldspar powder is a powder made from aluminosilicate minerals of alkali metals or alkaline earth metals such as potassium, sodium, calcium, and barium. Its main components include silicon dioxide, aluminum oxide, potassium oxide, sodium oxide, and calcium oxide. According to different chemical compositions, feldspar powder can be divided into potassium feldspar, sodium feldspar, calcium feldspar, and barium feldspar. In the production and processing of feldspar powder, screening machines are often used to screen the particles according to the required fineness.

[0003] When the relevant screening machine is in use, as shown in the patent document with publication number CN 220406327 U, feldspar powder is usually poured into a container with a filter screen. The different particle sizes of feldspar powder can be screened and separated through the filter holes on the filter screen.

[0004] However, when using the above method, traditional screening machines often only use a single screen to screen feldspar powder. When using a single screen, due to the influence of the screen pore size, some larger feldspar powders are separated, while smaller and medium-sized feldspar powders remain in a mixed state. This often results in poor screening effect for feldspar powder. Moreover, after long-term use, the screen pores are prone to material blockage, which further reduces screening efficiency.

[0005] Therefore, it is necessary to provide a feldspar powder grading and screening machine to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 4 A feldspar powder grading and screening machine includes: a screening box 1, with a material receiving door 101 installed on the side wall of the screening box 1; and a grading and screening mechanism 2, which is located on the inner wall of the screening box 1 for grading, screening and cleaning the feldspar powder to prevent clogging.

[0022] The grading and screening mechanism 2 includes a first screen plate 201, a second screen plate 202, an anti-blocking component 3, and a driving component 4. The first screen plate 201 and the second screen plate 202 are installed on the inner wall of the screening box 1 through a vibration mechanism 6. One end of the anti-blocking component 3 is installed in the middle of the first screen plate 201 and the second screen plate 202 through the driving component 4.

[0023] The drive assembly 4 includes a motor 401, a rotating shaft 402, a first fixing block 403, and a second fixing block 404. The motor 401 is fixedly connected to the bottom center of the second screen plate 202. The rotating shaft 402 passes through the middle of the first screen plate 201 and the second screen plate 202 and is fixedly connected to the output end of the motor 401. The first fixing block 403 is fixedly connected to the middle of the rotating shaft 402, and the second fixing block 404 is fixedly connected to the top of the rotating shaft 402.

[0024] The anti-clogging component 3 includes two rotating rods 301 and two cleaning units 5. One end of each of the two rotating rods 301 is fixedly connected to the side wall of the first fixed block 403 and the side wall of the second fixed block 404, respectively. The two cleaning units 5 are respectively installed at the bottom of the two rotating rods 301.

[0025] The cleaning unit 5 includes a telescopic slide 501, a plurality of first springs 502 and an anti-clogging brush rod 503. The telescopic slide 501 is opened at the bottom of the rotating rod 301. One end of the plurality of first springs 502 is symmetrically fixedly connected to one end of the telescopic slide 501. The side wall of the anti-clogging brush rod 503 is slidably connected to the side wall of the telescopic slide 501, and the top of the anti-clogging brush rod 503 is fixedly connected to the other end of the plurality of first springs 502.

[0026] In the specific implementation process, firstly, feldspar powder is poured into the screening box 1. The powder is then graded and screened by a first screen plate 201 and a second screen plate 202 with smaller pore sizes. This allows the feldspar powder to be separated into three grades—large, medium, and small—according to the selected pore size for processing requirements. Larger pieces of feldspar powder are removed directly from the top of the screening box 1, while smaller pieces flow out directly from the bottom. The appropriately sized feldspar powder can be removed by opening the material handling door 101, which is hinged or snap-fitted on one side. Simultaneously, during the screening process, the motor 401 is activated, providing force to drive the connected rotating shaft 402 to rotate in the middle of the first and second screen plates 202. The rotation of the rotating shaft 402 causes the connected first and second fixed blocks 403 and 404 to rotate accordingly. The rotation of the rotating rods 301 causes them to rotate at the top of the first screen plate 201 and the second screen plate 202, respectively. The first spring 502 provides force, causing the anti-clogging brush rod 503 to slide out from the telescopic groove 501 at the bottom of the rotating rod 301. By sliding out of the telescopic groove 501, the anti-clogging brush rod 503 can come into contact with the surfaces of the first screen plate 201 and the second screen plate 202. At this time, the rotating rods 301... Rotating the first screen plate 201 and the second screen plate 202 causes the anti-clogging brush rod 503 to rotate under force, cleaning and preventing the feldspar powder accumulated and stuck on the surface of the first screen plate 201 and the second screen plate 202. This allows for easy grading and separation of feldspar powder according to usage needs, while also cleaning and preventing the feldspar powder accumulated and stuck in the screen filter holes. This effectively improves the screening effect of feldspar powder and avoids the situation of material blockage in the screen filter holes, thereby improving the screening efficiency.

[0027] Furthermore, the vibration mechanism 6 includes several connecting rods 601 and several buffer components 7. The middle parts of the several connecting rods 601 are evenly distributed and installed on the inner wall of the screening box 1 through several buffer components 7, and the several connecting rods 601 are evenly distributed and fixedly connected between the first screen plate 201 and the second screen plate 202.

[0028] The buffer assembly 7 includes a buffer groove 701, a support slide rod 702, a slider 703, and two second springs 704. The buffer groove 701 is formed on the inner wall of the screening box 1. The two ends of the support slide rod 702 are fixedly connected to the two ends of the buffer groove 701. The middle part of the connecting rod 601 is slidably connected to the side wall of the support slide rod 702 through the slider 703. The two ends of the two second springs 704 are fixedly connected to the two ends of the buffer groove 701 and the two ends of the slider 703, respectively.

[0029] It should be noted that the operation of the motor 401 inevitably generates vibration. This vibration drives the connected second screen plate 202 to vibrate. The vibration of the second screen plate 202, in turn, causes the first screen plate 201 to vibrate via the connecting rod 601. Simultaneously, the slider 703 in the middle of the connecting rod 601 is subjected to force, which allows it to move up and down within the buffer groove 701 supported by the support slide rod 702, compressing the second spring 704. The compression of the second spring 704 provides a reaction force to buffer the vibration force, while simultaneously increasing the amplitude of the first and second screen plates 201 and 202. This vibration of the first and second screen plates 201 and 202 allows the feldspar powder to be quickly filtered and separated. This provides vibration support for the first and second screen plates 201 and 202, thereby improving screening efficiency through vibration.

[0030] The working principle of the feldspar powder grading and screening machine provided by this utility model is as follows:

[0031] In use, feldspar powder is first poured into the screening box 1. The powder is then graded and screened by the first screen plate 201 and the second screen plate 202, which has smaller pore sizes than the first screen plate 201. This allows the feldspar powder to be separated into large, medium, and small grades according to the pore sizes selected for processing requirements. Larger feldspar powder can be removed directly from the top of the screening box 1, while smaller powder flows directly from the bottom. Medium-sized powder can be removed by opening the hinged or snap-fit ​​material gate 101 on one side. Simultaneously, during the screening process, the motor 401 is started, providing force to drive the connected rotating shaft 402, which is subjected to force on the first screen plate 201. The rotation of the middle part of the first and second screen plates 202 causes the first fixed block 403 and the second fixed block 404 connected to it to rotate. This rotation of the first fixed block 403 and the second fixed block 404 causes the two rotating rods 301 connected to them to rotate at the top of the first screen plate 201 and the second screen plate 202, respectively. The first spring 502 provides force, causing the anti-clogging brush rod 503 connected to it to slide out from the telescopic groove 501 at the bottom of the rotating rod 301. By sliding out from the telescopic groove 501, the anti-clogging brush rod 503 can fit against the surface of the first screen plate 201 and the second screen plate 202. At this time, the rotating rod 301... 01. Rotating the first screen plate 201 and the second screen plate 202 respectively will cause the anti-clogging brush rod 503 to rotate under force, cleaning and preventing the feldspar powder accumulated and stuck on the surfaces of the first screen plate 201 and the second screen plate 202. This achieves the goal of effectively grading and separating feldspar powder according to usage needs, while also cleaning and preventing the feldspar powder accumulated and stuck in the screen filter holes, thereby effectively improving the screening effect of feldspar powder and avoiding the situation of material blockage in the screen filter holes, thus improving the screening efficiency. Secondly, the motor 401 will inevitably generate vibration when it starts running. The vibration generated by the motor 401 will cause the connected second screen plate 202 to vibrate under force. 2. Vibration allows the connecting rod 601 to drive the first screen plate 201 to vibrate. Simultaneously, the slider 703 in the middle of the connecting rod 601 is subjected to force, which allows it to move up and down within the buffer groove 701 supported by the support slide rod 702 and to compress the second spring 704 back and forth. The compression of the second spring 704 provides a reaction force to rebound and buffer the vibration force. At the same time, the rebound force increases the amplitude of the first screen plate 201 and the second screen plate 202. Thus, the vibration of the first screen plate 201 and the second screen plate 202 allows the feldspar powder to be quickly filtered and separated during vibration. This effectively provides vibration support for the first screen plate 201 and the second screen plate 202, thereby facilitating further improvement of screening efficiency through vibration.
