Description

Technical Field

[0001] This solution belongs to the field of air classifier equipment, specifically involving an air classifier with an anti-clogging structure. Background Technology

[0002] In the cement production process, the air classifier is one of the key pieces of equipment in the grinding system. It is mainly used to classify the ground cement particles according to their particle size. Qualified fine powder is collected as finished product, while coarse powder is returned to the mill for re-grinding.

[0003] A search revealed that in the invention patent application with publication number CN111495497A, a classifier for cement preparation is disclosed, comprising a housing, a feeding pipe, a support frame fixedly installed in the inner cavity of the housing, a motor fixedly installed on the top surface of the housing, a main shaft fixedly sleeved at the output end of the motor, a grinding plate and a screen movably sleeved on the surface of the main shaft, and guide blocks fixedly installed on the side walls of both the grinding plate and the screen.

[0004] Traditional air classifiers often face the following problems in actual operation: 1. Clay powder is prone to moisture and clumping, or it may form a "block" in the feed pipe due to poor flowability during the conveying process, resulting in poor feeding and affecting the sorting efficiency; 2. Fine powder is prone to adhering to the screen inside the air classifier during the sorting process, and long-term accumulation will block the mesh. Utility Model Content

[0005] The purpose of this solution is to provide a classifier with an anti-clogging structure to solve the problem of easy clogging of the feed inlet and screen in existing technologies.

[0006] To achieve the above objectives, this solution provides a classifier with an anti-clogging structure, comprising an upper shell and a lower shell. Two connecting frames are fixedly connected to the exterior of both the upper and lower shells. A rotating ring is rotatably connected between the upper and lower shells. A filter screen is fixedly connected to the inner wall of the rotating ring. A protrusion is fixedly connected to the upper right side of the filter screen. A motor is fixedly mounted on the top of the upper shell. The output shaft of the motor passes through the upper shell and is connected to it via a bearing. A rotating shaft is fixedly connected to the end of the output shaft. A striking rod is fixedly connected to the upper section of the rotating shaft. A connecting rod is fixedly connected to the middle section of the rotating shaft. A sliding pin is slidably connected to the end of the connecting rod. A dispersing plate is fixedly connected to the end of the sliding pin. The dispersing plate abuts against the filter screen. The position of the dispersing plate corresponds to the protrusion. A feed pipe is connected to the top of the upper shell, and an anti-clogging mechanism is provided inside the feed pipe.

[0007] The principle of this solution is as follows: In use, the raw material powder after ball milling is first conveyed through the feed pipe to the space between the upper and lower shells. Then, it is filtered through the filter screen for further separation. At the same time, the motor drives the rotating shaft to rotate, which in turn drives the impact rod to periodically strike the sliding rod, forcing the arch-breaking cone to move up and down, instantly breaking the material arch and preventing blockage of the feed pipe. Meanwhile, the dispersing plate is always in close contact with the filter screen through the elastic pressure of the spring, and the rotating shaft drives it to rotate at high speed, periodically colliding with the protrusions on the filter screen, causing the filter screen to vibrate, thereby effectively preventing the mesh from clogging and further improving the efficiency of powder selection.

[0008] The technical effect of this solution is that by working together with the innovative unblocking and anti-blocking mechanism and the electric motor-driven impact rod, the anti-blocking efficiency is improved and the blockage of the feed pipe is prevented. Specifically, when the material forms an arch in the feed pipe, the rotating shaft drives the impact rod to periodically strike the slide rod, forcing the arch-breaking cone to move up and down, instantly breaking the material arch.

[0009] The dispersing plate is kept in close contact with the filter screen by the elastic pressure of the spring, while the rotating shaft drives it to rotate at high speed and periodically collide with the protrusions on the filter screen, causing the filter screen to vibrate, thereby effectively preventing the mesh from clogging and further improving the efficiency of powder selection.

[0010] Furthermore, both the upper and lower ends of the rotating ring are fixedly connected to protruding pins. The two protruding pins are rotatably connected to the upper and lower housings, respectively. A U-shaped pin is rotatably connected to the inside of the left side wall of the upper housing. A connecting block is fixedly connected to the U-shaped pin, and a rubber retaining bead is fixedly connected to the connecting block. The rubber retaining bead engages with the outer ring wall of the rotating ring. The rotating ring can rotate around the protruding pins as its axis, thereby removing large particles of powder filtered by the filter screen from the upper and lower housings. Simultaneously, the rubber retaining bead helps to fix the installation position of the rotating ring.

[0011] Furthermore, a square rod is fixedly connected to the top of the sliding pin, and the square rod is slidably connected to the connecting rod. A spring is sleeved on the outer side of the square rod, one end of which is fixedly connected to the sliding pin, and the other end of which is fixedly connected to the inner surface of the connecting rod. The square rod and spring provide guidance and auxiliary resetting for the extension and retraction of the sliding pin and the dispersion plate.

[0012] Furthermore, a discharge port is provided at the bottom of the lower housing, and a discharge ramp is fixedly connected to the bottom of the lower housing, with the position of the discharge ramp corresponding to the discharge port. The discharge ramp facilitates the discharge of fine materials.

[0013] Furthermore, the unblocking and anti-clogging mechanism includes two fixed rods fixedly connected to the inner wall of the feed pipe, with a fixed block fixedly connected between the two rods. A sliding rod is slidably connected inside the fixed block, and the sliding rod penetrates the fixed block. The lower end of the sliding rod corresponds to the end of the impact rod, and a breaking cone is fixedly connected to the upper end of the sliding rod. Through the design of the unblocking and anti-clogging mechanism, in conjunction with the impact rod, it effectively unblocks the feed pipe.

[0014] Furthermore, a second spring is fitted onto the outer side of the sliding rod. One end of the second spring is fixedly connected to the arch-breaking cone, and the other end is fixedly connected to the fixing block. The second spring provides auxiliary repositioning for both the arch-breaking cone and the sliding rod.

[0015] Furthermore, a protective sleeve is fixedly connected to the upper end of the fixing block, and the top of the protective sleeve is fixedly connected to the arch-breaking cone. The protective sleeve provides protection for the second spring. Attached Figure Description

The square rod 16 and the spring 17 guide and assist in the retraction and resetting of the sliding pin 14 and the dispersing plate 15.

[0025] like Figure 2 , Figure 5 , Figure 6 As shown, both the upper and lower ends of the rotating ring 9 are fixedly connected to protruding pins 11. The two protruding pins 11 are rotatably connected to the upper housing 1 and the lower housing 2, respectively. A protruding pin 18 is rotatably connected inside the left side wall of the upper housing 1. A connecting block 19 is fixedly connected to the protruding pin 18, and a rubber bead 20 is fixedly connected to the connecting block 19. The rubber bead 20 engages with the outer ring wall of the rotating ring 9. The rotating ring 9 can rotate around the protruding pins 11, thereby removing large particles of powder filtered by the filter screen 10 from the upper housing 1 and the lower housing 2. Simultaneously, the rubber bead 20 helps to fix the installation position of the rotating ring 9. A discharge port is provided at the bottom of the lower housing 2, and a discharge ramp 21 is fixedly connected to the bottom of the lower housing 2, with the position of the discharge ramp 21 corresponding to the discharge port. The discharge ramp 21 facilitates the discharge of fine materials.

[0026] like Figure 2 , Figure 4As shown, an inlet pipe 7 is connected to the top of the upper housing 1. An anti-blocking mechanism 8 is installed inside the inlet pipe 7. This mechanism, in conjunction with the impact rod 6, unblocks the inlet pipe 7. The anti-blocking mechanism 8 includes two fixed rods 81 fixedly connected to the inner wall of the inlet pipe 7. A fixed block 82 is fixedly connected between the two fixed rods 81. A sliding rod 83 is slidably connected inside the fixed block 82, and the sliding rod 83 penetrates through the fixed block 82. The lower end of the sliding rod 83 corresponds to the end of the impact rod 6, and a breaking cone 84 is fixedly connected to the upper end of the sliding rod 83. A second spring 85 is sleeved on the outer side of the sliding rod 83.

The protective sleeve 86 provides protection for the second spring 85.

[0027] The specific implementation process of this utility model is as follows: In use, firstly, the raw material powder after ball milling is conveyed through the feed pipe 7 to the space between the upper shell 1 and the lower shell 2. Then, it is further subdivided after being filtered by the filter screen 10. At the same time, the motor 4 drives the rotating shaft 5 to rotate, which in turn drives the impact rod 6 to periodically impact the sliding rod 83, forcing the arch-breaking cone 84 to move up and down, instantly breaking the material arch and preventing blockage of the feed pipe 7. Meanwhile, the dispersing plate 15 is always in close contact with the filter screen 10 due to the elastic pressure of the spring 17, and the rotating shaft 5 drives it to rotate at high speed, periodically colliding with the protrusions 12 on the filter screen 10.

[0028] This solution improves anti-blocking efficiency and prevents blockage of the feed pipe 7 by working in conjunction with an innovative unblocking and anti-clogging mechanism 8 and a striker 6 driven by a motor 4. When material forms an arch in the feed pipe 7, the rotating shaft 5 drives the striker 6 to periodically impact the slide bar 83, forcing the arch-breaking cone 84 to move up and down, instantly breaking the material arch. The dispersing plate 15 is always in close contact with the filter screen 10 by the elastic pressure of the spring 17, while the rotating shaft 5 drives it to rotate at high speed and periodically collide with the protrusions 12 on the filter screen 10, causing the filter screen 10 to vibrate, thereby effectively preventing the mesh from clogging and further improving the efficiency of powder selection.
