Description

Technical Field

[0001] The utility model relates to the technical field of magnesium powder screening equipment, in particular to a vibrating screen for preventing blockage of finished magnesium powder feeding. Background Art

[0002] Vibrating screen is a device that uses the principle of vibration to screen materials. It is widely used in mining, metallurgy, chemical industry, building materials, food and other industries. The working principle of the vibrating screen is to vibrate the screen frame through the exciting force generated by vibration. The material on the screen frame is affected by the inertial force and moves forward or outward. At the same time, material particles smaller than the size of the screen hole fall into the lower layer through the screen hole, while large particles are discharged from different outlets to achieve screening and classification.

[0003] When the vibrating screen is used to screen finished magnesium powder, the holes on the screen frame of the vibrating screen are relatively small, and a portion of slightly larger magnesium powder particles may enter the holes and fail to fall down. At the same time, the large particles of magnesium powder cannot move, causing the holes on the screen frame to be blocked. In order to solve this technical problem, the utility model proposes a vibrating screen for preventing the finished magnesium powder from being discharged and blocked. Utility Model Content

[0014] In the utility model, through the cooperation between the first motor, the sliding seat and the brush, the rotation of the first motor can provide power, and the rotation power is transmitted to the brush through the rotating rod, driving the brush to rotate. The rotation of the brush can clean out large particles stuck in the screen frame with magnesium powder, so as to avoid the large particles clogging the holes on the screen frame, causing small particles to be unable to pass through the holes on the screen frame, thereby reducing the screening efficiency of the vibrating screen. The large particles of magnesium powder stuck in are cleaned out by the brush, thereby improving the screening efficiency of the vibrating screen.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a vibrating screen for preventing blockage of finished magnesium powder feeding includes a base 1, one end of the base 1 is connected to a plurality of springs 2, the other ends of the plurality of springs 2 are connected to a bottom frame 3, the plurality of springs 2 are arranged in a circular array, the lower surface of the bottom frame 3 is connected to a plurality of sleeves 10, the plurality of sleeves 10 are all located outside the spring 2, one end of the base 1 is connected to a plurality of sleeves 2 11, the plurality of sleeves 2 11 are all located outside the spring 2, when the vibrating screen vibrates, shaking will occur between the base 1 and the bottom frame 3, and the spring 2 will be driven to shake at the same time, the sleeves 10 and the sleeves 11 can prevent the spring 2 from moving, and the stability of the spring 2 can be maintained by the sleeves 10 and the sleeves 11.

[0024] One end of the bottom frame 3 is detachably connected to a screen frame 4, and magnesium powder is screened through the tiny holes on the screen frame 4. The upper surface of the bottom frame 3 is connected to a support frame 5, and a slide seat 6 is arranged inside the support frame 5. The support frame 5 supports the slide seat 6 to move up and down. A slide groove 14 is provided on the inner side of the support frame 5, and the inner wall of the slide groove 14 is slidably connected to the outer surface of the slide seat 6. The slide seat 6 can increase the stability when moving up and down through the slide groove 14, and guide the sliding direction of the slide seat 6.

[0025] A first motor 7 is installed on the upper surface of the slide 6. The first motor 7 is used as a power source to drive the rotating rod 8 to rotate. When the rotating rod 8 rotates, the brush 9 is also driven to rotate. The output shaft of the first motor 7 is connected to the rotating rod 8. The rotating rod 8 passes through one end of the slide 6 and is connected to the brush 9. The outer surface of the brush 9 is slidably connected to the inner bottom wall of the screen frame 4. The upper surface of the slide 6 is connected to a frame 15, and the frame 15 is located outside the first motor 7. The inner side of the support frame 5 is threadedly connected to a screw rod 16. One end of the screw rod 16 is rotatably connected to the upper surface of the frame 15 at a fixed point, and the other end of the screw rod 16 is connected to a rotating wheel 17. By rotating the screw rod 16, the slide 6 is driven to move up and down, and the brush 9 is driven to move up and down at the same time. The contact force between the brush 9 and the screen frame 4 can be adjusted, and the space can be expanded when the screen frame 4 is superimposed on the screen frame 4.

[0026] A second motor 12 is installed at the bottom end of the bottom frame 3. The output shaft of the second motor 12 is connected to an eccentric wheel 13. The eccentric wheel 13 is driven to rotate by the rotation of the first motor 7. When the eccentric wheel 13 rotates, its center of gravity is not at the center of rotation, so that the centrifugal force generated by the eccentric wheel 13 during rotation will cause the eccentric wheel 13 to deviate to one side to form vibration, thereby providing vibration power for the vibrating screen.

[0027] A support rod 18 is connected to one side of the slide 6, one end of the support rod 18 is connected to a feed pipe 19, one end of the feed pipe 19 is located inside the screen frame 4, and the other end of the support rod 18 is connected to a hopper 20. The feed pipe 19 has an inclined angle to facilitate the magnesium powder to slide into the screen frame 4. When screening the magnesium powder, it is convenient to add the magnesium powder into the vibrating screen through the transmission of the hopper 20 and the feed pipe 19.

[0028] The outer surface of the sieve frame 4 is connected to a first discharge pipe 21, and the first discharge pipe 21 is connected to the inside of the sieve frame 4. The outer surface of the bottom frame 3 is connected to a second discharge pipe 22, and the second discharge pipe 22 is connected to the inside of the bottom frame 3. The large-particle magnesium powder that cannot be screened and filtered in the sieve frame 4 is discharged through the first discharge pipe 21, and the magnesium powder that has been screened and filtered in the bottom frame 3 is discharged through the second discharge pipe 22.

[0029] It should be noted that in actual use of the device, magnesium powder is first poured into the hopper 20, and at the same time, the first motor 7 is started to rotate to drive the rotating rod 8 to rotate. After the rotating rod 8 rotates, it drives the brush 9 to rotate. The magnesium powder after entering the hopper 20 slides into the center position of the screen frame 4 through the feed pipe 19. The magnesium powder jumps to the outside under the vibration of the vibrating screen. Magnesium powder particles smaller than the diameter of the holes on the screen frame 4 will pass through the holes and fall into the bottom frame 3. Magnesium powder particles larger than the diameter of the holes cannot fall or get stuck in the holes. Then, when the brush 9 rotates, the seam-beautifying particles stuck in the holes are swept out and jump to the outside under the vibration of the vibrating screen.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
