Description

Technical Field

[0001] The utility model relates to a vibrating screen, in particular to a compressed air ore washing vibrating screen for mining. Background Art

[0002] The vibrating screen works by utilizing the reciprocating vibration generated by the vibrator excitation. The upper rotating hammer of the vibrator causes the screen surface to produce planar gyratory vibration, while the lower rotating hammer causes the screen surface to produce conical gyratory vibration. The combined effect causes the screen surface to produce compound gyratory vibration. The compressed air washing vibrating screen combines compressed air washing technology and vibration screening technology. It is mainly used to improve the cleanliness and screening efficiency of minerals. This type of vibrating screen is very critical in the mineral processing process, especially when processing ores containing a large amount of impurities or clay.

[0003] Patent announcement number CN214638097U discloses a vibrating screen for ore washing, including a base, the bottom of the base is provided with a shock-absorbing pad, and support rods are connected to both sides of the upper part of the base, the support rods are fixedly connected to the base, and the end of the support rod away from the base is fixedly connected to a vibration trough, a vibration motor is installed at the left end of the vibration trough, a coarse ore outlet is provided at the right end of the vibration trough, and a fine ore outlet is provided at the bottom of the vibration trough, a dust box is provided on the left side of the base, and a dust hood is provided on the top of the vibration trough.

[0004] The above patent is provided with a dust box and a dust hood, and the dust at the vibration trough is sucked into the dust box by the action of the exhaust fan, thereby reducing the dust. However, when faced with highly sticky materials, the sticky particles move slowly on the screen due to their own characteristics, and are easy to stick to each other and gradually accumulate, eventually causing the screen aperture to be blocked. This phenomenon not only greatly reduces the screening efficiency, but also may make the vibrating screen completely unable to perform its due separation function. Therefore, it is necessary to design a compressed air ore washing vibrating screen for mining to solve the above problems. Utility Model Content

[0005] In order to overcome the disadvantage of the existing mining vibrating screen that when screening minerals with sticky particles, the sticky particles are easily blocked by the vibrating screen after being screened out, a compressed air ore washing vibrating screen for mining is provided.

[0006] The technical implementation scheme of the utility model is: a compressed air ore washing vibrating screen for mining, comprising a frame, an outer shell, a lower hopper, a sieve plate, an exciter, a connecting plate, a motor, a gear, a clamping tooth and an air washing assembly, the frame being a mounting carrier for the vibrating screen, the outer shell being fixedly mounted on the frame, the lower hopper being arranged on the right part of the top side of the outer shell, the sieve plate being rotatably mounted on the lower part of the inner wall of the outer shell, the vibrator being symmetrically mounted on the upper part of the inner wall of the sieve plate, the connecting plate being fixedly mounted on the right end part of the sieve plate, the connecting plate being slidably connected to the outer shell, the motor being mounted on the right side of the frame, the gear being mounted on the output shaft of the motor, the clamping tooth being provided with a plurality of teeth and being circumferentially arranged on the lower part of the side wall of the connecting plate, the gear and the clamping tooth being meshed with each other, the air washing assembly being mounted on the outer wall of the outer shell, and the air washing assembly being capable of inflating air into the outer shell and performing air washing of the ore.

[0008] Furthermore, the outer shell and the sieve plate are both designed to be inclined on the frame, and the outer shell is inclined downward from the connecting plate toward the baffle.

[0009] Furthermore, it also includes a baffle and an arc plate. The baffle is detachably installed at the left opening of the shell. The baffle can rotate relative to the shell. The arc plate is arranged at the lower part of the inner wall of the baffle.

The air washing assembly can inflate the inner shell 2 and perform air washing.

[0020] like Figure 2As shown, the air washing assembly includes an air intake frame 13, an air nozzle 12 and an air intake pipe 14. The air intake frame 13 is fixedly mounted on the outer wall of the outer shell 2. A plurality of air nozzles 12 are provided and mounted on the air intake frame 13. The air nozzles 12 all pass through between the outer shell 2 and the sieve plate 4. The air jets of the air nozzles 12 face the outer wall of the sieve plate 4. The air intake pipe 14 is connected to one side of the air intake frame 13. The air intake pipe 14 can be externally connected to an air pump. The air nozzle 12 can blow gas into the outer shell 2 and air-wash the minerals. The outer shell 2 and the sieve plate 4 are both inclined on the frame 1, and the outer shell 2 is inclined downward from the connecting plate 6 toward the baffle 10.

[0021] like Figure 3 As shown, it also includes a baffle 10 and a curved plate 11. The baffle 10 is detachably mounted on the left opening of the outer shell 2, and the baffle 10 can rotate relative to the outer shell 2. The curved plate 11 is arranged at the lower part of the inner wall of the baffle 10. The baffle 10 cooperates with the sieve plate 4 through the curved plate 11, so that the baffle 10 can be installed on the sieve plate 4 and prevent mineral particles from being blown out during air washing; sealing gaskets are provided on the surface sides of the baffle 10 and the curved plate 11, the baffle 10 can be sealed and mounted on the outer shell 2, and the curved plate 11 can be sealed and fitted on the sieve plate 4; it also includes a partition 15, the partition 15 is evenly arranged on the inner wall of the sieve plate 4, the partition 15 divides the lower part of the inner wall of the sieve plate 4 into a plurality of uniform compartments, which can evenly disperse the minerals screened by the vibrating screen, thereby improving the efficiency and accuracy of screening.

[0022] When air washing and screening is required, this vibrating screen can be used. First, push the baffle 10 into the left opening of the shell 2 for installation. After installation, the arc plate 11 on the single shift will seal the gap between the screen plate 4 and the shell 2. Then start the motor 7. The motor 7 drives the gear 8 to rotate intermittently through the output shaft. The reciprocating gear 8 will drive the connecting plate 6 to rotate after engaging multiple teeth 9. At this time, the connecting plate 6 will drive the screen plate 4 and the baffle 10 to reciprocate synchronously.

When the air intake frame 13 is full of gas, it will be sprayed from multiple air nozzles 12 onto the outer wall of the sieve plate 4, so as to blow down the minerals that may be sticky or stuck, and avoid the minerals from being blocked in the sieve holes in the sieve plate 4. The blown-down minerals will continue to be screened by the sieve plate 4, thereby realizing the mineral gas washing work. After gas washing and screening, the minerals will eventually slide to a position close to the baffle 10, and finally the screened minerals can be conveniently collected by turning to open the baffle 10.
