Description

Technical Field

[0001] The utility model relates to the field of mineral processing, in particular to a mining vibrating screen with a cleaning function. Background Art

[0002] Mining vibrating screen adopts advanced technologies at home and abroad such as vibration motor excitation, rubber spring vibration reduction, high wear-resistant material screen plate, sealed screen box and advanced self-synchronous vibration principle. It has the characteristics of long life, low noise and high screening efficiency. It is a vibrating screening equipment suitable for sintered ore, natural ore, coke and other powdered materials.

[0003] The patent with authorized 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 patented design uses the exhaust fan to suck the dust from the vibration trough into the dust collecting box, thereby reducing dust. It can successfully suppress dust escape during screening operations and ensure the cleanliness of the working environment. However, it ignores the key link of screen plate maintenance, that is, the lack of an automatic cleaning mechanism. As the screening work continues, small ores or impurities will inevitably be retained between the screen plates. These residues accumulate over time and gradually erode the permeability of the screen plates, which will inevitably lower the overall screening quality and affect the purity and accuracy of the screened products. Therefore, how to design a mining vibrating screen with a cleaning function has become a problem to be solved at present. Utility Model Content

[0019] First of all, it should be noted that in the various embodiments described, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0020] Example: A mining vibrating screen with cleaning function, such as Figure 1 and Figure 2The screen plate 4 is slidably mounted on the frame 1 through the sliding frame 3, and the steel brush 5 is slidably mounted on the screen plate 4 through the sliding frame 3. The bristles on the steel brush 5 are attached to the screening plate surface of the screen plate 4. Sliding the steel brush 5 can clean the ore fragments blocked on the sieve holes of the screen plate 4, wherein the slider 6 is slidably clamped on the top side wall of the screen plate 4, and the swing assembly is arranged on the right side of the mounting plate 2. The swing assembly is used to drive the screen plate 4 to vibrate back and forth, so that the screen plate 4 can automatically vibrate and screen the ore fragments.

[0021] like Figure 3 As shown, the swing assembly includes: a motor 7, a crank 8, a fixed rod 9, a connecting rod 10 and a link shaft 11. The motor 7 is fixedly mounted on the lower side of the right plate surface of the mounting plate 2, and the output shaft of the motor 7 passes upward through the plate surface of the mounting plate 2. The crank 8 is fixedly mounted on the end of the output shaft of the motor 7, and the fixed rod 9 is fixedly mounted on the lower side of the screen plate 4. The connecting rod 10 is rotatably connected to the end of the fixed rod 9, and the link shaft 11 is hinged to the ends of the crank 8 and the connecting rod 10. The motor 7 drives the crank 8 to rotate, thereby driving the connecting rod 10 and the link shaft 11 to cooperate in reciprocating motion, so that the screen plate 4 can reciprocate.

[0022] like Figure 3 As shown, the sieve plate 4 is set as a whole to be slightly tilted downward from right to left, and the right side frame of the sieve plate 4 is an inclined blanking plate; initially, the steel brush 5 is located below the bottom of the blanking plate on the sieve plate 4, and the steel brush 5 can be removed and replaced on the slider 6. When the steel brush 5 is worn out after long-term use, it can be removed from the sliders 6 on both sides for replacement, so that the steel brush 5 can effectively clean the sieve plate 4.

[0023] like Figure 3 and Figure 4As shown, it also includes a connecting frame 12, a water inlet frame 13, a nozzle 14 and a water receiving pipe 15. The connecting frame 12 is fixedly installed between the sliders 6 on both sides, and the connecting frame 12 is respectively located at the lower part of the front and rear sides of the mounting plate 2. The water inlet frame 13 is installed between the two connecting frames 12. A plurality of nozzles 14 are provided and installed on the top of the water inlet frame 13. The nozzle 14 is located directly below the sieve plate 4. The water receiving pipe 15 is connected to the front and rear sides of the water inlet frame 13. The water receiving pipe 15 is externally connected to a high-pressure water pump to supply water to the water inlet frame 13; the water inlet frame 13 is detachably installed on the connecting frame 12. Replacing the water inlet frame 13 of different specifications can synchronously change the number of the nozzles 14 thereon, thereby meeting the cleaning requirements of different screening situations.

[0024] When it is necessary to screen the processed ore, this vibrating screen can be used. The user can pour the ore fragments that need to be screened from the discharge plate on the right side of the screen plate 4. After pouring the ore to be screened, the motor 7 is activated. The motor 7 drives the crank 8 to rotate through the output shaft. After the crank 8 rotates, it will repeatedly drive the connecting rod 10 to move. At this time, the crank 8 and the connecting rod 10 will rotate reciprocatingly with the fixed rod 9 as the axis point. The reciprocating connecting rod 10 will drive the screen plate 4 to move through the fixed rod 9. The driven screen plate 4 will follow the connecting rod 10 and the crank 8 to reciprocate left and right synchronously under the guidance of the sliding frame 3, thereby realizing the reciprocating vibration of the screen plate 4 on the frame 1. At this time, the ore fragments will slide evenly from the discharge plate into the screen plate 4, and when being continuously screened by the screen plate 4, the ore fragments will tilt with the screen plate 4. It rolls slowly from right to left so that the ore debris can be evenly spread and screened on the sieve plate 4. After completing a round of ore debris screening, the user turns off the motor 7 and then pushes the slider 6 manually or with a tool. After the slider 6 is pushed, it drives the steel brush 5 to move synchronously. At this time, the steel brush 5 will move in contact with the sieve plate 4, so that the steel brush 5 can clean the sieve holes on the sieve plate 4 to prevent large pieces of ore from being blocked in the sieve holes. At the same time, water can be injected into the water pipe 15 through an external water pump. The injected water will flow into the water inlet frame 13, and after gradually filling the entire water inlet frame 13, it will be sprayed upward from multiple nozzles 14. The sprayed water will flush the sieve plate 4, thereby cooperating with the steel brush 5 to brush synchronously, so that the nozzle 14 can synchronously follow the steel brush 5 to clean the entire sieve plate 4, thereby achieving efficient cleaning of the vibrating screen.
