[0002] Chinese patent document CN214052542U discloses a novel stacked vibrating coal screening machine, including a mounting plate, a water tank, a machine body, and a linear motor. Multiple shock-absorbing buffer devices are vertically arranged at the bottom of the mounting plate, and connecting columns are provided on both sides of the top wall of the mounting plate. The water tank is located on the left side of the top of the mounting plate. Inside the machine body, a first screen, a second screen, and a third screen are arranged obliquely from top to bottom, which can further improve the accuracy of screening coal particle size. Three cleaning rollers are respectively attached to the bottom surfaces of the three screens, cleaning them to remove slag adhering to the screens and prevent clogging. A water pipe connected to the internal cavity of the machine body pressurizes the water in the tank via a booster pump and flushes it onto the screens to prevent clogging, thereby improving screening efficiency and accuracy. Shock-absorbing buffer devices are also provided at the bottom of the machine body.

[0003] During the mining and processing of ore, screening is also required to remove debris and impurities. However, for the aforementioned machines, the collision of materials inside the machine and the collision of materials falling and being collected will spread surface dust into the air, causing pollution. The dust escaping from the machine can also be harmful to the human body. Therefore, we propose a stacked ore vibrating screening conveyor belt. Utility Model Content

[0004] The purpose of this invention is to provide a stacked ore vibrating screening conveyor belt, which can solve the problem of pollution caused by dust spreading due to collisions in some existing screening machines.

Two sets of collection boxes 7 are placed on the top of the base plate 1. Both sets of collection boxes 7 are attached to the bottom of the screening box 2. Two sets of limiting frames 8 are fixedly installed on the top of the base plate 1. Both sets of collection boxes 7 are attached to the inner wall of the corresponding limiting frame 8. A hopper 9 is fixedly installed on the top of the screening box 2.

[0025] The dust collection mechanism 4 is located on one side of the screening box 2. The dust collection mechanism 4 includes a blower 41 and a dust collection pipe 42. The blower 41 is fixedly installed on the outer surface of one side of the screening box 2. The dust collection pipe 42 is fixedly installed on the top of the blower 41. One end of the dust collection pipe 42 is connected to the input end of the blower 41, and the other end of the dust collection pipe 42 passes through one side of the screening box 2 and extends into the interior of the screening box 2.

[0026] The dust collection mechanism 4 also includes a filter cylinder 43, a filter screen 44, and a magnetic sheet 45. The filter cylinder 43 is fixedly installed at the bottom of the blower 41. The output end of the blower 41 is connected to the inside of the filter cylinder 43. Two sets of slots are opened on the front side of the filter cylinder 43, and a set of filter screens 44 are installed in each set of slots. A magnetic sheet 45 is magnetically attracted to the outer surface of the front side of the filter cylinder 43. Through the dust collection mechanism 4, during the ore screening process, the dust that spreads from the ore poured into the screening box 2 and the dust generated when the ore falls into the collection box 7 can be absorbed and filtered and collected in the screening box 2. The screening box 2 and the collection box 7 are set in close contact, and the dust will not escape from the screening box 2. This solves the problem that in some existing machines, the collision of materials inside the machine and the collision of materials falling and collecting will spread surface dust into the air and cause pollution. The dust that escapes from the machine will also cause harm to the human body. This improves the practicality of the conveyor belt.

[0027] The screening mechanism 5 includes a rectangular frame 51, a transmission roller 52, a perforated conveyor belt 53, a non-perforated conveyor belt 54, and a servo motor 55. Two sets of rectangular frames 51 are fixedly installed between the front and rear inner walls of the screening box 2. Two sets of transmission rollers 52 are rotatably installed between the front and rear inner walls of the two sets of rectangular frames 51. A perforated conveyor belt 53 and a non-perforated conveyor belt 54 are sleeved between each pair of transmission rollers 52.

The rotating shafts of the two sets of servo motors 55 are connected to the corresponding transmission rollers 52. Through the screening mechanism 5, the stacked arrangement can realize the synchronous screening of ore during continuous conveying. At the same time, under the action of the vibrating plate 6, it can help the slag and impurities in the ore pass through the perforated conveyor belt 53 to speed up the screening, ensuring the use effect of the conveyor belt and facilitating the promotion and use of the conveyor belt.

[0028] Working principle: The system controls two sets of servo motors 55 to start and drive the perforated conveyor belt 53 and the non-perforated conveyor belt 54. The system controls the start of the induced draft fan 41 and the start of the vibrating plate 6 to vibrate the perforated conveyor belt 53. The ore is poured into the screening box 2 and slowly transported on the perforated conveyor belt 53. The vibration causes the debris and impurities to fall onto the non-perforated conveyor belt 54 for further transport. The ore on the perforated conveyor belt 53 eventually falls onto one set of collection boxes 7. The non-perforated conveyor belt 54 transports the debris and impurities to another set of collection boxes 7. The induced draft fan 41 sucks the dust in the screening box 2 into the filter cylinder 43 through the dust suction pipe 42 and filters it through the filter screen 44 before discharging it. During operation, when the upper filter screen 44 needs cleaning, it is pulled out and the magnetic piece 45 covers the corresponding slot. The dust is then filtered through the lower filter screen 44 and the pulled-out filter screen 44 is cleaned, thus avoiding the dust suction mechanism 4 from stopping.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
