[0002] Ore screening device is a mechanical equipment used for ore processing. Its main function is to classify and screen raw ore according to its physical properties (such as size, shape, density, etc.).

[0003] The automatic feeding ore screening device usually includes an automatic feeder, which can evenly and continuously transport the ore to the feed port of the screening machine, thereby realizing automatic feeding of the ore. It can automatically feed the original ore into the screening device for grading.

[0004] At present, the existing automatic feeding ore screening device cannot effectively absorb the impurities and dust raised in the box during the screening process, causing dust to pollute the environment and affect the working environment. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the impurities and dust raised in the box during the screening process cannot be effectively sucked out, resulting in dust pollution to the environment and affecting the working environment, and to propose an automatic feeding ore screening device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An automatic feeding ore screening device, comprising:

[0008] The base has a rectangular top with four springs fixedly provided thereon, a box body is fixedly provided on the top of the four springs, a cover plate is hingedly connected to the top of the box body by a hinge, and a hoist is detachably provided on the top of the base body next to the box body;

[0009] The dust suction component is arranged on the cover plate and is used to suck away impurities and dust raised during the ore screening process.

[0010] In one possible design, the dust collection assembly includes a dust collection box fixedly arranged on the top of the cover plate, and connecting pipes are fixedly connected on both sides of the dust collection box. One end of the two connecting pipes passes through the cover plate and is connected to the box body. The top of the dust collection box is symmetrical and can be detachably sealed and plugged with two plug-in racks. Filter elements are removably arranged inside the two plug-in racks, and a fan is fixedly connected to one side of the dust collection box.

[0011] In one possible design, a sieve plate one is detachably provided inside the box body, a sieve plate two is detachably provided inside the box body below the sieve plate one, a sieve plate three is detachably provided inside the box body below the sieve plate two, a slag discharge trough is provided inside the box body below the sieve plate three, and a vibrator is fixedly provided at the bottom of the box body.

[0012] In one possible design, a discharge pipe one is fixedly provided at the first sieve plate on one side of the box body, a discharge pipe two is fixedly provided at the second sieve plate on one side of the box body, a discharge pipe three is fixedly provided at the third sieve plate on one side of the box body, and a slag discharge pipe is fixedly provided at the bottom of the box body, and the slag discharge pipe is connected to the slag discharge trough.

[0013] In a possible design, the top of the cover plate is fixedly connected to a feed port, and the discharge port of the elevator is located directly above the feed port of the cover plate.

[0014] In a possible design, the bottom of the base is rectangular and fixed with four universal brake wheels.

[0015] In a possible design, the cover plate is fixed to the box body by means of a buckle lock.

[0016] In this application, when starting to use, first move the device to the working area through the universal brake wheel, then use the universal brake wheel to adjust and fix the position, then check whether the sieve plates 1, 2 and 3 in the box are firmly installed, and adjust or replace the sieve plates as needed, and then connect the device to the power supply.

[0017] Start the hoist, vibrator and fan to put the equipment in normal working condition.

[0018] The hoist lifts the ore to the top of the feed port, and then it falls into the feed port through the discharge port of the hoist and enters the box for screening. After the ore enters the box, it first falls on the sieve plate 1 for the initial screening. According to the aperture size of the sieve plate, the ore is divided into different particle size levels. The larger particle size ore screened out by the sieve plate 1, the remaining ore falls on the sieve plate 2 through the holes of the sieve plate 1 for the second screening, the medium particle size ore screened out by the sieve plate 2, the remaining ore falls on the sieve plate 3 through the holes of the sieve plate 2 for the third screening, the small and medium particle size ore screened out by the sieve plate 3, the remaining crushed stone or Impurities fall into the slag discharge trough below through the holes of screen plate three to collect fine slag that cannot pass through the screening. During the screening process, the vibrator at the bottom of the box continues to work to help the ore pass through the screen plate smoothly, thereby improving the screening efficiency. The larger particle size ore screened by screen plate one is discharged through discharge pipe one and collected in the corresponding container. The medium particle size ore screened by screen plate two is discharged through discharge pipe two and collected in the corresponding container. The smaller particle size ore screened by screen plate three is discharged through discharge pipe three and collected in the corresponding container. The fine slag enters the slag discharge pipe through the slag discharge trough and is finally discharged out of the device.

[0019] During the entire screening process, the dust collection component continues to work, and the fan sucks the inside of the dust collection box, creating a negative pressure inside the dust collection box to suck the connecting pipe, and then the dust and impurities inside the box are sucked into the dust collection box through the connecting pipe. The filter element will absorb the impurities and dust and then discharge the clean air to prevent dust from entering the fan, while impurities and dust are left in the dust collection box. During the screening process, the vibration frequency of the vibrator and the suction force of the fan can be adjusted as needed to obtain the best screening effect.

[0020] The utility model has the following beneficial effects:

[0021] The utility model is provided with a dust collection component, and the fan sucks the inside of the dust collection box, so that a negative pressure is formed inside the dust collection box to suck the inside of the connecting pipe, and then the dust and impurities inside the box are sucked into the dust collection box through the connecting pipe, which can effectively remove the dust generated in the ore screening process, thereby greatly reducing the pollution of dust to the environment and creating a safer and healthier working environment for workers.

[0022] In the utility model, through the arrangement of the sieve plate 1, the sieve plate 2, the sieve plate 3, the slag discharge trough, the discharge pipe 1, the discharge pipe 2, the discharge pipe 3 and the slag discharge pipe, accurate classification screening can be performed according to the particle size of the ore. The sieve plates with different sieve holes can separate the ore according to different particle sizes to meet different use requirements, improve the utilization value of the ore, and discharge the ores of different particle sizes separately to facilitate subsequent processing and utilization, thereby improving the overall efficiency of ore screening.

[0023] The utility model can effectively absorb the dust generated in the ore screening process by setting the dust suction component, thereby greatly reducing the pollution of dust to the environment and creating a safer and healthier working environment for workers.

Two plug-in racks 8 are symmetrically provided on the top of the dust collection box 6. A filter element 9 is detachably installed in the plug-in rack 8 for filtering the inhaled air and preventing dust from entering the fan 10. At the same time, it is convenient to remove and replace the filter element 9. A fan 10 (model: CX-100) is fixedly connected to one side of the dust collection box 6 for providing dust collection power. The fan 10 sucks the interior of the dust collection box 3, so that a negative pressure is formed inside the dust collection box 3 to suck the connecting pipe 7, and then the dust and impurities inside the box body 3 are sucked into the dust collection box 6 through the connecting pipe 7, which can effectively remove the dust generated during the ore screening process, thereby greatly reducing the pollution of dust to the environment and creating a safer and healthier working environment for workers.

[0035] Inside the box 3, sieve plate 1 16, sieve plate 2 17 and sieve plate 3 18 are detachably arranged from top to bottom. The aperture of sieve plate 1 16 is larger than that of sieve plate 2 17, and the aperture of sieve plate 2 17 is larger than that of sieve plate 3 18, and they are used to screen out ores of different particle sizes. A discharge pipe 1 11, a discharge pipe 2 12 and a discharge pipe 3 13 connected to sieve plate 1 16, sieve plate 2 17 and sieve plate 3 18 are respectively provided on one side of the box 3, and are used to discharge ores of different particle sizes screened out. For ore discharge, a slag discharge trough 19 is provided inside the box body 3 below the sieve plate 3 18 for collecting fine slag that cannot pass through the screening. The slag discharge trough 19 is connected to the slag discharge pipe 14 at the bottom of the box body 3 to facilitate the discharge of fine slag. In order to further improve the screening effect, a vibrator 301 (model: ZFB / LZF-3) is fixedly provided at the bottom of the box body 3 to generate vibration during the screening process to help the ore pass through the sieve plate.

[0036] The present application can be used in the technical field of automatic loading ore screening devices, and can also be used in other fields applicable to the present application.
