Technical Field

[0001] The utility model belongs to the field of processing mineral products, and specifically relates to a screening device for mineral products. Background Art

[0002] With the continuous development of the mining industry, after the ore is mined, it will be divided into different grades according to different parameters such as particle size and composition. Particle size is an important criterion for measuring ore; particles that are too large or too small will affect the price of the ore, and materials such as slag and ore are frequently used building materials in the construction process, but ordinary stone is generally large in size and does not meet the requirements of building stone. However, when minerals are processed, granular materials of different particle sizes need to be screened. When screening existing minerals, there is a problem of different sizes of screened particles, and improper post-screening processing reduces work efficiency and increases production costs.

[0003] The patent application with publication number CN209549936U discloses a screening device for mineral products, including: a base plate, four supporting columns are fixedly connected to the middle of the top of the base plate, the ends of the four supporting columns away from the base plate are fixedly connected to a screening box, a feed pipe is provided on one side of the top of the screening box, a feed port is provided on the top of the feed pipe, a first screening net, a second screening net and an inner slide are provided inside the screening box, and a vibrator is fixedly connected to the middle of the bottom of the screening box.

[0004] The above patent simply sets up a vibrating machine to vibrate multiple screening nets in the screening box to assist in screening mineral products. However, after the screening is completed, manual unloading is required, which makes unloading more difficult, reduces work efficiency, and is more dangerous, increasing the risk for workers at work.

A lifting assembly 9 corresponding to one end of the bottom of the barrel body 2 is provided on the other side of the base 1. The sieve hole diameters of the first screening net 3, the second screening net 4 and the third screening net 5 decrease from top to bottom, and a feed port 14 is provided on the top of the barrel body 2.

[0033] One aspect of the application of this embodiment is: when the device is needed to screen mineral products, the mineral products to be screened are first added into the barrel body 2 from the feed port 14 at the top of the barrel body 2, and the mineral products will fall above the first screening net 3. Then, the stirring component 12 is started, and the stirring component 12 will push the mineral products to move above the first screening net 3. At this time, the smaller mineral products fall from the first screening net 3 to the second screening net 4, and the larger mineral products stay above the first screening net 3. Then the stirring component 12 continues to stir the second screening net 3. 4 is stirred and screened, so that the mineral products fall to the top of the third screening net 5 and the bottom of the barrel 2 in turn, thereby completing the screening of the mineral products. After the classification of the mineral products is completed, the stirring component 12 is turned off, and then the lifting component 9 is started. The lifting component 9 tilts the barrel 2 so that the multiple discharge door components 6 of the barrel 2 correspond to the discharge tray 7, and then the multiple discharge door components 6 are opened. The mineral products that have completed the screening will slide into the discharge tray 7 through the multiple discharge door components 6, thereby completing the screening and discharging of the mineral products. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supplies.

The lifting assembly 9 includes a hydraulic cylinder 901 fixed to the middle of the groove 8, and a hydraulic rod 902 fixed to the output end of the hydraulic cylinder 901. One end of the hydraulic rod 902 is rotatably matched with one end of the bottom of the barrel body 2.

[0035] When it is necessary to discharge the classified mineral products through the lifting component 9, the hydraulic cylinder 901 is started, and the output end of the hydraulic cylinder 901 pushes the hydraulic rod 902 to rise. One end of the hydraulic rod 902 rotates and cooperates with one end of the bottom of the barrel body 2, and at the same time drives one end of the bottom of the barrel body 2 to rise. At this time, the other end of the bottom of the barrel body 2 rotates around the rotating shaft 11, so that the barrel body 2 can be tilted, and the mineral products that have been screened will slide into the discharge tray 7 through multiple discharge door components 6 respectively, completing the mineral product screening and discharge.

[0037] When it is necessary to accelerate the falling of the mineral products through the stirring assembly 12, the motor 121 is started, and the output end of the motor 121 drives the stirring rod 122 to rotate. The stirring rod 122 drives the three stirring plates 123 fixed on the side of the stirring rod 122 to rotate on the upper side of the first screening net 3, the second screening net 4, and the third screening net 5, so as to stir the mineral products on the upper side of the first screening net 3, the second screening net 4, and the third screening net 5, thereby accelerating the falling of the mineral products.

The discharge tray 7 is divided into four discharge areas 702 by the three baffles 701, and the four discharge areas 702 correspond to the four discharge ports 601 respectively.

[0039] When the classified mineral products need to be discharged through the discharge door assembly 6, the lifting assembly 9 is started, and the lifting assembly 9 tilts the barrel body 2. When the four discharge ports 601 are respectively opposite to the four discharge areas 702, the lifting assembly 9 is shut down, and then all four discharge doors 602 are opened. Subsequently, the classified mineral products will slide through the four discharge ports 601 into the four discharge areas 702 respectively, completing the discharge of the mineral products.
