Description

technical field [0001] The invention relates to the field of sorting machines, in particular to a multi-mass specific gravity sorting machine. Background technique [0002] Separators are widely used in the classification and screening of broken materials. According to the difference in structure and movement of sieve plates, separators can usually be divided into vibratory separators, drum separators, relaxation separators, and bar separators. Sorting machine, vibrating wind compound sorting machine and other forms. When the sorter is working, the material enters the sieve plate at a certain speed and inclination, and through the different forms of movement of the sieve plate, the material is gradually dispersed, segregated, and separated through the sieve. The incident speed, angle and position of the material will affect the sorting effect and efficiency of the sorting machine. The structure of the existing vibratory wind compound separator is from top to bottom in orde...

Problems solved by technology

[0003] ① Low sorting efficiency:

[0004] The existing feeding device is generally made according to the size of the material conveying belt, and its width is quite different from that of the sieve plate of the sorting machine, which makes it difficult for the material to spread evenly on the sieve plate, especially at the front end of the sieve plate The materials on both sides are often difficult to reach; after the feed box is installed and fixed, its material incidence angle is relatively fixed, so the material falling position is relatively concentrated, thereby reducing the effective use area of ​​the sieve plate and the separation efficiency; at the same time, when the material When there are many types and complex material components, maintain a fixed material incident angle, and the multi-type and multi-component materials fall on the relatively concentrated position on the sieve plate, so it is difficult to achieve the expected sorting effect; because the falling material position is relatively concentrated, this It also reduces the effective utilization area of ​​the sieve plate, and the materials falling onto the sieve plate through the feed box are concentrated near the feeding point, and it is difficult to reach the parts on both sides of the front end of the sieve plate, and the distribution of materials on the sieve plate is uneven On the one hand, it wastes the production capacity of the equipment, and on the other hand, it also reduces the sorting efficiency; the air inlet of the vibratory wind compound separator is located under the sieve plate, and the air inlet or outlet is located on the end side of the feeding device, which makes The wind field in the feed box is chaotic, even forming backflow wind and whirling wind, so that the light materials that need to be sorted by wind cannot be effectively discharged from the air inlet or outlet, which leads to low sorting efficiency; It enters the inside of the air inlet box through the straight-through air inlet pipe and blows upwards to the sieve plate, and there is no corresponding flow diversion and guiding device inside the screen box, which makes the external air supply from the air inlet box arrive at the sieve plate. The air flow is too concentrated and cannot be effectively and evenly distributed to all parts of the sieve plate, resulting in local material accumulation on the sieve plate, which reduces the separation efficiency; at the same time, because the external air supply enters the screen box through the air inlet box and reaches the sieve plate, the existence of the air inlet box As a result, part of the wind loss occurs when the external air comes into contact with the sieve plate, and the sorting efficiency of the materials that need to be sorted by wind is also reduced after the wind pressure is reduced;

[0005] ②Fine particles are not easy to collect: because the fine particles fall to the bottom of the air inlet box and are discharged from the bottom of the air inlet box after passing through the soft connection, the external air supply from the air inlet box will hinder the falling of the fine particles, or even The fine particles are blown to the inner wall of the air inlet box, which makes it difficult for the fine particles to be collected; at the same time, because the box body of the air inlet box is relatively high, this also prolongs the action time of the external air supply on the fine particles and delays The falling time of fine particles increases the difficulty of collecting fine particles;

[0006] ③Reduce the service life of the sieve plate: due to the uneven distribution of materials on the sieve plate and the relative concentration of the blanking position, it is easy to cause concentrated impact and wear on the local area of ​​the sieve plate of the sorter, which significantly reduces the life of the sieve plate. short;

[0007] ④ Reduce the overall stability of the sorting machine: The existence of the air inlet box increases the overall height of the sorting machine and raises the center of gravity of the sorting machine, which leads to a decrease in the overall stability of the sorting machine;

[0008] ⑤Increased installation and maintenance costs and civil engineering costs: Since there is no air-lock discharge mechanism inside the screen box, in order to ensure the air pressure inside the screen box and discharge fine particles, it is necessary to install a two-way screw conveyor and a star-shaped ash discharge valve at the bottom of the air inlet box , which leads to an increase in the manufacturing and maintenance costs of the sorting machine, and also increases the overall height of the sorting machine, which increases the civil construction cost of the factory building, etc.
