Description

Multi-mass specific weight sorting machine

Technical Field

The invention relates to the field of sorting machines, in particular to a multi-mass specific gravity sorting machine.

Background

The sorting machine is widely used for grading and screening scattered materials, and can be generally divided into various forms such as a vibration sorting machine, a roller sorting machine, a relaxation sorting machine, a bar sorting machine, a vibration wind power composite sorting machine and the like according to the difference of the structure and the motion form of a sieve plate. When the separator works, materials fall into the sieve plate at a certain speed and an inclination angle, and are gradually dispersed, separated and sieved and separated through the movement of different forms of the sieve plate. The incident speed, angle and position of the material all affect the sorting effect and sorting efficiency of the sorting machine. The structure of the existing vibration wind power composite sorting machine is that a feeding box, a sieve plate, a sieve box, an air inlet box and a vibration driving module are sequentially arranged from top to bottom, the feeding box is connected with the sieve box, the sieve plate is arranged in the sieve box, the sieve box is connected with the air inlet box, the vibration driving module is connected with the sieve box and positioned on two sides of the air inlet box, the front end and the rear end of the sieve box are provided with a heavy particle material outlet and a light particle material outlet, the fine particle materials fall to the bottom of the air inlet box after passing through the sieve plate and are discharged through a single-shaft bidirectional screw conveyor and a star-shaped ash discharge valve, and the light material is discharged from an air induction port on one side of the end part of the feeding box under the action of wind power. The invention discloses a vibration and wind power composite sorting device based on density difference and a using method thereof, and a dry type sorting system and a sorting method of construction waste, as disclosed in Chinese patent application CN109107895A and CN 110694910A. However, the following main problems exist in the prior art:

sorting efficiency is low:

the existing feeding device is generally manufactured according to the size of a material conveying belt, the difference between the width of the existing feeding device and the width of a sieve plate of a sorting machine is large, so that materials are difficult to uniformly disperse and tile on the sieve plate, and particularly, the materials are difficult to reach at the parts close to two sides of the front end of the sieve plate; after the feeding box is installed and fixed, the incident angle of the materials is relatively fixed, so that the blanking positions of the materials are relatively concentrated, and the effective utilization area and the sorting efficiency of the sieve plate are reduced; meanwhile, when the types of materials are various and the components of the materials are complex, the fixed incident angle of the materials is maintained, and the materials of various types and components fall on the relatively concentrated position on the sieve plate, so that the expected separation effect is difficult to achieve; the blanking positions are relatively concentrated, so that the effective utilization area of the sieve plate is reduced, the materials falling onto the sieve plate through the feeding box are concentrated near the blanking point and are difficult to reach the parts close to the two sides of the front end of the sieve plate, the materials are unevenly distributed on the sieve plate, the productivity of equipment is wasted, and the sorting efficiency is reduced; an air inlet of the vibrating wind power composite sorting machine is positioned below the sieve plate, and an induced air port or an air outlet is positioned on one side of the end part of the feeding device, so that a wind field in the feeding box is disordered, even backflow wind and whirlwind are formed, light materials needing to be sorted by wind power cannot be effectively discharged from the induced air port or the air outlet, and further the sorting efficiency is low; because outside air supply enters the air inlet box through the straight-through air inlet pipe and is blown upwards to the sieve plate, and no corresponding flow dividing and guiding device is arranged in the sieve plate, the air flow of the outside air supply entering from the air inlet box is too concentrated and cannot be effectively and uniformly dispersed to all positions of the sieve plate, so that local materials of the sieve plate are accumulated, and the separation efficiency is reduced; meanwhile, as the external air supply enters the screen box through the air inlet box and reaches the screen plate, the existence of the air inlet box causes partial wind loss when the external air supply contacts the screen plate, and the efficiency of sorting the materials needing wind power sorting after the wind pressure is reduced is also reduced;

secondly, the fine particles are not easy to collect: the fine particle materials fall to the bottom of the air inlet box through the soft connecting piece and are discharged from the bottom of the air inlet box, and external air supply entering from the air inlet box can generate a blocking effect on the falling of the fine particle materials, even the fine particle materials are blown to the inner wall of the air inlet box, so that the fine particle materials are not easy to collect; meanwhile, the box body of the air inlet box is higher, so that the acting time of external air supply on fine particles is prolonged, the falling time of the fine particles is delayed, and the collection difficulty of the fine particles is increased;

the service life of the sieve plate is reduced: the distribution of the materials on the sieve plate is uneven, and the blanking positions are relatively concentrated, so that concentrated impact and abrasion are easily caused to local areas of the sieve plate of the sorting machine, and the service life of the sieve plate is obviously shortened;

fourthly, the integral stability of the sorting machine is reduced: the existence of the air inlet box increases the overall height of the sorting machine, raises the gravity center of the sorting machine and reduces the overall stability of the sorting machine;

the installation and maintenance cost and the civil engineering cost are increased: because sieve incasement portion does not have the gas locking and arranges material mechanism, in order to guarantee the inside atmospheric pressure of sieve incasement portion and discharge fine particle material, need install two-way screw conveyer and star type ash discharge valve in air inlet bottom of the case portion, this makes and the maintenance cost increase of sorter, has also increased the whole height of sorter simultaneously for the civil engineering cost of factory building etc. increases.
