Examples
Referring to fig. 1 to 3, the present embodiment provides a comprehensive dust-raising type circulating separation system 1000.
The integrated dust-raising type circulation separation system 1000 includes: a separation chamber 100, a first feed conduit 110 and a second feed conduit 120.
The first and second feed pipes 110 and 120 are both communicated with the upper portion of the separation chamber 100 and outlet ends of the two are disposed opposite to each other. The discharge channel 130 of the separation chamber 100 is also located at the upper part thereof. The bottom of the separation chamber 100 is provided with a blanking port 140 through which coarse material falls.
In the use process, the materials to be separated are blown into the separation chamber 100 through the first feeding pipeline 110 and the second feeding pipeline 120 by air flow, and the material particles with smaller granularity are lighter, so that the materials can smoothly leave the separation chamber 100 through the discharging channel 130 at the upper part of the separation chamber 100 under the action of the air flow.
For the material particles with larger granularity, the weight is larger, the airflow has certain diffusivity after entering the separation chamber 100, the material particles with larger granularity can fall to the bottom of the separation chamber 100 and finally fall out from the blanking port 140, and the separation and screening of coarse and fine materials are realized.
Wherein, the air current carries the material granule to divide two strands into the separation chamber 100 through first feeding pipeline 110 and second feeding pipeline 120, because first feeding pipeline 110 and second feeding pipeline 120 all communicate with the upper portion of separation chamber 100 and the exit end of two sets up in opposite directions, two air currents are the form entering separation chamber 100 that collides, in the collision in-process, have certain crushing effect to the material granule, promote unstable coarse fodder to disintegrate, avoid influencing subsequent use. Meanwhile, the device has a further disturbing effect on material particles in the air flow, so that fine materials can be effectively prevented from being adhered to the surface of coarse materials and falling together, and the separation sufficiency is greatly improved.
In addition, in the collision process, the surface of the material particles is further helped to be polished, so that the material particles are more regular, and the material quality is improved.
Overall, the comprehensive dust-raising type circulating separation system 1000 has novel structure, high operation efficiency, simple operation, wide application range and environmental protection. The device effectively improves the separation capacity and improves the separation effect.
It should be noted that, a grid (or filter plate) with a specific aperture may be disposed in the discharge channel 130, so as to avoid the coarse material being carried out by the air flow.
In this embodiment, the first feeding pipe 110 and the second feeding pipe 120 are arc pipes, and the centers of the arcs corresponding to the two pipes are located on opposite sides of the two pipes. The circular arcs corresponding to both the first and second feed pipes 110 and 120 are located on the same circumference. By this design, the clash effect and the separation effect are further improved.
Further, a fan 200 is further disposed in the separation chamber 100, and the fan 200 is rotatably mounted in the separation chamber 100 by a rotating shaft. The fan blade 200 is disposed adjacent to the discharge passage 130. The rotation axis is arranged in the lateral direction of the separation chamber 100, and the planes in which the central axes of both the first and second feed pipes 110 and 120 are located are also arranged in the lateral direction of the separation chamber 100. The outlet ends of both the first and second feed conduits 110, 120 are facing the fan blade 200 at the same time.
Through the design, the air flow collides with the fan blades 200, and meanwhile, the air flow is blown to the fan blades 200, so that the fan is passively rotated, the air flow can be disturbed more effectively along with the rotation of the fan, and coarse materials and fine materials contacted with the fan blades 200 can be pushed. In this embodiment, the air flow is controlled to blow toward the upper half of the fan blade 200 so that the material particles are pushed toward the top of the separation chamber 100 during the rotation of the fan.
This greatly increases the residence time of the material particles in the separation chamber 100 (particularly near the fan), promoting adequate separation of the coarse and fine material, and at the same time avoiding excessive coarse material drop rates and reduced fine material carry-over.
In this embodiment, the inner wall of the separation chamber 100 is provided with a diversion platform 300, and the diversion platform 300 is located below the discharge channel 130 and is disposed on a side wall of the discharge channel 130. The guide table 300 has a guide wall 310, the guide wall 310 is arc-shaped, and a cylindrical wall corresponding to the guide wall 310 is coaxially arranged with the rotating shaft. The distance between the guide wall 310 and the sidewall of the separation chamber 100 increases in the height direction and downward direction of the separation chamber 100.
Through the design, the diversion bench 300 can utilize the diversion wall 310 to dredge the material particles, so that the material particles are prevented from being scattered due to excessively strong turbulence, the coarse material particles are prevented from being impacted forcefully to a certain extent (particularly, the impact strength between the material particles and the fan blade 200 is reduced), and the loss of the fan blade 200 and the inner wall of the separation chamber 100 is greatly reduced.
Further, the integrated dust-raising type circulating separation system 1000 further includes: coarse feed pipe 400, pulverizing assembly 500, and return pipe 600. The coarse material pipe 400 is communicated with the blanking port 140 and arranged along the height direction, and the coarse material pipe 400 is communicated with an inlet of the crushing assembly 500, and is used for guiding coarse material into the crushing assembly 500 (such as a crusher, but not limited thereto) for crushing, so that the coarse material is converted into fine material. The return pipe 600 communicates with the outlet of the pulverizing assembly 500 for receiving pulverized fine material, and the other end of the return pipe 600 communicates with the separation chamber 100. The return pipe 600 is provided with a blower assembly for blowing pulverized material back to the separation chamber 100. The blower assembly communicates with the return pipe 600 through a blower pipe 620.
Coarse material falling from the separation chamber 100 enters the coarse material pipe 400 through the blanking port 140, moves downwards along the discharging pipe until the crushing assembly 500 is crushed into fine material, and the crushed material enters the return pipe 600 and is blown back to the separation chamber 100 again by the blast assembly for repeated separation. By this design, the integrated dust-type circulation separation system 1000 can be modified to a device for screening fine materials exclusively, and has a function of pulverizing coarse materials into predetermined fine materials.
The materials can be completely converted into fine materials by repeating the processing through the flow.
In this embodiment, the return pipe 600 communicates with the outlet of the pulverizing assembly 500 using a branch pipe 610, and the branch pipe 610 is disposed near the bottom end of the return pipe 600. The bottom end of the return pipe 600 is provided with a waste collection chamber 700. By this design, by controlling the air force of the air blast assembly, the material particles which still keep large granularity after the crushing processing of the crushing assembly 500 cannot be blown back to the separation chamber 100 and directly fall into the waste collection chamber 700 for collection and processing. Can be used for collecting material particles or impurities which are not easy to be crushed, and also has certain impurity removal and screening capacity for the comprehensive dust-raising type circulating separation system 1000.
Further, the return pipe 600 is indirectly connected to the separation chamber 100 through the coarse feed pipe 400, and the top end of the return pipe 600 is connected to the sidewall of the coarse feed pipe 400 and is connected to the coarse feed pipe 400. By this design, it is also possible to control coarse material falling through the coarse material pipe 400 by controlling the wind power of the blast assembly. The material particles that can be blown back into the separated form by the blast air flow cannot fall smoothly, and only coarse material that can overcome the blast air flow can fall smoothly and enter the pulverizing assembly 500.
By the design, the wind power of the air blast assembly can be adjusted, and the purpose of further controlling the weight of coarse material particles is achieved.
It should be noted that, the separation chamber 100, the first feeding pipe 110 and the second feeding pipe 120 may be provided in plural, and the separation chambers 100 are serially connected through the first feeding pipe 110 and the second feeding pipe. Namely: the first feed conduit 110 and the second feed conduit of the second separation chamber 100 are both in communication with the discharge channel 130 of the first separation chamber 100, and so are repeated in succession.
By this design, multistage separation can be achieved. It is particularly noted that the coarse pipes 400 of the separation chambers 100 may be connected to the same crushing assembly 500 by means of one inclined pipe 800, while the return pipe 600 is connected to only the first separation chamber 100. Thus, the plurality of separation chambers 100 are linked, and the coarse materials can be sufficiently sieved and crushed to a desired particle size while the multi-stage separation is realized.
Of course, it is also possible to match one pulverizing module 500 for each separation chamber 100, and to taper the fineness of pulverization for each pulverizing module 500 in turn. And one return pipe 600 is matched for each separation chamber 100, and the corresponding return pipe 600 is connected only to the separation chamber 100 corresponding thereto. In this way, the crushing capacity of the whole system and the uniformity of the finally obtained material particles can be greatly improved.
The present embodiment also provides a series of dust-raising type circulating separation methods using the integrated dust-raising type circulating separation system 1000, which have been described in detail above and are not described here again.
In summary, the comprehensive dust-raising type circulating separation system 1000 has novel structure, high operation efficiency, simple operation, wide application range, environmental protection, effectively improves the separation capacity and improves the separation effect. The dust-raising type circulating separation method is simple and easy to implement, is convenient for practical operation, effectively improves the separation capacity and improves the separation effect.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
