Description

Technical Field

[0001] This application belongs to the field of sorting equipment, and in particular relates to a high-efficiency air classifier. Background Technology

[0002] In material processing and handling, air classifiers, as an important separation device, are widely used in industries such as grain, mining, and chemicals. However, existing air classifiers often suffer from low separation efficiency, complex structures, and inaccurate material classification. Especially when handling mixtures containing dust, waste, and large particles, existing equipment cannot effectively separate materials of different particle sizes, easily leading to resource waste and environmental pollution. Therefore, it is necessary to solve these technical problems. Utility Model Content

[0003] The purpose of this application is to provide a high-efficiency air separator to solve the technical problem of low sorting efficiency in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a high-efficiency air classifier, comprising:

[0005] The frame housing has a horizontally arranged feeding channel, waste channel, and dust channel. Each of the feeding channel, waste channel, and dust channel has an opening at its top and bottom along its respective height. The frame housing also forms a conical diffusion cavity and a feeding channel and a blowing channel that are respectively connected to the feeding channel. The top opening of the waste channel is connected to the small opening of the diffusion cavity, and the top openings of the feeding channel and the dust channel are connected to the large opening of the diffusion cavity. The connection port between the feeding channel and the feeding channel is further away from the bottom opening of the feeding channel than the connection port between the blowing channel and the feeding channel.

[0006] An air supply impeller is rotatably mounted on the frame housing and used for air supply. The end of the air blowing channel away from the material feeding channel is connected to the air outlet of the air supply impeller.

[0007] An electric motor is connected to the air supply impeller and is used to drive the air supply impeller.

[0008] Optionally, the side wall of the feeding channel opposite to the blowing channel is arched in an arc shape away from the blowing channel. The blowing channel is used to blow the air provided by the air supply impeller upward at a set angle toward the arc-shaped side wall into the feeding channel.

[0009] Optionally, the arcuate sidewall of the unloading channel extends to intersect with the feeding channel.

[0010] Optionally, the frame housing also forms a sequentially connected lifting channel and an arc-shaped channel, and the top opening of the unloading channel is connected to the diffusion cavity through the lifting channel and the arc-shaped channel;

[0011] The connection port between the feeding channel and the unloading channel is located between the unloading channel and the lifting channel. The end of the lifting channel near the unloading channel forms a tapered port with its large end facing the unloading channel. The edge of the tapered port corresponding to the arc-shaped sidewall is further away from the unloading channel in the horizontal direction from the intersection of the arc-shaped sidewall and the feeding channel.

[0012] Optionally, the high-efficiency air separator further includes an adjustable baffle disposed within the diffusion cavity;

[0013] The adjustable baffle, in conjunction with the inner wall of the diffusion cavity, forms a waste collection port that connects the diffusion cavity to the waste channel and a dust collection port that connects the diffusion cavity to the dust channel.

[0014] The adjustable baffle is also rotatably mounted on the frame housing and can adjust the opening of the waste collection port and the dust collection port during rotation relative to the frame housing.

[0015] Optionally, a conical air-gathering cavity is also formed inside the frame housing;

[0016] The blowing channel is connected to the air outlet of the air supply impeller through the air gathering cavity. The blowing channel is connected to the small end of the air gathering cavity, and the air supply impeller is connected to the large end of the air gathering cavity.

[0017] Optionally, the high-efficiency air separator also includes a finished product conveyor belt, a waste conveyor belt, and a dust collection box;

[0018] The finished product conveyor belt is located directly below the unloading channel, the waste conveyor belt is located directly below the waste channel, and the dust collection box is located directly below the dust channel.

[0019] Optionally, the high-efficiency air classifier also includes a jack, a support rod, and a vibratory feeder for vibratory feeding;

[0020] The jack is connected to the frame housing. One end of the support rod is connected to the power end of the jack, and the other end is hinged to the frame housing. The vibrating feeder is connected to the support rod, and the discharge port of the vibrating feeder is adapted to the feeding channel.

[0021] Optionally, the vibrating feeder is equipped with a paddle for breaking up the target material inside its hopper.

[0022] Optionally, the high-efficiency air separator further includes a door panel slidably connected to the frame housing;

[0023] The door panel, together with the frame housing, forms an adjustable observation window that facilitates observation of the working conditions inside the housing.

[0024] The beneficial effects of the high-efficiency air classifier provided in this application are as follows: Compared with the prior art, in the high-efficiency air classifier provided in this application, the air supply impeller can be driven by a motor and blow air into the discharge channel through the air blowing channel. Since the connection port between the feed channel and the discharge channel is farther away from the bottom opening of the discharge channel than the connection port between the air blowing channel and the discharge channel, when the target mixture enters the discharge channel from the feed channel and falls along the discharge channel under the action of gravity, it will meet the air blown into the discharge channel from the air blowing channel. In this way, by adjusting the output of the air supply impeller by the motor to output appropriate air force, the finished material and waste in the target mixture can be separated. The separated finished material can be discharged from the bottom opening of the discharge channel, while the separated waste will rise into the diffusion chamber under the action of air force in the discharge channel. Because the diffusion chamber is conical, the airflow velocity decreases after entering the diffusion chamber. As a result, some of the heavier materials in the waste will automatically enter the waste channel, while the other part of the dust will enter the dust channel under the influence of the remaining airflow. Thus, the high-efficiency air separator provided in this application can efficiently separate target mixtures of different components through the unique air duct design inside the frame housing and the air supply impeller that can adjust the output airflow through the motor, which is far superior to the existing technology.

[0034] Please refer to the following: Figures 1 to 3 The present application provides a description of a high-efficiency air classifier. This high-efficiency air classifier includes a frame housing 100, an air supply impeller 200, and a motor 300. Wherein:

[0035] The frame housing 100 contains a horizontally arranged feeding channel 101, a waste channel 102, and a dust channel 103, all arranged side-by-side. Each of these channels has openings at its top and bottom along its respective height. The frame housing 100 also forms a conical diffusion chamber 104 and feeding channels 105 and 106 connected to the feeding channel 101. The top opening of the waste channel 102 connects to the smaller opening of the diffusion chamber 104. The top opening of channel 103 is connected to the large opening of diffusion cavity 104. The connection port between feed channel 105 and discharge channel 101 is further away from the bottom opening of discharge channel 101 than the connection port between air blowing channel 106 and discharge channel 101. Air supply impeller 200 is rotatably mounted on frame housing 100 and used for air supply. The end of air blowing channel 106 away from discharge channel 101 is connected to the air outlet of air supply impeller 200. Motor 300 is driven by air supply impeller 200 and used to drive air supply impeller 200.

[0036] According to the structure provided in this embodiment, in the high-efficiency air classifier provided in this embodiment, the air supply impeller 200 can be driven by the motor 300 and blow air into the discharge channel 101 through the air blowing channel 106. Since the connection port between the feed channel 105 and the discharge channel 101 is farther away from the bottom opening of the discharge channel 101 than the connection port between the air blowing channel 106 and the discharge channel 101, when the target mixture enters the discharge channel 101 from the feed channel 105 and descends along the discharge channel 101 under the action of gravity, it will converge with the air blown into the discharge channel 101 from the air blowing channel 106. In this way, by adjusting the air supply impeller 200 outputting appropriate air force by the motor 300, the finished material and waste in the target mixture can be separated. The separated finished material can be discharged from the bottom opening of the discharge channel 101, while the separated waste will rise into the diffusion chamber 104 under the action of the air force in the discharge channel 101. Because the diffusion chamber 104 is conical, the air velocity decreases after entering the diffusion chamber 104. As a result, some of the heavier materials in the waste will automatically enter the waste channel 102, while the other part of the dust will enter the dust channel 103 under the influence of the remaining air force. Thus, the high-efficiency air separator provided in this embodiment can efficiently separate target mixtures of different components through the unique air duct design inside the frame housing 100 and the air supply impeller 200 that can adjust the output air force through the motor 300, which is far superior to the existing technology.

[0037] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The side wall of the feeding channel 101 opposite to the blowing channel 106 arches into an arc-shaped side wall in a direction away from the blowing channel 106. The blowing channel 106 is used to blow the air supplied by the impeller 200 upward at a set angle toward the arc-shaped side wall into the feeding channel 101. Here, the angle between the direction of the wind blowing and the vertical direction (the direction in which the target mixture falls naturally) is preferably 30 to 60 degrees, and in a more preferred embodiment, this angle is 50 degrees. According to the structure provided in this embodiment, the finished material separated from the target mixture can descend along the arc-shaped side wall under the action of wind force as it descends in the feeding channel 101 and approaches the blowing channel 106, which can effectively prevent the finished material from entering the blowing channel. At the same time, through the synergistic effect of the arc-shaped side wall structure and the blowing channel 106, wind energy can be fully utilized to perform two sorting of the target mixture. That is, when the wind blows toward the target mixture for the first time for the first wind force sorting, the finished product descends along the feeding channel 101, while the waste... The material and dust are lifted into the lifting channel 107. After the air passes through the target mixture for the first time, it is blocked by the arc-shaped sidewall and blows back up along the arc-shaped sidewall to the target mixture at the intersection of the material channel 101 and the feed channel 105. This is equivalent to the initial sorting of the target mixture. In addition, the guiding effect of the arc-shaped sidewall can effectively guide the air, waste material and dust into the lifting channel 107, preventing the air, waste material and dust from entering the feed channel 105. This is also conducive to further improving the sorting efficiency of the high-efficiency air classifier in this embodiment.

[0038] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The arc-shaped sidewall of the discharge channel 101 extends to intersect with the feed channel 105. According to the structure provided in this embodiment, the extension of the arc-shaped sidewall of the discharge channel 101 to intersect with the feed channel 105 helps guide the airflow within the discharge channel 101 and directs the airflow away from the feed channel 105. This effectively prevents waste separated from the target mixture from entering the feed channel 105, thereby further improving the sorting efficiency of the high-efficiency air classifier in this embodiment.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3Inside the frame housing 100, a sequentially connected lifting channel 107 and an arc-shaped channel 108 are formed. The top opening of the discharge channel 101 is connected to the diffusion chamber 104 through the lifting channel 107 and the arc-shaped channel 108. The connection port between the feed channel 105 and the discharge channel 101 is located between the discharge channel 101 and the lifting channel 107. The end of the lifting channel 107 near the discharge channel 101 forms a tapered port with its larger end facing the discharge channel 101. The edge of the side wall corresponding to the tapered port and the arc-shaped side wall is further away from the discharge channel 101 in the horizontal direction from the intersection of the arc-shaped side wall and the feed channel 105. According to the structure provided in this embodiment, the connected lifting channel 107 and arc-shaped channel 108 facilitate the smoother introduction of waste separated from the target mixture into the diffusion chamber 104. In addition, since the end of the lifting channel 107 near the feeding channel 101 forms a tapered port with the large end facing the feeding channel 101, and the edge of the side wall corresponding to the tapered port and the arc side wall is further away from the feeding channel 101 in the horizontal direction relative to the intersection of the arc side wall and the feeding channel 105, this is beneficial to allow the waste to enter the lifting channel 107 more fully, and can further prevent the waste separated from the target mixture and the wind from entering the feeding channel 105, thereby also helping to further improve the sorting efficiency of the high-efficiency air classifier in this embodiment.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The high-efficiency air classifier also includes an adjustable baffle 400 disposed within the diffusion chamber 104. The adjustable baffle 400, in conjunction with the inner wall of the diffusion chamber 104, forms a waste collection port 109 connecting the diffusion chamber 104 to the waste channel 102 and a dust collection port 110 connecting the diffusion chamber 104 to the dust channel 103. The adjustable baffle 400 is also rotatably mounted on the frame housing 100 and can adjust the opening degree of the waste collection port 109 and the dust collection port 110 during rotation relative to the frame housing 100. According to the structure provided in this embodiment, the adjustable baffle 400, rotatably disposed within the diffusion chamber 104, can adjust the opening degree of the waste collection port 109 and the dust collection port 110 by rotation. This allows the opening size of the waste collection port 109 and the dust collection port 110 to be more suitable to the component proportions in the target mixture, thus further improving the separation efficiency of the high-efficiency air classifier in this embodiment.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The frame housing 100 also forms a conical air-gathering cavity 111 inside; the air-blowing channel 106 is connected to the air outlet of the air-supplying impeller 200 through the air-gathering cavity 111, with the air-blowing channel 106 connected to the small end of the air-gathering cavity 111 and the air-supplying impeller 200 connected to the large end of the air-gathering cavity 111. According to the above structure provided in this embodiment, the conical air-gathering cavity 111 can be used to concentrate the air and significantly increase the air force, which is beneficial to further improve the sorting efficiency of the high-efficiency air classifier in this embodiment.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The high-efficiency air classifier also includes a finished product conveyor belt 501, a waste conveyor belt 502, and a dust collection box 503. The finished product conveyor belt 501 is located directly below the discharge channel 101, the waste conveyor belt 502 is located directly below the waste channel 102, and the dust collection box 503 is located directly below the dust channel 103. According to the structure provided in this embodiment, the finished product conveyor belt 501 located directly below the discharge channel 101 can be used to promptly transfer finished materials, the waste conveyor belt 502 located directly below the waste channel 102 can be used to promptly transfer heavier waste materials, and the dust collection box 503 located directly below the dust channel 103 can be used to collect dust from the waste materials. This is beneficial for further improving the sorting efficiency of the high-efficiency air classifier in this embodiment.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The high-efficiency air classifier also includes a jack 601, a support rod 602, and a vibrating feeder 603 for vibrating feeding. The jack 601 is connected to the frame housing 100. One end of the support rod 602 is connected to the power end of the jack 601, and the other end is hinged to the frame housing 100. The vibrating feeder 603 is connected to the support rod 602, and the discharge port of the vibrating feeder 603 is adapted to the feed channel 105. According to the structure provided in this embodiment, the vibrating feeder 603 can uniformly convey the target mixture to the feed channel 105 by the operation of the vibrating motor 300 during operation. The jack 601 connected to the frame housing 100 can change the tilt angle of the vibrating feeder 603 by driving the support rod 602 to rotate, which can adjust the feeding speed of the material and further improve the sorting efficiency of the high-efficiency air classifier in this embodiment.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The vibrating feeder 603 has a hopper equipped with a paddle 604 for breaking up the target material. According to the structure provided in this embodiment, the paddle 604 in the hopper of the vibrating feeder 603 can effectively break up the target mixture, which helps to further improve the sorting efficiency of the high-efficiency air classifier in this embodiment.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The high-efficiency air classifier also includes a door panel 701 slidably connected to the frame housing 100; the door panel 701, together with the frame housing 100, forms an adjustable observation window 702 that facilitates observation of the internal working conditions. According to the structure provided in this embodiment, the observation window 702 formed by the door panel 701 and the frame housing 100 allows operators to easily observe the internal working conditions, which is beneficial for timely troubleshooting or maintenance, and thus also helps to further improve the sorting efficiency of the high-efficiency air classifier in this embodiment.
