Technical Field

[0001] The utility model relates to the technical field of air separation and dust removal, in particular to an energy-saving and environment-friendly dust removal air separation machine. Background Art

[0002] Dust removal and air separation is a common dust removal technology. Its principle is mainly to use the difference in aerodynamic characteristics between dust and solid particles to achieve effective separation of different components in the material. In solid dust removal and air separation, the main purpose of airflow control is to adjust the airflow speed and direction to better achieve effective separation of dust and solid particles.

Different air volumes need to be controlled for different dust particles to be screened. When the air blowing is uneven, it is very easy to cause incomplete separation between dust and solid particles.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] This embodiment is used to solve the problem that single-channel air blowing dust removal causes dust to spread and cannot completely remove dust, ultimately resulting in incomplete separation of dust and solid particles.

[0031] See also Figure 1 - Fig. 9 As shown, this embodiment is an energy-saving and environmentally friendly dust-removing air separator, comprising a frame 1, an air separation box 3, an exhaust box 4 and a screening mechanism 7. The air separation box 3 is arranged on the upper side of the end of the frame 1, and the exhaust box 4 is arranged on the upper side of the other end of the frame 1. The side of the air separation box 3 close to the exhaust box 4 is connected with a dust removal box 5, and the bottom of the frame 1 away from the air separation box 3 is equipped with a conveyor belt 2; a feeding hopper 301 is installed on the top of the air separation box 3, and an air separation plate frame 303 is installed inside the air separation box 3. The air separation plate frame 303 includes multiple groups of vertical plates to form a through gap, and spoilers 309 are arranged between the spaced vertical plates. A symmetrically arranged exhaust port 308 is opened on one side of the air separation plate frame 303 corresponding to the dust removal box 5, a sliding cover plate 402 is movably installed on the top of the exhaust box 4, a fan 401 is symmetrically installed on the outside of the exhaust box 4, and filter cartridges 403 arranged evenly are installed inside the exhaust box 4. The bottom of the exhaust box 4 is connected with a dust accumulation hopper 404;

[0032] An impeller 304 is rotatably mounted between the middle parts of the vertical plates on the air separation plate frame 303, a baffle 306 is rotatably mounted at the bottom of the air separation plate frame 303, a collecting opening is provided at the bottom of the air separation box 3 corresponding to the air separation plate frame 303 and is aligned with the top of the screening mechanism 7, the inner bottom end of the dust removal box 5 is inclined, a partition 501 is installed near the inner top end of the dust removal box 5, and a feeding spiral blade 502 is installed at the bottom of the dust removal box 5;

[0033] A connecting box 6 is installed between the dust removal box 5 and the exhaust box 4. A plurality of filter screens are arranged in the connecting box 6. The connecting box 6 is connected to the top of the dust removal box 5. The connecting box 6 is connected to the inside of the dust hopper 404. A rotating motor 302 is installed on the outside of the air separation box 3. A bearing seat 307 is installed on the outer end of the air separation box 3 which is rotatably connected to the impeller 304. The rotating motor 302 is respectively connected to the impeller 304 through a pulley drive.

[0034] A rotating rod is installed on the baffle 306, and a rotating handle 305 is installed on the outer end of the rotating rod extending to the winnowing box 3. The opening angle of the baffle 306 is adjusted by the rotating handle 305, that is, the size of the passing gap is controlled, so as to quickly limit the passing size of the rice particles;

[0035] See also Figure 1 — Figure 6 As shown, when the rice is dusted and air-selected, the fan 401 is first turned on, and the fan 401 draws air to form a wind flow direction from the air selection box 3 → the dust removal box 5 → the connecting box 6 → the dust hopper 404 → the filter cartridge 403 in the air extraction box 4, and then the rice is poured into the air selection box 3 through the inlet hopper 301. According to the preliminary determination of the required rice particle size, the size of the passing gap between the turning handle 305, the baffle 306 and the vertical plate on the air selection plate frame 303 is manually adjusted. After the rice falls on the air selection plate frame 303, it is first hit by the spoiler 309. Combined with the wind flow direction of the air extraction, the rice presents a complex movement trajectory between the air selection plate frames 303, so that the husks and dust mixed between the rice particles are drawn into the dust removal box 5 from the air extraction port 308 by the wind flow, and the normal rice particles fall from the collecting port to the screening mechanism 7 below;

[0036] When the husks and dust enter the dust removal box 5, they are first blocked by the partition 501. The husks are not directly driven into the connecting box 6 by the wind flow, but are blocked again by the filter screen on the connecting box 6 and fall to the feeding spiral blade 502 below, and are sent out and collected by the continuously rotating feeding spiral blade 502; at the same time, the dust enters the exhaust box 4 through the connecting box 6, and adheres to the filter cartridge 403 or accumulates in the dust hopper 404. The filter cartridge 403 here must be cleaned or replaced regularly to provide a better filtering effect and prevent damage to the fan 401. In summary, the air separator can continuously extract dust and husks in the direction of wind flow to prevent dust diffusion, and the coordinated use of the spoiler 309 and the impeller 304 makes the rice present an irregular movement trajectory, so that the husks and dust contained in the rice particles are completely screened out to achieve the purpose of complete separation.

[0037] Embodiment 2:

[0038] This embodiment is based on the solid particles after air separation in the first embodiment, and reclassifies the solid particles through a multi-stage screening structure, so as to obtain the required specifications and complete the collection, as follows:

[0039] See also Figure 4 , Figure 7 - Fig. 9 As shown, an energy-saving and environmentally friendly dust removal air separator of this embodiment includes a screening mechanism 7 including a screen frame and a screen plate 703 with gradually smaller filter holes, and the screen frame is respectively provided with a discharge box 1 704, a discharge box 2 705 and a discharge box 3 706 on the bottom side corresponding to each screen plate 703;

[0040] Vibration motors 702 are installed in the middle of both sides of the screen frame on the screening mechanism 7, and shock-absorbing seats 701 are installed at the four corners of the outer side of the screen frame. The shock-absorbing seats 701 are connected to the frame 1. The conveyor belt 2 is tilted at the bottom of the frame 1. The bottom of the conveyor belt 2 is aligned with the opening of the second discharge box 705. When the qualified rice particles are discharged from the second discharge box 705, they fall into the hopper on the conveyor belt 2 to complete accurate collection;

[0041] See also Figure 7 - Fig. 9As shown, after normal rice grains fall from the collecting port to the screening mechanism 7 below, they first fall to the top of the screen frame on the screening mechanism 7, and the vibration motor 702 is started to drive the screen frame to shake continuously. The inclined screen frame on the frame 1 can vibrate and screen the rice particles on the top, and large rice particles are retained on the top screen plate 703, medium rice particles fall on the middle screen plate 703, and small rice particles fall on the bottom screen plate 703. The rice particles on the screen plates 703 at different levels are discharged from top to bottom by the discharge box 1 704, the discharge box 2 705 and the discharge box 3 706 respectively, and the collection is completed. The medium rice particles (i.e., qualified rice) are discharged to the hopper on the conveyor belt 2 through the discharge box 2 705, and the transportation and centralized collection are completed.

[0042] Combining Example 1 and Example 2, the continuously pumping wind direction and the complex movement trajectory of the rice particles can be utilized to achieve comprehensive screening of dust and husks in the rice particles and to separate them completely, and the screening mechanism can be used to complete the graded screening of the rice particles and accurately collect qualified particles, which complies with the collection of rice particles by grade and avoids dust diffusion, saves energy and protects the environment, and improves the efficiency of rice impurity removal.

[0043] The process and principle of this utility model are as follows:

[0044] Step 1: When performing dust removal and air selection of rice, first turn on the fan 401, and the fan 401 draws air to form a wind flow direction from the air selection box 3 → dust removal box 5 → connection box 6 → dust hopper 404 → filter cartridge 403 in the air extraction box 4, and then pour the rice into the air selection box 3 through the feed hopper 301;

[0045] Step 2: According to the preliminary determination of the required rice grain size, manually adjust the clearance between the turning handle 305, the baffle 306 and the vertical plate on the air separation plate frame 303. After the rice falls on the air separation plate frame 303, it is first hit by the spoiler 309. Combined with the wind direction of the exhaust, the rice presents a complex movement trajectory between the air separation plates 303, so that the husks and dust mixed between the rice grains are drawn into the dust removal box 5 from the exhaust port 308 by the wind flow, and the normal rice grains fall from the collecting port to the screening mechanism 7 below;

[0046] Step 3: After the husks and dust enter the dust removal box 5, they are first blocked by the partition 501. The husks are not directly driven into the connection box 6 by the wind flow, but are blocked again by the filter screen on the connection box 6 and fall to the feeding spiral blade 502 below, and are sent out and collected by the continuously rotating feeding spiral blade 502.

[0047] Step 4: After normal rice grains fall from the collecting port onto the screening mechanism 7 below, they first fall onto the top of the screen frame on the screening mechanism 7, and the vibration motor 702 is started to drive the screen frame to shake continuously, and large rice grains are retained on the top screen plate 703, medium rice grains fall onto the middle screen plate 703, and small rice grains fall onto the bottom screen plate 703, and the rice grains on the screen plates 703 at different levels are discharged from top to bottom by the discharge box 1 704, the discharge box 2 705 and the discharge box 3 706, and the collection is completed, wherein the medium rice grains (i.e., qualified rice) are discharged to the hopper on the conveyor belt 2 through the discharge box 2 705, and the transportation and centralized collection are completed:

[0048] To sum up: the winnowing machine can make the rice particles form a complex movement trajectory through the continuous pumping wind flow direction, realize the comprehensive screening of dust and husk in the rice particles, and can completely separate them. It can also use the screening mechanism to complete the graded screening of rice particles and accurately collect qualified particles, which complies with the collection of rice particles by grade, avoids dust diffusion, saves energy and is environmentally friendly, and improves the efficiency of rice impurity removal.
