[0037] The utility model will be explained in further detail in combination with the drawings. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so that they only show the structure related to the utility model, the direction and the reference (such as up, down, left, right, etc.) can be only used to help the description of the features in the drawings. Therefore, the following detailed description is not in the restrictive sense, and the scope of the claimed subject matter is only limited by the appended claims and their equivalents.

[0038] As shown in Figure 1 and Figure 2 , a self-cleaning gas-material separator comprises a separation shell 1, a separation rotating screen 2 and a self-cleaning assembly.

[0039] The separation shell 1 is roughly in the shape of a vortex shell, and has a separation cavity 101 formed inside, and a gas-material mixture inlet 102, a material outlet 103 and a gas outlet 104 in communication with the separation cavity 101. Specifically, the gas-material mixture inlet 102 is located at the top and is tangentially arranged, the material outlet 103 is located at the bottom, and the gas outlet 104 is located between the gas-material mixture inlet 102 and the material outlet 103;

[0040] The separation rotating screen 2 is rotationally arranged in the separation cavity 101 and is opposite to the gas outlet 104. When the separation rotating screen 2 rotates, relative movement occurs between the separation rotating screen 2 and the cavity wall of the separation cavity 101, so that blockage between the two can be avoided.

[0041] The self-cleaning assembly is fixed in the separation cavity 101 to clean the surface of the separation rotating screen 2 when relative rotation occurs with the separation rotating screen 2.

[0042] The mixture enters the separation cavity 101 from the gas-material mixture inlet 102 in a tangential direction, and gas-material separation is performed in the separation cavity 101. The gas is discharged from the gas outlet 104 after passing through the separation rotating screen 2, and the material is discharged from the material outlet 103 under the action of gravity. The rotationally arranged separation rotating screen 2 can avoid blockage between the separation rotating screen 2 and the cavity wall of the separation cavity 101, and the self-cleaning assembly can clean the surface of the separation rotating screen 2 during the rotation of the separation rotating screen 2, so that poor gas discharge caused by blockage of the separation rotating screen 2 can be avoided.

[0043] In some examples, as shown in Figure 1 and Figure 5 The separation rotating screen 2 assembly further includes a rotating drive mechanism 3 for driving the separation rotating screen 2 to rotate. The rotating drive mechanism 3 is covered by a protective cover 10, which can isolate the gas and material to improve the service life of the rotating drive mechanism 3. The rotating drive mechanism 3 can be installed outside the separation shell 1 to form an external structure, or can be installed inside the separation shell 1 to form an internal structure.

[0044] In some examples, as shown in Figure 3 The separation rotating screen 2 includes a cylindrical filter screen 201, a main shaft 203 axially arranged inside the filter screen 201, and a skeleton disc 202 connected between the main shaft 203 and the filter screen 201. An inner transparent cover 4 is fixed at a position opposite to the gas outlet 104 of the separation shell 1. The two ends of the main shaft 203 are arranged on and rotationally connected to the inner transparent cover 4. The inner transparent cover 4 is in a hollow structure and specifically includes an inner ring, an outer ring, and a plurality of circumferentially distributed ribs fixed between the inner ring and the outer ring. The two ends of the main shaft 203 pass through the inner ring and can rotate in the inner ring. The number of skeleton discs is at least two and is spaced apart along the axial direction of the main shaft 203 to fix the filter screen 201 and the main shaft 203.

[0045] In some examples, as shown inFigure 4 As shown, a self-lubricating support mechanism 5 is provided between the main shaft 203 and the inner cover 4. It includes an end cover 501 installed at the end of the main shaft 203, a sealing cover 502 spaced apart from the end cover 501, a bearing seat 503 connected between the end cover 501 and the sealing cover 502, and a self-lubricating bearing 504 installed on the bearing seat 503. The main shaft 203 passes through the sealing cover 502 and a sealing ring 506 is installed between the two. The end cover 501, the bearing seat 503 and the sealing cover 502 enclose a mounting cavity for the self-lubricating bearing 504. An over-positioning ring 505 is installed between the bearing seat 503 and the self-lubricating bearing 504.

[0046] In some examples, such as Figure 6 As shown, a guide plate 6 is provided on the upstream side of the separation rotating mesh 2 along the flow direction of the mixture to guide the mixture entering from the gas-material mixture inlet 102 to the separation rotating mesh 2, which can prevent the material from being discharged from the gas outlet 104 and causing material leakage.

[0047] In some examples, such as Figure 6 As shown, the guide plate 6 is inclined, with one end fixed to the separation shell 1 and the other end having a gap with the separation rotating net 2 to avoid interference with the rotation of the separation rotating net 2. Due to the existence of this gap, material will leak out from the gap, resulting in material loss. Therefore, a clamp 7 is sleeved on the end of the separation rotating net 2. A sealing element 8 for intercepting the mixture from the gap is installed between the clamp 7 and the inner wall of the separation shell 1. One end of the sealing element 8 along its axial direction is pressed by the clamp 7, and the other end is sleeved on the inner transparent cover 4 to form a sealing structure.

[0048] In some examples, such as Figure 1 As shown, there are two gas outlets 104 and two material outlets 103. The two gas outlets 104 are located on both sides of the separating rotating mesh 2 along its axial direction. Each gas outlet 104 is inclined downward along the flow path to accelerate gas discharge. The two material outlets 103 are arranged side by side, and their cross-sectional area gradually decreases along the material flow path.

[0049] In some examples, such as Figure 1 As shown, the self-cleaning component includes a scraper 9, or a brush roller or compressed air pulse jet. The scraper 9 extends along the axial direction of the separating rotating net 2 and both ends are fixed to the cavity wall of the separating chamber 101. The axial extension length of the scraper 9 is approximately equal to the axial extension length of the separating rotating net 2, so as to clean the entire length of the separating rotating net 2.

[0050] In some examples, such as Figure 5As shown, the rotary drive mechanism 3 includes a driver 301, a drive wheel 302 connected to the driver 301, a driven wheel 303 connected to the separate rotating net 2, and a synchronous belt 304 connected between the driven wheel 303 and the drive wheel 302. The driver 301 is a motor. When the motor is started, it drives the drive wheel 302 to rotate. The drive wheel 302 drives the driven wheel 303 to rotate through the synchronous belt 304. The driven wheel 303 drives the main shaft 203 to rotate. The drive wheel 302, the driven wheel 303, and the synchronous belt 304 are all located inside the protective cover 10 to prevent materials from entering. The protective cover 10 can be an integral structure or a split structure. When it is a split structure, two adjacent protective sub-covers are fixed by flanges.

[0051] In some examples, the timing belt 304 is a chain or belt.

[0052] Working principle:

[0053] The mixture enters the separation chamber 101 tangentially from the gas-material mixture inlet 102, where gas and material are separated. The gas passes through the separation rotating mesh 2 and is discharged from the gas outlets 104 on both sides, while the material is discharged from the material outlet 103 under gravity. At the same time, the motor drives the drive wheel 302 to rotate, which in turn drives the driven wheel 303 to rotate via the synchronous belt 304. The driven wheel 303 drives the separation rotating mesh 2 to rotate. The rotating separation mesh 2 can prevent blockage between itself and the wall of the separation chamber 101. Furthermore, the self-cleaning component can clean the surface of the separation rotating mesh 2 during its rotation, thus preventing obstruction of the separation rotating mesh 2 and hindering gas discharge.
