[0042] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0043] In the description of the present invention, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "up", "down", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "end", "head" and "tail" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solution of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0044] When the cyclone separator is started, a large amount of medium loss and slowing down of the leg surge will occur, which will cause the wing valve port to be over-opened. To solve this problem, the present application proposes a wing valve that can control the over-opening of the discharge port, which is as follows;

[0045] For reference Figure 1-3 The present application is mainly composed of a material pipe 1 connected to the outlet end of the lower part of the material leg of the cyclone separator, a fixing part 2 arranged on the material pipe 1, a hanging part 3 for connecting the protective part 5 and then the folding wing plate 4, and a supporting part 6 for buffering and guiding flow; through the coordination between the structures, the problem of the wing valve opening being too large can be effectively reduced.

[0046] For reference Figure 1-2 The material pipe 1 includes a straight pipe 11 and an inclined pipe 12. The straight pipe 11 is vertically connected to the material leg of the cyclone separator; the inclined pipe 12 is connected and arranged at the bottom of the straight pipe 11, and the lower end is a vertical cut, and the cut surface is matched with the surface of the folding wing plate 4;

[0047] In order to support the material pipe 1 and form a buffer for the material flowing out of the material pipe 1, a bent support member 6 is arranged at the bottom of the material pipe 1. The bending curvature of the support member 6 is not limited and is set based on the on-site installation situation; the support member 6 includes a support beam 61 and a guide plate 62, and the guide plate 62 is arranged on the surface of the support beam 61; the support beam 61 is bent and adapted to be arranged at the bottom of the surface of the inclined pipe 12; when the material flows out of the material pipe 1, the material is hit onto the guide plate 62 and flows through the setting direction of the guide plate 62.

[0048] For reference Figure 1-2 A fixing part 2 is provided at one end of the material pipe 1 close to the material leg of the cyclone separator, and a hanging part 3 is installed and connected with a folding wing plate 4 through the fixing part 2, so that under the impact of pressure, the folding wing plate 4 rotates in an arc on the hanging part 3, so that the material outlet at the lower end of the material pipe 1 blocked by the folding wing plate 4 is discharged;

[0049] Among them, the fixing member 2 includes a support block 21 and an L-shaped plate 22; the support block 21 is fixedly connected to the material tube 1, because it is convenient to set the upper surface of the support block 21 in a horizontal state when connecting the L-shaped plate 22; because the L-shaped plate 22 is set in an L-shape, the L-shaped plate 22 has a transverse horizontal plane and a vertical horizontal plane, and the transverse horizontal plane of the L-shaped plate 22 fits on the support block 21 and is fixed by bolts; when installing the transverse horizontal plane of the L-shaped plate 22, it is necessary to make the vertical horizontal plane of the L-shaped plate 22 facing the material tube 1 correspond to the cross-sectional surface of the lower part of the inclined tube 12, so that when the L-shaped plate 22 is connected to the folding wing plate 4 through the hanger 3, the side of the folding wing plate 4 facing the inclined tube 12 fits with the cross-sectional surface of the inclined tube 12.

[0050] Furthermore, in order to reduce the stability of the arc movement after the L-shaped plate 22 is connected to the folding wing plate 4, the hanger 3 is further designed; the hanger 3 includes a hanging ring 31 and two cylindrical pins 32, and a cylindrical pin 32 is set on the L-shaped plate 22 and the folding wing plate 4, and the L-shaped plate 22 and the folding wing plate 4 are connected together by inserting the hanging ring 31 into the inner holes of the two cylindrical pins 32; in order to further promote the smoothness of the hanging ring 31 during movement, the surface of the hanging ring 31 is polished.

[0051] For reference Figure 1-2 When the lifting ring 31 moves to reduce the resistance, the flexibility of movement will be increased; but it will also relatively increase the opening distance between the folding wing plate 4 and the cross section of the inclined tube 12. In order to further control this problem, a protective member 5 is provided on the folding wing plate 4 to control the problem of the folding wing plate 4 opening speed being too fast or too large.

[0052] The protective member 5 includes a short U-shaped plate 51, at least one sliding shaft 52 and a long U-shaped plate 53; at both ends; a short U-shaped plate 51 is fixedly connected to the surface of the folding wing plate 4, and a long U-shaped plate 53 is located at the lower side of the inclined tube 12 and fixedly connected to the support member 6 corresponding to the short U-shaped plate 51 above and below; the two ends of the sliding shaft 52 are connected to the long U-shaped plate 53 and the short U-shaped plate 51 through a rotating shaft, when the folding wing plate 4 receives a pressure shock, the short U-shaped plate 51 is driven to move, and is restrained by the sliding shaft 52 during the movement, so as to reduce the folding wing plate 4 from opening too fast and too large;

[0053] For reference Figure 3 , the sliding shaft 52 is further optimized, and the sliding shaft 52 includes an A plate 521, a B plate 522, a return spring 523 and a fixing rod 524; the A plate 521 is slidably connected to the B plate 522, and the sliding range can meet the moving range of the folding wing plate 4, and at the same time limit the maximum moving range of the folding wing plate 4; at the same time, in order to speed up the closing effect of the A plate 521 and the B plate 522 when closing, a return spring 523 is arranged inside the A plate 521, and the return spring 523 passes through the inner wall of the A plate 521 and is connected to the B plate 522; thus, when the folding wing plate 4 moves under force, the B plate 522 moves upward, pulling the return spring 523 upward, and after the force is ended, the return spring 523 returns to its position and drives the B plate 522 to quickly move downward and be completely connected to the A plate 521.

[0054] Based on the above, the maximum movement range of the folding wing plate 4 when it moves under force can be limited, thereby reducing the problem of excessive movement of the folding wing plate 4, resulting in excessive opening and failure of flow control; by stabilizing the movement frequency of the folding wing plate 4, reducing excessive opening leading to equipment overload or medium impact, thereby damaging equipment components, etc.

[0055] In the utility model, the working steps of the device are as follows:

[0056] 1. First, install the material pipe 1 at the outlet end of the lower part of the material leg of the cyclone separator, and set a support member 6 adapted to the installation environment at the lower part of the material pipe 1;

[0057] 2. Next, install the fixing part 2 corresponding to the cut surface at the bottom of the material tube 1, and then install the hanging part 3 and the folding wing plate 4 in sequence;

[0058] 3. Then, connect the two ends of the protective member 5 to the folding wing plate 4 and the supporting member 6 respectively;

[0059] 4. Finally, when the cyclone separator moves, the folding wing plate 4 is prompted to rotate along the arc of the hanging piece 3. During the movement of the folding wing plate 4, the protective member 5 controls the folding wing plate 4 from moving too much or too fast along the hanging piece 3, so that the material flows out from the bottom of the material pipe 1 and is driven into the supporting member 6 and flows out.

[0060] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
