Description

Technical Field

[0001] This utility model relates to the field of air cannon technology for silos, and in particular to a novel multi-angle adjustment device for air cannons. Background Technology

[0002] During normal production in the blast furnace pulverized coal injection workshop, the coal type changes frequently, the material moisture content is high, the viscosity is high, the silo is severely stuck, and the material sloshing is frequent, causing the material to be discharged unevenly. The existing air cannons have a fixed downward impact angle and cannot be adjusted. Although they can make the blocked material in the raw coal silo flow downward, they do not solve the problem of the sticky material above and the material surrounding the side wall of the silo. The raw coal silo will soon experience the sloshing phenomenon again.

[0003] Utility model patent CN222361410U discloses an air cannon multi-angle adjustment device, including an air cannon body, a raw coal bunker, and a lock belt scale. The air cannon generated by the air cannon body is ejected from the output pipe and then transported to the seamless bend through the built-in pipe. The air cannon is ejected from the seamless bend and acts on the inside of the raw coal bunker to unclog it. By holding the protective sleeve and rotating the built-in pipe, the built-in pipe drives the seamless bend to rotate, which can increase the working range of the seamless bend. However, the above adjustment device can only make the seamless bend rotate along the axis to clear blockages in the vertical plane where the seamless bend is located. The clearing range is limited, and the rotation of the seamless bend is driven by manually rotating the protective sleeve. After the seamless bend is rotated into place, there is no limit to the range of motion. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel multi-angle adjustment device for an air cannon includes a measuring scale, a belt conveyor located on one side of the measuring scale, a raw coal bunker located on the belt conveyor, and a compressed air cannon located on one side of the raw coal bunker. The air outlet of the compressed air cannon is equipped with a rotating bushing, and a first air supply pipe is installed on the rotating bushing. An angle adjustment mechanism is located inside the raw coal bunker and includes a fixed plate, a third air supply pipe, a fourth air supply pipe, a second drive motor, a first connecting rod, a second connecting rod, and a fixed block. The first, third, and fourth air supply pipes are connected sequentially. The third air supply pipe is a flexible hose. A fixed plate is provided at the connection between the first and third air supply pipes. A second drive motor is mounted on the fixed plate. A first connecting rod is provided at the output end of the second drive motor. The other end of the first connecting rod is hinged to the second connecting rod, and the second connecting rod is hinged to the fixed block. The fixed block is fixedly connected to the middle of the fourth air supply pipe.

[0007] In the aforementioned novel air cannon multi-angle adjustment device, the first air supply pipe is embedded in the second air supply pipe, the second air supply pipe is fixed to the side wall of the raw coal bunker, a first drive motor is provided on one side of the first air supply pipe, a drive gear is assembled at the output end of the first drive motor, a transmission gear is fitted on the outer wall of the first air supply pipe, and the drive gear meshes with the transmission gear.

[0008] The aforementioned novel air cannon multi-angle adjustment device has a protective plate around the fixed plate and a guide plate at the bottom of the protective plate, forming a closed space by the guide plate, the protective plate and the fixed plate.

[0009] The aforementioned novel air cannon multi-angle adjustment device has a guide groove on the guide plate, and elastically deformable rubber pads on both sides of the guide groove. The air outlet of the fourth air supply pipe is located between the two rubber pads and moves along the guide groove.

[0010] The aforementioned novel air cannon multi-angle adjustment device has a support frame on the inner wall of the raw coal bunker, and an arc-shaped support block at the top of the support frame, with the first air supply pipe overlapping the arc-shaped support block.

[0012] The aforementioned novel air cannon multi-angle adjustment device has a pair of anti-scattering baffles on the belt conveyor.

[0013] The beneficial effects of adopting the above technical solution are as follows:

[0014] This invention utilizes a first drive motor in conjunction with a meshing transmission gear to rotate a first gas delivery pipe on a second gas delivery pipe, adjusting the direction of the end of the gas delivery pipe so that it is vertically close to the material pile position. Then, a second drive motor drives a first connecting rod to rotate, which in turn drives a third and fourth gas delivery pipe to swing left and right, adjusting the end of the gas delivery pipe in the horizontal direction. This allows the air cannon to accurately impact the material pile position, ensuring that any sticky material in the raw coal bunker can be dispersed by the air cannon. Furthermore, the rotation position of the first gas delivery pipe can be limited by the drive gear and transmission gear. In addition, this invention also includes a protective plate and a guide plate for the angle adjustment device. The guide plate, protective plate, and fixing plate form a closed space to prevent coal dust from affecting the rotation of the second drive motor, the first rotating rod, and the second rotating rod.

[0021] like Figure 1-4As shown, this utility model includes a measuring scale body 1, a belt conveyor 2 located on one side of the measuring scale body 1, a raw coal bunker 3 located on the belt conveyor 2, and a compressed air cannon 4 located on one side of the raw coal bunker 3. The air outlet of the compressed air cannon 4 is equipped with a rotating bushing 5, and a first air supply pipe 6 is installed on the rotating bushing 5. Through the rotating bushing 5, the first air supply pipe 6 can rotate within the rotating bushing 5 and transmit compressed air. The other end of the first air supply pipe 6 is provided with an angle adjustment mechanism 7. The angle adjustment mechanism 7 is located inside the raw coal bunker 3 and includes a fixing plate 71, a third air supply pipe 72, a fourth air supply pipe 73, a second drive motor 74, a first connecting rod 75, a second connecting rod 76, and a fixing block 77. The first air supply pipe 6, the third air supply pipe 72, and the fourth air supply pipe 73 are connected in sequence. The third air supply pipe 72 is a flexible hose. A fixing plate 71 is provided at the connection between the first air supply pipe 6 and the third air supply pipe 72. The fixing plate 71 is equipped with a first air supply pipe 73. The second drive motor 74 has a first connecting rod 75 at its output end. The other end of the first connecting rod 75 is hinged to a second connecting rod 76, which is hinged to a fixed block 77. The fixed block 77 is fixedly connected to the middle of the fourth gas pipe 73. The second drive motor 74 drives the first connecting rod 75 to rotate, and then the first connecting rod 75 drives the second connecting rod 76 to move. Since the third gas pipe 72 is a flexible tube, the second connecting rod 76 will drag the third gas pipe 72 and the fourth gas pipe 73 to swing left and right during the rotation of the first connecting rod 75, thereby changing the outlet direction of the fourth gas pipe 73 and adjusting the impact direction of the gas cannon in the horizontal direction. Although the left and right swing of the third gas pipe 72 and the fourth gas pipe 73 will cause the entire gas pipeline to bend, affecting the impact force of the gas cannon, adjusting the outlet direction of the gas pipe to act more accurately on the adhesive material is more conducive to solving the problem of frequent material buildup in the raw coal bunker.

[0022] like Figure 1 , 2 As shown, the first gas supply pipe 6 is embedded in the second gas supply pipe 8, and the second gas supply pipe 8 is fixed to the side wall of the raw coal bunker 3. A first drive motor 61 is provided on one side of the first gas supply pipe 6. A drive gear 62 is assembled at the output end of the first drive motor 61. A transmission gear 63 is fitted on the outer wall of the first gas supply pipe 6. The drive gear 62 meshes with the transmission gear 63. The first drive motor 61 drives the drive gear 62 to rotate, and the drive gear 62 drives the first gas supply pipe 6 and the angle adjustment mechanism 7 to rotate through the transmission gear 63, thereby adjusting the impact direction of the air cannon in the vertical direction.

[0023] like Figure 4As shown, the fixed plate 71 is surrounded by a protective plate 78, and the bottom of the protective plate 78 is provided with a guide plate 79. The guide plate 79, the protective plate 78 and the fixed plate 71 form a closed space, which can prevent coal dust from falling into the connection between the second drive motor, the first rotating rod and the second rotating rod.

[0024] The guide plate 79 of this utility model is provided with a guide groove 791. The two sides of the guide groove 791 are respectively provided with elastically deformable rubber pads. The air outlet of the fourth air pipe 73 is located between the two rubber pads and moves along the guide groove 791, and the opening of the guide groove 791 is closed by the rubber pads.

[0025] like Figure 3 , 4 As shown, the inner wall of the raw coal bunker 3 is provided with a support frame 31, and the top of the support frame 31 is provided with an arc-shaped support block 32. The first gas transmission pipe 6 is connected to the arc-shaped support block 32.

[0026] like Figure 1 , 3 As shown, a viewing window 33 is provided on the side wall of the raw coal bunker 3. The viewing window 33 is located above the first gas transmission pipe 6. The interior of the raw coal bunker 3 can be observed through the viewing window 33, which makes it convenient for staff to identify the location of coal powder adhesion. Moreover, after removing the viewing window 33, the internal angle adjustment mechanism 7 can be inspected and repaired.

[0027] like Figure 1 As shown, the belt conveyor 2 is equipped with a pair of anti-scattering baffles 21. When the air cannon impacts the material position and the coal powder is rushed out of the raw coal bunker 3 with the air, the anti-scattering baffles 21 can block the coal powder and prevent the coal powder from rushing out of the belt conveyor 2.

[0028] Work process:

[0029] 1. The weighing scale 1 and the belt conveyor 2 form the main body of the equipment installation, which supports the overall installation of the equipment. During production, the material is put into the raw coal bunker 3 for storage and weighed and transported by the weighing scale 1 and the belt conveyor 2. When the raw coal bunker 3 is blocked by the material and the material is not discharged smoothly, the first drive motor 61 is started. The first drive motor 61 drives the drive gear 62 installed on its output end to rotate. The transmission gear 63 meshing with the drive gear 62 and the first air pipe 6 rotate, so that the angle adjustment mechanism 7 at the right end of the first air pipe 6 rotates upward, so that the pipe opening of the fourth air pipe 73 is aligned with the position of the material blockage in the vertical direction.

[0030] 2. Start the second drive motor 74. The second drive motor 74 drives the first connecting rod 75 installed at its output end to rotate. The first connecting rod 75 then drives the second connecting rod 76 to move, which in turn drives the third air supply pipe 72 and the fourth air supply pipe 73 to swing left and right, so that the opening of the fourth air supply pipe 73 faces the material blockage position. Then, the high-pressure air mass of the compressed air cannon 4 disperses the material blockage position to prevent the blockage from affecting normal production.

[0031] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
