Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and in particular relates to an air blast device and active bauxite calcining equipment. Background Art

[0002] In the production process of water purification materials, the raw materials need to be calcined. For example, calcium aluminate powder is made from high-grade bauxite and limestone through crushing, drying, ball milling, blanking, calcining, and grinding. During the calcining process, a blast device is required to continuously blow air into the calcining furnace. In the prior art, air is blown into the calcining furnace by a blower, but the air outlet pipe of the general blower is fixedly connected to the air inlet pipe of the calcining furnace, and the blower cannot be moved. It is also inconvenient to disassemble the air inlet pipe and the air outlet pipe, which is not only not conducive to maintenance, but also can only be used exclusively for the calcining furnace. When the calcining furnace is out of use, the blower is no longer used, which reduces the utilization rate of the equipment. Therefore, a blast device and an activated bauxite calcining equipment are needed to solve the above technical problems. Utility Model Content

[0003] To solve the above defects in the prior art, the utility model provides a blowing device, including a blower, which is fixed on a trolley for easy movement and used for blowing air in different equipments. Brakes are provided on the running wheels of the trolley to keep the blower stable and not moving when in use. A push handle is fixed on the trolley.

[0004] The air outlet of the blower is connected to an air outlet pipe, and a fixing component is provided on the air outlet pipe.

[0005] The fixing component includes an upper clamp and a lower clamp that cooperate with each other. Both the upper clamp and the lower clamp are arc-shaped and are adapted to the air outlet pipe. Connecting blocks are fixedly connected to both ends of the upper clamp and the lower clamp. An adjusting member is provided between the connecting blocks of the upper clamp and the lower clamp on the same side. The adjusting member includes a bidirectional screw rod. The forward threaded section and the reverse threaded section of the bidirectional screw rod are respectively in threaded cooperation with the connecting blocks of the corresponding upper clamp and lower clamp. A first bevel gear is fixed at the center of the bidirectional screw rod. The first bevel gear meshes with a second bevel gear. A rotating handle is connected to the center of the second bevel gear. The rotating handle is connected to the bidirectional screw rod through a U-shaped member. The bidirectional screw rod is respectively rotatably connected to the two horizontal parts of the U-shaped member through bearings. The rotating handle is rotatably connected to the vertical part of the U-shaped member through a bearing. The setting of the fixing component facilitates the connection and disassembly of the air outlet pipe and the air inlet pipe of the equipment, and the operation is simple and efficient. Specifically, when the air inlet pipe and the air outlet pipe are connected, the upper clamp and the lower clamp are in a relaxed state, which is convenient for sleeving the air inlet end of the air inlet pipe on the air outlet pipe. Subsequently, by rotating the rotating handles on both sides of the upper clamp and the lower clamp, the corresponding second bevel gears are driven to rotate. The second bevel gear drives the first bevel gear meshing with it to rotate. The first bevel gear drives the corresponding bidirectional screw rod to rotate. As the bidirectional screw rod rotates, the connecting blocks on its forward threaded section and reverse threaded section move towards each other, and the upper clamp and the lower clamp cooperate with each other to continuously clamp the air inlet pipe on the air outlet pipe to prevent air leakage and the detachment of the air inlet pipe. When it is necessary to remove the air inlet pipe, the two rotating handles are rotated in the reverse direction, and the two bidirectional screw rods rotate in the reverse direction. The connecting blocks on their forward threaded section and reverse threaded section move away from each other, and the upper clamp and the lower clamp release the limit fixation of the air inlet pipe, which is convenient for removing the air inlet pipe.

[0006] Preferably, an elastic connecting piece is connected between one ends of the upper clamp and the lower clamp on the same side. The setting of the elastic connecting piece can fix the air inlet pipe where the upper clamp and the lower clamp cannot contact each other, improve the sealing performance again, and avoid air leakage.

[0007] Preferably, sliding grooves are provided on the upper clamp and the lower clamp corresponding to both ends of the elastic connecting piece. Both ends of the elastic connecting piece are respectively located in the corresponding sliding grooves and are connected to the sliding grooves through compression springs. This setting improves the stability and reliability of the elastic connecting piece when the upper clamp and the lower clamp move.

[0008] The utility model further includes an active bauxite calcination device, which includes a blast device as described above.

[0009] Preferably, it further includes a calcination furnace, and the air inlet pipe of the calcination furnace is connected to the air outlet pipe of the blower.

[0010] The present utility model further includes other components that can enable a blast device and an activated bauxite calcination device to be used normally, such as the control components of the blower, etc., which are all conventional technical means in the art. In addition, the devices or components not defined in the present utility model, such as the bidirectional screw, the calcination furnace, the compression spring, the elastic connecting piece, the brake, etc., all adopt the conventional technical means in the art and conventional equipment in the art.

[0011] The beneficial effects of the present utility model are as follows: The structure is reasonable, which is convenient for the efficient disassembly and connection of the air inlet pipe and the air outlet pipe of the blower, and the connection between the air inlet pipe and the air outlet pipe is reliable; The blower is movable and can be applied to different devices that require air blowing, improving the utilization rate of the blower.

[0017] Embodiment 1

[0018] As Figure 1-2 shown, the present utility model provides a blast device, including a blower 1, the blower 1 is fixed on a trolley 2, which is convenient for movement and used for blowing air for different devices. A brake is provided on the traveling wheels of the trolley 2, which can keep the blower 1 stable and immovable when in use. A pusher 3 is fixed on the trolley 2;

[0019] The air outlet of the blower 1 is connected with an air outlet pipe 4, and a fixing component is provided on the air outlet pipe 4,

[0020] The fixing component includes an upper clamp 5 and a lower clamp 6 which cooperate with each other. Both the upper clamp 5 and the lower clamp 6 are arc-shaped and are adapted to the air outlet pipe 4. Connecting blocks 10 are fixedly connected to both ends of the upper clamp 5 and the lower clamp 6. An adjusting member is provided between the connecting blocks 10 of the upper clamp 5 and the lower clamp 6 on the same side. The adjusting member includes a bidirectional screw 11. The forward threaded section and the reverse threaded section of the bidirectional screw 11 are respectively in threaded cooperation with the connecting blocks 10 of the corresponding upper clamp 5 and lower clamp 6. A first bevel gear 12 is fixed at the center of the bidirectional screw 11. The first bevel gear 12 meshes with a second bevel gear 13. A rotating handle 7 is connected to the center of the second bevel gear 13. The rotating handle 7 is connected to the bidirectional screw 11 through a U-shaped member 14. The bidirectional screw 11 is respectively rotatably connected to the two horizontal parts of the U-shaped member 14 through bearings. The rotating handle 7 is rotatably connected to the vertical part of the U-shaped member 14 through a bearing. The setting of the fixing component facilitates the connection and disconnection of the air outlet pipe 4 and the air inlet pipe 8 of the equipment, and the operation is simple and efficient.

[0021] An elastic connecting piece 9 is connected between one ends of the upper clamp 5 and the lower clamp 6 on the same side. The elastic connecting piece can be a rubber sheet, a silica gel sheet, etc. The setting of the elastic connecting piece 9 can fix the air inlet pipe 8 where the upper clamp 5 and the lower clamp 6 cannot contact, improve the sealing performance again, and avoid air leakage.

[0022] Chutes for cooperation are provided on the upper clamp 5 and the lower clamp 6 corresponding to both ends of the elastic connecting piece 9. Both ends of the elastic connecting piece 9 are respectively located in the corresponding chutes and are connected to the chutes through compression springs 15. This setting increases the moving range between the upper clamp 5 and the lower clamp 6, and at the same time improves the stability and reliability of the elastic connecting piece 9 when the upper clamp 5 and the lower clamp 6 move loosely.

[0023] When in use, push the blower to the equipment (calcining furnace), brake the trolley to ensure that the blower does not move during operation, and then connect the air inlet pipe 8 of the equipment with the air outlet pipe 4 of the blower. When connected, the upper clamp 5 and the lower clamp 6 are in a relaxed state, which is convenient for putting the air inlet end of the air inlet pipe 8 on the air outlet pipe 4, and then rotate the rotating handles 7 on both sides of the upper clamp 5 and the lower clamp 6 to drive the corresponding bevel gear 2 13 to rotate, and the bevel gear 2 13 drives the bevel gear 1 12 meshing with it to rotate, and the bevel gear 12 drives the corresponding two-way screw The rod 11 rotates, and with the rotation of the two-way screw 11, the connecting blocks 10 on the forward threaded section and the reverse threaded section move toward each other, and the upper clamp 5 and the lower clamp 6 cooperate with each other to continuously clamp the air inlet pipe 8 on the air outlet pipe 4 to prevent air leakage and the air inlet pipe 8 from falling off. When the air inlet pipe 8 needs to be removed, the two rotating handles 7 are rotated in the opposite direction, and the two two-way screws 11 rotate in the opposite direction, and the connecting blocks 10 on the forward threaded section and the reverse threaded section move backwards, and the upper clamp 5 and the lower clamp 6 release the limit fixation on the air inlet pipe 8, which facilitates the removal of the air inlet pipe 8.
