[0003] The cyclone is an important equipment in the cement production process in the prior art, which mainly separates and recovers dust and fine powder in flue gas, effectively controls flue gas emission, and achieves the goals of environmental protection and energy saving and consumption reduction. The working principle of the cyclone is based on the principle that dust particles settle under the action of centrifugal force. The size of the traditional cyclone inlet is small. When the wind enters the cyclone inlet, the wind speed is fast, which results in large airflow resistance in the cyclone inlet and more heat energy loss in the airflow, thereby affecting the operating efficiency of the cyclone. UTILITY MODEL CONTENT

[0004] The utility model discloses a cyclone resistance reduction structure for cement production, which solves the problem of large cyclone inlet resistance in the market.

[0005] To achieve the above object, the utility model provides the following technical scheme: a cyclone resistance reduction structure for cement production, comprising: a cyclone main body, an air inlet connecting pipe, an air outlet pipe and a discharge pipe, the top outer side of the cyclone main body is connected with the air inlet connecting pipe, the top of the cyclone main body is connected with the air outlet pipe, the bottom of the cyclone main body is connected with the discharge pipe, a connecting frame is arranged on one side of the air inlet connecting pipe close to the cyclone main body, a through hole is formed in one side of the air inlet connecting pipe close to the connecting frame, first U-shaped blocks are welded on the top and the bottom of the air inlet connecting pipe, a threaded knob is threadedly connected in the first U-shaped block, and second U-shaped blocks are welded on the top and the bottom of the connecting frame.

[0006] Preferably, a connecting shaft is welded in the second U-shaped block, and a connecting block is rotatably connected to the outer side of the connecting shaft.

[0007] Preferably, a threaded groove matching the size of the threaded knob is formed in the connecting block.

[0008] Preferably, a sliding structure is formed between the connecting block and the first U-shaped block.

[0009] Preferably, the top and bottom of the connecting frame are flush with the top and bottom of the air inlet connecting pipe.

[0010] Preferably, a connection box is connected to the outside of the exhaust pipe, and a cylinder body is installed on the outside of the connection box.

[0011] Preferably, a telescopic rod is connected to the interior of the cylinder body, and a stopper is connected to the end of the telescopic rod.

[0012] Preferably, the bottom of the stopper is connected to a limiting block, and a connecting column is installed inside the stopper.

[0013] Preferably, the outer side of the connecting column is rotatably connected to a gear, and a gear block is installed inside the connecting box close to the gear.

[0014] Preferably, a meshing structure is formed between the gear and the gear block, and a rotating structure is formed between the gear and the connecting column.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the cyclone resistance reduction structure for cement production can push the connecting frame toward the through hole, and when the connecting frame moves to the outside of the air inlet connecting pipe, the interior of the connecting frame and the air inlet connecting pipe can be interconnected through the through hole. When the connecting block moves, it can be rotated through the connecting shaft. When one end of the block moves to a specified position inside the exhaust pipe, the airflow near the block changes direction and reduces speed. The wind speed inside the exhaust pipe can be appropriately reduced through the block, so that the subsequent hot air can be in contact with the material for a longer time, and the material can be better dried.

[0016] 1. A cyclone is a crucial piece of equipment in the cement production process. Its efficient separation, simple structure, high-temperature and high-pressure resistance, and environmental protection and energy-saving characteristics make it an indispensable component of cement production. The airflow resistance inside the air inlet connecting pipe of a conventional cyclone is relatively high, which can affect the operating efficiency of the cyclone body. The connecting frame can be pushed toward the through hole. When the connecting frame moves to the outside of the air inlet connecting pipe, the through hole allows the connecting frame and the interior of the air inlet connecting pipe to communicate with each other. The connecting block can be rotated via the connecting shaft as it moves. When the connecting block rotates and moves to the inside of the first U-shaped block, the end of the threaded knob can be inserted into the first U-shaped block and tightened. When the threaded knob is tightened, its end can thread through the connecting block, thereby securing the connecting block. The connecting frame can now be installed outside the air inlet connecting pipe. When hot air enters the air inlet connecting pipe, the connecting frame increases the inlet cross-sectional area of ​​the air inlet connecting pipe, reducing the inlet air velocity and the momentum loss of the gas medium as it flows through the cyclone. This reduces resistance and thus improves the operating efficiency of the cyclone body.

[0017] 2. The cyclone plays an important role in the cement production process. When the hot air enters the main body of the cyclone through the air inlet connecting pipe, it will be discharged from the top of the exhaust pipe. Since the exhaust speed of the exhaust pipe is relatively fixed, it is difficult to reduce the exhaust speed of the exhaust pipe according to actual production conditions. When the cylinder main body is running, it can drive the telescopic rod to move in the direction close to the exhaust pipe. When the telescopic rod moves, it can drive the block to move. When the block moves, it can drive the limit block to move, and at the same time the block moves, it can drive the connecting column and the gear to move. When the gear moves, it can engage and move on the gear block, and when the gear moves, it can rotate through the connecting column. When one end of the block moves to the specified position inside the exhaust pipe, the airflow near the block changes direction and reduces speed. The block can appropriately reduce the wind speed inside the exhaust pipe, so that the subsequent hot air can be in contact with the material for a longer time, and the material can be better dried.

[0026] When the utility model is implemented, the cyclone is one of important equipment in the cement production process, its efficient separation, simple structure, high temperature and high pressure resistance and environmental protection energy saving etc. characteristics make it become an indispensable part in the cement production, the air resistance in the inside of air inlet connecting pipe 2 on the traditional cyclone is big, can influence the operation efficiency of cyclone main part 1, can push the direction of connecting frame 5 to the direction of through -hole 6, when connecting frame 5 moves to the outside of air inlet connecting pipe 2, through through -hole 6 can make the inside of connecting frame 5 and air inlet connecting pipe 2 intercommunicate, and first U -shaped block 7 and second U -shaped block 9 can be close to each other, at this moment, two groups of connecting block 11 can be pulled to the direction of air inlet connecting pipe 2 respectively, when connecting block 11 moves, can rotate through connecting shaft 10, when connecting block 11 rotates and moves to the inside of first U -shaped block 7, can insert the end of screw knob 8 into first U -shaped block 7 and tighten, when screw knob 8 is tightened, the end thereof can be screwed and penetrates connecting block 11, so as to fix connecting block 11, at this moment, connecting frame 5 can be installed on the outside of air inlet connecting pipe 2.

[0027] Refer to Figure 1-Figure 3 When hot air enters the inside of air inlet connecting pipe 2, the inlet cross -sectional area of air inlet connecting pipe 2 can be increased through connecting frame 5, the inlet air speed can be reduced, the momentum loss formed when gas medium flows through the cyclone can be reduced, and the purpose of reducing resistance is achieved, so that the operation efficiency of cyclone main part 1 can be improved.

[0028] Refer to Figure 1 , Figure 4 And Figure 5It can be seen that the outside of the exhaust duct 3 is connected to the connecting box 12, the outside of the connecting box 12 is installed with a cylinder body 13, the inside of the cylinder body 13 is connected with a telescopic rod 14, the end of the telescopic rod 14 is connected with a stopper 15, the bottom of the stopper 15 is connected with a limit block 16, the inside of the stopper 15 is installed with a connecting column 17, the outside of the connecting column 17 is rotatably connected with a gear 18, and the inside of the connecting box 12 near the gear 18 is installed with a gear block 19, a meshing structure is formed between the gear 18 and the gear block 19, a rotating structure is formed between the gear 18 and the connecting column 17, and a sliding structure is formed between the limit block 16 and the connecting box 12.

[0029] In specific implementation, the cyclone plays an important role in the cement production process. When the hot air enters the cyclone main body 1 through the air inlet connecting pipe 2, it will be discharged from the top of the exhaust pipe 3. Since the exhaust speed of the exhaust pipe 3 is relatively fixed, it is difficult to reduce the exhaust speed of the exhaust pipe 3 according to the actual production situation.

When the gear 18 moves, it can be rotated through the connecting column 17. When one end of the stopper 15 moves to the specified position inside the exhaust duct 3, the airflow near the stopper 15 changes direction and reduces speed.

[0030] See Figure 1 、 Figure 4 and Figure 5 It can be seen that the wind speed inside the exhaust pipe 3 can be appropriately reduced by the block 15, so that the subsequent hot air can be in contact with the material for a longer time, and the material can be dried better.

[0031] In summary, when the resistance reduction structure of the cyclone barrel for cement production is used, the connecting frame 5 can be pushed towards the direction close to the through hole 6, when the connecting frame 5 moves to the outside of the air inlet connecting pipe 2, the inside of the connecting frame 5 and the air inlet connecting pipe 2 can be communicated through the through hole 6, meanwhile, the first U-shaped block 7 and the second U-shaped block 9 can be close to each other, the inlet cross-sectional area of the air inlet connecting pipe 2 can be increased through the connecting frame 5, the inlet air speed can be reduced, the momentum loss of the gas medium when flowing through the cyclone barrel can be reduced, and the purpose of resistance reduction can be achieved, so that the operation efficiency of the cyclone barrel body 1 can be improved, when one end of the stop block 15 moves to the specified position inside the air outlet pipe 3, the air flow near the stop block 15 changes direction and speed, the air speed inside the air outlet pipe 3 can be appropriately reduced through the stop block 15, so that the subsequent hot air can contact the material for a longer time, and the material can be better dried, and the contents not described in detail in the description belong to the prior art known to those skilled in the art.
