Description

Technical Field

[0001] This utility model relates to the field of cement cyclone technology, specifically a cement cyclone equipped with a double-layer counterweight flap valve. Background Technology

[0002] Cement cyclones have significant effects in cement production. They are mainly used for material separation and collection, and achieve effective separation of dust and gas through rotating airflow, thereby improving production efficiency and thermal efficiency. The use of cement cyclones brings many benefits. First, it significantly improves production efficiency. Through cyclone preheating technology, the raw material is in a suspended state and fully contacts the hot airflow, which greatly increases the contact area between the gas and solid phases, thereby accelerating the heat transfer rate and improving thermal efficiency.

[0003] However, most cement cyclones require multiple unloaders to work together when unloading, which not only consumes more electricity but also increases the maintenance cycle of the equipment. This results in a waste of resources when unloading cement cyclones, making the unloading process inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a cement cyclone with a double-layer counterweight flap valve to solve the problem of inconvenience in unloading cement cyclones mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cement cyclone with a double-layer counterweight flap valve, comprising a cement cyclone body, an air inlet pipe, an air outlet pipe, and a collection chamber. An air inlet pipe is provided on one side of the top of the cement cyclone body, and an air outlet pipe passes through the top of the cement cyclone body. A collection chamber is provided at the end of the cement cyclone body away from the air outlet pipe. A first flap valve is provided at the bottom of the collection chamber, and a second flap valve is provided at the end of the first flap valve away from the collection chamber. A discharge port is provided at the bottom of the second flap valve, and a welded horizontal plate is provided at one end of both the first flap valve and the second flap valve.

[0006] Preferably, a flap push rod is installed at the top of the horizontal plate, and a moving rod is connected to the output end of the flap push rod.

[0007] Preferably, one end of the moving rod is rotatably connected to a flipping block via a rotating shaft, and the end of the flipping block away from the moving rod is connected to a rotating rod.

[0008] Preferably, a flap body is sleeved on the surface of the rotating rod, and a rubber protective plate is provided at the top of the flap body.

[0009] Preferably, the rubber protective plate has symmetrically distributed plug-in blocks at one end near the flap body, and the flap body has plug-in grooves at one end near the plug-in blocks.

[0010] Preferably, a reserved slot is provided inside the flip plate body on the side near the insertion slot, and a limit block is provided inside the reserved slot. The limit block is connected to the inside of the flip plate body by a reset spring.

[0011] Preferably, the insert block has a locking groove on the side near the limiting block inside.

[0012] Preferably, a fixed box is provided at the top of the air inlet pipe, and a drive motor is installed at the top of the fixed box.

[0013] Preferably, the output end of the drive motor is connected to a first rotating rod via a coupling, and a second rotating rod is provided inside the fixed box on the side near the first rotating rod via a rotating shaft.

[0014] Preferably, a gear set is fitted onto the surfaces of the second rotating rod and the first rotating rod, and a wind speed regulating plate is provided at the end of the second rotating rod away from the gear set.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This cement cyclone with a double-layer counterweight flap valve, by activating the two flap push rods, causes the flap bodies inside the first flap valve and the second flap valve to move in opposite directions, ensuring that one flap body is always closed, thereby preventing air leakage inside the cement cyclone and facilitating the unloading of the cement cyclone. By starting the drive motor, the first rotating rod connected to the output end can rotate the gear set, which in turn can rotate the wind speed regulating plate through the second rotating rod, thereby adjusting the air intake rate and improving the applicability of the cement cyclone during use.

[0016] 1. This cement cyclone separator equipped with a double-layer counterweight flap valve typically requires multiple unloaders during operation, resulting in significant resource consumption during unloading. By activating the flap pusher at the bottom, the pusher moves the connecting rod at the output end, causing the connecting rod to rotate the connected tilting block. This rotation, in turn, rotates the connected rotating rod, which in turn rotates the connected flap body, allowing material to be discharged from the collection chamber. Simultaneously, the flap pushers on the first and second flap valves operate in opposite directions, ensuring that one flap body is open while the other is closed during unloading. This maintains a closed flap body layer in the middle of the cement cyclone separator, preventing airflow from affecting material separation during discharge and making unloading more convenient.

[0017] 2. This cement cyclone separator equipped with a double-layer counterweight flap valve is designed to address the common issue that adjusting the air inlet rate is difficult during use. This makes it challenging to regulate the tangential velocity inside the cyclone and consequently, the material separation rate. By starting the drive motor, the first rotating rod connected to the output end can rotate the second rotating rod via a connected gear set. This second rotating rod, through a wind speed regulating plate, can adjust the gap inside the air inlet pipe, thereby controlling the air inlet rate. This allows for adjustment of the tangential velocity inside the cement cyclone, ultimately improving the separation effect and enhancing the overall usability of the cement cyclone separator.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-3 This utility model provides a technical solution: a cement cyclone with a double-layer counterweight flap valve, comprising a cement cyclone body 1, an air inlet pipe 2, an air outlet pipe 3, and a collection chamber 4. The air inlet pipe 2 is located on one side of the top of the cement cyclone body 1, and the air outlet pipe 3 passes through the top of the cement cyclone body 1. The collection chamber 4 is located at the end of the cement cyclone body 1 away from the air outlet pipe 3. A first flap valve 5 is located at the bottom of the collection chamber 4, and a second flap valve 6 is located at the end of the first flap valve 5 away from the collection chamber 4. A discharge port 7 is located at the bottom of the second flap valve 6. A horizontal plate 8 is welded to one end of both the first flap valve 5 and the second flap valve 6. A flap push rod 9 is installed at the top of the horizontal plate 8, and a moving rod 10 is connected to the output end of the flap push rod 9. One end of the moving rod 10 is rotatably connected to a flipping block 11 via a rotating shaft. The end of the flipping block 11 away from the moving rod 10 is connected to a rotating rod 12. A flip plate body 13 is sleeved on the surface of the rotating rod 12. A rubber protective plate 14 is provided at the top of the flip plate body 13. Symmetrically distributed insertion blocks 15 are provided at the end of the rubber protective plate 14 near the flip plate body 13. An insertion groove 16 is provided inside the flip plate body 13 near the insertion block 15. A reserved groove 17 is provided inside the flip plate body 13 near the insertion groove 16. A limit block 18 is provided inside the reserved groove 17. A return spring 19 is connected to the inside of the limit block 18 and the side of the insertion block 15 near the limit block 18. A locking groove 20 is provided inside the insertion block 15 near the limit block 18.

[0026] In practice,

[0027] See Figures 1-3 It is known that when a cement cyclone separator is in use, multiple unloaders are usually required, which consumes a lot of resources during unloading. This can be addressed by activating the flap pusher 9 at the bottom, which moves the movable rod 10 connected to the output end. The movable rod 10 then rotates the connected tilting block 11, which in turn rotates the connected rotating rod 12. This rotation of the rotating rod 12 then rotates the connected flap body 13, allowing material to be discharged from the collection chamber 4. Simultaneously, the flap pusher 9 on the side of the first flap valve 5 and the second flap valve 6 operates in opposite directions, ensuring that one flap body 13 is open and the other is closed during unloading, thus maintaining a consistent layer of material in the middle of the cement cyclone separator. The flap body 13 remains closed to prevent airflow from affecting material separation during discharge. A rubber protective plate 14 is provided on the surface of the flap body 13 to prevent material from impacting and deforming the flap body 13 during the fall. The rubber protective plate 14 can be pulled upwards, allowing it to move the insertion block 15 at the bottom. As the insertion block 15 moves, it can squeeze the limiting block 18 connected on one side, causing the limiting block 18 to separate from the locking groove 20, allowing the rubber protective plate 14 to be removed for easy replacement. This provides good protection for the flap body 13 during use. Furthermore, the use of a double-layer counterweight flap valve avoids the consumption of excessive resources by multiple unloaders, making the unloading of cement cyclone easier.

[0028] A fixed box 21 is provided at the top of the air inlet pipe 2. A drive motor 22 is installed at the top of the fixed box 21. The output end of the drive motor 22 is connected to a first rotating rod 23 through a coupling. A second rotating rod 24 is provided inside the fixed box 21 on the side close to the first rotating rod 23 and is rotatably connected by a rotating shaft. A gear set 25 is sleeved on the surface of the second rotating rod 24 and the surface of the first rotating rod 23. A wind speed regulating plate 26 is provided at the end of the second rotating rod 24 away from the gear set 25.

[0029] In practice,

[0030] See Figure 1 , Figure 2 , Figure 4 and Figure 5It is known that when a cement cyclone separator is in use, it is usually difficult to adjust the air intake rate, making it difficult to adjust the tangential velocity inside the cyclone separator and thus the separation rate of the material. This can be addressed by starting the drive motor 22, which rotates the first rotating rod 23 connected to the output end. The first rotating rod 23 rotates through the gear set 25 connected to the surface, which in turn rotates the second rotating rod 24. This second rotating rod 24 then rotates the wind speed regulating plate 26 on the surface, allowing the wind speed regulating plate 26 to adjust the gap inside the air inlet pipe 2, thereby controlling the air intake rate. This allows for adjustment of the tangential velocity inside the cement cyclone separator, thus adjusting the internal separation effect and improving the applicability of the cement cyclone separator during use.

[0031] In summary, cement cyclones have significant effects in cement production, primarily used for material separation and collection. To avoid requiring multiple unloading devices during discharge, the bottom-mounted flap pusher 9 can be activated. This allows the flap pusher 9 to move the movable rod 10 connected to the output end, causing the movable rod 10 to rotate the connected tilting block 11. The rotating block 11 then rotates the connected rotating rod 12, which in turn rotates the connected flap body. Rotation of valve 13 allows for the discharge of materials from the collection chamber 4. Simultaneously, the flap push rod 9, located on one side of the first flap valve 5 and the second flap valve 6, operates in opposite directions, ensuring that one flap body 13 is open and the other is closed during unloading. This ensures that there is always one layer of flap bodies 13 closed in the middle of the cement cyclone, preventing airflow from affecting material separation during discharge. This makes unloading the cement cyclone more convenient. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
