Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a drying equipment for calcium hydroxide desulfurizing agent. Background Technology

[0002] Calcium hydroxide desulfurizer is an alkaline desulfurizer with calcium hydroxide, commonly known as slaked lime or quicklime, as its core component. It is mainly used for the removal of sulfur dioxide from industrial flue gas. It typically appears as a white powder or granules. Granular calcium hydroxide desulfurizer needs to be dried and packaged after production. Current methods for drying granular calcium hydroxide desulfurizer involve placing it on a conveyor belt, which then transports it to a drying device, where it is dried.

[0003] As disclosed in CN220288096U, a drying device for calcium-based desulfurizing agents includes a drying box with an inlet and an outlet at the top and bottom, respectively, and a hot air blower that conveys hot air into the drying box. Multiple transverse conveyor belts are arrayed on two opposite side walls inside the drying box, and the conveyor belts on both sides are staggered to form an S-shaped conveying channel inside the drying box that transports material from the inlet to the outlet. A material inlet is provided on the side wall between two adjacent conveyor belts on the same side at the bottom of the drying box. A support platform that moves up and down with the height of the drying box is provided on one side of the drying box. A material inlet conveyor that slides towards the material inlet is provided on the support platform. The material inlet conveyor can move through the material inlet into the S-shaped conveying channel and move the material passing through the S-shaped conveying channel out of the drying box.

[0004] It achieves high drying efficiency and good drying effect without taking up too much floor space.

[0005] However, this does not solve the problem that existing drying equipment of this type is generally not conducive to convenient, continuous batch drying operations, and is not convenient for the drying equipment to move back and forth to dry calcium hydroxide desulfurizer. Local temperature differences in calcium hydroxide desulfurizer can easily affect the drying effect, thus affecting the quality and efficiency of drying calcium hydroxide desulfurizer.

A filter cylinder is installed at the top of the hot air fan, with one end extending into the interior of the hot air fan. A filter screen is installed inside the filter cylinder. A downdraft duct is installed on the outer wall of the filter cartridge, with one end extending into the interior of the filter cartridge and the other end extending into the interior of the drying hood. A servo motor is installed at the bottom of the support frame, and a pulley assembly is provided at the output end of the servo motor. A rotating shaft is movably installed inside the support frame on one side of the servo motor, and the rotating shaft extends to the outside of the support frame. The pulley assembly extends to the surface of the rotating shaft. A drive pulley is symmetrically installed on the end of the rotating shaft away from the pulley assembly. A movable belt is fitted on the surface of each drive pulley. A support shaft is movably installed inside the support frame on the side away from the rotating shaft, and the support shaft extends to the outside of the support frame.

[0008] Preferably, the surface of the support shaft is symmetrically fitted with support pulleys, and the movable belt extends to the surface of the support pulleys, with multiple sets of conveying rods at equal intervals installed between the two sides of the movable belt.

[0009] Preferably, multiple sets of storage hoods with equal spacing are provided on the outside of the support frame below the feeding hood, and the storage hoods are slidably connected to the conveying rod, and iron blocks are installed on the outer wall of each storage hood.

[0010] Preferably, door panels are symmetrically and movably installed on the outer wall of the feed hood, and first connecting seats are symmetrically installed on the outer wall of the door panels. Drive shafts are symmetrically and movably installed on the outer wall of the feed hood on one side of the first connecting seat, and the drive shafts are connected to the first connecting seats.

[0011] Preferably, the surface of the drive shaft is fitted with a torsion spring, one end of the torsion spring is connected to the feed hood, and the other end of the torsion spring is connected to the door panel.

[0012] Preferably, a fixing plate is installed on the outer wall of the support frame on one side of the feed hood, a stepper motor is installed at the bottom end of the fixing plate, a power shaft is installed at the output end of the stepper motor, and the power shaft extends to the outside of the fixing plate.

[0013] Preferably, a first rocker arm is fitted onto the surface of the power shaft, a connecting pin is installed inside the first rocker arm on the side away from the power shaft, and the connecting pin extends to the outside of the first rocker arm. A connecting rocker arm is fitted onto the surface of the connecting pin, a linkage shaft is installed inside the connecting rocker arm on the side away from the connecting pin, and the linkage shaft extends to the outside of the connecting rocker arm.

[0014] Preferably, a second rocker arm is fitted onto the surface of the linkage shaft, a second connecting seat is installed at the top of the fixing plate near the second rocker arm, the second rocker arm extends to the outside of the second connecting seat, and the second connecting seat is slidably connected to the second rocker arm. An electromagnet is installed at the end of the second rocker arm away from the linkage shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the drying equipment not only realizes the convenient batch continuous drying operation of calcium hydroxide desulfurizing agent in a production line, reducing the loss of hot air, but also facilitates the convenient reciprocating movement of the drying equipment to dry the calcium hydroxide desulfurizing agent, avoiding the local temperature difference of the calcium hydroxide desulfurizing agent from affecting the drying effect, and improving the quality and efficiency of drying the calcium hydroxide desulfurizing agent.

[0016] A servo motor drives a pulley assembly to rotate, which in turn drives a rotating shaft. This shaft in turn drives a drive pulley, which in turn drives a moving belt. The moving belt, supported by a support shaft, drives a support pulley, which in turn drives a conveyor rod. The conveyor rod then moves multiple storage hoods. The storage hoods pass through a feeding hood into the drying hood. Air is filtered through a filter screen and enters a filter cylinder. From there, the air enters a hot air blower. Heated and transported by the hot air blower, the hot air is then delivered through an upper duct into the drying hood to facilitate the drying of the calcium hydroxide desulfurizing agent inside the storage hoods. In the blower drying process, when the hot air blower is running, external gas and gas from inside the lower duct simultaneously enter the filter cartridge. The lower duct draws out the gas from the bottom of the drying hood under negative pressure, facilitating the reuse of the residual heat gas at the bottom of the drying hood. Once the calcium hydroxide desulfurizer inside the storage hood is dried, it is discharged by the conveyor rod, facilitating a continuous batch drying operation for the calcium hydroxide desulfurizer. This process enables convenient and continuous batch drying of the calcium hydroxide desulfurizer, facilitating the rapid and convenient transport of the calcium hydroxide desulfurizer and improving the efficiency of batch drying.

[0017] As the material passes through the storage hood and the feeding hood, the door panel is automatically opened under the action of gravity and the conveyor rod. After the storage hood enters the interior of the feeding hood, the torsion spring supports the door panel and the first connecting seat, and the torsion spring drives the door panel and the first connecting seat to rotate around the drive shaft. This facilitates the automatic closing and resetting of the door panel, and helps the feeding hood form a relatively sealed space, reducing the loss of hot air. This achieves automatic opening and closing of the door when the drying equipment is conveying calcium hydroxide desulfurizing agent for drying, reducing the loss of hot air and lowering energy consumption.

[0018] When the electromagnet is activated, the iron block connects to it. The stepper motor drives the power shaft to rotate, which in turn drives the first rocker arm to rotate. The first rocker arm, via a connecting pin, drives a linked rocker arm to reciprocate. This linked rocker arm, via a linkage shaft, drives the second rocker arm to reciprocate under the movable support of the second connecting seat. The second rocker arm drives the electromagnet to reciprocate, which in turn drives the storage hood to reciprocate. This facilitates the reciprocating movement of the storage hood and the calcium hydroxide desulfurizer inside, ensuring sufficient contact between the calcium hydroxide desulfurizer and the hot airflow. This prevents localized temperature differences in the calcium hydroxide desulfurizer from affecting the drying effect. After drying is complete, the stepper motor stops rotating, the electromagnet is de-energized, and the electromagnet disconnects from the iron block. The servo motor then resumes the movement of the storage hood. This process enables convenient reciprocating drying of the calcium hydroxide desulfurizer, ensuring sufficient contact between the calcium hydroxide desulfurizer and the hot airflow, preventing localized temperature differences from affecting the drying effect, and improving the quality and efficiency of the calcium hydroxide desulfurizer drying process.

[0029] Please see Figure 1-8This utility model provides an embodiment of a drying device for calcium hydroxide desulfurizing agent, comprising a support frame 1 and a drying hood 4. The drying hood 4 is installed at the top of the support frame 1. Feed hoods 3 are symmetrically installed at the top of the support frame 1 on one side of the drying hood 4. A connecting frame 5 is installed on the outer wall of the support frame 1 on one side of the drying hood 4. A hot air blower 6 is installed at the top of the connecting frame 5. An upper air duct 7 is installed on the outer wall of the hot air blower 6, with one end extending into the interior of the hot air blower 6 and the other end extending into the interior of the drying hood 4. A filter cylinder 8 is installed at the top of the hot air blower 6, with one end extending into the interior of the hot air blower 6. A filter screen 9 is installed inside the filter cylinder 8. A lower air duct 10 is installed on the outer wall of the filter cylinder 8, with one end extending into the interior of the filter cylinder 8 and the other end extending into the interior of the drying hood 4. A servo motor 11 is installed at the bottom of the support frame 1. The output end of 1 is provided with a pulley assembly 15. A rotating shaft 16 is movably installed inside the support frame 1 on one side of the servo motor 11, and the rotating shaft 16 extends to the outside of the support frame 1. The pulley assembly 15 extends to the surface of the rotating shaft 16. A drive pulley 17 is symmetrically installed on the end of the rotating shaft 16 away from the pulley assembly 15. A movable belt 33 is fitted on the surface of each drive pulley 17. A support shaft 14 is movably installed inside the support frame 1 on the side away from the rotating shaft 16, and the support shaft 14 extends to the outside of the support frame 1. A support pulley 13 is symmetrically fitted on the surface of the support shaft 14, and the movable belt 33 extends to the surface of the support pulley 13. Multiple sets of conveying rods 18 with equal spacing are installed between the two sides of the movable belt 33. Multiple sets of storage hoods 23 with equal spacing are provided outside the support frame 1 below the feed hood 3. The storage hoods 23 are slidably connected to the conveying rods 18. Iron blocks 24 are installed on the outer wall of each storage hood 23.

[0030] The calcium hydroxide desulfurizing agent is placed inside the storage hood 23. Multiple sets of storage hoods 23 are placed on the surface of the conveyor rod 18. The servo motor 11 is turned on. Supported by the support frame 1, the servo motor 11 drives the pulley assembly 15 to rotate. The pulley assembly 15 drives the rotating shaft 16 to rotate. The rotating shaft 16 drives the drive pulley 17 to rotate. The drive pulley 17 drives the moving belt 33 to move. Supported by the support shaft 14, the moving belt 33 drives the support pulley 13 to rotate. Supported by the support pulley 13, the moving belt 33 drives the conveyor rod 18 to move. The conveyor rod 18 drives multiple sets of storage hoods 23 to move. The storage hoods 23 pass through the feed hood 3 and enter the interior of the drying hood 4. The hot air fan 6 is turned on. Supported by the connecting frame 5, the air enters the interior of the filter cylinder 8 after being filtered by the filter screen 9. The air then enters the interior of the hot air fan 6 through the filter cylinder 8. Under the heating and conveying of the hot air blower 6, hot air is conveyed through the upper air pipe 7 to the inside of the drying hood 4 to facilitate the blowing and drying of the calcium hydroxide desulfurizer inside the storage hood 23. When the hot air blower 6 is running, the external gas and the gas inside the lower air pipe 10 enter the inside of the filter cylinder 8 at the same time. The lower air pipe 10 draws out the gas at the bottom of the drying hood 4 under negative pressure. The lower air pipe 10 facilitates the reuse of the residual heat gas at the bottom of the drying hood 4. After the calcium hydroxide desulfurizer inside the storage hood 23 is dried, it is discharged by the conveyor rod 18 to facilitate the continuous batch drying operation of the calcium hydroxide desulfurizer. This realizes the convenient continuous batch drying operation of the calcium hydroxide desulfurizer by the drying equipment, facilitates the convenient and rapid conveying of the calcium hydroxide desulfurizer, and improves the efficiency of batch drying of calcium hydroxide desulfurizer.

[0031] A door panel 19 is symmetrically and movably installed on the outer wall of the feed hood 3. A first connecting seat 20 is symmetrically installed on the outer wall of the door panel 19. A drive shaft 21 is symmetrically and movably installed on the outer wall of the feed hood 3 on one side of the first connecting seat 20. The drive shaft 21 is connected to the first connecting seat 20. A torsion spring 22 is fitted on the surface of the drive shaft 21. One end of the torsion spring 22 is connected to the feed hood 3, and the other end of the torsion spring 22 is connected to the door panel 19.

[0032] When the storage hood 23 passes through the feeding hood 3, under the action of gravity and the conveying of the storage hood 23 by the conveying rod 18, the door panel 19 is automatically pushed open. After the storage hood 23 enters the interior of the feeding hood 3, under the elastic support of the torsion spring 22 and the movable support of the transmission shaft 21 on the first connecting seat 20, the torsion spring 22 drives the door panel 19 and the first connecting seat 20 to rotate around the transmission shaft 21, so as to facilitate the automatic closing and reset of the door panel 19, and to facilitate the formation of a relatively sealed space in the feeding hood 3, thereby reducing the loss of hot air. This realizes the automatic opening and closing of the door when the drying equipment is conveying calcium hydroxide desulfurizing agent for drying, reducing the loss of hot air and reducing energy consumption.

[0033] A fixing plate 12 is installed on the outer wall of the support frame 1 on one side of the feed hood 3. A stepper motor 25 is installed at the bottom of the fixing plate 12. A power shaft 26 is installed at the output end of the stepper motor 25 and extends to the outside of the fixing plate 12. A first rocker arm 27 is fitted on the surface of the power shaft 26. A connecting pin 28 is installed inside the first rocker arm 27 on the side away from the power shaft 26 and extends to the outside of the first rocker arm 27. A connecting rocker arm 29 is fitted on the surface of the connecting pin 28. A linkage shaft 30 is installed inside the linkage rocker arm 29 on the side away from the connecting pin 28 and extends to the outside of the linkage rocker arm 29. A second rocker arm 31 is fitted on the surface of the linkage shaft 30. A second connecting seat 32 is installed at the top of the fixing plate 12 near the second rocker arm 31 and the second rocker arm 31 extends to the outside of the second connecting seat 32. The second connecting seat 32 is slidably connected to the second rocker arm 31. An electromagnet 2 is installed at the end of the second rocker arm 31 away from the linkage shaft 30.

[0034] When the storage hood 23 moves to one side of the fixed plate 12, the servo motor 11 is turned off, causing the conveyor rod 18 to stop conveying the storage hood 23. When the iron block 24 approaches the electromagnet 2, the electromagnet 2 is turned on. Under the magnetic connection between the electromagnet 2 and the iron block 24, the iron block 24 is connected to the electromagnet 2. The stepper motor 25 is turned on. Under the support of the fixed plate 12, the stepper motor 25 drives the power shaft 26 to rotate. The power shaft 26 drives the first rocker arm 27 to rotate. The first rocker arm 27 drives the linked rocker arm 29 to reciprocate through the connecting pin 28. The linked rocker arm 29 drives the second rocker arm 31 to reciprocate under the movable support of the second connecting seat 32 through the linkage shaft 30. The second rocker arm 31 drives the electromagnet 2 to reciprocate. The electromagnet 2 drives the storage hood 24 through the iron block 24. The reciprocating motion of the storage hood 23 facilitates the reciprocating movement of the calcium hydroxide desulfurizing agent, allowing it to disperse within the hood and ensure sufficient contact with the hot airflow. This prevents localized temperature differences within the desulfurizing agent from affecting the drying effect. After drying is complete, the stepper motor 25 stops rotating, the electromagnet 2 is de-energized, and the electromagnet 2 disconnects from the iron block 24. The servo motor 11 then continues to move the storage hood 23, enabling convenient reciprocating drying of the calcium hydroxide desulfurizing agent. This ensures sufficient contact between the desulfurizing agent and the hot airflow, preventing localized temperature differences and improving the drying quality and efficiency of the desulfurizing agent.

[0035] In this embodiment, the following steps are taken: First, calcium hydroxide desulfurizing agent is placed inside the storage hood 23. Multiple storage hoods 23 are then placed on the surface of the conveyor rod 18. The servo motor 11 drives the pulley assembly 15 to rotate, which in turn drives the rotating shaft 16 to rotate. The rotating shaft 16 drives the drive pulley 17 to rotate, which in turn drives the moving belt 33 to move. The moving belt 33, supported by the support shaft 14, drives the support pulley 13 to rotate, which in turn drives the conveyor rod 18 to move. The conveyor rod 18 then drives the multiple storage hoods 23 to move. The storage hoods 23 pass through the feed hood 3 and enter the drying hood 4. Air is filtered by the filter screen 9 and enters the filter cylinder 8. Through the filter cylinder 8, the air enters the hot air. Inside the machine 6, heated and conveyed by the hot air blower 6, hot air is transported through the upper air duct 7 to the inside of the drying hood 4 to facilitate the blowing and drying of the calcium hydroxide desulfurizing agent inside the storage hood 23. When the hot air blower 6 is running, external gas and gas from the lower air duct 10 simultaneously enter the filter cartridge 8. The lower air duct 10 draws out the gas at the bottom of the drying hood 4 under negative pressure, facilitating the reuse of the residual heat gas at the bottom of the drying hood 4. After the calcium hydroxide desulfurizing agent inside the storage hood 23 is dried, it is discharged by the conveyor rod 18 to facilitate continuous batch drying of the calcium hydroxide desulfurizing agent. When the storage hood 23 passes through the feed hood 3, under the action of gravity and conveyed by the conveyor rod 18, the storage hood 23 is... The door panel 19 is automatically opened. After the storage hood 23 enters the interior of the feeding hood 3, under the elastic support of the torsion spring 22 and the movable support of the transmission shaft 21 on the first connecting seat 20, the torsion spring 22 drives the door panel 19 and the first connecting seat 20 to rotate around the transmission shaft 21. This facilitates the automatic closing and resetting of the door panel 19, and facilitates the formation of a relatively sealed space in the feeding hood 3, reducing the loss of hot air. This achieves automatic opening and closing of the door when the drying equipment is conveying calcium hydroxide desulfurizing agent for drying, reducing the loss of hot air and lowering energy consumption. When the storage hood 23 moves to one side of the fixed plate 12, the servo motor 11 is turned off, causing the conveying rod 18 to stop conveying the storage hood 23. When the iron block 24 approaches the electromagnet 2, the electromagnet 2 is turned on. With the magnetic connection between iron block 2 and iron block 24, iron block 24 is connected to electromagnet 2. Stepper motor 25 is activated, and supported by fixed plate 12, it drives power shaft 26 to rotate. Power shaft 26 drives first rocker arm 27 to rotate. First rocker arm 27, via connecting pin 28, drives linked rocker arm 29 to reciprocate. Linked rocker arm 29, via linkage shaft 30, drives second rocker arm 31 to reciprocate under the movable support of second connecting seat 32. Second rocker arm 31 drives electromagnet 2 to reciprocate. Electromagnet 2, via iron block 24, drives storage hood 23 to reciprocate, facilitating the reciprocating movement of calcium hydroxide desulfurizing agent within storage hood 23, thus ensuring sufficient contact between the calcium hydroxide desulfurizing agent and the hot airflow.To avoid localized temperature differences in the calcium hydroxide desulfurizing agent affecting the drying effect, after drying is complete, the stepper motor 25 stops rotating, the electromagnet 2 is de-energized, the electromagnet 2 is disconnected from the iron block 24, and the servo motor 11 continues to move the conveyor storage hood 23. This achieves convenient reciprocating moving drying operation of the calcium hydroxide desulfurizing agent, ensuring sufficient contact between the calcium hydroxide desulfurizing agent and the hot airflow, avoiding localized temperature differences that could affect the drying effect, improving the quality and efficiency of the calcium hydroxide desulfurizing agent drying, and completing the operation of the drying equipment.
