Description

Technical Field

[0001] This utility model belongs to the field of calcite drying technology, and in particular relates to a calcite drying device. Background Technology

[0002] Calcite drying equipment utilizes the principle of heat transfer, allowing hot air, conductive heat, or radiant heat to fully contact the wet calcite, causing the free water or crystal water in the material to absorb heat and vaporize. The water vapor is then discharged by a fan, ultimately achieving material drying.

[0003] The conventional equipment used for drying calcite is the rotary drum dryer, which is a tilted rotating cylinder. The hot airflow comes into contact with the material inside the cylinder to complete the heat transfer. In the process of processing calcite, sometimes it is not possible to directly use the hot airflow for heat transfer, and heat exchange pipes are needed for heat transfer. In the existing design of drying devices, the heat exchange pipes are mostly welded directly inside the rotary drum. Unlike powder materials, the tumbling of calcite materials during the drying process can easily cause impact damage to the heat exchange pipes. After the heat exchange pipes fail, they are not easy to separate from the rotary drum, making maintenance difficult. Utility Model Content

[0021] This utility model embodiment provides a calcite drying device, such as... Figures 1-6 As shown, the calcite drying device includes: The equipment includes a drying feed mechanism 110 and a dryer discharge mechanism 120. A dryer cylinder 200 is located between the drying feed mechanism 110 and the dryer discharge mechanism 120. The drying feed mechanism 110 and the dryer discharge mechanism 120 are rotatably connected to the dryer cylinder 200. The structure of the dryer discharge mechanism 120 and the dryer cylinder 200 is basically the same as that of the prior art. The dryer cylinder 200 rotates through a toothed ring on its outer wall and a drive motor. The dryer discharge mechanism 120 is connected to the dryer cylinder 200 through a shaft collar structure. The top of the dryer discharge mechanism 120 is equipped with a recovery device for recovering dust and flue gas. The overall structure of the drying feed mechanism 110 is basically the same as that of the prior art. The top of the drying feed mechanism 110 is equipped with a feed component for receiving calcite. The structure of the feed component is basically the same as that of the prior art. The end of the feed component extends into the dryer cylinder 200. A heat-conducting pipe fitting 300 includes a main rod 310, several sets of secondary rods 320, and support rods 330. The secondary rods 320 are arranged in a ring array around the main rod 310. The main rod 310 and the secondary rods 320 are connected by the support rods 330. The heat-conducting pipe fitting 300 is provided with several sets of heat dissipation coils 340. The heat dissipation coils 340 are arranged in a rectangular area formed by the main rod 310 and the secondary rods 320. The main rod 310 has two sets of conveying channels communicating with the outside at its internal axis. The two sets of conveying channels are separated from each other at both ends. The two ends of the heat dissipation coils 340 are respectively connected to the conveying channels. The outer edges of the other bending points of the heat dissipation coils 340 are welded to the main rod 310 and the secondary rods 320. The heat dissipation coils 340 are connected through the main rod 310 and the secondary rods 320. The calcite drying device also includes a combustion device 500 for conveying hot air. The heat-conducting pipe 300 is assembled to the drying feeding mechanism 110 via a bearing. The heat-conducting pipe 300 is inserted into the drying drum 200. The heat-conducting pipe 300 and the drying drum 200 are provided with a movable support 430 for supporting the heat-conducting pipe 300. In this application, the heat-conducting pipe 300 and the drying feeding mechanism 110 are rotatably connected using a bearing structure. Here, the heat-conducting pipe 300 and the drying feeding mechanism 110 are fixedly connected via an interference fit or other means on the inner edge of the bearing structure, allowing the heat-conducting pipe 300 and the drying feeding mechanism 110 to move synchronously. The heat-conducting pipe 300 is withdrawn from the drying cylinder 200 as the drying feeding mechanism 110 moves away from the drying cylinder 200. Here, the movable bracket 430 and the heat-conducting pipe 300 are connected by a simple plug-in joint. The movable support 430 has a shaped insertion hole at its center. The heat-conducting pipe 300 transmits torque to the movable support 430 through the shaped insertion hole. After being inserted and connected, the heat-conducting pipe 300 can rotate synchronously with the dryer drum 200. The insertion structure design of the heat-conducting pipe 300 in this application allows the heat-conducting pipe 300 to be disassembled synchronously with the drying feeding mechanism 110, thereby allowing the heat-conducting pipe 300 located inside the dryer drum 200 to be separated efficiently, making the heat-conducting pipe 300 easier to maintain and repair. In a preferred embodiment of this invention, the main rod 310 includes a front support rod 311, an inner rod body 312, and a rear support rod 313. Conveying channels are arranged inside the front support rod 311 and the rear support rod 313. The two sets of conveying channels extend into the inner rod body 312. The two ends of the heat dissipation coil 340 are connected to the portions of the two sets of conveying channels that extend into the inner rod body 312. The front support rod 311 extends out to form a drying feeding mechanism 110. The front support rod 311 is connected to the combustion device 500 through a rotary joint and a bend. The high-temperature gas from the combustion device 500 is introduced into the main rod 310 through the front support rod 311. The bend design here is mainly to facilitate the separation of the drying feeding mechanism 110.

[0022] In this embodiment, the drying feeding mechanism 110 has a fixed bearing on its housing. The main rod 310 passes through the fixed bearing and exits the housing of the drying feeding mechanism 110. The drying feeding mechanism 110 also has a fixed bracket 410 inside. The main rod 310 is assembled on the fixed bracket 410 through the bearing. The fixed bracket 410 includes a first assembly frame 411 and a connecting rod 412. The first assembly frame 411 has a bearing at its center for assembling the front support rod 311. There are three sets of connecting rods 412, which are designed at an angle. The first assembly frame 411 and the connecting rods 412 need to be set to avoid the feeding part position. As a preferred embodiment of this embodiment, the movable support 430 includes a first movable frame 431, a second movable frame 432 and several sets of tripods 433. One end of the tripod 433 is fixedly connected to the inner wall of the dryer drum 200, and the other two ends of the tripod 433 are respectively connected to the first movable frame 431 and the second movable frame 432. In this embodiment, the first movable frame 431 and the second movable frame 432 are respectively provided with a first insertion hole and a second insertion hole at their center. The first insertion hole and the second insertion hole adopt an arc-shaped structure, and the axial positions of the first insertion hole and the second insertion hole coincide with each other. The movable bracket 430 helps to transmit the torque of the dryer cylinder 200 to the heat-conducting pipe 300.

[0023] In a further preferred embodiment of this utility model, the rear support rod 313 is further provided with an exhaust pipe 350 at its end. The exhaust pipe 350 is connected to the rear support rod 313 through a rotary joint. The exhaust pipe is connected to the inner wall of the dryer discharge mechanism 120 housing by a bracket. The exhaust pipe 350 mainly guides the exhaust gas that has dissipated heat to the dust and flue gas recovery equipment located at the top of the dryer discharge mechanism 120 as much as possible, so as to avoid the exhaust gas directly remaining inside the dryer discharge mechanism 120 housing. The end of the exhaust pipe 350 can extend directly into the pipe opening of the dust recovery equipment. The dryer discharge mechanism 120 needs to be provided with a disassembly port 150. The disassembly port 150 is covered by a cover plate. After the cover plate is removed, the rotary joint connecting the exhaust pipe 350 and the rear support rod 313 can be disassembled, so that the heat conduction pipe 300 can be extracted.

[0024] In this utility model, the bottom of the drying feeding mechanism 110 is also provided with a guide groove 101. After the drying feeding mechanism 110 and the dryer cylinder 200 are separated and disassembled, the guide groove 101 can be pulled away from the dryer cylinder 200 by horizontal sliding. The heat-conducting pipe 300 assembled on the drying feeding mechanism 110 will be pulled away from the dryer cylinder 200 at the same time, which facilitates the maintenance of the heat-conducting pipe 300. The connection between the drying feeding mechanism 110 and the dryer cylinder 200 and the connection between the dryer cylinder 200 and the dryer discharge mechanism 120 are still achieved by using the existing drying equipment technology, and the disassembly process is the same. This application mainly modifies the drying feeding mechanism 110 so that the drying feeding mechanism 110 and the heat-conducting pipe 300 become an integrated structure, so that the heat-conducting pipe 300 can be easily separated from the dryer cylinder 200. The dryer cylinder 200 is provided with a guide plate to pull calcite from the drying feeding mechanism 110 to the side of the dryer discharge mechanism 120. In this application, the above structure adopts a co-current drying method. If a counter-current drying method is adopted, the exhaust pipe 350 needs to be connected to the front support rod 311 through a rotary joint. The end of the exhaust pipe 350 is directly connected to the exhaust gas treatment equipment. The rear support rod 313 needs to be connected to the combustion equipment 500 through a rotary joint and a pipe. Here, the dryer discharge mechanism 120 still relies on the disassembly port 150 to help the rotary joint with the combustion equipment 500 be separated from the rear support rod 313, so that the heat conduction pipe 300 can be extracted.
