Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate technology, specifically to a drying device for calcium carbonate processing. Background Technology

[0002] Calcium carbonate is an inorganic compound, and it is the main component of common marble and limestone. As a substance that is relatively abundant in nature, its unique physical and chemical properties make it commonly used in the production of building materials. During the processing of calcium carbonate, it is necessary to clean and dry the crushed calcium carbonate. However, some lumps will remain inside the cleaned calcium carbonate. However, some existing drying equipment cannot crush the lumps of calcium carbonate during use, causing some completely crushed and lumpy calcium carbonate to mix together, resulting in insufficient drying. Since most of the calcium carbonate is piled up for drying, its internal fluidity is not strong, which means that the calcium carbonate inside the dryer needs a long time to be completely dried, resulting in low drying efficiency. Utility Model Content

[0003] In view of this, the present invention provides a drying device for calcium carbonate processing, which can crush agglomerated calcium carbonate before drying to achieve more thorough drying, and improve the air circulation inside the calcium carbonate by stirring it during drying, thereby improving drying efficiency and shortening drying time.

[0004] To solve the above-mentioned technical problems, this utility model provides a drying device for calcium carbonate processing, including a box and a heater. A feed pipe is provided at the top of the box, and a discharge pipe is provided at the bottom of the box. A valve is installed inside the discharge pipe. A crushing mechanism is located at the top inside the box, including two crushing rollers and a drive assembly. The drive assembly drives the two crushing rollers to rotate. A drying mechanism is located at the bottom inside the box, including a rotating rod and a heater. Several stirring rods are provided on the surface of the rotating rod. The drying mechanism also includes a rotating assembly that drives the rotating rod to rotate. The operator then applies calcium carbonate... The calcium carbonate is poured into the feed pipe and falls into the crusher mechanism. Then, the drive component drives two crushing rollers to rotate, which crushes the lumps inside the calcium carbonate. The crushed calcium carbonate enters the drying mechanism, where it is heated by a heater. At the same time, the rotating component drives the rotating rod to rotate, which in turn drives the stirring rod to stir the calcium carbonate. This process crushes the lumps of calcium carbonate before drying, allowing for more thorough drying. Furthermore, stirring during the drying process improves air circulation inside the calcium carbonate, thereby increasing drying efficiency and shortening drying time.

[0005] The crushing mechanism also includes a crushing chamber located at the top of the box, with two crushing rollers rotating inside the crushing chamber. The drying mechanism includes a drying chamber located at the bottom of the box, with a heater located above the two inner side walls of the drying chamber. A rotating rod is located at the center of the inner side wall of the drying chamber. A guide chute is provided on the lower side of the inner wall of the crushing chamber and is connected to the drying chamber. The operator pours calcium carbonate into the crushing chamber through the feed pipe, so that the calcium carbonate falls between the two crushing rollers. After the calcium carbonate is crushed, it passes through the guide chute and falls into the drying chamber. Because the lower part of the drying chamber is semi-circular, the calcium carbonate can be fully stirred without any dead corners.

[0006] The drive assembly includes a drive frame mounted on one side wall of the housing. Inside the drive frame, two gears are rotatably mounted on both sides and are meshed together. One end of each gear is connected to the center of the end of its corresponding crushing roller. A motor is mounted on one side of the drive frame. The fixed end of the motor is fixed to the side wall of the drive frame, and the output end of the motor passes through the side wall of the drive frame and is connected to the center of the end of one of the gears. When the operator starts the motor, the output end of the motor drives one of the gears to rotate. Since the two gears are meshed, they rotate simultaneously, thereby causing the two gears to drive the two crushing rollers to rotate synchronously.

[0007] The rotating assembly includes a drive sprocket rotatably mounted on the other side of the drive frame surface. The end of the drive sprocket is connected to the center of the end of another gear. A driven sprocket is rotatably mounted on the outer wall of the housing, corresponding to the end of the rotating rod. The end of the driven sprocket is connected to the center of the end of the rotating rod. The surfaces of the drive sprocket and the driven sprocket are connected by a chain. The stirring rods on the surfaces of the rotating rods are staggered. When one of the gears rotates, one of the gears drives the drive sprocket to rotate. The drive sprocket drives the driven sprocket to rotate via the chain. The driven sprocket drives the rotating rod to rotate, thereby causing the stirring rod to stir the calcium carbonate.

[0008] The surface of the crushing roller is uniformly provided with several raised strips, which can improve the crushing effect of the crushing roller on calcium carbonate agglomerates.

[0009] An exhaust pipe is installed on the other side wall of the chamber. When the calcium carbonate is heated and dried by the heater, the water vapor it emits is discharged into the drying chamber through the exhaust pipe.

[0010] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0011] 1. In use of this utility model, the operator pours calcium carbonate into the feed pipe, allowing it to fall into the crusher mechanism. Then, the drive component drives two crushing rollers to rotate, causing the crushing rollers to crush the lumps inside the calcium carbonate. The crushed calcium carbonate then enters the drying mechanism, where it is dried and heated by a heater. Simultaneously, the rotating component drives the rotating rod to rotate, which in turn drives the stirring rod to stir the calcium carbonate. This process crushes the lumps of calcium carbonate before drying, resulting in more thorough drying. Furthermore, the stirring during the drying process improves air circulation inside the calcium carbonate, thereby increasing drying efficiency and shortening drying time.

[0012] 2. When using this utility model, the worker pours calcium carbonate into the crushing chamber through the feed pipe, so that the calcium carbonate falls between the two crushing rollers. After the calcium carbonate is crushed, it passes through the guide trough and falls into the drying chamber. Since the lower part of the drying chamber is semi-circular, the calcium carbonate can be fully stirred without any dead corners.

[0013] 3. When using this utility model, the operator starts the motor, and the output end of the motor drives one of the gears to rotate. Since the two gears mesh with each other, the two gears will rotate at the same time, which in turn drives the two crushing rollers to rotate synchronously.

[0014] 4. When this utility model is in use, when one of the gears rotates, one of the gears drives the drive sprocket to rotate, the drive sprocket drives the driven sprocket to rotate through the chain, and the driven sprocket drives the rotating rod to rotate, thereby causing the stirring rod to stir the calcium carbonate.

[0021] According to one embodiment of the present invention, such as Figure 1-4 As shown: This embodiment provides a drying device for calcium carbonate processing, including a housing 100 and a heater 400. A feed pipe 101 is provided at the upper part of the housing 100, and a discharge pipe 102 is provided at the lower part of the housing 100. A valve is installed inside the discharge pipe 102. A crushing mechanism is provided at the upper part inside the housing 100, including two crushing rollers 201 and a drive assembly. The drive assembly drives the two crushing rollers 201 to rotate. A drying mechanism is provided at the lower part inside the housing 100, including a rotating rod 301 and a heater 400. A plurality of stirring rods 302 are provided on the surface of the rotating rod 301. The drying mechanism also includes a rotating assembly for driving the rotating rod 301 to rotate. The operator pours calcium carbonate into the feed pipe 101, allowing it to fall into the crusher mechanism. The drive assembly then rotates two crushing rollers 201, which crush any clumps inside the calcium carbonate. The crushed calcium carbonate then enters the drying mechanism, where it is heated by the heater 400. Simultaneously, the rotating assembly drives the rotating rod 301 to rotate, which in turn drives the stirring rod 302 to agitate the calcium carbonate. This process crushes the clumps before drying, ensuring more thorough drying. Furthermore, the agitation during drying improves air circulation within the calcium carbonate, thereby increasing drying efficiency and shortening drying time.

[0022] The crushing mechanism also includes a crushing chamber 200 located above the interior of the housing 100, with two crushing rollers 201 rotatably disposed inside the crushing chamber 200. The drying mechanism includes a drying chamber 300 located below the interior of the housing 100, with a heater 400 disposed above the two inner side walls of the drying chamber 300. A rotating rod 301 is rotatably disposed at the center of the inner side wall of the drying chamber 300. A guide trough 202 is provided on the lower side of the inner wall of the crushing chamber 200 and is connected to the drying chamber 300. The operator pours calcium carbonate into the crushing chamber 200 through the feed pipe 101, so that the calcium carbonate falls between the two crushing rollers 201. After the calcium carbonate is crushed, it passes through the guide trough 202 and falls into the drying chamber 300. Since the lower part of the drying chamber 300 is semi-circular, the calcium carbonate can be fully stirred without any dead corners.

[0023] The drive assembly includes a drive frame 203 mounted on one side wall of the housing 100. Two gears 205 are rotatably mounted on both sides inside the drive frame 203 and are meshed together. One end of each gear 205 is connected to the center of the end of its corresponding crushing roller 201. A motor 204 is mounted on one side of the surface of the drive frame 203. The fixed end of the motor 204 is fixed to the side wall of the drive frame 203. The output end of the motor 204 passes through the side wall of the drive frame 203 and is connected to the center of the end of one of the gears 205. When the operator starts the motor 204, the output end of the motor 204 drives one of the gears 205 to rotate. Since the two gears 205 are meshed together, they rotate simultaneously, thereby driving the two crushing rollers 201 to rotate synchronously.

[0024] The rotating assembly includes a drive sprocket 304 rotatably disposed on the other side of the surface of the drive frame 203. The end of the drive sprocket 304 is connected to the center of the end of another gear 205. On the outer wall of the housing 100, a driven sprocket 303 is rotatably disposed at the position corresponding to the end of the rotating rod 301. The end of the driven sprocket 303 is connected to the center of the end of the rotating rod 301. The surfaces of the drive sprocket 304 and the driven sprocket 303 are connected by a chain 305. The stirring rod 302 on the surface of the rotating rod 301 is staggered. When one of the gears 205 rotates, one of the gears 205 drives the drive sprocket 304 to rotate. The drive sprocket 304 drives the driven sprocket 303 to rotate through the chain 305. The driven sprocket 303 drives the rotating rod 301 to rotate, thereby causing the stirring rod 302 to stir the calcium carbonate.

[0025] The surface of the crushing roller 201 is uniformly provided with several raised strips, which can improve the crushing effect of the crushing roller 201 on calcium carbonate agglomerates;

[0026] An exhaust pipe 103 is provided on the other side wall of the chamber 100. When the calcium carbonate is heated and dried by the heater 400, the water vapor emitted by it is discharged into the drying chamber 300 through the exhaust pipe 103.

[0027] How to use this utility model:

[0028] First, it needs to be clarified that this utility model mainly relates to the crushing and drying of calcium carbonate clumps. It should be noted that the heating machine 400 is a common drying device in the prior art. Since it is not a key technical feature of this utility model, its model will not be limited, nor will its structure be described in detail. Only the usage and installation position of the drying and crushing mechanisms will be described in detail. When calcium carbonate needs to be dried, the operator pours the calcium carbonate into the crushing chamber 200 through the feed pipe 101, causing the calcium carbonate to fall between the two crushing rollers 201. Then, the motor 204 is started. The output of the motor 204 drives one of the gears 205 to rotate. Because the two gears 205 mesh with each other, they rotate simultaneously, thereby driving the two crushing rollers 201 to rotate synchronously. 1. The lumps inside the calcium carbonate are crushed, allowing for more thorough drying before drying. The crushed calcium carbonate enters the drying chamber 300 through the feed chute 202. Then, the heater 400 is started to heat and dry the calcium carbonate. The water vapor generated during drying is discharged through the exhaust pipe 103. When the gears 205 rotate, one of the gears 205 drives the drive sprocket 304 to rotate. The drive sprocket 304 drives the driven sprocket 303 to rotate through the chain 305. The driven sprocket 303 drives the rotating rod 301 to rotate, causing the stirring rod 302 to stir the calcium carbonate. This allows the calcium carbonate to be dried while being stirred, improving the air circulation inside the calcium carbonate, thereby improving drying efficiency and shortening the drying time. After the calcium carbonate is dried, the valve of the discharge pipe 102 is opened to discharge the calcium carbonate from the discharge pipe 102.

[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
