Description

Technical Field

[0001] This utility model relates to the field of pellet processing equipment technology, and in particular to a moisture-absorbing and drying device for the discharge port of a pellet mill. Background Technology

[0002] Pellet mills play a vital role in production processes in industries such as agriculture, feed processing, and biomass energy. The pellets produced are typically at a high temperature and have a certain moisture content when they are first discharged. To ensure the pellets' hardness, molding quality, and ease of subsequent packaging and storage, a drying device is usually installed at the pellet mill's discharge port to absorb moisture and dry the pellets.

[0003] However, in actual production operations, existing pellet mill discharge drying devices still have significant structural defects. Firstly, during long-term operation, material debris, dust, and condensate scale easily accumulate at the bottom of the drying chamber, requiring operators to regularly clean and maintain the device. However, existing drying devices often use bolted or welded connections between the base and the main body. This rigid connection structure makes disassembly extremely cumbersome, often requiring operators to use wrenches and other specialized tools, spending considerable time to remove the base. This severely impacts equipment maintenance efficiency and production continuity.

[0004] Secondly, during the drying process, the material evaporates a large amount of water vapor when heated. If this water vapor cannot be discharged in a timely and controlled manner, it is very easy for it to condense and drip from the top of the device or be reabsorbed by the particles, thus affecting the drying effect. Existing devices often lack effective dehumidification control mechanisms, making it difficult to efficiently remove moisture while maintaining the heat of the drying chamber. Furthermore, traditional dehumidification structures are often independent of or conflict with cleaning structures, failing to balance ease of operation and complete functionality.

[0005] Therefore, this utility model proposes a moisture-absorbing and drying device for the discharge port of a pellet mill to overcome the shortcomings of the prior art. Utility Model Content

[0023] Reference Figures 1-5 The present invention provides an embodiment of a moisture-absorbing drying device for the discharge port of a pellet mill, which aims to solve the structural defects in the prior art, namely, the difficulty in efficiently discharging water vapor generated after pellet drying and the difficulty in quickly disassembling the device base and drying chamber, resulting in difficulties in internal cleaning and maintenance.

[0024] The pellet mill discharge outlet moisture-absorbing and drying device includes a support assembly 1 as a basic support, an adjustment assembly 2 for automatic moisture dehumidification control, and a connection assembly 3 for quick assembly, disassembly, and locking. The support assembly 1 mainly consists of a base 101, a discharge outlet 102, and a support frame 103. The base 101 serves as the mounting base for the entire device and is located at the bottom. A connecting groove 306 is formed at the top of the base 101, extending along its depth. The support frame 103 is positioned above the base 101, and a connecting column 30 is fixedly connected to the bottom of the support frame 103. 4. The connecting column 304 extends vertically downward and is inserted into the connecting groove 306. The cross-sectional shape of the connecting column 304 is adapted to the cross-sectional shape of the connecting groove 306. The connecting column 304 and the connecting groove 306 form a sliding fit. The outer wall of the connecting column 304 is provided with an annular limiting groove 305. The connecting component 3 is set on the outer wall of the support frame 103 and cooperates with the limiting groove 305 to lock the connecting column 304. The discharge port 102 is fixedly connected to the top of the support frame 103 and the discharge port 102 is connected to the internal space of the support frame 103. The particles enter the internal area of ​​the support frame 103 through the discharge port 102. The adjustment components 2 are distributed and installed inside the support frame 103 and on the outer wall of the base 101. The controller 203 is fixedly installed on the outer wall of the base 101. The controller 203 is electrically connected to each electrical component in the adjustment components 2. Through the cooperation of the support components 1, the adjustment components 2 and the connecting components 3, a device integrating drying, dehumidification and convenient maintenance is constructed.

[0025] The pellet mill discharge outlet moisture-absorbing drying device also includes a connecting component 3. The connecting component 3 and the aforementioned support component 1 form a specific quick-unlocking and locking structural fit and connection relationship. The connecting component 3 mainly consists of a connecting plate 301, a sliding column 302, a limiting column 303, a hollow tube 307, and a tension spring 308. The hollow tube 307 has a cylindrical structure extending along its length. The hollow tube 307 is bolted to the outer wall of the support frame 103 through mounting holes at both ends. Its function is to provide precise guidance and limiting for the movement of the sliding column 302. The sliding column 302 has a cylindrical structure adapted to the internal structure of the hollow tube 307. The sliding column 302 is slidably connected inside the hollow tube 307. The tension spring 308 is located inside the hollow tube. Inside the tube 307, one end of the tension spring 308 is fixedly connected to the inner wall of the hollow tube 307, and the other end of the tension spring 308 is fixedly connected to the end of the sliding column 302 located inside the hollow tube 307. The tension spring 308 is used to provide a restoring force for the connecting plate 301 to ensure that the connecting plate 301 automatically resets after release. The connecting plate 301 is fixedly connected to the outer end of the sliding column 302. The connecting plate 301 is used by the operator to operate the connecting assembly 3. The limiting column 303 is provided with a fixing structure adapted to the connecting plate 301. The limiting column 303 is fixedly connected to the side of the connecting plate 301 near the connecting column 304. The limiting column 303 and the sliding column 302 are arranged parallel to each other, and the limiting column 303 and the sliding column 302 are both vertically fixedly connected to the same side of the connecting plate 301. In the locked state, the end of the limiting post 303 away from the connecting plate 301 passes through the support frame 103 and is engaged in the annular limiting groove 305 on the outer wall of the connecting post 304. The limiting post 303 is engaged in the limiting groove 305, thereby locking the connection between the connecting post 304 and the connecting groove 306, ensuring the stability of the connection between the base 101 and the support frame 103. The spring-loaded locking structure composed of the connecting plate 301, the sliding post 302, the tension spring 308 and the limiting post 303 ensures that when cleaning is required, the operator only needs to pull the connecting plate 301 outward to release the locking of the limiting post 303 to the limiting groove 305, realizing the quick disassembly of the base 101, which greatly facilitates the cleaning and maintenance of the drying chamber. Meanwhile, the power source used to drive particle drying, such as an electric heating device, can be implemented by those skilled in the art using various conventional methods such as resistance wires and heating plates. Its specific internal structure is well-known in the field and will not be described in detail here.

[0026] To achieve automatic reset and locking of the connecting plate 301, a tension spring 308 is installed inside the hollow tube 307. One end of the tension spring 308 is fixedly connected to the inner wall of the hollow tube 307, and the other end of the tension spring 308 is fixedly connected to the end of the sliding column 302 located inside the hollow tube 307. When the connecting plate 301 is subjected to an outward pulling force, the sliding column 302 slides outward along the hollow tube 307 and stretches the tension spring 308. When the external force is released, the tension spring 308 contracts and drives the sliding column 302 to reset. To achieve efficient forced dehumidification, the motor 201 is fixedly installed at the top of the support frame 103, and the electric fan 202 is fixedly connected to the output shaft of the motor 201. The electric fan 202 is positioned directly opposite the ventilation pipe 207 to ensure smooth airflow.

[0027] For easy centralized control, the controller 203 is fixedly installed on the outer side wall of the base 101. The controller 203 is electrically connected to the motor 201 and the electric push rod 204 respectively, and is used to control the start and stop of the dehumidification process. In order to facilitate the entry of particles into the drying chamber, the discharge port 102 is fixedly connected to the top of the support frame 103, and the discharge port 102 is connected to the internal space of the support frame 103.

[0028] To achieve precise opening and closing of the baffle 206, the electric push rod 204 is installed vertically downwards, and the push block 205 is configured to drive the baffle 206 to slide vertically under the drive of the electric push rod 204, thereby precisely controlling the opening and closing of the ventilation pipe 207. In order to ensure the smooth operation of the connecting plate 301 and the stability of the structure, the sliding column 302 and the limiting column 303 are arranged parallel to each other, and the sliding column 302 and the limiting column 303 are both vertically fixed to the same side of the connecting plate 301.

[0029] To ensure the guidance and stability of the connection between the base 101 and the support frame 103, the connecting groove 306 is opened inside the base 101, and the cross-sectional shape of the connecting post 304 is adapted to the cross-sectional shape of the connecting groove 306, so that the connecting post 304 and the connecting groove 306 form a tight sliding fit.

[0030] Working principle: First, the particles enter the drying chamber of the device through the discharge port 102 on the support component 1. Then, the drying chamber is heated by electric heating. After the drying chamber is heated, the particles in the drying chamber are dried and absorb moisture. After drying, the water vapor dried in the device is discharged from the device through the adjustment component 2 to prevent the water vapor from affecting the subsequent drying. After the particles have finished drying and absorbing moisture, the discharge port 102 of the device is removed through the connection component 3 to clean the drying chamber inside the device.

[0031] During operation, the particles enter the drying chamber inside the device through the discharge port 102 on the support assembly 1. The internal electric heating device is activated to heat the drying chamber, and the high temperature dries and absorbs moisture from the particles inside the drying chamber. After drying is completed, the controller 203 fixed on the outer wall of the base 101 is activated. The controller 203 drives the electric push rod 204 to work. The electric push rod 204 pushes the push block 205 connected at the top to slide upward in the support frame 103. The push block 205 drives the fixed baffle 206 to slide upward in the support frame 103. When the baffle 206 slides upward to the position where it no longer blocks the opening of the ventilation pipe 207, the controller 203 is turned off. Then the motor 201 is started. The motor 201 drives the electric fan 202 installed in the support frame 103 to rotate. The electric fan 202 generates airflow to force the water vapor generated by moisture absorption in the drying chamber out of the device through the opened ventilation pipe 207 to prevent the water vapor from affecting the subsequent drying effect.

[0032] When the drying chamber needs to be cleaned after the granules have finished drying and absorbing moisture, the operator pulls the connecting plate 301 outward. The connecting plate 301 drives the sliding column 302 to slide outward in the hollow tube 307 against the tension of the tension spring 308. This action causes the limiting column 303 fixed on the connecting plate 301 to disengage from the limiting groove 305 on the connecting column 304, thus releasing the locking state. Then, the connecting column 304 is removed from the connecting groove 306 in the base 101, separating the base 101 from the main body of the equipment, which facilitates a thorough cleaning of the drying chamber inside the device. After cleaning, the base 101 is reinstalled, the connecting column 304 is inserted into the connecting groove 306, the connecting plate 301 is released, the tension spring 308 resets, and the sliding column 302 retracts, causing the limiting column 303 to re-engage in the limiting groove 305 to complete the locking. The device can then continue to work.
