Description

Technical Field

[0001] This utility model relates to the field of stem processing technology, specifically to a scraper rehydration device. Background Technology

[0002] Currently, the tobacco stem washing and scraper rehumidification processes are used in the tobacco stem processing to increase the moisture content and temperature of the tobacco stems, thereby improving their processing resistance. The stems are then stored in a storage tank and treated with SIROX for heating and humidification before being processed through pressing and cutting. The rehumidification effect directly affects the processing effect of the pressing process: a good rehumidification effect results in a high re-permeability rate, less stem breakage after pressing, and better cutting, leading to better quality stems after drying. Scraper-type rehumidification devices are typically used in the rehumidification process. However, existing scraper rehumidification devices suffer from wear and tear over long-term use, making replacement inconvenient or costly. Failure to replace the scrapers increases stem breakage. Furthermore, sticky substances accumulate on the scrapers over time, making them difficult to clean. To address these technical problems, this invention provides a scraper rehumidification device.

A partition 25 is connected in the gap between the U-shaped inner groove 21 and the housing 1. The partition 25 is located on both sides of the drainage holes 21a, thereby dividing the gap into a functional area 1d and a drainage area 1e. The drainage area 1e is located directly below the drainage holes 21a and a drain pipe 7 is provided at the bottom of the drainage area 1e to drain the water accumulated in the U-shaped inner groove 21. The functional area 1d is located on both sides of the drainage area 1e, and a heat insulation layer and / or a heating device are provided in the functional area 1d.

[0030] Two roller brush storage slots 1c are provided above the front sidewall 1a of the housing 1. The roller brush storage slots 1c protrude outward from the front sidewall 1a. A cover plate 12 is provided on the top of the housing 1. A straight module 11 is provided on the bottom surface of the cover plate 12. The straight module 11 is arranged along the length direction of the housing 1 and is located on the center line of the housing 1. Two roller brushes 9 are fixedly arranged on the slider 10 of the straight module 11. The circumferential surface of the roller brushes 9 is provided with brushes and the roller brushes 9 are located in the roller brush storage slots 1c. The distance between the two roller brushes 9 must be sufficient to allow the brushes to brush the front and rear sides of the scraper assembly 24 at the same time. When the roller brushes 9 are located in the roller brush storage slots 1c, it must be ensured that the roller brushes 9 do not affect the rotation of the scraper assembly 24.

[0031] The scraper assembly 24 includes a fixed scraper 24c and a scraper body 24a. The scraper body 24a is detachably connected to the end of the fixed scraper 24c and contacts the bottom surface of the U-shaped inner groove 21.

Furthermore, in order to discharge the material from the discharge port 4, an air pipe 19 is provided on the rear sidewall 1b. The bottom end of the air pipe 19 corresponds to the discharge port 4, and the upper end of the air pipe 19 is connected to a blower 14. The blower 14 generates airflow that blows through the air pipe 19 toward the discharge port 4, thereby blowing the material in the U-shaped inner groove 21 toward the discharge port 4. To prevent the material from being blown away after discharge, a bag can be placed on the U-shaped guide groove 5 to catch the material. The blower 14 is mounted on a cover plate 12, and a feed door 13 is also hinged to the cover plate 12.

[0036] To increase humidity and achieve rehumidification by introducing moisture into the material in the U-shaped inner trough 21, a moisture conveying pipe 20 is provided on the rear side wall 1b. Preferably, the moisture conveying pipe 20 is a U-shaped pipe with an air inlet for connection to an industrial humidifier. The moisture conveying pipe 20 extends laterally into the U-shaped inner trough 21 and has multiple air holes 20a spaced apart. The position of the moisture conveying pipe 20 must not interfere with the rotation of the scraper assembly 24. The air holes 20a face the bottom surface of the U-shaped inner trough 21. An inclined guard plate 22 is also provided on the inner wall of the U-shaped inner trough 21, and the inclined guard plate 22 is located above the moisture conveying pipe 20.

[0037] In some embodiments, a proximity switch 8 for detecting the arrival of the scraper assembly 24 is provided on the front sidewall 1a. The proximity switch 8 is located between the two roller brush storage slots 1c. In addition, the proximity switch 8 can be electrically connected to a prompting device. In actual use, when the scraper assembly 24 is rotated and the proximity switch 8 detects the side of the scraper assembly 24, a prompting signal is issued through the prompting device, at which time the linear module 11 can be activated.

[0038] The working process of this utility model is as follows: open the feed door 13 and add material into the U-shaped inner groove 21. Start the motor 15 to make the scraper assembly 24 rotate, thereby turning the material. Connect the air pipe 19 to the industrial humidifier so that the material can fully contact the moisture during the turning process to achieve the purpose of re-moistening. After the re-moistening is completed, turn on the blower 14 and use the air force to gradually discharge the material from the discharge port 4. When the scraper assembly 24 is worn, simply unscrew the screws and replace the scraper body 24a. When it is necessary to clean the scraper assembly 24, manually rotate the scraper assembly 24. When the scraper body 24a rotates to the position of the proximity switch 8, the proximity switch 8 sends a signal to the position. At this time, the linear module 11 is activated, and the two roller brushes 9 are located on the front and rear sides of the scraper body 24a and move back and forth in a straight line to clean the scraper body 24a.
