Technical Field

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

[0002] In wood processing plants such as particleboard factories, the processing of wood products often generates waste sawdust. This waste sawdust has its own value, and it needs to be dried during recycling. Drying equipment is used to remove the moisture, resulting in dry sawdust.

[0003] CN212299675U discloses a drying device for waste wood chips, including two dryer side plates. A dryer base plate is fixedly connected to the bottom of the inner wall of the two dryer side plates. Each end of the dryer base plate is provided with a sliding groove fixedly connected to the bottom of the inner wall of the dryer side plate. A clamping plate is provided on the sliding groove and is slidably connected to the sliding groove. A heater is fixedly connected to the clamping plate. A motor is fixedly connected to the center of the dryer base plate. A rotating shaft is provided on the motor. The motor drive shaft is fixedly connected to the rotating shaft. A drying box is provided above the dryer base plate. The drying box is a rectangular box.

[0004] In use, existing devices are difficult to collect waste wood chips uniformly after drying. During the drying process, the waste wood chips inside the box are stationary, making it difficult for hot air to enter the gaps between the wood chips for drying. Furthermore, the moisture above the wood chips mixes with the high-temperature gas and easily forms steam. The steam is prone to condensation after rising, causing water droplets to fall onto the inside of the wood chips during the later collection process. Therefore, we propose a waste wood chip drying device. Utility Model Content

An exhaust pipe 21 is provided above the waste wood chip drying box, so that the internal gas pressure of the device is not too high.

[0027] An exhaust pipe 21 is fixedly installed on the front side of the waste wood chip drying box 1. One end of the transmission pipe 6 is fixedly installed on the rear side of the waste wood chip drying box 1. A wood chip collection drawer 7 is provided on the left side of the waste wood chip drying box 1. A fixing plate 8 is fixedly installed between the inner walls of the front and rear sides of the wood chip collection drawer 7.

[0029] The bevel gear 15 is fixedly installed on the outside of the drive shaft 12 and the movable shaft 14, and adjacent bevel gears 15 mesh with each other. The rotating block 16 is fixedly installed on the bottom of the movable shaft 14, the control protrusion 17 is fixedly installed on the bottom of the rotating block 16, and the force plate 18 is fixedly installed on the top of the rotating shaft 9.

[0030] In this embodiment, the drainage component includes a water collection tank 19 and a drainage pipe 20. The water collection tank 19 is fixedly installed on the inner walls of the left and right sides of the condensation plate 4, and the drainage pipe 20 is fixedly installed on the left and right sides of the front side of the condensation plate 4. The water collection tank 19 facilitates the collection and discharge of water, and the inclined water collection tank 19 makes it less likely for water to remain during the discharge process.

[0031] In this embodiment, the water collection tank 19 is inclined, and a through groove is opened on the front side of the condensation plate 4. The drainage pipe 20 is fixedly installed on the inner side of the through groove. The water collection tank 19 is connected to the through groove, and a solenoid valve is provided above the drainage pipe 20.

[0032] In this embodiment, a sliding groove is provided on the left side of the waste wood chip drying box 1, and the wood chip collection drawer 7 fits into the sliding groove. Limiting grooves are provided on the front and rear sides of the top of the sliding groove, and the outer diameter of the force plate 18 is smaller than the inner diameter of the limiting groove. The sliding groove facilitates the wood chip collection drawer 7 to slide into the inner side of the waste wood chip drying box 1. The limiting groove ensures that the force plate 18 can only enter the inner side of the waste wood chip drying box 1 vertically, so that the control protrusion 17 is less likely to interfere with the wood chip collection drawer 7 when the force plate 18 enters the waste wood chip drying box 1, and the control protrusion 17 can drive the force plate 18 to rotate when it rotates.

[0033] In this embodiment, the condensation plate 4 is triangular in shape, and the water collection tank 19 is connected to the condensation plate 4; so that the water droplets condensed on the top of the condensation plate 4 can flow out of the inner side of the water collection tank 19. The triangular condensation plate makes the water flow more convenient.

[0034] In this embodiment, multiple air inlets are provided on one side of the limiting partition 2 and the wood chip collection drawer 7. Rotating grooves are provided on the top of the mounting plate 13 and the fixing plate 8. The movable shaft 14 and the rotating shaft 9 are rotatably installed inside the rotating groove. The rotating groove facilitates the rotation of the movable shaft 14 and the rotating shaft 9, and the air inlets facilitate the entry of hot air into the inside of the waste wood chips for drying.

[0035] In this embodiment, the shape of the control protrusion 17 is cylindrical, and the length of the rotating block 16 is the same as the length of the force plate 18. After the rotating block 16 rotates, it can drive the force plate 18 to rotate through the control protrusion 17, so that the force plate 18 can drive the rotating shaft 9 and the stirring rod 10 to rotate, and the stirring rod 10 can turn over the waste wood chips.

[0036] The specific operation involves placing waste wood chips inside the wood chip collection drawer 7, allowing the drawer 7 to slide into the inside of the waste wood chip drying chamber 1. Hot air is then introduced into the drying chamber 1 via the hot air transfer pump 5 and transfer pipe 6 to dry the waste wood chips. Simultaneously, the motor 11 drives the drive shaft 12 to rotate, which in turn drives the movable shaft 14 via the bevel gear 15. The movable shaft 14, through the rotating block 16 and control protrusion 17, drives the force plate 18 to rotate under pressure. The rotating shaft 9 and the stirring rod 10 rotate, causing the stirring rod 10 to turn over the waste wood chips, making it easier for hot air to enter the gaps between the waste wood chips for drying. When the hot air inside dries the moisture inside the waste wood chips, the moisture easily heats up and turns into steam, rising to the top of the condensation plate 4 and condensing into water droplets. These water droplets can flow to the inside of the water collection tank 19. After drying is completed, the solenoid valve inside the drain pipe 20 can be opened to allow water to be discharged through the drain pipe 20.

[0037] The above provides a detailed description of a waste wood chip drying device provided by this utility model.
