Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a wood drying machine. Background Art

[0002] Wood dryer is a common wood processing equipment, which is used to dry wood with high humidity by hot air or vacuum to achieve a certain moisture content requirement. Wood drying methods can be divided into natural ventilation and forced ventilation according to the source of hot air. Natural ventilation dryer uses natural wind to introduce outside air into the machine to evaporate the moisture on the surface of the wood, but this method has a slow drying speed and is not suitable for large-scale drying. Forced ventilation dryer uses a fan to heat the outside air and send it into the machine to evaporate the moisture on the surface of the wood, and then discharge the moisture out of the machine. Due to the high moisture content on the surface of the wood with high humidity, wood chips are more likely to adhere to its surface, but as the wood is continuously dried, its moisture content will decrease, and then the adhesion between wood chips and wood will also decrease. At the same time, the fan conveys the flow of hot air, and then blows the wood chips adhered to the surface of the wood into the dryer, which may cause wood chips to accumulate inside the dryer and cause blockage of the ventilation duct, affecting the circulation of hot air, thereby affecting the drying effect. Utility Model Content

[0003] In view of this, and in view of the deficiencies in the prior art, the utility model provides a wood drying machine to solve the problem that wood chips on the wood surface are blown by hot air during the wood drying process, resulting in blockage of the ventilation duct.

[0014] 1. By setting up the collection box, filter, air bag and scraper, the wood chips can be carried to the collection box by hot air.

[0037] Further Embodiments

[0038] Please refer to Figures 5 to 7 As shown in the figure: the filter 4021 is arranged inside the circular opening opened on the inner wall of one side of the collection box 404, and is used to prevent the wood chips from being directly discharged into the external environment; the exhaust pipe 4022 is installed on the outer wall of the collection box 404, and the exhaust pipe 4022 is located outside the circular opening. The collection box 404 is fixedly connected with the exhaust pipe 103 by bolts, which facilitates the quick disassembly and installation of the collection box 404 and can centrally process the wood chips in the collection box 404.

[0039] It is worth mentioning that the airbag 4031 is installed on the inner wall of the collection box 404, wherein the temperature range of the factory when drying wood is between 60 and 70 degrees Celsius, and the airbag 4031 is made of nitrile rubber material, and its heat resistance temperature is above 200 degrees Celsius, so that the airbag 4031 can work in the collection box 404; the airbag 4031 is deformed by the pressure squeezed in the collection box 404 to realize the removal of wood chips on the filter 4021; a connecting rod 4032 is provided on the outer surface of the airbag 4031, and a scraper 4033 is installed at the end of the connecting rod 4032 away from the airbag 4031, wherein the bottom of the scraper 4033 is in contact with the filter 4021, and limit rods 4034 are provided on the upper and lower sides of the scraper 4033, and the limit rods 4034 are slidably set on the upper and lower inner walls of the collection box 404, which are used to limit the movement direction and range of the scraper 4033. The airbag 4031 is made of rubber material, which not only has good elastic deformation, but also can prevent wood chips from damaging the outer surface of the airbag 4031.

[0040] Everything in the above example works like this:

[0041] When in use, the staff first opens the tank door 101, and then the staff engages the front end of the wood conveying track with the connecting groove 202 on the slide rail 2, which can facilitate the staff to quickly dock and push the wood into the tank body 1. Then the staff pushes the rack 201 on which the wood to be dried is placed into the tank body 1 and fixes the rack 201. The multiple limit columns provided on the rack 201 can prevent the wood from sliding due to heat shrinkage and deformation during the drying process. The hollow bottom plate provided on the rack 201 can effectively increase the contact area between the wood and the hot air, which can promote more uniform drying of the wood, thereby improving the drying effect of the wood. Then the tank door 101 is closed and sealed.

[0042] Furthermore, outside air is introduced through the output pipe of the external fan at the top of the air inlet pipe 102. When the outside air enters the tank body 1 through the air inlet pipe 102, the impact force of the outside air flow first contacts the curved plate 302. The curved plate 302 is relatively rotated downward along the mounting frame 301 under the pressure of the outside air. At this time, the torsion spring 303 installed on one side of the curved plate 302 gradually shrinks, and the impact ball 304 on the curved plate 302 also gradually moves away from the top of the arc of the tank body 1. The outside air is affected by the curved structure on the surface of the curved plate 302, and the hot air is guided to the top of the arc in the tank body 1. At the same time, the curved plate 302 is rotated upward by the impact of the outside air, and the wind direction of the hot air is caused to gradually move downward. Then the curved plate 302 moves downward During the rotation, the gap between the arc plate 302 and the inner wall of the tank body 1 increases, so that the pressure of the outside air decreases, and then the torsion spring 303 gradually opens and resets, and drives the arc plate 302 to rotate in the opposite direction, and at the same time, the impact ball 304 on the arc plate 302 also resets and hits the inner wall of the tank body 1, and the arc plate 302 performs a reciprocating swing motion under the interaction of the outside air and the torsion spring 303, so that the hot air direction can swing back and forth, which is conducive to the hot air being able to flush back and forth between the gaps in the wood, effectively improving the wood drying effect, and the reciprocating swinging hot air continuously blows to the surface of the tank body 1 to flush away the wood chips adsorbed on the inner wall of the tank body 1, avoiding the wood chips being adsorbed in the tank body 1 and affecting the wood drying effect;

[0043] As the wood is continuously dried, the moisture content of the wood inside the tank body 1 is continuously reduced, and the wood chips on the surface of the wood are gradually separated from the surface of the wood. Then, the wood chips enter the collection box 404 through the outlet pipe 103 at the bottom of the tank body 1 along with the hot air. At this time, the hot air passes through the filter 4021 and is discharged to the outside from the exhaust pipe 4022, and the wood chips carried by the hot air are blocked by the filter 4021. As the hot air is continuously discharged, the wood chips on the filter 4021 increase, thereby reducing the rate of hot air discharge, thereby making the inside of the collection box 404 The air pressure gradually increases, causing the air bag 4031 in the collection box 404 to shrink continuously due to the compression of the air pressure, and then the shrinkage of the air bag 4031 pulls the scraper 4033 fixedly connected to one end of the connecting rod 4032 to move toward the air bag 4031, and then when the scraper 4033 passes through the filter 4021, the bottom of the scraper 4033 scrapes off the wood chips accumulated on the surface of the filter 4021, and then restores the exhaust rate of the exhaust pipe 4022, which solves the problem of blockage of the dryer ventilation duct affecting the circulation of hot air, thereby effectively improving the effect of wood drying.
