A variable heating and air supply device for drying and drying room

Abstract

The invention relates to an auxiliary device for wood drying and drying rooms, a variable heating and air supply device for drying and drying rooms. The rotating shaft (8) at the upper end of the fan (7) protrudes from the rectangular frame (6) and is fixedly connected to the chute rod ( 2) the rotating shaft hole (2a); a pair of guide rails (4) are fixed on one side of the rectangular frame (6), and a hydraulic cylinder (5) is configured on the guide rails (4), which can be manually or motorized on the guide rails (4) move; the push-pull direction of the piston push-pull rod (3) of the hydraulic cylinder (5) is consistent with the transverse length of the rectangular frame (6), and the position of the piston push-pull rod (3) corresponds to that of several parallel fans (7) , vertically fix several sliding rods (1), and the sliding rods (1) are inserted into the long slots (2b) of the chute rods (2). The invention has stable transmission, reduces faults, prolongs the service life, and easily realizes the speed and angle of forward and backward direction steering of multiple axial flow fans installed on the rectangular frame. It is very convenient to adjust the air supply status of hot air for various materials and different stacks of wood according to their different drying process requirements.

Description

technical field [0001] The invention relates to an auxiliary device for drying wood, in particular to an improved air supply device in the drying room for hot air. Background technique [0002] Drying operation is an indispensable production link in many fields of the national economy, especially the most energy-consuming but indispensable link in processing industries such as wood, medicine, food, chemical products, and agricultural and sideline products. [0003] Wood drying room is the main equipment for wood products processing. In China, 80% of the wood is dried in conventional drying room. Therefore, effectively improving the drying efficiency of wood drying room is a method that is both environmentally friendly and can increase the added value of products. The drying room is a rectangular house structure, long planks and strips of wood are stacked horizontally layer by layer, and the heated air is blown out horizontally by an axial flow fan at the top, blocked at the ...

AI Technical Summary

Problems solved by technology

[0006] 1. The four-bar linkage mechanism is fixed. It cannot adjust and change the speed and angle of each fan's steering, and cannot meet the requirements of different hot air supply for different stacked wood occasions. In this case, it will greatly affect the production progress and wood. The drying speed and quality of the material

[0007] 2. In the process of rack and pinion transmission, the drive motor shaft is docked with its own shaft on a fan as the driving shaft, and then the force is transmitted to multiple fans that rotate synchronously. If the driving force and transmission are too large, it is easy to cause the drive shaft to break and be damaged. Such transmission is also prone to mechanism jamming. With the increase of the number of fans, such a structure is more difficult to handle, which will affect the working efficiency and service life of the drying room
