Heating and blowing device for large hot air drying room

Abstract

The invention relates to timbers, pharmaceuticals, foods and chemical products, in particular to a heating and blowing device for a large hot air drying room. A plurality of fans (1) are disposed in a rectangular fan support frame (12). Gaps among the fans (1) are blocked by air blocking plates (13). The fans are linked by a synchronization rotation linkage mechanism (2) for synchronous horizontal rotation. The fan support frame (12) is fixed on a rectangular movable frame (17). Rollers (19) embedded into guide rails (18) on two sides are disposed on two sides of the fan support frame (12). An air guide component (4) is disposed on a blowing side of each fan (1). A plurality of radiators (6) corresponding to the fans (1) are disposed at two ends of the guide rails. Three arc flow deflectors (11) are disposed at three inner included angles of the drying room. By the heating and blowing device, power consumption is lowered greatly, operation cost and drying cost are lowered, the drying room is enabled to be efficient, energy-saving and widely applicable, timbers of two or more different kinds or of different thicknesses can be evenly dried simultaneously, production efficiency is increased, and drying operations are highly flexible.

Description

technical field [0001] The invention relates to the field of drying wood, medicine, food, chemical products, agricultural by-products and other materials, in particular to a heating and air supply device suitable for various large-scale hot air drying rooms. Background technique [0002] Drying operation is an indispensable production link in many fields of the national economy, and it is also the most energy-consuming but indispensable link in the processing industries such as wood, pharmaceuticals, food, chemical products, agricultural and sideline products, etc. The hot air drying room is an important part of drying operations. Equipment, the hot air circulation system in the drying room is the key to improving the efficiency of the drying room, saving energy, and ensuring product quality. The technological innovation of drying equipment has a significant impact on enterprises. According to the technical requirements of drying different materials, there must be an air flo...

Problems solved by technology

[0005] Although this method can achieve the purpose of uniform drying, after many years of operation, the inventor feels that the program is still lacking. With the difference of drying objects and the special requirements of users, the original mechanism can not meet the needs.

In summary, there are the following defects: 1. Since the heating air is uniformly output and circulated evenly, the requirements for the dried wood are relatively high, such as: a 100M 3 The wood to be dried each time in the drying room must be the same tree species, the same thickness specification, and the same initial moisture content, in order to make 100M 3 The wood is evenly dried under a specific drying process; 2. A 100M 3 The volume of dry wood required to be loaded in the drying room is 100M 3 , too much can't fit, and less can't, when the volume of the wood to be dried is less than 100M 3 When it is not enough to fill the drying room, the circulating air in the drying room will produce a local short circuit, which will affect the uniformity of wood drying, so it is necessary to wait for the accumulated volume of wood to be dried to reach 100M 3 It can only enter the drying room to complete uniform drying, which prolongs the production cycle, reduces production efficiency, affects the timely delivery of orders by enterprises, and has a negative impact on drying quality and drying cost.
