Description
Technical Field
The invention belongs to the technical field of wood chip drying, and particularly relates to a wood chip drying machine with a good drying effect.
Background
When the wood chips are used for manufacturing various products, such as pressing into wood sticks and the like, the wood chips need to be dried firstly, so that the water content of the wood chips is reduced to a required range, and then the next manufacturing procedure can be carried out. For the drying of the wood chips, the most original method is to adopt natural drying, the wood chips are placed in the outdoor sunlight for natural airing, and the water in the wood chips is evaporated; although the natural drying has low cost and is simpler to operate, the natural drying takes long time and needs a large-area airing field; therefore, the wood chip drying machine is greatly influenced by natural conditions, has poor stability, and the quantity of the wood chips dried each time is not large, so that the requirements of large-scale production and processing cannot be met.
The Chinese patent CN104197651A discloses a sawdust dryer, which comprises a horizontal heat-insulating cylinder fixedly mounted on a frame, wherein a rotating shaft with more than two scraper-type stirrers uniformly distributed in the axial direction is arranged in the heat-insulating cylinder, and the rotating shaft is connected with a power transmission mechanism arranged outside the heat-insulating cylinder through one end of the rotating shaft; a feed hopper communicated with the inner cavity of the heat-insulating cylinder is arranged at the upper part of one end side of the heat-insulating cylinder, and a discharge hole with a switch plate is arranged below the end surface of the other end of the heat-insulating cylinder; the heat-insulating cylinder body is a double-layer cylinder body with a hollow middle part, and heating steam is introduced into the middle of the double-layer cylinder body or a steam heating coil is arranged in the double-layer cylinder body; the scraper type stirrer consists of at least three scraper blades uniformly distributed on a rotating shaft, more than five scraper type stirrers are uniformly distributed on the rotating shaft in the axial direction, and an exhaust port communicated with the inner cavity of the heat-insulating cylinder is arranged above the other end side of the heat-insulating cylinder opposite to the feed hopper; the device has the characteristics of simple structure, safe and convenient use, large drying amount, high drying speed, capability of continuously preparing the dried wood chips to meet the requirement and the like; the sawdust added into the dryer needs quantitative control, dust in the dryer with too much sawdust is too much, dust accidents are easily caused, the sawdust affects the working efficiency of the dryer too little, and the utilization of the dryer cannot be maximized.
