Wood chip drying machine with good drying effect

Abstract

The invention discloses a wood chip drying machine with a good drying effect. The wood chip drying machine comprises a processing box and a feeding pipe arranged at the top of the processing box. A drying cavity is formed in the processing box, a feeding hole matched with the feeding pipe is formed in the top of the drying cavity, a feeding hopper is arranged at the top of the feeding pipe, a discharging opening is formed in one side of the drying cavity, a first cover plate is movably connected to the inner wall of the discharging opening, a first mounting plate is arranged in the feeding pipe, a first mounting groove is formed in the bottom of the first mounting plate, a second cover plate is movably connected into the first mounting groove, the second cover plate divides the feeding pipe into a first cavity and a second cavity, and a second mounting plate is arranged on the inner wall of the second cavity. Wood chips added into the drying cavity each time are quantitatively controlled through the second cavity, utilization of the drying cavity is maximized, and potential safety hazards caused by excess adding of the wood chips in the drying cavity are prevented.

Description

technical field [0001] The invention belongs to the technical field of sawdust drying, in particular to a sawdust dryer with good drying effect. Background technique [0002] When using wood chips to make various products, such as pressing into wooden sticks, etc., it is necessary to dry the wood chips first to reduce the moisture content to the required range before proceeding to the next step of the production process. For the drying of wood chips, the most primitive method is to use natural drying, put the wood chips in the outdoor sun for natural drying, and evaporate the moisture in the wood chips; although this kind of natural drying is low in cost and relatively simple to operate, natural drying It takes a long time and requires a large area of ​​drying space; therefore, it is greatly affected by natural conditions, has poor stability, and the amount of sawdust dried each time is not large, which cannot meet the needs of large-scale production and processing.

For the drying of wood chips, the most primitive method is to use natural drying, put the wood chips in the outdoor sun for natural drying, and evaporate the moisture in the wood chips; although this kind of natural drying is low in cost and relatively simple to operate, natural drying It takes a long time and requires a large area of ​​drying space; therefore, it is greatly affected by natural conditions and has poor stability, and the amount of sawdust dried each time is not large, which cannot meet the needs of large-scale production and processing

[0003] Chinese patent CN104197651A discloses a sawdust dryer, which includes a horizontal heat preservation cylinder fixedly installed on the frame, and a rotating shaft with more than two scraper-type agitators evenly distributed in the axial direction is arranged in the heat preservation cylinder. And the rotating shaft is connected to the power transmission mechanism installed outside the heat preservation cylinder through one end; the upper part of one end side of the heat preservation cylinder is provided with a feed hopper connected to the inner cavity of the cylinder, and the other end of the heat preservation cylinder is provided with a belt below the end face. The discharge port of the switch plate; the heat preservation cylinder is a hollow double-layer cylinder in the middle, and heating steam is passed into the middle of the double-layer cylinder or a steam heating coil is built in; the scraper type agitator is composed of Composed of at least three scrapers evenly distributed on the rotating shaft, more than five scraper-type agitators are evenly distributed axially on the rotating shaft, and the insulating cylinder is provided with a It is connected to the exhaust port of the inner cavity of the heat preservation cylinder; it has the characteristics of simple structure, safe and convenient use, large drying capacity, fast drying speed, and can continuously produce and dry wood chips to meet the needs; it needs to be added to the dryer for wood chips Quantitative control, too much dust in the dryer will easily cause dust accidents, too little sawdust will affect the efficiency of the dryer, and the utilization of the dryer cannot be maximized
