Abstract
The invention discloses a wood chip drying machine. The wood chip drying machine comprises a roller device. The roller device comprises a front-end roller and a rear-end roller; the front-end roller is connected to one end of the rear-end roller in a sleeving mode; the front-end roller is fixedly connected with the rear-end roller; the interior of the front-end roller comprises a separating mechanism for separating hot air and wood chips and a ventilation pipe allowing the hot air to enter; the ventilation pipe is located at one end of the separating mechanism; and the roller device is split into the front-end roller and the rear-end roller, and therefore the problem that in the conveying process of the wood chip drying machine, the rollers are too large, and consequently conveying is inconvenient is solved. The hot air and the wood chips are separated through the separating mechanism, and therefore the wood chips are not in direct contact with the hot air and are in contact with the pipe wall of the separating mechanism; and due to the fact that the pipe wall has the energy storage effect better than that of the hot air, the hot air required for processing the wood chips with the same number is reduced.
Description
Technical field
The present invention relates to wood chip drying technology field, be specifically related to a kind of dryer of drying for wood chip.
Background technology
Existing special wood chip drying plant adopts physical mechanical equipment usually, but there is no unified standard for wood chip drying plant at present.The patent No. is the Chinese invention patent of 201120429506.6, discloses a kind of wood dust dryer, carries out drying and processing by cylinder to wood chip.Be characterized in, cylinder is the container of wood chip and the oven dry place of wood chip, and hot gas enters drums inside by cylinder one end, carries out directly or indirectly drying and processing to the wood chip in cylinder.In this drying course, because temperature when hot gas inputs reaches 800 degree nearly, and wood chip is that temperature only has twenties degree in input cylinder, and the temperature difference is between the two very large, and both are when carrying out heat exchange, and thermal effect is lower frequently, causes the waste of heat energy.The temperature of wood chip in cylinder higher than 400 degree, not so must not easily cause wood chip redization phenomenon simultaneously, and therefore, the cylinder of wood chip drying plant is generally long, causes transport in actual shipment process inconvenient.
Summary of the invention
For solving the problems of the technologies described above, we have proposed a kind of wood dust dryer, its objective is and provide a kind of convenient transportation and the higher frequently wood dust dryer of thermal effect.
For achieving the above object, technical scheme of the present invention is as follows:
Wood dust dryer, comprises drum apparatus, and described drum apparatus comprises front end cylinder and rear end cylinder, and described front end drum sleeve is connected to cylinder one end, described rear end, and described front end cylinder is fixedly connected with described rear end cylinder; The breather pipe that described front end drums inside includes the partition for separating hot gas and wood chip and enters for hot gas, described breather pipe is positioned at described partition one end.
Preferably, described partition comprises pair of discs and pipeline, and described install pipeline is in described in a pair between disk, and described pipeline is through described disk.
Preferably, described pipeline is at least two, and one, described pipeline is arranged at described disc centre position, and install pipeline described in all the other is in described disk border position.
Preferably, the cross-sectional area being positioned at the described pipeline of described disc centre position is greater than the cross-sectional area of the described pipeline being positioned at described disk border position.
Preferably, the cross-sectional area being positioned at the described pipeline of described disk border position is identical.
Preferably, be positioned at the described pipeline center location rule of described disk border position to be distributed in disc centre be the circumferentially same of benchmark.
Preferably, described front end cylinder and described rear end cylinder pass through Flange joint.
Preferably, described drum apparatus inwall is provided with heat-insulation layer.
Preferably, the thickness being positioned at the described heat-insulation layer of described breather pipe upper end is greater than the thickness of the described heat-insulation layer being positioned at described other positions of drum apparatus.
Preferably, described wood dust dryer is provided with three and accepts circle, six undertaking wheels and support, described undertaking circle is arranged on described drum apparatus, described undertaking wheel is arranged on described support, accept circle for one to accept to take turns to coordinate to form accept assembly with two, described three lay respectively at the rear and front end of drum apparatus and the intersection of front end cylinder and rear end cylinder to accepting assembly.
Pass through technique scheme, the beneficial effect that the present invention obtains is: by drum apparatus being divided into front end cylinder and rear end cylinder, and front end cylinder can be fixedly connected with rear end cylinder, thus solve the transport inconvenience that wood dust dryer causes because cylinder is long; The utilization of partition, the incipient stage that wood chip is being dried can not directly be contacted with hot gas, but contact with the partition tube wall after heated by hot gas, though the temperature of tube wall is not as hot air temperature, but far away higher than the temperature of wood chip, it can not weaken the front-end processing of wood chip heating, and tube wall also serves the effect stored heat simultaneously.Because tube wall in the cylinder of front end is to the constraint of hot gas scope, make equivalent hot gas be transmitted to the heat of rear end cylinder more, like this hot blast rate that the wood chip of equivalent carries out needed for drying and processing is reduced, improve the utilization rate of the energy.
