Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

In a typical embodiment of the present invention, as shown in fig. 1, a novel hot air drying oven is provided, which comprises a drying oven body 2, a drying cavity 8 is arranged in the drying oven body 2, a plurality of chain plates 7 are installed in the drying cavity 8, and the chain plates 7 are staggered up and down; the outer layer of the drying cavity 8 is an air supply layer 5, a plurality of air supply holes are arranged in the air supply layer 5, and hot air is conveyed into the drying cavity 8; the outer layer of the air supply layer 5 is a heat insulation layer 3.

A plurality of link joints 7 of internally mounted of stoving chamber 8, link joint 7 is crisscross the setting from top to bottom in stoving chamber 8, motor 1 is as the power supply of link joint 7, the motion opposite direction of two adjacent link joints, if, when the quantity of link joint is 3, upper link joint transports right under the drive of motor, because continuous link joint is crisscross the setting, material on the upper link joint can drop on the middle level link joint, the middle level link joint moves left after that, material on the middle level link joint drops on the link joint of lower floor, through the motion of material in the drying process, the upset, drying efficiency has been improved, the fortune material speed of link joint can also be controlled through the motor.

The upper portion of drying furnace body 1 sets up pan feeding mouth 4, installs directional batcher 6 on the pan feeding mouth 4, through directional batcher to drying chamber 8 in the transported substance material, directional batcher is screw feeder, through screw feeder control feed volume and feed speed, and current structure can be adopted to concrete structure.

The outside in stoving chamber 8 sets up air supply layer 5, sets up a plurality of supply-air holes on the air supply layer 5 for to the stoving intracavity delivery hot-blast, even in order to guarantee that the air supply, the supply-air hole is evenly arranged, and the mode of arranging of supply-air hole can be rectangle, circular or rhombus, also can be for other modes of laying, as long as can guarantee that the air supply is even can.

The outside of layer 5 that send wind is heat preservation 3, the air intake setting of drying furnace body is in the bottom of heat preservation, the air intake passes through defeated tuber pipe and links to each other with gas furnace 10, hot-blast air that heats through gas furnace enters into the cavity between heat preservation and the air supply layer through the air intake of heat preservation like this, then dry the material in getting into the stoving chamber through the supply-air outlet on the air supply layer, the heat preservation adopts the cotton felt of aluminium silicate, can be able to bear 650 ℃ of high temperature, can effectively reduce the heat loss among the hot-blast transportation process, drying efficiency has been improved.

The gas furnace 10 is provided with an air inlet below, air is sent to the gas furnace through a centrifugal fan or an axial flow fan, the gas furnace is different from the existing gas furnace in that basalt stone particles 11 are added into the gas furnace 10, the basalt stone particles can enable air in the gas furnace to be heated uniformly, and in addition, the adopted basalt stone particles can resist high temperature and cannot be decomposed or generate other substances when being heated.

Still be provided with the exhaust pipe at the top of drying furnace body, the warm braw after will drying is discharged, because the warm braw of exhaust still has certain temperature, but humidity can be than higher, can send into the gas furnace again after dehumidifying warm braw at this moment and heat, has realized hot-blast cyclic utilization.

The side bottom of drying furnace body sets up the discharge gate, and the material on the link joint of bottom falls on the conveyer belt, sends into the collecting tank through the discharge gate with the material.

When the drying furnace works:

the work flow of material does, and the material in the storage pond passes through the pan feeding mouth through screw feeder and gets into the stoving chamber, drops on the link joint, and the material overturns through the transport of multilayer link joint, utilizes the hot-blast material that the venthole sent to fully dry to the material, and the material after the stoving is carried to the conveyer belt that the discharge gate goes out through the link joint of bottommost layer, sends into the material in the collecting tank.

The working flow of the air is that the air is sent into the gas furnace under the action of a centrifugal fan or an axial flow fan, is uniformly heated under the action of basalt stones in the gas furnace, then enters a cavity between the heat preservation layer and the air inlet layer through the air conveying pipe and the air inlet on the heat preservation layer, and then enters the drying cavity through the air supply hole to dry materials in the drying cavity. The temperature of the dried hot air is reduced, the moisture in the materials is taken away, the air is discharged through the exhaust pipe, the discharged air can be dehumidified through the dehumidifier and then is sent into the gas furnace for heating, and the hot air recycling is realized.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
