Description
Technical field
The present invention relates to a kind of drying tunnel hot air circulating system.
Background technology
Present tunnel type, box drying plant be general to be existed drying plant to dry remaining heat energy not to be fully utilized, or has and utilize but the layout in air channel is not exclusively reasonable, cause the inner oven dry in baking district inhomogeneous, and power consumption is large.
Summary of the invention
The invention provides a kind of drying tunnel hot air circulating system, the inner oven dry of its baking zone is even, thus the energy consumption of greatly reducing.
The present invention has adopted following technical scheme: a kind of drying tunnel hot air circulating system, described bellows, bottom at bellows is provided with support, inwall at bellows is provided with thermal insulation layer, be set to the baking district in bellows inside, above and below in the baking district is respectively equipped with bellows wind deflector and lower circulated air frame, between bellows wind deflector and lower circulated air frame, be provided with tube rack, tube rack is positioned at the baking district, tube rack is installed on the inwall of bellows, at tube rack fluorescent tube is installed, be connected with backwind tube at the bellows wind deflector, be connected with the return air distributing pipe in the side of backwind tube, the return air distributing pipe is communicated with backwind tube, bottom at the return air distributing pipe is provided with bend pipe, be provided with the waste discharge connector at bend pipe, be connected with the waste discharge cylinder in the side of waste discharge connector, be provided with the cylinder thermal insulation board between waste discharge cylinder and the waste discharge connector, be provided with valve at the waste discharge cylinder, be connected with blast pipe at lower circulated air frame, the return air distributing pipe is positioned at the blast pipe below, is provided with centrifugal blower between return air distributing pipe and blast pipe, centrifugal blower is connected with blast pipe, and centrifugal blower is relative with the return air distributing pipe.
Described return air distributing pipe is distributed with the wind hole, and centrifugal blower is relative with the wind hole on the return air distributing pipe.Described centrifugal blower is set to multi-wing centrifugal fan.Described valve is set to the waste discharge gate valve.Described valve is set to manual adjusting valve.
The present invention has following beneficial effect: the present invention is baking district residue heat energy, by reusing in the input of the wind aperture multi-wing centrifugal fan above the return air distributing pipe bellows, can save the energy like this.The circulated air frame is to do framework with section bar under the present invention, be connected with blast pipe at lower circulated air frame, make so the inner reasonable unobstructed air draft structure that forms, the return air distributing pipe is distributed with the wind hole, centrifugal blower is relative with the wind hole on the return air distributing pipe, residue heat energy, can be dried evenly baking zone inside in the baking district in wind deflector enters wind pushing box like this by centrifugal blower and backwind tube, greatly reduce energy consumption.
