Connect radiator, radiator upper end, which is provided with the downside of wind-supplying mouth, torus, is provided with circulating fan, circulating fan be connected to averaging wind pipe,
Lower averaging wind pipe.
The drying body includes 2-5 drying unit, and each drying unit is arranged in a linear, and each drying unit is equal
Using blowing hot-air device up and down and it is symmetrical arrange mode, material is blown uniform, finished product materials drying is uniform.
One end of the conveying link network, which is provided with drive roll, drive roll, to be connected with driving motor, conveys the other end of link network
Provided with driven voller, drive roll, driven voller are rack-mount by fixed seat, and supporting carrier roller, support are provided with the middle part of conveying link network
Carrying roller ensures that conveying link network is horizontally set between averaging wind pipe and lower averaging wind pipe.
Compared with prior art, the beneficial effects of the utility model are:The utility model is simple in construction, generally by metal plate
Part and shaped steel are constituted, and manufacturing cost is low;Natural gas is high, pollution-free as fuel heat;Natural gas after burning passes through radiator
It is converted into hot blast and is blown into equipment drying nut material, it is ensured that the nut after drying reaches the effect of high-quality;This equipment is set
Meter causes low energy loss, efficiency high, material to be heated evenly and best in quality;The features such as installing, debug and be easy to maintenance.

Embodiment
In order that of the present utility model realize that technological means, creation characteristic, reached purpose and effect are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figures 1 to 3, a kind of top and bottom blowing natural gas direct combustion type individual layer mesh belt dryer, including:Drying body 3, dries
One end of dry body 3 is provided with feeding device, and feeding device is arranged on support 2, and feed hopper 1 is provided with feeding device, is fed
Material is sent in drying body 3 by 1 lower end of struggling against by conveyer belt, provided with conveying link network 11, the dryer in drying body 3
Be divided into drying cavity, torus in body 3, drying cavity, torus connection are set, be placed with the downside of drying cavity averaging wind pipe 10, it is lower
Airduct 12, the upper downside of averaging wind pipe 10 is provided with the upside of air outlet, drying cavity provided with air outlet, the upside of lower averaging wind pipe 12 and is provided with moisture exhausting port
5, moisture exhausting port 5 is connected on the upside of wet-emitting blower 7, torus by dehumidification tube 6 and is provided with burner 8, the connection radiating of the one end of burner 8
Device 4, the upper end of radiator 4, which is provided with the downside of wind-supplying mouth 9, torus, is provided with circulating fan 13, and circulating fan 13 is connected to averaging wind pipe
10th, lower averaging wind pipe 12.
The drying body 3 includes 2-5 drying unit, and each drying unit is arranged in a linear, and each drying unit
Using blowing hot-air device up and down and it is symmetrical arrange mode, material is blown uniform, finished product materials drying is uniform.
One end of the conveying link network 11, which is provided with drive roll, drive roll, to be connected with driving motor 14, conveys link network 11
The other end is provided with driven voller, and drive roll, driven voller are arranged on support 2 by fixed seat, and the middle part of conveying link network 11 is provided with support

Operation principle of the present utility model is:
Dryer operationally, carries out feeding at feed hopper, and feed hopper makes material be evenly scattered on guipure, is formed
Certain thickness material bed, guipure provides kinetic energy by motor.This equipment is, as fuel, to be carried by burner apparatus by natural gas
Heating load, by heat sink arrangement, heat sink arrangement upper end is equipped with air compensation device, and the cold air heating outside casing dissipates simultaneously
Mixing hot blast after the circulating fan of the vertical lower end of hot device changes the heat that burner is provided by radiator is conveyed to material,
The mixing hot blast of this cleaning is soft hot blast, can effectively protect the epidermis of material and play the effect of material drying.With
Hot blast at the air outlet of circulating fan, is divided at two by this equipped with split-wind plate simultaneously, and material is supplied by upper averaging wind pipe at one
Heat, another place by lower averaging wind pipe to material heat supply, two averaging wind pipes work simultaneously, reach above and below blowing hot-air effect so that thing
Material is heated evenly, best in quality.Air port is left in box house design, it is by the hot air circulation in body feed tank body to burner box
In vivo, recycling for heat is reached, the loss of heat is reduced.In addition, being equipped with wet-emitting blower, wet-emitting blower in the upper end of frame
The wet gas in casing is excluded outside casing by hydrofuge airduct, drying efficiency is improved.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
