Abstract

The utility model relates to a hot-blast pipe drying device, comprising a drying, device box body, an air inlet, a fan, an exhaust opening, etc. One side of the box body is provided with a hot air chamber, multilayer hot air pipes are distributed in the drying chamber on the central position of the box body, each layer is provided with an array of hot air pipes which are in parallel arranged. The side wall of the drying chamber is provided with an intercalation, which composes an air back streaming cavity communicated with the exhaust opening. Air flow is flown into the drying chamber from a hot air chamber via the air holes of the hot air pipes, moisture which is generated because of drying is exhausted out towards the exhaust opening from the back streaming cavity. The utility model can carry out even drying towards material, having the advantages of simple and reasonable structure, reliable operation, and low energy consumption. The utility model is especially suitable for the drying operation of materials such as tea, Chinese medical materials, etc.

Description

A kind of warm-air pipe drying device

The utility model relates to a kind of equipment with the heated-air drying material.

Existing hot blast dry materials equipment, majority directly is blown into hot-air the material surface with blower fan, this direct-firing heat energy send mode, it is variant to cause each position of material to be heated, and aridity is inhomogeneous.

The purpose of this utility model proposes a kind of hot air type drying device of new structure.Blow uneven problem to solve the heat energy that existing heated-air drying equipment exists.

Structure of the present utility model, comprise the drying device casing, air inlet, blower fan, electric calorifie installation and exhaust outlet etc., a side that is casing is provided with a hot gas chamber, in the hothouse in casing centre, divide multilayer to lay warm-air pipe, each interlayer is provided with the charging tray support, every layer has the parallel Boulez of a heat extraction airduct, said warm-air pipe is fixed on the partition wall between hot gas chamber and the hothouse and with the hot gas chamber by the spliced eye seat and communicates, warm-air pipe has a plurality of wind hole along tube wall, casing also has a sidewall to have the gas backstreaming chamber that the interlayer formation communicates with exhaust outlet at least, and the partition wall between this back cavity and the hothouse is provided with passage.

Wind pore size distribution on the said warm-air pipe is in second disc of hot blast tube wall.

The dorsal part of drying device casing is located in said hot gas chamber, and said gas backstreaming chamber is located at the left and right sides of casing.

Blower fan of the present utility model and electric calorifie installation are built in the casing, blower fan is advertised facing to electric calorifie installation, the electric calorifie installation heated hot air heated is blasted the hot gas chamber, and the hot blast in the hot blast chamber is that the wind hole of Boulez is blown into each floor of hothouse on the warm-air pipe tube wall through being distributed in each floor of hothouse, can form uniform air-supply, so that the material that is positioned in each layered material dish is carried out even drying, after hot blast was passed to material with heat energy, the moisture of formation was directly discharged from exhaust outlet through the passage inflow back cavity of sidewall.Simple and reasonable, reliable, energy consumption is low, is adapted to the drying operation of materials such as tealeaves, Chinese medicine especially.

Below be drawing explanation of the present utility model:

Fig. 1 is that the utility model is along blower fan position G-G longitudinal sectional view;

Fig. 2 is that the utility model is along exhaust outlet position B-B longitudinal sectional view;

Fig. 3 be the utility model along level to the A-A cutaway view.

Be described in further detail below in conjunction with the concrete structure of accompanying drawing the utility model embodiment:

As Figure 1-3, this dry device is square, the 1st, blower fan, be installed in these dry device box 12 tops by near the hot gas chamber 3, the blower fan top is an air inlet 10, it behind the air port of blower fan electric heating body 2,3 is the hot gas chamber, rear wall (partition wall between instant heating air chamber and the hothouse) 9 by wall behind the casing and hothouse 14 constitutes, lay multilayer warm-air pipe 5 in the hothouse 14, the warm-air pipe stock is fixed on the hot gas outlet spliced eye seat 4, warm-air pipe is a light-wall pipe, second disc of its tube wall has a plurality of wind hole 15, the left and right sides of casing is provided with gas backstreaming chamber 7, and the partition wall of this back cavity and hothouse 14 (being the sidewall of hothouse) 6 has a plurality of gas backstreaming passages 16, is provided with charging tray support 13 in the two side 6 of hothouse, hold the material disc 11 of dried material in order to supporting, the wet steam that dry materials produces is discharged through exhaust outlet 8 by passage 16 inflow gas back cavities 7.The flow direction of the arrow indication air-flow among each figure.

Use the tea-leaf withering machine of the utility model design design, be aided with temperature controller, the device of time controller can be realized curing refining tealeaves automatically, meets the requirements of quality index.
