Abstract

The utility model discloses a powder drying plant, consisting of a base, a baking barrel, a hopper, a waste heat recycling pipe, a transmission pipe, a material discharge blower, an efferent and a material storage tank, wherein, the baking cavity of the baking barrel is provided with a threaded spiral powder baking pipe; the bottom end of the powder baking pipe is connected with the hopper via a feed pipe, while the top end of the powder baking pipe is connected with the transmission pipe; the feed pipe is connected with a chimney via the waste heat recycling pipe; the interior of the baking cavity is also provided with a threaded spiral secondary powder baking pipe, wherein, the bottom end of the secondary powder baking pipe is connected with the transmission pipe via the feed pipe, a material storage bucket, a circulating tube and a circulating fan; the top end of the secondary powder baking pipe is communicated with the material discharge blower via a material discharge nozzle. The utility model has the advantages that the phenomenon of powder siltation in the pipe is avoided, the degree of power drying is even, and the utility model has positive effects in improving the quality of bamboo charcoal stick.

Description

The powder drying plant

Technical field

The utility model relates to a kind of oven, specifically, is a kind of powder drying plant.

Background technology

Before producing bamboo wood powder carbon rod, it is that the bamboo wood powder is dried that procedure is arranged, existing powder drying plant, have the spiral powder baking pipeline of multi-turn of a screw-like in the baking chamber of baking bucket, its weak point is, because the powder of the multi-turn of spiraling baking duct length is long, cause the bamboo wood powder that the phenomenon of delay is arranged in pipeline, the powder for drying degree is inhomogeneous, and the bamboo wood powder carbon rod of production produces distortion, and is of poor quality.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of powder of stopping at ducted trapping phenomena, and it is even to reach the powder for drying degree, to improving the powder drying plant that bamboo wood powder carbon rod quality has good effect.

The technical scheme of the utility model powder drying plant, comprise pedestal, the baking bucket, loading hopper, the residual heat recovery pipe, conveyance conduit, the discharging air blast, efferent duct and storage tank, has the powder baking pipeline that a screw-like is spiraled in the baking chamber of baking bucket, the lower end of powder baking pipeline is connecting loading hopper by feed pipe, the upper end of powder baking pipeline is connecting conveyance conduit, feed pipe is communicated with chimney by the residual heat recovery pipe, also be provided with the secondary powder baking pipeline that a screw-like is spiraled in the described baking chamber, secondary feed pipe is passed through in the lower end of described secondary powder baking pipeline, hold charging basket, circulation pipe, recycle gas blower is connected with conveyance conduit, and the upper end of described secondary powder baking pipeline is communicated with the discharging air blast by discharge nozzle.Described secondary feed pipe is communicated with the baking chamber by hot reuse pipe.

The beneficial effect of the utility model powder drying plant is, can stop powder at ducted trapping phenomena, and it is even to reach the powder for drying degree, has positive effect to improving bamboo wood powder carbon rod quality.
