Abstract

The invention discloses a biomass material drying machine, wherein a motor is connected onto a rotating shaft of a machine frame through a transmission mechanism; transmission wheels are symmetrically mounted at two ends of the rotating shaft; a pair of sealing heads are symmetrically fixed on rotating shaft extension lines at outer ends of the two transmission wheels on the machine frame; a roller is mounted between the two sealing heads in a rotating and sealed way; a spiral material guide plate is arranged on the circumferential inner wall of the roller; a material inlet communicated with the interior of the roller is formed above the outer end of the front sealing head; a material outlet communicated with the lower part inside the roller is formed at the outer end of the back sealing head; two rolling rings meshed with the transmission wheels respectively are arranged on the outer circle of the roller; a hot air tube is outwardly mounted in the center of the front sealing head; a heating tube is fixed on the hot air tube of the front sealing head along a central axis inside the roller; a moisture absorbing tube is mounted above the heating tube from the middle part to the back sealing head; and a branch heating tube is mounted under the heating tube. According to the invention, the hot air is in targeted contact with materials, so that the drying efficiency can be increased by two times and energy consumption and cost are greatly reduced.

Description

A kind of biomass material dryer

Technical field:

The present invention relates to drying equipment, particularly a kind of being applicable to carried out dry dryer to loose particles of living beings gas permeability such as herbage, stalk, leaf, wood shavings, corncobs.

Background technology:

Present biomass material dryer all is a plurality of poplar flitch to be installed in the cylinder of a sealing or the center arranges a shaft, and material is shed in the cylinder space, is separately installed with simultaneously warm-air pipe and the air-introduced machine that is communicated with cylinder at the two ends of cylinder.The dryer of this traditional structure, the major defect that exists is must carry out in the sealing situation because of whole drying course, and whole space will have certain temperature just can reach the effect of oven dry, but hot blast, material, water vapour mix in the whole space, and the excess Temperature in drum front end space easily catches fire, the rear end temperature is excessively low, and the material secondary is made moist.So power consumption is high, efficient is low, productivity effect is low.

Summary of the invention:

The purpose of this invention is to provide a kind of low, high biomass material dryer that can improve productivity effect of efficient that consumes energy.

Technical scheme of the present invention is finished as follows, a kind of biomass material dryer, it includes a frame, it is characterized in that: be horizontally installed with a rotating shaft a frame, be connected with a motor through transmission mechanism in the rotating shaft, be symmetrically installed with drive at the rotating shaft two ends, two drive outer end rotating shaft extended lines are symmetrically fixed with a pair of end socket on frame, between two end sockets, rotate sealing a cylinder is installed, circumferential inner wall at cylinder is provided with the spirality stock guide, above the front head outer end, be provided with one with cylinder in the charging aperture that is communicated with, the rear head outer end be provided with one with cylinder in below the discharging opening that is communicated with, be provided with two rolling rings that are meshed with drive respectively at the cylinder cylindrical, a warm-air pipe outwards is installed at the front head center, the warm-air pipe other end is connected with air-heater, air-heater is connected in the quench passage of a hot-blast stove, on the warm-air pipe of front head, be fixed with a heating tube along central axis in the cylinder, on heating tube, from the middle part to rear head a moisture absorption pipe is installed, outside rear head, lead to dehumidification tube in moisture absorption pipe rear end, the dehumidification tube tail end is connected with an air-introduced machine, is fixed with uniform multicomponent on the outer wall downwards and props up heating tube below heating tube.

A kind of biomass material dryer of the present invention is characterized in that: each group of branches heating tube has respectively at least two to be the fan-shaped below that laterally is installed in central heating tube.

The present invention makes between hot blast and the material and contacts targetedly, hot blast passes through warm-air pipe, material moves in cylinder bottom, water vapour moves on cylinder top, strengthened diabatic process, in no longer wind sheltering of charging discharging place, material is ceaselessly stirred and is flowed in cylinder bottom all the time, drying efficiency can improve twice, greatly reduces energy consumption and cost.

Description of drawings:

Fig. 1 is structural representation of the present invention; Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment:

Describe by reference to the accompanying drawings embodiment in detail, the present invention is horizontally installed with a rotating shaft 15 a frame 12, be connected with a motor 13 through transmission mechanism in the rotating shaft, be symmetrically installed with drive 11 at the rotating shaft two ends, two transmission outer end rotating shaft extended lines are symmetrically fixed with a pair of end socket 9 on frame, between two end sockets, rotate sealing a cylinder 8 is installed, circumferential inner wall at cylinder is provided with spirality stock guide 6, above the front head outer end, be provided with one with cylinder in the charging aperture 4 that is communicated with, the rear head outer end be provided with one with cylinder in below the discharging opening 17 that is communicated with, be provided with two rolling rings that are meshed with drive respectively 5 at the cylinder cylindrical, a warm-air pipe 3 outwards is installed at the front head center, the warm-air pipe other end is connected with air-heater 2, air-heater is connected in the quench passage 1 of a hot-blast stove, on the warm-air pipe of front head, be fixed with a heating tube 16 along central axis in the cylinder, on connect heat pipe, from the middle part to rear head a moisture absorption pipe 7 is installed, outside rear head, lead to dehumidification tube 10 in moisture absorption pipe rear end, the dehumidification tube tail end is connected with an air-introduced machine 18, is fixed with uniform multicomponent on the outer wall downwards and props up heating tube 14 below heating tube.Each group of branches heating tube has respectively at least two to be the fan-shaped below that laterally is installed in heating tube.When drying cutting up with a hay cutter broken biomass material, by the material blowing hot-air oven dry of each group of branches heating tube to the cylinder inner bottom part, while is ceaselessly stirred along the spirality stock guide on the inner wall of rotary drum and advances, material is all dried under by the high humidity gas shock in cylinder bottom to discharging cylinder from entering cylinder, vapours is drawn through air-introduced machine by the moisture absorption pipe of top in the cylinder, has overcome the defective of prior art.
