Description

Gravity drying machine

Technical field

The utility model relates to a kind of gravity drying unit of non-sticky material.

Background technology

All there is bigger defective in existing drying unit in varying degrees, rotating drum type drying machine energy consumption height, and dust is bigger, and environmental issue should not solve, and rate of heat exchange is lower, the running expense height.Tower drier, the device interior thermal deformation is serious, and the equipment life cycle is short, maintenance duration expense height.

Summary of the invention

In order to overcome the shortcoming of prior art, the invention provides a kind of gravity drying machine of non-sticky material, it is simple in structure, reduced investment, emission compliance, running expense is low, and the thermal efficiency is higher, safeguards that simply, the device life cycle is long.

The technical scheme that the utility model technical solution problem is taked is: vertical pan feeding elevator is fixed on the ground, the upper end communicates with the feed bin sealing by the pan feeding scraper-trough conveyer, the lower end sealing and fixing drying cylinder body of feed bin, uniform steam vent on the sidewall of drying cylinder body, fixing gas collection collet on the inwall of the drying cylinder body at steam vent place, the bottom of drying cylinder body and body supporting seat are fixed, fixing with one heart heat radiation aeration tower in the drying cylinder body, the heat radiation aeration tower is built into the tower shape by laying bricks or stones with nonmetal refractory block, uniform passage on its sidewall, its inner chamber is hot smoke chamber, its inner bottom part combuster, its top is the sub-material cone fixedly, toroidal cavity between drying cylinder body and the heat radiation aeration tower is the drying materials road, there is discharging awl bucket the lower end in drying materials road, there is the heat-resisting belt conveyor of speed governing the lower end of discharging awl bucket, drying cylinder body is penetrated with 4-6 air inducing flue from top to bottom, the upper end of air inducing flue is air-introduced machine fixedly, described body supporting seat is fixed on the ground, air admission hole is arranged on it, and air admission hole communicates with described combustion chamber.

Because initial hot flue gas is material bed through continuous motion, take away the moisture in the material, dust that produces during fired coal combustion and black smoke are through the filtration of the slow mobile bed of material, and hot flue gas is among whole heat exchanging process converts moisture discharge and atmosphere to, need not increase dust collection device, get final product qualified discharge.The heat radiation aeration tower adopts nonmetal refractory block to build by laying bricks or stones, puts and the burner hearth top, does not produce distortion under the high temperature, thereby makes whole dryer life cycle long, safeguards simple.Drying course relies on the effect with the material deadweight, material is slowly moved finish drying course, need not power, saved the energy.Adopt the design of built-in combustion chamber for reducing this drying unit of floor space.It is simple to make this drying unit possess technology, reduced investment, energy consumption is low, thermal efficiency height is energy-conservation, environmental protection, take up an area of few, advantage such as running expense is low.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a schematic front view of the present invention.

Fig. 2 is A place enlarged drawing among Fig. 1 of the present invention.

The specific embodiment

Shown in 1,2, vertical pan feeding elevator 1 is fixed on the ground, the upper end communicates with feed bin 3 sealings by pan feeding scraper-trough conveyer 2, the lower end sealing and fixing drying cylinder body 4 of feed bin 3, uniform steam vent 9 on the sidewall of drying cylinder body 4, fixing gas collection collet 12 on the inwall of the drying cylinder body 4 at steam vent 9 places, the bottom of drying cylinder body 4 and body supporting seat 14 are fixing.Fixing with one heart heat radiation aeration tower 7 in the drying cylinder body 4, the tower shape is built in the nonmetal refractory block 10 of heat radiation aeration tower 7 usefulness by laying bricks or stones, uniform passage 11 on its sidewall, its inner chamber 18 is hot smoke chamber, its inner bottom part combuster 13, its top is the sub-material cone fixedly.Toroidal cavity between drying cylinder body 4 and the heat radiation aeration tower 7 is drying materials road 19, and there is discharging awl bucket 16 lower end in drying materials road 19, and there is the heat-resisting belt conveyor 17 of speed governing the lower end of discharging awl bucket 16.Drying cylinder body 4 is penetrated with 4-6 air inducing flue 8 from top to bottom, and the upper end of air inducing flue 8 is air-introduced machine 5 fixedly.Described body supporting seat 14 is fixed on the ground, and air admission hole 15 is arranged on it, and air admission hole 15 communicates with described combustion chamber 13.Passage 11 outlets in the described nonmetal refractory block 10 downwards.

Need the oven dry material to promote, in pan feeding scraper-trough conveyer 2 is delivered to drying cylinder body 4 top feed bins 3 by pan feeding elevator 1.Under the effect that places heat radiation aeration tower 7 top sub-material cones 6, the material of required oven dry is uniformly distributed in the drying materials road 19 of heat radiation aeration tower periphery, and material slowly moves from top to bottom along drying materials road 19 under the effect of self gravitation.Coal-fired the burning back produces heat by manually being added into built-in combustion chamber 13, and cold air enters via the air admission hole 15 around the body supporting seat 14, passes the combustion chamber, forms hot flue gas.Hot flue gas is under the effect of air-introduced machine 5, rise along the heat radiation aeration tower, discharge through the passage 11 that is distributed in nonmetal refractory block 10 combination of each layer of heat radiation aeration tower, hot flue gas relies on the special construction of trapezoidal building block, dispel the heat every layer of building block week of aeration tower downwards along every layer of venthole, form hot flue gas ring, hot flue gas is fully mixed with slow shift(ing) ring moulding mixture layer, the moisture on material surface and hot flue gas produce heat exchange, and filtering out coal dust in the hot flue gas, hot flue gas makes the water evaporates on material surface convert steam and waste gas to.In the material folding process, under 12 effects of the gas collection collet on fixing and the outer cylinder body, change the direction that moves down of material, make material between tapered gas collection collet 12 bottoms and drying cylinder body 4, form bed of material plane, between tapered gas collection collet 12 rear portions and drying cylinder body 4 and top, bed of material plane form the gas collection space, the steam that produces after the heat exchange and the effect of waste gas finished of collecting played in this space.Steam and waste gas is through steam vent 9, enter run through with drier body each air inducing flue 8 up and down in, rely on the effect of air-introduced machine 5, steam and waste gas are entered among the atmosphere.Form and ring-likely material bedly in the process that slowly moves, finish heat exchanging process from top to bottom, reach the oven dry purpose of material.Material after the oven dry falls in the discharging awl bucket 16.According to requirement,, finish the drying course of material by heat-resisting belt conveyor 17 dischargings of the speed governing of dryer bottom to the material moisture after the oven dry.
