Abstract
A kind of single blower fan circulatory afterheat recycling device being applicable to small-size grain drying machinery, it is drying section that described device comprises top, bottom is the dryer main frame of cooling section, and the drying section waste gas outlet be arranged in drying section and drying section hot air chamber, be arranged on upper cooling section cold wind import and the cooling exhaust air compartment of cooling section, it is characterized in that: the air outlet of described cooling exhaust air compartment is connected with thermal source hot air chamber by cooling exhaust pipeline, the air outlet of described thermal source hot air chamber is communicated with the air inlet of drying section hot air chamber with the Fans be arranged between pipeline by hot air duct.The utility model only uses a Fans, while normally sending hot blast to dryer, can realize the recycling to foodstuff drying device cooling section waste heat, to reduce oven dry energy consumption during small-size grain drying machinery oven dry operation.
Description
Technical field
The utility model relates to a kind of heat recovery technology be applied in grain drying device, is a kind of single blower fan circulatory afterheat recycling device being applicable to small-size grain drying machinery specifically.
Background technology
The now widely used foodstuff drying device of China all adopts convection current heating power drying mode, and namely utilize hot-air directly to contact with grain, heat passes to grain in the mode of convection current, and the temperature of grain is raised, and inner moisture vaporization, reaches dry object.Hot blast temperature after heat release declines, and carries the moisture of vaporizing out in grain and discharge outside dryer as oven dry waste gas.Grain after oven dry is higher due to grain temperature, cannot safe storage, must lead to overcooled mode and the temperature of grain is down to safe storage temperature then goes out machine.The cooling of grain all uses the mode of cross-ventilation cooling at present, and namely contacted with grain by cold air, the heat in hot grain passes to cold air by the mode of convection current, the temperature of grain is declined, reaches the object of cooling.After cold air absorbs the heat in grain, temperature raises, and becomes cooling exhaust and discharges outside dryer.
Dryer discharge oven dry waste gas and cooling exhaust in, cooling exhaust is owing to having certain temperature, and humidity is lower, so can recycle heat contained in cooling exhaust, effectively to reduce the heat exhaustion of dryer, reduce drying machine drying cost.
Summary of the invention
One single blower fan circulatory afterheat recycling device simply and easily that the purpose of this utility model provides for the waste heat recovery in the cooling exhaust of small-size grain drying machinery just.
The main design thought of the utility model waste-heat recovery device is only to use a Fans can while normally sending hot blast to dryer, the cooling exhaust raised through temperature after dryer cooling section is sucked thermal source hot air chamber by cooling exhaust air compartment, cooling exhaust pipeline, as the air distribution of thermal source, mix with the hot blast carrying out self-heat power after after the hot blast temperature reaching suitable, enter drying machine drying section, heating, drying is carried out to the grain in dryer.Because the temperature of cooling exhaust is higher than environment temperature, waste heat contained in the heat that its temperature gap is formed i.e. cooling exhaust is just recycled.
Concrete technology of the present utility model is arranged as follows:
The single blower fan circulatory afterheat recycling device being applicable to small-size grain drying machinery of the present utility model, described device comprises the dryer main frame that top is drying section, bottom is cooling section, and the drying section waste gas outlet be arranged in drying section and drying section hot air chamber, the upper cooling section cold wind import being arranged on cooling section and cooling exhaust air compartment; The air outlet of described cooling exhaust air compartment is connected with thermal source hot air chamber by cooling exhaust pipeline, and the air outlet of described thermal source hot air chamber is communicated with the air inlet of drying section hot air chamber with the Fans be arranged between pipeline by hot air duct.
The beneficial effects of the utility model are as follows:
Because single blower fan of the present utility model circulating waste heat reclaiming process route is simple, only need from setting up a cooling exhaust air compartment and a cooling exhaust pipeline on normal dryer process route, can utilize to the air-heater of dryer hot wind supply while normally sending hot blast to dryer, the cooling exhaust raised through temperature after dryer cooling section is passed through cooling exhaust air compartment, cooling exhaust pipeline sucks thermal source hot air chamber, as the air distribution of thermal source, mix with the hot blast carrying out self-heat power after after the hot blast temperature reaching suitable, enter drying machine drying section, heating, drying is carried out to the grain in dryer, process route is simple, practical manufacture and operating cost low, be specially adapted to the small-size grain drying machinery application using separate unit air-heater.

Detailed description of the invention
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1, the single blower fan circulatory afterheat recycling device being applicable to small-size grain drying machinery of the present utility model, described device comprises the dryer main frame that top is drying section 1, bottom is cooling section 3, and the drying section waste gas outlet 2 be arranged in drying section 1 and drying section hot air chamber 5, is arranged on cooling section cold wind import 4 on cooling section 3 and cooling exhaust air compartment 6; The air outlet of described cooling exhaust air compartment 6 is connected with thermal source hot air chamber 10 by cooling exhaust pipeline 9, and the air outlet of described thermal source hot air chamber 10 is communicated with the air inlet of drying section hot air chamber 5 with the Fans 7 be arranged between pipeline by hot air duct 8.
It is as follows that the utility model sketches operation principle of the present utility model below in conjunction with Fig. 1:
During dryer work, the grain in dryer moves under gravity from the top down, and air-heater operates, and extracts the hot-air in thermal source hot air chamber and is sent in dryer by hot air duct and dryer hot-flow flue, drying the grain in dryer.Simultaneously, due to the work of air-heater, be negative pressure state in thermal source hot air chamber, under the effect of thermal source hot air chamber negative pressure, cold wind enters dryer by cold air inlet, cools to the hot grain of dryer cooling section, and after cold wind absorbs the heat of hot grain, temperature raises, enter thermal source hot air chamber by cooling exhaust pipeline, thus play the object to heat recovery in cooling exhaust.Whole oven dry and waste heat recovery only use an air-heater, and the cold wind of the hot blast of drying and cooling is circulated by air-heater, and total is simple and practical.
