Description

Many thermals source agricultural byproducts drying equipment

Technical field

The utility model relates to a kind of many thermals source agricultural byproducts combined drying complete set of equipments.

Background technology

China is that an energy lacks country, how to tap a new source of energy, and fully excavating, make good use of regenerative resource is the new problem that current China faces.Solar energy, geothermal energy, wind energy, ocean energy etc. all are the renewable and clean energy resources that can develop.Carry out better relatively in the development and use of China's solar energy, and the development and use of geothermal energy just are inferior to the former, originally use preferably just people and live and use hot water, build hot spring and develop tourist attractions etc., utilize the enterprise of geothermal energy few in the production.For example: some factories that are located in GEOTHERMAL WATER aboundresources (water temperature is up to 70 ℃) all adopt dry agricultural byproducts of local method such as fresh mushroom, promptly will burn hot blast that bavin produces with air blast blasts in the kiln bright mushroom is carried out drying, the dry fresh mushroom of local method is except waste timber resources, dry of low quality (because uneven drying is spared with duration, dry mushroom, thereby can being with cigarette to smoke flavor, mushroom influences mouthfeel), the staff need ceaselessly add the bavin material, labour intensity is big, and operating efficiency is low.

Summary of the invention

The purpose of this utility model is to provide a kind of equipment that makes full use of the multiple thermal source complementary heat supply realization of renewable and clean energy resource to the agricultural byproducts combined drying.

For realizing above purpose, the utility model has been taked following technical scheme: a kind of many thermals source agricultural byproducts drying equipment, include the dry kiln body, has a surperficial Temperature Humidity Sensor that contacts and be connected with this dry kiln body with the dry control appliance that is arranged on the external side of dry kiln, also include the heat exchanger that is arranged in the dry kiln body, the underground heat water pump that is connected by pipeline with heat exchanger is provided with solar thermal collector on this dry kiln external body top and solar thermal energy is sent to air-introduced machine in the dry kiln body.

Temperature Humidity Sensor is finished the measurement that dry kiln internal milieu humiture is changed, and the environmental change in the reflection kiln body is delivered to dry control appliance with the parameter value that changes; This equipment is the intellectualizing system that has adopted computer technology, after the signal that it brings Temperature Humidity Sensor amplifies processing, setting the humiture parameter through mould/number conversion on the one hand with control system compares, body heating of control dry kiln and hydrofuge equipment, keep the interior agricultural byproducts of kiln to be in the optimum drying state, give intelligent dry control appliance main control computer LCDs on the other hand and show; Solar thermal collector changes solar energy into heat energy to be sent in the dry kiln body by air-introduced machine, the underground heat water pump is sent into heat exchanger generation heat in the kiln with GEOTHERMAL WATER by pipeline, these two kinds of heat generation equipment are supplying heat sources of agricultural byproducts combined drying, make the energy consumption of agricultural byproducts dry run and financial cost drop to minimum.

Also comprise hot-blast stove, this hot-blast stove is communicated with described dry kiln body by pipeline, and described air-introduced machine is arranged in the dry kiln body, the exit of pipeline.Hot-blast stove can be as auxiliary heating system, require when higher at kiln temperature, perhaps when solar energy, geothermal energy heat supply make kiln temperature still not reach the temperature of the drying process benchmark of setting in the dry control appliance, dry control appliance starts the warm air oil furnace auxiliary heat supplying, air-introduced machine is sent into hot blast in the dry kiln body, it is heated up, and air-introduced machine is arranged on the outlet of pipeline, make hot blast that hot-blast stove produces can be in time, guided in the dry kiln body by air-introduced machine fast.

Also include the circulating fan that is electrically connected with described dry control appliance, this circulating fan is fixed on the dry kiln body inwall, and circulating fan can be finished the balance transmission to the dry kiln intimate heat, makes humiture equilibrium in the kiln body.

The utility model compared with prior art, has following advantage: utilize each department renewable and clean energy resource such as solar energy, geothermal energy advantage, form the thermal source supplying of multi-energy complementation flexibly to the agricultural byproducts drying, adopt intelligent control system, intelligent, automaticity is high, antijamming capability is strong; Measure accurately, the supply of control thermal source is stable, and the article dry mass is good; It is minimum that the energy consumption of agricultural byproducts dry run and financial cost are dropped to, and shorten dramatically than local method drying time, and quality improves, and reduces personnel labor intensity, and stability and security are good, i.e. economy environmental protection again.
