Description

The low temperature dewatering dryers of using more

The utility model relates to dry materials equipment, and particularly suitable carries out the low temperature dewatering drying to organic plant.

At present more to the device category of dry materials, it comprises microwave, and infrared steam conducts heat, flue gas direct baking, heated-air drying, electrothermal drying, low-pressure low-temperature drying etc.Above-mentioned various drying equipment scarcely is suitable for the drying of organic plant, and especially to the drying of green feed, this is because the water content height of green plants own, if adopt the equipment of above-mentioned drying, exist the production cost height, yield poorly, big energy-consuming can not large tracts of land be promoted the use of.Simultaneously, be easy to destroy the nutrition of green plants.Cause certain degree of difficulty for large-scale developing and utilizing the processing of green plants and agricultural-product.

The purpose of this utility model has been to provide the equipment of the low temperature dewatering oven dry of the bar, stem, leaf of a kind of processing and utilization green plants, climing, careless, dry fruit, grain, medicinal material, capsicum, tobacco leaf etc.

The technical solution that realizes goal of the invention is: the outlet of hot-air blower is connected the top of hot-blast stove, and the outlet of coal-fired air blast is connected with the hot-blast stove burner hearth.Improvements of the present utility model are on the top of hot-blast stove with the garden hot blast villous themeda of many hierarchal arrangement, the place ahead at garden hot blast villous themeda one end is provided with primary air separating duct, the other end of garden hot blast villous themeda is connected with tympanites buffer compartment cigarette frame, the primary air separating duct dividing plate is connected with preceding villous themeda frame resistance cigarette dividing plate, the outside, back air channel also is provided with at least 6 square hot blast villous themedas, and its side's hot blast villous themeda is to be connected one with square hot blast villous themeda every the cigarette frame.Establish the back smoke baffle plate at the rear of square hot blast villous themeda and be connected every the cigarette frame with square hot blast villous themeda, bottom at hot-blast stove is provided with the combustion chamber, with the back smoke baffle plate connects feeder arranged, the two ends of double-deck oven dry tube are connected with the labyrinth joint respectively, and the other end of labyrinth joint is connected to feeder and goes out on vapour tower and the pulverizer, make it hermetically sealed, double-deck oven dry tube is connected as one by 6 demarcation strips and inner core at least.Simultaneously, double-deck oven dry tube is to drive rotation by reductor and travelling gear, and supports double-deck oven dry tube with a plurality of support rollers, and flue gas enters chimney through the front and back twice between cigarette.

The utility model is that heating energy source is sent into the oven dry tube after with air heat owing to adopt with coal compared with prior art, and the oven dry tube adopts polygonal structure again and rotates, the material heating surface area of being dried is increased, thereby improved drying efficiency, output is big, and cost is low.Provide feasible approach for the bar that requires grass cultivation production cheaply and multiple green plants, stem, leaf, the climing feed that is processed into.Promote the development of aquaculture and open for the utilization of green discarded object and kept away a new world, it is except drying above-mentioned plant, also can be used as the oven dry of fruit, dewatering vegetable, grain, capsicum, tobacco leaf, medicinal material, chicken Swine, groove slag etc., purposes is very extensive.Simultaneously, this equipment belongs to low temperature drying, kept the nutrition in the plant preferably, had compact conformation, high efficiency, energy consumption are low, price is than the characteristics of much lower times of import equipment, its technical parameter is oven dry amount 0.5T～10T/ day, 65～85 ℃ of temperature, coal consumption 10Kg～120Kg/h, capacity 500～9990m3/h, power consumption 1.5～10KW.By the oven dry thing is any color before oven dry, still keeps primary colors constant after the baking.

The blue or green cornstalk leaf that adopts this dryer to take advantage of green grass or young crops and dry by the fire, blue and white living cissoid, blue or green sweet potato cissoid, pine needle, acacia, clover are except the preservation volume is little, and prior advantage is that nutrition is not destroyed.Fowl eats the height of laying eggs, and how long poultry eats meat.Solved the peasant because sufferings that cloudy weather for several days running can not cool be dried grain in the sun and herdsman herd for a long time and to lack the winter and deposit the difficulty of herbage.

Below in conjunction with accompanying drawing content of the present utility model is elaborated:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the hot-blast stove front view of Fig. 1;

Fig. 3 is the perspective view of Fig. 2;
