Abstract
The utility model discloses a heat recovery drain dryer. The lower end of a shell (1) is connected with a heat recovery grain cooling drum (2) which is provided with small conical shunting screens (3) and small funnel-shaped leakage screens (4) in an interlacing way from top to bottom, wherein an opening at the center of the small leakage screen (4) at the bottom is connected with a discharge tube (5); the discharge tube (5) extends out of the heat recovery grain cooling drum (2); the side surface of the heat recovery grain cooling drum (2) is connected with a blower (6); and the connecting part of the blower (6) and the heat recovery grain cooling drum (2) is arranged below the small leakage screen (4) at the bottom. In the utility model, the heat recover grain cooling drum is added at the discharge end of the original dryer, therefore the utility model has the functions of recycling the waste heat and directly storing the dried grain without further processing, the energy is saved, the working procedures are reduced, and the labor intensity is reduced as well.
Description
Technical field
The utility model belongs to a kind of drying machine.The crop dryer of a kind of waste heat recovery specifically.
Background technology
At present, crop dryer is mainly the circular cylinder body shape, being divided into the upper and lower part is dryer section and bringing-up section, described housing upper end is provided with moisture air outlet and cereal feed pipe, be staggeredly equipped with the shunting sieve and the funnel shaped leakage material screen of taper in the dryer section from top to bottom, evenly have through hole on this shunting sieve and the leakage material screen.Shunting sieve and leakage material screen central lines, and shunt the sieve diameter greater than the diameter that leaks the material screen central opening, a wherein bottom leakage material screen central opening connection discharge nozzle.Be positioned at bottom one and leak the heater that the material screen below is provided with the suit radiator, this heater next door is provided with temperature sensor, and this section is a bringing-up section.The dryer section upper end is provided with moisture air outlet and charging aperture.Cereal enters from the charging aperture machine, discharges through discharging opening from top to bottom, and air is discharged moisture from bottom to top by the heater heating by the moisture air outlet, grain-drying is very convenient, but also not really perfect at present.Cereal through discharging opening has very big hot gas, also needs tiling to dry in the air a period of time, could store.The hot gas that cereal is taken out of is dissipated in the air, fails well to utilize, very consumes energy.
The utility model content
It is a kind of with waste heat recovery that technical problem to be solved in the utility model is to provide, the recuperation of heat crop dryer that dried cereal is directly stored.
The technical solution of the utility model is as follows: a kind of recuperation of heat crop dryer, comprise housing, on this housing, the bottom is divided into dryer section and bringing-up section, described housing upper end is provided with moisture air outlet and cereal feed pipe, its key is: described housing lower end is connected with recuperation of heat cereal cooling cylinder, be staggeredly equipped with the little shunting sieve and the funnel shaped little leakage material screen of taper in this recuperation of heat cereal cooling cylinder from top to bottom, described little shunting sieve and little leakage material screen central lines, and described little shunting sieve diameter is greater than the diameter of little leakage material screen central opening, a wherein bottom little leakage material screen central opening connects discharge nozzle, this discharge nozzle stretches out outside the recuperation of heat cereal cooling cylinder, described recuperation of heat cereal cooling cylinder side is connected with air blast, and this air blast and recuperation of heat cereal cooling cylinder junction are positioned at a bottom little leakage material screen below.Air blast blows back bringing-up section and dryer section again with the hot gas of cereal in the recuperation of heat cereal cooling cylinder, reaches waste heat recovery is utilized again, is used for the epimere heating.Because the wind that air blast blows back to recuperation of heat cereal cooling cylinder is cold wind, cereal blows hot gas through cold wind one and disperses by this section simultaneously, and as dried cereal, tiling has been dried in the air a period of time, can directly store.
The outlet of above-mentioned discharge nozzle lower end is provided with baiting valve, makes things convenient for the blowing operation.
Above-mentioned housing upper end is the awl section, and these housing upper end awl section central authorities are provided with the moisture air outlet, the oblique cereal feed pipe that is inserted with of described housing upper end awl section wall.
Be staggeredly equipped with large shunt sieve and the big material screen that leaks in the above-mentioned housing from top to bottom, be positioned at the heater that a bottom big leakage material screen below is provided with the suit radiator, this heater next door is provided with temperature sensor.Temperature sensor and the heater temperature during together to drying is controlled automatically.
Above-mentioned housing and recuperation of heat cereal cooling cylinder outer surface are enclosed with heat-insulation layer.Keep the interior heat of housing and recuperation of heat cereal cooling cylinder to be difficult for scattering and disappearing.
Beneficial effect: the utility model is simple in structure, reasonable in design, has increased a recuperation of heat cereal cooling cylinder at former drying machine discharge end, utilizes again with recovery waste heat, drying cereal does not need row to handle again, and directly the function of Chu Cuning has been saved the energy, reduce operation, reduced labour intensity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of recuperation of heat crop dryer of the utility model, form by housing 1, recuperation of heat cereal cooling cylinder 2 and air blast 6 etc., this housing 1 upper and lower part is divided into dryer section and bringing-up section, described housing 1 upper end is the awl section, these housing 1 upper end awl section central authorities are provided with moisture air outlet 1a, the oblique cereal feed pipe 1b that is inserted with of described housing 1 upper end awl section wall.Be staggeredly equipped with large shunt sieve 8 and the big material screen 9 that leaks in the described housing 1 from top to bottom, be dryer section, the cereal feed pipe 1b port of export sieves 8 centers over against the large shunt in the top.Be positioned at the heater 10 that a bottom big housing 1 that leaks material screen 9 belows is provided with suit radiator 11, these heater 10 next doors are provided with temperature sensor 12, are bringing-up section.Described housing 1 lower end is connected with recuperation of heat cereal cooling cylinder 2, be staggeredly equipped with the little shunting sieve 3 and the funnel shaped little leakage material screen 4 of taper in this recuperation of heat cereal cooling cylinder 2 from top to bottom, described little shunting sieve 3 and little leakage material screen 4 central lines, and the diameter of 3 diameters greater than little leakage material screen 4 central openings sieved in described little shunting, wherein bottom little leakage material screen 4 central openings connect discharge nozzle 5, this discharge nozzle 5 stretches out outside the recuperation of heat cereal cooling cylinder 2, and the outlet of described discharge nozzle 5 lower ends is provided with baiting valve 7.Described recuperation of heat cereal cooling cylinder 2 sides are connected with air blast 6, and this air blast 6 is positioned at bottom little leakage material screen 4 belows with recuperation of heat cereal cooling cylinder 2 junctions.Large shunt sieve 8, leak on material screen 9, little shunting sieve 3 and the little leakage material screen 4 and be evenly distributed with through hole greatly.Described housing 1 and recuperation of heat cereal cooling cylinder 2 outer surfaces are enclosed with heat-insulation layer 13.
