Abstract

The utility model relates to a fast high-temp solar drier, which comprises a heat collector (1) with a cold air intake (2) and a hot air outlet (3); the hot air outlet (3) is connected with a drier through a fan (4); the heat collector (1) is provided in turn with a protective layer, an insulation layer and a heat absorption layer on both sides and bottom, and an euphotic layer at the top; between the euphotic layer and the heat absorption layer a hot air channel is formed. The heat collector of the utility model has advantages of big heating area, shallow depth, good heat absorption effect and fast heating up, thereby improving the drying effect.

Description

The quick high-temp solar dryer

Technical field

The utility model relates to a kind of drying equipment, particularly a kind of quick high-temp solar dryer.

Background technology

Solar energy is a kind of inexhaustible, nexhaustible energy.Heliotechnics is fully used, from generating electricity, warm oneself, supply water various solar power plants, uses very extensive.

At present, utilize solar energy to carry out dry device, operation principle is identical, and the structure basically identical generally comprises heat collector, the import of heat collector, outlet, and outlet connects hothouse through blower fan.During use, wind enters heat collector from import, and coming out through heat collector just is hot blast, and hot blast is sent into hothouse just can carry out the drying processing to the article in the hothouse.But because the unreasonable structure of heat collector, the utilization ratio of solar energy is low, and influence is applied.

Summary of the invention

The purpose of this utility model provides that a kind of cost is low, endothermic effect good, quick heating and the higher quick high-temp solar dryer of temperature.

The purpose of this utility model can realize by following technical measures:

A kind of quick high-temp solar dryer; heat collector is arranged; heat collector has cold air inlet, hot-blast outlet; hot-blast outlet connects drying device through blower fan; described heat collector both sides and bottom ecto-entad be matcoveredn, heat-insulation layer and heat-sink shell successively; photic zone is arranged at the top, forms the hot-air channel that can absorb heat between photic zone and the heat-sink shell.

The cold air inlet of heat collector and air channel shape, big or small consistent.

Cold air inlet at heat collector is equipped with stainless (steel) wire.

Wide 500～the 2000mm in described air channel, high 80～150mm.

Heat collector of the present utility model both sides and bottom are made up of protective layer, heat-insulation layer and heat-sink shell; it between photic zone and the heat-sink shell air channel; and the wide 500～2000mm in air channel, high 80～150mm can guarantee that the heating surface area in air channel is big; depth as shallow; endothermic effect is good like this, and quick heating is when air flow to when outlet from the heat collector import; the temperature of air can reach required numerical value, thereby improves drying effect.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of quick high-temp solar dryer, heat collector [1] is arranged, heat collector [1] has cold air inlet [2], hot-blast outlet [3], and hot-blast outlet [3] is connected to drying device [5] through blower fan [4], and described heat collector [1] is the strip structure, both sides and bottom ecto-entad be matcoveredn [7], heat-insulation layer [8] and heat-sink shell [9] successively, heat-sink shell [9] adopts metallic plate to make, as aluminium sheet, galvanized sheet etc., and at the surface of heat-sink shell [9] coating heat-absorbing material; Photic zone [11] is arranged at the top, photic zone [11] has one deck or two-layer, what show among Fig. 3 is two-layer, make by glass plate or other transparent material, photic zone has 10～25mm gap between [11], is formed with the hot-air channel [6] that can absorb heat, the wide 500～2000mm of hot-air channel [6] between photic zone [11] and the heat-sink shell [9], high 80～150mm, length is not limit.The cold air inlet [2] of heat collector [1] and hot-air channel [6] shape, size are consistent, and at cold air inlet [2] 3～10 purpose stainless (steel) wires [10] are installed, and are used to filter the air that is sucked, and prevent that birds from entering blower fan, causes accident.

Described drying device [5] has hot-wind inlet [13], exhaust outlet [18]; this drying device [5] ecto-entad has skin [14], heat-insulation layer [15] and protective layer [16] successively; there is placement to need the cavity [17] of dry article between the protective layer [16] at bottom and top; corresponding empty cavity position is equipped with door [12] in the outside of hothouse [5], sees Fig. 4.This drying device [5] is mainly used to dry fruit, fruit product, paddy and other cereal product etc.

Fig. 5 is the structure chart of the another kind of form of drying device.This drying device [5] comprises housing and the interlayer and the hot-wind inlet [13] that are placed in the housing, and the size of interlayer is corresponding with the inner chamber of housing.Its middle shell is made up of left and right sides side plate [20], front and back side plate [19] and base plate [24], left and right sides side plate [20] is movable, its lower end and base plate [24] are hinged, the upper end is equipped with buckling piece [25] and can be fastened with front and back side plate [19], unclamp buckling piece [25], left and right sides side plate [20] can outwards overturn respectively and become a plane with base plate, sees Fig. 6, the convenient dry goods that takes out.Front and back side plates [19] are fixedlyed connected with base plate [24].Being used for placing dry article above the interlayer, be inlet air plenum below the interlayer, and this interlayer is made up of dividing plate [22] and the stratum reticulare [21] that is installed in above the dividing plate, and the interval has wind hole [26] on the dividing plate [22], is bearing on the base plate [24] by leg [23].Hot-wind inlet [13] is opened at preceding side plate [19] and is gone up the connection inlet air plenum.This drying device [5] is mainly used to dry salt etc.In addition, for preventing the salt caking, can transit mixer be set in drying device [5] lining.

The utility model in use, start blower fan [4], cold air is drawn into heat collector [1] from cold air inlet [2], in the process of the hot-air channel of flowing through [6], absorbing the solar energy temperature raises, hot-blast outlet [3], blower fan [4] through heat collector enters drying device [5] then, and the article (as salt or fruit, fruit product, paddy and other cereal product etc.) that leave drying device [5] lining in are carried out heat drying.Its moisture is constantly taken away by hot blast, reaches dry purpose.
