Abstract

The utility model relates to a structural design of a solar heating mushroom shed for special production equipment for edible fungi. In the design, a structure composed of a skeleton foam plastic composite shed roof and a brick-concrete enclosure is used, and a light-transmitting plastic film and The foam insulation material forms a circular convection channel, which makes full use of the solar energy directly entering the film in the channel to form a thermal circulation air flow into the shed, thereby solving the contradiction between solar heating and direct light entering the shed, and forming an efficient and no external heating source. Bacteria dedicated mushroom shed. The production can be realized throughout the year, the cost is low, the service life is long, and energy is saved, which is a major improvement in the industrial production of edible fungi.

Description

Convective loop formula solar heating mushroom canopy

The utility model belongs to a kind of edible mushroom production equipment special.

Along with the development of human civilization history, great change has taken place in eating patterns.Edible mushroom enters human recipe as high-nutrition health-care food, and is accounting for more and more important position.The wilderness demand of domestic and international market has impelled Edible Fungi to develop rapidly from family breed and has become large scale business enterprise's production.For the edible fungi growth facility that adapts to its production development special use also more and more occurs.Yet the growth conditions of edible mushroom has very big difference with general plant.It had both needed uniform temperature, can not be too high, but also can not be too low.He needs certain illumination again, but can not be too strong.Naked thing forms greenhouse direct projection meeting and causes edible mycelia or sporophore growth to suppress, even withered.So the major function of present special-purpose mushroom canopy is to regulate light and warm contradiction.How to utilize solar thermal energy again, not making its illumination again is excessively by force present basic design principle.At present both at home and abroad this kind equipment has three classes, and the one, what common brick mixed, brick is wooden or brick and other new composite are used with, room ridge formula structure.Because adopt light-proof material, the solar energy utilization is poor, insulation, heat insulation also relatively poor, the cost height is suitably used in season.It two adds the skeleton mushroom canopy that straw screen or mat is formed by plastics, metal, bamboo wood.Utilize straw mat, the sponge of adding a cover on the frame to wait and shelter from heat or light, be incubated, preserve moisture, be made generally in circular arch type or ridge-roof type (single slope or two sloping types).It utilizes thing sunshade such as straw mat, preserves moisture, and just can't utilize solar temperature rising, so temperature can't be used when low.And the straw mat loss is big, and temperature is regulated difficulty, also can only use in short-term in some areas.It three is the modernized booths that rose modern age, adopts steel wood to mould and mixes the skeleton ceiling, establishes heating and moistening in the canopy, cooling system.Metal adds foam composition insulation skeleton and has good thermal property, and can carry out the four seasons and produce, but the cost height, big energy-consuming can't accomplish that equally few daylighting utilizes the effect of solar heat simultaneously again, cost is too expensive, is difficult for applying at home.

Goal of the invention of the present utility model promptly is to solve solar energy mushroom canopy, should take suitable low-light (level) lighting quantity, utilize the contradiction of solar energy again, design a kind of special-purpose mushroom canopy of solar heating of new-type structure, realize need not the effect that external energy is realized four seasons operation.

For realizing above purpose, the present invention adopts the utilization of indirect type solar energy, avoids the sunshine direct projection to go into canopy, is transform light energy the contradiction that the mode of heat energy solves light and heat.Concrete way is: adopt skeleton and insulation foamed plastic composite structure, sunshine can not directly be entered in the canopy by ceiling, whole frame is the same with common mushroom room structure to be located on the mixed pad of brick wood or brick.Different is, the sunny slope of ceiling has partly been taked special construction, between utilizing the transparent mold that the upper skeleton upper berth is applied in the double-deck skeleton and being attached between the heat-insulating material on the lower skeleton, forms a cellular convection space path.Below path, be provided with an air inlet, above circulation canal, have a gas outlet, like this, between transparent mold and heat-insulating material, just formed a preheating space near the ceiling place near the pad place.If on the heat-insulating material surface, apply one deck black matrix material again, then the sunshine of injecting by mold promptly can be absorbed preferably, and be released in fully among this airtight space with the black body radiation form, form the rapid rising of temperature, the intensification air-flow follows the negative pressure that the rising of ring path causes the passage air inlet, thereby finish the convection circulation of thermal current effectively, the heat that solar energy is formed is fully utilized, but the illumination of the sun does not have too much transmission to advance canopy, thereby solved daylighting effectively, the contradiction that heating can not take into account, one of key of the present invention just.

How further specify goal of the invention of the present utility model below in conjunction with accompanying drawing realizes.

Fig. 1 is for being structural representation of the present utility model.

Wherein 1 is upper skeleton, and 2 is lower skeleton, and 3 is heat-insulating material, 4 is the circulative convection path, and 41 is air inlet, and 42 is the gas outlet, 5 is the check valve block, and 6 is intake valve, and 7 for forcing discharge window, 8 is southern window, 9 is the north window mouth, and 11 is pad, and 11 is the backwater edge, 12 is the printing opacity plastic film, and 13 represent the black matrix material layer.

From the accompanying drawing as can be seen, can form the cycling hot air-flow soon on the date that sunshine is arranged, the solar charging zoning of direct projection is gone in the canopy, guaranteed the more weak light that enters indirectly again simultaneously, so even the insulation problem also can be realized in the winter time preferably in such mushroom room.When temperature is too high, can close this circulating current, concrete method is, can add a valve 6 at air inlet 41 places, and the pressure discharge window 7 of a band valve can be set in 42 places, ceiling gas outlet simultaneously.Non-return valve diaphragm 5 is set in the convection circulation energy circuit, is the reverse counterflow that formed after night in winter, canopy was lowered the temperature outward in order to prevent.In order further to strengthen adaptability has the north and south symmetry on the pad that frame is located in convection current window 8,9.When temperature is high, the cooling of can directly windowing, the temperature and humidity in the controlling chamber causes the environment that helps edible fungi growth effectively.

Through evidence in a year, the utility model can fully obtain solar heat, do not have winter and can make room temperature be adjusted in 18-20 ℃ under any heating situation, minimumly be not less than 10 ℃, summer, average canopy temperature was 26-31 ℃, than existing low 3-5 ℃ of the mushroom room of covering, illumination is adjustable in the 10-1000 lux, and particularly its cost is at 60 yuan/m ²Below, be service life 30 years, have remarkable social benefit and economic benefit.
