The phase -change thermal material is arranged in hollow concrete block's outmost cavity, and straw compression piece is arranged in all the other all cavitys of hollow concrete block. The utility model provides a phase -change thermal type straw concrete block, keep warm effectual, wall body construction convenience is swift to the requirement that possesses endothermic heat accumulation characteristic simultaneously and satisfy the bearing.
Description
One, technical field
The utility model relates to a kind of phase change heat storage type straw concrete block, is specially adapted to building by laying bricks or stones of solar greenhouse wall body.This building block makes full use of and make use of agricultural wastes straw, and has phase-transition heat-storage layer, is conducive to the insulation in greenhouse and energy-conservation, and meets the requirement of load-bearing.
Two, background technology
Greenhouse is the agricultural industry of a highly energy-consuming, according to the Statistics, the annual agricultural production energy input in the whole world 35% for greenhouse.According to Chinese agriculture greenhouse net statistics, national greenhouse production area more than 1,500 ten thousand mu, wherein more than 85% is all adopt the additional fire coal of solar energy to the mode of greenhouse heat supply.On daytime, when intensity of solar radiation is larger, the too fast temperature even exceeded required for plant growth of warm interior temperature rising, needs to open a part of plastic sheeting and outwardly discharges unnecessary solar thermal energy; And night is again by the mode of coal stove heat supply, maintain chamber environment temperature.Effectively can not utilize the solar energy of preciousness on daytime like this, also need night to consume fossil energy, cause environment pollution; Rising steadily also due to energy prices, causes the increase of booth cost of production simultaneously.
Solar greenhouse wall body is that especially north wall should have heat absorption, accumulation of heat, the function of insulation, and the materials for wall that exploitation is suitable for and correctly design body of wall are the Important Problems of facilities horticulture engineering circles research always.Phase change heat storage material is used for greenhouse north wall inner surface, absorb solar thermal energy daytime and store, discharge in the evening again, is conducive to maintaining the temperature in greenhouse, reduces the consumption of the energy.
Three, summary of the invention
The object of the invention is to provide a kind of good heat insulating, have heat absorption and heat storage characteristic and meet the greenhouse wall body building block of load-bearing requirements, comprises concrete hollow block, straw compression block, phase change heat storage material.
Its major design content is:
(1), concrete hollow block 1 has many rounds, and is between every round and is staggered in arrangement, and extends the path that heat transmits, increases the thermal resistance of heat transfer.Ensure the thickness of concrete hollow block 1 rib, to meet the requirement of its load-bearing simultaneously.The hole of placing phase change heat storage material 3 is through hole, and will place this one side of phase change heat storage material as greenhouse wall body inner surface.
(2), using heat accumulating phase change material 3 as being placed in the outermost layer cavity of concrete hollow block 1 as heat absorption and heat storage layer, straw compression block 2 is placed in all the other cavitys of concrete hollow block 1 as insulation layer as heat insulating material.
Four, accompanying drawing explanation
Fig. 1 is phase change heat storage type straw concrete block cross sectional representation.
In figure, 1 is concrete hollow block, and 2 is straw compression blocks, and 3 is phase change heat storage materials.
Five, detailed description of the invention
As shown in Figure 1, the phase change heat storage type straw concrete block that the utility model provides is made up of hollow concrete building block 1, straw compression block 2, phase-transition heat-storage layer 3.
Phase-transition heat-storage layer 3 is positioned at the outermost layer cavity of hollow concrete building block 1.During use, insert in the outermost layer cavity of hollow concrete building block 1 after phase change heat storage material is melted and make.When building greenhouse wall body by laying bricks or stones, this one side at phase-transition heat-storage layer place should as the inner surface of greenhouse wall body.
The making of straw compression block 2, first by crushed stalk, then admixes lime, the materials such as water, and after then putting into mould cold moudling, natural drying was made after 30 days in atmosphere.Straw compression block 2 is inserted in all the other cavitys in hollow concrete building block 1 except phase-transition heat-storage layer cavity used.Straw compression block 2 has heat-insulation and heat-preservation, the feature such as fire-retardant, anti-mildew, makes agricultural wastes straw be able to recycling.
Hollow concrete building block 1 is by cement, and sandstone, water, the materials such as polypropylene fibre, according to testing the match ratio determined in advance, to be shapingly in a mold made.The design of this hollow concrete building block extends heat bang path length, improves building block thermal resistance, thus reaches the effect of the thermal and insulating performance improving blockwork.Block designs considers the requirement of the weight capacity of building block, overall uniform force, and bearing is good.
The present embodiment hollow concrete building block 1 has the function of thermal insulation and load-bearing, straw compression block 2 insert the thermal and insulating performance that further enhancing this building block, the form of structure of phase-transition heat-storage layer 3 is conducive to the storing heat when greenhouse temperature is higher, discharge when greenhouse temperature is lower, thus energy-conservation advantageously in heliogreenhouse.
The phase change heat storage type straw concrete block that this enforcement provides has following characteristics: thermal and insulating performance is good; The requirement of thermal insulation directly just can be met with this concrete block masonry greenhouse wall body, without the need to adopting the measures such as outer wall heat insulating again, thus speed of application block, reduce labour intensity; This building block has the function of load-bearing, build the requirement that greenhouse wall body can meet load-bearing; This building block has phase-transition heat-storage layer, can absorb store heat when greenhouse temperature height, discharges, decrease the consumption of the greenhouse energy, be beneficial to greenhouse energy saving and environment conditioning when greenhouse temperature is low.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacements, improvement etc., all should be included within scope that the utility model protects.
Claims (2)
1. phase change heat storage type straw concrete block, combined by concrete hollow block 1, straw compression block 2, phase change heat storage material 3, it is characterized in that this building block has high insulating effect, wall construction speed is fast, there is heat absorption and heat storage characteristic and the requirement meeting load-bearing, be particularly useful for building by laying bricks or stones of solar greenhouse wall body.
2. phase change heat storage type straw concrete block according to claim 1, it is characterized in that phase change heat storage material 3 is arranged in the outermost layer cavity of described concrete hollow block 1, described straw compression block 2 is arranged in all the other inner all cavitys of concrete hollow block 1.
