Description

Detailed Description of the Invention

Industrial application fields

  The present invention relates to the cultivation of facilities such as fruit trees, fruit vegetables, sugar beets, or flower buds, which circulates and dissipates the heating medium heated by sunlight to the farm ground in the facility, thereby adding agricultural facilities that can be forcibly cultivated pollution-free and safely. It relates to a temperature device.

Conventional technology

Nowadays, with the liberalization of agricultural products, a wide variety of agricultural products exceeding seasonality have been imported, and buyers can purchase rare, high-quality and highly safe agricultural products that are imported at an early stage against the background of computerization. It is changing to the consumption mode of purchasing selectively.
In order to cope with this situation, in Japan, when growing fruit trees, fruit vegetables, side dishes, or flower buds, etc., we plan to construct greenhouses and houses, etc. A shift to high-priced production is being actively promoted.

By the way, the current heating device is used even when the facility itself is a relatively small facility such as fruit vegetables and sugar beet, and the farmland area of the facility is about 300 to 600 m ² or more, and the tree height is high like a fruit tree cultivation facility. The capacity of the facility will be enormous.
For this reason, in order to warm the inside of such a facility, the heavy oil burner is burned exclusively and the high-temperature combustion air is blown and diffused into the facility, but the vast facility is heated to the required temperature. However, it is necessary to blow and diffuse a large amount of extremely high-temperature combustion air, which not only imposes great fuel economy, but even if a large amount of high-temperature combustion air is blown and diffused, the heated and heated air rises in the facility. Due to the residence, a significant temperature gradient is generated in the facility, and especially for fruit trees with high tree height, it is not only exposed to excessive heating, but also the heating effect of the farmland temperature, which is important for accelerated heating cultivation in the cold season, is remarkably lacking. Have a problem to do.

  In addition, what is important is that the high-temperature combustion air that is blown and diffused along with the combustion of a large amount of heavy oil contains a large amount of COx and NOx as harmful combustion gases. It has been pointed out that there is a danger of hindering the health of cultivating workers, and especially in recent years, it has been clarified that a large amount of extremely toxic dioxins are generated from heavy oil burners and combustion incinerators. The use of heavy oil burners entails the risk of serious consequences such as the inability to grow due to contamination of the farmland in the facility by dioxins and further absorption or attachment to the cultivated crops.

  In view of this situation, the inventor has conducted research, and as a result, a pigment capable of storing a heating medium having a required capacity in a reflection condensing part of a light receiving reflector that receives and reflects sunlight, and can absorb a wide wavelength range of sunlight. A storage tank formed of a material mixed with a pigment or coated with a paint mixed with the pigment, a supply pump and a supply pipe for supplying a heating medium to one side of the storage tank, and the other side Circulates and circulates the heating medium heated by a solar heater equipped with a delivery pipe and a solenoid valve for delivering the heating medium through the radiating unit installed in the horticultural facility. We have invented a heating device and a heating method for a horticultural facility for heating a horticultural facility and have already filed an application as Japanese Patent Application No. 2002-383522.

  However, the agricultural facilities that promote heating by heating as in the present invention are mainly required in cold regions in winter, but on the other hand, in cold regions, the outside air temperature is low and in winter, it is caused by cloudfall or cloudy weather. The solar warmer that heats by simply storing the heating medium in the reflection condensing part of the light receiving reflection plate according to the prior application of the inventor according to the inventor's prior application is at most 30 to 40 ° C. even in fine weather. The warming medium is only moderately warmed, and the warmed warming medium is also easily cooled at a low external temperature, so even if it is circulated as it is, it will have a sufficient effect on warming in the facility. Can not.

  For this reason, although the heating medium heated by the solar heater is further provided with a heating control tank and heated and circulated, it is common to reheat the heating control tank. Although a heating heater using electric power or solar power generation power is used, the heating heater consumes a large amount of power, so that it still causes an increase in maintenance costs and solar power generation supplies such a huge amount of power. In addition, a large number of solar cell panels are deployed over a large area, and an extremely large capacity storage battery is required, resulting in a huge equipment cost.

  Therefore, as a result of further research, the inventor arranged the cross-sectional area of the heating tube for heating the heating medium in the solar warmer to be small and dense, and was arranged at this high density. A casing and a light-transmitting casing, in which sunlight is reflected and concentrated on the heating tube with a sufficient light collection area, and the heating medium in the heated heating tube forms a solar heater. By providing heat insulation means so as not to dissipate from the lid, it can be used as an extremely high temperature heating medium, and this high temperature heating medium is stored in a storage tank. By transporting the heat dissipating mat into the heat dissipating mat and dissipating the heat, it was investigated that the facility can be sufficiently heated even in cold weather conditions with few sunny days and sunshine hours.

Problems to be solved by the invention

  The present invention provides a high-temperature heating medium even in cold weather conditions with little sunlight, and transports this heating medium into a heat dissipating mat connected to the farm ground to circulate and dissipate it. Another object of the present invention is to provide a warming device for an agricultural facility that can warm the agricultural facility at a low maintenance cost and enable forcing cultivation.

Means for solving the problem

  The means used by the present invention in order to solve the above-mentioned problem is that the both sides of the inside of the casing having the required area and having the opening at the upper part are set up facing the sunlight outside the agricultural facility. Heating tubes that are alternately bent and densely parallel at a predetermined interval and whose edges extend to the outside of the casing are arranged, and the dense and parallel heating tubes are arranged. In order to heat and warm the heating medium in the heating tube to a high temperature by sufficiently reflecting and concentrating the sunlight below, the cross-section is semi-arc, especially a semicircular arc shape with respect to the diameter of the heating tube A large number of reflector plates whose diameters are at least 6 times and whose inner surfaces are mirror-finished are integrally arranged.

  The reflected and condensed heat from the semicircular arc shaped reflector is not leaked to the outside, and then the reflector is closely fixed in the casing by a highly heat insulating member made of a synthetic resin material, and sunlight is incident. The opening of the casing to be sealed is hermetically sealed with a translucent lid made of double-glazed glass in which a vacuum or an inert gas is sealed, thereby forming a solar warmer.

  In addition, a storage tank for keeping heat and adjusting the flow rate to circulate and dissipate the heating medium heated to a high temperature by such a solar heater, and appropriate for radiating and heating facility farm ground by circulating heat. In order to adjust the heat dissipation temperature to a suitable level, a water supply solenoid valve that freely adjusts the amount of water supplied from the water supply pipe by a temperature sensor and a heating medium adjusted to an appropriate heat dissipation temperature are laid on the farm ground as appropriate. A transfer pipe composed of a transfer pump for transferring to the heat dissipating mat body and a transfer pipe is provided.

  In addition, the heat dissipating mat body that heats and heats the facility farm ground by transporting and circulating the heating medium transferred by the transfer pipe is a synthetic resin thin wall having a required diameter on a support material of a required size made of a synthetic resin film. The heat radiating pipe made of a tube is bent alternately on both sides and joined and fixed to one side of the support material in parallel at a predetermined interval, and the heat radiating mat members are connected to each other in an appropriate number and radiated. The end edge of the tube is extended to the outer side of the support material and on the opposite side surface.

  The rear end portion of the heat dissipating mat body is used to heat the circulating medium that has been circulated and radiated through the heat dissipating mat body connected in an appropriate number to the high temperature or to be returned to the storage tank and to circulate and dissipate heat. The present invention resides in a heating apparatus for an agricultural facility having a configuration in which heat is circulated through a reflux pump, a shunt solenoid valve, and a reflux pipe including a reflux pipe.

Action

  The present invention uses the technical means as described above, and a solar heater is installed outside the agricultural facility so as to face the irradiation direction of sunlight and protects the outside of the casing. Inside, the heating tube that heats the medium by flowing into the inside is bent at both sides alternately and densely arranged in parallel at a predetermined interval, and the edges extend outward from the casing. In addition, sunlight is reflected and concentrated below the heating tube to warm the heating tube and the heating medium flowing into the heating tube to a high temperature. A large number of reflector plates that reflect and condense sunlight over a wide area with a ratio of the diameter of the semicircular arc reflector plate 6 times or more of the diameter of the arc-shaped reflector plate, particularly the heating tube. Since the heating tube is condensed and heated with a high degree of reflection and concentration, the heating medium is also extremely poled. Warms to a high temperature Te.

  In addition, a large number of integrally arranged reflectors are closely fixed to the casing by a highly heat insulating member made of a synthetic resin material, and the inside of the casing is filled with vacuum or inert gas. Since it is sealed with a translucent lid made of multi-layered glass, the heated tube and the heating medium that are heated to a high temperature by reflecting and condensing sunlight with a high degree of reflection and collection, and the vicinity of The heated air is prevented from radiating or leaking out of the cold casing, and a warming medium heated to a high temperature for a long time is obtained.

In the present invention, a sufficiently high temperature heating medium can be obtained by the solar heater, so that general electric power and a solar power generation device for reheating the heating medium are unnecessary, and this high temperature medium is used. The temperature heating medium can be temporarily stored in the storage tank to adjust the flow rate during circulation heat dissipation, and the amount of water supplied from the water supply pipe can be freely adjusted by the temperature sensor in order to adjust the temperature to an appropriate temperature for circulation heat dissipation. It can be transferred and circulated to the heat dissipating mat body by a simple transfer pipe composed of a water supply solenoid valve and a transfer pipe to be transferred, and heat radiation and heating of the agricultural facility farm ground are performed.
However, when the farm ground of the agricultural facility is heated by heat radiation from the heating medium transported and circulated in the heat radiating mat, the air heated by the heating is heated while rising throughout the agricultural facility. Since the temperature is set, the entire facility is heated substantially evenly.

  Furthermore, in the present invention, since a warming medium heated to a high temperature is obtained, the residual heat is also retained in the warming medium that has been transported and circulated through the heat dissipating mat, so that it is stored by the reflux pump. By recirculating to a tank, it can be used repeatedly for heat dissipation, or by recirculating to a solar warmer, a warming medium heated to a high temperature can be easily obtained even under cold conditions with little sunlight. .

  Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic explanatory view of the present invention, FIG. 2 is a front view of a solar warmer, and FIG. 3 is a cross-sectional explanatory view of the solar warmer. The solar warmer 1 is erected outside the agricultural facility 2 so as to face the irradiation direction of sunlight, and naturally the position where the solar warmer 1 is erected is sunshine. Since it is important not to be blocked, depending on the situation of the installation location, the installation tower 1A is formed and installed at a relatively high position.

  As shown in FIG. 2 and FIG. 3, the solar warmer 1 is erected outside the agricultural facility 2 and used as an outer frame of the solar warmer 1. The casing 1B is always exposed to sunlight, wind and rain, or weather conditions with severe temperature differences, or has durability and weather resistance that can withstand the impact of flying objects. Since a material that does not dissipate reflected and condensed heat generated by sunlight is convenient, a polycarbonate resin, a polyurethane resin, an ABS resin, or the like is used as a specific material.

  The casing 1B is usually formed in a square or rectangular shape having a required area and an opening 1C on the upper surface, and a relatively shallow bottom box. Both sides of the casing 1B are alternately arranged in the casing 1B. And a heating tube 1D in which an injection part 1E and an extraction part 1F are extended to the outside of the casing 1B are provided at the edges thereof. . There are no particular restrictions on the material of the heating tube 1D in such a case, but the heating medium 3 flows into the inside and heats up to a high temperature, so that heat resistance and toughness are maintained and heat conduction is achieved. In particular, a copper tube material, a stainless steel tube material, an aluminum tube material, or the like is used, and more preferably, short wavelength light (UV or UV) in the solar radiation (radiation) spectrum in the reflection and collection of sunlight. It is also proposed to apply a light selective absorption paint or a solar light absorption paint in order to absorb VIS) and have a large heat conversion capacity and to reduce a heat radiation (radiation) loss.

Below the heating tube 1D thus arranged, a reflecting plate 1G having a semicircular cross section and mirror-finished inner surface for reflecting and concentrating sunlight is connected to the heating tube 1D. Many are coordinated so as to enclose.
This reflector 1G efficiently reflects and condenses the received sunlight to heat the heating tube 1D to a high temperature, and its inner surface is mirror-finished by aluminum plating or the like. In order to heat the heated tube 1D to a higher temperature by increasing the reflected light collection degree, the diameter of the semicircular reflector plate 1G is 6 times or more the diameter of the heated tube 1D. Those having a reflective condensing area of 2 are preferable.

In such a case, if the diameter of the heating tube 1D is made too thin, not only the flow of the heating medium 3 flowing into the heating tube 1D is inhibited, but also the heating amount of the heating medium 3 to be heated is reduced. Even a thin one is desired to be 10 mm or more, preferably about 20 to 60 mm.
In addition, the heating medium 3 used in the present invention is not particularly limited, and usually water is used.

The reflecting plate body 1G formed and coordinated in this way is tightly fixed in the casing 1B by a highly heat insulating member 1H made of a synthetic resin material.
That is, since the solar warmer 1 is erected outside the agricultural facility 2 under cold weather conditions, sunlight is efficiently reflected and condensed by the reflector 1G in the casing 1B to increase the temperature. When the heating tube 1D is heated or the air in the vicinity is sufficiently heated, a large difference from the external temperature is generated, and the heated heat is easily dissipated or leaked.
For this reason, in order to prevent the dissipation and leakage of the heated heat, a highly heat-insulating member that uses a synthetic resin material that has high heat insulation and excellent workability as a material to be used and that has been further provided with a heat insulation function Specific examples of highly heat-insulating member 1H are polycarbonate, polyurethane, polyamide, polyester, or ABS resin material foamed by 3 to 10 times closed cells, or artificial zeolite or natural material. Examples thereof include those in which inorganic porous powders such as zeolite and pearlite are blended at a weight ratio of approximately 15 to 30%.

Further, in the opening 1C of the casing 1B, sunlight is effectively transmitted on one side, and is efficiently reflected and collected by the reflector 1G, and the heating tube 1D is heated to a high temperature by the reflected collection or in the vicinity thereof. The air is heated, and the heated heat is dissipated to the outside or sealed by the translucent lid 1K so as not to leak out.
The translucent lid 1K is made of glass plate 10K because it effectively transmits sunlight, and is strong and excellent in weather resistance and cold resistance. From the necessity of preventing leakage, the two glass plates 10K are arranged around the periphery of the glass plate material 10K through a separator 11K with a required interval to form a double-glazed glass 12K. Or an inert gas such as argon gas, xenon gas, or krypton gas is enclosed.

  The heating medium 3 heated to a high temperature by the solar heater 1 thus configured is transferred through the heat dissipating mat body 5 connected and laid in a required area on the farm ground 2A in the agricultural facility 2. In order to increase the temperature by circulating and radiating heat, the temperature can be maintained as shown in FIG. 4 and stored in the storage tank 4A for adjusting the flow rate, and the heating medium 3 stored in the storage tank 4A is stored in the storage tank 4A. In order to adjust the heat radiation temperature to heat the farm ground 2A by circulating heat and to circulate heat, a water supply electromagnetic valve 4D that can freely adjust the amount of water supplied from the water supply pipe 4C by the temperature sensor 4B is provided. A transfer line 4 is formed by a transfer pump 4E for transferring the heating medium 3 adjusted to a required circulating heat dissipation temperature to the heat dissipating mat body 5 and a transfer pipe 4F.

In this case, the temperature of the heating medium 3 of the solar warmer 1 varies depending on the sunshine time, the intensity of sunlight, the design specifications of the solar warmer 1, the external temperature difference, and the like. The temperature of the heated heating medium 3 to be circulated and radiated varies depending on the heating conditions in the agricultural facility 2, the type of crops, the outside temperature, etc. Since it is sufficient to circulate and dissipate heat at about 30 to 50 ° C., it is sufficient to mix and transfer the water supply temperature and the amount of water supplied to the heating medium 3 of the storage tank 4A so that the temperature is adjusted. good.
Desirably, the heat of the heating medium 3 heated by the solar heater 1 is transferred to the heat dissipating mat body 5 without being dissipated as much as possible, and the heating in the farm ground 2A and the farm facility 2 is effective. Therefore, it is advantageous to cover or coat the outer surface of the storage tank 4A, the transfer pipe 4F, or the reflux pipe 6B of the transfer pipe with a heat insulating material 4G.

The heating medium 3 transported with the required circulation heat radiation temperature and flow rate in the transfer pipe 4 is transported and circulated through the heat dissipating mat body 5 connected to the farm ground 2A in a required area. Warming is done.
As shown in FIG. 5, the heat dissipating mat body 5 has a heat dissipating pipe 5B made of a synthetic resin thin-walled tube having a required diameter alternately bent on one side surface of a support material 5A made of a synthetic resin film. And it is arranged in parallel with a predetermined interval and is joined and fixed 5C, and the edge of the heat radiating pipe 5B is connected to the side opposite to the outside of the support member 5A. The reason is that a flexible material such as a synthetic resin film is used for the support material 5A in such a case. The farm ground 2A to which the heat dissipating mat body 5 is connected and laid is generally undulated. Therefore, it is preferable to closely heat and dissipate heat corresponding to the ups and downs of the farm ground 2A when connecting and laying. Furthermore, since the synthetic resin thin-walled tube material is used for the heat radiating pipe 5B, the laying area of the heat radiating mat body 5 to be connected and laid covers a wide area, so that rapid heating of the transported heating medium 3 is prevented, This is because the heating medium 3 that has been sufficiently heated is transferred to the entire farm ground 2A and is circulated and radiated to allow the heating.

Furthermore, there is no particular restriction on the joint fixing 5C between the support member 5A and the heat radiating tube 5B, but welding with a welder is extremely advantageous in terms of workability.
In addition, there is no special restriction on the size and shape of the support material 5A that determines the size of the heat dissipating mat body 5, but a very large number of connecting operations are required if it is too small to connect and lay on the vast farm ground 2A. As a result, it is desirable that the width is at least 90 cm and the length is 180 cm or more, and that the overall shape is square or rectangular in order to connect and lay each other, and the diameter of the heat radiating tube 5B is too small. If it is thin, the transfer circulation of the heating medium 3 is hindered, or the flow resistance accompanying the transfer increases, and a high-pressure transfer pump 4E is required.

  There is no particular restriction on the connection and laying of the heat dissipating mat body 5, and it is sufficient that the heating medium 3 is connected so as to be transported and circulated through the heat dissipating mat body 5. As a simple means, as shown in FIG. The connecting edges 5D extended to the respective heat dissipating mat bodies 5 are arranged close to each other at the required positions on the farm ground 2A, and the adjacent connecting edges 5D, 5D are connected to the connecting edges 5D, 5D. This can be achieved by alternately communicating with the communication pipes 5E and 5E that can be fitted into the pipe and maintain flexibility.

In such a case, when mainly heating the farm ground 2A, the heat dissipated from the heat radiating pipe 5B is laid by placing the support material 5A of the heat radiating mat body 5 on the upper side as shown in FIG. Stays in the gap between the farm ground 2A and the support material 5A, and the heating of the farm ground 2A is promoted. On the other hand, when the heating in the agricultural facility 2 is mainly used, the heat radiating pipe 5B is on the upper side. Convenient to do.
Further, especially in the cold weather conditions and when the area where the connection is laid is also a wide area, the circulation heat radiation distance of the heating medium 3 becomes long, so that excessive heat radiation from the heat dissipating mat body 5 is suppressed and the farm ground 2A. And from the viewpoint of heating the entire agricultural facility 2, it is desirable to use the heat dissipating mat body 5 in which the support material 5A is bonded and fixed 5C on both sides with the heat dissipating pipe 5B interposed therebetween as shown in FIG.

  The heating medium 3 circulated and radiated without being transferred through the heat radiating mat body 5 thus connected and laid is used in the solar warmer 1 or when a sufficient amount of residual heat is held when reheating is required. In order to recirculate to the storage tank 4A and recirculate heat, it is configured to recirculate by a recirculation pipe 6 comprising a recirculation pump 6A, a diverting electromagnetic valve 6B and a recirculation pipe 6C.

The invention's effect

  In the present invention, as described above, the solar warmer is erected outside the agricultural facility so as to face the irradiation direction of sunlight, and both sides thereof are alternately bent in the casing so as to be parallel to each other at a predetermined interval. The heating tube is densely arranged in a shape, and its edge extends out of the casing as an injection part and a pouring part, and further, sunlight is reflected and concentrated below the heating tube to In order to heat the heated tube, the cross section is a semicircular arc shape and the inner surface is mirror-finished. In particular, the reflection plate having a semicircular arc shaped reflector plate with a diameter of 6 times or more of the diameter of the heated tube. A reflector plate having a large light area is integrally arranged. The reflector plate is closely fixed to the casing by a high heat insulating member, and the opening of the casing is made of double-glazed glass. Because it is sealed with a translucent lid filled with active gas, it is cold and has little sunlight Even under elephant conditions, the heated tube body is heated with a high degree of reflection and concentration, and the heated tube body and the nearby heated heat are not dissipated or leaked, resulting in an extremely high temperature heating medium. .

Since the heating medium is obtained at a high temperature, the heating medium is stored in a storage tank, and the amount of water supplied from the water supply pipe is adjusted by a water supply electromagnetic valve, and a transfer pipe consisting of a transfer pump and a transfer pipe is used. The heating medium that is adjusted to the proper transfer amount and temperature, because the proper transfer amount for circulating heat and the heating medium adjusted to the appropriate temperature can be provided, and the power and equipment for reheating are not required. However, a support material made of a synthetic resin film of the required size and shape is bonded and fixed to one or both sides thereof, and a heat radiating tube made of a synthetic resin thin tube material is bent alternately on both sides to be parallel to a predetermined interval. The heat dissipating mat inside the heat dissipating mat connected to the farm ground with the required area is circulated and heat is dissipated, so that the heat dissipating mat is laid in close contact with the farm ground and has the lowest temperature in the agricultural facility. Heat radiation from the farm ground Thus also becomes possible to air heated to warm the entire elevated agricultural facility, Agriculture facility warmed by drives out substantially uniform temperature.
In addition, the present invention warms the agricultural facilities by radiating heat from the heating medium by sunlight, so that the agricultural facilities are kept clean, the cultivation operator can work safely, and the cultivation crops are completely dangerous. This is a heating device for agricultural facilities that has many features, such as being extremely low in maintenance cost.
