Description

  The present invention relates to a centrifugal spray apparatus that eliminates temperature and humidity deviations by cooling or humidifying a building such as a house, a livestock barn, or a factory, and contributes to an improvement in the environment for growing crops and livestock, and the working environment.

  Recently, it is useful to grow greenhouses such as plastic houses for the purpose of cultivating crops or raising livestock and harvesting foods that people want throughout the year without being affected by the weather and weather conditions. It has been. However, since these houses are almost sealed spaces without ventilation or circulation of outside air and / or inside air unless a ventilation fan and circulation fan are installed on the ceiling and wife surfaces, they grow in house cultivation. The crops that were made were susceptible to epidemics. Furthermore, in a barn, since the inside of the barn cannot be sufficiently ventilated, poultry such as pigs, cattle, and chickens raised in the barn are easily affected by disease, and improvement of the growth environment has been demanded.

  Furthermore, depending on the type of crop, due to temperature and humidity deviations, the crop may condense, causing leaf leaf disease, plague, etc., reducing the yield, making it impossible to harvest good quality crops, and causing pests. There was a problem that the efficiency of house cultivation could not be achieved.

  In the same way as described above, if the factory occupies a large area in the factory, only the cooling equipment provided in the factory cannot be sufficiently cooled, which is harsh for the operator and is frequently occurring recently. There has been a demand for a safe working environment due to the occurrence of heat stroke and other diseases.

  Therefore, as means for solving such a problem, as in the present invention, an apparatus or method for spraying fine mist and / or mist has been disclosed. Are exemplified below.

  First, as a prior document cited first (referred to as Document 1), there is a “humidifier” of JP-A No. 2001-141288. The outline is that the air sucked through the suction port by the blower fan is discharged to the discharge port, a casing having a water tank in which humidifying water is stored below the blower fan, and the water tank A rectangular water ejection groove formed between a pump for forcibly feeding water into a water pipe and a casing inlet and outlet and connected to an electric motor to rotate and radially radiate from the center of this blower fan A rotating body that ejects water supplied from a water pipe in the form of particles, and an outer peripheral edge of the rotating body, and a plurality of slit grooves are formed in the circumferential direction to cover one side of the motor It is intended to provide an integrated structure that can be moved freely, improving the workability of inspection and maintenance.

  Next, as a second prior art document (referred to as Document 2), there is "Mist fan and mist fan kit" of utility model registration No. 3068525. In this outline, the mist fan is provided with a ring-shaped liquid feed pipe having four jet outlets in a size corresponding to the blade diameter of the blower fan on the front surface of the blower fan frame provided with the blower fan. Water supplied with a predetermined pressure (1 kgf / cm 2 to 8 kgf / cm 2) is supplied from a water supply port provided in the liquid pipe, and the air fan is rotated so that the air pressure is sprayed from the outlet. Mist water is diffused in the greenhouse and the inside of the greenhouse is cooled by the latent heat of vaporization of the mist. And, as shown in the figure, this mist fan has a structure in which a water receiver is installed below the mist fan so that water droplets condensed in the liquid supply pipe are received below. The mist sprayed from the spout provided in the liquid supply pipe is diffused into the greenhouse, greenhouse or barn by supplying the pressure above a certain level and operating the blower fan. It is intended to perform disinfection and cooling by latent heat of vaporization in a greenhouse or barn.

  Finally, as the third prior art document (referred to as reference 3), there is "Spraying device and spraying method" of the most published 1998-05432. In this outline, an impeller having a structure in which a plurality of blades extending in the outer peripheral direction from the center are sandwiched between opposed disks arranged to face each other, and an opening for water supply is formed in the center thereof. . Further, a plurality of baffle members are arranged in the space between the opposing disks so that the water flowing in from the water supply opening collides, and is used for a plastic house, a greenhouse, a livestock barn, a crop, etc. With regard to a spraying device and a spraying method suitable for performing a large amount of spraying, it is intended to generate a large amount of fine mist with a simple device so that it can be spread over a wide area.

JP 2001-141288 A Utility model registration No. 3068525 Republished 1998-05432

  Document (1) is a configuration in which water for humidification is pumped from a water tank and the water is ejected in the form of particles from the ejection groove. On this configuration, the particles ejected from the ejection groove are coarse ( It is considered that large particles are generated). The problem with the generation of large particles is that if they are large particles, the large particles will not scatter far away unless the rotational speed of the rotating plate is increased or the air flow rate is increased. Even if the amount of large particles that were not increased increases, even if the amount of water is pumped from a certain amount of pump, the leakage of the amount of water is wasted, and this leakage causes wetting to crops or livestock due to drops of large particles, resulting in the occurrence of disease. In addition, the large particles cannot be atomized (scattered by fine particles), resulting in secondary problems such as the fine fog cooling and humidification effect intended by the apparatus, and a chemical solution failure. By using this apparatus, it may take time and effort to achieve its original purpose, and problems such as inability to efficiently perform fine mist and spraying are pointed out.

  Next, the document (2) is a configuration in which a ring-shaped liquid feeding pipe having four jet nozzles is installed on the front surface of the blower fan frame, and water is sprayed from the jet nozzle. Since the shape of the jet port is large, it is considered that the same problem as in the literature (1) occurs. In addition, since the four jet outlets are provided in a dispersed manner, water is not sprayed from other than the jet outlet of the liquid feeding pipe. Even if the amount of air blown from the blower is increased, it is not sprayed far away, and when it is intended to capture dust, the above-mentioned spraying ability cannot be expected to have a sufficient effect. It is necessary to install a large number of units, which causes problems such as complicated maintenance, troublesome management, and increased operating costs.

  Finally, although the structure of Document (3) is different from Document (1) and Document (2), large particles are generated as in Document (1), and it is considered that the above-described problems occur.

Therefore, the present invention has the following effects in order to solve the above problems.
(B) The rotating plate and the ridges and / or the through holes function as an eliminator, and by generating these fine particles, the fine particles can be sprayed and / or diffused (scattered) far away, and scattered by the rotation of the rotating plate. It becomes possible to reach the distant fine particles far away, reduce water and / or energy resources, and reduce water and / or air pumping loss, thereby saving energy.
(B) Prevents dripping of water droplets from the tip side of each part, prevents wetting of crops or livestock, machine parts, human bodies, etc., prevents deterioration of quality, and diseases caused by wetting, and is also safe for workers A safe working and / or working environment.
(C) The fine fog cooling and the humidification effect can avoid and prevent secondary problems due to chemical damage, etc., and the fine fog and spray can be efficiently applied to crops or livestock, machine parts, human bodies, etc. There are real benefits such as being able to.
(D) In addition, by dispersing fine particles far away, improving the growth environment through improved heat retention and breathability, etc., it is possible to provide high quality crops (livestock products), Expansion can be achieved.
(E) Furthermore, it is possible to disperse far away, for example, because the number of installed units can be reduced, maintenance and other management are simplified and simplified, and running costs and energy resources are reduced and facilitated. Can contribute to the maintenance of the environment.

FIG. 5 is a side view of FIG. 1, FIG. 6 is a first reference diagram showing a use state, and FIG. 7 is a second reference view showing a use state.

Therefore, the main part and / or the operation of the preferred embodiment of the present invention are segmented, and the following configurations will be described in accordance with the segments.
(1) Centrifugal atomizing device.
(2) A rotating plate.
(3) An annular body.
(4) It is description of the flow of a centrifugal atomizing device.
(5) Other configurations.

(1) Regarding the explanation of the centrifugal fogging device,
The centrifugal atomizing device 1 will be described with reference to FIG. The centrifugal atomizing device 1 has a structure in which an open-type substantially cylindrical casing 2 is used as an outer body, and one end 2a of the casing 2 is a suction port 3 and the other end 2b is a discharge port 4.

  And the inside of the one end 2a of this casing 2 is provided with the rotary blade 6 for ventilation means. The rotary blade 6 is pivotally supported on an output shaft 7 of a motor 8 housed in the casing 2, so that the rotation of the motor 8 causes the rotary blade 6 and the output shaft 7 to rotate at a predetermined rotational speed. The air is blown toward the other end 2b (discharge port 4). That is, the rotary blade 6 has a structure that sucks and blows in and / or circulates the inside air and / or outside air that stays or circulates in the building A (hereinafter referred to as the building A) such as a house, a livestock barn, or a factory. Therefore, as long as this purpose is achieved, the shape, the number, the mounting position, and the like of the rotary blade 6 are not limited. There is a gap between the inner peripheral surface of the casing 2 of the rotary blade 6.

  On the other hand, inside the other end 2 b of the casing 2, a cylinder 10 for spraying means is provided with a gap from the inner surface of the casing 2. The gap serves as a wind passage for the wind generated by the rotary blade 6. In addition, an annular body 11 is provided on the inner surface of the base body 10a (motor side) of the cylinder body 10 with a predetermined interval on the inner surface thereof. The annular body 11 has a width of approximately half the width of the cylindrical body 10 in the axial direction (X direction), thereby forming a band-shaped annular body portion 10c on the free end side 10b of the cylindrical body 10. To do. The ring body portion 10c has a structure for receiving a water drop (a structure useful for water recovery) that secures a place for installing a hose, which will be described later, and even if a water drop from a rotating plate, which will be described later, hangs down. Avoid the harmful effects that occur. An inner flange piece provided at the rear end of the cylindrical body 10 is attached with an inner flange piece at the rear end of the annular body 11, both are integrated via a screw 14, and a gap is formed between the two. The rear end of the cylindrical body 10 is supported by the motor 8 via a rear plate 1000 provided in the radial direction on the outer periphery of the motor case 8000 (or the motor 8 is possible), and between the inner surface of the casing 2. It is a structure that is installed at intervals.

  Further, the annular body 11 is internally provided with a disk (shallow dish) -shaped rotating plate 12 which is provided with irregularities at intervals from the inner surface thereof. The rear end of the rotating plate 12 is covered with the rear plate 1000, and the rotating plate 12 is fixed to an output shaft 13a of a motor 13 provided in the motor case 8000 (the casing 2 is also possible). . Therefore, the rotating plate 12 rotates at an appropriate number of rotations through the rotation of the motor 13. In addition, the disk-shaped uneven strip of the rotating plate 12 captures the water supplied from the water supply means on its wide surface and secures a residence time, and reliably flows the water to the end in the radial direction. It is provided to do. In addition, the strength can be improved and / or the thickness can be reduced. And the shape and / or number of this uneven | corrugated strip are not limited.

(2) Regarding the explanation of the rotating plate,
The center boss portion of the rotating plate 12 is supported by the output shaft 13a of the motor 13 and rotates by the operation of the motor 13 as described above. The rotating body 12 has a diameter that can be housed in the annular body 11 and rotates smoothly and without blind movement without contacting the annular body 11. Efficient use or avoidance of wind pressure loss can be achieved.

  The rotating plate 12 is provided with an opening of a hose 21 adjacent to supply water. The lower end of the hose 21 is in a tank 20 for storing water, and the tank 20 is attached to the lower portion of the casing 2 or is placed separately. In order to adjust the amount of water stored in the tank 20 as appropriate, a water level sensor 22 is provided in the tank 20. Although not shown in the drawings, the water level sensor 22 plays a role of adjusting the supply or stop of water at any time from a water supply facility such as a water supply in a configuration example in which a solenoid valve is provided. In the figure, reference numeral 23 denotes a supply port for supplying water from a water supply facility such as a water supply. And 25 is a pump, and it conveys the water supplied from the said supply port 23 at any time.

  Reference numeral 24 denotes an adjustment valve that is attached to or separately from the casing 2 in order to adjust the spray amount. The adjustment valve 24 has a structure in which the amount of spray is reduced by rotating forward and the amount of spray is increased by reversing.

(3) Regarding the explanation of the annular body,
As described above, the annular body 11 has a structure in which the base end side 11a of the annular body 11 is closed via the rear plate 1000 and the free end side 11b thereof is open. The annular body 11 has a large number of protrusions 110 in the axial direction at a substantially central position (approximately one-half of the axial direction) from the base end side 11a in the axial direction (length of the cylindrical body). Is formed. The end of the protrusion 110 is configured to be located in the vicinity of the annular end of the rotating plate 12. In addition, since this protrusion 110 perforates the said annular body 11 and makes it stand in the axial direction, the through-hole 111 which provided the space | interval suitably was formed in the annular body 11. FIG. As other structures, in principle, the shapes of the protrusions 110 and the through holes 111 are not limited. This is because the protrusion 110 and the through-hole 111 function as an eliminator, so it is necessary for water to collide with the protrusion 110 and become fine particles, and the shape is scattered from the rotating plate 12. A shape that is likely to collide is desirable. And in the structure which press-molds this protrusion 110, the through-hole 111 becomes a similar shape to the protrusion 110. FIG. In addition, a belt ring portion 112 is provided at a portion where the protrusion 110 and the through hole 111 are not provided at a substantially central position (approximately one half of the axial direction) from the free end side 11b of the annular body 11. The belt ring portion 112 guides water that has not been scattered and / or sprayed through the protrusion 110 and the through hole 111 to the water recovery hole 100 provided in the lower end portion of the cylindrical body 10. It plays the role of water supply. With this structure, the flow of water (flow of water droplets) from the annular body 11 to the cylindrical body 10 and prevention of water droplet scattering are achieved.

  And in order to make the belt ring part 112 play a role as a water supply, the surface of the annular body 11 and / or a large number of protrusions 110 is subjected to processing such as pear ground (shot blasting) processing, electric decoration processing, etc. A fine uneven shape is formed on the surface. In this uneven shape, water diffused or scattered (sprayed) by the rotation of the rotating plate 12 collides with the ridge 110 and becomes fine particles. The fine particles are formed so as to remain on the surface of the annular body 11 and / or the protrusion 110, and the structure ensures the fine particles through the uneven shape. That is, the surface tension of the fine particles prevents the particles from becoming spherical and makes it easy to remain on the surface. This residual effect eliminates the generation of water droplets, eliminates the scattering thereof, eliminates dripping of water, eliminates the above-mentioned problems associated with them, makes effective use of water, and ensures energy saving. it can.

  In addition, the pear-skin (shot blasting) process and the electric decoration process are not limited to the surface of the annular body 11 and the surface of the ridge 110. The processing of.

(4) Regarding the explanation of the flow in the remote spray device,
Since the structure of this far spray apparatus has been described in detail, the flow of water and wind of this far spray apparatus will be described below.

  First, the inside air and / or outside air of the building A sucked by the suction of the rotary blade 6 is forwarded from the suction port 3 of the casing 2 toward the discharge port 4.

  Further, water pumped from the tank 20 through the hose 21 is scattered by the rotation (centrifugal force) of the rotating plate 12. Due to this scattering, water collides with a large number of protrusions 110 or through-holes 111 provided on the annular body 11, and as a eliminator, the total particles are refined to form fine particles.

  The fine particles thus formed remain on the belt ring portion 112 due to the uneven shape processed on the surface, and are blown from the discharge port 4 by the blowing. The water or large particles (which are larger than the fine particles) that could not be sent out by the air flow flow through the belt ring portion 112 and flow into the recovery hole 100 for water recovery provided in the lower part of the cylindrical body 10. . The water flowing into the recovery hole 100 is stored in the tank 20 and reused as spraying means. The water flowing through the belt ring portion 112 has a structure that also flows into the cylinder 10, and when a large amount of water flows, there is a risk that the water will flow out of the cylinder 10. Therefore, the prevention wall 101 for preventing water leakage is installed at the lower end of the cylinder 10 on the open side. Therefore, water is smoothly recovered from the cylindrical body 10 by the recovery hole 100 without overflowing to the outside. In addition, by installing this prevention wall 101, when the amount of water is pumped from a fixed amount pump, waste of the amount of water does not occur, effective use of water, and securing of energy saving can be achieved. Note that the prevention wall 101 can be formed by slightly bending both ends thereof to efficiently collect the dripping of water droplets, and the recovery rate of water to the recovery hole 100 is improved.

(5) Regarding the explanation of other configurations,
The casing 2 is provided with a plurality of locking members 41 for locking the hanger 40 at the upper portion thereof, and can be installed in the position and orientation desired by the operator in the building A via the locking members 41. It becomes possible.

  Further, by changing the length of the hanger 40, the centrifugal fogging device 1 can also adjust the depression angle from the horizontal state. By making it possible to adjust the depression angle, it is possible to directly humidify and cool the crops, and by spraying fine particles far away, the growth environment such as heat retention and air permeability is improved, and the quality is improved. Crop can be provided and crop yield can be expanded. However, the depression width is not limited because water may overflow from the belt ring portion 112 serving as a water flow path. In order to prevent this overflow of water, a structure in which the height, size, and shape of the prevention wall 101 are changed can be considered. However, a loss of wind pressure due to air blowing, and fine particles collide with the prevention wall 101. Must also be considered.
