Abstract

PURPOSE:To make stable supply and sublimation of metal aldehyde uninhabitedly possible by a method wherein metal aldehyde fed from a feeder is averaged by blade plates for agitation under being scattered with a blower, sublimated by heating, and made into powdered cotton-like material. CONSTITUTION:Metal aldehyde 4 as powdered raw meterial is fed into a feeder 5 and a heating plate 14 is heated by the electric flow in a heating device 17. The metal aldehyde 4 contained in supply blades 21 is fed to fall slowly into the corners of sublimation chamber 8 by the rotation of a supply motor 19 and falls down to the plate 14 placed at the bottom in such a condition that the material is nearly averaged by the operation of a blower 10 and is agitated by rotating blades 12 and sublimated by the heat of the plate 14. This sublimated metal aldehyde becomes vapor and is blown off into a room from a room inside discharge hole 9 as the metal aldehyde is being made into powdered cotton-like material.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for installing an air conditioner in a closed room and making it float in the closed room in order to visualize the airflow distribution of the air conditioner or the like. This relates to an aldehyde sublimation device.

Conventional technology Conventionally, in order to visualize the airflow distribution of air blown out from the outlet of an air conditioner, there was a method of checking the airflow using smoke such as dry ice or other smoke in addition to metaldehyde. However, since neither of them provides sufficient visibility, using sublimated metaldehyde allows for long-term visibility in conditions that are relatively similar to actual conditions. The easiest way to sublimate this metaldehyde is to place a container such as a frying pan on top of an electric heater, supply an appropriate amount of metaldehyde, stir it with a metal rod while heating, and the metaldehyde will sublimate. It turned into powder and flew up into the indoor air, filling the room in a floating state, and the airflow distribution of the air blown out from the air conditioner was visible.

Problems to be Solved by the Invention As described above, the conventional method of sublimating metaldehyde using a frying pan, etc., requires a person to stir it around, and therefore a gas mask is used to prevent inhaling the metaldehyde. However, there were some problems, such as inhalation and harm to health.

The present invention solves these problems, and aims to provide a metaldehyde sublimation device that can stably supply and sublimate metaldehyde unattended.

Means for Solving the Problem In order to solve this problem, the present invention provides a supply device for supplying metaldehyde to the main body, and a stirring blade plate for stirring the metaldehyde supplied from the supply device. A stirring motor provided, a heating device for sublimating the metaldehyde while stirring with the blade plate, and a blower for blowing the metaldehyde sublimated by the heating device and turned into powder into the room. It is.

Function: With this configuration, the metaldehyde supplied from the supply device is scattered by the blower and falls downward due to its own weight, being averaged by the stirring vanes, and is heated by the heating device, and this heating causes sublimation. Then, the sublimated metaldehyde powder is blown into the room using a blower, filling the room with the powder and making it float while the airflow distribution is visualized.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 4. In FIG. 4, a main body 1 serving as an outer can of the metaldehyde sublimation apparatus is configured in a rectangular box shape,
It is supported by leg 2. A cover plate 3 is provided on the top side of the main body 1 so as to cover the main body 1. Outside this substrate 3, there is a supply device 5 for introducing powdered metaldehyde 4 (FIG. 3) from above, a stirring device 7 for stirring the metaldehyde 4 with a stirring motor 6, and a sublimation chamber in the water body 1. 8 (Fig. 2), and then return to the indoor air outlet 9.
The room is equipped with a blower 10 for blowing powder of 1-metaldehyde 4 into the room.

In FIG. 1, the stirring motor 6 has a shaft 11 provided facing the sublimation chamber 8 below, and blade plates 12 of both wings are fixed to the tip of this shaft 11, and the shaft 11 is guided so as not to swing eccentrically during rotation. A holder 13 is provided. The blade plate 12 is provided in contact with the heating plate 14, which serves as the bottom plate of the main body 1, so as to be able to rotate and slide, and metaldehyde 4 is placed on the lower end surface of the blade plate 12 to prevent it from clumping. That is, a large number of escape holes 16 are provided in order to spread the powder thinly without being biased toward one side (rotation direction) of the rotating vane plate 12 in a powdered state. A heating device 17 such as an electric heater is provided below the heating plate 14 to heat the heating plate 14, and further heat the metaldehyde 4 being stirred by the blade plate 12.

In FIGS. 2 and 3, the supply device 5 for metaldehyde 4 has a rectangular cylindrical shape and is provided with a lid 18. At the bottom, there is a supply motor 19 that rotates at a very low speed, and a shaft 20 of this supply motor 19. A large number of radial flat plate-shaped supply vanes 21 are fixed, and the metaldehyde 4 is dividedly supplied into the sublimation chamber 8 between the supply vanes 21 .

In the above configuration, the main body is installed in a closed room equipped with an air conditioner in order to conduct an experiment to visualize the air flow distribution of air conditioners, that is, metaldehyde.
I put it. Then, metaldehyde 4, which is a powder material, is supplied to the supply device #6 in advance, and the heating device 17, such as an electric heater, is energized to heat the heating plate 4, and the stirring motor 6, blower 10, etc. are heated. The supply motor 19 is energized and operated. By this operation, the supply motor 19 is rotated at a very low speed, and as a result of this rotation, the metaldehyde 4 contained between the supply vanes 21 is supplied so as to slowly fall toward the corner of the sublimation chamber 8. The supplied metaldehyde 4 is almost on average directed toward the heating plate 14 at the bottom by the air that flows in from the air suction port 23 and is blown out from the indoor air outlet 9 in the direction of arrow A when the blower 10 is operated. drop down. That is, since the metaldehyde 4 has a certain amount of weight, it decreases downward while being scattered by the air flow within the sublimation chamber 8. The fallen metaldehyde 4 is stirred on the heating plate 14 by the rotating blade plate 12, and during this stirring, the metaldehyde 4 is sublimated by the heat of the heating plate 14. This sublimated metaldehyde 4 becomes a gas, and this gas is turned into powder in the sublimation chamber 8 and blown into the room from the indoor air outlet 9, and the metaldehyde 4 becomes visible and the powder of metaldehyde 4 floats in the room. While shining light on the cotton, the airflow distribution in the room is checked using the air blown out from the air conditioner.

In addition, the room referred to as the above-mentioned room is made in a closed room,
The above-mentioned main body 1 and an air conditioner are installed in this room, and together with S, the room filled with powdered cotton is illuminated, and the outside of the room is darkened.
The airflow distribution is visualized and confirmed while the sublimated cotton powder floating in the room is distributed by the air blown out from the outlet of the room air conditioner.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention includes a metaldehyde supply device in which a metaldehyde sublimation device made to visualize airflow distribution is provided on one side of the main body, and a metaldehyde It is equipped with blade plates connected to a stirring motor C to facilitate sublimation while stirring, and a blower that sends the sublimated metaldehyde powder into the room using a heating device that heats the metaldehyde. Since the metaldehyde is heated evenly while being stirred by a vane plate and then sent into the room, it is possible to obtain good powdering, and it is automatically sublimated, and after sublimation, it is powdered, which is different from conventional methods. It has the advantage that it can be carried out without relying on human manual labor while wearing a gas mask, and has no adverse health effects on the human body.
