Abstract

PURPOSE:To form exhausting and heating devices, each of which produces uniform temperature distribution and consequently no diffusion of mist and gives no influence to working space, by a method wherein a plurality of blow-off ports are provided on a floor surface, radiant heating means are provided on the ceiling in the positional relationship so as to oppose to the air supply means and the supply air from the air supply means is exhausted from the roof. CONSTITUTION:Blow-off ports 16 are arranged on the floor 1 surface at the predetermined intervals, which are determined under the consideration that no mist stagnates at the central portion of a factory F. In addition, the provision of blast ducts 17, which have blow-off ports directed toward the interior of the factory, at a plurality of positions near the outer side walls 6 may produce good result. Further, radiant heaters 18 hang down by hanging braces 19 utilizing the beam. The heaters 18 may be hung down below the underside of the beam 3. In this case, it is necessary for the heaters 18 not to hinder the installation of cranes and the like. Furthermore, as for exhausting means, exhaust fans 20 are provided on one side wall of a monitor roof and windows 21 are provided on the other side wall.

Description

[Detailed Description of the Invention] A2 Field of Application of the Invention The invention is based on the dust (hereinafter referred to as mist) generated in large quantities in cutting factories.
)'fx Which exclusion and at the same time equipment for heating in such factories (= relates to).

BACKGROUND OF THE INVENTION Conventional ventilation mechanisms in factories have been to install roof fans on the roof surface at predetermined intervals C2, and to perform ventilation while sucking air from the bottom of the outer wall of the factory. Therefore, the ventilation airflow immediately rises from the bottom of the side walls toward the ceiling and is exhausted as is, so there is almost no inflow into the center of the factory. Therefore, the reality is that the mist generated during the cutting process and staying in the center of the factory is extremely difficult to remove.

Therefore, we provided air outlets that blow upward at a plurality of locations on the floor surface at predetermined intervals, and provided exhaust means on the roof surface to provide exhaust means that can easily remove mist from the center of the factory.

However, heating equipment in factories has traditionally been hot air heaters, so when the amount of ventilation from the exhaust outlet increases, the heating load also increases, and if the ceiling of the factory is high, the temperature difference between the top and bottom will increase. The mist is easily diffused by the hot air for heating and the air for ventilation, and the hot air heater! Distributed installation resulted in a decrease in space efficiency.

C.6 Objective of the Invention Therefore, an object of the present invention is to provide an exhaust and heating device that is less affected by the amount of ventilation, has a uniform temperature distribution, does not diffuse mist, and does not affect the working space.

29. Structure of the Present Invention The feature of the present invention is that a plurality of blowers are arranged at predetermined locations including the central part of the floor surface to create an upward air flow! The heating means is equipped with a radiant heating means installed on the ceiling in a position opposite to the air supply means, and a place where the air from the air supply means is exhausted from the roof. be.

Therefore, the present invention not only makes it possible to efficiently eliminate the mist Z generated and accumulated in the center of the factory through the outlet on the floor, but also reduces the amount of ventilation by heating the factory with radiant heating means. Heating can be done effectively with little impact.

E, Example Next, the present invention will be explained in detail with reference to the drawings.

In Fig. 1, the structure of factory F consists of a plurality of steel columns 2. ... stands in a predetermined position and supports a beam 3 assembled by a place, the upper surface of this beam is made up of a roof 4 by laying corrugated iron plates, and the center part of this roof is constructed as an overhanging roof 5. However, the outer periphery is provided with an outer wall 6.

To explain the air supply means, a horizontal duct 7 connected to a blower is installed between the Breines, and a descending duct 8 from the ceiling that communicates with this duct is a second
As shown, steel column 2. It is constructed using selected materials from... That is, the outer periphery of the steel column 2 is surrounded by a steel plate 9 to form a ventilation passage 10g inside, and the lower end is located at the bottom of a groove 11 formed by drilling one floor. A part of the groove is cut out to form a discharge port 12, and a heavy gray ring 13 is attached to the upper opening edge of this groove.
are mated. As is well known, the steel column 2 is supported by a foundation footing 15 formed at the upper end of the foundation pile 14.
are arranged at a predetermined interval on one floor as shown in the third diagram,
This interval must be designed to prevent mist from accumulating in the center of the factory F. Further, a plurality of ventilation ducts 17 having air outlets Z may be provided at a plurality of locations close to the outer wall 6 so as to be able to go around inside the factory.

Next, the radiant heater 18 is suspended by a hanging support 19 using a beam as shown in the second figure.

Of course, the heater 18 may be suspended below the lower surface of the beam 3, but in this case it is necessary to ensure that it does not interfere with the installation of a crane or the like.

Further, the exhaust means includes an exhaust fan 20 provided on one side wall of the overhanging roof 5 and a window 21 provided on the other side wall as shown in the second figure.

In addition, if the exhaust fan 20 faces south and the window 21 faces north, direct sunlight can be blocked in the summer, which is effective in suppressing indoor temperature rise, and the window 21 is also effective as a natural lighting and natural ventilation opening. be.

Furthermore, the rotation speed of the exhaust fan 20 is changed by an inverter to provide ventilation suitable for the situation.

According to the present invention, which has a configuration that exceeds the effects of the present invention, mist in the center of a factory or the like can be efficiently removed by the air supply from the outlet and the exhaust means without being diffused by the heating means. Since the heating means is a radiation method, heating is possible without being affected by the amount of ventilation, the temperature distribution is uniform, and since it is a ceiling fan, it has no effect on the physical space.
