Description

[Detailed description of the invention] The present invention relates to a filter device suitable for removing dust, etc. from the air, and in particular, a filter element suitable for collecting dust, bacteria, etc. in a glow box, for example, is installed in a mounting cylinder. The present invention relates to a filter device.

In recent years, there have been many opportunities to use grow boxes in various industries.

Although a filter element from which dust and bacteria have been removed from the grow box is used, the inside of the grow box is usually contaminated, and there is a risk that dust and the like will be scattered when the filter element is replaced.

Therefore, conventionally, there is a problem in that it is difficult to replace the filter element (remove the old element and install the new element).

The purpose of the present invention is to provide a filter device that eliminates the inconveniences of conventional devices, and the present invention is to attach a mounting cylinder formed from a hollow cylinder or the like by penetrating the wall surface of the grow box. , a lid is provided at the outer end of the mounting cylinder that is opened only when the filter element is inserted into the mounting cylinder, and the mounting cylinder also has an intake (or exhaust) lid that communicates with the inside of the grow box via the filter element. ) By providing a pipe and a measurement port to measure the pressure between the upstream and downstream points of the filter element, the pressure loss of the filter element can be measured, and when the filter element becomes clogged, the installation The filter element can be replaced by opening the lid at the outer end of the cylinder, inserting a new filter element into the mounting cylinder, and pushing the old filter element out of the mounting cylinder and into the grow box through the new filter element. It is characterized by the fact that it performs the following functions.

Next, embodiments of the present invention will be described with reference to figures.

In Fig. 1, 1 is a mounting cylinder hollowed out from a hollow cylinder;
The mounting cylinder 1 is attached to the wall surface 4 of the glow box 3 by penetrating the wall surface 4 by means of a flange 2 provided on its outer periphery.

5 is a filter element inserted into the mounting cylinder 1 from above (the filter element will be described later with reference to FIG. 2), and 6 is a lid provided at the upper end of the mounting cylinder 1, which prevents the filter element 5 from being inserted. Closed except during business hours.

A pin 7 is fitted into the lid 6, and the filter element 5 inserted into the mounting cylinder 1 is pushed down by the pin 7 and held at the illustrated position.

8 is an intake (exhaust) pipe that opens at a position above the set position of the filter element 5; 9 is the filter element 5;
Pressure loss measurement ports are provided at the upstream and downstream portions of the filter element 5, respectively, and a pressure gauge 10 (see FIG. 3) is linked thereto.

In FIG. 2, the filter element 5 includes, for example, a body 12 formed into a hollow cylindrical body by bending nonflammable glass fiber paper 11 treated with waterproof, antibacterial, and antibacterial treatments at regular intervals; The cylindrical part 14 is made of a porous metal plate provided on the outer periphery, and the rubber annular gasket 15 and leg piece 16 are provided on the outer periphery of the cylindrical part 14. The outer diameter of the gasket 15 and leg piece 16 is , is slightly larger than the inner diameter of the mounting cylinder 1, and when the filter element 5 is inserted into the mounting cylinder 1, the filter element 5 is held by the elastic force of the gasket 15 and the leg piece 16 against the inner wall surface of the mounting cylinder 1. It looks like this.

As shown in FIGS. 3A and 3B, this filter device is installed through the wall surface 4 of the glow box 3, and is attached to the intake pipe 8.
Introduce outside air into the grow box 3 through (Fig. 3A)
The gas in the glow box 3 is discharged via the intake filter device that filters the incoming air and the exhaust pipe 8 (the third
Figure B) L shows the filtration of the exhaust gas.It is used as a pair with an exhaust filter device attached to a glow box.

Note that the arrows in FIGS. 3A and 3B indicate flowing water of gas (air).

In such use, the clogging state of the filter element 5 is detected by the pressure gauge 10.

Then, when a predetermined degree of clogging occurs, the filter element is replaced.

The exchange is performed in the following manner.

First, remove pin 7 and lid 6. Next, a new filter element 5 is inserted into the mounting cylinder 1 from the upper end of the mounting cylinder 1 with the gasket 15 side facing toward you.

Furthermore, the new filter element 5 is pushed down with a separately prepared discharge rod, and the old filter element below it is discharged from the mounting cylinder 1.

The filter element designated by reference numeral 5'' in FIG. 1 is an old (clogged) filter element discharged from the mounting cylinder 1.

In the example shown in Figure 1, there are usually two filter elements.
5.5' are installed in the mounting cylinder 1, and replacement is performed by ejecting the one at the lowest position and moving it sequentially downward.

The filter element 5'' discharged from the mounting cylinder 1 falls into the glow box 3 and remains there.

When the placement of the new filter element 5 is completed, the ejection rod is removed, the lid 6 and the pin 7 are returned to their original positions,
The filter element replacement work is completed.

As described above, in this invention, when replacing the filter element, the old filter element is not taken out of the device, so there is no risk that dust or bacteria attached to the old filter will scatter and contaminate the atmosphere. It will be completely eliminated.

In this way, in this invention, the filter element insertion port is located outside the grow box, and a clogged filter element can be replaced by operating from the outside, which simplifies the work required to replace the filter element. In addition, since the old filter element is not taken out into the outside air, there is no risk of contaminating the area around the filter device, and the replacement work of the filter element can be made extremely simple and easy. The effect is significant.
