Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ceramic filter fixing device applied to an exhaust gas treatment or dust removal device.

[0002]

A filter guide 5 having a cylindrical edge is attached to the lower surface of the upper plate 4 coaxially with the hole 6.

Below the upper plate 4, a dish-shaped tray 1, a lower packing 2 b, a cylindrical ceramic filter 3, and an upper packing 2 a are arranged coaxially in the hole 6 from the bottom. Then, the connecting rod 10 is coaxially passed through the hole 6 and connected between the receiving tray 1 and the spring receiving plate 9.

[0005]

[Problems to be solved by the device]

When a ceramic filter is used for an exhaust gas treatment or dust collecting apparatus, about 1500 to 2000 filters are required in an apparatus of 30,000 Nm ³ / h scale.

At this time, the above conventional technique has the following problems.

Since each ceramic filter is fixed individually, the number of springs is large and the fixing work becomes complicated.

[0008] Replacing the filter also involves complicated work.

Since the spring receiving plate is required to utilize the spring force, the upper part of the filter is blocked and it becomes difficult to install the backwash nozzle.

[0010]

[Means for Solving the Problems]

 The present invention takes the following measures to solve the above problems.

(1) A rectangular frame type pedestal; a plurality of dish-shaped lower guides arranged on the pedestal at predetermined intervals; arranged above the pedestal and opposed to the lower guide. An upper plate having a hole having a predetermined diameter at a position; a cylindrical upper guide coaxially attached to the hole on the lower surface of the upper plate; a lower packing and a cylindrical solid body sequentially arranged between the lower guide and the upper guide A porous filter and an upper packing; connecting means for connecting the four corners of the pedestal and the upper plate and having a lifting spring at the upper part; And a backwash nozzle.

(2) A rectangular frame type spring pedestal; a pedestal arranged above the spring pedestal and having substantially the same shape as the spring pedestal; a plurality of pedestals arranged on the pedestal at a predetermined interval A dish-shaped lower guide; an upper plate disposed above the pedestal and having a hole of a predetermined diameter at a position facing the lower guide; a cylindrical upper guide mounted on the lower surface of the upper plate coaxially with the hole And a lower packing, a cylindrical solid porous filter, and an upper packing, which are sequentially arranged between the lower guide and the upper guide; and a spring, which is disposed below the lower guide between the spring pedestal and the pedestal; A connecting rod for connecting between the four corners of the spring support and the upper plate is provided.

[0013]

[Action]

 (1) In the above invention 1, when the pedestal and the upper plate are connected by the connecting means, the pedestal and the upper plate are clamped by the spring, and each cylindrical solid porous filter has a lower packing and an upper packing. Fixed through.

Therefore, unlike the conventional example, each filter is not fixed, but a plurality of filters are fixed by four connecting means, so that the number of steps can be significantly reduced.

(2) In the above invention 2, when the spring pedestal and the upper plate are connected by the connecting rod, the pedestal and the upper plate are clamped by the spring, and each cylindrical solid porous filter has a lower packing. It is fixed via the upper packing.

Therefore, unlike the conventional example, each filter is not fixed for each filter, but a plurality of filters are fixed by four connecting means, so that the number of steps can be significantly reduced.

【Example】

 (1) An embodiment of the present invention 1 will be described with reference to FIGS.

In FIG. 1, a quadrangular frame type pedestal 11 is provided. As shown in FIG. 2, dish-shaped lower guides 5b are mounted on the pedestal 11 at predetermined intervals in 3 rows and 3 columns.

A hole a having a predetermined diameter is formed in the upper plate 4 arranged above the receiving table 11 at a position facing the lower guide 5b of the receiving table 11. A cylindrical upper guide 5a is coaxially attached to the hole a on the lower surface.

The lower packing 2b, the ceramic filter 3, and the upper packing are sequentially arranged between the lower guide 5b and the upper guide 5a. A connecting rod 17 is inserted between the four corners of the pedestal 11 and the upper plate, and is fixed by a nut 20 via a spring 18 placed on the upper plate 4. That is, the pedestal 11 is lifted up via the spring 18 and the ceramic filter 3 is fixed.

A backwash nozzle 19 is provided downward above the center of the hole a of the upper plate 4.

As described above, the nine ceramic filters 3 are fixed by the four connecting rods 17, so that the assembly man-hours, the filter replacement work man- The number of springs will decrease. In addition, the gas flow is improved because there is no connecting rod that passes through the filter. Further, since the backwash nozzle 19 can be arranged right above the hole a, the backwash effect is enhanced.

(2) An embodiment of the present invention 2 will be described with reference to FIGS.

In FIG. 3, as shown in FIGS. 4 and 5, a rectangular frame-shaped spring support 23 and a support 11a having substantially the same shape are provided. The pedestal 11a is provided above the spring pedestal 23.

On the upper surface of the spring receiving table 23, the receiving trays 21b are attached at predetermined intervals in 3 rows and 3 columns. A tray 21a is attached to the lower surface of the receiving base 11a facing the spring receiving base 23. Further, a lower guide 5b is attached at a position opposite to the tray 21a. The upper plate 4 has substantially the same structure as that of the above embodiment.

A spring 24 is arranged between the pan 21b of the spring pedestal 23 and the pan 21a of the pedestal 11a. Further, the ceramic filter 3 and the like are arranged above the pedestal 11a as in the above embodiment. Further, the connecting rods 17 a are passed between the four corners of the spring receiving base 23 and the upper plate 4 and fixed by the nut 20. As a result, the pedestal 11a is pushed up by the spring 24 and the ceramic filter 3 is fixed.

The operation and effect are almost the same as those in the above-mentioned embodiment.

[0028]

[Effect of device]

 As described above, according to the present invention, since the plurality of filters are fixed at once by the connecting means at the four corners, the number of assembling steps and the number of replacing steps are greatly reduced.
