The present invention relates to a ceramic filter assembly and a method for assembling the same, having an elastic member provided on the inner fastening member to simplify and assemble the assembly.

As the industry develops, the harmful substances such as dust, soot, waste gas, smoke, and volatile organic compounds (VOC's) generated in each industrial process are increasing. Therefore, in order to prevent the emission of such pollutants, some polymer filters are used, but polymer filters have weak problems in heat resistance, chemical resistance, abrasion resistance, and flame resistance.

In other words, polyester shrinks at 150 ° C, and PTFE (Teflon), which has excellent heat resistance, has only heat resistance of up to 250 ° C. The atmosphere of the process using an industrial filter is dust, various waste gases, and moisture. At the same time, it is a harsh environment, and most polymer nonwoven filters such as polyester, polypropylene, acrylic, polyamide, polyimide, and glass fiber can be used to jet dust or dust off the filter surface. When the dust falls, the surface wear of the filter by the dust is severe, which not only destroys the filter and shortens the cycle of use of the filter, but also causes sparks during the combustion process of each industry. , Filter, trash incinerator, boiler, coal-fired power plant, coal gasification complex In the case of power generation, there is a problem that the exhaust gas is exposed to the air, so it is opposed to the tightening environmental regulations.

 Therefore, in order to solve this problem, the development of ceramic filter has been made. Ceramic filter has much better heat resistance, chemical resistance, and abrasion resistance than polymer filter. There is no need to reduce installation and maintenance costs.

Hereinafter, a process of assembling the ceramic filter assembly 100 will be described with reference to FIGS. 4 to 11.

11 is a flowchart illustrating a method of assembling a ceramic filter assembly according to the present invention.

First, in order to assemble the ceramic filter assembly 100, a preparation step (S100) of preparing the upper cap 120, the ceramic filter 110, the lower cap 180, and the venturi 130 is performed as shown in FIG. 4. .

In this case, the number of the ceramic filters 110 may vary according to the size and use of the ceramic filter assembly 100. Accordingly, the number of the inner fastening members 150 and the outer fastening members 190 may also be changed. .

In addition, the upper buffer member 160 and the lower buffer member 170 may also be increased or decreased by the same number.

After the preparation step (S100), the cap coupling step (S200) is carried out. The cap coupling step (S200) is a step in which the upper cap 120 and the lower cap 180 are restrained from each other by the inner fastening member 150.

Looking at the cap coupling step (S200) in more detail, as shown in Figure 4 is coupled to the ceramic filter 110 in the upper portion of the lower cap 180 in a separate configuration. At this time, the lower buffer member 170 is interposed between the lower cap 180 and the ceramic filter 110.

The inner fastening body 152 may be screwed to the cap coupling part 184 before stacking the lower cap 180 and the ceramic filter 110.

The upper buffer member 160 is positioned above the ceramic filter 110, and the upper cap 120 is placed on the upper buffer member 160.

In this case, an upper portion of the ceramic filter 110 is accommodated in the upper matching portion 124, and an upper end portion of the ceramic filter 110 is seated on the interference surface 126. An upper buffer member 160 is interposed between the ceramic filter 110 and the upper cap 120.

When assembled as described above, the inner male screw 154 formed on the upper side of the inner fastening body 152 is exposed to the upper cap 120 through the through hole 122, and the elastic member 156 and the restraining member. By inserting 158 sequentially and screwed together, the elastic member 156 generates an elastic restoring force.

Since the elastic restoring force generated by the elastic member 156 presses the upper cap 120 downward, the upper cap 120, the ceramic filter 110, and the lower cap 180 are moved by the inner fastening member 150. This is limited.

Thereafter, the venturi fixing step S300 of fixing the venturi 130 using the outer fastening member 190 is performed.

That is, when the outer fastening body 192 is inserted into the seating portion 186 and pushed upward in the lower portion of the lower cap 180, the upper end of the outer fastening body 192 is connected to the lower buffer member 170. It penetrates through the ceramic filter 110, the upper buffer member 160, and the upper cap 120, and is screwed into the venturi coupling portion 133 recessed upward from the bottom surface of the venturi 130.

At this time, since the expansion part 196 provided at the lower end of the outer fastening member 190 is configured to have a larger cross-sectional area than the outer fastening body 192, it cannot be penetrated through the seating part 186, thereby limiting the upward movement range. The restraint force is generated on the venturi 130.

According to the above process, the assembly of the ceramic filter assembly 100 is completed.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention may be made by those skilled in the art within the above technical scope.

For example, in the embodiment of the present invention, the inner fastening member 150 has only the elastic member 156 and the restraining limiting member 158, but the elastic member 156 is provided with a washer (reference numeral 159 in FIG. 4) Of course, the elastic member 156 may be configured to more stably exhibit the elastic restoring force.
