[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a felt mat filter extraction jig used for cleaning or replacement of clogging as a filter in maintenance of a cylindrical felt mat filter used in a chemical plant.

[0002]

[Prior art]

 FIG. 2 is a conceptual view of the installation of the felt mat filter in the chemical plant, and FIG. 4 is a conceptual view of the felt mat filter taken out according to the conventional technique. The conventional technique will be described with reference to FIGS. 2 and 4 below. Will be explained.

When the cylindrical felt mat filter installed in the chemical plant device is replaced for clogging cleaning or replacement, the felt mat filter outer shell 2 and the felt mat filter 3 in the chemical plant are sealed and fixed. Since the pressure contact force of the O-ring 4 is strong, attach the wire 6 with the stand to the prefabricated peripheral groove 5 of the plastic case attached during the felt mat filter manufacturing process at the end of the felt mat filter, and attach the chain block etc. I was using it.

[0004]

[Problems to be solved by the device]

 In such a conventional method, preparatory work such as temporary installation of a tool for giving a pulling force to a chain block or the like, or a plastic case attached in the process of manufacturing a felt mat filter at the end portion of the felt mat filter 3 of the wire with base 6 are used. It took time to attach it to the ready-made circumferential groove 5. Also, the occupation range tends to be widened due to the arrangement of chain blocks, etc., so it is difficult to say that it is efficient.

In addition, when the base wire 6 is attached to the ready-made peripheral groove 5 of the plastic case at the end of the felt mat filter, a partially biased force is applied when the wire is pulled out by using a chain block, etc. There was a risk of breakage.

[0006]

[Means for Solving the Problems]

 FIG. 1 is a block diagram of a felt mat filter extracting jig according to the present invention, and FIG. 3 is a schematic view of an embodiment of using the felt mat filter extracting jig according to the present invention. However, a felt mat filter extraction jig based on the present invention will be described.

The present invention installs a pair of assembly halved rings 11 in a prefabricated circumferential groove 5 of a plastic case at the end of a felt mat filter, pulls the halved assembled ring by applying the method of gear puller, and felt mat filter 3 Pull out.

[0008]

[Action]

 The pull-out nut 18 is tightened to pull out the pull-out bolt 16, the connecting bolt 13 is pulled through the connecting bar 14 and the connecting nut 15, and the felt mat filter 3 is pulled out through the pair of assembly halves 11.

[0009]

【Example】

 An embodiment of a felt mat filter extraction jig according to the present invention will be described below. An end of the felt mat filter 3 attached to the felt mat filter mounting outer shell 2 in the chemical plant with a pair of assembled split rings 11 each having a connecting bolt 13 on the top of the outer peripheral ring surface and bending the end in a brim shape. Part of the plastic case is assembled and fixed to the ready-made peripheral groove 5 by using two sets of assembling bolts and nuts 12.

Then, a connecting bar 14 having a pull-out bolt 16 having a bolt hole penetrating the two connecting bolts 13 and screwed in the center and fixed with a locking nut 20 is connected to the two connecting bars 14. It is connected to the two connecting bolts 13 via a nut 15.

Further, the pull-out bolt 16 is passed through a bolt hole of the fixed bar 17 which penetrates the pull-out bolt 16 and is temporarily attached to the fixed bar 17 via a pull-out nut 18.

After that, the felt mat filter mounting outer shell 2 in the chemical plant is mounted and fixed to a bolt hole (not shown) of the flange surface 7 of the outer shell 2 for mounting the felt mat filter through two fixing bar set bolts 19.

Here, when the extraction nut 18 is tightened, the extraction bolt 16 is drawn, and the two connecting bolts 13 are drawn through the connecting bar 14, so that the felt mat filter mounting shell 2 in the chemical plant is inserted. The felt mat filter 3 is attached to the prefabricated circumferential groove 5 of the end plastic case of the attached felt mat filter 3 by using the assembling bisected ring 11 which is assembled and fixed using the two sets of assembling bolt nuts 12. Then, it is extracted from the felt mat filter mounting shell 2 in the chemical plant.

At this time, if the O-ring 4 sealing and fixing the felt mat filter 3 to the felt mat filter mounting outer shell 2 in the chemical plant comes off from the sealing surface on the felt mat filter mounting outer shell 2 side in the chemical plant. Since the felt mat filter 3 can be easily pulled out, the two fixing bar set bolts 19 which were fixedly attached to the bolt holes (not shown) of the flange surface 7 of the felt mat filter outer shell 2 in the chemical plant are installed. The felt mat filter 3 may be removed and the felt mat filter 3 according to the present invention may be taken out together with the jig.

[0015]

[Effect of device]

 By implementing the felt mat filter extraction jig based on the present invention, handling of the felt mat filter is extremely simple, skill is not required, occupation area is extremely small, workability and work efficiency are extremely good, and the felt mat filter can be extracted. It has become possible.
