DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding structure for fixing a filter plate to a bottom plate in a filtering section of a multifunctional filter.

[0002]

2. Description of the Related Art FIG. 6 is a diagram showing an example of the configuration of a conventional multifunctional filter. In the example shown in FIG.
A multi-function filter is provided by a filtration unit 54 including a bottom plate 52 and a filtration plate 53 forming the bottom of the can body 51, and a stirring blade unit 55 provided in the can body 51 for stirring slurry and the like in the can body 51. Was composed. As a holding structure for fixing the bottom plate 52 and the filtration plate 53 in the filtration unit 54 of the above-described multi-function filtration machine, as shown in FIG. And a holding structure in which a filter plate 53 is superimposed on a bottom plate 52 of a bottom-up structure and fixed on the upper surface and side surfaces by a holding member 57 as shown in FIG.

[0003]

However, in the above-described conventional holding structure, a separate member for holding is required in any case, so that the structure of the filtering section becomes large, and as a result, the multi-functionality is increased. There was a problem that the structure of the whole filter became large. Further, in the example shown in FIG. 7, there is a problem that only the rubber member 56 made of a rubber material or a spring material is used. Further, in the example shown in FIG. 8, since a pressing member or the like is present on the filtering unit, there is a problem that a liquid to be treated is accumulated on the upper surface of the filtering unit, and the pressing member 57 is made of metal or Teflon. However, in the case of metal, there is a problem in corrosion resistance, and in the case of Teflon, there is also a problem that wear resistance is deteriorated. Furthermore, not only the holding portion having the above-described configuration, there is also a problem that in the conventional multifunctional filter, the actual temperature of the filtering portion cannot be measured only by measuring the temperature of the filtering portion from the side of the can body. there were.

An object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a structure for holding a filtering section of a multifunctional filter having a filtering section which can be fixed with a simple and small configuration and has a reliable sealing property.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a multi-function filter comprising a filter for holding a filter, comprising: a can body; a filter section comprising a bottom plate and a filter plate provided at the bottom of the can body; A holding structure for fixing the filter plate to the bottom plate in the filtration section of the multifunctional filter comprising the stirring blade section, via a taper hole provided in the bottom plate and a pin hole provided in the filter plate, A pin with a flat head and a core embedded in the lower part is inserted and screwed via a taper spacer with the core of the pin inserted into a tapered hole with the head of the pin holding down the filter plate. The bottom plate and the pin are sealed by a wedge effect, and a filter plate is fixed to the bottom plate, and a temperature sensor is embedded in the pin, and / or a heat source is embedded in the pin. It is characterized by the following.

[0006]

In the construction described above, the bottom plate and the filtration plate constituting the filtration section are fixed by a plurality of pins embedded with a metal core having a predetermined shape, so that a conventional ring member or holding member is not used. The bottom plate and the filter plate can be fixed, and a holding structure can be achieved with a simple and small configuration while maintaining high sealing performance. Further, since it is not necessary to use the pressing member, the liquid pool on the upper surface of the filtration unit can be reduced. Further, when a temperature sensor is provided inside the pin, the temperature of the filtration unit can be directly measured, and when a heat source such as a heater is provided inside the pin, it can serve as a heater. It is preferable that the material of the pin is a glass lining body or a ceramic body because it has corrosion resistance.
