Abstract

PURPOSE:To remove dust in a filter without detaching a pipeline by forming the title filter with a casing having end connections in three directions and a rotor holding a filter and connecting two end connections in the casing. CONSTITUTION:The casing 4 having end connections (a)-(c) in three directions from the center and two end connections (b) and (c) having the central angles beta1 and beta2 equal to that of the end connection (a) as a reference is provided. The rotor 5 having a passage capable of connecting the one end connection as a reference and another end connection and capable of being turned to an angle between at least the two end connections of the casing 4 with the center O as a reference is provided in the casing 4, and a filter 1 for closing the passage in the rotor 5 in the facial direction is set. As a result, the dust in the filter can be removed without detaching the pipeline.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a filtration device for removing dirt and the like that flows together with water in a water circuit of a forced circulation bathtub, water heater, or the like.

2. Description of the Related Art Conventionally, this type of filtration device has a structure in which a furnace-compatible filter 1 is installed in the middle of the piping between a fixed tube 2 and a fixed tube 3, as shown in FIG. It was designed to collect them and prevent them from entering downstream.

Problem to be Solved by the Invention However, in the above configuration, in order to remove the dust caught by the filter 1, the fixed cylinder 2 must be replaced by the fixed cylinder 3.
Since it is necessary to take out the filter 1, there is a problem in that it is necessary to provide room for moving the fixed cylinder 2 and the fixed cylinder 3 when assembling the piping in advance. Further, there are problems in that it takes time to remove the filter 1, and that the filter 1 may be forgotten to be attached during assembly or the like, or it may fall.

The present invention solves the conventional problems as described above.
The purpose is to eliminate work such as removing piping.

Means for Solving the Problems In order to solve the above problems, the overflow device of the present invention is composed of a casing having connection ports in three directions, a rotor having a filter inside the casing, and connecting the two connection ports of the casing. It is something that

Operation In the above configuration, the three connection ports of the casing are defined as an inlet, an outlet A and an outlet B, respectively. The rotor usually connects the inlet and the outlet A, and uses a filter inside the rotor to catch dirt and the like in the flow from the inlet to the outlet A. Next, as the rotor rotates, the inlet and outlet B are connected, and at this time, the flow flows from the inlet to outlet B, but since the direction of the flow inside the rotor is the opposite of normal, the dust inside the rotor is transferred to the outlet B. This will lead to more leakage.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In Fig. 1, 1 is a filter, 4 is a casing, and 5 is a filter.
is a rotor that has a filter 1 inside and is placed inside a casing 4. Here, a is the inlet of the casing 4 which is the inlet of the flow, b is the outlet, and C is the outlet of the flow containing dust caught by the filter l, and the angle β1 between the inlet a and the outlet is: It is equal to the angle β2 formed by the inflow port a and the discharge port C.

When the flow is normal, that is, from the inlet a to the outlet A, the rotor 5 has a flow path that connects them, and by having the filter 1 in this flow path, the dust is filtered out. It is stored on the inlet a side of No. 1. Next, the rotor 5 is rotated at the center O of the angle β1β2, and the flow path of the rotor, which was normally on the inlet a side of the casing 4, is now on the outlet C side, so that the flow path of the rotor 5 is The inflow port a and the discharge port C are connected, and the garbage caught by the filter 1 is transferred to the discharge port C by the flow.
more excreted. Next, by rotating the rotor 5 again to the normal state, the filter 1 can be reused in a dust-free state.

According to this configuration, the filter 1 can be cleaned without moving pipes or the like, and if the discharge port is connected to a sewer or the like, it is possible to easily dispose of garbage and the like.

Effects of the Invention According to the filtration device of the present invention as described above, dust can be removed from the filter without removing the piping. Furthermore, since no tools or skills are required to move the piping, and the work time required for this purpose is shortened, there is no longer a need for piping technicians who were previously required.
