Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a filth crushing and discharging device for a flush toilet, which is used in connection with a flush toilet.

Conventionally, this type of filth crushing and discharging device has been used to remove sewage discharged from flush toilets, hard plastics mixed in with filth,
Impeller rotation is obstructed by foreign objects such as metal pieces,
The impeller is damaged, the crushing efficiency is reduced, and in the worst case, it breaks down and becomes unusable.

The present invention provides an intermediate chamber between the drain pipe of the flush toilet and the inflow chamber in the casing, and also provides a weir inside the chamber.
To provide a filth crushing and discharging device which protects an impeller by blocking foreign matter having a specific gravity heavier than solid filth by a weir to prevent it from flowing in, and at the same time improves the crushing efficiency of the impeller.

An example of implementing the present invention will be described below based on the drawings.

In the figure, 1 is a casing, 3 and 4 are an inflow chamber and a water level detection chamber formed inside, respectively, and there is an intermediate space between this inflow chamber 3 and a drain pipe 6 directly connected to a flush toilet (not shown). A room 7 is provided.

The inflow chamber 3 and the water level detection chamber 4 are constructed by controlling the inside of the casing 1 by means of the casing 1 wall, first and second screens 2, 2' having a large number of small holes 9 provided in the functional section A, and the main body of the functional section A. They are divided and formed so that both are adjacent to each other.

Functional part A consists of a motor a, a pump casing 10, an impeller 5, and a crushing chamber 11, and a rotating shaft 1 of the motor a.
2 extends into the pump casing 10 connected to the lower end of the motor casing 13, and the impeller 5 is integrally attached and fixed within the pump casing 10.

The pump casing 10 has a hole at one end connected to the discharge pipe 14, and an opening 15 at the center of the lower end so as to communicate with the crushing chamber 11 provided at the lower end of the casing 1. Rotor 16 of impeller 5 to crushing chamber 11
With a protruding opening.

The impeller 5 includes a rotor 16 projecting from the projecting port 15 and having an inverted triangular shape, and a discharge pipe 1 located within the pump casing 10 and connected to the discharge port 17 using rotational force.
4, and a pump section 19 that can discharge crushed waste from the pump section 4.

A plurality of suction ports 2 are provided in the rotor 16 and the pump section 19.
0 are opened in communication with each other, and the outer edge of this rotor 16 serves as a rotary blade 21, which is brought into contact with a fixed blade 22 of a crushing chamber 11 provided at the lower part of the pump casing 10 so as to face the inflow chamber 3. .

This crushing chamber 11 is a mounting part for a fixed blade 22 that comes into contact with the rotor 16 and can crush dirt. It is located on the bottom surface of the casing 1 under the vertical axis of the rotating shaft 12, and has a partition wall 23 erected behind it so as to remain independent of the water level detection chamber 4.

The casing 1 configured in this way and a flush toilet bowl (not shown) are not directly connected through the drain pipe 6, but an intermediate chamber 7 is interposed between the two.

As shown in FIG. 2, this intermediate chamber 7 is a wide room that looks like an extension of the opening of the inflow chamber 3, and the connecting part of the lower wall soil of this intermediate chamber 7 with the drain pipe 6 is connected to the inflow chamber 3. A weir 8 is erected between the toilet bowl and the flush toilet bowl to block filth discharged from the flush toilet bowl and foreign matter with heavy specific gravity mixed into the sewage so that they do not reach the inflow chamber 3.

The weir 8 has a trapezoidal shape in the illustration, and may have any shape as long as it has a high damming rate, but it is desirable to have a shape and height that allows at least sewage and filth to pass through.

Further, in the water level detection chamber 4, a pair of electrode rods 24 are arranged side by side, which allow only cleaning water or waste water to pass through without contaminating dirt, and are energized by the rise and fall of the water level to regulate the rotation of the motor a. The first electrode rod 24 has a large number of small holes 9 to prevent dirt from adhering to the electrode rod 24. 2nd screen 2,
A partition is formed at 2' to prevent dirt from entering.

In this filth crushing and discharging device, the drain pipe 6 from the flush toilet is attached to the intermediate chamber 7, and in the intermediate chamber 7, filth and foreign matter mixed in the sewage (for example, hard plastics and metals) are removed. debris, etc.) and remove the residue, i.e., filth,
Sewage is caused to flow into the crushing chamber 11, and as the water level rises, the crushing chamber 1 is driven by the motor a via the electrode rod 24.
By rotating the rotor 16 in 1, a rotary blade 21 and a fixed blade 22 are created.
and a water discharge pipe 25 that finely crushes the crushed materials and flows the crushed materials into the pump casing 10 through the suction port 20, and connects the crushed materials to the discharge pipe 14 and the upper wall of the casing 1 by the centrifugal force of the pump section 19. to be forcibly ejected.

As mentioned above, the present invention has an intermediate chamber between the flush toilet and the inflow chamber, and a weir is installed in the intermediate chamber, so that foreign substances such as metal pieces and hard plastics that get mixed in with filth and sewage are removed. To provide a waste crushing and discharging device which is dammed up from the weir and does not reach the crushing chamber, and therefore does not damage a screen, an impeller, etc. to cause failure or sludge, and has excellent durability and crushing efficiency.

In addition, foreign matter is dammed up in the intermediate chamber before the inflow chamber, so
When removing foreign matter, it is easy to remove the connection with the inflow chamber, and there is no need to use other cleaning tools in each inflow chamber to remove foreign matter, which also simplifies the cleaning work during cleaning. .

Furthermore, since this intermediate chamber is simply interposed between the inflow chamber and the discharge wood pipe, it also has the advantage that it can be used as is in conventional devices of this type.

Therefore, the intended purpose can be achieved.
