Description

[Detailed Description of the Invention] The present invention relates to a wastewater trapping device for separating and collecting foreign substances mixed in wastewater.

Normally, if wastewater mixed with foreign substances is discharged into the sewer, etc., it will damage the sewer pipes, etc., so a blocking device is installed at the point where the wastewater is dumped, and the wastewater is forced to pass through the device and is discharged to the sewer. However, conventional such devices are
As shown in the figure and FIG.
A plurality of compartments 3'a, 3'b, which communicate with each other at 'b'
3'C... is designed to efficiently separate and store foreign substances within the casing 1', that is, to improve the blocking efficiency.

By the way, the partition plates 2'a and 2'b have guide grooves 5'a, 5'b and 5'C formed in the side wall plates 4'a and 4'b of the casing 1', as seen in the drawing. When cleaning the inside of the casing 1', the casing 1' is pulled up and removed, but foreign substances in the wastewater passing through the device are The foreign substances adhere to the inner surface of the body 1' and, of course, fill the guide grooves 5'a, 5'b, 5'C, and 5'd, making it difficult to pull them up.

Particularly in the case of kitchen wastewater, which is frequently used, animal fat is mixed in as a foreign substance, which causes further difficulty as it sticks to the wall panels and grooves.

The present invention aims to eliminate such drawbacks and provide a commercially available blocking device that is easy to clean and maintain.An example of the implementation of the present invention will be described below with reference to the drawings.

FIG. 3 is a perspective view of the entire device of the present invention, FIG. 4 is an enlarged perspective view of a portion thereof, and FIG. 5 is a front view of the intermediate plate.

In the drawing, 1 is a case, 2a and 2b are partition plates,
Inside the box, there are a plurality of compartments 3a, 3 that communicate with each other.
It is divided into b, 3C...

The above structure is the same as the conventional one, but the present invention uses L-shaped plates that are integrally fixed to the wall surface of the casing, instead of attaching the partition plates 2a and 2b using grooves. Let it be done.

That is, the L-shaped plates 5a and 5b, and 5C and 5d are provided in pairs at the same positions facing each other on the longitudinal side wall plates 4a and 4b of the case 1, and in this case, A locking pawl P is provided at the lower end of each L-shaped plate, and 5a and 5C and 5b and 5d are on the same wall surface, and each pawl faces each other to form a square surrounded by each pawl. It is fixed by shaping the corner of the frame.

Thus, when the partition plates 2a and 2b are inserted in a hanging state from above in a state perpendicular to the side wall plates 4a and 4b, they come into contact with the claw surfaces of the L-shaped plates 5a and 5b and 5C and 5d, respectively. , the lowering thereof is stopped, and an intermediate plate 6 is fitted between the partition plates 2a and 2b to prevent the partition plates 2a and 2b from falling down.

This includes guide plates 7a and 7b having a hook plate P' at the lower end of each partition wall plate 2a and 2b at a height direction position approximately in the vicinity of the center thereof.
In this opposed state, the Okima board 6 is suspended from above along the guide plates 7a, 7b and comes into contact with the claw surface P', thereby stopping its descent. There is.

At this time, both ends of the intermediate plate 6 are shaped like tapered surfaces that widen upward as shown in FIG. be.

Thus, the intermediate plate 6 may be lowered by only the weight of the intermediate plate itself, but it may also be pressed by applying a constant pressure from above.

In addition, 8a and 8b are stoppers for preventing the floating part after being pushed in.

In the above explanation, both ends of the intermediate plate 6 are formed into tapered surfaces so that the intermediate plate 6 is gradually expanded during descent, but the intermediate plate itself is made of a flexible material and has elastic Alternatively, other arbitrary means may be adopted.

The device of the present invention is constructed as described above, and in order to remove the bulkhead plates 2a and 2b during cleaning, each bulkhead plate 2 is removed by removing the stoppers 8a and 8b and pulling up the intermediate plate 6. Since a and 2 b lose their support, they can be easily taken out upwards.

In the present invention, since a groove means is not adopted for taking in and taking out the partition plates 2 a and 2 b, there is no possibility that the partition plates 2 a and 2 b cannot be pulled up due to adhesion of fat, etc., and the taking out operation is easy.

In addition, adhering fat can be easily removed, and cleaning and maintenance can be carried out extremely efficiently.

In the drawings, 9 is a strainer and 10 is a drain pipe.

Claims (1)

[Scope of utility model registration request] Four L-shaped plates each having a locking pawl at the lower end are mounted at regular intervals in the same position facing each other in the height direction of the longitudinal side wall plate forming the casing, and each The locking claws of the plates are arranged to form one corner of an enclosed rectangle inside, and the two partition plates that partition the side wall plates are arranged perpendicularly to each side wall plate. It is installed in a hanging state from above,
The lower end of each bulkhead plate is placed on the locking claw and stopped, and on the other hand, a guide plate having a locking claw at the lower end is located at a height direction position approximately in the center of each partition plate. are arranged in opposition to each other, and an intermediate plate is interposed between the two guide plates, the ends of which are tapered upward so that the two plates can be stretched apart. This is a wastewater blocking device.
