Description

[Detailed description of the invention] This invention is a separating element on the separation surface of a wet filter (strainer) for separating sewage, mud, peat, etc. in water, or for separating solid particles contained in water from water. Because this type of separation element captures and separates microscopic particles from the water at the edges, it is required to be very fine and extremely precise throughout, especially at the edges. The formation of a sharp separation surface that sharply catches fine particles from the flow and separates them from water is considered an essential condition for improving separation precision and efficiency.

For this purpose, the present invention seeks to achieve delicate acuity by forming the separating element body into a relatively thin and long metal plate strip, and this is constructed by punching out a metal plate such as a ribbon or band shape. This realizes integral punching of the guide and support pieces, which has a positive effect on cost while streamlining the accuracy improvement in the process of constructing the separated element body.

In the past, apart from the wet filtration machine of the present invention, a so-called vibrating sieve separating element made of cast steel has been known;
It is used for sieving rocks, etc.), and in order to withstand these large impacts and frictional resistance, the thickness (around 3Q mm) and width (around 100 mm) of the element body itself are extremely large. The slits) are also coarse.

Moreover, since it is a casting process, only short and thick pieces with a length of about 3QQ mm can be obtained, which is completely different from the long, delicate and sensitive separating element in the wet filtration machine of this invention, and it is impossible to expect a high-precision separating plate surface. This is a rough concept.

Conventionally, as shown in FIGS. 9 to 11, this type of separate element body has used a metal wire rod and curved it in the shape of glasses at appropriate places to form a small ring 2' for attachment. Since the cross-neck part C of ' is compressed during compression molding, this part is very weak and easily breaks, and since the small ring 2' is a flexible ring shape with ends, the whole wire rod 1' is This results in unnecessary latent force being retained, and the tightening of the nut 5' etc. on the connecting rod 3' causes distortion on the surface of the separation plate A', reducing accuracy and making it difficult to form stable and uniform slits and separation surfaces. It was making it difficult.

This becomes noticeable when the wire rod 1' is curved into an arc shape (rounded).

This invention is a device made to eliminate these obstacles on the separation surface, and to explain its embodiment, since the separation blade strip plate 1 is formed into a strip, it is relatively thin (around 2 to 3 mm). Support piece 2, which is made of a metal plate with an appropriate width (about 5 mm) and a relatively long length (about 3000 mm to 4000 mm), and has a perpendicular through hole in the lower end side along the length. A wet filtration machine in which a single metal plate is formed by punching out . It is characterized by a separate elementary field in .

The separation blade plate 1 itself is straight, vertically wavy along its length, or curved either upward or downward to form an appropriate arc shape (see Figures 6 and 7), or an endless ring shape (see Figure 8). ) is optional, and the cross-sectional shape of the separating blade strip 1 between the supporting pieces 2, 2 is arbitrarily formed using a press mold, and each separating blade strip 1, 1 can be formed into various shapes according to its use. Shape separation plate A
It constitutes.

For example, when configuring the separation plate A in a flat shape, a continuous mountain shape, a rectangular tube shape, etc., the straight separation blade plates 1 are arranged in parallel to support each other. ...The connecting pieces 3, 3 are connected to the through hole b by interposing washers 4, 4 with the thickness required for the slit width (approximately 0.1 to 2.5 mm) between them...
. . , and fix the front and rear parts with nuts 5, 5 to form the separation plate A.

In addition, the separation blade plate 1 is formed into a continuous vertical waveform.
- Construct a corrugated separating plate using washers 4, 4, connecting rods 3, 3, and nuts 5, 5 of arbitrary thickness as described above.

Furthermore, it has a curved surface. In the case of a drum-shaped separation plate, an arc-shaped separation blade plate 1 curved upward or downward is used, and washers 4, 4, . Connecting rod 3, 3. Natsu 5,
5 forms a separation plate that can be bent along the slit, and a plurality of arc-shaped separation plates are fixed to the left and right sides of each other, and connecting elbow edges are connected with bolts and nuts to form a drum-shaped separation plate. The flanges fitted to the upper and lower openings are then tightened with beam rods to prevent twisting of the drum itself.

In this case, the support piece 2 of each separation blade plate 1...
... shall face either the inside or the outside depending on its use, and when forming a drum-shaped separation plate, the separation blade plate 1
It is also possible to punch out an endless annular shape as shown in FIG.

In the symbols in the drawing, d and d are pieces of material to ensure an equal width of the slits protruding from the sides of wedges a' and a' of wire rods 1' and 1', which are different from conventional metal wire rods. Also in the separation blade plate 1 of the present invention, if the pitch between the supporting pieces 2 is long, this piece may be provided protruding from the side of the edge portion a.

The separating element of the proposed wet filter has the ability to quickly capture and separate fine particles fused into water in the flow.
Separation blade plate 1. As mentioned above, this is due to the high precision (delicate sharpness) of the edge part a, but by forming the separation element into a single metal plate strip,
By making it possible to use a metal plate in a punched shape, and by taking advantage of the material strength and uniform flatness of the metal plate, it is possible to easily and reliably cut the arrow line with just a few steps. In order to form a sharp and highly accurate separating blade plate 1, and to form a uniform and highly accurate separating plate A surface with such a separating blade plate 1, each separating blade is The most effective condition is to form the strip 1 as a single strip with no seams in the length direction, and it is easy to form a long strip by punching out a metal plate as in the present proposal. I am fulfilling this by doing what I can.

Furthermore, by taking advantage of the properties of punched strips that do not have any unnecessary latent force, and by sequentially erecting the separation blade strips 1 in a blade shape and arranging them in parallel, even, stable, and sharp separation can be achieved. This is an innovative invention that has many elements that have a positive effect on the separation accuracy and separation efficiency of the isohumidity filtration machine, which makes it easy to obtain the A side of the plate.
