Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for separating a liquid from a solid to which the liquid has adhered.

Conventionally, various types of these technologies are known, such as a compression type and a centrifugal type, but each type requires excessive power or requires the preparation of a large-sized device for the object to be processed. It was uneconomical, had a complicated structure, and was difficult to handle.

SUMMARY OF THE INVENTION Therefore, the present invention aims to eliminate the above-mentioned drawbacks and provide an economical device that has a simple structure and does not require a large amount of power, and its structure will be explained with reference to the following embodiments.

In Figs. 1 and 2, an inner cylinder 3 consisting of a material outlet 1 at the lower part and a screen 2 stretched over the entire circumference or part of the upper wall surface is connected in communication with the inner cylinder 3 in the tangential direction along the upper inner wall surface. The inlet pipe 4 and the inner cylinder 3 surround the outer wall 5 with a distance maintained between them.
An outer chamber 6 is formed between the outer wall 5 and the outer chamber 6, and an exhaust port 7 is provided in the upper part of the outer chamber 6, and a drain port 8 is provided in the lower part of the outer chamber 6. Sometimes they are installed consecutively. The other end of the inlet pipe 4 connected to the inner cylinder 3 is connected to an outside that penetrates the outer wall 5 and is connected to a supply mechanism for the material to be treated (not shown), a blower for air-feeding the material, or piping connected to these. , the exhaust port 7 may be connected to a pipe (not shown) communicating with the next process if necessary.

A screen 2 stretched over the upper part of the inner cylinder 3 is disposed continuously at the point where the inlet pipe 4 is connected to the inner cylinder 3, and forms the wall surface of the inner cylinder 3, and if necessary, covers the entire circumference of the inner cylinder 3. Alternatively, a part of the screen 2 is stretched over the screen 2. The screen 2 is made of a wire mesh, a perforated plate, or a rooster-like member stacked together with slit-like openings in the gaps between the roosters. Inner cylinder 3 of the transferred objects
The liquid that has been subjected to the inertial force of intrusion into the interior or the centrifugal force of rotation is transmitted through the screen 2 to the outer chamber 6.
It is sufficient that the opening size is large enough to allow the solid content to pass through the screen 2. 1
1 supports the component members with support legs, and the design can be changed in various ways depending on the installation location of this embodiment,
Reference numerals 12 and 13 are internal inspection windows made of transparent material, and both are members added as necessary. Material outlet 1
is constructed at the lower end of a continuous sloped wall extending downward from the inner cylinder 3, and is connected to a solid storage tank (not shown) or piping leading to the storage tank, and in either case, it is sealed to prevent gas from passing through. The container will be contacted. In addition, a valve (not shown) may be provided at the drain port 8 and the opening may be adjusted to allow the separated liquid to flow out but not gas, or a general trap-shaped valve may be used to prevent gas from passing through. It may also be configured to allow only the liquid to flow out. 14a,1
4b is a band-shaped weir that is added along the inner surface of the inner cylinder 3 (if necessary), and small diameter openings 15a and 15b are bored in several places inside the inner cylinder 3 on the top surface of each weir, and the inside of the outer chamber 6 and the inside are connected. The inside of the cylinder 3 is communicated with the weir 14a, 1.
This is for guiding the liquid deposited on the surface 4b to the outer chamber 6. In addition to the above, the screen 2 has openings B that face the outer chamber 6 in a direction opposite to the direction of the airflow in the inner cylinder shown by the arrow, as shown in the screen 2b shown in FIG. It is also possible to have a structure that allows the solid content to pass through, but makes it difficult for the solid content to pass through.

In the above configuration, the material to be processed is fed vigorously in the tangential direction along the inner wall surface of the inner cylinder 3 through the inlet pipe 4 using a supply device for the material to be processed and the blower (not shown), and the gas and liquid components of the material to be processed are separated. The liquid passes through the screen 2 and reaches the outer chamber 6 due to the inertial force of entering the inner cylinder 3 or the rotating centrifugal force, and the liquid flows through the screen 2, the outer wall surface of the inner cylinder 3, and the inside of the outer wall 5 due to gravity. The gas descends along the wall surface or settles in the space inside the outer chamber 6, collects at the drain port 8, and is taken out of the machine. It is released outside or sent to the next process. The solids that cannot pass through the screen 2 descend along the inner wall surfaces of the screen 2 and the inner cylinder 3 due to the airflow swirling inside the inner cylinder 3 and the weight of the accumulated solids, collect at the material outlet 1, and are discharged outside the machine. Ru. In addition, a small amount of liquid that adheres to the solids and has not been filtered and separated descends along the inner wall surface of the inner cylinder 3, and is received by the upper surface of the weir 14a or 14b and the opening 1
5a and 15b into the outer chamber 6, and joins with the liquid that has passed through the screen 2. In order to minimize the amount of solid matter deposited on the upper surface of the weirs 14a and 14b, the dimensions of the weirs are made small, and the small weirs 14a and 14b are able to sufficiently absorb the liquid that descends on the inner surface of the inner cylinder 3 and prevent the outer chamber 6. It can be separated into The apparatus of the present invention may be directly connected in several stages to repeatedly perform the separation operation, or may be used in combination with other types of separators.

As detailed above, according to the present invention, there are no moving parts in the device, and solids and liquids can be separated by simply installing a general blower and a feeder for the material to be treated. The present invention is industrially very useful because it is simple and economical because it can be implemented at low cost without requiring a large amount of power, and because the entire device is lightweight and easy to relocate.
