Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention comprises a main body having a substantially cylindrical shape, and a tapered cone joined to the main body,
When the material to be processed is fed tangentially to the main body, relatively fine particles are separated from the upper part of the main body, and relatively coarse particles are separated, concentrated and discharged from the lower part of the cone. This is about cyclones, which are becoming more common.

``Prior art j Cyclones used as classifiers, collectors, purifiers, concentrators, etc. for fine particles are well known in the past, needless to mention the names of literature, and generally have a cylindrical part and a tapered part. It is integrally formed with the cone part, and its material is steel.

Therefore, when the material to be treated, for example slurry, is fed tangentially into a cylindrical part, the slurry swirls in the cyclone, and due to the difference in centrifugal force, relatively fine particles are transferred from above the cylindrical part as an overflow, and compared to Coarse particles are separated and discharged as an underflow from below the cone.

``FF Problem to be Solved by the Invention'' By the way, even if a cyclone is integrally formed from a cylindrical part and a cone part as in the past, when it is used in mining etc. do not have. However, when used in the food industry, there are problems. In other words, food processing machines need to be washed with water after each operation to keep them sanitary, but it is difficult to wash a cyclone with a one-piece structure. In addition, rust is likely to occur, making sanitary management difficult.

Therefore, recently, a cyclone has been proposed in which the cyclone is divided into two parts and these parts are fixed with bolts via a flange. However, the type that is fixed via a flange requires 4 to 6 bolts, and it is inefficient to remove these bolts, wash them with water, and then re-tighten them. This is painful for workers who are tired at the end of the day's work.

Therefore, an object of the present invention is to provide a cyclone that can be applied to the food industry, that is, a cyclone that is resistant to rust and that can be easily washed with water to promote good sanitary conditions.

"Means for Solving the Problems" In order to achieve the above object, the present invention comprises a main body section having a substantially cylindrical shape, and a tapered cone section joined to the main body section. When the material to be processed is fed tangentially to the main body, the relatively coarse material is separated or concentrated from above the main body, and the relatively coarse material is separated or concentrated from below the cone. In the cyclone, at least the main body and the cone are formed separately from rust-free steel, and these are tapered in a tapered shape toward the outside of the radius. The main body portion and the cone portion are connected and integrated by being tightened by a clamp configured to be operated with a single bolt.

"Function" According to the present invention, the main body and cone of the cyclone are formed separately from rust-free steel, but if the ferrules of these are integrated with a clamp, the slurry It is possible to perform processing such as classification and concentration of objects to be processed. In other words, when the material to be processed is fed tangentially into the cylindrical part, the material to be processed rotates within the cyclone, and due to the difference in centrifugal force, the relatively large particles are transferred from above the cylindrical part as an overflow, and the relatively Coarse particles are separated and discharged as an underflow from below the cone section.

When you want to wash or inspect the inside of the cyclone, loosen the clamp bolts that tighten these ferrules. Then, the main body part and the cone part are separated into two parts. Therefore, the inside can also be easily washed away. After washing with water, tighten the ferrule on the main body and the ferrule on the cone with a clamp to complete the morning stand.

As described above, according to the present invention, the cyclone can be disassembled and assembled by simply tightening or loosening one bolt, so hygiene management can be easily performed when applied to, for example, the food industry, where frequent washing with water is required.

"Example" In carrying out the present invention, the cyclone can be implemented so that parts other than the main body and the cone can be separated. The accompanying drawings therefore show an example of implementation in four parts. Furthermore, when implementing this method, it is desirable to apply a gasket to the ferrule.

This is because watertightness is maintained.

One embodiment of the present invention will be described below. Now, referring to FIG. 1, it will be easily understood that the cyclone of this embodiment has a similar external shape to that of the conventional cyclone. That is, the cyclone S includes a cylindrical main body part 1, a tapered cone part 2, a nozzle part 3 which is also tapered, and a lid provided with an overflow pipe 4. It consists of section 5. These are then integrated by tightening their respective ferrules as detailed below.

The main body l, like the other elements, is made of stainless steel (registered trademark), that is, rust-free steel, and a foot tube 6 is provided in the tangential direction thereof. Ferrules 10.10 are integrally formed at both the upper and lower ends. ferrule 1
0 is the end face 11 as shown enlarged in FIG.
is horizontal, but the other surface 12 is tapered radially outward. An annular groove 13 is formed in the end surface 11, and a ring-shaped gasket is inserted into this groove.

A ferrule is also formed at the upper end of the cylindrical main body 1,
Further, ferrules are formed at both the upper and lower ends of the cone portion 2, as well as on the nozzle 3 and the lid portion 5, but these ferrules are structurally the same as the ferrules described above, so please refer to the same ferrules. A redundant explanation will be omitted by adding a symbol.

A clamp 20 that integrally tightens the ferrules 10 and 10 of the main body part 1, cone part 2, etc., which are the components of the cyclone.
As shown in FIG. 3, it is composed of a first semicircular arc member 21, a second arc member 22, a bolt 23, and a butterfly nut 24.

As shown in FIG. 4, the cross sections of the first arc member 21 and the second arc member 22 are narrow at the center and wide at both sides. These arcuate members are then pivotally connected at one end by a pin 25.

The arcuate members 21 , 22 can therefore be spread out about the pin 25 . The other ends of the arcuate members 21, 22 are formed with slits larger than the diameter of the bolts 23, as shown in FIG. has been done. The bolt can therefore pivot about pin 26 as indicated by arrow a in FIG.

Since the clamp 20 is constructed as described above, in order to assemble the cyclone using this, first loosen the butterfly nut 24, rotate the bolt 23 around the pin 26, and insert the slit in the first arc member. Remove from. Then, the other arcuate members 21 and 22 become free and spread out around the pin 25. Then, as shown in FIG. 2, the ferrules 10.10 are combined or overlapped, and the first arc-shaped member 21 and the second arc-shaped member 22 are combined to form the ferrule 10. Sandwich IO. Then, insert the bolt 23 into the slit of the first arc-shaped member and tighten the nut 24. Then, the arc-shaped member 21.
22 moves in the central direction C as shown in FIG. Since the outer portion of the ferrule 10.10 is tapered, the ferrule moves in the thrust direction shown by arrows S and S, and both ferrules 10.10 are tightened. That is, the main body portion 1 and the cone portion 2 are joined and integrated. Thereafter, the supply pipe 15 is also assembled in the same manner. It is clear that the decomposition can be done by the reverse procedure.

Since the cyclone according to the present embodiment is configured as described above, for example, when a slurry-like semi-finished filling obtained by boiling and crushing beans such as red beans and green beans is fed to the main body 1 from the feed pipe 6. The bean paste is rotated in the main body part 1 and the cone part 2 to be classified or concentrated, and the bean paste as a product can be obtained from the nozzle 3.

When it is necessary to wash with water, the bolt 23 of the clamp 20 is loosened and the clamp is removed from the ferrule 10.10, so that it can be disassembled into the main body part 1, cone part 2, nozzle 3, lid part 5, etc. Therefore, washing with water becomes easy. Assembly is also easy, just tighten one bolt 23.

According to this embodiment, since the cyclone can separate both the lid part 5 and the nozzle 3, cleaning work can be done more easily and efficiently.

"Effects of the Invention" As detailed above, according to the present invention, the main body section having a substantially cylindrical shape and the cone section having a tapered warp are formed from rust-free steel, so that they will not rust. Therefore, it is suitable as a cyclone for the food industry. In addition, the main body and cone have ferrules, and these ferrules are assembled using a clamp with one bolt, so disassembly and assembly can be easily done with just one bolt. Therefore, it is easy to wash with water, which is an advantage unique to the present invention.

As shown in the second point, since the cyclone can be easily washed with water, good sanitary conditions can be maintained, making it suitable as a cyclone for the food industry.
