Abstract

PURPOSE:To perform efficient centrifugal separation without plugging a tubular body with ice, by annexing scrapers to the tubular body, and connecting them through a gearbox to a driver means. CONSTITUTION:Four scrapers 29 provided oppositely to the inner surface of a wire net 23 with the same angles are supported through pipe-shaped blankets 30 at the upper and lower positions of a shaft 28 coaxial with the hollow shaft 19 of a tubular body 21. The hollow shaft 19 and the shaft 28 are connected through bevel gears 34, 35 to the gear group 36 and the motor 37 of a gearbox. Thus, ice parts adherent onto the wire net 23 by centrifugal force are sequentially peeled off by the scrapers 29, so as to continually maintain the power of separation.

Description

DETAILED DESCRIPTION OF THE INVENTION The disclosed technology belongs to the technical field of centrifugal separators for concentrating ice-containing water bath liquids and the like.

1-However, the invention of this application includes a separation main body having a supply port for a water bath liquid containing ice or the like, or a cylindrical body with a predetermined mesh connected to a drive device, and L- supply [ ]. This invention relates to a centrifugal separator that faces the inside of a cylindrical body and has a scraper in contact with the cylindrical body to scrape off adhered substances to be treated. The scraper is made to be able to rotate with a relative speed difference in the same direction, and the scraper has a sliding force on the cylinder, or a set clearance via a roller that rolls into contact with the cylinder. This invention relates to a centrifugal separator that is disposed opposite to a cylindrical body in a non-contact manner.

In general, centrifuges are widely used in various industries as devices that perform separation operations such as sedimentation, precipitate concentration, filtration, and dehydration using the centrifugal force generated by rotation. It is sometimes used as a condensing device by removing all the water content.

By the way, when removing the moisture from the food mentioned above.

In order to avoid food denaturation due to heating and to increase separation efficiency, semi-freezing concentration is used to separate water under low temperature conditions. □ For example, when calling a solution in a juice, the water in the aqueous solution is frozen into a sherbet state, which is then centrifuged to separate the juice solution from the ice and concentrate. It will be done.

At this time, the liquid water content of the sherbet supplied from the input port of the centrifuge is separated to the outside by the rotation of a predetermined mesh cylinder built into the main body of the centrifuge.
The problem with glue that separates frozen components inward is that the ice in the sherbet gradually adheres to the inner wall of the cylinder, including the mesh part, forming an ice film and blocking the mesh, reducing separation efficiency. was there.

As a result, operation must often be stopped to scrape off ice, resulting in extremely low operating efficiency.

To deal with this, a centrifugal separator was devised in which a fixed type scraper is placed in contact with the inner surface of the cylindrical body, and the attached ice film is continuously removed by the difference in relative high speed rotation between the scraper and the high speed rotating mesh part. However, as mentioned above, since the cylinder rotates at high speed, the load on the stationary scraper and scraper is large, and 1. Since the scraper was in contact with the cylindrical body, there was a problem in that the scraper and the cylindrical body interfered with each other, potentially damaging the mesh part.

Therefore, scraping cannot be done reliably, and the inner wall of the cylinder must be cleaned periodically, resulting in continuous operation 1□-:
■ There was a problem that made it difficult to remove.

Furthermore, the inner surface of the cylindrical body 9 above is partially 0, and < , r, ,,
It is difficult to maintain a constant gap between the V□ and the cylindrical body because it is difficult to make a perfect circle.So, it is not possible to make the scraper always set a constant scraping distance. There were also some inconveniences.

The purpose of the invention of this application is to solve the problems of the centrifugal separator based on the above-mentioned prior art, and to prevent the ice that inevitably adheres to the inside of the cylinder from clogging the mesh part, and to achieve a continuous separation function. It is an object of the present invention to provide an excellent centrifugal separator that maintains a constant separation efficiency and is useful for separation applications in the fluid processing industry.

The structure of the invention of this application, which is full of the above-mentioned objects and whose gist is the above-mentioned claims, is to solve the above-mentioned problems by using a water-containing liquid component introduced into the upper supply port of the separation main body via a conveying device. When the liquid component is pressed against the inner surface of the rotating cylinder by centrifugal force via a drive device installed in the separation main body, the liquid component is separated and separated to the outside of a predetermined mesh of the mesh part of the cylinder, and is released outside the machine. On the other hand, the liquid component of the water that is pushed and forced onto the inner surface of the cylinder is sufficiently separated.
Even if the water tries to adhere to the inner surface of the cylindrical body, a scraper rotating at a relative speed in the same direction as the cylindrical body via the drive device mechanically peels off and removes the adhered ice film. , the scraper is always held directly on the inner surface of the cylindrical body or indirectly through an attached roller with a set clearance, and furthermore, it is always opposed to the inner surface of the cylinder through a compression spring. The separated liquid component is substantially discharged outside the machine as a concentrated liquid and connected to the next stage process.

Next, embodiments of the invention of this application will be described below with reference to the drawings.

FIG. 1 shows a centrifugal separator 1 constituting the gist of the invention of this application.
- It is used for a splint, and is mounted and fixed on a base 5 via legs 4 serving as a lower bracket of a bottomed cylindrical separation main body 3 connected to a cariveyor 2. , .

are attached on all sides, and a pulp 16 is provided at the outlet 15 of the inner sole 10. , 1°, and a seal ring 18 is provided inside the separation body 3 on a bearing ring 17 attached to the center of the bottom 6 of the separation body 3, and is supported by inserting the core bearing. A cylindrical body 21 is fixed to the hollow shaft 19 via a honeycomb bracket 20.

Thus, the nuclear cylinder 21 has a plurality of vertical ribs 22, 22...
It has a cylindrical wire gauze 23 with a predetermined mesh 17, and an upper lid 25 having a supply port 24 is integrally formed in the circular upper part.

The conveyor 2, which is connected to the u) youth soap manufacturing device 26, faces the supply port 24 at the center of the upper lid 25.

In addition, the lid 25 and the honeycomb plate I.
The rubber rollers 14, 14, .

However, a cover 27 is provided above the bearing 17 and seal ring 18.

(-) A shaft 28 is installed concentrically in the inside of the empty shaft 19, and the shaft 28 engages four scrapers 29, 29, etc. of a conformal device that is in contact with the inner surface of the wire mesh 23. It is supported at the upper and lower portions of the shaft 28 via pipe-shaped brackets 30.

Each of the scrapers 29 is opposed to the wire mesh 23 with a set clearance provided by rubber rollers 31, 31, .

In addition, in the center part of the upper bracket 30, the supply "
124, a conical dispersion cone 32 is integrally attached to the center of the lower bracket 30, and a similarly truncated cone-shaped dispersion cone 33 is integrally attached.

Only 1 ㅅ, - hollow above! The sleeve 19, the shaft 28 and the bevel gear 34.3 are integrally attached to the lower ends of each.
5, it is connected to a motor 37 on the base 5, which is linked to a gear group 36 as a transmission.

The hollow shaft 19 and the shaft 28 are configured to rotate in the same direction through the gear group 36 at a set speed difference.

Further, a universal joint 38 is interposed at the lower part of the shaft 28.

In the configuration described above, the motor 37 is fully driven: The hollow shaft 19 and the shaft 28' are rotated through the gear group 36 and the bevel gear 34, 35 in the direction of the arrow in the figure through a set relative speed difference. I'll let you.

Therefore, the cylindrical body 21 rotates inside the separating body 3 via the rubber roller 14, and each scraper 29 inside the cylindrical body 21 rotates in the same direction as the cylindrical body 21 with the rubber roller:
1, thereby said scraper 29
rotates with respect to the cylindrical body 21 with a speed difference of one phase.

As shown in FIG.
1. When the workpiece 40, which is carried out from the Sherbela and has one side, is put into the supply [24], 1. Nuclear processing object 40
are uniformly separated in the circumferential direction by the rotating dispersion cones 32 and 33, and are pressed against the wire mesh 23 of the rotating cylinder 21 via centrifugal force.

At this time, moisture gradually arrives on the wire mesh 23F,
[] Even if you try to remove the jammed metal, the scraper 29 will sequentially peel it off and remove it, so the separation function will always be maintained.
Therefore, the efficiency does not decrease, and since the clearance between each scraper 29 and the wire mesh 23 is always kept constant via the rubber roller 31, the scraper 29
9, 23 pieces of wire mesh were to be returned under constant conditions.
Unfortunately, interference between the two due to rotation will be prevented.

In addition, universal join)・38 has a yacht, axis 2
Even when the shaft 8 rotates eccentrically, the rotational force is transmitted to the shaft 28 without any force being applied.

The treated J414 proboscis 40 is sequentially supplied as described above.
However, by allowing the frozen moisture to participate in the separation, □
, a predetermined concentrated liquid component is obtained from the discharge valve 16.

Next, in the second embodiment shown in FIG. Since the rubber roller 31 of each scraper 29 is always pressed against the wire mesh 23, the scraper 9 and the wire mesh 23 are constantly pressed against each other. The clearance with the wire mesh 23 is securely maintained without being changed even by rotational vibration. □In addition,
It goes without saying that the embodiments of the invention of this application are not limited to the above-mentioned embodiments. For example, a punching plate, a metal lath plate, etc. may be used instead of a wire mesh, or a heater may be attached to a scraper to perform peeling. It may be heated and melted at the same time as separation, and an air damper may be used in place of the above-mentioned spring to attach the scraper.
In addition, a continuously variable transmission device is installed in the gear group to adjust the relative speed between the scraper and the cylinder according to the properties of the workpiece, and a clearance adjustment device between the scraper and the cylinder surface is installed. or make the rubber roller removable so that it can be replaced with one with a different outer diameter.

Various methods can be adopted, such as freezing and concentrating seawater using cold energy, and converting the water separated at that time into M, which can also be used in the seawater desalination industry.

According to the invention of this application as described above, the deposits on the inner surface of the cylindrical body of a predetermined mesh are basically scraped off using a scraper, so that even if the cylindrical body becomes clogged during operation, the operation can be continued. Continuous operation is possible without any stoppage, and it is possible to maintain the same amount of time and function as long as possible, improving separation efficiency and separating the objects to be processed. is played. □Also, does the scraper have a relative speed in the same direction as the cylinder to enable N rotation? c'q+
=・Compared to the fixed scraper type, the negative force caused by mutual interference between the cylinder and the scraper is small, and as long as this is possible, the scraper and wire mesh can be prevented from being damaged.

Furthermore, since the scraper has a preset clearance via a roller that rolls into contact with the cylinder, it is possible to maintain a constant scraping condition between the scraper and the cylinder, thereby removing the deposits. It has an excellent effect of being able to reliably scrape off.

Furthermore, since the scraper is biased against the cylindrical body, an excellent effect can be achieved in that the scraper can be brought into contact with the cylindrical body more reliably by following the rotation of the cylindrical body.

In addition, the cylindrical body does not become clogged during operation, and continuous operation is possible, resulting in increased throughput and reduced operating costs.
