Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concentrating centrifuge for feeding the deconcentrated sugar discharged from the concentrating centrifuge to a vibrating conveyor for the next drying step in the concentrating process of a sugar manufacturing plant. The present invention relates to a chute device for a separator.

[0002]

2. Description of the Related Art Generally, sugar which has been deconcentrated is sent to a vibrating conveyor through a cylindrical chute connected to an outlet of a basket of a concentrating centrifuge (see, for example, Japanese Utility Model Publication No. 57-60720). .

[0003]

By the way, the sugar immediately after being mashed has a moisture content of 2 to 3% and a temperature of 40 to 80 ° C.
Therefore, it is usually called wet sugar, but when the wet sugar adheres to the inner wall surface of the cylindrical chute, the temperature is high, so that water immediately evaporates and it is difficult to solidify and remove it. Not only that, but there was a risk that the adhered and solidified sugar would accidentally fall off and mix into the product. For this reason, in the conventional device, it was necessary to periodically scrape off and clean the sugar adhering to the inner wall surface of the cylindrical chute. Moreover, this removal work is very troublesome and time-consuming.

Further, the conventional apparatus has a problem that sugar is scattered to the outside of the vibrating conveyor by the wind blown from the lower end opening of the cylindrical chute together with the sugar fed into the vibrating conveyor.

The present invention has been made in order to solve the above-mentioned conventional problems, in which the succulent sugar does not adhere to the cylindrical chute, and the sugar is produced by wind blown from the lower end opening of the cylindrical chute. It is an object of the present invention to provide a chute device of a centrifuge for syrup that can effectively prevent the scattering of honey.

[0006]

In order to achieve the above object, the present invention has a cylindrical chute connected to an outlet of a basket of a concentrating centrifuge, and vibrates below the cylindrical chute. In the mashing process of a sugar production plant in which a conveyor is arranged, the tubular chute is made of a tough and flexible material such as nylon or rubber, and the lower end opening edge of the tubular chute is the vibrating conveyor. It is connected to the side plate of.

[0007]

The cylindrical chute resonates in conjunction with the vibrating conveyor and effectively vibrates due to its flexibility, so that it is sent to the vibrating conveyor through the cylindrical chute. Even if succulent sugar (wet sugar) adheres to the inner wall surface of the shoot, it is immediately shaken off. Further, the wind blown from the lower end opening of the cylindrical chute together with sugar is blocked by the both side plates of the vibrating conveyor and blows in the conveying direction of the vibrating conveyor.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a syrup centrifuge 1 for a sugar production plant equipped with a chute device according to the present invention, in which a casing 2 has an input port 3 at an upper portion and an inclined bottom plate 4 at a bottom portion. A sugar-tight outlet 5 is provided.

The basket 6 has a large number of through holes 7 on its side wall, a discharge port 8 is provided at the bottom, and a plurality of arms 10 having bosses 9 radially arranged at the center of the discharge port 8. It is provided to support. Then, the upper end of the rotary shaft 11 fitted and fixed to the boss 9 is interlockingly connected to a rotation driving device (not shown), and the basket 6 is arranged in a suspended state in the casing 2.

The lid 12 of the discharge port 8 is movably supported on the lower end of a cylinder shaft 13 slidably fitted on the rotary shaft 11, and moves the cylinder shaft 13 upward as indicated by an imaginary line. By doing so, the discharge port 8 is opened.

A cylindrical body 14 for attaching a cylindrical chute 20 described later is fixed to the bottom plate 4 of the casing 2. The cylindrical body 14 is arranged concentrically with the discharge port 8 so as to surround the discharge port 8, and a flange portion 15 is provided on the outer periphery of the lower end opening.

The cylindrical chute 20 is formed into a cylindrical body from a composite material in which vinyl chloride is attached to the surface of a sheet-shaped core material made of nylon, and is strong and flexible. As shown in FIG. 3, the cylindrical chute 20 has an upper end opening 21 having a circular shape having substantially the same diameter as the cylindrical body 14, and an annular folded portion 2 corresponding to the flange portion 15 on the outer periphery thereof.
2 is formed. On the other hand, the lower end opening 23 is formed in a square frame for connecting to both side plates 31, 31 of the vibration conveyor 30 described later, and the folded portion 2 is formed along the four sides of the outer periphery thereof.
4, 24 and folded portions 25, 25 are continuously provided.

The vibrating conveyor 30 is disposed below the discharge port 8 and the cylindrical body 14 and extends horizontally as shown in FIG. Flange portions 32, 32 bent outward are provided at the upper ends of both side plates 31, 31 of the vibration conveyor 30.

Thus, the upper end opening 2 of the cylindrical chute 20.
1 is fixed by sandwiching the folded-back portion 22 between the flange portion 15 and the circular pressing frame 16 corresponding to the flange portion 15, and is connected to the cylindrical body 14 in a communicating state. On the other hand, the lower end opening 23 of the cylindrical chute 20 includes a rectangular holding frame 26 having a rectangular shape surrounding the lower end opening 23 and the flange portions 32 of the vibration conveyor 30.
By sandwiching and fixing with 32, the vibration conveyor 3
0 is connected to both side plates 31, 31. At this time, the folded-back portions 25, 25 facing each other are located above the conveying surface of the vibration conveyor 30 in a free state.
It is fixed by being sandwiched between 6.

In the above structure, the basket 6 is separated into sugar crystals and molasses by centrifugal force due to high speed rotation, and the sugar crystals accumulated in the basket 6 are discharged from the outlet 8 to the vibrating conveyor 30 through the cylindrical body 14 and the cylindrical chute 20. Send in,
The vibrating conveyor 30 conveys the chute 20 to the next drying step. The cylindrical chute 20 resonates in conjunction with the vibrating conveyor 30 and is flexible so that it vibrates effectively and becomes cylindrical. Even if sugar crystals fed to the vibration conveyor 30 through the chute 20 adhere to the inner wall surface of the chute, they are immediately shaken off and do not adhere to the inner wall surface of the chute and solidify. Further, the wind blown out from the lower end opening of the cylindrical chute 20 together with the sugar crystals is blocked by the both side plates 32, 32 of the vibration conveyor 30 and blows out in the conveyance direction of the vibration conveyor 30, so that the sugar blows off the sugar. Effectively prevented.

[0017]

As described above, according to the present invention,
Since sugar does not adhere to the inner wall surface of the cylindrical chute, cleaning of the chute becomes unnecessary or easy, which not only saves manpower but also improves the operation rate of the concentrating centrifuge.

Further, since the lower end opening edge of the cylindrical chute is connected to both side plates of the vibrating conveyor, it is possible to effectively prevent the scattering of sugar due to the wind blown out together with the sugar from the lower end opening. Also, it is convenient in terms of operation management.
