DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of inserting / removing an object to / from a centrifuge, which facilitates the inflow / outflow of the object to / from the centrifuge, and improves the operating rate of the centrifuge. About the trolley.

[0002]

2. Description of the Related Art There are a centrifugal dehydrator and a centrifuge (hereinafter referred to as "centrifuge") as a device for separating and dewatering water contained in a product. This centrifuge is useful for controlling the amount of water contained in the product as appropriate by controlling the rotation speed and the operation time. FIG. 1 shows a cross-sectional view of the centrifuge. In the figure, reference numeral 1 denotes a cylindrical casing, and 2 denotes a basket for removing moisture absorbed by centrifugal force by rotating a material to be separated accommodated in the casing 1 at a high speed. Are provided with a large number of outlets for discharging the drained water. 3
Is rotationally driven by a motor 6 to be described later integrally with the basket 2 on a main shaft. A motor 6 for rotating the main shaft 3 is transmitted through a belt 8 and a pulley 10. 4 is the casing 1 and the motor 6 described above.
A frame that supports the main body of the air conditioner and the like.
5 is installed. Reference numeral 5 denotes an opening / closing lid for taking in and out the object to be separated, which is closed during operation to prevent the contents from jumping out. In the above configuration, the operation is performed in the following manner to perform a dewatering operation of an object to be separated (hereinafter referred to as “product”).

[0003] That is, in the basket 2 of the centrifugal separator, products are placed one by one with the main shaft 3 as a center or in units of a lump of an appropriate size in a well-balanced manner. 6, the basket 2 is rotated, and when the rotation of the basket 2 is accelerated and becomes constant, the brake 11 is applied after a predetermined time has elapsed, and the driving is stopped. And
After the basket 2 stops, the lid 5 is opened to take out the drained product.

Since this series of operations is a batch process, the product must be temporarily stocked while the centrifuge is rotating. However, porous materials such as sponges and cloths vary in size and shape depending on the type of product, and therefore liquid supply, liquid removal, washing, and scraping as used for granules and powders. It is not possible to use a hermetically sealed centrifuge that can continuously perform the picking process by pipe transport.
Therefore, these products have to use a batch type centrifugal separator, and must be put in and out each time of processing.

On the other hand, in sponge products, FIG.
As shown in (1), after the product cut into a predetermined size and shape is washed with water (100), dehydrated (101), the product is subjected to an antifungal liquid impregnation treatment (102) such as a softener, a preservative, and an antifungal agent. After doing
This is again drained (103), and the products after draining are spread one by one, folded to the product packaging dimensions (104), and packed (10).
5) Shipped. Therefore, in the case where the centrifuge is used many times until the product is completed as in the case of the product, it is necessary to put the product into and out of the centrifuge each time.
In the method of handling products one by one and going in and out,
This takes a lot of time and significantly reduces the operation rate of the centrifuge.

Therefore, as a method of shortening the time for putting in and taking out the product, the product is put in advance in a cart having an external dimension which can be put in a basket of a centrifuge, and this cart is inserted into the centrifuge. Then, a method of greatly reducing the work time has been proposed.

[0007]

However, since the basket of the centrifuge rotates at a high speed, it is necessary to make a cart that is functionally lightweight and balanced.
Further, it is necessary to make the inner wall part thin so that the inner volume of the basket can be used as effectively as possible. On the other hand, since this bogie is used many times, it does not lose its balance and requires a function that is sufficiently strong and contradictory to the above, so it is difficult to realize it structurally. It will be expensive. In addition, the product to be mounted next is put in advance in the cart and prepared, and this cart is sequentially replaced to efficiently perform the liquid removal work. For that purpose, wheels are provided so that the cart can move freely. However, it is inevitable that the truck has no wheels from the viewpoint of securing the product accommodation space and the balance, and there is a problem in the movement between the trucks at the time of switching.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has a centrifugal separator capable of stocking using a bogie having rough manufacturing accuracy with wheels and securing a product storage space equivalent to that of a basket. It is an object of the present invention to provide a method of inserting and removing an object to be separated from a machine and an auxiliary cart thereof.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to provide a bogie having an inner wall formed in substantially the same shape as that of an object to be accommodated in a centrifugal separator, and having both ends open at each end. A cylindrical mesh bag provided with a string for closing the opening portion, and the mesh bag having an open top portion and a closed bottom portion is placed in a cart, and after the object to be separated is stored in the mesh bag, Centrifugal separation in which the upper opening of the mesh bag is closed with the bottom string protruding from the upper opening, and the object to be separated is centrifuged by putting the mesh bag into a centrifuge as it is. This is achieved by a method of inserting and removing an object to be separated from the machine.

[0010] Further, the bogie used for this has a plurality of discharge holes for discharging the separated liquid in the inner wall portion thereof, and wheels are provided at a lower portion thereof.

[0011]

According to the method of inserting / removing a product into / from the centrifuge according to the present invention, a bogie having an accommodating portion having substantially the same shape as the basket of the centrifuge is provided, and a string for closing the opening is provided at both ends. A tubular mesh bag is provided, and the mesh bag is closed only in the bottom portion and placed in a cart. After the product is stored in the mesh bag in a well-balanced manner, the bottom strap is pulled out from the upper opening. The upper string of the mesh bag is closed, and this portion is suspended and inserted into the basket of the centrifuge.

Therefore, only the net bag containing the product is placed in the basket of the centrifugal separator, so that the space for storing the basket can be fully utilized and the overall balance can be corrected by adjusting the bottom of the net bag. The product can be easily corrected with just a little lifting, and the product after draining can be easily taken out by taking out the net bag and unwinding the lower string, greatly saving labor for entering and exiting work. Not only that, the operation rate of the centrifugal separator can be remarkably improved due to the quicker access of the product.
