However, in conventional equipment, in order to prevent a significant drop in filtration effectiveness due to clogging of the mesh, it is essential to periodically remove the slag adhering to the mesh by backwashing with external water or vibrating the inner cylinder mesh. In addition, in order to reduce the frequency of adhering slag removal work, it is necessary to increase the surface area of the inner cylinder net, which also causes layout problems.

In other words, the gist of the present invention is to make it possible to backwash the inner cylinder screen by switching between multiple chambers and using the water pressure within the system, and to clean the slag adhering to the screen without using external water or vibration force. It is designed to carry out removal work.

By opening only one drain valve 9-1 and closing the other drain valve 9-2, water is discharged from chamber A to the outside of the system via only the drain valve 9-1 and the drain pipe 4-1. The slag is collected on the inner cylinder side wall network 2-1 located in the chamber A.

At this time, the water level in each chamber rises uniformly in both chambers A and B, but when the supply of slurry water is stopped, the stored water passes through the inner cylinder side wall network 2-1 located in chamber A, and drains through the drain pipe 4-1. The slag attached to the inner surface of the inner cylinder side wall network 2-2 located in the chamber B is removed by the backwashing effect of the stored water, and the slag is discharged to the outside of the system via the inner cylinder side wall network 2-2 located in the chamber A. -1 It only adheres to the inner surface.

Next, start supplying slurry water again, open only the drain valve 9-2 and close one of the drain valves 9-1, and the water will be drained out of the system via only the chamber B and the drain valve 9-2. The slag is collected by the inner cylinder side wall network 2-2 of the chamber B. At this time, the water level in each chamber rises uniformly, but when the supply of slurry water is stopped, the stored water passes through the inner cylinder side wall network 2-2 on the chamber B side and is sent to the system via the drain pipe 4-2. Expelled outside. The slag adhering to the inner surface of the inner cylinder side wall network 2-1 on the chamber A side is removed by the backwashing effect of the stored water, and the slag is only deposited on the inner surface of the inner cylinder side wall network 2-2 on the chamber B side of the inner cylinder 2. adhere to. Similarly to the conventional apparatus, the slag is periodically cut out of the system from a hopper 5 at the bottom of the inner cylinder by operating a valve 6.

In this way, by alternately switching between chambers A and B, each indoor tube net is alternately backwashed, so that backwashing from the outside or cleaning of the inner tube net by vibration or the like becomes unnecessary. Furthermore, since the inner cylinder screen is backwashed every time the slag is discharged, the surface area of the inner cylinder screen can be reduced, resulting in a compact device.

As described above, the present invention divides the chamber between the inner tubes of the filtration tank into a plurality of sections, and by switching each chamber for each slag discharge, the inner tube net is alternately backwashed using the head pressure of the accumulated water. The industrial effect of the present invention is great because it eliminates the need for backwashing and allows the device to be made more compact.
