is a power transmission mechanism, and 42 is a cleaning brush. Now, when the main shaft of the electric motor 40 is rotated, the screw rotates and performs vertical movement and rotational movement at the same time. The rotation of the main shaft is transmitted by a friction contactor of F4.
1. When the cleaning brush 42 is lowered to a predetermined position, the friction contactor F operates a contact/non-contact switch B to reverse the rotation of the transmission 40, thereby raising the brush. Similarly, the electric motor 40 is rotated in the reverse direction using switch A, and the cleaning brush 42 is lowered. Add up the number of times switch A or switch B is activated using a counter not shown,
When the predetermined value is reached, the power switch is activated to stop the electric motor.

This figure shows a mechanism for cleaning clogging of the filter by emitting light onto the outer surface of the filter 30 through the porous nozzle plate 45. The porous nozzle plate 45 has the function of diffusing the gas from the jet nozzle 44 . The solid waste brushed off the inner surface of the filter 30 is discharged from the outlet 46.

Next, the action of this drain pot will be explained.
This draining pot is now fixed to the lowest part of a liquid container (not shown) in the state shown in FIG. 1, and at this time, both the draining pots 8a and 26 are assumed to be in a fully open state. In such a state, chamber A of rotor 9 has hole 1.
Since it communicates with the inside of the container through the opening 1 and the attachment port 14, waste such as solid sludge generated inside the container accumulates in the lower part of this chamber A.

After a certain period of time has elapsed, turn the drive ring 21, and the large gear 1
9. If the rotor 9 is rotated by a predetermined angle via the small gear 17 so that the notch _A1 corresponds to the effective liquid outlet 5 and the chamber A is communicated with the effective liquid outlet 5, the effective liquid can be collected via the The waste is only solid matter. If you change the position of this to room C, hole 6 of lower box 1 of room C
The solids are discharged from the system. In addition, the above 32
The filtering surface 30 is cleaned by the brushing or vibrating mechanism, and the waste is taken out of the system through the next outlet 6.

Next, rotate the drive ring 21 in the same direction to rotate the rotor 9.
If the notch _A1 is made to correspond to the waste outlet 6 and the chamber A is communicated with the waste outlet 6,
The waste accumulated in the chamber A is discharged and removed to the outside through the discharge port 6, and the notch _C1 is opposed to the drain discharge port 5, so that the oil in the chamber C is opposed to the drain discharge port 5. Then, the oil in the chamber C passes through the drain outlet 5, the filter 23 and the oil draining pot 26, and is recovered to the outside.

At this time, the waste adhering to the filter 30 is removed by the waste liquid recovery mechanism shown in FIG. First, liquid or gas is injected from the jet port 44 toward the center of the filter, and the filter 30
During filtration, a flow is generated in the opposite direction. Then, the solid matter adhering to the edges of the filter 30 is brushed off. Next, the brush body 42 is rotated by the electric motor 41 and lowered (in the case of horizontal installation,
) to forcibly shake off the waste adhering to the inner surface. The brushed off waste is taken out from the outlet 46.

Further, since the chamber B is communicated with the inside of the container through the hole 11 and the attachment hole 14, waste materials remaining inside the container are precipitated and accumulated. Therefore, by rotating the rotor 9, waste can be discharged.

By repeating the same operation as described above, the waste inside the container is precipitated and accumulated in the chamber A that communicates with the inside of the container through the hole 11 and the attachment port 14, and the drain is removed. The chamber B corresponding to the discharge port 5 has a lower notch _B1 and a filter 23.
The oil is discharged to the outside through the discharge port 6, leaving behind waste, and the chamber C corresponding to the waste discharge port 6 is emptied as the waste is discharged to the outside through the discharge port 6.

In this way, waste can be efficiently discharged from the inside of the container by only rotation by the rotor 9 without interrupting the oil cooking operation or replacing the oil.

Although the above embodiments have been described with respect to the case where the drain sockets are arranged in the vertical direction, the same effect can be obtained without being limited to this, and the same effect can be obtained even if the drain sockets are arranged in the horizontal direction.

(Effects of the invention) As explained in detail above, the drain tank according to the invention divides the inside of the rotor into a plurality of compartments, and uses these compartments sequentially to remove waste from the fluid while interrupting work. It can be removed without removing it. Moreover, by using brushing and vibrating high-pressure gas, solid-liquid separation can be promoted on a fresh filtration surface. Since it is removed by the filter cleaning mechanism, clogging of the filter can be prevented.
