構造である。2. Description of the Related Art Solid-liquid separators utilizing centrifugal force are known per se, and there are several types such as a cyclone type.
Among them, as a typical apparatus having excellent performance for separating solid particles and the like contained in a liquid, there is a solid-liquid separator as shown in FIG. The solid-liquid separator 10 includes outer barrels 14 and 16 at upper and lower portions of a separation cylinder 12, respectively.
And an inlet 18 on the side of the upper outer barrel 14,
In addition, the appearance structure is such that an outflow pipe 20 is disposed through the upper surface of the outer barrel 14 from above in the separation cylinder 12 to provide an outlet 21, and a solid discharge port 22 is provided below the lower outer barrel 16. .

出する。The internal structure and operating principle of this solid-liquid separator are as follows. Liquids and solids (such as solid particles) flow tangentially from the inlet 18 into the upper chamber 24 and are swirled. The liquid and the solid matter are accelerated by passing through a slit-shaped special rotation mechanism 26 provided in a tangential direction, and flow vigorously into the separation cylinder 12. The solid matter heavier than the liquid hits the inner wall of the separation tube 12 due to centrifugal force, and separation of the solid matter and the liquid (primary separation) starts. The solids slowly settle down along the inner wall of the separation tube 12 and accumulate in the lower chamber 28. The liquid that has descended as a rotating vortex is instantaneously rapidly decelerated by the lower guide blade mechanism 30, the velocity energy is changed to pressure energy, and solid-liquid separation (secondary separation) is performed. The liquid containing no solid matter rises sharply by the central vortex (negative pressure zone), passes through the outflow pipe 20, and flows out of the outlet 21 to the outside. The solid matter deposited in the lower chamber 28 is discharged from the solid matter discharge port 22 periodically or continuously as necessary.

A pump for feeding solids is installed on the inflow side of the solid-liquid separator. That is, a configuration is adopted in which the discharge side of the pump and the inflow side of the solid-liquid separator are connected by piping. The stock solution (liquid containing solids) passes through a pump, is pressurized by the pump, sent to a solid-liquid separator, where it is cleaned.

し、ポンプの保護を図ることが考えられる。When the pump is installed on the inflow side of the solid-liquid separator, the pump has a disadvantage that the liquid to be separated and the solid matter pass through, so that the pump is liable to be worn and its life is shortened. Since the solid-liquid separator as described above separates solids using centrifugal force generated by rotation of the liquid passing therethrough, whether the passage of the liquid is due to the pushing force from the inlet, Irrespective of the suction force at the outlet, as long as a certain amount of liquid passes, a centrifugal force is generated and the performance is exhibited. Therefore, it is conceivable that the solid-liquid separator is intentionally installed on the suction side of the pump so that only the clean liquid from which the solid matter is separated is sucked, and the pump is protected.

再開時の分離性能の低下も避けられない。However, in the case of a solid-liquid separator utilizing centrifugal force, if the solid-liquid separator is simply installed on the suction side of the pump, when the solids discharge port is opened during operation, the solid-liquid separator is opened. Inhalation of air causes turbulence in the vortex inside the solid-liquid separator. Therefore, there arises a problem that the original performance of the solid-liquid separator cannot be exhibited. In order to solve this problem, the solid-liquid separation operation must be temporarily interrupted at the time of discharging solids. However, this will not only reduce the operation efficiency but also inevitably reduce the separation performance when the operation is restarted.
