Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a separator for separating a mixture of a solid phase and a liquid phase, that is, a solid-liquid mixture into a solid phase and a liquid phase.

Conventional solid-liquid separators, such as filters, wet cyclones, and centrifugal separators, are all used as separators that take advantage of their characteristics, but it is particularly difficult to separate high viscosity solids and liquids.

In order to solve this problem, the present invention provides a novel solid-liquid separator, which has a mechanism and structure that can be used even under high temperature and high pressure, and is particularly suitable for separating solid-liquid mixtures that have low viscosity at high temperatures. It is something.

That is, the present invention has a hollow shaft attached to the upper and lower center of a cylindrical container, and the hollow shaft passes through a filtration chamber consisting of a conical chamber whose top surface is an umbrella-shaped plate and whose bottom surface is a filtration plate. The filtration chamber is fixed to the hollow shaft as shown in FIG.
This solid-liquid separator is characterized in that a filtrate is discharged through a hollow shaft, and a drive device connected to the hollow shaft provides quick return motion to the filtration chamber through the hollow shaft.

The accompanying drawings show an embodiment of the solid-liquid separator of the present invention.

FIG. 1 is a longitudinal sectional view of the solid-liquid separator, FIGS. 2 and 3 are a longitudinal sectional view and a bottom view of the filtration chamber, respectively, and FIG. 4 is a plan view of the drive device.

To explain the solid-liquid separator of the present invention according to the attached drawings, a container 1 has a cylindrical sealed structure with a conical bottom, and inside the container is a hollow shaft 2 attached to the center of the container and a filtration chamber 3.
It is composed of.

The filtration chamber 3 has an umbrella-shaped plate 4 on the top and a filtration surface 5 on the bottom.
It is a conical chamber, and is fixed to a hollow shaft 2 that passes through the center of this filtration chamber 3.

A hole 6 through which the filtrate flows is provided in the portion of the hollow shaft 2 to which the filtration chamber 3 is attached.

The hollow shaft 2 is connected to a drive device 7 such as an air cylinder or an electric type provided at the top of the container, and the drive device 7 provides a quick return motion to the filtration chamber 3 via the hollow shaft 2.

The solid-liquid mixture flowing into the container 1 is filtered by the filtration surface 5,
The filtrate enters the hollow shaft 2 from inside the filtration chamber 3 and flows out from the hollow shaft.

On the other hand, the solid phase is divided into two types: one that settles inside the container and settles on the bottom of the container, and the other that adheres to the filtration surface 5 or is deposited on the umbrella-shaped plate 4.

The latter is detached or shaken off by the quick return movement and falls to the bottom of the vessel.

The solid-liquid mixture enters the container 1 through the intake port 8, and the liquid phase portion passes through the filtration surface 5 of the filtration chamber 3, passes from the interior of the filtration chamber 3 through the pore 6, through the hollow shaft, and passes through the rotary joint 9 to the outlet. It is discharged from 10.

Some solid phase parts settle directly to the bottom of the container 1, while others adhere to the filtration surface 5 of the filtration chamber 3 or accumulate on the umbrella-shaped plate 4. The solid phase deposited on the umbrella plate 4 is transferred to the drive device 7.
The solid phase is separated or shaken off by the quick return movement of the solid phase, and is deposited at the bottom of the vessel along with the solid phase that settles directly.

The precipitated solid phase is extracted by an automatic valve 11.

The solid-liquid separation liquid of the present invention can easily separate a highly viscous solid-liquid mixture whose viscosity decreases at high temperatures if the container has a heat-resistant and pressure-resistant structure.

Further, by installing the filtration chambers 3 in several stages as shown in FIG. 1, the filtration area can be increased.

Furthermore, by introducing the solid-liquid mixture from the cutting line direction of the cylindrical container 1, a cyclone effect can also be exerted.

The separator according to the present invention has a simple structure and mechanism, is easy to operate continuously, and has excellent separation effect and filtration ability.

In addition, the production cost is relatively low, making it highly economical.

In particular, the solid-liquid separator of the present invention can exhibit remarkable effects when used for separating solid-liquid mixtures that have low viscosity at high temperatures, such as solid-liquid separation in the liquefaction process of quartz.
