Abstract

PURPOSE:To almost perfectly separate and discharge impurities in flowing water by the primary and secondary separating actions of a solid substance, by combining a large number of small multi-cyclones each consisting of a vertical vortex flow plate and a perforated cylindrical pipe in a liquid cyclone. CONSTITUTION:Primary separation is performed by a method wherein revolving motion is imparted to water containing impurities flowing-in from a inflow port 5 mounted to the upper end of a main body cylindrical pipe 2 from the tangential direction and said water is revolved and fallen through an inverted cone shaped pipe 3 while solid particles with high specific gravity are gathered to the peripheral wall of said pipe 3 and sedimented therealong. Particles with low specific gravity revolves and rises to reach a box shaped multi-cyclone constituted of vertical vortex flow plates 10 where particles with relatively high specific gravity are sedimented and light particles float promortionally. A perforated cylindrical pipe 8 has filtering action and only clarified water flows in said pipe 8 from the perforations 9 thereof and is sucked in the suction port 6 of a flooding pipe 7 to flow out to the direction of a pump from an outlet.

Description

[Detailed Description of the Invention] "Industrial Field of Application" This invention is applicable to cases where a liquid water pipe is laid above the ground or in a middle or high part of a mountain top where it is unavoidable due to the structure. This invention relates to a new type of liquid multi-cyclone device installed at the f-end for the purpose of drawing air out of the liquid and also removing sand, dust, etc. contained in the liquid.

"Prior Art" Generally, a hydrocyclone presses suspended water containing solid particles such as earth and sand from an inlet into a main body circle from a tangential direction to cause a swirling motion, and air is taken out from the liquid. At the same time, the above-mentioned solid particles are collected on the peripheral wall by centrifugal force, rotated down the outer periphery, separated by sedimentation in the lower stage tank, and discharged.Meanwhile, an overflow pipe was installed in the center of the main cylindrical tube to overflow clear water with air. Something with a structure that allowed it to flow was being used.

However, when using river water, etc., in addition to sand with a large specific gravity,
If miscellaneous floating objects are mixed in, such as floating objects with small specific gravity or objects that gather at the center due to water resistance due to their shape, the simple cyclone km described above will be able to deal with the problem. The public treasury was in an impossible situation.

``Means for Solving the Problems'' Therefore, this invention is a new hydrocyclone device for solving the above problems, in which water containing not only solid particles but also miscellaneous floating contaminants is introduced from the tangential direction of the main cylindrical tube. is sucked up by a pump or connected to a discharge pipe, and swirling motion is caused by the flow velocity, whereby solid particles with a large specific gravity are not collected on the peripheral wall by centrifugal force, but are caused to undergo primary swirling, descent, and sedimentation separation. Furthermore, a hot water pipe is installed vertically in the center of the main cylindrical pipe of the hydrocyclone, and a cylindrical pipe with a hole for water sampling of approximately the same length as the main cylindrical pipe is installed concentrically around the outer periphery of this spout. A large number of vertical vortex roots are installed radially from the center, forming a large number of box shapes.

The vertical vortex plates have a large number of box-shaped boxes that are open on the outside, and upward vortices are always generated in the opposite direction to the main flow.

A small eddy current is generated inside each box-shaped box, in which objects with a large specific gravity settle, and objects with a small specific gravity and solid objects with a shape that creates water resistance are promoted to float. Therefore, the above-mentioned perforated cylindrical tube acts as a filter to allow secondary separation of miscellaneous solids by this device, and this perforated cylindrical tube has a sufficient opening If! i product, flowing water flows into the interior through the opening, and only clear water flows out from the mouth of the overflow pipe. As described above, the present invention is a new liquid multi-cyclone device that uses this new mechanism to almost completely separate and discharge impurities in flowing water through the primary and secondary solid separation actions. .

``Embodiment'' An embodiment of the present invention will be described below based on the drawings. A cyclone main body (■) is provided in which the lower half of a vertical cylindrical tube (2) is formed into an inverted conical tube (3), and the upper part of the main body (■) is The container (4) is a closed type or an open type without a lid, and a liquid inlet (5) is attached to the upper end of the tube wall in the tangential direction of the cylindrical tube (2).
The central number of the cylindrical tube (2) of the main body is set at an appropriate height with the spout (6
An overflow pipe (7) having an overflow pipe (7) is installed vertically, and its lower end penetrates the outer wall of the inverted conical pipe (3) at the bottom of the main body.
7) is surrounded by a perforated cylindrical tube (8) having a large number of holes (9) in the peripheral wall, and this perforated cylindrical tube (8)
There are 12 vertical vortex plates (10
is stretched, and a drain pipe αD and a drain port @ are provided at the tip of an inverted conical tube (3) at the lower end of the main body.

Note that FIGS. 5 and 6 are examples of an open type without a lid, and u indicates a spillage outlet.

"Function" The liquid multi-cyclone device of the present invention configured as described above first collects sand and miscellaneous foreign matter flowing in from the inlet (5) attached to the upper end of the main cylindrical tube (2) in the tangential direction. A swirling motion (arrow a) is applied to the water contained in the water due to the flow velocity, and this centrifugal force collects solid particles such as sand with a large specific gravity on the surrounding wall, causing them to swirl, descend, and settle into the inverted conical tube (3) at the bottom. Perform two primary separations.

These concentrated sand grains are discharged to the outside by opening the discharge port (6) 2 at the lower end from time to time.

In addition, fine sand with low specific gravity and floating dust, etc., swirl and float together with water and rise, forming a large number of box-shaped multi-cyclones composed of vertical vortex plates αQ. A small upward eddy current (arrow b) is generated in the direction, in which objects with relatively high specific gravity settle, and objects with low specific gravity and solid objects with a shape that creates water resistance are promoted to float due to the vortex flow.

Therefore, the solids are subjected to a second separation by a device consisting of a vortex plate and a perforated cylindrical tube (8), and the perforated cylindrical tube (3) acts as a filter, allowing only clear water to pass through the perforated cylindrical tube (9). It flows into the interior, is sucked into the spout (6) of the overflow pipe (7), and becomes the overflow pipe (7).
) flows out toward the pump from the outlet.

"Effects of the Invention" As described above, the present invention has a small double cyclone device in which a large number of small multi-cyclones each consisting of a vortex plate and a perforated cylindrical tube are combined inside a single hydrocyclone. The centrifugal force, rising eddy current, and G allow almost complete removal and separation of earth and sand and floating contaminants such as U dust in the flowing water, and only clear water can be sent through the overflow pipe, and is limited to closed type systems. This is a new type of liquid multi-cyclone device that can be used as a sink with an open top depending on the application.
