Description

[Detailed description of the invention] Engraving (no changes to the content) The present invention relates to an apparatus for separating predominantly liquid mixtures containing solid particles. More particularly, it relates to a centrifugal liquid purifier.

Background of the invention An important part of processes related to cleaning liquids for mechanical impurities. As a first step, the interior of the purifier where mechanical impurities tend to settle, especially its circulation. There is removal of sludge from the trochanter.

Continuous removal of sludge from rotor interior by automated system without rotor stoppage A rotor rotates with a centrifugal purifier providing discharge or periodic sludge removal. Centrifugal liquid purifiers are widely used in which the sludge buildup is discharged only when the product is stopped. It is used. Such centrifugal liquid purifiers are characterized by their simplicity of construction, reliability and relative Its feature is low cost.

However, minute cleaning of liquids requires sealing inside the rotor; In order to make the device work more efficiently, the inside of the rotor carries the liquid stream being cleaned. A separating partition is housed therein, which constitutes a slotted passageway for the separation. these Various structures can be considered as partition walls. For example, tapered It may be in the form of a stack of plates or coaxial cylindrical shells. of this type Centrifugal purifiers micro-clean liquids for solids smaller than 1# in diameter.

During the operation of a centrifugal purifier, sludge accumulates and begins to affect the quality of cleaning. It is only after this time that it is ejected from the inside of the rotor. The sludge removal process is often This requires partial disassembly of the centrifugal purifier, which in turn requires special equipment and tools. use is required and results in fluid waste and idling during cleaning. will be done. In many cases, the costs associated with sludge discharge can be so high as to make the use of such purifiers uneconomical.

Centrifugal liquid purifiers are known that include a hollow rotor that can rotate around a vertical hollow shaft. (see SU, A 640.477). rotor sealed housing has a slotted passage in its central part for conveying the liquid to be cleaned. These passages communicate with the interior of the upper and lower parts of the rotor. It's working. These interiors house the blades for rotating the liquid stream and The blade is connected to the housing and the separating bulkhead for rotation together. Applicable The purifier is further fed with the liquid to be cleaned, which is in communication with the interior of the lower part of the rotor. A pipe for clean liquid communicating through the upper interior of the rotor and the hollow shaft. A pipe for discharging the body, as well as for collecting the sludge accumulated inside the rotor. It also includes a container to hold the water.

The hollow shaft is in the form of two coaxial pipes. One end of the inner pipe is communicates with the upper interior of the rotor, while the other end is for discharging clean liquid. It passes through the pipe.

The pipe for delivering the liquid to be cleaned is coaxial between the inner and outer pipes. rotation through the air gap and holes made in the outer buzz on the lower interior of the rotor. It communicates with the lower part of the child.

The lower interior of the rotor is cylindrical, confined on one side by the flat bottom of the rotor. There is. Separation bulkheads are constructed in such a way that the spacing between the windings acts as a passageway for transporting the liquid. It is made as a flat belt that is spirally wrapped around the belt. The blades located inside the top and bottom of the rotor as well as the bottom connected to form an integrated unit.

During cleaning, sludge tends to accumulate inside the separating bulkhead and the lower part of the rotor. vinegar As ludge builds up, the rotor is stopped, fluid is released, and the housing is removed from the bottom. Separate the top part of the ring and then assemble the integrated unit including the belt, blade and bottom. The rotor must be disassembled by removing the parts.

The inside surface of the cup should be scraped with a scraper or similar material on top of the sludge collection container. The sludge is cleaned mechanically, but the integrated unit cleaning solution. The sludge collection container is not connected to the rotor.

After sludge cleaning the rotor elements, the purifier is reassembled and the liquid to be cleaned is charged and the cleaning process is repeated.

Judging from the above explanation, removing sludge from the inside of a centrifugal purifier is labor-intensive. On the other hand, the time required to remove the sludge from the inside of the rotor is 1 It's more than an hour.

This can lead to liquid loss, contamination of the work area, etc.

Disclosure of invention The present invention utilizes a rotor to reduce the time and effort involved in the sludge removal process. Shaped to allow removal of sludge from the interior of the rotor without separating the The inside of the lower part of the rotor is shaped and the sludge collection container is shaped in relation to the rotor. The purpose is to provide a centrifugal liquid purifier that is positioned as such.

The object of the invention is to provide a hollow rotating shaft capable of rotating around a vertical hollow shaft. a pipe for communicating with the lower interior of the rotor and conveying a stream of liquid to be cleaned; and communicates with the upper interior of the rotor through the hollow shaft and the tilt that accumulates within the rotor. pipe for discharging clean liquid, including a container for collecting sludge with and a pressure-sealed housing of the rotor is separated in its central portion. and a bulkhead communicating with the upper and lower interiors of the rotor on different sides thereof. constitutes a slotted passageway for conveying the liquid flow during cleaning; , a liquid flow diversion connected to the housing and separating bulkhead for simultaneous rotation. In a centrifugal liquid purifier in which blades of , the container for collecting sludge is sealed and positioned under the rotor, and cleaned The inside of the lower part of the rotor is in communication with a vibrator for sending the liquid flow to be It has a conical shape, and the small bottom of the cone is connected to a sealed container for collecting sludge. - Achieved by communicating with the container through this internal small base. be done.

Preferably, the hollow shaft is fixed in a sealed container for collecting sludge. has been done.

This configuration of the centrifugal liquid purifier prevents the rotor from disassembling. The time and labor costs for draining sludge from the inside of a 7il - significantly reduced be able to.

Sludge may be removed from the interior of the rotor in any manner. For example, rotation When the child stops, the loosely adhered sludge is deposited on the vertical walls of the housing and the separation barrier. It slides down from the wall to the bottom of the rotor and from there along its tapered surface. and slide to the sludge collection container.

To accelerate the sliding of the sludge, for example by applying vibrations to the rotor or It is possible to use a foaming effect, thus removing sludge from the rotary stop The time spent on this can be reduced to 5 minutes.
