BACKGROUND OF THE INVENTION
The present invention relates to a separator, and more particularly to a separator having a simple structure that efficiently separates impurities such as dust and oil mist from a gas.
[0002]
[Prior art and problems]
In recent years, at work sites that handle NC lathes, general-purpose lathes, etc., health hazards to workers due to suction of oil smoke, oil mist, etc. generated from the NC lathe, etc. It has become a problem.
[0003]
Such oil smoke and oil mist also contain dust such as metal powder, and as a device that separates these impurities from the gas to make it a clean gas, a louver that uses inertial force due to a sudden change in the flow direction is conventionally used. Inertial dust collectors such as dust collectors, centrifugal dust collectors such as cyclones that use centrifugal force generated by rotational motion, and filter dust collectors that use filter media such as woven cloth, filter paper, and fiber packed beds Is used.
[0004]
Here, a filter dust collector using a filter such as a woven fabric is a device that can efficiently separate (collect dust) impurities contained in the gas, but it is essential to periodically clean or replace the filter. There was a big problem in terms of maintenance.
Inertial dust collectors that use inertial force due to sudden changes in the flow direction are relatively simple in structure, many compact, and easy to maintain such as cleaning, but once separated metal powder, etc. The re-scattering phenomenon in which the impurities are again carried away by the air flow is likely to occur, and there is a problem in terms of separation (dust collection) efficiency.
Furthermore, in centrifugal dust collectors that use centrifugal force generated by rotational movement, the separation (dust collection) efficiency is higher than that of the above inertial dust collectors, and there are many things that are easy to maintain. The apparatus generally has a problem of increasing in size.
[0005]
The present invention has been made in view of various problems of the above-described apparatus for separating impurities such as dust and oil mist from the gas, and the object thereof is simple and compact. In addition, an object of the present invention is to provide a separation device having the advantage of an inertia dust collector that maintenance such as cleaning is easy, and having a higher separation (dust collection) efficiency than the inertia dust collector.
[0006]
[Means for Solving the Problems]
As a result of repeated testing and research to achieve the above-described object, the present inventors can rotate the flow inside the baffle plate when the flow of the airflow is suddenly changed by the baffle plate like an inertia dust collector. If possible, impurities can be separated from the gas not only by inertial force but also by centrifugal force, and the impurities separated from the gas can be pressed against the wall surface of the baffle plate by the action of centrifugal force, thus preventing separation (dust collection). ) Obtained knowledge that efficiency was dramatically improved, and completed the present invention.
[0007]
That is, according to the present invention, the wall body is provided with a substantially X-shaped cross section, and the side wall surface defined by the adjacent wall bodies is formed into a curved surface to form a baffle plate member. A plurality of baffle plate members are arranged in a staggered manner so that the wall body enters the side wall surface of the adjacent baffle plate member with an appropriate interval, and impurities such as dust and mist are formed on the baffle plate. A separation apparatus that separates and removes impurities from the gas by passing a gas containing the gas.
[0008]
According to the separation device according to the present invention described above, the baffle plate has the special shape described above. Therefore, a rotational force can be applied to the gas passing through the baffle plate, and an impurity utilizing centrifugal force such as a cyclone. Therefore, a separation device with high separation (dust collection) efficiency can be obtained.
In addition, structurally, it becomes a structure like an inertia dust collector that installs a baffle plate in the gas flow, so the advantage of the inertia dust collector, that is, the structure is simple, compact, cleaning, etc. Thus, the separation apparatus has the advantage that it is easy to maintain.
[0009]
Here, in the present invention, in order to obtain a baffle plate capable of giving a rotational force to the gas passing therethrough, a cylindrical protrusion is formed on the top end portion of each wall body of the baffle plate member constituting the baffle plate. Is preferably formed.
Further, if a groove extending in the longitudinal direction is formed on the side wall surface of the baffle plate member, the groove supplements impurities in the gas pressed against the side wall surface of the baffle plate member by centrifugal force, and is below. In order to achieve the guiding effect, it is preferable because the device can prevent re-scattering of more separated impurities.
Further, the two baffle pieces erected on every other baffle plate member are inserted between the baffle plate members erected on the other frame piece. It is preferable that the baffle plate is combined in a state in which the baffle plate is formed because the baffle plate is easy to manufacture and maintenance such as cleaning is easy.
Further, it is preferable to arrange the baffle plates in a plurality of rows in the gas flow direction because a separation device with better separation (dust collection) efficiency can be obtained.
