Description

  TECHNICAL FIELD The present invention relates to an oil mist dust collector, and more particularly, multiple stages executed in different ways so that oil and air contained in oil mist generated at various industrial sites can be separated and discharged more efficiently. The present invention relates to an oil mist dust collector that can induce clean air discharge due to the separation process.

  This application claims priority based on Korean Patent Application No. 10-2015-0101271 filed on July 16, 2015, and all the contents disclosed in the specification and drawings of the corresponding application are incorporated herein by reference. Is done.

  Generally, an oil mist collector is configured to suck in air containing a large amount of oil particles generated at various industrial sites and canteens, that is, oil mist, separate the oil and air, and discharge them separately. Device. At this time, the discharged oil can be collected and recovered separately and reused, and the working environment can be maintained exhilaratingly by purified air. Oil mist dust collectors are used in industrial fields.

  Conventional oil mist dust collectors can be broadly classified into filter filtration methods, centrifugal separation methods, and electrostatic force separation methods. A filter filtration type dust collector is the most common form of dust collector configuration. A blower fan and a filtration filter are installed inside the main body to suck oil mist, and the filter filters out impervious oil particles for purification. Configured to exhaust only the generated air. However, there is a problem that it is uneconomical in terms of maintenance cost because the filter must be frequently replaced in order to exhibit high filtration efficiency.

  A centrifugal dust collector is configured to form a rotating airflow using a centrifugal separator and to separate oil and air using centrifugal force. Since the form and configuration of the centrifugal separator can be differentiated in various ways depending on the nature of the separation object, it is necessary to develop the most suitable and efficient configuration. On the other hand, the centrifugal separation method can reduce the maintenance cost as compared with the filter filtration method, but has a problem that the fine particles cannot be separated because the filtration efficiency is lowered.

  In addition, electrostatic force separation type dust collectors are configured to separate oil particles after charging oil mist and agglomerating oil particles, so they are generally completed when used together with the filter filtration method and the centrifugal separation method. This is possible.

  On the other hand, the Japanese Utility Model Publication No. 20-0418713 has become known since the above problem has been recognized, but this is a form of a dust collector in which both the centrifugal separation method and the filter filtration method are configured. .

  Briefly described in connection with this, in constructing the inside of the main body, a blower fan is installed at the upper part and the lower part, the oil mist is centrifuged at the lower part, and filtered through the filter at the upper part, and then purified. It is configured so that air is discharged.

  In this way, the filtration efficiency was increased by the combination of two different separation methods, but due to the structural limitations of the internal components, a smooth flow of airflow was not formed between the lower part and the upper part, There is a problem that installation of one or more blower fans is inevitable.

  In addition, since the motor that drives the blower fan is directly exposed on the air flow path, it also includes the problem that the life of the device can be shortened due to adsorbed dust etc., which has been improved more efficiently. Development of a dust collector consisting of components is urgent.

  The present invention has been made to more actively solve the above-mentioned various problems, and induces the discharge of clean air due to multi-stage separation processes performed in different ways. This is the solution issue.

In order to achieve the above-mentioned solution, in configuring the oil mist dust collector 100 of the present invention,
The oil mist dust collector 100 has a pull-in cover 10 provided with a through-hole penetrating from the inside, and a bundling cover 10 provided in the center so as to provide a path for oil mist in the atmosphere so as to provide an entry path. A separation guide housing 30 for guiding the fixed position of the foam filter 20 and the alignment of the impeller 40 and guiding the oil mist in a vaporized state to be converted into a liquefied state by sequentially performing collision separation and centrifugal separation; A body 60 that is intimately arranged at the rear end of the separation guide housing and provides a hollow inner space that is blocked from the outside so that the spiral rotation of the oil mist proceeds; and the impeller is fixedly coupled to the inner space of the body; The impeller flows from the retraction cover by acting as a power source that can be induced to rotate in one direction. Drive motor 70 for performing oil mist filtration, HEPA filter 81 for re-filtering oil mist while being accommodated in the inner space of the rear end of the body, and the rear end of the body being opened is sealed from the outside A collecting part 80 formed by dividing into a cover body 82 including a discharge port 83 so as to provide a discharge path for filtered clean air, and oil sludge generated from the separation induction housing located at the bottom of the body And a water collecting tank 90 for collecting oil sludge generated from the body via a guide pipe 91.

  Here, the separation guide housing 30 maintains the same separation gap from the outer edge portion of the impeller 40 while being formed so as to extend compared to the diameter of the rod 31 and the rod 31 that is extended at the tip for the interposition of the foam filter 20. In this way, the oil mist sucked through the pull-in cover 10 is separated by collision with the foam filter 20 and the centrifugal force acting on the oil mist when the impeller 40 rotates. It is characterized in that the centrifugal separation process in which oil sludge is intensively induced in the annular protrusion 32 due to the above can be performed in parallel.

  The annular protrusion 32 is configured to have a polygonal cross section including a circle, a triangle, and a square.

  On the other hand, a coil turning guidance unit 50 is further interposed in the space between the impeller 40 and the drive motor 70, and the impeller is rotated by the same rotation of the impeller and the coil turning guidance unit through the power source of the drive motor. The coil swirling induction unit 50 includes several components in which the flow of the oil mist that has been subjected to the centrifugal separation is induced by the impeller 40, including filtering the oil mist that could not be liquefied by the induced centrifugation in the internal space of the body. The piercing portion 51 is alternately arranged between the respective penetrating portions, and is formed so as to be close to the inner diameter of the body 60, while generating a vortex phenomenon due to a reduction in the traveling speed of the oil mist and the oil to the penetrating portion. Several extensions 52 that guide the mist's concentrated path of travel and flow through the penetration Characterized in that it is configured to include a few of the guide vanes 53 which are protruded in the driving motor 70 direction on the boundary between the penetrating part and the extended part so as to be able induce a spiral rotation in the oil mist has.

  Here, the guide blades 53 have a shape that is bent in a round shape in the center direction of the body 60, and the protruding range in the direction of the drive motor 70 is configured to be the same as the width of the through portion 51. It is characterized by that.

  According to the present invention having the above-described configuration, the discharge of clean air can be more efficiently induced due to the multi-stage separation process performed in different manners. By carrying out the centrifugal separation methods that are not identical to each other while sequentially performing the tertiary centrifugal separation, there is an effect that the filtration efficiency from the oil mist and the oil recovery rate are further maximized.

However, the present invention is not limited to the embodiments disclosed below, and can be embodied in various different forms. However, this embodiment is provided in order to complete the disclosure of the present invention and to fully inform the person of ordinary skill in the technical field to which the present invention pertains the scope of the invention. It is only defined by the category of the term. The same reference numerals denote the same components throughout the specification.

  In the present invention, oil mist that is smogized while being mixed with the atmosphere due to oil evaporation caused by frictional heat generated during processing of a target object at an industrial site and scattering of oil induced by tool rotation is executed. Disclosed with respect to a dust collector 100.

  FIG. 1 is a perspective view of an oil mist dust collector constructed according to a preferred embodiment of the present invention, FIG. 2 is a conceptual diagram schematically showing a part of the internal configuration of FIG. 1, and FIG. 4 is an exploded perspective view of an essential part of an oil mist dust collector configured according to the preferred embodiment of the present invention, and FIG. 4 is a cross-sectional view showing in detail a flow process of the oil mist sucked by the present invention.

  As shown in FIGS. 1 to 4, the oil mist dust collector 100 presented as a feature of the present invention can more efficiently separate and discharge oil and air contained in oil mist generated at various industrial sites. The main part is to induce clean air discharge due to a multi-stage separation process performed in different ways.

  For this purpose, the oil mist dust collector 100 has a pull-in cover 10 provided with a through-hole penetrating from the inside and protruding through the center so as to provide an entry path for oil mist in the atmosphere, and corresponds to the pull-in cover. Separation guidance that induces the oil mist in a vaporized state to be converted to a liquefied state by inducing the fixed position of the foam filter 20 and the alignment of the impeller 40 and sequentially performing the collision separation and the centrifugal separation. The housing 30 is closely arranged at the rear end of the separation guide housing, and the body 60 provides a hollow inner space that is shut off from the outside so that the spiral rotation of the oil mist proceeds. The impeller is fixed to the inner space of the body. By acting as a power source that can be coupled and the unidirectional rotation of the impeller can be induced, A drive motor 70 that performs filtration of the oil mist that flows in, a filter member 81 that performs filtration of the oil mist again while being accommodated in the internal space of the rear end of the body, and the rear end of the body that is opened are sealed from the outside. While being collected in a cover body 82 including a discharge port 83 so as to provide a discharge path for filtered clean air, the oil generated from the separation guide housing is located at the bottom of the body. An oil sludge generated from the sludge and the body is constituted by a water collecting tank 90 that collects the oil sludge through a guide pipe 91.

  The pull-in cover 10 is a component into which oil mist flows first, and does not have an identification number, but forms a through-hole having a shape protruding forward, which is the same as that in the drawing, so that more intensive suction efficiency is achieved. Can be realized.

  The pull-in cover 10 covers the entire surface of the separation guide housing 30 with the foam filter 20 interposed therebetween. These mutual couplings can be performed by various known fastening methods including a toggle clamp (not shown). It is a trivial fact that can be done by means.

  The foam filter 20 is a component provided to provide resistance to the oil mist flowing through the pull-in cover and perform collision separation, and is preferably fixedly attached to the tip of the rod of the separation guide housing.

  Here, the foam filter 20 is a kind of diesel particulate filter, and is a ceramic particulate filter that is used as a filter, and has an advantageous effect for preventing fine sludge from permeating.

  The impeller 40 is a general element for guiding the centrifugal separation to be performed by transmitting an artificial centrifugal force to the oil mist while rotating due to the rotational force of the drive motor 70.

  For this purpose, the impeller 40 of the present invention is installed on the space of the annular protrusion 32 of the separation guide housing 30 in a state of being fixed on the central axis of the drive motor, thereby rotating the impeller. The induced centrifugal force can be concentrated on the inner wall of the ring-shaped protrusion located at a distance from the centrifugal force, thereby inducing the vaporized oil mist to be converted into a liquefied state.

  Such an impeller is a known one, and in the present invention, the fixing position of the impeller is specified, and thereby, the core is to maximize the dust collection efficiency. This will be described in detail in conjunction with the following drawings.

  As described above, the collection unit 80 can be configured to be divided into the filter member 81, the cover body 82, and the discharge port 83, and improves the sealing force by covering the entire rear end of the body 60. .

  At this time, as the filter member 81, a Saran filter including a HEPA filter, a demister filter, or the like can be employed.

  For example, a HEPA filter (High Efficiency Particulate Air Filter) is adopted such that the oil mist that has been subjected to the collision separation by the foam filter 20 and the centrifugal separation by the impeller 40 and the coil turning guide unit 50 is subjected to the filtering action again. Particles having a size of 3 μm can be collected up to 99.997%, and a highly efficient filtration function can be exhibited.

  As shown in FIG. 3, the separation guide housing 30 presented as the main part in the present invention has a rod 31 extended at the tip for the interposition of the foam filter 20 and an expansion compared to the diameter of the rod. However, the outer peripheral portion of the impeller 40 is divided into an annular protrusion 32 for covering in a state where the same separation gap is maintained.

  With such a configuration, oil sludge to the annular protrusion 32 is concentrated due to collision separation of the oil mist sucked through the pull-in cover 10 by the foam filter 20 and centrifugal force acting on the oil mist when the impeller 40 rotates. In parallel with the centrifugation process induced by

  That is, the oil mist that has passed through the foam filter 20 as shown in FIG. 4 comes into contact with the impeller 40 that continues to rotate in one direction, and is concentrated on the inner wall of the annular protrusion 32 by the centrifugal force induced by the rotational force. However, at this time, the oil particles are collected in the ring-shaped protrusions while being separated from the air, and flow into the water collecting tank 90.

  The annular protrusion 32 may be provided in various shapes according to the amount of oil to be collected or depending on the installation location, as illustrated in FIG.

  FIG. 5 is an exemplary cross-sectional view showing that the configuration of the ring-shaped protrusion that is the main part of the present invention can be applied in various ways. As shown in FIG. The intended purpose can be achieved by having a polygonal cross section including a circle, a triangle, and a square.

  The water collection tank 90 is arranged at the bottom of the separation guide housing 30 and the body 60 and collects oil particles guided from the foam filter 20, the impeller 40, the coil turning guide unit 50 described later, and the filter member 81, respectively. To do.

  For example, the oil particles collected by the separation guide housing 30 and the impeller 40 fall toward the water collection tank 90 while concentrating on the region drilled at the bottom of the ring-shaped protrusion 32, and are located inside the body 60. The oil particles collected via the swivel guidance unit 50 and the filter member 81 are collected through the water collection tank 90 by using a predetermined guide pipe 91 to collect the corresponding oil. For this reason, a through hole must be drilled in the bottom of the body so that the guide pipe can be pulled in, and an appropriate space that can accommodate the guide pipe is also drilled on one side of the water collection tank. It must be.

  Reference numeral 84 denotes an exhaust duct, which has a shape bent upward so as to guide smooth discharge of clean air while being meshed with and connected to the discharge port 83 of the collection unit 80. Obviously, various other shapes are possible.

  Meanwhile, the present invention is characterized in that a coil turning induction unit 50 is further interposed in a space between the impeller 40 and the drive motor 70.

  With such a configuration, the oil mist that could not be liquefied by the centrifugal separation performed from the impeller is guided by performing the same rotation of the impeller and the coil turning guiding unit 50 through the power source of the drive motor 70. Filter again in the internal space of the body 60.

  For this purpose, the coil turning guiding unit 50 is arranged alternately between several through portions 51 through which the flow of oil mist that has been subjected to centrifugal separation by the impeller 40 is guided, and between the respective through portions. The eddy current phenomenon caused by the reduction in the traveling speed of the oil mist is generated while extending so as to be close to the mist, and several extending portions 52 for inducing a concentrated traveling path of the oil mist with respect to the penetrating portion, and from the penetrating portion It includes several guide vanes 53 that protrude in the direction of the drive motor 70 on the boundary line between the penetrating part and the extension part so as to guide the helical rotation to the oil mist that has been introduced.

  As shown in the drawing, the penetrating part 51 is divided into a total of three parts and knitted. By providing a movement path for the oil mist sucked through the impeller 40, the oil mist is placed in the space of the body 60. It becomes a means to move.

  Further, the extension portion 52 is divided and knitted so as to correspond to such a penetration portion, thereby blocking the oil mist progression path and simultaneously concentrating the oil mist progression path in the penetration region. Is done. At this time, while the flow of the oil mist is suppressed by the extension portion, a vortex flow is naturally generated in the corresponding region, so that the oil mist stays in the space between the impeller and the coil turning guide unit 50 for a moment. This leads to the result of extending the centrifugation execution time, and the filtration efficiency can be further increased. In particular, by applying artificial rotational force to the oil mist that moves inside the body depending on the through-hole 51 (which is possible by rotating the coil turning induction unit), the spiral on the target body Shaped centrifugation can be induced.

  That is, the penetrating part 51 and the extension part 52 become a means for adjusting the oil mist that has passed through the impeller indiscriminately and excessively so as not to go directly into the body, and at the same time, against the oil mist that is structurally concentrated on the penetrating part. It can be used as a means to actively guide spiral turning. Therefore, in the present invention, a predetermined guide blade 53 is further provided on the boundary line between the penetrating portion and the extending portion.

  The guide vanes 53 have a shape that is bent in a round shape in the center direction of the body 60, and the protruding range in the direction of the drive motor 70 is configured to be the same as the width of the penetrating portion 51. preferable.

  In other words, due to the characteristics of the coil turning guidance unit 50 that rotates itself with the rotational force of the drive motor 70, it is bent so that a stronger spiral rotation is induced against the oil mist that moves through the through portion 51. A guide vane 53 having a shape is further provided, and at this time, the protruding length of the guide vane should not be excessively large or small than necessary.

  For example, after a single disk is provided to form the coil turning guidance unit 50, the generation of the penetrating part and the extension part is induced by incising the edge surface evenly with a certain gap, and the incision is made. The surface can be swung to one side and can be erected to induce the generation of guide vanes presented in the present invention.

  According to the present invention having the above-described configuration, the discharge of clean air can be more efficiently induced due to the multi-stage separation process performed in different manners. By carrying out the centrifugal separation methods that are not identical to each other while sequentially performing the tertiary centrifugal separation, there is an effect that the filtration efficiency from the oil mist and the oil recovery rate are further maximized.

  Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely illustrative and various modifications and equivalents will occur to those skilled in the art. It should be clarified that this embodiment is possible. Therefore, the true technical protection scope of the present invention should be construed by the appended claims, and all technical ideas within the scope equivalent thereto are construed as being included in the scope of the present invention. Should be.
