Description

SEPARATOR FOR SUCTION APPARATUS
Technical Field The present invention relates to a separator for a suction apparatus, and more particularly, to a separator for a suction apparatus which effectively separates foreign matters or water included in air that is inhaled by a vacuum pump motor and discharges the separated foreign matters or water, to also discharge foreign matters or water that remains in the inside of the separator at a stop time of a vacuum pump motor.
Background Art
In general, as illustrates in FIGS. 1-3, a conventional separator for a suction apparatus inhales air and separates foreign matters or water included in the air to then discharge the separated foreign matters or water, and includes: a housing 10 having a hollow chamber 11 which is formed in the housing 10, and whose inner portion is penetrated in a up-and-down direction, an inlet 12 which is formed in the middle portion of the housing 10, and through which air including foreign matters and water is simultaneously introduced into the inside of the hollow chamber 11, a foreign matter outlet 13 which is formed in the lower portion of the housing 10, and through which the foreign matters and water separated from the inhaled air are discharged to the outside of the hollow chamber 11, and an air outlet 14 which is formed in the upper portion of the housing 10, and through which the air from which the foreign matters and water are separated is discharged; a vacuum pump motor 20 that seals the upper portion of the housing 10 tightly and is separably fixedly combined with the housing 10, to thus generate vacuum and a rotating force; a sealing plate 30 that seals the lower portion of the housing 10 tightly and is separably fixedly combined with the housing 10; a separation impeller 40 having a coupling boss portion 42 which is spaced from the sealing plate 30 at a given interval and is connected with and driven by a rotational axis 21 of the vacuum pump motor 20 at the upper-center of a rotating plate 41 which is rotatably arranged in the inside of the hollow chamber 11 in the housing 10, and a number of discharge guide blades 43 which are formed at the upper-edge of the rotating plate 41 and which scatter in an eddy ■ flow form the foreign matters and water which are introduced and ' fallen through the inlet 12 of the housing 10 and discharge the introduced foreign matters and water through the foreign matter outlet 13 of the housing 10 to the outside of the housing 10; a falling guide impeller 50 having a coupling hole 52 which is penetratively formed in the inside of a drum 51 which is rotatably disposed in the inside of the hollow chamber 11 of the housing 10 which is positioned at the upper side of the separation impeller 40, and which is connected with and driven by the rotational axis 21 of the vacuum pump motor 20, and a number of falling guide blades 53 which are formed in the outer circumference of the drum 51 and which intercept the foreign matters and water which are introduced through the inlet 12 of the housing 10 to then rise up and guide the intercepted foreign matters and water to fall down to the lower side; and a selective interception plate 60 which covers the upper portion of the falling guide impeller 50 and which is separably fixedly coupled with the chamber 11 of the housing 10.
If the vacuum pump motor 20 and operates to thus generate vacuum and a rotating force in the case of the conventional separator 1 for a suction apparatus, air including foreign matters and water is simultaneously introduced through the inlet 12 of the housing 10 into the hollow chamber 11, and the air including foreign matters and water introduced into the hollow chamber 11 is separated into the air, and the foreign matters and water by the gravitational weight . Thereafter, the air which has been separated from the air including foreign matters and water pass through the falling guide blades 53 in the falling guide impeller 50 and the selective interception plate 60 and is discharged to the outside of the housing 10 through the air outlet 14 of the housing 10. In addition, the foreign matters and water which have been separated from the air including foreign matters and water fall down to the separation impeller 40 and thus are scattered in an eddy flow form by the discharge guide blades 43, to then be discharged through the foreign matter outlet 13. Here, the foreign matters and water which are introduced through the inlet 12 of the housing 10 to then rise up are intercepted by the falling guide blades 53 of the falling guide impeller 50 and the selective interception plate 60 and fall down to the lower side, to thus be discharged through the foreign matter outlet 13 of the housing 10 by the separation impeller 40.
However, in the case that operation of the vacuum pump motor 20 stops in the conventional separator 1 for a suction apparatus, the separation impeller 40 that is connected with and driven by the rotational axis 21 of the vacuum pump motor 20 also stops. Accordingly, the foreign matters and water remaining in the inside of the chamber 11 of the housing 10 are introduced between the selective interception plate 60 and the separation impeller 40, to then be piled and hardened. Thereafter, when the separator 1 is made to re-operate, an overload is applied to the vacuum pump motor 20 and thus operation of the vacuum pump motor 20 stops. As a result, operation of the suction apparatus stops .

Here, a drain hole 131 is penetratively formed in the sealing plate 130 and a check valve 170 is installed in the drain hole 131. Accordingly, the foreign matters and water remaining between the separation impeller 140 and the sealing plate 130 are discharged to the outside of the housing 110 at the time when the vacuum pump motor 120 stops, and the check valve 170 is closed by vacuum at the time when the vacuum pump motor 120 operates to then discharge the foreign matters and water separated from the air in the housing 110 through the foreign matter outlet 113 to the outside of the housing 110. The rotating plate 141 of the separation impeller 140 is preferably formed in a linear fashion in cross-section, in a manner that foreign matters and water can flow down smoothly when the rotational axis 121 of the vacuum pump motor 120 rotates and stops.
In addition, as illustrated in FIG. 7A, the rotating plate 141 of the separation impeller 140 may be configured to have an inclined surface 141a on the upper surface of the rotating plate 141 in a manner that foreign matters and water can flow down smoothly when the rotational axis 121 of the vacuum pump motor 120 stops.
In addition, as illustrated in FIG. 7B, the rotating plate 141 of the separation impeller 140 may be configured to have a penetration hole 141b which is formed to penetrate through the rotating plate 141, as being the case. Accordingly, foreign matters and water can flow down to the sealing plate 130 through the penetration hole 141b of the separation impeller 140 when the vacuum pump motor 120 stops. It is preferable that a discharge guide groove 132 is formed on the upper surface of the sealing plate 130 and thus foreign matters and water remaining between the separation impeller 140 and the sealing plate 130 can be discharged smoothly through the drain hole 131. The check valve 170 is protrudingly formed on the bottom of the sealing plate 130 and the drain hole 131 is extended in the inside of the check valve 170. The check valve 170 includes: a coupling protrusion 171 having an insertion groove 133 which is formed in the lower end of the drain hole 131; an opening and closing damper 172 which is inserted into the insertion groove 133 to open and close the coupling protrusion 171 and the drain hole 131; a valve socket 173 which supports the edge of the opening and closing damper 172 and is detachably supportably combined with the coupling protrusion 171, in which a discharge hole 173a which communicates with the drain hole 131 of the coupling protrusion 171 is formed in the inside of the valve socket 173; and a discharge hose 174 that is combined with the valve socket 173 to communicate with the valve socket 173 to thus guide foreign matters and water.
Operation of the separator 100 of the suction apparatus having the above-described structure follows.
If the vacuum pump motor 120 is made to operate, and thus the separation impeller 140 and the falling guide impeller 150 which are combined with the rotational axis 121 of the vacuum pump motor 120 is made to rotate, to accordingly make the chamber 111 of the housing 110 become at a vacuum state, air including foreign matters, water, etc., is introduced into the chamber 111 from the outside of the housing 110 through the inlet 112 of the housing 110, and the air including the foreign matters, the water, etc. , which is introduced into the chamber 111 is separated into air, foreign matters, water, etc., by the gravitational weight.
Thereafter, the air which has been separated from the air including foreign matters and water pass through the falling guide blades 153 in the falling guide impeller 150 and the selective interception plate 160 and is discharged to the outside of the housing 110 through the air outlet 114 of the housing 110. In addition, the foreign matters and water which have been separated from the air including foreign matters and water fall down to the separation impeller 140 and thus are scattered in an eddy flow form by the discharge guide blades 143, to then be discharged through the foreign matter outlet 113. In this case, the opening and closing damper 172 of the check valve 170 is closely attached to the drain hole 131 of the sealing plate 130 tightly. Accordingly, air, foreign matters or water is not introduced through the drain hole 131 from the outside of the housing 110.
Here, the foreign matters and water which are introduced through the inlet 112 of the housing 110 to then rise up are intercepted by the falling guide blades 153 of the falling guide impeller 150 and the selective interception plate 160 and fall down to the lower side, to thus be discharged through the foreign matter outlet 113 of the housing 110 by the separation impeller 140.
Meanwhile, if the vacuum pump motor 120 stops and thus the separation impeller 140 and the falling guide impeller 150 which are combined with the rotational axis 121 of the vacuum pump motor 120 stop, to simultaneously make the vacuum state of the chamber 111 of the hosing 110 released, the opening and closing damper 172 of the check valve 170 is detached from the drain hole 131 of the sealing plate 130 and thus the drain hole 131 is opened. As a result, foreign matters and water remaining between the separation impeller 140 and the sealing plate 130 are discharged through the drain hole 131 to the outside of the housing 110. Therefore, in the case that the vacuum pump motor 120 is made to re-operate, the separator 100 operates smoothly well without making a trouble since there is no portion which makes a friction with the separation impeller 140. As described above, a separator for a suction apparatus according to the present invention includes a drain hole and a check valve so that foreign matters or water that remains between a separation impeller and a sealing plate which are positioned in the inside of a housing can be discharged to the outside of the housing and removed from the inside of the housing at a stop time of a vacuum pump motor. Accordingly, since the separator can be maintained cleanly, the efficiency and maintenance in use of the entire suction apparatus can be enhanced.
However, the present invention is not limited to the above embodiments, and it is possible for one who has an ordinary skill in the art to make various modifications and variations, without departing off the spirit of the present invention.
Industrial Applicability As described above, the present invention provides a separator for a suction apparatus which effectively separates foreign matters or water included in air that is inhaled by a vacuum pump motor and discharges the separated foreign matters or water, to also discharge foreign matters or water that remains at a stop time of a vacuum pump motor.
