14 Claims. (01. 183-67) j an improved separator for removing moisture from air or gas so that said air or gas maybe directed as clean dry air or gas to the point of usage.
Another object of the invention is the provision of a combined separator and automatic discharge whereby the moisture separated from the air or gas is automatically disposed of through suitable channels.
A further object of the inventionresides in the improved details of construction and arrangement of parts as are illustrated in the drawin and described in the specification.
Other objects and advantages of the present invention should be readily understood by reference to'the following specification considered in conjunction withthe accompanying drawing il-' lustrating one embodiment of the invention and it is to be understood that any modifications may be made in the specific structural details there shown and described within the scope of the appended claims without departing from or exceeding the spirit of the invention.
In the drawing: I
Figure 1 is an elevational View of the improved device of this invention.
Figure 2 is a substantialvertical section of the device shown in Figure 1;
Figure 3 is a sectional View taken on line 33 of Figure 2.
Figure 4 is a sectional View taken on line 4-4 of Figure 3.
Throughout the several views of the drawing similar reference characters are employed to denote the same or similar parts.
Also throughout the specification reference will be made to the separation of water and moisture from air under pressure, but it is notdesired to limit this structure tosuch use as the device may be employed with equal facility with gases; steam and other fluids of that nature.
As shown in the drawing the device comprises a casing having the upper end thereof closed as at 11 to form a dome. Interiorly of the dome is formed a flat surface 12 through which is tapped a perforation l3for pipe 14;. The pipe 14 is the discharge pipe'and conveys the clean dry air from the casing 10 to the point of use which may be any machine, unit or the like operated and controlled by compressed air. The lower end of the casingis flared to form a flange 15 and above the flange 15. a boss 16 is provided through which athreaded' perforation 17 passes for a pipel which connects the'casing 10 and pressure source. As seen in Figure 3 the threaded perforation 1'7 is extended beyond the pipe as a plane bore 19 which is tangent to the inner wall 20 of the casing. By this construction the compressed air is caused to swirl at a very rapid rate near the bottom of the casing 10. It has been found that the rapid swirling of the air precipitates a large majority of the moisture or liquid in the compressed air when'it ent'eredthe casing; By reference to Figure 2it will be'noted that the bottom of the casing is open'and is adapted to be closed by a head 21 which is provided with a flange 22similar to and abutting the flange 15 of the casing 10. A plurality of suitable similar clamp bolts 23 pass through the abutting flanges 15 and 22 for clamping them to one another. The upper surface of the head 21 which forms the floor or baseof the casing 10 is provided with a series'of declines and slopes 24 all draining-toward a port 25 formed through the head 21 at its thinnest part, By this construction'the moisture removed from the compressed air collects on the sloping base 24 and drains through the port 25 clearing the casing 10 of all foreign matter.
The air after having the major portion of the moisture removed therefrom by the swirling thereof passes upwardly through the casing to the discharge pipe 14. 'Theair however in its passage through the casing is intercepted by a 'plurality'of baffles 26, 27 and28 where additional moisture is removedtherefrom. These bafiiesare in the nature of graduatedperforated plates largest diameter holes. at the bottom: and the plate 28 with the smallest diameter'holes at the top while the'intermediat'e plate 2'7 has holes of a diameter between thatof the other holes. These plates each surround a support bar 29 depending from thetopof the dome 11 and is attached thereto by the screw threads 30 formed at the upper end thereof. The support bar 29 is thread-v ed substantially throughout its length-and has the baffles surrounding it at spaced intervals each. being held in place by a pair of nuts. 31 and 32.' The holding or clamping means for each of the baflies 26, 2'7 and 28 is the same and it is deemed suflicient if but one of :them be described in detail. Accordingly the baffle plate 26 has between its faces and the nuts 31 and 32 spiders;33' and 34 which are each provided with a central'boss 35 of a width or thickness greater than the thickness of the radial arms 36 that extend therefrom.
The outer ends of the arms 36 are connected by a ring 37 from which project lugs 38 which contact with the inner wall of the casing 10 and space the ring therefrom. By this construction each baflle unit consisting of a baffle plate 26, 27 or 28, a pair of spiders 33 and 34 and a pair of nuts 31 and 32 are clamped together between the said nuts 31 and 32 and is held against relative displacement with the rod. By reference to Figure 2 it'will be noted that the radial arms 36, ring 37 and lugs 38 are spaced from the sides of the baffle plates except at the center thereof where clamping contact is had between the plates and the adjacent faces of thecentral boss 35. This construction permits the baffle plates, which are bendable, to flex when the compressed air is passing through the casing to the point of use. As soon as the air pressure is cutoff the bafiles spring back to their normal position which is that shown in Figure 2. This flexing or fluttering of the bafiie plates flicks off any drops ofmoisture'that are collected thereon from the air as it passes therethrough causing said moisture to be collected on the base of the casing and discharged through the port 25. i
The head 21 has secured to its under surface a housing 39 forming a trap for the moisture and water and from which the said moisture and water are automatically discharged. The housing is formed at one side thereof with a vertical duct or conduit 40 communicating at one end with the-port 25 and at the other end with a horizontal ductor conduit 41 which terminatesin a second vertical. duct or conduit 42 emptying into a chamber 43. The chamber 43 has pivoted therein an inverted bucket 44 of a Specific gravity greater than the specific gravity of the water displaced thereby. The upper surface or top 45 of the bucket 44 is provided with a vent 46 for a purpose that will later appear. A hinge plate 4'7 secured to the top 45 of the bucket is pivotally secured at 48 to hinge lugs 49 carried by a ring 50. I
The ring 50 surrounds a ferrule 51 secured in an opening 52 formed in the under face of the head 21. The ferrule 51 has its opening at one'end restricted whichforms a valve seat for conical valve 53 secured to and extending from the hinge plate 47. The opening through the ferrule 51 terminates in a horizontal duct or conduit 54 communicating with a' discharge pipe 55 for car-' rying'off the precipitated moisture and water.
The operation of the trap is as follows;
The compressed air entering the casing by way of the pipe 18 is forced through the duct 40 into thehousing 39 and lifts the bucket 44 for causing the valve 53 to close the opening through the ferrule 51 and preventing escapeof air therethrough. i As the moisture and water drains through the said port andis forced thereinto-by the :air, the level gradually rises and any air with in1the trap housing as the horizontal duct or conduit141 is filled is forced from the interior of the bucket through the vent 46 therein. Continued rise of the water in the trap housing 39 eventually reaches-a level above the bucket 44 whereupon the bucket drops by gravity to the position shown in -Figure' 2, thereby'removing the valvefrom its seat and opening passagebetweenthe discharge pipe'55 and the interior of the trap housing 39. The compressed air now pushes all thewater withinthe housing through the said opening in the ferrule'through the discharge pipe 55 until the air engages the'inner surface of the bucket whereupon it is again lifted to close the valve 53 and seal the trap and easing fromthe atmosphere. It should be noted that this ejection of the water from the casing is momentary and does not operate to lower the pressure in the line.
