Brief Description of Drawings
The invention will be better understood by an examination of the following description together with the accompanying drawings in which:
FIG. 1 is a side view of one embodiment of the invention;
FIG. 2 is an end view of FIG. 1;
FIG. 3 illustrates the plate in the filter chamber of FIGS. 1 and 2; and
FIG. 4 illustrates a second embodiment of the invention.
Description of Preferred Embodiments
Referring now to FIGS. 1 and 2, the dust collector, illustrated generally at 1, includes a filter chamber 3 having a first portion 3a and a second detachable portion 3b. The portions a and b may be connected together by collar means 4.
As can be seen, the filter chamber includes a top wall 5, a bottom closure 7, front and back walls 9 and 11 respectively, and opposing side walls 13 and 15.
Disposed within the filter chamber is a plate 17 which is better illustrated in FIG. 3. As can be seen, the plate 17 includes a plurality of openings 19. As seen in FIGS. 1 and 2, a separate filter bag 21 extends from each opening 19 in the plate 17 downwardly and into the filter chamber.
Duct means 23 are connected, at one end thereof, to opening 25 in side wall 13 of the top portion 3b. The duct means is connected, at the other end thereof, to a fan 27, whereby the duct means communicates the fan with the interior of the filter chamber. As can be seen, the opening 25 is disposed between the top wall 5 and the plate 17 of the portion 3b. The duct means 23 extend downwardly along side wall 13 to below the top portion 3b.
The dust collector is mounted on a collector platform 31, and the collector platform is mounted on a common platform 33 which includes wheel means 35 at one end thereof. The wheel means can include two or four tires as required. As can be seen, the mobile equipment 37, which in FIG. 1 is a surge bin, is also mounted on the common platform.
The mobile equipment has an inlet end 39 and an outlet end 41. Duct work 43 connected to an opening in a front wall of bottom portion 3a extends over and around the mobile equipment. Specifically, the duct work includes inlets 45, one of the inlets being disposed adjacent the inlet of the mobile equipment, another one being disposed adjacent the wheel means of the common platform, and a third inlet being disposed adjacent a conveyor 47 which conveys the output of the surge bin as is well known in the art.
In operation, the invention works as follows:
When transporting the mobile equipment and dust collector from one place to another, the top detachable portion 3b is removed and placed on another position in the platform, for example, at the extreme front end of the platform. With the top detachable portion so disposed, the entire load on the platform is a low load suitable for movement, for example, along highways. At the same time, although the top portion of the filter chamber is disconnected, the bottom portion, which includes the duct work 43, remains connected so it is not necessary to reconnect the duct work every time the equipment is used.
When the equipment arrives at the work site, the top portion 3b is placed on top of the portion 3a, and the collar 4 is used to airtightly connect the top portion to the bottom portion.
To cleanse the air when the surge bin is in operation, the fan is turned on and draws air from over and around the search bin through the inlets 45, through the duct 43, and up through the filter chamber. Dust is collected on the outside surface of the filter bags which, in the preferred arrangement, are similar to the filter bags as described in the afore-mentioned co-pending application. The air minus the dust passes through the filter bags and up through the openings 19 and thence into the duct 23 and to the fan 27 to be flown back out into the environment without the dust.
The member 500 (see FIG. 1) in the valve 51 is continuously rotatable either in the clockwise or counter-clockwise position as shown by the arrow. With this arrangement, dust which falls down to the valve will be explained from the filter chamber, however, air will not be allowed to enter the chamber through the valve.
To cleanse the filter bags, air under pressure is applied at inlet 53 between the top wall 5 and the plate 17, and the air under pressure is forced through the filter bags to blow the air off. The dust blown off will then escape through the valve 51.
As can be seen, the bottom closure is preferably in somewhat the shape of an inverted, truncated four-sided pyramid for reasons as described in the afore-mentioned co-pending application. The valve 51 is disposed at the bottom end of the inverted pyramid.
Turning now to FIG. 4, the arrangement shown in FIG. 4 includes a dust collector mounted on a platform with a crusher 37a. In the embodiment illustrated in FIG. 4, the top portion of the filter chamber is connected to the bottom portion by means of a hinge 57. In the transport position, the top portion is merely pivoted forwardly and downwardly so that it rests at the rear end 59 of the platform.
The FIG. 4 embodiment also includes a duct 43a extending over the conveyor 47. Further, in the FIG. 4 embodiment, a stand 49 is disposed at the front end of the common platform. Because the load on the FIG. 4 embodiment is heavier than the load on the FIGS. 1 and 2 embodiment, the wheel means 35 in FIG. 4 comprise three sets of wheels.
In all other respects, and in the method of operation, the FIGS. 1 and 2 and the FIG. 4 embodiments are identical.
The filter chamber is disposed in a vertical position for the same reasons as discussed in the aforementioned co-pending application.
Although several embodiments have been above-described, this was for the purpose of illustrating, but not limiting, the invention. Various modifications which will come readily to the mind of one skilled in the art, are within the scope of the invention as defined in the appended claims.
