2 Claims.
The present invention relates to apparatus for receiving strippings of cotton and the like pneumatically removed from the working cylinders of a carding engine.
The purpose of this apparatus is to separate the recoverable cotton fibre so far as possible from air and dirt, and to recover this fibre in a form which makes it available for reuse or otherwise merchantable.
For the accomplishment of this purpose I have provided a receiver of the stationary type into which the air-borne cotton fibre is discharged, and have apportioned and screened the delivery from such a receiver in a manner to permit the escape and discharge therefrom of conveying air and light particles of dirt therewith, but to separate and collect the recoverable cotton fibre as stripped.
In the drawing illustrating the preferred form of the invention, Fig. 1 illustrates a section in elevation of my improved receiver; and Fig. 2 is a detail illustrating a cross-section of the same apparatus upon the line 2-2 of Fig. 1.
As indicated in the illustrated embodiment of the invention, the air-borne cotton strippings are delivered to the receiver through a suction pipe III. This pipe enters the receiver at the top centrally thereof as shown in Fig. 1, and the air and solid material conveyed therein is discharged I downwardly toward the bottom of a generally cylindrical compartment l2. As indicated in the drawing, this compartment is closed at the top through an arched cover member l4, with which the suction pipe I0 is connected through a flange I6. and a peripheral side wall 29 extending upwardly throughout the major portion of its length, but terminating adjacent the upper portion to pro-- vide an opening 22 extending completely around the upper portion of the chamber and screened at 24, the upper portion of the screen being attached to a ring 26, and the lower portion being attached directly to the chamber wall 20. The height of this opening is so proportioned that air entering the chamber through the suction pipe is caused to pass outwardly through the surrounding screened opening, together with such finely divided solid material as may pass therewith through the screen. The recoverable cotton fibre in the form of strippings passes directly downward and is collected at the lower portion of the imperforate chamber without in great measure contacting the screen at all. Obviously to some extent this must be accomplished by so gauging the velocity of the incoming air that It is provided with an imperforate bottom it is insufiicient to cause the bulk of cotton fibres to lodge on the screen, but is of sufficient velocity to pass therethrough carrying small particles or fiour therewith. This tendency on the part of the air to bypass the collecting chamber and pass outwardly through the opening is created by appropriate suction means which are connected with an annular air chamber 30 formed by the outer wall 32 of the receiver which completely surrounds the inner wall 20 and extends downwardly thereabout and then outwardly through an opening 34 communicating with a suitable suction pump (not shown). This communication between the annular chamber and suction opening may be accomplished through a perforated delivery pipe 36, screened at 38 to remove dirt and solid particles from the air before it passes to the suction pipe. As indicated clearly enough in Fig. 1, there is free communication between this annular chamber and the screen suction pipe, the dirt being screened out dropping to the bottom of a separate chamber 40 surrounding and below the pipe.
Access both to the upright cotton chamber and the dirt collection chamber may be had by a cover member 42 which is removably clamped to a flanged opening 44 by clamping members 46 and sealed in place by compressible sealing strips 48, as will be evident. Releasing and removal of this cover member exposes the collection of cotton in the bottom of the upright chamber and permits cleaning of the dirt from the lower and unconnected outlet chamber if so desired. It will be obvious that there is no intercommunication between the cotton chamber and the air outlet chamber except through the upper opening to prevent cotton collected in the bottom portion of the upright chamber from being drawn by suction into the collecting chamber.
As will be evident, this type of receiver or separating apparatus is simple and compact in its nature, and involves no moving parts which are capable of becoming inoperative through collection of cotton or dirt thereon. It has been found markedly efficient in its ability to separate recoverable cotton strippings from the air current and contained dirt when removed from the carding apparatus.
What is claimed is:
1. A receiver for air-borne fibre, comprising an upright chamber closed with an imperforate wall throughout the greater portion of its length and with a perforate wall throughout the upper portion of its length, an annular air chamber surrounding the receiving chamber throughout its complete length, means for introducing air with fibre therein at the upper portion of the chamber and for causing the air and lighter particles to discharge through the perforate wall into the annular surrounding chamber and the larger fibre to drop downwardly to the bottom of the receiver and cease to be air-borne, removable means for sealing the bottom portion of the receiving chamber, means in communication with the annular air chamber for Withdrawing air from the bottom portion thereof, and means for screening the air outlet.
2. A receiver for air-borne fibre, comprising an upright chamber closed with an imperforate wall throughout the greater portion of its length and with a perforate wall throughout the upper portion of its length, an annular air chamber surrounding the receiving chamber throughout its complete length, means for introducing air with fibre therein at the upper portion of the chamber and for causing the air and lighter particles to discharge through the perforate wall into the annular surrounding chamber and. the larger fibre to drop downwardly to the bottom of the receiver and cease to be air-borne, removable means for sealing the bottom portion of the receiving chamber, means in communication with the annular air chamber for Withdrawing air from the bottom portion thereof, means for screening the air outlet, and means for removably sealing the screen chamber to obtain access 15 thereto for the removal of dirt.
