Abstract

The pump handles material in dust form, delivering it into a pneumatic conveyor system. In the pressure chamber, at the end of the feed auger conveyor (5), is a loose sealing ball (3) forming a non-return valve, and pref. of soft plastics. The ball can be mounted in an open and removable cage (2), whose axis is at an acute angle to the plane of the auger outlet, so that when stopped the ball lies against an annular seat (4) of the screw conveyor outlet. The design gives better sealing and less wear than is the case with a conventional flap valve.

Description

Staubpumpe mit Kugelrückschlagklappe.Dust pump with ball check valve.

Stand der Technik: Staubpumpen-auth als Fullerpumpen bekannt, dienen der Einschleusung von Staubförmigen Gütern in ein Gasdrucksystem zwecks pneumatischer Förderung. Eine Schnecke drückt den Staub in ein Fördergehäuse, in welchem unter Einblasen von Druckluft mit Staubluftgemischt entsteht, welches über ein Druckgefälbe den Staub befördert. 3isher bekannte Systeme dichten den Schneckengang in das Druckgehäuse über flache Rückschlagklappen ab. Diese Rückschlagklappen bilden eine Art Schleusentür. Dieses System iat jedoch nicht dicht und wird mit fortschreitendem Verschleiss der beteiligten Teile immer undichter.State of the art: Dust pumps-auth known as fuller pumps, are used the introduction of dusty goods into a gas pressure system for the purpose of pneumatic Advancement. A screw presses the dust into a conveyor housing, in which underneath Blowing in compressed air mixed with dust air occurs, which is generated via a pressure vessel transports the dust. 3 Previously known systems seal the worm thread in the pressure housing via flat non-return valves. These non-return valves form a kind of sluice door. However, this system is not tight and becomes the more worn involved parts always leaky.

Vorteile und Beschreibung der Erfindung: Diese Nachteile verhindert eine Kugel, welche vorzugaweise aus einem geeignetem Kunststoff ist. Diese Kugel dreht sich frei im Materialstrom und ist bei Ausfallen desselben in jeder Lage absolut dicht.Advantages and description of the invention: These disadvantages are prevented a ball, which is preferably made of a suitable plastic. This bullet rotates freely in the material flow and is absolute in every position if it fails tight.

Die Kugel 3 liegt in einem Käfig welcher aus drei oder mehr Rundeisen 2 gebildet wird. Dieser Käfig ist von dem abnehmbaren Käfigdeckel 1 verschlossen0 Diese Käfigdeckel 1 ist mit einem Mittelloch versehen. Der Käfig ist mit einer geringen Neigung am Abschussring 4 montiert, damit die Kugel auch bei stillstand der Maschine am Abschlussring 4 durch ihr igengewicht aufliegt. Bei Einströmen der Druckluft über die Düsen 7 dichtet die Kugel zusaätzlich unter pneumatischen Druck ab. Im Betrieb drückt das Fördergut über die Schnecke 5 gegen die Kugel und öffnet gegen den pneumatischen Druck automatisch.The ball 3 lies in a cage which consists of three or more round bars 2 is formed. This cage is closed by the removable cage cover 1 This cage cover 1 is provided with a central hole. The cage is with a low Inclination mounted on the launch ring 4 so that the ball remains even when the machine is at a standstill rests on the locking ring 4 by its own weight. When the compressed air flows in The ball also seals under pneumatic pressure via the nozzles 7. in the Operation presses the conveyed material via the screw 5 against the ball and opens against it the pneumatic pressure automatically.
