Description
BalgpumpeBellows pump
Die Erfindung betrifft eine große Balgpumpe zur Förderung von Dickstoffen, vorwiegend Flüssigmist, die von einem Getriebemotor mittels Exzenter und Pleuel angetrieben wird.The invention relates to a large bellows pump for conveying thick materials, primarily liquid manure, which is driven by a gear motor by means of an eccentric and connecting rod.
Sie ist vorwiegend für stationären Einsatz in Biogasanlagen geeignet. Druck und Sog werden mittels eines Reifens erzeugt, der als "Balg" bezeichnet wird.It is primarily suitable for stationary use in biogas plants. Pressure and suction are generated by means of a tire called a "bellows".
Schneckenexzenterpumpen und andere Verdrängerpumpen sowie Kolbenpumpen haben einen großen Kraftbedarf und Verschleiß, sie sind nicht trockenlauf- und fremdkörpersicher, sind teuer und haben keine lange Lebensdauer. Kreiselpumpen sind nicht selbstansaugend und haben keinerlei Rücklaufsicherung.Screw eccentric pumps and other positive displacement pumps as well as piston pumps have a high power requirement and wear, they are not dry-running and foreign body-proof, are expensive and do not have a long service life. Centrifugal pumps are not self-priming and have no backflow protection.
Diese Nachteile werden vermieden, indem wenig bewegte Teile vorhanden sind und ein Balg (Reifen) verwendet wird, der leicht austauschbar istThese disadvantages are avoided by having few moving parts and using a bellows (tire) that is easily replaceable
Die Erfindung besteht aus einem kompakten Ventilgehäuse (1), an dem der Reifen (= Balg (12)) mit dem Wulst einer Reifenflanke mittels Flanschen (4/5) eingespannt wird. Der andere Reifenwulst wird von einem Flansch gehalten, der als Pleuel (3) ausgebildet ist und durch einen Getriebemotor mittels Excenter bewegt wird.The invention consists of a compact valve housing (1) to which the tire (= bellows (12)) is clamped with the bead of one tire sidewall by means of flanges (4/5). The other tire bead is held by a flange which is designed as a connecting rod (3) and is moved by a gear motor by means of an eccentric.
Die geführten Ventile (6/7) sind druckmittelgesteuert und werden außerhalb des Ventilgehäuses (22) einzeln federbelastet, um eine sichere Schließung zu gewährleisten. Sowohl Saug- als auch Druckventil befinden sich auf einer gemeinsamen Drehachse deren Welle geteilt ist, damit die Ventilklappen unabhängig voneinander arbeiten können. Die Förderkanäle sind kurz gehalten und ohne störende Kanten, zudem werden sie von Ventilen nicht eingeengt. So wird wenig Reibung erzeugt und die Pumpe somit verstopfungssicher.The guided valves (6/7) are pressure-controlled and are individually spring-loaded outside the valve housing (22) to ensure safe closure. Both the suction and pressure valves are located on a common axis of rotation whose shaft is split so that the valve flaps can work independently of each other. The delivery channels are kept short and have no annoying edges, and they are not constricted by valves. This means that little friction is generated and the pump is therefore safe from clogging.

1. geringer Verschleiß1. low wear
2. trockenlaufsicher2. dry-run safe
3. fremdkörpersicher3. foreign body safe
4. selbstansaugend4. self-priming

6. preisgünstig6. inexpensive
7. energiesparend7. energy saving
8. extrem lange Lebensdauer8. extremely long service life
Ein Ausfuhrungsbeispiel der Erfindung ist ;n den Zeichnungen da/gcstellt und im folgenden näher beschrieben: An embodiment of the invention is shown in the drawings and described in more detail below:
Fig. 1: Vorderansicht mit Schnitt durch Welle 8a8b
2: Ventilgehäuse - Draufsicht
3: Schnitt durch die Pumpe in Stellung "saugen"
4: Schnitt durch die Pumpe in Stellung "drücken".Fig. 1: Front view with section through shaft 8a8b
2: Valve housing - top view
3: Cut through the pump in "suck" position
4: Cut through the pump in "press" position.
Fig.l zeigt den auf und ab beweglichen Pleuel (3), der fest mit der Flanschplatte (21) verbunden ist. Zwischen Flansch (4) und der Flanschplatte ist der obere Wulst (23a) der oberen öffnung(16a) des Balges(12) eingespannt. Der untere Wulst (23b) in der unteren Öffhung(16b) ist mittels Spannflansch (5) und Schrauben (9) fest mit dem Gehäuseflansch (20) verbunden. Die unabhängig voneinander beweglichen Ventilklappen (6/7 Ventilklappe 7 nur in Fkr 2 sichtbar) sind mittels Schwerspannstifte (10) mit der dazugehörigen Welle (8a 8b) verbunden und können somit mit den Federn (11) in der geschlossenen Stellung vorgespannt werden.Fig.l shows the connecting rod (3) which can move up and down and is firmly connected to the flange plate (21). The upper bead (23a) of the upper opening (16a) of the bellows (12) is clamped between the flange (4) and the flange plate. The lower bead (23b) in the lower opening (16b) is firmly connected to the housing flange (20) by means of a clamping flange (5) and screws (9). The valve flaps (6/7 valve flap 7 only visible in Fkr 2 ), which can move independently of one another, are connected to the associated shaft (8a 8b) by means of heavy-duty spring pins (10) and can thus be pre-tensioned in the closed position by the springs (11).
Fig. 2 zeigt das Ventilgehäuse (22) mit den halbmondförmigen Ventilklappen (6/7) von oben.Fig. 2 shows the valve housing (22) with the crescent-shaped valve flaps (6/7) from above.
Fig, 3 zeigt das mit dem Rahmen (1) verbundene Ventilgehäuse (22), welches rohrförmig ist und einen Einlaßkanal (14) und einen Auslaßkanal (15) besitzt, die durch die Zwischenwand (19) und den Ventilklappen (6/7) voneinander getrennt werden.Fig. 3 shows the valve housing (22) connected to the frame (1), which is tubular and has an inlet channel (14) and an outlet channel (15) which are separated from each other by the intermediate wall (19) and the valve flaps (6/7).
In Fig. 3 wird nun die Flanschplatte (21) mit dem zur Umgebung dicht abgeschlossenen Balg (12) vom Pleuel (3) in Pfeilrichtung (13) hochgezogen, so zieht der größer werdende Hohlraum (17) das zu pumpende Medium durch die sich öffnende Ventilklappe (6) des Arbeitsraumes (18) nach. Beim oberen Totpunkt des Pleuels (3) schließt die federbelastete Ventüklappe (6) des Einlasses.In Fig. 3, the flange plate (21) with the bellows (12) sealed off from the environment is now pulled up by the connecting rod (3) in the direction of the arrow (13), so that the increasing cavity (17) draws the medium to be pumped through the opening valve flap (6) of the working chamber (18). At the top dead center of the connecting rod (3), the spring-loaded valve flap (6) of the inlet closes.
In Fig. 4 wild durch Antreiben des Pleuels (3) in Pfeilrichtung (13) nach unten das im Hohlraum befindliche Medium durch die sich im Arbeitsraum (18) öffnende Ventüklappe (7) in den Ventükanal (2) gedrückt.In Fig. 4, by driving the connecting rod (3) downwards in the direction of the arrow (13), the medium in the cavity is pressed into the valve channel (2) through the valve flap (7) opening in the working chamber (18).
Sollen größere Saughöhen erreicht werden so kann in den Balg (12) ein Stützring (24) eingebaut werden, der ein nach innen ziehen des Balgunifanges verhindert. Zusätzlich wird am unteren Ende der Saugleitung des Einlaßkanals (14) eine Rückschlagklappe angeordnet.If greater suction heights are to be achieved, a support ring (24) can be installed in the bellows (12) to prevent the bellows from being pulled inwards. In addition, a check valve is installed at the lower end of the suction line of the inlet channel (14).
