Problems solved by technology

[0007] As a result, during continuous operation of the diaphragm pump, more and more powder builds up inside the delivery chamber of the diaphragm pump, which first reduces the suction power and eventually leads to clogging of the diaphragm pump
In addition, particularly in the case of very fine-grained powders, powder clumps form which impede the powder delivery or block the diaphragm pump
The blockage of the diaphragm pump cannot be eliminated by increasing the pumping power

Embodiment Construction

[0023] Diaphragm pump 1 includes surrounding working volume V 1 Or V 2 The delivery cavity 2 is defined on one side by a deflectable diaphragm 3. The diaphragm 3 can be brought into the suction position 4 and the pressure position 5. in figure 1 The middle diaphragm 3 is in the suction position 4 shown by a solid line. The oscillating offset movement 6 is produced by means of an eccentric drive device, which includes a motor 7 and a connecting rod 8.

[0024] An inlet valve 11 is provided on the suction side 9 of the diaphragm pump 1 and an outlet valve 12 is provided on the pressure side of the diaphragm pump 1. Both the inlet valve 11 and the outlet valve 12 are operated under pressure control by the powder / gas mixture delivered by the diaphragm pump 1, wherein the inlet valve 11 opens during the suction stroke of the diaphragm 3 into the suction position 4 and enters the pressure position 5 is closed during the pressure stroke, while the outlet valve 12 is closed during the...

Abstract

The invention relates to a diaphragm pump having a delivery space, which encloses a working volume, at least one deflectable diaphragm, which can be moved into a suction position and a pump position, an inlet valve arranged on a suction side of the diaphragm pump and an outlet valve arranged on the pressure side of the diaphragm pump. In order to make it possible to deliver fine-grain powder, for example, non-flowable powders having particle sizes of 0.01 mum to 100 mum, using a diaphragm pump, it is proposed that a gas feed for introducing a gas into the delivery space be arranged at the delivery space. In addition, the invention relates to a method for delivering fine-grain powder.

Description

Technical field [0001] The invention relates to a method for conveying fine-grained powders by means of a diaphragm pump having a delivery cavity surrounding a working volume, at least one deflectable diaphragm and a suction side of the diaphragm pump The inlet valve and the outlet valve provided on the pressure side of the diaphragm pump, the diaphragm can be brought into the suction position and the pressure position. Background technique [0002] The method for conveying the fine-grained powder is necessary, for example, to supply a quantitative amount of the fine-grained powder for the plasma coating process. Powder deposition and accumulation of powder must be avoided in the conveying path and pump, because otherwise the conveying of powder may be terminated. [0003] It is almost impossible to transport fine powder with a particle size of less than 150 μm with the known pump. Below this particle size, the adhesion of the powder particles is significantly improved. The area...
