Embodiment Construction

[0027] figure 1 and figure 2 A Venturi pump 2 is shown, which is designed to be used in a device for applying powdered paint products. The Venturi pump 2 extends along the main axis Y2 and comprises an outer body 20 . The outer body 20 includes a plurality of openings enabling the reception of different inlet and outlet conduits. The access duct comprises a first suction duct 22 having a generally cylindrical shape centered on the axis Z22. Upstream of the suction conduit 22 is connected to a reservoir A, which is not shown in the figure and contains a bed of fluidized powder.

[0028] Venturi pump 2 also comprises a first air injection connection 24 at its inlet. The connector 24 is connected to the pneumatic supply module B through a conduit 25 . On the end portion of the connector 24, a syringe 242 is arranged extending along an axis Y242, which coincides with the previously defined axis Y2. The syringe 242 is located on an extension of the connector 24 that is narro...

Abstract

A Venturi pump used for sucking powder from a supply, diluting the same, then feeding it to a gun via a conveyor pipe. The pump comprises an outer body, at least one powder suction duct, at least two air connections, of which a first air connection is capable of supplying an injector to create a vacuum inside the suction duct and a second air connection is capable of supplying a dilution air circuit separate from the powder flow. The pump including at least one powder outlet nozzle centered on an axis of diffusion, the inlet of which is located downstream from the first air connection and the suction duct. At least one protection barrier contains a non-return valve disposed inside the dilution air circuit and at least one outlet tip of the dilution circuit disposed around the nozzle and also connected to the conveyor pipe.

Description

technical field [0001] The invention relates to a powder pump using Venturi technology, which is used in particular in a method for the electrostatic application of powder coatings. Venturi pumps are relatively simple and inexpensive components. This mechanism is based on the Venturi effect, which consists in creating a vacuum by injecting high velocity air in order to draw powder from a reservoir which may contain a fluidized powder bed, and subsequently conveying the powder to the Pneumatic or electrostatic applicators. In order to more easily inhale the powder located at the bottom of the reservoir, air is injected into the interior of the reservoir to fluidize the powder. Depending on the supply distance between the Venturi pump, the applicator, and the length of the delivery pipe (which can vary from three to fifteen meters), this type of pump is capable of obtaining about fifty grams per minute to five hundred grams per minute. minutes of paint flow.
