Abstract

Injector feeder of loose materials, consisting of an injector chamber, into which the main air nozzle is inserted, equipped with an axially oriented air opening connected to the compressed air supply. The problem to be solved is the creation of a structurally complete device suitable for feeding powder materials. This is achieved by the injector chamber (1) being arranged in the upper central part of the disc body (6), provided with a central conical aeration chamber (7) with a smooth run-up to the inlet (8) into the injector chamber (1) and in the peripheral wall (9) of the disc body (6) there are radial aeration nozzles (10) oriented obliquely upwards from its lower outer part towards the conical aeration chamber (7), connected via connecting air channels (11) to the compressed air inlet (4), while the main air nozzle body is also arranged in the conical aeration chamber (7).

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injectable filler material comprising an injector chamber into which is provided a breather nozzle provided with an axially directed air hole and a connected compressed air supply.

According to the prior art, the injection chamber is formed by a tube into which an air nozzle is provided. Such an in-feed feeder is placed on top of a finished substrate in the form of a granular mass, the particles of which are entrained through the lower edge of the injector chamber with a stream of air exiting the nozzle. A certain disadvantage of such a dispenser is that it allows only granular, but not powdered, transport if it is not previously aerated. This requires additional equipment to mechanically loosen the powder mass.

The above-mentioned disadvantages are eliminated by the injector of the bulk materials according to the invention, characterized in that the injection chamber is arranged in the upper middle part of the cake body, provided with a central conical inlet opening with a continuous inlet to the inlet to the injector. The radially aerated nozzles connected to the lower outer portion of the aeration chamber and the telescoping air nozzle are arranged in a conical aeration chamber. An advantage of the injector feeder of the invention is that it forms a unitary structural unit directly connecting the aerator to the injector chamber, utilizing the aeration chamber space to accommodate the main air nozzle body, thereby making the device easy to handle and portable without additional equipment needed to prepare powders for transport. The reliability of the function of the aeration nozzles is further enhanced by the aeration nozzles being provided with a baffle in our inlet, which provides a rotational movement to the air flow exiting the aeration nozzle. It is also advantageous for the injector dispenser to function perfectly when the main air nozzle body is at an elevation provided by annular, nozzle-oriented, radially directed, upwardly directed auxiliary nozzles. These help the powder mass heated by the aeration nozzles to enter the injector chamber. An example of an embodiment of the injector feeder according to the invention is shown in the drawing, in which Fig. 1 is an elevational view of the injector feeder in partial axial section, Fig. 2 is a top plan view of the feeder and Fig. Fig. 1.

The injector feeder consists of an injection chamber 1 into which a main air nozzle 2 is connected. This is provided with an axially oriented air opening 3 connected to the compressed air supply 4. The injector chamber 1 is arranged in the upper middle part , in the present case, in the wear-resistant interchangeable housing 5 of the disc-shaped body 6. The disc-shaped body 6 wraps the central conical aeration chamber 7 with a continuous rise to the inlet 8d of the injector chamber 1. In the circumferential wall 9 of the disc-shaped body 6 are from the lower outer part of this a body 6 directed towards the conical aeration chamber 7 is formed by radially-aerated nozzles 10 connected to the air inlet 4 via a vertical pre-connecting channel 11 to a compressed air supply 4. The main air nozzle body 2 is arranged in the axis of the conical aeration chamber 7. All aeration nozzles 10 are provided at their inlet with a baffle 12, or have longitudinally formed curved grooves that bring the compressed air into rotation. If the manufacturing technology allows it, you may prefer to arrange the baffles at the outlet of the aeration nozzles 10, whereby more intense air growth is achieved. The body of the main air nozzle 2 is provided with lateral, radially obliquely directed, orifice nozzles 13, connected by a central air opening 3 of the main air nozzle 2, also to the inlet 4 of the pressure air. The disc body 6 has a notch 14 formed in the lower portion thereof, thereby facilitating the boring of the aeration nozzles 10. The compressed air inlet 4 opens into an annular distribution duct 15 which, through vertical connecting ducts 11, discharges the individual aeration nozzles 10 and 10. through one additional vertical switching channel 16, which has a larger diameter than the connecting channels 11, further through the horizontal support 17, as well as the main air nozzle 2. The nozzle of this nozzle 2 is lowered from below to provide as low resistance as possible to the injection. -tor feeder for transported powder.

When the injector feeder is laid down, the feeder is partially inserted into the substrate by its coil body 6 and the tip of the main air nozzle body 2, whereby the aeration chamber 7 is also closed from below. The aeration nozzles 10, by providing the flowing air of the aeration chamber 7, and the air coming out of the auxiliary nozzles 13, inject the aerated powder into the injector chamber, where the piping is received by displacing the main air nozzle 2 18 pneumatic conveying system.

The injector feeder according to the invention can be advantageously used in pneumatic systems conveying enamel powder for pre-electrostatic application as well as other kinds of bulk solids.
