Abstract

The invention relates to the field of welding and surfacing, and is intended for the dosing of bulk materials, which are fed to the surfacing zone. Productivity and metering accuracy is ensured by placing the drive blades 5 inside the hopper 1 with a replaceable bottom 3 have combined holes 4. The bottom of the bunker is stationary, and the blades 5 are arranged perpendicular to the bottom, ensuring periodic collapse of the material 9 arches above the holes 4, which can be expanded in the direction of spilling material. 4 hp f-ly, 4 ill.

Description

The invention relates to welding production, in particular, devices for supplying bulk fluxes of the charge during soldering or surfacing, and can be used in the chemical pharmaceutical industry for the dosing of bulk preparations.

The purpose of the invention is to simplify; designs and increase dosing performance.

Fig, 1 shows the dispenser in the oment of the supply of bulk material to etal, general view; Fig. 2 shows the bottom of the bunker in the form of a replaceable plate with holes; Fig. 3 shows a section in Fig. 1 (the initial state of dosing; S is the start of dosing; 6 is the movement of material during dosing; d is the end of dosing); Fig. 4 shows a plate for determining the maximum value of the vault of the dosing material.

The dispenser consists of a hopper 1, a drive 2 with an electric motor, a replaceable bottom 3 with openings 4 and blades 5 mounted rotatably around axis 6. The dispenser is mounted on product 7 with a ring 8 welded to it. In the bunker 1 there is a dosed bulk powder 9 forming over the openings 4 of the bottom 3 arches 10.

The device works as follows.

When the actuator 2 is turned on, the blades 5 begin to rotate around the axis 6 parallel to the bottom 3, moving material 9 along it. Formed in a state of rest above the openings 4, the openings 10 of the material 9 (Fig. 3) are shifted relative to the openings and collapsing. are.

With a uniform continuous movement of the blades, the dosed mater. Al is uniformly supplied by gravity into the holes. In this case, the vaults do not have time to form, since their bases, hanging above the holes, continuously collapse.

When the blades 5 cease to move over the openings 4 of the bottom 3, the arches 10 are formed again and the supply of material is stopped.

For powdery 1x fluxes, the diameter of the holes, depending on the resistance, can be set between 0.7 and 10 mm (since the diameter of the roof of the material depends on such factors as flowability, humidity, size

bunker et al., its size is determined in each specific case by experimental means using a control plate with a series of holes of different diameters). In order to determine the maximum diameter of the bulk material arch, a control plate with holes of different diameters is placed in the bottom in the bin. Ø The largest diameter of the hole, above KOTOpbJM, a set of data for these conditions is formed, is a critical size. The holes in the plate are smaller than this value so that 15 when the movement of the blades 5 stops, a set of bulk material is formed in the shortest possible time. From the holes above which, under the chosen conditions, the arch is formed, the optimal 20 is selected according to the amount of material poured out per unit of time during the movement of the blades 5. The diameter of the optimum hole for powdery fluxes with a bone bin up to 4 liters and the ratio of its diameter to height 1, 5-2.5 is in the range of 0.2-0.7 of the maximum diameter of the forked arch.

To prevent flux from hanging in

With 30 bottom holes 3, they are made to diverge down the bottom thickness. In order to evenly disperse the flux at the time when the blades are above the holes, the lower edges of the blades

35 sharpened.

The dispenser is convenient for delivering cutting materials to small parts that require simultaneous fluxing at different places along shaped contours.

40 Or in different quantities.

Making holes in the bottom along the shaped contours, you can get any form of filling the flux on the part. The finely ground powdery fluxes are well fed by this dispenser through openings with a diameter of less than 1 mm, which makes it possible to fill the flux along shaped contours on small parts.

50 The proposed design simplifies the dispenser, improves the operation reliability, expands the functionality, improves the metering performance.
