Description

(54) FLUSOAPPARAT

This invention relates to a welding technique, in particular, to devices for collecting flux that is not melted during welding. As a rule, flux apparatuses are used as part of welding installations.

A flux apparatus A-875 is known for collecting flux, which provides for the absorption of flux, due to the vacuum created in the bunker using an ejector. The exhaust air, together with the dust-like part of the flux, is produced in a hood equipped with a filter, where the dust particles are deposited and the air comes out .l.

Despite the measures taken to clean compressed air from moisture, the latter still has a certain humidity. The exhausted compressed air, in contact with dust particles, moistens them when deposited on the surface of the filter. As a result, a crust forms on the surface of the filter, which significantly complicates the passage of air, the degree of vacuum in the silo deteriorates and, consequently, the efficiency of suction of the flux apparatus deteriorates.

A flux apparatus is known, which comprises a flux bin, a filter with a spring-loaded plate, a pusher for shaking the filter, a sealing cap with a lid, a vacuum chamber, and an ejector C2}.

 The disadvantage of this flux apparatus is the low productivity in its use due to the long disassembly operation, performed e. mine because of the need for frequent shifts.

 filter when operating a flux apparatus.

The purpose of the invention is to increase productivity by improving the operational characteristics of the flux apparatus.

The goal is achieved by the fact that the vacuum chamber of a fluo apparatus containing a hopper for flux, a filter with a spring-loaded plate, a pusher

Claims (2)

20 for shaking the filter, a sealing cap with a lid, a vacuum chamber and an ejector, are provided with an annular partition mounted to form a cavity that communicates with the cavity of the sealing cap, and the cap of this cap is provided with a sealing element made in the form of a corrugated tube connected to mentioned by the cover 30 of the spring-loaded filter plate. the ejector is installed on the side walls of the annular partition and the vacuum chamber. FIG. 1 shows a fluorescent general view; in fig. 2 is a section A-A in FIG. one; on fig.Z - section bb in fig. 1. The flux apparatus has a flux hopper 1 provided with an inlet 2 for the flux-air mixture. In the upper part of the hopper 1 there is a vacuum chamber 3 provided with annular partitions 4 and 5 forming a cavity 6 communicating through the opening 7 with the cavity 8 of the sealing cap 9. The cap 9 is fastened on the bunker with the help of locks 10 and rests on the sealing gasket 11. In The upper part of the annular partition 4 has a ring 12 on which the strut spring 13 of the fabric filter 14 is attached, and the force of the spring 13 is transmitted to the filter 14 through the supporting plate 15 provided with Hyib windows. The filter 14 is attached to the ring 12 with a quick release clip. In the upper part of the encapsulation of its cap 9 there is a cup 16 with a lid 17 facing inwards, in which the shaking pusher 18 is moved. At the end of the pusher the push-in washer 19 is movably fixed, on which one end of the corrugated tube 20 is fixed. On the lid 17, sealing the internal cavity of the cap 9. On the side surfaces of the annular partitions 4 and partitions 21 an ejector 22 is fixed, and the inlet ports 23 of the ejector are placed in the ring of the shaped cavity 6 of the vacuum chamber 3. Actually The vector 22 consists of an air nozzle 24 and a diffuser 25 on which the air diffuser 26 is attached. The removal of the flux from the hopper 1 is performed through the throat closed with a stopper 27. The flux apparatus works as follows. The compressed air from the nozzle 24 is blown through the diffuser 25. As a result, the air in s & KyytwoA chamber 3 through the windows 23 is drawn into the ejector 22 and discharged outside. The ejected air flow is directed to the diffuser. The resulting vacuum in the cavity b hole 7 is created and in the cavity 8 of the cap 9. In connection with this "m" in the hopper 1, a vacuum is also created and the flux / air mixture is sucked through the hygiene hose, fluse intake and branch pipe 2 Flux Apparatus. Since in the bunker 1 there is a sharp increase in the volume of the flux-air mixture and an abrupt change in the direction of movement of this mixture, large particles of the flux fall to the bottom, and the air passing through the fabric filter 14 leaves dust on its inner surface. The filter 14 is periodically cleaned of dust, for which it is shaken. using a pusher 18. For this, the pusher 18 is sharply moved, which through the washer 19 acts on the plate 15 and the spring 13, precipitating the filter. When the pusher is 18 release-. under the force of the spring, the filter takes up its original position. Such abrupt movements of the filter cause dust to grow from the surface of the filter and clean it. The stretching corrugated tube 20 seals the cavity 8 of the cap 9. To replace the filter, release the locks 10, remove the cap 9 and, releasing the quick-release clamp, remove the filter 14 from the ring 12. After installing the new filter on the ring 12, fix it and fix the U1T cap 9 locks 10. The proposed constructive implementation of the vacuum chamber will allow. to improve sealing during assemblies and disassembling of a flux apparatus, necessary to replace the filter. The use of a sealing element in the form of a corrugated tube in the flux apparatus cap for sealing the movement of the shaking push rod also provides a deeper vacuum in the vacuum chamber of the flux appliance. Improving the sealing of the flux apparatus improves the cleaning of the flux and increases the efficiency of the flux apparatus. The use of the proposed flux apparatus will increase the productivity of labor when it is used as part of welding equipment. The invention includes a flux apparatus containing a flux hopper, a filter with a spring-loaded plate, a pusher for punching the filter, an air seal hood with a lid, a vacuum chamber and an ejector, characterized in that, in order to improve performance by improving the performance of the flux apparatus, the vacuum chamber is equipped with an annular partition installed with the possibility of cavity formation. Reported from the cavity of the sealing cap, and the cover of the sealing cap is provided with a sealing element made in the form of a corrugated pipe connected to the said cover and a spring-loaded filter plate, while the ejector is installed 58849076 on the side walls of an annular train- 1.
