Description

Title of the invention

Device for attaching support baskets schlauehförmiger filter elements.

Field of application of the invention

Me invention relates to a device for attaching support baskets schlauehförmiger filter elements with each other and with or on other components,

Characteristic of the known technical solutions

For filtering separators with cleaning of the filter bags by compressed air pulses, the filter hoses are installed and removed predominantly from the segregation side. This means that the filter tube together with its stabilization installations, for example the scaffold, must be pulled upwards out of the filter housing. Due to often limited space conditions as well as better manufacturability and transportability, it is necessary to divide the scaffold into individual shorter support baskets. These support baskets are then assembled during installation and installed with the filter tube over it through the Abscheiderdecke in the separator.

Known / are devices for connecting; Support baskets with each other, which are based on different mechanisms. The EB DS-QS 2 817 737 shows a solution in which the basket elements by means of several, independent of the basket elements, so loose, resilient clamps are held together. In DE-OS 2 846 029 two support basket parts are fastened to each other by means of a clamping ring., Wherein this connection allows a deflection of the filter element in the horizontal direction. Another possibility for connecting support basket parts with each other shows .die DE-OS 2,751,476. This is a device for connecting support baskets made of plastic. DE-GM 7 821 620 relates to a

 /

Support basket j which consists of several coaxially connected individual baskets, wherein the connection is made by means of a resilient ring and the locking of the mating ring is realized by means of a cranking of Stützkorblängsdrähte and protruding, bent longitudinal wires on the counterpart.

ITachteile of the above solutions are the high cost of producing the individual different and additional components and their assembly and occurring due to protruding or movable basket parts tissue wear.

Object of the invention

The aim of the invention is to find a device for connection and attachment of support baskets for filter bags, in which the above-mentioned specialist parts omitted without aids quick and easy to prepare and detachable and also for the connection of the support basket with the Abscheiderdecke and the support cage bottom is usable, wherein the support baskets coaxially aligned exactly and are locked so that a Filtermaterialverschleiß- is largely excluded by uncontrolled movements of the support baskets.

Explanation of the essence of the invention

The invention has for its object to provide a device for attaching support baskets for filter elements, in particular bag filter, which can be easily manufactured and solved without tools that allows no additional wear on the filter material, both for connecting support baskets with each other and can be used for attachment to the filter cover and the support basket bottom and allows the use of robotic technology in the manufacture of the support baskets by a minimized number of different components.

According to the invention, this object is achieved in that the

Ends of the support basket a flange-like ring is arranged, which has an inner and / or outer flanged edge to which the support rods, for example by means of spot welding, are fixed and on or at the bearing surface at least three uniformly distributed around the circumference fasteners in the form of. Tongues, tabs, cracking or the like are attached *,

When assembling the support baskets are plugged together with the fasteners and connected by opposite rotation.

embodiment

In the following, the invention will be explained in more detail with reference to an exemplary embodiment, "The accompanying drawings show?

on the remaining support surface 7 are ₃ as shown in Fig _e 1 to 7 ;, Various fasteners 8 attached. In Figo 1, an A-shaped bent tongue 8.1 is shown, which is inserted into the opposite slot 8,2 of the ring 4. Fig. 2 shows a similar embodiment, but with the difference that the z-shaped tongue 8.1 is arranged inside the support basket 3 on the ring 4 and can be used as a backup against sliding back of the attached support basket 3. Sine bayonet closure-like connection is shown in Fig. 3. In the solution shown in Fig. 4 arranged in the support surface 7 z-shaped tabs 8.3 similar to the tongues shown in Fig. 2 8.2 for attaching the support baskets 3 are used. At the inner edge 5 oil ring 4 are, as shown in FIG. 5, hook 8.4 and eyelets 8.5 arranged. Other possibilities of Stützkorbbefestigung show Figs. 6 and 7) in which at the inner edge 5 and the inner bead 6.1 crack 8.6 are attached.

For attachment of two support baskets 3 with each other, the support basket 3 on the Abscheiderdecke or the bottom of the support basket 3, the parts to be fastened are plugged together with the fasteners 8 and positively connected by counter rotating. The contact pressure achieved by the fasteners 8 is sufficient to prevent uncontrolled loosening, the connection and thus increased wear on the filter bag, leading movements of the support basket 3.
