TANK, ESPECIALLY FOR USE AS A BUFFER TANK IN AIR SYSTEMS

OejikendteteMh

The invention relates to a tank, in particular II! fe back as a buffer tank in the compressed air load, which tank comprises an outer tank should to form an inner cavity, and with pipe connections for the air inlet and outlet, and wherein the tank consists of two tanks have to share with each one tiislutningssfuds which must portions are dimensioned to sammeh ^ efses ten formation of the internal cavity.

Shells of this kind is preferably used in compressed air systems, where there are pressure variations in that the air by passing through such a tank is equalized trykvabatonefne, i.e. udjævnef trykvanatiorieroe on the discharge side. To which, the idea opmagasinerer desn excess trykluiSxkåpaeiteh when air consumption periods are reduced relative file compressor kapapitaf.

It includes such bufferlanke in all systems with varying air demand.

From US 2010/0075200 Eel <Ende an example of eft tank for storing gas under high pressure, which tank comprises a iankskal teh, forming an internal lumen and including pipe connections for the gas inlet and discharge, which tank be made up of two shell portions, each a connecting stub ,, and wherein skaldeten is sized hl saromensvejses TLI to form the cavity.

The disadvantage of the known thought is the not the sufficiently dampens sound that occurs when pulsating air tightens through the tank, then the parts will be set to vibrate, thus producing a rowers or less vigorous and generiode noise.

The purpose of the invention

The invention aims to remedy this deficiency and improve the possibilities of adapting tanks conditions, thus ensuring the best possible attenuation Oden that it changes the buffer function.

Pete is achieved according to the invention, by a tank in which, in connection to the studs within the cavity are mounted baffles, which forms the bottom in the way with pass-through openings formed to guide tongue partition the lot file striking the piespladerne.

In this way, the sound will be muted upon impact against prelplsdeo, respectively by supply and discharge. Tank Space will also act as the known buffer tanks. For further reduction can be one tank compartment hospitalized absorbing material behold like a sponge or the like;

As disclosed in claim 2, inserting one or Liere sections with damping properties between the shell parts will be in a surprisingly simple way to dimension thought banquets conditions, and thus achieve a tank, etc. will give the opfimåle: noise reduction.

As disclosed in claim 3 s, leveling passages in each of the damping plates symmetrically to the plate center, we! at tanks with several: sections could be attenuated by shifting the maximum of the holes relative to each other by rotating the individual plates such that the air is forced to a centrifuging which will incorporate sfømftlhgåBhefgl. This will ensure m rfiakphiaj soundproofing.

Do you know the meaning of claim 4 of designing one shell part and damping section with an outer rim that can enclose the adjacent shell portion and at the same time provide the other shell part and dimming sections with: m inner rim, and jade these circles run in a spaced, will form an abutment surface.

: Hereby, the parts could be a kit which allows for construction of a buffer tank with a dæmpniogseffekt adapted imi conditions *

When, as in ombandfet. S claim that dlmertelønere and shaping skaldetene and attenuation sections with circular installation surfaces of the same diameter, the parts could be assembled to form the finished tank.

As disclosed in claim 6 that produced ice parts in plastic, the parts can be partly carried out in a vibration damping material could partly assembled by sammensvejsnlng ai the parts.

At that address! in claim 7, to provide the bearing surface with a tongue and a cooperating groove, will be referred to f claim 8, sømmensvefse to those portions and thus Upon spin welding.

Finally, we know that deal! In claim 9, to design the air flows in the tank so as to extend around the center line of the tank room, achieve effective and a komoaKt tyddærøpniog design, the respiratory tract will meander through the openings dg consume energy.

Description sf udføreiseseksemofeme That first Udførelseseksemp! L nail will felive besteveti is at% 1-3 tank.

This tank is constructed of two parts to be halvkugleforroede 1 and 2 which are assembled to form an enclosed inner cavity 11 "

Each shell 1 and 2 is provided with either an inlet or an outlet, which is done via the connecting pieces S, a: Preferably, the shells are mounted on the apex

Each of these connection pieces 3: W, as shown peftg, 2 and 3 are formed as outwardly projecting connecting pieces, which can be provided with a not shown internal thread for saMrrie ^ rønfcg with trykiurtsanlæggei inside skaldelens cavity 11, the spigot is provided with a dividing wall 14 which at the end is closed by a plate 4. Furthermore, hulier 5 formed through the partition wall 10 with a view to the air passage

Purpose: to this arrangement, by forming both a damping of the connecting stub to 3, tllledes compressed air, whose flow path is indicated by the 'broken line 12.

By air inlet ten! 3 spigot air will flow against the inner side of the plate 4, which will act as a preiplade and thus dampen the air velocity and the recording energy from the air and thus dampen the pulsation.

After the air in the suppressed state pass across through the openings S and Into the cavity 11th

In tankrummeis opposite end which is at the top in the drawing, the air will abut against the one mounted prelpla.de 4 that will further attenuate the pulsation. After that air movement across gennemskiHevæggens 1G openings 5 ​​and out through the outlet 3. The air will thus be attenuated while the tank space 11 to act as a buffer chamber.

This will resulere in a dampening of luftpulsationen and thus a significant reduction in noise emissions as the energy in the air will be reduced through these attenuation and afbopingsmidler.

The parts; is preferably produced by casting in one kunststot édfn per åelv will constitute err damping factors may be due to the material's insignificant egensvmgning which iuftpuisationen VJI have on the relatively soft material.

The assembly of the two shell portions 1 oak 2 will now be described

Each shell part are provided at their open end of the circular increment of the same diameter so as to we! able to bear against each other, with their end faces will be the bearing surface 13. In order to ensure that the parts are not displaced or deformed during use, there is a pi outside of the one shell part 1 formed an outer rim 6; which extends about the second shell portion 2 shown in fig..2 sorn.

In order to weld these elements and 2, there may, as shown in rig. 2 and 3, be designed in one fjerlsgnende maieriaiefprøgelse S of the one shell part 1 and, if a groove 8 on the second shell 2 such that by a rotation welding will occur © s melting tjsfen § and thus a welding together of the two parts 1 and 2

To further strengthen the joint, may be made, as shown in Fig. 2 and 3, on the supports © shell portion 2 may be formed an inner peripheral% which may be either m against the upper shell portion 1 inside surface.

Pi this way, there is formed an enclosed tank, as prepared 1 will be weldable plastic, stretch © g with a high attenuation rate due to the inner dæmpningsforanstaitninger. If required, can be observed in the damping material ianktummei for further attenuation. This d ^ mpdingsef ^ kt is obtained ydéh to bufféregenskaberne is affected.

Then we! it tig. 4 * 8 in the example shown, a buffer tank will be described.

Also this tank is built in shell parts 1 and 2, which is identical with the pi tig. 1-3 tank. Between these must share 1 and 2, in the example shown inserted two damping sections 20th

Each of these: sections 20 consisting of fen circular plådedel 21, as shown in ft g. 5 and Sv Along piadedetens 21 penfen is cer-shaped peripheral portion 8 by 1 its shape is identical to the opposite party on the upper shell part 1, in pladedeten 21 there are formed openings 22, which preferably extends at the same distance from the plate center. In this way, the individual sections 20 prior to the welding, are rotated relative to each other eg ;, thereby extending the air flow path 12 through iankrummef 11.

The manufacture and assembly of the parts 2 and 20 are similar to dies on Fig. 1-3-described tank.

The purpose of the insertion of the attenuation sections 20 is to dampen yderigere and by choosing the number of sections to produce a buffer tank with a specified attenuation rate.

Hereby it is in a surprisingly simple rnåde possible to adjust the damping level is filled as needed, while maintaining the desired buffarefekt.

The flow of air through the tank with two damping sections 20 will. as indicated by dotted: line 12 of FIG. 6, be dampened partly affected by attacks against preipladen 4 at iuMlednlngen know spigot 3 at anslåg against dam plate 21, the deflection then at ports 22:01 additional plate 21 with openings and finally with preipladen 4 (after which the air will leave the tank through efgangssfudsen third

This combination of 'pulsation and changing sfromnfngsv ^ one will effectively smooth the air being pulsation and thus dampen the noise, fdeftil comes the material's ability ten! are to absorb vibrations due to its relative resilience.

manufacture of plastic has the obvious advantage that the tank is not particularly susceptible to transmissible external influences dg tédenmåjlæ down for wrestling.

in the shown example there are shown two damping sections 20, but this is merely to illustrate the principle in the tank. There will naturally be able to be inserted from one or more sections to obtain a specific dærnpnlngseffekt.
