Definitions
- Device for protecting an air filter in particular, a generator, comprising parts to be assembled radially on the filter.
- the invention relates to the field of the design and production of air filtration equipment and accessories. More specifically, the invention relates to the protection of air filters, in particular for large capacity filters such as those mounted on high power generators.
- the invention applies in particular to generators, but can also be applied to other types of gear requiring filtered air intake such as marine engines, industrial engines ...
- the generators implement combustion engines powered by a fuel / air mixture, the air being admitted through the inlet duct of a turbo-compressor.
- This intake duct is provided with an air filter.
- the group generally has a housing for receiving the air filter.
- the housing as shown in Figure 8 includes a cover 81 which once removed allows the extraction or implementation of a filter.
- this technique involves the insertion of the filter in the housing along the longitudinal axis of the latter.
- a case conventionally has a length of 70 cm, this length being approximately that of the filter. It is therefore necessary to have a space of twice the length L: once for the bulk of the housing, and once to present the filter in front of the housing when placing the filter in the housing. In some cases, this operation is made tedious or impossible, due to the presence of obstacles (such as machinery and / or parts of building) in the immediate vicinity of the generator.
- the assembly of the housing / filter assembly is considerably simplified, the filter outlet duct being intended to be fitted directly onto the compressor duct of the unit.
- the one-piece casing / filter assembly proves to be a relatively expensive part.
- the filter is mounted in a housing consisting of two parts hinged together.
- the filter is installed in one of the housing parts, the other part being folded over the first to close the housing.
- a ring provided with ramps present at the bottom of the housing is then actuated to cause a longitudinal wedging of the filter in the housing and bring the seal of the upper flange of the filter in a compressed position against the housing. It is noted that calibration and the tightness of the filter in the housing are obtained using a specific piece that tends to increase the complexity of the whole and its manufacturing cost.
- the housing has a sleeve to be fitted on the equipment. It is therefore understood that the housing exerts a support function of the filter on the equipment, the filter not being mechanically in cooperation with the air intake of the equipment.
- the filter is fitted on the duct of the compressor of the group and, optionally, a bracket removably secured to the frame of the group holds the filter at its end opposite the fitting by exerting a bearing on the rear flange of the filter.
- the mounting of the filter according to this technique is particularly simple and fast.
- generators manufacturers want to offer or have modular solutions, combining the simplicity of mounting the filter according to the technique "pending" and the ability to protect the filter in case of outdoor use.
- the invention aims to provide a mounting technique of an air filter, for example that of a generator, which allows to go easily from a protected configuration to an unprotected configuration of the filter.
- the invention also aims to provide such a technique that is practical to use.
- the invention also aims to provide such a technique that eliminates any constraints of reduced space around the equipment on which the filter must be mounted.
- Another object of the invention is to provide such a technique which does not produce an excess of waste during renewal of the filters.
- Yet another object of the invention is to provide such a technique which is simple in design, easy to implement and inexpensive to produce.
- the offer of manufacturers and / or distributors of equipment may include a basic configuration corresponding to groups "pending", with the optional protection device according to the invention.
- the "radial" mounting of a protection device according to the invention allows mounting in congested environments. Indeed, unlike the solutions of the prior art that it is necessary to have a minimum space in front of the housing to insert the filters longitudinally (they can reach lengths of 70 cm or more, which implies a space of at least equivalent length in front of the opening of the housing in order to be able to present the filter), the fact of being able to bring the protection device radially relative to the filter (possibly already in place) frees itself from the considerations of available space .
- At least one of said parts has setting and / or positioning means intended to cooperate with corresponding forms of said filter.
- the housing formed by the parts can thus be reliably held on the filter.
- said wedging and / or positioning means advantageously comprise longitudinal holding means intended to cooperate with at least one of the ends of said filter.
- said one or more parts have at one of their end a flange extending radially and intended to form a longitudinal contact on a flange of said filter.
- said one or more parts also have at one of their end a groove forming a housing for a flange of said filter.
- At least one of said parts has at least one air intake window.
- said window or windows are arranged so as to allow radial admission.
- said window or windows are arranged so as to allow longitudinal admission.
- the device comprises removable securing means of said parts together.
- these comprise at least one clamping collar.
- these are carried by said parts and are preferably latching means of said parts together.
- said parts are identical to each other.
- FIG. 2 is a perspective view of a device according to the invention, mounted on an air filter, according to a first variant
- FIG. 3 is a perspective view of a device according to the invention, mounted on an air filter, according to a second variant;
- Figure 4 is a detail view of an end of a portion of a device according to the invention;
- Figure 5 is a detail view of another end of a portion of a device according to the invention;
- FIGS. 6 and 7 are perspective views, from two different angles, of a method of mounting a device according to the invention;
- Figure 8 is a view of an air filter assembly in a housing according to the prior art.
- the principle of the invention lies in the fact of designing a protective case of an air filter in the form of parts to report in a radial direction relative to the filter.
- FIG. 1 shows a filter 1 (conventionally having a generally cylindrical shape forming a cross-section in the view of FIG. 1) with respect to which a protection device according to the invention consists of of parts 2 is presented.
- the parts 2 are intended to be mounted on the filter by relating them in the directions indicated by the arrows F1 and F2, that is to say say in radial directions with respect to the filter.
- housing parts are mechanically independent of each other (or each other) before assembly on the filter. Thus, it preserves the possibility of manufacturing simple and inexpensive design parts (as opposed to parts interconnected by a hinge for example).
- the assembled parts 2 form a housing whose first portion 21 has a diameter substantially equal to the outside diameter of the filter and a second portion 22 has a diameter greater than that of portion 21, a gap air circulation being formed between the portion 22 and the air filter.
- the parts 2 are preferably identical to each other so as to be manufactured in series with a single tool, for example by molding plastics material. However, it is conceivable that the parts 2 are distinct, one of them only having air inlet windows 23 in a radial direction (FIG. 2).
- the parts 2 (or at least one of them) have windows 24 for admitting air in a longitudinal direction (FIG. 3).
- the parts 2 (or at least one of them) have positioning and / or wedging means intended to cooperate with the filter.
- these means are provided for positioning and maintaining in position on the filter parts 2 both in the longitudinal direction and in a radial direction of the filter.
- the parts 2 have: - at one of their end, a flange 25, extending the portion 21 and extending radially so as to create an annular longitudinal bearing surface intended to be pressed against the front flange 11 of the air filter; at the other end, a groove 26 for receiving a flange 121 that has the rear flange 12 of the air filter.
- the flange 25 extends in a first plane, that the groove 26 extends in a second plane corresponding to the bottom 260 and that these first and second planes are end planes of the parts 2.
- the flange 25 in particular is therefore part of a terminal plan of Parts 2.
- the parts 2 do not extend longitudinally beyond the flange 25 and, in any case, do not have, beyond the rim 25, mechanical cooperation means with the intake duct of the equipment to which the filter is attached.
- the flanges 25 of the parts 2 together constitute an annular support zone on the upper flange 11 of the filter
- this annular support zone extends radially so as to provide a recess of sufficient diameter to form a passage for a sleeve 110 secured to the upper flange 11 of the filter and extending from the upper flange.
- the assembly of the parts 2 thus formed on the filter is carried out simply, this by engaging the groove 26 of one end of the parts on the flange 121 of the filter.
- the length of the parts 2 is of course provided so that, by engaging the groove 26 on the flange 121, the flange
- the groove 26 contributes to the maintenance of the parts 2 on the filter and is moreover a means for forming a tight connection between the parts 2 and the filter (a seal that can possibly be attached to the filter). inside the groove especially to absorb any vibrations).
- the parts 2 are then secured together by means of removable means so that the parts 2 can be easily separated from the filter during the renewal thereof.
- clamps 3 are attached around the parts 2, one at the portion 21 and the other on the portion 22 adjacent the flange 12.
- the securing means are integrated in the parts and are constituted by latching means
- the filter is mounted on the equipment (prior to placing parts 2 or not) by being fitted on a conduit 6 (for example that of a compressor of a generator) .
- the sleeve 110 of the filter (this sleeve extending from the upper flange as indicated above) is fitted with the air intake duct 6 of the equipment to which the filter is attached.
- a radial seal 61 is constituted by the inner wall of the sleeve 110 of the filter, providing a seal between the sleeve and the duct 6, this seal forming part of the filter flange and being molded in the same flexible material as the flange.
- Additional means of maintaining the filter may be provided, for example by bringing a bracket 5 fixed by one of its ends to the frame of the equipment on which the filter is mounted and the other of its ends to the rear flange 12 of the filter.
- the protective device can be removed without having to dismount the filter from the conduit.
- the protective device can be attached to the filter even if it is already mounted on the conduit. It is therefore possible to go from an unprotected configuration of the filter to a protected configuration without intervening on the mounting of the filter on the intake air duct.
