Abstract

The filter/trap, for use esp. in the agricultural and food industries, consists of a housing (A) which fits into an aperture in a ceiling, and an open-topped frame (B) with a cover (C). The frame (B) is shaped so that it overlaps the edge of the aperture, and the cover is detachable and equipped with two handles, allowing it to be removed from above to give access to the filters for cleaning. The housing (A) can be, e.g. cubic in shape with vertical filters, or in other shapes with the filters set at an angle.

Description

DESCRIPTION
La présente invention concerne des capteurs de buées principalement destinés à l'industrie agro-alimentaire.DESCRIPTION
The present invention relates to steam sensors mainly intended for the food industry.

Sur les appareils utilisés jusqu'ici l'accès et le démontage des éléments filtrants, s'effectuent par le dessous depuis le sol.On the devices used until now, the access and dismantling of the filter elements is carried out from below from the ground.

Lorsqu'il nL a pas de manutention mécanique au-dessus des appareils de cuisson, l'installation est classique à 2m ou 2,50m du sol avec un accès relativement aisé, comme dans les cuisines de restaurants. En industrie c'est un cas rare.When there is no mechanical handling above the cooking appliances, the installation is conventional at 2m or 2.50m from the ground with relatively easy access, as in restaurant kitchens. In industry this is a rare case.

Dans le cas contraire, avec palan de manutention, deux solutions restent possibles: a) Des capteurs traditionnels sont installés sous plafond, à une hauteur de l'ordre de
4,50m ou plus, avec une accessibilité incertaine voir dangeureuse pour l'entretien.Otherwise, with a handling hoist, two solutions remain possible: a) Traditional sensors are installed under the ceiling, at a height of the order of
4.50m or more, with uncertain or even dangerous accessibility for maintenance.

b) Des extractions directes en plafond sans filtration, avec pour conséquence des
dépôts gras dans les gaines, les extracteurs et sur les toitures. Les installations
souffrent, le nettoyage est malaisé et les développements bactériologiques
importants.b) Direct extraction from the ceiling without filtration, resulting in
fatty deposits in ducts, extractors and on roofs. The installations
suffer, cleaning is difficult and bacteriological developments
important.

Les nouveaux capteurs selon l'invention sont adaptés à l'utilisation industrielle et permettent de remédier à ces inconvénients. Le dessus est amovible, ils sont en effet prévus pour être accessibles par les combles techniques.The new sensors according to the invention are suitable for industrial use and make it possible to remedy these drawbacks. The top is removable, they are indeed intended to be accessible by the technical roof spaces.

Les dessins annexés illustrent l'invention
La planche 1 représente, en 1/2 coupe et 1/2 vue extérieure, le modèle cubique.The accompanying drawings illustrate the invention
Plate 1 represents, in 1/2 section and 1/2 exterior view, the cubic model.

La planche 2 représente le modèle central.Plate 2 represents the central model.

La planche 3 représente le modèle d'angle. Plate 3 represents the angle model.

En référence à ces dessins, I'appareil comporte un caisson porte-filtre (A) emboité dans la découpe du plafond. Ce caisson est équipé des éléments filtrants (D) au travers desquels l'air chargé de buées grasses sera aspiré. Le cadre supérieur (B) assure le maintien en venant en appui sur le plafond. Le couvercle (C) manoeuvrable par deux poignées, assure la fermeture de l'appareil. Ce couvercle comporte une ouverture centrale muni d'une bride de liaison afin d'être raccordé à l'extracteur monté en toiture.With reference to these drawings, the apparatus comprises a filter-holder box (A) fitted into the cut-out in the ceiling. This box is equipped with filter elements (D) through which the air charged with fatty mist will be sucked. The upper frame (B) provides support by coming to bear on the ceiling. The cover (C) operable by two handles, ensures the closing of the device. This cover has a central opening provided with a connecting flange so as to be connected to the roof mounted extractor.

Pour faciliter les opérations d'entretien cette liaison comportera une partie flexible pour la dépose aisé du couvercle.To facilitate maintenance operations, this connection will include a flexible part for easy removal of the cover.

Les éléments filtrants posés dans des glissières soit verticales, soit inclinées suivant les modèles, sont alors parfaitement accessibles pour être démontés et nettoyés. The filter elements placed in either vertical or inclined slides, depending on the model, are then perfectly accessible for dismantling and cleaning.
