According to the method, the said faeces are treated by cryogenic cooling with the aid of fluid which is closely confined spatially. The processing method and equipment can be applied to the recovery of dog faeces, in particular in an urban environment.

Description

"PROCEDE DE TRAITEMENT DE5 DEJECTIONS CANINES ET APPAREIL DE MISE EN
OEUVRF. "
La présent invention concerne un procédé de traitement de déjections canines, produits difficilement préhensibles en vue de leur récupération, et un matériel de traitement dP mise efl oeuvre de ce procédé."PROCESS FOR TREATING 5 CANINE DEJECTIONS AND APPARATUS FOR IMPLEMENTING
OEUVRF. "
The present invention relates to a process for the treatment of canine excrement, products which are difficult to grasp with a view to their recovery, and to a treatment equipment for the implementation of this process.

des produits, de consistance molle, présentent des difficultés d manipulation en vue de leur enlèvement et de leur récupération. En outre, cas produits peuvent polluer les plans ou surfaces sur lesquels ils sont déposés, et leur élimination intégrale est d'autant plus souhaitable. Toutefois, leur tendancP à l'étalement rend leur récupération malaisé.  products, of soft consistency, present difficulties of handling with a view to their removal and their recovery. In addition, cases produced can pollute the plans or surfaces on which they are deposited, and their complete elimination is all the more desirable. However, their tendency to spread makes their recovery difficult.

Indépendamment de la méthode d ramassage artisanale, on a proposé des systèmes munis de brosses tournantes éventuellement équipés de moyens d'aspiration. Toutefois, cette technique, dans de nombreux cas, provoque lecrasement du produit en laissant des salissures. Independently of the artisanal collection method, systems with rotating brushes have been proposed, possibly fitted with suction means. However, this technique, in many cases, causes the product to be crushed, leaving soil.

Aussi, en vue d'obtenir une depollution rapide, efficace sans les inconvénients des méthodes connues9 on a proposé un procédé de durcissement, en vue d faciliter la récupération des substances de consistance molle afin d'assurer la propreté des chaussées et trottoirs, notamment en milieu urbain, en particulier dans les gran- des cités où se pos un problème d'assainissement. Also, in order to obtain a rapid, effective depollution without the drawbacks of known methods9, a hardening process has been proposed, with a view to facilitating the recovery of substances of soft consistency in order to ensure the cleanliness of roads and sidewalks, in particular in urban environment, especially in large cities where there is a sanitation problem.

SPlon 1 nouveau procédé les déjections canines sont traitées par refroidissement cryogénique, à l'aide d'un fluide cryogénique étroItement confiné spatialement.  SPlon 1 new process canine excrement is treated by cryogenic cooling, using a cryogenic fluid tightly confined spatially.

Le fluide cryogénique est injecté à l'intérieur d'une enceinte recouvrant la déjection, ce qui permet d'obtenir un durcissemant pratiquement instantané, avec une consommation minimale en frigories; le débit du fluide cryogénique étant régulé de manier à exercer une action de refroidissement et durcissement très rapides. The cryogenic fluid is injected inside an enclosure covering the dejection, which makes it possible to obtain an almost instant hardening, with a minimum consumption of frigories; the flow rate of the cryogenic fluid being regulated so as to exert a very rapid cooling and hardening action.

On peut envisager l'utilisation satisfaisante de divers fluides cryogéniques tels l'anhydrido carbonique et l'azote liquide, ce dernier fluide étant préféré. One can envisage the satisfactory use of various cryogenic fluids such as carbon dioxide and liquid nitrogen, the latter fluid being preferred.

L'appareil permettant de mettre en oeuvre le procédé pré conisé se compose essentiellement d'un réservoir cryogénique et d'un dispositif d'injection du liquide cryogénique assurant le refroidissement de la substance à récupérer.  The apparatus making it possible to implement the pre-conized process essentially consists of a cryogenic tank and a device for injecting the cryogenic liquid ensuring the cooling of the substance to be recovered.

Le dispositif d'injection est raccordé au réservoir cryogénique isolé par l'intermédiaire d'une vanne; le dispositif se composant d'un flexible isolé, muni d'une poignée, d'une canne isolée terminée par une buse d'injection, et en outre d'une cloche de traitement fixée à ltextrémité de la canne. The injection device is connected to the isolated cryogenic tank via a valve; the device consisting of an insulated hose, provided with a handle, an insulated cane terminated by an injection nozzle, and in addition a treatment bell fixed to the end of the cane.

On peut envisager divers types de réservoirs de liquide cryogénique, les réservoirs portables représentent une réalisation particulièrement avantageuse pour l'opérateur, la mobilité et la souplesse de la mise en Oeuvre du procédé. We can consider various types of cryogenic liquid tanks, portable tanks represent a particularly advantageous embodiment for the operator, the mobility and flexibility of the implementation of the process.

Le réservoir de liquide cryogénique, isolé de manière connu, comporte à sa partie supérieure une tete permettant le remplissage, obturée par un bouchon de remplissage, équipée de moyens de sécurité, tels soupape, clapet de sécurité, clinquants. The cryogenic liquid tank, insulated in a known manner, has at its upper part a head for filling, closed by a filling plug, equipped with safety means, such as a valve, safety valve, foils.

A la partie inférieure, se situe une sortie isolée sous vide, terminée par une vanne quart de tour. Dans le cas d'un réservoir portable, il est muni de sangles permettant son positionnement sur le dos de l'opérateur.At the bottom, there is an isolated vacuum outlet, terminated by a quarter-turn valve. In the case of a portable tank, it is provided with straps allowing its positioning on the operator's back.

L'apparillage en coupe est représenté sur la figure 1 du dessin annexé, et le réservoir sur la figure 2. The apparatus in section is shown in FIG. 1 of the appended drawing, and the tank in FIG. 2.

Le réservoir de fluide cryogénique (1) avec isolation (2 d'une capacité de 10 litres environ, pour un réservoir dorsal, est équipé à sa partie supérieure d'une tette (3) de remplissage munie d'un bouchon de remplissage (4) avec clapet de sécurité (5), à sa partie inférieure de la sortie isolée sous vide (6), terminée par la vanne 1/4 tour (7) commandée par le levier (8). The cryogenic fluid tank (1) with insulation (2 with a capacity of approximately 10 liters, for a back tank, is equipped at its upper part with a filler cap (3) provided with a filler cap (4 ) with safety valve (5), at its lower part of the vacuum-insulated outlet (6), terminated by the 1/4 turn valve (7) controlled by the lever (8).

Le dispositif d'injection raccordé à la vanne (7) se compose du flexible calorifugé (9) muni d'une poignée (10), de la canne isolée (11) terminée par la buse d'injection (2) et de la cloche de traitement (13) fixé à l'extrémité de la canne calorifugée. The injection device connected to the valve (7) consists of the insulated hose (9) provided with a handle (10), the insulated rod (11) terminated by the injection nozzle (2) and the bell treatment (13) fixed to the end of the insulated rod.

Le poids de l'ensemble de l'appareil avec réservoir rempli d'azote liquide ne dépasse pas 15 kgs. The weight of the whole device with tank filled with liquid nitrogen does not exceed 15 kgs.

Le procédé de traitement par cryogénisation de déjections canines en vue d leur récupération est applicable n particulier sur les voies des centres urbains.  The process of cryogenic treatment of dog excrement with a view to their recovery is applicable in particular on the roads of urban centers.
