Definitions
- the invention relates to cleaning equipment for cleaning a tank for storing flammable products and delimiting an internal volume having an opening, this equipment comprising a shutter adapted to close the opening by isolating the internal volume of the tank a space external to the tank, a hose passing through a first orifice of the shutter, a carriage sized to be able to pass through the opening and to be selectively introduced into the internal volume of the tank, and a cleaning head carried by the carriage, connected to to the hose, and designed to spray a cleaning liquid delivered under high pressure by the hose.
- the degassing and cleaning operations of the tanks or storage tanks are carried out thanks to the intervention, inside the structure, of an operator previously introduced by the manhole and monitored. from the outside by another operator.
- the present invention aims to provide equipment free of at least one of these disadvantages.
- the equipment of the invention is essentially characterized in that it further comprises a rod connected to the carriage and passing through a second orifice of the shutter and in that the carriage comprises a frame with rolling members, the carriage can thus adopt, in the internal volume, a position controlled by an action exerted on the rod in the space outside the tank.
- the frame has a tubular structure comprising at least two bases spaced from each other and longitudinal members connecting the two bases, this structure surrounding a protected space, and the cleaning head being fixed to the frame and disposed in the housing. protected area.
- the cleaning head has several nozzles rotatably mounted around at least a first axis and driven in rotation, in operation, by the ejection of the cleaning liquid.
- the cleaning head may even include a stator and a rotor, the nozzles being rotatably mounted about the first axis on the rotor, and the rotor itself being rotatably mounted on the stator about a second axis not parallel to the first axis.
- the equipment of the invention may also comprise an extraction mouth, an extraction pipe, a gas analyzer and an air pump, the extraction mouth being mounted on the carriage and provided with a float, the extraction pipe passing through a third orifice of the shutter and connecting the extraction mouth to the analyzer and the air pump conveying to the analyzer air from the extraction mouth.
- the equipment can therefore include means for continuously analyzing the gases contained in the reservoir.
- the rolling members may comprise four or more wheels.
- At least one of the bases of the frame structure forms a lift polygon for the carriage.
- the ring is preferably made of an electrically conductive material, in particular a conductive polymer, and may be bonded to the cleaning head.
- FIG. 1 is a schematic side view of an equipment according to the invention.
- FIG. 2 is a view of a carriage belonging to this equipment and observed on the side of its anterior base.
- the main elements illustrated in these figures and invoked in the present description are identified by references in parentheses or not, references in parentheses being assigned to the sets to which belong to the elements identified by references without parentheses.
- the invention relates to cleaning equipment for cleaning a tank (not shown) for storing flammable products and delimiting an internal volume Vint, having an opening.
- This equipment comprises at least one shutter 1, a hose 2, a carriage 3, a cleaning head 4, and a rod 5.
- the shutter 1 is designed to close the opening so as to isolate the internal volume Vint of the tank from the external space to the tank, noted Ext.
- the carriage 3 is sized to be able to pass through the opening and thus to be introduced at will into the internal volume Vint of the tank from the space Ext.
- the cleaning head 4, which is carried by the carriage 3, is connected to a high-pressure pump 20 via the hose 2 which passes through an orifice 11 of the shutter 1.
- the cleaning head 4 is designed to spray a cleaning liquid pumped by the high pressure pump 20 and delivered to the head 2 by the hose 2.
- This head 4 typically comprises a stator 40, a rotor
- nozzle 400 and a plurality of nozzles 41, these nozzles being rotatably mounted about at least a first axis X and driven in rotation, in operation, by the ejection of the cleaning liquid.
- the nozzles 41 are rotatably mounted about the first axis X on the rotor 400, and the rotor 400 is itself rotatably mounted on the stator 40 about a second axis Y not parallel to the first axis X.
- the ring 5 is connected to the carriage 3 and passes through a second orifice 12 of the shutter 1.
- the carriage 3 comprises a frame 30 provided with rolling members 300, for example consisting of four or more wheels. Thanks to this arrangement, the carriage 3 can adopt, in the internal volume Vint, a position controlled by an action exerted on the rod 5 in the space Ext, external to the tank to be cleaned.
- the frame 30 has a tubular structure comprising two bases 31 and 32 spaced apart from one another, and longitudinal members 33, 34 and 35 interconnecting the two bases 31 and 32.
- the tubular structure of the frame 30 thus delimits a protected space Epr which it surrounds on all sides and inside which the cleaning head 4 is arranged.
- stator 40 of the head 4 is for example fixed to each of the longitudinal members 33, 34, and 35 of the frame 30, and the wheels 300 are mounted to freely rotate on the lower longitudinal members 34 and 35.
- the bases 31 and 32 of the chassis 30 are for example identical.
- the ring 5 which is advantageously made of an electrically conductive material such as a semi-rigid conductive polymer, is directly connected to the stator 40 of the cleaning head 4 to allow the outward flow Ext of the electrical charges which could accumulate on the cleaning head 4.
- the equipment of the invention further comprises an extraction mouth 61, an extraction pipe 62, a gas analyzer 63 and an air pump 64.
- the extraction mouth 61 is mounted on the carriage 3 and the extraction pipe 62, which passes through a third orifice 13 of the shutter 1, connects the extraction mouth 61 to the analyzer 63.
- This extraction mouth 61 is preferably provided with a float 610 to prevent the insertion of liquid into the extraction pipe 62.
- the air pump 64 conveys the air from the extraction port 61 to the analyzer 63, which can thus continuously monitor the gas concentrations in the tank to assess the risk of explosion.
- the equipment of the invention may also comprise a suction pump 72 disposed outside the tank and connected to the internal volume Vint of this tank by a suction pipe 71 passing through a fourth orifice 14 of the shutter 1 .
- the carriage 3 is made of materials chosen to minimize any risk of ignition or explosion, the frame 30 being for example made of stainless steel covered with a rubber coating, and the wheels 300 being made in one or more antistatic materials.
- the equipment of the invention may also include a camera embedded on the carriage 3 and allowing 1 inspection of the tank to be cleaned, and an ultrasonic detector to verify the integrity of the tank.
