Description

Programmable cabin for prewashing, washing, spraying, atomizing, rinsing, blowing, drying, for industry.

The present invention provides new and economical solutions in the field of washing operations, spraying, atomization, blowing rinse and drying of the parts or products to be treated.

The materials currently offered in these areas make it possible to carry out
one of the abovementioned operations in the cabin or in a tunnel, but not making it possible to carry out all of the programmed operations that the present invention performs.

The cabin is characterized by its cylindrical shape with vertical axis allowing self-cleaning, and avoiding any corner likely to facilitate the development of bacteria or molds.

They consist of a cylindrical shell Fig 1 Rep 1 closed at the top and bottom by circular caps Rep 2 and 3 and fitted with a door
Rep 4 placed inside or outside the cabin and rolling along it Fig 2 and 3, or opening on the outside like a conventional door mounted on hinges. Fig 4 Rep 5
The cabin can be mounted on feet with adjustable height Rep 6 to ensure leveling.

Seals can be placed between the door Rep 4 and the cabin Rep 1.

Depending on the applications, the cabin and the door can be made of ordinary or stainless steel, of any synthetic material depending on the products used.

The spray boom Fig 5 and 6 Rep 7 consists of a tube surrounding the parts or products to be treated Rep 8 and fitted with air or liquid projection nozzles Rep 9. The Rep boom 7 is guided by Rep sleeves 10 and moves on columns Rep 11 from top to bottom then from bottom to top.

During this movement, air or a pressurized liquid is sprayed on the products to be treated Rep 8
The movement of movement of the ramp Rep 7 can be obtained either by hydraulic or pneumatic jack, by any mechanical system for example a pinion and rack motor or by a motor pulley and cable assembly illustrated in FIG. 7 and 8 comprising - A drum Rep 12 driven by a geared motor group, with or without variator, placed on the same axis and not shown.

- Two Rep 13 cables winding on the Rep 12 drum and fixed on it.

- Two Rep 14 return pulleys - Two Rep 15 anchoring devices for the cable ends on the Rep 7 ramp
The prewash, washing and rinsing circuit is illustrated in Fig 9 and includes - A liquid tank Rep 16 - A suction pipe Rep 17 - A motor-pump group with variable flow or not, Rep 18 - A flexible pipe Rep 19 - The mobile Rep 7 ramp provided with its Rep 9 nozzles acting on the products to be treated Rep 8.

The circuits of: Prewash, wash, rinse, atomize, spray are identical, but may require different nozzle changes and liquids.

In some cases the atomization or spraying circuit may be fitted with a flow regulator
The blowing and drying circuits are based on the same principle, but in this case, it is air at room temperature or heated which circulates in the circuit Fig 10 comprising - 1 air filter Rep 20 - 1 possible device for reheating Rep 22 and 21 - 1 motor-fan or motor-booster group Rep 22 - 1 distributor Rep 23 for switching from the hydraulic circuit to the pneumatic circuit.

One of the novel applications of the invention consists in spraying a thin film of penicillium on cheeses during preparation.

To make the operation faster, and to ensure maximum use of the cabin, these Rep 24 cheeses can be placed on stackable shelves Rep 25 Fig 11 which can be placed on a Rep 26 trolley which is easy to enter or exit quickly from the cabin .

In the case of deposition of penicillium, the hydraulic circuit will preferably conform to that shown diagrammatically in FIG. 12 and will include the same elements as those of the diagram in FIG. 9 with in addition a flow regulator, adjustable or not Rep 27.

 Parallel to this circuit, pipes will bring to the nozzles - The air necessary for the atomization of the penicillium - The air pressure necessary for the control of the atomization nozzles.

This device is illustrated in FIG. 13 comprising - A penicillium distribution manifold Rep 28 - A penicillium inlet pipe Rep 29 - A penicillium return pipe Rep 30 - Rep 31 atomization nozzles - A manifold Rep 32 atomization air supply - A Rep 33 pilot air intake manifold - Rep 34 atomization air intake - Rep 35 pilot air intake
The elements described above, form a set which moves vertically from top to bottom and from bottom to top as in the case of the diagram
Fig 5
The problem of cleaning the cabin after atomization of penicillium is particular.

 I1 is illustrated in FIG. 14 and includes - At the top of the cabin, wash balls Rep 36 allowing projection under pressure of water added with cleaning products from all angles.

- A Rep 37 motor-pump group - A Rep 38 pipe connecting the Rep 36 balls to the motor-pump group
Rep 37
The water added with the detergent is poured into the bottom of the cabin then sprayed under pressure by the balls Rep 36 placed in the upper part.

Finally, the washing water is evacuated by gravity
The systems for washing or depositing products according to the diagrams in Fig. 5 and Fig. 12 can be applied for example to washing, treatment, decontamination of industrial parts, various surgical instruments, hospital equipment, food processing equipment. , horticultural ect ...

In order to improve productivity by grouping several cabins can be profitable.
This grouping is illustrated by FIGS 15 and 16 comprising - Rep 39 an entry door - Rep 40 an exit door - Rep 41 a set of 3 cabins - Rep 42 two intermediate doors - Rep 43 one or two opening devices and closing doors
intermediate - Rep 44 the parts or products to be worn, possibly placed on a shelf
tes et trolleys - Rep 45 a device for inking each trolley on the conveyor - Rep 46 a stepper conveyor of any type - Rep 47 a trolley waiting at the entrance - Rep 48 a trolley in progress evacuation
The different phases of the operations can be programmed, for example - Opening the doors - Introduction of a trolley to be treated - Advancing one step - Evacuation of a treated trolley - Closing of the doors - Movement of the ramps and projection of liquids example
Cabin n01 Prewash
Cabin n02 Washing
Cabin n03 Rinsing - Ramps and projections stop
The industrial manufacturing possibilities are immediate and do not require any specific tool or particular machine.

Only simple boilermaking, piping, hydraulic and pneumatic techniques are to be used.

Automation techniques are also known, whether pneumatic or electric.
