FR3056415B1 - DEVICE FOR CLEANING A NARROW SPACE - Google Patents

Abstract

The invention relates to a device for cleaning completely reduced spaces by coupling the passage of a fluid and the friction of a plate on these walls. It consists of an ergonomic handle equipped, on one side, a variator of flow and pressure of a fluid and nozzles of fluid passage located at the end of lances, positioned in front of a friction plate. The device according to the invention is particularly intended for the complete cleaning of the cells of air exchangers used in breeding Hors-sol.

Description

The present invention relates to a device for cleaning a reduced space (eg air-exchanger cells in above-ground farming) by the passage of a fluid at low or high pressure from a cleaner lance and by friction against its walls, an integrated plate.

Currently when cleaning a narrow space such as air exchanger cells (or air recyclers), no high or low pressure lance is provided to work without visibility while ensuring complete cleanliness of the walls. Some of these machines are removable so they can be put in soaking and be cleaned a little better but never fully and others not removable which makes them almost untangling in depth. The cells of these recyclers or air exchangers clog up with dust that sticks to the walls due to the condensation created by the temperature difference between incoming and outgoing outside air coming from inside the building. The invention will solve this cleaning quality problem thanks, on the one hand, to its variable dimensions adapted to that of these heat exchangers and the coupling of the passage of a variable pressure fluid and a rubbing plate on the walls. .

The annexes illustrate the invention

Fig1: detailed diagram of the device - annex 1/2

Fig2: view of the prototype - appendix 2/2

With reference to these appendices (diagram and view), the invention consists of an ergonomic handle (1) equipped with a system (8) for adjusting the pressure and the flow rate of a fluid on one side and lances ( 2) provided with nozzles (4) for the passage of a fluid and a plate (5) of friction of the other.

The device actuated at low pressure start (6) (for soaking (4) (7) in the case of a hydraulic fluid and avoiding the possible deterioration due to the high pressure) is returned to the reduced space then, by increasing the pressure and / or flow rate (6) (8) if necessary, the back and forth movement of the device, whether manual or automated, allows complete cleaning thanks to the effect of stripping of the fluid and the detachment of the dirt by friction of the integrated plate (5). In order to prevent the device from folding, it is stiffened by stiffeners (3) positioned along the lances (2).

The number of lances (2) and the dimensions of the nozzles (4) are studied and elaborated according to the fluid flow and pressure.

Too many sprays (2) decrease the power of the fluid thus reducing the effectiveness of the device

A too large diameter of the nozzles (4) decreases the power of the fluid thus reducing the effectiveness of the device

The flow / pressure ratio is essential for the efficiency and speed of cleaning

The device is provided with:

- Ergonomic handle

- Low and high pressure lances of number, length, diameter and variable manufacturing material, in which the passage of the fluid is made.

- Stiffeners in variable material, to reduce the risk of folding during use or during transport.

- Washing nozzle with variable dimensions depending on the flow rate and fluid pressure.

- Removable plate of dimensions, material and coating variable according to the area to be cleaned, which has a mechanical action by friction on the surfaces to be cleaned.

- Handle for adjusting the pressure and flow of the fluid used.

- Excess fluid outlet orifice during flow variation (this surplus facilitates the wetting / soaking and rinsing of the cleaned areas)

- Inverter device for flow and pressure of the fluid used

- Spray connection connection (or other cleaning fluid supply on / off system)

- Fixing system of the removable plate described in 5

As a non-limiting indication, the dimensions of the cleaning device will be between the ergonomic handle (l) and the nozzles (4) of 750mm with a plate length of 170 mm (dimension of the fastening system (10))
