Description

Title of the invention: CLEANING STATION AND USE

[0001] The invention relates to a cleaning station, in particular for metal parts, as well as its use. Background of the invention

[0002] European patent application No. EP 0 187 174 published in 1984 describes a mobile installation for cleaning portable receptacles such as waste baskets.

[0003] However, there is currently no simple and easy-to-use solution for cleaning larger metal parts with recovery of cleaning water. Currently, these effluents are discharged into the sewers, which can cause treatment problems at the treatment plants or in nature, which can lead to soil pollution. Summary of the invention

[0004] The main aim of the invention is to propose a cleaning station which is capable of facilitating the cleaning and / or washing of parts, particularly metal parts, in a simple manner and without causing any problems of effluent treatment or pollution.

[0005] According to the invention, this aim is achieved using a cleaning station in accordance with the following statement: 1. Cleaning station including: - a perforated floor, - at least one vertical wall rising from the perforated floor, - a horizontal wall located at the top of the vertical wall, - one side open, - a recovery bin located under the perforated floor, - a suction pipe having an inlet connected to the recovery tank and an outlet, - a discharge pipe having an inlet and an outlet, - a pump placed between the outlet of the suction pipe and the inlet of the pipe of repression and - at least one container connected to the outlet of the discharge pipe.

[0006] Advantageous features of the cleaning station of the aforementioned statement 1 are indicated in the following statements 2 to 7: 1. Cleaning station according to statement 1, in which the collection tray operation is inclined and the suction pipe inlet is connected to a lower part of the collection tank. 2. Cleaning station according to statement 2, in which the angle of inclination of the collection tank is approximately 0.5 degrees. 3. Cleaning station according to one of the preceding statements, further comprising at least one valve arranged between the outlet of the discharge pipe, the container(s) and a drain pipe. 4. Cleaning station according to one of the preceding statements, further comprising a shower. 5. Cleaning station according to statement 5, comprising a shower water collection tank connected to a drain pipe. 6. Cleaning station according to one of the preceding statements, equipped with wheels.

[0007] According to another aspect, the invention also relates to the use according to the following statement 8: 1. Use of a station according to one of the preceding statements for washing or cleaning a part, in particular a metal part, in which this part is arranged in the station and a user stands facing the open side (6) of the station and sprays at least one liquid onto it.

[0008] Advantageous features of the use of the aforementioned statement 8 are indicated in the following statements 9 and 10: 1. Use according to the preceding statement, in which the spraying aims to carry out one or more of the following operations:

[0009] - degreasing

[0010] - stripping and

[0011] - a passivation. 1. Use according to statement 9, in which the user changes the container after each operation.

[0012] Other characteristics and advantages of the invention will now be described in detail in the following description which is given with reference to the appended figures, which schematically represent:

[0013] [Fig-1]: a front view of a cleaning station according to the invention;

[0014] [Fig.2]: a rear view of the station of [Fig.l];

[0015] [Fig.3]: a right-hand view of the station of figures 1 and 2;

[0016] [Fig.4]: a left view of the station of figures 1 to 3; and

[0017] [Fig.5]: a top view of the station of figures 1 to 4. Detailed description of the invention Cleaning station

[0018] In [Fig.l] an example of a cleaning station according to the invention is shown.

[0019] This cleaning station includes: - a perforated floor 1 intended to be crossed by washing / cleaning liquids, - a rear vertical wall 2 and two side vertical walls 3,4 rising from the perforated floor 1, - a horizontal wall 5 located above the vertical walls 2, 3, 4 and serving as a roof for the cleaning station, - at the front, that is to say opposite the rear vertical wall 2, an open side 6, in order to allow a user to place parts, in particular metal parts, in the station, then to spray at least one cleaning or washing liquid on them.

[0020] In order to prevent the effluents from reaching the ground and polluting it, a recovery tank 7 is fixed under the perforated floor 1. The liquids falling from the rooms and collected in the recovery tank 7 can be sucked up through a suction pipe whose inlet is connected to the recovery tank 7 and the outlet to a pump 8.

[0021] The liquids are then sent by the pump 8 into a discharge pipe on which several valves are provided, the outlets of which are connected to collection containers 9 to 14 arranged behind the rear vertical wall 2 and better visible in [Fig.2],

[0022] These valves make it possible to select one or more containers from among the containers 9 to 14. Each container can thus collect only the liquid coming from a specific washing or cleaning operation.

[0023] Preferably, in order to facilitate the evacuation of liquids, the recovery tank 7 is inclined and the suction pipe is connected to its lower part.

[0024] The angle of inclination may be, for example, approximately 0.5 degrees.

[0025] Similarly, the roof 5 is also preferably inclined, generally towards the rear, in order to facilitate the flow of rainwater, or even snow.

[0026] The floor 1 is preferably made of a tubular stainless steel frame.

[0027] The recovery tank 7 can also be made of stainless steel, in order to resist the corrosion due to chemicals that may be used during cleaning.

[0028] The vertical walls, rear 2 and side 3,4, serve to protect the environment from liquid splashes, they must therefore also be resistant to chemicals and are for example made of stainless steel.

[0029] Suction and discharge pipes, valves and parts of the pump that come into contact with chemicals must also be made of chemical-resistant materials, such as stainless steel.

[0030] Each container is normally designed to withstand at least the chemical product it is to receive.

[0031] A filtration grid is preferably provided at the inlet of the suction pipe to stop any solid matter.

[0032] The discharge pipe can be connected, downstream of the valves, to a sewer, for the discharge of effluents not requiring recovery or treatment.

[0033] According to a preferred embodiment of the invention, a safety shower is provided in the event that the user of the station has received splashes of potentially dangerous chemical products.

[0034] A shower head 15 is positioned high up and connected to a water inlet pipe of the public water distribution network via a tap. A shower tray may be provided to collect the shower water and return it to the sewer pipe or possibly to the containers via the aforementioned discharge pipe and a suitable small pump.

[0035] The cleaning station according to the invention is preferably designed to be outside a building and, according to an advantageous embodiment of the invention, it is mobile. For this, the floor 1 is mounted on a support which is preferably provided with wheels. Thanks to this, the cleaning station acquires mobility and can be moved, for example from a location next to a hangar to another location near another hangar, as required. Using the cleaning station

[0036] To use the cleaning station according to the invention, a user must place the parts to be cleaned on the floor 1, accessing them via the open side 6 of the station. Then, preferably after having put on a protective suit, he positions himself opposite the open side 7 and sprays a liquid onto the part using a suitable liquid projection lance.

[0037] It can then change liquid in order to carry out one or more other operation(s) such as:

[0038] - degreasing

[0039] - a stripping and

[0040] - a passivation.

[0041] The pump is preferably started by means of an electrical control box shortly after the start of the first spraying in order to avoid mixing of the dirty sprayed liquids. At each change of liquid, the user closes the open valve and opens the valve corresponding to the next liquid to be sprayed and recovered dirty. However, the liquids can also be mixed, everything depends on the recommendations of their manufacturers.
