FR2527106A1 - Insulated industrial washing machine - has two screens intended to reduce energy consumption by giving extra sealing - Google Patents

Abstract

The washing machine has a parallelepipedal frame with an internal isolating tank (2) for holding the heated cleaning fluid. Internal conveyors (4) carry out a cycle to permit precise washing and there is an isolating cover (1) to collect vapours in the equipment placed over the tank. Using condensation, the vapours are re-used and there are two screens (6,7), adjustable in both directions, to give maximum sealing at the level of vapour loss at the entry and outlet. The conveyor has side covers (5), fixed to it or not, to retain heat.

Description

The present invention relates to a device for an autonomous industrial washing machine with double airlock for cleaning and degreasing industrial parts made of ferrous metal or not.

More specifically, it is a device which makes it possible to clean parts which are machined or not in said double-lock washing machine.

The cleaning and degreasing of industrial parts requires meticulous work and the hourly cost and the energy cost which enter into the cost price must not be neglected.

We know classic machines that can perform this type of operation.

These consist of a sheet metal tunnel through which a carpet passes, where a plurality of pieces are placed on it. The piece is placed at the entrance to the gate, makes its circuit. The vapors and mists are evacuated by a chimney.

We realized however that there was a solution to bring to the level of the energy expenditure which was used to degrease and wash these parts.

The percentage of this energy, which leaves in the chimney, can be recovered by reinforcing the insulation of the machine, on the one hand, and on the other hand by modifying the input-output circuit by also removing the chimney.

The present invention intends to remedy these various drawbacks by proposing an improvement to known machines. In fact, the resulting economic conditions are significantly improved.

To this end, the invention relates to a device specially adapted for an industrial washing machine and which saves energy.

Generally, the machine is dressed by a t81é assembly, heated inside, which allows the sprayed liquid to clean said parts which are placed on a carpet and which circulate inside this airtight tank and bell .

According to one of the main characteristics of the invention, it is that the parts which are deposited on the special mat pass through a sealed airlock whose shape is studied according to the parts.

In a preferred embodiment of the invention, the parts are not at any point in their cycle in contact with the outside ambient air, although it is supplied continuously or in any other mode.

The originality of this device is to remove the unsightly chimney and always subject to problems with the environment by the deterioration of the roofs, pollution, etc ...

In this closed cycle system, the vapors discharged to the outside are almost non-existent (at most the volume of the compartment), therefore a concern for comfort has been brought by the manufacturer concerned with the health problems caused by bath vapors with a high alkaline or acidic detergent content, when they are sprayed in workshops where human contact is solid with the machine. On the other hand, the cost of installation in civil engineering is greatly reduced.

Finally and advantageously, the energy savings brought by this washing device makes it possible to recover 70% of the calories that are usually rejected or evacuated outside by their own chimney, which corresponds to an effective saving of 50%. installed power. This device is therefore appreciable in terms of the energy savings that companies can achieve by using this type of machine.

The invention will be better understood during the description described below by way of purely indicative and non-limiting example, yes allows @ ra to identify the advantages and the secondary characteristics thereof.

 Reference will be made to the accompanying drawings in which: - Figure I illustrates in a longitudinal section view along a line "w;" schematically the device for industrial washing machine @ doucle sas to save installed energy.

- Figure II is a top view of the washing machine - Figure III is a transverse view along arrow @.

 n referring first to Figure I there is a sectioned structure of a hooded and insulated assembly 1, 2, 6 and 7. This is divided into several parts, in this case, a washing compartment and a compartment draining, all in closed circuit, therefore without chimney. A heat-insulated tank 2 where the liquid is brought to temperature, the latter is equipped with a draining system 3 thus allowing the product to become liquid again after having undergone its thermodynamic cycle.

'Jn carpet system 4 specially designed to wash and clean the parts. Bais the originality of the carpet, it is that it is provided with special articulated partitions to allow him to place special baskets there which can replace the partitions while being hermetic, at the time of its entry between the airlock adjustable compared to the partition 6 and the exit hatch adjustable with respect to partition 7, which makes it possible to conserve the calories during the washing cycle.

A series of condenser-dryers, coolers e, 9, 10, are provided upon leaving the parts. The pieces will be collected by a container 11 or either to another conveyor belt.

Bulk and continuous feeding is done using a loading tray 12 or any other system fitted with a safety device 13.

the assembly is enclosed in a rigid chassis 14.

Figure II illustrates the electric or other heating mode 15, for this type of washing machine equipped with a pump 16, or filter 17. Figure 11 illustrates the usefulness of the insulated inspection doors 18.

The cleaning doors 19, also insulated to target all the green calories. In this case, all the elements listed above are inseparable if we want to optimize energy efficiency by reducing the various thermal bridges.

 It can be seen that with this device according to the invention, relatively low maintenance costs can be achieved while having the same final result in terms of washing and stripping of the parts. Note that we can see in Figure TII the device of the tank designed to receive the different types of elements, such as filters, built-in purification system and other conventional elements but necessary for its full operation .

The invention finds an interesting application in cleaning, degreasing, washing of parts, linked to different industries: automobiles, aeronautics, Food processing, Communities and others.

 The island is not limited to the description which comes from other data, but on the contrary incubates all the variants which could be made to it without departing from its framework or its spirit.
