Definitions
- the invention relates to a rotary vane vacuum pump which is particularly suitable for use in industry in which it is necessary to observe certain hygiene rules both during operation of the pump and with regard to the cleaning services.
- Rotary vane vacuum pumps have been around for a long time.
- the rotor is provided with several blades (called “pallets”) which slide radially and which ensure the transfer of the pumped air.
- the major object of the invention is therefore to propose a rotary vane vacuum pump which does not have the abovementioned disadvantages and which is particularly suitable for use in environments subject to strict hygiene standards.
- a rotary vane vacuum pump which has the particularity that all the surfaces of the pump visible from the top are arranged in such a way that they are free of elements capable of holding liquids or solids.
- this pump may, at least in one part, be provided with protective means without surfaces or recesses capable of retaining liquids or solids.
- Such a pump has the further advantage of being easy to clean. It is therefore very suitable for uses in industries in which it is necessary to comply with certain hygiene rules.
- FIG. 1 a rotary vane vacuum pump according to the prior art to the invention
- FIGS. 3, 4 and 5 are front, back and front perspective views after clockwise pivoting of a pump according to a second embodiment of the invention
- FIGS. 6, 7 and 8 are views respectively corresponding to those of FIGS. 3, 4 and 5, of the pump according to the second embodiment, equipped with an oil mist separator. Detailed exposition of the invention
- the rotary vane vacuum pump according to the invention is characterized in that all its visible surfaces from the top are arranged so that they are devoid of elements capable of retaining liquids or solids. Such surfaces, which are necessarily external, may be formed by cooling fins and they are located on the upper half of the vacuum pump, since the surfaces on the lower half of the vacuum pump can not because of gravity, hold back a liquid or a solid.
- the adjectives "upper” and “lower” used in this text (and this both in the description and in the claims) refer to the normal position of the pump when it is in functioning or ready to operate.
- the pump may also, at least in one part, be provided with means for protecting the upper surface.
- These means of protection must also be devoid of recesses, for example grooves, located on the upper half of the vacuum pump and inside which liquids or solids could stagnate.
- FIG. 1 shows a rotary vane vacuum pump according to the prior art.
- This pump comprises in particular a drive motor, in this case an asynchronous motor which is cooled in air.
- This motor is coupled to a pumping chamber 2, in order to drive the rotor of the latter in rotation, so that the pump can perform its pumping function.
- An intermediate cylinder V2 connects the drive motor to the pump chamber 2 and normally contains the connection elements between the drive motor and the pump chamber 2.
- This pumping chamber 2 is known per se, it generally comprises a rotor which is housed in a cylindrical bore and which carries pallets.
- the pumping chamber 2 can be supplied with oil, that is to say that an oil circulation system is then provided to lubricate, seal and allow the exchange of heat.
- This oil is separated from the pumped gases in an oil mist separator (not shown in the figure), so that the air leaving the outlet 3 can be removed from the oil that it contains before to be pushed back into the atmosphere.
- the pumping chamber 2 is also connected to a heat exchanger V1 with an integrated fan (not shown) which serves to cool the pumping chamber 2 which heats up during operation of the pump.
- the drive motor 1 and the pumping chamber 2 are preferably connected in a removable manner, which makes it possible to replace one or the other in case of failure.
- the pumping chamber 2 and the drive motor 1 have on their periphery cooling fins 5. These fins are the main characteristics of this pump. according to the prior art can not be suitable for use in a field requiring compliance with certain hygiene rules and ease of cleaning on site, as as explained above the fins can retain liquids or solids.
- the upper surface of a portion of the pump (including the portion of the pumping chamber 2) comprises only the smooth surfaces. These surfaces therefore do not include elements likely to retain liquids or solids so as to allow a natural flow of any liquid or natural slip of any solid that could fall on the pump.
- Figure 2 shows at the same time the other possibility to achieve the distinctive feature of the present invention, so the protective means 6 which are similar to a hood, that is to say they have substantially the shape of a half-cylinder covering in this case the upper part of the drive motor 1.
- the protection means 6 would be positioned in another part of the pump, e.g. ex. on the pumping chamber 2.
- the half-cylinder 6 covers only the upper fins 5 of the drive motor, the lower fins 16 then appearing in the lower part of the drive motor 1.
- the half-cylinder 6 is removable, which has the advantage that it is easily possible to access the drive motor 1 in the case of control and thorough cleaning.
- Examples of upper surfaces are those designated in FIG. 2 by reference numerals 8, 9, 10 and 11 for the pump chamber 2 and reference numerals 12 and 15 for the drive motor 1 .
- the inclination of the surfaces concerned is preferably at least 5 degrees relative to the ground, when the supports 13 and 14 rest on the ground.
- the oil mist separator comprises a common support block to the filter and the heat exchanger for the oil which makes it compact, accessible and easily cleaned.
- the rotary vane vacuum pump comprises a pumping chamber 2 which can be like that of Figures 1 and 2 and which is connected to a drive motor 17.
- the latter has the particularity to comprise a double jacket having an outer portion formed of a cylinder 18, visible in Figure 3, all or almost all of which is smooth on the outside.
- the inner part of this jacket which is in fact the motor housing not visible in FIG. 3, contains, in known manner, the usual components of a rotary vane vacuum pump motor, which may be an asynchronous motor.
- the outer surface of the cylinder 18 is smooth, unlike the first embodiment where the outer surface (see Figure 2) is generally provided with fins 16 cooling.
- the cylinder 18 is spaced from the casing (smooth or not) so as to form a space in which a cooling fluid such as a liquid, in particular water, can circulate, entering and leaving through the orifices 19 and 20 .
- a cooling fluid such as a liquid, in particular water
- the advantage of cooling with water is that it allows the extraction of the heat generated by the drive motor 17, without having recourse to the fins 16 (of FIG. 2), the surface of which makes it possible to exchange of heat with the air.
- the cylinder 18 is blind, that is to say closed at its free end, which facilitates the cleaning of the pump.
- the cylinder 18 is not removable because it is attached to the casing of the drive motor 17.
- the cylinder 18 is also removable.
- this separator comprises a block -support common to the filter and the heat exchanger for the oil 25, which makes it compact, accessible and easily cleaned.
