Claims priority, application France October 27, 1954 2 Claims. (Cl. 137-563) The present invention relates to a pump for autoclaves for the humid treatment of masses of textile bers.
Apparatus is known for the humid treatment of textile or other material which apparatus comprises devices for feeding the products to be tinted into the autoclaves under pressure which apparatus, however, does not permit such continued and regular feeding. It requires a source of outside pressure and does not provide for the continued removal of the gases formed in the autoclave.
In effect itis necessary to remove particularly the gases formed in the autoclave. Furthermore, it is of advantage to provide the possibility of feeding the products to be tinted or others into the treament bath, to provide a circulation across the material to be treated without stopping the operation of the apparatus and without providing an exterior pressure source, even if the housing of the autoclave is under higher pressure than atmospheric pressure.
It is also of advantage to provide the possibility of creation of a basic pressure in the autoclave which is higher than the strongest circulation pressure, in such manner that at no time and at no point in the apparatus a depression can arise. This arrangement avoids the possibility of entrance of air or of a complete evaporation which could lead to a sub-pressure in the pump or to accidental tinting.
It is, therefore, one object of the present invention to provide a pump which permits of arrangement of an auxiliary circulation of reduced output starting from the highest portion of the autoclave to pass to a container which can be completely closed and sealed and in which the coloring material may be introduced in such manner that the auxiliary output is taken up by the pump to be returned into the principal bath circulation across the material. It is believed that the evacuation of the formed gases takes place automatically from the highest portion of the autoclave toward said container and that the pump also creates the basic pressure in the housing of the autoclave. The arrangement of the auxiliary circulation is clearly disclosed in the French Patent No. 1,054,941, dated February 28, 1952.
It is another object of the present invention to provide a pump for autoclaves for the humid treatment of masses of textile bers which comprises a turbine consisting of helicoidal blades adapted to create the bath circulation across the material to be treated to be rotated in one or the other direction and of centrifugal blades adapted to create in the housing of the autoclave the basic pressure and the auxiliary circulation pressure, always in the same direction whatever the direction of rotation of the turbine may be and consequently will be the direction of the bath circulation across the material.
With these and other objects in view which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:
Figure l is a side elevation, partly in section ofthe turbine perpendicular to the axis of rotation of said turbine;
Fig. 2 is an axial section of the turbine; and
Fig. 3 indicates schematically the entire assembly.
ICC
Referring now to the drawings, and in particular to Figs. 1 and 2, the turbine 1 comprises helicoidal blades 2, four of which are shown by example in the drawing, which blades 2 are disposed on a cylinder 3 which is integrally formed with a central member 4, and centrifugal blades 5, four of which are shown by example in the drawing, which are disposed on the face of the central member 4 opposite the supporting shaft 6.
The shaft 6 is mounted in a bearing 7 having packings 8.
The turbine lis mounted to turn in a cylinder 9 which is disposed between two snails 10 and 11. A tube 12 is disposed across the central portion of the centrifugal blades 5.
The pump operates in the following manner:
The output of the helicoidal part of the turbine is the principal output which passes across the material to be treated. The tube 10a of the snail 10 is in communication with the housing 13 of the autoclave surrounding the material 14 to be treated. The tube 11,J of the snail 11 is in communication with the internal portion of the material 14 to be treated. The centrifugal blades 5 create a suction etfect in the tube 12 `which is transferred by means of the tube 15, which is equipped with a valve 16 to the closed and sealed container 17. This container 17 has at its upper portion an opening 18 closed by a liquid tight cover of any conventional structure in order to introduce therethrough tinting or other products and finally has also a removable valve 19. lt is equipped in its interior with a cooling coil 20 and a pipe 21 of narrow cross section in communtication with the container 17 at one end and with the upper portion of the autoclave 13 at its other end. This pipe 21 has a control Valve 22 and a device 23 adapted to limit the output at a predetermined value, which device 23 may be, for instance, a diaphragm of predetermined setting. The centrifugal blades 5 suppress in the autoclave the auxiliary circulation by means of the snail 10, which auxiliary circulation is set up by the tubes of narrow cross section 15 and 21 across the closed and sealed container 17. The output in the circulation is controlled by the calibrated diaphragm 23 and its control may be complemented by a valve 22. This tube of narrow cross section permits the control of the basic pressure created by the centrifugal blades 5.
The gases which may possibly be formed in the autoclave are immediately evacuated through the tube 21 and remain in the upper portion of the container 17 wherefrom they do not return. In order to introduce tinting or other products into the autoclave during the operation of the apparatus, it suffices to close the valves 16 and 22 to cool the liquid in the container 17 if vapor pressure is present or to reduce the pressure by means of the valve 19. It is possible to introduce the products through the opening 18 in the container 17 and upon closing again said opening 18, the container 17 is put again into the circuit by opening the valves 16 and 22.
The introduction of the products is thus possible regularly into the principal circulation of the pump, said introduction of the products being controllable by the auxiliary circulation passing through the container 17.
If the pump operates in the direction indicated by the arrows a (Fig. 1), the centrifugal blades 5 operate into the snail 10 and create the basic pressure in the autoclave. The helicoidal blades 2 operate into the snail 11 and create in the interior of the material to be treated a pressure equal with that in the autoclave provided by the centrifugal blades 5 increased by the loss due to the bath circulation in the material.
If the pump operates in the direction indicated by the arrows b (Fig. l), the centrifugal blades 5 operate always into the snail 10 and create the same basic pressure in the rst Wheel, creating ,pressure in autoclave, while ,they heliooiclalg blades A2 ncreate a suction effect in the Snail 11 in Snehmenner that thepressnrein the interior of the material, transferred from 11a to 11, is equal to the basic pressure in the autoclave, reduced however .by the loss to y the v`bath ,circulation across the material.
