The present invention relates to a device for drawing in and pumping out a fluid medium, which has a casing (1). A shaft (3), a rotor (2) and a partition plate (5) are arranged in the casing (1). A plurality of circular disks (4) are fixed on the shaft. The partition plate is fixed on the wall of the casing (1) along the center line of the shaft (3) to form a drawing in region (6) and an extruding out region (7). According to the present invention, the circumference wall of the casing (1) forms a communicated groove in which an auxiliary partition plate (8) is fixed on the same wall of the casing (1) along the center line of the shaft (3) to form an auxiliary drawing in region (9) and an auxiliary extruding out region (10). The two partition plates (5 and 8) are respectively arranged on opposite both ends relatively to the rotor (2).

Description

Device for drawing-in and pumping-out fluid medium

The present invention relates to the structure of pump structure and ventilator, relate to the device for drawing-in and pumping-out of flowing medium more specifically.

Such device is used for the exchange of air in the ventilation regulating system of daily life and industrial building and facility and in the building, and can be used as convection current that pump is used for liquid equally and draw and send.

On record flowing medium device for drawing-in and pumping-out, a folded formula is housed in its housing with the concentric rotor of fixed disc and one be fixed on the wall and constitute the dividing plate (US, A, 3275223) that sinks the district and extrude the district.

In this device, the part of shell body wall is cylindrical.Utilize the interior toughness frictional force of disc surfaces interface layer of revolvable rotor that medium is gone out the district from sinking district's pump entrance pressure.MEDIA FLOW enters and sinks the district, and is mobile along the internal surface of housing cylindrical wall, simultaneously in fact the direction that flows changed by 180 °, then through extruding district's outflow.In the case, the part of medium is to enter to sink the district from extruding the district through the gap overflow between the disk of that end of dividing plate, and the direction along rotor rotation flows again then.Owing to will make media flow direction in the housing change the friction when the device cylinder is opened part and flowed of 180 °, medium high speed flow, and medium from extrude the district through the gap overflow between the disk of that end of dividing plate to sinking the district, the energy loss that is consumed is quite big; Therefore said apparatus does not have high throughput and high efficient.

Another kind of well-known flowing medium device for drawing-in and pumping-out, in its housing, be equipped with one and comprise that the rotor that is fixed with a plurality of disks on one is fixed on the relative wall in the housing and with this along the shaft centre line orientation and constitutes the dividing plate (SU that sinks the district and extrude the district with one, A, 985444).In this device, the part of shell body wall is cylindrical, and the dividing plate of that end of disk has been made pectination shape, and the pectination part is arranged between the disk.Wait to draw the medium that send and change the extrusion chamber over to from sinking the chamber by the viscous friction in the revolvable rotor discs surface interface layer.Medium flows to and sinks the district, and is mobile along the internal surface of housing cylindrical wall, and flow direction is changed in the opposite direction, so just flows out through extruding the chamber.The dividing plate of making pectination can prevent that medium from flowing into the energy loss that the extrusion district is consumed from sinking the district; Still exist but make medium change the energy loss situations that direction consumed by 180 ° in housing, medium is consumed in friction along column part with flow at high speed energy loss is no change also.Therefore, the structure of this device can not improve throughput and efficient in fact.

As the task on basis of the present invention is to build a kind of its shell construction to realize that under high productive capacity and high efficiency condition the flowing medium convection current draws the device that send.

The approach of finishing of this task is: in the flowing medium device for drawing-in and pumping-out, in its housing, be equipped with one comprise the rotor of fixing a plurality of disks on the axle and center line along axle be fixed on the shell body wall and constitute the dividing plate that sinks the district and extrude the district with this, according to the present invention, the perisporium of housing constitutes the groove of a perforation, adorn an accessory septa therein, this dividing plate also is that the center line along axle is fixed on the identical wall of housing, and constitutes with this and auxiliaryly to sink Qu Hefu and to extrude the district.In the case, two dividing plates are arranged in relative two ends with respect to rotor.

The through slot structure of flowing medium device for drawing-in and pumping-out housing, accessory septa configuration and two dividing plates liquid stream that can constitute two bursts of convection current with respect to rotor in the layout of opposite end therein.In the case, every dividing plate will sink the district and separate into two-part with extrusion, reduce energy loss and eliminating and the relevant energy loss of change flowing medium moving direction that liquid stream is caused along the shell body wall flowage friction therefrom.So just, can improve throughput and efficient significantly.

Below, by the object lesson of apparatus structure and the detailed description of quoting the caption of being advised are illustrated the present invention.According to the present invention, in the figure of this suggestion, expression be always to scheme along the cross section of rotor centerline.

The flowing medium device for drawing-in and pumping-out of applying for a patent power has housing 1, and rotor 2 is housed in housing 1, and rotor 2 has an axle 3 that is fixed with a plurality of disks 4 thereon.Fixing a dividing plate 5 constitutes with this and sinks district 6 and extrude district 7 along the center line orientation of axle 3 in the inwall upper edge of housing 1.According to the present invention, the inner circle wall of housing 1 forms a through slot; An accessory septa 8 is housed in this groove.Accessory septa 8 also is to be fixed on the same inwall of housing 1 along the center line orientation of axle 3, constitutes auxiliary district 9 and the auxiliary district 10 that extrudes of sinking with this.Two dividing plates 5 are arranged in relative two ends with 8 with respect to rotor 2.

The flowing medium device for drawing-in and pumping-out is in the following manner:

When containing an axle rotor 2 of 3 that is fixed with a plurality of disks 4 thereon by the direction rotation of arrow A indication, treating in the device case 1 drawn and sent medium to flow to two opposite directions by the viscous friction in the disk 4 surface interface layers, thereby forms the liquid stream of two bursts of convection current.A direction is that quilt is drawn send medium to enter from the district 6 that sinks that inwall and dividing plate 5 by housing 1 constitute, and through the zone between the disk of rotor 2, passes the auxiliary extrusion 10 that is made of same wall and accessory septa 8 in the housing 1; Another direction is that quilt is drawn send medium to enter from the auxiliary district 9 that sinks that inwall and accessory septa 8 by housing 1 constitute, and through the zone between the disk of rotor 2, passes the extrusion district 7 that is made of same wall and dividing plate 5 in the housing 1.

In the flowing medium device for drawing-in and pumping-out, just form two strands of liquid streams that direction is opposite thus.And the moving direction of per share liquid stream is invariability, like this, just can guarantee to get rid of the energy loss that is consumed in change flowing medium moving direction, and reduce being consumed in the energy loss that when inner walls flows, rubs and caused because of no column part significantly, just can improve double fluid thus to the efficient of device and total throughput.
