Description

The device for drawing-in and pumping-out of flowing 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 of daily life and industrial building and facility and regulating system 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 fixing garden dish 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 the garden cylindricality.Utilize the interior toughness frictional force of garden panel surface 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 garden cylindrical wall, simultaneously in fact the direction that flows changed by 180 °, then through extruding district's outflow.In the case, the part of MEDIA FLOW is to enter to sink the district from extruding the district through the gap overflow between the garden dish 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 device garden cylindrical section flows of 180 °, medium high speed flow, and medium from extrude the district through the gap overflow between the garden dish 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, being equipped with one in its housing comprises that the rotor that is fixed with a plurality of gardens dish on one and a center line along axle are fixed on the relative wall of housing and with this and constitutes the dividing plate (SU that sinks the district and extrude the district, A, 985444).In this device, the part of shell body wall is the garden cylindricality, and the garden is coiled the dividing plate of that end and made pectination shape, and the pectination part is arranged between the dish of garden.Wait to draw the medium that send and change the extrusion chamber over to from sinking the chamber by the toughness frictional force in the panel surface interface layer of revolvable rotor garden.Medium flows to and sinks the district, and is mobile along the internal surface of housing garden 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 garden post 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 gardens dish 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, adorns an accessory septa therein, and this dividing plate also is that the center line along axle is fixed on the identical wall of housing, and constitutes auxiliary district and the auxiliary district that extrudes of sinking with this.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 of fixing a plurality of gardens dish 4 thereon.Fixing one at the center line of the wall upper edge of housing 1 axle 3 and constituting the dividing plate 5 that sinks district 6 and extrude district 7 with this.According to the present invention, the perisporium of housing 1 constitutes a through slot; An accessory septa 8 is housed in this groove.Accessory septa 8 also is that the center line of edge axle 3 is fixed on the same wall of housing 1, constitutes the auxiliary district 9 that sinks with this and extrudes district 10 with assisting.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 of fixing a plurality of brake discs 4 thereon by the direction rotation of arrow A indication, treating in the device case 1 drawn and sent the toughness frictional force that medium coils in the 4 surface interface layers by the garden to flow to two opposite directions, thereby forms the liquid stream of two bursts of convection current.A direction is, drawn and send medium to enter with the district 6 that sinks that dividing plate 5 constitutes from the wall by housing 1, and the auxiliary extrusion district 10 that is made of identical wall of housing 1 and accessory septa 8 is passed in the zone between coiling through the garden of rotor 2; Another direction is, drawn and send medium to enter with the auxiliary district 9 that sinks that accessory septa 8 constitutes from the wall by housing 1, and the extrusion district 7 that is made of identical wall of housing 1 and dividing plate 5 is passed in the zone between coiling through the garden of rotor 2.

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 consumes in changing flowing medium moving direction, and reduce significantly and consume the energy loss that when shell body wall flows, rubs and caused in because of no garden post part, just can improve double fluid thus to the efficient of device and total throughput.
