The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figure 1-3, a kind of external pressure type ultra-filtration membrane putamina, including shell 1, upper end cover 2, lower cover 3 and central tube 4;
Shell 1 is the tubular structure of a both ends open, and the lower port of shell 1 is nearby equipped with sewage draining exit 11, the outlet peace of sewage draining exit 11
Equipped with a sealing-plug 12;Upper end cover 2 is removably mounted at the upper port of shell 1, and lower cover 3 is removably mounted at shell 1
Lower port.
The upper cover body 21 of upper end cover 2 an including umbrella, upper cover body 21 are equipped with a water inlet pipe 22, under upper cover body 21
Edge is downwardly extending a upper installation set 23, and the lower edge position of upper cover body 21 is additionally provided with one piece of horizontal water filter plate 24, drainage
Plate 24 is equipped with multiple filtration holes, and the center of water filter plate 24 is equipped with a vertical insertion pipe 25, the upper end closed of insertion pipe 25;
Upper installation set 23 and the upper port of shell 1 are detachably connected by screw thread.
The lower cover 31 of lower cover 3 an including umbrella, is equipped with an outlet pipe 32 in lower cover 31, outlet pipe 32 it is upper
The inner surface of lower cover 31 is stretched out at end, and the upper limb of lower cover 31 upwardly extends to form a lower installation set 33, lower installation set 33 with
The lower port of shell 1 is detachably connected by screw thread.The tube wall of central tube 4 is equipped with recirculation hole 41, and the upper end of central tube 4 is plugged on
On insertion pipe 25, the lower end of central tube 4 is plugged on outlet pipe 32.
Preferably, recirculation hole 41 is distributed gradually intensively from 4 upper end of central tube on the direction of 4 lower end of central tube.Due to
Using the filter type that the putamina uses for upper end intake lower end water outlet mode, such top hydraulic pressure is larger, lower part hydraulic pressure compared with
Small, for balancing water pressure, recirculation hole 41 on central tube 4 is distributed setting by the way of gradually intensive from top to bottom, can improve
Hydraulic pressure imbalance and the non-uniform phenomenon of filtering.
Preferably, it is set on shell 1 there are two symmetrical sewage draining exit 11, convenient for the sewage of two sides is discharged, blowdown is more
