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 Thoroughly.

Preferably, the inner wall of sewage draining exit 11 is equipped with screw thread, and sealing-plug 12 uses screw thread rubber stopper, 12 row of being tightened in of sealing-plug In dirty mouth 11, this sealing means are convenient for operation, and sealing means are preferable.

Preferably, a sealing ring 6 is installed between upper end cover 2 and shell 1, sealing ring 6 be squeezed water filter plate 24 with Between the upper surface of shell 1, preferable sealing effect can be played, leak is prevented.

When using external pressure type ultra-filtration membrane putamina described in the utility model, film wire 5 is wrapped in outside central tube 4, is filled in In space between heart pipe 4 and shell 1, raw water enters from water inlet pipe 22, by the shunting of water filter plate 24, uniformly flows to film wire 5, Filtering by film wire 5 flows into central tube 4, and the water purification by filtering later is flowed out along central tube 4 from outlet pipe 32, uses one After the section time, sewage draining exit 11 can be opened, sewage is discharged.

One piece of water filter plate 24 is arranged since upper end cover 2 uses special construction in the utility model in upper end cover 2, can be right Water inlet is played the role of a buffering and is shunted, and compared to the prior art for the mode of side water inlet, water inlet and filtering are more Uniformly, 5 utilization rate of ultrafiltration membrane filaments improves, while having a buffer function to water flow, can improve since intake pressure is excessive, quality Slim and frahile film wire 5 is easy breakage, the shorter phenomenon of service life under high pressure water flow strikes.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
