Description

The blow-off pipe antiplugging device

The utility model belongs to building blowdown sewer pipe antiplugging device and makes the field.

Background technology of the present utility model is: notification number is: CN2157231Y, title " sewer pipe antiplugging device ", and imitate between arc 1 and arc retention plate 2, and be provided with boss 4 for anti-blocking 3 of this device in the upper edge of arc 1.This antiplugging device is placed in the sewage draining exit of toilet stool pond: not enough point: the one, and artificially taken away easily, and do not have anti-blocking effect by the people, the 2nd, outside this antiplugging device was directly exposed to, stool was difficult for rinsing, thereby unhygienic, polluted room air, and people are difficult to accept.

Purpose of design of the present utility model is: avoid weak point of the prior art, design and a kind ofly can play blocking-proof result effectively, can conceal fraud ground again antiplugging device is inserted blow-off line antiplugging device in the blow-off line.

Design scheme of the present utility model is: in existing blow-off line the antiplugging device that is used to block nonhydratable foreign matter is installed.Its structural concept: a kind of blow-off pipe antiplugging device, be equipped with antiplugging device (2) in the sewage outlet of P type bend pipe (1) or in the sewage import of person in charge's skew T.Antiplugging device (2) is made of backing ring (6) and curved knife (5), and backing ring (6) is the garden circulus, and curved knife (5) is fixed on the inwall of backing ring (6).Curved knife (5) is 2--9.The cambered surface of curved knife (5) is a blade.

The utility model is compared with background technology, the one, structure design novelty, uniqueness, simple, cost is low, the 2nd, this antiplugging device can be inserted in the blow-off line effectively, prevent nonhydratable different obstruction blow-off line, thereby guarantee the unblocked of blow-off line, bring peacefulness and harmony for the inhabitation family, the 3rd, easy for installation, simple and direct, practical.
