Air pressure type sewer pipe dredging device

Abstract

The invention relates to the field of sewer pipe dredging devices, and provides an air pressure type sewer pipe dredging device, which is characterized by comprising an air outlet end, a compressed air storage tank, an inflator, a plunger and a trigger and also comprising a balloon, two air pipes, a two way valve, a quick plug and a dredging tool, wherein on end of one air pipe penetrates the balloon; one end of the other air pipe is connected with the balloon, and the other end of the other air pipe is connected with the inlet end of the two way valve; and the other end of the air pipe penetrating the balloon and the other end of the air pipe connected with the inlet end of the two way valve are connected with an air outlet end of the dredging tool through the quick plug. The balloon is inflated by the dredging tool, so that the balloon is expanded to block the opening of the sewer pipe; the air is compressed and stored in the compressed air storage tank, and after a certain pressure is reached, the trigger is triggered to instantly release the compressed air from the air pipe penetrating the balloon to the sewer pipe, so that obstruction in the sewer pipe is dispersed under the instant pressure impact to dredge the sewer pipe.

Description

(1) Technical field: [0001] The invention relates to a dredging device for cleaning sewer pipes, in particular to a cleaner for dredging household sewer pipes by using air pressure. (two) background technology: [0002] There is a pneumatic sewer dredger, commonly known as "one gun through" or "one through", through the rubber disc plug with a hole in the center, relying on manual pressure to block the mouth of the sewer pipe, and then compress the air into a device with instant opening. After a certain pressure is reached, the compressed air is released instantly and enters the sewer pipe from the center hole of the rubber disc plug, thereby exerting an instantaneous impact pressure on the blockage in the sewer pipe to blow the blockage away. Spread out to achieve the effect of dredging the sewer pipe. Although such a pneumatic sewer dredger can also play a certain role in semi-blocked sewer pipes to a certain extent, but for relatively solid blockages, such a limited inst...

AI Technical Summary

Problems solved by technology

Although such a pneumatic sewer dredger can also play a certain role in semi-blocked sewer pipes to a certain extent, but for relatively solid blockages, such a limited instantaneous impact pressure is still not enough to blow them out. In addition, due to the limited strength and endurance of manpower, the mouth of the sewer pipe is not tightly blocked by the rubber disc plug. On the one hand, dirty water splashes everywhere, causing on-site pollution and even polluting the operator's face and body; on the other hand Leakage weakens the pressure of the compressed air, that is, the instantaneous impact pressure is weakened, and the dredging effect is greatly reduced; repeated operations, each instant impact pressure cannot form a cumulative impact pressure, and simply repeated work cannot achieve a good dredging effect
