End face impaction type hoop

Abstract

The invention discloses an end face impaction type hoop. The end face impaction type hoop is mainly characterized in that a circle of sealing face is integrally formed at one end of the hoop in a radially inward direction, so that the functions of the conventional hoop are realized, the sealing face can be exactly matched with an end face of a rigid pipe to tightly clamp a flexible material between the sealing face and the end face of the rigid pipe so as to form an end face seal, and materials can be effectively prevented from leaking outwards; besides, the flexible material is radially pressed inwards at the end face seal, so that the flexible material has a small upstream caliber and a large downstream caliber by taking the part which is pressed inwards as a dividing line, the letdown of the materials in the flexible material is facilitated, and the smooth letdown of the materials can further prevent the materials from leaking outwards.

Description

technical field [0001] The invention relates to a hoop, in particular to a hoop used for connecting flexible materials with rigid pipes. Background technique [0002] The pollution of drinking water sources in my country is becoming more and more serious, and there are many types of organic substances in water sources. In the process of water treatment, activated carbon is usually added to adsorb and remove organic substances and other impurities in raw water. Due to the large specific surface area of ​​powdered activated carbon, it has strong adsorption, which can effectively remove the color, turbidity and peculiar smell of raw water, and effectively reduce the pollutant content in raw water. [0003] The dosing method of powdered activated carbon usually adopts the wet dosing method, that is, after mixing the powdered activated carbon with water, the mixture of powdered activated carbon and water is injected into the raw water through a metering pump. The existing manual...

AI Technical Summary

Problems solved by technology

Since the powdered activated carbon material package is flexible and the feeding port of the feeding device is a rigid metal pipe or plastic pipe, it is not possible to use pipes to connect commonly used flanges, and it is more appropriate to use hoop-type fastening devices to connect. However, the existing The technical hoop cannot meet the requirements in terms of sealing performance, and there will still be a small amount of powdered activated carbon that will easily leak from between the outlet of the material bag and the inlet of the feeding device. Therefore, it is necessary to develop a suitable for connecting the material bag. The material outlet and the material inlet of the feeding device and the hoop that can ensure the sealing of the connection
