Dual-water-seal and dual-gas-seal clean floor drain for pharmaceutical workshop

Abstract

The invention relates to a double-water-air-seal clean floor drain in a pharmaceutical workshop. Including the floor drain body, the floor drain body is provided with a partition, and the floor drain body is provided with a connecting cup passing through the partition; the floor drain body is provided with an upper water seal cylinder and a lower water seal cylinder; Buckle on the outside of the connecting cup, there are gaps between the upper water sealing cylinder and the connecting cup, and between the upper water sealing cylinder and the partition to form a sewage channel; the lower water sealing cylinder is located at the lower part of the partition, and the sleeve is placed on the outside of the connecting cup. There are gaps between the sealing cylinder and the partition, and between the lower water sealing cylinder and the communication cup to form a sewage channel; the bottom of the communication cup is provided with a float valve for blocking the sewage channel. The double-water-air-sealed clean floor drain of a pharmaceutical workshop provided by the present invention has two water seals of the upper water seal chamber and the lower water seal chamber, and has two gas seals of a check valve and an air blocking floating ball. The sealing performance of the clean floor drain is greatly improved.

Description

technical field [0001] The invention relates to a floor drain, in particular to a clean floor drain in a pharmaceutical workshop with double water seals and double air seals. Background technique [0002] With the full implementation of the 2010 version of GMP, domestic pharmaceutical companies have paid more attention to the control of various pollution sources and potential pollution sources in pharmaceutical workshops, and pharmaceutical equipment has also achieved considerable development in recent years. The current pharmaceutical equipment has high production efficiency and requires The amount of steam, air and water discharged has increased a lot. In production, when multiple devices discharge sewage at the same time, the sewage system of the workshop sometimes generates short-term pressure, especially when designing drawings, exhaust and drainage are designed together In the workshop, this kind of situation is more common.

Problems solved by technology

[0002] With the full implementation of the 2010 version of GMP, domestic pharmaceutical companies have paid more attention to the control of various pollution sources and potential pollution sources in pharmaceutical workshops, and pharmaceutical equipment has also achieved considerable development in recent years. The current pharmaceutical equipment has high production efficiency and requires The amount of steam, air and water discharged has increased a lot. In production, when multiple devices discharge sewage at the same time, the sewage system of the workshop sometimes generates short-term pressure, especially when designing drawings, exhaust and drainage are designed together In the workshop, this kind of situation is more common. The floor drain currently used cannot meet the sealing problem of the sewage system under pressure. In order to solve the pressure of the sewage system, the potential risk of air or sewage in the sewage system being poured back into the pharmaceutical workshop occurs. , the present invention designs a safer double-water-air-seal clean floor drain, which has more important practical significance in pharmaceutical workshops
