The floor drain is provided with a water trap with a water seal height of not less than 150 mm. A water stop ring is provided on the outside of the floor drain body to enhance the waterproofness and air tightness of the floor drain during pre-buried installation. The stainless steel movable mesh frame cover plate and the built-in filter element constitute a drainage filtration structure, which can prevent hair and animal tissue in the drainage from entering the drainage system pipe.

[0003] The above structure has two main defects:

[0004] (1) The drainage water collection port is a funnel-shaped open structure that cannot be effectively sealed. Therefore, the drainage pipe cannot be pressure tested. The pipe welding quality can only be checked by filling and flowing water tests. It is difficult to reliably check whether the drainage pipe welding quality and the air tightness of the system pipes meet the air tightness requirements of high-level biosafety facilities, and there is a risk of biological leakage. High-level biosafety laboratories need to discharge live toxic wastewater, which contains pathogenic biological factors, and there is a risk of leakage and spread of pathogenic biological factors.

[0005] (2) The water seal of the floor drain trap in the biosafety laboratory is deep to ensure airtightness, which makes it difficult to clean the sediment in the trap. Utility Model Content

[0006] The utility model provides a biosafety floor drain capable of undergoing a pressure test, the purpose of which is to overcome the above-mentioned deficiencies in the prior art, realize the feasibility of the pressure test, eliminate the risk of biological leakage, and facilitate the cleaning of sediment in the water trap.

The top of the drainage water collection port is detachably provided with a cover plate, which is a stainless steel movable mesh frame cover plate. The filter cartridge is inserted into the top of the drainage cylinder body and the top limit is clamped at the bottom of the drainage water collection port. The drainage cylinder body is connected to a pressure device or a backwashing device through an internal thread. The pressure test of the drainage pipe or the backwashing of the floor drain trap to clean the sediment in the trap is realized.

[0008] Preferably, the outer circumference of the top of the drainage water collection port is connected to a protective sleeve extending toward the bottom of the drainage water collection port and the middle of the drainage cylinder, and the protective sleeve is bowl-shaped, so as to protect the outer side of the drainage water collection port.

[0009] Preferably, it also includes an embedded sleeve, which is an embedded stainless steel sleeve, a water stop ring is welded in the circumferential direction of the middle and lower part of the embedded sleeve, the ring is a stainless steel ring, the embedded sleeve is embedded in the concrete structure layer, and above the concrete structure layer is a floor cushion layer, the sleeve is inserted into the reserved hole on the floor cushion layer and inserted into the inner side of the embedded sleeve together with the bottom end of the drainage cylinder, fine stone concrete is filled between the inner side of the embedded sleeve and the outer side of the drainage cylinder, and a ring supporting the outer side of the drainage cylinder and the bottom of the fine stone concrete is welded at the inner bottom of the embedded sleeve.
