Mechanical floor drain for preventing gas in water drainage pipeline from overflowing and dispersing

Abstract

The invention provides a mechanical floor drain for preventing gas in a water drainage pipeline from overflowing and dispersing. The mechanical floor drain comprises a cover plate, an encircling plate, a closing plate, a water baffle, a counterweight block, a shaft bracket and a pivot, wherein the encircling plate is a cylindrical shape with openings in the upper and lower ends; the cover plate is covered at the upper end of the encircling plate, and a plurality of water guide holes are formed in the cover plate; the closing plate is covered on part of the area of the lower end of the encircling plate aslant; the other part of the area of the lower end of the encircling plate is covered by the water baffle; the water baffle is extended to the lower side of the closing plate; the shaft bracket is arranged below the closing plate, and the pivot is penetrated through the shaft bracket; the pivot is fixedly connected with the water baffle to ensure that the water baffle can be rotated around the pivot; the counterweight block is positioned at the end of the water baffle extended to the lower side of the closing plate so as to ensure that the water baffle is tightly covered on the opening in the lower end of the encircling plate from bottom to top and keeps horizontal balance under the gravity action of the counterweight block; a water stilling area capable of containing a certain amount of water is formed above the closing plate and the water baffle in the encircling plate. The mechanical floor drain provided by the invention does not rely on water seal, can be used for preventing smelly gas from overflowing and dispersing, and can not influence the automatic water drainage of the floor drain.

Description

technical field [0001] The invention relates to the technical field of building water supply and drainage, in particular, the invention relates to a mechanical floor drain for preventing gas overflow and diffusion in drainage pipes. Background technique [0002] In the building room used in semiconductor production and manufacturing, when the wastewater generated by the equipment passes through the floor drain and the discharge pipe to the wastewater treatment station, due to the reaction of certain deposits, some volatile odorous gases will overflow, thus Cause environmental pollution and gas detection system (MDA) alarm. Currently used floor drains cannot prevent the overflow of odorous gas, because the currently used floor drains adopt a water-sealed principle. However, due to the water-sealed method, it is necessary to ensure that there is a certain amount of water in the floor drain to play a sealing role; and if the time is too long, the water in the water seal will d...

[0002] In the building room used in semiconductor production and manufacturing, when the wastewater generated by the equipment passes through the floor drain and the discharge pipe to the wastewater treatment station, due to the reaction of certain deposits, some volatile odorous gases will overflow, thus Cause environmental pollution and gas detection system (MDA) alarm

The currently used floor drains cannot prevent the overflow of odorous gases, because the currently used floor drains adopt the principle of water sealing

However, due to the water-sealed method, it is necessary to ensure that there is a certain amount of water in the floor drain to play a sealing role; and if the time is too long, the water in the water seal will dry and evaporate (water shortage), so it cannot be achieved in any Time Sealing Requirements
