Abstract

The utility model relates to a fully sealed clean floor drain, which belongs to the technical field of chemical equipment, and is mainly applied to the sewage discharge process of chemical industry, pharmaceutical industry, food industry, environmental protection industry and the like. A checkered plate, a floor drain shell cavity and a bubble cap are arranged at a sewer pipe orifice in turn; water leaking holes are formed in the checkered plate, so that water on a floor conveniently enters the checkered plate; a small amount of water is stored in the floor drain shell cavity, so that liquid sealing and air sealing are facilitated; the bubble cap covers the sewer pipe orifice, so that the effects of liquid sealing and air sealing are achieved through a small amount of water; a piston is arranged in the middle of the bubble cap and faces the sewer pipe orifice; the external diameter of the piston is matched with that of the sewer pipe orifice; and O-rings are arranged outside the piston.

Description

A kind of hermetically sealed Clean floor drain

Technical field:

A kind of hermetically sealed Clean floor drain belongs to technical field of chemical, is mainly used in the blowdown activities of industry such as chemical industry, pharmacy, food and environmental protection.

Background technology:

Hermetically sealed Clean floor drain is widely used in industrial circles such as chemical industry, pharmacy, food and environmental protection, is specially adapted to the blowdown of cleanroom and bacteria free room.It is through the card on Clean floor drain top the solids arresting in the sewage to be lived, and liquid is gone in the inner chamber of Clean floor drain through the card orifice flow, thereby liquid flows into the purpose that reaches blowdown in the sewer pipe in bubble-cap.It has solved and has unclogged and readjusted, cleaning, water seal, sealing gland, and the technical problems such as spray cooling during the aqueous vapor mixed flow, is the indispensable special purification equipment of all kinds of purification factory buildings, GMP authentication toilet and bacteria free room.But, though the successful solution of Clean floor drain at present commonly used unclog and readjust, cleaning, water seal, sealing gland, and technical problems such as spray cooling during the aqueous vapor mixed flow; But the occasion cleaning in that purification is had relatively high expectations is not solved completely; Its reason is: sewage flows in the sewer pipe in bubble-cap, because fluid-tight and sealing gland bubble-cap can not be taken out cleaning, is taken out cleaning like bubble-cap; Fluid-tight and sealing gland are destroyed, and do not have the effect of sealing.

Summary of the invention:

Can not clean fully for overcoming traditional hermetically sealed Clean floor drain, leave the problem at structure dead angle, a kind of hermetically sealed Clean floor drain of special proposition; Its structure is such: establish card, floor drain shell chamber, bubble-cap at the sewer pipe mouth at first successively, said card has leaking hole, and the water of being convenient on the floor gets into; Said floor drain shell has low amounts of water in the chamber; Be convenient to fluid-tight, sealing gland, said bubble-cap is covered on the sewer pipe mouth, reaches the effect of low amounts of water fluid-tight, sealing gland; Then, the bubble-cap middle part is added a piston, piston is towards the sewer pipe mouth, and said piston external diameter conforms to the sewer pipe mouth, piston peripheral hardware O type circle; In the time will clearing up floor drain; The piston pressed downward is stretched in the sewer pipe, and the O type circle outer through piston sealed sewer pipe fully, thereby can bubble-cap be taken out cleaning; Place, the dead angle of sewer pipe and floor drain cone also can be cleared up completely simultaneously; After cleaning out bubble-cap is loaded onto, injected that a certain amount of water reaches fluid-tight, piston was extracted when sealing gland required in the floor drain inner chamber in sewer pipe, but just operate as normal of Clean floor drain.

The advantage of the utility model is, successfully solved floor drain and in scale removal process, completely cut off with outside seal fully, is the have relatively high expectations desirable special equipment of occasion of cleaning.

Description of drawings:

Accompanying drawing 1 is the utility model structural representation;

Wherein: (1) card, (2) floor drain shell chamber, (3) bubble-cap, (4) piston, (5) O type circle, (6) sewer pipe mouth.

The specific embodiment:

Shown in accompanying drawing 1; On sewer pipe mouth (6), establish card (1), floor drain shell chamber (2), bubble-cap (3) at first successively, said card (1) has leaking hole, and the water of being convenient on the floor gets into; There is low amounts of water in the said floor drain shell chamber (2); Be convenient to fluid-tight, sealing gland, said bubble-cap (3) is covered on the sewer pipe mouth (6), reaches the effect of low amounts of water fluid-tight, sealing gland; Then, bubble-cap (3) middle part is added a piston (4), said piston (4) external diameter conforms to sewer pipe mouth (6), piston peripheral hardware O type circle (5).

Claims (1)

1. hermetically sealed Clean floor drain, comprising: card, floor drain shell chamber, bubble-cap, piston, O type circle, sewer pipe is characterized in that: piston is established at the bubble-cap middle part, and piston is towards the sewer pipe mouth, and said piston external diameter conforms to the sewer pipe mouth, piston peripheral hardware O type circle.
