Description
Technical Field
The utility model relates to a clean district drainage technical field, especially a clean district prevents flowing backward drainage device.
Background
In the prior art, because the water outlet of the clean area equipment is directly connected with the sewage discharge pipeline, when pressure exists in the sewage discharge pipeline or external pressure is applied, sewage is easily caused to enter the equipment through the sewage discharge pipeline, so that other materials in the equipment or the equipment are polluted, and an improved technology is urgently needed to solve the problem in the prior art.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a clean area anti-backflow drainage device which has simple structure, convenient drainage and can prevent sewage from entering equipment.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a clean district prevents flowing backward drainage device, includes the drainage device body, be provided with the delivery port on the left lateral wall of drainage device body, be provided with the water inlet on the right lateral wall of drainage device body, the height that highly is less than of delivery port the height of water inlet just is higher than the bottom of drainage device body, the inside fixedly connected with baffle of drainage device body, the top of baffle with the top of drainage device body is levelled and level mutually, the bottom of baffle unsettled and with the lower edge of delivery port is levelled and level mutually, the inboard of water inlet just in swing joint has the baffle on the inside wall of drainage device body, the baffle can shelter from completely when closing the water inlet.
The top of drainage device body is installed and is made the protection casing by the glass steel material.
The drainage device body and the partition plate are both made of stainless steel.
The baffle is made by the silica gel material.
The utility model has the advantages that: compared with the prior art, the water inlet of the utility model is connected with the water outlet of clean area equipment, the water outlet is connected with a sewage discharge pipeline, the baffle is arranged and is level with the lower edge of the water outlet, so that the water seal is formed inside the drainage device body, the water inlet is isolated from the water outlet, and the sewage is prevented from flowing backwards; set up the baffle, can prevent that the sewage of pressurized from entering into the water inlet through the delivery port, and then get into equipment to produce the pollution.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a cross-sectional view of the present invention;
FIG. 2 is a schematic view of the structure of the baffle in draining;
FIG. 3 is a schematic view of the structure of the baffle plate when sewage flows backward.
Detailed Description
Referring to fig. 1 to 3, a clean area backflow prevention drainage device comprises a drainage device body 1, a water outlet 2 connected with a sewage discharge pipeline is arranged on the left outer side wall of the drainage device body 1, a water inlet 3 connected with a water outlet of clean area equipment is arranged on the right outer side wall of the drainage device body 1, the water outlet 2 is lower than the water inlet 3 and higher than the bottom of the drainage device body 1, a partition plate 4 is fixedly connected (welded in the embodiment) inside the drainage device body 1, the top end of the partition plate 4 is flush with the top of the drainage device body 1, the bottom end of the partition plate 4 is suspended and flush with the lower edge of the water outlet 2, a baffle plate 5 is movably connected to the inner side of the water inlet 3 and the inner side wall of the drainage device body 1, and when the baffle plate 5 is closed, the water inlet 3 can be completely shielded; the partition plate is arranged, so that water seal can be formed inside the drainage device body, the water inlet is isolated from the water outlet, and sewage is prevented from flowing backwards; set up the baffle, can prevent that the sewage of pressurized from entering into the water inlet through the delivery port, and then get into equipment to produce the pollution.
The protection casing 6 that is made by glass steel material is installed at the top of drainage device body 1, not only can observe the inside condition of drainage device body 1, and corrosion resistance is good moreover.
The drainage device body 1 and the partition plate 4 are made of stainless steel materials, and corrosion resistance is good.
Baffle 5 is made by the silica gel material, and the leakproofness is good.
In the embodiment, during drainage, water flowing out of the drainage port of the clean area equipment pushes the baffle 5 open, enters from the water inlet 3 and is discharged through the water outlet 2, and when water in the drainage device body 1 forms water seal with the baffle 4, the water inlet 3 is isolated from the water outlet 2, so that sewage can be prevented from flowing backwards; when the pipeline pressurized of discharging sewage, when sewage flows back through delivery port 2 and gets into drainage device body 1 in, sewage promotes the inboard baffle 5 of water inlet 3 for baffle 5 shelters from water inlet 3 completely, can prevent that sewage from passing through water inlet 3 and then entering into equipment, thereby pollutes other materials in equipment or the equipment.
The above embodiments do not limit the scope of the present invention, and those skilled in the art can make equivalent modifications and variations without departing from the overall concept of the present invention.
