Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical equipment, in particular to a plugging type floor drain used in petrochemical plants. Background Art
[0002] In the equipment area of petrochemical enterprises, when it rains, rainwater will be mixed with a large amount of toxic and harmful pollutants such as factory exhaust gas and acidic gas in the air and fall to the factory ground. These rainwater will also be mixed with debris such as grease, suspended solids and heavy metals with high concentrations on the ground. When it rains for a long time, factory staff will use sandbags to seal the floor drains to divert the rainwater. That is, the initial polluted rainwater 15 minutes before the rain flows from the floor drain through the sewage well and finally flows into the sewage pool. After 15 minutes, sandbags are used to seal the floor drains to discharge the unpolluted rainwater directly into the rainwater pool through the drainage ditch.
[0003] However, on the one hand, the overall sealing of the sandbags is not tight. Even when used to block floor drains, a large amount of unpolluted rainwater still leaks into the sewage pool, which will increase the workload of public works and third-party sewage treatment companies and increase operating costs. On the other hand, the sandbags are prone to aging and damage after long-term use, and fine sand flows into the sewage well, increasing the amount of sludge in the sewage well and causing blockage of the sewage well floor drain. Moreover, the sandbag blocking must be carried out 15 minutes after the rain, and the staff need to block it manually and check the sealing one by one, which will increase the work intensity of the staff. Utility Model Content

When the support rod 22 in the outer shell 2 slides to the limit hole 17, the support rod 22 can be firmly locked in the limit hole 17 to avoid The support rod 22 is not required to slide back into the notch 15, thereby avoiding the cover plate 11 from sealing the outer shell 2, and rainwater within 15 minutes of rain can flow into the sewage well through the cover body 1 and the outer shell 2. The opening and closing degree between the cover body 1 and the outer shell 2 can be adjusted by using different bayonet 16; a first sealing groove 13 is provided on the outer side of the cover wall, a first sealing ring is provided on the first sealing groove 13, two first sealing grooves 13 are provided, and two first sealing rings are provided opposite to each other; an opening adapted to the cover plate 11 is provided on the top of the outer shell 2, a second sealing groove 21 is provided on the outer side of the outer shell 2, a second sealing ring is provided on the second sealing groove 21, two second sealing grooves are provided, and two second sealing rings are provided opposite to each other; a support rod 22 passing through the central axis is provided in the outer shell, and the support rod 22 is adapted to the notch 15, and a detachable filter screen 23 is provided at the bottom of the outer shell 2 to prevent debris from entering the floor drain.
[0029] Furthermore, a vertical rod is provided at the top of the cover plate 11, and the vertical rod has a clear mark. The clear mark rod is designed to prevent the non-polluted rainwater from being too deep in extreme weather and the floor drain position from being lost in abnormal circumstances.
[0030] The working principle and use process of this utility model: Figure 7The utility model is shown in its initial state. When in use, the outer shell 2 is placed in the wellhead of the sewage well connected to the sewage pool. At this time, the notch 15 of the cover body 1 is aligned with the support rod 22 of the outer shell 2 and the cover body 1 is inserted into the outer shell 2. When it rains, the handle 12 is used to lift the cover plate 11. When the support rod 22 is aligned with the bayonet 16, the cover body 1 is rotated, and the support rod 22 slides into the bayonet 16. When the support rod 22 slides to the position of the limit opening 17, the cover body falls downward under the action of gravity, and the support rod 22 is pressed at the limit opening 17 (that is, the cover body 1 is stuck on the outer shell 2). When the outer shell 2 is open, the cover plate 11 is higher than the outer shell 2 by a certain height. Within 15 minutes of rain, polluted rainwater and polluted rainwater falling on the ground will flow into the outer shell 2 and then flow into the sewage pool, while the debris will be blocked by the filter screen 23. After 15 minutes of rain, the staff will lift the cover plate 11 by the handle 12, rotate the cover body 1, make the support rod 22 slide out of the bayonet 16 and return to the slot 15, and then press the cover plate 11 down to make the support rod 22 slide to the top of the slot 15. At this time, the cover body 1 and the outer shell 2 are completely overlapped, and the cover plate 11 completely covers the outer shell 2. Figure 8 As shown, the first sealing ring seals the outer shell 2, and the second sealing ring seals the sewage well to prevent rainwater from flowing into the sewage well after 15 minutes of rain, thereby reducing the workload of public works or third-party sewage treatment companies and reducing the operating costs of petrochemical companies.
