Description

Rain and sewage isolation device for chemical tank areas

Technical Field

The utility model belongs to the technical field of chemical tank field sealing devices, and particularly relates to a chemical tank field rain and sewage isolation device.

Background

In the existing rain and sewage isolation device for the chemical tank area, after the rain and sewage is exhausted, a flashboard is generally used for sealing a pipeline, so that the chemical tank area is in a sealing state. As disclosed in CN214245618U, a gravity type rain gate with dirt blocking function is a gravity falling type gate, but in practical use, the structure has obvious disadvantages in use: 1. the water flow passes through the flashboard in a parallel flow mode, and sundries with larger specific gravity in the water flow are deposited below the flashboard, so that the flashboard is not tightly closed. 2. Impurities with lighter specific gravity and capable of floating on the water surface are stuck on the flashboard and the edges of the flashboard device, and the closing tightness of the flashboard is also affected. Once the situation is generated, manual removal is needed, and the chemical tank areas cannot be closed timely.

Disclosure of Invention

The utility model aims to solve the technical problem of providing the rain and sewage isolation device for the chemical tank areas, which can avoid the influence of sundries during rain and sewage drainage and can timely seal the chemical tank areas.

The utility model relates to a rain and sewage isolation device for a chemical tank field, which comprises a rain and sewage drain pipe, wherein the rain and sewage drain pipe is buried in a foundation and penetrates through a fire dike; the water inlet of the rain and sewage drain pipe is arranged at the bottom of the rain and sewage drain area of the chemical tank area; the water outlet is positioned in a drainage channel outside the chemical tank area, and the water outlet is upward; a lifting isolation cover is arranged above the water outlet.

Preferably, the lifting isolation cover comprises a bracket, a cover body and an electric control lifting structure, wherein the cover body is connected with the electric control lifting structure, and the electric control lifting structure is arranged on the rain and sewage drain pipe through the bracket.

Preferably, a rubber pad is fixed at the bottom of the cover body corresponding to the water outlet.

Preferably, the lifting isolation cover is an electric valve.

Compared with the prior art, the utility model has the beneficial effects that:

(1) According to the utility model, the micro fountain can be formed by the height difference of the water outlet and the water inlet when the rain and sewage are captured, so that sundries in the rain and sewage are prevented from accumulating or floating near the water outlet by the micro fountain, and a chemical tank area can be closed in time after the rain and sewage are discharged.

(2) Sundries which can influence the closing of the lifting isolation cover are settled or carried away through water drainage, so that manual intervention is avoided, manpower is saved, and the sealing efficiency is improved; and then the degree of fit with the automatically controlled lift isolation cover is higher, has reduced the error rate of automatic closure.

Detailed Description

The technical scheme of the utility model will be clearly and completely described below with reference to the accompanying drawings.

As shown in figure 1, a rain and sewage drain pipe 3 is buried in a foundation 1 below a rain and sewage drain area 4 of a chemical tank area, a water inlet 31 of the rain and sewage drain pipe 3 is arranged at the bottom of the rain and sewage drain area 4 of the chemical tank area, the rain and sewage drain pipe 3 penetrates through a fire dike 2, a water outlet 32 is positioned in a drain channel 5 outside the chemical tank area, the water outlet 32 faces upwards, and the height of the water outlet is lower than that of the water inlet 31 and higher than that of the drain channel 5; the water outlet 32 is provided with a lifting isolation cover 6.

The lifting isolation cover 6 comprises a support 61, a cover body 62 and an electric control lifting structure 63, the support 61 is fixedly arranged at the water outlet 32 of the rain and sewage drain pipe 3, the cover body 62 is positioned right above the water outlet 32, the shape of the cover body is matched with that of the water outlet 32, and a rubber pad is fixed at the bottom of the cover body 62 corresponding to the position of the water outlet 32, so that the sealing performance can be improved. The cover 62 is connected to the electric control lifting structure 63 to drive the cover 62 to leave or approach the water outlet 32 of the rain and sewage drain pipe 3, the base of the electric control lifting structure 63 is fixed on the bracket 61, and the bracket 61 is fixed on the rain and sewage drain pipe 3.

The electric control lifting structure 63 can be a screw rod connected with a motor, the screw rod is connected with a threaded hole formed in the cover body 62 to realize electric control lifting, and a motor signal is connected with a remote controller; or a push rod connected with a cylinder, the push rod is fixedly connected with the cover 62, and the cylinder is in signal connection with a remote controller.

As another implementation structure of the lift-off isolation cover 6, the lift-off isolation cover 6 may employ an electric valve.

The working principle of the utility model is as follows: the water inlet 31 of the rain and sewage drain pipe 3 is communicated with the rain and sewage drain well, rainwater and sundries in the chemical tank area enter the rain and sewage drain well, enter the drain canal 5 outside the chemical tank area through the rain and sewage drain pipe 3, and the sundries are flushed out of the water outlet 32 along with the rainwater and enter the drain canal 5, so that the rain and sewage generate a micro fountain effect at the water outlet due to the low height of the water outlet 32, and the sundries with lighter specific gravity float on the water surface are smoothly taken away by the water flow under the micro fountain effect of the water outlet and cannot stay near the water outlet; impurities with larger specific gravity can sink to the bottom of the rain and sewage drain pipe 3 or the drain canal 5 under the action of self gravity, are not influenced by the impurities in the sealing process, and can be smoothly sealed. An electric control lifting isolation cover 6 is arranged at the device water outlet 32, so that remote control is conveniently realized.

The rain and sewage isolation device for the chemical tank areas provided by the utility model has the advantages of simple structure, convenience in maintenance, easiness in operation, durability, construction cost of about ten thousand yuan per set, durability, difficult damage and capability of effectively solving the problem of loose closure of the flashboard.
