Description
Technical Field
The utility model relates to a coking production maintenance technical field specifically is a ponding siphon extraction element in cofferdam.
Background
The coking chemical production area has more tower bodies and tanks, which are usually matched with cofferdams, and the prior cofferdams have the problem of more accumulated water after raining; the problem of water accumulation in the cofferdam is solved, a submersible pump is used for pumping water in the existing stage, and the problems of the method are as follows:
1. the equipment investment is large, the submersible pump is placed in the deep pit for pumping water, and the pump body is placed in the open air for a long time and is easy to damage; and requires electricity.
2. The drainage is discontinuous, and the immersible pump draws water and needs the manual work to start the pump, can not discharge the interior ponding of cofferdam in time.
3. The operation is inconvenient, and when the rainwater is more, the internal cofferdam of region is more, probably has the condition that needs connect the immersible pump temporarily.
Disclosure of Invention
The utility model aims at providing a ponding siphon extraction device in cofferdam in order to solve the problem that exists is taken out to above-mentioned current cofferdam ponding.
The utility model has the following concrete scheme: the utility model provides a ponding siphon draw-out device in cofferdam, including the cofferdam, the bottom is equipped with a ponding hole in the cofferdam, be equipped with a siphon in the ponding hole, siphon one end is worn out the cofferdam and is extended to in the groundwater tank, the groundwater tank is located the below of cofferdam, the other end opening top cover of siphon has a sleeve pipe, sheathed tube internal diameter is greater than the external diameter of siphon, the sleeve pipe lower extreme is equipped with the opening, the sleeve pipe upper end is equipped with a shrouding, be equipped with the through-hole on the shrouding, through-hole department is connected with the production water pipe, the production water pipe outer end is connected to the process water, be equipped with the valve on the siphon.
The outside that the siphon is located the cofferdam is equipped with horizontal pipe section, and the outer end of horizontal pipe section is equipped with the retaining pipe section of kickup, highly being less than of retaining pipe section the bottom in ponding hole.
Production water pipe and siphon all adopt DN25 pipe diameter, the sleeve pipe adopts DN50 pipe diameter, is equipped with the valve on the production water pipe.
The difference in height of the lowest point of siphon pipe stretching into the underground water tank to the bottom surface of the water collecting pit is larger than 300mm.
The utility model discloses following beneficial effect has: 1. energy conservation and environmental protection; the investment of a submersible pump and other related facilities is reduced; 2. the maintenance workload is small; after the primary input, the water is discharged by utilizing the siphon principle; 3. the drainage is more timely.

FIG. 1 is a schematic view of the structure of the present invention;
in the figure: 1-production water pipe, 2-valve, 3-cofferdam, 4-sleeve, 5-siphon, 51-horizontal pipe section, 52-water storage pipe section, 6-water accumulation pit, 7-valve, 8-underground water tank.
Detailed Description
Referring to fig. 1, the embodiment is a ponding siphon draw-out device in cofferdam, including three cofferdam 3, the bottom is equipped with a ponding pit 6 in every cofferdam 3, be equipped with the siphon 5 of a DN25 in the ponding pit 6, 5 one ends of siphon wear out the cofferdam 3 and extend to in the basin 8, basin 8 is located the below of cofferdam 3, the other end opening top cover of siphon 5 has a sleeve pipe 4 of a DN50, the sleeve pipe 4 lower extreme is equipped with the opening, the sleeve pipe 4 upper end is equipped with a shrouding, be equipped with the through-hole on the shrouding, through-hole department is connected with the production water pipe 1 of DN25, production water pipe 1 outer end is connected to the process water, be equipped with valve 7 on the siphon 5.
In the embodiment, a horizontal pipe section 51 is arranged outside the cofferdam 3 of the siphon 5, an upward bent water storage pipe section 52 is arranged at the outer end of the horizontal pipe section 51, the height of the water storage pipe 52 exceeds that of the horizontal pipe section 51 by about 20mm, and the height of the water storage pipe section 52 is lower than the bottom of the water accumulation pit 6.
In this embodiment, a valve 2 is arranged on the production water pipe 1.
The height difference between the lowest point of the underground water tank 8 and the bottom surface of the sump 6, which is formed by the siphon 5, is more than 300mm.
The embodiment utilizes the siphon principle to automatically pump out the accumulated water in the cofferdam 1 and guide the accumulated water into the underground water tank 8 with lower terrain, thereby avoiding the use of a submersible pump and saving electric energy; and drainage is more timely.
