Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a water-gas separation device for water outlet under a pneumatic dewatering process in foundation pit dewatering operations. Background Art

[0002] With the deepening of urban development, foundation pit excavation depths and areas are gradually increasing. To ensure smooth excavation, effective drainage of the soil within the excavation area has become a key prerequisite. With the growing popularity of green environmental protection concepts, dewatering and pumping technology has also undergone numerous technical improvements. Currently, pneumatic dewatering is widely used due to its advantages such as non-electrified dewatering, uninterrupted pumping, and simplified daily management.

[0003] Under the pneumatic precipitation pumping method, the groundwater extracted from the precipitation well and the gas generated by the pneumatic precipitation equipment are mixed and discharged from the water pipe together. The flow rate of the water output is measured using a flow meter. Due to the presence of gas, there will be a large deviation, and it is necessary to effectively separate the water-gas combination in the water pipe.

[0004] At present, the flow measurement of pneumatic precipitation in engineering projects is mostly done by installing a flow meter at the outlet of the water pipe. The flow recorded is the flow of the water-gas mixture, which is larger than the actual water output and has a large error. In addition, the water output from some precipitation wells contains sand, which often blocks the flow meter, making the promotion of pneumatic precipitation very difficult.

[0005] In order to solve the above problems, we provide a water-gas separation device that can separate water and gas, reduce the sand content in the water, and effectively measure the water output of the precipitation well. Utility Model Content

[0006] The utility model aims to overcome the deficiencies in the prior art and provide a water-gas separation device.

[0007] The purpose of the utility model is achieved as follows: a water-gas separation device comprises a box body, a water inlet pipe is provided on the left side of the box body, a drain pipe is provided on the right side of the box body, an exhaust pipe is provided on the top of the box body, a partition is provided in the box body, the partition is located in the lower part of the box body, and the partition divides the lower part of the box body into a sedimentation tank and a drainage tank, and the sedimentation tank is located on the left side of the drainage tank.

[0008] Furthermore, there are multiple water inlet pipes, and the water inlet pipes are located on the upper left side of the box.

[0009] Furthermore, the drainage pipe is located at the lower right part of the box body.

[0010] Furthermore, an openable and closable cover is provided at the upper end of the box body, and the exhaust pipe is located on the cover.

[0011] Furthermore, support legs are provided around the bottom of the box.

[0012] Furthermore, a flow meter is provided at the drain pipe to measure the amount of water discharged from the drain pipe.

[0013] When the utility model is used, water enters the box through the water inlet pipe, and the water discharged from the water in the box enters the sedimentation tank. After entering the sedimentation tank, the water fluidity becomes smaller, and a large amount of gas contained in the water is discharged from the water. The gas is discharged through the exhaust pipe above the box, thereby achieving gas separation in the water. At the same time, the water is precipitated in the sedimentation tank, and a large amount of mud and sand mixed in the water will be precipitated at the bottom of the sedimentation tank. When the water in the sedimentation tank overflows into the drainage tank through the partition, since the water at the bottom of the sedimentation tank has a higher sand content than the water at the top, the sand content of the water overflowing into the drainage tank through the partition will be greatly reduced. The water in the drainage tank is discharged through the drain pipe, thereby completing water-gas separation and reducing the amount of mud and sand in the water.

[0014] Beneficial effects: The device can separate and discharge a large amount of gas in the water. At the same time, a partition is provided to divide the lower part of the box into a sedimentation tank to precipitate the mud and sand in the water, while reducing the sand content in the water overflowing into the drainage tank. A flow meter is installed at the drainage pipe to make more accurate statistics on the water output of the pumping well; an openable cover is provided, and the box can be cleaned by opening the cover.

[0022] Example 1, as Figure 1—4, the purpose of the utility model is achieved as follows: a water-gas separation device comprises a box body 1, a water inlet pipe 5 is provided on the left side of the box body 1, a water outlet pipe is provided on the right side of the box body 1, an exhaust pipe 4 is provided on the top of the box body 1, a partition 6 is provided in the box body 1, the partition 6 is located in the lower part of the box body 1, and the partition 6 divides the lower part of the box body 1 into a sedimentation tank and a drainage tank, and the sedimentation tank is located on the left side of the drainage tank.

[0023] There are multiple water inlet pipes 5, which are located at the upper left side of the box body 1. The drain pipe 3 is located at the lower right side of the box body 1, and the position of the drain pipe 3 is lower than the upper surface of the partition 6; it is convenient for draining water into the drainage pool.

[0024] The upper end of the box body 1 is provided with an openable cover plate 7, and the exhaust pipe 4 is located on the cover plate 7. The openable cover plate 7 can facilitate regular cleaning of the box body 1.

[0025] Support legs 2 are provided around the bottom of the box 1 to facilitate supporting the equipment.

[0026] When the present invention is used, water enters the housing 1 through the water inlet pipe 5. The water discharged from the housing 1 through the water inlet pipe 5 enters the sedimentation tank. After the water enters the sedimentation tank, a large amount of gas contained in the water will be discharged from the water, and the gas will be discharged through the exhaust pipe 4 above the housing 1. At the same time, the water will be precipitated in the sedimentation tank, and a large amount of mud and sand mixed in the water will be precipitated at the bottom of the sedimentation tank. When the water in the sedimentation tank overflows into the drainage tank through the partition 6, since the water at the bottom of the sedimentation tank has a higher sand content than the water at the top, the sand content of the water overflowing into the drainage tank through the partition 6 will be greatly reduced. The water in the drainage tank can be discharged through the drain pipe 3 to complete the water-gas separation and reduce the amount of mud and sand in the water. At the same time, the water volume can be more accurately measured by the flow meter 10. Example

[0027] like Figure 4 As shown: the partition 6 is movable up and down inside the box body 1. Guide rails 9 are provided on the front and rear sides of the box body 1, and the partition 6 is movable up and down inside the guide rails 9. A horizontal plate 8 is provided at the lower part of the box body 1, and the sedimentation tank and the drainage tank are located above the horizontal plate 8. The drain pipe 3 is connected to the horizontal plate 8 at the bottom of the drainage tank. The drain pipe 3 is located at the bottom of the drainage tank, which is conducive to completely draining the water in the drainage tank; the partition 6 that can be moved up and down can be taken out when cleaning the inside of the box body 1, and the sediment in the sedimentation tank can be discharged through the drain pipe 3. At the same time, it is convenient to replace partitions 6 of different heights to change the water storage capacity in the sedimentation tank. By changing the water storage capacity, the sedimentation efficiency of the sediment in the water can be changed.
