Technical Field

[0001] The utility model relates to the technical field of separation and filtration, in particular to a separation sedimentation mechanism and a liquid level meter. Background Art

[0002] All natural gas transmission and distribution stations will be equipped with separators to separate solid and liquid impurities in natural gas. The separated solid and liquid impurities are deposited in the separator, and the liquid level in the separator is displayed by a liquid level gauge. Generally, when the liquid level reaches two-thirds of the height of the liquid level gauge, the solid and liquid impurities in the separator need to be discharged and discharged into the sewage buffer tank for storage, and then transported to the sewage treatment station for purification.

[0003] The magnetic flap level gauge generally used in existing separators relies on the magnetic column to drive the magnetic float to flip to display the liquid level height. However, it is found in production that solid and liquid impurities in the separator are easy to adhere to the magnetic column, resulting in uneven magnetic distribution of the magnetic column, causing large deviations in the float display, and there is a risk of excessive liquid level flipping, causing natural gas to be contaminated by solid and liquid impurities, affecting production. Utility Model Content

The partition 2 divides the shell 1 into a first chamber 13 and a second chamber 14, and the second chamber 14 is located above the first chamber 13. The inlet 11 is connected to the first chamber 13, and the outlet 12 is connected to the second chamber 14. A channel 21 is provided on the partition 2, and a control rod 3 extends into the shell 1. The end of the control rod 3 located outside the shell 1 is connected to the control part 31, and the end of the control rod 3 extending into the shell 1 is provided with a plug 32, and the plug 32 can be adapted to block the channel 21.

[0035] like Figure 1 , Figure 3 As shown, a separation and sedimentation mechanism of this embodiment has a shell 1 that is cylindrical, and an inlet 11 and an outlet 12 are arranged on opposite sides of the shell 1. The inlet 11 and the outlet 12 are respectively connected to corresponding pipes to facilitate combined connection with other mechanisms. The shell 1 is divided into a first chamber 13 at the bottom and a second chamber 14 at the top by a horizontally arranged partition 2. The inlet 11 is connected to the second chamber 14, and the outlet 12 is connected to the first chamber 13. The control rod 3 extends vertically into the second chamber 14 from the top of the shell 1. The control rod 3 is rotatably connected to the shell 1. By pushing or rotating the control rod 3, the plug 32 can be driven to approach or move away from the channel 21 arranged on the partition 2, and the plug 32 is used to achieve the blocking or connection control of the channel 21.

[0037] Furthermore, in order to prevent the medium in the housing 1 from escaping when the control rod 3 is actuated, a seal 6 is preferably provided between the control rod 3 and the housing 1 .

[0038] Preferably, in a separation and sedimentation mechanism of this embodiment, a sewage outlet 15 is provided at the bottom of the first chamber 13, and the sewage outlet 15 is connected to the blocking mechanism 4.

[0039] A separation and sedimentation mechanism of the present embodiment divides the internal space of the shell 1 into two chambers arranged up and down, and the liquid entering the shell 1 first enters the first chamber 13 at the bottom and then overflows into the second chamber 14 at the top, so that the solid and liquid impurities in the liquid are not easy to enter the second chamber 14 under the action of gravity, and settle in the first chamber 13 to achieve the sedimentation and separation of solid and liquid impurities. The structural principle is simple. At the same time, the connection and partition control of the two chambers are realized by the control rod 3, and the artificial control of the liquid flow in the sedimentation and separation process can be realized, which is convenient for matching with different use conditions. When in use, the connection between the first chamber 13 and the second chamber 14 is realized by adjusting the control rod 3, and the liquid is input into the first chamber 13 from the inlet 11, and the solid and liquid impurities in the liquid are settled in the first chamber 13.

[0048] A separation and sedimentation mechanism of this embodiment is provided with a buffer mechanism 8 below the position where the liquid inlet pipe 7 passes through the partition 2. The liquid flow input into the first chamber 13 from the liquid inlet pipe 7 directly impacts the buffer mechanism 8, thereby changing the flow direction and speed of the liquid flow, so that the solid and liquid impurities therein are more easily settled in the first chamber 13.

[0049] Preferably, the buffer mechanism 8 includes a plurality of buffer plates 81 stacked in layers, the buffer plates 81 are provided with flow guiding slopes, and the plurality of buffer plates 81 are connected by connecting columns 82, and the area of ​​the buffer plates 81 increases along the direction of the liquid flow.

On the one hand, the buffer plates 81 bear the impact of the liquid flow from top to bottom, so as to achieve dispersion of the liquid flow, and the solid and liquid impurities in the liquid flow can be separated and settled more easily. On the other hand, after the liquid flow impacts the buffer plates 81, it flows along the slopes formed by the stacking of the buffer plates 81, and the flow speed is slowed down. The flow speed is reduced, which can further improve the sedimentation effect of the solid and liquid impurities in the liquid flow, and there are inclined gaps between adjacent buffer plates 81 that are inclined downward, so that the solid and liquid impurities in the liquid flow are not easy to accumulate between the buffer plates 81.
