Description

Technical Field

[0001] The utility model relates to the technical field of liquid level measurement, in particular to a water seal liquid level measuring device for a gas station. Background Art

[0002] As a key area for factory anti-corruption work, the safety importance of the gas station is self-evident. When the gas is produced from the gasifier, it is often mixed with a large amount of coal powder and water and has a high temperature. The function of the gas station air cooler is to cool and dust the gas, and it is one of the indispensable devices in the gas station process. The gasifier air cooler is a gas pipeline with upper and lower hollows. When the gas enters the gas chamber below the air cooler through the gas pipeline, it passes through several 3-8 meter pipelines during the rising process of the gas to cool and dust. In this process, the coal powder remaining in the gas will adhere to the surface of the air cooler pipeline and will naturally fall into the sump for a long time. The lower end of the air cooler needs to be sealed with a water seal, otherwise the gas will overflow and cause a safety accident. Therefore, the water level of the sump cannot be lower than the lower end of the air cooler; the long-term accumulation of coal powder will form a coal powder layer at the bottom of the sump, and the accumulation of the coal powder layer will also increase the water level in the sump. If the coal powder layer is higher than the lower pipe opening of the air cooler, the pipe opening will be blocked and the water in the sump will overflow. Regular cleaning of the coal powder layer and natural evaporation will cause the liquid level in the sump to drop, so it is necessary to check the liquid level of the sump frequently to ensure that the liquid level is not lower than the lowest water level of the lower pipe opening of the air cooler. If the water level is low, water needs to be added, and the water level cannot be higher than the highest water level of the sump.

[0003] In summary, the water level in the sump should be kept within a reasonable range of upper and lower limits. However, it is impossible for staff to stay on site for a long time to observe the water level in the sump. Traditional instruments for measuring liquid levels include capacitive level gauges, radar level gauges, and static pressure level gauges. However, the sump in a gas station contains a mixture of coal and water, and the natural environment is relatively harsh, so traditional level gauges are easily blocked in it. Utility Model Content

Through the above technical scheme, the pull-rope displacement sensor 7 is used to float on the water-adding layer 3 through the counterweight assembly 1 to monitor the height of the water-adding layer 3, and an alarm is issued when the water level is too high or too low, and the pull-rope displacement sensor 7 will not be affected by the harsh environment in the sump 2, and will not be blocked, thereby improving the accuracy of the measurement.

[0023] In this embodiment, the counterweight assembly 1 includes a lead sinker 101, which is fixedly mounted at the lower end of the pull rope 12. The upper end of the lead sinker 101 is connected to a float 108 through a connecting plate 105. The float 108 and the lead sinker 101 are fixedly mounted in a structure that can be quickly disassembled and installed. Specifically, an annular groove 102 and a notch 103 are provided on the lead sinker 101. There are two notches 103, and the positions are symmetrical about the axis of the lead sinker 101 and are connected to the annular groove 102. A support rod 106 is fixedly mounted at the lower end of the connecting plate 105. The support rod 106 is provided with two A clamping block 107 is fixedly installed at the lower end, and the clamping block 107 enters the annular groove 102 through the notch 103, and after rotation, the connecting plate 105 and the lead sinker 101 are clamped together. A clamping slot 104 is arranged on the upper side of the annular groove 102. During use, the lead sinker 101 will be pulled downward by gravity, and the float 108 provides buoyancy upward, so that the clamping block 107 is upward, and the lead sinker 101 drives the clamping slot 104 downward, and the clamping block 107 is stuck in the clamping slot 104 and will not fall off. The width of the clamping slot 104 can be set to be larger than the width of the clamping block 107, which is more convenient during installation.

[0024] In order to prevent the counterweight assembly 1 from shaking on the sump 2, in this embodiment, four limit bars 13 are installed on the gas chamber 6 and are located in the sump 2. The four limit bars 13 surround the float 108. The upper end of the limit bar 13 is fixed with a mounting cap 14. The gas chamber 6 is provided with a mounting hole 16. The limit bar 13 passes through the mounting hole 16. The mounting cap 14 is stuck in the mounting hole 16. The gas chamber 6 is provided with a threaded hole 15. After the mounting hole 16 and the mounting cap 14 are installed, the pull-wire displacement sensor 7 is installed. The pull-wire displacement sensor 7 can completely cover all the mounting caps 14 and be pressed. The pull-wire displacement sensor 7 is fixed to the gas chamber 6 through the cooperation of the fixing bolt 11 and the threaded hole 15.

[0025] The float 108 and the lead sinker 101 can cooperate with each other. The lead sinker 101 acts as a counterweight to pull downward, and the float 108 provides buoyancy to keep the whole balanced.

[0026] A scale 8 is provided on one side of the gas chamber 6 for recording the water level. A power line 9 and a data line 10 are connected to the pull-rope displacement sensor 7. The water level information is transmitted in real time through the power line 9 and the data line 10. If the water level is too high or too low, an alarm will be sounded. The counterweight assembly 1 floating in the sump will drop or rise accordingly. The pull-rope displacement sensor 7 will detect the corresponding data, and then transmit it to the DCS in the main control room through the data line 10, so as to monitor the water level at any time. The water level needs to be maintained at a reasonable upper and lower limit, so it is necessary to set the upper and lower limit alarm values. When the water level is lower than the minimum water level, an alarm will be sounded to remind the staff to add water in time; similarly, when the water level is higher than the maximum water level, an alarm will be sounded to remind the staff to add water in place or clean the coal powder layer at the bottom of the sump in time.
