Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of weighing, in particular to a continuous weighing device under adjustable air pressure. Background Art
[0002] A weighing sensor is actually a device that converts mass signals into measurable electrical signals. When using a sensor, you should first consider the actual working environment of the sensor. This is crucial to the correct selection of a weighing sensor, as it affects whether the sensor can work properly, its safety and service life, and even the reliability and safety of the entire weighing instrument.
[0003] When controlling quicksand in a river, it is necessary to know the specific data of the sand content in the river. The traditional detection process is to separate the sand and water after sampling, and then measure the weight of the sand and water respectively. Since the detection process is mostly carried out indoors, leakage may occur during the transportation of samples, resulting in slight changes in the detection data. In addition, during the detection, the separation process will also cause sand abrasion and water evaporation. Therefore, there is a lack of equipment that can directly detect the sand content of samples.
[0004] Based on this, a continuous weighing device under adjustable air pressure is proposed. Utility Model Content
[0005] The purpose of the utility model is to solve the above problems and to provide a continuous weighing device under adjustable air pressure.

[0014] 1. This application adopts a weighing sensor, which can detect the weight of the sand in the sample in real time. It cooperates with the air pressure controller to ensure that the air pressure in the detection environment remains unchanged, thereby improving the detection accuracy. At the same time, since the sample is directly weighed and tested, various detection errors that may occur during the separation process are avoided, thereby improving the detection efficiency.

[0024] Specifically, Figure 2 As shown, a fixed plate 14 is connected to the chassis 1, and the fixed plate 14 is connected to a connecting plate 16 through a support frame 15. A weighing sensor 17 is fixedly connected to the connecting plate 16. By providing the support frame 15, the interference of overflow water on the detection process is reduced, and the detection accuracy is improved.
[0025] Specifically, Figure 2 As shown, the conduit 7 is connected to the sealing cover 3 and a sealing ring 9 is provided, and the conduit 7 is connected to a flow meter 8. By providing the sealing ring 9, the sealing performance of the structure is improved, and the detection accuracy is correspondingly improved.
[0026] Specifically, Figure 2 As shown, the detection mechanism includes a foam column 20, a slide bar 18 is connected to the chassis 1, the foam column 20 is slidably mounted on the slide bar 18, a fixed column 19 is connected to the slide bar 18, the fixed column 19 serves to support the foam column 20, a laser head 21 is connected inside the slide bar 18, and a receiving alarm 22 is connected to the inner wall of the transparent cover 2. In the initial state, the laser head 21 will emit a laser signal to the receiving alarm 22, and it is in an unalerted state at this time.
[0027] Specifically, Figure 2As shown, a drain pipe 6 is connected to the outside of the chassis 1, a drain valve 4 and a flow meter 5 are connected to the drain pipe 6, and one end of the drain pipe 6 passes through the chassis 1 and is connected to the upper end of the chassis 1.
[0028] Specifically, Figure 2 As shown, the sealing cover 3 is connected to an air pipe 10, and the other end of the air pipe 10 is connected to an air pressure controller 11. The air pressure controller 11 can detect the pressure in the pressure chamber in real time and adjust the internal air pressure to ensure that the pressure of the detection environment remains unchanged.
[0029] In summary, the present embodiment provides a continuous weighing device under adjustable air pressure. When it is necessary to weigh the weight of sand in water under different pressures, first fill the filter cup holder 12 with water until it flows out from the overflow pipe 13, set the air pressure value of the air pressure controller 11 to ensure that the air pressure in the device remains unchanged when water and sand are injected into the device, so as to avoid interfering with the weighing operation of the weighing sensor 17, and then inject the water mixed with sand into the filter cup holder 12 through the conduit 7, and understand the flow rate of the injected water through the flow meter 8. When the sand enters the filter cup holder 12, the sand will undergo multi-stage filtration to ensure that the sand can completely stay in the filter cup holder 12, and the excess water will flow into the bottom of the device from the overflow pipe 13. At this time, the sand in the filter cup holder 12 gradually increases, and the water at the bottom of the device will also increase. At this time, the water at the bottom of the device will push the foam column 20 to float up along the slide bar 18. When the foam column 20 blocks the laser head 21, the receiving alarm 22 cannot receive the laser signal. At this time The receiving alarm 22 starts to sound an alarm, warning the detection personnel that the water level inside the device has reached the warning value and it is necessary to stop injecting water and sand. The weighing sensor 17 installed in the device can detect the weight change of the filter cup holder 12 in real time. After the detection is completed, the water in the device is discharged through the drain valve 4, and the volume of the discharged water is known through the flow meter 15. The weight of the sand in the water under the air pressure can be known by converting the weighing data before and after the weighing of the weighing sensor 17 and the data changes on the flow meter 15 and the flow meter 2 8. Since the internal water is in an overflow state when the filter cup holder 12 is measured before and after, the specific conversion is the flow meter 15 data minus the flow meter 2 8 data, which is the volume of the water discharged from the filter cup holder 12 by the sand. This value is converted into the weight of water, plus the data of the change of the data before and after the measurement of the weighing sensor 17, which is the weight of the sand in the water injection, divided by the flow data of the flow meter 2 8, which is the sand content data of the sample, providing strong data support for understanding the sand content in the water of the sample.
