Description

Technical Field

[0001] This utility model relates to the field of sealing test technology, specifically a sealing test device for a solid-liquid separator. Background Technology

[0002] A solid-liquid separator is a device that separates solid particles from liquids. It achieves effective separation of solids and liquids through physical principles such as gravity sedimentation, centrifugal force, and filtration. The sealing performance testing device for a solid-liquid separator is a specialized device used to test the sealing performance of the conveying pipeline of the solid-liquid separator. It mainly consists of a test chamber, a pressure control system, and a pressure sensor.

[0003] Existing pipe sealing test devices for solid-liquid separators typically involve directly connecting the solid-liquid separator pipe to the test chamber and connecting a seal to the other end. A certain pressure is then applied to the test chamber, and the sealing performance is tested by observing whether the pressure is stable. However, the structure is relatively simple, and the air pressure detection is greatly affected by temperature. It is difficult to detect whether the sealing performance of the pipe changes after the medium at different temperatures is delivered into the pipe, resulting in poor test results.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-4 A solid-liquid separator sealing performance testing device includes a base plate 1, an mounting plate 2 fixedly installed at the rear end of the base plate 1, a mounting plate 5 movably installed at the front end of the base plate 1 via a slider, a drive cylinder 3 installed at the rear end of the mounting plate 2, and a sealing fixing plate 4 installed at the end of the drive push rod of the drive cylinder 3.

[0024] See Figure 2 and Figure 3 Furthermore, the test piece 6 is fixedly installed at the rear end of the mounting plate 2 5 via a mounting bracket. The end of the test piece 6 near the drive cylinder 3 is fixedly connected to a drive cylinder 3 that is compatible with the sealing plate 1 4. A support frame is installed at the center of the top of the base plate 1. An electric telescopic rod 2 is installed inside the support frame. An arc-shaped support plate 9 is installed at the top of the push rod of the electric telescopic rod 2. A mica electric heating plate 10 is installed at the top of the arc-shaped support plate 9. A separator pipe 8 is installed at the top of the mica electric heating plate 10 and between the sealing plate 1 4 and the sealing plate 2 7. The top of the test piece 6 is connected to a gas supply pipe 13 and a liquid supply pipe 14 via connecting pipes. A solenoid valve 15 is installed at the connection between the gas supply pipe 13, the liquid supply pipe 14 and the connecting pipe. A pressure sensor 12 is installed on one side of the test piece 6. A pressure relief valve 18 is installed at the bottom of the test piece 6. An electric telescopic rod 11 is installed inside the base plate 1 near one side. The end of the push rod of the electric telescopic rod 11 is connected to the mounting plate 2 5.

[0025] Specifically, the separator pipe 8 can be placed on the top surface of the mica electric heating plate 10 as needed. Then, the drive cylinder 3 can be activated, and the push rod can be extended and retracted to drive the sealing fixing plate 4 to seal and fix the separator pipe 8, preventing gas leakage during the test. That is, by driving the push rod to extend and retract, the two sides of the separator pipe 8 are pushed to fit against the sealing fixing plate 7 and the sealing fixing plate 4 to complete the sealing and fixing process. After the separator pipe 8 is fixed, an external air pump can be connected to the air supply pipe 13 to pressurize and depressurize the air supplied in the separator pipe 8. At the same time, the pressure inside the test piece 6 can be detected through the pressure sensor 12. The sealing performance of the pipe can be judged based on the detection data. The pressure sensor 12 can be a high-sampling-rate sensor, such as the Honeywell PSM0001B42AN pressure sensor.

[0026] Example 2

[0027] See Figure 2 and Figure 4 Furthermore, based on Example 1, a rotary motor 16 is installed at the front end of the test piece 6, a metal seal is provided at the connection between the rotary motor 16 and the test piece 6, and an agitator 17 is connected to the end of the drive shaft of the rotary motor 16, with the agitator 17 extending into the interior of the separator pipe 8. A collection trough 19 is provided at the rear of the top of the bottom plate 1, and a drain pipe is connected to the lower side of one side of the collection trough 19. Sealing rubber plates are provided on the front and rear opposite surfaces of the sealing fixing plate 1 4 and the sealing fixing plate 2 7, and the center points of the sealing fixing plate 1 4, the separator pipe 8, and the sealing fixing plate 2 7 are on the same straight line.

[0028] Specifically, the pressure relief valve 18 can be used to release pressure and vent air. When testing the sealing performance of liquid media at different temperatures transported in the separator pipe 8, the external infusion pipe can be connected to the infusion pipe 14, and then the corresponding solenoid valve 15 can be opened to transport the liquid into the separator pipe 8. During the transport process, personnel can observe the liquid leakage at the separator pipe 8 to judge the sealing performance. During the liquid transport test, the liquid in the separator pipe 8 can be heated by energizing the mica electric heating plate 10 to test the sealing performance of liquids transported at different temperatures in the separator pipe 8. During the heating process, the rotary motor 16 can be started to drive the stirring rod 17 to rotate, thereby agitating the liquid and improving the heating uniformity. After heating, the stirring rod 17 can also be controlled to agitate the liquid to test the sealing performance of the liquid in the separator pipe 8 when it is stationary and when it is moving, thus improving the test effect. At the same time, during the gas transport test, the stirring rod 17 can also be controlled to rotate continuously in the separator pipe 8 to test the difference in data between the gas flow and the static state, so that personnel can make comparisons.

[0029] In actual operation, the separator pipe 8 can be placed on the top surface of the mica electric heating plate 10 as needed. Then, the drive cylinder 3 can be activated, and the push rod can be extended and retracted to drive the sealing fixing plate 4 to seal and fix the separator pipe 8, so as to prevent gas leakage during the test. That is, by driving the push rod to extend and retract through the drive cylinder 3, the two sides of the separator pipe 8 are pushed to fit with the sealing fixing plate 7 and the sealing fixing plate 4 to complete the sealing and fixing process. After the separator pipe 8 is fixed, the external air pump can be connected to the air supply pipe 13 to pressurize and depressurize the air supply in the separator pipe 8. At the same time, the pressure inside the test piece 6 can be detected through the pressure sensor 12. The sealing performance of the pipe can be judged based on the detection data.

[0030] Pressure relief valve 18 can be used for pressure relief and venting. When testing the sealing performance of liquid media at different temperatures transported in separator pipe 8, an external infusion pipe can be connected to infusion pipe 14, and then the corresponding solenoid valve 15 can be opened to transport liquid into separator pipe 8. During the transport process, personnel can observe the liquid leakage at separator pipe 8 to judge the sealing performance. During the liquid transport test, the liquid in separator pipe 8 can be heated by energizing mica electric heating plate 10 to test the sealing performance of liquids transported at different temperatures in separator pipe 8. During the heating process, rotary motor 16 can be started to rotate the liquid. The method of rotating the stirring rod 17 driven by 16 can agitate the liquid to improve the uniformity of heating. After heating, the stirring rod 17 can also be controlled to agitate the liquid to test the sealing performance of the liquid in the separator pipe 8 when it is stationary and when it is moving, thus improving the test results. During the gas delivery test, the stirring rod 17 can also be controlled to rotate continuously in the separator pipe 8 to test the difference in data between the gas flow and when it is stationary, so that personnel can make comparisons. After the test, the drive push rod of the drive cylinder 3 can be controlled to retract to release the obstruction at one end of the separator pipe 8, so that the liquid in the separator pipe 8 can be discharged into the collection tank 19 and subsequently discharged through the collection tank 19.

[0031] Furthermore, the display and control components and modules used in the aforementioned drive cylinder 3, solenoid valve 15, pressure sensor 12, rotary motor 16, and pressure relief valve 18 are all existing technologies, which can be fully implemented by those skilled in the art.
