Embodiment 1
[0049] This embodiment provides a static pressure measurement device, including a pressure measurement sensor 16 and a probe lead wire 11, and also includes a lead pipe 2, a probe sleeve 15, a flexible sealing ring 18 and a flexible sealing sleeve 17;
[0050] The probe sleeve 15 and the extraction tube 2 are both circular tube structures, and the top end of the probe sleeve 15 is detachably connected to the bottom end of the extraction tube 2; it is preferable to design the top end of the probe sleeve 15 and the bottom end of the extraction tube 2 to be sealedly connected through the connector 10 , the connecting piece 10 adopts a threaded structure and a sealing ring, so as to realize the threaded sealing connection between the probe sleeve 15 and the lead-out pipe 2 .
[0051] The top port of the probe sleeve 15 is completely covered with the probe sealing plate; the outer wall of the pressure measurement sensor 16 is sleeved with a flexible sealing ring 18; The sealing sle...
Embodiment 2
[0056] This embodiment provides a resin particle layered liquid level measurement device, which is characterized in that it includes a liquid level gauge 3, an arithmetic unit and a display, and the static pressure measurement device provided in Embodiment 1; the liquid level gauge 3 is used for measuring And output the height of the upper cavity of the liquid surface in the storage tank; the static pressure measuring device is used to measure and output the static pressure at the bottom of the storage tank; the bottom end of the lead-out pipe 2 extends into the storage tank to ensure that the probe sleeve 15 is placed in the storage tank inner bottom.
[0057] The signal output terminals of the liquid level gauge 3 and the static pressure measuring device are connected to the input terminal of the calculator; the calculator is used to receive the height of the upper cavity of the liquid surface in the storage tank, the static pressure of the bottom of the storage tank, and com...
Embodiment 3
[0060] This embodiment provides a method for measuring the layered liquid level of resin particles, using a device for measuring the layered liquid level of resin particles provided in Example 2. The specific operation steps are as follows:
[0061] S1. Install a liquid level gauge at the top of the storage tank, and install a static pressure measurement device at the bottom of the storage tank;
[0062] S2. Input the waste resin into the storage tank and let it stand for stratification;
[0063] S3. Measure and output the height of the cavity above the liquid surface in the storage tank by the liquid level gauge;
[0064] S5. Measure and output the static pressure at the bottom of the storage tank through a static pressure measuring device;
[0065] S6. Receive the height of the upper cavity of the liquid surface in the storage tank and the static pressure of the bottom of the storage tank, and combine the structural parameters of the storage tank and the performance paramet...
