Description

Technical Field

[0001] The utility model relates to the technical field of vibration densitometers, in particular to an explosion-proof single-tube online vibration densitometer. Background Art

[0002] A vibration densitometer is an instrument that has a built-in measuring pipe. When the tested liquid passes through the pipe, different liquids have different masses, and the volume inside the pipe is constant. What affects the mass is the density. Changes in density will cause changes in the vibration frequency of the pipe, thereby measuring the density or concentration of the liquid in the pipe.

[0003] However, it still has the following disadvantages in actual use:

[0004] When using an existing single-tube online vibration density meter, due to different measurement objects, it is necessary to detect the density of a solid-liquid mixed object or a liquid object. When it is necessary to detect a single liquid object and there is no need to detect the solid substance, the solid cannot be separated from the liquid object, and after the solid-liquid object detection is completed, the solid substance will remain inside the vibration tube, which is not convenient for the next detection.

[0005] Therefore, a new explosion-proof single-tube online vibration density meter is proposed to solve the above problems. Utility Model Content

[0036] Example 1

[0037] See also Figure 1-3 As shown, this embodiment is an explosion-proof single-tube online vibration density meter, comprising:

[0038] The density meter assembly 1 includes an outer sleeve 11;

[0039] The movable assembly 2 comprises a joint 21 fixedly connected to both ends of the outer sleeve 11, a hollow groove 22 opened in the inner position of the joint 21, a movable plate 23 slidably connected to the inner position of the joint 21, a baffle 24 fixedly connected to both ends of the movable plate 23, a sealing block 25 fixedly connected to the central position of the outer surface of the movable plate 23, a through hole 26 fixedly connected to one side of the outer surface of the movable plate 23, and a filter screen 27 fixedly connected to the other side of the outer surface of the movable plate 23;

[0040] The joint 21 is used to be connected to the pipe of the measured object, the hollow groove 22 is used to place the movable plate 23, the movable plate 23 is used to carry the sealing block 25 and the filter screen 27 respectively, the baffle 24 is used to limit the two ends of the movable plate 23, the sealing block 25 is used to close the connecting port, the filter screen 27 is used to close the connecting port, and the through hole 26 is used to connect the connecting port and the vibration tube 13;

[0041] The densitometer assembly 1 further comprises a display 12 fixedly connected to the upper end position of the outer surface of the outer sleeve 11 and a vibration tube 13 placed at the central position inside the outer sleeve 11;

[0042] The display 12 is used to observe the measured density, and the vibration tube 13 is used to vibrate the object to be measured;

[0043] The hollow groove 22 is opened relative to the movable plate 23, and the baffles 24 are located on both sides of the joint 21;

[0044] The movable plate 23 can move inside the hollow groove 22, and the baffle 24 prevents the movable plate 23 from moving out of the hollow groove 22;

[0045] The baffle plate 24 and the movable plate 23 are vertical structures, and the through hole 26 is connected to the inside of the vibration tube 13;

[0046] By moving the movable plate 23, the movable plate 23 drives the through hole 26 and the outer end of the vibration tube 13 to correspond, so that the solid and liquid objects can be detected;

[0047] The sealing block 25, the through hole 26 and the filter screen 27 are located outside the vibration tube 13, and a communication port is provided in the center of the joint 21;

[0048] The connecting port can be sealed by the sealing block 25 to seal the inside of the vibration tube 13;

[0049] Working principle: When the density of solid or liquid objects needs to be tested, the movable plate 23 is moved so that the movable plate 23 moves inside the hollow groove 22, and drives the through hole 26 to correspond to the connecting port at the central position inside the joint 21, and the solid or liquid objects can enter the vibration tube 13 through the through hole 26;

[0050] When the density of a liquid object needs to be detected, the movable plate 23 is moved so that the movable plate 23 moves inside the hollow groove 22 and drives the filter screen 27 to correspond to the communication port at the central position inside the joint 21. The liquid object can enter the vibration tube 13 through the filter screen 27, and the solid object will not enter the vibration tube 13.

[0051] When the vibration tube 13 is not used for detection, the movable plate 23 is moved so that the movable plate 23 moves inside the hollow groove 22, and drives the sealing block 25 to correspond to the connecting port at the central position inside the joint 21, so that both ends of the connecting port are closed by the sealing block 25, thereby preventing impurities from entering the vibration tube 13 and affecting the next detection.

[0052] Example 2

[0053] See also Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0054] The explosion-proof component 3 is fixedly connected to the inner position of the outer sleeve 11;

[0055] The explosion-proof component 3 is used to protect the vibration tube 13 from bursting;

[0056] The explosion-proof assembly 3 includes a first hollow circular groove 31 formed on the inner wall of the outer sleeve 11, a pressure sensor 32 fixedly connected to the inner end surface of the first hollow circular groove 31, a telescopic spring 33 fixedly connected to the outer surface of the pressure sensor 32, a protective block 34 fixedly connected to the outer end of the telescopic spring 33, and a second hollow circular groove 35 formed on the outer surface of the protective block 34;

[0057] The first hollow circular groove 31 is used to fix the pressure sensor 32 and the telescopic spring 33, the second hollow circular groove 35 is used to fix the telescopic spring 33, the pressure sensor 32 is used to measure the elastic force of the telescopic spring 33, and the protection block 34 is used to protect the outer sleeve 11;

[0058] The protection block 34 is a circular structure composed of four groups of arc-shaped structures, and the protection block 34 is located outside the vibration tube 13;

[0059] When the vibration tube 13 bursts, it splashes outwards and directly contacts the protection block 34, exerting an outward impact force on the protection block 34;

[0060] Working principle: When the vibration tube 13 bursts, the fragments of the vibration tube 13 splash outward, thereby applying an outward impact force to the protective block 34. The protective block 34 moves outward, driving the telescopic spring 33 to be compressed. The telescopic spring 33 is compressed to generate elastic force. The pressure sensor 32 measures the elastic force of the telescopic spring 33, and the telescopic spring 33 applies an inward force to the protective block 34, thereby weakening the burst impact of the vibration tube 13. At the same time, the pressure sensor 32 prompts the outside world that the vibration tube 13 bursts, and the measured density result is inaccurate and needs to be remeasured.
