[0028] The structural features of the present invention are now described in detail with reference to the accompanying drawings.
[0029] Example 1
[0030] See also Figure 1-Figure 4 , an integrated device with automatic cleaning tuning fork density meter during line stop, comprising a docking flange 1 and a density meter instrument 2, the docking flange 1 is used to connect the density meter instrument 2 to the production pipeline, a flange pipe 11 for connecting the density meter instrument 2 is fixedly provided on the docking flange 1, a tuning fork rod 21 of the density meter instrument 2 passes through the flange pipe 11, so that the tuning fork terminal 22 extends into the production pipeline, a cleaning jacket 3 is connected to the flange pipe 11, the tuning fork rod 21 is fixed to the top of the cleaning jacket 3, so that the tuning fork rod 21 and the cleaning jacket 3 form an integrated structure, a water inlet pipe 31 is provided on one side of the cleaning jacket 3, a water inlet solenoid valve 32 is connected to the water inlet pipe 31, and the water inlet solenoid valve 32 is connected to the controller, after the line is stopped, the water inlet solenoid valve 32 is started to clean the tuning fork terminal 22, and the cleaning time can be set according to different media, so that a better line stop cleaning operation can be completed to prevent the viscous material in the pipeline from solidifying on the surface of the tuning fork terminal.
[0031] In order to make the cleaning of the tuning fork terminal 22 more comprehensive, a water distribution ring 4 communicated with the cleaning jacket 3 is provided inside the flange tube 11, and the water distribution ring 4 can evenly distribute the cleaning water. The water distribution ring 4 is sleeved on the tuning fork rod 21 and movably connected in the flange tube 11, wherein the inner ring of the water distribution ring 4 has the same outer diameter as the tuning fork rod 21, and the outer ring of the water distribution ring 4 has the same inner diameter as the flange tube 11, and the water distribution ring 4 can slide on the tuning fork rod 21. The water distribution ring 4 is a hollow structure, and a water inlet hole 41 is provided on the top. The water inlet hole 41 is provided with a self-sealing component, and the self-sealing component includes a sealing gasket 42 and a tension spring 5. The sealing gasket 42 is fixed on the top of the flange tube 11 for sealing the water inlet hole 41. The tension spring 5 is fixedly arranged in the cleaning jacket 3 for pulling the water distribution ring 4. When in the non-cleaning state, under the action of the tension spring 5, the water distribution ring The water inlet hole 41 at the top of the water ring 4 fits tightly on the sealing gasket 42, which plays a sealing role of the water inlet hole 41. In the cleaning state, the incoming water generates a downward pressure on the water distribution ring 4, and this pressure is greater than the tension of the tension spring 5. At this time, the water distribution ring 4 will move downward. At this time, the water inlet hole 41 loses its sealing effect, and the cleaning water enters the water distribution ring 4 from the water inlet hole 41. After cleaning, the water distribution ring 4 rises again under the action of the tension spring 5, sealing the water inlet hole 41, thereby realizing the self-sealing of the water inlet hole 41. In order to limit the downward movement distance of the water distribution ring 4, a limit block 23 is fixedly provided on the tuning fork rod 21 and below the water distribution ring 4. Specifically: by setting a self-sealing component, the cleaning jacket is in a fully closed state in the non-stop line state, which can prevent the medium in the pipeline from flowing back to the cleaning jacket 3 to cause blockage.
[0032] The bottom of the water distribution ring 4 is provided with a cleaning assembly for cleaning the tuning fork terminal 22. The cleaning hole cleaning assembly includes a plurality of cleaning pipes 6. The plurality of cleaning pipes 6 are partially on the water distribution ring 4. One end of the cleaning pipe 6 extends to the outside of the docking flange 1. The water distribution ring 4 can evenly distribute the incoming water to each cleaning pipe 6. The setting of the self-sealing assembly can also seal some cleaning liquid in the cleaning pipe 6 to prevent the medium in the pipeline from entering the cleaning assembly and causing blockage. A cleaning hole 8 is provided on one side of the cleaning pipe 6 corresponding to the tuning fork terminal 22. The cleaning holes 8 arranged around the tuning fork terminal 22 can better complete the cleaning function. The cleaning holes 8 are opened obliquely upward so that the cleaning holes 8 spray water obliquely upward. The water sprayed obliquely upward can form a thrust downward to assist the pressure of the water flow to push the water distribution ring 4 downward. On the other hand, the water sprayed obliquely upward from the cleaning hole 8 can better tilt the viscous material inside the tuning fork terminal 22 to avoid the residue of viscous material and make it clearer and more thorough.
[0033] The integrated device of the tuning fork density meter with automatic line stop cleaning of the present invention has a simple structure, can complete the line stop cleaning of the tuning fork terminal 22, has an automatic water shut-off structure, can prevent backflow during the production process, and can automatically clean the tuning fork terminal 22 of the tuning fork density meter in situ when the line is stopped, which can effectively prevent viscous substances from solidifying on the surface of the tuning fork terminal 22, and can effectively ensure the detection accuracy of the tuning fork density meter.
[0034] Specifically, during use, by setting a water inlet solenoid valve 32 on the water inlet pipe 31, when the line is stopped for maintenance, the water inlet solenoid valve 32 is started, and the incoming water pushes the water distribution ring 4 to move downward, so that a passage is formed between the cleaning jacket 3 and the water distribution ring 4, and the incoming water is evenly distributed to each cleaning pipe 6 through the water distribution ring 4, and is obliquely sprayed upward from the cleaning hole 8 on one side of the bottom of the cleaning pipe 6 onto the tuning fork terminal 22, thereby completing the cleaning of the tuning fork terminal 22. The cleaning time can be set according to different media to achieve the line stop cleaning operation and avoid the viscous material in the pipeline from solidifying on the surface of the tuning fork terminal 22. After the cleaning is completed, the water distribution ring 4 rises again under the action of the tension spring 5, and seals the water inlet hole 41, so that the cleaning jacket 3 is in a fully closed state again, which can avoid the medium in the pipeline from flowing back into the cleaning jacket 3 to cause clogging. The setting of the self-sealing component can also seal some cleaning liquid in the cleaning component to avoid the medium in the pipeline from entering the cleaning component to cause clogging of the cleaning hole.
[0035] Example 2
[0036] Reference Figure 5-Figure 6 As another preferred embodiment of the present invention, the difference from Embodiment 1 is that the cleaning component includes a cleaning sleeve 7, which is connected to the water distribution ring 4. A limit block 23 is fixedly provided on the tuning fork rod 21 and located below the water distribution ring 4. The setting of the limit block 23 can limit the cleaning sleeve 7 to move down to the position of the tuning fork terminal 22. The cleaning sleeve 7 is provided with a cleaning hole 8 at the position corresponding to the tuning fork terminal. The length of the cleaning sleeve 7 is not greater than the flange pipe 11. During cleaning, the cleaning sleeve 7 moves downward to the position of the tuning fork terminal 22 under the drive of water pressure, and the cleaning hole 8 is opened obliquely upward, so that the cleaning hole 8 sprays water obliquely upward. By setting a downwardly movable cleaning sleeve 7, when the line is not stopped, the cleaning sleeve 7 can be retracted into the flange tube 11 and away from the tuning fork terminal 22, so as not to hinder the flow of the medium in the pipeline and not interfere with the detection of the tuning fork terminal 22. When the line is stopped for cleaning, the cleaning sleeve 7 will be moved downward by the push of the water flow and will be sleeved on the outside of the tuning fork terminal 22 to clean the tuning fork terminal 22. After cleaning, the cleaning sleeve will be retracted into the flange tube 11 under the action of the self-sealing component.
