Description

Technical Field

[0001] The invention relates to the technical field of liquid level meters, and in particular to a high-precision intelligent liquid level meter. Background Art

[0002] Smart level meter is a device used to measure the height of liquid or solid materials, usually with the characteristics of automation, digitization and intelligence; it is widely used in petroleum, chemical, water treatment, food and beverage and other industries, and can monitor the liquid level changes in real time and transmit the data to the control system or monitoring platform; smart level meter adopts advanced sensing technology, can achieve millimeter level or even higher measurement accuracy, supports wireless or wired communication, can transmit data to the remote monitoring system in real time, and can adopt various measurement principles such as ultrasonic, radar, capacitance, float, etc. according to different application scenarios;

[0003] A float-type liquid level gauge is a common intelligent liquid level gauge. It usually includes a flange, a detection guide rod and a detection dial installed on the flange. A float ball is inserted through the detection guide rod. A magnet is fixed inside the float ball. A sensor is installed inside the detection dial. When the liquid level changes, the position of the magnet also changes. This position change will be detected by the sensor installed on the housing and converted into an electrical signal through an electromagnetic signal, and then the liquid level signal is output. It has high accuracy and reliability.

[0004] However, the existing electromagnetic high-precision intelligent liquid level meter still has the following defects in actual use:

[0005] When the high-precision intelligent liquid level meter is installed in the reactor to detect the liquid level in the reactor, the reactants in the reactor will adhere to the outside of the detection guide rod and the lower surface of the float. When the reactants adhere to the outer wall of the detection guide rod and contact the float, the friction between the float and the detection guide rod will increase, and the displacement resistance of the float along the detection guide rod will increase. The reactants adhere to the lower surface of the float and increase the weight of the float, thereby reducing the buoyancy of the float, which will reduce the detection accuracy. Therefore, the high-precision intelligent liquid level meter needs to be disassembled regularly to clean the detection guide rod and the float, which is troublesome.

[0040] A limit block 14 is installed at the bottom of the detection guide rod 11, and a mounting plate 15 is movably sleeved on the outer side of the detection guide rod 11. A mounting block 19 sleeved on the outside of the detection guide rod 11 is rotatably installed on the mounting plate 15, and a cleaning mechanism 2 acting on the detection guide rod 11 is installed on the mounting block 19. A spiral groove 111 is opened on the outer wall of the detection guide rod 11, and a guide rod 191 extending into the spiral groove 111 is fixedly installed on the inner wall of the mounting block 19. In this embodiment, the end ball of the guide rod 191 is connected with a ball bearing that fits the inner wall of the spiral groove 111, which is conducive to the smooth displacement of the guide rod 191 along the spiral groove 111. An annular block 16 sleeved on the outside of the detection guide rod 11 is rotatably installed at the bottom of the flange 1, and lifting mechanisms 17 connected to the mounting plate 15 are symmetrically installed at the bottom of the annular block 16. The mounting plate 15 is slidably displaced along the detection guide rod 11 through the two lifting mechanisms 17, so as to form a cleaning mechanism 2 for cleaning the outer wall attachments of the detection guide rod 11;

[0041] An electromagnet 18 sleeved on the outside of the detection guide rod 11 is fixedly installed at the bottom of the flange 1, and a driving mechanism 3 for driving the annular block 16 to rotate is installed at the bottom of the flange 1.

[0042] When in use, the high-precision intelligent liquid level gauge is installed on the reactor through the flange 1, so that the detection guide rod 11 extends to the inside of the reactor. When the liquid level in the reactor rises or falls, the floating ball 13 moves along the detection guide rod 11, driving the magnet in the floating ball 13 to move, and the sensor in the detection dial 12 detects the change in the position of the magnet, converts the electromagnetic signal into an electrical signal, and then outputs a liquid level signal; when cleaning the attachments on the outer wall of the detection guide rod 11, the cleaning mechanism 2 is brought into contact with the outer wall of the detection guide rod 11 and the inner wall of the spiral groove 111, and the mounting plate 15 is slid upward along the detection guide rod 11 through two lifting mechanisms 17, driving the mounting block 19 to move along the detection guide rod 11.

At this time, the electromagnet 18 is controlled to be turned on, and the electromagnet 18 is magnetically attracted to the magnet inside the floating ball 13, so that the floating ball 13 is positioned. At this time, the mounting block 19 is clamped with the annular block 16 through the clamping assembly 4, so that the cleaning mechanism 2 contacts the bottom of the floating ball 13, and then the annular block 16 is rotated at the bottom of the flange 1 through the driving mechanism 3, so as to drive the cleaning mechanism 2 to rotate around the detection guide rod 11, and the bottom of the floating ball 13 can be cleaned by the cleaning mechanism 2, so that there is no need to disassemble the high-precision intelligent liquid level meter and then clean the attachments on the detection guide rod 11 and the floating ball 13, which is more convenient.

Conversely, the control motor 175 drives the winding shaft 172 to rotate in the opposite direction on the support frame 171, so that the pull rope 173 wound on the outside of the winding shaft 172 can be unfolded, so that the gravity force of the mounting plate 15 and the mounting block 19 and the parts installed on the mounting block 19 can make the mounting plate 15 slide along the detection guide rod 11 away from the flange 1.

[0044] In this embodiment, the driving mechanism 3 includes an inner gear ring 31, a motor 32 and a spur gear 33. The inner side wall of the annular block 16 is coaxially fixed with the inner gear ring 31. The bottom of the flange 1 and the inner side of the annular block 16 are fixedly installed with a motor 32. The output shaft of the motor 32 is coaxially fixed with the spur gear 33 meshing with the inner gear ring 31. When in use, the motor 32 is controlled to be turned on, and the output shaft of the motor 32 rotates to drive the spur gear 33 to rotate, thereby driving the annular block 16 to rotate at the bottom of the flange 1 through the inner gear ring 31, which is convenient for control.
