Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0029] See also Figure 1-Figure 3 As shown, this embodiment is a new type of liquid level gauge diaphragm cleaner, comprising:

[0030] The diaphragm cleaning assembly includes a cleaner 11, a cleaning tank 12, a flushing nozzle 14, a scraper 15, a cylinder 16, and a heating coil 19; the cleaning tank 12 is opened at the center of the top of the cleaner 11, the flushing nozzle 14 passes through and is fixed inside one end of the cleaner 11, the scraper 15 is located on one side of the cleaning tank 12, the cylinder 16 is fixed to one end outside the cleaner 11, and the heating coil 19 is placed inside the cleaner 11;

[0031] The cleaner 11 is used to open the cleaning tank 12, and the cleaning tank 12 is used to place the diaphragm to be cleaned. The flushing pipe mouth 14 is used to connect high-pressure flushing water, and the pneumatic switch ball valve is set to a program. The pneumatic switch valve is opened for flushing for 30 seconds every 30 minutes. Frequent flushing ensures that the level gauge diaphragm is clean. The scraper 15 is used to scrape off the viscous material on the surface of the diaphragm. The cylinder 16 is used to drive the scraper 15. The heating coil 19 is used for materials that will agglomerate and crystallize on the diaphragm at low temperature. The material on the level gauge diaphragm can be powered on to heat to about 150°C to melt the material and eliminate the influence of material agglomeration and crystallization on the level gauge measurement.

[0032] One end of the cylinder 16 is slidably connected to a piston rod 161, one end of the piston rod 161 passes through and is slidably connected to the inside of one end of the cleaner 11, one end of the piston rod 161 is fixedly connected to one side of the scraper 15, and the scraper 15 moves through the piston rod 161 and the cylinder 16;

[0033] An annular plate 13 is rotatably connected to the bottom end of the cleaning tank 12;

[0034] The cylinder 16 drives the piston rod 161, and the piston rod 161 is fixedly connected to the scraper 15. When the cylinder 16 is started, the piston rod 161 pushes the scraper 15 to move, so that the scraper 15 scrapes off the viscous material on the surface of the diaphragm. The annular plate 13 is used to place the diaphragm to be cleaned.

[0035] A heating groove 18 is provided at the location where the heating coil 19 is placed with the cleaner 11. The other end of the cleaner 11 is fixedly connected to an electric heating controller 17. The heating coil 19 is electrically connected to the electric heating controller 17.

[0036] The cleaning tank 12 is connected to the flushing pipe opening 14;

[0037] The heating tank 18 is used to place the heating coil 19 , and the electric heating controller 17 is used to control the opening and closing of the heating coil 19 .

[0038] Working principle: When the component is not in use, the flushing nozzle 14 is not connected to the high-pressure flushing water. When the component is in use, the flushing nozzle 14 is connected to the high-pressure flushing water, and then the diaphragm to be cleaned is placed on the annular plate 13 in the cleaning tank 12, and then the high-pressure flushing water enters the cleaning tank 12 through the flushing nozzle 14. Since the flushing nozzle 14 is externally equipped with a pneumatic switch ball valve setting program, the pneumatic switch valve is opened for flushing for 30 seconds every 30 minutes, and frequent flushing is performed to ensure that the level gauge diaphragm is clean. During this process, the cylinder 16 and the electric heating controller 17 are started, and the cylinder 16 pushes the scraper 15 to move through the piston rod 161, so that the scraper 15 scrapes off the viscous material on the surface of the diaphragm. The electric heating controller 17 controls the heating coil 19 to heat, thereby heating the material on the level gauge diaphragm to about 150°C, melting the material, and then facilitating the scraper 15 to scrape off the viscous material on the diaphragm.

[0039] In the above steps, the membrane is cleaned by flushing with water, heating coil 19 and scraper 15.

[0040] See also Figure 1 、 Figure 3-Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0041] Auxiliary cleaning components;

[0042] The auxiliary cleaning assembly includes a set of fixed rods 21, fixed plates 22, slots 23 and sliders 24; the fixed rods 21 are fixed to the bottom end of the cleaner 11, the fixed plates 22 are fixed between the bottom ends of the fixed rods 21, the slots 23 are opened at the center of the top of the fixed plates 22, and the sliders 24 are slidably connected to the inside of the slots 23;

[0043] The fixing rods 21 are used for connecting the fixing plates 22 . There are four fixing rods 21 in total. The fixing plates 22 are used for opening the slots 23 . The slots 23 are used for connecting and moving the sliders 24 . The sliders 24 are used for connecting the vertical rods 25 .

[0044] The top of the slider 24 is fixedly connected to a vertical rod 25, the top of the vertical rod 25 is fixed to a cleaning plate 26, and the top of the cleaning plate 26 is fixedly connected to a friction block 28;

[0045] The vertical rod 25 is used for connecting the cleaning plate 26 , and the cleaning plate 26 and the friction block 28 are used for cleaning the viscous material at the bottom end of the scraper 15 .

[0046] Connection holes 27 are opened on both sides of the annular plate 13, and the cleaning plate 26 and the friction block 28 are clamped with the connection holes 27. The bottom end of the cleaning plate 26 is fixedly connected with a sealing gasket 29, which fits the bottom end of the annular plate 13;

[0047] The connecting hole 27 is used for placing the cleaning plate 26 and the friction block 28, and for moving the vertical rod 25. The sealing gasket 29 is used to seal the connection between the cleaning plate 26 and the bottom end of the annular plate 13; when the scraper 15 cleans the bottom end, the annular plate 13 is rotated so that the annular plate 13 drives the connecting hole 27 to rotate from a horizontal state on the same level to a vertical state, which can push the vertical rod 25 to drive the cleaning plate 26 and the friction block 28 to move along the direction of the connecting hole 27.

[0048] Working principle: when the component is not in use, the scraper 15 is located at one side of the cleaning tank 12, the connecting hole 27 is in a horizontal state, and the cleaning plate 26 and the friction block 28 are located in the connecting hole 27; after the diaphragm is cleaned, the cylinder 16 pushes the scraper 15 to move to the middle of the annular plate 13 through the piston rod 161, and then the annular plate 13 is rotated by hand, so that the annular plate 13 drives the connecting hole 27 to rotate from the horizontal state on the same level to the vertical state, and then the vertical rod 25 is pushed by hand, and the thrust pushes the slider 24 to move in the slot 23 through the vertical rod 25, so that the vertical rod 25 drives the cleaning plate 26 and the friction block 28 to move along the direction of the connecting hole 27 through the slider 24. Since the friction block 28 is in contact with the bottom end of the scraper 15, the friction block 28 scrapes and cleans the viscous matter at the bottom end of the scraper 15 during the movement to prevent the viscous matter from adhering to the scraper 15. After the scraper 15 is cleaned, the friction block 28 is flushed with water to flush away the cleaning matter on the friction block 28;
