[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Please refer to the attached Figure 1 To the attached Figure 3 This embodiment provides a disturbance-proof dynamic and static pressure level gauge for a kitchen slurry tank, characterized by comprising a measuring mechanism 1, a pressure-guiding mechanism 2, and a protective mechanism 3. The pressure-guiding mechanism 2 comprises a pressure-guiding tube 21 extending through the tank wall. The measuring mechanism 1 is connected to the pressure-guiding tube 21 outside the tank. The protective mechanism 3 comprises a protective sleeve 31 and a protective baffle 32 disposed within the tank. The protective sleeve 31 surrounds an end of the pressure-guiding tube 21 away from the measuring mechanism 1 and is used to block dynamic pressure generated by the fluid around the axial direction of the tank. The protective baffle 32 is disposed on a side of the protective sleeve 31 away from the pressure-guiding tube 21 and is used to block dynamic pressure generated by the fluid along the radial direction of the tank. The static pressure level gauge for the kitchen slurry tank of this embodiment is provided with a measuring mechanism 1 and a pressure-guiding mechanism 2, and a protective mechanism 3 arranged inside the tank body is used to surround and protect the part of the pressure-guiding tube 21 of the pressure-guiding mechanism 2 extending into the tank body, wherein the protective mechanism 3 includes a protective sleeve 31 and a protective baffle 32. When the slurry tank is stirring, the flowing slurry will mainly exert dynamic pressure interference around the axial direction of the tank body and dynamic pressure interference along the radial direction of the tank body on the pressure-guiding tube 21. The protective sleeve 31 is arranged around the part of the pressure-guiding tube 21 located inside the tank body, which can block and weaken the dynamic pressure interference around the axial direction of the tank body. The protective baffle 32 is covered on one side of the protective sleeve, which can block and weaken the dynamic pressure interference along the radial direction of the tank body. Through the cooperation of the protective sleeve 31 and the protective baffle 32, the dynamic pressure interference brought by the slurry to the measuring mechanism 1 during stirring can be greatly reduced, thereby ensuring the accuracy of the measurement data of the tank level gauge.

[0021] The cross-section of the protective sleeve 31 is arc-shaped, forming an arc opening 311 along the length of the protective sleeve 31. The arc opening 311 surrounds the end of the pressure-guiding tube 21 that extends into the interior of the tank. During stirring, the arc surface of the protective sleeve 31 blocks the dynamic pressure, which can reduce most of the dynamic pressure interference, making the data measured by the pressure-guiding tube on the liquid level gauge at the arc opening 311 more accurate. Preferably, the arc opening 311 is semicircular in shape, and the direction of the arc opening 311 is the same as the flow direction of the fluid flowing through the protective sleeve 31 during stirring. The use of this shape of the arc opening 311 reduces the resistance encountered by the slurry when flowing through the protective sleeve 31 during stirring.

[0022] The protective baffle 32 is circular and positioned on the side of the arc opening 311 facing away from the tank wall. Preferably, the top-view width of the protective sleeve 31 is less than half the diameter of the protective baffle 32, enhancing the protective baffle's ability to block radial dynamic pressure. Furthermore, the protective baffle 32 is preferably made of steel, which offers increased strength and resistance to damage, thereby extending the life of the protective mechanism 3.

[0023] The pressure-guiding mechanism 2 also includes a drain valve 22, which is connected to the pressure-guiding pipe 21 outside the tank body. The drain valve 22 can regularly drain the slurry in the pressure-guiding pipe 21 to avoid the deposition of solid slurry in the pressure-guiding pipe 21, thereby extending the service life of the pressure-guiding mechanism 2.

[0024] The measuring mechanism 1 includes a liquid level gauge 11 and a shut-off valve 12. The shut-off valve 12 is connected between the liquid level gauge 11 and the pressure pipe 21. At the same time, the liquid level gauge 11 is a static pressure level gauge. Through the shut-off valve 12, the connection or disconnection between the pressure pipe 21 and the liquid level gauge 11 can be flexibly adjusted so that the measurement of the liquid level gauge 11 has the function of being turned on or off, thereby extending the service life of the measuring mechanism 1.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
