[0002] The pressure level gauge is a common device used to measure the height of the liquid in a container. It has the advantages of high accuracy and not easy to damage. Figure 1 As shown, the installation of the existing pressure level gauge 10 is to connect a connecting pipe 21 (also called a pressure pipe) to the side of the container 20, and then insert one end of the pressure sensor 11 of the pressure level gauge 10 into the connecting pipe 21, and the pressure sensor 11 is fixed to the end of the connecting pipe 21 away from the container 20 through a flange. The pressure sensor 11 can sense the pressure signal of the material in the container 20 through the connecting pipe 21, and then measure the liquid level of the material in the container 20. However, for some materials with special properties (such as high-concentration amino acid slurry), the installation structure of the existing pressure level gauge often leads to the problem of being unable to accurately measure the liquid level of the material in the container. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that the installation structure of the existing pressure type liquid level gauge makes it impossible to accurately measure the liquid level of materials with special properties in a container, and to provide an installation structure of a pressure type liquid level gauge and a container having the same, wherein the installation structure can ensure that the pressure type liquid level gauge can accurately measure the liquid level of materials with special properties.

[0004] In order to achieve the above-mentioned purpose, the utility model provides, on the one hand, a mounting structure of a pressure liquid level gauge, which is used to install the pressure liquid level gauge on a container. The mounting structure includes a mounting plate fixed on the surface of the container, and a through hole is provided on the mounting plate.

[0008] Preferably, the plurality of bolts are evenly spaced around the through hole.

[0009] Preferably, the mounting plate is provided with a plurality of reserved holes for the plurality of bolts to pass through one by one and be fixed by welding.

[0010] Preferably, a groove extending along the circumference of the through hole is provided on the hole wall of the through hole, and a sealing member is provided in the groove to form a sealing fit with the outer surface of the pressure sensor.

DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0025] The inventors of the present application have found in practice that in a container 20 storing materials with special properties such as high-concentration amino acid crystal slurry, the high-concentration amino acid crystal slurry with poor fluidity will hang on the wall in the connecting tube 21, which will cause the connecting tube 21 to be blocked over time, so that the pressure sensor 11 inserted in the connecting tube 21 cannot effectively contact the material in the container 20, and thus the pressure level gauge 10 cannot accurately measure the material level in the container 20. The inventors also found that for some materials that are easy to crystallize or deposit, the pressure level gauge 10 using the traditional installation structure will have the problem of inaccurate measurement.

[0026] To this end, the utility model provides an installation structure of a pressure level gauge 10, which is used to install the pressure level gauge 10 on the container 20, and use the pressure level gauge 10 to monitor the material level in the container 20 in real time. Figure 2 As shown, in one embodiment of the utility model, the mounting structure includes a mounting plate 30 fixed on the surface of the container 20, and a through hole 31 is provided on the mounting plate 30. The pressure sensor 11 of the pressure level gauge 10 passes through the through hole 31 and extends into the container 20, and the outer surface of the pressure sensor 11 is sealed with the hole wall of the through hole 31.

[0027] In the technical solution provided by the utility model, a mounting plate 30 having a through hole 31 is fixed on the surface of the container 20, so that the pressure sensor 11 of the pressure level gauge 10 passes through the through hole 31 and extends to the inside of the container 20, thereby being able to fully contact the material in the container 20, thereby avoiding the problem in the prior art that the connecting pipe 21 is blocked by the material, resulting in the pressure sensor 11 being unable to effectively contact the material, thereby causing the pressure level gauge 10 to be unable to accurately measure the material level in the container 20.

[0028] In some embodiments, the mounting structure further includes a connecting component, and the connecting component is used to connect and fix the pressure sensor 11 and the mounting plate 30 .

[0029] In the present invention, the connection assembly can be any appropriate structural form, as long as the pressure sensor 11 of the pressure level gauge 10 can be fixed to the mounting plate 30. In some embodiments, the connection assembly includes a flange 40 and a plurality of bolts 50, wherein the flange 40 is coaxially sleeved on the outside of the pressure sensor 11, and the plurality of bolts 50 are vertically connected to the mounting plate 30 and extend in a direction away from the container 20, and the plurality of bolts 50 are inserted into the plurality of fixing holes 41 on the flange 40 one by one and are locked and fixed by nuts 42.

[0030] In the utility model, the flange 40 can be directly fixed on the outside of the pressure sensor 11. When the pressure sensor 11 passes through the through hole 31 on the mounting plate 30 and is inserted into the container 20, the bolt 50 just passes through the fixing hole 41 on the flange 40. After being inserted into place, the flange 40 is locked and fixed with the nut 42 to fix the relative position of the pressure sensor 11 and the mounting plate 30.

[0031] It is understandable that the method of directly fixing the flange 40 to the outside of the pressure sensor 11 can ensure that the pressure sensor 11 is inserted into the container 20 at a preset depth after the flange 40 is connected and fixed to the mounting plate 30. However, the method of directly fixing the flange 40 to the outside of the pressure sensor 11 has higher installation requirements. In the process of inserting the pressure sensor 11 into the container 20 through the through hole 31, the bolts 50 on the mounting plate 30 must be aligned with the fixing holes 41 on the flange 40. Therefore, in some embodiments, the flange 40 is movably coaxially sleeved on the pressure sensor 11. During the installation process of this solution, the pressure sensor 11 can be first inserted into the container 20 through the through hole 31, and then the flange 40 sleeved on the pressure sensor 11 can be moved in a direction close to the container 20, so that the bolts 50 on the mounting plate 30 pass through the fixing holes 41 on the flange 40, and then it can be tightened and fixed by the nuts 42. It should be noted that if Figure 2As shown, in this solution, a corresponding stopper 111 needs to be provided on the pressure sensor 11 to form a stopper match with the flange 40 , so as to fix the pressure sensor 11 to the mounting plate 30 .

[0032] It should be noted that, in the present invention, the purpose of providing multiple bolts 50 is to ensure the connection effect between the flange 40 and the mounting plate 30. In some embodiments, in order to ensure uniform connection force, the multiple bolts 50 are evenly spaced around the through hole 31. The above solution can ensure that the flange 40 is reliably fixed to the mounting plate 30.

[0033] The utility model does not specifically limit the specific number of the bolts 50 , for example, there can be four bolts 50 , which are evenly spaced around the through hole 31 of the mounting plate 30 , and the four bolts 50 can be inserted into the four fixing holes 41 on the flange 40 one by one and locked and fixed by nuts 42 .

[0034] In the present invention, the bolts 50 can be arranged on the mounting plate 30 in any appropriate form, as long as they can be conveniently connected to the flange 40 sleeved on the pressure sensor 11, thereby fixing the pressure sensor 11 to the mounting plate 30. Figure 3 and Figure 4 As shown, the mounting plate 30 is provided with a plurality of reserved holes 32 for the plurality of bolts 50 to pass through one by one and be fixed by welding.

[0035] It should be noted that when the bolts 50 pass through the reserved holes 32 on the mounting plate 30 and are fixed by welding, it should be ensured that the welding is reliable to prevent the material in the container 20 from leaking through the reserved holes 32 .

[0036] In some embodiments, in combination Figure 6 As shown, a bolt placement hole 33 is provided on one side of the mounting plate 30 facing the outside of the container 20, and the bolt placement hole 33 has a bolt body accommodating portion 331 and a bolt head accommodating portion 332 arranged in sequence from the outside to the inside along the thickness direction of the mounting plate 30, and the bolt placement hole 33 extends to the side of the mounting plate 30 so that the bolt 50 can be placed therein from the side of the mounting plate 30. It can be understood that, through the above-mentioned structural arrangement, there is no need to set a reserved hole 32 penetrating the plate body of the mounting plate 30, thereby eliminating the risk of the material in the container 20 leaking out through the reserved hole 32.

[0037] Combination Figure 7As shown, during the specific installation, the mounting plate 30 is first fixed to the surface of the container 20. When the pressure sensor 11 of the pressure level gauge 10 passes through the through hole 31 and extends into the interior of the container 20, the bolt 50 is placed into the bolt placement hole 33 from the side of the mounting plate 30, and the flange 40 mounted on the pressure sensor 11 is moved toward the direction close to the container 20, so that the bolt 50 passes through the fixing hole 41 on the flange 40, and then is tightened and fixed by the nut 42.

[0038] In the present invention, the pressure sensor 11 extends into the container 20 through the through hole 31 provided on the mounting plate 30, and contacts the material in the container 20, so as to realize real-time monitoring of the material level. The outer surface of the pressure sensor 11 and the hole wall of the through hole 31 can be sealed in any appropriate form to prevent the material in the container 20 from leaking to the outside of the container 20 through the gap between the pressure sensor 11 and the through hole 31. In some embodiments, the hole wall of the through hole 31 is provided with a groove 311 extending along the circumference thereof, and a sealing member 60 is provided in the groove 311 to form a sealing match with the outer surface of the pressure sensor 11.

[0039] In the present invention, the sealing member 60 may be made of any appropriate material type, for example, a rubber sealing ring.

[0040] In some embodiments, a plurality of the grooves 311 are provided, and the plurality of the grooves 311 are spaced apart along the length direction of the through hole 31 . The seal 60 is provided in each of the grooves 311 to form a sealing fit with the outer surface of the pressure sensor 11 .

[0041] It can be understood that by providing a plurality of grooves 311 and providing a seal 60 in each groove 311 , the sealing effect between the outer surface of the pressure sensor 11 and the hole wall of the through hole 31 is effectively ensured.

[0042] Combination Figure 5 As shown, in some embodiments, considering the thickness of the mounting plate 30 and the width of a single groove 311, a mounting tube 34 extending outward and concentric with the through hole 31 is provided at the hole edge of the through hole 31, and a plurality of grooves 311 are arranged on the inner wall of the mounting tube 34 to solve the problem that the thickness of the mounting plate 30 is not enough to arrange a plurality of grooves 311.

[0043] In the present invention, the mounting plate 30 can be fixed to the surface of the container 20 in any appropriate form. In some embodiments, a mounting hole 22 is opened on the wall of the container 20, and the outer edge of the mounting plate 30 is welded and fixed to the hole edge of the mounting hole 22.

[0044] The present invention does not impose any special limitation on the specific shape of the mounting plate 30 , and it may be, for example, circular, square, or any other suitable shape.

[0045] For example, in a specific embodiment of the present invention, the mounting plate 30 is circular with a diameter of 200 mm, a through hole 31 with a diameter of 120 mm is provided at the center of the mounting plate 30, a groove 311 extending along the circumference of the through hole 31 is provided on the hole wall of the through hole 31, and the width of the groove 311 is 5 mm and the depth is 5 mm. The sealing member 60 is a rubber sealing ring with a thickness of 5 mm and a width of 8 mm. When the rubber sealing ring is placed in the groove 311, it can protrude from the groove 311, thereby forming a sealing fit with the outside of the pressure sensor 11.

[0046] The second aspect of the utility model provides a container 20 , on which a pressure type liquid level gauge 10 is installed. The pressure type liquid level gauge 10 is installed on the container 20 through the above-mentioned installation structure.

[0047] By adopting the above-mentioned installation structure, the pressure sensor 11 of the pressure level gauge 10 can effectively contact the material in the container 20, ensuring that the pressure level gauge 10 can accurately monitor the liquid level of the material in the container 20. The container 20 provided by the utility model can be suitable for the storage of materials with various special properties, such as high-concentration amino acid slurry, or other materials that are easy to crystallize, or other materials that are easy to deposit, and can accurately monitor the liquid level of the material in the container 20 in real time.

[0048] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
