[0033] The following will be combined with the specific implementation of the present invention to clearly and completely describe the technical solution in the present invention. Obviously, the described implementation is only a part of the implementation of the present invention, not all of the implementation. Based on the implementation of the present invention, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-14 As shown, a magnetic flap level gauge for chemical industry of the present invention comprises a connecting pipe 1, a magnetic float 2, two support frames 3, thermal insulation cotton 4, a flap box 5 and a reinforcement strip 6.

[0035] The connecting pipe 1 is arranged in the vertical direction, and its two ends are connected with the tank body to be tested. The flap box 5 is arranged on one side of the connecting pipe 1. A flap column is arranged inside the flap box 5. The flap column is painted with two colors. The magnetic float 2 is slidably arranged in the connecting pipe 1. A magnetic suction component is arranged inside the magnetic float 2, and the magnetic float 2 can float on the liquid surface. When the magnetic float 2 rises to a certain height with the liquid level, it can drive the flap column below the corresponding height in the flap box 5 to rotate, so as to display the liquid level of the medium in the container to be tested by using the difference in color.

[0036] In winter, in order to prevent the medium in the connecting pipe 1 from freezing or other solidification phenomena, it is necessary to wrap a layer of thermal insulation cotton 4 on the outside of the connecting pipe 1. For this purpose, a support frame 3 is provided. The two ends of the support frame 3 are rotatably arranged on the connecting pipe 1. The middle position of the support frame 3 is spaced apart from the connecting pipe 1, and the two support frames 3 are detachably fixedly connected. When wrapping the thermal insulation cotton 4, first disassemble the connection between the two support frames 3, and then insert the thermal insulation cotton 4 between the two support frames 3 and the connecting pipe 1. Then, rotate the support frame 3 to put the thermal insulation cotton 4 on the outside of the connecting pipe 1. Finally, use the fixed connection of the two support frames 3 to fix the two ends of the thermal insulation cotton 4 between the two support frames 3, so as to realize the installation and fixation of the thermal insulation cotton 4. In order to prevent the thermal insulation cotton 4 from covering the flip box 5, the flip box 5 is fixedly arranged on the side of the support frame 3 away from the connecting pipe 1.

[0037] Since the support frame 3 is rotatably connected to the connecting pipe 1, the support frame 3 can also be rotated according to actual needs, such as Figure 1-Figure 3 As shown, the flip box 5 can be rotated to the first position, the second position and the third position respectively, so that the flip box 5 faces the direction that is convenient for the operator to observe.

[0038] In summer, in order to prevent the medium inside the connecting pipe 1 from overheating and affecting the normal operation of the magnetic float 2, the thermal insulation cotton 4 needs to be disassembled. At this time, the connection between the two support frames 3 is disassembled, and the support frames 3 are rotated to easily remove the thermal insulation cotton 4 from the connecting pipe 1. Compared with the method of internally installing the thermal insulation cotton 4 in the prior art, the convenience of disassembling the thermal insulation cotton 4 can be improved.

[0039] When the support frame 3 is rotated or the thermal insulation cotton 4 is disassembled and assembled, the distance between the flap box 5 and the magnetic float 2 will be affected, resulting in a change in the intensity of the magnetic signal received by the flap box 5, thereby interfering with the consistency of the detection result of the magnetic flap level gauge. In order to avoid this problem, the rotation axis of the support frame 3 is made to coincide with the axis of the magnetic float 2, that is, the support frame 3 is rotated around the axis of the magnetic float 2. When the support frame 3 is rotated or the thermal insulation cotton 4 is disassembled and assembled, the distance between the support frame 3 and the magnetic float 2 can be ensured to remain unchanged, that is, the distance between the flap box 5 and the magnetic float 2 remains unchanged.

[0040] like Figure 4 and Figure 5 As shown, the connecting pipe 1 includes a vertical pipe 11, two rotating seats 12, two horizontal pipes 13 and two end pipes 14. The vertical pipe 11 is provided with an inner cavity 101, and the magnetic float 2 is slidably arranged in the inner cavity 101. The axis of the inner cavity 101 is parallel to the axis of the vertical pipe 11 and is arranged at intervals, that is, the inner cavity 101 is eccentrically arranged with the vertical pipe 11, and the axis of the magnetic float 2 is eccentrically arranged with the axis of the vertical pipe 11. When the support frame 3 rotates around the axis of the magnetic float 2, the distance between the middle position of the support frame 3 and the vertical pipe 11 will change. Figure 7 As shown, at this time, the two support frames 3 rotate to the side where the axis of the magnetic float 2 is away from the axis of the vertical tube 11, and the distance between the middle position of the two support frames 3 and the vertical tube 11 is relatively large, and the thermal insulation cotton 4 of smaller thickness can be easily inserted between the support frames 3 and the vertical tube 11. After the length of the thermal insulation cotton 4 inserted between the support frames 3 and the vertical tube 11 meets the requirements, the two support frames 3 are rotated to the side where the axis of the vertical tube 11 is away from the axis of the magnetic float 2. During this process, the distance between the middle position of the support frames 3 and the vertical tube 11 gradually decreases, which will support the surrounding side of the thermal insulation cotton 4, thereby improving the close contact between the thermal insulation cotton 4 and the vertical tube 11, and facilitating the installation of the thermal insulation cotton 4. By reversing the above steps, the thermal insulation cotton 4 can also be easily disassembled. At the same time, the thermal insulation cotton 4 will not always be against the support frames 3 during the disassembly and assembly process, which is also beneficial to protecting the thermal insulation cotton 4 and extending its service life.

[0041] The swivel seat 12 is fixedly arranged on the outside of the vertical tube 11, and its axis coincides with the axis of the inner cavity 101, that is, the swivel seat 12 is coaxially arranged with the magnetic float 2, but not coaxially arranged with the vertical tube 11. The two swivel seats 12 are parallel and spaced apart, and the two ends of the support frame 3 are rotatably arranged on the two swivel seats 12 respectively, so as to achieve the effect that the support frame 3 rotates around the axis of the inner cavity 101, but not around the axis of the vertical tube 11.

[0042] The transverse tube 13 is used to connect the vertical tube 11 and the tank to be tested. One end of the transverse tube 13 is fixedly set on the vertical tube 11 and is connected to the inside thereof. The two transverse tubes 13 are parallel and spaced apart. One transverse tube 13 is the inlet of the medium, and the other transverse tube 13 is the outlet of the medium. The magnetic float 2, the support frame 3, the thermal insulation cotton 4 and the flip box 5 are all located between the two transverse tubes 13. No corresponding detection mechanism is installed at other positions on the level gauge other than between the two transverse tubes 13. Therefore, its thermal insulation can be achieved by directly covering the thermal insulation cotton 4 without the need for other components for support.

[0043] The ends of the horizontal tube 13 are preferably not connected to the ends of the vertical tube 11, but the two end tubes 14 are fixedly arranged on the two ends of the vertical tube 11 and connected to the interior thereof. At this time, the vertical tube 11 has four interfaces, which are connected to the tank body to be tested via the interfaces of the two horizontal tubes 13, and the inner wall of the vertical tube 11 and the magnetic float 2 can be flushed and cleaned via the two interfaces of the end tubes 14. In order to improve the flushing effect, it is preferred that the axis of the end tube 14 close to one end of the vertical tube 11 coincide with the axis of the magnetic float 2. During the detection process of the magnetic flap level gauge, the two end tubes 14 need to be blocked.

[0044] The transverse tube 13 is arranged on the side of the vertical tube 11 close to the tank body to be tested. During the use of the liquid level meter, in order to facilitate the observation of the detection result of the flap box 5, the flap box 5 will not be rotated to the position on the vertical tube 11 close to the side of the transverse tube 13. Therefore, the axis of the vertical tube 11 is located on the side where the axis of the inner cavity 101 is away from the transverse tube 13. When the support frame 3 is rotated to the side of the vertical tube 11 close to the transverse tube 13, the interval between the middle position of the support frame 3 and the vertical tube 11 is larger than the interval between the middle position of the support frame 3 and the vertical tube 11 when the support frame 3 is rotated to other positions, so that when the support frame 3 is rotated to the side of the vertical tube 11 close to the tank body to be tested, it is convenient to insert the thermal insulation cotton 4, and when the support frame 3 is rotated to other positions, the surrounding side of the thermal insulation cotton 4 can be supported to ensure the fixing effect of the thermal insulation cotton 4.

[0045] In order to allow the flip column in the flip box 5 to receive a uniform magnetic signal, it is preferred to make the distances between the two ends of the flip box 5 along its width direction and the axis of the inner cavity 101 equal, that is, the flip column in the flip box 5 is symmetrically arranged about the axis of the magnetic float 2 to avoid the problem of lateral deviation of the flip column.

[0046] The support frame 3 includes a fixing rod 31, a rotating ring 32 and a protruding portion 33. Figure 8 As shown, the fixed rod 31 is parallel to the connecting pipe 1 and is arranged at intervals, the swivel 32 is fixedly arranged at both ends of the fixed rod 31, and is rotatably connected to the swivel seat 12 in the connecting pipe 1, and the rotation axis of the swivel 32 coincides with the axis of the magnetic float 2, and the flap box 5 is fixedly arranged on the side of the fixed rod 31 away from the connecting pipe 1, and the rotation of the swivel 32 will not affect the distance between the flap box 5 and the magnetic float 2.

[0047] like Fig. 9 As shown, the side of the fixing rod 31 close to the connecting pipe 1 is in an arc shape to adapt to the arc-shaped side wall of the thermal insulation cotton 4, and the side of the fixing rod 31 away from the connecting pipe 1 is in a flat shape. When the two support frames 3 are fixedly connected, the sides of the two fixing rods 31 away from the connecting pipe 1 are flush, so that the flip box 5 can be stably fixed on the two fixing rods 31.

[0048] like Fig.10 As shown, the two fixing rods 31 are preferably fixedly connected by bolts, the two fixing rods 31 are parallel and spaced apart, a side of the fixing rod 31 close to the other fixing rod 31 and a side of the fixing rod 31 away from the other fixing rod 31 are parallel to each other, and are perpendicular to a side of the fixing rod 31 away from the connecting pipe 1. When the two fixing rods 31 are flush with the sides away from the connecting pipe 1, the bolts are inserted into the two fixing rods 31, which not only allows the screw heads and nuts of the bolts to abut against the two fixing rods 31, but also allows the two ends of the thermal insulation cotton 4 to be evenly held between the two fixing rods 31, so as to achieve a good positioning effect.

[0049] like Figure 8 and Fig. 9 As shown, the protrusion 33 is fixedly arranged on the fixing rod 31, and the protrusion 33 extends out of the side of the fixing rod 31 close to the connecting pipe 1. The side of the fixing rod 31 close to the connecting pipe 1 abuts against the outer side of the thermal insulation cotton 4. After the protrusion 33 extends out of the side of the fixing rod 31 close to the connecting pipe 1, the distance between the protrusion 33 and the connecting pipe 1 is smaller than the distance between the side of the fixing rod 31 close to the connecting pipe 1 and the connecting pipe 1. Figure 7 As shown, at this time, the protrusions 33 are respectively located at a position where one fixing rod 31 is away from the other fixing rod 31. When the two support frames 3 are rotated to the left, the protrusions 33 can first contact the peripheral side of the thermal insulation cotton 4, and then the side of the entire fixing rod 31 close to the connecting pipe 1 is pressed against the outer side of the thermal insulation cotton 4, so that the thermal insulation cotton 4 is tightened step by step, and the thermal insulation cotton 4 is tightly pressed against the peripheral side of the connecting pipe 1, thereby improving the installation firmness of the thermal insulation cotton 4; conversely, when removing the thermal insulation cotton 4, the side of the fixing rod 31 close to the connecting pipe 1 can be separated from the peripheral side of the thermal insulation cotton 4 as soon as possible, so that the protrusions 33 can gradually separate from the peripheral side of the thermal insulation cotton 4, thereby reducing the friction between the thermal insulation cotton 4 and the outer wall of the connecting pipe 1 during the removal process. Similarly, if Figure 1 As shown, the center point of the arc surface of the fixing rod 31 close to the connecting pipe 1 should be located on the left side of the axis of the connecting pipe 1. When performing the above operation, the arc surface of the fixing rod 31 close to the connecting pipe 1 can gradually contact or disengage with the thermal insulation cotton 4 instead of contacting or disengaging with it all at once.

[0050] like Fig. 9 As shown, the protrusion 33 also extends out of the fixing rod 31 near the side of the other fixing rod 31, as shown in FIG. Figure 1-Figure 3 As shown, when the two ends of the thermal insulation cotton 4 are fixedly arranged between the two support frames 3, the protrusion 33 can support the thermal insulation cotton 4 between the two support frames 3 to form a T shape, thereby preventing the ends of the thermal insulation cotton 4 from detaching from the two support frames 3, thereby improving the fixing firmness and anti-detachment effect of the thermal insulation cotton 4.

[0051] The reinforcement strip 6 is also used to reinforce the thermal insulation cotton 4 between the two support frames 3. Fig.11 As shown, the reinforcement strip 6 includes a mounting plate 61 and a supporting rod 62. The mounting plate 61 is fixedly arranged on the flip box 5, and the supporting rod 62 is fixedly arranged on a side of the mounting plate 61 away from the flip box 5. Figure 1 As shown, the mounting plate 61 and the abutting rod 62 both abut the end of the thermal insulation cotton 4, so that the end of the thermal insulation cotton 4 abuts the support frame 3, thereby improving the fixing firmness of the thermal insulation cotton 4. At the same time, the mounting plate 61 abuts against the two fixing rods 31, as shown in FIG. Figure 1 As shown, when the bolts between the two support frames 3 are tightened, the two fixing rods 31 abut against the two ends of the mounting plate 61, and the two support frames 3 will not be allowed to move further closer. This not only allows the planes on the two support frames 3 that are connected to the flip box 5 to be flush, but also prevents the two fixing rods 31 from approaching too close and squeezing and damaging the thermal insulation cotton 4, so that the reinforcement strip 6 also has a certain positioning effect.

[0052] The length of the supporting rod 62 is smaller than the axial length of the heat-insulating cotton 4 along the connecting pipe 1. Fig.12 As shown, the reinforcement strip 6 will only support the middle position of the end of the thermal insulation cotton 4, so it can also prevent the thermal insulation cotton 4 from moving along the axial direction of the connecting pipe 1, and enhance the fixing firmness of the thermal insulation cotton 4.

[0053] The reinforcement strip 6 is arranged at the middle position of the flap box 5. When the flap box 5 is fixed on the two support frames 3, the flap box 5 is located at the middle position of the two support frames 3, thereby ensuring the accuracy of the installation position of the flap box 5.

[0054] In some embodiments, a rotating groove 102 is provided on the rotating seat 12 in the connecting pipe 1, and the rotating ring 32 is configured to include a C-shaped rod 321 and a top screw 322, such as Fig.13 and Fig.14As shown, both ends of the C-shaped rod 321 are rotatably arranged in the rotating groove 102, and the fixing rod 31 is fixedly connected to the C-shaped rod 321, the top screw 322 passes through the C-shaped rod 321 and is connected to it by threaded matching, and the end of the top screw 322 close to the connecting pipe 1 is rotatably arranged in the rotating groove 102, as shown in FIG. Fig.14 As shown, the two ends of the C-shaped rod 321 and the right end of the top screw 322 jointly support the swivel 32 to rotate in the rotating groove 102. When the top screw 322 is rotated to move it to the left, the two ends of the C-shaped rod 321 are supported by the inner wall of the rotating groove 102, so that the C-shaped rod 321 and the fixed rod 31 can be moved to the right, so that the flap box 5 is close to the magnetic float 2. On the contrary, the flap box 5 can be moved away from the magnetic float 2, thereby adjusting the strength of the magnetic signal received by the flip column in the flap box 5, so that the present magnetic flap level gauge is suitable for different operating conditions or effectively cope with the problem of performance attenuation of the magnetic float 2.

[0055] The method of using a magnetic flap level gauge for chemical industry of the present invention is as follows: when installing the thermal insulation cotton 4, first rotate the two support frames 3 to the position as shown in the figure. Figure 7 The two support frames 3 are then rotated so that the two support frames 3 are located at appropriate positions, and the two ends of the thermal insulation cotton 4 are supported between the two support frames 3. Finally, the two support frames 3 are fixed, the flip box 5 is fixed on the two support frames 3, and the reinforcement strip 6 is inserted between the two support frames 3. The thermal insulation cotton 4 can be removed by reversing the above steps. During the use of the liquid level meter, the position of the flip box 5 can be adjusted by rotating the support frame 3 to make it easier for the operator to observe.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
