DETAILED DESCRIPTION
[0033] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.
[0034] Because the liquid level meter in the limestone slurry tank in the prior art is easy to be blocked, the actual liquid level height in the limestone slurry tank cannot be accurately measured by the liquid level meter, and the staff cannot know the liquid level height in the limestone slurry tank in real time, so that the limestone slurry may overflow from the top of the limestone slurry tank.
[0035] To solve the above technical problems, the application provides a liquid level overrun automatic alarm applied to the slurry tank 4, which comprises a mounting bracket 1, a liquid level detection assembly 2 and an alarm assembly 3.
[0036] The mounting bracket 1 is fixed to the inside of the slurry tank 4.
[0037] The liquid level detection assembly 2 is fixed to the mounting bracket 1, and the height of the liquid level detection assembly 2 from the bottom of the slurry tank 4 is a calibration height.
[0038] The alarm assembly 3 is electrically connected with the liquid level detection assembly 2, and the alarm assembly 3 sends a warning when the liquid level height in the slurry tank 4 reaches the calibration height.
[0039] As shown in Figure 1 and Figure 3 , specifically, the mounting bracket 1 is arranged in the inside of the slurry tank 4. In this embodiment, the slurry tank 4 is a limestone slurry tank, the mounting bracket 1 can be fixed to the inner side wall of the slurry tank 4, and the mounting bracket 1 is located in the upper region of the slurry tank 4.
[0040] The liquid level detection assembly 2 can be fixed to the mounting bracket 1, so that the height of the liquid level detection assembly 2 from the bottom of the slurry tank 4 is a calibration height. The calibration height represents that the height of the liquid level detection assembly 2 from the bottom of the slurry tank 4 is a fixed height, which can be set according to actual conditions.
[0041] The alarm assembly 3 is arranged outside the slurry tank 4, and the alarm assembly 3 can be electrically connected with the liquid level detection assembly 2. When the liquid level height in the slurry tank 4 reaches the calibration height, the liquid in the slurry tank 4 can immerse the liquid level detection assembly 2, and the liquid level detection assembly 2 can control the alarm assembly 3 to send a warning, so as to remind the staff that the liquid level in the slurry tank 4 is too high, and the staff needs to lower the liquid level height in the slurry tank 4 in time, thereby preventing the limestone slurry from overflowing from the top of the slurry tank 4.
[0042] As shown in Figure 1 and Figure 2As shown, in some embodiments, the liquid level detection component 2 includes a first detection unit 21 and a second detection unit 22. The height of the first detection unit 21 relative to the bottom of the slurry tank 4 is a first preset height, and the height of the second detection unit 22 relative to the bottom of the slurry tank 4 is a second preset height. The second preset height is greater than the first preset height. When the liquid level in the slurry tank 4 reaches the first preset height, the alarm component 3 issues a first-level warning. When the liquid level in the slurry tank 4 reaches the second preset height, the alarm component 3 issues both a first-level warning and a second-level warning.
[0043] Specifically, the liquid level detection component 2 may include a first detection unit 21 and a second detection unit 22. In this embodiment, both the first detection unit 21 and the second detection unit 22 can be used to detect the liquid level. The first detection unit 21 and the second detection unit 22 are set at different heights. The height of the first detection unit relative to the bottom of the slurry tank 4 is a first preset height. The first preset height is a distance away from the top of the slurry tank 4. The height of the second detection unit 22 relative to the bottom of the slurry tank 4 is a second preset height. The second preset height is greater than the first preset height, that is, the second detection unit 22 is closer to the top of the slurry tank 4 than the first detection unit 21.
[0044] When the liquid level in the slurry tank 4 reaches the first preset height, the liquid in the slurry tank 4 first comes into contact with the first detection unit 21, that is, the first detection unit 21 comes into contact with the liquid. The first detection unit 21 can control the alarm component 3 to issue a first-level warning. The first-level warning indicates that the liquid level in the slurry tank 4 is already relatively high, and the staff needs to pay attention to whether the liquid in the slurry tank 4 is leaking out, but it is not necessary to lower the liquid level inside the slurry tank 4.
[0045] When the liquid level in the slurry tank 4 reaches the second preset height, the liquid in the slurry tank 4 has completely submerged the first detection unit 21, and the second detection unit 22 is also in contact with the liquid in the slurry tank 4. At this time, the second detection unit 22 can control the alarm component 3 to issue a level two warning, and the alarm component 3 also issues a level one warning at the same time. The level two warning indicates that the liquid level in the slurry tank 4 is about to overflow, and the staff needs to reduce the liquid level inside the slurry tank 4 in time to further prevent the limestone slurry from overflowing from the top of the slurry tank 4.
[0046] like Figure 2 As shown, in some embodiments, the first detection unit 21 includes two probes 211. The two probes 211 are on the same horizontal plane, and the height of the two probes 211 relative to the bottom of the slurry tank 4 is a first preset height. When the liquid level in the slurry tank 4 reaches the first preset height, the two probes 211 are simultaneously immersed in the slurry. The two probes 211 are electrically connected so that the alarm component 3 issues a first-level warning.
[0047] Specifically, the first detection unit 21 may include two probes 211, which are located on the same horizontal plane, that is, the two probes 211 are at the same height from the bottom of the slurry tank 4, and the height of the two probes 211 relative to the bottom of the slurry tank 4 is a first preset height.
[0048] When the liquid level in the slurry tank 4 reaches the first preset height, the two probes 211 simultaneously come into contact with the limestone slurry. When the two probes 211 are simultaneously immersed in water, the circuit between them will be connected. This connection will generate an electrical signal, which can trigger the alarm component 3 to issue a first-level warning. The alarm component 3 can reliably issue warnings.
[0049] Similarly, the second detection unit 22 may also include two probes 211. When the liquid level in the slurry tank 4 reaches the second preset height, the two probes 211 on the second detection unit 22 simultaneously come into contact with the limestone slurry, causing the alarm component 3 to issue a level two warning.
[0050] like Figure 1 As shown, in some embodiments, the alarm component 3 includes a signal light, which is electrically connected to the first detection unit 21. When the liquid level in the slurry tank 4 reaches a first preset height and submerges the first detection unit 21, the signal light flashes to issue a first-level warning.
[0051] Specifically, the alarm component 3 may include a signal light, preferably a red signal light. The signal light is located outside the slurry tank 4 and can be electrically connected to the first detection unit 21. When the liquid level inside the slurry tank 4 reaches a first preset height, the first detection unit 21 can control the signal light to flash, thereby issuing a first-level warning. After seeing the signal light flash, the staff will know that the liquid level inside the slurry tank 4 is already relatively high, and at this time the staff will pay more attention to the liquid level in the slurry tank 4.
[0052] like Figure 1 As shown, in some embodiments, the alarm component 3 includes a cell detector, which is electrically connected to the second detection unit 22. When the liquid level in the slurry tank 4 reaches a second preset height and submerges the second detection unit 22, the cell detector sounds a level two warning.
[0053] Specifically, the alarm component 3 can further include a buzzer, the buzzer is arranged outside the slurry tank 4, and the buzzer can be electrically connected with the second detection unit 22; when the liquid level in the slurry tank 4 reaches the first preset height, the second detection unit 22 is in contact with the liquid, and the buzzer can be controlled by the second detection unit 22 to ring, so as to issue a second warning; after the staff hears the sound, it is known that the liquid level in the slurry tank 4 has almost overflowed, and the staff can timely reduce the liquid level in the slurry tank 4 to avoid the slurry from leaking out of the top of the slurry tank 4.
[0054] As shown in Figure 2 , in some embodiments, the liquid level detection assembly 2 further includes two protective nets 7, and the two protective nets 7 can be respectively arranged on the first detection unit 21 and the second detection unit 22.

[0056] As shown in Figure 2 and Figure 4 , in some embodiments, the liquid level detection assembly 2 further includes two protective nets 7, and the two protective nets 7 can be respectively arranged on the first detection unit 21 and the second detection unit 22.

[0058] As shown in Figure 2 and Figure 4 , in some embodiments, the mounting bracket 1 includes a first mounting plate 11, the first mounting plate 11 is connected with the connecting plate 5, and a plurality of mounting holes 111 are arranged at intervals on the first mounting plate 11; the liquid level detection assembly 2 and the alarm component 3 are electrically connected through a line, and the line is arranged in the mounting hole 111.
