[0027] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0028] like Figures 1 to 2 As shown, this embodiment provides a liquid level measuring device for a flotation filter, which includes a support frame 1, a float assembly 2 and a measuring assembly 3. The measuring assembly 3 includes a measuring frame 31, a measuring instrument and a measuring piece 33. At least a portion of one end of the float assembly 2 is located in the flotation filter, and the other end of the float assembly 2 passes through the support frame 1 and slides with the support frame 1. The float assembly 2 can move with the liquid level of the flotation filter. The measuring frame 31 is arranged on the support frame 1, the measuring instrument is installed on the measuring frame 31, the measuring piece 33 is connected to the end face of the other end of the float assembly 2, the measuring piece 33 has a measuring plane, and the measuring instrument can measure the height of the measuring plane.

[0029] By using the liquid level measuring device for a flotation filter tank of the present invention, at least a portion of one end of the float assembly 2 is located in the flotation filter tank, so that the float assembly 2 can move with the liquid level of the flotation filter tank. At the same time, the other end of the float assembly 2 passes through the support frame 1 and slides with the support frame 1. The measuring piece 33 is connected to the end face of the other end of the float assembly 2. In this way, the measuring instrument can measure the liquid level of the flotation filter tank by measuring the height of the measuring plane, thereby achieving the purpose of accurately measuring the liquid level of the flotation filter tank. By using the liquid level measuring device for a flotation filter tank of this solution, the influence of unstable factors in the flotation filter tank on the measurement results is avoided, and the liquid level measurement can be made more accurate and reliable, effectively solving the problem that the liquid level measuring device in the prior art cannot accurately measure the liquid level of the flotation filter tank. Among them, the measuring instrument is an ultrasonic level meter.

[0030] In this embodiment, the float assembly 2 includes a float member 21 and a float column 22 that are interconnected. At least a portion of the float member 21 is located within the flotation filter tank, so that the float member 21 can move along with the liquid level within the flotation filter tank to display the liquid level within the flotation filter tank in real time. The float column 22 passes through the support frame 1 and slides with the support frame 1, and the measuring piece 33 is connected to the end face of the float column 22. With this arrangement, the liquid level within the flotation filter tank displayed by the float member 21 can be transmitted to the float column 22 and ultimately to the measuring piece 33, thereby achieving the purpose of measuring the liquid level within the flotation filter tank by measuring the height of the measuring plane using a measuring instrument.

[0031] In this embodiment, the shape of the buoyancy member 21 includes, but is not limited to, a conical or spherical shape. The buoyancy member 21 may also be a cylindrical or other shape. In this embodiment, the buoyancy member 21 is in the shape of an inverted cone, which allows the buoyancy member 21 to float stably on the liquid surface of the flotation filter.

[0032] Furthermore, the floating platform 21 has a receiving cavity and an injection hole 211. The injection hole 211 is connected to the receiving cavity. In this way, when the liquid in the flotation filter tank sloshes violently, mud and sand can be injected into the receiving cavity through the injection hole 211 to increase the weight of the floating platform 21 and prevent the floating platform 21 from tipping over.

[0033] Specifically, when the liquid level in the flotation filter is low, due to the limited length of the float column 22, the float member 21 of the float platform will be in a low position. In order to prevent the float column 22 from falling off the support frame 1, a limit buckle 4 is provided in the liquid level measurement device for the flotation filter. One end of the limit buckle 4 is connected to the measuring piece 33, and the other end of the limit buckle 4 extends in the radial direction of the float column 22 and extends out of the float column 22. In this arrangement, the limit buckle 4 can cooperate with the support frame 1 to stop the float column 22, thereby preventing the float column 22 from falling off.

[0034] In this embodiment, to facilitate installation of the measuring instrument, the measuring frame 31 includes a frame body 311 and a fixing frame 312. One end of the frame body 311 is connected to the support frame 1, and the fixing frame 312 is connected to the other end of the frame body 311. The measuring instrument is mounted on the fixing frame 312 to secure the measuring instrument.

[0035] Specifically, the support frame 1 includes a mounting frame 11 and a supporting frame 12. The mounting frame 11 can be connected to the wall of the flotation filter tank, and the supporting frame 12 is mounted on the mounting frame 11. The other end of the floating platform assembly 2 passes through the mounting frame 11 and the supporting frame 12 in sequence, slidingly engaging with the supporting frame 12. The measuring frame 31 is mounted on the supporting frame 12. This arrangement facilitates the installation of the floating platform assembly 2, the installation of the supporting frame 12, and the installation of the measuring frame 31.

[0036] Furthermore, the mounting frame 11 has an avoidance hole 111, and the supporting frame 12 has a mounting hole 121. With this arrangement, the other end of the floating platform assembly 2 is sequentially passed through the avoidance hole 111 and the mounting hole 121, and slides with the inner wall of the mounting hole 121, thereby guiding the movement of the floating platform assembly 2.

[0037] Specifically, the liquid level measuring device for the flotation filter tank further comprises a rain cover 5, which is mounted on the measuring frame 31. The rain cover 5 is provided to cover the floating platform assembly 2 and the measuring assembly 3 to prevent them from getting wet in the rain.

[0038] Specifically, the liquid level measuring device for the flotation filter further includes a reinforcing plate, one side of which is connected to the wall of the flotation filter, and the other side of which is connected to the support frame 1. This arrangement can enhance the connection strength between the support frame 1 and the wall of the flotation filter, thereby increasing the service life of the liquid level measuring device for the flotation filter.

[0039] Alternatively, the liquid level measuring device for the flotation filter can detect the liquid level of the flotation filter through a liquid level sensor and transmit a signal to the controller. The controller can control an electric regulating valve or other device to adjust the liquid level of the flotation filter.

[0040] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
