Abstract
Description
Technical Field
[0001] The present application relates to the technical field of acid etching tank monitoring, and in particular to a float device for an acid etching tank. Background Art
[0002] During the use of the acid etching tank, it is very important to monitor the liquid conditions inside the tank, such as the liquid level. However, since the tank is made of stainless steel and is basically airtight, these indicators are often not directly observable, resulting in inconvenient operation and potential safety hazards. At present, conventional monitoring methods include setting sensors on the outside of the tank to infer the conditions of the internal liquid indirectly. However, these methods are interfered by the internal conditions of the tank (such as pressure, temperature, etc.), resulting in inaccurate monitoring results. There are problems such as low accuracy and large interference, which cannot meet the needs of accurate monitoring of the liquid level inside the acid etching tank. Utility Model Content
[0003] In order to improve the accuracy of liquid level monitoring, the present application provides a float device for an acid etching tank.

[0006] By adopting the above technical solution, a float is provided, and the float can move in the movable tube along with the liquid level in the tank body. After the float moves, it drives the benchmark to move, so that it is convenient for staff to observe the liquid level, thereby improving the accuracy of liquid level monitoring.
[0007] Optionally, a scale plate corresponding to the benchmark is provided on the upper surface of the tank body.

[0010] By adopting the above technical solution, when one of the float balls is stuck, the liquid level in the tank body can be observed from the other float ball.
[0011] Optionally, the float ball is a polytetrafluoroethylene ball.
[0012] By adopting the above technical solution, the liquid in the tank body is corrosive, the polytetrafluoroethylene is corrosion-resistant, and the float is made of polytetrafluoroethylene, which can improve the corrosion resistance and durability of the float.
[0013] Optionally, the movable tube is provided with a plurality of through holes.
[0014] By adopting the above technical solution, a plurality of through holes are opened on the movable tube, so that the liquid in the tank body can enter the movable tube easily, thereby driving the float to move.
[0015] Optionally, a limiting ring is provided above the scale plate for limiting the position of the benchmark.
[0016] By adopting the above technical solution, since the length of the benchmark is long and the upper end of the benchmark lacks constraint, the benchmark is prone to bending, which affects subsequent use. Therefore, a limiting ring is provided to limit the free end of the benchmark, thereby reducing the possibility of bending of the benchmark.
[0017] Optionally, the limit ring is slidably connected to the scale plate along the vertical direction, and the limit ring is provided with a limit member for limiting the sliding position of the limit ring.
[0018] By adopting the above technical solution, since the float moves up and down and the length of the benchmark is long, the limit ring is provided with a sliding shape to facilitate moving the height of the limit ring, thereby facilitating the limiting of the benchmark in different states.
[0019] Optionally, connecting plates are provided on both sides of the limiting ring, the connecting plates are threadedly connected with limiting bolts, and the end faces of the limiting bolts abut against the scale plate.
[0020] By adopting the above technical solution, after the limit ring is adjusted to a suitable height, the limit bolt is rotated so that the limit bolt abuts against the scale plate, thereby limiting the height of the limit ring.
[0021] Optionally, the limiting ring is rotatably connected to a rotating wheel abutting against the benchmark, and a plurality of the rotating wheels are provided, and the plurality of the rotating wheels are arranged in a circular array around the axis of the limiting ring, and the benchmark is located in the middle of the plurality of rotating wheels.
[0022] In summary, the utility model has the following beneficial effects:
[0023] 1. A floating ball is provided, which can move in the movable tube along with the liquid level in the tank. When the floating ball moves, it drives the benchmark to move, so that the staff can observe the liquid level conveniently;
[0024] 2. Since the length of the benchmark is long and the upper end of the benchmark lacks constraints, the benchmark is prone to bending, which affects subsequent use. Therefore, a limit ring is set to limit the free end of the benchmark, thereby reducing the possibility of bending of the benchmark. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] Embodiment 1:
[0032] Example 1 of the present application discloses a float device for an acid etching tank, referring to Figure 1 and Figure 2 , including a tank body 1 and a movable tube 2, the tank body 1 has a cavity 12 inside, a cover plate 11 is provided on the upper part of the tank body 1, and a stirring assembly for stirring the liquid in the tank body 1 is fixedly connected to the cover plate 11. The movable tube 2 is located inside the tank body 1, and the upper end of the movable tube 2 is fixedly connected to the cover plate 11, and the movable tube 2 is connected to the outside of the tank body 1 through the cover plate 11. The axis direction of the movable tube 2 is vertically arranged, and a float 4 is arranged inside the movable tube 2, and a benchmark 41 is fixedly connected to the upper wall of the float 4, and the benchmark 41 is vertically arranged, and the upper end of the benchmark 41 extends to the outside of the tank body 1. A temperature sensor is arranged inside the float 4, which can monitor the temperature of the liquid in the tank body 1.
[0033] Reference Figure 1 and Figure 2 A scale plate 3 corresponding to the mark rod 41 is fixedly connected to the upper surface of the tank body 1. The scale plate 3 cooperates with the mark rod 41, so that the liquid level in the tank body 1 can be observed more intuitively.
[0034] Reference Figure 1 and Figure 2 There are two movable tubes 2, which are distributed along the width direction of the scale plate 3, and two benchmarks 41 are also correspondingly set. When one of the floats 4 is stuck, the liquid level in the tank body 1 can be observed from the other float 4.
[0035] Reference Figure 1 and Figure 2 The float 4 is a polytetrafluoroethylene ball. The liquid in the tank body 1 is corrosive, and polytetrafluoroethylene is corrosion-resistant. The float 4 is made of polytetrafluoroethylene to improve the corrosion resistance and durability of the float 4.
[0036] Reference Figure 1 and Figure 2 The movable tube 2 is penetrated by a plurality of through holes 21, so that the liquid in the tank body 1 can enter the movable tube 2, thereby driving the float 4 to move.
[0037] The implementation principle of Example 1 of the present application is as follows: a float 4 is provided, and the float 4 can move in the movable tube 2 along with the liquid level in the tank body 1. After the float 4 moves, it drives the marker 41 to move, thereby facilitating the staff to observe the liquid level.
[0038] Embodiment 2:
[0039] The difference between Example 2 and Example 1 is that, referring to Figure 3 and Figure 4 A limiting ring 5 for limiting the position of the benchmark 41 is provided above the scale plate 3. The limiting ring 5 is provided to limit the free end of the benchmark 41, thereby reducing the possibility of bending of the benchmark 41.
[0040] Reference Figure 3 and Figure 4 The outer peripheral wall of the limit ring 5 is fixedly connected with a sliding block 51, and the scale plate 3 is provided with a sliding groove 31, the length direction of the sliding groove 31 is vertically arranged, and the sliding block 51 is slidably connected to the sliding groove 31.

The limiting member is a limiting bolt 53, and the limiting bolt 53 is threadedly connected to the connecting plate 52, and the end face of the limiting bolt 53 abuts against the scale plate 3. Since the float 4 will move up and down, and the length of the benchmark 41 is relatively long, the limit ring 5 is provided with a sliding shape to facilitate the movement of the limit ring 5, so as to facilitate the limiting of the benchmark 41 in different states.
[0041] Reference Figure 3 and Figure 4The inner wall of the limiting ring 5 is provided with a plurality of rotating wheels 54, which are arranged in a circular array around the axial direction of the limiting ring 5, and the rotating wheels 54 are rotatably connected to the limiting ring 5. The rotating wheels 54 abut against the marker rod 41, and the marker rod 41 is located in the middle of the plurality of rotating wheels 54, thereby reducing the friction between the marker rod 41 and the limiting ring 5, thereby reducing the possibility of wear of the marker rod 41.
[0042] The implementation principle of Example 2 is as follows: since the length of the marker rod 41 is relatively long and the upper end of the marker rod 41 lacks constraint, the marker rod 41 is prone to bending, which affects subsequent use. Therefore, a limiting ring 5 is provided to limit the free end of the marker rod 41 through the limiting ring 5, thereby reducing the possibility of bending of the marker rod 41.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
