Description

Technical Field

[0001] This utility model relates to the field of conductive slurry storage technology, specifically to a float device for monitoring the liquid level of a conductive slurry storage tank. Background Technology

[0002] In the field of electronic materials production, conductive paste is a key raw material, and its storage status directly affects the stability of subsequent production and product quality. Due to the viscosity and precise composition of conductive paste, high requirements are placed on the monitoring of liquid level in the storage tank. Accurately controlling the liquid level can not only avoid production interruptions caused by insufficient raw materials, but also prevent overflow waste or safety risks caused by excessive storage.

[0003] Currently, most liquid level monitoring devices for conductive slurry storage tanks on the market use float-type devices. However, traditional float-type devices have many limitations in practical applications. On the one hand, the connection between the existing float and the liquid level transmission structure is mostly fixed welding or complex snap-fit ​​design. When the float needs to be repaired or replaced due to wear, corrosion or decreased sensitivity caused by long-term contact with slurry, it is often necessary to disassemble a large number of related components. The operation is cumbersome and time-consuming, which seriously affects production efficiency and increases labor costs.

[0004] On the other hand, traditional limiting structures lack stability, and the float is prone to shaking or shifting during the rise and fall of the liquid level, resulting in deviations in the liquid level monitoring data. The limiting components of some devices are difficult to adjust, making it difficult to adapt to the monitoring needs of different liquid level ranges. Moreover, they are prone to loosening after long-term use, further reducing the monitoring accuracy. In view of this, we propose a float device for liquid level monitoring of conductive slurry storage tanks. Utility Model Content

[0005] The purpose of this invention is to provide a float device for monitoring the liquid level of a conductive slurry storage tank. By setting two limiting components and cooperating with a cover that is hinged to the tank body, the problem of inconvenient, time-consuming and labor-intensive float disassembly and replacement is solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A float-type device for monitoring the liquid level of a conductive slurry storage tank includes a liquid level measuring mechanism, a tank body, a cover, and a base plate. The liquid level measuring mechanism is disposed inside the tank body, the tank body is mounted on the top surface of the base plate, and the cover is hinged to the top surface of the tank body. The liquid level measuring mechanism includes a float, a fixed cylinder located above the float, a telescopic rod fixed to the top surface of the float and slidably inserted into the fixed cylinder, and a liquid level rod fixed to the top surface of the fixed cylinder and slidably inserted into the cover. It also includes:

[0008] Two limiting components are symmetrically arranged on the outer wall of the fixed cylinder to limit the telescopic rod and the float. The limiting components include an L-shaped plate fixed on the outer wall of the fixed cylinder, a spring fixed at one end to the outer wall of the vertical end of the L-shaped plate, a movable plate fixed to the other end of the spring and slidably connected to the horizontal end of the L-shaped plate, and a limiting rod fixed on the outer wall of the movable plate and slidably inserted into the telescopic rod. A fixing rod is fixed on the front surface of the movable plate.

[0009] In a preferred embodiment, the limiting component further includes a pad fixed to the surface of the vertical end of the L-shaped plate near the fixed cylinder, and the spring is fixed between the pad on the same side and the movable plate on the same side and is arranged laterally.

[0010] In a preferred embodiment, the limiting rod is fixed on the side surface of the same-side movable plate near the fixed cylinder. The outer wall of the fixed cylinder is provided with two through holes that communicate with its inner cavity. The outer wall of the telescopic rod is provided with two limiting holes that correspond to the positions of the same-side through holes on the inner wall of the fixed cylinder and are adapted in size. The limiting rod passes through the same-side through holes on the outer wall of the fixed cylinder and is slidably inserted into the same-side limiting holes on the outer wall of the telescopic rod.

[0011] In a preferred embodiment, the bottom surface of the horizontal end of the L-shaped plate is provided with a limiting groove arranged horizontally, a moving block is fixed on the top surface of the movable plate, and a limiting block that is slidably connected to the limiting groove on the bottom surface of the horizontal end of the L-shaped plate on the same side is fixed on the top surface of the moving block.

[0012] In a preferred embodiment, the longitudinal cross-sectional shape of the guide groove on the bottom surface of the horizontal end of the L-shaped plate is I-shaped, and the shape of the limiting block is I-shaped to match the shape of the guide groove on the bottom surface of the horizontal end of the L-shaped plate.

[0013] In a preferred embodiment, the front surface of the horizontal end of the L-shaped plate is provided with two insertion holes arranged from left to right. The fixed rod is L-shaped. The limiting assembly also includes a screw threaded to the vertical end of the fixed rod, a rotating column coaxially fixed to the rear surface of the screw, a turntable coaxially fixed to the front surface of the screw, and a lever fixed to the front surface of the turntable near the edge. When the limiting rod and the limiting hole on the same side of the outer wall of the telescopic rod are slidably inserted together, the rotating column on the same side is slidably inserted together with the insertion hole on the front surface of the horizontal end of the L-shaped plate near the fixed cylinder.

[0014] These five features make the spring more securely fixed between the L-shaped plate and the moving plate, reduce direct wear of the spring on the L-shaped plate, accurately limit the position of the telescopic rod in the fixed cylinder, improve the reliability of the limit, make the movement of the moving plate more stable, avoid deviation affecting the limit effect, make the sliding guide of the moving plate more precise, further enhance the structural stability, and lock the insertion state of the limit rod and the telescopic rod to prevent accidental disengagement.

[0015] In a preferred embodiment, the inner wall of the fixed cylinder is provided with two vertically arranged guide grooves, and the outer wall of the telescopic rod is fixed with two guide blocks that are slidably connected to the guide grooves on the same side of the inner wall of the fixed cylinder.

[0016] In a preferred embodiment, the float, the fixed cylinder, and the telescopic rod are all located inside the tank. The top surface of the cover is provided with a slot that communicates with the inner cavity of the tank. The liquid level rod is slidably inserted into the slot on the top surface of the cover. The liquid level rod extends above the cover, and the front surface of the liquid level rod is provided with vertically arranged liquid level scale lines.

[0017] These two features make the telescopic rod move up and down more smoothly in the fixed cylinder, ensuring the continuity of liquid level monitoring and allowing the liquid level in the tank to be read directly above the cover, thus improving the convenience of monitoring.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model achieves accurate monitoring of the conductive slurry level in the tank by setting up a float, fixed cylinder, telescopic rod, and liquid level rod in the liquid level measuring mechanism; the float rises and falls with the liquid level, driving the telescopic rod to slide in the fixed cylinder, and then causing the liquid level rod to move in the slot of the cover. The liquid level scale line on the liquid level rod can intuitively show the liquid level height, achieving the effect of timely and accurate grasp of the conductive slurry level in the tank, providing a reliable basis for the rational use and control of conductive slurry in the production process, and effectively avoiding production errors or safety hazards caused by unclear liquid level;

[0020] 2. This utility model achieves stable limiting of the telescopic rod and float by setting two limiting components in the liquid level measuring mechanism. When the limiting rod passes through the through hole on the outer wall of the fixed cylinder and slides into the limiting hole on the outer wall of the telescopic rod, it can prevent excessive displacement of the telescopic rod and ensure the accuracy and stability of the liquid level measurement. At the same time, the synergistic effect of the L-shaped plate, spring, and moving plate gives the limiting components a certain buffering and adjustment capability, reducing the impact of liquid level fluctuations on the limiting structure. In addition, the two limiting components, together with the cover hinged to the tank body, facilitate the operation of the two limiting components inside the tank by the operator, achieving the effect of easy overall disassembly or installation of the float and telescopic rod, greatly saving the time and labor costs required for float disassembly, maintenance or replacement, improving equipment maintenance efficiency and ensuring the continuity of production.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-3 , Figures 5-6 As shown, the present invention provides a technical solution: a float device for monitoring the liquid level of a conductive slurry storage tank, including a liquid level measuring mechanism 3, a tank body 2, a cover 21 and a base plate 1. The liquid level measuring mechanism 3 is disposed inside the tank body 2, the tank body 2 is mounted on the top surface of the base plate 1, and the cover 21 is hinged to the top surface of the tank body 2. The liquid level measuring mechanism 3 includes a float 31, a fixed cylinder 32 located above the float 31, a telescopic rod 33 fixed on the top surface of the float 31 and slidably inserted into the fixed cylinder 32, and a liquid level rod 34 fixed on the top surface of the fixed cylinder 32 and slidably inserted into the cover 21.

[0033] The liquid level measuring mechanism 3, consisting of a float 31, a fixed cylinder 32, a telescopic rod 33, a liquid level rod 34, and a limiting component 36, combined with the tank body 2, the cover 21, and the bottom plate 1, enables liquid level monitoring and facilitates the disassembly and assembly of the float, thereby improving maintenance efficiency and saving costs.

[0034] The inner wall of the fixed cylinder 32 is provided with two vertically arranged guide grooves, and the outer wall of the telescopic rod 33 is fixed with two guide blocks 35 that are slidably connected to the guide grooves on the same side of the inner wall of the fixed cylinder 32.

[0035] The guide groove on the inner wall of the fixed cylinder 32 and the guide block 35 of the telescopic rod 33 ensure smooth lifting and lowering of the telescopic rod, avoid jamming, and ensure that changes in liquid level can be reflected in time by the liquid level rod 34, thus ensuring continuous monitoring.

[0036] The float 31, the fixed cylinder 32 and the telescopic rod 33 are all located inside the tank body 2. The top surface of the cover 21 is provided with a slot that communicates with the inner cavity of the tank body 2. The liquid level rod 34 is slidably inserted into the slot on the top surface of the cover 21. The liquid level rod 34 extends to the top of the cover 21, and the front surface of the liquid level rod 34 is provided with vertically arranged liquid level scale lines.

[0037] The liquid level is easily monitored by having a built-in float 31, fixed cylinder 32, telescopic rod 33, and liquid level rod 34 that engages with the slot of cover 21 and is marked, allowing the liquid level to be read directly from outside the tank. The structure is compact and does not take up extra space.

[0038] In this embodiment, as Figures 1-8 As shown, the liquid level measuring mechanism 3 also includes: two limiting components 36, symmetrically arranged on the outer wall of the fixed cylinder 32, used to limit the telescopic rod 33 and the float 31. The limiting component 36 includes an L-shaped plate 361 fixed on the outer wall of the fixed cylinder 32, a spring 363 with one end fixed on the outer wall of the vertical plate end of the L-shaped plate 361, a movable plate 364 fixed to the other end of the spring 363 and slidably connected to the horizontal plate end of the L-shaped plate 361, and a limiting rod 365 fixed on the outer wall of the movable plate 364 and slidably inserted into the telescopic rod 33. A fixing rod 368 is fixed on the front surface of the movable plate 364.

[0039] The limiting component 36 also includes a pad 362 fixed to the surface of the vertical end of the L-shaped plate 361 near the fixed cylinder 32, and a spring 363 fixed between the pad 362 and the movable plate 364 on the same side and arranged horizontally.

[0040] By using the shim 362 of the limiting component 36, the spring 363 is more firmly fixed between the L-shaped plate 361 and the moving plate 364, reducing the wear of the spring on the L-shaped plate, extending the service life of the component, and ensuring the stability of the limiting position.

[0041] The limiting rod 365 is fixed on the side surface of the same side moving plate 364 near the fixed cylinder 32. The outer wall of the fixed cylinder 32 is provided with two through holes that communicate with its inner cavity. The outer wall of the telescopic rod 33 is provided with two limiting holes that correspond to the positions and sizes of the same side through holes on the inner wall of the fixed cylinder 32. The limiting rod 365 passes through the same side through holes on the outer wall of the fixed cylinder 32 and slides into the same side limiting holes on the outer wall of the telescopic rod 33.

[0042] The cooperation between the limiting rod 365, the through hole of the fixed cylinder 32, and the limiting hole of the telescopic rod 33 ensures that the telescopic rod is precisely limited within the fixed cylinder, preventing excessive slippage and ensuring stable and reliable liquid level measurement.

[0043] The bottom surface of the horizontal end of the L-shaped plate 361 is provided with a limiting groove arranged horizontally. The top surface of the movable plate 364 is fixed with a movable block 366, and the top surface of the movable block 366 is fixed with a limiting block 367 that is slidably connected to the limiting groove on the bottom surface of the horizontal end of the L-shaped plate 361 on the same side.

[0044] The L-shaped plate 361 horizontal end limiting groove, the moving block 366 and the limiting block 367 make the moving plate 364 slide smoothly, avoid deviation, ensure the precise insertion of the limiting rod 365 and improve the limiting effect.

[0045] The longitudinal cross-sectional shape of the guide groove on the bottom surface of the horizontal plate of L-shaped plate 361 is I-shaped, and the shape of the limiting block 367 is I-shaped to match the shape of the guide groove on the bottom surface of the horizontal plate of L-shaped plate 361.

[0046] By adapting the I-shaped guide groove to the limiting block 367, the sliding guide of the moving plate 364 is more precise, preventing it from deviating from the track, and further enhancing the structural stability and operational reliability of the limiting component 36.

[0047] The front surface of the horizontal end of the L-shaped plate 361 is provided with two insertion holes arranged from left to right. The fixed rod 368 is L-shaped. The limiting component 36 also includes a screw 369 threadedly connected to the vertical end of the fixed rod 368, a rotating column 3610 coaxially fixed to the rear surface of the screw 369, a turntable 3611 coaxially fixed to the front surface of the screw 369, and a lever 3612 fixed to the front surface of the turntable 3611 near the edge. When the limiting rod 365 and the limiting hole on the same side of the outer wall of the telescopic rod 33 are slidably inserted together, the rotating column 3610 on the same side is slidably inserted together with the insertion hole on the front surface of the horizontal end of the L-shaped plate 361 near the fixed cylinder 32.

[0048] The L-shaped plate 361 insertion hole, fixing rod 368, screw 369, rotating column 3610, etc., can lock the insertion state of the limiting rod 365 and the telescopic rod 33 to prevent accidental disengagement and ensure that the limiting is effective for a long time.

[0049] In this embodiment, the tank 2 and the cover 21 are existing technologies, and their structure and working principle are as well known to those skilled in the art, and will not be described in detail here.

[0050] In this embodiment, when the liquid level of the conductive slurry in the tank changes, the float 31 rises and falls with the liquid level. Since the telescopic rod 33 is fixed to the fixed cylinder 32 through two limiting components 36, the fixed cylinder 32 drives the liquid level rod 34 to move synchronously. The liquid level can be read above the cover 21 through the scale on its surface.

[0051] In the limiting assembly 36, the spring 363 pushes the moving plate 364, so that the limiting rod 365 passes through the through hole of the fixed cylinder 32 and is inserted into the limiting hole of the telescopic rod 33, thereby fixing the telescopic rod 33 to the fixed cylinder 32. When the moving plate 364 moves, the limiting block 367 slides along the limiting groove at the horizontal end of the L-shaped plate 361 to ensure stability.

[0052] When the float 31 needs to be disassembled, first open the cover 21 that is hinged to the tank body 2, rotate the lever 3612 to drive the turntable 3611 and screw 369 to rotate, so that the rotating column 3610 disengages from the L-shaped plate 361 insertion hole, pull the fixing rod 368 to move the moving plate 364, and the limiting rod 365 disengages from the limiting hole of the telescopic rod 33, so that the float 31 and telescopic rod 33 can be removed; the operation is reversed during installation.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
