A type of anti-clogging linkage float level switch

Abstract

This invention provides an anti-clogging linkage float level switch, comprising a magnetic float, a junction box, a connecting rod, and a sleeve. The magnetic float is sleeved on the connecting rod, the junction box is installed at the upper end of the connecting rod, and the sleeve is cylindrical with an opening at the upper end and a closed lower end. The sleeve is fitted onto the magnetic float through the opening and can float up and down with the magnetic float. This anti-clogging linkage float level switch uses the sleeve to separate the connecting rod from the liquid, preventing suspended matter in the liquid from sticking to the surface of the connecting rod, which could cause the float to operate unevenly.

Description

Technical Field

[0001] This utility model relates to the field of mechanical structure technology, specifically to an anti-clogging linkage float level switch. Background Technology

[0002] A linkage float level switch (also known as a linkage float liquid level switch) is a liquid level control device based on the principles of buoyancy and magnetism, widely used in industrial liquid level monitoring and alarm systems. In existing linkage float level switches, the linkage is in direct contact with the liquid, and the float can float up and down along the linkage. When the liquid being measured contains suspended matter, it may adhere to the surface of the linkage. Over time, this adherence can hinder the movement of the float, even causing jamming, affecting the operation of the linkage float level switch and potentially leading to production accidents.

Detailed Implementation

[0018] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] like Figures 1-5 As shown, this utility model provides an anti-clogging linkage float level switch 100, including a magnetic float 1, a junction box 2, and a connecting rod 3. The magnetic float 1 is sleeved on the connecting rod 3, and the junction box 2 is installed at the top of the connecting rod 3. The anti-clogging linkage float level switch 100 also includes a sleeve 4, which is sleeved on the outer surface of the magnetic float 1.

[0020] In this embodiment, specifically: the magnetic float 1 is spherical or cylindrical in shape, with a hole 11 in the middle. The size of the hole 11 is such that the magnetic float 1 can move freely up and down while being fitted onto the connecting rod 3, while also limiting the magnetic float 1 from swinging too much in the vertical direction. Preferably, the ratio of the diameter of the hole 11 to the outer diameter of the connecting rod 3 is 1.02~1.05. The connecting rod 3 is cylindrical in shape, with a cavity along the axial direction inside. The upper end of the cavity is open, and the lower end is closed. A reed switch (not shown in the figure) is installed inside the cavity. The junction box 2 is rectangular in shape and communicates with the cavity of the connecting rod 3. The junction box 2 is provided with a connector 21 for installing signal wires. The sleeve 4 is cylindrical in shape and can be fitted onto the magnetic float 1, floating up and down with the magnetic float 1.

[0021] refer to Figure 2 As shown, a sealing element 6 is provided between the magnetic float 1 and the sleeve 4, and a clamp 7 is also provided on the outer wall of the sleeve 4. The clamp 7 can be tightened so that the sleeve 4 and the magnetic float 1 can be fixed together.

[0022] In this embodiment, specifically: the seal 6 is annular, the hole on the seal 6 is interference-fitted with the magnetic float 1, and the outer diameter of the seal 6 is interference-fitted with the opening on the sleeve 4. This prevents the magnetic float 1 from detaching from the sleeve 4 when the sleeve 4, seal 6, and sleeve 4 are assembled together. The seal 6 is made of soft, elastic rubber, providing good sealing. The clamp 7 is equipped with a connecting block 71 and a bolt 72. The bolt 72 is installed on the connecting block 71. Tightening the bolt 72 makes the sleeve 4, seal 6, and magnetic float 1 more securely fastened.

[0023] refer to Figures 2-4As shown, the connecting rod 3 is provided with a limiting member 31, which includes a first limiting ring 311 and a second limiting ring 312. The position of the first limiting ring 311 corresponds to the upper water level line, and the position of the second limiting ring 312 corresponds to the lower water level line. Inside the connecting rod 3, a reed switch (not shown in the figure) is provided at the position corresponding to the limiting member 31. When the magnetic float 1 moves to the position of the limiting member 31, the magnetic field on the magnetic float 1 will cause the reed switch corresponding to the limiting member 31 to respond, thereby outputting a signal to realize the function of opening or closing.

[0024] In this embodiment, specifically: the limiting member 31 is movable and its position on the connecting rod 3 can be adjusted. The limiting member 31 is provided with an adjusting bolt 313. By tightening and loosening the adjusting bolt 313, its position on the connecting rod 3 can be adjusted and fixed. In conjunction with the corresponding adjustment of the reed switch position inside the connecting rod 3, different requirements for the upper and lower limits of the liquid level in the control container can be met according to the site requirements.

[0025] refer to Figure 5 As shown, the contaminant-blocking assembly 5 includes a first flange 51 at the upper end and a second flange 53 at the lower end. A baffle 52 is provided between the first flange 51 and the second flange 53. The contaminant-blocking assembly 5 can isolate the exposed portion of the connecting rod 3 at the upper end of the magnetic float 1 from the outside environment, preventing contaminants mixed with water splashed from the liquid surface from adhering to the connecting rod 3. The first flange 51 is placed on the first limiting ring 311, and the baffle 52 is placed on the sealing element 6. When the magnetic float 1 floats up and down, the second flange 53 will move up and down with the magnetic float 1.

[0026] In this embodiment, specifically: the baffle 52 is a pleated waterproof cloth. When the distance between the first flange 51 and the second flange 53 changes, the baffle 52 can be adjusted through the pleats, without restricting the displacement between the first flange 51 and the second flange 53. The second flange 53 has a certain weight to prevent it from detaching from the seal 6 when the magnetic float 1 moves downward. When the first flange 51 has some contaminants adhering to it, the first flange 51 can be replaced to avoid the first flange 51 carrying contaminants becoming too heavy and affecting the up-and-down movement of the magnetic float 1.

[0027] The anti-clogging linkage float level switch 100 provided by this utility model can be used in a liquid containing suspended matter or contaminants. When placed in a liquid, the sleeve 4 is used to isolate the linkage 3 from the liquid, which can prevent the linkage 3 from contacting the liquid and causing inaccurate vertical displacement. By adding a contaminant blocking component 5, it can also prevent splashing droplets from carrying contaminants and sticking to the upper end of the linkage 3, ensuring that the vertical displacement of the magnetic float 1 is unobstructed.
