Description
Technical Field
[0001] This utility model relates to the field of liquid level control switch technology, and in particular to a liquid level control structure for a wool wastewater transfer device. Background Technology
[0002] Wool wastewater transfer equipment, also known as wastewater lift pumps, is mainly used to lift wastewater from a lower level to a higher level, or to transport it from one area to another, so that it can enter the wastewater treatment system or the next treatment stage. Figure 1 As shown, existing sewage lift pumps mainly include a collection tank, which is equipped with an inlet pipe and an outlet pipe. Water is pumped through the inlet and outlet pipes. The pump is controlled by a control cabinet at the top of the collection tank and a float level switch inside the tank. The float level switch primarily detects the water level inside the collection tank by monitoring the movement of the float. Specifically, as... Figure 3 As shown, when the float of the float switch is not in contact with the water surface, the float hangs down at one end under its own weight. In this state, water continues to flow in through the inlet pipe. As the water level rises, the water surface overflows the float, causing it to float. Figure 2 As shown, the buoyancy force adjusts the float from a vertical state to a horizontal state. When the float is in this state, the water inlet pipe will stop supplying water.
[0003] Current technical problems: Because wool wastewater contains a large amount of grease, fiber, suspended solids and organic matter, it is easy to be adsorbed on the float, which makes the weight of the float gradually increase. Often, more buoyancy is required to make it drive the connecting rod to rotate to a horizontal position. More buoyancy means that a higher water level is required so that the water fully submerges the float. As a result, the actual water level will be higher than the preset water level, causing a decrease in the accuracy of water level control. Utility Model Content

[0030] like Figure 2 and Figure 3 As shown, a liquid level control structure for a wool wastewater transfer device includes a float level switch. The liquid level control structure also includes a movable ring 12, a driving component, and a cleaning component disposed on the inner wall of the movable ring 12. The driving component is used to drive the movable ring 12 to move along the outer surface of the float 9 during the process of the movable ring 12 being sleeved on the outer surface of the float 9 of the float level switch, so that the cleaning component cleans the outer surface of the float 9.
[0031] The above technical solution enables automatic cleaning of the float 9, preventing fibers, suspended matter, and organic matter from adhering to the float. During use, the drive component is activated, which drives the movable ring 12 to move along the surface of the float 9, thereby causing the cleaning component on the inner wall of the movable ring 12 to move synchronously. The cleaning component removes the fibers, suspended matter, and organic matter adhering to the surface of the float 9, restoring the mass of the float 9 to normal. This prevents the increased mass of the float 9 from requiring greater buoyancy to float, which could lead to a large difference between the actual water level and the detected water level, thus improving the accuracy of liquid level control.
[0032] like Figure 2 and Figure 3 As shown, in this embodiment, a hinge seat 7 is provided at one end of the float seat 5. The hinge seat 7 is rotatably connected to the rotating shaft 6, and the rotating shaft 6 is fixedly connected to one end of the connecting rod 8. The driving component includes a telescopic rod 11 whose base is fixedly connected to the float seat 5, and whose output end is fixedly connected to the movable ring 12. Specifically, a first connecting block 10 is provided at one end of the float seat 5, and the base of the telescopic rod 11 is fixed on the first connecting block 10. Preferably, the telescopic rod 11 can be a cylinder or an electric push rod.

[0036] As shown in Figure 2 and Figure 3 , in the embodiment, a through groove 14 is arranged at the bottom end of the movable ring 12, through which the connecting rod 8 of the liquid level switch passes.
[0037] The technical scheme can ensure that the movable ring 12 can be accommodated at one end of the floating ball seat 5 when the movable ring 12 is not used, so as to reduce the volume and not interfere with the rotation of the connecting rod 8.
[0038] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , in the embodiment, the liquid level control structure further comprises a flushing assembly for flushing the wet cleaning component; specifically, the flushing assembly comprises: a piston cylinder 18 provided with a water inlet hole 19 and a water outlet hole 21, one end of the piston cylinder 18 being fixedly connected with the movable ring 12; a one-way valve arranged in the water inlet hole 19 and the water outlet hole 21; a piston 17 movably arranged in the piston cylinder 18; a piston rod 16 having one end fixedly connected with the piston 17, the other end of the piston rod 16 being fixedly connected with the floating ball seat 5 of the liquid level switch; a water inlet pipe 20 connected with one end of the water inlet hole 19; a water outlet pipe 22 connected with one end of the water outlet hole 21; a spray head 23 fixedly connected with the other end of the water outlet pipe 22, the spray hole of the spray head 23 pointing to the cleaning component; preferably, one end of the floating ball seat 5 is provided with a second connecting block 15, the second connecting block 15 being fixedly connected with one end of the piston rod 16, and the inner diameter of the end of the movable ring 12 close to the spray head 23 is larger than that of the other end, so as to form a horn-shaped flow guide slope for guiding the water flow.
[0039] The above technical scheme can rinse and wet the bristles 13, so that the bristles 13 better clean the floating ball 9, when the telescopic rod 11 drives the movable ring 12 to reciprocate along the surface of the floating ball 9, the movable ring 12 drives the piston cylinder 18 to reciprocate relative to the piston rod 16, so that the piston 17 at one end of the piston rod 16 reciprocates in the piston cylinder 18, when the piston 17 gradually moves away from the water outlet hole 21, negative pressure is generated in the piston cylinder 18, sewage is introduced into the piston cylinder 18 through the water inlet pipe 20 and the water inlet hole 19, when the piston 17 gradually moves close to the water outlet hole 21, high pressure is generated in the piston cylinder 18, so that the water in the piston cylinder 18 is sprayed out through the water outlet hole 21, the water outlet pipe 22 and the spray head 23, the spray head 23 sprays the bristles 13 to wet them, according to the need, multiple spray heads 23 can be arranged in series with the water outlet pipe 22, so that the spray head 23 can flush the bristles 13 without dead angle, preventing the bristles 13 from accumulating dirt to affect the cleaning effect.

[0042] When the telescopic rod 11 drives the movable ring 12 to reciprocate along the surface of the floating ball 9, the movable ring 12 drives the piston cylinder 18 to reciprocate relative to the piston rod 16, so that the piston 17 at one end of the piston rod 16 reciprocates in the piston cylinder 18, when the piston 17 gradually moves away from the water outlet hole 21, negative pressure is generated in the piston cylinder 18, sewage is introduced into the piston cylinder 18 through the water inlet pipe 20 and the water inlet hole 19, when the piston 17 gradually moves close to the water outlet hole 21, high pressure is generated in the piston cylinder 18, so that the water in the piston cylinder 18 is sprayed out through the water outlet hole 21, the water outlet pipe 22 and the spray head 23, the spray head 23 sprays the bristles 13 to wet them, according to the need, multiple spray heads 23 can be arranged in series with the water outlet pipe 22, so that the spray head 23 can flush the bristles 13 without dead angle, preventing the bristles 13 from accumulating dirt to affect the cleaning effect.
