Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, in particular to a liquid level gauge flushing device. Background Art

[0002] As we all know, liquid level refers to the height of a liquid medium in a container, and a liquid level gauge is an instrument used to measure the liquid level of the medium. Liquid level gauges are widely used in various fields such as electricity, pharmaceuticals, and chemicals. They are one of the most common measuring instruments, and the objects they measure are mostly liquid media.

[0003] However, after long-term use of the existing liquid level gauge, scale will be generated in its box. The existing liquid level gauge is not convenient to clean the scale in its box, the operation is cumbersome, a lot of time is wasted, and practicality is poor. In order to solve the above technical problems, the prior art proposes, for example, Chinese patent [application number CN202022556758.7] discloses a liquid level gauge box flushing device, which includes a shell, a water inlet pipe, a water outlet pipe, a water guide pipe, a suction pump, a first control valve, a second control valve, two sets of connecting pieces and a liquid level pipe. A channel is provided inside the shell, and the liquid level pipe is installed in the channel. The output end of the water inlet pipe passes through the right end of the shell and is connected to the liquid level pipe; although the patent can open the first control valve and the second control valve, and then open the suction pump, so that water in the external equipment enters the liquid level pipe through the water guide pipe, and then the water accelerates the flow speed under the action of the suction pump, so that the water flushes the inner wall of the liquid level pipe; however, the above patent has certain defects during use, such as scale adhering to the inner wall of the liquid level pipe, and relying solely on water flushing may result in the scale not being cleaned off. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a liquid level meter flushing device.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A liquid level gauge flushing device comprises a liquid level tube, one side of the liquid level tube is fixedly connected to a water inlet pipe and a water outlet pipe respectively, the top of the liquid level tube is fixedly connected to a connecting pipe, the inner top side of the connecting pipe is rotatably connected to a rotating rod, the bottom of the rotating rod is fixedly connected to a connecting plate, a cleaning brush is fixedly installed on one side of the bottom of the connecting plate, the cleaning brush fits against the inner wall of the liquid level tube, the outer surface of the rotating rod is fixedly connected to a baffle, the bottom of the liquid level tube is fixedly provided with a connecting flange, and a sealing flange is detachably connected to the connecting flange by bolts.

[0007] Preferably, the water inlet pipe and the water outlet pipe are both provided with a first valve.

[0008] Preferably, one end of the water inlet pipe and the water outlet pipe away from the liquid level pipe is fixedly connected with a mounting ring, a through hole is opened on one side of the mounting ring, and a fixing bolt is provided inside the through hole.

[0009] Preferably, a second valve is provided on the connecting pipe.

[0010] The beneficial effects of the present invention are as follows: the present invention provides a liquid level gauge flushing device. When using the device, the mounting ring is first brought into contact with the external equipment, and then the device is screwed to the external equipment through the fixing bolts. The water in the external equipment can enter the liquid level pipe through the water inlet pipe and the water outlet pipe, so that the water capacity in the external equipment can be known. When the liquid level pipe is used for a long time, scale will appear on its inner wall. At this time, the liquid level pipe needs to be flushed. The first valve can be closed, and then the connecting pipe can be connected to the external water source. The water enters the interior of the connecting pipe and then enters the interior of the liquid level pipe to flush the interior of the liquid level pipe. The water pushes the baffle during the flow, thereby driving the rotating rod to rotate, and then the connecting plate drives the cleaning brush to clean the inner wall of the liquid level pipe to prevent scale from adhering to the inner wall of the liquid level pipe. The sealing flange can be removed to discharge the impurities and water that have been cleaned. BRIEF DESCRIPTION OF THE DRAWINGS
