Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, and more specifically to an anti-corrosion type liquid level gauge. Background Art

[0002] Liquid level refers to the height of the liquid level in a sealed container or an open container. The existing liquid level is monitored and measured by a liquid level gauge. The magnetic flap liquid level gauge (also called a magnetic float liquid level gauge) is developed based on the buoyancy principle and magnetic coupling. When the liquid level in the measured container rises or falls, the magnetic float in the liquid level gauge body tube also rises or falls. The permanent magnet in the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flip columns to flip 180°. When the liquid level rises, the flip column changes from white to red, and when the liquid level drops, the flip column changes from red to white. The red and white junction of the indicator is the actual height of the liquid level inside the container, thereby achieving a clear indication of the liquid level.

[0003] When the above scheme is implemented, the float is directly pushed up and down by the liquid, thereby driving the magnetic flip column indicator to flip through the permanent magnet inside the float. The existing liquid level meter is difficult to maintain, resulting in the liquid corroding the float of the liquid level meter when used for a long time, seriously affecting the service life of the device. A solution to the above problem is proposed below. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an anti-corrosion liquid level gauge, which can solve the problem that the magnetic flap liquid level gauge is easy to corrode due to the inconvenience of cleaning.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A corrosion-resistant liquid level gauge comprises a liquid level gauge tube, a magnetic column indicator is arranged on one side of the liquid level gauge tube, a float is arranged inside the liquid level gauge tube body, a permanent magnet is arranged inside the float, a first pipe is passed through the bottom of the side surface of the liquid level gauge tube, a second pipe is passed through the top of the side surface of the liquid level gauge tube, a first valve is respectively installed on the first pipe and the second pipe, a sealing cover is respectively installed on the top and bottom of the liquid level gauge tube, an annular weight block is arranged inside the liquid level gauge tube, a cleaning brush is respectively provided on the outer side and inner side of the weight block, a traction rope is installed on the top of the weight block, the traction rope passes through the sealing cover located at the top of the liquid level gauge tube, and the traction rope and the sealing cover located at the top of the liquid level gauge tube are slidably matched.

[0007] Preferably, a drain pipe for draining the liquid inside the liquid level gauge tube is provided on the sealing cover at the bottom of the liquid level gauge tube, and a second valve for sealing is installed on the drain pipe.

[0008] Preferably, an opening corresponding to the traction rope is provided on the sealing cover located at the top of the liquid level gauge tube, and a receiving ring is fixedly connected to the sealing cover with the opening, the opening is located inside the receiving ring, and the outside of the receiving ring is connected to a cover body through a thread, a bracket fixedly connected to the corresponding sealing cover is provided on one side of the opening, and the bracket is located inside the receiving ring, and the traction rope passes through the opening and is wrapped around the bracket.

[0009] Preferably, one end of the first pipeline and the second pipeline are respectively connected with a connecting flange for connecting to an external device.

[0010] Preferably, two traction ropes are provided, and the length of the traction rope is longer than the length of the liquid level meter tube.

[0011] Preferably, the lateral length of the float is smaller than its longitudinal length.

[0012] Preferably, a recess for placing a weight block is provided at the bottom of the sealing cover located at the top of the liquid level gauge tube, and the depth of the recess is greater than the thickness of the weight block.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. This solution connects the first pipe and the second pipe to the side of the container to be tested. The solution inside the container will enter the liquid level meter tube through the second pipe, and the air inside the liquid level meter tube will be discharged into the container. Using the principle of communicating vessels, the liquid level inside the container will be the same height as the liquid level inside the container. The buoyancy of the solution on the float will drive the float to move upward synchronously, and at the same time drive the permanent magnet inside the float. The permanent magnet is transmitted to the magnetic flip column indicator through magnetic coupling during the rising process, driving the red and white flip columns to flip 180°. When the liquid level rises, the flip column changes from white to red, and when the liquid level drops, the flip column changes from red to white. The red and white junction of the indicator is the actual liquid level inside the container. Height. When regular maintenance is required, the user first closes the first valve on the first pipe and the second pipe, opens the bottom of the level gauge through the sealing cover at the bottom of the level gauge tube, and discharges the excess solution inside the level gauge tube. Then, by releasing the traction rope, the traction rope removes the traction force on the weight block, and the weight block moves downward, thereby driving the bristles to move downward. The bristles will clean the inner side of the level gauge tube, and because the weight block is annular, the float will pass through the middle hole of the weight block, and the bristles inside the middle hole of the weight block will clean the float at the same time, avoiding the problem that traditional level gauges are inconvenient to clean the inner wall of the level gauge tube and the float, thereby achieving corrosion protection and increasing service life.

[0015] Second, the drain pipe is convenient for discharging the solution inside the liquid level meter tube without opening the sealing cover. The opening and closing of the drain pipe is controlled by the second valve, which is easy to use.

[0016] 3. The opening is convenient for the traction rope to pass through, and it is also convenient for adding cleaning liquid to the inside of the liquid level meter tube. The bracket is used to wrap the traction rope to avoid the problem of knotting and inconvenience caused by the traction rope falling. The receiving ring and the cover body seal the opening to avoid the influence of impurities.

[0017] 4. Flanges are used to facilitate connection with external containers.

[0018] 5. The use of two traction ropes can ensure the stability of the movement of the weight block. At the same time, the length of the traction rope is greater than the length of the liquid level gauge tube, which can ensure that the weight block moves to the bottom of the liquid level gauge tube, thereby achieving all-round cleaning of the inner side of the liquid level gauge tube.

[0019] 6. The horizontal length of the float is greater than the longitudinal length to prevent the float from rotating on the vertical plane inside the level gauge tube, ensuring the coordination effect between the permanent magnet and the magnetic column indicator.

[0020] 7. The notch is used to store the weight block to prevent the weight block from being inside the liquid level gauge tube, thereby ensuring the normal use of the liquid level gauge tube. BRIEF DESCRIPTION OF THE DRAWINGS
