Description

Technical Field

[0001] The utility model relates to the technical field of float level gauges, in particular to a float level gauge with antifreeze and heat preservation functions. Background Art

[0002] The float level gauge is a liquid level measuring instrument designed based on Archimedes' law and magnetic coupling principle. The instrument can be used to measure liquid level, boundary level and density, and is responsible for the output of upper and lower limit alarm signals. It is specially used to measure the liquid level in pressure vessels. Liquid will solidify at low temperatures. Once the liquid in the float solidifies, the float level gauge can no longer accurately detect the liquid level in the container. In order to prevent the liquid from solidifying, the float level gauge needs to be antifreeze and heat-insulated.

[0003] In the prior art, most of the float level gauges with antifreeze and heat preservation functions are realized by direct steam. For example, the patent publication number is CN208860445U, which is a direct steam heating float level gauge. The float level gauge directly introduces low-pressure steam from the bottom of the float level gauge, and controls the steam flow rate to achieve the purpose of not affecting the measurement of the level gauge while playing the role of heating and flushing the float level gauge, thereby achieving the dual purposes of heating, antifreeze and anti-crystallization and flushing the float level gauge, and providing a guarantee for the long-term stable operation of the system.

[0004] The above patent has certain drawbacks. When flushing the inner wall of the liquid level gauge cylinder, it is sometimes difficult to clean the stains on the inner wall of the liquid level gauge cylinder by relying solely on steam flushing, resulting in incomplete cleaning of the inner wall of the cylinder, affecting the normal use of the liquid level gauge. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a float level gauge with antifreeze and heat preservation functions, which can clean the stains on the inner wall of the cylinder, make the inner wall of the cylinder clean more thoroughly, and ensure the normal use of the level gauge.

[0006] Technical Solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a floating cylinder liquid level gauge with antifreeze and heat preservation functions, comprising a liquid level gauge cylinder and a cleaning mechanism, wherein a liquid inlet pipe and a liquid outlet pipe are symmetrically connected on one side of the outer side of the liquid level gauge cylinder, and a butt flange is connected to the liquid inlet pipe and the liquid outlet pipe, a liquid level gauge lower flange is arranged at the bottom of the liquid level gauge cylinder, and a liquid level gauge upper flange is arranged at the top of the liquid level gauge cylinder, the bottom of the liquid level gauge cylinder is connected to a steam pipeline through the liquid level gauge lower flange, and the top of the liquid level gauge cylinder is connected to a steam pipeline through the liquid level gauge upper flange. The flange is connected to a liquid level transmitter, the cleaning mechanism includes a driving shaft, a support plate is fixedly connected to the bottom of the inner wall of the liquid level meter cylinder, the driving shaft is rotatably installed on the support plate, a plurality of groups of steam blades are evenly fixedly provided on the outer wall of the bottom of the driving shaft, a connecting plate is fixedly connected to the top of the driving shaft, two groups of cleaning plates are symmetrically fixedly connected to the top of the connecting plate, a plurality of groups of bristles are evenly provided on the outer walls of the two groups of cleaning plates, a drain pipe is connected to the outer wall of the bottom of the liquid level meter cylinder near the lower flange of the liquid level meter, and a drain valve is arranged on the drain pipe.

[0008] Preferably, reinforcing rods are fixedly connected between the inner sides of the two groups of cleaning plates and the top ends of the connecting plates.

[0009] Preferably, sealing gaskets are fixedly connected to both sets of the butt flanges.

[0010] Preferably, the top end of the lower flange of the liquid level gauge and the bottom end of the upper flange of the liquid level gauge are both annularly and equidistantly fixedly connected to the outer wall of the cylinder of the liquid level gauge by three groups of ribs.

[0011] Preferably, the steam blades and the cleaning plate are made of corrosion-resistant plastic material.

[0012] Compared with the prior art, the utility model has the following beneficial effects: when the inner wall of the cylinder of the liquid level gauge is flushed by steam, the steam flow entering the float liquid level gauge is controlled by the flow control device on the steam pipe, and the steam flow is appropriately increased. When the steam enters the cylinder of the liquid level gauge, the steam impacts the steam blades, driving the steam blades to rotate, so that the steam blades drive the driving shaft to rotate, and the driving shaft drives the connecting plate to rotate, so that the connecting plate drives the cleaning plate to rotate, and the rotation of the cleaning plate drives the bristles to brush the inner wall of the cylinder of the liquid level gauge, thereby scraping away the stubborn stains attached to the inner wall of the cylinder of the liquid level gauge. After cleaning, the steam pipe at the bottom of the cylinder of the liquid level gauge is closed, and then the drain valve is opened to discharge the sewage, so that the stains on the inner wall of the cylinder can be cleaned off, so that the inner wall of the cylinder can be cleaned more thoroughly, ensuring the normal use of the liquid level gauge.

After cleaning, the steam pipe at the bottom of the liquid level gauge cylinder 1 is closed, and then the drain valve 14 is opened to discharge the sewage, so that the stains on the inner wall of the cylinder can be cleaned off, so that the inner wall of the cylinder can be cleaned more thoroughly, ensuring the normal use of the liquid level gauge.
