Description

Liquid level meter

Technical Field

The invention relates to a liquid level meter.

Background

The magnetic plate liquid level gauge is widely used for detecting and displaying the liquid level height of liquid in a chemical tank body, and particularly comprises a vertical barrel body attached to one side of the tank body, wherein the lower end of the barrel body is communicated with the tank body, so that the liquid in the tank body enters the barrel body, and the liquid level in the barrel body is the same as the liquid level in the tank body; a floater is arranged in the cylinder body, and a permanent magnet strip is arranged in the floater; a plurality of permanent magnet plates are vertically arranged on the outer side of the cylinder body, and each permanent magnet plate is rotatably arranged; the first plate surface of the permanent magnet plate is set to be white, and the second plate surface is set to be red; when the liquid level in the tank body changes and the liquid level in the cylinder body changes synchronously, the height of the floater changes synchronously, the permanent magnet plates are turned over under the action of magnetic force formed between the permanent magnet strips in the floater and the passing permanent magnet plates, and then the outer plate surfaces of the permanent magnet plates change to mark the height of the liquid level.

In the above-mentioned magnetic flap level gauge, the radial dimension of the float needs to be approximately equal to the inner diameter of the cylinder to prevent the float from generating radial play in the cylinder (if the float generates radial play, the magnetic force between the permanent magnet strips and the permanent magnet plate may be weakened, and the permanent magnet plate cannot be turned over).

However, when the tank and the liquid contained in the barrel have large particles of solute and the solvent is viscous, since the float occupies almost the entire cross section of the barrel, the large particles of solute may be caught between the float and the inner wall of the barrel so that the float cannot rise and fall with the liquid level.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.

The embodiment of the invention discloses a liquid level meter which is arranged in a tank body containing first liquid, and is particularly suitable for the tank body with a large height-diameter ratio and the liquid mixed with a large amount of particles in the first liquid.

As shown in fig. 1 to 3, the liquid level meter includes: the drum comprises a drum body 10, a winding drum 20, a permanent magnet plate 40, a first floater 31, a second floater 32, a permanent magnet strip 80, a first rope 51, a second rope 52 and a disc spring 60.

The cylinder 10 is disposed outside the tank and is vertically disposed, the lower end of the cylinder 10 is closed, and the cylinder 10 is used for containing a second liquid such as kerosene and the like without particles. The second liquid may be injected into the cylinder 10 through the upper end of the cylinder 10.

The winding drum 20 penetrates through the wall of the tank body, two ends of the winding drum 20 horizontally extend into the bottom of the tank body and the bottom of the barrel body 10, a bearing 71 is arranged at the penetrating position of the winding drum 20, and a sealing assembly 72 is arranged on one side of the tank body of the bearing 71 and used for preventing the first liquid from entering the barrel body 10.

The drum 20 winds a first cord 51 on the portion of the can that is located on the drum 10 and winds a second cord 52 on the portion of the can that is located on the drum 10.

A disc spring 60 is provided inside the spool 20, and the disc spring 60 is used to provide a restoring force.

The first floater 31 and the second floater 32 are made of the same material, the first floater 31 has a volume larger than that of the second floater 32, the second floater 32 is provided with a permanent magnet bar 80 therein, the second floater 32 is disposed in the cylinder 10, and the second floater 32 has a radial size approximately equal to the inner diameter of the cylinder 10, so that the second floater 32 does not generate a radial play in the cylinder 10.

The first float 31 is disposed in the tank, and the free end of the first rope 51 is connected to the bottom of the first float 31, and the free end of the second rope 52 is connected to the bottom of the second float 32.

The permanent magnet plates 40 are arranged outside the cylinder 10 vertically, and each permanent magnet plate 40 is arranged in a rotatable manner, so that when the second floater 32 moves to the height of one permanent magnet plate 40, the permanent magnet bars 80 and the permanent magnet plate 40 perform magnetic action to turn over the permanent magnet plates 40.

In the present invention, the winding directions of the first rope 51 and the second rope 52 are identical, and the length of the first rope 51 between the first floater 31 and the drum 20 and the length of the second rope 52 between the second floater 32 and the drum 20 are identical.

The working process of the liquid level meter provided by the invention is described as follows:

when the liquid level of the first liquid in the tank rises, the first float 31 rises, the second float 32 rises synchronously, and the permanent magnet plate 40 corresponding to the height of the first float 31 is turned over to indicate the height of the liquid level, which is the same as the height of the first float 31.

When the liquid level of the first liquid in the tank body descends, the first floater 31 descends along with the first liquid, the first rope 51 is straightened all the time by the resetting force of the disc spring 60, the second rope 52 is wound on the winding drum 20 synchronously with the first rope 51, the second floater 32 descends synchronously, and the permanent magnet plate 40 corresponding to the height of the first floater 31 overturns to mark the height of the liquid level, wherein the height of the permanent magnet plate is the same as the height of the first floater 31.

The liquid level meter provided by the invention has the advantages that:

utilize second float 32 to make the permanent magnet upset come the height of sign liquid level, because the second liquid in the barrel 10 does not have the particulate matter, this makes second float 32 can not die the card, and this makes when being applied to the jar body that holds the liquid that has the particulate matter, and the liquid level meter can not receive the influence of particulate matter.
