Description

Technical Field

[0001] The utility model relates to the technical field of liquid level detection equipment, in particular to a float liquid level gauge with a filtering function. Background Art

[0002] At present, there are many ways to measure liquid level on site, such as differential pressure level gauge, two-color water level gauge, etc., which are connected to the tank to be tested and use the principle of communicating vessels to make the liquid level in the measuring instrument equal to the liquid level in the tank to be tested, thereby achieving real-time liquid level measurement. A float level gauge is a common liquid level detection instrument. The common float level gauge includes a float and a measuring tube for placing the float. When the liquid level in the tank to be tested changes, the float in the float level gauge will move up and down with the change of the liquid level in the tank to be tested.

[0003] At present, due to the large amount of steel slag in the liquid in the tank to be tested of the steel plant, the steel slag and other impurities in the liquid will adhere to and deposit on the inner wall of the measuring tube of the float-type liquid level gauge, affecting the transparency of the measuring tube and the normal on-site reading of the float-type liquid level gauge. In addition, after the steel slag and other impurities in the liquid adhere to the inner wall of the measuring tube, the distance between the float and the inner wall of the measuring tube will be reduced, which can easily cause the float to be stuck at the impurity attachment point on the inner wall of the measuring tube, affecting the normal indication of the float-type liquid level gauge, making it difficult for on-site personnel to accurately understand the liquid level in the tank to be tested, which brings great safety hazards to steel production.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of description and are not used to limit the scope of the implementation of the present utility model. Changes or adjustments to their relative relationships should be regarded as the scope of the implementation of the present utility model without substantially changing the technical content.

[0024] like Figures 1 to 4As shown, the utility model provides a float level gauge with a filtering function, including a float level gauge body 2 and a filter 3, the filter 3 is connected to the float level gauge body 2, the filter 3 includes a filter pipe 12, an iron core 10 and a filter screen 7, the iron core 10 and the filter screen 7 are both arranged in the filter pipe 12, and the filter screen 7 at least partially covers the cross section of the filter pipe 12. By setting the iron core 10, the iron slag in the liquid can be removed by utilizing the magnetic force of the iron core 10, and the impurities in the liquid can be removed by setting the filter screen 7, which greatly reduces the impurities in the liquid entering the float level gauge body 2, avoids the impurities from adhering to and depositing on the pipe wall of the float level gauge, and improves the service life of the float level gauge, reduces the cost of the inspection and maintenance of the float level gauge, and improves its stability during use, which has good commercial value. In this embodiment, the filter screen 7 completely covers the cross section of the filter pipe 12, and the filtering effect is good.

[0025] The filter 3 includes a first connection seat 9, which is detachably arranged on the filter pipe 12, and the iron core 10 is arranged on the first connection seat 9. By arranging the iron core 10 on the first connection seat 9, after using the float level gauge for a period of time, the iron core 10 can be easily taken out to clean the steel slag adsorbed on the iron core 10. In this embodiment, the first connection seat 9 is threadedly connected to the filter pipe 12. An annular seal is arranged at the connection between the first connection seat 9 and the filter pipe 12, and the annular seal can be an O-ring 8. Figure 3 and Figure 4 As shown, in some embodiments, since some production lines in steel plants are in a high-temperature environment, the annular seal can be a metal winding pad 13, and the float in the float level gauge body 2 is a magnetic float level gauge to indicate the liquid level in the tank body 1 to be measured in a high-temperature environment.

[0026] Specifically, a covering sleeve 11 covering the iron core 10 is provided on the first connecting seat 9, and the covering sleeve 11 and the first connecting seat 9 form a containing space, and the iron core 10 is contained in the containing space.

It is prevented that the steel slag is directly adsorbed on the iron core 10, and it is difficult to remove the steel slag when the iron core 10 is cleaned. In this embodiment, the covering sleeve 11 is detachably connected to the first connecting seat 9, so that the covering sleeve 11 can be removed and reused when the iron core 10 is cleaned, thereby saving the use cost of the float level gauge.

By arranging the first connection seat 9 at the inflection point of the U, it is convenient to clean up various solid impurities in the liquid after they are deposited. When the solids are deposited during the flow in the filter 3, due to the influence of gravity, they are generally deposited at the lowest position of the U-shaped filter pipe 12, that is, the inflection point of the U.

[0028] The filter 3 includes a second connection seat 6, a filter screen 7 is arranged on the second connection seat 6, and the second connection seat 6 is detachably connected to the filter pipe 12. By providing the second connection seat 6, the filter screen 7 can be cleaned or replaced through the second connection seat 6, and the operation is convenient. In this embodiment, the second connection seat 6 is threadedly connected to the filter pipe 12. Through the threaded connection, the structure is simple, and it is easy to process and assemble.

[0029] Specifically, the filter screen 7 is cylindrical. The cylindrical filter screen 7 can filter the liquid multiple times, and the cylindrical filter screen 7 is easy to install and remove from the filter pipe 12.

[0030] In this embodiment, the float level gauge includes a filter screen retainer 4 and a fixing screw 5, and the second connecting seat 6 has a rod-shaped connecting portion, which passes through the filter screen 7 along the axial direction of the filter screen 7. Along the axis of the filter screen 7, one end of the filter screen 7 abuts against the second connecting seat 6, and the other end of the filter screen 7 abuts against the filter screen retainer 4, and the filter screen retainer 4 is fixed to the connecting portion by the fixing screw 5. The above connection method has a simple structure and is easy to produce and assemble.

[0031] In summary, by providing the iron core 10 and utilizing the magnetic force of the iron core 10, the steel slag in the liquid can be removed, and by providing the filter screen 7, the impurities in the liquid can be removed, thereby greatly reducing the impurities in the liquid entering the float level gauge body 2, and preventing the impurities from adhering to and depositing on the tube wall of the float level gauge, thereby increasing the service life of the float level gauge, reducing the cost of inspection and maintenance of the float level gauge, and improving its stability during use, thereby having good commercial value.

[0032] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
