Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1-4, an ultrasonic level meter based on wireless communication technology comprises an isolation mechanism, wherein the isolation mechanism comprises an isolation cylinder 2 and an isolation member 3, an opening is arranged at the top of the isolation cylinder 2, the top of the isolation cylinder 2 is detachably arranged at the bottom of a detection part of the ultrasonic level meter 1 through the opening, and the isolation member 3 is arranged on the bottom and the side wall of the isolation cylinder 2 respectively.
When the ultrasonic material level meter is used, the isolation cylinder 2 with proper length is selected, the isolation cylinder 2 is arranged at the lower part of the ultrasonic material level meter 1, and the bottom of the isolation cylinder 2 is close to the bottom of a container. In this embodiment, the lower portion of the ultrasonic level meter 1 and the top of the isolation cylinder 2 are correspondingly provided with a threaded connection piece, and the isolation cylinder 2 and the ultrasonic level meter 1 are detachably connected through threads. The inside separator 3 and the isolation cylinder 2 intercommunication of passing through of container, the liquid in the container passes through the separator 3 and gets into in the isolation cylinder 2, and ultrasonic wave level meter 1 detects the liquid level position in the isolation cylinder 2. Because the liquid level area in the isolation cylinder 2 is small, and the isolation piece 3 is long, namely the communication position of the liquid level in the isolation cylinder 2 and the liquid level in the container is narrow, the influence of the liquid level fluctuation in the container on the liquid level in the isolation cylinder 2 is small, and the influence on the measurement of the ultrasonic level meter 1 can be fully reduced. Especially, the liquid level foam is generally produced by the notes liquid time, and the foam that the liquid level in the container produced can't get into in the insulating cylinder 2 in a large number under the isolation effect of separator 3, even a small amount of tiny foam gets into insulating cylinder 2, also can be in error range to the measurement of liquid level, can fully avoid the foam to the measurement influence of liquid level.
In practice, the spacer 3 is a filter screen. A strip-shaped opening 4 is formed in the side wall of the isolation cylinder 2 along the axial direction, an adjusting mechanism is arranged on the isolation cylinder 2 corresponding to the strip-shaped opening 4, and a plurality of side wall isolation pieces 3 are arranged on the adjusting mechanism in an adjustable mode. Generally, a viscous liquid does not easily generate foam, occasionally, bubbles with a small number but a large volume are generated, but the pore size of the filter screen is too small to facilitate the viscous liquid to pass through. Therefore, the number of the partition pieces 3 on the side wall is multiple, the partition pieces are respectively a plurality of layers of filter screens with different hole numbers, and different partition pieces 3 can be selected and used according to different liquid properties.
Specifically, the adjusting mechanism comprises a sliding groove 5 and a baffle 6, the baffle 6 is arranged on one side of the strip-shaped opening 4, and the multiple layers of sliding grooves 5 are arranged on the other side of the strip-shaped opening 4; the side wall isolating piece 3 comprises an isolating frame and a filter screen respectively, wherein the filter screen is arranged on the isolating frame, and the isolating frame is arranged in the sliding groove 5 in a sliding manner. A pull rope is arranged on one side of the isolation frame, is a thin flexible pull rope and is arranged on the side wall, facing the baffle 6, of the isolation frame. After the isolation frame slides out in the sliding groove 5 through the pull rope, the isolation frame can be manually pulled to move, the isolation piece 3 with less meshes is selected for liquid with higher viscosity, and the isolation piece 3 with more meshes is selected for liquid with low viscosity. The pulling isolation frame slides in spout 5 to make one side butt of isolation frame on baffle 6, because the stay cord is thin gentle stay cord, the isolation frame butt supports stay cord or partial stay cord to press between isolation frame and baffle 6 when baffle 6 is gone up, can not cause the influence to the contact of isolation frame and baffle 6, the isolation frame is close to the laminating mutually with baffle 6, spout 5 and other barrier member 3, avoid a large amount of, bulky foam to get into isolation cylinder 2 by the gap. In reality, a groove is formed in the baffle 6 corresponding to each layer of isolation frame, the frame edge of the isolation frame is in the groove when the isolation frame is abutted to the baffle 6, the size of the isolation frame is fitted with the groove, and the isolation frame can be prevented from moving under the action of non-manpower by friction force between the isolation frame and the groove wall.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
