Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-4, the utility model provides a flotation column liquid level measuring device, which comprises a flotation column container 1 and a mounting bracket 2 fixedly mounted on the flotation column container 1, wherein as shown in fig. 1, the mounting bracket 2 is L-shaped, and a diagonal brace 11 is mounted at a corner of the mounting bracket 2 to prevent the mounting bracket 2 from deforming;

a liquid level transmitter 3 and a detection rod 4 which are fixedly connected with the mounting bracket 2 are arranged right above the flotation column container 1, and the detection rod 4 is positioned right below the liquid level transmitter 3 and is vertical as shown in figure 1; smooth cover has smooth ball 5 on measuring pole 4, smooth ball 5 is located the top of foam blanket 13, smooth ball 5 with float 10 fixed connection on 12 liquid levels in ore pulp layer, the design like this, smooth ball 5 just does not receive the influence of ore grain when sliding on measuring pole 4, because smooth ball 5 is located the top of foam blanket 13, the ore liquid in foam blanket 13 and ore pulp blanket 12 can not glue on measuring pole 4, more can not appear ore grain gathering on measuring pole 4's surface and influence smooth ball 5 and slide, the later maintenance is simple and convenient, need not frequently clean and wash measuring pole 4, time saving and labor saving.

As shown in fig. 1, in order to further prevent the mineral liquid from sticking to the detection rod 4, a baffle 8 can be fixedly installed at the lower end of the detection rod 4, the baffle 8 is located above the foam layer 13, and the baffle 8 can effectively prevent the splashed mineral liquid from sticking to the detection rod 4, so that the sliding ball 5 can normally slide on the detection rod 4 for a long time.

In order to avoid the influence of the disturbance of the medium in the flotation column on the measurement accuracy, the baffle 8 is preferably fixedly connected with the inner wall of the flotation column container 1, as shown in fig. 1, in such a design, the upper end and the lower end of the detection rod 4 are fixed, the sliding ball 5 cannot swing transversely, and can only slide up and down along the detection rod 4, and the floater 10 fixedly connected with the sliding ball 5 cannot swing transversely, and can only slide up and down along the detection rod 4, which is beneficial to ensuring the measurement accuracy.

As shown in fig. 2-4, in order to further enhance the restriction of the float 10, so that the float can only slide up and down along the detection rod 4 without being affected by the disturbance of the medium in the flotation column, the sliding ball 5 and the float 10 are fixedly connected through the connecting rod 6 and the insertion tube 9, the connecting rod 6 is horizontal, the insertion tube 9 is vertical, one end of the connecting rod 6 is fixedly connected with the sliding ball 5, the other end of the connecting rod is fixedly connected with the upper end of the insertion tube 9, the lower end of the insertion tube 9 is inserted into the float 10 and fixedly connected with the float 10, the guide rod 7 is slidably inserted into the insertion tube 9, the upper end of the guide rod 7 extends out of the upper end of the insertion tube 9 and is fixedly connected with the mounting bracket 2, and since the lower end of the insertion tube 9 is inserted into the float 10, the ore slurry cannot enter the insertion tube 9, and the ore.

Considering that the particles will gather on the upper surface of the float 10 and affect the measurement accuracy, as shown in fig. 1, the float 10 is preferably of a drop-like structure, and when the float 10 floats on the liquid surface of the slurry layer 12, only the top tip of the upper portion protrudes out of the liquid surface, and most of the float 10 is located under the liquid surface, which avoids that the particles in the foam layer 13 are too much adhered to the float 10 to change the weight of the float 10 and affect the final measurement accuracy.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
