In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.
The present invention will be further described with reference to the accompanying drawings and preferred embodiments.
The first embodiment is as follows:
as shown in fig. 1 and 2, the device for detecting the depth of the clear water layer of the concentrating tank of the coal preparation plant comprises a siphon 1 and a mounting seat 2.
The siphon 1 comprises a water inlet end 6, a communication end 7 and a water outlet end 8 which are detachably connected, a water inlet of the water inlet end 6 is positioned below the liquid level of the concentration tank 3, and a water outlet of the water outlet end 8 is positioned above the liquid level of the overflow tank 4 and below the liquid level of the concentration tank. By means of siphoning, the water in the thickening tank 3 flows through the siphon 6 to the overflow launder 4. Meanwhile, the interior of the concentration tank 3 is sequentially layered into a clarification zone, a sedimentation zone, a transition zone and a compression zone from top to bottom. When the water inlet is positioned in the clarification area, the water outlet is clean water. When the water inlet is positioned in the settling zone, the water outlet is water with materials. That is to say, according to the water condition difference, monitor whether the water inlet is located clarification district or settlement district, in time adjust other parameters such as concentrated quick-witted pan feeding, the medicine volume that adds to ensure the degree of depth in clarification district.
