Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high sensitivity float-type liquid level indicating device.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of float-type liquid level indicating device comprises the container that liquid is housed; Be provided with support plate on described container, two pulleys are installed on the horizontal line of support plate, one of them pulley is positioned at the shell inboard, and another pulley is positioned at the shell outside; One end of connecting line connects the floating drum that is positioned at container, and the other end is connected with the liquid level indicator dog after walking around pulley; Liquid level scale be arranged on container outer wall or mint-mark on container outer wall.Described floating drum is cylindrical, by corrosion resistant nonmetallic materials, is made; Floating drum is comprised of cylindrical shell and cover, and cylindrical shell adopts screw thread or flange seal to be connected with cover, and the liquid of 40-60% volume is housed in floating drum, and the height of floating drum 1/2-2/3 immerses in the liquid in container.The core of described pulley is equipped with rolling bearing, and the inner ring of rolling bearing is fixed on the back shaft of support plate; Pulley also can directly consist of rolling bearing.Described connecting line is nylon wire, and indicator dog is isosceles triangle.The scale mark of described Liquid level scale is drawn with fluorescent pigment, in order to read liquid level evening.Be provided with by floating drum one side the dividing plate that bottom is communicated with in described container, in order to stablize liquid level, the impact of liquid fluctuating on the liquid level indication while reducing the container feed liquor.
The beneficial effects of the utility model are:
1, floating drum adopts detachable structure, and the inside carrying liquid, make the center of gravity of floating drum lower, easily keeps vertical state in container, thereby in receptor, the liquid fluctuating impact is less, has guaranteed that floating drum moves up and down neatly with the variation of liquid level in container.
2,, by the liquid that adds different densities in floating drum or the filling weight of adjusting liquid in floating drum, can make the liquid level indication of the applicable liquids having different specific weight of this level instruction device.
3, the core of pulley is equipped with rolling bearing, greatly reduces the lifting resistance of connecting line and liquid level indicator dog, has improved the sensitivity of device, and can effectively avoid the liquid level misdirection phenomenon caused because of the pulley clamping stagnation.
4, the Liquid level scale indicated with fluorescent pigment is set, facilitates the round-the-clock liquid level that reads.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of embodiment 2.
Fig. 3 is the structural representation of floating drum.
Embodiment
Embodiment 1 is as shown in Figure 1,3: a kind of float-type liquid level indicating device comprises the container 7 that liquid is housed; Be provided with support plate 3 in the upper end of described container 7, two pulleys 4 are installed on the horizontal line of support plate 3, one of them pulley 4 is positioned at the inboard of container 7 limit wall extended lines, and another pulley 4 is positioned at the outside of rustless steel container 7 limit wall extended lines; One end of connecting line 2 connects the floating drum 1 be positioned at container 7, and the other end of walking around after pulley 4 is connected with the liquid level indicator dog 5 of Liquid level scale 6 sides; Liquid level scale 6 is arranged on the outside of container 7 limit walls or mint-mark on container 7 limit walls.Described floating drum 1 is cylindrical, by corrosion resistant nonmetallic materials, is made; Floating drum 1 is comprised of cylindrical shell 10 and cover 9, and cylindrical shell 10 adopts screw thread or flange seal to be connected with cover 9, and 50% liquid is housed in floating drum 1, and the 1/2-2/3 of floating drum 1 highly immerses in the liquid in container 7.The core of described pulley 4 is equipped with corrosion resistant rolling bearing, and the inner ring of rolling bearing is fixed on the back shaft of support plate 3, greatly reduces the lifting resistance of connecting line 2 and liquid level indicator dog 5, has improved the sensitivity of device; Pulley 4 also can directly consist of rolling bearing.Described connecting line 2 is nylon wire, and indicator dog 5 is isosceles triangle.The scale mark of described Liquid level scale 6 is drawn with fluorescent pigment, in order to read liquid level evening.Be provided with by floating drum one side the dividing plate 8 that bottom is communicated with in described container 7, in order to stablize liquid level, the impact of liquid fluctuating on the liquid level indication while reducing container 7 feed liquor.
Embodiment 2 is as shown in Figure 2: the float-type liquid level indicating device of the present embodiment is for the level gauging of ammonium molybdate solution; Ammonium molybdate solution is comparatively valuable, the top cover of container 7 can not perforate through the connecting line of level gauge, enter the storage tank foul solution with impurity such as rainwater-proofs.For this reason, in the upper side of container 7, an angle square tube 11 is set, the rolling bearing inner ring of pulley 4 cores is fixed on the back shaft of angle square tube 11 inwalls.Floating drum 1 is cylindrical, by duroplasts, is made, and floating drum cylindrical shell 10 adopts sealing thread to be connected with cover 9.To the strong brine of 45% volume of packing in floating drum 1, floating drum 1 is vertically put into to the ammonium molybdate solution of container 7, make 1/2 of floating drum 1 highly immerse solution.Described connecting line 2 is nylon wire, and an end is fixed on the center of the upper cover 9 of floating drum 1, walks around two pulleys 4, and the other end connects isosceles triangle indicator dog 5, and the weight of adjusting isosceles triangle indicator dog 5 makes it with the floating drum 1 that is positioned at solution by the connecting line balance.According to the initial liquid level of measuring, isosceles triangle indicator dog 5 over against the storage tank side for fluorescent pigment draw the liquid level scale mark, in order to also can read liquid level evening.
When the liquid level in container 7 changes, floating drum 1 will vertically move along with liquid level changes up and down, and the isosceles triangle indicator dog 5 be attached thereto also moves synchronous backward, sensitive liquid level of clearly indicating in container 7.When the larger solution of this another specific gravity difference of container splendid attire, as long as floating drum 1 is taken out, to adjust the liquid amount in floating drum 1 or adjust dress liquor ratio weight, floating drum 1 will be again in correct position and indicator dog balance, and this level instruction device is still sensitive available.
