The electrolyzer feed bin blanking weighing device of operating machine
Technical field:
The utility model relates to the feed bin blanking weighing device of electrolyzer usefulness operating machine in a kind of Aluminium Electrolysis.
Technical background:
Electrolyzer contains such function with operating machine: earlier from the factory building top with under the alumina material in its feed bin, again these material are progressively covered on the new anode by fixed amount during anode to be changed.In order to grasp what of aluminum oxide in the feed bin, a cover monitoring device must be set on feed bin.At present, the electrolyzer operating machine is that a cover blocking rotary type or a radio frequency admittance formula level gage directly respectively is installed on the bulkhead up and down of feed bin sidepiece.The limitation of these two kinds of blanking monitoring devices is: can only be to the material of feed bin full and empty 2 of material monitor; Can not adjust after installing, easily cause material dress discontented or overflow; On new anode, during mulch, can only can cause very big randomness, cause waste with operator's experience control blanking amount.Particularly the blocking rotary type level gage is owing to itself structure, often because of expecting full stall, fragile aborning.Therefore, existing blanking is weighed mode in use, and its effect is not ideal enough.
Summary of the invention:
The purpose of this utility model is: provide a kind of simple in structure, useful range is wide, the electrolyzer of reliable in action and may command input and output material amount is with the feed bin blanking weighing device of operating machine, to address the above problem.
The utility model is to constitute like this: it is made up of resting support (1), LOAD CELLS (3) and top board (4), passes bearing pin (5) between resting support (1) and the feed bin (6) and locatees with horizontal direction; LOAD CELLS (3) is installed on the resting support (1), and the detection termination vertical junction of the bottom of top board (4) and LOAD CELLS (3) is touched; Pull bar (2) passes top board (4), resting support (1) and feed bin (6), at the two ends of pull bar (2) nut (7) is housed.
Owing to adopted technique scheme, in use, output of each point LOAD CELLS and the corresponding current signal of suffered gravity size handle just to obtain the material amount that feed bin any time adorned through PLC, and transmit signals to telepilot and controlled.Therefore, the utility model compared with prior art has that useful range is wide, reliable in action, may command input and output material amount and an advantage of simple structure.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment:
Embodiments of the invention: as shown in Figure 1, bearing pin (5) is passed resting support (1) and feed bin (6) is located with horizontal direction, LOAD CELLS (3) is installed on the resting support (1), top board (4) is placed on the LOAD CELLS (3), make the bottom of top board (4) contact, and this point of contact is positioned at the center of gravity place of weighing system with the detection termination of LOAD CELLS (3); Then pull bar (2) is passed top board (4), resting support (1) and feed bin (6), and it is fixing with the nut (7) that is installed on pull bar (2) two ends, by adjusting nut (7), make perpendicular the getting final product of horizontal seat board of LOAD CELLS (3) and top board (4), resting support (1) and feed bin (6) simultaneously.So, the weight of material just can be passed through feed bin (6), pull bar (2), top board (4), form with power passes to LOAD CELLS (3), and the junction operated by rotary motion three of resting support (1) and feed bin (6) is overlapped these weighing systems when mounted, to support feed bin (6).
