The utility model is at a large amount of steam of granulating pit, and naked eyes cannot be seen under the adverse circumstances of granulating pit water level, by water level acoustooptic alarm system, make post operation personnel, grasp in time water level situation, regulates water level height, guarantees the normal use of blast furnace slag quenching water.
As shown in Figure 3:
Described sound and light alarm part 3 is established audible-visual annunciator 10, and described contact 9 is connected with audible-visual annunciator 10 by circuit.
Described sound and light alarm part 3 is established and is triggered sheet slideway 8, in the middle of described triggering sheet slideway 8, establishes vertical chute, and described triggering sheet 6, in this chute, is slidably matched with its formation; Described contact 9 is located at the bottom of described chute.
The other end of ball float running part 2 moves up and down along chute for triggering sheet 6, and is connected to audible-visual annunciator 10.
Described contact 9 adopts being fixedly connected with of adjustable upper-lower position with being connected of chute.
Contact 9 height of audible-visual annunciator are adjustable, can meet different water level control requirements,
Contact can freely be adjusted on slideway, can be according to technological requirement, and simple and effective adjustment water-level alarm value, makes the convenient control water level of post operation personnel, meets the requirement of blast furnace industrial water.
Described triggering sheet slideway 8 is provided with the scale that shows to trigger sheet 6 height and positions.Consider ensuring smooth transmission, trigger sheet slideway 8 and indicate scale, the contact 9 of audible-visual annunciator can freely be adjusted flexibly along the high and low position that triggers sheet slideway 8, then fixing.Can effectively learn the concrete height value of granulating pit 1 water level, can, according to technological requirement, adjust simply and effectively water-level alarm value again.
The triggering sheet slideway 8 of ball float running part 2 indicates scale, can directly read slag bath 1 water level, can, intuitively according to the particular location that triggers sheet, effectively learn the concrete height value of water level, easy to operate, adjusts simply, uses reliable.
By this system, the water level of granulating pit 1 is directly embodied on slideway scale intuitively, and according to the requirement of granulating pit 1 situation, water level management, adjust at any time the restriction of reporting to the police, greatly facilitate the water level management and supervision of post operation personnel to granulating pit 1.
Described ball float 4 adopts empty oil drum to make, and grain slag is equipped with in inside, and its weight is adjustable, mode be by place at empty oil drum grain slag amount number regulate.
Ball float 4 is for making of empty oil drum voluntarily, and grain slag is equipped with in inside, can, according to the different weight of adjusting of flushing cinder water density, guarantee that ball float 4 swims on the water surface, and have again certain weight, drives the triggering sheet 6 of the other end to move up and down.Guarantee that ball float 4 swims on the water surface, and have again certain weight, drive the triggering sheet of the other end to move up and down.
Become movable and fixed pulley 5 slip drag sizes according to the interior buoyancy of water of granulating pit 1, can adjust at any time, can guarantee to float on the water surface, there is again certain weight, drive the triggering sheet 6 of the other end to move up and down, effectively perception fluctuation of water table, efficiently solves general ball float weight inadequate, fixed pulley slip change in resistance, cannot drive the problem that sheet 6 moves that triggers.
The course of work of the present utility model is such:
Ball float running part 2 adopts fixed pulley 5 transmissions, and ball float 4 has certain weight, floats on granulating pit 1 surface, can fluctuate along with the height of liquid level water level.
In the time that liquid level in granulating pit 1 raises, ball float 4 rises, and shackle line 7 slides along fixed pulley 5, and the triggering sheet 6 that makes the other end is along triggering sheet slideway 8 down slidings, and in the time touching contact 9, audible-visual annunciator 10 connects and conducts, and glistens and reports to the police;
In the time that liquid level in granulating pit 1 reduces, ball float 4 declines, and triggering sheet 6 is being pulled and is moving upward, and leaves contact 9, audible-visual annunciator 10 stop alarms;
In the time that water level is basicly stable, contact 9 is generally positioned at triggers sheet slideway 8 bottoms, at this moment triggers sheet 6 at the scale that triggers stop place on sheet slideway 8, is water level height.
As because of technological requirement, water-level alarm point needs to promote, select contact 9 is moved up along triggering sheet slideway 8, at this moment trigger sheet 6 at the scale that is triggering stop place on sheet slideway 8, deduct contact 9 at the scale that triggers stop place on sheet slideway 8, be the water level height numerical value of granulating pit 1, analyze judgement for operating personnel.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
