The beneficial effects of the utility model are that: the utility model discloses can in time monitor the pressure of intermediate frequency furnace circulating water to the rapid alarm signal that sends makes the counter -measure of making that the staff can be timely, and great reduction staff's intensity of labour has stopped the potential safety hazard of equipment.
Description
Technical field
The utility model belongs to electrolytic aluminium apparatus field, specifically a kind of intermediate frequency furnace circulating water pressure warning device.
Background technology
The operating frequency of intermediate frequency furnace, between 50～1000Hz, is widely used in the melting of non-ferrous metal and ferrous metal. Compare with Castingother equipment, intermediate frequency furnace has the advantage such as temperature and composition that the thermal efficiency is high, smelting time is short, alloying element scaling loss is few, melting material is wide, environmental pollution is little, can accurately control molten metal.
In intermediate frequency furnace, the element of electric furnace coil, yoke, water-cooled cable and the large electric current of power cabinet equivalent-load all needs water-cooled, and cooling water system is the critical system in intermediate frequency furnace device, is that support equipment is normally worked, the important component part of safe operation. At present, for preventing the element over-temperature such as electric furnace coil, yoke, water-cooled cable and power cabinet, need to configure a large amount of cooling systems, the cooling water in more such cooling system, after being heated, causes body internal pressure to increase, and therefore, has potential safety hazard for this reason.
Summary of the invention
For above technical deficiency, the utility model provides a kind of intermediate frequency furnace circulating water pressure warning device, can monitor in time the pressure of intermediate frequency furnace recirculated water, protection device security.
The technical scheme that the utility model adopts is: intermediate frequency furnace circulating water pressure warning device, comprise by the pond connecting by pure water pipeline, water pump, power cabinet, the pure water circulating system and the cooling tower being connected by soft water pipeline of cable composition, water pump, the soft water circulatory system of electric furnace coil composition, described water pump by distributive pipe respectively with power cabinet, cable is connected, between water pump and distributive pipe, be provided with electro connecting pressure gauge, between described water pump and electric furnace coil, be provided with electro connecting pressure gauge, the leading-out terminal of electro connecting pressure gauge is connected with the input of controller by control cables, the control output end of described controller is connected with alarm by control cables.
Between described water pump and electro connecting pressure gauge, be provided with valve.
Described alarm is audible-visual annunciator.
The beneficial effects of the utility model are: the utility model can monitor the pressure of intermediate frequency furnace recirculated water in time, and send rapidly alarm signal, make staff can make timely counter-measure, reduce greatly staff's labour intensity, stopped the potential safety hazard of equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is described further below with reference to embodiment and accompanying drawing.
As shown in Figure 1, intermediate frequency furnace circulating water pressure warning device, comprise by the pond 11 connecting by pure water pipeline 10, water pump 3, power cabinet 9, the pure water circulating system that cable 8 forms and the cooling tower 2 being connected by soft water pipeline 6, water pump 3, the soft water circulatory system that electric furnace coil 7 forms, described water pump 3 by distributive pipe respectively with power cabinet 9, cable 8 is connected, between water pump 3 and distributive pipe, be provided with successively valve 4, electro connecting pressure gauge 5, between described water pump 3 and electric furnace coil 7, be provided with electro connecting pressure gauge, the leading-out terminal of electro connecting pressure gauge 5 is connected with the input of controller 1 by control cables, the control output end of described controller 1 is connected with audible-visual annunciator 12 by control cables.
Water in pond pumps through water pump, flows into respectively by the road power cabinet, cable is cooling so that it is carried out, and cooled water outlet is got back to pond through circulation line, continues circulation next time; Water in cooling tower enters heating cord circle to carry out cooling to it after water pump pumps, cooled water outlet is got back to cooling tower through circulation line, enter circulation next time, in this process, cooling water is not exposed in air, avoided evaporation, thereby further avoided moisturizing, and cooling tower can carry out effective temperature-reducing to circulating backwater, thereby ensure the water temperature that enters electric furnace coil, avoided the scaling loss of coil.
Principle of the present utility model is: on intermediate frequency furnace water return pipeline, connect electro connecting pressure gauge, by the pressure in induction pipeline, as while exceeding setting pressure, it can provide the signal of telecommunication to controller, controller is connected audible-visual annunciator (also can adopt other warning devices such as digital alarm device) and is sent alarm signal, makes staff can make timely counter-measure.
