Description
Technical field
The invention belongs to lost foam casting industry technology field, particularly relate to the pinwheel cooler that a kind of sand temperature is controlled automatically.
Background technology
Existing cylinder generally adopts belt pulley transmission, and the time easily occurs skidding during trickle outside long or cylinder, and the speed of service obviously declines.In addition, existing cylinder adopts outside trickle to carry out cooling reduction sand temperature, if but client's output when larger, when sand temperature is higher, the existing type of cooling cannot make cast reach temperature required, causes Bai Mo to scald, and cannot normally produce.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned the deficiencies in the prior art exactly, and provide a kind of reliable transmission steady, avoid occurring skidding, and effectively control sand export temperature, improve the automatic pinwheel cooler of controlling of sand temperature of the sand treating capacity of equipment in the unit interval.
For solving the problems of the technologies described above, technical scheme of the present invention is:
The pinwheel cooler that a kind of sand temperature is controlled automatically, comprise cylinder, roller cover and drum drive, in cylinder edges at two ends, place is provided with gear wheel, at cylinder two ends, be respectively equipped with sand inlet and sand export, between cylinder outside and roller cover, be provided with spray equipment, also comprise the automatic atomising cooling device that is arranged on cylinder inside, in cylinder sand export one end, be provided with fan interface, this automatic atomising device comprises atomization pipeline, atomization pipeline one end extend into cylinder inside through sand inlet, its end is equipped with atomizer, the atomization pipeline other end connects cooling water source, on atomization pipeline, along water (flow) direction, booster pump is installed successively, strainer valve, electromagnetic flowmeter and magnetic valve, this automatic atomising device also comprises digital readout temperature controller and PLC controller, wherein electromagnetic flowmeter and magnetic valve are all electrically connected to PLC controller, described drum drive comprises transmission mechanism and actuating unit, pin chain link and duplex chain wheel that wherein transmission mechanism contains pair of meshing transmission, the rotating shaft both sides of duplex chain wheel are rotatably supported on bearing and bearing block.
Described actuating unit comprises motor and reductor.
Rotating shaft one end of described duplex chain wheel is direct-connected by shaft coupling and reductor.
Described spray equipment comprises the shower being fixed on roller cover inwall, along shower surface, towards cylinder side, is provided with at least one row's spray apertures.
The beneficial effect of technical solution of the present invention is:
1, structurally, the pinwheel cooler that sand temperature of the present invention is controlled has automatically changed the kind of drive of existing cylinder, according to the principle of pinwheel engagement and sprocket engagement, employing changes roller chain drum into pinwheel and sprocket engagement, structurally pinwheel has been inherited most of characteristic of chain, also the theory of engagement simultaneously that meet pinwheel, equipment change is that pinwheel transmission has overcome the skidding that former rubber tire produces by frictional drive, also reduced the frictional force of transmission, with rubber tire transmission rotation per hour, 420 enclosed in the past simultaneously, change into after pinwheel transmission, engagement steadily, there is no skidding, rotation 600 per hour, power has nearly increased by 1/3, simultaneously easy to maintenance, if a certain roller has been broken, can directly change, if this transmission is gear drive, if any a tooth, broken, must change whole gear, maintenance cost is too high.
2, structurally, the present invention, on the water-cooled basis of the outside pouring of cylinder, has increased automatic atomising cooling device in cylinder inside; Adopt the cooling mode combining in cylinder inside and outside, when client's output is larger, when sand temperature is higher, this type of cooling can make cast reach temperature required, avoids causing Bai Mo to scald, thereby guarantees normal production.Wherein, automatic atomising cooling device is to add atomized water in cylinder inside, different according to the height of each monitoring point sand temperature, controls electromagnetic flowmeter control and add the different atomized waters of inbound traffics with magnetic valve by PLC.When sand temperature is far above 100 degrees Celsius time, direct gasification, part sand can contain a certain amount of moisture, the steam of high temperature is taken away a part of heat, by blower fan, enter deduster, thereby reach cooling effect, due to simultaneously cooling inside and outside cylinder, sand temperature will control to rational temperature at sand export, thereby improve the sand treating capacity of equipment in the unit interval.Before not increasing this equipment, the temperature of shaking out, 65 ° of left and right, causes tunica albuginea to scald, and production line cannot be produced, and each on-the-spot increasing after this equipment, sand temperature is controlled at below 50 ° at sand export now, can meet client completely and manufacture demand.
3, to sum up, the pinwheel Refrigerator structure that sand temperature of the present invention is controlled is automatically reasonable in design, reliable transmission is steady, avoids occurring skidding, easy to maintenance, cost is low, and, can effectively control sand export temperature, improve the sand treating capacity of equipment in the unit interval, meet client and manufacture demand, therefore, be very suitable for promotion and implementation.
