Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail.
Refer to Fig. 1, the invention provides a kind of steel ball reheating furnace production line, comprising: feeding conveyor 10, reheating furnace 30 and outfeed belt conveyor 40; Reheating furnace 30 comprises furnace body support 31, and the table top relative level face tilt of furnace body support 31 is arranged, on the table top of furnace body support 31, be provided with body of heater 32, and body of heater 32 is the masonry adopting lagging material.Arrange heated chamber 33 in body of heater 32, steel ball opening for feed 34 is offered in one end (one end that relative level face height is higher) of heated chamber 33, and feeding conveyor 10 is connected with steel ball opening for feed 34; The other end of heated chamber 33 offers steel ball discharge port 35, and outfeed belt conveyor 40 is connected with steel ball discharge port 35; In heated chamber 33, many groups that is provided with at interval are elevated stop gauge 36, and heated chamber 33 is divided into several little heated chambers by the spaced lifting stop gauge 36 of many groups.
During the work of this steel ball reheating furnace production line, by feeding conveyor 10 automatically by Steel ball conveyor to steel ball opening for feed 34, the bottom surface that steel ball tilts along body of heater 32 rolls into heated chamber 33 automatically; By the order of steel ball discharge port 35 to steel ball opening for feed 34, each little heated chamber filled successively by steel ball, and after little heated chamber fills steel ball, lifting stop gauge 36 rises and forms interval.After steel ball completes heating, by the order of steel ball discharge port 35 to steel ball opening for feed 34, lifting stop gauge 36 reduces successively, and steel ball exports from steel ball discharge port 35, and by outfeed belt conveyor 40, steel ball is transported to subsequent processing.The level of automation of this steel ball reheating furnace production line is high, and all adopt automated operation from the charging of steel ball and discharging, production efficiency is high; And, in heated chamber 33, interval is provided with many group lifting stop gauges 36, heated chamber 33 is divided into several little heated chambers by spaced lifting stop gauge 36, heat-up time, the goal amount of the steel ball in each little heated chamber and go out ball amount and all can control, the heats of steel ball is good.
Refer to Fig. 2 and Fig. 3, lifting stop gauge 36 comprises the baffle plate 361 be arranged in heated chamber 33, and baffle plate 361 is connected with lifting drive member 362 through the base plate of body of heater 32, and lifting drive member 362 is fixed on furnace body support 31.In the process of baffle plate 361 rise and fall, for anti-baffle plate 361 swings, and there is stuck phenomenon, and strengthen the intensity of baffle plate 361, preferably, in heated chamber 33, the both sides of baffle plate 361 are respectively arranged with guiding guide wheel 37, guide effect is played in the rise and fall of guiding guide wheel 37 pairs of baffle plates 361, and can form the support to baffle plate 361.Baffle plate 361 when mounted, through the base plate of body of heater 32, when reheating furnace 30 works, will being full of high-temperature gas in heated chamber 33, for avoiding the outflow of high-temperature gas, avoiding thermal energy to lose; Preferably, in the bottom surface of body of heater 32, baffle plate 361 is provided with water sealed tank 38 with the combination section of body of heater 32 and seals.Preferably, be the sensitivity improving lifting stop gauge 36, can allow baffle plate 361 fast rise and fall, lifting drive member 362 is pneumatic cylinder.
Operationally, for preventing steel ball stuck, there is the phenomenon of not automatic rolling in reheating furnace 30.Preferably, setting gauge 39 is provided with between two groups of adjacent lifting stop gauges 36; Setting gauge 39 comprises material toggling block 391, and material toggling block 391 is connected with the material toggling cylinder 392 be arranged on body of heater 32 top board.When discharging, material toggling cylinder 392 drives material toggling block 391 swing can promote steel ball and rolls toward steel ball discharge port 35 place; Meanwhile, the residue in heated chamber 33 also can be cleaned out heated chamber 33 by material toggling block 391, keeps the clean of heated chamber 33.
Preferably, for convenience of the metering to steel ball goal amount, steel ball opening for feed 34 place is provided with feed charging meter batch box 20, and feeding conveyor 10 is connected with steel ball opening for feed 34 by feed charging meter batch box 20.When feeding conveyor 10 transporting steel balls, steel ball accumulates in feed charging meter batch box 20, and when reaching preset weight, feeding conveyor 10 stops feeding, and the steel ball in feed charging meter batch box 20 directly enters reheating furnace 30.Because the capacity of feed charging meter batch box 20 artificially can set according to processing request, therefore the goal amount of reheating furnace 30 can require according to different process and determine, more scientific and reasonable.
Preferably, steel ball discharge port 35 place is provided with discharging door 41, and discharging door 41 is connected with driving pneumatic cylinder 42.Discharging door 41 adopts and drives pneumatic cylinder 42 to control, and automatization is opened, and is easy to control.
Preferably, the angle of the table top relative level face tilt of furnace body support 31 is less than or equal to 8 °.The angle that the table top of furnace body support 31 tilts is excessive, and the pressure of steel ball to lifting stop gauge 36 is excessive, requires that lifting stop gauge 36 has higher intensity, is unfavorable for the design being elevated stop gauge 36.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
Level of automation is high, and all adopt automated operation from the charging of steel ball and discharging, production efficiency is high; The heat-up time, soaking time etc. of the steel ball in heated chamber 33, Discrete control can be realized, the goal amount of steel ball with go out ball amount can stability contorting, realize high-quality production.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention; For a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
