Description
Technical field
The utility model relates to the equipment that abrasion-proof steel ball is carried out ageing treatment, especially a kind of high-efficiency abrasion-proof steel ball aging oven.
Background technology
At present, traditional abrasion-proof steel ball has body of heater with the timeliness stove and accessory, and below, body of heater inside is provided with a conveyor chain, and some circulation drainage blower fans of arranging over against conveyor chain are equipped with at the body of heater top, and burner and thermopair are housed respectively on the sidewall of the furnace body.The circulating air of the aging oven inside of this traditional structure all is to be directly injected to above the product or directly by recirculation blower hot blast is transported in the stove, and non-uniform temperature causes unstable product quality in the body of heater thereby directly the circulating air injection can be caused by recirculation blower like this.In addition, because the abrasion-proof steel ball tempering is low-temperaturetempering, main heat transfer type is transmission of heat by convection during low temperature, and rate of heat transfer is low-down during natural convection heat transfer, so, directly hot blast is transported to and can makes the time of ageing treatment oversize in the stove.Therefore, a kind of a kind of high-efficiency abrasion-proof steel ball aging oven that can address the above problem well of design extremely is necessary.
Summary of the invention
The purpose of this utility model is exactly the problem such as will solve that traditional abrasion-proof steel ball is large with aging oven hot blast consumption, the hot blast utilization ratio is lower, non-uniform temperature in the stove, steel ball ageing treatment time quality product long and that produce are undesirable, and a kind of high-efficiency abrasion-proof steel ball aging oven is provided.
Concrete scheme of the present utility model is: improve with aging oven for traditional abrasion-proof steel ball, it has body of heater, below, body of heater inside is provided with a conveyor chain, some circulation drainage blower fans of arranging over against conveyor chain are equipped with at the body of heater top, burner and thermopair are housed respectively on the sidewall of the furnace body, it is characterized in that: erecting frame all is equipped with in described circulation drainage blower fan bottom, the hot air circulation sparger all is equipped with in the erecting frame bottom, this hot air circulation sparger includes fan housing, the fan housing top is provided with blast inlet, the shockproof joint of arc is equipped with at the blast inlet place, and the shockproof joint welded top of arc has flange; Back up pad before and after being equipped with on the front and back sidewall of fan housing bottom is equipped with the angle bar that some spaced and parallel are arranged between the back up pad of front and back, form in twos trapezoidal air outlet wide at the top and narrow at the bottom between the angle bar.
Steel ball fixed bit described in the utility model on trapezoidal air outlet and the conveyor chain is over against layout.
The front and back side bottom of fan housing described in the utility model is provided with downward extension board.
The utility model is simple in structure, and is easy to use, and hot blast is evenly distributed in the body of heater, and the hot blast utilization ratio is higher, can carry out ageing treatment to steel ball quickly, has greatly improved the quality of productivity and product, has brought huge economic benefit to enterprise.

Among the figure: 1-circulation drainage blower fan, 2-erecting frame, 3-hot air circulation sparger, 4-conveyor chain, 5-body of heater, the 6-thermopair, 7-burner, 8-flange, 9-blast inlet, the shockproof joint of 10-arc, the 11-fan housing, the trapezoidal air port of 12-, 13-angle bar, 14-back up pad, 15-extension board.
Embodiment
Referring to Fig. 1 and Fig. 2, the utlity model has body of heater 5, body of heater 5 inner belows are provided with a conveyor chain 4, three circulation drainage blower fans 1 of arranging over against conveyor chain 4 are equipped with at body of heater 5 tops, burner 7 and thermopair 6 are housed respectively on body of heater 5 sidewalls, particularly: erecting frame 2 all is equipped with in described circulation drainage blower fan 1 bottom, and hot air circulation sparger 3 all is equipped with in erecting frame 2 bottoms.Referring to Fig. 3, Fig. 4, Fig. 5 and Fig. 6, this hot air circulation sparger 3 includes fan housing 11, and fan housing 11 tops are provided with blast inlet 9, and the shockproof joint 10 of arc is equipped with at blast inlet 9 places, and shockproof joint 10 welded top of arc have flange 8; Back up pad 14 before and after being equipped with on the front and back sidewall of fan housing 11 bottoms is equipped with the angle bar 13 that 16 spaced and parallel are arranged between the front and back back up pad 14, form in twos trapezoidal air outlet 12 wide at the top and narrow at the bottom between the angle bar 13.
