Description

Quench hot fuel tank refrigerating unit

Technical field

The utility model relates to a kind of quench hot fuel tank refrigerating unit, particularly has the quench hot fuel tank refrigerating unit of the type of cooling.The quenching heat treatment apparatus field that belongs to each big-and-middle-sized die part and various mechanical workout metallic substance spares.

Background technology

In recent years steel alloy day quenching amount significantly increases, heating is come out of the stove about four to ten hours of pitch time, at present: the quenching fuel tank of (1) no refrigerating function is that the angle steel by five steel plates and four upper frames is welded into, oil in the case bears the quenching part once more in the short at interval time heating, the very fast oil of continuous increase with the quenching part reaches burning-point and on fire often, and warning rectification notice is repeatedly assigned by peace skill department;

(2), repeat again after the temper again to heat and quench and incur loss through delay and finish the manufacturing node because of oily Wen Taigao quenching part hardness does not reach requirement;

(3) have no alternative but adopt carbon steel quenching fuel tank to handle in the higher position very much because of oily temperature,, have few moisture in the fuel tank surface cracking of incomplete quench spare is scrapped because of oily medium behind the carbon steel elder generation water quenches;

(4) hang basket in the case and adopt thin steel plate and shaped steel to be welded into and intensity is very poor, fill the quenching part and hang basket and fall to being put in the two piece steel pipes of frame at fuel tank, the press-bending steel pipe is with to hang the basket badly broken very dangerous in the use;

(5) the underground fuel tank of reparation damage, oil pump, water pump, cooling tower, two-way Fourth Ring pipeline, quenching fuel tank etc. will drop into than big fund and manpower and just can satisfy existing production demand.

Described quench hot fuel tank refrigerating unit as carrier bar, vertically constitutes at the bottom of the fuel tank and the air communication channel between at the bottom of the fuel tank installation pond at 3～5 vertical worker's shaped steel of fuel tank bottom weldering between worker's shaped steel.

Described quench hot fuel tank refrigerating unit hangs to add under the basket framework and welds 3～5 hollow type girder steels; The telescopic safety supports mechanism that rises and falls is installed on the hollow type girder steel of both sides.

Described quench hot fuel tank refrigerating unit, the telescopic safety supports mechanism that rises and falls comprises the axle sleeve that is fixed on the box girder of both sides, and with the back shaft of axle sleeve coupling, axle sleeve is stretched out at the back shaft two ends, and there is the spacing head greater than axle sleeve at the back shaft two ends.

Described quench hot fuel tank refrigerating unit, fuel tank are installed the bottom, pond air-cooled blow gun and air-supply pipeline; Fuel tank is installed bottom surface, pond one side long-pending oil hole groove.

The beneficial effects of the utility model: this quench hot fuel tank refrigerating unit self has the heat radiation refrigerating function, and it is simple and direct, cheaper, very practical metal quenching facility.

The casing periphery is equipped with the speed that heat radiation is accelerated in circulation that radiator element and bottom be blown into air, thoroughly avoids high temperature oil hidden danger on fire, satisfies the demand of the productive temp of two stoves that day quench fully.Hanging basket adopts abundant material to be welded into high-intensity frame body, join the lifting of standard loop chain suspender, lifting by crane four jiaos of place's push-and-pull back shafts is placed on the horizontal frame of fuel tank safe and efficient, porous is leaked bleed, and lifting cartonning lifting is practical rapidly, and hanging has hollow section steel beam under the basket framework, make quenching part and bottom half form the space, can prevent of the damage of quench hot spare, be beneficial to cooling oil again and roll, equably the quenching part be quenched bottom half.
