Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1-6, an arc furnace spout for improving appearance quality of electric melting AZS comprises a discharge channel 1, wherein a vertical discharge chute 2 is arranged at a discharge end of the discharge channel 1, when high-temperature feed liquid flows out of the discharge channel 1, the feed liquid is prevented from forming an arc line when flowing out and then impacting on the inner wall of a die, the feed liquid is further cooled on the inner surface of the die to form a layer of cold shell, cooling tanks 4 are arranged in the discharge channel 1 and the vertical discharge chute 2, a blocking component 3 is arranged in the discharge channel 1, and the cooling tank is used for preventing floating on the high-temperature feed liquid from flowing into the vertical discharge chute 2.
The inner walls of the discharging channel 1 and the vertical discharging groove 2 are smooth; the feed liquid is prevented from condensing on the inner walls of the discharge channel 1 and the vertical discharge chute 2.
The blocking assembly 3 comprises a clamping plate 31, inserting blocks 32 are fixedly arranged on two sides of the bottom of the clamping plate 31, inserting grooves 33 are formed in two side walls of the discharging channel 1, the two inserting blocks 32 can be respectively inserted into the two inserting grooves 33, a baffle 34 is fixedly arranged at the bottom of the clamping plate 31, a containing groove 35 is formed in the baffle 34, the containing groove 35 extends along one side of the baffle 34 to the other side, an arc-shaped vertical section of the containing groove 35 is arranged, and an arc-shaped opening is obliquely upwards.
When the electric arc furnace melts the feed liquid, the unavoidable some slag that has will not melt completely and float on the feed liquid top surface, blocks the slag through setting up baffle 34, sets up holding tank 35, stores in the arc bottom of holding tank 35 as the material flow direction.
Through setting up cooling tank 4, when feed liquid is added to the mould to ejection of compact way 1 and vertical blown down tank 2, pour into cooling water and cool off ejection of compact way 1 and vertical blown down tank 2 in order to lengthen life into cooling tank 4.
In the first embodiment of the utility model, the vertical discharge chute 2 has a vertical chute-like structure, and the discharge chute 1 and the vertical discharge chute 2 are integrally formed, that is, are fixedly connected together.
When the feed liquid in the discharge channel 1 flows out, the feed liquid directly flows into the vertical discharge chute 2, and under the guidance of the vertical discharge chute 2, the direction of feed liquid outflow is close to vertical downward, so that the feed liquid can face the bottom of the die when flowing out, the phenomenon that the product interlayer phenomenon can be directly reduced when the material flows down along the inner wall of the die and then the brick in the die is formed is avoided when the material flows out.
In order to avoid that the vertical discharge chute 2 is driven to rotate when the arc furnace rotates by a large angle, the vertical discharge chute 2 is caused to deviate from a vertical downward angle too much.
In the second embodiment of the present utility model, unlike the first embodiment, the vertical discharge chute 2 has a vertical cylindrical structure, and the discharge chute 1 is rotatably connected to the vertical discharge chute 2, and the center of gravity of the vertical discharge chute 2 is near the bottom thereof, that is, the center of gravity of the vertical discharge chute 2 is far from the rotation axis of the vertical discharge chute 2.
When the material in the material outlet channel 1 flows into the vertical material outlet channel 2, the material liquid flowing downwards from the material outlet channel 1 impacts the vertical material outlet channel 2, at the moment, the impact point and the rotating shaft are basically on the same horizontal plane, the gravity center of the vertical material outlet channel 2 is far, the vertical material outlet channel 2 cannot deflect at a large angle, in the specific implementation process, only a certain slight deflection can occur, and the deflection process cannot influence the material liquid in the vertical material outlet channel 2 to directly flow to the bottom of the die.
In this embodiment, the two sides of the discharging channel 1 are provided with rotating grooves, the two sides of the vertical discharging channel 2 are fixedly provided with rotating shafts, and the rotating shafts are rotatably arranged in the rotating grooves and are in clearance fit with the rotating grooves.
When feed liquid flows to the discharge channel 1 and the vertical discharge chute 2, the high temperature of the feed liquid causes the expansion of the materials of the discharge channel 1 and the vertical discharge chute 2, so that the rotating shaft is not clamped in the rotating sleeve, and when the discharge channel 1 rotates for a certain angle along with an electric arc furnace, the vertical discharge chute 2 can still keep a vertical downward state.
Preferably, the bottom of the vertical discharging chute 2 is of a funnel-shaped structure, and when the feed liquid flows out from the bottom of the vertical discharging chute 2, the outflow hole is smaller, and the feed liquid flows into the bottom of the die more accurately.
The specific working principle is as follows: when pouring the feed liquid in the electric arc furnace into the mould, can make the feed liquid can directly dash in the bottom of mould when flowing to the mould through setting up vertical blown down tank 2, can not appear striking the condition of mould medial plate, very big all reduce the intermediate layer emergence rate on product surface, through rotating vertical blown down tank 2 that sets up on discharge channel 1, even the electric arc furnace is inclined certain angle also can make vertical blown down tank 2 keep vertical state when pouring the feed liquid, blocks the slag that does not melt in the feed liquid through setting up the baffle, improves the finished product effect of product.
