AI Technical Summary
In the existing blowing device, when the material is added, the spray gun easily collides with the material, resulting in a loss of stability and the easy escape of smoke.
A device including a furnace body, a slide plate, a cylinder, and a spray gun was designed. The slide plate moves the spray gun away when the material is fed, increasing the distance between the material and the spray gun, and the slide plate also closes the feed hopper to ensure the safety of the spray gun. At the same time, a crushing box and a guide chute are set to control the size of the material and the emission of flue gas.
This effectively prevents material from damaging the spray gun, improves the blowing efficiency, and purifies the flue gas through negative pressure pipelines, ensuring the stable operation of the unit.

DETAILED DESCRIPTION
[0017] The utility model discloses the beneficial effect is:
[0018] As Figures 1-4 The utility model discloses a blowing device for copper matte smelting, including furnace body 1, the inside of furnace body 1 is provided with furnace lining 2, furnace lining 2 is made of refractory material, one side of furnace body 1 is provided with the material taking port, and the material taking port is provided with door plate 3, and the upper end of furnace body 1 is provided with feeding port and smoke outlet 6, and the upper end of feeding port is provided with feeding hopper 7, and the lower end of feeding hopper 7 is provided with sliding slot, and the inside of sliding slot is provided with sliding plate 4, and sliding plate 4 is provided with air cylinder 5, and the output end of air cylinder 5 is fixedly connected with smoke outlet 6, and sliding plate 4 is provided with lance 8, and the upper end of furnace body 1 is provided with through slot 9 for the movement of lance 8, and sliding plate 4 always covers the through slot 9 on furnace body 1.
[0019] When the material is put into the furnace body 1, first, the material to be put is placed into the feeding hopper 7, when the material is put into the feeding hopper 7, the air cylinder 5 is started, the output end of the air cylinder 5 is retracted, the air cylinder 5 drives the sliding plate 4 to move towards the smoke outlet 6, when the sliding plate 4 moves, the lower end of the feeding hopper 7 is communicated with the inside of the furnace body 1, the material in the feeding hopper 7 falls into the furnace body 1, when the sliding plate 4 moves, the lance 8 is driven to move in the through slot 9, so that the distance between the lance 8 and the falling material is increased, so that the falling material does not damage the lance 8, when the material is put into the furnace body 1, the output end of the air cylinder 5 is extended, the sliding plate 4 is reconnected with the feeding hopper 7 and the furnace body 1, so that the lance 8 can be moved to the center of the furnace body 1, at the same time, the flue gas can be discharged from the smoke outlet 6, so that the flue gas is difficult to escape from the feeding hopper 7.
[0020] Further, the upper end of the feeding hopper 7 is provided with a crushing box 10, the inside of the crushing box 10 is provided with two crushing rollers 11 which are engaged with each other, the two crushing rollers 11 are driven by the gear 12, the outside of the crushing box 10 is provided with a speed reducer motor 13 for driving one of the crushing rollers 11 to rotate, the inside of the crushing box 10 is symmetrically provided with two baffles 14 below the crushing rollers 11, the baffles 14 are rotatably connected with the crushing box 10, the torsional spring 15 is arranged between the crushing box 10 and the baffles 14, the two ends of the baffle 14 are provided with the swing rod 16, the swing rod 16 is located outside the crushing box 10, the outer surface of the crushing box 10 is provided with the limiting rod 17, when the material is put, the size of the material is reduced, so that the blowing efficiency is improved, specifically, the material is put into the crushing box 10, after the material is crushed by the crushing rollers 11, the material falls on the baffles 14, under the action of the gravity of the material, the torsional spring 15 is rotated, so that the baffle 14 is rotated, so that most of the crushed material can enter the feeding hopper 7, finally, the residual material on the baffle 14 is not enough to make the torsional spring 15 overturn, at the same time, the torsional spring 15 pushes the baffle 14 upwards by the elastic force, until the swing rod 16 contacts with the limiting rod 17, the two baffles 14 keep horizontal state, the two baffles 14 are used to separate the crushing box 10 and the feeding hopper 7, so that when the crushed material in the feeding hopper 7 is put into the furnace body 1, the flue gas is difficult to escape from the crushing box 10 to the outside, so that most of the flue gas is still discharged through the smoke outlet 6.
