Description

Technical Field

[0001] The utility model relates to the field of metal smelting, in particular to a spraying device for metal smelting. Background Technique

[0002] Metal smelting is to remove the impurities of metals in minerals through high temperature. When smelting metals, due to the high temperature, the natural cooling speed is slow, the cooling time is long, and the smelting efficiency is low. Therefore, a spraying device needs to be used to spray the coolant on the metal surface so that the metal can cool at an appropriate speed. However, when the current spraying device sprays the coolant, most of the nozzles are fixed and can only spray a part of the metal. It is difficult to spray the coolant on the sides and bottom of the metal, resulting in uneven cooling of the metal, which makes the metal prone to fracture, deformation and crack tendency, thereby affecting the quality of the final product. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a spraying device for metal smelting, which can increase the spraying angle and range, make the metal cool evenly, and improve the product quality.

[0004] The technical solution of the utility model is as follows: A spraying device for metal smelting includes a chassis, a rotary joint, a water inlet pipe, a shower head, a motor, a driving gear, a column gear, a mounting frame, a nozzle, a return spring, a branch pipe and a hose. The middle of the inner top of the chassis is fixedly connected with a rotary joint. The lower end of the rotary joint is fixedly connected with a water inlet pipe. The water inlet pipe is communicated with the rotary joint. The upper end of the rotary joint is rotatably connected with a shower head. There are several protrusions on the top of the shower head. The shower head is communicated with the rotary joint. The inner side of the chassis is fixedly connected with a motor. A driving gear is arranged on the output shaft of the motor. A column gear is fixedly connected to the lower part of the shower head. The column gear meshes with the driving gear. The upper part of the chassis is fixedly connected with a mounting frame. Two nozzles are slidably connected to the upper part of the mounting frame. Return springs are arranged between the two nozzles and the mounting frame. The two nozzles are both directly above the shower head. A branch pipe is fixedly connected to the side of the water inlet pipe away from the rotary joint. The water inlet pipe is communicated with the branch pipe. Two hoses are fixedly connected to the top of the branch pipe. The two hoses are respectively communicated with the two nozzles and fixedly connected to the two nozzles. The two hoses are respectively communicated with the two nozzles.

[0005] As a preferred technical solution of the utility model, it further includes a bidirectional lead screw, a bidirectional nut, a connecting frame and an arc pushing frame. The output shaft of the motor is fixedly connected with a bidirectional lead screw. The bidirectional lead screw is rotatably connected with the mounting frame. The upper part of the bidirectional lead screw is threadedly connected with a bidirectional nut. The bidirectional nut is fixedly connected with a connecting frame. The output shaft of the motor is fixedly connected with a connecting frame. The lower part of the connecting frame is slidably connected to the side of the mounting frame close to the bidirectional lead screw. The arc pushing frame is fixedly connected to the upper part of the connecting frame. The arc pushing frame contacts the tops of the two nozzles. The upper end of the branch pipe and the lower parts of the two hoses both pass through the arc pushing frame.

[0006] Advantages of the utility model: The output shaft of the motor drives the driving gear to rotate, the driving gear drives the meshing column gear to rotate, the column gear drives the shower head to rotate, the shower head drives the metal to rotate, and then the shower head sprays out the coolant, thereby spraying the bottom of the metal to reduce the temperature of the bottom of the metal. The coolant flowing into the branch pipe will flow into the two nozzles, and the coolant is sprayed out from the lower outlets of the two nozzles to spray the upper surface of the metal, so that the upper surface of the metal is cooled. Further cooling the upper surface of the metal improves the metal cooling speed.

[0007] The driving gear drives the bidirectional lead screw to rotate, causing the bidirectional nut to move up and down reciprocally. The bidirectional nut moving up and down reciprocally drives the connecting frame to move up and down reciprocally, and the connecting frame moving up and down reciprocally drives the arc-shaped pusher to move up and down reciprocally. As a result, the arc-shaped pusher contacts the two nozzles and drives the two nozzles to swing left and right reciprocally. The two nozzles spray the side surface of the rotating metal, increasing the angle and range of the coolant spray, enabling the coolant to spray the metal surface more comprehensively, and further making the metal cooling uniform, reducing the possibility of the metal breaking or deforming, and improving the product quality.

Specific implementation manners

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0015] Embodiment 1: A spraying device for metal smelting, as Figures 1 - 5 shown, comprising a chassis 1, a rotary joint 2, a water inlet pipe 3, a shower head 4, a motor 5, a driving gear 6, a column gear 7, a mounting bracket 8, a nozzle 9, a return spring 10, a branch pipe 11 and a hose 12. The middle of the inner top of the chassis 1 is connected to the rotary joint 2 by rivets. The lower end of the rotary joint 2 is connected to the water inlet pipe 3 by bolts. The water inlet pipe 3 is used to introduce coolant, and the water inlet pipe 3 is communicated with the rotary joint 2. The upper end of the rotary joint 2 is rotatably connected to the shower head 4. The top of the shower head 4 is provided with a number of protrusions. The small protrusions lift the metal, reducing the contact area between the bottom of the metal and the shower head 4, so that the coolant is sprayed onto the bottom of the metal. The shower head 4 is communicated with the rotary joint 2. The inner side of the chassis 1 is connected to the motor 5 by bolts. A driving gear 6 is provided on the output shaft of the motor 5. A column gear 7 is connected to the lower part of the shower head 4 by bolts. The column gear 7 meshes with the driving gear 6. The driving gear 6 drives the column gear 7 and the shower head 4 to rotate. The upper part of the chassis 1 is welded with a mounting bracket 8. Two nozzles 9 are slidably connected to the upper part of the mounting bracket 8. Return springs 10 are provided between the two nozzles 9 and the mounting bracket 8. The two nozzles 9 are both located directly above the shower head 4. One side of the water inlet pipe 3 away from the rotary joint 2 is connected to the branch pipe 11 by a flange. The water inlet pipe 3 is communicated with the branch pipe 11. The coolant flows into the branch pipe 11 through the water inlet pipe 3. Two hoses 12 are connected to the top of the branch pipe 11 by flanges. The two hoses 12 are respectively communicated with the two nozzles 9. The coolant flows into the two nozzles 9 through the two hoses 12 and then sprays out from the lower outlets of the two nozzles 9. The two hoses 12 are connected to the two nozzles 9 by flanges, and the two hoses 12 are respectively communicated with the two nozzles 9.

[0016] When the utility model is in use, first, the operator places the metal on the shower head 4, starts the motor 5 and passes the coolant into the water inlet pipe 3. The motor 5 drives the driving gear 6 to rotate through the output shaft. The rotation of the driving gear 6 drives the engaged column gear 7 to rotate. The rotation of the column gear 7 drives the shower head 4 to rotate, so that the metal on the shower head 4 rotates. The coolant will flow into the water inlet pipe 3 and the branch pipe 11. The coolant flowing into the water inlet pipe 3 will flow into the shower head 4 through the rotary joint 2. Then the shower head 4 sprays out the coolant, thereby spraying the bottom of the metal to reduce the temperature of the bottom of the metal. The coolant flowing into the branch pipe 11 flows through the two hoses 12, and then flows into the two spray heads 9 through the two hoses 12. The coolant sprays out from the lower outlets of the two spray heads 9 to spray the upper surface of the metal, so that the temperature of the upper surface of the metal is reduced, further cooling the metal and increasing the metal cooling speed.

[0017] Embodiment 2: On the basis of Embodiment 1, as Figure 2 shown, it further includes a bidirectional lead screw 13, a bidirectional nut 14, a connecting frame 15 and an arc pushing frame 16. The output shaft of the motor 5 is bolted with a bidirectional lead screw 13. The bidirectional lead screw 13 is rotatably connected to the mounting frame 8. The upper part of the bidirectional lead screw 13 is threadedly connected with a bidirectional nut 14. The bidirectional nut 14 is welded with a connecting frame 15. The output shaft of the motor 5 is bolted with a connecting frame 15. The lower part of the connecting frame 15 is slidably connected to one side of the mounting frame 8 close to the bidirectional lead screw 13. The arc pushing frame 16 is connected to the upper part of the connecting frame 15 by rivets. The arc pushing frame 16 contacts the tops of the two spray heads 9, so that the two spray heads 9 swing reciprocally. The upper end of the branch pipe 11 and the lower parts of the two hoses 12 both pass through the arc pushing frame 16.

[0018] The motor 5 drives the bidirectional lead screw 13 to rotate through the output shaft, so that the bidirectional lead screw 13 drives the bidirectional nut 14 to move up and down reciprocally. The up and down reciprocal movement of the bidirectional nut 14 drives the connecting frame 15 to move up and down reciprocally. The up and down reciprocal movement of the connecting frame 15 drives the arc pushing frame 16 to move up and down reciprocally, so that the arc pushing frame 16 contacts the two spray heads 9. When the arc pushing frame 16 moves downward, the arc pushing frame 16 pushes the left spray head 9 to move to the left and the right spray head 9 to move to the right, and the return spring 10 is stretched, thereby spraying the side surface of the rotating metal, increasing the spraying angle and range of the coolant, making the coolant spray the metal surface more comprehensively, and thus making the metal cooling uniform, reducing the possibility of fracture inside the metal, improving the product quality. When the arc pushing frame 16 moves upward, the return spring 10 resets and drives the two spray heads 9 to reset, spraying and cooling the upper surface of the rotating metal, further increasing the metal cooling speed. Repeating this way, the metal can be continuously sprayed and cooled. After the cooling is completed, the operator turns off the motor 5 and stops passing the coolant into the water inlet pipe 3.
