Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron and steel smelting technology, and in particular to a novel spray gun. Background Technology
[0002] The slag removal process after molten iron pretreatment involves tilting the molten iron ladle and using a slag remover to remove the slag floating on the surface of the molten iron. Due to the limitations of the shape of the molten iron ladle and the slag removal plate, the slag removal plate cannot extend to the rear wall of the molten iron ladle, making it difficult to remove the slag in that area. At the same time, because the slag on the surface of the molten iron is scattered and floating, the amount of slag removed in a single slag removal operation is small, resulting in a large number of slag removal operations, long slag removal time, low slag removal efficiency, large iron loss during slag removal, and high operating costs. This restricts the improvement of the technical and economic indicators of the pretreatment process and the realization of production benefits. Therefore, it is necessary to use a spray gun to gather the slag to achieve the slag agglomeration effect.
[0003] Chinese patent document CN103114177A discloses an air-blowing slag-gathering spray gun for assisting molten iron slag removal and its usage method. The air-blowing slag-gathering spray gun includes a barrel with an open end and a closed end. Near the closed end, nozzles are symmetrically arranged on the barrel wall with the barrel's central axis as the guide. The central axis of the nozzles is perpendicular to the central axis of the barrel, and the ratio of the nozzle's inner diameter to the barrel's inner diameter is 0.35 to 0.70:1. The air-blowing slag-gathering spray gun features a simple structure, long service life, and stable air-blowing slag removal operation. Combined with its usage method, this invention can improve the degree of molten iron slag aggregation, increase the exposed area of molten iron, reduce scouring and wear on the ladle wall, minimize slag removal iron loss, and shorten slag removal time.
[0004] The existing technology has the following problems:
[0005] The spray gun uses a single rotating part to rotate it, but in actual operation, due to the large area of the inner wall of the molten iron ladle and the relatively concentrated spray nozzle, the slag accumulation efficiency is low. Utility Model Content
[0006] This invention provides a novel spray gun to solve the problems mentioned in the background section.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0008] A novel spray gun includes a support frame, an adjustment mechanism slidably connected to the inner side of the support frame, a spray gun body rotatably connected to the inner side of the adjustment mechanism, a second telescopic rod rotatably connected to the upper side of the support frame near the left side, the right side of the second telescopic rod rotatably connected to the upper end of the spray gun body, and a vibration mechanism fixedly connected to the lower side of the support frame.
[0009] The adjustment mechanism includes a sliding frame, the inner side of which is slidably connected to the inner side of the support frame, and the outer side of the spray gun body is rotatably connected to the inner side of the sliding frame. Two first telescopic rods are fixedly connected to the front and rear sides of the support frame, and the right side of the first telescopic rods is fixedly connected to the front and rear sides of the sliding frame.
[0010] Preferably, the front and rear sides of the spray gun body are rotatably connected to two rotating frames distributed in the front and rear, and the lower ends of the two rotating frames are fixedly connected to spray pipes.
[0011] Preferably, two heat-insulating shells are fixedly connected to the middle of the front and rear sides of the spray gun body, and motors are fixedly connected to the inner sides of the two heat-insulating shells. The upper side of the rotating frame is fixedly connected to the output end of the motor.
[0012] Preferably, a distance measuring sensor is fixedly connected to the inner right side of the sliding frame, and a receiving plate is fixedly connected to the upper side of the spray gun body.
[0013] Preferably, the vibration mechanism includes a mounting frame, a shock absorber is fixedly connected to the bottom inner side of the mounting frame, a vibration motor is fixedly connected to the upper side of the shock absorber, a connecting seat is fixedly connected to the upper side of the vibration motor, and the upper side of the connecting seat is fixedly connected to the lower side of the support frame.
[0014] Preferably, a plurality of rectangularly distributed third telescopic rods are fixedly connected to the inner sides of the front and rear walls of the mounting frame, and the outer sides of the third telescopic rods are movably sleeved in the insertion holes on the front and rear sides of the connecting seat near the support frame.
[0015] Preferably, a conical block is fixedly connected to one side of each of the third telescopic rods near the support frame.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This utility model provides a novel spray gun. Based on the cooperation of the adjustment mechanism, sliding frame, first telescopic rod, rotating frame, spray pipe, heat insulation shell, motor, distance sensor and receiving plate, the first telescopic rod drives the sliding frame to move, thereby adjusting the lower end of the spray gun body and the distance from the spray pipe to the rear side of the inner wall of the molten iron ladle, which facilitates slag agglomeration. At the same time, the setting of the spray pipe and motor expands the spray range and improves the slag agglomeration efficiency.

Based on the cooperation of a support frame, a vibration mechanism, a mounting frame, a shock absorber, a vibration motor, a connecting seat, and a third telescopic rod, the vibration motor drives the support frame to vibrate, thereby causing the equipment on it to vibrate. This facilitates the shaking off of slag or residual molten iron adhering to the spray gun body, rotating frame, and spray pipe, avoiding the problem of some material remaining when the spray gun is pulled out due to the increased structural complexity of the components inserted into the molten iron.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figures 1-5 As shown, a novel spray gun includes a support frame 1, an adjustment mechanism 2 is slidably connected to the inner side of the support frame 1, a spray gun body 3 is rotatably connected to the inner side of the adjustment mechanism 2, a second telescopic rod 4 is rotatably connected to the upper side of the support frame 1 near the left side, the right side of the second telescopic rod 4 is rotatably connected to the upper end of the spray gun body 3, and a vibration mechanism 5 is fixedly connected to the lower side of the support frame 1.
[0027] The adjustment mechanism 2 includes a sliding frame 21, the inner side of which is slidably connected to the inner side of the support frame 1, and the outer side of the spray gun body 3 is rotatably connected to the inner side of the sliding frame 21. Two first telescopic rods 22 are fixedly connected to the front and rear sides of the support frame 1, and the right side of the first telescopic rods 22 is fixedly connected to the front and rear sides of the sliding frame 21.
[0028] It should be noted that the second telescopic rod 4 and the first telescopic rod 22 are electric push rods that can control their own length, thereby causing the second telescopic rod 4 to drive the spray gun body 3 to rotate on the sliding frame 21. The spray gun body 3 has the same shape as the component with the same function in the reference case, which is existing technology and will not be described in detail here. The lower side of the vibration mechanism 5 is mounted on a lifting device, which can drive the entire device to move up and down. The first telescopic rod 22 can be driven to move left and right, thereby driving the spray gun body 3 to move left and right. The two first telescopic rods 22 are synchronously controlled by an external control device.
[0029] like Figure 5 As shown, two rotating frames 23 are rotatably connected to the front and rear sides of the spray gun body 3, and the lower ends of the two rotating frames 23 are fixedly connected to the spray pipes 24.
[0030] It should be noted that the upper side of the rotating frame 23 is the same as the upper side of the spray gun body 3, both of which are equipped with air pipes. The inner and outer layer structure of the nozzle 24 is the same as that of the spray gun body 3. The difference is that the nozzle 24 is provided with multiple strip-shaped air holes.
[0031] like Figure 5 As shown, two heat insulation shells 25 are fixedly connected to the middle of the front and rear sides of the spray gun body 3. Motors 26 are fixedly connected to the inner side of the two heat insulation shells 25. The upper side of the rotating frame 23 is fixedly connected to the output end of the motor 26.
[0032] It should be noted that the heat insulation shell 25 is used to protect the motor 26. The motor 26 drives the rotating frame 23 to rotate, thereby adjusting the included angle of the two rotating frames 23 to suit the internal shape of the molten iron ladle.
[0033] like Figure 3 , Figure 5 As shown, a distance measuring sensor 27 is fixedly connected to the inner right side of the sliding frame 21, and a receiving plate 28 is fixedly connected to the upper side of the spray gun body 3.
[0034] It should be noted that the distance sensor 27 is used to detect the distance from itself to the receiving plate 28, and then infer the rotation angle of the spray gun body 3. The distance from the distance sensor 27 to the rotation position of the spray gun body 3 remains unchanged, and the distance measuring angle of the distance sensor 27 remains unchanged. The receiving plate 28 rotates with the spray gun body 3, causing the distance between it and the distance sensor 27 to change.
[0035] like Figure 2 , Figure 4 As shown, the vibration mechanism 5 includes a mounting frame 51, a shock absorber 52 is fixedly connected to the bottom inner side of the mounting frame 51, a vibration motor 53 is fixedly connected to the upper side of the shock absorber 52, a connecting seat 54 is fixedly connected to the upper side of the vibration motor 53, and the upper side of the connecting seat 54 is fixedly connected to the lower side of the support frame 1.
[0036] It should be noted that the vibration motor 53 can drive the support frame 1 to vibrate, which in turn drives the support frame 1, the adjustment mechanism 2 and the spray gun body 3 to vibrate, thereby shaking off the residue on them. The shock absorber 52 is used to prevent the vibration generated by the vibration motor 53 from being transmitted downward.
[0037] like Figure 4 As shown, several rectangularly distributed third telescopic rods 55 are fixedly connected to the inner sides of the front and rear walls of the mounting bracket 51. The outer side of the third telescopic rods 55 is movably sleeved in the insertion holes on the front and rear sides of the connecting seat 54 near the support frame 1.
[0038] It should be noted that the third telescopic rod 55 is an electric push rod that can control its own length. When the third telescopic rod 55 is inserted into the socket, the position of the support frame 1 is fixed.
[0039] like Figure 4 As shown, several third telescopic rods 55 are fixedly connected to conical blocks on the side near the support frame 1.
[0040] It should be noted that the outer side of the conical block is equipped with a rubber sleeve. Due to its structural design and the setting of the rubber sleeve, the problem of the third telescopic rod 55 being unable to fix the connecting seat 54 when the insertion hole is subjected to great wear is avoided.
[0041] The working principle of this utility model is as follows: First, the second telescopic rod 4 and the first telescopic rod 22 are electric push rods that can control their own length. This allows the second telescopic rod 4 to drive the spray gun body 3 to rotate on the sliding frame 21. The spray gun body 3 has the same shape as the component with the same function in the reference case, which is existing technology and will not be described in detail here. The lower side of the vibration mechanism 5 is mounted on a lifting device, which can drive the entire device to move up and down. The first telescopic rod 22 can drive left and right movement, thereby driving the spray gun body 3 to move left and right. The upper side of the rotating frame 23 is the same as the upper side of the spray gun body 3, both of which are equipped with air pipes. The inner and outer layer structure of the nozzle 24 is the same as that of the spray gun body 3. The difference is that the nozzle 24 is provided with multiple strip-shaped air holes. The heat insulation shell 25 is used to protect the motor 26. The motor 26 drives the rotating frame 23 to rotate, thereby adjusting the angle between the two rotating frames 23 to suit the internal shape of the molten iron ladle. The first telescopic rod 22 drives the sliding frame 21 to move, thereby adjusting the lower end of the spray gun body 3 and the nozzle 24 into the molten iron ladle. The distance to the back of the wall facilitates slag accumulation. Simultaneously, the arrangement of the nozzle 24 and motor 26 expands the air jet range and improves slag accumulation efficiency. Finally, the vibration motor 53 drives the support frame 1 to vibrate, which in turn vibrates the support frame 1, the adjustment mechanism 2, and the spray gun body 3, shaking off any residue. The shock absorber 52 prevents the vibration generated by the vibration motor 53 from being transmitted downwards. The third telescopic rod 55 is an electric push rod that can control its length. When the third telescopic rod 55 is inserted into the insertion hole, the position of the support frame 1 is fixed. The outer side of the conical block is equipped with a rubber sleeve. Due to its structural design and the rubber sleeve, the problem of the third telescopic rod 55 being unable to secure the connecting seat 54 when the insertion hole is subjected to significant wear is avoided. The vibration motor 53 drives the support frame 1 to vibrate, which in turn causes the equipment on it to vibrate, facilitating the shaking off of slag or residual molten iron adhering to the spray gun body 3, the rotating frame 23, and the nozzle 24. This avoids the problem of some material remaining when the spray gun is pulled out due to the increased structural complexity of the components inserted into the molten iron.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
