Description

Technical Field

[0001] The utility model relates to the technical field of burden production, in particular to a cooling device for metallurgical burden production. Background Technique

[0002] Metallurgical burden is the raw and auxiliary materials in the steel smelting production, mainly used in the steelmaking process. By adding different burdens, the complex metals contained in the burden are oxidized. The metallurgical burden cooling device is mainly used to cool the high-temperature burden in heating equipment such as blast furnaces and steelmaking furnaces to ensure that the temperature of the burden drops to a safe range for subsequent processing and transportation.

[0003] After retrieval, the utility model with the Chinese patent publication number CN209584291U discloses a rapid cooling device for metallurgical burden production, including a water tank body. The bottom of the water tank body is connected with a motor through a motor seat. The output shaft of the motor is connected with a stirring frame. The top of the water tank body is rotatably connected with a sealing cover through a hinge. A cooling box is arranged on the right side of the water tank body. The cooling box consists of a box body, a box cover and ice crystal bags. A through hole is arranged between the water tank body and the cooling box.

[0004] The above device realizes the cooling purpose of the burden through the water tank. However, due to the weight of the burden itself, it will sink to the bottom of the water, which will cause the removal process to be inconvenient, and then affect the processing efficiency, and there is room for improvement. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cooling device for metallurgical burden production to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A cooling device for metallurgical burden production, including a cooling box. A storage component is installed outside the cooling box. The storage component includes a moving frame placed outside the cooling box. One end of the top of the moving frame is rotatably connected with a feeding pipe. One end of the bottom of the feeding pipe is rotatably connected with a storage tank. The storage tank can completely enter the internal space of the cooling box. A hydraulic cylinder is fixedly installed on the inner wall of the bottom of the moving frame. One end of the top of the hydraulic cylinder is fixedly connected with a connecting ring. An extension frame is fixedly connected to the outer wall of one side of the feeding pipe. The connecting ring is slidably sleeved outside the extension frame.

[0007] As a further preference of the technical solution, a reinforcing frame is rotatably sleeved outside the storage tank. One end of the reinforcing frame is fixedly connected with the feeding pipe.

[0008] After the processing is completed, the furnace charge stored can be quickly discharged to the outside, thus eliminating the subsequent fishing process, which is beneficial to improving the processing efficiency of the furnace charge. After the processing is completed, the hydraulic cylinder at the top of the moving frame is started, and the hydraulic cylinder drives the connecting ring to move synchronously. The connecting ring can drive the guide pipe to flip on the top of the moving frame through the extension frame, and the storage tank connected to the guide pipe will also be driven to tilt. The furnace charge inside the storage tank will slide along its slope into the guide pipe and then directly slide to the outside.

[0009] As a further preference of this technical solution, a transmission assembly is installed at the bottom of the moving frame. The transmission assembly includes a reciprocating screw rod threadedly connected to the bottom of the moving frame. A convex block adapted to the reciprocating screw rod is provided inside the moving frame. Two extension plates are fixedly connected to one side of the cooling box. The reciprocating screw rod is rotatably connected between the two extension plates. An electric motor is fixedly installed outside one of the extension plates, and the rotating shaft of the electric motor and one end of the reciprocating screw rod are coaxially fixed.

[0010] As a further preference of this technical solution, a rubber ring is fixedly sleeved on both ends of the circumferential outer wall of the storage tank. A bearing plate is provided on the inner wall of the bottom of the cooling box, and the two rubber rings can contact the top wall of the bearing plate.

[0011] Start the electric motor outside the extension plate. The rotating shaft of the electric motor drives the reciprocating screw rod to rotate. The moving frame is sleeved outside the two limit rods and can only move horizontally. Therefore, the reciprocating screw rod can drive the moving frame to move left and right reciprocally. The moving frame can drive the storage tank to move synchronously through the guide pipe. Furthermore, the furnace charge accumulated inside the storage tank will also move back and forth inside the cooling box, enabling the cooling water around these furnace charges to be continuously replaced, which is beneficial to improving the cooling efficiency. And the rubber ring outside the storage tank contacts the bearing plate. Under the action of friction, the storage tank can be rotated while moving, avoiding the furnace charge at the middle position having too high a temperature and being unable to be quickly cooled.

[0012] As a further preference of this technical solution, a plurality of limit rods are fixedly connected between the two extension plates, and the moving frame is slidably sleeved outside the plurality of limit rods.

[0013] As a further preference of this technical solution, a heat exchanger is fixedly installed on the outer wall of one end of the cooling box, and a pump body is fixedly installed on the outer wall of one side of the cooling box. The heat exchanger, the pump body and the cooling box are connected by pipelines.

[0014] As a further preference of this technical solution, the upper surface of the bearing plate and the two rubber rings are both made of heat-resistant rubber.

[0015] The utility model provides a cooling device for metallurgical furnace charge production, which has the following beneficial effects:

[0016] (1) By providing a storage component, the utility model can quickly discharge the stored furnace charge to the outside after processing, thus eliminating the subsequent fishing process, which is beneficial to improving the processing efficiency of the furnace charge. After processing, the hydraulic cylinder at the top of the moving frame is started, and the hydraulic cylinder drives the connecting ring to move synchronously. The connecting ring drives the guide pipe to flip on the top of the moving frame through the extension frame, and the storage tank connected to the guide pipe will also be driven to tilt. The furnace charge inside the storage tank will slide along its slope into the guide pipe and then directly slide to the outside.

[0017] (2) By providing a transmission component, when the motor outside the extension plate is started, the rotating shaft of the motor drives the reciprocating lead screw to rotate. The moving frame is sleeved outside the two limit rods and can only move horizontally. Therefore, the reciprocating lead screw can drive the moving frame to move left and right reciprocally. The moving frame drives the storage tank to move synchronously through the guide pipe, and then the furnace charge accumulated inside the storage tank will also move back and forth inside the cooling box, enabling the cooling water around these furnace charges to be continuously replaced, which is beneficial to improving the cooling efficiency. Moreover, the rubber ring outside the storage tank contacts the bearing plate, and under the action of friction, the storage tank can rotate while moving, preventing the furnace charge in the middle position from having too high a temperature and not being cooled quickly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model.

[0024] The utility model provides the following technical solutions: As Figure 2, Figure 3 and Figure 4 As shown in Figure 3 and Figure 4 , in this embodiment, a cooling device for metallurgical burden production includes a cooling box 1. A storage assembly 4 is installed outside the cooling box 1. The storage assembly 4 includes a moving frame 401 placed outside the cooling box 1. One end of the top of the moving frame 401 is rotatably connected to a feeding pipe 403. One end of the bottom of the feeding pipe 403 is rotatably connected to a storage tank 404. The storage tank 404 can completely enter the internal space of the cooling box 1. A hydraulic cylinder 402 is fixedly installed on the inner wall of the bottom of the moving frame 401. One end of the top of the hydraulic cylinder 402 is fixedly connected to a connecting ring 406. An extension frame 405 is fixedly connected to the outer wall of one side of the feeding pipe 403. The connecting ring 406 is slidably sleeved outside the extension frame 405.

[0025] A reinforcing frame 407 is rotatably sleeved outside the storage tank 404. One end of the reinforcing frame 407 is fixedly connected to the feeding pipe 403, making the state between the storage tank 404 and the feeding pipe 403 more stable and not affecting the subsequent rotation of the storage tank 404.

[0026] After the processing is completed, start the hydraulic cylinder 402 at the top of the moving frame 401. The hydraulic cylinder 402 drives the connecting ring 406 to move synchronously. The connecting ring 406 can drive the feeding pipe 403 to flip on the top of the moving frame 401 through the extension frame 405. The storage tank 404 connected to the feeding pipe 403 will also be driven to tilt. The burden inside the storage tank 404 will slide along its slope into the feeding pipe 403 and then directly slide to the outside.

[0027] As Figure 1 and Figure 4 shown, a transmission assembly 5 is installed at the bottom of the moving frame 401. The transmission assembly 5 includes a reciprocating lead screw 502 threadedly connected to the bottom of the moving frame 401. A convex block adapted to the reciprocating lead screw 502 is provided inside the moving frame 401. Two extension plates 501 are fixedly connected to one side of the cooling box 1. The reciprocating lead screw 502 is rotatably connected between the two extension plates 501. A motor 504 is fixedly installed outside one of the extension plates 501. The rotating shaft of the motor 504 and one end of the reciprocating lead screw 502 are coaxially fixed.

[0028] A rubber ring 505 is fixedly sleeved on both ends of the circumferential outer wall of the storage tank 404. A receiving plate 506 is provided on the inner wall of the bottom of the cooling box 1. The two rubber rings 505 can contact the top wall of the receiving plate 506.

[0029] A plurality of limiting rods 503 are fixedly connected between the two extension plates 501. The moving frame 401 is slidably sleeved outside the plurality of limiting rods 503. With their cooperation, the state of the moving frame 401 can be ensured to be stable enough.

[0030] Start the motor 504 outside the extension plate 501. The rotating shaft of the motor 504 drives the reciprocating lead screw 502 to rotate. The moving frame 401 is sleeved outside the two limiting rods 503 and can only move horizontally. Therefore, the reciprocating lead screw 502 can drive the moving frame 401 to move back and forth left and right. The moving frame 401 can drive the storage tank 404 to move synchronously through the material guiding pipe 403. Furthermore, the furnace charge accumulated inside the storage tank 404 will also move back and forth inside the cooling box 1, enabling the cooling water around these furnace charges to be continuously replaced, which is beneficial to improving the cooling efficiency. And the rubber ring 505 outside the storage tank 404 contacts the bearing plate 506. Under the action of friction, the storage tank 404 can be rotated while moving, avoiding the furnace charge at the middle position having too high a temperature and being unable to be quickly cooled.

[0031] As Figure 1 and Figure 2 shown, a heat exchanger 2 is fixedly installed on the outer wall of one end of the cooling box 1, and a pump body 3 is fixedly installed on the outer wall of one side of the cooling box 1. The heat exchanger 2, the pump body 3 and the cooling box 1 are connected and communicated through pipelines. Start the pump body 3 to pump the water inside the cooling box 1 into the heat exchanger 2. The heat therein will be absorbed by the absorbent liquid inside the heat exchanger 2, and then it will circulate back into the cooling box 1 through the pipeline, avoiding the cooling water having too high a temperature and reducing the cooling effect.

[0032] As Figure 1 and Figure 2 shown, the upper surface of the bearing plate 506 and the two rubber rings 505 are both made of heat-resistant rubber to prevent the two from being damaged when being in a high-temperature environment for a long time.

[0033] The utility model provides a cooling device for metallurgical furnace charge production, and the specific working principle is as follows:

[0034] When the device is working, the furnace charge to be processed is introduced into the material guiding pipe 403. Subsequently, these furnace charges will be centrally stacked in the storage tank 404. Then, the motor 504 outside the extension plate 501 is started. The rotating shaft of the motor 504 drives the reciprocating lead screw 502 to rotate. The moving frame 401 is sleeved outside the two limiting rods 503 and can only move horizontally. Therefore, the reciprocating lead screw 502 can drive the moving frame 401 to move left and right reciprocally. The moving frame 401 can drive the storage tank 404 to move synchronously through the material guiding pipe 403. Thus, the furnace charges stacked inside the storage tank 404 will also move back and forth inside the cooling tank 1, enabling the continuous replacement of the cooling water around these furnace charges, which is beneficial to improving the cooling efficiency. Moreover, the rubber ring 505 outside the storage tank 404 contacts the bearing plate 506. Under the action of the frictional force, the storage tank 404 can be made to rotate while moving, avoiding the over-high temperature of the furnace charges at the middle position and being unable to be quickly cooled. After the processing is completed, the hydraulic cylinder 402 on the top of the moving frame 401 is started. The hydraulic cylinder 402 drives the connecting ring 406 to move synchronously. The connecting ring 406 can drive the material guiding pipe 403 to flip on the top of the moving frame 401 through the extension frame 405. The storage tank 404 connected to the material guiding pipe 403 will also be driven to tilt. The furnace charges inside the storage tank 404 will slide down along its slope into the material guiding pipe 403 and then directly slide to the outside.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
