Description

Technical Field

[0001] This utility model relates to the field of metallurgical technology, and in particular to a safe addition device for metallurgical auxiliary materials. Background Technology

[0002] Metallurgy is a long-standing and crucial engineering technology that involves extracting metals or metal compounds from ores and processing these metals into metallic materials with specific properties through a series of processing methods.

[0003] Reference to the utility model patent with authorization announcement number CN213678776U, a metallurgical safety intelligent auxiliary material adding device is disclosed, including a working frame. The upper surface of the working frame is provided with a fixed rack, and the surface of the fixed rack is equipped with a moving gear. A moving support frame is installed between the moving gears. An auxiliary material adding box is installed on the surface of the main body of the hanger. The two sides of the auxiliary material adding box are fixed to the surface of the main body of the hanger by welding plates. The surface of the welding plates is provided with threaded fixing holes. An auxiliary material storage bin is provided inside the auxiliary material adding box. A servo motor is installed on one side of the auxiliary material adding box. The output end of the servo motor is rotatably connected to a lead screw installed inside the auxiliary material storage bin through a rotating shaft. A pusher plate is installed on the surface of the lead screw.

[0004] In the aforementioned patent, a pusher plate is driven by a lead screw to slide in the auxiliary material storage bin, so that the auxiliary material is pushed out of the storage bin and added to the metallurgical furnace. However, this method of adding auxiliary materials makes it difficult to precisely control the dosage of the added auxiliary materials. In addition, the auxiliary materials fall directly into the metallurgical furnace and tend to accumulate, making it difficult to fully react with the molten metal in the metallurgical furnace. To solve the defects in the above-mentioned technology, we propose a safe device for adding metallurgical auxiliary materials. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a safe addition device for metallurgical auxiliary materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A safe addition device for metallurgical auxiliary materials includes a metallurgical furnace. A flip-top cover is provided on the upper side of the metallurgical furnace, and an auxiliary material addition mechanism is provided on the flip-top cover. The auxiliary material addition mechanism includes an auxiliary material cylinder, a feeding pipe fixedly connected to the bottom of the auxiliary material cylinder, an expanding cone fixedly installed at the lower end of the feeding pipe, a solenoid valve fixedly installed on the feeding pipe, a controller fixedly installed on the upper side of the auxiliary material cylinder, several venting bends fixedly connected to the outer wall of the expanding cone, a protective cover provided inside the expanding cone, several connecting rods fixedly connected between the protective cover and the inner wall of the expanding cone, a built-in motor fixedly installed inside the protective cover, a turntable fixedly installed on the output end of the built-in motor, and several blades fixedly installed on the side wall of the turntable.

[0008] Furthermore, the flip cover has an opening, and the bottom of the outwardly expanding cone is connected to the opening.

[0009] Furthermore, the protective cover is conical in shape, and supports are symmetrically fixedly installed on both sides of the auxiliary material cylinder, with the bottom of the supports fixedly connected to the upper side of the flip cover.

[0010] Furthermore, a feeding port is fixedly installed on the upper side of the auxiliary material cylinder, and a sealing cap is fitted on the upper side of the feeding port.

[0011] Furthermore, a rotating shaft is fixedly installed on the side of the flip cover, and a bearing seat is fixedly installed on the side wall of the metallurgical furnace, with the rotating shaft and the bearing seat being rotatably connected.

[0012] Furthermore, a folding plate is fixedly installed on the side wall of the metallurgical furnace, and a synchronous electric telescopic rod is symmetrically hinged between the folding plate and the flip cover.

[0013] Furthermore, a reinforcing connecting plate is fixedly connected between the folding plate and the side wall of the metallurgical furnace.

[0014] Compared with related technologies, the metallurgical auxiliary material safety addition device proposed in this utility model has the following beneficial effects:

[0015] This utility model discloses a safe addition device for metallurgical auxiliary materials. The device employs an auxiliary material addition mechanism that combines an auxiliary material cylinder, a controller, a feeding pipe, a solenoid valve, and an expanding cone. The controller precisely controls the amount of auxiliary material added to the inner side of the auxiliary material cylinder by controlling the opening time of the solenoid valve. During the addition of auxiliary material, the built-in motor inside the expanding cone drives the blades on the turntable to rotate at high speed, creating a downward blowing effect inside the cone. Simultaneously, the rotating blades disperse the added auxiliary material, ensuring it is evenly added to the metallurgical furnace. This allows the auxiliary material to mix and react uniformly with the molten metal inside the furnace, improving its effectiveness and enhancing its practicality. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-6 A metallurgical auxiliary material safety addition device includes a metallurgical furnace 1, a flip cover 3 on the upper side of the metallurgical furnace 1, and an auxiliary material addition mechanism 5 on the flip cover 3. The auxiliary material addition mechanism 5 includes an auxiliary material cylinder 51, a feeding pipe 56 fixedly connected to the bottom of the auxiliary material cylinder 51, an expanding cone 58 fixedly installed at the lower end of the feeding pipe 56, a solenoid valve 57 fixedly installed on the feeding pipe 56, a controller 53 fixedly installed on the upper side of the auxiliary material cylinder 51, several ventilation bends 59 fixedly connected to the outer wall of the expanding cone 58, a protective cover 510 on the inner side of the expanding cone 58, several connecting rods 511 fixedly connected between the protective cover 510 and the inner wall of the expanding cone 58, an internal motor 512 fixedly installed on the inner side of the protective cover 510, a turntable 513 fixedly installed on the output end of the internal motor 512, and several blades 514 fixedly installed on the side wall of the turntable 513.

[0025] With the above configuration, the auxiliary materials stored inside the auxiliary material cylinder 51 can be fed into the metallurgical furnace 1 through the feeding pipe 56. After feeding, the auxiliary materials are fed into the metallurgical furnace 1 through the expanding cone 58 and mixed with the molten metal in the metallurgical furnace 1. When the built-in motor 512 starts and drives the blades 514 to rotate, a downward blowing effect is generated. The expanding cone 58 is connected to a ventilation bend 59 to provide an air inlet channel. When the blades 514 rotate, they can disperse the fed auxiliary materials, so that the auxiliary materials fed from the expanding cone 58 are evenly dispersed and fed into the metallurgical furnace 1, so that the fed auxiliary materials can be evenly fed into the molten metal.

[0026] In this method, a rotating shaft 4 is fixedly installed on the side of the flip cover 3, and a bearing seat 2 is fixedly installed on the side wall of the metallurgical furnace 1. The rotating shaft 4 is rotatably connected to the bearing seat 2.

[0027] With the above configuration, the bearing seat 2 on the side of the metallurgical furnace 1 provides a rotational support point for the flip cover 3.

[0028] In this method, a folding plate 6 is fixedly installed on the side wall of the metallurgical furnace 1, and a synchronous electric telescopic rod 7 is symmetrically hinged between the folding plate 6 and the flip cover 3.

[0029] With the above-mentioned setup, the synchronous electric telescopic rod 7 can be activated to retract, which can drive the flip cover 3 to flip upwards for opening the furnace.

[0030] In this method, a reinforcing connecting plate 8 is fixedly connected between the folding plate 6 and the side wall of the metallurgical furnace 1.

[0031] By setting up the connection plate 8 as described above, the lateral support stability of the folded plate 6 is improved.

[0032] In this method, the flip cover 3 has an opening 9, and the bottom of the outwardly expanding cone 58 is connected to the opening 9.

[0033] With the above-mentioned setup, port 9 provides a feeding channel for the addition of auxiliary materials.

[0034] In this configuration, the protective cover 510 is conical in shape, and the auxiliary material cylinder 51 is symmetrically fixedly mounted with supports 52 on both sides. The bottom of the supports 52 is fixedly connected to the upper side of the flip cover 3.

[0035] With the above-described configuration, the support 52 provides support for the auxiliary material cylinder 51.

[0036] In this method, a feeding port 54 is fixedly installed on the upper side of the auxiliary material cylinder 51, and a sealing cap 55 is fitted on the upper side of the feeding port 54.

[0037] With the above-described setup, the feeding port 54 is used to add auxiliary materials.

[0038] The working principle of the metallurgical auxiliary material safety addition device provided by this utility model is as follows:

[0039] In use, open the sealing cap 55 on the feeding port 54 of the auxiliary material cylinder 51, and add metallurgical auxiliary materials into the auxiliary material cylinder 51 through the feeding port 54. After the materials are added, close the sealing cap 55 again to ensure a seal. Then, start the synchronous electric telescopic rod 7 to retract it, causing the flip cover 3 to rotate upward around the axis of rotation, so that the flip cover 3 is slightly opened to provide an air outlet. Subsequently, the controller 53 controls the solenoid valve 57 to open according to the preset program or command, so that the auxiliary materials fall from the auxiliary material cylinder 51 through the feeding pipe 56 into the outer expansion cone 58. At the same time, start the built-in motor 512 to drive the blades 514 to rotate at high speed, generating a downward airflow that blows away and evenly disperses the falling auxiliary materials. The dispersed auxiliary materials are evenly fed into the molten metal in the metallurgical furnace 1 through the opening 9 at the bottom of the outer expansion cone 58. After the auxiliary materials are fed, close the solenoid valve 57, and the controller 53 issues a command to extend the synchronous electric telescopic rod 7, pushing the flip cover 3 to rotate downward around the axis of rotation 4. The entire metallurgical furnace returns to a closed state and continues the metallurgical reaction process.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
