Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, specifically to an intermittent feeding device for metallurgy. Background Technology

[0002] Metallurgy refers to the process and technology of extracting metals or metal compounds from minerals and processing them into metallic materials with certain properties using various processing methods. The main technologies of metallurgy include pyrometallurgy, hydrometallurgy, and electrometallurgy. With the successful application of physical chemistry in metallurgy, the precise quantitative feeding of materials in metallurgical industrial production is a key link to ensure product quality and control production costs. Especially in processes such as smelting and rolling, the amount of raw materials and additives added must strictly meet the formula requirements. If the amount of materials added deviates too much, it will not only lead to an imbalance in the chemical composition and performance fluctuations of metallurgical products, but may also cause problems such as equipment overload and process parameter disorder.

[0003] Currently, traditional metallurgical feeding equipment mostly uses the method of directly feeding materials from storage tanks. Due to the lack of a real-time weighing structure, it is difficult to accurately monitor the feeding amount. Especially when processing materials with uneven particle size and varying moisture content, the feeding error is more obvious, resulting in unstable batch product quality. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an intermittent feeding device for metallurgy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intermittent feeding device for metallurgy, comprising a storage tank, a receiving tank, a weighing platform, and a support frame. The top of the support frame is provided with a support plate, and the lower end of the storage tank is provided with a discharge pipe that penetrates the support plate. A first motor is fixedly installed above the storage tank, and the output end of the first motor is provided with a spiral conveying rod inserted into the discharge pipe. The outer wall of the spiral conveying rod is close to the inner wall of the discharge pipe.

[0006] The top of the storage tank is rotatably equipped with a ring frame, and the inner side of the ring frame is provided with multiple positioning plates. The lower end of the positioning plate is provided with a stirring rod that is inserted into the storage tank.

[0007] The lower end of the pallet is provided with a limiting frame, and a third motor is provided on one side of the limiting frame. The weighing platform is located below the pallet, and a base is provided at the lower end of the weighing platform. The output end of the third motor is provided with a drive shaft that passes through the base, and the base is fixedly connected to the drive shaft. The detection end of the weighing platform is provided with a weighing detection plate, and the receiving tank is fixed at the upper end of the weighing detection plate.

[0008] To facilitate assembly of the storage tank on the pallet, the present invention includes the following improvement: the storage tank is fixed to the upper end of the pallet by multiple support rods, and the lower end of the support rods is fixed to the upper end of the pallet by screws.

[0009] To facilitate the assembly of the first motor above the storage tank, the present invention includes an improvement in which the first motor is fixed above the storage tank by a support rod, and the bottom end of the support rod is fixed to both sides of the storage tank by screws.

[0010] To make the annular frame rotate more smoothly on top of the storage tank, the present invention includes the following improvements: the lower end of the annular frame is provided with an annular groove, the upper end of the storage tank is inserted into the annular groove and rotatably connected to the annular frame through a bearing, a gear ring is provided on the periphery of the annular frame, a second motor is provided on one side of the storage tank, and the output end of the second motor is provided with a gear that meshes with the gear ring.

[0011] To facilitate the assembly of the stirring rod on the positioning plate, the improvement of this utility model is that the top end of the stirring rod is fixed to the lower end of the positioning plate by screws.

[0012] Furthermore, an improvement of this utility model is that the weighing detection plate is made of metal plate, and the receiving tank is welded to the upper end of the weighing detection plate.

[0013] Furthermore, an improvement of this utility model is that the support frame, tray, and limiting frame are an integrated structure.

[0014] Furthermore, an improvement of this utility model is that the first motor, the second motor, and the third motor are all servo motors.

[0015] The support frame is installed above the feeding port of the metallurgical equipment. The first and third motors are started intermittently. After the first motor starts, the screw conveyor will rotate, which will provide a screw conveying effect for the metallurgical raw materials in the storage tank, so that the metallurgical raw materials in the storage tank are added into the receiving tank. At this time, the weighing platform can weigh the receiving tank in real time. When the weight reaches the preset value, the first motor starts, and then the third motor starts. The drive shaft will rotate the weighing platform 180 degrees, so that the receiving tank rotates 180 degrees at the limit frame, so that the metallurgical raw materials in the receiving tank are poured into the metallurgical equipment through the feeding port.

[0016] During the startup of the first motor, the second motor starts, causing the gear to rotate through the gear ring and drive the ring frame to rotate. This enables multiple stirring rods to rotate inside the storage tank, providing a stirring effect for the metallurgical raw materials in the storage tank, and allowing the screw conveyor to feed materials more smoothly.

[0017] Compared with the prior art, the beneficial effects of this utility model are that by monitoring the weight of the receiving tank in real time through the weighing platform, the intermittent and precise quantitative feeding of metallurgical raw materials can be realized, avoiding product quality fluctuations and equipment malfunctions caused by deviations in the amount of material fed, and significantly improving the chemical composition stability and performance consistency of metallurgical products.

[0018] The continuous stirring action of the stirring rod in the storage tank effectively disperses raw material particles, prevents damp or sticky raw materials from clumping, ensures smooth screw conveying, reduces equipment downtime, and improves production efficiency.

[0029] Please see Figures 1-5 This utility model discloses an intermittent feeding device for metallurgy, comprising a storage tank 1, a receiving tank 19, a weighing platform 16, and a support frame 11. The top of the support frame 11 is provided with a support plate, and the lower end of the storage tank 1 is provided with a discharge pipe 2 that penetrates the support plate. A first motor 3 is fixedly installed above the storage tank 1. The output end of the first motor 3 is provided with a spiral conveying rod 4 that is inserted into the discharge pipe 2. The outer wall of the spiral conveying rod 4 is close to the inner wall of the discharge pipe 2, and the gap between the outer wall of the spiral conveying rod 4 and the inner wall of the discharge pipe 2 is ≤1mm.

[0030] The top of the storage tank 1 is rotatably equipped with an annular frame 7, and the inner side of the annular frame 7 is provided with multiple positioning plates 20. The lower end of the positioning plate 20 is provided with a stirring rod 10 that is inserted into the storage tank 1.

[0033] The support frame 11 of the equipment is securely installed above the feeding port of the metallurgical equipment.

[0034] During operation, the first motor 3 and the third motor 14 start intermittently. When the first motor 3 starts, the screw conveyor 4 at its output end begins to rotate. Through the screw conveying action, the metallurgical raw materials in the storage tank 1 are evenly pushed into the receiving tank 19 below. During this process, the weighing platform 16 located below the receiving tank 19 monitors the weight change of the receiving tank 19 in real time.

[0035] When the weight of the raw material in the receiving tank 19 reaches the preset value, the first motor 3 stops running, and the screw conveyor 4 stops feeding. At this time, the third motor 14 starts, and drives the weighing platform 16 to rotate 180 degrees through the drive shaft 15, so that the receiving tank 19 rotates synchronously to above the feeding port, and the metallurgical raw material in the receiving tank 19 is accurately fed into the metallurgical equipment through the feeding port.

[0036] The lower end of the ring frame 7 is provided with an annular groove 9. The upper end of the storage tank 1 is inserted into the annular groove 9 and is rotatably connected to the ring frame 7 through a bearing. The ring frame 7 is provided with a toothed ring 8 on its periphery. The storage tank 1 is provided with a second motor 5 on one side. The output end of the second motor 5 is provided with a gear 6 that meshes with the toothed ring 8.

[0037] During the operation of the first motor 3, the second motor 5 starts synchronously, driving the gear 6 to mesh with the gear ring 8 on the outer periphery of the ring frame 7, thus rotating the ring frame 7. The multiple stirring rods 10 inside the ring frame 7 then rotate within the storage tank 1, stirring the raw materials to prevent clumping or accumulation and ensuring smooth feeding by the screw conveyor 4.

[0038] The design of the third motor 14 driving the receiving tank 19 to rotate 180 degrees enables the intermittent switching of the feeding process, allowing the equipment to adapt to the periodic feeding requirements of different metallurgical processes and improve process flexibility.

[0041] The integrated support frame 11, tray and limit frame 13 design, as well as the screw fixing and bearing connection, ensure the overall structure of the equipment is stable, reduce vibration and noise, and extend the service life of the equipment. The screw fixing method makes it easy to assemble the storage tank 1, the first motor 3 and the stirring rod 10.
