Description

Technical Field

[0001] This utility model relates to the technical field of zinc alloy production equipment, specifically a precise feeding mechanism for zinc alloy proportioning. Background Technology

[0002] Zinc alloys are alloys composed of zinc as the base metal and one or more other elements (such as aluminum, copper, magnesium, etc.). Zinc alloys are one of the most widely used non-ferrous metal alloy materials in industry, especially in the die-casting field. In the production process of zinc alloys, zinc is used as the main material and fed into a smelting furnace. Additional raw materials are added to the furnace according to the required proportions, and after smelting, a zinc alloy is formed.

[0003] In the production process of zinc alloys, in order to improve product quality, it is necessary to accurately weigh and proportion the added raw materials. The added raw materials are mostly in granular form or metal ingots. At the same time, various metal added raw materials are added to the smelting furnace in multiple batches according to the smelting requirements. The existing feeding device is directly installed on the outside of the smelting furnace. When adding raw materials, they are directly fed into the furnace body through the feeding device. The raw materials added directly tend to accumulate on one side of the furnace body, which leads to the accumulation and clumping of raw materials. At the same time, the raw materials accumulated on one side of the furnace body are heated slowly, which slows down the melting speed of the metal raw materials and reduces the melting uniformity of the raw materials, thus prolonging the smelting cycle.

[0004] To address these issues, this invention provides a precise feeding mechanism for zinc alloy proportions. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a precise feeding mechanism for zinc alloy proportioning, thus solving the aforementioned problems.

The mixing trough is provided in three sets. A weighing frame is installed inside the mixing trough. A weighing hopper is installed inside the weighing frame. A weighing sensor is installed between the weighing frame and the weighing hopper. An electromagnetic valve is installed on the lower side of the weighing hopper. The top of the smelting furnace is fixedly connected to a furnace cover, and a feeding device is installed on the top of the furnace cover; The feeding component includes a connecting ring fixedly connected to the top of the furnace cover, a rotating ring rotatably connected to the top of the connecting ring, a feeding pipe fixedly connected to the top of the rotating ring, a hopper fixedly connected to one end of the feeding pipe, and a driving component installed between the connecting ring and the rotating ring.

[0012] This invention provides a precise feeding mechanism for zinc alloy proportioning. Compared with the prior art, it has the following advantages: This precise feeding mechanism for zinc alloy proportioning uses a weigher at the bottom of the unloading plate to accurately weigh the raw materials, improving the accuracy of zinc alloy proportioning during production. Simultaneously, during feeding, a rotating ring that can rotate at the top of the connecting ring drives the feeding pipe to rotate as well, ensuring that the proportioned raw materials are evenly distributed inside the smelting furnace. This prevents the raw materials from accumulating on one side of the furnace during feeding, thus avoiding clumping. Furthermore, the evenly distributed raw materials are heated uniformly, accelerating the melting efficiency and shortening the metal smelting cycle. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0016] Please see Figure 1-6 A precise feeding mechanism for zinc alloy proportioning includes a smelting furnace 1, a support 2 fixedly connected to one side of the smelting furnace 1, a proportioning box 3 fixedly connected to one end of the support 2, a guide pipe 4 fixedly connected to the top of the proportioning box 3, and a proportioning component 5 installed inside the proportioning box 3. The proportioning component 5 includes a mixing trough 501 inside the proportioning box 3. The mixing trough 501 is provided in three sets. A weighing frame 502 is installed inside the mixing trough 501. A weighing hopper 503 is installed inside the weighing frame 502. A weighing sensor 504 is installed between the weighing frame 502 and the weighing hopper 503. A solenoid valve 505 is installed on the lower side of the weighing hopper 503. A furnace cover 6 is fixedly connected to the top of the smelting furnace 1, and a feeding component 7 is installed on the top of the furnace cover 6; The feeding component 7 includes a connecting ring 701 fixedly connected to the top of the furnace cover 6, a rotating ring 702 rotatably connected to the top of the connecting ring 701, a feeding pipe 703 fixedly connected to the top of the rotating ring 702, a hopper 704 fixedly connected to one end of the feeding pipe 703, and a driving component 8 installed between the connecting ring 701 and the rotating ring 702.

[0017] The load cell 504 has three sets arranged at equal intervals, and the model number of the load cell 504 is CH-L6H5.

[0018] The driving component 8 includes a cavity connecting plate 801 fixedly connected to the outside of the connecting ring 701. A servo motor 802 is fixedly connected to the top of the cavity connecting plate 801. A gear 803 is fixedly connected to the output end of the servo motor 802. The gear 803 is installed inside the cavity connecting plate 801. A gear ring 804 is fixedly connected to the outside of the rotating ring 702. The gear 803 and the gear ring 804 mesh with each other. A material hole 805 is opened on the top of the furnace cover 6.

[0019] The bottom of the mixing tank 3 is fixedly connected to a clamping plate 9.

[0020] In this embodiment, the guide pipe 4 at the top of the proportioning tank 3 is connected to the raw material tank. During the zinc alloy smelting process, the raw material in the external raw material tank falls from the guide pipe 4 into the weighing hopper 503 of the proportioning tank 3's internal batching trough 501. At this time, the weighing sensor 504 between the weighing frame 502 and the weighing hopper 503 weighs the raw material in the weighing hopper 503. When the weight of the raw material reaches the proportioning requirement, the external raw material tank stops discharging. Simultaneously, the solenoid valve 505 opens, allowing the weighed raw material to fall into the hopper 704. During the feeding process, the servo motor 802 drives the gear 803 fixed at the output end to rotate inside the cavity connecting plate 801. The rotating gear 803 drives the rotating ring 702 connected to the gear ring 804 to rotate inside the connecting ring 701, thereby causing the feed pipe 703 at the top of the rotating ring 702 and the hopper 704 to rotate together. The weighed raw material is evenly spread in a ring shape inside the melting furnace 1 from the material hole 805 at the top of the furnace cover 6, preventing the raw material from accumulating on one side of the melting furnace 1, thus preventing the raw material from clumping. The evenly spread raw material accelerates the melting speed of the raw material and the uniformity of the mixture of various raw materials. When feeding, the clamping plate 9 at the bottom of the proportioning box 3 and the hopper 704 are engaged, so that the raw material inside the proportioning box 3 falls into the hopper 704. Example 2:

[0021] Please see Figure 1-7This embodiment provides a precise feeding mechanism for zinc alloy proportioning based on embodiment one: a vibrating element 10 is installed between the connecting ring 701 and the feeding pipe 703. The vibrating element 10 includes an assembly rod 101 fixedly connected to the outside of the connecting ring 701. A sleeve post 102 is fixedly connected to one end of the assembly rod 101. A telescopic post 103 is slidably connected inside the sleeve post 102. A spring 104 is fixedly connected between the sleeve post 102 and the telescopic post 103. A stop plate 105 is fixedly connected to the outside of the feeding pipe 703.

[0022] The assembly rods 101 are provided in a plurality of circular arrangement.

[0023] In this embodiment, during the feeding process, as the rotating ring 702 rotates, the abutment 105 on the outside of the feeding pipe 703 continuously impacts the telescopic column 103 inside the sleeve column 102. The vibration generated by the abutment 105 causes the feeding pipe 703 to shake, preventing the raw material inside the feeding pipe 703 from becoming blocked.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Working principle: In the preparation of zinc alloy, zinc blocks are put into the smelting furnace 1 for smelting. At this time, the hopper 704 of the feed pipe 703 and the clamping plate 9 at the bottom of the proportioning box 3 are engaged, connecting the raw material box and the guide pipe 4 at the top of the proportioning box 3. According to the proportioning requirements, different raw materials fall from the external raw material box into the corresponding proportioning tank 501 of the proportioning box 3 through the guide pipe 4. At the same time, the raw materials fall into the weighing hopper 503. The weighing sensor 504 installed between the weighing frame 502 and the weighing hopper 503 monitors the raw materials. Weighing is performed. Once the raw materials reach the required proportions, the external raw material tank stops feeding, and the solenoid valve 505 inside the weighing hopper 503 opens, allowing the raw materials to fall from the weighing hopper 503 into the hopper 704. At this time, the servo motor 802 drives the gear 803 fixed at its output end to rotate inside the cavity connecting plate 801. The rotating gear 803 drives the rotating ring 702 connected to the gear ring 804 to rotate inside the connecting ring 701, thereby driving the feeding pipe 703 at the top of the rotating ring 702. The hopper 704 moves in a ring. At this time, the raw material inside the hopper 704 is spread in a ring inside the smelting furnace 1 to prevent the raw material from accumulating on one side of the smelting furnace 1, thereby preventing the accumulating raw material from clumping together. It also spreads the raw material evenly, improves the uniformity of raw material smelting, shortens the residence time of the metal raw material in the oxidizing environment, reduces the degree of oxidation and burn-off of the raw material, reduces the slag generated after smelting the raw material after oxidation, and speeds up the metal smelting speed. During the rotation of the feed pipe 703, the outer abutment plate 105 and the telescopic column 103 collide. The impact force generated by the collision causes the feed pipe 703 to shake, preventing the raw material from clogging inside the feed pipe 703. After the abutment plate 105 and the telescopic column 103 touch, the telescopic column 103 slides inside the sleeve column 102, while the spring 104 is compressed. When the telescopic column 103 and the abutment plate 105 separate, the spring 104 rebounds, pushing the telescopic column 103 out of the sleeve column 102.
