Description

Technical Field

[0001] This utility model relates to the field of zinc alloy preparation technology, specifically to a melting furnace for zinc alloy preparation. Background Technology

[0002] The preparation of zinc alloys requires the production of specific alloy grades, calculation of the amount of various alloy components to be added, reasonable matching of various raw materials, and the addition of the prepared raw materials into the melting furnace according to the process requirements. The melting furnace is one of the most important pieces of equipment in the preparation of zinc alloys.

[0003] For example, utility model patent CN207831919U discloses a new type of high-efficiency and energy-saving aluminum melting furnace, which generally includes an inner furnace body and an outer furnace body. The inner furnace body is embedded inside the outer furnace body, and multiple shock-absorbing springs are evenly fixed between the outer furnace body and the inner furnace body. One end of the support rod is fixedly connected to the electric heating frame set inside the inner furnace body. Three stirring rods are symmetrically arranged on the two side walls inside the inner furnace body. Multiple stirring blades are equidistantly fixed on the outer wall of the stirring rods, and one end of the stirring rod is connected to the motor fixed on the outer wall of the outer furnace body through a bushing. In use, baffles are symmetrically fitted at the top inside the inner furnace body, and multiple small holes are evenly opened on the outer wall of the baffles. This allows for the quantitative feeding of materials by pulling the baffles. Water cooling pipes are installed in the interlayer of the inner wall of the outer furnace body to accelerate the heat dissipation rate of the entire melting furnace after use.

[0004] In the aforementioned existing technical solutions, since the melting furnace does not wait for the furnace to cool down after melting once, a second melting process is not carried out. Because the opening faces upward, the feed port will be open for a long time while the raw material is injected into the melting furnace through the upward-facing opening. This will cause a large amount of heat to dissipate from the feed port, which will easily reduce the melting efficiency of the second melting process and has low practicality. Utility Model Content

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by this utility model is that when feeding, the feed port will be open for a long time, which will cause a large amount of heat to be dissipated from the feed port.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a melting furnace for preparing zinc alloys, comprising:

[0007] The melting furnace body has a feeding port at its upper end;

[0008] The transfer box has an opening at its upper end and its lower end abuts against the melting furnace. The lower end of the transfer box has two material discharge ports. The transfer box is rotatably mounted on the upper end of the melting furnace body, and the feeding port is located on the travel of the two material discharge ports.

[0009] A partition plate is fixedly installed inside the transfer box to separate the transfer box; and the two discharge ports are located on both sides of the partition plate.

[0010] A cover plate, fixedly installed on the melting furnace body, and the partition plate abutting against the upper opening of the transfer box to close the transfer box; the cover plate has a feeding port, and the feeding port and the material inlet are respectively located on both sides of the partition plate; and

[0011] A drive mechanism drives the transfer box to rotate.

[0012] Preferably, it also includes a feeding funnel, which is connected to the feeding port.

[0013] Preferably, the feeding funnel is connected to the feeding port via an extension pipe.

[0014] Preferably, a circular groove is provided on the upper end face of the melting furnace body, and the circular groove is recessed into the melting furnace body; the transfer box is rotatably installed in the circular groove.

[0015] Preferably, the driving mechanism includes: a gear ring, a gear, and a motor; the gear ring is coaxially fixed with the transfer box, the gear is rotatably mounted on the cover plate, and the gear meshes with the gear ring; the motor drives the gear to rotate.

[0016] Preferably, it also includes a protective shell, which is mounted on the cover plate to cover the gear.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] 1. In this utility model, the zinc alloy material is fed into the transfer box through the feeding port on the cover plate, so that the zinc alloy material is located on one side of the partition plate. At this time, the discharge port is abutted and closed with the upper end face of the melting furnace body. After the transfer box on one side of the partition plate is filled with enough zinc alloy material, the drive mechanism is controlled to move. The drive mechanism drives the transfer box to rotate, and the transfer box drives the discharge port to rotate, so that the discharge port is connected with the feeding port. Under the action of gravity, the zinc alloy material in the transfer box is added into the melting furnace body through the discharge port and the feeding port. In this way, the addition of zinc alloy material can be completed. Under the action of the partition plate, the heat in the melting furnace body will be blocked, thereby reducing the heat loss in the melting furnace body when adding zinc alloy material. The transfer box on the other side of the partition plate is connected to the feeding port on the cover plate, so that zinc alloy material can be added into the transfer box on the other side of the partition plate.

[0019] 2. In this utility model, the partition plate divides the transfer box into two cavities. After one cavity is filled with zinc alloy material, the transfer box can be rotated. At this time, the extension tube allows zinc alloy material to be continuously added while the transfer box is rotating. Excess zinc alloy material can be stored in the extension tube. After the other cavity is connected to the extension tube, it can fall into the other cavity by gravity, thus eliminating the need to stop the feeding operation and ensuring continuous feeding.

[0020] 3. In this utility model, the circular groove increases the contact area between the transfer box and the melting furnace body, allowing the zinc alloy material in the transfer box to absorb some of the heat from the melting furnace body and preheat the zinc alloy material to be added, thereby improving the melting efficiency of the zinc alloy material entering the melting furnace body.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] See Figures 1-3The present invention provides an embodiment of a melting furnace for preparing zinc alloy, characterized in that it comprises: a melting furnace body 1, a transfer box 2, a partition plate 3, a cover plate 4, and a driving mechanism 5. The upper end of the melting furnace body 1 has a feeding port 11; the upper end of the transfer box 2 is open, and the lower end of the transfer box 2 abuts against the melting furnace, with two discharge ports 21 at the lower end; the transfer box 2 is rotatably mounted on the upper end of the melting furnace body 1, and the feeding port 11 is located on the stroke of the two discharge ports 21; the partition plate 3 is fixedly mounted inside the transfer box 2 to separate the transfer box 2; and the two discharge ports 21 are located on both sides of the partition plate 3; the cover plate 4 is fixedly mounted on the melting furnace body 1, and the partition plate 3 abuts against the upper opening of the transfer box 2 to close the transfer box 2; the cover plate 4 has a feeding port 41, and the feeding port 41 and the feeding port 11 are respectively located on both sides of the partition plate 3; the driving mechanism 5 drives the transfer box 2 to rotate.

[0028] In practice, the zinc alloy material is fed into the transfer box 2 through the feeding port 41 on the cover plate 4, so that the zinc alloy material is located on one side of the partition plate 3. At this time, the discharge port 21 is sealed by contact with the upper end face of the melting furnace body 1. After the transfer box 2 on one side of the partition plate 3 is filled with enough zinc alloy material, the drive mechanism 5 is controlled to move. The drive mechanism 5 drives the transfer box 2 to rotate, and the transfer box 2 drives the discharge port 21 to rotate, so that the discharge port 21 is connected to the feeding port 11. Under the action of gravity, the zinc alloy material in the transfer box 2 is added into the melting furnace body 1 through the discharge port 21 and the feeding port 11. In this way, the addition of zinc alloy material can be completed. Under the action of the partition plate 3, the heat in the melting furnace body 1 will be blocked, thereby reducing the heat loss in the melting furnace body 1 when adding zinc alloy material. The transfer box 2 on the other side of the partition plate 3 is connected to the feeding port 41 on the cover plate 4, so that zinc alloy material can be added into the transfer box 2 on the other side of the partition plate 3.

[0029] See Figures 1-3 In other embodiments, a feeding funnel 6 is also included, which is connected to the feeding port 41. The feeding funnel 6 facilitates the addition of zinc alloy material. Furthermore, the feeding funnel 6 is connected to the feeding port 41 via an extension pipe 7. Specifically, the partition plate 3 divides the transfer box 2 into two chambers. After one chamber is filled with zinc alloy material, the transfer box 2 can be rotated. At this time, the extension pipe 7 allows for continuous addition of zinc alloy material while the transfer box 2 is rotating. Excess zinc alloy material can be stored in the extension pipe 7. After the other chamber is connected to the extension pipe 7, it can fall into the other chamber by gravity, thus ensuring continuous feeding without stopping the feeding operation.

[0030] See Figures 1-3In other embodiments, a circular groove 12 is provided on the upper end face of the melting furnace body 1, and the circular groove 12 is recessed into the melting furnace body 1; the transfer box 2 is rotatably installed in the circular groove 12. In specific implementation, by setting the circular groove 12, the contact area between the transfer box 2 and the melting furnace body 1 can be increased, so that the zinc alloy material in the transfer box 2 can absorb part of the heat in the melting furnace body 1, preheating the zinc alloy material to be added, thereby improving the melting efficiency of the zinc alloy material entering the melting furnace body 1.

[0031] See Figures 1-3 In another embodiment, the drive mechanism 5 includes a gear ring 51, a gear 52, and a motor 53. The gear ring 51 is coaxially fixed to the transfer box 2, and the gear 52 is rotatably mounted on the cover plate 4, meshing with the gear ring 51. The motor 53 drives the gear 52 to rotate. In specific implementation, when the motor 53 operates, it drives the gear 52 to rotate, which in turn drives the gear ring 51 to rotate, thus rotating the transfer box 2. Furthermore, a protective shell 54 is included, which is mounted on the cover plate to cover the gear 52; the protective shell 54 effectively protects the gear 52.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
