Description

TECHNICAL FIELD

[0001] The utility model belongs to non-ferrous metal production device technical field, concretely relates to a non-ferrous metal reducing device. BACKGROUND

[0002] In the production process of non-ferrous metals such as magnesium and calcium, an important link is the reduction process. The reduction process specifically refers to: after dolomite and silicon-iron powder are mixed and pressed into balls, a reduction reaction occurs in the high-temperature environment in the reduction tank, high-temperature magnesium and calcium vapor is precipitated, and the vapor crystallizes into crude magnesium and calcium under low temperature in a vacuum environment.

[0003] In the prior art, the reduction tank is welded at one end with a tank bottom and at the other end with a water jacket. The water jacket is a closed annular space formed by an outer cylinder, an inner cylinder and a top flange. By providing inlet and outlet water pipes on the outer cylinder, cooling water is circulated in the closed annular space.

[0004] The inner cylinder of the water jacket contains a crystallizer. Due to the cooling effect of the water jacket circulating water, the temperature in the crystallizer is relatively low. When high-temperature magnesium and calcium vapor drifts into the crystallizer, it is cooled and solidified into crude magnesium and calcium.

[0005] In the above crystallization process, the water jacket and the crystallizer are essential. The crystallizer is a conical cylinder made of steel plate or seamless pipe. Due to the effect of heat radiation, the crystallizer will gradually thin out, and it is a consumable part with high replacement cost. Moreover, the crude magnesium and calcium generated in the crystallizer are dendritic and loose in texture, and the efficiency of magnesium and calcium extraction is low.

[0006] When high-temperature magnesium and calcium vapor drifts into the crystallizer, part of the high-temperature vapor also drifts into the gap between the crystallizer and the water jacket. After crystallization, the crystallizer and the water jacket are bonded together, making it very difficult to pull the crystallizer out of the water jacket, usually requiring a lot of manpower or using special hydraulic equipment. Sometimes, the water jacket needs to be cut off from the reduction tank and then pressed out using a press machine, which is labor-intensive.

[0007] After the crystallizer is taken out of the reduction tank, it is transported to a special magnesium pressing machine to press the crude magnesium and calcium out of the crystallizer. This process is also time-consuming and labor-intensive. UTILITY MODEL CONTENTS

[0008] To solve the above problems, the utility model provides a non-ferrous metal reducing device, which can conveniently take out the crystallized crude magnesium and calcium.

[0009] To solve the above problems, the utility model adopts the following technical scheme:

[0010] A non-ferrous metal reduction device, comprising a reduction tank, an upper condensation adsorption plate and a central pipe, the upper end of the reduction tank is fixed with an upper cone body in communication therewith, and the lower end of the reduction tank is fixed with a lower cone body in communication therewith; the upper cone body is detachably fixedly connected with an upper cover, the lower cone body is detachably fixedly connected with a lower cover, and a closed space is formed between the upper cone body, the reduction tank and the lower cone body by blocking with the upper cover and the lower cover; the central pipe is located in the reduction tank, and a plurality of exhaust holes are formed in the central pipe;

[0011] A vacuum interface in communication with the upper cone body is arranged on the upper cone body, the upper condensation adsorption plate is located in the upper cone body, and the upper condensation adsorption plate has a first cooling cavity; the upper cover is fixedly connected with an upper water inlet pipe and an upper water outlet pipe in communication with the first cooling cavity, and the upper water inlet pipe and the upper water outlet pipe are fixedly connected with the upper condensation adsorption plate.

[0012] The upper condensation adsorption plate is detachably fixedly connected with a suspender.

[0013] The upper end of the suspender is insertedly fixed with the upper condensation adsorption plate, and the lower end of the suspender is conical.

[0014] A lower crystallization cylinder is fixedly connected between the lower cone body and the lower cover, a closed space is formed between the upper cone body, the reduction tank, the lower cone body and the lower crystallization cylinder by blocking with the upper cover and the lower cover, a lower condensation adsorption plate is arranged in the lower crystallization cylinder, the lower condensation adsorption plate has a second cooling cavity, and the lower cover is fixedly connected with a lower water inlet pipe and a lower water outlet pipe in communication with the second cooling cavity; the lower water inlet pipe and the lower water outlet pipe are fixedly connected with the lower condensation adsorption plate.

[0015] A first sealing ring is arranged between the lower crystallization and the lower cover.

[0016] The upper cover is fixedly connected with an ear.

[0017] A second sealing ring is arranged between the upper cover and the upper cone body.

[0018] Compared with the prior art, the non-ferrous metal reduction device has the beneficial effects that:

[0019] In the reduction device, no crystallizer is arranged, but the magnesium-calcium vapor generated is cooled by the upper condensation adsorption plate, so that the crude magnesium and the crude calcium adhere to the upper condensation adsorption plate, and the adhesion between the crude magnesium and the crude calcium and the upper condensation adsorption plate is small, so that the crude magnesium and the crude calcium are easily separated.

[0020] The upper condensation adsorption plate has the first cooling cavity and is located in the upper cone body, so that the cooling range is large, and the crystallization effect is improved. At the same time, the shape of the crystallized crude magnesium and crude calcium is hemispherical, the texture is compact, and the purity is high. The reduction device eliminates the structure of the existing crystallizer, and can realize the crystallization effect without the crystallizer.

[0021] To prevent insufficient adhesion between the upper condensation adsorption plates, which could cause the coarse magnesium and coarse calcium to detach too easily, a hanger is installed to improve adhesion. The hanger is detachably fixed to the upper condensation adsorption plate, and can be removed for separation. Attached Figure Description

Detailed Implementation

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0025] like Figure 1 As shown, a non-ferrous metal reduction device includes a reduction tank 1, an upper condensation adsorption plate 2, and a central tube 3. An upper cone 4, communicating with the upper end of the reduction tank 1, is fixed to the upper end of the tank, and a lower cone 5, communicating with the lower end of the tank, is fixed to the lower end of the tank. An upper cover 6 is detachably and fixedly connected to the upper cone 4, and a lower cover 7 is detachably and fixedly connected to the lower cone 5. The upper cover 6 and lower cover 7 seal the space between the upper cone 4, the reduction tank 1, and the lower cone 5. The central tube 3 is located inside the reduction tank 1 and has several exhaust holes 8. A vacuum interface 9, communicating with the upper cone 4, is provided on the upper cone 4. The aforementioned detachable connections can be achieved using bolts.

[0026] During use, magnesium-calcium pellets are filled between the central tube 3 and the reduction tank 1. Due to the high temperature outside the reduction tank 1, the internal temperature of the reduction tank 1 reaches 12000-1350℃, and the magnesium-calcium pellets undergo a reduction reaction at high temperature to generate magnesium-calcium vapor.

[0027] The upper condensation adsorption plate 2 is located inside the upper cone 4, and the upper condensation adsorption plate 2 has a first cooling chamber 20; an upper water inlet pipe 10 and an upper water outlet pipe 11, which communicate with the first cooling chamber 20, are fixedly connected to the upper cover 6, and the upper water inlet pipe 10 and the upper water outlet pipe 11 are fixedly connected to the upper condensation adsorption plate 2. Cooling water enters the first cooling chamber 20 through the upper water inlet pipe 10 to absorb heat, and the cooled water after absorbing heat is discharged through the upper water outlet pipe 11.

[0028] The generated magnesium-calcium vapor drifts to the upper condensation adsorption plate 2, and is cooled and solidified into crude magnesium and crude calcium under low temperature.

[0029] The upper cover 6 and the lower cover 7 are removed; at the same time, the upper cover 6 is lifted, and the upper cover 6 is lifted together with the upper water inlet pipe 10, the upper water outlet pipe 11 and the upper condensation adsorption plate 2 to a designated position. The crude magnesium and the crude calcium can be separated from the upper condensation adsorption plate 2 by simply knocking the upper condensation adsorption plate 2.

[0030] Further, the adhesion between the upper condensation adsorption plate 2 and the crude magnesium and the crude calcium is relatively small, and the crude magnesium and the crude calcium may be separated from the upper condensation adsorption plate 2 due to accidental impact during production. Therefore, the lifting rod 12 is detachably fixed to the upper condensation adsorption plate 2, and the adhesion is increased by the lifting rod 12, that is, the crude magnesium and the crude calcium are attached to the lifting rod 12 and the upper condensation adsorption plate 2. When separation is needed, the lifting rod 12 is separated from the upper condensation adsorption plate 2, and then the upper condensation adsorption plate 2 is knocked.

[0031] Further, the upper end of the lifting rod 12 is inserted and fixed to the upper condensation adsorption plate 2, and the lower end of the lifting rod 12 is conical. The conical structure can increase the adhesion of the crude magnesium and the crude calcium. Specifically, the upper end of the lifting rod 12 penetrates through the upper condensation adsorption plate 2 and is connected with a split pin. When the lifting rod 12 needs to be separated, the split pin is pulled out.

[0032] Further, the high-temperature magnesium-calcium vapor mainly condenses in the upper part of the closed space, that is, the crude magnesium and the crude calcium mainly crystallize on the upper condensation adsorption plate 2. However, during actual operation, part of the high-temperature magnesium-calcium vapor is still below the closed space.

[0033] Therefore, the lower crystallization cylinder 13 is fixedly connected between the lower cone 5 and the lower cover 7, that is, the upper end of the lower crystallization cylinder 13 is fixedly connected to the lower part of the lower cone 5 and communicates with the lower cone 5, and the lower cover 7 is fixedly connected to the lower end of the lower crystallization cylinder 13. The upper cover 6 and the lower cover 7 are sealed to form a closed space between the upper cone 4, the reduction tank 1, the lower cone 5 and the lower crystallization cylinder 13.

[0034] The lower condensation adsorption plate 14 is arranged in the lower crystallization cylinder 13, and the lower condensation adsorption plate 14 has a second cooling cavity 140. The lower cover 7 is fixedly connected with a lower water inlet pipe 15 and a lower water outlet pipe 16 which communicate with the second cooling cavity 140. The lower water inlet pipe 15 and the lower water outlet pipe 16 are fixedly connected with the lower condensation adsorption plate 14. Similarly, the cooling water enters the second cooling cavity 140 through the lower water inlet pipe 15, and the cooling water in the second cooling cavity 140 absorbs heat and is discharged through the lower water outlet pipe 16.

[0035] The high-temperature magnesium-calcium vapor at the lower condensation adsorption plate 14 is cooled and solidified on the lower condensation adsorption plate 14. The crude magnesium and the crude calcium solidified on the lower condensation adsorption plate 14 can be taken out by removing the lower cover 7.

[0036] Further, in order to improve the sealing effect, a first sealing ring 17 is arranged between the lower cone 7 and the lower cover 6; a second sealing ring 19 is arranged between the upper cover 6 and the upper cone 4.

[0037] Further, in order to facilitate lifting, a lifting lug 18 is fixedly connected to the upper cover 6.

[0038] The above only describes the preferred embodiments of the present application in detail, but the present application is not limited to the above embodiments.
