Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a charging hopper used for a nonferrous smelting furnace. Background Art

[0002] In the oxygen-enriched smelting process of non-ferrous metals, raw materials, coke, auxiliary materials, etc. need to be continuously added from the top of the smelting furnace in a certain proportion. The common practice in the industry is to add materials into the hopper in a certain order and proportion, and then transport the hopper to the top of the furnace through the conveying system, and then the discharge door at the bottom of the hopper is opened by a hydraulic device or a motor to allow the materials to fall into the smelting furnace.

[0003] Due to the harsh high temperature environment on the furnace top, hydraulic device oil leakage or electrical components burning often occur, which may even affect the smelting efficiency and metal recovery rate in serious cases. Utility Model Content

[0004] Purpose of the utility model: The utility model proposes a charging hopper for a non-ferrous smelting furnace, which can automatically open a charging door by utilizing the gravity characteristics of the material, does not require human participation in the control throughout the process, and is stable and reliable.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A charging hopper for a nonferrous smelting furnace comprises a hopper body, a first discharge door and a second discharge door are movably provided at the bottom of the hopper body, and a first slot group and a second slot group are symmetrically provided on the left and right sides of the hopper body;

[0007] A first lifting beam is slidably mounted in the first slot group, a first connecting rod is disposed between the first discharge door and the first lifting beam, one end of the first connecting rod is hinged to the middle of the first lifting beam, and the other end is hinged to the left end of the first discharge door;

[0008] A second connecting rod is provided between the second discharge door and the first lifting beam, one end of the second connecting rod is hinged to the middle part of the first lifting beam, and the other end of the second connecting rod is hinged to the left end of the second discharge door;

[0009] A second lifting beam is provided in the second slot group, and a third connecting rod is provided between the first discharge door and the second lifting beam. One end of the third connecting rod is hinged to the middle of the enemy lifting beam, and the other end is hinged to the right end of the first discharge door.

[0010] A fourth connecting rod is provided between the second discharge door and the second lifting beam, one end of the fourth connecting rod is hinged to the middle part of the second lifting beam, and the other end thereof is hinged to the right end of the second discharge door.

[0011] As an improvement: a plurality of legs are symmetrically arranged below the hopper body.

[0012] As an improvement: the first discharge door is hinged to the bottom of the hopper body through a plurality of first L-shaped connecting plates.

[0013] As an improvement: the second discharge door is hinged to the bottom of the hopper body through a plurality of second L-shaped connecting plates.

[0014] As an improvement: first anti-tilt wheels are provided at both ends of the first lifting beam, and second anti-tilt wheels are provided at both ends of the second lifting beam.

[0015] In summary, the utility model has the following beneficial effects:

[0016] 1. When materials need to be loaded, the hopper is placed on the ground or on an electric flat car. Since the bottom discharge door and the legs are stressed at the same time, the materials will not leak from the bottom. After the hopper is lifted and translated, it is placed on the charging station on the top of the furnace. At this time, the legs at the bottom of the hopper body are stressed. At the same time, since the charging port of the charging station is an open structure, the bottom discharge door is not constrained. Under the action of gravity, the material will automatically open the discharge port and enter the smelting furnace from the bottom. Through the above operation, the gravity characteristics of the material can be used to automatically open the discharge door. No human control is required throughout the process, and it is stable and reliable.

[0017] 2. When the material in the hopper body is loaded, the lifting device drives the two lifting beams to move upward. Due to the presence of the anti-tilt wheel, the height deviation of the lifting device will not cause the bottom discharge door to be unable to be completely closed and cause leakage. In the process of adding materials to the furnace, due to the presence of the anti-tilt wheel, the lifting beam will not tilt due to the opening speed of the bottom discharge door, which will affect the hopper body and prevent it from being lifted up by the lifting device again and returning.

DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Please refer to Figure 1-Figure 3 A charging hopper for a nonferrous smelting furnace comprises a hopper body 1, a first discharge door 2 and a second discharge door 3 are movably provided at the bottom of the hopper body 1, and a first slot group 4 and a second slot group 5 are symmetrically provided on the left and right sides of the hopper body 1;

[0025] A first lifting beam 6 is slidably mounted in the first slot group 4, and a first connecting rod 8 is disposed between the first discharge door 2 and the first lifting beam 6. One end of the first connecting rod 8 is hinged to the middle of the first lifting beam 6, and the other end is hinged to the left end of the first discharge door 2.

[0026] A second connecting rod 9 is provided between the second discharge door 3 and the first lifting beam 6, one end of the second connecting rod 9 is hinged to the middle of the first lifting beam 6, and the other end is hinged to the left end of the second discharge door 3;

[0027] A second lifting beam 7 is slidably mounted in the second slot group 5, and a third connecting rod 10 is disposed between the first discharge door 2 and the second lifting beam 7. One end of the third connecting rod 10 is hinged to the middle of the enemy lifting beam, and the other end is hinged to the right end of the first discharge door 2.

[0028] A fourth connecting rod 11 is provided between the second discharge door 3 and the second lifting beam 7, one end of the fourth connecting rod 11 is hinged to the middle of the second lifting beam 7, and the other end is hinged to the right end of the second discharge door 3. A plurality of legs 12 are symmetrically provided below the hopper body 1. In this embodiment, when materials need to be loaded, the hopper is placed on the ground or on an electric flat car. Since the bottom discharge door and the legs 12 are stressed at the same time, the materials will not leak from the bottom. After the hopper is lifted and translated, the hopper is placed on the top charging station of the furnace. At this time, the legs 12 at the bottom of the hopper body 1 are stressed. At the same time, since the feeding port of the charging station is an open structure, the bottom discharge door is not constrained. Under the action of gravity, the material automatically opens the discharge port, thereby entering the smelting furnace from the bottom. Through the above operation, the gravity characteristics of the material can be used to automatically open the discharge door, and no human participation in the whole process is required, and it is stable and reliable.

[0029] The first discharge door 2 is hinged to the bottom of the hopper body 1 through a plurality of first L-shaped connecting plates 13. The second discharge door 3 is hinged to the bottom of the hopper body 1 through a plurality of second L-shaped connecting plates 14.

[0030] First anti-tilt wheels 15 are provided at both ends of the first lifting beam 6, and second anti-tilt wheels 16 are provided at both ends of the second lifting beam 7. In this embodiment, the two first anti-tilt wheels 15 can limit the position of the first lifting beam 6, and the two second anti-tilt wheels 16 can limit the position of the second lifting beam 7. Therefore, when the material in the hopper body 1 is loaded, the lifting device 17 drives the two lifting beams to move upward. Due to the presence of the anti-tilt wheels, the height deviation of the lifting device 17 will not cause the bottom discharge door to be unable to be completely closed and cause material leakage. In addition, in the process of adding materials to the furnace, due to the presence of the anti-tilt wheels, the lifting beam will not tilt due to the opening speed of the two bottom discharge doors, thereby affecting the hopper body. Can not be lifted up by the lifting device again and cannot return.

[0031] In this embodiment, the lifting device 17, the electric flat car, etc. are all existing technologies.

[0032] Working principle: When materials need to be loaded, the hopper body 1 is placed on the ground or on an electric flat car. Since the first discharge door 2, the second discharge door 3 and the legs 12 at the bottom are stressed at the same time, the materials will not leak from the bottom. When the hopper body 1 placed on the electric flat car is transported to the lifting station, the lifting device 17 will drive the two lifting beams to rise. Since the two lifting beams are connected to the two discharge doors at the bottom through corresponding connecting rods, the gravity of the materials will not open the discharge doors. After the hopper body 1 is lifted and translated, the hopper body is placed on the furnace top charging station. At this time, the legs 12 are stressed, and since the charging port of the charging station is an open structure, the two discharge doors are not constrained. Under the action of gravity, the materials automatically open the two discharge doors, thereby entering the smelting furnace from the bottom.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
