Description

Technical Field

[0001] The utility model relates to the technical field of aluminum smelting engineering, in particular to a material guiding device and a pre-baked anode production line. Background Art

[0002] The production of pre-baked anodes (also known as anode carbon blocks) is one of the important processes in modern aluminum electrolysis. The quality of pre-baked anodes will directly affect the current efficiency and energy consumption of aluminum electrolysis production. After baking, the anode has a stable geometric shape, so it is also called a pre-baked anode carbon block, and is habitually called a carbon anode for aluminum electrolysis.

[0003] One of the main core processes in the production of pre-baked anodes is forming, which refers to the process in which the kneaded carbonaceous paste undergoes plastic deformation under the external force applied by the forming equipment and finally becomes a green body (or called a green product) with a certain shape, size, density and strength. In order to ensure that the green product has good density and strength, it is necessary to improve the kneading quality of the carbonaceous paste.

[0004] The influencing factors of the kneading quality of carbonaceous paste are mainly kneading power, kneading time and kneading temperature. The kneading temperature is jointly determined by the dry material temperature, the asphalt temperature and the temperature of the kneading equipment itself.

[0005] The existing pre-baked anode production line includes a feeding device and a heating device arranged below the feeding device. The materials of the feeding device directly enter the heating device, and it is difficult to ensure the uniform heating of the dry materials in the heating device, which is likely to lead to a decline in the kneading quality of the carbonaceous paste. Therefore, it is particularly important to achieve uniform heating of the dry materials in the heating device. Summary of the Utility Model

One end of the outer shaft sleeve is inserted into the through hole, and the other end of the outer shaft sleeve extends out of the outside of the material box and the inner shaft sleeve is installed inside the extending end. The end cover is used to fix the inner shaft sleeve in the outer shaft sleeve; the limiting member is sleeved on one end of the rotating shaft, and the limiting member contacts and limits the end cover in an axially displaceable manner. The material guiding plate is fixed on the rotating shaft and is located inside the material box.

For the convenience of narration, words such as "upper", "lower", "left", and "right" in the following text only indicate the same direction as the upper, lower, left, and right directions of the drawings themselves, and do not limit the structure.

[0026] As Figure 1 、 Figure 2 、 Figure 3 shown, a material guiding device 1 provided in this embodiment includes a material box 11, a material guiding component 12, a limiting component 13, and a bolt 14.

[0027] The material box 11 is a rectangular cylinder, with both ends being through and respectively forming a feeding port 111 and a discharging port 112, and the feeding port 111 is located at the upper end.

[0028] In a specific embodiment, in order to facilitate the internal inspection of the material box 11 and the installation of the material guiding component 12, a rectangular opening through which the material guiding plate 125 can enter and exit is opened on one side wall of the material box 11, and an inspection door 115 is installed on the rectangular opening by screws, and one of the through holes 114 is provided on the inspection door 115.

[0030] The length of the rotating shaft 121 is longer than that of the material box 11, so that both ends of the rotating shaft 121 extend out of the outside of the material box 11. Outer shaft sleeves 123 and inner shaft sleeves 122 are sleeved on both ends of the rotating shaft 121. As Figure 3 shown, one end of the outer shaft sleeve 123 is inserted into the through hole 114, and the other end of the outer shaft sleeve 123 extends out of the outside of the material box 11 and the inner shaft sleeve 122 is installed inside the extending end. The inner shaft sleeve 122 can be purchased as strip-shaped asbestos, which is filled in the inner hole at one end of the outer shaft sleeve 123, and the rotating shaft 121 passes through the asbestos.

[0031] The end cover 124 is used to fix the inner shaft sleeve 122 in the outer shaft sleeve 123, and the end cover 124 is fixed to the outer shaft sleeve 123 by bolts 14.

[0032] A plurality of the jacks 126 are arranged in a circle on the end cover 124 on one side of the material box 11, and angle scale lines are arranged beside the jacks 126. The deflector 125 is fixed on the rotating shaft 121 and is located inside the material box 11. Rotating the rotating shaft 121 can switch the deflector 125 in the left-right direction of the feed port 111.

[0033] In another embodiment, as Figure 3 shown, the jacks 126 can also be arranged on the outer shaft sleeve 123, that is, a flange plate is arranged at the extending end of the outer shaft sleeve 123, a plurality of jacks 126 are arranged in a circle on the flange plate, and the end cover 124 is then attached to the end face of the flange plate and fixed by bolts 14.

One end of the limiting plate 131 is installed on the rotating shaft 121, and the limiting rod 132 is arranged at the other end. The limiting plate 131 is located outside the end cover 124. The limiting rod 132 can be selected as a bolt or a pin shaft, and its axis extends axially to be inserted into one of the jacks 126 to limit the angular position of the deflector 125.

The discharge port 112, the material cylinder 3 and the heating device 4 are in communication.

[0038] As Figure 5 shown, when the first spiral shaft discharges materials, there is more material on the left side than on the right side. Then, adjust the rotating shaft 121 to make the material guiding plate 125 deflect to the left side, so that the part of the material fed on the left side is guided to the right side to balance the material feeding on both the left and right sides. Similarly, when there is more material on the right side than on the left side when the first spiral shaft discharges materials, then adjust the rotating shaft 121 to make the material guiding plate 125 deflect to the right side, so that the part of the material fed on the right side is guided to the left side. The fine adjustment angle of the material guiding plate 125 is 15 degrees.

[0039] In addition, observation holes are provided on both sides of the housing of the heating device 4.
