Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic aluminum equipment, and in particular relates to a take-out device for an aluminum oxide feeder cone. Background Art

[0002] In the process of electrolytic aluminum operation, the feeder is a common device for controlling the feeding. The feeder is installed in the upper material box and is used to discharge the alumina in the upper material box to the lower material box to realize the feeding. Among them, the feeder includes a cylinder and a cone installed at the bottom of the cylinder. The cylinder is opened and closed by the cone, so as to feed or stop feeding. The cone and the bottom of the cylinder are usually connected by screws. When the screws are loosened, the cone and the bottom of the cylinder are relatively separated to form an opening to realize feeding. When the screws are tightened, the cone and the bottom of the cylinder are closed to stop feeding. During use, when the screws are loosened, it is easy for the cone to completely detach from the cylinder and fall into the lower material box. At this time, it is necessary to remove the cone from the lower material box in time to avoid affecting the subsequent operation process. However, the lower material box is in a closed state and has only a narrow opening. At the same time, it is in a high temperature, strong magnetic, and strong vibration working state, so it is not easy to remove the fallen cone. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Before describing the various embodiments of the present application in detail, the technical concept of the present application is first briefly described: the cone of the current feeder is prone to falling into the lower material box during use, and it is difficult to remove the cone due to the structure of the lower material box, the environment and other factors. To this end, the present application provides an extractor for the cone of an alumina feeder, and a storage hole is provided on the side wall of a removal rod, and a rotatable block is installed in the storage hole. The block can be received in the storage hole and can be extended out of the storage hole. During the process of the removal rod passing through the cone, the block retracts into the storage hole. After passing through, the block extends and is supported on the bottom of the cone. At this time, the removal rod is lifted to remove the cone. The specific principle of the extractor for the cone of an alumina feeder of the present application is described below in combination with more embodiments.

[0024] Specifically, Figure 1 and Figure 2 As shown, the extractor for the cone of the alumina feeder of the first embodiment includes an extractor rod 10 and a stopper 20. A receiving hole 11 is provided on the side wall of the extractor rod 10. The stopper 20 is rotatably mounted on the receiving hole 11. The extractor rod 10 is used to pass through the cone 30 to be removed. When the extractor rod 10 is in a vertical posture and passes through the cone 30 to be removed, a part of the stopper 20 extends out of the receiving hole 11 to support the bottom of the cone 30 to be removed. Among them, a through hole 31 is provided at the center of the cone 30 to be removed. The inner diameter of the through hole 31 is slightly larger than the diameter or width of the extractor rod 10, so that the extractor rod 10 can pass through the cone 30 to be removed. When a part of the stopper 20 extends out of the receiving hole 11, the through hole 31 cannot allow the stopper 20 to pass, which can ensure that the stopper 20 is stably supported at the bottom of the cone 30 to be removed, so that the cone 30 to be removed can be removed smoothly.

[0025] Exemplarily, the rotation axis direction of the stopper 20 is perpendicular to the length direction of the removal rod 10, that is, when the removal rod 10 is in a vertical state, the stopper 20 can rotate in the vertical direction, so that the stopper 20 can be retracted into the storage hole 11 or extended out of the storage hole 11. In one embodiment, a pin 22 is provided inside the storage hole 11, and the stopper 20 is rotatably connected to the pin 22, and the pin 22 is provided along a direction perpendicular to the length of the removal rod 10, so as to realize the rotation of the stopper 20. In another embodiment, a protrusion is provided on the surface of the stopper 20, and the protrusion is rotatably connected to the inner wall of the storage hole 11.

[0026] Furthermore, the stopper 20 is a triangular flat plate, and the rotation axis direction of the stopper 20 is parallel to the thickness direction of the stopper 20, that is, when the removal rod 10 is in a vertical state, the stopper 20 is arranged along the vertical direction, which is beneficial to improving the rotation flexibility of the stopper 20 on the one hand, and on the other hand, it is beneficial to reduce the opening size of the storage hole 11. The width of the storage hole 11 can be slightly larger than the thickness of the stopper 20.

[0027] In one embodiment, when the removal rod 10 is in a vertical position and passes through the cone 30 to be removed, two corners of the stopper 20 extend out of the receiving hole 11 and the other corner is located inside the receiving hole 11. For example, the right angle and one acute angle of the stopper 20 extend out of the receiving hole 11, the other acute angle is located inside the receiving hole 11, and the bottom of the stopper 20 abuts against the lower edge 11a of the receiving hole 11, and the top of the stopper 20 is supported on the bottom of the cone 30 to be removed.

[0028] In another embodiment, if Figure 3 As shown, when the removal rod 10 is passing through the cone 30 to be removed, two corners of the stopper 20 are located inside the receiving hole 11, and the other corner of the stopper 20 is located outside the receiving hole 11 and abuts against the upper edge 11b of the receiving hole 11. Exemplarily, the right angle and one acute angle of the stopper 20 are located inside the receiving hole 11, and the other acute angle is located outside the receiving hole 11. On the one hand, most of the stopper 20 can be located outside the receiving hole 11 to ensure that the removal rod 10 can smoothly pass through the through hole 31 of the cone 30 to be removed. On the other hand, when the stopper 20 is retracted into the receiving hole 11 and cannot be extended again in a natural state, the bottom of the cone 30 to be removed can cooperate with the other acute angle outside the receiving hole 11 to push the stopper 20 to rotate, so that most of the stopper 20 extends out of the receiving hole 11, so as to achieve the bottom support of the cone 30 to be removed. Among them, when the removal rod 10 is in a vertical posture, the upper edge 11b mentioned here is located above the lower edge 11a.

[0029] Furthermore, the other corner of the block 20 has a recessed portion 21, which abuts against the upper edge 11b of the storage hole. On the one hand, one corner of the block 20 can be located outside the storage hole 11, so that more parts of the block 20 can be stored in the storage hole 11, avoiding any influence during the process of the removal rod 10 penetrating the cone 30 to be removed.

[0030] Furthermore, the storage hole 11 is a strip-shaped hole, which extends along the length direction of the removal rod 10 and passes through the side walls on both sides of the removal rod 10. In this way, the block 20 can be set to rotate in and out from one side of the storage hole 11 as needed, or two blocks 20 can be set, and the two blocks 20 rotate in and out from both sides of the storage hole 11 respectively.

[0031] Furthermore, a handle 12 is installed at one end of the removal rod 10 away from the stopper 20 , and the handle 12 is convenient for an operator to lift the removal rod 10 .

[0032] Exemplarily, the removal rod 10 includes a solid rod 10a located at the top and a hollow rod 10b located at the bottom, the solid rod 10a is fixedly connected to the hollow rod 10b, the receiving hole 11 is opened on the side wall of the hollow rod 10b, and the receiving hole 11 is connected to the inside of the hollow rod 10b. The solid rod 10a and the hollow rod 10b are welded to each other, the length of the solid rod 10a is greater than the length of the hollow rod 10b, and the diameter of the hollow rod 10b is equal to the diameter of the solid rod 10a. On the one hand, the main body of the removal rod 10 adopts the solid rod 10a to enhance the strength of the removal rod 10, and on the other hand, the hollow rod 10b can be used to more easily open the receiving hole 11 and better accommodate the stopper 20.

[0033] Exemplarily, the solid rod 10a is a white steel bar with a size of φ12mm*2.3m, the hollow rod 10b is a white steel pipe with a size of φ12mm*100mm, and the stopper 20 is a white steel plate with a thickness of 5mm.

[0034] Of course, in other embodiments, such as Figure 4 As shown, the taking-out rod 10 may also be a solid rod as a whole, and the receiving hole 11 is opened in the solid rod, and the receiving hole 11 passes through the side walls on both sides of the solid rod.

[0035] The extractor for the cone of the alumina feeder provided in the first embodiment can conveniently and quickly remove the cone that has fallen into the lower material box, and the extractor can be suitable for the high temperature and high magnetic environment of the lower material box.

[0036] The specific implementation methods of the present invention are described in detail above. Although some embodiments have been shown and described, those skilled in the art should understand that these embodiments can be modified and improved without departing from the principle and spirit of the present invention whose scope is defined by the claims and their equivalents. These modifications and improvements should also be within the scope of protection of the present invention.
