Description

Technical Field

[0001] The utility model relates to the technical field of material pipe blanking buffer equipment, and more specifically, to a ladle feeder for aluminum electrolysis. Background Technique

[0002] When the ladle feeding device adds alumina powder or crushed material to the electrolytic cell during the production of electrolytic aluminum, the material is transported from the upper bunker of the ladle to the electrolytic cell through the feeding pipe. At present, the feeder in the factory uses a steel pipe vertically arranged in the vertical direction for material transportation. During blanking, due to excessive crushing of some materials and small particle size, the vertical transportation method is likely to cause some materials to be lifted and scattered and not fall to the correct position in the electrolytic cell, increasing the manual labor intensity, polluting the environment, and increasing production costs. Moreover, the materials moving vertically in the feeder usually fall directly from one end of the material pipe inlet to the other end of the material pipe outlet without any obstruction. After the material is output from the outlet, its gravitational potential energy will be converted into kinetic energy and there is a high probability of injuring the blanking equipment, posing a great safety hazard.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 as shown.

[0025] The present utility model provides a gantry crane feeder for aluminum electrolysis, such as Figure 1 , Figure 2As shown in the figure, the utility model provides a gantry crane feeder for aluminum electrolysis, which includes a first pipeline 1, an auxiliary pipeline 2 and a second pipeline 3 that are connected to the feeding bin of the gantry crane. The first pipeline 1, the auxiliary pipeline 2 and the second pipeline 3 are connected in sequence. A fixing component for fixing the auxiliary pipeline 2 is provided directly between the first pipeline 1 and the second pipeline 3. The second pipeline 3 is inclined relative to the auxiliary pipeline 2, and a flexible feeding pipeline 4 is provided at the free end of the second pipeline 3. The main problem solved by the utility model is that when the material enters the electrolytic cell in the prior art, its impact force is relatively large, which is likely to cause damage to the objects in the electrolytic cell, and there is also a problem that the material often accumulates at a fixed position during the later stage of guided transmission, which is not conducive to the later electrolysis operation of the material. To solve the above problems, when the operator uses the gantry crane to feed materials such as alumina or broken materials into the electrolytic cell, the gantry crane operator uses the remote control of the gantry crane to move the feeding pipeline 4 into the electrolytic cell, and presses the feeding button. The material is guided and conveyed to the designated position of the electrolytic cell through the first pipeline 1, the auxiliary pipeline 2, the second pipeline 3 and the auxiliary pipeline 2. When the material comes from the gantry crane bin to the end of the feeding pipe, the contact area between the material and the inner wall of the bending part of the second pipeline 3 increases, so that the friction force between the materials also increases accordingly, thereby reducing the impact force of the material and playing a certain buffering effect on the feeding and transmission of the material; and a flexible feeding pipeline 4 is sleeved at the free end of the second pipeline 3. After the material is buffered by the inclined second pipeline 3, it then enters the flexible feeding pipeline 4. At this time, the feeding pipeline 4 made of cotton and linen material and in the shape of a cloth bag uses its softness to buffer the material with a large impact force, reduce the initial speed when the material descends, and avoid damage to the side wall in the electrolytic cell caused by the too large initial speed of the material, which affects the service life of the electrolytic cell.

[0026] In some technical solutions of the utility model, the axis of the auxiliary pipeline 2 intersects with the axis of the second pipeline 3 at an obtuse angle. The set second pipeline 3 can be bent into 45 degrees by machining the entire steel pipeline, so as to change the movement direction of the material when it moves to the second pipeline 3, and use the bending part of the second pipeline 3 to weaken the downward impact force of the material.

[0027] In some technical solutions of the utility model, the fixing component includes a plurality of steel ropes 5. A connecting disc 11 integrally formed with the first pipeline 1 by welding is provided at the end of the first pipeline 1. Connectors 10 integrally formed with the auxiliary pipeline 2 by welding are provided at both ends of the auxiliary pipeline 2. The plurality of steel ropes 5 are detachably arranged between the two connectors 10 through hanging ears. The connecting disc 11 is detachably connected to one of the connectors 10 by bolts, and the other connector 10 is connected to the second pipeline 3 by bolts. In this way, the auxiliary pipeline 2 and the second pipeline 3 can be fixed on the first pipeline 1.

[0028] In some technical solutions of the utility model, a plurality of corrugated layers are arranged on the inner wall of the auxiliary pipe 2 along its extension direction. The auxiliary pipe 2 is a corrugated pipe, which includes a steel ring and a high temperature resistant rubber skin. The steel ring and the high temperature resistant rubber skin are combined to form a corrugated layer, which are integrally formed to increase the durability of the structure, so that the auxiliary pipe 2 has a certain shrinkage ability, and when the material passes through the auxiliary pipe 2, the corrugated layer located in the auxiliary pipe 2 can increase the friction between the material and the inner wall of the auxiliary pipe 2, thereby slowing down the descending speed of the material.

[0029] In some technical solutions of the utility model, a buffer component for buffering materials is provided in the auxiliary pipe 2. The buffer component can actively buffer the materials entering the auxiliary pipe 2, release the kinetic energy generated when the materials fall from a height, and avoid the initial speed of the materials being too high.

[0030] In some technical schemes of the utility model, the buffer assembly includes a mounting frame 7 fixed to the end of the first pipeline 1, the mounting frame 7 is placed in the auxiliary pipeline 2, a conical buffer 6 is rotatably provided on the mounting frame 7, the small diameter end of the buffer 6 is opposite to the first pipeline 1, a channel is left between the large diameter end of the buffer 6 and the auxiliary pipeline 2, and a driving motor 8 is provided on the mounting frame 7 which is transmission-connected with the buffer 6. The mounting frame 7 is fixed to the end of the first pipeline 1 by welding, and the buffer 6 is a metal shell, which is rotatably arranged in the middle of the mounting frame 7 through a rotating shaft, and can divert the material, so that the driving motor 8 arranged on the mounting frame 7 can drive the buffer 6 located on the mounting frame 7 to rotate in the auxiliary pipeline 2, so that the material falling on the arc surface of the buffer 6 is thrown and processed so that the material contacts the inner wall of the auxiliary pipeline 2, thereby further buffering the descending speed of the material, reducing the flying and scattering of the material, reducing the labor intensity of the manual labor, better protecting the environment, and saving a large amount of raw materials such as alumina and crushed materials to reduce production costs.

[0031] In some technical solutions of the utility model, an annular dust collecting member 9 connected to an external negative pressure device is installed on the mounting frame 7. The annular dust collecting member 9 is an annular pipe, an annular through groove is provided on the outer wall of the annular pipe, and output pipes are provided at both ends of the annular pipe on the inner wall, and the output pipes are connected to the external negative pressure device, so as to absorb dust and other substances in the material scattered after being diverted by the buffer member 6 from the material, thereby improving the cleanliness of the material.

[0032] In some technical solutions of the utility model, a flexible rubber layer is laid on the inner wall of the feed pipe 4. The rubber layer has good abrasive properties, which can extend the service life of the feed pipe 4, and the combination of the rubber layer and the cotton and linen layer can improve the buffering effect of the feed pipe 4 on the material, and the feed pipe 4 can be pulled and moved freely in the electrolytic cell, so as to lower the material to a suitable position in the electrolytic cell.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
