Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrode production equipment, in particular to a multifunctional overhead crane for cathode graphitization. Background Technique

[0002] The graphite cathode is characterized in that the cathode carbon block is composed of 30-60% electrically calcined anthracite with a particle size less than 8 mm, 15-30% roasted scraps, 10-50% graphite and 15-25% pitch. The production method of the high-graphite cathode carbon block includes batching, kneading, molding and roasting. The cathode carbon block produced by this method has the characteristics of high conductivity, sodium erosion resistance, good mechanical strength and high temperature resistance. Using this cathode carbon block can effectively improve the service life of the aluminum electrolytic cell. The roasting furnace is a key equipment for carbon production. When taking out the produced graphite cathode from the roasting furnace, a multifunctional overhead crane is needed to take it out. However, when taking it out, because the cathode resistance material around the graphite cathode is filled tightly, the existing overhead crane is inconvenient to fix it when lifting the graphite cathode. And when lifting the graphite cathode, it is necessary to lift and loosen it multiple times to make the cathode resistance material and the graphite cathode loose. Obviously, it is inconvenient to perform the above operations with a conventional lifting device. Content of the Utility Model

[0003] The purpose of the utility model is to provide a multifunctional overhead crane for cathode graphitization in order to solve the above problems.

[0004] The utility model realizes the above purpose through the following technical solutions:

[0005] A multifunctional overhead crane for cathode graphitization includes a platform assembly. Main beams are provided on both the front and rear sides of the platform assembly. Big cars are provided at both ends of the main beams. An overhead crane support for supporting it is provided below the big cars. A material suction and discharge assembly for placing and sucking the cathode resistance material is provided on the platform assembly. A clamp assembly for lifting or placing the graphite cathode is provided on the main beam.

[0006] The material suction and discharge assembly mainly consists of a main material bin, a cyclone dust collector, a centrifugal fan, a bag dust collector and a cooler. A vacuum pump for sucking the cathode resistance material is provided on the platform assembly, and the vacuum pump and the feeding end of the main material bin are connected through a pipeline assembly.

[0007] The clamp assembly includes a lifting assembly. The lifting assembly is installed at the rear side position of the platform assembly. A clamping assembly for clamping and fixing the graphite cathode is installed at the lower end of the lifting assembly. A clamping limit component is provided on the clamping assembly.

[0008] Preferably: The cyclone dust collector is installed at a position on the platform assembly close to the main material bin, and a bag dust collector is provided on the front side of the cyclone dust collector.

[0009] Preferably, the cooler is located between the cyclone dust collector and the bag filter, and a centrifugal fan is provided on the bag filter.

[0010] Preferably, the cyclone dust collector, the bag filter and the cooler are all connected through a pipeline assembly.

[0011] Preferably, auxiliary beams for moving on the main beam are provided on both sides of the platform assembly, and trolleys are provided at the front and rear ends of the auxiliary beams.

[0012] Preferably, a dust discharging and lifting mechanism for controlling the discharge of the cathode resistance material inside is provided at the discharging end of the main material bin, and walking limit components are provided on both the trolley and the large vehicle.

[0013] The beneficial effects compared with the prior art are as follows: The resistance material around the graphite cathode is sucked and collected through the material suction and discharge assembly part, and can be discharged into the lower furnace chamber or material bin. At the same time, the graphite cathode clamped by the clamping assembly is lifted upward, and the trolley drives the clamping assembly and the graphite cathode to move, so as to facilitate the quick removal of the graphite cathode and placement in the workshop storage area or the placement of the cathode to be graphitized from the workshop into the graphitization furnace.

[0029] The present utility model will be further described below with reference to the accompanying drawings:

[0030] As Figures 1 - 11 shown, a multi-functional overhead crane for cathode graphitization includes a platform assembly 1. Main beams 14 are provided on both the front and rear sides of the platform assembly 1. Gantries 12 are provided at both ends of the main beams 14. An overhead crane support 13 for supporting it is provided below the gantries 12. A material suction and discharge assembly for placing and sucking cathode resistance materials is provided on the platform assembly 1. A jig assembly for lifting or placing graphite cathodes is provided on the main beam 14;

[0031] In this embodiment: The material suction and discharge assembly mainly consists of a main material bin 9, a cyclone dust collector 51, a centrifugal fan 6, a bag dust collector 52 and a cooler 10. There is a vacuum pump 4 on the platform assembly 1 for sucking the cathode resistance material, and the vacuum pump 4 and the feed end of the main material bin 9 are connected through a pipeline assembly 2. The cyclone dust collector 51 is installed at a position on the platform assembly 1 close to the main material bin 9. There is a bag dust collector 52 on the front side of the cyclone dust collector 51. The cooler 10 is located between the cyclone dust collector 51 and the bag dust collector 52. There is a centrifugal fan 6 on the bag dust collector 52. The cyclone dust collector 51, the bag dust collector 52 and the cooler 10 are all connected through a pipeline assembly 2. The discharge end of the main material bin 9 is provided with a dust discharging and lifting mechanism 3 for controlling the discharge of the cathode resistance material inside it. Walking limit components 11 are provided on both the trolley 16 and the gantry 12. The cathode resistance material around the graphite cathode is sucked into the main material bin 9 for storage and reuse by the vacuum pump 4, and it is convenient to take out the graphite cathode. In addition, the cyclone dust collector 51, the centrifugal fan 6 and the bag dust collector 52 are used to suck away the dust generated when the main material bin 9 discharges the cathode resistance material, avoiding the situation of dust scattering.

[0032] In this embodiment: The fixture assembly includes a lifting assembly 71. The lifting assembly 71 is installed at the rear side position of the platform assembly 1. A clamping assembly 72 for clamping and fixing the graphite cathode is installed at the lower end of the lifting assembly 71. A clamping limit component 8 is provided on the clamping assembly 72. The graphite cathode is clamped by the clamping assembly 72, and the clamping assembly 72 and the graphite cathode are driven to move up and down by the lifting assembly 71.

[0033] In this embodiment: Auxiliary beams 15 for moving on the main beam 14 are provided on both sides of the platform assembly 1. Trolleys 16 are provided at both the front and rear ends of the auxiliary beam 15. The trolley 16 is used to drive the auxiliary beam 15 to move on the main beam 14, so as to adjust the positions for sucking the cathode resistance material and the clamping position.

[0034] Working principle: When lifting the graphite cathode, the gantry 12 on the main beam 14 moves along the overhead crane support 13 to move the platform assembly 1 above the graphite cathode, and then the trolley 16 on the auxiliary beam 15 moves along the main beam 14. During this process, the walking limit component 11 is used to detect the moving positions of the gantry 12 and the trolley 16;

[0035] When the clamping assembly 72 on the platform assembly 1 is located above the graphite cathode, the lifting assembly 71 drives the clamping assembly 72 to move downward. When the clamping assembly 72 is located at the position of the graphite cathode, the graphite cathode is clamped and fixed by the clamping assembly 72, and then the graphite cathode is lifted upward by the lifting assembly 71. During this process, the clamping limit component 8 is used to detect the clamping state of the clamping assembly 72;

[0036] In addition, before lifting the graphite cathode, the cathode resistance material around the graphite cathode is evacuated by the vacuum pump 4, and then the evacuated cathode resistance material enters the main material bin 9 along the pipeline assembly 2 for collection;

[0037] In addition, the cathode resistance material in the main material bin 9 can be discharged through the ash discharging and lifting mechanism 3 on the lower side of the main material bin 9. At the same time, the cyclone dust collector 51, the centrifugal fan 6, and the bag dust collector 52 are used for dust removal during the discharging of the main material bin 9. Meanwhile, the cooler 10 is used to cool down the cathode resistance material.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
