Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum electrolysis production, and particularly relates to a support for an anode rod steel claw group used in aluminum electrolysis. Background Art

[0002] After years of development, the aluminum electrolysis cell has experienced the transformation from a side-injected self-baked anode electrolysis cell to an up-injected self-baked anode electrolysis cell, and then to a large pre-baked aluminum electrolysis cell. The modern aluminum industry production generally adopts the cryolite-aluminum oxide molten salt electrolysis method, and the main equipment is a large pre-baked anode aluminum electrolysis cell. Therefore, the anode group has become one of the important raw materials in aluminum electrolysis production, mainly composed of an anode carbon block, steel claws, and a guide rod. Its production process includes processes such as steel claw production, guide rod welding, and anode carbon block casting. Generally, the anode carbon blocks are produced and formed by a carbon factory, the steel claws are purchased, the guide rods are cast and formed, and then the steel claws and the guide rods are welded in a maintenance workshop, and then poured into a complete anode group by an anode assembly workshop.

[0003] After the guide rod and the steel claw are welded in the maintenance workshop, the length of the guide rod steel claw group is generally about 3 meters, and there are many inconveniences and safety risks during its storage and transportation. Inside the workshop, it can be moved by single-piece hoisting. When moving it to the assembly workshop, it is generally forklifted. Its size is too large, it is easy to tip over, there is a high safety risk, and the operation efficiency is very low; there are also situations of tipping over and inconvenient operation during the placement process. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a support for an anode rod steel claw group used in aluminum electrolysis to solve the above problems.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A support for an anode rod steel claw group used in aluminum electrolysis includes a base and a plurality of intermediate support beams arranged on the base. A clamping groove is arranged between adjacent intermediate support beams. The intermediate support beams and the clamping groove are arranged on the central axis of the base. Side support plates are symmetrically arranged on both sides of the intermediate support beams. The bottom surface of the side support plates is fixedly connected to the top surface of the base. The intermediate support beams and the side support plates are both perpendicular to the top surface of the base. The side wall of the side support plates is fixedly connected to the side wall of the intermediate support beams.

[0007] In order to further implement the utility model, the side support plates are right-angled isosceles triangles.

[0008] In order to further implement the utility model, the base includes a "T"-shaped bottom plate and a long groove body arranged in the concave part of the bottom plate. The outside of the long groove body is flush with both sides of the bottom plate.

[0009] In order to further implement the utility model, the thickness of the long groove body is greater than the thickness of the bottom plate.

[0010] To further implement the present utility model, the axis of the long groove body is parallel to the central axis of the base.

[0011] To further implement the present utility model, the thickness of the base steel plate is not less than 50 mm, the length of the middle support beam is equal to the length of the base, and the width is greater than 15 cm. Generally, the weight of the guide bar steel claw group of modern large-scale preliminary electrolytic cells is about 500 kg. As the load-bearing part, the base must have sufficient strength. Therefore, the thickness of the base steel plate is not less than 50 mm to ensure its strength; the limitation of the length and width of the middle support beam and the dimension setting ensure the strength of the middle support beam, enable it to support the guide bar steel claw group to keep vertical, and ensure that the guide bar steel claw group can be smoothly placed on the support and the center of gravity is on the central axis of the support, improving the stability of the support and the safety during the forklift transportation process.

[0012] To further implement the present utility model, the width of the middle support beam is less than the distance between the two inner claws of the steel claw.

[0013] To further implement the present utility model, the through-hole size of the long groove body is greater than the external size of the forklift arm. The through-hole is used for the forklift arm to pass through for convenient operation. The long groove body is made of rectangular steel pipe, and its height is greater than the height of the base. The through-hole size should be greater than the external size of the forklift arm to ensure that the present utility model can be reasonably matched with the forklift operation.

[0014] The beneficial effects of the present utility model compared with the prior art are as follows:

[0015] There are multiple card slots, which are evenly distributed on the upper part of the middle support beam. Each card slot is a working position for a guide bar steel claw group. The width of the card slot is greater than the width of the steel claw cross beam, and the depth is greater than the height of the steel claw cross beam. At the same time, the difference between the height of the middle support beam and the depth of the card slot is less than the height of the steel claw head. The setting of the above dimensions ensures that the steel claw cross beam can be embedded inside the card slot, and at the same time, the four claw heads of the steel claw fall on the upper surface of the base, and the two inner claws are arranged on both sides of the middle support beam, so as to ensure that the center of gravity of each guide bar steel claw group is on the central axis of the support.

[0016] There are multiple side support plates, which are right-angled triangles and are symmetrically distributed on both sides of the middle support beam. The two right-angled sides are respectively welded to the side surface of the middle support beam and the upper surface of the base; the side support plates on both sides of the middle support beam are evenly distributed, and each distribution point is the midpoint position between two adjacent card slots. The setting of the side support plates improves the overall strength and structural stability of the support.

[0017] The device of the utility model has a simple structure and low manufacturing cost, and ordinary technicians in the field of aluminum electrolysis anode group production technology can fabricate it by themselves according to the technical solution; the usage method is simple, and technicians in this industry can understand and apply it to production according to the technical solution; through the implementation of the utility model, during the processing of the guide bar steel claw group and the storage and transportation before casting the anode carbon block, the operation is convenient, the operation efficiency is improved, and the safety risk is reduced.
