Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis, and particularly relates to a slag scraping trolley for an electrolysis workshop. Background Art

[0002] During the production process of pre-baked anode aluminum electrolytic cells, the use of anodes is semi-continuous operation. When a new anode is used for a certain period, it becomes a spent anode. To ensure the continuous progress of aluminum electrolysis production, the spent anode needs to be replaced from the electrolytic cell, and a new anode is reinstalled to enable the electrolytic cell to operate normally and stably. When changing the anode of the electrolytic cell, first, the loose covering material is cleaned from the spent anode, and the spent anode is lifted from the electrolytic cell by means of a crane. The next task is to scrape the slag and remove the massive materials that have fallen into the high-temperature electrolyte. Currently, electrolysis workers generally temporarily place the scraped massive materials on the operating surface of the electrolysis workshop. The scraped materials will carry out high-temperature electrolyte and molten aluminum (generally about 960 °C). Under the action of the instantaneous high temperature, the operating surface expands sharply. After several high-temperature actions, "scalding" phenomena such as cracks will appear on the operating surface. After the operating surface is severely damaged, it needs to be repaired, consuming a certain amount of manpower and financial resources. Some aluminum plants generally lay steel plates on the operating surface to prevent scalding the ground, but after a period of time, there are still scald marks or severe scalds in the electrolysis workshop. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a slag scraping trolley for an electrolysis workshop, which can move according to different position requirements. Because it is relatively low from the ground, it is convenient for workers to operate, and at the same time, it can effectively prevent scalding of the operating surface; the trolley has a simple structure, is easy to use, and operates safely and reliably.

[0004] The utility model adopts the following technical scheme: A slag scraping trolley for an electrolysis workshop includes a vehicle body, a plurality of universal industrial casters arranged below the vehicle body, a hopper assembly arranged on the vehicle body, and a heat insulation board arranged between the vehicle body and the hopper assembly.

[0005] Further, the vehicle body includes a vehicle body bottom plate, criss-cross rib plates, and caster mounting seats that are fixedly installed together; caster mounting seats for installing universal industrial casters are fixedly arranged at the four corners of the vehicle body bottom plate, and rib plates are welded on the four peripheral edges of the upper surface of the vehicle body bottom plate to form a trough-shaped structure.

[0006] Further, cross rib plates are welded in the trough-shaped structure, and the trough-shaped structure and the cross rib plates form a grid structure. Heat insulation boards are installed in the plurality of small trough-shaped structures formed by the grid structure.

[0007] Further, the caster mounting seats are higher than the vehicle body so that the vehicle body is relatively low from the ground.

[0008] Further, a hopper assembly is installed above the heat insulation board. The hopper assembly is welded by a hopper bottom plate, three side baffles and a guiding and limiting plate. Baffles are welded at the three edges of the upper surface of the hopper bottom plate to form a semi-closed trough body.

[0020] For a better explanation of the present utility model for easy understanding, the technical solutions and effects of the present utility model will be described in detail below in conjunction with the drawings and through specific embodiments.

[0021] As Figures 1 to 4 shown, this embodiment provides a slag scraping trolley for an electrolysis workshop, which includes a vehicle body 2, a plurality of universal industrial casters 1 arranged below the vehicle body 2, a hopper assembly 4 arranged on the vehicle body 2, and a heat insulation board 6 arranged between the vehicle body 2 and the hopper assembly 4.

[0022] The four corners of the slag scraping trolley are equipped with universal industrial casters 1, and the universal industrial casters 1 are provided with brakes to ensure that the vehicle body 2 stops stably for convenient operation when the staff is working.

[0023] As Figure 3 shown, in this embodiment, the vehicle body 2 is welded by a vehicle body bottom plate 8, vertically and horizontally crossed rib plates 9, and caster mounting seats 7 fixedly installed together. Caster mounting seats 7 for installing universal industrial casters 1 are welded at the four corners of the vehicle body bottom plate 8. The caster mounting seats 7 are much higher than the vehicle body 2, so that the vehicle body 2 is at a lower distance from the ground, which is convenient for the staff to operate and reduces the labor intensity. The vehicle body bottom plate 8 is a rectangular or square steel plate with a thickness of 10 - 12 mm. Rib plates 9 are welded along the four peripheral edges of the upper surface of the vehicle body bottom plate 8 to form a trough-shaped structure. Cross rib plates 9 are welded in the trough-shaped structure. The trough-shaped structure and the cross rib plates 9 form a grid structure. Heat insulation boards 6 are installed in four or more small trough-shaped structures formed by the grid structure. The arrangement of the rib plates 9 increases the bearing capacity of the vehicle body 2 and installs the heat insulation board 6 in the formed grid structure.

[0024] The rib plate structure in the trough-shaped structure can also be multiple layers of rib plates with staggered distribution. Heat insulation boards 6 can be installed in the trough-shaped structures formed by each layer of rib plates. Through the heat insulation boards 6 arranged in multiple layers and staggered, it is better to avoid the ground being scalded by the slag.

[0025] As Figure 4 shown, after the heat insulation board 6 is installed, a hopper assembly 4 is installed on its upper part. In this embodiment, the hopper assembly 4 is welded by a hopper bottom plate 11, three-sided baffles, and a guiding and limiting plate 10. Baffles are welded along the three peripheral edges of the upper surface of the hopper bottom plate 11 to form a semi-closed trough body. The baffles are relatively high and lifting holes 5 are provided on all three-sided baffles. When the hopper assembly 4 is filled with materials, the hopper is lifted by the crane in the workshop through the lifting holes 5. The lifting holes 5 are connected to the crane hook by steel wires. Multiple lifting holes 5 are arranged at the same height on the baffles to ensure that the hopper is lifted smoothly.

[0026] Guide and limit plates 10 are welded to the four sides of the lower surface of the hopper bottom plate 11. The guide and limit plates 10 are matched with the vehicle body 2. The guide and limit plates 10 are relatively short, which facilitates the quick cooperation between the hopper and the vehicle body 2, and ensures that the hopper 4 can only be removed from the vehicle body 2 in the vertical direction and will not shift in the horizontal direction, preventing the hopper assembly 4 from separating from the vehicle body 2 during the horizontal movement of the trolley.

[0027] In this embodiment, a handrail 3 is fixedly installed upward on the rib plate 9 at the bottom of the middle baffle. An insulating layer is sleeved around the handrail 3, which is convenient for the staff to move the slag scraping trolley.

[0028] During the slag scraping operation of the electrolytic cell, the side without the welded baffle faces the cell chamber to facilitate the staff to semi-enclose the slag material scraped from the electrolytic cell in the tank body. The hopper assembly 4 contains high-temperature slag scraping material. Since there is an insulating board 6 between the hopper assembly 4 and the vehicle body 2, the high temperature of the hopper assembly 4 will not radiate to the floor of the electrolysis workshop, thus protecting the floor of the electrolysis workshop. The staff uses the slag scraping trolley to remove the slag material or hoist the hopper assembly 4 filled with slag material by a crane.
