Description

Technical Field

[0001] The utility model belongs to the technical field of white corundum smelting and bagging, and specifically relates to a double-layer bagging device for white corundum smelting. Background Art

[0002] White corundum abrasive is mainly made of industrial alumina powder as raw material. It is made by melting at a high temperature of more than 2000 degrees in an electric arc furnace and then cooling. It is crushed and shaped, magnetically separated to remove iron, and sieved into various particle sizes. It has a dense texture, high hardness, and sharp corners. For white corundum abrasive, the higher the alumina content, the better its hardness and grinding performance. Generally, the alumina content of white corundum is more than 99%, and the impurities mainly include silicon, iron, titanium, sodium and other substances. In particular, the sodium content of white corundum abrasive should be paid attention to. If the content is too high, it will lead to an increase in the generation of β-alumina, which will reduce the crystal hardness of white corundum, reduce the cutting ability, and easily pulverize and break.

[0003] The patent name is a bag receiving device for white corundum smelting. The patent application document with application number 2023219567282 discloses a spherical concave basin-shaped structure for holding high-temperature molten industrial alumina. Its depth is not enough. When pouring it into the bag receiving device through an electric arc furnace, it is easy to cause the high-temperature molten liquid to splash, causing waste of raw materials and threatening the personal safety of on-site personnel. At the same time, the melt formed by cooling in the existing bag receiving device is small in volume, and the melt dissipates heat quickly during the cooling and crystallization process. The upper melt is honeycomb-shaped, the middle melt has many pores, and the structure is loose and its density is not enough. The lower melt has a dense structure, and the volume density of the crushed granular material is small, and the wear resistance is poor, which affects the product performance. In order to solve the problems in the background technology, the invention is based on the above-mentioned technical problems in the prior art, and a double-layer bag receiving device for white corundum smelting has been developed, which can well solve the above-mentioned technical problems existing in the prior art.

[0013] 1. Assembly of the double-layer receiving device: Before work, first use the winch to pull the traction ear of the vibration support table to pull the vibration support table to the receiving area, then use the sling to place the lower receiving steel shell on the conical placement table of the vibration support table, and then place the upper receiving steel shell on the annular support plate of the lower receiving steel shell, and finally add the white corundum granules to the upper part of the corundum castable, and accumulate on the inner wall of the lower receiving steel shell body to form a bowl with a concave center for pouring and holding the white corundum melt.

[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0019] The utility model provides a double-layer package connection device for white corundum smelting:

[0020] like Figure 1 As shown, a vibration support table 1 is placed on the floor of the workshop, and a lower layer steel shell 2 is placed on the upper part of the vibration support table 1. Through the setting of the vibration support table 1 and the use of the vibration effect of the vibration support table 1, on the one hand, impurities in the white corundum melt are better discharged, the overflow of the white corundum melt is reduced, the safety of the working environment is improved, and the waste of raw materials and the threat to the personal safety of on-site personnel are avoided. On the other hand, the vibration effect of the vibration support table 1 can be used to discharge the gas in the white corundum melt that is statically crystallized and cooled, thereby improving the uniformity of the overall density of the white corundum melt and solving the technical problems that the melt dissipates heat quickly during the cooling and crystallization process, the upper melt is honeycomb-shaped, the middle melt has many pores, and the structure is loose and the density is insufficient.

[0021] like Figure 1As shown, the vibration support platform 1 includes wheels 11, which are fixedly arranged at the four corners of the bottom of the support body 12. The support body 12 is a hollow structure welded by I-beams. The vibration motor 13 is fixedly arranged at the bottom center of the support body 12, and the vibration motor 13 is fixedly connected to the control switch through a connecting wire; the support springs 14 are evenly fixedly distributed on the upper part of the support body 12, and a conical placement platform 15 is fixedly arranged on the upper part of the support springs 14. The conical placement platform 15 is a hollow cone-shaped conical placement platform with a closed lower part and an open upper part; the traction ears 16 are fixedly arranged at the middle position of the left and right ends of the support body 12, and the traction ears 16 are fixedly connected to the traction end of the winch. The above-mentioned setting of the vibration motor 13 provides vibration power for the vibration support platform 1, and at the same time, a uniform vibration effect is formed on the conical placement platform 15 under the elastic cooperation of the support springs 14. By setting wheels 11 at the four corners of the bottom of the support body 12 and using a winch to pull the traction ears 16, the vibrating support platform 1, the lower layer steel shell 2 and the upper layer steel shell 3 can be moved back and forth between the connection area and the designated crystallization cooling area.

[0022] like Figure 1 As shown, the lower layer steel shell 2 includes a lower layer steel shell body 21, which is a hollow cone-shaped body with a closed lower part and an open upper part, and a lifting lug 22 is evenly arranged around the outer circumference of the lower layer steel shell body 21; an annular support plate 23 is fixedly arranged near the upper part of the lower layer steel shell body 21, a corundum castable 24 is cast and formed at the bottom of the lower layer steel shell body 21, and white corundum granules 25 are supplemented and stacked on the upper part of the corundum castable 24, and are accumulated on the inner wall of the lower layer steel shell body 21 to form a bowl shape with a concave center, and a longitudinal reinforcing rib 26 is evenly arranged around the inner wall of the lower layer steel shell body 21. The above arrangement of the lifting lug 22 facilitates the lifting or placement of the lower layer steel shell 2 by the lifting tool. The above-mentioned annular support plate 1 23 is provided to, on the one hand, strengthen the support for the lower layer steel shell body 21 to prevent the lower layer steel shell body 21 from being deformed due to high temperature; on the other hand, it provides a corresponding placement platform for the upper layer steel shell 3. The above-mentioned casting and molding by the corundum castable 24 plays a role in protecting the lower layer steel shell body 21. The above-mentioned white corundum granular material 25 is supplemented and piled on the upper part of the corundum castable 24, and is piled on the inner wall of the lower layer steel shell body 21 to form a bowl shape with a concave center. The main purpose of doing so is: on the one hand, the block-shaped white corundum melt formed by crystallization cooling can be demoulded smoothly (the white corundum granular material is in bulk); on the other hand, it can prevent the leakage of the white corundum melt between the lower layer steel shell 2 and the upper layer steel shell 3.

[0023] like Figure 1As shown, the upper layer steel shell 3 is placed on the annular support plate 1 23 of the lower layer steel shell body 21, the upper layer steel shell 3 includes an upper layer steel shell body 31, an annular support plate 2 32 is fixedly arranged in the middle of the inner wall of the upper layer steel shell body 31, longitudinal reinforcement ribs 2 33 are evenly arranged around the inner wall of the upper layer steel shell body 31, a hollow ball casting material layer 34 is cast on the inner wall of the upper layer steel shell body 31, a corundum brick layer 35 is built around the inner wall of the upper layer steel shell body 31 on the hollow ball casting material layer 34, and a corundum gunning material layer 36 is melt-gunned on the corundum brick layer 35. The above-mentioned annular support plate 2 32 and longitudinal reinforcement ribs 2 33 can prevent the upper layer steel shell body 31 from being deformed due to high temperature. Through the pouring of the hollow ball casting material layer 34 and the laying of the corundum brick layer 35, the double-layer connection device moves the cooling area, the white corundum melt in the double-layer connection device is kept warm for more than 24 hours, and the hollow ball casting material layer and the corundum brick layer extend the crystallization time of the white corundum melt, avoiding the impurity enrichment and poor crystal development caused by rapid cooling, and better eliminating the impurities not discharged during the smelting process. The formed white corundum has coarse crystals, a tight structure, acid and alkali corrosion resistance, high temperature resistance, and good thermal stability. The above-mentioned spraying of the corundum gunning material layer 36 can improve the smoothness of the inner wall of the lower layer connection steel shell body 21, and can make the crystallized and cooled white corundum melt smoothly demolded.

[0024] like Figure 1 As shown, the working process of this double-layer packaging device for white corundum smelting is:

[0025] 1. Assembly of the double-layer receiving device: Before work, first use the winch to pull the traction ear 16 of the vibration support platform 1 to pull the vibration support platform 1 to the receiving area, then use the sling to place the lower receiving steel shell 2 on the conical placement platform 15 of the vibration support platform 1, and then place the upper receiving steel shell 3 on the annular support plate 23 of the lower receiving steel shell 2, and finally add the white corundum granular material 25 to the upper part of the corundum casting material 24, and accumulate on the inner wall of the lower receiving steel shell body 21 to form a bowl with a concave center for pouring and holding the white corundum melt 4. At the same time, it is necessary to start the vibration motor 13 of the vibration support platform 1 through the control switch to make the vibration support platform 1 produce a uniform vibration effect.

[0026] 2. Crystallization cooling process of double-layer packaging device for white corundum smelting: During the pouring process of white corundum melt from the high position in the furnace to the double-layer packaging device for white corundum smelting, the vibration of the vibration support platform 1 makes the impurities in the melt discharged better, reduces the melt overflow, improves the safety of the working environment, avoids the waste of raw materials and threatens the personal safety of on-site personnel. After the pouring of the white corundum melt 4 is completed, the traction ear 16 of the vibration support platform 1 is pulled by the winch to drive the lower layer steel shell 2 and the upper layer steel shell 3 on the support body 12 and the conical placement platform 15 to be pulled to the designated crystallization cooling area for natural cooling. At this time, the hollow ball casting material layer 34 and the corundum brick layer 35 in the upper layer steel shell 3 play a good role in heat preservation, which reduces the heat loss in the white corundum melt 4 to the greatest extent, prolongs the cooling and crystallization process of the white corundum melt, and fully discharges the impurities in the white corundum melt 4, forming a white corundum melt with coarse crystals and tight structure, and the white corundum crystal hardness is increased, and the cutting ability is enhanced. After crystallization and cooling for 24 hours, the upper steel shell 3 and the lower steel shell 2 are turned over and lifted by a hoist, and the white corundum frit is demolded and separated from the upper steel shell 3 and the lower steel shell 2 by the gravity of the white corundum frit. After the demolding of the white corundum frit is completed, when the white corundum melt 4 needs to be crystallized and cooled again, the corundum spraying material layer 36 is first sprayed on the corundum brick layer 35 of the upper steel shell 3, and the upper steel shell 3 is stably placed on the annular support plate 23 of the lower steel shell 2 as required. At the same time, the white corundum granular material 25 is added to the lower steel shell 2 in time, and the next step of the packaging work is started. After demolding, the center temperature of the white corundum frit is above 900℃, and it continues to slowly cool and crystallize in the material yard, further eliminating impurities that are not discharged during the smelting process, stabilizing the product quality, and meeting the customer needs of white corundum abrasives.
