Description

Technical Field

[0001] This invention relates to the field of fused magnesia raw material technology, and more specifically, to an integrated automatic crushing, screening and impurity sorting equipment for fused magnesia raw materials. Background Technology

[0002] Fused magnesia refers to magnesia products obtained through high-temperature electrofusion processing. It has characteristics such as high purity, high density, high strength, and good thermal shock resistance. Fused magnesia has a wide range of applications in metallurgy, building materials, chemical industry, etc. In particular, it is an indispensable raw material in the preparation of fused refractory materials. Through specific processes and equipment, fused magnesia can be produced automatically to meet the needs of large-scale industrial production.

[0003] According to patent document CN114524665A, a method for preparing fused magnesia-zirconium sand is disclosed. This method includes raw material preparation, mixing, and electric arc furnace smelting. The specific steps are as follows: Select lightly calcined magnesia powder with a magnesia content of over 80%, ground to a particle size of 30-200 mesh, as raw material; select zirconium oxide powder with a zirconium content of over 95%, 30-200 mesh, as auxiliary material; mix the above raw materials and auxiliary materials evenly using a mixer to obtain smelting raw materials; add the smelting raw materials to an electric arc furnace and continuously smelt at 2860-3300℃ for 7-10 hours; after smelting, use a hot air circulation temperature control system for heat preservation, cooling, crystallization, graded crushing, and sieving to obtain fused magnesia-zirconium sand. Compared with fused magnesia, it has advantages such as a small coefficient of thermal expansion, good thermal shock resistance, and good slag resistance. Different product specifications can replace fused magnesia in various fields such as aerospace, electronics, steel, and metallurgy.

[0004] Current fused magnesia crushing and separation equipment is limited to crushing fused magnesia raw materials, but it cannot ensure the consistency of product size. Therefore, workers must collect the finished product and screen it, and then crush it again. This process is cumbersome and significantly increases the labor intensity of workers. In addition, fused magnesia raw materials may contain impurities. If they are not effectively separated, these impurities will have an adverse effect on the quality of the final product.

The left and right sides of the storage box 316 are fixedly connected to the top of the inner side of each of the two vertical Z-shaped connecting rods 25. The bottoms of the two discharge funnels 317 are connected to the two discharge slots 218 opened on the top of the discharge plate 217. Alignment is achieved, with the top of the baffle 315 fitting against the bottom of the two discharge funnels 317. A discharge opening size adjustment assembly 318 is provided on the inner side of the baffle 315 and the abutment plate 311. The discharge opening size adjustment assembly 318 includes multiple moving rods 3181, each with a moving rod abutment block 3182 fixedly connected to its top rear side. The outer walls of the multiple moving rod abutments 3182 are slidably connected to the inner walls of the two sets of inclined grooves 313 opened in the abutment plate 311. Both sides of the inner wall of 181 are slidably connected to the outer walls of the two columnar crossbars 34. The front sides of the multiple movable rods 3181 are fixedly connected to vertical stop bars 3183. The rear sides of the multiple vertical stop bars 3183 are slidably connected to the front side of the feed plate 217.

Material-blocking side plates 3185 are fixedly connected to the inner sides of the two inner vertical stop bars 3183 and the outer sides of the two outer vertical stop bars 3183.

[0033] When it is necessary to crush the fused magnesia raw material, the hydraulic push rod 211 is activated first. The activation of the hydraulic push rod 211 drives the column push rod 36 to move forward, which in turn drives the groove plate connecting block 312 to move forward, thereby driving the groove plate 311 to move forward. Then, the two sets of inclined grooves 313 opened at the bottom of the groove plate 311 abut against the moving rod abutment block 3182 at the top of the multiple moving rods 3181, which causes the multiple moving rod abutment blocks 3182 to move inward, making the opening of the feeding port at the front of the feeding plate 217 smaller. At this time, impurities and smaller fused magnesia raw materials in the feeding process can fall directly through the feeding plate 217 to the top of the total feeding inclined plate 37, and fall through the filter screen 38 to the inside of the collection frame 219 for collection during the sliding process.

[0034] Meanwhile, as the abutment plate 311 moves forward, it drives the inner baffle 315 to move forward via the two front connecting uprights 314, no longer obstructing the two discharge funnels 317 at the bottom of the storage box 316. At this time, the storage box 316 discharges the fused magnesia raw material through the two discharge funnels 317 at the bottom to the top of the inclined plate 216 set on the inner wall of the two discharge troughs 218 opened on the discharge plate 217. At this time, the fused magnesia raw material slides forward along the top of the inclined plate 216. At the same time as sliding, the dual-shaft motor 29 is started. The dual-shaft motor 29 drives the two conical rotating blocks 210 fixed on its left and right output ends to rotate. The rotation of the two conical rotating blocks 210 is then connected to the two rotating wheels 21 by the outer wall. The outer wall of 4 is attached to drive the two rotating wheels 214 to rotate. The rotation of the two rotating wheels 214 causes the columnar spring rods 212 fixed at their top to slide on the inner wall of the two inverted L-shaped guide side plates 27. At the same time, the two columnar spring rods 212 drive the push block 213 fixed at their top to move during the sliding process. The push block 213 moves and then drives the inclined plate 216 to move up and down through the inclined plate hinge block 215 connected to its outer wall. The up and down movement of the inclined plate 216 causes the fused magnesia raw material on the inner wall of the two feeding grooves 218 opened at the top of the feeding plate 217 to be bumped and slowly slide down, so as to avoid the fused magnesia raw material blocking the feeding grooves 218 during the sliding process due to the excessive feeding speed.

[0035] After a suitable amount of fused magnesia raw material is fed in, and impurities and smaller fused magnesia raw material have been completely discharged from the inner wall of the feeding trough 218 opened by the feeding plate 217, the hydraulic push rod 211 is activated to reset the trough plate 311 and multiple moving rods 3181, thereby restoring the front openings of the feeding plate 217 and the two feeding troughs 218 to their original size. At this time, the larger fused magnesia raw material remaining in the inner wall of the feeding trough 218 continues to slide down through the inclined plate 216 to the top of the total feeding inclined plate 37. The normally sized fused magnesia raw material is larger than the mesh of the filter screen 38, so it falls on the top of the total feeding inclined plate 37 and continues to slide forward along the total feeding inclined plate 37 until it slides to the top front feed inlet of the crushing mechanism 1 and enters the interior of the crushing mechanism 1 for crushing.

[0036] Working principle of this invention: When it is necessary to crush fused magnesia raw materials, the hydraulic push rod 211 is first activated. The activation of the hydraulic push rod 211 drives the columnar push rod 36 to move forward, which in turn drives the groove plate connecting block 312 to move forward, thereby driving the groove plate 311 to move forward. Then, the two sets of inclined grooves 313 opened at the bottom of the groove plate 311 abut against the moving rod abutment blocks 3182 at the top of multiple moving rods 3181, thereby causing the multiple moving rod abutment blocks 3182 to move inward, making the opening at the discharge point on the front side of the discharge plate 217 smaller. At the same time, as the groove plate 311 moves forward, it drives the baffle 315 on its inner side to move forward through the two front connecting uprights 314, no longer pressing against the bottom of the storage box 316. The two feeding funnels 317 are blocked. At this time, the storage box 316 feeds the fused magnesia raw material through the two feeding funnels 317 at the bottom to the top of the inclined plate 216 set on the inner wall of the two feeding troughs 218 opened in the feeding plate 217. At this time, the fused magnesia raw material slides forward along the top of the inclined plate 216. At the same time as it slides down, the dual-shaft motor 29 is started. The dual-shaft motor 29 drives the two conical rotating blocks 210 fixed on its left and right output ends to rotate. The rotation of the two conical rotating blocks 210 then drives the two rotating wheels 214 to rotate through the outer wall of the two rotating wheels 214. The rotation of the two rotating wheels 214 drives the columnar spring rod 212 fixed at its top to move against the inner wall of the two inverted L-shaped guide side plates 27. During the sliding process, the two columnar spring rods 212 drive the push block 213 fixed at their top to move. The movement of the push block 213, in turn, drives the inclined plate 216 to move up and down through the inclined plate hinge block 215 rotatably connected to its outer wall. The up and down movement of the inclined plate 216 causes the fused magnesia raw material on the inner wall of the two feeding grooves 218 opened at the top of the feeding plate 217 to be bumped and slowly slide down. At this time, impurities and small-sized fused magnesia raw materials in the feeding process can fall directly through the feeding plate 217 to the top of the total feeding inclined plate 37, and fall through the filter screen 38 into the collection frame 219 for collection during the sliding process. After a suitable amount of fused magnesia raw material is fed, and the impurities are removed, the material is collected. When the smaller fused magnesia raw material has been completely discharged from the inner wall of the discharge trough 218 opened by the discharge plate 217, the hydraulic push rod 211 is activated to reset the trough plate 311 and multiple moving rods 3181, thereby restoring the front openings of the discharge plate 217 and the two discharge troughs 218 to their original size. At this time, the larger fused magnesia raw material remaining in the inner wall of the discharge trough 218 continues to slide down through the inclined plate 216 to the top of the total discharge inclined plate 37. The normal-sized fused magnesia raw material is larger than the mesh of the filter screen 38, so it falls on the top of the total discharge inclined plate 37 and continues to slide forward along the total discharge inclined plate 37 until it slides to the top front feed port of the crushing mechanism 1 and enters the interior of the crushing mechanism 1 for crushing.
