Description

Technical Field

[0001] This invention relates to the field of gunpowder production technology, and more specifically, to a production apparatus and process for environmentally friendly magnesium gunpowder used in submerged arc furnaces. Background Technology

[0002] Cutting clay for electric arc furnaces is an indispensable material in the smelting process, and its performance directly affects the operating efficiency and smelting quality of the furnace. Traditional cutting clay production equipment for electric arc furnaces is mostly semi-automated or manually operated, resulting in low production efficiency and difficulty in guaranteeing product quality.

[0003] A search revealed that Chinese patent application number CN202320535974.4 discloses an underground drilling mud production device, including a base plate. A support leg is fixedly connected to the bottom of the base plate, a support column is fixedly connected to the top of the base plate, a feed hopper is fixedly connected to the side of the support column, a dispersing hopper is fixedly connected to the bottom of the feed hopper, a guide plate is fixedly connected to the inner wall of the feed hopper, a rotating rod is rotatably connected to the bottom of the feed hopper, a limit plate is fixedly connected to the bottom of the dispersing hopper, the bottom end of the rotating rod penetrates the top of the limit plate and extends to the bottom outside of the limit plate, and the outer wall of the rotating rod is rotatably connected to the inner wall of the limit plate. This underground drilling mud production device solves the problems of non-rounded, insufficiently strong, and slow production speed, which takes up a long time in the regular tunneling cycle, and poor blasting effect, easily causing cross-blasting, thus affecting safe production. However, it still has the following drawbacks:

[0004] (1) In the prior art, the cannon clay production device requires manual cutting of the cannon clay during the production and molding process. Manual cutting results in the cannon clay of varying lengths and poor automation, which also increases the labor intensity of the operators.

[0005] Existing gun clay production equipment uses a dispersing roller to disperse and mix the gun clay raw materials. The mixing effect is not good, and it takes a long time, resulting in low production efficiency of gun clay.

[0006] Therefore, we have made improvements to this and proposed a production device and process for environmentally friendly magnesium gunning mud for submerged arc furnaces. Summary of the Invention

[0020] This invention also provides a production process for environmentally friendly magnesium-based taphole clay for submerged arc furnaces, comprising the following steps:

[0021] S1: First, the raw materials for producing environmentally friendly magnesium clay are added into the feed hopper. Then, the second motor is started to make the drive gear rotate. The rotation of the drive gear drives the driven gear and the rotating sleeve to rotate. The rotation of the rotating sleeve drives the spline shaft, the dispersing shaft and the dispersing blades to rotate, thereby dispersing and mixing the raw materials of environmentally friendly magnesium clay. At the same time, the reciprocating telescopic cylinder is started to make the connecting plate move up and down, thereby making the rotating dispersing shaft and the dispersing blades move up and down, efficiently dispersing and mixing the raw materials of environmentally friendly magnesium clay.

[0022] S2: After the mixing is completed, the control valve is opened to transport the uniformly mixed environmentally friendly magnesium clay raw material to the conveying pipe. The first motor is started to make the drive pulley rotate. The drive pulley drives the double groove pulley, the conveying shaft and the spiral blade to rotate through the first synchronous belt, thereby extruding the environmentally friendly magnesium clay raw material. The raw material is formed and sent out through the forming head.

[0023] S3: Simultaneously, the double-grooved pulley drives the driven pulley and input shaft to rotate via the second synchronous belt. The rotation of the input shaft drives the sixth gear to rotate, which in turn drives the fifth gear and drive shaft to rotate. The rotation of the drive shaft drives the third and fourth gears to rotate, which in turn drives the second gear, gear ring, gear sleeve, and output shaft to rotate. At the same time, the first gear is in an idle state. The rotation of the output shaft drives the rotating plate to rotate, which in turn drives the connecting rod to move. The connecting rod drives the reciprocating rod to move back and forth, which in turn drives the cutting frame and wire. The reciprocating steel wire automatically cuts the formed clay. When another length of clay needs to be cut, the screw rod is rotated by turning the knob. The rotation of the screw rod moves the moving block and the adjusting frame. The movement of the adjusting frame causes the gear sleeve to slide on the gear column, so that the gear sleeve moves to the gear ring and gear column next to the first gear. At this time, the third gear on the transmission shaft drives the first gear to rotate, while the second gear is in an idle state. This adjusts the speed of the output shaft, thereby adjusting the reciprocating frequency of the steel wire to facilitate the cutting of another length of clay.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] In the solution of this invention:

[0026] 1. By setting up a cutting frame, steel wire and variable speed reciprocating structure, the shaped cannon clay is automatically cut, ensuring that the length of the produced cannon clay is uniform. It can also cut two different lengths of cannon clay, which is highly flexible. There is no need for manual cutting of the shaped cannon clay, which improves the production efficiency of cannon clay and solves the problem of inconsistent lengths of cannon clay caused by manual cutting in the existing technology.

[0027] 2. Through the set dispersing structure, the raw material of the gunning clay is fully mixed and dispersed, and the dispersing shaft and dispersing blades can also move up and down while rotating, which shortens the time for dispersing and mixing the raw material, improves the production efficiency of gunning clay, and solves the problem of poor dispersing and mixing effect and efficiency of gunning clay raw material in the existing technology.

[0043] like Figure 1 , Figure 2 , Figure 9 and Figure 10As shown, in a preferred embodiment, based on the above method, the further comprising: the dispersing structure 22 includes a bearing 2201 fixed at the center of the upper end face of the material cover 21; a rotating sleeve 2202 fixedly connected to the inner ring of the bearing 2201; the bottom end of the rotating sleeve 2202 penetrating the material cover 21 and extending to its lower part; a splined shaft 2203 slidably connected inside the rotating sleeve 2202; a connecting plate 2204 rotatably connected to the top end of the splined shaft 2203; a reciprocating telescopic cylinder 2205 fixedly connected to the upper end face of the material cover 21; the driving end of the reciprocating telescopic cylinder 2205 fixedly connected to the connecting plate 2204; a dispersing shaft 2206 fixedly connected to the bottom end of the splined shaft 2203; a set of dispersing blades 2207 evenly fixedly connected to the dispersing shaft 2206; and a driven gear 2208 fixedly connected to the rotating sleeve 2202. A second motor 2209 is fixedly connected to the upper end face of the material cover 21. The drive end of the second motor 2209 passes through the material cover 21 and is fixedly connected to a drive gear 2210 that meshes with the driven gear 2208. The second motor 2209 causes the drive gear 2210 to rotate. The rotation of the drive gear 2210 drives the driven gear 2208 and the rotating sleeve 2202 to rotate. The rotation of the rotating sleeve 2202 drives the spline shaft 2203, the dispersing shaft 2206 and the dispersing blade 2207 to rotate. At the same time, the reciprocating telescopic cylinder 2205 is activated to make the connecting plate 2204 move up and down, thereby causing the rotating dispersing shaft 2206 and the dispersing blade 2207 to move up and down. This can quickly disperse and mix the raw materials of the gun clay, shorten the mixing time and improve the efficiency of gun clay production.

[0044] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a bearing plate 23 is further provided on the outer side of the forming head 10, and a support rod 24 is fixedly connected to the lower end face of the bearing plate 23, and the end of the support rod 24 is fixedly connected to the base 1; the bearing plate 23 can support the clay output by the forming head 10, thereby facilitating the cutting of the clay.

[0045] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the bottom of the feed hopper 20 is further provided with two symmetrical and fixedly connected support columns 25, and the bottom ends of the two support columns 25 are fixedly connected with support blocks 26; the support columns 25 and support blocks 26 can support the feed hopper 20 and ensure the stability of the feed hopper 20.

[0046] Specifically, during operation / use of the environmentally friendly magnesia taphole clay production device for this submerged arc furnace: First, the raw materials for producing the environmentally friendly magnesia taphole clay are added to the feed hopper 20. Then, the second motor 2209 is started to rotate the drive gear 2210. The rotation of the drive gear 2210 drives the driven gear 2208 and the rotating sleeve 2202 to rotate. The rotation of the rotating sleeve 2202 drives the splined shaft 2203, the dispersing shaft 2206, and the dispersing blades 2207 to rotate, thereby dispersing and mixing the raw materials of the environmentally friendly magnesia taphole clay. At the same time, the reciprocating telescopic cylinder 2205 is started to move the connecting plate 2204 up and down, which in turn causes the rotating dispersing shaft 2206 and the dispersing blades 2207 to move up and down. The system efficiently disperses and mixes the environmentally friendly magnesium-based clay raw material. After mixing, the control valve 19 is opened to transport the uniformly mixed environmentally friendly magnesium-based clay raw material to the conveying pipe 3. The first motor 7 is started to rotate the drive pulley 8. The drive pulley 8 drives the double-groove pulley 6, the conveying shaft 4, and the spiral blades 5 to rotate via the first synchronous belt 9, thereby extruding the environmentally friendly magnesium-based clay raw material. The raw material is formed and sent out through the forming head 10. At the same time, the double-groove pulley 6 drives the driven pulley 1226 and the input shaft 1224 to rotate via the second synchronous belt 1227. The rotation of the input shaft 1224 drives the sixth gear 1225 to rotate, and the rotation of the sixth gear 1225 drives the fifth gear 1223. The drive shaft 1220 rotates, which in turn drives the third gear 1221 and the fourth gear 1222. The fourth gear 1222 drives the second gear 1211, the gear ring 1209, the gear sleeve 1212, and the output shaft 1203 to rotate, while simultaneously causing the first gear 1210 to idle. The rotation of the output shaft 1203 drives the rotating plate 1204 to rotate, which in turn drives the connecting rod 1205 to move. The connecting rod 1205 drives the reciprocating rod 1206 to move back and forth, which in turn drives the cutting frame 11 and the steel wire 16 to move back and forth. The reciprocating steel wire 16 automatically cuts the formed clay. If it is necessary to cut another length of taphole clay, the threaded rod 1215 is rotated by turning the knob 1216. The rotation of the threaded rod 1215 causes the moving block 1217 and the adjusting frame 1213 to move. The movement of the adjusting frame 1213 causes the toothed sleeve 1212 to slide on the toothed column 1208, so that the toothed sleeve 1212 moves to the toothed ring 1209 and the toothed column 1208 on the side of the first gear 1210. At this time, the third gear 1221 on the transmission shaft 1220 drives the first gear 1210 to rotate, and the second gear 1211 is in an idle state, thereby adjusting the speed of the output shaft 1203, and thus adjusting the reciprocating frequency of the wire 16, so as to facilitate cutting another length of taphole clay.

[0047] All technical features in this embodiment can be freely combined according to actual needs.

[0048] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.

S3: At the same time, the double-groove belt pulley (6) drives the driven belt pulley (1226) and the input shaft (1224) to rotate through the second synchronous belt (1227). The rotation of the input shaft (1224) drives the sixth gear (1225) to rotate. The rotation of the sixth gear (1225) drives the fifth gear (1223) and the transmission shaft (1220) to rotate. The rotation of the transmission shaft (1220) drives the third gear (1221) and the fourth gear (1222) to rotate.
