At this time, the raw material barrel 322 filled with high-concentration high-temperature resistant and corrosion-resistant raw materials is facing The corresponding spray gun 323 is in a closed state, that is, the switch plate 321 in the spray gun 323 is in a closed state, and the spray gun 323 corresponding to the other raw material barrel 322 filled with low-concentration high-temperature resistant and corrosion-resistant raw materials is in an open state, that is, the switch plate 321 in the spray gun 323 is in an open state, and the threaded inner cylinder 310 spirally rotates downward, and the low-concentration raw materials are sprayed to the downward part of the petrochemical device outlet through the spray gun 323. Since the corrosion resistance and high temperature requirements at the petrochemical device outlet are higher, the inner lining at the petrochemical device outlet has higher requirements for high temperature resistance and corrosion resistance.

[0048] The working principle of this embodiment is as follows: the rotation of the bottom motor 104 drives the motor wheel 105 to rotate, and the bottom transmission belt 106 drives the bottom transmission wheel 110 and the internal threaded column 116 to rotate, and the rotation of the internal threaded column 116 drives the outer slide cylinder 111 to rise along the outer fixed cylinder 103, and at the same time the internal threaded column 116 drives the middle threaded cylinder 115 to rotate, and the rotation of the middle threaded cylinder 115 drives the middle slide cylinder 112 to rise, and the middle threaded cylinder 115 simultaneously drives the outer threaded cylinder 114 to rotate, and the outer threaded cylinder 114 drives the inner slide cylinder 113 to rise, thereby realizing the simultaneous rise of the outer slide cylinder 111, the middle slide cylinder 112 and the inner slide cylinder 113, thereby realizing the multi-stage rise of the lifting frame 201, and the four tensioning ropes 109 are straightened by the torsion spring between the tension wheel 107 and the wheel frame 108 to keep the balance of the lifting frame 201. The controller 203 controls the rotating motor 202 to rotate, thereby driving the motor gear 206 to rotate, thereby driving the lower docking gear 207, the rotating column 205 and the upper bevel gear 208 to rotate, thereby driving the side bevel gear 209 and the inner idler rod 212 to rotate, and through the inner idler rod 212 and the inner sliding rod 210, the internal threaded tube 216 and the middle threaded tube 211 are driven to rotate together, and through the thread transmission between the middle threaded tube 211 and the inner wall of the lifting frame 201, the middle threaded tube 211 is driven to slide outward, and at the same time, through the thread transmission between the internal threaded tube 216 and the inner wall of the middle threaded tube 211, the internal threaded tube 216 is driven to slide outward at the same time, thereby driving the telescopic tube 214 and the extension frame 301 to extend, and the telescopic tube 214 is kept horizontal by the counterweight block 215, when the internal threaded tube 216 moves outward.When the external thread barrel 305 reaches the top of the petrochemical device, the motor 302 is inserted into the rotation to drive the upper motor gear 303 to rotate, thereby driving the tooth column 304 to rotate, thereby driving the descending gear 306 and the external thread barrel 305 to rotate. Under the cooperation of the internal thread seat 307 and the thread of the external thread barrel 305, the external thread barrel 305 and the descending gear 306 begin to spirally rotate downward. In the initial state, the spray gun 323 corresponding to the raw material barrel 322 containing a high concentration of high temperature resistant and corrosion-resistant raw materials is in an open state, that is, the switch plate 321 in the spray gun 323 is in an open state. , the spray gun 323 corresponding to the other raw material barrel 322 containing a low-concentration high-temperature resistant and corrosion-resistant raw material is in a closed state, that is, the switch plate 321 in the spray gun 323 is in a closed state, and the external threaded barrel 305 rotates with the threaded inner barrel 310 to rotate downward, so that the high-concentration raw material is sprayed to the outlet of the petrochemical device through the spray gun 323. When the descending gear 306 contacts the switch 308, the external threaded barrel 305 descends to the lowest position. At this time, the switch 308 controls the actuating electric cylinder 309 to start extending, thereby passing the slider 312 and the slider 310 to rotate downward. The groove 313 drives the threaded inner cylinder 310 to spirally descend. When the threaded inner cylinder 310 spirally descends, the gear shaft 316 and the upper gear 315 are driven to spirally descend. Under the action of the fixed tooth block 314, the upper gear 315, the gear shaft 316 and the lower gear 317 are driven to rotate. The two transmission wheels 319 and the switch plate 321 are driven to rotate through the transmission belt 320. When the upper gear 315 descends to the bottom of the fixed tooth block 314, the transmission wheel 319 and the switch plate 321 rotate 90 degrees. At this time, the raw material barrel 322 filled with high-concentration high-temperature resistant and corrosion-resistant raw materials is facing The corresponding spray gun 323 is in a closed state, that is, the switch plate 321 in the spray gun 323 is in a closed state, and the spray gun 323 corresponding to the other raw material barrel 322 filled with low-concentration high-temperature resistant and corrosion-resistant raw materials is in an open state, that is, the switch plate 321 in the spray gun 323 is in an open state, and the threaded inner cylinder 310 spirally rotates downward, and the low-concentration raw materials are sprayed to the downward part of the petrochemical device outlet through the spray gun 323. Since the corrosion resistance and high temperature requirements at the petrochemical device outlet are higher, the inner lining at the petrochemical device outlet has higher requirements for high temperature resistance and corrosion resistance.
