The raw materials are crushed into a certain particle size and then added with additives for batching. Then they are put into the furnace for melting, cottonizing and packaging. Mineral wool and adhesives can be made into pipe insulation sleeves through molding, drying, curing and other processes. During the processing of pipe insulation sleeves, it is necessary to spray the molten slag powder into filaments. The quality of melt-blowing directly affects the stability and service life of the subsequent insulation of the pipe insulation sleeves.

[0003] The above-mentioned prior art solutions have the following defects: when the fiber mineral wool meltblown machine is blowing, the meltblown fiber will be uneven in thickness.

The molten slag powder is transported to the inside of the melt-blown die head through the feed pipe through the pressurization of the screw extruder and the flow control of the metering pump. At the same time, the air is sucked in and pressurized by the Roots blower, added through the air heater, and then input into the air inlet slot through the air inlet pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When it is necessary to detect whether the air volume of the two air-jetting slots is stable and uniform, the first electric telescopic cylinder is extended to place the rotating piece directly under the spinneret. At this time, the third electric telescopic cylinder is extended to place the correcting mechanism directly under the rotating piece. At this time, the rotating piece is correspondingly arranged with the rotating piece slot, and the second electric telescopic cylinder is contracted to drive the correcting mechanism to move upward as a whole. Through the inclined setting of the upper end of the first correcting block and the vertical setting of the first correcting block, the upward-moving first correcting block can push the inclined rotating piece to make the rotating piece tend to a vertical state. Through the inclined setting of the upper end of the second correcting block and the vertical setting of the second correcting block The upward movement of the deflection block allows the rotating piece to rotate to a vertical state and slide with the rotating piece slot. At this time, the unified adjustment of the angles of multiple rotating pieces is achieved. After the adjustment is completed, the second electric telescopic cylinder is extended and the third electric telescopic cylinder is contracted to move the deviation correction mechanism to the lower end of one side of the spinneret. By starting the Roots blower, the air enters the air inlet slot through the air inlet pipe and is blown out through the air ejection slot. By observing the inclination state of the rotating piece, the stability of the air output can be intuitively observed and judged, which solves the problem that the air output of the meltblown machine is unstable and not convenient for objective and stable detection during the processing of the pipe insulation sleeve.

[0019] When the spinneret is clogged and needs to be cleaned, the power supply of the electromagnet is turned on. The electromagnet uses its own magnetic force to magnetically attract the wind shield limit mechanism downward, and the upper end of the wind shield limit mechanism releases the limit on the wind shield. At the same time, the center limit block releases the limit on the center of the wind shield. At this time, the wind shield can be rotated toward the spinneret, and the cleaning electric telescopic cylinder is extended. The guide baffle is pushed upward by the cleaning electric telescopic cylinder, thereby guiding the hot air inside the air inlet slot into the cleaning slot. The hot air enters the air jet slot through the guidance of the cleaning slot, and the high-pressure hot air pressurizes and melts the polymers and impurities blocked in the air jet slot, thereby blowing them out, thereby effectively improving the efficiency of the air jet slot cleaning, reducing the cleaning workload, and solving the problem that when processing the pipeline insulation sleeve, the meltblown die head is mostly blocked and needs to be disassembled and then the die head cleaning furnace is used to remove the polymers and impurities remaining in the die head by baking, and the cleaning process is complicated.

[0033] A method for processing an inorganic fiber mineral wool pipe insulation sleeve processing device comprises the following steps:

[0034] Step 1: adding the molten slag powder into the screw extruder 2 through the feeding mechanism 3, and the molten slag powder is transported to the inside of the melt-blowing die head 5 through the feed pipe 11 by the pressurization of the screw extruder 2 and the flow control of the metering pump. At the same time, the air is sucked and pressurized by the Roots blower 4, and then added through the air heater and input into the air inlet slot 21 through the air inlet pipe 6, and the hot air is ejected along the air ejection slot 23;

[0035] Step 2: The molten slag powder is heated again by the heating plate 12, and the temperature of the molten slag powder in the feeding trough 13 is accurately detected by the first temperature sensor 46. The molten slag powder enters the melt trough 16 through the transmission trough 15, is pressurized and ejected through the spinneret 22, is blown into filaments by the hot air in the air jet trough 23, and falls onto the rolling web forming machine 7, and blast furnace slag fibers are obtained through the cooperation of the electrostatic electret 8 and the winding and slitting machine 9;

[0036] Step 3: Mix the modified bonding particles and blast furnace slag fibers in a mass ratio of 1:5 and place them in a mold, press them into shape, let them stand to cool and dry, and obtain a pipe insulation sleeve.

[0037] Working principle: When checking whether the air volume of the two air-spraying slots 23 is stable and uniform, the first electric telescopic cylinder 27 is extended to place the rotating piece 32 directly under the spinning slot 22. At this time, the third electric telescopic cylinder 30 is extended to place the correcting mechanism 31 directly under the rotating piece 32. At this time, the rotating piece 32 is set corresponding to the rotating piece slot 44. The second electric telescopic cylinder 28 is retracted to drive the correcting mechanism 31 to move upward as a whole. Through the inclined setting of the upper end of the first correcting block 42 and the vertical setting of the first correcting block 42, the upwardly moving first correcting block 42 can tilt the inclined rotating piece 32. The rotating piece 32 is pushed to tend to a vertical state, and the rotating piece 32 is rotated to a vertical state and slides with the rotating piece slot 44 through the tilt setting of the upper end of the second correcting block 43 and the upward movement of the second correcting block 43. At this time, the angles of the multiple rotating pieces 32 are uniformly adjusted. After the adjustment is completed, the second electric telescopic cylinder 28 is extended and the third electric telescopic cylinder 30 is retracted to move the correcting mechanism 31 to the lower end of one side of the spinneret 14. By starting the Roots blower 4, the air enters the air inlet slot 21 through the air inlet pipe 6 and is blown out through the air outlet slot 23. By observing the rotation The tilt state of the sheet 32 ​​can be used to intuitively observe and judge the stability of the air output. When the spinneret 22 is blocked and needs to be cleaned, the power supply of the electromagnet 38 is turned on. The electromagnet 38 uses its own magnetic force to magnetically attract the windshield limit mechanism 34 downward. The upper end of the windshield limit mechanism 34 releases the limit on the windshield 33. At the same time, the center limit block 39 releases the limit on the center of the windshield 33. At this time, the windshield 33 can rotate toward the spinneret 22, and the cleaning electric telescopic cylinder 25 is extended. The guide baffle 24 is pushed upward by the cleaning electric telescopic cylinder 25. The hot air inside the air inlet slot 21 is guided into the cleaning slot 40, and the hot air enters the air spray slot 23 through the guidance of the cleaning slot 40. The high-pressure hot air pressurizes and melts the polymers and impurities blocked in the air spray slot 23, thereby blowing them out, thereby effectively improving the cleaning efficiency of the air spray slot 23 and reducing the cleaning workload. When the cleaning is completed, the Roots blower 4 is turned off, the wind shield 33 naturally droops due to gravity, the power supply of the electromagnet 38 is disconnected, and the wind shield limit mechanism 34 is pushed upward by the elastic force of the spring sheet 36, thereby realizing the re-limitation of the wind shield 33.
