Description

Technical Field

[0001] The invention belongs to the technical field of sand flour production and manufacturing, and in particular relates to sand flour milling equipment. Background Art

[0002] Sand flour is a specially treated high molecular weight polypropylene wax. Sand flour feels smooth, has a narrow particle size distribution range, is uniform in particle size, has stable chemical properties, is UV-resistant, light-resistant, heat-resistant, acid-resistant, and has a wide range of applications. It is widely used in hardware paint, furniture paint, glass paint, plastic paint, sand surface ink, and screen printing ink. Sand flour is surface treated, easy to disperse, and has good compatibility with resin. When used in water-based systems, it will not cause floating, precipitation, or whitening.

[0003] The manufacturing process of sand flour is as follows: polypropylene wax is added into 95 degrees Celsius xylene to dissolve and continuously stirred for 50 minutes to form a solution, and then sodium dodecyl sulfate is added into 95 degrees Celsius water to dissolve, and then the aqueous solution of sodium dodecyl sulfate is mixed with the xylene solution of polypropylene wax and continuously stirred for one hour at 95 degrees Celsius to form a stable emulsion, and then the emulsion is cooled to below 35 degrees Celsius with cold water so that the small droplets in the emulsion solidify into solid particles, and then the solid particles in the liquid are filtered out with a filtering device and stirred and washed with ethanol, and the solid particles washed with ethanol are filtered again and dried to form sand flour.

[0004] The manufacturing process of the above-mentioned sand flour involves a variety of equipment, the layout and commissioning of the equipment is time-consuming and labor-intensive, the efficiency is low and the layout space is large.

[0005] The present invention optimizes the design of equipment involved in the sand flour manufacturing process into a vertical layout, effectively saves equipment layout space and simultaneously performs integrated optimization design on parts, effectively reduces equipment cost and makes the equipment more miniaturized. Summary of the invention

[0006] Based on this, it is necessary to provide a sand flour powder making device for the problems existing in the current sand flour powder making device. The feeding component in the present invention can quantitatively add solid polypropylene wax material to the dissolving material emulsifying component through the alternating movement of the two partitions in the slot on the feeding pipe, which effectively ensures the solid-liquid ratio in the dissolving material emulsifying component. The dissolving material emulsifying component in the present invention integrates the two functions of dissolving polypropylene wax and stirring and mixing active water with polypropylene wax solution to form an emulsion. At the same time, the filtering and drying component in the present invention and the filtering, washing and drying functions of sand flour are integrated, which effectively reduces the number of related process equipment, thereby reducing the production cost of the equipment and making the equipment more miniaturized, saving equipment layout space. The feeding component, dissolving material emulsifying component, cooling component, heat exchange component and filtering and drying component in the present invention are distributed vertically rather than distributed in sequence in the horizontal direction, which effectively saves the layout space of the equipment in the factory. The heat exchange component in the present invention uses the heat released by the solution entering the cooling component from the dissolving material emulsifying component to effectively dry the sand flour that reaches the filtering and drying component and is filtered and washed, which has an energy-saving effect.

[0045] The feeding component 200 in the present invention can quantitatively add solid polypropylene wax material to the dissolving emulsification component 300 through the alternating movement of the two partitions 206 in the slot 203 on the feeding pipe 202, effectively ensuring the solid-liquid ratio in the dissolving emulsification component 300. The dissolving emulsification component 300 in the present invention integrates the two functions of dissolving polypropylene wax and stirring and mixing active water with the polypropylene wax solution to form an emulsion. At the same time, the filtering and drying component 600 in the present invention and the filtering, washing and drying functions of sand flour are integrated, which effectively reduces the number of related process equipment, thereby reducing the production cost of the equipment and making the equipment more miniaturized, saving equipment layout space. The feeding component 200, dissolving emulsification component 300, cooling component 400, heat exchange component 500 and filtering and drying component 600 in the present invention are distributed vertically rather than distributed in sequence in the horizontal direction, which effectively saves the layout space of the equipment in the factory. The heat exchange component 500 of the present invention utilizes the heat released by the solution entering the cooling component 400 from the solvent emulsification component 300 to effectively dry the sand flour that reaches the filtering and drying component 600 and is filtered and washed, thereby achieving energy-saving effect.

[0046] The operation process of the present invention is as follows: In the initial state, the two partitions 206 in the feeding assembly 200 are both in a closed state with respect to the feeding pipe 202, the second connecting hole 309 on the wall of the second cylinder 307 in the dissolving emulsifying assembly 300 is closed by the baffle strip 316, the first connecting hole 308 at the bottom of the second cylinder 307 is closed by the circular plate 317, and the first valve 324 is closed. The third valve 415 in the cooling assembly 400 is closed. The fifth valve 509 in the heat exchange assembly 500 is closed. The sixth valve 608 in the filtering and drying assembly 600 is closed, and the valve plug 616 is closed to the lower end of the inverted cone 604.

[0047] When the sand flour is to be produced by the present invention, the polypropylene wax particles are first filled into the hopper 201, and then the first motor 210 is started. The first motor 210 drives the two partitions 206 to slide in opposite directions through the first rotating shaft 209, the first gear 208, and the two first racks 207. The upper partition 206 is opened and the lower partition 206 is kept closed. The material in the hopper 201 fills the space between the two partitions 206 under the action of its own weight. Then, the first motor 210 is started in the reverse direction. The first motor 210 drives the two partitions 206 to perform a reset movement through a series of transmissions. The two partitions 206 first close the discharge pipe 202 at the same time. As the two partitions 206 continue to move, the upper partition 206 is kept closed and the lower partition 206 is opened. The material between the two partitions 206 falls into the first cylinder 301 through the discharge pipe 202 under the action of its own weight.

[0048] After the material enters the first cylinder 301, the first liquid pump 320 is started, and the first liquid pump 320 quantitatively delivers the organic solvent to the first cylinder 301 through the first feeding pipe 319. Then, the fourth motor 701 is started, and the fourth motor 701 drives the first propeller blade 305 to rotate through the fifth shaft 702, the fourth gear 703, the fifth gear 704, the sixth shaft 705, the sixth gear 706, the seventh gear 707 and the second shaft 304. The first propeller blade 305 drives the mixture of polypropylene wax and organic solvent in the first cylinder 301 to flip and stir. At the same time, the electric heating layer 302 heats the organic solution in the first cylinder 301 to 95 degrees Celsius. Under the temperature environment of 95 degrees Celsius, the first propeller blade 305 continuously stirs the mixture of polypropylene wax and organic solvent for 50 minutes to make the polypropylene wax completely dissolved in the organic solvent.

[0049] While the first propeller blade 305 is stirring the mixture of polypropylene wax and organic solvent, the second liquid pump 322 is started to inject a certain amount of active water into the second cylinder 307 through the second feeding pipe 321. The active water in the first cylinder 301 is heated to 95 degrees Celsius during the stirring of the mixture of polypropylene wax and organic solvent. When the mixture of polypropylene wax and organic solvent is completely dissolved, the second motor 315 is started. The second motor 315 drives the second ring 312, the baffle strip 316 and the circular plate 317 to rotate synchronously by a certain amplitude through the second gear 314 and the ring gear 313, so that the baffle strip 316 opens the second connecting hole 309 on the second cylinder 307 and the third connecting hole 318 on the circular plate 317 is opposite to the first connecting hole 308 at the bottom of the second cylinder 307 and opens to the first connecting hole 308.

[0050] The mixed liquid outside the second cylinder 307 rotates driven by the first propeller blade 305 and enters the second cylinder 307 under the guidance of the first guide plate 310. The active water in the second cylinder 307 enters the first cylinder 301 under the guidance of the second guide plate 311. At the same time, the liquid inside and outside the second cylinder 307 moves interactively through the first connecting hole 308 at the bottom of the second cylinder 307 and the third connecting hole 318 on the circular plate 317, so that the organic solvent solution of polypropylene wax and the active water are fully and evenly mixed.

[0051] When the two liquids in the first cylinder 301 and the second cylinder 307 are fully stirred and mixed at a temperature of 95 degrees Celsius for one hour, an emulsion is formed.

[0052] Next, the fourth motor 701 is stopped, the first propeller blade 305 stops stirring, the first valve 324 is opened, the emulsion in the first cylinder 301 and the second cylinder 307 enters the third cylinder 401 through the first discharge pipe 323, the first valve 324 is closed and the fourth motor 701 is started, the fourth motor 701 drives the second propeller blade 405 to rotate through the fifth shaft 702, the eighth gear 708, the ninth gear 709, the seventh shaft 710, the tenth gear 712, the eleventh gear 713 and the third shaft 404, and continuously turns and stirs the emulsion in the third cylinder 401, and at the same time, the third liquid pump 408 is started, and the third liquid pump 408 pumps cold water into the vortex channel 406 through the water inlet pipe 407, and the cold water is spun in the vortex channel 406 for a long distance. The emulsion stirred by the second propeller blade 405 is fully in contact with the outer wall of the vortex channel 406 and is fully cooled by the cold water in the vortex channel 406. The cold water in the vortex channel 406 is heated and continuously moves to the second three-way valve 411 through the first drain pipe 409. If the temperature sensor 410 on the first drain pipe 409 detects that the water temperature flowing through is greater than 50 degrees Celsius, the second valve 411 opens the third drain pipe 413 and closes the second drain pipe 412. If the temperature sensor 410 detects that the water temperature flowing through is less than 50 degrees Celsius, the second valve 411 closes the third drain pipe 413 and opens the second drain pipe 412. The water less than 50 degrees Celsius reaches the heat dissipation tower through the second drain pipe 412 for heat dissipation and cooling and recycling. As the emulsion in the third cylinder 401 is continuously cooled by the cold water in the vortex channel 406, the temperature of the water in the first drain pipe 409 gradually decreases from greater than 50 degrees Celsius to less than 50 degrees Celsius.

[0053] When the water with a temperature greater than 50 degrees Celsius enters the fourth cylinder 501, the air pump 506 is turned on to pump dry air into the spiral tube 504 through the air inlet pipe 505. The dry air flowing through the spiral tube 504 is heated by the hot air entering the fourth cylinder 501 and enters the first exhaust pipe 507. If the temperature of the dry air in the spiral tube 504 does not meet the requirement, the electric heater 508 is turned on to heat the dry air passing through the first exhaust pipe 507.

[0054] After the temperature of the water in the fourth cylinder 501 is lowered, the fourth valve 503 is opened to discharge the water through the fourth drain pipe 502 to the heat dissipation tower for heat dissipation, cooling and recycling.

[0055] When the emulsion in the third cylinder 401 is cooled to below 35 degrees, the droplets in the emulsion solidify into sand flour particles. Then, the fourth motor 701 is stopped, the third valve 415 is opened, and the mixture of sand flour and water in the third cylinder 401 is discharged into the inverted cone cylinder 604 through the second discharge pipe 414. At the same time, Then, the fourth motor 701 is started, and the fourth motor 701 drives the spiral strip 619 and the scraper 620 to rotate through the fifth shaft 702, the twelfth gear 714, the thirteenth gear 715, the eighth shaft 716, the fourteenth gear 717, the fifteenth gear 718, the fourth shaft 617 and the second connecting frame 618. The spiral strip 619 and the scraper 620 stir the mixture of sand flour and water entering the inverted cone 604, so that the water passes through the inverted cone 604. The filter hole 606 on the wall quickly enters the liquid chamber 605, the sixth valve 608 is opened, and the water entering the liquid chamber 605 is discharged through the third discharge pipe 607, the spiral strips 619 scrape off the sand and flour attached to the inner wall of the inverted cone cylinder 604, and the scraper 620 scrapes off the sand and flour attached to the conical surface of the upper end of the valve plug 616 to avoid clogging of the filter hole 606 on the inner wall of the inverted cone cylinder 604, ensuring that the water in the inverted cone cylinder 604 can continuously and smoothly enter the liquid chamber 605 to complete the filtering of the sand and flour.

[0056] When the sand flour in the inverted cone cylinder 604 is filtered, the spiral strips 619 are still rotated to make the sand flour in the inverted cone cylinder 604 continue to flip, and the fourth liquid pump 603 is started. The fourth liquid pump 603 pumps a fixed amount of ethanol into the inverted cone cylinder 604 through the third feeding pipe 602. The ethanol entering the inverted cone cylinder 604 washes the sand flour under the flipping of the spiral strips 619, and the ethanol is discharged through the filter hole 606, the liquid cavity 605 and the third discharge pipe 607.

[0057] When the sand flour in the inverted cone cylinder 604 is washed, the fourth liquid pump 603 is stopped and the injection of ethanol into the inverted cone cylinder 604 is stopped. Then, the sixth valve 608 is closed and the fifth valve 509 is opened. The heated dry air in the first exhaust pipe 507 enters the inverted cone cylinder 604 through the third discharge pipe 607, the liquid cavity 605 and the filter hole 606 to dry the inverted sand flour. The pressure relief hole at the top of the fifth cylinder 601 continues to exhaust and relieve pressure to the outside.

[0058] When the sand flour in the inverted cone 604 is completely dry, the fifth valve 509 is closed and the third motor 615 is started. The third motor 615 drives the valve plug 616 to move downward and open the bottom of the inverted cone 604 through the third gear 614, the second rack 613 and the guide rod 612. At the same time, the fourth motor 701 is driven in the reverse direction. The fourth motor 701 drives the spiral strips 619 to rotate in the reverse direction through a series of transmissions and pushes the dried sand flour in the inverted cone 604 into the silo 609. When all the sand flour enters the silo 609, the fourth motor 701 is stopped, and the sand flour entering the silo 609 is discharged through the fourth discharge pipe 611 under the action of its own weight for collection.

[0059] When the sand flour in the silo 609 is completely discharged, the third motor 615 is started to drive the valve plug 616 to return to the bottom of the inverted cone 604 and close.
