Description

Technical Field

[0001] This invention relates to the field of sand mill technology, specifically a sand mill for the production of anti-clogging red phosphorus flame retardant. Background Technology

[0002] Red phosphorus flame retardant, represented by red phosphorus, is a purplish-red or slightly brown amorphous powder. It is an organic, halogen-free flame retardant with excellent thermal stability, non-volatile properties, no corrosive gases, good flame retardant effect, and excellent electrical insulation. It is non-toxic, requires only a small dosage, is insoluble, and has a high melting point. The production process of red phosphorus flame retardant often involves sand milling the raw materials.

[0003] In general, when grinding materials, the material to be processed and the grinding media are put into the cylinder. Then, a rotating dispersion shaft drives a disc to stir the material and grinding media, causing them to collide and be broken down by the grinding media, thus refining the material. The material then passes through a tubular filter under negative pressure, while the tubular filter intercepts the grinding media. In existing technology, such equipment uses a real-time discharge method, that is, grinding and discharge occur simultaneously. This causes the material and grinding media to move towards the tubular filter under negative pressure. At this time, under negative pressure, some material and grinding media that cannot pass through the tubular filter will adhere to the surface of the tubular filter. Meanwhile, other material and grinding media will continue to accumulate, hindering the movement of the ground material. In addition, the material clogging the mesh will cause the actual discharge efficiency to continuously decrease, and the tubular filter cannot be cleaned and restored in time. Summary of the Invention

[0004] The purpose of this invention is to provide a grinding machine for the production of anti-clogging red phosphorus flame retardants, so as to solve the problems mentioned in the background art.

The single-machine dual-drive mechanism is connected to a material return mechanism and an internal rotating agitator. The single-machine dual-drive mechanism adjusts its power connection with the material return mechanism and the internal rotating agitator by changing the engagement state of its internal friction elements. The internal rotating agitator is used to disperse the material and grinding media inside the material return mechanism.

Both sides of the moving disc are provided with a first friction disc fixedly connected to the linkage plate. The first friction disc is rotatably connected to the adjustment frame. Two sets of second friction discs are symmetrically arranged on both sides of the driving disc. The second friction discs are rotatably installed in the clutch gearbox. One set of second friction discs is fixedly connected to a second gear ring. The second gear ring meshes with a second gear. The second gear meshes with a third gear. Both the second gear and the third gear are rotatably installed in the clutch gearbox. The third gear is fixedly connected to a fourth gear through a transmission shaft. The fourth gear is connected to the return material transfer mechanism. The other set of second friction discs is fixedly connected to a transmission head rotatably connected to the clutch gearbox. The transmission head is connected to the internal rotating agitator mechanism.

[0007] As a further improvement of the present invention: a bridge-shaped frame is fixedly installed on the top of the clutch gearbox, and a rotating support platform is fixedly connected to the bridge-shaped frame, and the rotating support platform is rotatably connected to the drive shaft.

[0008] As a further improvement of the present invention: the return material loading mechanism includes a fixed frame fixedly connected to the rotating table, the fixed frame being rotatably connected to multiple sets of grooved wheels, the multiple sets of grooved wheels jointly abutting against a sandwich cylinder, the sandwich cylinder being rotatably connected to a feeding head, the feeding head being fixedly connected to the fixed frame, the sandwich cylinder being rotatably connected to two sets of water-blocking rings, both sets of water-blocking rings being fixedly connected to control valves, the sandwich cylinder having a cooling chamber and a material loading chamber from the outside to the inside, the sandwich cylinder being fixedly connected to a third gear ring meshing with a fourth gear, the third gear having multiple sets of positioning holes opened circumferentially, the pin shaft being movably connected to the positioning holes, and the end of the sandwich cylinder away from the single-machine dual-drive mechanism being rotatably connected to the discharge straight cylinder.

[0009] As a further improvement of the present invention: the cavity inside the feeding head is a frustum-shaped structure, and the feeding end of the feeding head is movably connected to a cover.

[0010] As a further improvement of the present invention: the internal rotating agitation mechanism includes a stirring shaft rotatably connected to the feeding head, the stirring shaft is fixedly connected to a brake pad adapted to the adjustment frame, one end of the stirring shaft is fixedly connected to the transmission head, the other end of the stirring shaft is disposed in the material loading chamber, and the stirring shaft is fixedly connected to multiple sets of stirring components, which are disposed in the material loading chamber.

[0011] As a further improvement of the present invention: the stirring assembly includes a ring body fixedly connected to the stirring shaft, the ring body being fixedly connected with two sets of propulsion blades, and the ring body being fixedly connected with two sets of reverse thrust blades.

[0012] Compared with the prior art, the beneficial effects of the present invention are: When material needs to be ground, the first motor drives the first gear to rotate, which in turn drives the first gear ring to rotate. The rotating gear ring then rotates the discharge cylinder, causing the semi-circular baffle to rotate into the lower half of the discharge cylinder. The semi-circular baffle prevents the material and grinding media in the return feeding mechanism from directly entering the discharge cylinder, thus feeding the material and grinding media together into the return feeding mechanism. While restricting the return feeding mechanism, the single-machine dual-drive mechanism is also connected to the internal rotating agitator, causing the single-machine dual-drive mechanism to drive the internal rotating agitator to agitate the material and grinding media. During this process, the material in the return feeding mechanism... The material collides with the grinding media, breaking it upon impact, thus performing the grinding process. When it is necessary to separate the ground material, the single-machine dual-drive mechanism disconnects from the power connection of the internal rotating agitator, causing the internal rotating agitator to stop agitating the material and grinding media. Then, the first motor drives the first gear to rotate, which in turn drives the first gear ring to rotate. At this time, the rotating first gear ring drives the discharge cylinder to rotate, and the semi-circular baffle inside the discharge cylinder rises in height during rotation. At this time, the lower half of the space inside the discharge cylinder is connected to the inner cavity of the return material transfer mechanism. Because the discharge cylinder drives the bent pipe shell, the bent pipe shell moves away from the discharge... One end of the material straight cylinder is angled downwards. The first active telescopic rod drives the rotating table to rotate. The end of the return material transfer mechanism near the discharge straight cylinder descends, while the other end rises. The single-machine dual-drive mechanism is poweredly connected to and drives the return material transfer mechanism. At this time, under the action of gravity, the material and the grinding media slide together towards the discharge straight cylinder. Then, the material and the grinding media fall onto the screen. The drive motor drives the friction wheel to rotate, and the friction wheel drives the annular plate to rotate. During this period, due to the intermittent collision between the first and second protruding balls and the pull and reset of the first spring on the sliding sleeve, the sliding sleeve is in a state of continuous vibration. The screen vibrates, enabling it to perform vibratory screening. When it's necessary to remove the grinding media and oversized materials trapped on the screen from the curved shell, the first active telescopic rod drives the rotating table to lie flat. Then, the first motor drives the first gear to rotate, which in turn drives the first gear ring to rotate. This rotating gear ring drives the discharge cylinder to rotate, which in turn drives the curved shell to rotate upwards, causing its opening to face upwards. The vibrating screen then shakes the grinding media and oversized materials adhering to it away from the screen. Guided by the curved shell and intercepted by the semi-circular baffle, the grinding media and oversized materials are discharged separately from the grinding media outlet. This invention performs grinding by cooperating with a rotating grinding mechanism and an anti-clogging separation mechanism. After separating the qualified grinding material, the grinding media and oversized materials are separately cleaned and collected to prevent them from blocking the qualified grinding material and to avoid complete blockage of the anti-clogging separation mechanism, thus maintaining the discharge efficiency of this invention.

Detailed Implementation

[0026] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0027] Example 1, see Figures 1-12 As shown, a grinding machine for producing anti-clogging red phosphorus flame retardant includes a base 1, a control console fixedly connected to the base 1, a set of rotating tables 2 hinged to the base 1, and two sets of first active telescopic rods 3 hinged to the rotating tables 2. The first active telescopic rods 3 are hinged to the base 1. The machine also includes: A rotating abrasive mechanism 4 is connected to the rotating table 2. The rotating abrasive mechanism 4 includes a single-machine dual-drive mechanism 5 installed on the rotating table 2. The single-machine dual-drive mechanism 5 is connected to a return material transfer mechanism 6 and an internal rotating agitator 7. The single-machine dual-drive mechanism 5 adjusts the power connection state with the return material transfer mechanism 6 and the internal rotating agitator 7 by changing the engagement state of its internal friction elements. The internal rotating agitator 7 is used to disperse the material and grinding media inside the return material transfer mechanism 6. The anti-blocking separation mechanism 8 is connected to the rotating platform 2. The anti-blocking separation mechanism 8 includes a discharge cylinder 9 rotatably connected to the end face of the return material transfer mechanism 6 away from the single-machine dual-drive mechanism 5. A semi-circular baffle 10 is fixedly connected to the discharge cylinder 9. An abrasive discharge outlet 11 is opened on the discharge cylinder 9. A sealing frame 12 is rotatably connected to the outer wall of the discharge cylinder 9. The sealing frame 12 is fixedly connected to the rotating platform 2. A bent pipe shell 13 is fixedly connected to the discharge cylinder 9. A sliding sleeve 14 is slidably connected to the bent pipe shell 13. A first spring is fixedly connected to the sliding sleeve 14. The first spring is fixedly connected to the bent pipe shell 13. A screen is fixedly connected to the sliding sleeve 14. 15. The sliding sleeve 14 is fixedly connected to a first protruding ball 17. The bent tube shell 13 is rotatably connected to an annular plate 18 that periodically cooperates with the first protruding ball 17. The annular plate 18 is fixedly connected to multiple sets of second protruding balls 19. The bent tube shell 13 is fixedly connected to a drive motor 20. The output shaft of the drive motor 20 is fixedly connected to a friction wheel 21 that abuts against the annular plate 18. The rotating table 2 is fixedly connected to a first motor 22. The output shaft of the first motor 22 is fixedly connected to a first gear 23. The first gear 23 meshes with a first gear ring 58. The first gear ring 58 is fixedly connected to the discharge straight cylinder 9.

[0028] When material needs to be ground, the first motor 22 drives the first gear 23 to rotate, and the first gear 23 drives the first gear ring 58 to rotate. At this time, the rotating first gear ring 58 drives the discharge cylinder 9 to rotate, so that the semi-circular baffle 10 rotates into the lower half of the space inside the discharge cylinder 9. The semi-circular baffle 10 is used to prevent the material and grinding media in the return feeding mechanism 6 from directly entering the discharge cylinder 9, and to feed the material and grinding media into the return feeding mechanism 6 together. While restricting the return feeding mechanism 6, the single-machine dual-drive mechanism 5 is poweredly connected to the internal rotating agitator 7, so that the single-machine dual-drive mechanism 5 drives the internal rotating agitator 7 to agitate the material and grinding media. During this period, the material in the return feeding mechanism 6 and the grinding media are mixed together. The grinding media collide with each other, and the material is broken by the impact, thus performing the grinding operation. When it is necessary to separate the ground material, the single-machine dual-drive mechanism 5 disconnects from the power connection with the inner rotating agitator 7, causing the inner rotating agitator 7 to stop agitating the material and grinding media. Then, the first motor 22 drives the first gear 23 to rotate, and the first gear 23 drives the first gear ring 58 to rotate. At this time, the rotating first gear ring 58 drives the discharge cylinder 9 to rotate. The semi-circular baffle 10 inside the discharge cylinder 9 rises in height during rotation. At this time, the lower half of the space inside the discharge cylinder 9 is connected to the inner cavity of the return material transfer mechanism 6. At this time, due to the action of the discharge cylinder 9 on the bent tube shell 13, the end of the bent tube shell 13 away from the discharge cylinder 9 is inclined downward. The first active telescopic rod 3 drives the rotating table 2 to rotate. The end of the return material transfer mechanism 6 near the discharge cylinder 9 descends, and the other end of the return material transfer mechanism 6 rises. The single-machine dual-drive mechanism 5 is powered by the return material transfer mechanism 6 and drives the return material transfer mechanism 6. At this time, under the action of gravity, the material and the grinding media slide together towards the discharge cylinder 9. Then the material and the grinding media fall onto the screen 15. The drive motor 20 drives the friction wheel 21 to rotate. The friction wheel 21 drives the annular plate 18 to rotate. During this period, due to the intermittent collision between the first protruding ball 17 and the second protruding ball 19 and the pull and reset of the first spring on the sliding sleeve 14, the sliding sleeve 14 is in a state of continuous vibration. During this period, the sliding sleeve 14 drives the screen 15 to vibrate, making When the screen 15 is vibrating and screening, and when it is necessary to remove the grinding media and oversized materials intercepted on the screen 15 from the bent tube shell 13, the first active telescopic rod 3 drives the rotating table 2 to be placed horizontally. Then, the first motor 22 drives the first gear 23 to rotate, and the first gear 23 drives the first gear ring 58 to rotate. At this time, the rotating first gear ring 58 drives the discharge cylinder 9 to rotate, and the discharge cylinder 9 drives the bent tube shell 13 to rotate upward, so that the opening of the bent tube shell 13 faces upward. At this time, the vibrating screen 15 shakes the grinding media and oversized materials attached to the screen 15 away from the screen 15. Under the guidance of the bent tube shell 13 and the interception of the semi-circular baffle 10, the grinding media and oversized materials are discharged separately from the grinding discharge outlet 11 from the bent tube shell 13.This invention performs sand milling by cooperating with the rotating abrasive mechanism 4 and the anti-clogging separation mechanism 8. After separating the qualified sand milled material, the grinding media and excessively large materials are cleaned and collected separately to prevent them from blocking the qualified sand milled material and to prevent the anti-clogging separation mechanism 8 from being completely blocked, thereby maintaining the discharge efficiency of this invention.

[0029] In one embodiment, the single-machine dual-drive mechanism 5 includes a second motor 24 fixedly connected to the rotating platform 2. The rotating platform 2 is fixedly connected to a clutch gearbox 25. The second motor 24 is coaxially fixedly connected to a prism 26. The plane intercepted by the prism 26 along the direction perpendicular to the central axis is polygonal. The prism 26 is slidably connected to an active disc 27 disposed within the clutch gearbox 25. The clutch gearbox 25 is fixedly connected to a cylinder 28. The telescopic end of the cylinder 28 is fixedly connected to an adjusting frame 29 slidably connected to the clutch gearbox 25. The adjusting frame 29 is fixedly connected to two sets of pins 30 movably connected to the return material transfer mechanism 6. The active disc 27 is rotatably connected to the adjusting frame 29. Multiple sets of spring grooves 31 are formed circumferentially within the active disc 27. A second spring is fixedly installed within each spring groove 31. The second spring is fixedly connected to a linkage that is slidably installed within the spring groove 31. Plate 32, the active plate 27 has a first friction plate 33 fixedly connected to the linkage plate 32 on both sides. The first friction plate 33 is rotatably connected to the adjustment frame 29. Two sets of second friction plates 34 are symmetrically arranged on both sides of the active plate 27. The second friction plates 34 are rotatably installed in the clutch gearbox 25. One set of second friction plates 34 is fixedly connected to a second gear ring 35. The second gear ring 35 is meshed with a second gear 36. The second gear 36 is meshed with a third gear 37. The second gear 36 and the third gear 37 are both rotatably installed in the clutch gearbox 25. The third gear 37 is fixedly connected to a fourth gear 39 through a transmission shaft 38. The fourth gear 39 is connected to the return material transfer mechanism 6. The other set of second friction plates 34 is fixedly connected to a transmission head 40 rotatably connected to the clutch gearbox 25. The transmission head 40 is connected to the internal rotating agitator 7. Under normal circumstances, the first friction disc 33 and the second friction disc 34 are separated from each other, and the pin 30 is inserted into the return material transfer mechanism 6 to prevent the return material transfer mechanism 6 from rotating freely. When the single-machine dual-drive mechanism 5 needs to drive the internal rotating agitator 7, the cylinder 28 drives the adjusting frame 29 to move, so that the pin 30 is further inserted into the return material transfer mechanism 6. The moving adjusting frame 29 drives the active disc 27 to move towards the transmission head 40, so that the second friction disc 34, which is fixedly connected to the transmission head 40, abuts against a set of first friction discs 33. The second motor 24 drives the prism 26 to rotate, and the rotating prism 26 drives the... When the driving disk 27 rotates, it applies pressure to the second spring through the spring groove 31. The second spring, in turn, applies pressure to the linkage plate 32 through the spring groove 31, causing the linkage plate 32 to drive the first friction disk 33 to rotate. At this moment, the frictional force applied by the first friction disk 33 to the second friction disk 34 is insufficient to make the second friction disk 34 rotate at the same angular velocity as the driving disk 27. This creates a difference in rotational stroke between the second friction disk 34 and the driving disk 27, causing the linkage plate 32 to further compress the second spring. At this point, the first friction disk 33 and the driving disk 27 are misaligned circumferentially.During this period, the supporting force exerted by the compressed second spring on the linkage plate 32 increases, further increasing the rotational angular velocity of the first friction disc 33 and the second friction disc 34, thereby accelerating the rotation of the first friction disc 33. The first friction disc 33 rubs against the second friction disc 34, thus providing greater acceleration to the second friction disc 34. When the rotational angular velocity of the first friction disc 33 and the second friction disc 34 is the same as the rotational angular velocity of the driving disc 27, the second spring is compressed to its maximum value. Then, during the extension of the second spring, the first friction disc 33 and the second friction disc 34 first accelerate and then decelerate until the rotational angular velocities of the first friction disc 33, the second friction disc 34, and the driving disc 27 are the same. The rotating second friction disc 34 drives the transmission head 40 to rotate. When the internal rotating agitator 7 needs to be driven by the single-machine dual-drive mechanism 5 to drive the return material transfer mechanism 6, the cylinder 28 drives the adjusting frame 29 to move, causing the pin 30 to disengage from the return material transfer mechanism 6, thereby releasing the limit on the return material transfer mechanism 6. During this period, the moving adjusting frame 29 drives the drive disc 27 to move away from the transmission head 40. The drive disc 27 slides relative to the prism 26. Another set of first friction discs 33 abuts against another set of second friction discs 34. The second motor 24 drives the drive disc 27 to rotate through the prism 26. The drive disc 27 applies pressure to the second spring through the spring groove 31. The second spring applies pressure to the linkage plate 32 through the spring groove 31, causing the linkage plate 32 to drive the first friction disc 33 to rotate. At this time, the first friction disc 33 applies pressure to the second friction disc 34. The frictional force applied by disc 34 is insufficient to make the second friction disc 34 and the driving disc 27 rotate at the same angular velocity, thus creating a stroke difference between the second friction disc 34 and the driving disc 27. This causes the linkage plate 32 to further compress the second spring. At this time, the first friction disc 33 and the driving disc 27 are misaligned circumferentially. During this period, the supporting force exerted by the compressed second spring on the linkage plate 32 increases, further increasing the rotational angular velocity of the first friction disc 33 and the second friction disc 34, thereby accelerating the rotation of the first friction disc 33. The first friction disc 33 rubs against the second friction disc 34, thus providing greater acceleration to the second friction disc 34. In the first instance, the rotational angular velocity of the first friction disc 33 and the second friction disc 34 is the same as the rotational angular velocity of the driving disc 27. At this time, the second spring is compressed to its maximum value. Then, during the extension of the second spring, the first friction disk 33 and the second friction disk 34 first accelerate and then decelerate until the rotational angular velocities of the first friction disk 33, the second friction disk 34, and the driving disk 27 are the same. During this period, the second friction disk 34 drives the second gear ring 35 to rotate. The rotating second gear ring 35 is transmitted through the second gear 36 and the third gear 37, so that the transmission shaft 38 rotates and drives the fourth gear 39 to rotate. The rotating fourth gear 39 provides driving force for the return material transfer mechanism 6. The single-machine dual-drive mechanism 5 selectively provides power to the return material transfer mechanism 6 or the internal rotating agitator mechanism 7 through autonomous control, and ensures the smoothness of transmission, avoiding sudden acceleration and excessive impact from friction.This also avoids excessive friction between the first friction disc 33 and the second friction disc 34 due to speed difference, thereby extending the service life of the single-machine dual-drive mechanism 5. It also allows a second motor 24 to provide power to the return material transfer mechanism 6 and the internal rotating agitator 7 separately, eliminating the need for a separate power source.

[0030] In one embodiment, a bridge-shaped frame 41 is fixedly mounted on the top of the clutch gearbox 25. A rotating support platform 42 is fixedly connected to the bridge-shaped frame 41 and rotatably connected to the drive shaft 38. The rotating support platform 42 provides rotatable support to the drive shaft 38, preventing it from bending.

[0031] In one embodiment, the return loading mechanism 6 includes a fixed frame 43 fixedly connected to the rotating table 2. The fixed frame 43 is rotatably connected to multiple sets of grooved wheels 44, which together abut against a core cylinder 45. The core cylinder 45 is rotatably connected to a feeding head 46, which is fixedly connected to the fixed frame 43. The core cylinder 45 is rotatably connected to two sets of water-blocking rings 47, each of which is fixedly connected to a control valve 16. The control valve 16 is used to connect to an external coolant circulation device. The core cylinder 45 has a cooling chamber 48 and a loading chamber 49 arranged from the outside to the inside. The core cylinder 45 is fixedly connected to a third gear ring 50 that meshes with a fourth gear 39. The third gear ring 50 has multiple sets of positioning holes 51 circumferentially opened on its upper edge. The pin 30 is movably connected to the positioning holes 51. The end of the core cylinder 45 away from the single-machine dual-drive mechanism 5 is rotatably connected to the discharge straight cylinder 9. After the pin 30 disengages from the positioning hole 51, the third gear ring 50 drives the sandwich cylinder 45 to rotate under the drive of the rotating fourth gear 39. The grooved wheel 44 provides support for the rotating sandwich cylinder 45. The sandwich cylinder 45 rotates relative to the feeding head 46. When the sandwich cylinder 45 is tilted, the rotating sandwich cylinder 45 assists in the movement of the material and grinding media. By rotating the sandwich cylinder 45, the contact position between the sandwich cylinder 45 and the deposited material changes each time the grinding operation is performed, so as to ensure that the sandwich cylinder 45 is worn evenly. During the sand milling process, the pin 30 is inserted into the positioning hole 51 to restrict the rotation of the third gear ring 50, thereby restricting the rotation of the sandwich cylinder 45. Then, the material and sand milling media are fed into the sandwich cylinder 45 through the feeding head 46. The coolant circulation equipment circulates the coolant to the cooling chamber 48 through the control valve 16 to cool the material and sand milling media in the loading chamber 49 and prevent the material from overheating. When the sandwich cylinder 45 rotates, the water baffle ring 47 rotates relative to the sandwich cylinder 45 to maintain the connection between the cooling chamber 48 and the coolant circulation equipment.

[0032] In one embodiment, the cavity inside the feeding head 46 is a frustum-shaped structure, and the cavity inside the feeding head 46 is connected to the loading cavity 49. A cover 52 is movably connected to the feeding end of the feeding head 46. By setting the cavity inside the feeding head 46 to a frustum-shaped structure, the material and grinding media entering the feeding head 46 can slide into the loading cavity 49.

[0033] In one embodiment, the internal agitation mechanism 7 includes a stirring shaft 53 rotatably connected to the feeding head 46. The stirring shaft 53 is fixedly connected to a brake pad 59 adapted to the adjusting frame 29. One end of the stirring shaft 53 is fixedly connected to the transmission head 40, and the other end is disposed within the material loading chamber 49. Multiple sets of stirring components 54 are fixedly connected to the stirring shaft 53 and disposed within the material loading chamber 49. The rotating transmission head 40 drives the stirring shaft 53 to rotate, which in turn drives the stirring components 54 to rotate, thereby agitating the material and grinding media. When the adjusting frame 29 abuts against the brake pad 59, it restricts the rotation of the stirring shaft 53, preventing the stirring components 54 from rotating when the sandwich cylinder 45 rotates.

[0034] Example 2, based on Example 1, see [link / reference] Figure 3 and Figure 4 The stirring assembly 54 includes a ring 55 fixedly connected to the stirring shaft 53. Two sets of propulsion blades 56 and two sets of counter-propulsion blades 57 are fixedly connected to the ring 55. When the stirring shaft 53 rotates, the ring 55 rotates, causing the propulsion blades 56 and counter-propulsion blades 57 to rotate. This results in the propulsion blades 56 pushing the material in the opposite direction to the counter-propulsion blades 57, thereby simultaneously pushing the material and grinding media laterally while performing circumferential stirring. This ensures sufficient impact between the grinding media and the material, and facilitates homogenization of the material and grinding media.

[0035] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
