Description

Technical Field

[0001] This utility model relates to the field of new materials technology, and in particular to a composite flame retardant tableting and granulation equipment. Background Technology

[0002] Flame retardants are additives that prevent polymer materials from igniting or inhibit the spread of flame. The most commonly used and important flame retardants are compounds of phosphorus, bromine, chlorine, antimony, and aluminum. They are incorporated into composite materials during the processing of composite materials, are easy to use, have stable performance, and provide long-lasting flame retardancy.

[0003] Currently, during the granulation process of composite flame retardants, the particles and raw materials fall together in the granulation structure, resulting in poor recycling of the falling raw materials. Therefore, there is an urgent need to design a composite flame retardant tableting and granulation equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing a composite flame retardant tableting and granulation equipment.

[0005] This utility model is achieved through the following technical solution: a composite flame retardant tableting and granulation equipment, including a machine housing, a power roller rotatably arranged in the upper part of the machine housing, an auxiliary roller arranged behind the power roller, one end of the power roller connected to the output shaft of a motor, the motor mounted on a frame, the frame connected to the outer wall of the machine housing, a sieve plate inclinedly arranged below the power roller and the auxiliary roller, a vibration mechanism symmetrically arranged at both ends of the sieve plate, an inner end of a material flow plate inclinedly arranged above the power roller, and an outer end of the material flow plate arranged outside the material inlet.

[0006] As a further improvement to the above scheme, a plurality of truncated cone holes are evenly distributed on the outer curved surface of the power roller. A support plate is movably provided at the bottom of the truncated cone hole. The lower end of the support plate is connected to a connecting rod. The connecting rod is movably provided in a rod hole, which is provided through the lower part of the truncated cone hole. A spring is fitted on the connecting rod. The end of the connecting rod away from the support plate is connected to a nut baffle.

[0007] Flame retardant material is filled into the cone-shaped hole and squeezed into a sheet by the convex cone to obtain a flame retardant sheet. The flame retardant sheet is pushed upward by the support plate in the cone-shaped hole, causing the flame retardant sheet to detach from the cone-shaped hole. The support plate is subjected to the force of spring one, and spring one is supported by the connecting rod in the rod hole, making the extension and contraction of spring one smoother.

[0008] As a further improvement to the above solution, several convex cones are evenly distributed on the outer curved surface of the auxiliary roller, and the convex cones match the cone holes.

[0009] Through the matching convex cone and cone hole, the auxiliary roller is driven to rotate through the gear pair during the rotation of the power roller, so that the convex cone squeezes the material in the cone hole, and the flame retardant is squeezed into sheets.

[0010] As a further improvement to the above solution, the vibration mechanism includes a base plate, which is connected to the inner wall of the housing. A support column is provided through the base plate, the upper end of the support column is connected to the lower surface of the screen plate, and two springs are sleeved on the support column between the base plate and the screen plate. A stop cap is connected to the lower end of the support column.

[0011] Supported by the vibration mechanism, the screen plate is subjected to the gravity of the flame-retardant sheet and loose material falling from above. Supported by spring two and the self-vibration of the device, the screen plate filters the flame-retardant sheet and loose material, causing the loose material to fall through the small screen holes and the large screen plate.

[0012] As a further improvement to the above solution, the upper part of the sieve plate is provided with small sieve holes, and the lower part of the sieve plate is provided with large sieve holes.

[0013] Small sieves filter loose materials, while large sieves filter fine particles.

[0014] As a further improvement to the above scheme, the ends of the power roller and the auxiliary roller away from the motor are fitted with a meshing gear pair; the power of the motor rotation is transmitted from the power roller to the auxiliary roller through the meshing gear pair, making the relative rotation of the power roller and the auxiliary roller smoother and avoiding the obstruction and delay of the rotation of the auxiliary roller.

[0015] As a further improvement to the above solution, a slag removal port is provided on the lower side wall of the housing;

[0016] Clean the debris and particles that have fallen off the sieve plate through the slag removal port.

[0017] As a further improvement to the above solution, a particle collection port is provided on the side wall of the casing away from the feed inlet;

[0018] The falling flame retardant particles roll on the sieve plate. The rolling action removes any defects in the flame retardant particles, ensuring their quality and preventing the accumulated particles from breaking apart.

[0019] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. Material is fed into the power roller through the material feeding plate. The material filled in the cone hole is squeezed into a sheet by the rolling of the power roller. Under the rotation of the power roller and the auxiliary roller, the cone disengages from the cone hole. The flame retardant sheet is pushed by the spring to the support plate, causing the flame retardant sheet to fall off the cone hole and onto the screen plate. The screen plate filters the broken particles and loose materials. The intact flame retardant sheet rolls off the screen plate and is collected from the particle collection port, while the loose materials and broken particles are cleaned and collected from the slag removal port. In addition, the screen plate is further aided in filtering loose materials and broken particles by the self-vibration of the vibration mechanism. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1 to 6 As shown, a composite flame retardant tableting and granulation equipment includes a housing 1. A power roller 2 is rotatably arranged in the upper part of the housing 1, and an auxiliary roller 3 is arranged behind the power roller 2. One end of the power roller 2 is connected to the output shaft of a motor 4. The motor 4 is mounted on a frame 5, and the frame 5 is connected to the outer wall of the housing 1. A screen plate 8 is inclinedly arranged below the power roller 2 and the auxiliary roller 3. Vibration mechanisms 9 are symmetrically arranged at both ends of the screen plate 8. An inner end of a material flow plate 7 is inclinedly arranged above the power roller 2, and the outer end of the material flow plate 7 is arranged outside the material inlet 6.

[0028] As a further improvement to the above scheme, a plurality of frustoconical holes 21 are evenly distributed on the outer curved surface of the power roller 2. A support plate 22 is movably disposed at the bottom of the frustoconical hole 21. The lower end of the support plate 22 is connected to a connecting rod 23. The connecting rod 23 is movably disposed in a rod hole 26. The rod hole 26 is disposed through the lower part of the frustoconical hole 21. A spring 24 is fitted on the connecting rod 23. The end of the connecting rod 23 away from the support plate 22 is connected to a nut baffle 25.

[0029] Flame retardant material is filled into the frustum hole 21 and is compressed into a sheet by the convex frustum 31 to obtain a flame retardant sheet. The flame retardant sheet is pushed upward by the support plate 22 in the frustum hole 21, causing the flame retardant sheet to detach from the frustum hole 21. The support plate 22 is subjected to the force of the spring 24, and the spring 24 is supported by the connecting rod 23 in the rod hole 26, making the extension and contraction of the spring 24 smoother.

[0030] As a further improvement to the above scheme, a plurality of convex cones 31 are evenly distributed on the outer curved surface of the auxiliary roller 3, and the convex cones 31 are matched with the cone holes 21.

[0031] Through the matching convex cone 31 and cone hole 21, the auxiliary roller 3 is driven to rotate through the gear pair 12 during the rotation of the power roller 2, so that the convex cone 31 squeezes the material in the cone hole 21, and the flame retardant is squeezed into sheets.

[0032] As a further improvement to the above solution, the vibration mechanism 9 includes a base plate 91, which is connected to the inner wall of the housing 1. A support column 92 is provided through the base plate 91. The upper end of the support column 92 is connected to the lower surface of the sieve plate 8. A spring 93 is sleeved on the support column 92 between the base plate 91 and the sieve plate 8. The lower end of the support column 92 is connected to a stop cap.

[0033] Supported by the vibration mechanism 9, the sieve plate 8 is subjected to the gravity of the flame-retardant sheet and loose material falling from above. Supported by the second spring 93 and the self-vibration of the device, the sieve plate 8 filters the flame-retardant sheet and loose material, causing the loose material to fall from the small sieve hole 81 and the large sieve plate 8.

[0034] As a further improvement to the above scheme, the upper part of the sieve plate 8 is provided with small sieve holes 81, and the lower end of the sieve plate 8 is provided with large sieve holes 82.

[0035] Use the small sieve aperture 81 to filter loose materials and the large sieve aperture 82 to filter particles.

[0036] As a further improvement to the above scheme, the ends of the power roller 2 and the auxiliary roller 3 away from the motor 4 are fitted with a meshing gear pair 12; the power of the motor 4 is transmitted from the power roller 2 to the auxiliary roller 3 through the meshing gear pair 12, so that the relative rotation of the power roller 2 and the auxiliary roller 3 is smoother, and the obstruction and delay of the rotation of the auxiliary roller 3 are avoided.

[0037] As a further improvement to the above solution, a slag removal port 11 is provided on the lower side wall of the housing 1;

[0038] The debris and particles that have fallen off the screen plate 8 are cleaned through the slag removal port 11.

[0039] As a further improvement to the above scheme, a particle collection port 14 is provided on the side wall of the housing 1 away from the feed port 6;

[0040] The falling flame retardant particles roll on the sieve plate 8. The rolling action removes any defects in the flame retardant particles, ensuring their quality and preventing the accumulated particles from breaking apart.

[0041] The working principle of a composite flame retardant tableting and granulation equipment: Material is fed into the power roller 2 directly above the feed plate 7. The material filled in the cone hole 21 is squeezed into tablets by the convex cone 31 as the power roller 2 rolls. Under the rotation of the power roller 2 and the auxiliary roller 3, the convex cone 31 disengages from the cone hole 21. The flame retardant tablets are pushed by the spring 24 to the support plate 22, causing the flame retardant tablets to fall off the cone hole 21 and onto the screen plate 8. The screen plate 8 filters out the broken particles and loose materials. The intact flame retardant tablets roll off the screen plate 8 and are collected from the particle collection port 14, while the loose materials and particles are cleaned and collected from the slag removal port 11. In addition, the screen plate 8 is further aided in filtering loose materials and particles by the self-vibration of the vibration mechanism 9.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
