Description

Technical Field

[0001] The invention relates to the technical field of fireworks production equipment, and in particular to a fireworks bright bead granulation method and a disc granulator. Background Art

[0002] As the core component of fireworks products, the quality of fireworks beads directly affects the effect of fireworks. Traditionally, disc granulators are used to produce bright beads. The disc granulator rotates to make the materials inside the disc roll and collide, gradually forming particles.

[0003] The roundness of bright beads is one of the key indicators. Insufficient roundness will lead to unstable trajectory and unsatisfactory effect during firing. Therefore, the bright beads need to be polished after granulation to improve the roundness. When the disc bright beads are granulated, high-speed rotation (normal speed is 15-25rpm) is required to achieve rapid granulation of the material. When polishing the bright beads, the speed of the disc needs to be reduced (normal speed is 5-10rpm). The particles inside the disc are mainly "rolling" to reduce falling and violent collisions, so as to achieve round particles. Therefore, a disc granulator can only perform granulation or polishing work alone. The granulation and polishing of the bright beads cannot be carried out at the same time, and the production efficiency is low; if granulation and polishing are carried out at the same time, two disc granulation equipment need to be configured, which increases the investment cost of the production equipment.

The auxiliary material feeding device is a spiral feeding device, and the discharge port of the spiral feeding device extends to the top of the first disc 2, which is used to feed auxiliary particles into the first disc 2. The auxiliary material feeding device is generally used for feeding small particles such as cement core.

[0029] The first disc 2 is filled with raw material powder of bright beads particles, which is a raw material mixture for forming bright beads in the prior art. After entering the first disc 2, the raw material powder of the bright beads particles contacts with water mist to form a wet material. The first disc 2 is tilted and rotated, and the wet material can be wrapped on the surface of the auxiliary particles. The auxiliary particles roll under the action of centrifugal force and gravity, and the wet material on the surface of the auxiliary particles is wrapped and thickened layer by layer. When the particles reach the target size, formed particles 26 are obtained. Due to the action of gravity and centrifugal force, the formed particles 26 will gradually move to the edge of the first disc 2 and be automatically discharged from the edge of the first disc 2.

[0030] The first motor 10 drives the first shaft 11 to rotate, so that the first disc 2 is tilted, and the second motor 13 drives the first disc 2 to rotate, so as to realize the tilting and rotating action of the first disc 2. The tilt angle and rotation speed of the first disc 2 can be adjusted according to production requirements, and different tilt angles and rotation speeds of the first disc 2 can produce bright beads of different particle sizes.

Reference Fig.11 When the second disc 3 is stationary, the feed port of the feed channel 34 is located at the top of the material channel, and the feed port of the feed channel 34 is blocked by the second baffle ring 6. The push plate 43 pushes the formed particles 26 to the top of the second disc 3 (which is also the top of the material channel), and the formed particles 26 can enter the second disc 3 from the feed channel 34.

[0048] The working process of this disc granulator is: Step 1: The first motor 10 rotates and positions the first shaft 11, so that the first disc 2 has a target tilt angle, the second motor 13 drives the second shaft 12 to rotate, and the first disc 2 rotates along with the second shaft 12, so that the first disc 2 is kept at the target speed and is in a tilted rotation state; At this time, the first combining plate 16 is separated from the combining surface 36, the second combining plate 23 is separated from the third combining plate 222, the second disc 3 and the movable sleeve 41 do not rotate, the feeding channel 34 is located at the top of the second disc 3, the discharging channel 35 is located at the bottom of the second disc 3, and the pushing plate 43 is located at the initial position; Step 2: The spraying part 28 sprays water mist, and the auxiliary particles and the raw material powder of the bright bead particles enter the first disc 2. The raw material powder of the bright bead particles contacts with the water mist to form a wet material. The first disc 2 tilts and rotates, and the auxiliary particles roll under the action of centrifugal force and gravity. The wet material gradually thickens on the surface of the auxiliary particles to obtain formed particles 26. The formed particles 26 can be automatically discharged from the opening edge of the first disc 2 and enter the interior of the storage cylinder 4 through the material channel. Step 3: When the formed particles 26 in the storage cylinder 4 accumulate to a certain amount, the third functional cylinder 44 drives the contact plate 441 to move, so that the contact plate 441 pushes the feed baffle 31, and the feed baffle 31 leaves the feed channel 34, and the feed channel 34 is in an open state; Step 4: The second functional cylinder 24 drives the second combining plate 23 to move axially, so that the second combining plate 23 is combined with the third combining plate 222, and the fourth shaft body 221 can rotate with the third shaft body 21 to realize the rotation of the third wheel body 22. The third wheel body 22 rotates with the gear ring 9, the movable sleeve 41 rotates, and the push plate 43 rotates with the movable sleeve 41. Fig.11 The push plate 43 pushes the formed particles 26 at the bottom of the storage tube 4 to the top of the storage tube 4, and the formed particles 26 enter the interior of the second disc 3 when passing through the feed channel 34; At this time, the first disc 2 continues to perform granulation work to form new formed particles 26, and the new formed particles 26 can continue to enter the bottom of the storage cylinder 4; Step 5: Reference Fig.12 When the push plate 43 contacts the edge of the feed channel 34, it can be considered that all the formed particles 26 on the top of the storage cylinder 4 have entered the second disc 3. At this time, the third functional cylinder 44 drives the contact plate 441 to return, and the feed baffle 31 returns under the action of the elastic member 324. The feed baffle 31 closes the feed channel 34, and the feed channel 34 is in a closed state; Step 6: The push plate 43 and the movable sleeve 41 continue to rotate, the push plate 43 returns to the initial position, the second functional cylinder 24 drives the second combining plate 23 to move axially, so that the second combining plate 23 is separated from the third combining plate 222, and the movable sleeve 41 and the push plate 43 do not rotate; At the same time, the first functional cylinder 17 drives the first combining plate 16 to move axially, so that the first combining plate 16 is combined with the combining surface 36, and the second disc 3 rotates synchronously with the first disc 2. At the same rotation speed, the formed particles 26 are subjected to less force inside the second disc 3 with a smaller diameter, and roll more gently, so that the polishing work of the formed particles 26 can be achieved, which helps to improve the roundness of the formed particles 26. Step 7: After the molded particles 26 are polished inside the second disc 3, the first functional cylinder 17 drives the first combining plate 16 to move axially, so that the first combining plate 16 is separated from the combining surface 36, the second disc 3 stops rotating, the feed channel 34 is located at the top of the second disc 3, the discharge channel 35 is located at the bottom of the second disc 3, the discharge channel 35 is opened, and the molded particles 26 leave the second disc 3 from the discharge channel 35; Repeating steps 3 to 7 can achieve continuous granulation of bright beads and continuous polishing of formed particles 26.

[0049] The disc granulator utilizes the granulation rotational power to realize the polishing work of the bright bead formed particles, which saves power, and the granulation work and polishing work can be carried out at the same time, realizing the continuous granulation work and polishing work of the bright beads, and the processing efficiency is high.

[0050] The present invention also provides a method for granulating fireworks beads, which is implemented by the above-mentioned disc granulator. Figure 1 The method for making fireworks bright beads comprises the following steps: A1: Put the raw material powder of fireworks bright beads and auxiliary particles into the first disc 2 of the disc granulator, and spray water mist into the first disc 2. The first disc 2 is used to rotate in a tilted state to realize the granulation of the raw material powder.

[0051] Among them, the raw material powder of fireworks bright beads particles is fed through supporting raw material feeding equipment, such as an activation hopper. The activation hopper activates the material through vibration, which can effectively eliminate the arching, clogging and sticking of the material, and avoid the problem of poor feeding of the raw material powder of fireworks bright beads particles. Auxiliary particles can also be fed through supporting auxiliary material feeding equipment, such as spiral feeding equipment, to maintain continuous feeding of auxiliary particles. A water spray part can be provided above the first disc 2 of the disc granulator, and the spray part is used to spray water mist into the inside of the first disc 2 to assist in the granulation of the raw material powder of fireworks bright beads particles.

[0052] The auxiliary particles are core particles, and the particle size of the auxiliary particles is smaller than the target particle size of the fireworks bright beads. The core particles are particles or substances that serve as the core in the granulation process. These core particles can be pre-prepared small particles, such as cement cores, or they can be cores naturally formed during the granulation process, such as small particle bright beads. During the granulation process, the core particles are wrapped and thickened layer by layer by the powder material on the disc granulator to finally form the desired particle size and shape, that is, to form bright bead particles of the target particle size. The diameter of the auxiliary particles in this embodiment is generally 1-2 mm.

[0053] The control factors of the target particle size of the fireworks bright beads include but are not limited to the inclination angle of the first disc 2, the rotation speed of the disc and the water-powder ratio. The inclination angle of the first disc 2 refers to the angle between the first disc 2 and the horizontal plane, the rotation speed of the disc refers to the rotation speed of the disc during granulation, and the water-powder ratio refers to the mass ratio of the water sprayed into the first disc 2 to the mass ratio of the raw material powder of the fireworks bright beads particles. By controlling the inclination angle of the first disc 2, the rotation speed of the disc and the water-powder ratio, the target particle size of the bright beads particles can be controlled.

[0054] A2: After reaching the target particle size, the fireworks beads overflow from the first disc 2 and leave the first disc 2. The formed beads particles continuously leave the first disc 2, and the raw material powder of the fireworks beads particles continuously enters the first disc 2, realizing the continuous processing of the beads particles.

[0055] A3: The overflowed fireworks beads are polished inside the second disc 3. The polishing process can improve the roundness of the fireworks beads.

[0056] The fireworks bright bead granulation method in this embodiment realizes the granulation of fireworks bright bead by a disc granulator, and obtains bright bead particles that meet the target particle size and have uniform particles by adjusting the inclination angle, rotation speed, and water-powder ratio of the first disc 2. The manufacturing process is simple; after the bright bead particles reach the target particle size, they can automatically overflow from the first disc 2, and the raw material powder of the fireworks bright bead particles is continuously fed to maintain continuous granulation of the granulation work, which is suitable for large-scale and efficient production. In addition, the fireworks bright bead granulation method incorporates core particles into the first disc 2. During the granulation process, the raw material powder of the fireworks bright bead particles can be wrapped on the surface of the core particles to form particles, thereby improving the formation efficiency of the bright bead particles.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
