Description

Technical Field

[0001] This utility model relates to the field of fireworks sparkling bead processing technology, and in particular to a disc granulator. Background Technology

[0002] Flame beads are particulate materials formed by granulation of oxidizing agents, reducing agents, and metals or metal oxides that have a flame test effect. They generally consist of two parts: an inner core that produces the corresponding effect and an outer coating that mainly serves as an ignition agent. Currently, the production of flame beads involves four processes: granulation of the inner core, drying of the inner core granules, coating the inner core granules with the outer coating agent, and drying to obtain the finished product.

[0003] The third step in the manufacturing process—encapsulating the inner core particles with the outer coating—is extremely important. The outer coating is a slow-burning layer, and its combustion speed is regulated through a zero-oxygen balance design. Potassium nitrate, potassium perchlorate, and phenolic resin are commonly used, accounting for 10%-40% of the total weight of the bright beads. This ensures that the bright beads fully develop color after being sprayed out, rather than burning prematurely inside the tube.

[0004] Existing methods primarily involve placing the inner core and outer coating agent into a rotating pot for coating. For example, patent number 201520778317.8, titled "Fireworks Bead Coating Machine," specifically includes a main frame and a coating pot. The coating pot is mounted on the main frame via a rotating bracket. Below the coating pot are a pill hopper and a discharge mechanism. The main frame also includes a first drive mechanism for driving the coating pot to rotate around its axis to roll the pills, and a second drive mechanism for driving the coating pot to rotate around the axis of the rotating bracket to unload the formed pills through the pill hopper to the discharge mechanism. This invention uses the first drive mechanism to drive the coating pot to rotate around its own axis to roll the pills, and the second drive mechanism to drive the coating pot to rotate around the axis of the rotating bracket by a certain angle, thereby automatically unloading the formed pills through the pill hopper to the discharge mechanism. This achieves automated control in the production of fireworks beads, improving both processing efficiency and safety.

[0005] However, in the existing technology, the rotating external medicine wrapping can cause safety accidents due to frictional heat generation. Therefore, the amount processed at one time cannot be too large, which reduces production efficiency. In addition, manual loading and unloading are required, which is not easy to operate.

[0006] In view of this, the present invention proposes a disc granulator.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A disc granulator includes a frame and a granulation disc disposed within the frame.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0041] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] like Figures 1 to 3 As shown, the main supporting component of the technical solution in this embodiment is the frame 1, the main functional component is the granulation disc 2, and it also includes the following parts: 1. Environmentally friendly particle storage component 3; 2. Powder storage component 4; 3. Spraying component 5; 4. Rotation component 6; 5. Unloading component; 6. Control cabinet 10.

[0044] Both the environmentally friendly particle storage component 3 and the powder storage component 4 are fixedly installed on the upper section of the frame 1, and their outlets are located inside the granulation disc 2. They are used to convey the inner core granules and the outer coating granules to the granulation disc 2. Their specific structures are as follows:

[0045] As attached Figure 1 With appendix Figure 4 As shown, the structure of the environmentally friendly particle storage component 3 includes an I-beam steel set above the frame 1, and square steel welded to the outer periphery of the environmentally friendly particle storage hopper 31. The square steel is connected to the frame 1 and fixed by welding, so that the particle storage hopper can pass through the top of the frame 1. A particle conveying pneumatic valve 32 is set at the outlet of the particle storage hopper, and a particle conveying pipe 33 is set at the other end of the particle conveying pneumatic valve 32. The particle conveying pipe 33 should be a deformable and fixed rigid hose, so that the position of the outlet can be adjusted at will. No matter how it is adjusted, the outlet of the particle conveying pipe 33 should be located inside the granulation disc 2.

[0046] As attached Figure 1 With appendix Figure 5As shown, the powder storage component 4 is similarly configured, and is fixedly connected to the frame 1 by a square steel, so that the powder feeding hopper 41 can pass through the frame 1. A vibrating feeder 42 is set below the powder feeding hopper 41. It can be seen that the powder is fed by vibration. The main reason for not using a valve is that it is difficult to control the amount of powder conveyed and it is not easy to close. An activation hopper 43 is set below the vibrating feeder to ensure that the powder does not stick in the hopper. At the same time, a powder conveying pipe 44 is set below the activation hopper 43. The requirements of the powder conveying pipe 44 are the same as those of the particle conveying pipe 33, which facilitates the adjustment of the outlet position and ensures that the position of the powder conveying pipe 44 is located inside the granulation disc 2.

[0047] The presence of both the environmentally friendly particle storage component 3 and the powder storage component 4 ensures the continuity of the feeding process with minimal manual intervention. In order to measure the amount of powder and particles being conveyed at any time, a metering device 9 is installed on the outside of both the powder feeding hopper 41 and the environmentally friendly particle storage hopper 31 to detect the amount of powder and particles being conveyed, so as to facilitate the adjustment of the amount of powder and particles and ensure the processing quality.

[0048] As attached Figure 2 With appendix Figure 3 As shown, in order to ensure that the granulation disc 2 can rotate, a rotating assembly 6 is provided at the bottom of the granulation disc 2. The specific structure is as follows: a rotary motor 61 is provided at the bottom of the granulation disc 2, thereby ensuring that the granulation disc 2 can rotate. Secondly, in order to adjust the tilt angle during the production process and facilitate subsequent unloading, a rotating shaft 62 is provided on one side of the rotary motor 61. Multiple bearing seats 65 are provided in the middle of the rotating shaft 62. The bearing seats 65 are fixedly provided on the frame 1. The bearing seats 65 are mainly to ensure stability during rotation. A reduction gearbox 63 and a drive motor 64 are provided at the other end of the rotating shaft 62. The rotation of the rotating shaft 62 is achieved by the forward and reverse rotation of the drive motor 64 and through the reduction gearbox 63, thereby adjusting the rotation of the granulation disc 2.

[0049] As attached Figure 1 Appendix Figure 2 With appendix Figure 3 As shown, since the spray assembly 5 needs to transport binder or clean water (a few spray heads 53 can be connected to an external water circuit) inside the granulation disc 2, it needs to rotate together with the granulation disc 2 during rotation. Therefore, the spray assembly 5 includes a spray bracket 52 set on the rotating shaft 62. The spray bracket 52 is U-shaped, with one end located above the granulation disc 2. At the same time, the other end of the spray bracket 52 is a rectangular support bar. Several spray heads 53 are installed at equal intervals on the support bar. A binder storage box 51 is set below the frame 1. A plunger metering pump (not shown in the figure, but it is conventional technology) is set in the binder storage box 51. The plunger metering pump is connected to several spray heads 53 through the main pipeline and the branch pipe.

[0050] As attached Figure 1 As shown, a hopper 7 is provided on the frame 1 below the granulation disc 2 to collect and discharge the processed particles. Therefore, a guide plate 8 is also provided on the frame 1 below the hopper 7 to discharge the collected particles. Although not shown in the attached figure, a particle conveyor is provided below the guide plate 8 to transport the particles out. The particle conveyor can be a rotating item such as a transfer box, transfer bucket, or belt conveyor.

[0051] As attached Figure 1 As shown, there is also an air tank on the frame 1, which is used to supply high-pressure air to components that require high-pressure air throughout the process, such as the pressurization device added to the spray head 53 and the particle conveying pneumatic valve 32.

[0052] There is also a control cabinet 10, which is used to receive corresponding signals, such as the meter 9. It also has a corresponding timing function, mainly controlling the rotation time of the rotary motor 61. It also contains electronic components such as the rotary motor 61, drive motor 64, plunger metering pump, particle conveying pneumatic valve 32, and vibrating feeder. Through the control of the control cabinet 10, the separation of personnel and materials is achieved, reducing safety hazards and increasing the degree of automation.

[0053] The control cabinet 10 is equipped with a metering system. Two meters 9 detect the amount of environmentally friendly particles and powder being added in real time and transmit the data to the control cabinet 10. At the same time, the plunger metering pump detects and transmits the amount of binder added to the control cabinet 10 in real time. The metering system of the control cabinet 10 feeds back the received amounts of environmentally friendly particles, powder and binder to the particle conveying pneumatic valve 32, vibrating feeder 42 and plunger metering pump to adjust the input values ​​of the corresponding materials. This ensures that the mixing ratio of the three is the same and guarantees the consistency of the final product.

[0054] The working process of this utility model:

[0055] 1. Manually add the corresponding environmentally friendly particles and powders to the environmentally friendly particle storage hopper 31 and the powder feeding hopper 41.

[0056] 2. Control the rotary motor 61 of the control cabinet 10 to rotate the granulation disc 2 clockwise to open (the granulation disc 2 is tilted during the processing), and control the pneumatic valve 32 for particle conveying below the environmentally friendly particle storage hopper 31 to open, so as to put a certain amount of environmentally friendly particles into the granulation disc 2.

[0057] 3. Control cabinet 10 controls the plunger metering pump to start, spraying the environmentally friendly particles in the granulation disc 2 with binder (to reduce the heat generated by friction and increase the adhesion to the powder). After the amount of binder and environmentally friendly particles reaches the predetermined ratio, the powder is fed in.

[0058] 4. Control cabinet 10 controls the vibrating feeder 42 to control the amount of powder and binder to be evenly distributed within a certain ratio range, and continuously feeds powder and sprays binder.

[0059] 5. After the material has been continuously rotating in the pan for a certain period of time, it begins to discharge particles. The particles fall into the collecting hopper 7 and are then conveyed into the guide plate 8 and transported to the outside.

[0060] 6. After the overall work is completed, high-pressure air from the air tank is added to the spray head 53, which is connected to the external water source, and high-pressure water is delivered to complete the automatic rinsing of the granulation disc 2.

[0061] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
