[0002] A mixing granulator is a widely used piece of equipment in the pharmaceutical, chemical, and food industries. It is used to mix powdered materials and form granules by adding water or other liquid components. It can improve the uniformity of materials, enhance flowability and compressibility, and is suitable for producing granulated pharmaceuticals, fertilizers, and feed. In existing mixing granulators, workers typically add multiple chemical raw materials sequentially into the mixing device. This can cause some of the initially added raw materials to accumulate at the bottom of the device, resulting in poor mixing and affecting production requirements. Therefore, we propose a mixing granulator with raw material pretreatment. Utility Model Content

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figure 1-4 As shown, this utility model proposes a mixing and granulating machine with raw material pretreatment, including a mixing chamber 1. Two sets of storage hoppers 2 are arranged above the mixing chamber 1. Each set of storage hoppers 2 is equipped with a baffle 14, which is fixedly connected to the inner wall of the storage hopper 2. The baffle 14 divides the storage hopper 2 into two parts. The arrangement of the baffle 14 and the storage hopper 2 allows the operator to feed different raw materials into the storage hoppers 2 respectively. An mounting plate 3 is arranged between the storage hoppers 2 and the mixing chamber 1. One side of the mounting plate 3 is fixedly connected to the mixing chamber 1, and a discharge port is opened on the mounting plate 3. The lower part of the two sets of storage hoppers 2 is installed corresponding to the discharge port. The other side of the mounting plate 3 is fixedly connected to the mounting end of the two sets of storage hoppers 2. A feeding mechanism 4 is arranged below the mounting plate 3. The feeding mechanism 4 includes multiple sets of electric push rods 41 arranged on both sides of the mixing chamber 1. The output end of each set of electric push rods 41 is connected to a baffle 42, and each set of baffles 42 corresponds to a storage hopper. The material hole below the storage hopper 2 is blocked by the baffle 42, which allows the raw materials in the storage hopper 2 to be discharged simultaneously or separately. Multiple sets of fixing strips 43 are provided on one side of the mounting plate 3, with the mounting ends of the fixing strips 43 fixedly connected to one side of the mounting plate 3. The mounting end of the electric push rod 41 is fixedly connected to one side of two sets of mutually distant fixing strips 43. Multiple sets of guide rods 44 are provided between each set of fixing strips 43, with both ends of the guide rods 44 fixedly connected to the fixing strips 43. The mounting end of each set of baffle 42 is correspondingly installed with the two sets of guide rods 44, and the mounting end of baffle 42 is slidably connected to the guide rods 44. The guide rods 44 limit and guide the baffle 42. The feeding mechanism 4 blocks the material hole below the storage hopper 2, preventing the raw materials from automatically sliding into the pelletizer 11 below when fed into the storage hopper 2, thus preventing insufficient mixing of the raw materials.

[0021] A raw material guide hopper 5 is installed below the mounting plate 3 inside the mixing box 1. The mounting end of the raw material guide hopper 5 is installed corresponding to the inner wall of the mixing box 1 and is fixedly connected to the inner wall of the mixing box 1. The raw material guide hopper 5 is located directly below the discharge port. The raw material guide hopper 5 is designed to guide the raw materials falling from the storage hopper 2. Below the raw material guide hopper 5, a mixing bin 6 is installed inside the mixing box 1. The mounting end of the mixing bin 6 is installed corresponding to the inner wall of the mixing box 1 and is fixedly connected to the inner wall of the mixing box 1. The mixing chamber 6 is arc-shaped and can catch raw materials falling from the raw material guide hopper 5. A motor 7 is installed on one side of the mixing box 1, with its mounting end corresponding to one side of the mixing box 1 and fixedly connected. The output end of the motor 7 is located inside the mixing box 1 and connected to a rotating rod 8, which is fixedly connected to one end of the rotating rod 8. A shaft hole is provided on one side of the mixing box 1, and one end of the rotating rod 8 is installed corresponding to this shaft hole, rotatably connected to it. The outer ring of the mixing chamber 6 is provided with stirring blades 9. The mounting end of the stirring blades 9 is installed correspondingly to the outer circumference of the rotating rod 8, and the mounting end of the stirring blades 9 is fixedly connected to the rotating rod 8. The outer ring of the stirring blades 9 is in close contact with the inner wall of the mixing chamber 6. The arrangement of the rotating rod 8 and the stirring blades 9 can agitate the raw materials collected in the mixing chamber 6, thereby making the raw materials more uniformly mixed. A feeding hopper 10 is provided below the mixing chamber 6. The mounting end of the feeding hopper 10 is installed correspondingly to the bottom of the mixing chamber 1, and the mounting end of the feeding hopper 10 is fixedly connected to the bottom of the mixing chamber 1. The bottom of the mixing chamber 6 A feeding trough 15 is provided, and the receiving port of the feeding hopper 10 is installed correspondingly to the feeding trough 15. A pelletizer 11 is provided below the feeding hopper 10. The pelletizer 11 is a mature existing technology product, and its internal structure will not be described in detail in this application. The side of the feeding hopper 10 away from the mixing box 1 is installed correspondingly to the top of the pelletizer 11, and the other side of the feeding hopper 10 is fixedly connected to the mixing box 1. The setting of the feeding hopper 10 can guide the mixed raw materials on the mixing bin 6 to fall into the pelletizer 11 through the feeding trough 15, thereby enabling better pelletizing operations.

[0022] A fixing frame 12 is provided around the outer ring of the mixing box 1. The mounting end of the fixing frame 12 is installed corresponding to the outer wall of the mixing box 1, and the fixing frame 12 is fixedly connected to the mixing box 1. Multiple sets of fixing support rods 13 are provided on both the upper and lower sides of the fixing frame 12. One end of the multiple sets of fixing support rods 13 on the upper side of the fixing frame 12 is installed corresponding to the outer side of the storage hopper 2, and the two ends of the multiple sets of fixing support rods 13 on the upper side of the fixing frame 12 are fixedly connected to the fixing frame 12 and the storage hopper 2, respectively. One end of the multiple sets of fixing support rods 13 on the lower side of the fixing frame 12 is installed corresponding to the outer side of the pelletizer 11, and the two ends of the multiple sets of fixing support rods 13 on the lower side of the fixing frame 12 are fixedly connected to the fixing frame 12 and the pelletizer 11, respectively. The fixed connection of device 11, the setting of fixed rib frame 12 and fixed support rod 13 can make the whole device more stable, so that the granulation operation can be carried out more orderly. The overall structure of the device is simple. The storage hopper 2, together with the multiple sets of feeding mechanisms 4 on one side of the mounting plate 3, can store a variety of different raw materials in the storage hopper 2. At the same time, the electric push rod 41 and the baffle 42 can block and discharge the bottom of the storage hopper 2. Meanwhile, the mixing bin 6, motor 7, rotating rod 8 and stirring blade 9 can turn and mix the raw materials falling in the storage hopper 2, so that the raw materials are mixed more evenly and avoid the initial raw materials from piling up at the bottom, thus making the granulation operation more in line with production requirements.

[0023] In this embodiment, the operator first puts the raw materials to be granulated into different storage hoppers 2 in sequence. Then, the operator turns on the electric push rod 41, which drives the baffle 42 to slide along the guide rod 44, so that the baffle 42 no longer blocks the material hole below the storage hopper 2. The raw materials in the storage hopper 2 are discharged at the same time. When a certain amount of raw materials have fallen, the operator turns on the electric push rod 41 to drive the baffle 42 back to its initial state, and re-blocks the bottom of the storage hopper 2. The raw materials falling from the storage hopper 2 are guided by the raw material guide hopper 5 and fall onto the mixing bin 6. Then, the operator turns on the motor 7 and starts it. The motor 7 drives the stirring blade 9 to rotate through the rotating rod 8. The rotating stirring blade 9 turns and mixes the raw materials falling onto the mixing bin 6. After being turned, the raw materials in the mixing bin 6 fall naturally through the discharge chute 15 and are guided by the discharge hopper 10 into the granulator 11, thus completing the granulation operation.
