Technical Field

[0001] This utility model relates to the field of fluidized bed granulators, and more specifically, to an improved fluidized bed granulator spray gun device. Background Technology

[0002] The spray gun device of a fluidized bed granulator is an important component of the fluidized bed granulator. It is mainly used to spray liquid materials (such as adhesive solutions) in the form of a mist onto the material particles that are boiling.

[0003] The nozzles used in common granulator spray gun devices are usually in a fixed state, which may result in insufficient droplets being obtained for the material at the edge of the bed. Therefore, an improved fluidized bed granulator spray gun device is needed. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide an improved fluidized bed granulator spray gun device that can drive the nozzle to rotate, avoiding excessive wetting or drying of local materials, thereby making the granulated particles more uniform in size.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] An improved fluidized bed granulator spray gun device includes an inlet pipe, a nozzle rotatably connected to the bottom end of the inlet pipe, a nozzle mounted on the bottom of the nozzle, a rotating rod rotatably connected to the right side of the inlet pipe, an impeller fixedly connected to the left end of the rotating rod, a gear fixedly connected to the right end of the rotating rod, a groove formed on the top of the nozzle, and a toothed groove meshing with the gear on the inner wall of the groove.

[0007] As a further description of the above technical solution:

[0008] The nozzle includes a square tube, the top end of which is fixedly connected to and communicates with the nozzle head. A circular block is rotatably connected to the inner wall of the square tube, and an atomizing hole is opened on the upper part of the circular block. A motor is fixedly connected to the back of the square tube, and the output shaft of the motor passes through the square tube and is fixedly connected to the circular block.

[0009] As a further description of the above technical solution:

[0010] A fixed cylinder is fitted onto the inlet pipe and fixedly connected thereto. The top of the fixed cylinder is open. The inlet pipe has annularly distributed outlets and inlet holes. A sealing plate and a filter plate are fitted onto the inlet pipe and slidably connected thereto. Annularly distributed connecting rods are fixedly connected between the sealing plate and the filter plate. Two electric push rods are fixedly connected to the inlet pipe. The bottom ends of the two electric push rods are fixedly connected to the sealing plate. A solenoid valve is installed on the inlet pipe.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] This design allows the nozzle to rotate, enabling the atomized droplets to cover a larger area of ​​the material bed. In a fluidized bed granulator, the material is in a fluidized state, constantly tumbling and moving. The rotating nozzle ensures that the droplets make more comprehensive contact with the material in the horizontal direction, avoiding spray dead zones. Rotation helps break up the uneven distribution of droplets. Due to the rotation of the nozzle, droplets are sprayed onto the material at different angles and positions, making each material particle have a more equal chance of contacting the droplets. This avoids localized over-wetting or over-drying of the material, resulting in more uniform particle size in the granulation process. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figures 1-5 In this utility model, an improved fluidized bed granulator spray gun device includes an inlet pipe 1, a nozzle 2 rotatably connected to the bottom end of the inlet pipe 1, a nozzle 3 installed at the bottom of the nozzle 2, a rotating rod 4 rotatably connected to the right side of the inlet pipe 1, an impeller 5 fixedly connected to the left end of the rotating rod 4, a gear 6 fixedly connected to the right end of the rotating rod 4, a groove 7 opened at the top of the nozzle 2, and a toothed groove meshing with the gear 6 on the inner wall of the groove 7; the nozzle 3 includes a square tube 301, the top end of the square tube 301 is fixedly connected to and communicates with the nozzle 2, a circular block 302 is rotatably connected to the inner wall of the square tube 301, an atomizing hole 303 is opened on the upper part of the circular block 302, a motor 304 is fixedly connected to the back of the square tube 301, and the output shaft of the motor 304 passes through the square tube 301 and is fixedly connected to the circular block 302.

[0028] In this invention, during use, liquid material enters the nozzle 2 through the inlet pipe 1, then enters the square tube 301, and is atomized and sprayed out through the atomizing holes 303 on the circular block 302. The liquid material is then sprayed in a mist form onto the boiling material particles, achieving the effect of liquid material spraying. During spraying, the liquid material flows in the inlet pipe 1, driving the impeller 5 to rotate. The impeller 5 then drives the rotating rod 4 to rotate, which in turn drives the gear 6. Since the gear 6 meshes with the teeth on the groove 7, the rotation of the impeller 5 drives the nozzle 2 to rotate. After the nozzle 2 rotates, it will drive the circular block 302 to rotate. After the circular block 302 rotates, the atomized droplets can cover the material bed over a larger area. In the fluidized bed granulator, the material is in a fluidized state, constantly turning and moving. The rotating nozzle 2 can ensure that the droplets come into more comprehensive contact with the material in the horizontal direction, avoiding spray dead zones. The rotation helps to break the uneven distribution of droplets. Due to the rotation of the nozzle 2, the droplets are sprayed onto the material at different angles and positions, making each material particle have a more equal chance of contacting the droplets. This can avoid the situation of local material being over-wetted or dry, thereby making the granulated particles more uniform in size.

[0029] During the spraying process, the user can turn on the motor 304 to drive the circular block 302 to rotate, thereby changing the orientation of the atomizing hole 303, achieving the effect of controlling the spraying area, and thus improving the practicality of the device.

[0030] Please see Figures 1-4 The inlet pipe 1 is fitted with a fixed cylinder 8 that is fixedly connected to it. The top of the fixed cylinder 8 is open. The inlet pipe 1 has annularly distributed outlets 9 and inlet holes 10. The inlet pipe 1 is fitted with a sealing plate 11 and a filter plate 12 that are slidably connected to it. Annularly distributed connecting rods 13 are fixedly connected between the sealing plate 11 and the filter plate 12. Two electric push rods 14 are fixedly connected to the inlet pipe 1. The bottom ends of the two electric push rods 14 are fixedly connected to the sealing plate 11. A solenoid valve 15 is installed on the inlet pipe 1. A sealing block 19 is fixedly connected to the inner wall of the inlet pipe 1. The sealing block 19 is located between the outlets 9 and the inlet holes 10.

[0031] In this invention, during the flow of liquid material in the inlet pipe 1, due to the setting of the sealing block 19, the liquid material will flow from the outlet 9 into the sealed space formed by the fixed cylinder 8 and the sealing plate 11. At this time, the liquid material will pass through the filter plate 12, and then the liquid material will re-enter the inlet pipe 1 from the inlet hole 10. Before flowing into the nozzle 2, the liquid material needs to pass through the fixed cylinder 8. When the liquid material passes through the fixed cylinder 8, it will be filtered by the filter plate 12, and the particulate matter in the liquid material will be filtered out, thereby effectively preventing the particulate matter in the liquid material from clogging the atomizing hole 303.

[0032] After a period of use, when a large amount of particulate matter adheres to the surface of the filter plate 12, the user activates the electric push rod 14 to raise the sealing plate 11. After the sealing plate 11 rises, it loses its seal on the fixed cylinder 8. When the filter plate 12 is above the liquid outlet 9, the top of the filter plate 12 will be flush with the top of the fixed cylinder 8. Then, the cleaning fluid is injected into the inlet pipe 1, and then the solenoid valve 15 is closed. At this time, the cleaning fluid in the inlet pipe 1 cannot enter the nozzle 2. The cleaning fluid will accumulate in the fixed cylinder 8, and then the cleaning fluid will reverse and pass through the filter plate 12, thereby achieving the effect of backflushing and cleaning the filter plate 12, and thus achieving the effect of automatic cleaning of the filter plate 12.

[0033] Please see Figure 4 The sealing plate 11 is provided with two sealing rings 16, and the outer sides of the two sealing rings 16 are in contact with the fixed cylinder 8 and the liquid inlet pipe 1, respectively.

[0034] In this invention, the sealing ring 16 can seal the sealing plate 11, the fixed cylinder 8, and the liquid inlet pipe 1.

[0035] Please see Figures 1-3 The bottom of the fixed cylinder 8 is fixedly connected to a protective cylinder 17, which is sleeved on the solenoid valve 15.

[0036] In this invention, when cleaning the filter plate 12, the wastewater is blocked by the protective bucket 17, thereby effectively preventing the wastewater from damaging the solenoid valve 15 and avoiding any impact on the gear 6 and the tooth groove.

[0037] Please see Figure 5 Among them, a shaft seal 18 is installed on the liquid inlet pipe 1, and the inner ring of the shaft seal 18 is fixedly connected to the rotating rod 4.

[0038] In this invention, the shaft seal 18 can effectively prevent leakage between the rotating rod 4 and the liquid inlet pipe 1, thereby improving the practicality of the device.

[0039] The above are merely preferred embodiments of this utility model; however, 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 its improved concept, should be included within the scope of protection of this utility model.
