Description

Technical Field

[0001] The utility model belongs to the technical field of spray gun structures and relates to a spray gun structure of boiling drying granulation equipment. Background Art

[0002] A boiling granulator is a machine primarily used for pharmaceutical granulation and coating, characterized by safe operation and a high degree of automation. Existing boiling drying granulators utilize a hot air flow under negative pressure to suspend the powder into a fluidized state. A binder (which can be a concentrated solution) is then sprayed onto the powder using an airflow nozzle, causing it to condense into porous particles. However, the internal spray gun, when spraying the product, simply rotates the product through internal air pressure. This effect is greatly reduced if the spray gun is stationary, resulting in uneven spraying. Furthermore, the spray guns are currently all located in the same position, spraying internally, which greatly reduces spraying efficiency and impacts production progress. Therefore, to address the above issues, a spray gun structure for boiling drying granulation equipment is proposed. Utility Model Content

At the same time, the internal structures of the four components are the same. A driving disk 7, an adjusting disk 8, a supporting block 11, a supporting rod 12 and a nozzle assembly 15 are provided in the first spray gun assembly 3, and an adjusting disk 8 is provided on the side of the driving disk 7. At the same time, a positioning pin 9 is provided between the driving disk 7 and a corner of the adjusting disk 8, a pin nail 10 is provided on the side of the driving disk 7, and the outer end of the pin nail 10 is inserted in the other side of the adjusting disk 8, one end of a rotating column 16 is inserted on the back of the driving disk 7, and a motor 17 is provided on the other side of the rotating column 16. At the same time, the motor 17 is placed in the middle of the wall of the support frame 2, a connecting block 14 is provided above the adjusting disk 8, and one end of a support rod 12 is provided on the back of the connecting block 14, and a nozzle assembly 15 is provided on the front of the connecting block 14, the other end of the support rod 12 is inserted in the support block 11, and a spiral spring 13 is provided on the other side of the support rod 12.

[0026] The support frame 2 is provided with four legs, and the four legs are equidistantly placed outside the main cylinder 1. A built-in space 201 is opened in the middle of the legs of the support frame 2, and the four built-in spaces 201 are successively increased in height. The bottom of the motor 17 is fixedly connected in the built-in space 201, and the middle of the rotating column 16 is inserted into the side of the built-in space 201 for rotation connection. At the same time, the inserted end of the rotating column 16 is fixedly connected to the shaft end of the motor 17.

[0027] Furthermore, the other end of the rotating column 16 is inserted into the wall of the rotating connection main cylinder 1, and the inserted end of the rotating column 16 is fixedly connected to the middle of the side of the driving disk 7. At the same time, there is a distance between the driving disk 7 and the inner wall of the main cylinder 1. The other side of the driving disk 7 is inserted into and fixedly connected to one end of multiple positioning pins 9, and multiple positioning pins 9 divide the side of the driving disk 7 equally. At the same time, the other end of the positioning pin 9 is inserted into a corner of the rotating connection adjustment disk 8.

[0028] After a motor 17 is installed in the middle of the leg of the support frame 2, the motor 17 is connected to one end of the rotating column 16, and the other end of the rotating column 16 is inserted into the main cylinder 1 to connect the drive disk 7. In this way, after the motor 17 is started, it can drive the drive disk 7 to rotate, and multiple adjustment disks 8 are provided on one side of the drive disk 7, so the adjustment disk 8 also rotates together.

[0029] One end of a plurality of pins 10 is inserted through the other side surface of the driving disk 7 and connected by threads, and the plurality of pins 10 equally divide the side surface of the driving disk 7 , and the pins 10 correspond to the positioning pins 9 .

[0030] Furthermore, an adjustment slide portion 801 is opened on one side of the adjustment disk 8 , and the adjustment slide portion 801 corresponds to the positioning pin 9 , and the middle of the sliding connection pin 10 is inserted into the adjustment slide portion 801 .

[0031] The pin 10 provided on the driving disk 7 is inserted into the adjusting slide portion 801 at the upper end of the adjusting disk 8. Since the adjusting slide portion 801 has a certain length, after moving the adjusting disk 8, the pin 10 is tightened so that the nail head of the pin 10 is pressed on the adjusting disk 8. In this way, the side of each adjusting disk 8 protrudes from the driving disk 7 by different distances.

[0032] One side of the support block 11 is fixedly connected to the inner wall of the main barrel 1 , and the other side of the support block 11 is inserted into one end of a rotatably connected support rod 12 .

[0033] Furthermore, the spiral spring 13 is inserted into the other side of the support block 11 . Remember that the spiral spring 13 is wound around one end of the support rod 12 .

[0034] The spiral spring 13 provided in the support block 11 is also wound around one end of the support rod 12 , so that in the absence of external force, the support rod 12 is fixed in a certain position by the spiral spring 13 .

[0035] Furthermore, the other side of the support rod 12 is inserted into the fixed connection block 14 , and the front side of the connection block 14 is fixedly connected to the nozzle assembly 15 .

[0036] Furthermore, a track is provided on the side of the connecting block 14 , and the track is inserted into the upper side of the sliding connection adjustment plate 8 .

[0037] After the driving disk 7 rotates, the adjusting disk 8 will continue to press against the connecting block 14. Since the protruding distance of each adjusting disk 8 is different, the swinging position of the connecting block 14 is changed. In this way, the nozzle assembly 15 in front of the connecting block 14 is always spraying in a swinging manner when working.

[0038] The first spray gun assembly 3 is symmetrical with the third spray gun assembly 5 , and the second spray gun assembly 4 is symmetrical with the fourth spray gun assembly 6 . The first spray gun assembly 3 , the third spray gun assembly 5 , the second spray gun assembly 4 , and the fourth spray gun assembly 6 are in a cross shape when viewed from above.

[0039] The first spray gun assembly 3 , the second spray gun assembly 4 , the third spray gun assembly 5 and the fourth spray gun assembly 6 provided in the main barrel 1 correspond to different positions inside the main barrel 1 for spraying.

[0040] Working principle:

[0041] The main barrel 1 and the support frame 2 are respectively provided with a first spray gun assembly 3, a second spray gun assembly 4, a third spray gun assembly 5 and a fourth spray gun assembly 6 which are successively increased in height, and the four assemblies have the same structure, so that the spraying in the main barrel 1 will be different, so that the internal spraying will be uniform, and a driving disk 7 is provided in the spray gun assembly. It is driven by the motor 17 and the rotating column 16 to rotate, and a plurality of adjustment disks 8 are provided on the side of the driving disk 7. At the same time, a positioning pin 9 is provided between the driving disk 7 and one corner of the adjustment disk 8, so that the adjustment disk 8 can rotate with the positioning pin 9 as the base point, and the driving disk 7 and the adjustment disk 8 on the other side are rotated. There is a pin nail 10 in the middle. After moving the adjustment disk 8, use the pin nail 10 to tighten and press it, so that the distance between the side of each adjustment disk 8 and the driving disk 7 is not equal. The protruding side of the adjustment disk 8 is inserted into the track on the side of the connecting block 14, and the back of the connecting block 14 is inserted into one end of the support rod 12. At the same time, after the other end of the support rod 12 is inserted into the support block 11, a spiral spring 13 is provided inside. When the drive disk 7 rotates, the adjustment disk 8 continuously lifts the connecting block 14, and the lifting distance is different, so that the sprinkler assembly 15 on the front of the connecting block 14 swings and sprays.
