Description

Technical Field

[0001] This utility model relates to the field of food, chemical and pharmaceutical equipment technology, and specifically to a rotary diffuser. Background Technology

[0002] Water chestnut sugar coating machines are mainly used in the pharmaceutical industry for the production of sugar coatings for pills and tablets. They can also be used in the food, light industry, and chemical industries for rolling, mixing, polishing, and dusting spherical or granular materials to make the materials gradually expand during rotation.

[0003] For example, Chinese utility model patent application number 202222912213.4 discloses a water chestnut-type coating machine, belonging to the field of coating mixing technology, which solves the problems of the inability to adjust the angle of the coating pan and the large space occupation of the structure design in traditional coating machines. It mainly includes a coating pan, a drive mechanism, and a coating pan angle adjustment mechanism. The coating pan angle adjustment mechanism includes an end arm, a forearm connecting rod, and a lead screw sleeve. The lead screw, which is adapted to the lead screw sleeve, is connected to a bearing seat fixed on the machine frame via a bearing. The drive shaft, which is connected to the reducer, passes through the fulcrum fixing platform and is connected to the fulcrum fixing platform bearing. The fulcrum fixing platform is supported by a support fixed on the frame and can rotate relative to the support. The coating pans (water chestnut pans) of this type of water chestnut-type coating machine are all open, and powder is manually sprinkled into the water chestnut pan. This method of sprinkling powder makes it easy for the powder to fly out, resulting in uneven powder distribution, wasting powder, polluting the processing environment, and causing high labor intensity.

The lower end of the support 6 is provided with multiple universal wheels 51 with brakes.

[0029] The working principle of this utility model is as follows:

[0030] 1. Start the screw jack 38 to drive the support 39, the third motor 40, the transmission shaft 41, the hollow ball 42 and the water chestnut pot 4 to swing up and down, adjust the water chestnut pot 4 to a suitable angle, open the small front door 56 and put the material into the water chestnut pot 4, and adjust the position of the spray gun 63 by using the steering locking block 60, bolt 61 and crossbar 62;

[0031] 2. Adjust the up and down position of the movable air pipe 68 by rotating the rotating plate 72 and the long screw 71 and insert it into the water chestnut pot 4. Close the small front door 56 and rotate the handle 58 to limit the small front door 56. Then move the bracket 6 through the universal wheel 51 to insert the feed pipe 5 into the third through hole 22 and the water chestnut pot 4, and lock the brake.

[0032] 3. Open the butterfly valve 35 to blow air into the water chestnut pot 4 through the air inlet pipe 33, and exhaust the air in the enclosed space to the outside to carry out dust removal. Start the third motor 40 to drive the water chestnut pot 4 to rotate forward.

[0033] 4. Start the second motor 23 to drive the stirring shaft 24, stirring frame 25 and spiral conveyor 26 to rotate, stir the powder in the hopper 10 and convey it into the three-way pipe 8. At the same time, start the first motor 7 to drive the synchronous pulley 13 and synchronous belt 14 to move. The synchronous pulley 13 drives the spiral conveyor shaft 11 to rotate and convey the powder in the three-way pipe 8 to the right.

[0034] 5. Rotary joint 20 connects to an external air source for ventilation. When the powder is conveyed to the end of the conveying pipe 5, the airflow blows the powder in the conveying pipe through multiple rows of through holes. When blowing downwards, the powder is blown out from the transverse discharge through hole 18, achieving the effect of spreading powder and making the powder more evenly spread on the material in the water chestnut pot 4.

[0035] 6. After processing, turn off the first motor 7, the second motor 23 and the external air source. Move the support 6 to disengage the conveying pipe 5 from the water chestnut pot 4 and the frame 1. Then open the small front door 56 and use the locking block to lock the discharge hopper 74 onto the flange ring 55. Start the screw 48 and the lifting machine 38 to drive the water chestnut pot 4 to swing downwards so that the opening of the water chestnut pot 4 is aligned with the discharge hopper 74. Then the third motor 40 reverses to drive the water chestnut pot 4 and the guide plate 67 to reverse. The material is lifted by the guide plate 67 to the opening of the water chestnut pot 4 and discharged through the discharge hopper 74.

[0036] 7. After the material is discharged, remove the discharge hopper 74 and close the small front door 56. Water is supplied to the first cleaning pipe 27. The water flows through the cleaning ball 28 to spray and clean the inner wall of the enclosed space and the outer wall of the water chestnut pot 4. At the same time, the second cleaning pipe 29 is connected to the hose and the cleaning ball 28. The hose and the cleaning ball 28 are inserted into the water chestnut pot 4 through the third through hole 22 to clean the inner wall of the water chestnut pot 4. Then, the third motor 40 reverses to drive the water chestnut pot 4 and the guide plate 67 to reverse. The sewage is lifted by the guide plate 67 to the opening of the water chestnut pot 4 and flows out. The sewage flows to the bottom water collection tray 30. The valve can be opened to discharge it from the outlet pipe.

[0037] In this embodiment, after the side door 3 is closed, it forms a closed space with the chamber 2. The water chestnut pot 4 works in the closed space, effectively avoiding dust pollution of the processing environment. The powder is sprinkled into the water chestnut pot 4 through the powder-sprinkling structure, which has a high degree of automation, reduces the intensity of manual labor, and the powder is sprinkled more evenly, saving powder. The angle of the water chestnut pot 4 can be adjusted according to the different needs of different products, making it more adaptable. The spiral conveying shaft 11 of the hollow structure 19 and the multi-outlet air hole 21 can not only blow away the clumps of powder, but also blow the powder out from the transverse discharge hole 18, achieving the effect of powdering, so that the powder is sprinkled more evenly on the material in the water chestnut pot 4. The right end of the transverse discharge hole 18 opens to the inner end of the discharge cover to prevent the formation of dead corners for material accumulation. Rotating the rocker arm 50 drives the lead screw 48 to rotate, causing the nut 49 and connecting rod to move up and down, which in turn drives the platform 46 and the structure on the platform 46 to move up and down, allowing the conveying pipe 5 to be inserted into the third through hole 22 and the water chestnut pot 4 at different heights, making it more versatile. The guide rod 53 makes the platform 46 move up and down more stably, and the structure is more stable. The small front door 56 can be opened and the discharge hopper 74 can be installed for material discharge. The small front door 56 and the viewing window 57 can be opened to adjust the position of the spray gun 63. The liquid pipe 64 and multiple air pipes 65 facilitate connection to external liquid and air inlets. The multiple air pipes 65 can be used as spares, making it more versatile. The side doors 3 facilitate the assembly and later maintenance of the water chestnut pot 4.
