Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and more specifically, to a blade-type stirring blade for a granulator. Background Technology

[0002] A granulator is an industrial device that uses pressure and friction to shape powdery or granular raw materials into uniform granules or solid particles. Granulators offer advantages such as improved raw material utilization, enhanced product properties, ease of operation and control, and a wide range of applications. Before granulation, various materials are mixed and stirred.

[0003] A search revealed a utility model patent with publication number CN219701848U, which discloses a granulation device for fertilizer production. The device includes a mixing mechanism for blending materials, a granulation mechanism for extruding the mixture, and a movable base for supporting the granulation and mixing mechanisms. The mixing mechanism includes a mixing drum and a mixing device; the mixing device includes a motor, a mixing shaft, and mixing blades; it also includes an anti-clogging structure comprising an extension shaft and spiral blades. The extension shaft is connected to the mixing shaft, and its free end extends downward to the second feed inlet of the granulation mechanism. The spiral blades are mounted on the extension shaft. This patent avoids clogging at the bottom of the mixing drum by providing spiral mixing blades, and the spiral mixing blades accelerate material transport, thereby improving granulation efficiency. However, the aforementioned patent has the following shortcomings: the mixing blades are not convenient for scraping and cleaning materials adhering to the inner wall of the mixing drum, affecting the mixing effect. Therefore, we propose a blade-type mixing blade for a granulator. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a blade-type stirring blade for a granulator.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A blade-type stirring blade for a granulator includes a granulation cylinder, a stirring cylinder fixedly connected to the granulation cylinder, a bearing fixedly sleeved on the top of the stirring cylinder, an agitator column fixedly sleeved on the inner side of the bearing, the bottom end of the agitator column extending to the bottom of the inner cavity of the stirring cylinder and fixedly connected to a spiral guide blade, a square groove formed on the top surface of the agitator column, multiple moving grooves formed on the side of the agitator column and located in the inner cavity of the stirring cylinder, a square column movably sleeved in the inner cavity of the square groove, multiple stirring plates fixedly connected to the side of the square column, the ends of the multiple stirring plates respectively extending through the moving grooves into the inner cavity of the stirring cylinder and fixedly connected to scrapers, the ends of the scrapers fitting against the inner wall of the stirring cylinder, a second gear fixedly sleeved on the outer side of the top of the agitator column, and a drive mechanism provided on the top of the stirring cylinder.

[0007] In a preferred embodiment of this utility model, the driving mechanism includes a U-shaped frame fixedly connected to the top surface of the mixing drum and a servo motor fixedly installed on the top surface of the mixing drum. The output shaft of the servo motor is fixedly sleeved with a first gear, and the first gear and a second gear mesh with each other. The output shaft of the servo motor is fixedly connected with a reciprocating lead screw. The top end of the reciprocating lead screw is rotatably connected to the top of the U-shaped frame. A lifting plate is threaded onto the outer side of the reciprocating lead screw. A rotating column is rotatably connected to the end of the lifting plate. The bottom end of the rotating column is connected to the top end of a square column.

[0008] As a preferred embodiment of this utility model, a material injection pipe is provided at the top of the mixing cylinder.

[0009] In a preferred embodiment of this utility model, multiple stirring rods are fixedly connected to both the top and bottom surfaces of the stirring plate.

[0010] In a preferred embodiment of this utility model, the side of the square column and the inner wall of the square groove are fitted together.

[0011] In a preferred embodiment of this utility model, the inner side of the U-shaped frame and the side of the lifting plate are in contact.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] (1) In this utility model, after various materials are loaded into the mixing drum from the injection pipe, the first gear is driven to rotate by the servo motor. The meshing transmission between the first gear and the second gear drives the stirring column, square column, stirring plate, scraper and stirring rod to rotate synchronously. The stirring plate and stirring rod are used to stir and mix the materials in the inner cavity of the mixing drum. The scraper is used to scrape the materials attached to the inner wall of the mixing drum to ensure the quality of material mixing. It has good practicality.

[0014] (2) In this utility model, the reciprocating screw is driven to rotate by the servo motor. The screw thread between the reciprocating screw and the lifting plate drives the lifting plate, rotating column, square column, stirring plate, scraper and stirring rod to move up and down repeatedly, thereby changing the height of the stirring rod and stirring plate on the material in the stirring drum. At the same time, the height of the scraper on the material in the inner wall of the stirring drum is changed, ensuring that the material in the stirring drum is fully mixed and improving the working quality of the blade-type stirring blade of the granulator.

[0027] For details, please refer to Figures 1 to 4 The drive mechanism 19 includes a U-shaped frame 12 fixedly connected to the top surface of the mixing drum 2 and a servo motor 13 fixedly installed on the top surface of the mixing drum 2. The output shaft of the servo motor 13 is fixedly sleeved with a first gear 18. The first gear 18 and the second gear 17 mesh with each other. The output shaft of the servo motor 13 is fixedly connected with a reciprocating screw 14. The top end of the reciprocating screw 14 is rotatably connected to the top of the U-shaped frame 12. The outer side of the reciprocating screw 14 is threaded with a lifting plate 15. The end of the lifting plate 15 is rotatably connected with a rotating column 16. The bottom end of the rotating column 16 is connected to the top end of the square column 8.

[0028] For details, please refer to Figures 1 to 4 A material injection pipe 20 is provided at the top of the mixing drum 2.

[0029] In this embodiment, the material is put into the inner cavity of the mixing drum 2 through the injection pipe 20.

[0030] For details, please refer to Figure 4 and Figure 5 Multiple stirring rods 11 are fixedly connected to the top and bottom surfaces of the stirring plate 9.

[0031] In this embodiment, the stirring rod 11 is used to ensure the agitation of the material in the stirring drum 2.

The scraper 10 scrapes the material off the inner wall of the mixing drum 2 to ensure that the material is fully mixed. In addition, the reciprocating screw... The threaded connection between the lifting plate 14 and the lifting plate 15 drives the lifting plate 15, rotating column 16, square column 8, stirring plate 9, scraper 10 and stirring rod 11 to move up and down reciprocally, thereby adjusting the height of the stirring plate 9 and stirring rod 11 in stirring the material, and at the same time changing the height of the scraper 10 in scraping the material on the inner wall of the mixing drum 2, thereby cleaning the material at different heights on the inner wall of the mixing drum 2. In addition, when the stirring column 4 rotates, it drives the spiral guide blade 7 to rotate synchronously. Through the rotation of the spiral guide blade 7, the material is guided from the inner cavity of the mixing drum 2 into the granulation drum 1 for granulation.
