[0002] The disc dryer is a high-efficiency, energy-saving, and environmentally friendly conductive continuous drying equipment.

[0003] In existing disc dryers, the rake blades are mostly directly welded or fixed to the mixing rod with a large number of bolts. After a period of use, the disassembly of the rake blades is quite cumbersome when performing maintenance. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a material turning mechanism for a disc dryer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A material turning mechanism for a disc dryer includes a disc dryer body, in which multiple drying discs are installed at equal intervals, and a rotating shaft is set through the center of the multiple drying discs in the disc dryer body. The rotating shaft is driven by a servo motor, and a rake assembly is set on the outer wall of the rotating shaft above the adjacent drying discs through a bearing assembly. The material rake assembly includes a mounting ring, and multiple stirring rods are installed at equal intervals on the outer wall of the mounting ring. A material turning assembly is sleeved on the outside of the stirring rods. The material turning assembly includes a connecting pipe, and multiple mounting frames are sleeved at equal intervals on the outer wall of the connecting pipe. A rake blade body is magnetically attracted to one side of the mounting frame, and an mounting assembly is provided at the upper center of the rake blade body.

A locking groove is provided within the mounting frame at the limiting member, and a mounting hole is provided within the mounting frame at the screw portion.

[0007] In addition, a preferred structure is that an auxiliary component is provided on the mounting frame at the mounting hole, and the bottom end of the auxiliary component has a cavity at both the screw part and the nut part, and T-shaped limiting blocks are symmetrically installed on both sides of the bottom end of the auxiliary component.

[0009] Furthermore, in a preferred configuration, positioning rods are symmetrically installed at both ends of the stirring rod, and a limiting ring is screwed onto one side of the stirring rod. An installation groove is provided on one side of the limiting ring at the stirring rod, and an external thread is provided in the installation groove. An internal thread is provided on the outer wall of the stirring rod away from the installation ring and at the external thread, and the internal thread is threadedly connected to the external thread.

[0010] In addition, a preferred structure is that magnetic blocks are symmetrically embedded at the top of the rake blade body and on both sides of the limiting member, and a groove is opened below the mounting frame at the rake blade body, with a magnetic material on the inner wall of the groove that attracts the magnetic blocks.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-6A material turning mechanism for a disc dryer includes a disc dryer body 1, a plurality of drying discs 2 are installed at equal intervals inside the disc dryer body 1, and a rotating shaft is set through the center of the plurality of drying discs 2 inside the disc dryer body 1. The rotating shaft is driven by a servo motor, and a rake assembly 3 is set on the outer wall of the rotating shaft above the adjacent drying discs 2 through a bearing assembly. Meanwhile, it is worth noting that the specific structure, connection method and working principle of the disc dryer body 1, drying disc 2, rotating shaft and servo motor are all existing technologies that are currently publicly available on the market, so they will not be elaborated further.

[0016] The material rake assembly 3 includes a mounting ring 31, and multiple stirring rods 35 are installed at equal intervals on the outer wall of the mounting ring 31. A material turning assembly 32 is sleeved on the outside of the stirring rods 35. The material turning assembly 32 includes a connecting pipe 321, and multiple mounting frames 322 are sleeved at equal intervals on the outer wall of the connecting pipe 321. A rake blade body 34 is magnetically attracted to one side of the mounting frame 322. An installation component is provided at the middle of the upper part of the rake blade body 34. The rake blade body 34 and the mounting frame 322 are limited by the installation component.

[0017] Meanwhile, the mounting components include a limiting member 341, a screw part 342 is provided on the limiting member 341, and a nut is screwed onto the outside of the screw part 342. A locking groove is provided in the mounting frame 322 at the limiting member 341, and a mounting hole is provided in the mounting frame 322 at the screw part.

[0018] Furthermore, an auxiliary component 36 is provided on the mounting frame 322 at the mounting hole. The bottom end of the auxiliary component 36 has cavities at both the screw part 342 and the nut. T-shaped limit blocks are symmetrically installed on both sides of the bottom end of the auxiliary component 36.

[0019] Furthermore, a movable cavity is provided inside the mounting frame 322 at the T-shaped limiting block, and inlet and outlet slides are provided on both sides of the top of the mounting frame 322 at the T-shaped limiting block, with the bottom of the inlet and outlet slides connecting with the movable cavity.

[0020] Furthermore, positioning rods are symmetrically installed at both ends of the stirring rod 35, and a limiting ring 33 is screwed to one side of the stirring rod 35. An installation groove is opened on one side of the limiting ring 33 at the stirring rod 35, and an external thread is provided in the installation groove. An internal thread is provided on the outer wall of the stirring rod 35 away from the installation ring 31 and at the external thread. The internal thread is threadedly connected to the external thread.

[0021] Furthermore, magnetic blocks 343 are symmetrically embedded at the top of the rake blade body 34 and on both sides of the limiting member 341, and a groove is opened below the mounting frame 322 at the rake blade body 34, with magnetic material adsorbed to the magnetic blocks 343 on the inner wall of the groove.

[0022] In this embodiment, the nut is loosened and removed, and the rake blade body 34 is attracted to the magnetic groove at the bottom of the mounting frame 322 by the magnetic block 343 at the top, so that the rake blade body 34 is initially installed. At this time, one end of the screw part 342 passes through the mounting hole and is tightened with the nut thread, thereby further limiting the position of the rake blade body 34 and ensuring the stability of the installation of the rake blade body.

[0023] Meanwhile, the limiting component 341 is embedded in the locking groove of the mounting frame 322, which not only prevents the rake blade from rotating during installation, but more importantly, after mechanical fastening, it can effectively resist the tangential force and material mixing resistance of the rake blade, preventing the rake blade from sliding or twisting relative to the frame.

[0024] Furthermore, the positioning rods at both ends of the stirring rod 35 and the limiting rings 33 connected by threads work together to firmly lock the connecting pipe 321 and the corresponding material turning assembly 32 on the stirring rod in an axial direction, preventing them from moving along the stirring rod in an axial direction.

[0025] Furthermore, the rake blade body 34 and the mounting frame 322 are connected as a relatively independent unit via a mounting assembly. This design allows individual rake blades or the entire turning assembly 32 to be disassembled independently without disassembling the entire stirring rod 35 or the rotating shaft. When a rake blade is damaged or worn, only that rake blade or the turning assembly can be replaced, greatly reducing maintenance time and costs.

[0026] In this invention, the material turning component 32, the limiting ring 33, the rake blade body 34, the installation component and the magnetic block 343 are arranged in a coordinated manner to allow for quick disassembly and assembly of a single rake blade or material turning component in the disc dryer, and facilitates subsequent maintenance.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
