Description

Technical Field

[0001] This utility model relates to the field of rotary dryer technology, and in particular to a rotary dryer with a material distribution mechanism. Background Technology

[0002] A rotary dryer, also known as a rotating drum dryer, is a widely used industrial drying device that uses continuous, indirect, or direct heating. A rotary dryer typically consists of coaxially arranged rotating drums, inside which are equipped with helical blades and intermittent helical lifting plates. The material is propelled by the helical blades and lifted by the intermittent helical lifting plates within the drum, oscillating between the inner and outer drums while simultaneously exchanging heat thoroughly with the heating medium, thus achieving the drying purpose.

[0003] The feed inlet of some existing rotary dryers is usually just a "channel" and most of them do not have a special structure for breaking down and crushing. For some materials that are prone to caking or lumpy materials formed due to transportation and storage, the material enters the cylinder directly in the form of lumps through the feed inlet, which can easily lead to material accumulation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotary dryer with a material distribution mechanism.

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

An auxiliary feed pipe is connected to the feed inlet via a fastening assembly. A support base is installed at the top center of the auxiliary feed pipe. A rotating shaft is connected to the bottom of the support base via a bearing assembly. The rotating shaft is driven by a drive unit. A dispersing component is sleeved on the outer wall of one end of the rotating shaft. The dispersing component includes a mounting ring. Multiple dispersing blades are installed at equal intervals on the outer wall of the mounting ring. Multiple detachable dispersing rods are arranged at equal intervals on the side of the dispersing blades near the drive unit.

[0007] A guide block is installed in the lower middle part of the auxiliary feed pipe. The top of the guide block has an inclined surface from the middle to both ends, and multiple dispersing cones are installed on the guide block at equal intervals.

[0008] In addition, a preferred structure is that auxiliary guide blocks are installed at all four corners of the auxiliary feed tube, and one end of the auxiliary guide block is attached to the outer side of the adjacent guide block, and the top of the auxiliary guide block is provided with an inclined surface facing the middle of the auxiliary feed tube.

[0009] In addition, a preferred structure is that multiple guide plates are installed at equal intervals on the auxiliary guide block, and the top of each guide plate has an inclined surface from the middle to both ends.

[0021] 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.

[0022] Reference Figure 1-5 A rotary dryer with a material distribution mechanism includes a rotary dryer body 1, a feed inlet 2 on the rotary dryer body 1, an auxiliary feed pipe 3 connected to the feed inlet 2 by a fastening assembly, a support base installed at the top center of the auxiliary feed pipe 3, and a rotating shaft 41 connected to the bottom of the support base by a bearing assembly. The rotating shaft 41 is driven by a drive unit 4, and a dispersing component 42 is sleeved on the outer wall of one end of the rotating shaft 41. The dispersing component 42 includes a mounting ring, and multiple dispersing blades 421 are installed at equal intervals on the outer wall of the mounting ring. Multiple detachable dispersing rods 424 are arranged at equal intervals on the side of the dispersing blades 421 near the drive unit 4. The mounting ring is fixed to the rotating shaft 41 by a keyway or a set screw.

[0023] A guide block 5 is installed in the lower middle part of the auxiliary feed pipe 3. The top of the guide block 5 has an inclined surface from the middle to both ends, and multiple dispersing cones 51 are installed on the guide block 5 at equal intervals.

[0024] Furthermore, auxiliary guide blocks 6 are installed at the four corners of the auxiliary feed pipe 3, and one end of the auxiliary guide block 6 is attached to the outer side of the adjacent guide block 5. The top of the auxiliary guide block 6 is provided with an inclined surface facing the middle of the auxiliary feed pipe 3.

[0025] Furthermore, multiple guide plates 61 are installed at equal intervals on the auxiliary guide block 6, and the top of each guide plate 61 has an inclined surface from the middle to both ends.

[0026] Meanwhile, multiple extension seats 422 are installed at equal intervals on the side of the dispersing blades near the drive unit 4. Magnetic positioning blocks 423 are fixedly installed on the extension seats 422, and dispersing rods 424 are fitted around the magnetic positioning blocks 423. The dispersing rods 424 are connected to the extension seats 422 by multiple bolts. A fixing ring is installed on the outside of the dispersing rods 424 near the magnetic positioning groove. The outer diameter of the fixing ring is the same as the outer diameter of the extension seats 422, and a sealing gasket (not shown in the figure) is fixedly embedded on the outside of the fixing ring near the magnetic positioning groove. Multiple mounting holes are opened at equal intervals inside the fixing ring.

[0027] Meanwhile, a magnetic positioning groove is provided inside the dispersing rod 424 at the magnetic positioning block 423, and a magnetic material that attracts the magnetic positioning block 423 is provided in the magnetic positioning groove.

[0028] Furthermore, a support frame is provided inside the auxiliary feed pipe 3 and above the guide block 5. The support frame is fixed to the inner wall of the auxiliary feed pipe 3 by a support rod, and the bottom end of the rotating shaft 41 is connected to the support frame through a bearing assembly.

[0029] It is worth noting that the specific structure, connection method, and working principle of the rotary dryer body 1 and the drive unit are all existing technologies that are currently publicly available on the market, so they will not be described in detail. At the same time, the support base is equipped with a dustproof component on the outer cover of the drive unit, and the shaft penetration part, the connection between the auxiliary feed pipe and the rotary dryer body are all sealed (not shown in detail in the figure). Furthermore, the specific model and specifications of the drive unit need to be selected and determined according to the actual specifications of the device. The power supply and operating principle of the drive unit are clear to those skilled in the art, so they will not be described in detail.

[0030] In this embodiment, materials are fed into the auxiliary feed pipe 3 through the support base on both sides, and the drive unit 4 is controlled to drive its rotating shaft 41 and the dispersing component 42 to rotate. The bottom of the shaft 41 is supported by the support frame to ensure the stability of the rotating shaft 41 during rotation.

[0031] During the rotation of the dispersing component 42, the falling material is dispersed and crushed by the dispersing blades 421 and the dispersing rods 424.

[0032] Meanwhile, the broken material falls onto the top of the guide block 5 or the auxiliary guide block 6. The guide block 5 diverts the material from both sides of the initially crushed material box to prevent it from accumulating in the center. During the diversion process, the material impacts the tip of the breaking cone 51 under the action of centrifugal force and is further broken down.

[0033] Furthermore, the material diverted to both sides reaches the top of the auxiliary guide block 6, and is further broken up and crushed by the guide plate 61.

[0034] Meanwhile, the disintegrating rod 424 is detachable. When any of the disintegrating rods 424 is worn, it can be disassembled for maintenance or replacement. The disintegrating rod 424 can be disassembled by loosening the threaded bolts.

[0035] After maintenance or replacement, align the magnetic positioning groove of the dispersing rod 424 with the magnetic positioning block 423, insert it and magnetically attract it. Then, align the mounting hole with the mounting bolt and drive it in to complete the installation of the dispersing rod 424.

[0036] In this utility model, the material entering the auxiliary feed pipe 3 is broken down and crushed by the coordinated arrangement of the dispersing component 42, the rotating shaft 41, and the drive unit 4. At the same time, the material is guided and diverted by the coordinated arrangement of the guide plate 5, multiple dispersing cones 51, auxiliary guide blocks 6, and guide plates 61, which also play a certain role in auxiliary dispersing and crushing.

[0037] 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.
