Description

Technical Field

[0001] The utility model relates to the technical field of reduced iron powder drying, in particular to a reduced iron powder drying machine. Background Art

[0002] Reduced iron powder is a gray or black powder mainly containing elemental iron. It is generally produced by reducing ferroferric oxide in a hydrogen or carbon monoxide flow under high heat conditions. It is often used for food preservation. The iron powder dryer is specially used for drying iron powder, iron filings, steel filings, copper filings, etc. The iron powder dryer can achieve degreasing and drying at the same time.

[0003] The existing application number is 202220141715.9, which is a reduced iron powder dryer. It includes a drying drum and a driving mechanism installed on the outside of the drying drum and used to drive the drying drum to rotate. An inner drying drum is fixedly installed on the inner side wall of the drying drum, and a plurality of protruding second heat conducting plates are provided on the inner side wall of the inner drying drum. A hot drying pipe is provided at the middle position inside the drying drum. By arranging the inner drying drum on the inner side of the drying drum and arranging the hot drying pipe at the middle position inside the inner drying drum, the inner drying drum and the hot drying pipe both have cavities inside, which can introduce hot air. At the same time, there is also a first heat conducting plate. The air guide nozzle can spray out hot air, which can keep the entire drying cylinder in a high-temperature heating state, so that the iron powder entering the drying cylinder can replace the contact surface with the heat source, thereby improving the drying speed and increasing the drying efficiency. After the hot air is discharged from the upper end of the drying cylinder, it can also be reused to improve the thermal efficiency. Although the reduced iron powder can be dried by hot air, there is no improvement on the feed end. When the material enters the dryer in piles and blocks, the dryer cannot quickly dry the agglomerated material due to the moisture and agglomeration of the material, which will greatly affect the drying efficiency. Therefore, a reduced iron powder dryer is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a reduced iron powder drying machine to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A dryer is fixedly connected to the top of the base, and a hot air blower fixedly connected to the base is provided on one side of the dryer;

[0008] A feeding mechanism fixedly connected to the base is provided on the other side of the dryer;

[0009] The output end of the feeding mechanism is connected to a dispersion mechanism, and the dispersion mechanism is arranged inside the dryer;

[0010] The feeding mechanism includes a bracket, a hopper and a motor. The bottom of the bracket is fixedly connected to the base, the top of the bracket is fixedly connected to the hopper, the inside of the hopper is fixedly connected to the motor, the end of the main shaft of the motor is fixedly connected to the rotating shaft, and the outer side of the rotating shaft is fixedly connected to rolling rollers distributed up and down, and a filter is provided under each rolling roller.

[0011] The bottom of the rotating shaft is fixedly connected to a rotating column, and the outer side of the rotating column is fixedly connected to evenly distributed conveying blades;

At the same time, the rotating shaft can also drive the rotating column to rotate, and the rotating column drives the conveying blades to rotate. At this time, it can be ensured that the material below is actively transported to the inside of the conveying pipe, and then dispersed and discharged into the dryer through the dispersion mechanism, thereby realizing efficient drying of the reduced iron powder.

[0017] As an optional solution of the reduced iron powder dryer described in the utility model, the lower side of the dispersion frame is arranged in an inclined surface.

[0018] When the reduced iron powder material enters the dispersion frame, under the guidance of the inclined plates, the reduced iron powder material is located between the guide plates and falls from the bottom of the guide plates. At the same time, the bottom of the dispersion frame is inclined, which can ensure that the reduced iron powder material is dispersed and falls, avoiding its accumulation, and effectively ensuring the subsequent drying purpose.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1 and Figure 2 , the utility model provides a technical solution:

[0028] A reduced iron powder dryer, comprising a base 1, a dryer 2 and a hot air blower 3;

[0029] A dryer 2 is fixedly connected to the top of the base 1, and a hot air blower 3 fixedly connected to the base 1 is provided on one side of the dryer 2;

[0030] A feeding mechanism 4 fixedly connected to the base 1 is provided on the other side of the dryer 2;

[0031] The output end of the feeding mechanism 4 is connected to a dispersion mechanism 5, and the dispersion mechanism 5 is arranged inside the dryer 2;

[0032] The feeding mechanism 4 includes a bracket 401, a hopper 402 and a motor 403. The bottom of the bracket 401 is fixedly connected to the base 1, the top of the bracket 401 is fixedly connected to the hopper 402, the interior of the hopper 402 is fixedly connected to the motor 403, the end of the main shaft of the motor 403 is fixedly connected to the shaft 404, and the outer side of the shaft 404 is fixedly connected to the upper and lower rolling rollers 405, and the lower part of the rolling rollers 405 is provided with a filter 406;

[0033] The bottom of the rotating shaft 404 is fixedly connected to a rotating column 407, and the outer side of the rotating column 407 is fixedly connected to evenly distributed conveying blades 408;

[0034] The bottom of the hopper 402 is connected to an inclined conveying pipe 409 , and the other end of the conveying pipe 409 is connected to a dispersing mechanism 5 .

[0035] The outer side of the filter screen 406 is fixedly connected to the bracket 401 , and the inner side of the filter screen 406 is rotatably connected to the rotating shaft 404 .

[0036] The number of the above-mentioned filter screens 406 is multiple groups, and the mesh sizes of the filter screens 406 decrease from top to bottom.

[0037] Although the existing technology can dry the reduced iron powder by hot air, it does not improve the feeding end. When the material enters the dryer in piles and blocks, the dryer cannot quickly dry the agglomerated material due to the moisture and agglomeration of the material, which will greatly affect the drying efficiency. When in use, the power is turned on, the reduced iron powder is put into the hopper 402, and the material falls on the surface of the filter 406. At this time, the material can be filtered in turn, and the provided rolling roller 405 can ensure that the agglomerated material is rolled and crushed. At the same time, the rotating shaft 404 can also drive the rotating column 407 to rotate, and the rotating column 407 drives the conveying blade 408 to rotate. At this time, it can be ensured that the material below is actively conveyed to the inside of the conveying pipe 409, and then dispersed and discharged into the inside of the dryer 2 through the dispersing mechanism 5, thereby achieving efficient drying of the reduced iron powder.

[0038] In this embodiment, when the reduced iron powder material is on the surface of the filter screen 406 above the falling rain, the reduced iron powder material can fall down smoothly, while the larger agglomerated reduced iron powder material is located on its surface. The mesh size of the filter screen 406 decreases from top to bottom. At this time, multiple filter screens 406 can filter reduced iron powder materials of different sizes in turn, realize the dispersion treatment of the agglomerated reduced iron powder material, reduce the burden of the filter screen 406, and facilitate the rolling roller 405 to roll the agglomerated reduced iron powder material to crush it, thereby ensuring the subsequent drying quality.

[0039] Example 2: This example is an improvement on Example 1. Figure 3 Specifically, the above-mentioned dispersion mechanism 5 includes a dispersion frame 501, a guide plate 502 and an inclined plate 503. One side of the above-mentioned dispersion frame 501 is connected to the feeding mechanism 4. The interior of the above-mentioned dispersion frame 501 is fixedly connected with multiple groups of guide plates 502, and the tops of the above-mentioned guide plates 502 on both sides are fixedly connected with inclined inclined plates 503.

[0040] The bottom of the dispersion frame 501 is provided with an inclined surface.

[0041] When the reduced iron powder enters the dispersion frame 501, it is guided by the inclined plate 503 and is located between the guide plates 502. The reduced iron powder falls from the bottom of the guide plates 502. The bottom of the dispersion frame 501 is inclined, which ensures that the reduced iron powder falls and avoids accumulation, thereby effectively ensuring the subsequent drying purpose.

[0042] In this embodiment, the dispersion frame 501 is arranged in a rectangular shape, which can ensure that the materials fall in a dispersed manner, avoid accumulation and fall, ensure the contact area with the hot air, and ensure the drying quality.
