Description

Technical Field

[0001] The utility model relates to the technical field of powder processing, in particular to a high-efficiency powder drying device. Background Art

[0002] Powder materials are common in production and life. For the drying process of powder materials, dryers are often used for high-temperature drying. However, due to the small particle size of powder materials, when more powder materials are stacked together for drying, the powder located in the center of the powder pile is not easy to be dried, resulting in the need for manual stirring of the powder during the powder drying process, which leads to dust, waste of materials, harm to operators, and waste of more manpower and material resources. At the same time, manual stirring of powder materials cannot ensure that the first dried material and the undried material are mixed evenly, resulting in uneven moisture content of the dried powder, affecting the use of the material, and usually requires the use of a drying device for drying.

[0003] For example, the utility model patent with authorization announcement number CN214950260U discloses a powder drying device, which is provided with a plurality of horizontally arranged pipes. Hot water circulates in the pipes to increase the temperature inside the box, facilitate drying of the material inside the box, and help the material to be heated evenly, thereby improving the drying efficiency and drying quality of the material.

[0004] However, when the device is used, the powder cannot be turned over well, resulting in uneven heating of the powder. At the same time, it is inconvenient to discharge the powder, which reduces the practicality of the device and cannot meet the use requirements well. Utility Model Content

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment: Please refer to Figures 1 to 5 , an efficient powder drying device, including: a base 1, a pair of drying racks 11 are installed on the base 1, a drying cylinder 13 is rotatably installed between the drying racks 11 through a slewing bearing, a cylinder cover 14 is detachably installed at the upper end of the drying cylinder 13, a feed hopper 15 is further installed at the upper end of the cylinder cover 14, a sealing cover 16 is screwed at the end of the feed hopper 15, a hexagonal knob 17 is fixed at the upper end of the sealing cover 16, and a receiving box 12 is also placed on the upper end of the base 1; a turning mechanism 2, installed in the drying cylinder 13, for turning the powder in the drying cylinder 13; a drying mechanism 5, installed on the drying cylinder 13, for heating and drying the powder in the drying cylinder 13; a tipping mechanism 3, installed on the drying cylinder 13, for driving the drying cylinder 13 to rotate; a limiting mechanism 4, installed between the drying rack 11 and the drying cylinder 13, for limiting the drying cylinder 13.

[0025] Working principle of the utility model: During specific use, powder to be dried is added into the drying cylinder 13 through the feed hopper 15, and then the cover 16 is screwed on. Subsequently, the powder in the drying cylinder 13 is dried by the heating mechanism 5. Immediately afterwards, the powder in the drying cylinder 13 is turned by the turning mechanism 2 to make it more evenly heated, so as to complete the drying work more efficiently. After drying is completed, the drying cylinder 13 is driven by the tipping mechanism 3 to rotate 180°, so that the opening of the feed hopper 15 faces a certain direction. Then the cover 16 is unscrewed, and the dried powder can be poured out and fall into the receiving box 12 to complete the collection work. The operation is simple and convenient for tipping, and can better meet the use requirements.

[0026] As a further solution, the turning mechanism 2 includes a turning rotating shaft 22 rotatably installed in the drying cylinder 13. Spiral turning paddles 23 are installed on both the left and right sides of the turning rotating shaft 22. The spiral turning paddles 23 on the left and right sides have opposite rotation directions. A turning motor 21 is also installed at the end of the drying rack 11. The output end of the turning motor 21 is drivingly connected to the shaft end of the turning rotating shaft 22.

[0027] The working principle of the turning mechanism 2 is as follows: When turning, the turning motor 21 is started, and the turning rotating shaft 22 is driven by the turning motor 21 to rotate forward, so that the spiral turning paddles 23 on both sides push the powder in the middle position to both sides. By driving the turning rotating shaft 22 to rotate reversely by the turning motor 21, the powder on both sides can be pushed to the middle position. Repeating this process can better turn the powder, make the powder more evenly heated, improve the drying effect, and thus complete the drying work more efficiently.

[0028] As a further solution, the drying mechanism 5 includes a drying groove 51 opened at the lower end of the drying cylinder 13. A number of electric heating tubes 52 are distributed and installed in the drying groove 51. A drying cover plate 53 is also installed outside the drying groove 51. In this embodiment, the drying cover plate 53 is a heat-insulating plate.

[0029] The working principle of the drying mechanism 5 is as follows: When drying, the electric heating tubes 52 work, and the drying cylinder 13 can be heated, so as to realize the heating and drying work of the powder inside the drying cylinder.

[0030] As a further solution, the tipping mechanism 3 includes tipping gear rings 31 installed on both the left and right sides of the drying cylinder 13. A tipping rotating shaft 33 is rotatably installed between the drying racks 11. A pair of tipping gears 34 are installed on the tipping rotating shaft 33. The tipping gears 34 are meshed with the corresponding tipping gear rings 31. A tipping motor 32 is also installed on the drying rack 11. The output end of the tipping motor 32 is drivingly connected to the shaft end of the tipping rotating shaft 33.

[0031] The working principle of the material discharging mechanism 3 is as follows: when discharging materials, start the discharging motor 32, drive the discharging gear 34 to rotate through the discharging motor 32, thereby driving the discharging gear ring 31 engaged and connected with it to rotate, and then realizing the rotation of the drying cylinder 13, so that the feeding hopper 15 rotates, making its opening face downward, and then rotating towards the cover 16, and the powder can be poured out.

[0032] As a further solution, the limiting mechanism 4 includes a first limiting block 41 installed on the discharging gear ring 31, and a second limiting block 42 is also installed on the drying rack 11.

[0033] By setting the limiting mechanism 4, after the discharging mechanism 3 drives the drying cylinder 13 to rotate 180°, the second limiting block 42 blocks the first limiting block 41 to prevent the continuous rotation of the drying cylinder 13, making the opening of the feeding hopper 15 face downward, which is convenient for pouring out the powder in the drying cylinder 13.
