Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a rotary screen dryer. Background Technology
[0002] A rotary screen dryer is a device that uses the rotation of a drum and a built-in screen to stir, crush, and introduce hot air to achieve efficient drying of wet materials. It is widely applicable to the rapid dehydration of granular or small block materials.
[0003] Existing rotary screen dryers are prone to screen clogging, requiring frequent cleaning and maintenance; wet materials are also prone to clumping in existing rotary screen dryers, affecting product quality.
[0004] When processing wet materials, the screening drum of the existing equipment is easily clogged by sticky materials. This not only reduces screening efficiency but also requires frequent shutdowns for manual cleaning, which seriously affects continuous production. For materials containing moisture, the existing equipment is prone to causing the material to clump on the inner wall of the equipment due to residual moisture during the drying process. These clumps are not only not dried thoroughly themselves but also affect the flow of other materials and heat exchange, ultimately resulting in inconsistent dryness and unstable quality of the finished product. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a rotary screen dryer.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rotary screen dryer, comprising a rotary screen drying mechanism, wherein a fixed cover is fixedly connected to one side of the rotary screen drying mechanism; a support frame is fixedly connected to the outer side of the rotary screen drying mechanism; an electric switch valve is fixedly connected to the bottom end of the rotary screen drying mechanism; a control structure is fixedly connected to one side of the support frame; and a second power structure is fixedly connected to the side of the support frame adjacent to the control structure.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] This invention achieves efficient material screening and uniform drying through a rotary screen drying mechanism and a built-in rotary screening structure.

This prevents clumping and uneven drying caused by residual moisture, ensuring product drying quality. The combination of baffles and a slight tilt of the entire machine enables step-by-step screening and sufficient retention of materials within the drum, improving screening accuracy and processing efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1
[0032] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a rotary screen dryer, including a rotary screen drying mechanism 1, a fixed cover 2 fixedly connected to one side of the rotary screen drying mechanism 1; a support frame 4 fixedly connected to the outer side of the rotary screen drying mechanism 1, an electric switch valve 6 fixedly connected to the bottom end of the rotary screen drying mechanism 1, a control structure 5 fixedly connected to one side of the support frame 4, and a power structure 3 fixedly connected to the side of the support frame 4 adjacent to the control structure 5.
[0033] A rotating screening structure 15 is rotatably connected to the inner side of the drying shell 11. The rotating screening structure 15 includes a screening drum 151. A rotating cleaning brush 152 is provided on the outer side of the screening drum 151. A rotating rod 154 is fixedly connected to the inner side of the rotating cleaning brush 152. A connecting support structure 153 is rotatably connected to the outer side of one end of the rotating rod 154. A rotating rod 155 is rotatably connected to the inner side of the connecting support structure 153 away from the rotating rod 154. A rotating rod 156 is fixedly connected to the outer side of the rotating rod 155. A scraper 157 is fixedly connected to the outer side of the rotating rod 156. A baffle 159 is fixedly connected to the inner side of the screening drum 151. The bottom of the connecting support structure 153... A power structure 158 is fixedly connected to the end of the motor. The power structure 158 includes a motor 1581. The output end of the motor 1581 is fixedly connected to a two-drive rotating mechanism 1584. The output end of the two-drive rotating mechanism 1584 is fixedly connected to a rotating rod 154. The other output end of the two-drive rotating mechanism 1584 is fixedly connected to a rotating rod 155. The bottom end of the motor 1581 is fixedly connected to a fixing structure 1582. The bottom end of the fixing structure 1582 is fixedly connected to a support structure 1583. The outside of the support structure 1583 is fixedly connected to a support structure 1585. The top end of the support structure 1585 is fixedly connected to the bottom end of the support structure 153.
[0034] In this embodiment, starting the motor 1581 activates the dual-rotation mechanism 1584, which is fixedly connected to the output of the motor 1581. This causes the rotating rods 154 and 155, both fixedly connected to the output of the dual-rotation mechanism 1584, to rotate. This, in turn, causes the rotating rod 156, fixedly connected to the rotating rod 155, to rotate. Consequently, the scraper 157, rotatably connected to the rotating rod 156, rotates, thus scraping off the product adhering to the inner side of the screening drum 151. This, in turn, causes the scraper 157, rotatably connected to the rotating rod 1581, to rotate. The fixedly connected rolling cleaning brush 152 rotates to wash away the product in the aperture of the screening drum 151. The rolling cleaning brush 152 and the rotating rod 156 rotate in the same direction, but in a different direction than the screening drum 151, thus achieving the effect of completely drying the product and avoiding the problem of product adhesion caused by the presence of moisture, and avoiding the problem of uneven drying caused by product adhesion. The support structure 1585 and the connecting support structure 153 work together to support the rolling cleaning brush 152 and the rotating rod 156.
[0035] Example 2
[0036] like Figure 1 - Figure 7 As shown, the power structure 2 3 includes a motor 2 31, a gear 34 is fixedly connected to the output end of the motor 2 31, a fixed structure 2 32 is fixedly connected to the bottom end of the motor 2 31, a support structure 3 33 is fixedly connected to the bottom end of the fixed structure 2 32, the bottom end of the support structure 2 1585 and the top end of the support structure 3 33 are fixedly connected, the outer side of the gear 34 is meshed with the toothed end of the screening drum 151, a support structure 4 35 is fixedly connected to one side of the bottom end of the support structure 3 33, and the outer side of the support structure 3 33 is fixedly connected to the side of the support frame 4 near the control structure 5.
[0037] The rotary screen drying mechanism 1 includes a drying shell 11. A rotating connecting key 12 is fixedly connected to the outside of the drying shell 11. A flip cover 13 is rotatably connected to the outside of the rotating connecting key 12. A fixing piece 14 is also fixedly connected to the outside of the drying shell 11. A quick-release key 16 is fixedly connected to the outside of the fixing piece 14. A fixing piece 27 is fixedly connected to the outside of the flip cover 13. The fixing cover 2 includes a protective cover 21. An inlet 22 is fixedly connected to the outside of the protective cover 21. The side of the protective cover 21 away from the inlet 22 is fixedly connected to the drying shell 11. The end of the rotating rod 154 away from the connecting support structure 153 is rotatably connected to the protective cover 21. The end of the rotating rod 255 away from the connecting support structure 153 is rotatably connected to the protective cover 21.
[0038] In this embodiment,
[0039] The motor 31 is started, causing the gear 34, which is fixedly connected to the output end of the motor 31, to rotate. This, in turn, causes the rolling screening structure 15, which is meshed with the gear 34, to rotate, thereby achieving the effect of rotational screening. The rolling screening structure 15 is provided with holes of different diameters. The entire invention is inclined at a certain angle to the horizontal plane from the feed inlet 22 to the coarse hole screen to facilitate product screening. The connection between the drying shell 11 and the rolling screening structure 15 adopts the rotational connection of the prior art. The baffle 159 is provided to make the product screening more complete and prevents the product from entering the next screening point without stopping due to the inclination of the angle.
[0040] The drying process of this utility model is controlled by the control structure 5. The collection of products with different apertures is achieved by the electric switch valve 6. The support frame 4 provides support. The flip cover 13 is flipped by the rotation connection key 12. The flip cover 13 can be quickly fixed and separated from the drying shell 11 by the quick release key 16.
[0041] Working principle:
[0042] like Figure 1 - Figure 7 As shown, the motor 1581 is started, which in turn starts the rotating mechanism 1584 fixedly connected to the output end of the motor 1581. This causes the rotating rod 154 and rotating rod 155 fixedly connected to the output end of the rotating mechanism 1584 to rotate, which in turn causes the rotating rod 156 fixedly connected to the rotating rod 155 to rotate, which in turn causes the scraper 157 fixedly connected to the rotating rod 156 to rotate. This scrapes off the product attached to the inside of the screening drum 151, and causes the rolling cleaning brush 152 fixedly connected to the rotating rod 154 to rotate, thereby washing away the product in the aperture of the screening drum 151.
[0043] The motor 31 is started, causing the gear 34, which is fixedly connected to the output end of the motor 31, to rotate. This, in turn, causes the rolling screening structure 15, which is meshed with the gear 34, to rotate, thereby achieving the effect of rotational screening. The rolling screening structure 15 is provided with holes of different diameters. The entire invention is inclined at a certain angle to the horizontal plane from the feed inlet 22 to the coarse hole screen to facilitate product screening. The connection between the drying shell 11 and the rolling screening structure 15 adopts the rotational connection of the prior art. The baffle 159 is provided to make the product screening more complete and prevents the product from entering the next screening point without stopping due to the inclination angle.
[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
