Description

Technical Field

[0001] This utility model relates to the field of drum dryer technology, specifically a high-efficiency scraper drum dryer. Background Technology

[0002] As is well known, the drum scraper dryer is a type of internally heated, conductive, rotating continuous drying equipment.

[0003] Existing rotary drum dryers often have cylindrical drums, which limits their heating contact area. When hanging materials on the drum, it is also necessary to ensure that the scraper fits the drum as a whole. If the scraper is damaged in a part, material leakage will occur, requiring the entire machine to be shut down for maintenance and inspection, disassembly of the scraper, and replacement with a new scraper. This is inefficient and inconvenient to use. Utility Model Content

Both the support frame and the lifting frame are U-shaped with downward openings. The two free ends of the support frame are set on the ground. The dryer body is located inside the support frame. The feeding box, the output pump, and the first cylinder are arranged on the top wall of the support frame. One end of the output pump is connected to the feeding box. The first cylinder passes through the top wall of the support frame and is connected to the top wall of the lifting frame. The diversion pipe is arranged below the lifting frame. Several sets of atomizing nozzles adapted to the groove are arranged below the diversion pipe. The other end of the output pump passes through the support frame and is connected to the diversion pipe through a connecting pipe.

[0009] The heating assembly includes a steam heating pipe, a steam output valve, and a drain pipe. One end of the steam heating pipe passes through a set of frames and extends into the drum body. The steam heating pipe is in the shape of a right-angled Z. One end of the steam heating pipe extending into the drum body is close to the upper wall of the drum body and is provided with several sets of steam output valves that are adapted to the groove. The drain pipe passes through another set of frames and extends into the drum body, contacting the bottom wall of the drum body.

[0010] The scraping assembly is also provided on both sides of the support frame. The scraping assembly includes a main support plate, an auxiliary support plate, a collection port, a hinge plate, and a scraper body. The main support plate and the auxiliary support plate are respectively provided on the upper and lower sides of the collection port. The auxiliary support plate is longer than the main support plate. The main support plate is provided with a hinge plate for supporting several sets of scraper bodies adapted to the groove.

[0011] To facilitate overall control of the atomizing nozzle output, this utility model is improved by providing sliding grooves on the left and right sides of the support frame that are adapted to the side walls of the lifting frame, and a normally open switch for controlling the output of the atomizing nozzle is provided on the bottom wall of the sliding groove.

[0012] To facilitate cleaning of the roller when the feeding stops and the entire scraper body is no longer in contact with the roller, the present invention includes an improvement whereby a gear is provided through the side wall of the support frame on one side of the hinge plate. The support frame also includes an angle adjustment component for controlling the fit between the scraper body and the corresponding groove. The angle adjustment component includes a second cylinder, a rack, and a time delay switch. The support frame has a time delay switch connected to the normally open switch. The second cylinder is located on the outside of the support frame, and its output end has a rack that meshes with the gear. The time delay switch is connected to the second cylinder.

[0013] When a part of the scraper body is damaged, in order to facilitate the repair and inspection of the corresponding scraper body, the present invention is improved by setting the scraper body and the hinge plate to be detachably connected, the hinge plate being T-shaped, and the main support plate being provided with a positioning groove adapted to the end of the hinge plate away from the scraper body.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a high-efficiency scraper drum dryer with the following advantages:

[0020] This high-efficiency scraper drum dryer has several sets of isosceles trapezoidal grooves on the drum body, which are matched with corresponding output atomizing nozzles. The grooves increase the contact area between the material and the drum body. The steam supply pipe with corresponding steam output valve outputs steam that is compatible with the grooves, ensuring heat utilization efficiency and material processing efficiency.

[0021] The scraper body is adapted to the groove, which facilitates the collection of materials over a large area. When the equipment stops, the first cylinder drives the mounting bracket to not contact the normally open switch, the atomizing nozzle stops supplying liquid, the drum body rotates, and after a delay, the hinge plate with the scraper body is controlled to not contact the drum body, which facilitates the cleaning of the drum body and ensures cleaning efficiency.

[0022] The scraper body and the hinge plate are connected separately. When a part of the scraper body is unusable, the corresponding atomizing nozzle stops outputting material, while the other scraper bodies and atomizing nozzles can be used normally. After the material is dried, only the damaged scraper body needs to be repaired, inspected or replaced to ensure processing efficiency. Attached Figure Description

[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] Please see Figure 1-6 A high-efficiency scraper drum dryer includes a dryer body, a liquid supply assembly, a scraping assembly, and a heating assembly. The dryer body includes two sets of symmetrically arranged frames 1 and a drum body 2 rotatably connected to the frames 1. The drum body 2 is provided with several sets of uniformly arranged grooves, and the grooves are in the shape of isosceles trapezoids.

[0032] In this embodiment, the frame 1 provides stable support for the roller body 2, and the isosceles trapezoidal groove on the roller body 2 increases the contact area between the material and the roller body 2, ensuring processing efficiency.

[0033] During liquid supply, the liquid supply assembly includes a support frame 3, a feeding box 4, an output pump 5, a lifting frame 6, a diversion pipe 7, an atomizing nozzle 8, and a first cylinder 9. Both the support frame 3 and the lifting frame 6 are U-shaped with downward openings. The two free ends of the support frame 3 are positioned on the ground, and the dryer body is located inside the support frame 3. The top wall of the support frame 3 is equipped with the feeding box 4, the output pump 5, and the first cylinder 9. One end of the output pump 5 is connected to the feeding box 4. The first cylinder 9 penetrates the top wall of the support frame 3 and is connected to the top wall of the lifting frame 6. The diversion pipe 7 is located below the lifting frame 6. The support frame 3 is equipped with several sets of atomizing nozzles 8 that are adapted to the groove. The other end of the output pump 5 is connected to the support frame 3 and the diversion pipe 7 through a connecting pipe. The atomizing nozzles 8 can also be controlled to open and close by a corresponding switch under special circumstances. Under normal circumstances, the support frame 3 provides stable support for the feeding box 4, the output pump 5 and the first cylinder 9. The first cylinder 9 is connected to the lifting frame 6 with the diversion pipe 7 through the top wall of the support frame 3. The atomizing nozzles 8 below the diversion pipe 7 are adapted to the groove. After the output pump 5 sends the material in the feeding box 4 into the diversion pipe 7, the atomizing nozzles 8 spray the material into the groove to ensure that the material is in uniform contact with the groove.

[0034] In actual use, the heating component includes a steam heating pipe 10, a steam output valve 11, and a drain pipe 12. One end of the steam heating pipe 10 passes through a set of frames 1 and extends into the drum body 2. The steam heating pipe 10 is in the shape of a right angle Z. One end of the steam heating pipe 10 extending into the drum body 2 is close to the upper wall of the drum body 2 and is provided with several sets of steam output valves 11 that are adapted to the groove. The drain pipe 12 passes through another set of frames 1 and extends into the drum body 2, contacting the bottom wall of the drum body 2. The groove part requires the most heat and needs to be evenly distributed. Therefore, the opening size of the corresponding steam output valve 11 of the steam heating pipe 10 is adjusted to evenly distribute the heat supply. The drain pipe 12 drains the condensate in the drum.

[0035] When hanging the dried material, the scraping assembly is also provided on both sides of the support frame 3. The scraping assembly includes a main receiving plate 13, an auxiliary receiving plate 14, a collection port 15, a hinge plate 16, and a scraper body 17. The main receiving plate 13 and the auxiliary receiving plate 14 are respectively provided on the upper and lower sides of the collection port 15. The auxiliary receiving plate 14 is longer than the main receiving plate 13. The main receiving plate 13 is provided with a hinge plate 16 for supporting several sets of scraper bodies 17 that are adapted to the grooves. The hinge plate 16 on the main receiving plate 13 drives the scraper body 17 to extend into the corresponding groove. The material enters the collection port 15 through the scraper body 17, the hinge plate 16, and the main receiving plate 13. Some spilled material is sent into the collection port 15 through the auxiliary receiving plate 14, which facilitates stable and concentrated collection of the material.

[0036] When the liquid supply component stops, the first cylinder 9 drives the lifting frame 6 to rise. The support frame 3 has sliding grooves on the left and right sides that are adapted to the side walls of the lifting frame 6. The bottom wall of the sliding groove is provided with a normally open switch 18 for controlling the output of the atomizing nozzle 8. The sliding groove ensures the stability of the movement of the lifting frame 6. When the free end of the lifting frame 6 does not contact the normally open switch 18, all the atomizing nozzles 8 are closed to prevent the material from being sprayed out of the groove.

[0037] When cleaning the roller, not only does the liquid supply component need to be stopped, but the scraper body 17 also needs to be prevented from contacting the roller body 2. To this end, a gear 19 is provided on one side of the hinge plate 16, extending through the side wall of the support frame 3. The support frame 3 is also equipped with an angle adjustment component for controlling the fit between the scraper body 17 and the corresponding groove. The angle adjustment component includes a second cylinder 20, a rack 21, and a time delay switch 22. The support frame 3 is equipped with a time delay switch 22 connected to the normally open switch 18. The outer side of the support frame 3 is provided with… The second cylinder 20 is provided, and the output end of the second cylinder 20 is provided with a rack 21 that meshes with the gear 19. The delay switch 22 is connected to the second cylinder 20. When the atomizing nozzle 8 stops outputting, that is, the normally open switch 18 is opened and the delay switch 22 is activated. After the time required for the drum body 2 to rotate to the corresponding angle, the second cylinder 20 drives the rack 21 to move downward. The gear 19 on the hinge plate 16 drives the hinge plate 16 to tilt downward. After the scraper body 17 has cleaned the corresponding drying material, it no longer contacts the drum body 2.

[0038] In this embodiment, the scraper body 17 and the hinge plate 16 are detachably connected. The hinge plate 16 is T-shaped, and the main support plate 13 is provided with a positioning groove that fits the end of the hinge plate 16 away from the scraper body 17. One end of the scraper body 17 is an isosceles trapezoid, and a screw 23 is provided below the scraper body 17. The screw 23 passes through the hinge plate 16 and is connected to the nut 24. When a part of the scraper body 17 is damaged and the scraping is not clean, the corresponding atomizing nozzle 8 can be locked by the controller and will no longer output material. Other atomizing nozzles 8 continue to work until the material is dried. Then, the corresponding nut 24 is unlocked, and the scraper body 17 with the screw 23 is removed.

[0039] In this embodiment, a guide rod 25 is also provided below the scraper body 17, and a guide hole adapted to the guide rod 25 is provided on the hinge plate 16 to ensure the stable installation of the scraper body 17.

[0040] In this embodiment, both the main receiving plate 13 and the auxiliary receiving plate 14 are arranged at an angle to facilitate material collection.

[0041] If gear 19 and rack 21 are exposed to the outside world, they are easily affected by the external environment. Therefore, the support frame 3 is also provided with a protective cover 26 to protect rack 21 and gear 19, so as to ensure the overall stability of equipment operation.
