Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, specifically relating to a dryer with an inner wall cleaning function. Background Technology

[0002] Rotary flash dryers are a common material processing equipment in industrial fields. The principle is relatively simple. During use, hot air enters the mixing and pulverizing drying chamber from the bottom of the dryer through the inlet pipe at a suitable jet speed. This causes strong shearing, collision, and friction on the material, which is then atomized. Due to the rotational flow of the gas and solid phases, the solid phase has greater inertia than the gas phase, resulting in a higher relative velocity between the two phases, which enhances mass and heat transfer between them.

[0003] A search revealed Chinese patent CN222306764U, which discloses a rotary flash dryer with an inner wall cleaning function. The dryer includes a main structure tower, with a discharge port on one side of the upper part of the tower. A plate valve is located at the upper end of the tower and above the discharge port. However, the prior art uses water flow to scour the inner wall, but due to the intervals between the rotating bundles of water, it is difficult to fully cover the inner wall, resulting in incomplete cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a dryer with an inner wall cleaning function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dryer with an inner wall cleaning function, comprising a dryer body, a sealing shell fixedly connected to the top of the dryer body by bolts, a reduction motor mounted on the top surface of the sealing shell, a first gear rotatably connected to the top surface of the sealing shell by a bearing, a second gear meshing with the surface of the first gear, the second gear rotatably connected to the sealing shell by a bearing, a limiting shell slidably connected inside the second gear, the limiting shell penetrating the surface of the sealing shell and rotatably connected to the sealing shell, a limiting plate provided inside the sealing shell, two fixing frames symmetrically fixedly connected to the bottom surface of the limiting plate, a support rod rotatably connected inside each fixing frame, and a cleaning brush fixedly connected to the side of the support rod facing the inner wall of the dryer body by bolts.

[0006] Preferably, two servo motor bodies are symmetrically mounted on the top surface of the limiting plate, and a second bevel gear is fixedly connected to the opposite side of the two support rods. The surface of the second bevel gear is meshed with a first bevel gear. The output shaft of the servo motor body passes through the surface of the limiting plate and is fixedly connected to the first bevel gear through a coupling.

[0007] Preferably, an electric push rod is installed on the top surface of the sealing shell, a linkage rod is slidably connected inside the limiting shell, the output shaft of the electric push rod is rotatably connected to the linkage rod, and the end of the linkage rod away from the electric push rod is fixedly connected to the limiting plate.

[0008] Preferably, a plurality of guide rods are slidably connected to the bottom surface of the sealing shell, and an annular rail is fixedly connected to the top surface of the limiting plate. The bottom end of each guide rod is inserted into the annular rail and slidably connected to the annular rail by a slider.

[0009] Preferably, the bottom surface of the limiting plate is fixedly connected to two sealing plates by bolts, and the adjacent sides of the two sealing plates are rotatably connected to a movable plate by a hinge.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a gear transmission system driven by a reduction motor to rotate the cleaning brush, and combines a folding and unfolding mechanism controlled by a servo motor to ensure that the cleaning brush fits tightly against the inner wall of the dryer. The bidirectional 120-degree reciprocating rotation design avoids the problem of power cord tangling, while ensuring no dead angles in cleaning. With the vertical movement function driven by the electric push rod, the cleaning brush can cover a larger inner wall area, significantly improving cleaning efficiency and comprehensiveness, and preventing residue accumulation from affecting the drying effect.

[0014] 2. This utility model adopts an elastic rope linkage sealing plate structure, which automatically forms a sealing isolation layer when the cleaning brush is unfolded. The staggered sealing sheet and elastic pad design can completely seal the drying chamber after the cleaning brush is retracted, effectively isolating the drive components from the corrosion of high temperature, moisture or materials. This design not only ensures the normal operation of the cleaning function, but also greatly extends the service life of the core components and reduces maintenance costs.

[0015] 3. This utility model is equipped with various drive units, all of which adopt high-precision coding control and programmable adjustment of rotation angle, travel distance and speed parameters. This modular design allows the equipment to adapt to the cleaning needs of dryers of different specifications. Customized cleaning solutions can be achieved by adjusting the operating parameters, while ensuring precise and reliable operation and avoiding mechanical interference or excessive wear.

[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. 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.

[0022] Please see Figures 1-4This utility model provides a dryer with an inner wall cleaning function, including a dryer body 1. A sealing shell 2 is fixedly connected to the top of the dryer body 1 by bolts. A reduction motor 3 is installed on the top surface of the sealing shell 2. A first gear 4 is rotatably connected to the top surface of the sealing shell 2 via a bearing. A second gear 5 is meshed with the surface of the first gear 4. The second gear 5 is rotatably connected to the sealing shell 2 via a bearing. A limit shell 6 is slidably connected inside the second gear 5. The limit shell 6 penetrates the surface of the sealing shell 2 and is rotatably connected to the sealing shell 2. A limit plate 7 is provided inside the sealing shell 2. Two fixing frames 8 are symmetrically fixedly connected to the bottom surface of the limit plate 7. A support rod 9 is rotatably connected inside each fixing frame 8. A cleaning brush 10 is fixedly connected to the side of the support rod 9 facing the inner wall of the dryer body 1 by bolts. Two servo motor bodies 11 are symmetrically installed on the top surface of the limit plate 7. A second bevel gear 13 is fixedly connected to the opposite side of the two support rods 9. A first bevel gear 12 is meshed with the surface of the second bevel gear 13. The output shaft of the servo motor body 11 penetrates the limit plate 7. The surface of the plate 7 is fixedly connected to the first bevel gear 12 via a coupling. When it is necessary to clean the inner wall of the dryer body 1, the servo motor body 11 is first connected to an external power source and started. The first bevel gear 12 will drive the support rod 9 to rotate inside the fixed frame 8 through the second bevel gear 13 until the cleaning brush 10 is in contact with the inner wall of the dryer body 1, thus folding the cleaning brush 10. The surface cleaning brush 10 is inside the dryer body 1, thus affecting the drying effect inside the dryer body 1. Then, the reduction motor 3 is connected to an external power source and started. The first gear 4 will drive the limiting shell 6 to rotate inside the sealing shell 2 through the second gear 5, thereby indirectly driving the two cleaning brushes 10 to rotate inside the dryer body 1 through the limiting plate 7. After the reduction motor 3 rotates 120 degrees, it will rotate in the opposite direction again, avoiding the power cord from being tangled when the servo motor body 11 rotates. This allows the cleaning brush 10 to rub against the inner wall surface of the dryer body 1, thereby achieving a comprehensive cleaning of the inner wall of the dryer body 1 and avoiding any omissions.

[0023] It should be noted that the geared motor 3 used in this application is composed of a servo motor with an encoder and a gearbox, which can reduce the output speed and increase the torque. The number of rotations and rotation angle of the motor output shaft are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0024] It should be noted that the servo motor body 11 used in this application has a controllable number of rotations and rotation angle of the motor output shaft with high precision. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0025] In this embodiment, an electric push rod 14 is installed on the top surface of the sealing shell 2, and a linkage rod 15 is slidably connected inside the limiting shell 6. The output shaft of the electric push rod 14 is rotatably connected to the linkage rod 15. The end of the linkage rod 15 away from the electric push rod 14 is fixedly connected to the limiting plate 7. Several guide rods 16 are evenly slidably connected to the bottom surface of the sealing shell 2, and an annular rail 17 is fixedly connected to the top surface of the limiting plate 7. The bottom end of each guide rod 16 is inserted into the annular rail 17 and is slidably connected to the annular rail 17 through a slider. When the cleaning brush 10 cleans the inner wall of the dryer body 1, the electric push rod 14 is connected to an external power source and then started. The linkage rod 15 will rotate inside the limiting shell 6, so that the limiting plate 7 will drive the cleaning brush 10 to move downward inside the dryer body 1, which can make the cleaning brush 10 have a downward extension effect, thereby increasing the cleaning range of the cleaning brush 10.

[0026] It should be noted that the electric push rod 14 used in the application is used in conjunction with a magnetic switch, proximity switch or photoelectric switch to achieve precise control of the push rod's extension and retraction displacement. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0027] In this embodiment, two sealing plates 18 are fixedly connected to the bottom surface of the limiting plate 7 by bolts. A movable plate 19 is rotatably connected to the adjacent side of the two sealing plates 18 via a hinge. A sealing gasket is fixedly connected to the bottom surface of each movable plate 19 near the sealing plate 18. An elastic rope 21 is fixedly connected to the top surface of each sealing plate 18. The side of the elastic rope 21 away from the sealing plate 18 is fixedly connected to the movable plate 19. A sealing sheet 20 is fixedly connected to the adjacent side of the two movable plates 19. The two sealing sheets 20 are staggered and overlapped vertically. When the two cleaning brushes 10 rotate downwards, the two movable plates 19 will be pressed by the cleaning brushes 10 and hinged to seal the sealing plate 19. When the surface of plate 18 rotates, the elastic rope 21 connected to it is stretched. As the two movable plates 19 rotate, the two sealing pads are squeezed and deformed until the two cleaning brushes 10 are in contact with the inner wall of the dryer body 1. The sealing plate 18 rotates with the rotation of the limiting plate 7. When the two cleaning brushes 10 are folded up, the two movable plates 19 will rotate due to the elastic potential energy of the elastic rope 21 until the two movable plates 19 are on the same axis. The two sealing plates 20 overlap and interlock, thus isolating the cleaning brushes 10 from the dryer body 1 and preventing damage to the components driving the cleaning brushes 10 when drying inside the dryer body 1.

[0028] The use of this utility model involves the following steps:

[0029] S1: When it is necessary to clean the inner wall of the dryer body 1, firstly connect the servo motor body 11 to the external power supply and start it. The first bevel gear 12 will drive the support rod 9 to rotate inside the fixed frame 8 through the second bevel gear 13 until the cleaning brush 10 is in contact with the inner wall of the dryer body 1, thus folding the cleaning brush 10. The surface cleaning brush 10 is inside the dryer body 1, thereby affecting the drying effect inside the dryer body 1. Then connect the reduction motor 3 to the external power supply and start it. The first gear 4 will drive the limiting shell 6 to rotate inside the sealing shell 2 through the second gear 5, thereby indirectly driving the two cleaning brushes 10 to rotate inside the dryer body 1 through the limiting plate 7. After the reduction motor 3 rotates 120 degrees, it will rotate in the opposite direction again, which avoids the power cord of the servo motor body 11 from being tangled when rotating, so that the cleaning brush 10 can rub against the inner wall surface of the dryer body 1, thereby achieving a comprehensive cleaning of the inner wall of the dryer body 1 and avoiding omissions.

[0030] S2: When the cleaning brush 10 cleans the inner wall of the dryer body 1, the electric push rod 14 is connected to the external power supply and then started. The linkage rod 15 will rotate inside the limiting shell 6, so that the limiting plate 7 will drive the cleaning brush 10 to move downward inside the dryer body 1, which can make the cleaning brush 10 have the effect of extending downward, thereby increasing the cleaning range of the cleaning brush 10.

[0031] S3: When the two cleaning brushes 10 rotate downwards, the two movable plates 19 will rotate on the surface of the sealing plate 18 through hinges due to the pressure of the cleaning brushes 10. The elastic rope 21 connected to it will be stretched. At the same time as the two movable plates 19 rotate, the two sealing pads will be squeezed and deformed until the two cleaning brushes 10 are in contact with the inner wall of the dryer body 1. The sealing plate 18 will rotate with the rotation of the limiting plate 7. When the two cleaning brushes 10 are folded up, the two movable plates 19 will rotate due to the elastic potential energy of the elastic rope 21 until the two movable plates 19 are on the same axis. The two sealing plates 20 overlap and interlock, which realizes the isolation between the cleaning brushes 10 and the dryer body 1, and avoids damage to the components driving the cleaning brushes 10 when drying inside the dryer body 1.

[0032] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
