[0022] The automatic cleaning device for the spray dryer provided by the embodiments of the present application will be described in detail below in combination with specific embodiments. Figs. 1-2

[0023] Please refer to Figs. 1-2 , Fig. 1 is a structural schematic diagram of the automatic cleaning device for the spray dryer provided by one of the embodiments of the utility model; Fig. 2 is a side view of the automatic cleaning device for the spray dryer provided by one of the embodiments of the utility model. The automatic cleaning device 100 for the spray dryer provided by one of the embodiments of the utility model comprises brush heads 10 and a mounting frame 20. The brush heads 10 are provided with four; the mounting frame 20 is provided in a cross shape, the four brush heads 10 are respectively arranged at the four corners of the mounting frame 20, and the brush heads 10 can move on the mounting frame 20 to adapt to the drying machine pipes of different diameters, and then tightly adhere to the drying machine pipes of different diameters.

[0024] ​The mounting frame 20 is cross-shaped and the brush head 10 can move thereon to adapt to different diameters of the pipeline, ensuring that the brush head 10 can be closely fitted with the pipeline of different diameters of the dryer. Close fitting is one of the key factors to achieve good cleaning effect, because only when the brush head 10 is in full contact with the inner wall of the pipeline, during the movement of the brush head 10, can the dirt be scraped and brushed off by the cleaning components such as the bristles of the brush head 10 to the maximum extent, avoiding the occurrence of cleaning omissions due to poor fitting, so that the pipeline of different diameters can be cleaned effectively and specifically. In actual production scenarios, the pipeline diameter of the spray dryer often varies due to different equipment models, production process requirements and other factors. The device can be flexibly adapted to pipelines of various diameters through the movement adjustment of the brush head 10 on the mounting frame 20, greatly improving its versatility. Enterprises do not need to equip multiple specialized cleaning devices for dryer pipelines of different diameters, reducing equipment procurement and management costs, and one such automatic cleaning device 100 can meet the cleaning needs of various pipelines, facilitating switching between different specifications of spray dryer pipeline cleaning work.

[0025] Specifically, the operator first adjusts the positions of the four brush heads 10 on the mounting frame 20 according to the actual diameter of the spray dryer pipeline to be cleaned. Through the corresponding movement adjustment mechanism (such as setting a track on the mounting frame 20 for the brush head 10 to slide, and matching with screws, buckles and other fixing devices to facilitate fixing the brush head 10 after adjusting the position), the four brush heads 10 can be closely fitted with the inner wall of the pipeline of the diameter, ensuring that the cleaning components such as the bristles of the brush head 10 can fully contact the inner wall of the pipeline. Place the adjusted automatic cleaning device 100 at the inlet end of the dryer pipeline, and then rotate the mounting frame 20, which will drive the four brush heads 10 to rotate around the central axis of the pipeline. During rotation, the four brush heads 10 act like four small cleaning brush discs, with their bristles constantly scraping the inner wall of the pipeline to brush off the dirt, material residues and other impurities attached to the inner wall.

[0026] In some embodiments, strip-shaped holes 21 are formed on the mounting frame 20, and two strip-shaped holes 21 are cross-shaped, and the four brush heads 10 are movably arranged in the two strip-shaped holes 21.

[0027] The strip-shaped hole 21 provides the brush head 10 with a clear linear movement path, so that the brush head 10 can be accurately moved along the direction of the hole when adjusting the position, so that it can be more accurately fitted to the inner wall of the pipe of different diameters. In this way, it can ensure that the brush head 10 is in an ideal close-fitting state with the inner wall of the pipe, avoiding the situation that part of the brush head 10 has a large gap with the pipe wall due to inaccurate position adjustment, which affects the cleaning effect. For example, for small spray dryers with high pipe diameter accuracy requirements, through fine adjustment along the strip-shaped hole 21, it can be ensured that the four brush heads 10 can be properly fitted to the inner wall of the pipe, achieving efficient cleaning.

[0028] When it is necessary to use the automatic cleaning device 100 to clean the spray dryer pipe of a specific pipe diameter, the operator will first place the automatic cleaning device 100 on a workbench or a suitable space position for easy operation, and then manually hold the brush head 10 to move and adjust the position along the strip-shaped hole 21 according to the known pipe diameter size of the pipe to be cleaned. For example, if the pipe diameter is small, the brush head 10 is moved along the strip-shaped hole 21 to the center position of the mounting frame 20, so that the spacing between the four brush heads 10 is reduced; if the pipe diameter is large, the brush head 10 is moved away from the center of the mounting frame 20 along the strip-shaped hole 21 to increase the spacing between them, until the four brush heads 10 are roughly matched to the diameter of the pipe to be cleaned.

[0029] In some embodiments, the end of the brush head 10 is provided with a connecting rod 11, which is in sliding connection with the mounting frame 20. By providing the connecting rod 11, the connection between the brush head 10 and the mounting frame 20 can be more stable.

[0030] In some embodiments, the connecting rod 11 comprises a rod portion 111 and a head portion 112, the head portion 112 is connected with the rod portion 111, and the head portion 112 is accommodated in the strip-shaped hole 21. The head portion 112 is accommodated in the strip-shaped hole 21, so that the connection between the connecting rod 11 and the mounting frame 20 is more stable. The inner wall of the strip-shaped hole 21 can limit and support the head portion 112 from multiple directions. During the operation of the cleaning device, no matter whether the brush head 10 is subjected to friction force, impact force from the inner wall of the pipeline, or inertial force generated when the entire device moves, etc., through the stable “fitting” of the head portion 112 in the strip-shaped hole 21, these forces can be better transmitted and dispersed to the mounting frame 20, so that the connection between the connecting rod 11 and the mounting frame 20 will not easily appear loose, disconnection and other connection failures, thereby providing a reliable connection basis for the brush head 10 to stably participate in the cleaning work. When the brush head 10 performs a cleaning action, the force is transmitted along the connecting rod 11, and the arrangement of the head portion 112 in the strip-shaped hole 21 can make the force evenly dispersed on the contact surface of the strip-shaped hole 21, thereby avoiding stress concentration at a certain position of the connection point between the connecting rod 11 and the mounting frame 20. For example, when the brush head 10 scrapes stubborn dirt on the inner wall of the pipeline, a larger reaction force is generated, and through the reasonable force distribution of the head portion 112 in the strip-shaped hole 21, the entire connecting rod 11 and the mounting frame 20 can better withstand these forces, thereby reducing the risk of component damage caused by excessive local stress, prolonging the service life of each component of the device, and ensuring the long-term stable operation of the cleaning device.

[0031] In some embodiments, the brush head 10 is hollow inside to form a containing cavity, the containing cavity can contain cleaning liquid, and the head portion 112 of the brush head 10 is further provided with a spray head 12, the spray head 12 is in communication with the containing cavity. The hollow inside of the brush head 10 forms the containing cavity and is equipped with the spray head 12, so that the cleaning liquid can be directly sprayed on the dirt on the inner wall of the pipeline during the cleaning process. When the brush head 10 contacts the inner wall of the pipeline and performs a cleaning action such as rotation, axial movement, etc., the spray head 12 synchronously sprays the cleaning liquid, which can quickly soften and dissolve stubborn dirt and material residues, so that the bristles of the brush head 10 can more easily scrape them off, thereby significantly improving the cleaning efficiency and quality and reducing the cleaning dead angle. For example, for some material residues that have accumulated and dried on the inner wall of the pipeline of the dryer for a long time, it may be difficult to completely remove them by simply relying on the physical scraping of the bristles of the brush head 10, but after the cleaning liquid sprayed by the spray head 12 is used to pre-treat the dirt, the dirt can be easily removed.

[0032] In some embodiments, the device further comprises a driving device 30, the driving device 30 is connected with the mounting frame 20 to drive the mounting frame 20 to rotate and in turn drive the brush head 10 to rotate and clean the pipeline of the dryer.

[0033] The driving device 30 can provide stable and continuous rotating power for the mounting frame 20, ensuring that the mounting frame 20 can drive the brush head 10 to rotate in the drying machine pipeline at a uniform speed and smoothly. Compared with unstable methods such as manual rotation, the mechanical driving method does not have the problems of uneven rotation speed and pause in the middle, so that the bristles of the brush head 10 can always scrape the inner wall of the pipeline with a relatively uniform force and frequency, effectively cleaning more areas of the inner wall of the pipeline in unit time, greatly improving the cleaning efficiency, quickly completing the cleaning work of the entire drying machine pipeline, and the advantage is more obvious for longer and larger diameter pipelines, which can effectively save cleaning time and labor cost. The driving device 30 can be a commonly available driving motor on the market.
