DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] A furnace tube slag cleaning device, such as Figure 1 and Figure 2 As shown, it includes a mounting frame 1, a hydraulic cylinder 2, a handle 3, a mounting roller 4, a rotating disk 5, a brush 6 and a rotating mechanism 7. The top of the mounting frame 1 is connected to the hydraulic cylinder 2, the upper sides of the front and rear parts of the mounting frame 1 are both connected to the handle 3, the telescopic end of the hydraulic cylinder 2 is connected to the mounting roller 4, the right part of the mounting roller 4 is rotatably connected to the rotating disk 5, the rotating disk 5 is connected to the brush 6, and the rotating mechanism 7 is provided on the front side of the right part of the mounting roller 4.

[0019] like Figure 1 and Figure 3 As shown, the rotating mechanism 7 includes a mounting block 71, a motor 72, a gear 73 and a ring gear 74. The mounting block 71 is connected to the front right side of the mounting roller 4, the motor 72 is connected to the left side of the mounting block 71, the gear 73 is connected to the output shaft of the motor 72, the ring gear 74 is connected to the inner side of the rotating disk 5, and the gear 73 is meshed with the ring gear 74.

[0020] like Figure 1 and Figure 4 As shown, a scraping mechanism 8 is also included, and the scraping mechanism 8 includes a rotating shaft 81, a torsion spring 82 and a scraping piece 83. A plurality of rotating shafts 81 are connected to the right part of the installation roller 4, and the torsion spring 82 is connected between the rotating shafts 81 and the installation roller 4. The scraping pieces 83 are connected to the rotating shafts 81, and the scraping pieces 83 are in contact with each other. The scraping pieces 83 can only rotate in a clockwise direction. When the scraping pieces 83 rotate counterclockwise, they clamp each other to form a seal.

[0021] When the utility model is in use, the hydraulic cylinder 2 is first aligned with the furnace pipe opening through the handle 3, and then the hydraulic cylinder 2 is started. The hydraulic lever is extended and retracted to control the installation roller 4 to penetrate into the furnace pipe. When the installation roller 4 penetrates, the scraper 83 is squeezed by the residue on the inner wall of the furnace pipe, which drives the rotating shaft 81 to rotate clockwise. The scraper 83 rotates and unfolds clockwise, which makes it convenient for the installation roller 4 to enter the deep part of the furnace pipe and will not push the residue in the furnace pipe to the deep part. During the penetration process of the installation roller 4, the motor 72 is started, and the output shaft of the motor 72 rotates to drive the gear 73 The gear 73 rotates and drives the rotating disk 5 to rotate through meshing with the gear ring 74. The rotating disk 5 drives the brush 6 to rotate. The brush 6 rotates to clean the residue in the furnace tube. Then, the hydraulic cylinder 2 controls the mounting roller 4 to move out of the furnace tube. When moving out, the scraper 83 can scrape the residue in the furnace tube. When the scraper 83 scrapes the residue outward, the residue squeezes the scraper 83, so that the scraper 83 rotates counterclockwise. The scrapers 83 rotate counterclockwise and clamp each other to form a seal, thereby taking out the residue.
