[0026] For the wet granulator residue recycling device with the above structure, during use, first adjust the height of the second scraper 112 according to the depth of the granulating pot, then rotatably install the annular body 100 at the upper part of the granulating pot and make the lower end surface of the second scraper 112 abut against the inner bottom wall of the granulating pot, and then adjust the horizontal distance between the mounting rod 110 and the annular body 100 through the adjustment component 200 so that the side surface of the first scraper 111 abuts against the inner side wall of the granulating pot, and finally rotate the annular body 100 so that the first scraper 111 scrapes off the residue on the inner side wall of the granulating pot during rotation, and the second scraper 112 scrapes off the residue on the inner bottom wall of the granulating pot during rotation, thereby reducing the steps of manually scraping the residue, and using the synchronous rotation of multiple first scrapers 111 and second scrapers 112 is beneficial to achieving the effect of scraping the residue over a large area, and further facilitating the subsequent collection of the residue by people and accelerating the efficiency of residue recycling.

[0027] It can be understood that, in order to further increase the area of the surplus material scraped by the annular body 100 during a single rotation, the sum of the height dimensions of the first scraper 111 and the second scraper 112 is equal to or greater than the depth dimension of the granulation pot, and the length dimension of the second scraper 112 is equal to or less than the radial dimension of the granulation pot. In addition, according to the number of stirring blades and the positions of cutting blades of the existing granulation pot, fan-shaped scraping areas are defined between two adjacent stirring blades in the granulation pot, so as to determine the angle by which the annular body 100 can rotate, and make each first scraper 111 and second scraper 112 located in the corresponding fan-shaped scraping area, which is beneficial to the rotating annular body 100 to be able to scrape the surplus material in multiple fan-shaped scraping areas at the same time, thereby accelerating the efficiency of surplus material recovery.

[0028] See Figure 1 and Figure 2 , further, the annular body 100 is transversely provided with a mounting hole, the position adjusting assembly 200 includes a movable rod 201, one end of the movable rod 201 is movably inserted through the mounting hole, the upper end of the mounting rod 110 is connected to the other end of the movable rod 201, the movable rod 201 is threadedly connected with a first nut 202, and an elastic member 203 is provided between the first nut 202 and the outer wall of the annular body 100. The elastic member 203 is used to generate an elastic force that drives one end of the movable rod 201 to move outwards, so that the first scraper 111 can always abut against the inner side wall of the granulation pot, facilitating the subsequent scraping of the surplus material on the inner side wall by the first scraper 111. It can be understood that during use, the position of the first nut 202 is rotated so that the first nut 202 can move towards one side of the annular body 100, thereby increasing the elastic potential energy stored by the compression of the elastic member 203, and further increasing the elastic force of the elastic member 203 that drives one end of the movable rod 201 to move outwards. It can be understood that the mounting rod 110 can be fixed to the movable rod 201 by welding or threaded fitting, which will not be elaborated here.

[0030] See Figure 1 and Figure 2 , further, the first nut 202 is connected with a mounting plate, the elastic member 203 is a spring movably sleeved on the movable rod 201, one end of the spring abuts against the mounting plate, and the other end of the spring is connected to the annular body 100, so as to push the spring into a compressed state through the mounting plate, which is beneficial to standardize the deformation direction of the spring, and further enables the spring to store greater elastic potential energy.

[0032] See Figure 1 and Figure 2 Figure 2 , further, the first sleeve 113 is connected with a third scraper 114, the third scraper 114 is arranged at an angle with the first scraper 111, and the first scraper 111 and the third scraper 114 are inclined to abut against the inner wall of the granulating pot, so that it is convenient for the first scraper 111 and the third scraper 114 to scrape off the surplus materials on the inner wall of the granulating pot for multiple times during the repeated rotation of the annular body 100.

[0033] Further, the first scraper 111, the first sleeve 113 and the third scraper 114 are of an integral structure. Specifically, the first scraper 111, the first sleeve 113 and the third scraper 114 can be fixed together by welding, or can be integrally formed by integral injection molding, which will not be elaborated here.

It can be understood that the mounting rod 110 can be provided with external thread sections at the upper and lower parts, and the middle part of the mounting rod 110 is a smooth rod, so that it is convenient for the first sleeve 113 to be installed on the upper external thread section, and the second sleeve 115 to be installed on the lower external thread part.

[0035] See Figure 1 and Figure 2 Figure 2 , further, the annular body 100 is provided with a cross bar 101, the middle part of the cross bar 101 is connected with a vertical bar 102, and a groove is arranged at the lower end of the vertical bar 102 for cooperating with the rotating shaft of the stirring blade. During installation, the groove is sleeved on the rotating shaft of the stirring blade, so that the annular body 100 can rotate relative to the granulating pot. It can be understood that the outer diameter of the annular body 100 can be equal to or slightly smaller than the inner diameter of the granulating pot, so that it is convenient for the annular body 100 to be placed on the upper part of the granulating pot and also to rotate relative to the granulating pot.
