[0024] 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.

[0025] like Figures 1-4 As shown in the embodiment of this utility model: a granulator includes a shell 110, a granulating roller 120 installed inside the shell 110, and the granulating roller 120 is provided with four layers, each layer being provided with two sets. A feed inlet 130 is installed on the top of the shell 110, and a support plate 210 connected to the inner wall of the shell 110 is provided below each layer of granulating roller 120. Two sets of material discharge grooves 220 are opened inside the support plate 210, and two sets of support seats 230 are symmetrically arranged on the top of the support plate 210 with MM as the axis. A cavity 240 is symmetrically opened in the two sets of support seats 230, and a scraper 270 is connected to each cavity 240 through an elastic mechanism. The scraper 270 is attached to the outer wall of the granulating roller 120.

[0026] The elastic mechanism includes a spring 250 connected to the inner wall of the chamber 240, and the other end of the spring 250 is connected to a connecting plate 260 installed below the scraper 270.

[0027] In actual operation, when the granulation roller 120 is rotating, the scraper 270 abuts against the outer wall of the granulation roller 120, and the spring 250 is compressed and deformed. As the granulation roller 120 rotates, when the scraper 270 is in contact with the granulation groove, the elastic action of the spring 250 can push the scraper 270 to fit against the inner wall of the granulation groove, thus completing the scraping of the groove.

[0028] The end of the scraper 270 that is attached to the outer wall of the granulation roller 120 is made into a sharp shape.

[0029] The above design avoids obstructing the rotation of the granulation roller 120 by the scraper 270, while ensuring the scraping effect of the scraper 270 on the granulation roller 120.

[0030] The upper part of the material discharge trough 220 is set to be an arc shape that matches the outer wall of the granulation roller 120.

[0031] Through the above design, the sludge thickness of the outer wall of the granulating roller 120 can be limited, and the sludge thickness of the outer wall of the granulating roller 120 is prevented from being too thick.

[0032] The shapes of the two groups of material leakage grooves 220 on opposite sides are symmetrically inclined about M-M, and the lower end portions of the two groups of support seats 230 are aligned with the material leakage grooves 220.

[0033] Through the above design, the made sludge particles can be guided, and the discharging direction is ensured.

[0034] The chute 280 is arranged in the chamber 240, and the sliding block 290 is slidably connected in the chute 280, and the end of the sliding block 290 away from the chute 280 is connected to the connecting plate 260.

[0035] Through the above design, the stability of the track of the connecting plate 260 and the scraper 270 is ensured when they are telescoped in the chamber 240.

[0036] The width of the connecting plate 260 is greater than the width of the scraper 270.

[0037] Through the above design, the moving range of the scraper 270 is limited, and the scraper 270 is prevented from being separated from the inside of the chamber 240.

[0038] The material collecting groove 291 is arranged in the support seat 230, and the inner walls on the left and right sides of the material collecting groove 291 are inclined downward from top to bottom.

[0039] Through the above design, the scraped sludge can be collected, and it is prevented from falling into the machine.

[0040] As can be seen from the above, the working principle of the utility model is: when the granulating roller 120 rotates, the scraper 270 abuts against the outer wall of the granulating roller 120 at this time, and the spring 250 is extruded to deform, and with the rotation of the granulating roller 120, when the scraper 270 is attached to the granulating groove, at this time, the scraper 270 is pushed to attach to the inner wall of the granulating groove through the elastic action of the spring 250, and the scraping of the groove is completed.

[0041] It is apparent for those skilled in the art that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the utility model is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model. Any reference signs in the claims should not be regarded as limiting the involved claims.
