[0028] In the present utility model, if Figure 1-3 As shown, a scraper dryer that is easy to clean is provided, comprising a rotatable drum 1, a scraper 2 arranged on one side of the drum 1, and a collecting trough 3 arranged on the lower side of the scraper 2. A water trough 4 is provided on the lower side of the drum 1, and a drainage pipe 5 is provided on a section of the bottom wall of the water trough 4 away from the scraper 2. The drainage pipe 5 is located on the side of the center line of the drum 1 away from the scraper 2. The bottom wall of the water trough 4 extends obliquely downward from the lower side of the scraper 2 toward the drainage pipe 5 to form an inclined wall 6, and the inclined wall 6 extends away from the edge of the scraper 2 to the position of the drainage pipe 5; the side wall of the collecting trough 3 close to the drainage pipe 5 is provided with an openable and closable slag cleaning window.

[0029] When the scraper dryer of the utility model is in use, as shown in the figure, the bottom wall of the water tank 4 is provided with an inclined wall 6, so that the sediment in the water tank 4 is easy to move toward the drain pipe 5, especially under the promotion of the rotation of the drum 1, the sediment in the water tank 4 is more likely to move toward the drain pipe 5. Figure 3 As shown, there is a larger operating space between the bottom wall of the water tank 4 where the drain pipe 5 is located and the drum 1, so that the slag cleaning window can have a larger setting space, and it is convenient to operate in the water tank 4 during the slag cleaning operation.

[0030] In a preferred embodiment, a further optimized configuration of the structure of the utility model is that at least two slag cleaning windows are provided at intervals on the side wall of the collecting trough 3 along the axial direction of the drum 1 .

[0031] In a preferred embodiment, the structure of the utility model is further optimized in that a window hole 7 is provided on the side wall of the water tank 4 at the position of the slag cleaning window, and the edge of the window hole 7 protrudes outward to form a mounting platform; the slag cleaning window includes a window panel 8 and an insert block 9 connected to the window panel 8, and the insert block 9 can be inserted into the inner side of the mounting platform through interference, and the window panel 8 is limitedly abutted against the outer edge of the mounting platform.

[0032] like Figure 1 and 3 As shown, by providing an outwardly protruding mounting platform, the contact area between the interference-fitting portion of the insert block 9 and the water tank 4 can be increased to prevent the insert block 9 from falling out, while achieving sealing at the window hole 7 to prevent water from seeping out.

[0033] In a preferred embodiment, for the structure of the utility model, more specifically, the plug block 9 is configured as a rubber plug block 9 .

[0034] In a preferred embodiment, a further optimized configuration of the structure of the present invention is that a handle 10 is provided on the outer surface of the window panel 8 .

[0035] In a preferred embodiment, the structure of the utility model is further optimized in that a connecting wall 11 is provided at the lower edge of the side wall of the water tank 4 away from the scraper 2, and the connecting wall 11 extends obliquely downward toward the direction of the drain pipe 5. Figure 3 As shown, by providing the connecting wall 11, it is possible to avoid the water tank 4 from having four corners at the bottom of the side wall away from the scraper 2, so as to further facilitate the cleaning of the water tank 4.

[0036] In a preferred embodiment, for the structure of the utility model, a further optimized setting is that the inclined wall 6 includes: a first inclined wall section 601, which is arranged at a section of the inclined wall 6 toward the scraper 2; a second inclined wall section 602, which is arranged at a section of the first inclined wall section 601 toward the drain pipe 5; wherein the inclination angle of the first inclined wall section 601 is greater than the inclination angle of the second inclined wall section 602, and the scraper dryer also includes a slag cleaning piece, which is arranged on the upper side of the first inclined wall section 601, and the slag cleaning piece has a liquid outlet 12 facing the first inclined wall section 601, and the slag cleaning piece has a slag cleaning pipe 13 connecting the liquid outlet 12 and the outside.

[0037] As shown in the figure, by dividing the inclined wall 6 into the first inclined wall section 601 and the second inclined wall section 602, when liquid is introduced into the water tank 4 through the slag cleaning piece, the liquid flowing out of the liquid outlet 12 promotes the flow of sediment and liquid at the position of the first inclined wall section 601, so as to promote the sediment to flow toward the drain pipe 5. At the same time, when the sediment and liquid flowing along the bottom of the first inclined wall section 601 flow to the position of the second inclined wall section 602, the angle of the second inclined wall section 602 changes, causing the sediment and liquid to fluctuate, so as to promote part of the sediment to float up and contact the drum 1, and further promote the efficiency of the drum 1 adhering to the sediment for drying.

[0038] In a preferred embodiment, for the structure of the utility model, more specifically, the slag cleaning member includes a slag cleaning pipe 13, the slag cleaning pipe 13 extends along the axis direction of the drum 1, and the slag cleaning pipe 13 is provided with a plurality of liquid outlet holes 12 at intervals along the extension direction thereof. Figure 2 As shown, one end of the slag cleaning pipe 13 extends out of the outside of the water tank 4, and a slag cleaning pipe 13 is formed inside the slag cleaning pipe 13.

[0039] In a preferred embodiment, for the structure of the utility model, a further optimized setting is that the scraper dryer also includes an upper liquid pipe 14, the upper liquid pipe 14 is arranged on the side of the drum 1 away from the scraper 2, and the upper liquid pipe 14 is located on the upper side of the water tank 4, the upper liquid pipe 14 extends along the axial direction of the drum 1, and the upper liquid pipe 14 is provided with an upper liquid hole 15 facing the drum 1.

[0040] like Figure 2 and 3 As shown, by providing the upper liquid pipe 14, the upper liquid pipe 14 can be used to spray liquid onto the drum 1, so that the drum 1 can be dried by spraying the liquid, and the liquid dropped by the spraying can also replenish the liquid content in the water tank 4. Moreover, the dropped liquid forms an impact wave on the liquid in the water tank 4 at the position of the drain pipe 5, so as to further reduce the sedimentation and consolidation, and further reduce the difficulty of cleaning the water tank 4.

[0041] In a preferred embodiment, the structure of the utility model is further optimized in that an observation hole 16 is provided on the side wall of the water tank 4 in a direction perpendicular to the axis of the drum 1 at a section close to the scraper 2, and the scraper dryer also includes a hole cover 17 that can be opened and closed on the observation hole.

[0042] As shown in the figure, by setting up the observation hole 16, it is convenient to observe the state of the inclined wall 6 close to the scraper 2 when cleaning the water tank 4. In some embodiments, the observation hole 16 can also be used to directly flush and clean the inclined wall 6 through the water gun nozzle.

[0043] Regarding the fixing method of the hole cover 17, it is preferred to use a structure such as a slag cleaning window, or the hole cover 17 is fixed to the observation hole 16 using a threaded structure.

[0044] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
