In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in fig. 1-4, the present application provides a drum dryer, which comprises a housing 1, a drum 2 located inside the housing 1, a driving device 3 located on the housing 1, a film control device 4 located on one side of the drum 2, and a scraping device 5 located on the other side of the drum 2.

The bottom in the shell 1 is formed with middle sunken silo 11, and one side of 1 outer wall of shell is provided with discharge gate 12, and the opposite side outer wall then is fixed with axle sleeve 13, and axle sleeve 13 communicates to inside the shell 1, and 1 upside of shell is provided with feed inlet 14, is located 1 inner wall of shell of 13 both sides of axle sleeve and is fixed with at least one guiding axle 15, and in this actual implementation, guiding axle 15 is provided with two, and axle sleeve 13 upside is provided with opening 16.

The driving device 3 includes supporting blocks 31 fixed at the lower sides of the two ends of the housing 1, roller sleeves 32 are fixed on the upper sides of the supporting blocks 31, the rotating shafts at the two ends of the roller 2 penetrate through the housing 1 and are rotatably connected in the roller sleeves 32, and a driver 33 is fixed on the roller sleeve 32 at one side.

The scraping device 5 comprises a supporting plate 51 and a material guide plate 52 which are positioned on one side of the roller 2 close to the discharge port 12, two ends of the supporting plate 51 are fixed on the inner wall of the shell 1, a scraper 53 is fixed on one side of the supporting plate 51 close to the roller 2, the scraper 53 is attached to the surface of the roller 2, two ends of the material guide plate 52 are fixed on the inner wall of the shell 1, one side of the material guide plate 52 is positioned below the scraper 53, and the other side of the material guide plate inclines downwards and extends into the discharge port 12.

The film control device 4 comprises a scraper 41 positioned on one side of the roller 2 far away from the discharge hole 12, a slide block 42 positioned on one side of the shaft sleeve 13 close to the roller 2, a threaded sleeve 43 rotatably connected to the other side of the shaft sleeve 13, and a pointer 44 fixed on the outer wall of the shell 1.

The middle of the two ends of the scraper 41 is fixed with one end of a rotating rod 411, the other end of the rotating rod 411 is rotatably connected with the inner wall of the housing 1, one side of the scraper 41 close to the drum 2 is formed with a knife face 412, the other side of the scraper 41 is hinged with one end of at least one linkage 413, and the other end of the linkage 413 is hinged with the sliding block 42.

The slide block 42 is provided with a guide hole 421 corresponding to the position of the guide shaft 15, the guide hole 421 is sleeved on the guide shaft 15, one side of the slide block 42 is fixed with a threaded shaft 422 corresponding to the position of the shaft sleeve 13, one end of the threaded shaft 422 penetrates through the shaft sleeve 13 and is in threaded connection with the threaded sleeve 43, a scale groove 423 is concavely formed on the upper side of the threaded shaft 422, and scales 424 are arranged in the scale groove 423.

A handle 431 is fixed on the outer wall of the threaded sleeve 43.

The pointer 44 is positioned on the upper side of the opening 16, and one end of the pointer 44 is inserted into the scale groove 423.

It is understood that a heating unit (not shown) is provided in the drum 2 to increase the temperature of the drum 2 for drying.

In the present embodiment, the supporting block 31 and the drum jacket 32 are used to support the drum 2. The user can pour the feed liquid into the shell 1 through the feed inlet 14, and the feed liquid is concentrated at the bottom of the roller 2 through the cambered surface of the trough 11. The driver 33 drives the roller 2 to rotate, the surface of the roller 2 is behind the feed liquid passing through the trough 11, the feed liquid can be attached to the roller 2 to form a layer of liquid film, and the liquid film can rotate along with the roller 2. The roller 2 is heated by the heating component, and the roller 2 can dry the liquid film to separate out the material from the liquid film.

When the liquid film rotates along with the roller 2, the liquid film passes through the film control device 4, and part of the liquid film is scraped through the knife face 412, so that the residual liquid film can be completely dried when reaching the scraping device 5, and the effect of controlling the thickness of the liquid film is achieved.

When the liquid film reachd scraper 5 position, because the liquid film has been dried for the material that adheres to on cylinder 2 surface this moment, scrape the material from cylinder 2 surface through scraper 53, the material is constantly piled up, will fall on stock guide 52 at last, makes the material pass through self gravity, and along stock guide 52 slip to discharge gate 12, discharge shell 1 is convenient for retrieve, reaches the stoving feed liquid to the effect of collecting the discharge material.

The user rotates the threaded sleeve 43 through the handle 431, and the threaded sleeve 43 drives the threaded shaft 422 and thus the sliding block 42 to move through the threaded connection between the threaded sleeve 43 and the threaded shaft 422 and the support of the threaded sleeve 43 by the sleeve 13. When the slider 42 moves, the linking rod 413 pushes one end of the scraper 41 far away from the knife surface 412, so that the scraper 41 rotates around one end of the linking rod 413, and the knife surface 412 is close to or far away from the roller 2.

When the threaded sleeve 43 extends into the shell 1, the cutter face 412 is driven to be far away from the roller 2, so that a thick liquid film is reserved on the surface of the roller 2, the condition that the feed liquid is dried quickly is adapted, the problem of excessive drying is avoided, and the drying speed is increased; when the threaded sleeve 43 extends out of the housing 1, the tool face 412 is driven to be close to the roller 2, so that a thin liquid film is reserved on the surface of the roller 2, the condition that the feed liquid is dried slowly is adapted, and the problem of insufficient drying is avoided.

The slider 42 can be stably moved and prevented from being deviated by the cooperation of the guide hole 421 and the guide shaft 15.

Because the screw thread bush 43 moves and can drive the knife face 412 to be close to or far away from the roller 2, namely the position of the screw thread bush 43 can reflect the distance between the knife face 412 and the roller 2 laterally, the pointer 44 is matched with the scale 424 to display the distance between the knife face 412 and the roller 2, when the screw thread bush 43 is rotated, a user can conveniently observe the distance between the knife face 412 and the roller 2 at the moment pointed out by the pointer 44 in the scale groove 423 directly through the opening 16, the user can adjust the distance, and the problem that the distance between the knife face 412 and the roller 2 is difficult to adjust is solved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
