[0002] A drum scraper dryer is a device that conducts internal heating and rotation to continuously dry liquid materials or slurries attached to the outer wall of the drum. When the drum scraper dryer is working, the rotating drum adheres to a thick film of material through the lower trough. Heat is transported through a pipeline to the inner wall of the drum, then conducted to the outer wall of the drum, and further conducted to the material film, causing the water in the material film to evaporate and dehumidify, and the material to be dried. The dried material is scraped off the drum by a scraper on the drum surface, falls into the discharge port, and is concentrated and packaged.

[0020] Referring to Figures 1 - 3 , a drum scraper dryer, including a drum scraper dryer body 1, a fixed seat 2 is arranged on one side of the drum scraper dryer body 1, a material guiding plate assembly 3 is arranged on the top of the fixed seat 2, and the material guiding plate assembly 3 and the fixed seat 2 are connected and fixed by a plurality of fastening assemblies 5. The material guiding plate assembly 3 includes a horizontal material guiding plate and an inclined material guiding plate. An inclined material guiding plate is arranged on one side of the horizontal material guiding plate, and limiting plates are installed on both sides of the horizontal material guiding plate and the inclined material guiding plate. It should be noted that the drum scraper dryer body 1 includes a drum, and the specific structure and working mode of the drum scraper dryer body 1 are all prior arts that have been publicly available on the market at present, and do not belong to the main technical problems to be solved in this technical solution. Therefore, it will not be elaborated in detail in the present invention. The fastening assembly 5 is a fastening screw and a fastening nut, and the fastening screw is in threaded connection with the fastening nut.
[0021] Moreover, a first scraper assembly 4-1 and a second scraper assembly 4-2 are arranged at equal intervals in sequence between the two limiting plates of the horizontal material guiding plate. Limiting sliding blocks 42 are symmetrically arranged on both sides of the first scraper assembly 4-1 and the second scraper assembly 4-2. The limiting sliding blocks 42 are slidably arranged in the limiting plates, and a fixing screw is arranged on the other side of the limiting sliding blocks 42. One side of the fixing screw passes through the limiting plate and is screwed with a fixing nut.
[0022] At the same time, a limiting sliding groove is opened in the limiting plate of the horizontal material guiding plate at the position of the limiting sliding block 42, and a groove is opened on one side of the end of the limiting plate at the limiting sliding groove. A magnetic attraction plate 33 is fixedly arranged in the groove, and a through sliding groove is opened in the limiting plate at the position of the fixing screw.
[0023] Moreover, a feeding through hole is arranged on the side of the limiting plate of the horizontal material guiding plate close to the inclined material guiding plate. The feeding through hole is on one side of the limiting sliding groove, and the cross-sectional area of the feeding through hole is the same as the cross-sectional area of the limiting sliding block 42.
[0024] At the same time, a sliding groove through hole is arranged on the side of the limiting plate of the horizontal material guiding plate at the feeding through hole, and the width of the sliding groove through hole is the same as the diameter of the fixing screw.
[0025] Further, both the first scraper assembly 4-1 and the second scraper assembly 4-2 include a fixed scraper body 41. Both sides of the scraper body 41 are made of a magnetic material adapted to be attracted to the magnetic plate 33, and one end of the scraper body 41 is provided with an extension plate 43. The top of the extension plate 43 is flush with the top of the scraper body 41. The extension plate 43 is used to further guide the materials scraped off the top of the scraper body 41. It should be noted that both the scraper body 41 and the extension plate 43 are inclined, so that when the scraper body 41 is scraping materials, the scraped materials are guided along the scraper body 41 and the extension plate 43 to the guide plate assembly 3.
[0026] Further, a first limit plug 31 and a second limit plug 32 are sequentially arranged at the bottoms of the horizontal guide plate and the inclined guide plate, and clamping grooves are provided at the top of the fixed seat 2 at the positions of the first limit plug 31 and the second limit plug 32.

When it is necessary to disassemble the first scraper assembly 4-1 and the second scraper assembly 4-2, slide the first scraper assembly 4-1 and the second scraper assembly 4-2 in the limit chute to the side of the feeding through hole and locate them in the feeding through hole. The fixing screw slides in the corresponding through chute and slides to be located in the chute through hole. Then, take out the first scraper assembly 4-1 and the second scraper assembly 4-2 along the feeding through hole to clean the first scraper assembly 4-1 and the second scraper assembly 4-2.
[0030] After the cleaning is completed, slide the first scraper assembly 4-1 and the second scraper assembly 4-2 inward along the feeding through hole, align the first scraper assembly 4-1 and the second scraper assembly 4-2 with their corresponding limit sliding grooves in sequence, and then slide along the corresponding limit sliding grooves until they reach the appropriate positions, and then tighten and fix them with fixing screws and fixing nuts, so as to complete the limitation of the first scraper assembly 4-1 and the second scraper assembly 4-2. Both sides of the first scraper assembly 4-1 and the second scraper assembly 4-2 are magnetically adsorbed and connected to the corresponding magnetic adsorption plates 33, further ensuring the stability of the first scraper assembly 4-1 and the second scraper assembly 4-2.
[0031] In the present utility model, through the cooperative setting of the material guiding plate 3 and the first scraper assembly 4-1 and the second scraper assembly 4-2, it is convenient to finely adjust the distance between the scraper and the drum of the drum scraper dryer body 1.
