Description

Technical Field

[0001] The utility model relates to the field of drying equipment, and more specifically, to a disk continuous dryer which is convenient for maintenance. Background Art

[0002] A disk continuous dryer is an efficient conduction-type continuous drying equipment. The main components of the disk continuous dryer include drying disks, a main shaft, rake arms, and rake blades. There are 2-8 rake arms fixed on the main shaft on each layer of drying disk, and the rake blades are connected to the rake arms. During the rotation of the rake arms, the rake blades will push the materials on the drying disks to the next drying disk, and the moisture inside the materials is dried by contacting with the drying disks.

[0003] In order to ensure that the rake blades can disperse and push the materials more effectively, the rake blades generally contact with the drying disks. Therefore, during the long-term contact between the rake blades and the drying disks, the scraping blades on the rake blades will be worn, so the scraping blades need to be replaced. However, the rake blades are arranged along the length direction of the rake arms. If the rake blades located near the main shaft are blocked by the outer rake blades, people need to remove all the outer rake blades first, then remove the rake blades located deep inside, and finally replace the scraping blades on the rake blades. Such a setting makes the maintenance of the rake blades inconvenient.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a disk continuous dryer which is convenient for maintenance.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a disk continuous dryer which is convenient for maintenance, including a main shaft and a plurality of drying disks. A plurality of rake arms are fixedly connected to the main shaft. An installation sleeve is sleeved on the rake arms. A plurality of rake blades are installed on the installation sleeve. The plurality of rake blades are linearly arranged in an array along the length direction of the installation sleeve. The lower end of the rake blade is connected with a scraping blade through a bolt. The installation sleeve can slide away from the main shaft and can drive all the rake blades out of the drying disks.

[0007] The utility model is further arranged as follows: a sliding groove is formed on the outer peripheral wall of the rake arm, and a sliding block located in the sliding groove is fixedly connected to the inner wall of the installation sleeve.

[0008] The utility model is further arranged as follows: the sliding groove includes a first sliding groove, a second sliding groove and a connecting groove. The first sliding groove and the second sliding groove are both arranged along the length direction of the rake arm. The connecting groove is arranged along the circumferential direction of the rake arm. The two ends of the connecting groove are respectively communicated with the first sliding groove and the second sliding groove. When the sliding block is located in the first sliding groove, the scraping blade abuts against the drying disk.

[0009] The utility model is further configured as follows: the first slide groove is located at one end of the slide groove close to the main shaft, and the length of the first slide groove is equal to half the length of the slider.

[0010] The utility model is further configured as follows: the length of the mounting sleeve is equal to the length of the rake arm; a threaded hole is provided on the side of the rake arm facing away from the main shaft; a threaded column is threadedly connected in the threaded hole; and one end of the threaded column is fixedly connected to a resistance column.

[0011] The present invention is further configured as follows: the diameter of the abutment column is larger than the diameter of the mounting sleeve, and friction lines are provided on the outer peripheral wall of the abutment column.

[0012] In summary, the utility model has the following beneficial effects: when people need to replace the scraper near the main shaft position, people slide the mounting sleeve back to the main shaft direction until the mounting sleeve slides to the limit position. At this time, all the rake leaves on the mounting sleeve are pulled out of the drying plate. At this time, there is enough space above and below the rake leaves. At this time, people can directly use tools to unscrew the bolts under the rake leaves and directly replace the scraper blades on the rake leaves. After replacing the scraper blades, people slide the mounting sleeve back to its original position. This arrangement makes it unnecessary to remove the rake leaves and directly replace the scraper blades on the rake leaves, which is convenient for people to maintain the rake leaves.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] A disc type continuous dryer that is easy to maintain, such as Figure 1As shown, it includes a main shaft 1 and several drying trays 2. The several drying trays 2 are arranged along the length direction of the main shaft 1. A number of rake arms 3 are fixedly connected to the main shaft 1. An installation sleeve 4 is sleeved on the rake arms 3. A number of rake blades 5 are installed on the installation sleeve 4. The several rake blades 5 are arranged in a linear array along the length direction of the installation sleeve 4. The lower end of the rake blade 5 is bolted with a scraping blade 6. The installation sleeve 4 can slide away from the main shaft 1 and can drive all the rake blades 5 out of the drying tray 2. In this embodiment, the number of rake arms 3 fixed on the main shaft 1 on each layer of drying tray 2 is four. When people need to replace the scraping blade near the position of the main shaft 1, people slide the installation sleeve 4 in the direction away from the main shaft 1 until the installation sleeve 4 slides to the limit position. At this time, all the rake blades 5 on the installation sleeve 4 are pulled out of the drying tray 2. At this time, there is enough space above and below the rake blade 5. At this time, people can directly use tools to unscrew the bolts below the rake blade 5 and directly replace the scraping blade 6 on the rake blade 5. After replacing the scraping blade 6, people slide the installation sleeve 4 back to its original position. Such a setting makes it unnecessary to remove the rake blade 5 and directly replace the scraping blade 6 on the rake blade 5, which is convenient for people to maintain the rake blade 5.

[0019] As Figure 1 and Figure 2 shown, a sliding groove is formed on the outer peripheral wall of the rake arm 3. A sliding block 7 located in the sliding groove is fixedly connected to the inner wall of the installation sleeve 4. The end of the sliding groove away from the main shaft 1 is not communicated with the outside. The installation sleeve 4 slides along the sliding groove. Such a setting makes the sliding block 7 not slide out of the sliding groove, and due to the limitation of the sliding groove, it is not easy for the installation sleeve 4 and the rake arm 3 to rotate relative to each other. The sliding groove includes a first chute 8, a second chute 9 and a connecting groove 10. The first chute 8 and the second chute 9 are both arranged along the length direction of the rake arm 3. The connecting groove 10 is arranged along the circumferential direction of the rake arm 3. The two ends of the connecting groove 10 are respectively communicated with the first chute 8 and the second chute 9. When the sliding block 7 is located in the first chute 8, the scraping blade 6 abuts against the drying tray 2. During the sliding process of the installation sleeve 4, the sliding block 7 originally located in the first chute 8 will slide in the direction away from the main shaft 1. When the sliding block 7 abuts against the inner wall of the first chute 8, people rotate the installation sleeve 4 so that the sliding block 7 slides into the second chute 9 along the connecting groove 10. During this process, the scraping blade 6 originally in contact with the drying tray 2 rotates upward, so that the scraping blade 6 no longer contacts the drying tray 2. Such a setting makes the resistance that the installation sleeve 4 needs to overcome decrease during the process of the sliding block 7 moving along the second chute 9, so as to facilitate the sliding of the installation sleeve 4. The first chute 8 is located at the end of the sliding groove close to the main shaft 1. The length of the first chute 8 is equal to half of the length of the sliding block 7. Such a setting makes the sliding distance of the sliding block 7 in the first chute 8 small, so that the time required for people to apply force is also short. Secondly, the length of the first chute 8 can already limit the sliding block 7 well, so as to ensure that the installation sleeve 4 will not rotate on the rake arm 3.

[0020] As Figure 3As shown, the length of the mounting sleeve 4 is equal to the length of the rake arm 3. A threaded hole 11 is provided on the side of the rake arm 3 facing away from the main shaft 1. A threaded column is threadedly connected to the threaded hole 11. One end of the threaded column is fixedly connected to a resistance column 12. When the side of the mounting sleeve 4 facing away from the main shaft 1 is flush with one side of the rake arm 3, the threaded column is threadedly connected to the threaded hole 11 until one side of the resistance column 12 is tightly pressed against the mounting sleeve 4. At this time, the mounting sleeve 4 is pressed against the resistance column 12, so that the mounting sleeve 4 and the rake arm 3 are not prone to relative sliding. At the same time, the slider 7 is also pressed tightly against the slide groove 8, ensuring the firmness of the fixing of the mounting sleeve 4 and the rake arm 3. The diameter of the interference column 12 is larger than the diameter of the mounting sleeve 4, and the outer peripheral wall of the interference column 12 is provided with friction lines. The diameter of the interference column 12 is large, so when people hold the outer wall of the interference column 12, their hands do not contact the mounting sleeve 4, ensuring that the force is applied to the interference column 12, and the outer wall of the interference column 12 is provided with friction lines, thereby increasing the friction between the hand and the outer wall of the interference column 12, making it easier for people to apply force.

[0021] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
