Detailed Implementation

[0037] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0038] Example 1: As Figures 1-11 As shown, a scraper cleaning device includes:

[0039] Base 1;

[0040] Fixing frame 6, which is mounted on the base 1;

[0041] A fixed ring seat 7 is connected to a fixed frame 6. Multiple fixed plates 19 are hinged to the fixed ring seat 7 along the circumferential direction. A surrounding plate 25 is fixedly connected to the fixed plate 19. The surrounding plate 25 is adapted to form a drying chamber when it rotates to a closed state around the hinge point of the fixed ring seat 7 and the corresponding fixed plate 19, and to open the drying chamber when it rotates to an open state.

[0042] Rotary ring 20 is rotatably connected in the fixed ring seat 7;

[0043] Multiple scraper assemblies, each scraper assembly including a connecting rod assembly and a scraper 22, the scraper 22 being mounted on the lower part of the connecting rod assembly, the connecting rod assembly being movably connected to the rotating ring 20, and the connecting rod assembly being adapted to move up and down relative to the rotating ring 20;

[0044] A circumferential rotation drive assembly 12 is connected to multiple connecting rod assemblies and is used to drive the rotating ring 20 and the connecting rod assemblies on the rotating ring 20 to rotate circumferentially, the connecting rod assemblies being adapted to scrape the inner wall of the enclosure 25 when rotating circumferentially;

[0045] A vertical movement assembly connected to multiple connecting rod assemblies for driving the connecting rod assemblies to move vertically relative to the rotating ring 20;

[0046] A scraper cleaning assembly is provided for each scraper 22. The scraper cleaning assembly is movably mounted on the corresponding scraper 22. The scraper cleaning assembly is adapted to move circumferentially relative to the enclosure 25 and be axially limited when the enclosure 25 is rotated to the closed state. The scraper cleaning assembly is adapted to clean the corresponding scraper 22 when the connecting rod assembly moves up and down relative to the rotating ring 20.

[0047] Specifically, in this embodiment, the connecting rod assembly may also be provided with stirring blades to agitate the material in the drying chamber;

[0048] In this embodiment, the embodiment can be applied to a drying equipment. The enclosure 25 is rotated to a closed state around the hinge of the fixed ring seat 7 and the corresponding fixed plate 19, so that multiple enclosures 25 form a drying chamber. The material to be dried is sent into the drying chamber and heated. Then, the circumferential rotation drive assembly 12 drives the rotating ring 20 and the connecting rod assembly on the rotating ring 20 to rotate circumferentially. The scraper 22 scrapes the inner wall of the enclosure 25 and stirs the material through the connecting rod assembly and the scraper 22 to fully dry the material. When the scraper 22 rotates circumferentially, the up-and-down moving assembly can drive the connecting rod assembly to move up and down relative to the rotating ring 20, thereby moving the scraper 22 up and down. The scraper cleaning assembly cleans the corresponding scraper 22.

[0049] Specifically, such as Figure 2 , 5As shown, the connecting rod assembly has a top rod 15, a movable rod 13, and a second key rod 21. The lower end of the top rod 15 is connected to the upper end of the movable rod 13, and the lower end of the movable rod 13 is connected to the second key rod 21. The second key rod 21 passes through the rotating ring 20, and the scraper 22 is mounted on the second key rod 21.

[0050] Specifically, in this embodiment, such as Figure 1 , 3 As shown in Figures 4 and 5, the circumferential rotation drive assembly 12 includes a motor 10, a gear 1201, and a gear ring 1205. The gear 1201 meshes with the gear ring 1205 and is connected to the motor 10. The connecting rod assembly is mounted circumferentially on the gear ring 1205 and moves up and down relative to the gear ring 1205.

[0051] Specifically, the movable rod 13 in the connecting rod assembly passes through the toothed ring 1205; specifically, the toothed ring 1205 can be rotatably connected to the fixed ring seat 7 to support the toothed ring 1205; of course, the toothed ring 1205 can also be supported in the following ways: such as Figure 7 , 8 As shown, the gear ring 1205 is connected to the gear 1201 through an axial limiting mechanism. The axial limiting mechanism includes a first limiting block 1202, a second limiting block 1204, and a connecting plate 1203. The gear 1201 is provided with a first limiting sliding groove in the circumferential direction, and the gear ring 1205 is provided with a second limiting sliding groove in the circumferential direction. The first limiting block 1202 is limited to slide in the first limiting sliding groove, and the second limiting block 1204 is limited to slide in the second limiting sliding groove. The connecting plate 1203 connects the first limiting block 1202 and the second limiting block 1204.

[0052] In this embodiment, the rotation of the motor 10 drives the gear 1201 to rotate, which in turn drives the gear ring 1205 to rotate, which in turn drives the connecting rod assemblies on the gear ring 1205 to rotate circumferentially, thereby driving the scraper 22 to rotate circumferentially to scrape the inner wall of the enclosure 25.

[0053] Specifically, such as Figures 1-5 As shown, the up-and-down moving assembly includes an up-and-down guide member 16 and a second spring 14. The up-and-down guide member 16 has protrusions that are spaced apart circumferentially and protrude downwards. The up-and-down guide member 16 is adapted to contact and cooperate with the upper end of the connecting rod assembly. The second spring 14 acts on the connecting rod assembly. The connecting rod assembly is adapted to reciprocate up-and-down movement under the action of the up-and-down guide member 16 and the second spring 14 when the connecting rod assembly rotates circumferentially.

[0054] Specifically, the upper and lower guide members 16 cooperate with the upper end of the top rod 15 in the connecting rod assembly, and the second spring 14 is sleeved on the connecting rod assembly and is located between the connecting rod assembly and the toothed ring 1205.

[0055] Specifically, such as Figure 2 As shown, the lower end of the push rod 15 is provided with a stop wall, and the second spring 14 is disposed between the stop wall and the toothed ring 1205.

[0056] When the circumferential rotation drive assembly 12 drives each connecting rod assembly to rotate circumferentially, the upper part of the connecting rod assembly cooperates with the upper and lower guide members 16. When it contacts the protrusion of the upper and lower guide members 16, the connecting rod assembly moves downward and the scraper 22 also moves downward. When it rotates to the interval of the upper and lower guide members 16, the connecting rod assembly moves upward under the action of the second spring 14.

[0057] Specifically, such as Figure 10 , 11 As shown, the scraper cleaning assembly includes at least one scraping sleeve 2603, which at least cooperates with the scraping part of the scraper 22. When the scraper 22 moves up and down, the scraping sleeve 2603 scrapes the scraper 22.

[0058] Specifically, the scraper 22 is connected to the corresponding connecting rod assembly via the scraper connecting assembly 26. The connecting assembly 26 includes at least one mating groove 2601 disposed on the connecting rod assembly and at least one mating block 2602 connected to the scraper 22. The mating block 2602 is embedded in the corresponding mating groove 2601. By pulling the scraper 22, the mating block 2602 can be pulled out from the inside of the mating groove 2601, thereby enabling convenient docking and replacement of the scraper 22.

[0059] Specifically, the docking block 2602 is made of rubber and is shaped like a spherical cap. The docking blocks 2602 are evenly distributed on the scraper 22. The evenly distributed docking blocks 2602 can ensure stable docking of the scraper 22 and ensure the stability of the device during docking.

[0060] Example 2: This example, based on Example 1, also has the following structure: (e.g.) Figure 1 , 2 As shown, the scraper cleaning device also includes a enclosure plate rotating assembly connected to the enclosure plate 25 to drive the enclosure plate 25 to rotate.

[0061] Specifically, the enclosure rotation assembly includes a hydraulic cylinder 8, a pressure plate 9, and a linkage mechanism corresponding to the enclosure 25. The hydraulic cylinder 8 is installed on the upper part of the fixed frame 6, the pressure plate 9 is installed on the piston rod of the hydraulic cylinder 8, and the linkage mechanism connects the pressure plate 9 and the enclosure 25.

[0062] In this embodiment, the hydraulic cylinder 8 is activated, and the pressure plate 9 moves upward or downward. When the pressure plate 9 moves upward, it drives the surrounding plate 25 to rotate upward through the linkage mechanism. When it rotates to the open state, the drying chamber is opened. When the pressure plate 9 moves downward, it drives the surrounding plate 25 to rotate downward through the linkage mechanism. When it rotates to the closed state, the drying chamber is formed.

[0063] Specifically, such as Figure 2 As shown, the linkage mechanism includes a connecting handle 18 and a traction steel rope 17. The connecting handle 18 is fixed on the corresponding fixing plate 19. One end of the traction steel rope 17 is connected to the corresponding connecting handle 18, and the other end is connected to the pressure plate 9.

[0064] Specifically, such as Figure 1 As shown, the motor 10 can be fixedly mounted on the pressure plate 9. The output shaft of the motor 10 is connected to the first key rod 11, and the gear 1201 is connected to the first key rod 11. During the process of the motor 10 moving up and down with the pressure plate 9, the first key rod 11 can move up and down relative to the gear 1201.

[0065] Example 3: This example, based on Example 1, Example 2, or Example 3, also has the following structure: (e.g.) Figure 1 As shown, the upper end of the enclosure 25 is provided with a first sealing gasket 27, the lower end of the enclosure 25 is provided with a second sealing gasket 28, and the base 1 is equipped with a top block 5 at the lower end of the drying chamber. A first spring 4 is provided between the top block 5 and the base 1.

[0066] Specifically, such as Figure 6 As shown, a groove 3 is provided in the middle of the base 1, and the top block 5 is installed in the groove 3. The outer wall of the top block 5 and the inner wall of the groove 3 fit together, and the fitting groove 3 and the top block 5 allow the top block 5 to move up and down smoothly.

[0067] Specifically, when the enclosure 25 is rotated to the closed state, the second sealing gasket 28 at the lower end of the enclosure 25 is pressed against the top block 5, and the first sealing gasket 27 at the upper end and the second sealing gasket 28 at the lower end of the enclosure 25 are both in a pressed state, thereby ensuring the sealing effect of the enclosure 25 and preventing heat loss during the drying process.

[0068] Of course, a sealing element can also be installed between adjacent enclosure panels 25 to achieve a sealing effect.

[0069] Example 4: This example, based on any one of Examples 1 to 3, further has the following structure:

[0070] like Figure 5 As shown, an extension plate 23 is installed at the lower end of the connecting rod assembly, and a heating component is installed on the extension plate 23. The drying chamber is heated by the heating component. The heating component is existing technology and will not be described in detail in this embodiment. The heating component can be an electric heating tube 24, and the diameter of the electric heating tube 24 decreases from top to bottom. Of course, the drying chamber can also be heated by other means.

[0071] Specifically, such as Figure 7As shown, all heating components are staggered in the circumferential direction, specifically, they can form an involute spiral structure in the circumferential direction. Since the line connecting the centers of the bottom of each electric heating tube 24 is an involute spiral, when the electric heating tube 24 rotates, each electric heating tube 24 can pass over various positions inside the drying chamber enclosed by the surrounding plate 25, thereby improving the efficiency of heating and drying materials. During the drying process, due to the gravity of the material, the material piled up at the bottom is relatively compact. Therefore, the heating efficiency of the bottom of the material can be improved by using electric heating tubes 24 with a truncated cone structure whose diameter decreases from top to bottom.

[0072] Example 5: This example, based on any one of Examples 1 to 4, further has the following structure:

[0073] like Figure 1 As shown, a collection component 2 is provided on the outer side of the base 1. The collection component 2 is used to collect the material in the drying chamber when the enclosure 25 is rotated to the open state to open the drying chamber.

[0074] like Figure 1 As shown, the collection assembly 2 includes a first collection cylinder 201 and a second collection cylinder 202 that are fitted and installed on the outside of the base 1. The first collection cylinder 201 and the second collection cylinder 202 are symmetrically distributed on both sides of the base 1. A first connecting block 203 is fixedly connected to the second collection cylinder 202, and a second connecting block 204 is fixedly connected to the first collection cylinder 201. A locking rod 205 is provided through the inside of the first connecting block 203 and the second connecting block 204. In use, the dried material can be collected through the first collection cylinder 201 and the second collection cylinder 202. By pulling out the locking rod 205 inside the first connecting block 203 and the second connecting block 204, the first collection cylinder 201 and the second collection cylinder 202 can be separated.

[0075] First, such as Figures 1-8As shown, the base 1 is used to support the entire device. When the enclosure 25 is rotated to the closed position on the fixed ring 7 via the fixed plate 19, the first sealing gasket 27 and the fixed ring 7 are kept in a pressed state. The bottom of the second sealing gasket 28 abuts against the top block 5. The first spring 4 in the groove 3 supports the top block 5, so that the top block 5 and the second sealing gasket 28 are kept in a pressed state, thereby keeping the bottom of the enclosure 25 closed after closing. The wet material is poured into the drying chamber. When it is necessary to clean the scraper 22, the hydraulic cylinder 8 on the extended fixed frame 6 can be used. When the hydraulic cylinder 8 extends, it drives the pressure plate 9 to move downward into place. The upper and lower guide members 16 on the pressure plate 9 can abut against the top rod 15. The motor 10 drives the first key rod 11 to rotate. When the first key rod 11 rotates and moves up and down, it drives the gear 1201 to rotate. The gear 1201 drives the gear ring 1205 to rotate. When the gear ring 1205 rotates, it drives the push rods 15 at various positions to perform circular motion. The wave-shaped upper and lower guide members 16 enable the push rods 15 to move up and down intermittently during circular motion, thereby causing the second key rod 21 and the scraper 22 to move up and down intermittently as a whole. This allows the scraping sleeve 2603 to control the second key rod 21 and the scraper. The scraper 22 has the function of cleaning the outer surface of the scraper 22. While the scraper 22 is rotating, it can also clean the inner wall of the enclosure 25. Since the scraper sleeve 2603 and the enclosure 25 are slidably connected, when the second key rod 21 and the scraper 22 move up and down, the height of the scraper sleeve 2603 remains unchanged and rotates synchronously with the second key rod 21 and the scraper 22. This allows the device to clean the inner wall of the enclosure 25 with the scraper 22 and the outer wall of the second key rod 21 and the scraper 22 with the scraper sleeve 2603.

[0076] like Figures 1-5 and Figures 9-11As shown, during the rotation of the second key rod 21, the extension plates 23 and electric heating tubes 24 at various locations will rotate. Since the line connecting the bottom centers of the electric heating tubes 24 at various positions is an involute spiral, when the electric heating tubes 24 rotate, the electric heating tubes 24 at various positions can pass over various positions inside the drying chamber enclosed by the surrounding plate 25, thereby improving the efficiency of the device in heating and drying materials. During the drying process, due to the gravity of the material, the material piled up at the bottom is relatively compact. Therefore, the heating efficiency of the bottom of the material can be improved by using the electric heating tubes 24 with the frustum structure. After heating, the device can move the hydraulic cylinder 8 to move the pressure plate 9 upward, pulling the connecting handle 18 and the fixing plate 19 upward with the traction steel rope 17, causing the surrounding plate 25 to rotate. After the surrounding plate 25 rotates, the storage space of the device will be opened, and the dried material will fall along the inclined surface of the base 1 into the interior of the first collecting cylinder 201 and the second collecting cylinder 202. Subsequently, by pulling out the locking rod 205 in the first connecting block 203 and the second connecting block 204, the first collecting cylinder 201 and the second collecting cylinder 202 can be disengaged, allowing them to be separated and transferred. Finally, the scraper 22 is pulled away from the second key rod 21, allowing the docking block 2602 to be pulled out from the docking groove 2601, thus enabling convenient replacement of the scraper 22.

[0077] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
