Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, referring to Figures 1 to 8 This is the first embodiment of the present invention. This embodiment provides a low-pressure fluidized pneumatic ash conveying device, which can achieve the effect of easy cleaning of the inner cavity of the ash conveying device. It includes a cleaning component 100, which includes a main component 101, a movable component 102 fixedly disposed on the main component 101, a trigger component 103 fixedly disposed on the movable component 102, and a cleaning component 104 rotatably disposed on the outer wall of the movable component 102. The main component 101 is used for ash conveying. When the main component 101 is blocked, the movable component 102 can be externally driven by a rotation drive to push the movable component 102 to the blocked position of the main component 101. The rotation drive can drive the movable component 102 to rotate. The movable component 102 can drive the cleaning component 104 to clean the blocked area through the trigger component 103.

[0031] The scraping component 200 includes an inner tube assembly 201 fixedly mounted on the movable component 102, and an elastic component 202 fixedly mounted on the outer wall of the inner tube assembly 201. It also includes an outer tube assembly 203 fixedly mounted on the inner tube assembly 201, and an output component 204 slidably mounted on the outer tube assembly 203. The output component 204 is connected to the elastic component 202. Furthermore, it includes a rotating component 205 rotatably mounted at the end of the inner tube assembly 201, connected to the movable component 102. When the movable component 102 rotates, it can drive the inner tube assembly 201 to trigger the output component 204, causing the output component 204 to scrape the blockage. Because the output component 204 has… Since there are multiple components, the blockage can be cleaned in a ring shape. The inner tube assembly 201 triggers the output assembly 204 one by one, and the reset of the output assembly 204 is driven by the elastic assembly 202. The outer tube assembly 203 is used to seal and support the output assembly 204. At the same time, the movable assembly 102 will also drive the rotating assembly 205 to clean the blockage. Thus, there is a three-stage cleaning process: the rotating assembly 205 opens up the blockage, the output assembly 204 scrapes and cleans the inner wall, and then the cleaning assembly 104 cleans the inner wall a second time, thus completing the rapid cleaning and avoiding the problem of secondary blockage caused by incomplete cleaning, thereby improving the cleaning effect.

[0032] In use, the main component 101 is used for ash conveying. When the main component 101 becomes clogged, an external rotary drive can be connected to the movable component 102, pushing the movable component 102 to the clogged position. The rotary drive causes the movable component 102 to rotate, and the movable component 102 can trigger the cleaning component 104 to clean the clogged area via the trigger component 103. When the movable component 102 rotates, it can trigger the output component 204 of the inner tube component 201, causing the output component 204 to scrape against the clogged area. Since there are multiple output components 204, the clogged area can be cleaned in a circumferential manner. Furthermore, the inner tube assembly 201 triggers the output assembly 204 one by one, and the reset of the output assembly 204 is driven by the elastic assembly 202. The outer tube assembly 203 is used to seal and support the output assembly 204. At the same time, the movable assembly 102 will also drive the rotating assembly 205 to clean the blockage. Thus, there is a three-stage cleaning process. The rotating assembly 205 opens up the blockage, the output assembly 204 scrapes and cleans the inner wall, and then the cleaning assembly 104 cleans the inner wall a second time, thus completing the rapid cleaning and avoiding the problem of secondary blockage caused by incomplete cleaning, thereby improving the cleaning effect.

[0033] In summary, the movable component 102 within the main component 101 can drive the cleaning component 104, the output component 204, and the rotating component 205 to clean the blockage in the inner cavity of the ash conveying device. This allows for cleaning and unblocking without disassembly. Furthermore, the cleaning process is carried out in a graded and step-by-step manner, resulting in a relatively clean finish and avoiding secondary blockage caused by incomplete unblocking.

[0034] Example 2, refer to Figures 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a cleaning component 100 for a low-pressure fluidized pneumatic ash conveying device, which solves the problem of blockage and difficulty in cleaning the inner cavity of the ash conveying device. It includes a main component 101 including a feeding bucket 101a and a conveying cylinder 101b fixedly disposed at the bottom of the feeding bucket 101a. It also includes a conveying pipe 101c fixedly disposed on one side of the conveying cylinder 101b and an equipment pipe 101d fixedly disposed on the other side of the conveying cylinder 101b. The connection between the conveying pipe 101c and the equipment pipe 101d and the conveying cylinder 101b is detachable, so the equipment pipe 101d can be installed on the corresponding conveying cylinder 101b.

[0035] Specifically, the active component 102 includes a moving tube 102a, strip plates 102b fixedly disposed on both sides of the moving tube 102a, a shaft 102c rotatably disposed on the inner wall of the moving tube 102a, a sealing ring 102d slidably disposed on the outer wall of the moving tube 102a, a circular block 102e fixedly disposed in the middle of the shaft 102c, and an elliptical rod 102f fixedly disposed at the end of the shaft 102c. The sealing ring 102d is connected to the equipment tube 101d. The end of the shaft 102c protrudes outside the moving tube 102a, so the end of the shaft 102c can be connected to a rotation drive.

[0036] Furthermore, the trigger assembly 103 includes a fixed tube 103a fixedly disposed at the end of the moving tube 102a, with slots 103b on both sides of the fixed tube 103a, and arc-shaped shells 103c fixedly disposed on both sides of the inner wall of the fixed tube 103a. The center points of the arc-shaped shells 103c and the fixed tube 103a are not the same. It also includes a tension spring 103d fixedly disposed on the inner wall of the arc-shaped shells 103c, and an arc-shaped plate 103e slidably disposed on the inner wall of the arc-shaped shells 103c. When the arc-shaped plate 103e slides within the arc-shaped shells 103c, it is not centered on the fixed tube 103a. The arc plate 103e slides towards the inner wall of the fixed tube 103a when it slides. The arc plate 103e is connected to the tension spring 103d. It also includes a force plate 103f fixed at the end of the arc plate 103e. The force plate 103f is adapted to the slot 103b. It also includes a trigger block 103g adapted to the force plate 103f. The trigger block 103g is connected to the round block 102e. When the trigger block 103g moves to fit the force plate 103f with the round block 102e as the center point, the trigger block 103g can abut against the force plate 103f.

[0037] Furthermore, the cleaning assembly 104 includes an outer ring 104a rotatably disposed on the outer wall of the fixed tube 103a, grooves 104b provided on both sides of the inner wall of the outer ring 104a, the grooves 104b being adapted to the force plate 103f, and a cleaning rod 104c fixedly disposed on the outer wall of the outer ring 104a.

[0038] The rest of the structure is the same as in Example 1.

[0039] In use, when the conveying pipe 101c becomes blocked, pushing the moving pipe 102a causes the movable component 102, trigger component 103, cleaning component 104, and scraping component 200 to enter the conveying pipe 101c. At this time, rotating the shaft 102c causes the circular block 102e and trigger block 103g to rotate. The trigger block 103g rotates and moves to the force plate 103f, thereby causing the force plate 103f to move. The force plate 103f then causes the arc plate 103e to move and pull the tension spring. 103d, When the arc plate 103e moves from inside the arc shell 103c, it will gradually deviate towards the inner wall of the fixed tube 103a. Therefore, the arc plate 103e will cause the force plate 103f to disengage from the contact with the trigger block 103g. As a result, the tension spring 103d will cause the arc plate 103e and the force plate 103f to reset. During this process, the force plate 103f will move in the slide groove 104b, and the force plate 103f will cause the outer ring 104a and the cleaning rod 104c to clean the inner wall of the delivery tube 101c.

[0040] In summary, since the equipment pipe 101d and the conveying pipe 101c are designed as objects, unblocking can be performed without disassembling the conveying pipe 101c when unblocking is required. Furthermore, when the tension spring 103d is driven to trigger the reset, the outer ring 104a and the cleaning rod 104c will have a reverse cleaning effect, thereby enabling bidirectional rotation to clean the inner wall of the conveying pipe 101c, thus improving the cleaning effect.

[0041] Example 3, referring to Figures 1-8 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a scraping component 200 for a low-pressure fluidized pneumatic ash conveying device, which solves the problem of low cleaning effect inside the ash conveying device. It includes an inner tube assembly 201, which includes an inner tube 201a fixedly disposed at the end of a fixed tube 103a. The inner tube 201a is provided with a through groove 201b, and multiple through grooves 201b are arranged in a ring on the inner tube 201a, and the through grooves 201b have two rows. It also includes a support plate 201c slidably disposed in the through groove 201b. The support plates 201c in the two rows of through grooves 201b are opposite each other as a group. It also includes a rubber roller 201d rotatably disposed on the support plate 201c. Each group of support plates 201c is connected to the rubber roller 201d.

[0042] Specifically, the elastic component 202 includes an elastic band 202a, which has circular holes 202b. Multiple circular holes 202b are arranged in a ring on the elastic band 202a, and there are two rows of circular holes 202b. Support rods 202c are provided in the circular holes 202b. The support rods 202c located in the two rows of circular holes 202b are arranged in a group. The component also includes a limiting roller 202d rotatably provided on the support rods 202c. Each group of support rods 202c is connected to a limiting roller 202d. The limiting roller 202d is connected to the inner tube 201a.

[0043] Furthermore, the outer tube assembly 203 includes an outer tube 203a fixedly disposed on the outer wall of the inner tube 201a. A circular groove 203b is provided in the middle of the inner wall of the outer tube 203a, and a strip groove 203c is provided on the outer wall of the outer tube 203a. The strip groove 203c is located on the outer wall of the outer tube 203a and has multiple sections. The circular groove 203b and the strip groove 203c are connected.

[0044] Furthermore, the output component 204 includes a transmission plate 204a slidably disposed within the strip groove 203c, and a scraper 204b fixedly disposed on the outside of the transmission plate 204a. The scraper 204b is made of a soft material, so that the scraper 204b can be slightly bent. It also includes a limiting strip 204c fixedly disposed at the end of the transmission plate 204a located on one side of the scraper 204b. The limiting strip 204c limits the scraper 204b to an arc-shaped state. The transmission plate 204a is connected to the elastic band 202a.

[0045] Furthermore, the rotating assembly 205 includes a conical block 205a and a connecting ring 205b fixedly disposed at the end of the conical block 205a. The connecting ring 205b is connected to the inner tube 201a. It also includes a cleaning plate 205c fixedly disposed on the conical surface of the conical block 205a. The cleaning plate 205c is provided with a guide groove 205d. The conical block 205a is connected to the shaft 102c.

[0046] The rest of the structure is the same as in Example 2.

[0047] In use, the rotation of shaft 102c drives elliptical rod 102f. Elliptical rod 102f presses against corresponding rubber roller 201d with two protruding points. Rubber roller 201d drives corresponding support rod 202c and transmission plate 204a to move outward. Transmission plate 204a drives scraper 204b to scrape the inner wall of conveying pipe 101c. During this process, transmission plate 204a pulls elastic band 202a, thereby limiting elastic band 202a with the two sets of support rods 202c and limiting roller 202d, giving elastic band 202a a strong restoring force. When elliptical rod 102f continues... During continuous rotation, the rubber roller 201d gradually resets. This process is achieved by the elastic band 202a pulling the transmission plate 204a to reset, which in turn drives the scraper 204b, support plate 201c, and rubber roller 201d to reset. This method can clean the annular area of ​​the inner wall of the conveying pipe 101c, and the scraping action can efficiently clear blockages. At the same time, the shaft 102c can drive the conical block 205a to rotate, which in turn drives the cleaning plate 205c to clear blockages. When the cleaning plate 205c clears blockages, the cleaned material can be guided through the guide groove 205d.

[0048] In summary, by slowly pushing the movable component 102 to move the scraping component 200 toward the blockage, after the rotating component 205 clears the blockage, the output component 204 can scrape the inner wall of the blockage, and after scraping, the cleaning component 104 can clean the area again, thereby improving cleaning efficiency and cleanliness, making it difficult to clog again in a short time after one cleaning.
