Description

Technical Field

[0001] This invention relates to the field of ash conveying silo pump technology, and in particular to an anti-clogging mechanism for a pneumatic ash conveying silo pump. Background Technology

[0002] Thermal power generation utilizes the heat energy generated during the combustion of combustibles and converts it into electrical energy through a power generation device. Combustibles are placed in a fluidized bed combustion furnace and burned into slag, which needs to be discharged. The slag treatment area is usually far from the combustion furnace, so the slag needs to be transported to a designated ash silo for further processing via pneumatic conveying. During the slag dust conveying process, a silo pump is usually set up to receive the slag dust after combustion. Existing silo pumps have problems with poor discharge, which can lead to material blockage. This slag dust tends to accumulate and clump around the bottom of the silo pump, making it difficult to clean.

[0003] In view of the above, we provide a pneumatic ash conveying silo pump anti-clogging mechanism to solve the above problems. Summary of the Invention

[0004] In response to the above situation, the present invention provides a pneumatic ash conveying silo pump anti-clogging mechanism. The cutting blade of the mechanism can be released during the downward movement of the lower pressure frame to achieve the effect of cutting solid clumps, and at the same time, it can create an impact effect, making the clumps easy to fall off.

[0005] A pneumatic ash conveying silo pump anti-clogging mechanism includes a silo body, a support pipe provided on the side of the silo body, a pressure pipe slidably provided on the lower surface of the support pipe, a pressure frame rotatably provided on the surface of the pressure pipe, a first spring provided between the support pipe and the pressure pipe, a folding mechanism provided on the side of the pressure frame, the folding mechanism including a cutting blade, a second spring and a release bar, the cutting blade rotatably provided on the side of the pressure frame, the release bar slidably provided on one side of the pressure frame, a locking block overlapping the middle of the cutting blade, the locking block slidably provided on the side of the pressure frame, a rotating blade rotatably provided at the bottom of the pressure frame, the rotating blade having an internal ejection channel, a buffer ring slidably provided on the upper surface of the release bar, and a control spring provided between the release bar and the buffer ring.

[0006] The beneficial effects of the above technical solution are as follows:

[0007] The cutting blade in this design can be released as the pressure frame moves downwards, effectively cutting solid clumps and creating an impact effect that facilitates the falling of clumps. The overall position of the pressure frame can also be adjusted, retracting the cutting blade as it moves upwards. The rotating blade can cut vertically downwards during downward movement, removing dust accumulated at the bottom of the chamber. As it moves upwards, it rotates horizontally, moving some dust to the top for unblocking. Furthermore, during rotation, the spray channel can be adjusted from a vertical spray to horizontal sprays on both sides, corresponding to the locations of the cut clumps and facilitating the blowing of solid clumps off the side walls of the chamber.

[0017] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 8 As will be clearly shown in the detailed description of the embodiments, all structural contents mentioned in the following embodiments are based on the accompanying drawings.

[0018] This embodiment provides an anti-clogging mechanism for a pneumatic ash conveying silo pump, as shown in the attached figure. Figure 1-8 As shown, the instruction manual is attached. Figure 1 This is the overall structural diagram of the solution, attached to the instruction manual. Figure 1 The image only shows a portion of compartment 1, not the actual compartment 1. The image only shows the bottom of compartment 1. (Instruction manual included.) Figure 2 This is a cut-out view of one side of compartment 1. (See instruction manual attached.) Figure 3 The chamber 1 has been concealed, and the length of the support tube 2 has been shortened to prevent obstructing the view of the overall diagram. (Instruction manual attached.) Figure 4 The instruction manual includes a top-down view of support tube 2. Figure 3 All subsequent support tubes 2 have been shortened, because... (The sentence is incomplete and requires more context to translate accurately.) Figure 1 The middle support tube 2 is very long, which affects the viewing experience. Therefore, it is attached to the instruction manual. Figure 3 The length of support tube 2 has been shortened. (See instruction manual attached.) Figure 5 The support tube 2 was cut in the middle. (See instruction manual attached.) Figure 6 Included with instruction manual Figure 5 Partial view of the image, and included in the instruction manual. Figure 5 The text contains corresponding dividing lines; the instruction manual is attached. Figure 8 Cutting from another angle for support tube 2, see instruction manual attached. Figure 5 To cut towards the center, the instruction manual is attached. Figure 8 To cut facing right, refer to the instruction manual. Figure 3For reference, in this design, the support pipe 2 is fixedly installed on one side of the chamber 1. The support pipe 2 has two functions: first, it can support the lower pressure pipe 3; second, it can act as a gas delivery pipe. One side of the support pipe 2 needs to be connected to an external air outlet device so that gas can enter the support pipe 2. The lower pressure pipe 3 is slidably installed on the lower surface of the support pipe 2. The lower pressure pipe 3 and the support pipe 2 are sealed and sliding (there is a No. 1 spring 5 between them, which is used to reset the lower pressure pipe 3. Under the action of gas, the lower pressure pipe 3 will move downward, and after the gas is discharged, it will be reset by the pull of the No. 1 spring 5). The support pipe 2 has a corresponding slide for the lower pressure pipe 3, so that the lower pressure pipe 3 can slide vertically downward. At the bottom of the slide, there is a... A release port 30 allows gas to travel from the support tube 2 to the inside of the pressure tube 3. Since the gas entering through the support tube 2 cannot enter the pressure tube 3 from the top, it can only enter through the top port 31. This means that as gas continuously enters through the support tube 2, the internal pressure continuously increases due to the inability to expel the gas, controlling the downward movement of the pressure tube 3. This achieves the effect of adding gas to cause the pressure frame 4 to move downward. This solution utilizes the sealing property of the gas to achieve downward pressure. Once the pressure tube 3 reaches the release port 30, the gas will instantly flow from the release port 30 through the top port 31 and then to the bottom port 32 (because the bottom of the pressure tube 3 also cannot expel gas, although the insertion rod 18 is slidably set). At the bottom of the pressure tube 3 (but the two are sealed), it is set together with the bottom opening 32 as the corresponding opening 33. The corresponding opening 33 is an annular notch, opened at the inner arc of the pressure frame 4. The pressure frame 4 is sealed and rotated to the bottom of the pressure tube 3 and cannot be disengaged. Therefore, a sealing period is formed between the bottom of the pressure tube 3 and the pressure tube 3. This sealed area is finally delivered to the bottom block 34. The bottom block 34 is integrally set at the bottom of the pressure frame 4 and is located at the rotation center of the pressure frame 4. It corresponds to the rotatable setting of the insertion rod 18. The gas enters the interior of the bottom block 34 and reaches the ejection channel 11 to achieve the effect of gas ejection. Because the rotating blade 10 is rotatably set in the bottom block 34, and the middle part of the rotating blade 10 is a hollow tube, the hollow tube Corresponding through holes are provided on both sides, allowing gas to enter the interior of the ejection channel 11. The middle part of the rotating blade 10 and the bottom block 34 are sealed during rotation, ensuring that the gas ultimately reaches the ejection channel 11. In summary, the gas first compresses the pressure pipe 3, causing it to move downwards and accumulate. The pressure generated by the gas gradually drives the pressure pipe 3 downwards until it reaches the vicinity of the release port 30. From the release port 30, it moves to the top port 31, then to the bottom port 32, then to the corresponding port 33, and finally to the bottom block 34, ultimately reaching the ejection channel 11 to release the gas. During the gas release process, the gas also has an impact force. This design utilizes the downward movement and resetting capability of the pressure pipe 3 to create a pressure frame 4, which is rotatably positioned at the bottom of the pressure pipe 3.Most of the structure in this design is based on the movable distance of the pressure tube 3. First, let's introduce the rotating ring 22. The rotating ring 22 is rotatably positioned above the pressure frame 4 and has an anti-detachment structure, ensuring it cannot be separated from the pressure frame 4. The two can rotate together. This design relies on the rotation of the rotating ring 22 to adjust the position of the pressure frame 4. The outer surface of the rotating ring 22 has a rotating groove 23, which is an arc-shaped, sloping groove. The round rod 24 fits perfectly into the rotating groove 23. When the pressure frame 4 moves downwards, the rotating ring 22 does not rotate; it only moves the round rod 24 downwards. Just before reaching the bottom, a compression spring 25 is located on one side of the round rod 24. Note that this compression spring 25 is not connected to the round rod 24; one end of the compression spring 25 is fixedly mounted on the support tube 2, extending from one side of the support tube 2. The round rod 24 is positioned on both sides to limit its sliding distance on the support tube 2. The bottom of the compression spring 25 is located on the support tube 2, while the top awaits the downward movement of the round rod 24 to compress it. As described above, when the lower pressure tube 3 reaches the bottom, the compression spring 25 compresses, causing the rotating ring 22 to rotate. This rotation of the rotating ring 22 drives the lower pressure frame 4 to rotate. (A horizontal block 26 is slidably positioned on the edge of the rotating ring 22. One side of the horizontal block 26 has a small return spring, and the other side of the horizontal block 26 overlaps the lower pressure frame 4, forming a unidirectional rotation. That is, when the lower pressure tube 3 moves downward, it drives the lower pressure frame 4 to rotate; when the lower pressure frame 4 returns to its original position, the horizontal block 26 slips on the lower pressure frame 4, preventing it from moving. The spring on one side of the horizontal block 26 contacts the lower pressure frame 4. See the attached instruction manual.) Figure 6 As shown, in summary, the lower pressure frame 4 will rotate to adjust its position at the end of its downward movement, and will remain unchanged when it moves upward (to ensure the stability of the lower pressure frame 4 in this design, see the attached manual). Figure 6 A raised hemispherical block is provided on the left side of label 3. This hemispherical block is inserted into the bottom of the pressure frame 4. That is, the bottom of the pressure frame 4 has a circular groove corresponding to the hemispherical block. There are multiple circular grooves, and they are arranged in an array on the bottom of the pressure frame 4. The angle of two adjacent grooves corresponds to the left and right span angle of the rotation groove 23, which enables the pressure frame 4 to rotate stably and stop. In summary, the pressure tube 3 can move downward and reset. During the downward movement, the pressure frame 4 rotates at the bottom and can release gas toward the ejection channel 11.

[0019] This section introduces the core structure of this design, which is the cutting blade 6. The cutting blade 6 is rotatably mounted on the side of the lower pressure frame 4, and has a No. 7 spring on one side. The No. 7 spring is a torsion spring, which can rotate and return to its original position, as shown in all the attached diagrams of this design. At this time, the No. 7 spring is in a torsion state, that is, a charged state, as shown in the instruction manual. Figure 6 As shown, once released, it rotates to the left. Because a sliding latch 9 is located in the middle of the cutting blade 6, this latch 9 is what keeps the cutting blade 6 stable. A ratchet is located in the middle of the cutting blade 6. The ratchet and latch 9 form a one-way mechanism. To release, the latch 9 needs to move upwards. In this design, during the downward movement of the lower pressure frame 4, the release bar 8 remains stationary before moving together with the lower pressure frame 4. This is because the release bar 8 is slidably mounted on the lower surface of the buffer ring 12, and a control spring 13 is located between them. The control spring 13 is difficult to compress, so when the lower pressure frame 4 moves downwards, the release bar 8 remains stationary immediately. The release bar 8 will move upwards relative to the lower pressure frame 4 (because the lower pressure frame 4 moves downwards while the release bar 8 remains stationary). The release bar 8 will push against the latch 9 and move upwards, achieving the effect of releasing the cutting blade 6. The cutting blade 6 will rotate under the elastic force of the second spring 7 and contact the edge of the chamber 1, cutting the solid material accumulated on the edge of the chamber 1. The cutting blade 6 not only cuts the solid residue but also impacts the surface of the chamber 1, making it easier for the cut solid residue to fall off. This means the cutting blade 6 releases itself during its initial downward movement. Because the release bar 8 has limited sliding distance on the lower pressure frame 4, the control spring 13 is compressed after the cutting blade 6 is released. This complies with the downward movement of the cutting blade 6 (a small spring above the locking block 9 allows for reset). When the lower pressure frame 4 returns after moving downwards, the control spring 13 first returns to its original position (during this return process, the release bar 8 remains unchanged on the lower pressure frame 4; it only moves downwards relative to the lower pressure frame 4 when it reaches the top). As described above, this is equivalent to the lower pressure frame 4 moving upwards; this is equivalent to it moving downwards. This downward movement allows the side strip 21 on one side of the release bar 8 to push against the cutting blade 6 and rotate back to its original position. This is because there is an integrally formed strip on one side of the middle of the cutting blade 6, which corresponds to the side strip 21. This strip is described in the instruction manual. Figure 6 As shown in the diagram, on one side of the middle of the cutting blade 6, this strip can be extended to facilitate the downward movement of the side strip 21. The downward pressing of the side strip 21 corresponds to the instruction manual attached. Figure 6The position of the cutting blade 6 is such that it rotates back to its original state. The locking block 9 is also pushed by the surface above the side strip 21. The two are offset in the middle, which does not affect the normal pushing. Because one side of the locking block 9 extends to the right and downwards, the side strip 21 pushes the downward extension, causing the locking block 9 to move upwards. This is the function of the side strip 21: it can push the locking block 9 upwards and reset the cutting blade 6 downwards. In summary, when the cutting blade 6 moves downwards, it first releases the cutting and then the tail end of the upward movement resets. The buffer ring 12 is rotatably set on the support tube 2. The support tube 2 only ensures the position of the buffer ring 12. Since the lower pressure frame 4 can rotate, the buffer ring 12 is set so that it can rotate on the support tube 2 to prevent affecting the rotation of the lower pressure frame 4. The extrusion frame 27 is set below the cutting blade 6. The extrusion frame 27 is slidably set on the side of the lower pressure frame 4. The extrusion frame 27 is driven to move downwards by the release of the cutting blade 6. Because there is a triangle extending from the side of the cutting blade 6, this triangle pushes the extrusion frame 27 directly above it. (See the attached instruction manual.) Figure 3 As shown, the extrusion frame 27 moves downwards, with the rotating blade 10 positioned directly below it. A clamping plate 28 slides on the surface of the extrusion frame 27, and its downward movement scrapes away dust from the rotating blade 10. A No. 5 spring 29 is positioned between the extrusion frame 27 and the lower pressure frame 4 for resetting. A transverse spring is also positioned between the clamping plate 28 and the extrusion frame 27. This transverse spring allows the clamping plate 28 to reset laterally while pressing on the extrusion frame 27. Since the rotating blade 10 can rotate, this transverse spring prevents interference with its rotation. The transverse block 26 is actually a certain distance from the top of the rotating blade 10. (See the attached instruction manual for this solution.) Figure 3 The displayed distance is very short, but it is not; it has a distance at one end. Finally, let's introduce the rotating blade 10 of this design. The rotating blade 10 can rotate 90 degrees. The rotating blade 10 does not change its angle when moving downwards; it only rotates 90 degrees to make it flat when it reaches the bottom. This is because the middle of the rotating blade 10 has a gear that meshes with the insertion rod 18. The up-and-down movement of the insertion rod 18 allows the rotating blade 10 to adjust its position. When the pressing frame 4 moves downwards, the top of the insertion rod 18 drives the driving bar 15 downwards. Since the driving bar 15 has a limited sliding distance, it cannot continue to drive after reaching a certain distance. At this point, the rotating block 16 twists. One side of the rotating block 16 has a fourth spring 20, which is a torsion spring. The elastic force of the fourth spring 20 is greater than (a sixth spring is set between the driving bar 15 and the inner bar 14; the sixth spring is not shown in the diagram, but is only shown in the diagram, as per the instruction manual). Figure 8As shown, the elastic force of spring number six initially compresses only spring number six under the action of insertion rod 18, until the sliding distance between inner bar 14 and driving bar 15 can no longer be traversed. At this point, spring number four 20 will twist, achieving the effect of the top of insertion rod 18 disengaging from inclined block 17. Then, under the action of spring number three 19, insertion rod 18 will return to its original position, that is, rotating blade 10 will rotate. Spring number three 19 is attached to the instruction manual. Figure 8 In the stretched state, to summarize, the rotating blade 10 rotates at the end of the downward movement of the lower pressure frame 4 (releasing the insertion rod 18, which moves downward on the bottom block 34, causing the rotating blade 10 to rotate). After the lower pressure frame 4 moves upward, the cutting blade 6 will continue to move horizontally upward. Finally, the insertion rod 18 returns to above the inclined block 17. (Instruction manual attached) Figure 7 and 5The insertion rods 18 are all at the top. Since there is a distance between the insertion rods 18 and the inclined block 17, the insertion rods 18 will move downwards under the action of the third spring 19. At this point, the rotating blade 10 is horizontal (shown as vertical in the attached diagram). For ease of understanding, this solution renders this state as static. That is, the third spring 19 needs to pull the insertion rods 18 downwards, and the rotating blade 10 is horizontal, not vertical as shown in the diagram. This is because the elastic force of the third spring 19 is less than that of the sixth spring to connect the extrusion plate and the clamping plate 28. Furthermore, the rotating blade 10 is not released when the third spring 19 is stretched, which corresponds to the horizontal position of the rotating blade 10. One side of the inclined block 17 is an inclined surface corresponding to the cone shape on the upper side of the insertion rod 18. The design facilitates the compression of the inclined block 17. One side of the inclined block 17 has a small spring for return. To ensure stable operation, a drive gear 35 is installed inside the support rod. The drive gear 35 controls the up-and-down movement of the pressure tube 3, replacing gas-driven operation for greater stability. The drive gear 35 is only an alternative in this design. One side of the drive gear 35 needs to be equipped with a motor to drive its rotation. The internal strip 14 and the pressure tube 3 are sealed and slide smoothly. In summary, the effect of this design is that the cutting blade 6 can be released during the downward movement of the pressure frame 4, achieving the effect of cutting solid lumps. Simultaneously, it creates an impact effect, making the lumps easier to fall off. It also allows adjustment of the overall position of the pressure frame 4, retracting the cutting blade 6 during upward movement and rotating the blade 10. It can cut vertically downwards when moving downwards, cutting away dust accumulated at the bottom of the chamber 1. During upward movement, it can rotate horizontally, moving some dust to the top for unblocking. During rotation, the spray channel 11 can be adjusted from vertical spray to horizontal spraying on both sides, corresponding to the location of the solidified clumps it encounters, facilitating the blowing away of solid clumps from the side wall of the chamber 1.
