DETAILED DESCRIPTION

[0017] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 8 It can be clearly presented in the detailed description of the embodiments that the structural contents mentioned in the following embodiments are all referenced to the drawings in the specification.

[0018] This embodiment provides a pneumatic ash conveying silo pump anti-blocking mechanism, as shown in the attached Figure 1-8 As shown in the instruction manual, Figure 1 This is the overall structure diagram of this solution, and the instruction manual is attached. Figure 1 The warehouse 1 in the figure only shows a part of it, not the actual warehouse 1. The figure only shows the bottom of the warehouse 1. Figure 2 This is the cutting angle of one side of the warehouse body 1, the instruction manual is attached Figure 3 The silo 1 is hidden, and the length of the support tube 2 is shortened to prevent the overall viewing of the drawings from being affected. Figure 4 This is a top view of the support tube 2. Figure 3 The subsequent support tubes 2 were shortened because Figure 1 The middle support tube 2 is very long, which affects the viewing angle, so Figure 3 The length of the support tube 2 was shortened at the beginning, and the instruction manual was attached. Figure 5 The support tube 2 was cut in the middle, and the instructions are attached. Figure 6 Attached to the instruction manual Figure 5 The local diagram in the manual is attached Figure 5 There are corresponding dividing lines in the manual. Figure 8 Another perspective cut of the support tube 2 is attached to the instruction manual. Figure 5 To cut towards the middle, the instructions are attached. Figure 8 To cut facing right, refer to the Figure 3The support tube 2 of the present scheme is fixedly provided with one side of the warehouse body 1, and the support tube 2 has two functions. The first is to support the down-pressure tube 3 below, and the second is to serve as a gas transmission pipeline. One side of the support tube 2 needs to be externally connected to an air outlet device so that the support tube 2 can enter the gas. The down-pressure tube 3 is slidably provided on the lower surface of the support tube 2, and there is a sealed sliding between the down-pressure tube 3 and the support tube 2 (there is a No. 1 spring 5 between the two, and the No. 1 spring 5 is used to reset the down-pressure tube 3. Under the action of the gas, the down-pressure tube 3 will move downward, and after the gas is discharged, it will be reset under the pull of the No. 1 spring 5). A slideway corresponding to the down-pressure tube 3 is provided inside the support tube 2, so that the down-pressure tube 3 can slide vertically downward, and a The release port 30 allows the gas to reach the inside of the pressure-down pipe 3 from the support pipe 2, because the gas entering the support pipe 2 cannot enter from the top of the pressure-down pipe 3, but can only enter from the top port 31 of the pressure-down pipe 3. That is, when the gas continues to enter the support pipe 2, the gas cannot be discharged, resulting in a continuous increase in the internal pressure, which controls the pressure-down pipe 3 to move downward, so as to achieve the effect of adding gas to make the pressure-down frame 4 move downward. This scheme utilizes the sealing property of the gas to achieve downward pressure, until the pressure-down pipe 3 moves to the position of the release port 30, the gas will instantly pass through the top port 31 from the release port 30 and reach the bottom port 32 (because the bottom of the pressure-down pipe 3 cannot discharge the gas either, although the insertion rod 18 is set to slide At the bottom of the pressure tube 3, but the two are sealed), together with the bottom opening 32, it is arranged at a 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 separated, so a sealing period is formed between the bottom of the pressure tube 3 and the pressure tube 3, and this sealing interval is finally transported to the bottom block 34, the bottom block 34 is integrally arranged at the bottom of the pressure frame 4, at the rotation center of the pressure frame 4, corresponding to the rotatable setting of the insertion rod 18, the gas enters the bottom block 34, and reaches the ejection channel 11, achieving the effect of gas ejection, because the rotating knife 10 is rotatably arranged on the bottom block 34, and the middle part of the rotating knife 10 is a hollow tube, the hollow tube Corresponding through holes are provided on both sides so that the gas can enter the interior of the ejection channel 11, and the middle part of the rotating knife 10 and the bottom block 34 are sealed and rotated to ensure that the gas can eventually reach the ejection channel 11. In summary, the gas first compresses the pressure tube 3 to move downward, and accumulates the gas. The pressure formed by the gas drives the pressure tube 3 to move downward little by little until it moves to the vicinity of the release port 30, from the release port 30 to the top port 31 to the bottom port 32 to the corresponding port 33 to the bottom block 34, and finally reaches the ejection channel 11 to achieve the effect of releasing the gas, and the gas has an impact force in the process of releasing the gas. This scheme relies on the pressure tube 3 to be able to move downward and reset to design a pressure frame 4, and the pressure frame 4 is rotatably arranged at the bottom of the pressure tube 3.Most of the structures of this solution are designed based on the movable distance of the lower pressure tube 3. First, the rotating circle 22 of this solution is introduced. The rotating circle 22 is rotatably arranged above the lower pressure frame 4, and has an anti-detachment structure and cannot be separated from the lower pressure frame 4, and the two can rotate. This solution relies on the rotation of the rotating circle 22 to drive the lower pressure frame 4 to adjust its position. The outer surface of the rotating circle 22 is provided with a rotating groove 23, and the rotating groove 23 is an arc-shaped oblique groove, and the round rod 24 is just overlapped on the rotating groove 23. When the lower pressure frame 4 moves downward, the rotating circle 22 does not rotate at this time. The rotating circle 22 only holds the round rod 24 to move downward. When it is about to move to the bottom, since there is a compression spring 25 on one side of the round rod 24, it is noted that this compression spring 25 is not connected to the round rod 24. The bottom end of this compression spring 25 is fixedly arranged on the support tube 2, because it extends on one side of the support tube 2 The bottom of the compression spring 25 is arranged on the support tube 2, and the top waits for the round rod 24 to move downward for extrusion, that is, the above description waits for the lower pressure tube 3 to reach the bottom, and the compression spring 25 is compressed, so that the rotating circle 22 rotates, and the rotation of the rotating circle 22 drives the lower pressure frame 4 to rotate (because a cross block 26 is provided on the edge of the rotating circle 22 for sliding, and one side of the cross block 26 has a small reset spring, and the other side of the cross block 26 is overlapped on the lower pressure frame 4 and forms a one-way rotation with the lower pressure frame 4, that is, when the lower pressure tube 3 moves downward, it drives the lower pressure frame 4 to rotate, and when the lower pressure frame 4 resets upward, the cross block 26 slips on the lower pressure frame 4, achieving the effect of being unable to drive, and the spring on one side of the cross block 26 has the effect of contacting the lower pressure frame 4, as shown in the instruction manual, Figure 6 As shown, the summary is that the lower pressing frame 4 will rotate and adjust the position at the tail end of the downward movement, and the lower pressing frame 4 will remain unchanged when moving upward (in order to make the lower pressing frame 4 of this scheme stable, the lower pressing frame 4 is attached to the specification). Figure 6 A raised hemispherical block is arranged on the left side of the reference numeral 3, and the hemispherical block is just plugged into the bottom of the lower pressure frame 4, that is, a circular groove corresponding to the hemispherical block is opened at the bottom of the lower pressure frame 4, and the number of the circular grooves is multiple, and the array is arranged at the bottom of the lower pressure frame 4, and the angles of two adjacent ones correspond to the left and right span angles of the rotating groove 23, so that the lower pressure frame 4 can rotate and stop stably). In summary, this paragraph is that the lower pressure pipe 3 can move downward to reset, and in the process of moving downward, the lower 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 solution. The core structure of this solution is a cutting knife 6, which is rotatably arranged on the edge of the lower pressure frame 4, and has a No. 7 spring on one side. The No. 7 spring is a torsion spring and can be rotated and reset. As shown in all the drawings of this solution, the No. 7 spring is in a torsion state, that is, a power storage state, as shown in the attached manual. Figure 6 As shown, once released, it rotates toward the left side. Since a slidable block 9 is provided in the middle of the cutting knife 6, this block 9 is the reason why the cutting knife 6 is stable and immovable. There is a ratchet in the middle of the cutting knife 6, and the ratchet and the block 9 form a one-way mechanism. If you want to release, you need to move the block 9 upward. In the process of the downward movement of the lower pressure frame 4, this solution can make the release bar 8 immovable first, and then move with the lower pressure frame 4, because the release bar 8 is slidably arranged on the lower surface of the buffer ring 12, and there is a control spring 13 between the two, and the control spring 13 is difficult to compress. Therefore, when the lower pressure frame 4 moves downward, the release bar 8 is not moved at the first time, and the release bar 8 will move upward relative to the lower pressure frame 4 (because the release bar 8 does not move and the lower pressure frame 4 moves downward), the release bar 8 will move upward against the block 9, so as to achieve the effect of releasing the cutting knife 6, and the cutting knife 6 will rotate under the elastic force of the second spring 7 to contact the edge of the warehouse body 1, cutting the solid accumulated on the edge of the warehouse body 1 The cutting blade 6 has a cutting effect and also has an effect of hitting the surface of the bin body 1, so that the cut solid residue is easy to fall off, that is, the cutting blade 6 will be released in the initial stage of the downward movement. Since the release bar 8 has a limited sliding distance on the lower pressure frame 4, the control spring 13 will be compressed after the cutting blade 6 is released, and the cutting blade 6 moves downward (a small spring is provided above the block 9 for reset). When the lower pressure frame 4 moves downward and returns, the control spring 13 can be restored first (the release bar 8 remains unchanged on the lower pressure frame 4 during the recovery process, and the release bar 8 is moved downward relative to the lower pressure frame 4 when it reaches the top. The above introduction is equivalent to the upward movement of the lower pressure frame 4, and the introduction at this time is equivalent to downward movement. The downward movement can make the side bar 21 on one side of the release bar 8 press the cutting blade 6 to reset and rotate, because there is an integrally arranged bar on one side of the middle part of the cutting blade 6, which corresponds to the side bar 21. Figure 6 That is, on one side of the middle of the cutting blade 6, this strip can be extended to facilitate the downward push of the side strip 21, and the downward push of the side strip 21 corresponds to the appendix of the manual. Figure 6The position of the cutting knife 6, that is, the cutting knife 6 is rotated and reset to its original state, and the card block 9 is also pushed by the surface above the side strip 21. The middle parts of the two are staggered, which does not affect the normal pushing movement. Because one side of the card block 9 extends to the right side and extends downward, the side strip 21 is pushed and extended downward, so that the card block 9 moves upward, which is the role of the side strip 21. The card block 9 can be pushed upward, and the cutting knife 6 can be reset downward). In summary, the cutting knife 6 releases the cutting first when it moves downward, and then resets the tail end that moves upward. The buffer ring 12 is rotatably arranged on the support tube 2, and the support tube 2 only guarantees the position of the buffer ring 12. Since the lower pressing frame 4 can rotate, the buffer ring 12 is arranged to be rotatable on the support tube 2 to prevent affecting the rotation of the lower pressing frame 4. An extrusion frame 27 is arranged below the cutting knife 6. The extrusion frame 27 is slidably arranged on the edge of the lower pressing frame 4. The extrusion frame 27 is driven downward by the release of the cutting knife 6, because a triangle is extended from the edge of the cutting knife 6, and this triangle is against the top of the extrusion frame 27. As shown in the attached manual Figure 3 As shown, the extrusion frame 27 moves downward, and the rotating knife 10 is just below the extrusion frame 27. A clamping plate 28 is slidably arranged on the surface of the extrusion frame 27. The clamping plate 28 moves downward just to scrape off the dust on the surface of the rotating knife 10. A No. 5 spring 29 is arranged between the extrusion frame 27 and the lower pressing frame 4 for resetting. A transverse spring is also arranged between the clamping plate 28 and the extrusion frame 27. This transverse spring enables the clamping plate 28 to be extruded and reset transversely on the extrusion frame 27. Because the rotating knife 10 can rotate, the setting of this transverse spring is also to prevent the rotation of the rotating knife 10 from being affected. In fact, the cross block 26 has an end distance from the top of the rotating knife 10. The specification of this scheme is attached Figure 3 The displayed distance is very short, but it is not. Instead, it has a distance at one end. Finally, the rotary knife 10 of this scheme is introduced. The rotary knife 10 of this scheme can rotate ninety degrees. The rotary knife 10 does not change its angle when moving downward. It will only rotate ninety degrees when it reaches the bottom to make it flat. Because the middle part of the rotary knife 10 is a gear, this gear is engaged with the insertion rod 18, that is, the insertion rod 18 moves up and down to adjust the position of the rotary knife 10. When the lower pressure frame 4 moves downward, the top of the insertion rod 18 will drive the driving bar 15 to move downward. Since the driving bar 15 has a sliding distance limit, it cannot continue to drive when it reaches a certain distance. At this time, the rotating block 16 will be twisted. One side of the rotating block 16 has a No. 4 spring 20, and the No. 4 spring 20 is a torsion spring. The elastic force of the No. 4 spring 20 is greater than (a No. 6 spring is arranged between the driving bar 15 and the internal bar 14. The No. 6 spring is not standardized in the figure, but is only shown in the figure, as shown in the attached manual Figure 8As shown, the elastic force of the No. 6 spring makes it possible to compress the No. 6 spring at the beginning under the drive of the insertion rod 18, until the sliding distance between the internal strip 14 and the driving strip 15 cannot slide, then the No. 4 spring 20 will be twisted to achieve the effect of the top of the insertion rod 18 being separated from the inclined block 17, and then the insertion rod 18 will be reset under the action of the No. 3 spring 19, that is, the rotary knife 10 rotates, and the No. 3 spring 19 is attached to the instruction manual Figure 8 In summary, the rotary knife 10 rotates at the tail end of the downward movement of the lower pressing frame 4 (releasing the insertion rod 18, the insertion rod 18 moves downward on the bottom block 34 to rotate the rotary knife 10), and when the lower pressing frame 4 moves upward, the cutting knife 6 moves horizontally upward all the time, and finally the insertion rod 18 reaches the top of the inclined block 17 again. 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 downward under the action of the No. 3 spring 19, that is, at this time the rotating knife 10 is horizontal, and it is shown as vertical in the accompanying drawings. For the sake of easy understanding, this scheme makes this state static, that is, the No. 3 spring 19 needs to pull the insertion rod 18 to move downward, and the rotating knife 10 is in a horizontal state, not a vertical state as shown in the figure, because the extrusion plate and the clamping plate 28 are to be engaged, the elastic force of the No. 3 spring 19 is less than the elastic force of the No. 6 spring, and the rotating knife 10 is not released when the No. 3 spring 19 is stretched, which corresponds to the horizontal rotating knife 10. One side of the inclined block 17 is an inclined surface corresponding to the upper cone of the insertion rod 18 The design is convenient for the inclined block 17 to squeeze. One side of the inclined block 17 has a small spring reset. In order to make the present scheme stable in use, a driving gear 35 is arranged inside the support rod. The driving gear 35 can control the downward movement of the lower pressure tube 3 and can replace the gas drive, which is more stable. The driving gear 35 is only an alternative of the present scheme. One side of the driving gear 35 needs to be installed with a motor to drive the rotation. The internal strip 14 and the lower pressure tube 3 are sealed and slidable. In summary, the effect of the present scheme is that the cutting knife 6 of the present scheme can be released during the downward movement of the lower pressure frame 4 to achieve the effect of cutting solid agglomerates. At the same time, it can form an impact effect, so that the agglomerates are easy to fall off. At the same time, the overall position of the lower pressure frame 4 can be adjusted, and the cutting knife 6 can be retracted when moving upward, and the rotating knife 10 When moving downward, it can cut vertically downward, and the dust accumulated at the bottom of the bin body 1 can rotate horizontally during the upward process, and a part of the dust can be driven to the top to achieve the effect of dredging, and during the rotation process, the position of the ejection channel 11 can be adjusted from the initial vertical ejection to the lateral ejection on both sides, corresponding to the fixed agglomeration position encountered for cutting, so as to facilitate the solid agglomerates to be blown off from the side wall of the bin body 1, and a lower pressure frame 4 is rotatably arranged on the surface of the lower pressure pipe 3, a No. 1 spring 5 is arranged between the support pipe 2 and the lower pressure pipe 3, and a folding mechanism is arranged on the edge of the lower pressure frame 4, the folding mechanism includes a cutting knife 6, a No. 2 spring 7 and a release strip 8, the cutting knife 6 is rotatably arranged on the edge of the lower pressure frame 4, the release strip 8 is slidably arranged on one side of the lower pressure frame 4, and the cutting knife A card block 9 is overlapped in the middle of 6, and the card block 9 is slidably arranged on the edge of the lower pressure frame 4.
