Description

Technical Field

[0001] The invention relates to the technical field of ash conveying flues, and in particular to a comprehensive technology for extending the life, reducing resistance, energy saving and consumption reduction of various systems of a pilot type smoke collecting and conveying flue. Background Art

[0002] Thermal power generation uses the heat energy generated by the combustion of combustibles and converts it into electrical energy through a power generation device. In thermal power generation technology, a large amount of dust will be generated when the fuel is burned. The existing pneumatic ash conveying technology can be used to drive the dust and smoke in the pipe body to circulate through gas, so that the dust and smoke are brought to designated equipment. When passing through the smoke collection and transportation flue, filters need to be set up layer by layer. Since the filters are difficult to replace inside the pipeline, and the filters need to be cleaned regularly at regular intervals, and the channel needs to be stopped, a certain amount of resources are wasted, and the surface of the filters cannot be cleaned while the flue is in use.

[0003] In view of the above, we provide comprehensive technologies for extending the life, reducing resistance, energy saving and consumption reduction of each system of pilot smoke collection and transportation ducts to solve the above problems. Summary of the invention

[0004] In view of the above situation, the present invention provides a comprehensive technology for extending the life, reducing resistance, saving energy and reducing consumption of each system of the pilot-type smoke collecting and transporting flue. The clamping bar arranged on the pipeline can move up and down under the drive of the lifting bar. During the upward movement, the filter net can be lifted up, so that the dust moves to both sides, making it convenient for the cleaning rods on both sides to transport the dust to the outside.

[0005] The comprehensive technology for extending the life, reducing resistance, saving energy and reducing consumption of each system of a pilot-type smoke and dust collecting and conveying flue comprises a pipeline, wherein a filter screen is arranged inside the pipeline, a clamping bar is slidably arranged on the surface of the filter screen, a lifting bar is rotatably arranged on the lower surface of the clamping bar, a linkage mechanism is arranged on one side of the lifting bar, a deflection mechanism is arranged on the top of the clamping bar, the deflection mechanism comprises a deflection bar, a guide groove, an air outlet, a movable bar and a rotating bar, the air outlet is arranged at the top of the clamping bar, the deflection bar is rotatably arranged in the middle of the movable bar, the guide groove is arranged at the bottom of the movable bar, the rotating bar is rotatably arranged below the clamping bar, the lifting bar is slidably arranged inside the pipeline, an extension bar is integrally arranged on one side of the lifting bar, a lower pressing bar is contacted with the top of the extension bar, the lower pressing bar is slidably arranged on one side of the clamping bar, the top of the lower pressing bar is overlapped with a rotating bar, and a magnet is arranged on the surface of the rotating bar.

[0006] The above technical solution has the following beneficial effects:

[0007] The clamping bar designed in this scheme can move up and down under the drive of the lifting bar. During the upward movement, the filter screen can be lifted up, so that the dust moves to both sides, which is convenient for the cleaning rods on both sides to transport the dust to the outside. During the upward movement, the clamping bar can deviate to the left and right, and the left and right deviation can make the filter screen slide on the clamping bar. During the sliding process, air can be blown out to the bottom of the filter screen to blow out the dust, and the wind direction reaches one side of the deviation bar through the guide groove, acting on the side of the guide bar that scrapes the dust. The deviation bar can deviate and scrape the dust under the action of the rotating bar magnet, and it can also generate vibration during the scraping process, so as to achieve the effect of rapid dust dropping.

DETAILED DESCRIPTION

[0018] 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 9 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.

[0019] This embodiment provides a comprehensive technology for extending the life of each system of the pilot smoke collection and transportation duct, reducing resistance, energy saving and consumption reduction, as shown in the attached Figure 1-9 As shown in the instruction manual, Figure 1 This is the overall three-dimensional diagram of this scheme. The upper and lower ends of the pipe 1 are taken from a section of the overall flue and do not exist independently. Figure 2 This is a cut view of the middle of the pipe 1, from which it can be seen that the filter screen 2 is distributed in this solution. Figure 3 The instruction manual is attached Figure 2 The middle plane is the cutting plane, and the attached drawings are attached to the manual. Figure 2 And the instruction manual Figure 3 These are cutting diagrams from different angles. The cutting angles of the two diagrams are perpendicular to each other. Figure 4 At the beginning, the pipe 1 is not displayed, so many structures look like they are suspended in the air, but in fact they are not all on the pipe 1. Figure 4 Since the internal structure is horizontally long and thin, it is not convenient to read the attached drawings, so wavy lines are used to reduce the elongated distance and facilitate viewing of the structure. Figure 5 This is a cutting diagram of one side of the clamping strip 3, attached to the instruction manual Figure 6 And the instruction manual Figure 4 It's just a difference in perspective. Figure 8 The figure is a partial cutaway view of the swing bar 25. A filter screen 2 is arranged inside the pipe 1. However, the filter screen 2 of this solution is not a rigid screen, but a flexible screen that can be deformed. A clamping strip 3 is sleeved in the middle of the filter screen 2. The middle of the clamping strip 3 just passes through the filter screen 2. Figure 5As shown, between the deflection strip 5 and the air outlet 7 is the filter screen 2. Since the surface of the filter screen 2 is provided with densely packed filter holes, in order to make the drawings clear, this solution only symbolically draws a part of the filter holes. Under normal operation, the filter screen 2, as shown in the attached manual Figure 2 As shown, it is in a low-lying state. The purpose of this scheme is to move the clamping strip 3 upward so that the filter screen 2 changes from a low-lying state to an upward protrusion. When the filter screen 2 is protruding, the filtered dust will be dispersed to both sides, and the two sides are correspondingly provided with ash discharge rods. The shape of the ash discharge rod is a circle and one side is flat. The ash discharge rod relies on the setting of one side of the flat surface to rotate the dust on one side to the outside of the pipe 1, and can seal both sides of the pipe 1. A motor is installed on one side of the ash discharge rod, and the motor controls the ash discharge rod to rotate automatically. This scheme does not introduce the prior art in detail. For example, the driving wheel 28 is set on one side of the middle wheel 14, and it is not a suspended setting that requires the installation of a corresponding motor. The motor drives the driving wheel 28 to rotate. Because the motor is installed, A corresponding support frame needs to be set up, which supports the motor, and the driving wheel 28 is installed on the shaft of the motor, so the driving wheel 28 also has a certain support, so that the driving wheel 28 can drive the middle wheel 14 to rotate. The middle wheel 14, the lifting gear 12 and the forked wheel 15 of this scheme are all rotatably set on one side of the pipeline 1, and the middle gear is in the middle between the three. The outer side of the middle gear can overlap the dislocation bar 18, and the inner side can overlap the lifting rack 13. The middle gear adopts an outer groove 16 and an inner groove 17 correspondingly set on the outer and inner sides. The outer groove 16 overlaps the dislocation bar 18, and the inner groove 17 overlaps the lifting rack 13. The outer groove 16 is introduced first. The outer groove 16 has three arcs. The centers of the three arcs coincide with the center of the middle wheel 14, and the radius decreases successively, so they are named large, medium and small. The instruction manual is attached Figure 4When the middle wheel 14 rotates slowly, the middle is responsible for overlapping the dislocation strip 18, which is large on the left and small on the right. In this way, when the middle wheel 14 rotates slowly, the large, medium and small will maintain the position of the dislocation strip 18, and the large, medium and small are connected in sequence, so that the three groups can be switched, and there is a slope between the two to connect to another arc, that is, it can be understood that the range of the arc is 120 degrees (the connection between the two is negligible), and the shape of the inner groove 17 is roughly a triangle, and at this time the lifting rack 13 overlaps the midpoint of the triangle side, which is the position closest to the center of the middle wheel 14, and as the middle wheel 14 rotates, the lifting gear 12 will move downward (the lifting gear 12 and the dislocation strip 18 are limited by the pipe 1 to slide vertically, and a corresponding limiting structure is provided on one side of the pipe 1), and the triangle has three periods, corresponding to the large, medium and small arcs, and the three circles The arc covers the period of the triangle, so that the middle wheel 14 rotates to control the lifting rack 13 to move downward. The lifting rack 13 moves downward and controls the lifting gear 12 to rotate at the same time. The outer side of the lifting gear 12 meshes with the lifting rack 13 and the inner side of the lifting bar 4 (the lifting bar 4 is provided with a corresponding tooth block, and this scheme only shows one side, which is actually a mirror design), so that the lifting bar 4 moves upward, and the upper surface of the lifting bar 4 is provided with a clamping bar 3, and the middle wheel 14 can drive the dislocation bar 18 to move up and down, so that the fork wheel 15 can be rotated and positioned accordingly, that is, fixed in one position. Because the large, medium and small have three arcs, the fork wheel 15 can make the through slot 19 on one side perform three states of vertical left deflection and right deflection. In this way, the entry column 20 has three paths when moving upward. Figure 4When it moves upward, the entry column 20 will enter the through slot 19, or move vertically upward, that is, the deviation bar will still move upward, but at this time the fork wheel 15 rotates a certain angle (left or right is fine, at this time the through slot 19 is displaced to other positions. And due to the large, medium and small arc characteristics, the fork wheel 15 does not move), and at this time the vertical upward movement will hit one side of the fork wheel 15 (that is, on the inclined surface outside the entry slot), which will cause the deflection bar 5 to rotate. During the rotation of the deflection bar 5, the filter screen 2 will slide on the surface of the clamping bar 3 (the filter screen 2 is long enough and has a certain elasticity). This solution uses this sliding to allow the deviation bar to clean the surface of the filter screen 2. In summary, the middle wheel 14 controls the three fixed forms of the fork wheel 15, and at the same time controls the lifting bar 4 to drive the clamping bar 3 to move upward, so as to achieve The three-form deflection on both sides of the middle part, the rotation spring 24 is a torsion spring and is also the only spring with a label in this scheme (the rest of the springs will be introduced in the text). The springs in this scheme are all in the original length state (the torsion spring is in the untwisted state), because the rotation spring 24 can make the clamping bar 3 rotate and reset, and can be rotated and reset to the vertical state. A deviation bar is designed based on the deviation of the clamping bar 3. The deviation bar is rotatably set on the lower surface of the movable bar 8, and the movable bar 8 is slidably set on the top of the clamping bar 3, and there is a sliding gap between the two. In order to make the movable bar 8 have a certain fault tolerance rate, a spring is set on this sliding gap so that the movable bar 8 has a certain fault tolerance rate. Since it is difficult to control the deflection bar 5 to rotate when the clamping bar 3 is deflected, this scheme uses a magnet to control the rotation of the deflection bar 5, as shown in the attached manual Figure 5 As shown, a magnet is arranged above the rotating bar 9. Above the number 9 is a circular magnet, and a corresponding magnet (on the side) is arranged on one side of the deviation bar. The two magnets are of the same polarity, and the effect of the deviation bar is mirrored. Therefore, when one side of the rotating bar 9 approaches the deviation bar, the deviation bar will be controlled to deviate. The rotating bar 9 is close to the lower pressure bar 11 of the present solution. The lower pressure bar 11 is slidably arranged on one side of the clamping bar 3, and a spring is arranged between the lower pressure bar 11 and the clamping bar 3, as shown in the attached manual. Figure 5As shown, the spring is under the label 11. In this solution, the spring is always in an extruded state, that is, the lower pressing bar 11 is continuously moved downward (in the absence of obstacles). The upper part of the lower pressing bar 11 has a notch, which is overlapped at the bottom of the rotating bar 9. The lower pressing bar 11 can make the rotating bar 9 rotate in one direction when it rises, and can make the rotating bar 9 rotate in the opposite direction when it falls. The rise or fall of the lower pressing bar 11 depends on the extension bar 10 at the bottom. The upper side of the extension bar 10 has an oblique bar. When the clamping bar 3 rotates in two directions, the lower pressing bar 11 will rotate and squeeze (squeezing means that the lower pressing bar 11 continues to squeeze the spring) or rotate and press (pressing means that the inclined surface moves away from the lower pressing bar 11), so that the rotation direction of the clamping bar 3 controls the up and down movement of the lower pressing bar 11, and the up and down movement of the lower pressing bar 11 controls the left and right swing of the rotating bar 9, and finally controls the left and right deflection of the deflection bar 5 (the magnets repel each other). The final result is that when the clamping bar 3 rotates to the left, the deflection bar 5 The deviation strip (the rotation center of the deviation strip is at the top) also deviates to the left, so that the sharp end contacts the upper surface of the filter 2, achieving the effect of scraping dust. When the deviation strip deviates, it also has the effect of changing the wind direction. The air outlet 7 supplies gas through the external pipe 31, and the external pipe 31 needs to be externally connected to an external fan. The fan belongs to the prior art and is not introduced in detail. The external pipe 31 discharges air to the air outlet 7, and the air outlet discharges air toward the top. There is a filter 2 between the air outlet 7 and the deviation strip, but the surface of the filter 2 is also introduced with dense small holes, so that the wind will pass through the filter 2 to achieve the effect of cleaning the filter 2, and the blowing position is facing the side surface of the deviation strip (the deviation strip has been rotated). At this time, the deviation strip acts as a guiding surface. The wind reaches the deviation strip and is guided to the other side of the deviation strip through the guide groove 6 (the other side of the deviation strip is being cleaned), that is, the wind is guided to the cleaning action point to achieve the effect of scraping dust. This is the function of the deviation strip, and the surface of the deviation strip needs to be provided with small raised blocks to prevent blocking the guide groove 6.

[0020] In order to cooperate with the deviation strip to scrape the dust and facilitate shedding, a striking strip 21 is slidably arranged on both sides of the clamping strip 3. The principle of the striking strip 21 is to pull the line down to accumulate force and hit the top of the clamping strip 3 to form vibration. The vibration can not only vibrate the filter screen 2 but also vibrate the deviation strip. Here is how the striking strip 21 accumulates force. The striking strip 21 is slidably arranged on one side of the clamping strip 3, and there is also a spring at the bottom, as shown in the attached manual. Figure 5As shown, below the reference numeral 21, a curved strip 22 is integrally provided on one side of the striking strip 21. The curved strip 22 is an arc and has an inclined surface on one side. This allows the striking strip 21 to be controlled to move downward under the drive of the entry block 23 when the clamping strip 3 rotates. Because the position of the entry block 23 does not move, and the deviation strip rotates, the rotation causes the bottom curved strip 22 to be pressed downward, that is, the striking strip 21 is pressed downward (due to the limited angle of the curved strip 22 and the rotation angle of the clamping strip 3 The degree is large, so pressing down a certain angle will make the entry block 23 separate from the arc strip 22), and pressing down the striking bar 21 and then releasing it is equivalent to accumulating force, and the striking position is at the bottom of the deflection bar 5, and the surface of the entry block 23 has a spring, so that one side of the entry block 23 can re-enter the upper part of the arc block of the block 23 when the deflection bar is vertical (one side of the entry block 23 is spherical, and the bottom of the arc strip 22 is an inclined surface, so it can re-enter), and the same is true for the matching bar 26, which is slidably arranged on the lifting The lever 26 is in the state of being moved downwardly, and the spring 27 is provided on the lever 26 to prevent the lever 26 from sliding downwardly. Figure 7 The left mark of label 25 points to that the fixed bar 27 can also make the swing bar 25 accumulate power and rotate and swing after the lifting block moves upward. The principle is similar to the above. One side of the swing bar 25 also has a torsion spring, the left side of label 31, and the swing bar 25 can discharge air to achieve the effect of rotating air discharge, so as to achieve the effect of guiding dust to both sides. In order to enable the swing bar 25 to switch the air discharge up and down, a hidden rod 33 is designed. The hidden rod 33 is sealingly slidably arranged on the connecting pipe 32, but when the lifting rod moves upward, there is no fixed bar 27 at the bottom to push it, and the hidden rod 33 will move downward under the action of the spring. A spring is arranged between the hidden rod 33 and the connecting pipe 32. The spring is in the attachment of the instruction manual. Figure 7The lifting rod 33 is squeezed in the middle, so the upward movement of the lifting rod will make the hidden rod 33 move downward. The top of the hidden rod 33 has one side against the swing valve 29, so the swing valve 29 will rotate accordingly. The rotation of the swing valve 29 will switch the rotating channel 30 from the bottom to the top for exhaust. Please see the attached manual Figure 8 and 9 ,exist Fig. 9In the figure, the swing valve 29 rotates counterclockwise by a certain angle, and a torsion spring is arranged on one side of the swing valve 29, which will automatically twist and reset without pushing.
