Description

Technical Field

[0001] The present invention relates to the technical field of boiler headers, and in particular to an inclined header for a reciprocating grate steam boiler. Background Art

[0002] Reciprocating grate steam boiler is a steam boiler that uses reciprocating grate as combustion device. It is mainly used to convert the heat energy generated by the combustion of fuels such as coal and biomass into high-temperature and high-pressure steam, which is then used in power generation, heating, industrial production and other fields.

[0003] The existing steam boiler is usually provided with a header for collecting and distributing water, but the existing lower header is usually not provided with a filtering mechanism. When the boiler water pipe passes water to the lower header, it is easy to cause the water source input into the lower header to contain organic impurity lumps or metal flake impurities due to the influence of the external water source or pipeline corrosion. If these impurities are not filtered and directly input into the header, it may cause the pipes in the header to be blocked, affecting the use effect. In addition, when in use, the lower header is usually also arranged on both sides of the grate to contact the coal layer burning on the grate, absorb part of the heat through the heat conduction layer, adjust the temperature of the fuel layer, thereby effectively preventing the occurrence of coking. The temperature of the heat conduction layer of the lower header contacting the grate will be much higher than that of other places in the header, and the existing lower header is usually not provided with a mechanism for strengthening the cooling of the heat conduction layer of the lower header. If the heat conduction layer is not strengthened and cooled, the temperature of the heat conduction layer cannot be obtained. The effective decline may cause the fuel layer to coke in the long run. Since the header is arranged inside the boiler and the interior of the header is relatively small, chemical cleaning methods are usually adopted when cleaning, and chemical agents are used to dissolve the dirt inside it. However, the existing header usually does not have an automatic cleaning mechanism. When in use, it is still necessary to manually sprinkle chemical agents, which is time-consuming and labor-intensive. In addition, the domestic reciprocating grate boilers currently use horizontal headers, which are either placed on both sides below the grate surface or above the grate surface. The horizontal headers are placed on both sides below the grate, and the water-cooled wall tubes on both sides need to cover the grate. The part exceeding the grate surface cannot play the role of radiation heating, which wastes steel. At the same time, the sealing part is prone to air leakage and difficult to handle, and it is inconvenient to repair. If the horizontal header is placed above the grate surface, there will be some vacancies between the water-cooled wall tubes on both sides and the grate surface, the heat loss will increase, and the heating surface will be reduced. Furnace walls need to be built at the vacant positions, which increases the cost of regular furnace wall maintenance. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the setting of filter plates and other mechanisms, when in use, the filter plates will filter the water input into the lower header to prevent impurities in the water from affecting the use effect of the lower header. When the filter plates filter impurities, the bristles will also rotate to clean the surface of the filter plates to prevent the accumulation of more impurities on the surface of the filter plates, causing the filter plates to become blocked and affecting the water flow effect of the lower header.

[0018] 2. Through the setting of the guide plate and other mechanisms, when the lower header needs to exchange heat and cool the coal seam during use, the guide plate will deflect toward the heat-conducting layer in contact with the coal seam. At this time, the cooling water entering the lower header will focus on impacting the heat-conducting layer under the guidance of the guide plate. When the cold water impacts the heat-conducting layer, it can take away the heat of the heat-conducting layer more quickly, thereby improving the heat exchange efficiency, ensuring the heat exchange effect of the entire lower header on the coal seam, and preventing the coal seam from coking. While the header head passes water into the lower header, the stirring plate will also stir the cooling water through the bubble-making plate to create a large number of bubbles. The disturbance of the bubbles can reduce the thermal resistance between the heat-conducting layer and the cooling water, making it easier for the heat conducted by the heat-conducting layer to be transferred to the cooling water, thereby improving the heat exchange efficiency of the entire lower header.

[0019] 3. Through the setting of the liquid sprinkling chamber and other mechanisms, when it is necessary to clean the lower header box, the liquid sprinkling chamber will automatically sprinkle chemicals out under the action of magnetic force, so that the chemicals and water are fully mixed to dissolve the dirt in the lower header box. The whole cleaning process is simpler and faster than manually sprinkling chemicals.

[0020] 4. By obliquely attaching the lower header to the grate, the radiation heating area of ​​the main furnace is not affected and steel is not wasted. In addition, the service life of the water-cooled fireplace wall is much longer than that of the brick furnace wall, avoiding the maintenance cost of the furnace wall.

The interior of the dirt storage box 10 is connected to a water pipe 11. The end of the water pipe 11 away from the dirt storage box 10 is connected to the interior of the collecting head 6.

[0041] The liquid throwing cleaning mechanism is arranged on the side of the filtering mechanism and is used to clean the inside of the grate 3. The liquid throwing cleaning mechanism includes a stirring plate 31 fixedly connected to both sides of the driving shaft 20, and a mounting protrusion 34 is fixedly connected to the outer wall of the stirring plate 31, and a baffle 33 is slidably connected to the inner wall of the stirring plate 31. A pressing spring 35 is arranged between the baffle 33 and the mounting protrusion 34, and an adsorption magnet 37 is fixedly connected to the end of the baffle 33. A bubble making plate 36 is fixedly connected to the inside of the stirring plate 31, and a pushing magnet 32 ​​is slidably connected to the outer wall of the stirring plate 31. A damping spring rod 44 is fixedly connected to the outer wall of the pushing magnet 32, and the other end of the damping spring rod 44 is fixedly connected to the outer wall of the stirring plate 31. A fixed spring 35 is fixedly connected to the outer wall of the filter plate 12. The fixed member 23 and the fixing member 23 have a covering ring 22 fixedly connected to their outer walls, the covering ring 22 is connected to a material guide tube 21, the covering ring 22 is slidably connected to the driving shaft 20, a plurality of through holes 48 are provided in the driving shaft 20, a guide groove 38 is provided in the driving shaft 20, the guide groove 38 and the plurality of through holes 48 are connected to each other, a bottom cavity 39 is provided at the end of the driving shaft 20, the guide groove 38 is connected to the inside of the bottom cavity 39, both sides of the bottom cavity 39 are connected to a liquid sprinkling cavity 40, a liquid throwing port 42 is provided at the end of the liquid sprinkling cavity 40, the inside of the liquid throwing port 42 is blocked by a closing plug 41, a connecting rod 43 is fixedly connected to the outer wall of the closing plug 41, and one end of the connecting rod 43 away from the closing plug 41 is fixedly connected to the outer wall of the baffle 33.

[0042] In the present embodiment, when in use, the operator can firstly introduce cooling water into the water inlet 8 through an external water pipe. After the cooling water enters the collecting head 6, it will first be filtered by the filter plate 12, and the impurities contained in the water will be filtered and retained on the surface of the filter plate 12. While the filter plate 12 is filtering the water, the operator can turn on the dual-axis motor 18 to drive the transmission shaft 16 and the driving shaft 20 to rotate respectively. When the transmission shaft 16 rotates, the brush 17 will be driven by the cleaning rod 15 to clean the surface of the filter plate 12, and the impurities on the surface of the filter plate 12 will be cleaned to avoid more impurities adhering to the surface of the filter plate 12, which will affect the filtering effect of the filter plate 12. When the water filtered by the filter plate 12, it will come to the back of the filter plate 12 and be stirred by the rotating stirring plate 31. When stirring the water, the bubble making plate 36 on the stirring plate 31 will make bubbles in the filtered water.

[0043] While the stirring plate 31 rotates to stir the water, since the push cylinder 27 is arranged on the side of the lower header 2 that contacts the coal seam, namely, the heat-conducting layer, the temperature of the heat-conducting layer is very high, and the high temperature conducted by the heat-conducting layer will be conducted to the inside of the push cylinder 27 by the heat-conducting member 45 (it should be noted that the heat-conducting member 45 is made of brass material and has a strong heat-conducting capacity). When the temperature inside the push cylinder 27 continues to rise, the mercury stored in the push cylinder 27 will undergo thermal expansion reaction, which in turn causes the moving rod 46 to overcome the elastic force of the pressure spring 47 and push the sliding rod 29 to move away from the push cylinder 27. When the sliding rod 29 moves away from the push cylinder 27, it will drive multiple guide plates 25 to deflect toward the heat-conducting layer. When the guide plates 25 move toward the heat-conducting layer During deflection, the filtered cooling water containing bubbles will impact the heat-conducting layer under the guidance of multiple guide plates 25. When the cooling water impacts the heat-conducting layer, it can take away the heat of the heat-conducting layer more quickly, thereby improving the heat exchange efficiency, ensuring the heat exchange effect of the entire lower header 2 on the coal seam, and preventing the coal seam from coking. In addition, the disturbing effect of the bubbles contained in the cooling water can reduce the thermal resistance between the heat-conducting layer and the cooling water, making it easier for the heat conducted by the heat-conducting layer to be transferred to the cooling water, thereby further improving the heat exchange efficiency of the lower header 2. After the lower header 2 impacts the heat-conducting layer, it will evenly flow back into the lower header 2, and then continue to exchange heat with the coal seam through multiple water-cooled walls 5 to generate steam, which is then conducted to the steam drum (this is a prior art and will not be elaborated on in detail).

[0044] Example 2: Please refer to Figure 1 - Fig.16 In the figure, the guide mechanism is arranged on the side of the cleaning mechanism and is linked with the cleaning mechanism. It can guide water according to different usage phenomena. The guide mechanism includes an inner ring 24 arranged inside the header 6, and a plurality of guide plates 25 are rotatably connected to the inner ring 24. The outer sides of the plurality of guide plates 25 are fixedly connected to a flip rod 28. The ends of the plurality of flip rods 28 are rotatably connected to a slide rod 29. The outer wall of the inner ring 24 is fixedly connected to a side plate 26. The outer wall of the side plate 26 is fixedly connected to a push cylinder 27. The inner wall of the push cylinder 27 slides A moving rod 46 is connected, and a pressure spring 47 is sleeved on one side of the moving rod 46 close to the inside of the push cylinder 27. A heat conductor 45 is arranged inside the push cylinder 27. One end of the moving rod 46 away from the pressure spring 47 contacts the end of the slide rod 29. A trigger magnet 30 is fixedly connected to the outer wall of the slide rod 29. The magnetic poles of the trigger magnet 30 are the same as those of the pushing magnet 32. A liquid storage box 7 is fixedly connected to the outer wall of the collecting head 6. One end of the guide pipe 21 away from the sheathing ring 22 is connected to the inside of the liquid storage box 7. A liquid filling port 9 is arranged on the liquid storage box 7.

[0045] In this embodiment, during use, if it is necessary to clean the lower header 2, the operator can close the valves in the multiple water-cooled walls 5 to stop water from flowing inside, and then inject water into the lower header 2 through the water inlet 8. As in the above principle, the water entering the lower header 2 will still be filtered by the filter plate 12. After the lower header 2 is filled with water, the entire boiler body 1 is usually shut down when cleaning the lower header 2. When the boiler body 1 is shut down, the coal seam is no longer burned, and the temperature of the heat exchange layer of the lower header 2 will be greatly reduced. When the temperature of the heat transfer layer is reduced, the mercury in the push cylinder 27 will shrink. At this time, under the elastic force of the pressure spring 47, the moving rod 46 will retract back to its original position. When the moving rod 46 retracts, it will drive the sliding rod 29 to return to its original position in the direction close to the side plate 26. When the sliding rod 29 returns to its original position, the multiple guide plates 25 return to their original positions and no longer deflect the heat transfer layer (refer to Figure 8 ), when the slide bar 29 returns to its original position, it will drive the trigger magnet 30 back to its original position. At this time, the trigger magnet 30 is just above the push magnet 32 ​​in the vertical state (refer to Fig. 9 ), finally, the operator can turn on the dual-axis motor 18 to drive the stirring plate 31 to rotate through the driving shaft 20. When the stirring plate 31 drives the pushing magnet 32 ​​to rotate to the bottom of the triggering magnet 30 (refer to Fig. 9 ), at this time, the distance between the two becomes closer, and under the action of the repulsive magnetic force, the pushing magnet 32 ​​will overcome the elastic force of the damping spring rod 44 and move towards the baffle 33. When the pushing magnet 32 ​​moves towards the baffle 33, the distance to the adsorption magnet 37 becomes closer. At this time, under the action of the attractive magnetic force between the two, the baffle 33 will overcome the elastic force of the pressing spring 35 and move towards the pushing magnet 32 ​​until the bubble making plate 36 is blocked. When the bubble making plate 36 is blocked by the baffle 33, the driving shaft 20 drives the stirring plate 31 to rotate, and the stirring force of the water is increased compared with before. When the baffle plate 33 moves in the direction of pushing the magnet 32, the closing plug 41 is also synchronously driven to move through the connecting rod 43. When the closing plug 41 moves away from the liquid ejection port 42, the chemical liquid stored in the bottom cavity 39 will be ejected into the liquid ejection cavity 40, and finally flow into the manifold head 6 through the liquid ejection port 42, and quickly mix with water under the enhanced stirring of the stirring plate 31, so as to dilute and clean the impurities in the lower manifold 2, thereby ensuring the use effect of the lower manifold 2. When the lower manifold 2 is cleaned, the drain pipe 4 can be opened to release the water in the lower manifold 2, so as to facilitate the normal use of the lower manifold 2.

[0046] It should be noted that when the slide bar 29 is pushed by the moving rod 46 and the entire guide plate 25 is deflected toward the heat transfer layer, the trigger magnet 30 at this time will move together with the slide bar 29, and the trigger magnet 30 at this time will be away from the pushing magnet 32. Even if the stirring plate 31 drives the pushing magnet 32 ​​to rotate close to the trigger magnet 30, the distance between the trigger magnet 30 located diagonally above the pushing magnet 32 ​​is still far, and the magnetic force is weak, which is not enough to make the pushing magnet 32 ​​move toward the inside of the stirring plate 31. When the pushing magnet 32 ​​no longer moves toward the inside of the stirring plate 31, the baffle 33 will not be adsorbed to block the bubble making plate 36. When the baffle 33 does not move, the closing plug 41 will block the liquid ejection port 42, and the liquid ejection port 42 will not eject liquid outward.

[0047] It should also be noted that the damping spring rod 44 has a faster contraction speed and a slower rebound speed (this is the prior art and will not be elaborated on in detail). When the lower collecting box 2 needs to be cleaned, under the above principle, the pushing magnet 32 ​​will be pushed toward the inside of the stirring plate 31. When the stirring plate 31 drives the pushing magnet 32 ​​away from the triggering magnet 30, the magnetic force between the two disappears, and the damping spring rod 44 with a slower rebound speed has no time to bounce the pushing magnet 32 ​​back to its original position, and the pushing magnet 32 ​​will rotate again with the stirring plate 31 to the bottom of the triggering magnet 30. Therefore, as long as the stirring plate 31 rotates and the triggering magnet 30 is in its normal position, the pushing magnet 32 ​​will always move toward the inside of the stirring plate 31. Correspondingly, when the lower collecting box 2 is cleaned, the baffle 33 will always block the bubble making plate 36 when the stirring plate 31 rotates.

[0048] It should also be noted that when the dual-axis motor 18 drives the stirring plate 31 to rotate via the driving shaft 20, it will also drive the through hole 48 to rotate. When the through hole 48 rotates to coincide with the open end of the guide tube 21, the chemical liquid in the liquid storage box 7 will pass through the guide tube 21 and then through the through hole 48 into the guide groove 38, and will be transported through the guide groove 38 to the bottom cavity 39 for storage.

[0049] It should also be noted that after the impurities on the filter plate 12 are scraped off, they will enter the sewage storage tank 10 together with the cooling water through the one-way slot 14. Since the sewage storage tank 10 is provided with an inner filter plate 19, the impurities can be filtered and retained inside the sewage storage tank 10, and the filtered cooling water will flow back to the collecting head 6 through the water pipe 11. Since the one-way slot 14 is a one-way design, the impurities entering the sewage storage tank 10 will not return to the collecting head 6 again through the one-way slot 14.

[0050] It should also be noted that when the trigger magnet 30 is in its normal original position, as long as the stirring plate 31 rotates, the baffle 33 blocks the bubble making plate 36 under the above principle. In the drawings of the specification, this process is not shown for the sake of demonstration, and the dual-axis motor 18 has a positioning function. When the dual-axis motor 18 stops rotating, the two stirring plates 31 are in a horizontal state away from the trigger magnet 30 (this is a prior art and will not be elaborated on in detail).

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
