Description

Technical Field

[0001] The invention relates to the technical field of waste incineration fly ash, and in particular to an integrated special softening membrane system for waste incineration fly ash. Background Art

[0002] The softening membrane used for waste incineration fly ash has a special structure and properties, which can effectively remove harmful substances in fly ash and meet environmental protection and safety standards. Special softening membranes are usually made of materials with excellent separation properties, such as high molecular polymers or inorganic materials. These materials have good chemical stability, heat resistance and corrosion resistance, and can adapt to the complex environment during the treatment of waste incineration fly ash. The design of special softening membranes takes into account the separation requirements of different substances in fly ash. The characteristics of membrane materials such as pore size, surface properties and charge are precisely controlled to achieve selective separation of specific substances. For example, membrane materials can be designed to have specific adsorption and interception capabilities for heavy metal ions, thereby effectively removing heavy metal pollution in fly ash.

[0003] The specific process of heavy metal ion membrane separation of waste incineration fly ash is as follows: first, the waste incineration fly ash is pretreated, including crushing, screening and other steps. Then, the pretreated fly ash is mixed with water or other solvents to form fly ash slurry. Then, the fly ash slurry is introduced into the membrane separation equipment. The membrane separation equipment adsorbs heavy metal ions. The fly ash slurry passes through the membrane under pressure, while harmful substances or target components are retained in the membrane. Large fly ash particles in the slurry are easy to block the softening membrane, affecting the separation effect of the softening membrane. Therefore, in order to ensure the efficient operation of the softening membrane, it is necessary to clean the softening membrane regularly to remove accumulated pollutants and prevent the membrane pores from being blocked, so as to maintain the separation performance of the membrane. However, the softening membrane cleaning process wastes time, resulting in low efficiency of heavy metal ions in waste incineration fly ash. It is necessary to design an integrated special softening membrane system with a secondary crushing function to crush larger fly ash particles in the slurry for the second time, ensure that the fly ash particle size is appropriate, and reduce the cleaning frequency of the softening membrane. In view of this, we propose an integrated special softening membrane system for waste incineration fly ash. Summary of the invention

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

[0017] 1. The present invention provides a secondary crushing mechanism to perform secondary crushing on the fly ash slurry with larger fly ash particles, thereby reducing the blockage frequency of the softening membrane, improving the softening membrane separation effect, and solving the current technical problem of low separation efficiency of heavy metal ion membranes for waste incineration fly ash.

[0018] 2. The present invention can reduce the number of larger fly ash particles at the end of the crushing ball block near the outlet by setting the crushing ball block to be spherical, and sets the crushing ball block and the crushing groove B and the crushing groove A to be gear-connected, which not only ensures the stability of the rotational crushing of the crushing ball block, but also increases the contact area between the crushing ball block and the crushing groove B and the crushing groove A, thereby further improving the grinding effect.

[0019] 3. The present invention arranges the first water supply plate and the second water supply plate in reverse arrangement with an inclined structure, and the third water supply plate in forward arrangement with an inclined structure. The inclined structure arrangement enhances the centrifugal force, and can discharge the fly ash slurry with mostly smaller fly ash particles from the filter hole. Compared with the traditional vertically arranged water supply plate structure, its horizontal conveying capacity is deteriorated, so that the conveying speed of the fly ash slurry with larger fly ash particles is slowed down, and the grinding effect of the crushed ball blocks is improved. The third water supply plate is arranged in reverse arrangement relative to the first water supply plate and the second water supply plate, so that the third water supply plate has a horizontal reverse conveying force for the slurry at the corresponding position, so that the fly ash particles that have not been crushed to a qualified level through all the crushed ball blocks can flow in the reverse direction, so that the crushed ball blocks close to each other are aligned for re-grinding, and it is prevented that larger fly ash particles are accumulated at the third water supply plate, and finally affect the rotation of the third water supply plate.

[0020] 4. The present invention arranges a guide plate so that the rotation of the outer tube drives the guide plate to rotate, and the fly ash slurry in the gap between the outer tube and its inner components is accelerated and sent to the return port to merge with the main pipe slurry, thereby accelerating the main pipe slurry and increasing the flow rate of the main pipe slurry, thereby improving the heavy metal ion membrane separation efficiency of waste incineration fly ash.

[0021] 5. The present invention further designs the transmission mechanism. When the engaging gear B engages with the engaging gear ring, the engaging block disengages from the engaging gear A, and the engaging portion of the engaging block engages with the engaging groove on the inner side, so that the mounting ring block C cannot rotate relative to the engaging gear ring. The motor is controlled by an external control mechanism, and the output end of the motor drives the connecting shaft and the transmission gear to rotate, so that the double-sided ring gear drives the planetary gear to rotate, so that the outer ring gear rotates in the opposite direction relative to the double-sided ring gear, so that the inner tube and the outer tube rotate in the opposite direction, and the rotation of the inner tube drives the first water delivery component to rotate, and part of the inner tube has The fly ash slurry with smaller fly ash particles flows out from the filter holes, and the fly ash slurry with larger fly ash particles is sent to the crushing ball block. The inner tube rotates to cause the crushing ball block to revolve around the crushing slot B to crush the fly ash particles. After the crushing is qualified, the fly ash slurry flows out from the filter holes as the slurry flows. The outer tube rotates to drive the guide plate to rotate, and the fly ash slurry in the gap between the outer tube and its inner parts is accelerated to the return port to merge with the main through pipe slurry, accelerate the main through pipe slurry flow rate, and improve the heavy metal ion membrane separation efficiency of waste incineration fly ash;

[0022] When the engaging gear B is engaged with the engaging gear A, the engaging block is disengaged from the engaging gear ring, and the engaging portion of the engaging block is engaged with the engaging groove on the outside, so that the engaging gear A and the planetary gear cannot rotate, causing the outer tube to rotate and drive the planetary gear and the inner tube to rotate in the same direction, and the guide plate to rotate in the opposite direction, thereby decelerating the fly ash slurry in the gap between the outer tube and its inner component, reducing the flow rate of the fly ash slurry in the secondary crushing mechanism, and further improving the grinding effect. This is suitable for situations where the fly ash slurry contains more large fly ash particles, and prevents the large fly ash particles from further accumulating on the third water supply plate.

[0023] 6. The present invention provides a plurality of oblique guide grooves on the mounting ring block D, so that the mounting ring block D can rotate to cause all the oblique guide grooves to rotate and squeeze the corresponding rotating rods B, so that all the rotating rods B drive the corresponding sliders to slide along the corresponding centripetal grooves, and the positions of all the engaging gears B are adjusted synchronously, which is convenient for adjustment.

[0024] 7. The present invention arranges the engaging teeth of the engaging gear B, the engaging gear A and the engaging gear ring to be triangular in shape, so that the two ends of the engaging gear B are not easily stuck when they are respectively engaged with the engaging gear A and the engaging gear ring, and the eccentric arrangement of the engaging gear B relative to the engaging gear A and the engaging gear ring avoids the situation where the sharp angles of the gear teeth are relative to each other when the two ends of the engaging gear B are respectively engaged with the engaging gear A and the engaging gear ring.

[0039] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0040] Example 1: An integrated special softening membrane system for waste incineration fly ash, see Figures 1 to 6 , including a softening mechanism 1, a secondary crushing mechanism 2 and a transmission mechanism 3. The softening mechanism 1 includes a main through-tube 10, on which a filter plate 11 and a softening membrane unit 12 are arranged in sequence. The main through-tube 10 is provided with a plurality of outlets 13 in an annular structure with equal spacing relative to the filter plate 11, and the main through-tube 10 is provided with a plurality of return ports 14 in an annular structure with equal spacing relative to the gap between the filter plate 11 and the softening membrane unit 12; the main through-tube 10 is fixedly provided with a mounting ring block A15 at a position relative to the return port 14, the mounting ring block A15 has a trapezoidal cross-section, a rotating groove A16 is provided at the top of the mounting ring block A15 near the outlet 13, the mounting ring block A15 is provided with a plurality of crushing grooves A17 with arc-shaped cross-sections at a position relative to the secondary crushing mechanism 2, and a plurality of crushing teeth A18 are fixedly provided on the crushing groove A17 in an annular structure with equal spacing.

[0041] Furthermore, the secondary crushing mechanism 2 is arranged on the main through pipe 10 relative to the plurality of outlets 13, the input end of the secondary crushing mechanism 2 is connected to the outlet 13, and the output end of the secondary crushing mechanism 2 is connected to the return port 14; its specific structure is that the secondary crushing mechanism 2 includes an inner tube 21, the tail end of the inner tube 21 is rotatably connected to the rotating groove A16, the head end of the inner tube 21 is rotatably connected to the main through pipe 10 through a mechanical sealing structure A22, and the inner tube 21 is provided with a plurality of cross-sections of The crushing groove B23 is arc-shaped, and a plurality of crushing teeth B24 are fixedly arranged in an annular equidistant structure on the crushing groove B23. A plurality of crushing balls 25 are movably arranged in an annular equidistant structure in any corresponding crushing groove B23 and crushing groove A17 in the crushing cavity. A plurality of crushing tooth grooves 26 are opened in an annular equidistant structure on the crushing ball block 25. The crushing tooth grooves 26 are movably matched with the corresponding plurality of crushing teeth A18. The inner tube 21 is opened with a plurality of groups of filter holes 27 at positions corresponding to the plurality of crushing grooves B23. The present invention can reduce the number of large fly ash particles at the end of the crushing ball block 25 near the outlet 13 by setting the crushing ball block 25 to be spherical, and the crushing ball block 25 is set to be connected with the crushing groove B23 and the crushing groove A17 by teeth, which not only ensures the stability of the rotational crushing of the crushing ball block 25, but also increases the contact area between the crushing ball block 25 and the crushing groove B23 and the crushing groove A17, thereby further improving the grinding effect.

[0042] Furthermore, a first water supply assembly 28 is arranged on the inner surface of the inner tube 21. The first water supply assembly 28 includes a plurality of first water supply plates 281, a plurality of groups of second water supply plates 282 and a plurality of third water supply plates 283. The plurality of first water supply plates 281 are fixedly arranged on the inner surface of the inner tube 21 in a circular and equidistant structure relative to the outlet 13, and the plurality of groups of second water supply plates 282 are fixedly arranged on the inner surface of the inner tube 21 relative to the gap positions of the plurality of crushing grooves B23. Moreover, each group of second water supply plates 282 includes a plurality of water supply plates 282 arranged in a circular and equidistant manner, and the plurality of third water supply plates 283 are fixedly arranged on the inner surface of the inner tube 21 relative to the mechanical sealing structure A22. Through the above arrangement, the present invention allows the inner tube 21 to rotate and drive the first water supply assembly to rotate, so that part of the fly ash slurry with smaller fly ash particles goes out from the filter hole 27, and the fly ash slurry with larger fly ash particles is sent to the crushing ball block 25. The rotation of the inner tube 21 causes the crushing ball block 25 to revolve around the crushing groove B23 to crush the fly ash particles. After the crushing is qualified, the fly ash slurry also goes out from the filter hole 27 along with the slurry flow.

[0043] It is worth noting that the first water supply plate 281, the second water supply plate 282 and the third water supply plate 283 are all in contact with and connected to the main through pipe 10, and the first water supply plate 281, the second water supply plate 282 and the third water supply plate 283 are all partially threaded structures;

[0044] The first water supply plate 281 and the second water supply plate 282 are both arranged in reverse direction in an inclined structure, and the third water supply plate 283 is arranged in forward direction in an inclined structure. The present invention arranges the first water supply plate 281 and the second water supply plate 282 in an inclined structure in reverse arrangement, and the third water supply plate 283 in an inclined structure in forward arrangement. The inclined structure arrangement enhances the centrifugal force, and can allow the fly ash slurry with mostly smaller fly ash particles to pass through the filter hole 27. Compared with the traditional vertically arranged water supply plate structure, its horizontal conveying capacity is poor, so that the conveying speed of the fly ash slurry with larger fly ash particles is slowed down, thereby improving the grinding effect of the crushed ball block 25. The third water supply plate 283 is arranged in the opposite direction to the first water supply plate 281 and the second water supply plate 282, so that the third water supply plate 283 has a horizontal reverse conveying force for the slurry at the corresponding position, so that the fly ash particles that have not been crushed to a qualified level of all the crushed ball blocks 25 can flow in the reverse direction through accident, so that the crushed ball blocks 25 that are close to each other are aligned for re-grinding, and it is prevented that larger fly ash particles accumulate at the third water supply plate 283, and finally affect the rotation of the third water supply plate 283.

[0045] It is worth noting that the secondary crushing mechanism 2 also includes an outer tube assembly 29, which includes an outer tube 291. The head end of the outer tube 291 is rotatably connected to the inner tube 21 through a mechanical sealing structure B292. The tail of the outer tube 291 is adapted to the mounting ring block A15. The gap between the outer tube 291 and the mounting ring block A15 constitutes a backflow chamber. A mounting ring block B293 is fixedly provided at the tail end of the outer tube 291. The mounting ring block B293 is rotatably connected to the main through pipe 10 through a mechanical sealing structure C294. A spiral guide plate 295 is fixedly provided on the outer tube 291. The tail of the guide plate 295 is adapted to the backflow chamber, and the guide plate 295 has a hollow structure. The present invention sets a guide plate 295 so that the rotation of the outer tube 291 drives the guide plate 295 to rotate, and the fly ash slurry in the gap between the outer tube 291 and its inner components is accelerated and sent to the return port 14 to merge with the slurry in the main tube 10, thereby accelerating the slurry in the main tube 10 and increasing the flow rate of the slurry in the main tube 10, thereby improving the heavy metal ion membrane separation efficiency of the waste incineration fly ash. When the rotation of the outer tube 291 drives the guide plate 295 to rotate in the opposite direction relative to the above-mentioned method, the fly ash slurry in the gap between the outer tube 291 and its inner components is decelerated, and the flow rate of the fly ash slurry in the secondary crushing mechanism 2 is reduced, thereby further improving the grinding effect. This is suitable for the situation where the fly ash slurry contains a large number of larger fly ash particles, and prevents the larger fly ash particles from further accumulating on the third water supply plate 283.

[0046] It is worth mentioning that the transmission mechanism 3 is arranged on the main through-tube 10 relative to the secondary crushing mechanism 2, and the transmission mechanism 3 is connected to the secondary crushing mechanism 2. Its specific structure is that the transmission mechanism 3 includes an outer ring tooth 31, a double-sided ring tooth 32, a mounting ring block C33 and a mounting seat 37. The outer ring tooth 31 is fixedly arranged at the head end of the inner tube 21, and the double-sided ring tooth 32 is fixedly arranged at the head end of the outer tube 291. The mounting ring block C33 is movably installed on the main through-tube 10 relative to the outer ring tooth 31. A plurality of rotating seats A34 are fixedly arranged on the mounting ring block C33 in an annular equidistant structure. The rotating seat A34 is fixedly arranged on the mounting ring block C33. A rotating rod A35 is rotatably connected to 34, and a planetary gear 36 is fixedly arranged on the rotating rod A35. The two ends of the planetary gear 36 are respectively meshed with the outer end of the outer ring tooth 31 and the inner end of the double-sided ring tooth 32. A mounting seat 37 is fixedly arranged at the head of the main through pipe 10 relative to the double-sided ring tooth 32. A motor 38 is fixedly arranged on the mounting seat 37. A connecting shaft 39 is fixedly arranged at the output end of the motor 38. The connecting shaft 39 is rotatably connected to the mounting seat 37 through a rotating seat B310. A transmission gear 311 is fixedly arranged at the tail end of the connecting shaft 39. The transmission gear 311 is meshed with the outer end of the double-sided ring tooth 32. The present invention arranges the transmission mechanism 3 as described above so that when the mounting ring block C33 is relatively unable to rotate, the motor 38 is controlled by an external control mechanism, and the output end of the motor 38 drives the connecting shaft 39 and the transmission gear 311 to rotate, causing the double-sided ring gear 32 to drive the planetary gear 36 to rotate, causing the outer ring gear 31 to rotate in the opposite direction relative to the double-sided ring gear 32, causing the inner tube 21 and the outer tube 291 to rotate in the opposite direction.

[0047] The end of the rotating rod A35 away from the planetary gear 36 passes through the rotating seat A34 and is fixed with a clamping gear A312. In addition, a centripetal sliding groove 313 is provided at the end of the connecting portion of the rotating seat A34 away from the planetary gear 36. The centripetal sliding groove 313 is provided with two clamping grooves 314. The centripetal sliding groove 313 is slidably connected with a slider 315. A sliding hole 316 is provided in the slider 315. A clamping block 317 is provided in the sliding hole 316. The clamping block 317 is adapted to the clamping groove 314, and the clamping portion of the clamping block 317 is hemispherical. The clamping portion of the clamping block 317 is clamped and matched with the two clamping grooves 314. The clamping block 317 and the sliding hole 316 are elastically connected by a spring 318.

[0048] The transmission mechanism 3 also includes a mounting ring block D319 and a snap-on gear ring 324. A protective ring block 320 with an adjustment block is fixedly provided on the outer edge surface of the mounting ring block D319. A plurality of inclined guide grooves 321 are provided on the mounting ring block D319 relative to the plurality of centripetal slide grooves 313. A rotating rod B322 is movably connected to the inclined guide groove 321. The rotating rod B322 is fixedly connected to the slider 315. A snap-on gear B323 is fixedly provided on the rotating rod B322 relative to the snap-on gear A312. The snap-on gear ring 324 is fixedly provided on the main through pipe 10 relative to the snap-on gear B323. The two ends of the snap-on gear B323 are snap-fitted with the snap-on gear A312 and the snap-on gear ring 324 respectively. The present invention further designs the transmission mechanism 3 as mentioned above, so that when the engaging gear B323 is engaged with the engaging gear A312, the engaging block 317 is disengaged from the engaging gear ring 324, and the engaging portion of the engaging block 317 is engaged with the outer engaging groove 314, so that the engaging gear A312 and the planetary gear 36 cannot rotate, causing the outer tube 291 to rotate and drive the planetary gear 36 and the inner tube 21 to rotate in the same direction. According to the above principle, it can be known that the guide plate 295 rotates in the opposite direction relative to the above method, decelerating the fly ash slurry in the gap between the outer tube 291 and its inner parts, reducing the flow rate of the fly ash slurry in the secondary crushing mechanism 2, and further improving the grinding effect. It is suitable for the situation where the fly ash slurry contains more large fly ash particles, and prevents the large fly ash particles from further accumulating on the third water supply plate 283.

[0049] Moreover, the present invention provides a plurality of inclined guide grooves 321 on the mounting ring block D319, so that the rotation of the mounting ring block D319 can cause all the inclined guide grooves 321 to rotate and squeeze the corresponding rotating rods B322, so that all the rotating rods B322 drive the corresponding sliders 315 to slide along the corresponding centripetal grooves 313, and synchronously adjust the positions of all the engaging gears B323, which is convenient for adjustment.

[0050] It is worth emphasizing that the engaging teeth of the engaging gear B323, the engaging gear A312 and the engaging gear ring 324 are all triangular in shape, and the engaging gear B323 is arranged eccentrically relative to the engaging gear A312 and the engaging gear ring 324. The present invention sets the engaging teeth of the engaging gear B323, the engaging gear A312 and the engaging gear ring 324 to be triangular in shape, so that the two ends of the engaging gear B323 are not easily stuck when they are respectively engaged with the engaging gear A312 and the engaging gear ring 324, and the eccentric arrangement of the engaging gear B323 relative to the engaging gear A312 and the engaging gear ring 324 avoids the situation where the sharp angles of the gear teeth are opposite to each other when the two ends of the engaging gear B323 are respectively engaged with the engaging gear A312 and the engaging gear ring 324.

[0051] The present invention provides a secondary pulverizing mechanism 2 to perform secondary pulverization on fly ash slurry with larger fly ash particles, thereby reducing the clogging frequency of the softening membrane, improving the softening membrane separation effect, and solving the current technical problem of low heavy metal ion membrane separation efficiency of waste incineration fly ash.

[0052] Working principle: Working principle of embodiment 1, the head end of the main through pipe 10 is connected to the output end of the mechanism for pre-treating the fly ash from garbage incineration, most of the fly ash slurry passes through the filter plate 11 and the softening membrane unit 12 to complete the separation of heavy metal ions, and the fly ash slurry with larger fly ash particles enters the secondary crushing mechanism 2 for secondary crushing;

[0053] When the engaging gear B323 is engaged with the engaging gear ring 324, the engaging block 317 is disengaged from the engaging gear A312, and the engaging portion of the engaging block 317 is engaged with the engaging groove 314 on the inner side, so that the mounting ring block C33 cannot rotate relative to the engaging gear ring 324. The motor 38 is controlled by an external control mechanism, and the output end of the motor 38 drives the connecting shaft 39 and the transmission gear 311 to rotate, so that the double-sided ring gear 32 drives the planetary gear 36 to rotate, so that the outer ring gear 31 rotates in the opposite direction relative to the double-sided ring gear 32, so that the inner tube 21 rotates in the opposite direction to the outer tube 291, and the rotation of the inner tube 21 drives the first water delivery component to rotate, and part of the inner tube 21 has a rotation. The fly ash slurry with smaller fly ash particles goes out from the filter hole 27, and the fly ash slurry with larger fly ash particles is sent to the crushing ball block 25. The inner tube 21 rotates to cause the crushing ball block 25 to revolve around the crushing slot B23 to crush the fly ash particles. After the crushing is qualified, the fly ash slurry also goes out from the filter hole 27 along with the slurry flow. The outer tube 291 rotates to drive the guide plate 295 to rotate, and the fly ash slurry in the gap between the outer tube 291 and its inner parts is accelerated to the return port 14 to merge with the slurry in the main through pipe 10, and the slurry in the main through pipe 10 is accelerated to increase the flow rate of the slurry in the main through pipe 10, thereby improving the heavy metal ion membrane separation efficiency of the waste incineration fly ash;

[0054] Among them, by setting the engaging teeth of the engaging gear B323, the engaging gear A312 and the engaging gear ring 324 to be triangular in shape, it is not easy for the engaging gear B323 to get stuck when the two ends of the engaging gear B323 are respectively engaged with the engaging gear A312 and the engaging gear ring 324, and the eccentric arrangement of the engaging gear B323 relative to the engaging gear A312 and the engaging gear ring 324 avoids the situation where the sharp angles of the gear teeth are relative to each other when the two ends of the engaging gear B323 are respectively engaged with the engaging gear A312 and the engaging gear ring 324.

[0055] A plurality of oblique guide grooves 321 are provided on the mounting ring block D319, so that the mounting ring block D319 rotates to cause all oblique guide grooves 321 to rotate and squeeze the corresponding rotating rods B322, so that all rotating rods B322 drive the corresponding sliders 315 to slide along the corresponding centripetal sliding grooves 313, and adjust the positions of all the clamping gears B323 synchronously, which is convenient for adjustment;

[0056] The first water supply plate 281 and the second water supply plate 282 are arranged in reverse with an inclined structure, and the third water supply plate 283 is arranged in a forward with an inclined structure. The inclined structure arrangement enhances the centrifugal force, and can discharge the fly ash slurry with mostly small fly ash particles from the filter hole 27. Compared with the traditional vertically arranged water supply plate structure, its horizontal conveying capacity is poor, so that the conveying speed of the fly ash slurry with large fly ash particles is slowed down, and the grinding effect of the crushed ball block 25 is improved. The third water supply plate 283 is arranged in reverse with respect to the first water supply plate 281 and the second water supply plate 282, so that the third water supply plate 283 has a horizontal reverse conveying force for the slurry at the corresponding part, so that the fly ash particles that have not been crushed to the qualified state of all the crushed ball blocks 25 can flow in reverse through the accident, so that the crushed ball blocks 25 that are close to each other are aligned for re-grinding, and large fly ash particles are prevented from accumulating more at the third water supply plate 283, and finally affecting the rotation of the third water supply plate 283.

[0057] The crushing ball block 25 is spherical to reduce the number of larger fly ash particles at the end of the crushing ball block 25 near the outlet 13. The crushing ball block 25 is connected to the crushing groove B23 and the crushing groove A17 by teeth, which not only ensures the stability of the rotation and crushing of the crushing ball block 25, but also increases the contact area between the crushing ball block 25 and the crushing groove B23 and the crushing groove A17, thereby further improving the grinding effect.

[0058] When the engaging gear B323 is engaged with the engaging gear A312, the engaging block 317 is disengaged from the engaging gear ring 324, and the engaging portion of the engaging block 317 is engaged with the engaging groove 314 on the outside, so that the engaging gear A312 and the planetary gear 36 cannot rotate, causing the outer tube 291 to rotate and drive the planetary gear 36 and the inner tube 21 to rotate in the same direction. According to the above principle, it can be seen that the guide plate 295 rotates in the opposite direction relative to the above method, and slows down the fly ash slurry in the gap between the outer tube 291 and its inner parts, reducing the flow rate of the fly ash slurry in the secondary crushing mechanism 2, further improving the grinding effect, and is suitable for the situation where the fly ash slurry contains more large fly ash particles, preventing the large fly ash particles from further accumulating on the third water supply plate 283.

[0059] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
