The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] This invention provides a fly ash and slag concrete filtration device, such as... Figure 1-10 As shown, the fly ash slag concrete filtration device includes: a housing 1 and a filter screen 2 slidably disposed within the housing 1 for filtering fly ash slag; a first guide rod 3 fixedly installed within the housing 1, on which a first guide plate 4 is slidably sleeved; an exhaust pipe 5 fixedly installed on the first guide plate 4 for flushing the filter screen 2 with high-pressure gas, the exhaust pipe 5 being located below the filter screen 2; a scraper 20 disposed within the housing 1 for cleaning slag from the filter screen 2; and two sets of moving mechanisms disposed on the housing 1 for driving the exhaust pipe 5 and the scraper 20 to reciprocate, each moving mechanism including: a connecting box 6 fixedly installed on one side of the housing 1; a rotating drum 7 rotatably installed within the connecting box 6, on which a pull rope 8 for pulling the first guide plate 4 is wound; and a shaking mechanism disposed on the housing 1 for driving the filter screen 2 to shake to improve filtration efficiency.

[0032] In this embodiment, when the system starts the unblocking program, the first motor 14 drives the rotating plate 12 to make a circular motion through the transmission shaft. Since the rotating plate 12 is connected to the connecting rod 13 by a hinge, the lower end of the connecting rod 13 will periodically move up and down during the rotation of the rotating plate. The connecting rod 13 is connected to the filter screen 2 frame through a round rod. Under the elastic support of the buffer spring 30, the filter screen 2 will shake up and down to screen the slag on the filter screen 2.

[0033] When it is necessary to clean the filtered material, the second motor 21 is started, which drives the drum 7 to rotate. The first guide plate 4 is pulled along the first guide rod 3 by the pull rope 8, which drives the exhaust pipe 5 to move laterally. At the same time, another set of pull ropes 8 drives the second guide plate 19 and scraper 20 to move synchronously, scraping off the slag accumulated on the surface of the filter screen 2, so that the slag is discharged through the exhaust pipe 17. Then the scraper 20 and exhaust pipe 5 are reset. After reset, the external high-pressure air supply equipment supplies air to the exhaust pipe 5. Then the moving mechanism is started again, so that the exhaust pipe 5 moves laterally and the high-pressure gas is sprayed upward from the exhaust pipe 5 to backwash the filter screen pores and clean the impurities in the filter screen 2.

[0034] By setting up a shaking mechanism, the first motor 14 drives the rotating plate 12 to make circular motion, causing the connecting rod 13 to move up and down periodically. This causes the filter screen 2 to shake up and down under the elastic support of the buffer spring 30, which can screen the slag on the filter screen 2 and effectively improve the filtration efficiency of the filter screen 2. By moving the mechanism, the exhaust pipe 5 moves laterally, and high-pressure gas is sprayed upward from the exhaust pipe 5 to backwash the pores of the filter screen 2, effectively removing the slag stuck in the filter holes. This avoids the filter holes from being blocked, which would reduce the filtration efficiency of the filter screen 2 and ensure the smooth operation of the filtration of fly ash slag.

[0035] In a further preferred embodiment of the present invention, the shaking mechanism includes: a connecting plate 9 fixedly installed at the bottom of the filter screen 2; a U-shaped frame 10 disposed below the filter screen 2, wherein a connecting rod 11 is fixedly installed on the top of the U-shaped frame 10 and the connecting rod 11 is slidably connected to the connecting plate 9; a rotating plate 12 rotatably installed on one side of the inner wall of the housing 1; a connecting rod 13 respectively hinged to the bottom of the rotating plate 12 and the U-shaped frame 10; and a first motor 14 fixedly installed on one side of the housing 1 for driving the rotating plate 12 to rotate, wherein the output shaft of the first motor 14 is fixedly connected to the rotating shaft of the rotating plate 12.

[0036] In this embodiment, the output shaft of the first motor 14 directly drives the rotating plate 12 to rotate. The hinged connecting rod 13 converts the circular motion into the vertical reciprocating motion of the U-shaped frame 10. Through the arrangement of the round rod 32 and the support plate 29, it is ensured that the filter screen 2 only makes linear shaking in the vertical direction. The eccentric effect of the rotating plate 12 generates periodic impact force, enabling the filter screen 2 to quickly screen the material. The output shaft of the hot air first motor 14 directly drives the rotating plate 12 to rotate. The hinged connecting rod 13 cleverly converts the circular motion of the rotating plate 12 into the vertical reciprocating motion of the U-shaped frame 10. This motion conversion design is simple and efficient, providing a stable and continuous power source for the shaking of the filter screen 2. The eccentric effect of the rotating plate 12 can generate periodic impact force. This periodic impact force acts on the filter screen 2, enabling the filter screen 2 to quickly and fully screen the material.

[0037] In a further preferred embodiment of the present invention, a first discharge hopper 15 is fixedly installed inside the box 1. The first discharge hopper 15 is located below the rotating plate 12. A conveyor belt 16 for discharging filtered slag is provided at the bottom of the inner wall of the box 1. The conveyor belt 16 extends out of the box 1.

[0038] In this embodiment, the filtered fine slag particles fall through the filter screen 2 into the first discharge hopper 15, and are concentrated by the conical guide to the conveyor belt 16. The conveyor belt 16 transports the filtered material to the outside of the box 1 at a constant speed, realizing continuous discharge. With the help of the conical guide structure, the first discharge hopper 15 can effectively concentrate the scattered slag, preventing the slag from scattering everywhere in the box 1, improving the efficiency and integrity of slag collection, and enabling the filtered slag to smoothly converge to the designated location. Through the cooperation of the first discharge hopper 15 and the conveyor belt 16, the filtered slag is discharged from the box 1 in a timely and orderly manner, reducing the material residue in the box 1.

[0039] In a further preferred embodiment of the present invention, a discharge pipe 17 is fixedly installed on one side of the housing 1, the discharge pipe 17 is located on one side of the filter screen 2, and a discharge port is opened on one side of the housing 1, the discharge port being connected to the discharge pipe 17.

[0040] In this embodiment, the coarse slag particles pushed by the scraper 20 move along the filter screen 2 and enter the discharge pipe 17 through the discharge port. The third motor 28 opens the cover plate 27 according to the set cycle, so that the coarse slag is automatically discharged under the action of gravity, avoiding manual cleaning. When the scraper 20 pushes the slag along the filter screen 2, the slag can smoothly enter the discharge pipe 17 through the discharge port, so that the discharge process of coarse slag particles is orderly and controllable, and the slag is prevented from accumulating on the filter screen 2.

[0041] In a further preferred embodiment of the present invention, a second guide rod 18 is fixedly installed inside the housing 1. The second guide rod 18 is located above the filter screen 2, and a second guide plate 19 is slidably sleeved on the second guide rod 18. The scraper 20 is fixedly connected to the bottom of the second guide plate 19, and the second guide plate 19 is connected to another set of pull ropes 8. A second motor 21 for driving the rotating drum 7 to wind and unwind the pull ropes 8 is fixedly installed on one side of the connecting box 6. The output shaft of the second motor 21 is fixedly connected to the rotating shaft of the rotating drum 7.

[0042] In this embodiment, the second motor 21 directly drives the rotating drum 7 to rotate in both directions via its output shaft, thereby enabling the winding and unwinding of the pull rope 8. The second guide plate 19 slides along the second guide rod 18 to ensure that the scraper 20 maintains a horizontal movement trajectory. The two sets of moving mechanisms achieve asynchronous speeds through the differential sprocket 24, causing the scraper 20 and the exhaust pipe 5 to move at different speeds. This results in the exhaust pipe 5 sliding a distance less than that of the scraper 20, thus preventing the exhaust pipe 5 from contacting the support plate 29. The second motor 21 directly drives the rotating drum 7 to rotate in both directions via its output shaft, thereby enabling the winding and unwinding of the pull rope 8 and driving the second guide plate 18 and the scraper 20 to move. This direct drive method has a simple structure and high transmission efficiency, and can achieve stable control of the scraper 20's moving speed and direction, making it easy to adjust the cleaning rhythm of the scraper 20 according to actual production needs.

[0043] In a further preferred embodiment of the present invention, a first sprocket 22 is fixedly sleeved on the output shaft of each of the two sets of rotating drums 7, and a first chain 23 is sleeved on each of the two sets of first sprockets 22. The first chain 23 meshes with the first sprocket 22. A differential sprocket 24 is sleeved on each of the two sets of first sprockets 22, and a second chain 25 is sleeved on each of the two differential sprockets 24. The second chain 25 meshes with the two differential sprockets 24. A protective cover 26 for protecting the second motor 21, the first chain 23 and the second chain 25 is installed on one side of the housing 1.

[0044] In this embodiment, when the second motor 21 drives the active rotating drum 7 to rotate, power is transmitted to the driven rotating drum 7 through the first sprocket 22 and the first chain 23. The differential sprocket 24 and the second chain 25 cause a deviation in the rotational speed of the two sets of rotating drums 7, making the sliding distance of the exhaust pipe 5 less than that of the scraper 20. At the same time, the protective cover 26 prevents the chain from interfering with the outside. By fixing the first sprocket 23 on the output shaft of the two sets of rotating drums 7 and using the first chain 24 to mesh with the first sprocket 23 to achieve power transmission, this sprocket and chain transmission method has the characteristics of accurate transmission ratio, large power transmission, and high efficiency. When the second motor 21 drives the active rotating drum 7 to rotate, it can stably transmit power to the driven rotating drum 7, ensuring that the two sets of moving mechanisms operate synchronously and reliably, providing power guarantee for the normal movement of the scraper 20 and the exhaust pipe 5.

[0045] In a further preferred embodiment of the present invention, a cover plate 27 for sealing the discharge port is rotatably installed inside the discharge port, and a third motor 28 for driving the cover plate 27 to open and close is fixedly installed on one side of the housing 1, and the output shaft of the third motor 28 is fixedly connected to the rotating shaft of the cover plate 27.

[0046] In this embodiment, while the scraper 20 scrapes the material, the control system activates the third motor 28. After receiving the control signal, the third motor 28 drives the cover plate 27 to rotate 90° through its output shaft, opening the discharge port so that the material is discharged through the discharge port and the discharge pipe 17. When the scraper 20 resets, the cover plate 27 is closed to prevent material leakage from the discharge port. Through the precise control of the third motor 28 by the control system, the opening and closing time and frequency of the discharge port can be flexibly adjusted according to actual production needs, thereby adapting to different production rhythms and material processing volumes.

[0047] In a further preferred embodiment of the present invention, a buffering mechanism for buffering the vibration of the filter screen 2 is provided on one side of the inner wall of the housing 1. The buffering mechanism includes: a support plate 29 fixedly installed on one side of the inner wall of the housing 1 and located below the filter screen 2; a buffer spring 30 fixedly installed on the top of the support plate 29; a T-shaped rod 31 fixedly installed on the top of the buffer spring 30 and slidably connected to the filter screen 2; and a round rod 32 fixedly installed on the bottom of the T-shaped rod 31 and slidably passing through the support plate 29.

[0048] In this embodiment, when the filter screen 2 vibrates, the T-shaped rod 31 is compressed, causing the buffer spring 30 to compress and store energy. During the reverse stroke, the spring force is released to assist in the reset. The round rod 32 passes through the support plate 29 to form a sliding pair, which restricts the T-shaped rod 31 to only make vertical movements and avoids lateral sway. When the filter screen 2 needs to be replaced, the box door 46 is opened, and the filter screen 2 is removed from the T-shaped rod 31 and the connecting rod 9 for cleaning or replacement. Through the effective buffering of the vibration of the filter screen 2 by the buffer mechanism, the filter screen 2 can always maintain a relatively stable working state, avoiding the deformation or blockage of the filter holes due to excessive vibration, thereby ensuring that the filtration device can continuously and stably provide a high-quality filtration effect.

[0049] In a further preferred embodiment of the present invention, an arc-shaped baffle 33 for protecting the exhaust pipe 5 is fixedly installed on one side of the support plate 29. The arc-shaped baffle 33 covers the exhaust pipe 5 to prevent slag from clogging the air holes of the exhaust pipe 5.

[0050] In this embodiment, the arc-shaped baffle 33 covers the exhaust pipe 5 with a semi-enclosed structure, protecting it when not in use and preventing it from contacting the exhaust pipe 5 during slag filtration. The arc-shaped baffle 33, with its semi-enclosed structure, covers the exhaust pipe 5 and forms an effective physical barrier during slag filtration, blocking most of the slag outside the exhaust pipe 5. This avoids slag directly contacting the vent of the exhaust pipe 5, reducing the possibility of slag entering the vent and causing blockage.

[0051] Since slag usually has a certain degree of hardness and sharp edges, direct contact with the exhaust pipe 5 may cause wear and scratches to its surface. The protective function of the arc-shaped baffle 33 can effectively reduce this wear, protect the integrity and sealing of the exhaust pipe 5, extend the service life of the exhaust pipe 5, and reduce the maintenance and replacement costs of the equipment.

[0052] In a further preferred embodiment of the present invention, an operating port for loading and unloading the filter screen 2 is provided on one side of the box body 1, a box door 46 is hinged in the operating port, and a feed hopper 47 is fixedly installed on the top of the box body 1.

[0053] In this embodiment, the operating port on one side of the housing provides a dedicated channel for the installation and removal of the filter screen 2, allowing operators to easily enter the housing 1 to replace the filter screen 2. When different production needs require the replacement of filter screens 2 with different pore sizes, there is no need for large-scale disassembly of the equipment. Simply open the housing door and use the operating port to quickly disassemble and install the filter screen 2, greatly reducing equipment downtime and improving production efficiency. Because different pore sizes of filter screens 2 can be easily replaced, this filtration device can flexibly adapt to various production scenarios and material filtration requirements. Whether processing coarse or fine particulate materials, efficient filtration can be achieved by selecting the appropriate filter screen 2, enhancing the versatility and adaptability of the equipment and saving equipment procurement costs for enterprises.

[0054] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments:

[0055] In another embodiment of the present invention, a limiting plate 34 for preventing uneven accumulation of slag on the conveyor belt 16 is fixedly installed inside the box 1, an electromagnetic chuck 35 for removing iron impurities from the slag is provided inside the box 1, and a sliding mechanism for driving the electromagnetic chuck 35 to move is provided on the box 1.

[0056] In this embodiment, the presence of the limiting plate 34 can effectively prevent uneven accumulation of slag on the conveyor belt 16. During the slag transport process, the limiting plate 34 performs a leveling operation to ensure that the slag layer thickness is uniform. A uniform slag layer is crucial for subsequent processing steps. Whether in filtration, sorting, or other processing stages, it can ensure that each part of the slag is subjected to the same processing conditions, thereby improving the overall processing quality and avoiding the problem of over- or under-processing of some slag due to uneven slag accumulation.

[0057] Meanwhile, the uniform slag layer provides excellent conditions for the electromagnetic chuck 35 to adsorb iron impurities. When the slag layer is of uniform thickness, the electromagnetic chuck 35 can more stably and comprehensively cover the slag surface, uniformly adsorb iron impurities, reduce adsorption dead zones caused by uneven slag accumulation, further improve the removal effect of iron impurities, and provide purer raw materials for the subsequent utilization or processing of slag.

[0058] In another embodiment of the present invention, the sliding mechanism includes: a fixed box 36 fixedly installed on one side of the housing 1; a one-way screw 37 rotatably installed inside the housing 1 for driving the electromagnetic chuck 35 to move horizontally, the one-way screw 37 extending into the fixed box 36 and rotatably connected to one side of the inner wall of the fixed box 36; a slider 38 threadedly sleeved on the one-way screw 37 and fixedly connected to the electromagnetic chuck 35; an arc-shaped plate 39 fixedly installed inside the housing 1 for guiding the slider 38, the arc-shaped plate 39 being slidably connected to the slider 38; a second discharge hopper 48 fixedly installed at the bottom of the fixed box 36 for discharging ferrous impurities; and a linkage mechanism disposed on the shaft of the one-way screw 37 and the first sprocket 22 for synchronously driving the one-way screw 37 and the first sprocket 22 to rotate.

[0059] In this embodiment, while the moving mechanism drives the scraper 20 to move, the sliding mechanism synchronously drives the electromagnetic chuck 35 to move through the linkage mechanism. When the one-way screw 37 rotates, the slider 38 slides along the guide rail of the arc plate 39, driving the electromagnetic chuck 35 to move horizontally from above the conveyor belt 16 into the fixed box 36. The curvature center of the arc plate 39 coincides with the axis of the one-way screw 37, ensuring smooth movement. After the electromagnetic chuck 35 moves into the fixed box 36, the electromagnetic chuck 35 is de-energized, and the material adsorbed on the electromagnetic chuck 35 is discharged through the second discharge hopper 48, completing the "adsorption-transfer-demagnetization" cycle. Through the setting of the linkage mechanism, the moving mechanism drives the scraper 20 to move and the sliding mechanism drives the electromagnetic chuck 35 to move synchronously. This synchronicity allows the various components to work together according to the predetermined logic and rhythm during the operation of the equipment, avoiding equipment failure or low processing efficiency caused by the uncoordinated actions of different components. For example, while the scraper 20 cleans the slag on the filter screen 2, the electromagnetic chuck 35 can also move into the fixed box 36 in a timely manner to discharge iron impurities, thereby improving the overall working efficiency of the equipment and the comprehensiveness of slag treatment.

[0060] In another embodiment of the present invention, the linkage mechanism includes: a rotating rod 40 rotatably mounted on the top of the fixed box 36; a second sprocket 41 respectively fixedly sleeved on one end of the rotating rod 40 and the one-way screw 37, and a third chain 42 sleeved on the two second sprockets 41; a third sprocket 43 respectively fixedly sleeved on the other end of the rotating rod 40 and the shaft of any first sprocket 22, and a fourth chain 44 sleeved on the two third sprockets 43; and a connecting cover 45 on the fixed box 36 and the housing 1 for protecting the third chain 42 and the fourth chain 44.

[0061] In this embodiment, when the second motor 21 drives the drum 7 to rotate, the first sprocket 22 shaft drives the rotating rod 40 to rotate via the third sprocket 43 and the fourth chain 44, and then drives the one-way screw 37 to rotate synchronously via the second sprocket 41 and the third chain 42. Through the setting of the linkage mechanism, when the second motor 21 drives the drum 7 to rotate, the first sprocket 22 shaft drives the rotating rod 40 to rotate via the third sprocket 43 and the fourth chain 44, and then drives the one-way screw 37 to rotate synchronously via the second sprocket 41 and the third chain 42. This multi-stage transmission method enables multiple components in the equipment to operate simultaneously, realizing the synchronous operation of the electromagnetic chuck 35 moving and the scraper 20 cleaning slag.

[0062] In summary, compared with related technologies, this device is beneficial for quickly and effectively removing fly ash and slag from fly ash and slag filter screens. It can also effectively reduce the probability of filter screen clogging, ensuring filtration effect and filtration speed, while reducing labor intensity, lowering operation difficulty, and improving work safety.
