When the power is off, the multiple rotating plates will rotate and reset, so that the vent is closed, and the magnetic metal particle dust falling from the electromagnet will slide smoothly along the inclined surface of the guide plate to the ash outlet, and then be pushed out by the ash pushing plate.

DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] Reference Figure 1-Figure 11 The ash conveying equipment based on the spray drying tower wastewater evaporation treatment technology includes a body 1, which is divided into a processing chamber 3 and a water storage chamber 4 by a filter plate 2. The water storage chamber 4 is filled with water. An air intake channel is fixedly installed on the side wall of the body 1. The air intake channel includes two cylinders 5 and a rotating cylinder 6. The rotating cylinder 6 is located between the two cylinders 5, and both ends are respectively sealed and rotatably connected to the ends of the two cylinders 5. An air outlet pipe 7 is fixedly installed on the upper surface of the body 1, and the air outlet pipe 7 is connected to a bag dust collector (not shown).
[0020] The side wall of the machine body 1 is fixedly mounted with a mounting rod 8, and a slot is provided at one end of the mounting rod 8 located outside, and a water inlet pipe 9 connected to the slot is fixedly mounted at one end located in the water storage chamber 4, and a piston rod 10 is inserted into the slot in a sliding seal, and a water outlet pipe 11 is fixedly mounted on the surface of the mounting rod 8, and a plurality of branch pipes 12 are fixedly mounted on the top of the water outlet pipe 11, and the ends of the branch pipes 12 away from the water outlet pipe 11 are all inserted into the processing chamber 3, and a mist nozzle 13 is fixedly mounted thereon, and a single nozzle 13 is provided in each of the water inlet pipe 9 and the water outlet pipe 11. The one-way valve in the water inlet pipe 9 is connected in the direction from the water storage chamber 4 to the slot, and the one-way valve in the water outlet pipe 11 is connected in the direction from the slot to the branch pipe 12. A reciprocating screw 14 is installed on the side wall of the body 1 for horizontal rotation. A transmission wheel 15 is fixedly connected on the reciprocating screw 14 and the rotating cylinder 6. A transmission belt 16 is meshed and wound on the two transmission wheels 15. A rotating blade 17 is fixedly installed in the rotating cylinder 6. A slide plate 18 is threadedly connected on the reciprocating screw 14, and the slide plate 18 is fixedly connected to the piston rod 10.
[0021] The flue gas to be introduced into the bag filter is first introduced into the air inlet channel and then into the processing chamber 3. When the flue gas is introduced into the air inlet channel, the rotating blades 17 will drive the rotating cylinder 6 to rotate due to the high speed of the flue gas. At this time, under the transmission action of the two transmission wheels 15 and the transmission belt 16, the reciprocating screw 14 will also rotate, and the slide plate 18 threadedly sleeved on the reciprocating screw 14 will drive the piston rod 10 to move back and forth laterally. The space volume between the end of the piston rod 10 and the wall of the slide groove will continuously change from small to large and then from large to small. When the space volume becomes larger, When the pressure in the chute decreases, the water in the water storage chamber 4 will enter the chute from the water inlet pipe 9. When the volume of the space becomes smaller, the pressure in the chute increases, and the water in the chute will enter the multiple branch pipes 12 from the water outlet pipe 11, and finally be sprayed out in the treatment chamber 3 from the mist nozzle 13. The sprayed water will cause the fine metal particles in the flue gas to sink, and then the flue gas will enter the bag-type dust collector from the exhaust pipe 7, so as to achieve the effect of filtering the particulate dust in the machine body 1, thereby avoiding the large amount of metal particles in the flue gas, which may cause damage to the filter bag when it is directly passed into the bag-type dust collector.
[0022] The filter plate 2 can filter the sprayed water, and the filtered water will enter the water storage chamber 4 again, thereby achieving the effect of water recycling, and the sunken fine particles of dust will accumulate on the upper surface of the filter plate 2. At the same time, the spraying of water does not require an additional electric drive device, and no additional electric drive cost will be generated.
[0023] The side wall of the machine body 1 is provided with an ash delivery port 19 and a slide port 24 which are connected with the processing chamber 3. A mounting block is fixedly installed on the side wall of the machine body 1. A blocking plate 21 for blocking the ash delivery port 19 is fixedly installed on the lower surface of the mounting block through a spring rod 20. A through hole is provided on the side wall of the machine body 1 away from the ash delivery port 19. A slide rod 22 is slidably inserted in the through hole. An ash pushing plate 23 and a rectangular block are fixedly installed on both ends of the slide rod 22. The ash pushing plate 23 corresponds to the position of the ash delivery port 19, and the lower surface is in sliding contact with the upper surface of the filter plate 2. A U-shaped force-bearing rod 25 is fixedly installed on the upper surface of the blocking plate 21. The force-bearing rod 25 is vertically slidably arranged in the slide port 24, and an inclined surface 26 is provided on the bottom end located in the processing chamber 3. The inclined surface 26 corresponds to the side wall position of the ash pushing plate 23. The force-bearing rod 25 is fixedly installed with a sealing plate 3 2, the surface of the sealing plate 32 is in sliding sealing contact with the cavity wall of the processing chamber 3, and is used to cover the sliding port 24, the ash pusher 23 is controlled to move horizontally by an energizing mechanism, the energizing mechanism includes a magnetic block 27, two groups of coils 28 and an energizing spring 29, a rotating rod 30 is provided for horizontal rotation in the rotating cylinder 6, the rotating blade 17 is fixedly sleeved on the rotating rod 30, the magnetic block 27 is fixedly installed at one end of the rotating rod 30, an L-shaped rod 31 is symmetrically fixedly installed on the inner wall of the cylinder 5 close to the body 1, the two groups of coils 28 are respectively wound on the two L-shaped rods 31, the magnetic block 27 is located between the two groups of coils 28, an L-shaped support plate is fixedly installed on the side wall of the body 1, and the two ends of the energizing spring 29 are respectively fixedly connected to the surface of the support plate and the surface of the rectangular block, and are electrically connected to the two groups of coils 28 to form a complete current loop.
[0024] In the initial state, that is, when no smoke enters the machine body 1, the ash pushing plate 23 will be located at the ash delivery port 19 under the elastic potential energy of the energized spring 29, and the surface of the ash pushing plate 23 will be against the inclined surface 26 of the force-bearing rod 25. Under the action of the pressure, the force-bearing rod 25 will move the blocking plate 21 upward, and the blocking plate 21 will no longer cover the ash delivery port 19. The ash delivery port 19 will be in an open state, and the spring rod 20 will be in a contracted state at this time.
[0025] When the smoke enters the air inlet channel, the rotating blades 17 will rotate with the rotating cylinder 6, so that the rotating rod 30 will also rotate with the magnet 27, and a magnetic field will be generated between the two L-shaped rods 31. While the magnet 27 is rotating, the magnetic flux passing through the coil 28 per unit time changes, and the coil 28 will generate current. The energized spring 29 will contract when energized, thereby moving the sliding rod 22 and the ash pushing plate 23 away from the ash conveying port 19. The pressing force exerted by the ash pushing plate 23 on the force-bearing rod 25 disappears, and the force-bearing rod 25 and the sealing plate 21 will quickly move down and reset under the elastic potential energy of the spring rod 20, and the sealing plate 21 will cover the ash conveying port 19 to prevent smoke from slipping out of the ash conveying port 19.
[0026] When the flue gas no longer flows into the body 1, the rotating blade 17 stops rotating, the magnetic block 27 also stops rotating, the coil 28 no longer generates current, and the energized spring 29 is no longer energized, and will quickly stretch and recover, and the slide bar 22 and the ash pushing plate 23 will move toward the direction close to the ash delivery port 19. During the movement, the ash pushing plate 23 will push the fine particles of dust accumulated on the upper surface of the filter plate 2 to move together, until the ash pushing plate 23 moves to the side wall and the inclined surface 26 of the force-bearing rod 25, and under the pressure of the inclined surface 26, the force-bearing rod 25 will move up with the blocking plate 21, so that the ash delivery port 19 is in an open state, and then the fine particles of dust are pushed out from the ash delivery port 19, so as to achieve the effect of automatically cleaning the filtered fine particles of dust.
[0027] An electromagnet 33 is fixedly installed in the processing chamber 3, and a plurality of first vents 34 are provided on the surface of the electromagnet 33. The electromagnet 33 is connected in series with a current loop formed by two sets of coils 28 and an energized spring 29. A guide plate 35 is obliquely provided in the processing chamber 3, and the guide plate 35 is located between the filter plate 2 and the electromagnet 33. An ash outlet 36 is vertically provided on the surface of the guide plate 35 near the ash delivery port 19.
[0028] When the coil 28 is energized, the electromagnet 33 becomes magnetic, thereby being able to absorb some of the magnetic metal fine dust contained in the flue gas, thereby improving the effect of filtering the metal dust particles. The multiple first vents 34 are provided to allow the flue gas to pass smoothly. After power is cut off, the electromagnet 33 is no longer magnetic, and the metal dust particles adsorbed on the surface of the electromagnet 33 will fall off and slide down along the surface of the guide plate 35, falling from the ash outlet 36 to the upper surface of the filter plate 2 near the ash outlet 19, and finally being pushed out and cleaned by the ash pushing plate 23.
[0029] The surface of the guide plate 35 is provided with a plurality of second vents 37, a rotating shaft 38 is horizontally rotatably installed in the second vent 37, a rotating plate 39 is fixedly sleeved on the rotating shaft 38, one end of the rotating shaft 38 passes through the machine body 1, and a sprocket 40 is fixedly sleeved, a plurality of sprockets 40 are meshed and wound with chains 41, the sprockets 40 are connected to the machine body 1 through elastic components, the elastic components include a torsion spring 42 sleeved on the rotating shaft 38, the two ends of the torsion spring 42 are respectively fixedly connected to the sprocket 40 and the machine body 1, and the plurality of The rotating shaft 38 is controlled to rotate together through the transmission component, and the transmission component includes a rack rod 43 and a gear 44 fixedly sleeved on one of the rotating shafts 38. The rack rod 43 and the gear 44 are meshingly connected. A fixed plate is fixedly installed on the back of the body 1. The upper surface of the fixed plate is fixedly connected to the rack rod 43 through a telescopic rod 45. A magnetic block 46 is fixedly installed on the top of the rack rod 43. A rectangular opening is opened in the wall of the processing chamber 3, and the electromagnet 33 partially passes through the rectangular opening and corresponds to the position of the magnetic block 46.
[0030] When no smoke enters the body 1, the electromagnet 33 is not energized and has no magnetism, so the magnetic block 46 will not be attracted by the electromagnet 33, and the rack rod 43 will be at the lowest point. Under the transmission action of the gear 44, the plurality of sprocket wheels 40 and the chain 41, the plurality of rotating plates 39 will be parallel to the guide plate 35, and the plurality of second vents 37 will be closed. When smoke enters the body 1, the electromagnet 33 is energized to generate magnetism, and the magnetic block 46 will be attracted by the electromagnet 33. The upward magnetic attraction of the electromagnet 33 causes the rack rod 43 to move up. At this time, under the transmission action of the gear 44, multiple sprockets 40 and the chain 41, the multiple rotating plates 39 will rotate and will no longer be parallel to the guide plate 35, so that the multiple second air vents 37 are opened to facilitate the passage of flue gas into the processing chamber 3. At the same time, non-magnetic metal particle dust can also be dropped from the multiple second air vents 37 to the upper surface of the filter plate 2, so as to prevent the flue gas from only passing through the ash outlet 36 with low passing efficiency.
[0031] When no smoke enters the body 1, the magnetic block 46 will move downward rapidly under the elastic potential energy of the multiple torsion springs 42, and the multiple rotating plates 39 will also rotate rapidly to be parallel to the guide plate 35, and close the second air vent 37, so that the magnetic metal particle dust separated from the electromagnet 33 will slide down along the surface of the guide plate 35 to fall from the ash outlet 36 to the upper surface of the filter plate 2, and be smoothly pushed out by the ash pushing plate 23, so as to prevent the metal particle dust separated from the electromagnet 33 from falling from the second air vent 37 in the open state and accumulating on the upper surface of the filter plate 2, so that this part of the metal particle dust is not pushed out by the ash pushing plate 23 that has been reset.
[0032] In the present invention, the flue gas to be introduced into the bag filter is first introduced into the air inlet passage and then into the processing chamber 3. When the flue gas is introduced into the air inlet passage, the rotating blades 17 will rotate the rotating cylinder 6 due to the high speed of the flue gas. At this time, under the transmission action of the two transmission wheels 15 and the transmission belt 16, the reciprocating screw 14 will also rotate. The slide plate 18 threadedly sleeved on the reciprocating screw 14 will carry the piston rod 10 to move back and forth laterally. The space volume between the end of the piston rod 10 and the wall of the slide groove will continuously change from small to large and then from large to small. When the space volume becomes larger, At this time, the pressure in the chute decreases, and the water in the water storage chamber 4 will enter the chute from the water inlet pipe 9. When the space volume becomes smaller, the pressure in the chute increases, and the water in the chute will enter the multiple branch pipes 12 from the water outlet pipe 11, and finally be sprayed out in the treatment chamber 3 from the mist nozzle 13. The sprayed water will cause the fine metal particles in the flue gas to sink, and then the flue gas will enter the bag-type dust collector from the air outlet pipe 7, and the effect of filtering the particulate dust will be achieved in the machine body 1, avoiding the metal particles in the flue gas. The dust is too much, which causes damage to the filter bag when it is directly passed into the bag-type dust collector.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
