Description

Technical Field

[0001] The invention relates to the technical field of fly ash treatment, in particular to a fly ash water washing leachate particle collection system. Background Art

[0002] Fly ash refers to tiny ash particles produced during the combustion of fuels (such as coal and domestic waste). Its particle size generally ranges from 1 to 100 μm. Conventional methods for handling fly ash include safe landfill and solidification stabilization.

[0003] In the process of treating fly ash, it is necessary to fully dissolve the fly ash in water so that the soluble substances can be dissolved in water. However, after the fly ash enters the water, the water-insoluble particles will form a large amount of sludge and deposit at the bottom of the equipment, affecting the full contact between the soluble substances and the water. Therefore, when obtaining the leached particles, it is easy to mix the water-soluble substances into the water-insoluble particles, affecting the purity of the obtained leached particles and the subsequent treatment process of the leached particles.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a fly ash washing leachate particle collection system, which has the following beneficial effects:

[0016] 1. The fly ash water washing leachate particle collection system feeds fly ash into the kettle from the feed port. The second motor drives the drive shaft to rotate, and the meshing action of the first bevel gear and the second bevel gear drives the rotating pipe to rotate. The U-shaped rod, inclined plate and scraper rotate synchronously with the rotating pipe to stir the inside of the kettle, and the scraper scrapes the inner wall of the kettle. During the rotation of the drive shaft, the air guide pipe, grille and shovel plate are driven to rotate, and the shovel plate turns over the sludge on the inner wall of the funnel.

[0017] 2. The fly ash washing leachate particle collection system drives the rotating shaft to rotate through a motor, which drives the spiral blades to rotate. The spiral blades push the sludge inside the sludge storage part into the sludge discharge barrel, and gradually increase the squeezing force on the sludge by reducing the pitch of the spiral blades, so that the excess water in the sludge passes through the filter holes and the filter screen and is discharged. Finally, the sludge is discharged through the sludge outlet, thereby achieving the purpose of preliminarily removing excess water in the sludge while discharging the sludge.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 2 A fly ash washing leachate particle collection system includes a reactor 100, which includes a reactor body 101. A funnel portion 102 is integrally formed at the bottom of the reactor body 101, a sludge storage portion 103 is integrally formed at the bottom of the funnel portion 102, and a feeding port 104 is fixedly installed on the top of the reactor body 101. The feeding port 104 is used to allow fly ash to pass into the reactor body 101. The funnel portion 102 is used to gather sludge so that the sludge tends to move toward the sludge storage portion 103. A sludge discharge assembly 200 is provided on the left side of the sludge storage portion 103, a stirring assembly 300 is provided inside the reactor body 101, a sludge turning assembly 400 is attached to the inner wall of the funnel portion 102, and an aeration assembly 500 is fixedly installed at the bottom of the sludge storage portion 103.

[0027] See also Figure 2-Figure 3The mud discharge assembly 200 includes a mud discharge barrel 201 welded to the left side of the mud storage section 103. The mud discharge barrel 201 is connected to the mud storage section 103. A mud outlet 202 is provided at the bottom of the left end of the mud discharge barrel 201 for discharging mud. A filter hole 203 is provided in an array throughout the left half of the mud discharge barrel 201. A filter screen 204 is provided on the outer side of the left half of the mud discharge barrel 201. A motor 205 is fixedly mounted on the left end of the mud discharge barrel 201. A rotating shaft 206 is fixedly mounted on the output end of the motor 205. The rotating shaft 206 is arranged along the axis of the mud discharge barrel 201. The right end of the rotating shaft 206 extends into the interior of the mud storage section 103. A spiral blade 207 is fixedly mounted on the surface of the rotating shaft 206.

[0028] The pitch of rotating shaft 206 gradually decreases from right to left, and the left end of rotating shaft 206 is flush with the right side wall of mud outlet 202. Motor 1 205 drives rotating shaft 206, driving spiral blade 207 to rotate. This causes the sludge inside mud storage section 103 to move leftward along mud discharge barrel 201 under the action of spiral blade 207. As spiral blade 207 pushes the sludge, its pitch gradually decreases, increasing the squeezing force on the sludge, squeezing out excess water from the sludge, and blocking the sludge through filter screen 204. Finally, the sludge is discharged from mud outlet 202.

[0029] See also Figure 2-Figure 5 The stirring assembly 300 includes a bracket 301 fixedly mounted on the top of the kettle body 101. A second motor 302 is fixedly mounted on the top of the bracket 301. A drive shaft 303 is fixedly mounted on the output end of the second motor 302. The drive shaft 303 extends through the reactor 100 and is rotatably connected to the reactor 100, extending along the axis of the reactor 100. A rotating tube 304 is sleeved around the drive shaft 303 and extends through the center of the top of the reactor body 101. Bevel gear 1 305 is fixedly mounted on both the top of the rotating tube 304 and the circumference of the drive shaft 303. Both bevel gears 1 305 are located within the bracket 301. A second bevel gear 306 meshes between the two bevel gears 1 305 and is rotatably connected to the top of the reactor body 101. The transmission action of the second bevel gear 306 causes the two bevel gears 1 305 to rotate in opposite directions, thereby causing the drive shaft 303 and the rotating tube 304 to rotate in opposite directions. The rotating tube 304 is located on the circumferential surface inside the kettle body 101 and is fixed with U-shaped rods 307 in an array. The inner side of the U-shaped rods 307 is fixed with inclined plates 308. When the rotating tube 304 rotates, the U-shaped rods 307 and inclined plates 308 are driven to stir the water inside the kettle body 101, promoting the integration of fly ash into the water.

[0030] A scraper blade 309 is fixedly mounted on the side of the U-shaped rod 307 away from the rotating tube 304. The scraper blade 309 is attached to the side wall of the kettle body 101, with its ends respectively attached to the top wall of the kettle body 101 and the inner edge of the funnel portion 102. Therefore, during the rotation of the rotating tube 304 and the U-shaped rod 307, the scraper blade 309 scrapes the side wall of the kettle body 101, preventing sludge from adhering to the side wall of the kettle body 101.

[0031] See also Figure 4-Figure 5 The mud turning assembly 400 includes an array of air ducts 401 fixed to the lower half of the drive shaft 303. The air ducts 401 are parallel to the inner wall of the funnel 102. A grille 402 is fixedly mounted at the bottom of the grille 402. A shovel plate 403 is also fixedly mounted at the bottom of the grille 402. The shovel plate 403 is attached to the inner wall of the funnel 102. When the drive shaft 303 rotates, the air ducts 401 rotate synchronously, driving the shovel plate 403 to scrape the inner wall of the funnel 102, promoting mud turning. The grille 402 allows mud to pass through it, preventing excessive mud from accumulating in front of the grille 402 and shovel plate 403, which would otherwise create significant resistance during the rotation of the air ducts 401, grille 402, and shovel plate 403.

[0032] See also Figure 2-Figure 5 The aeration assembly 500 includes an air box 501 fixedly mounted at the bottom of the mud storage section 103. An aeration fan 502 is connected to the side of the air box 501 via a pipe. A drive shaft 303 extends through and rotatably connects to the center of the air box 501. A columnar cavity 503 is provided within the lower half of the drive shaft 303, communicating with the air duct 401. A through-hole 504 is formed in an array along the surface of the drive shaft 303, communicating with the air box 501 through the through-hole 504. Aeration nozzles 505 are arranged in an array along the length of the top of the air duct 401, communicating with the air duct 401. Thus, air is ventilated into the air box 501 via the aeration fan 502. Air then passes through the through-hole 504 and enters the columnar cavity 503. The air then passes through the air duct 401 and is ejected from the aeration nozzles 505, achieving aeration.

[0033] During use, fly ash is fed into the kettle body 101 from the feeding port 104, and the drive shaft 303 is driven to rotate by the second motor 302, which cooperates with the meshing action of the first bevel gear 305 and the second bevel gear 306, thereby driving the rotating tube 304 to rotate. The U-shaped rod 307, the inclined plate 308 and the scraper 309 rotate synchronously with the rotating tube 304, stirring the interior of the kettle body 101, and the scraper 309 scrapes the inner wall of the kettle body 101;

[0034] During the rotation of the drive shaft 303, the air guide pipe 401, the grille 402 and the shovel plate 403 are driven to rotate, and the shovel plate 403 turns over the sludge on the inner wall of the funnel 102; at the same time, the aeration fan 502 introduces air into the air storage box 501, and the air is then ejected upward through the aeration nozzle 505 for aeration;

[0035] The motor 205 drives the rotating shaft 206 to rotate, driving the spiral blade 207 to rotate, so that the spiral blade 207 pushes the sludge inside the mud storage part 103 into the mud discharge barrel 201, and the pitch of the spiral blade 207 is reduced, gradually increasing the squeezing force on the sludge, so that the excess water in the sludge passes through the filter hole 203 and the filter screen 204 and is discharged. Finally, the sludge is discharged through the mud outlet 202.
