Description

Technical Field

[0001] The invention belongs to the field of environmental protection dust removal equipment, and in particular relates to a material mixing atomization dust removal device for a stabilization workshop. Background Art

[0002] Hazardous waste stabilization is a technical method for treating hazardous waste, aiming to transform hazardous substances in the waste into a form that is less soluble, less mobile, and less diffusible, thereby reducing their risk to the environment and human health. Stabilization effectively reduces the leaching of hazardous substances from hazardous waste, lowering the risk of soil, water, and air pollution, thereby protecting the environment and human health. Furthermore, stabilized hazardous waste is more stable and potentially smaller, making it easier to transport and store, and facilitating subsequent safe landfill or other disposal methods. Due to the large volume of hazardous waste stabilization required and the stricter standards for water-soluble salts and organic matter in hazardous waste, stored fly ash, slag, sediment, sludge, and other hazardous wastes that exceed the standards for either single or multiple water-soluble salts or organic matter must be mixed and landfilled. For environmental reasons, hazardous waste can be directly transferred from unloaded trucks to a mixing tank for mixing according to a mixing plan. After mixing, the waste can be transferred to transfer containers and then to the stabilization production line for stabilization production, thereby increasing production capacity and addressing shortcomings in compliant disposal.

[0003] Currently, hazardous waste is typically mixed in the mixing tank using an excavator. After mixing, the excavator's grab bucket transfers the material to the stabilization line's hopper. High-pressure atomizing nozzles are typically installed at regular intervals above the mixing tank to spray the mixing area, thereby reducing dust. However, since these nozzles treat hazardous waste, which often contains solid particles, impurities, or sticky materials, these particles can enter the nozzle's tiny orifices after being lifted, causing blockage, affecting spray efficiency, or even causing the spray system to malfunction. Furthermore, hazardous waste contains water-soluble salts and other corrosive components. Long-term exposure to these corrosive substances can accelerate corrosion and wear of the nozzles, shortening their service life. This corrosion and wear can also lead to uneven spraying and poor atomization. Furthermore, the large area of ​​the mixing tank limits the effectiveness of existing atomization methods, and atomization technology needs to be improved. Summary of the Invention

[0035] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless they conflict. For the convenience of description, the words "upper", "lower", "left", and "right" appearing below only indicate the upper, lower, left, and right directions consistent with the drawings themselves and do not limit the structure.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Examples, such as Figures 1-13 As shown, the mixing atomization and dust removal device for the stabilization workshop provided by the present invention includes a water supply network 1, the supply end of the water supply network 1 is provided with a clean water pump and a water storage tank, a plurality of valves 17 and a pressure gauge are provided on the water supply network 1, and a plurality of spaced high-pressure atomization components 2 are provided at the discharge end of the water supply network 1. The valve 17 is used to control the on-off status and flow rate of a local position of the water supply network 1. The pressure gauge is used to monitor the pressure of the water supply network 1. The specifications of the clean water pump are selected according to the specific pressure requirements of the water supply network 1, and the size of the mixing tank 9, that is, the actual mixing range of the excavator, needs to be taken into account. The preferred specifications of the clean water pump used in the present invention are as follows: lift: 50-80 meters; working pressure: 0.4-0.6MPa; inlet diameter: DN40; material: stainless steel. The water storage tank adopts a horizontal PE tank with a volume of 10m 3 .

[0038] In order to improve the atomization and dust removal performance of the present invention, the high-pressure atomization assembly 2 provided by the present invention includes a three-way pipe 21 and a nozzle 22 connected to the three-way pipe 21, a transition pipe 23 is threadedly connected between the three-way pipe 21 and the nozzle 22, a guide body 231 is provided at the center of the transition pipe 23, a plurality of water injection channels 232 distributed in a circular array are provided between the guide body 231 and the inner wall of the transition pipe 23, a buffer pressure member 24 extending toward the nozzle 22 is provided inside the transition pipe 23, a water injection cavity 25 connected to the water injection channel 232 is provided between the buffer pressure member 24 and the inner wall of the nozzle 22, the buffer pressure member 24 is used to balance the fitting gap between its front end and the water injection cavity 25, and the end of the nozzle 22 A plurality of spray holes 221 connected to the water ejection chamber 25 and distributed radially are provided. The three-way pipe 21 is provided with a self-cleaning component 3 at a position opposite to the assembly direction of the nozzle 22. The self-cleaning component 3 includes two symmetrically distributed self-cleaning pipes 31. The self-cleaning pipes 31 are connected to the interior of the three-way pipe 21 and extend toward the nozzle 22. The self-cleaning component 3 is provided with a servo adjustment mechanism 32 near the water inlet end of the self-cleaning pipe 31. The servo adjustment mechanism 32 is used to adjust the rotation angle of the self-cleaning pipe 31. The self-cleaning component 3 is provided with two seals 33 connected to the nozzle 22 near the water outlet end of the self-cleaning pipe 31. The seals 33 are used to seal the port of the self-cleaning pipe 31.

[0039] Specifically, two branches of the tee pipe 21 are used to connect the delivery network, and the other branch is used to install the transition pipe 23 and the nozzle 22; the tee pipe 21, the transition pipe 23 and the nozzle 22 are connected to each other by threaded sealing, which is convenient for disassembly and replacement; the clean water in the water delivery network 1 enters from the guide body 231, and passes through the water injection channel 232, the water injection chamber 25 and the spray hole 221 in turn; a buffer pressure member 24 is installed in the transition pipe 23, which can compress the cross-section of the water injection channel 232 and the water injection chamber 25, increase the pressure and flow rate of the clean water sprayed, and is conducive to forming a high-pressure fan-shaped spray; on the other hand, the buffer pressure member 24 has an axial advance and retreat margin, which can automatically buffer and make room for a part of the gap when the spray hole 221 is blocked, so as to balance the real-time spraying pressure, which is conducive to flushing the spray hole 221 that has a tendency to be blocked, and is conducive to reducing the probability of blockage of the spray hole 221, thereby ensuring the uniformity of the spray and improving the atomization dust removal effect.

[0040] Furthermore, the present invention uses a self-cleaning assembly 3 to intermittently flush the front end face of the nozzle 22 online. For example, the servo adjustment mechanism 32 is used to provide servo power to the two self-cleaning pipes 31. The self-cleaning pipes 31 are driven to produce a certain degree of deflection. The water pressure obtained from the water supply network 1 can hit the front end face of the nozzle 22. When the nozzle 22 maintains continuous atomization and spraying, the self-cleaning pipe 31 intermittently sprays clean water for flushing, which is beneficial to reduce the adhesion of salt blocks and the probability of clogging and corrosion of the nozzle hole 221. It is beneficial to ensure the spray uniformity of the high-pressure atomization assembly 2, thereby improving the atomization and dust removal effect. The nozzle diameter of the self-cleaning pipe 31 is larger than the diameter of the nozzle hole 221 of the high-pressure atomization assembly 2. The probability of its own clogging is much lower than the probability of clogging of the nozzle hole 221. In addition, the self-cleaning assembly 3 uses a seal 33 to seal the self-cleaning pipe 31 after reset, which can ensure that the self-cleaning pipe 31 has a long maintenance-free working cycle and a reasonable service life. Therefore, the present invention has a self-cleaning function, is easy to maintain, has a long service life, has a good dust removal effect, and has a high comprehensive utilization rate.

[0041] like Figure 9 、 Figure 11 and Figure 12 As shown, to reduce the probability of direct contact between the spray holes 221 and the dust in the mixing area of ​​the workshop, the nozzle 22 provided by the present invention is provided with an annular end plate 222 at its end away from the transition pipe 23. The end face of the nozzle 22 is an inner annular surface 223 surrounded by the end plate 222. The cross-section of the inner annular surface 223 is V-shaped, and both sides of the V-shape are curved surfaces, one of which penetrates the spray holes 221. The end plate 222 can surround all the spray holes 221 by nearly a circle, increasing the area that blocks dust from directly contacting the spray holes 221. However, the minimum inner diameter edge of the end plate 222 does not interfere with the spray direction of the spray holes 221. Therefore, the clean water in the spray holes 221 can form an effective fan-shaped atomization range under high pressure, ensuring that the spray can fully contact the fly ash and dust in the mixing area.

[0042] In order to ensure the coordination between the self-cleaning tube 31 and the front end of the nozzle 22, the end plate 222 provided by the present invention is provided with a pair of obliquely symmetrically distributed through-holes 224. The through-holes 224 allow the ends of the self-cleaning tube 31 to pass through. One end of the through-hole 224 intersects the highest point of the end plate 222, while the other end of the through-hole 224 intersects the lowest point of the end plate 222. In this way, the through-holes 224, on the one hand, constitute a maximum swing limit for the self-cleaning tube 31 that cooperates with it, thereby preventing the self-cleaning tube 31 from deviating from its working position; on the other hand, the wide width of the two through-holes 224 allows the two self-cleaning tubes 31 to form an interlaced spatial position after swinging. In particular, the two cleaning spray directions can be directed toward the inner annular surface 223, forming a relatively continuous water ring on the inner annular surface 223, which is used to directly clean the water-soluble salts and other dust near the nozzle hole 221, and carry the water-soluble salts and dust to be discharged from the lowest through-hole 224, further ensuring the working performance of the nozzle 22.

[0043] like Figure 12 As shown, in order to improve the matching performance between the seal 33 and the self-cleaning tube 31, the seal 33 provided by the present invention includes a plug column 331, and the plug column 331 is provided with a side port 332 at a position facing the self-cleaning tube 31, one end of the side port 332 is a sealing slope and is used to match the slope provided at the end of the self-cleaning tube 31, and the other end of the side port 332 is connected with the end of the plug column 331, and the cross-section of the side port 332 is U-shaped and its U-shaped part is used to match the tube surface of the self-cleaning tube 31; for the self-cleaning tube 31, the self-cleaning tube 31 is provided with a wedge block 311 for sealing the side port 332 on the side near its end position, and the end face of the wedge block 311 is on the same slope as the end face of the self-cleaning tube 31. The self-cleaning tube 31 is controlled by the servo adjustment mechanism 32 to swing about its rotation center. The swinging movement of the end of the self-cleaning tube 31 allows it to be inserted into and removed from the side opening 332. If the self-cleaning tube 31 slides out, its water spray direction is directly toward the inner annular surface 223 of the nozzle 22. If the self-cleaning tube 31 is inserted into the side opening 332, the end face of the self-cleaning tube 31 can directly contact the sealing slope, and its tube surface and wedge 311 can seal the U-shaped position of the side opening 332, thereby achieving the purpose of sealing. Therefore, the sealing action of the seal 33 ensures that the self-cleaning tube 31 has better sealing protection after being reset, preventing salt accumulation. After the self-cleaning tube 31 is separated from the seal 33, it can perform effective cleaning operations.

[0044] like Figure 5As shown, in order to improve the atomization performance of the high-pressure atomization assembly 2, the buffer pressure member 24 provided by the present invention includes a piston head 241 that is nested and connected to one end of the flow guide 231. The side of the flow guide 231 facing the water inlet end of the tee pipe 21 is trumpet-shaped, and the side of the flow guide 231 facing the buffer pressure member 24 is provided with a blind hole. A spring 242 is provided between the piston head 241 and the blind hole of the flow guide 231. The piston head 241 is provided with a reduced diameter rod section 243 at the end facing away from the flow guide 231. One end of the reduced diameter rod section 243 is provided with a main rod section 244 located inside the water ejection chamber 25. The end of the main rod section 244 is provided with a conical head section 245, and the end of the water ejection chamber 25 opposite to the conical head section 245 is a conical surface with a different taper. Among them, a piston ring is provided on the side of the piston head 241, which cooperates with the blind hole of the guide body 231 to prevent water from entering the installation cavity where the spring 242 is located; the other end of the piston head 241 is used to compress the water injection cross-section, especially the water flow between the conical head section 245 and the water injection cavity 25 can form a dynamic equilibrium relationship with the spring 242; when the spray hole 221 is blocked, the reverse force received by the conical surface of the conical head section 245 increases and becomes uneven at some nodes, and the spring 242 produces an instantaneous compression and reset trend, and the water capacity of the conical head section 245 and the front end of the water injection cavity 25 increases. In addition, the spring 242 can form a certain shock wave at the moment of reset, which is conducive to opening the blocked position of the spray hole 221, and is conducive to ensuring the atomization uniformity of the high-pressure atomization component 2, thereby ensuring the atomization and dust removal effect of the present invention on fly ash and dust.

[0045] like Figure 4-Figure 8 As shown, to improve the practicality of the self-cleaning tube 31, the self-cleaning tube 31 provided by the present invention includes a transmission section 312 that is transmission-connected to the servo adjustment mechanism 32. The end of the transmission section 312 is provided with an L-shaped section 313 located outside the tee 21. The end of the L-shaped section 313 is provided with a telescopic section 314. The end of the telescopic section 314 is provided with a J-shaped section 315. The J-shaped section 315 bends and extends toward the end of the nozzle 22, and its end is inclined toward the seal 33. The transmission section 312 is used to obtain swinging power from the servo adjustment mechanism 32; the L-shaped section 313 is used to extend the vertical distance between the self-cleaning tube 31 and the tee 21, providing a reasonable swing space for the swing of the self-cleaning tube 31. In order to facilitate the removal and replacement of the nozzle 22, the present invention has designed a telescopic section 314 between the L-shaped section 313 and the J-shaped section 315, which can be tightly matched with either of the two. The telescopic section 314 can slide along the connection direction of the L-shaped section 313 and the J-shaped section 315 under the action of external force, and will not freely expand or rotate under the action of internal water pressure. Therefore, when it is necessary to remove the nozzle 22, the combined length of the L-shaped section 313, the telescopic section 314 and the J-shaped section 315 can be lengthened, and the J-shaped section 315 can be deflected at a small angle to make room for removing and installing the nozzle 22.

[0046] Further, if Figure 5 As shown, the tee pipe 21 is provided with a mounting block 211 for mounting the servo adjustment mechanism 32. The mounting block 211 is provided with two obliquely symmetrically distributed water inlet holes 212 for mounting the self-cleaning pipe 31. The water inlet holes 212 are tangent to the inner wall of the tee pipe 21. In this way, the transmission section 312 receives water from the water supply network 1 through the water inlet holes 212. The water is accumulated in sequence through the L-shaped section 313, the telescopic end, and the J-shaped section 315 to the discharge end, until the servo adjustment mechanism 32 drives the transmission section 312 to swing, causing the discharge end to fully open, thereby achieving effective online self-cleaning operation. If the water inlet hole 212 is tangent to the inner wall of the tee pipe 21, on the one hand, it is conducive to the automatic flow of water into the interior of the self-cleaning pipe 31, and on the other hand, it can make the transmission section 312 and the axis of the tee pipe 21 have a larger vertical span. The transmission section 312 serves as the rotation axis of the self-cleaning pipe 31. The larger vertical span ensures that after the end of the self-cleaning pipe 31 is adjusted to the maximum swing position, its spray end can be fully opened and directly correspond to its cleaning object, avoiding the inability to perform effective cleaning operations due to insufficient opening angle.

[0047] like Figure 8 As shown, in order to improve the synchronous control performance of the servo adjustment mechanism 32 on the two self-cleaning pipes 31, the servo adjustment mechanism 32 provided by the present invention includes a transmission sealing shell 321, and the transmission sealing shell 321 is provided with a through hole for the transmission section 312 to extend. A reduction gear group 322 is provided inside the transmission sealing shell 321, and the reduction gear group 322 includes a central gear shaft 3221. Two transition gears 3222 are symmetrically provided on the transmission side of the central gear shaft 3221. The transmission side of the transition gear 3222 is provided with a driven gear 3223 that is transmission-connected to the end of the self-cleaning pipe 31, and the power input end of the central gear shaft 3221 is provided with a servo motor 323 located outside the transmission sealing shell 321. The transmission seal housing 321 is connected to the mounting protrusion 211 by bolts. Considering space conservation, the mounting protrusion 211 and both ends of the transmission seal housing 321 can be designed to be narrower, allowing for the installation of the driven gear 3223. The mounting surface corresponding to the servo motor 323 can be designed slightly larger, which also facilitates the coordinated assembly of the two transition gears 3222 and the central pinion 3221. The transmission seal housing 321 serves as the assembly base for the reduction gear set 322. Corresponding shaft holes are provided within the transmission seal housing 321 for the shaft ends of the different gears. Furthermore, bolt nodes for connection to the servo motor 323 are provided on the transmission seal housing 321. The servo motor 323 inputs power to the central pinion 3221, which transmits the power in an orderly manner to the transition gear 3222 and the driven gear 3223. The two driven gears 3223 drive the two self-cleaning tubes 31 to swing clockwise / counterclockwise, thereby enabling the servo motor 323 to achieve synchronous control of the two self-cleaning tubes 31.

[0048] Considering that there are usually multiple mixing tanks 9 in the stabilization workshop, in order to ensure that all mixing tanks 9 can obtain effective spraying through a set of water pipe network 1, Figure 1-Figure 3 As shown, the water supply network 1 includes an inlet pipe 11 and a return pipe 12 parallel to and opposite to the inlet pipe 11. The return pipe 12 can be sealed at both ends by plugs and can be connected to the water supply system through other pipes to facilitate the recovery of clean water and better control of the system pressure; an upper water pipe 13 and a lower water pipe 14 are arranged between the inlet pipe 11 and the return pipe 12, and a plurality of parallel pipes 15 are arranged between the upper water pipe 13 and the lower water pipe 14. The inlet pipe 11, the return pipe 12, the parallel pipe 15 and the upper water pipe 13 are all provided with valves 17, and the high-pressure atomization components 2 are all arranged on the lower water pipe 14. Among them, the spacing distance between adjacent parallel pipes 15 can be designed to be the length of a mixing tank 9, that is, the dust removal range of the high-pressure atomization assembly 2 installed between adjacent parallel pipes 15 covers the area of ​​a mixing tank 9, and the outlet pipe and the clean water pump pump water into the water supply network 1 through the water inlet pipe 11. For mixing materials that require dust removal, the corresponding pipelines can be opened by controlling the valves 17 of the parallel pipes 15 and the water supply pipes 13. In this way, all mixing tanks 9 can be dusted synchronously, and targeted dust removal operations can be carried out on individual mixing tanks 9, thereby improving the water supply performance of the water supply network 1.

[0049] In order to improve the atomization dust removal performance of the present invention, the two ends of the water supply pipe 13 provided by the present invention are connected to the water inlet pipe 11 and the return pipe 12 through a rotary joint 16, and the two parallel pipes 15 distributed near the water inlet pipe 11 and the return pipe 12 are each provided with a tension spring mechanism 4, and the connection positions of the other parallel pipes 15 and the downpipe 14 are each provided with a rotating pull rod 5, and the end of the rotating pull rod 5 is provided with a fixed groove 6, and a lifting port is provided on the side of the fixed groove 6. Adjacent rotating pull rods 5 are connected by a lifting rod 81, and the top of the rotating pull rod 5 is rotationally matched with the parallel node of the downpipe and the parallel pipe, and its bottom end is rotationally matched with the lifting rod 81. A fork arm 7 is provided on one side of the lifting rod 81, and a lifting adjustment mechanism 8 is provided at the driving end of the fork arm 7. Among them, the lifting and adjusting mechanism 8 preferably adopts a screw slide mechanism, which can be lifted and lowered by simply connecting to electricity, without setting up other pump sources; the lifting and adjusting mechanism 8 drives the fork arm 7 to lift and lower, and when the fork arm 7 forks the lifting rod 81 and lifts and lowers along the lifting port, it can make the rotating pull rod 5 perform corresponding planar motion, and the rotating pull rod 5 can drive the water pipe 13, the water pipe 14 and the parallel pipe 15 to rotate around the center of the rotary joint 16, thereby driving the spray coverage area of ​​all high-pressure atomizing components 2 to change, thereby improving the atomization and dust removal performance of this equipment in a specific working environment. The present invention adopts a set of lifting and adjusting mechanisms 8 to simultaneously drive the actions of multiple parallel nodes of the water pipe 14, and the balancing support function of the tension spring mechanism 4 is conducive to improving the stability of the passive mechanical action of the water supply network 1.

[0050] like Figure 13 As shown, the tension spring mechanism 4 provided by the present invention includes a tension spring 41, and both ends of the tension spring 41 are provided with a rotary hinge 42, and the end of the rotary hinge 42 is provided with a clamp 43 that rotates with it, and a clamp 44 is provided on the inner side of the clamp 43. The inner side of the clamp 44 is tightly fitted with the water supply network 1, and the outer side of the clamp 44 is provided with a smooth groove 441 for the clamp to rotate adaptively. Among them, the clamp 44 can be kept relatively fixed to the pipe surface on which it is installed by friction, and if the clamp 43 and the clamp 44 are vertically installed nodes, their vertical height remains unchanged, but they can rotate around the clamp; at the same time, the tension spring 41 establishes a connection relationship with the two clamps 43 through the rotary hinge 42, and has a free end that rotates in multiple directions in space. In this way, when the lifting and adjusting mechanism 8 adjusts the dust removal range of the high-pressure atomization assembly 2, the tension spring mechanism 4 can serve as a support system to ensure the balance of the orientation of the sewer pipe 14, thereby ensuring the atomization and dust removal performance of the high-pressure atomization assembly 2.
