Description

Technical Field

[0001] The present invention belongs to the field of environmental protection dust removal equipment, and particularly relates to a mixing and atomizing dust removal device for a solidification workshop. Background Art

[0002] Hazardous waste solidification is a technical method for treating hazardous waste, aiming to convert harmful substances in hazardous waste into forms that are not easily soluble, migratory, and diffusible, thereby reducing its harm to the environment and human health. After solidification treatment, hazardous waste can effectively reduce the leaching of harmful substances in hazardous waste, reduce the pollution risk to soil, water bodies, and air, and protect the ecological environment and human health. Moreover, the solidified hazardous waste has a more stable form and may have a reduced volume, which is convenient for transportation and storage, and also provides convenience for subsequent safe landfill or other disposal methods. Due to the large volume requirement for solidified hazardous waste treatment and the improvement of the standard for two indicators of water-soluble salts and organic matter in hazardous waste, it is necessary to mix and blend the hazardous waste such as received fly ash, slag, sediment, and sludge with single or multiple exceeded water-soluble salts or organic matter before landfill. For environmental protection reasons, the hazardous waste can be directly put into the mixing tank after unloading and mixed according to the blending plan. After mixing, the hazardous waste can be transferred to a turnover box and then to the solidification production line for solidification production, thereby improving production capacity and solving the short board of compliance disposal.

[0003] Currently, the general mixing method for hazardous waste to enter the material tank is to use an excavator for mixing. After mixing, the excavator grab is used to put it into the hoist of the solidification production line. Usually, high-pressure atomizing nozzles are installed equidistantly on the mixing tank. The high-pressure atomizing nozzles are used to spray the mixing range to achieve the purpose of dust reduction and removal. However, since the object processed by the high-pressure atomizing nozzles is hazardous waste, the hazardous waste often contains solid particles, impurities, or viscous substances. These substances may enter the small spray holes of the nozzles after being lifted, resulting in nozzle blockage, affecting the spray effect, and even causing the spray system to malfunction. Moreover, the hazardous waste contains water-soluble salts and other corrosive components. The high-pressure atomizing nozzles are in long-term contact with these corrosive substances, which will accelerate the corrosion and wear of the nozzles, shorten the service life of the nozzles, and the corrosion and wear of the nozzles may also cause problems such as uneven spraying and poor atomization effect. Secondly, the mixing tank has a large area, and the existing atomizing dust removal means achieve limited effects, and its atomizing dust removal technology needs to be improved.

[0035] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. For the convenience of narration, words such as "upper", "lower", "left", and "right" hereinafter only indicate the same direction as the upper, lower, left, and right directions of the accompanying drawings themselves, and do not limit the structure.

[0036] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0037] Embodiment, as Figures 1 - 13 shown, the mixing and atomizing dust removal device for the solidification workshop provided by the present invention includes a water supply pipeline network 1. The supply end of the water supply pipeline network 1 is provided with a water pump and a water storage tank. A plurality of valves 17 and pressure gauges are arranged on the water supply pipeline network 1. The spraying end of the water supply pipeline network 1 is provided with a plurality of high-pressure atomizing components 2 distributed at intervals. The valve 17 is used to control the on-off situation and flow rate of local positions of the water supply pipeline network 1. The pressure gauge is used to monitor the pressure of the water supply pipeline network 1. The specifications of the water pump are selected according to the specific pressure requirements of the water supply pipeline network 1, and the size of the mixing tank 9, that is, the actual mixing range of the excavator, needs to be considered. The preferred specifications of the water pump used in the present invention are as follows: head: 50 - 80 meters; working pressure: 0.4 - 0.6 MPa; 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 this device, the high-pressure atomization assembly 2 provided by the present invention includes a tee pipe 21 and a spray head 22 communicated with the tee pipe 21. A transition pipe 23 is threadedly connected between the tee pipe 21 and the spray head 22. A fluid guide 231 is arranged at the center of the transition pipe 23. A plurality of water injection channels 232 distributed in a circular array are arranged between the fluid guide 231 and the inner wall of the transition pipe 23. A buffer and pressure increasing member 24 extending towards the spray head 22 is arranged inside the transition pipe 23. A water injection cavity 25 communicated with the water injection channels 232 is arranged between the buffer and pressure increasing member 24 and the inner wall of the spray head 22. The buffer and pressure increasing member 24 is used to balance the fitting clearance between its front end and the water injection cavity 25. A plurality of spray holes 221 communicated with the water injection cavity 25 and distributed radially are arranged at the end of the spray head 22. A self-cleaning assembly 3 is arranged at a position of the tee pipe 21 opposite to the assembly direction of the spray head 22. The self-cleaning assembly 3 includes two symmetrically distributed self-cleaning pipes 31. The self-cleaning pipes 31 are communicated with the inside of the tee pipe 21 and extend towards the spray head 22. A servo adjustment mechanism 32 is arranged at a position of the self-cleaning assembly 3 close to 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. Two sealing members 33 connected to the spray head 22 are arranged at a position of the self-cleaning assembly 3 close to the water outlet end of the self-cleaning pipe 31. The sealing members 33 are used to seal the ports of the self-cleaning pipes 31.

[0039] Specifically, two branches of the tee pipe 21 are used to connect the conveying pipe network, and the other branch is used to install the transition pipe 23 and the spray head 22; the tee pipe 21, the transition pipe 23 and the spray head 22 are connected in a threaded and sealed manner with each other, which is convenient for disassembly and replacement; the clear water in the water conveying pipe network 1 enters from the fluid guide 231 and successively passes through the water injection channels 232, the water injection cavity 25 and the spray holes 221; the buffer and pressure increasing member 24 is installed in the transition pipe 23. On the one hand, it can compress the cross-sections of the water injection channels 232 and the water injection cavity 25, improve the pressure and flow rate of the clear water ejected, and is beneficial to forming a high-pressure fan-shaped spray; on the other hand, the buffer and pressure increasing member 24 has an axial advance and retreat margin, and can automatically buffer and give up a part of the clearance when the spray holes 221 are blocked, so as to balance the real-time ejection pressure, which is beneficial to flushing open the spray holes 221 with a tendency of blockage, is beneficial to reducing the probability of blockage of the spray holes 221, thus ensuring the uniformity of the spray and being beneficial to improving the atomization and dust removal effect.

[0040] Furthermore, the self-cleaning component 3 of the present invention can intermittently perform on-line flushing on the front end face of the nozzle 22. 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 can be deflected by a certain amplitude under drive, and the water pressure obtained from the water supply network 1 can hit the front end face of the nozzle 22. When the nozzle 22 is continuously atomizing and spraying, the self-cleaning pipes 31 intermittently spray clear water for flushing, which is beneficial to reducing the adhesion of salt blocks, reducing the probability of blockage and corrosion of the spray holes 221, ensuring the spray uniformity of the high-pressure atomization component 2, and thus improving the atomization dust removal effect. The spray outlet diameter of the self-cleaning pipe 31 is larger than the aperture of the spray holes 221 of the high-pressure atomization component 2, and the probability of its own blockage is much smaller than that of the spray holes 221 being blocked. Moreover, the self-cleaning component 3 uses a seal 33 to seal the self-cleaning pipes 31 after reset, which can ensure that the self-cleaning pipes 31 have 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, good dust removal effect, and high comprehensive utilization rate.

[0041] As Figure 9 、 Figure 11 and Figure 12 shown, in order to reduce the direct contact probability 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 one end away from the transition pipe 23. The end face of the nozzle 22 is an inner ring face 223 surrounded by the end plate 222. The cross section of the inner ring face 223 is V-shaped, and both sides of the V-shape are curved surfaces, and one of the curved surfaces penetrates the spray holes 221. Among them, the end plate 222 can surround all the spray holes 221 for nearly one circle, increasing the area for blocking the direct contact between the dust and the spray holes 221. However, the minimum inner diameter edge of the end plate 222 does not interfere with the spraying direction of the spray holes 221. Therefore, the clear 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] To ensure the mating performance between the self-cleaning pipe 31 and the front end of the nozzle 22, a pair of obliquely symmetrically distributed through holes 224 are provided on the end plate 222 of the present invention. The through holes 224 allow the end of the self-cleaning pipe 31 to pass through. One end of one through hole 224 intersects with the highest point of the end plate 222, and one end of the other through hole 224 intersects with the lowest point of the end plate 222. In this way, on the one hand, the through holes 224 constitute the maximum swing limit of the self-cleaning pipe 31 that mates with them, preventing the self-cleaning pipe 31 from disengaging from its working position; on the other hand, the widths of the two through holes 224 cause the two self-cleaning pipes 31 to form staggered spatial positions after swinging. In particular, the directions of the two cleaning sprays can face the inner ring surface 223, forming a relatively continuous water ring on the inner ring surface 223 for directly cleaning the water-soluble salts and other dust near the spray holes 221, and carrying the water-soluble salts and dust to be completely discharged from the lowest through hole 224, further ensuring the working performance of the nozzle 22.

[0043] As Figure 12 shown, to improve the mating performance between the seal 33 and the self-cleaning pipe 31, the seal 33 provided by the present invention includes a plug post 331. The plug post 331 is provided with a side port 332 at its position facing the self-cleaning pipe 31. One end of the side port 332 is a sealing inclined surface and is used to cooperate with the inclined surface provided at the end of the self-cleaning pipe 31. The other end of the side port 332 communicates with the end of the plug post 331. The cross-section of the side port 332 is U-shaped, and its U-shaped part is used to cooperate with the pipe surface of the self-cleaning pipe 31; for the self-cleaning pipe 31, a wedge 311 for sealing the side port 332 is provided on the side surface near its end. The end face of the wedge 311 is on the same inclined surface as the end face of the self-cleaning pipe 31. The self-cleaning pipe 31 is controlled by the servo adjustment mechanism 32 and can swing around its rotation center. The swinging movement at the end of the self-cleaning pipe 31 can cause it to insert into and slide out of the side port 332. If the self-cleaning pipe 31 slides out, its water spray direction is exactly facing the inner ring surface 223 of the nozzle 22. If the self-cleaning pipe 31 inserts into the side port 332, the end face of the self-cleaning pipe 31 can directly adhere to the sealing inclined surface, and its pipe surface and the wedge 311 can seal the U-shaped position of the side port 332, thereby achieving the sealing purpose. Therefore, through the sealing effect of the seal 33, the self-cleaning pipe 31 can have good sealing protection after reset, preventing the phenomenon of salt formation, and can perform effective cleaning operations after the self-cleaning pipe 31 disengages from the seal 33.

[0044] As 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 which 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 three-way 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, and 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, and a main rod section 244 located inside the water ejection chamber 25 is provided at one end of the reduced diameter rod section 243, and a conical head section 245 is provided at the end of the main rod section 244, 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, so as 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, and the spring 242 can form a certain shock wave at the moment of resetting, 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 Figures 4 - 8 As shown, in order to improve the practicality of the self-cleaning pipe 31, the self-cleaning pipe 31 provided by the present invention includes a transmission section 312 that is transmission-connected to the servo adjustment mechanism 32, and an L-shaped section 313 located outside the tee pipe 21 is provided at the end of the transmission section 312, and a telescopic section 314 is provided at the end of the L-shaped section 313, and a J-shaped section 315 is provided at the end of the telescopic section 314, and the J-shaped section 315 is bent and extended toward the end of the nozzle 22 and its end is inclined toward the sealing member 33. Among them, the transmission section 312 is used to obtain the power of swinging from the servo adjustment mechanism 32; the L-shaped section 313 is used to lengthen the vertical distance between the self-cleaning pipe 31 and the tee pipe 21, and provide a reasonable swing space for the swing of the self-cleaning pipe 31. In order to facilitate the replacement of the nozzle 22, the present invention designs a telescopic section 314 between the L-shaped section 313 and the J-shaped section 315, which can be tightly matched with one 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 and contract or rotate under the action of internal water pressure. Therefore, when it is necessary to replace 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 the nozzle 22 to be removed.

[0046] Furthermore, if Figure 5 As shown, the three-way pipe 21 is provided with a mounting protrusion 211 for mounting the servo adjustment mechanism 32, and the mounting protrusion 211 is provided with two water inlet holes 212 which are obliquely symmetrically distributed and used for mounting the self-cleaning pipe 31, and the water inlet holes 212 are tangent to the inner wall of the three-way pipe 21. In this way, the transmission section 312 obtains water flow from the water supply pipe network 1 through the water inlet holes 212, and the water flow can be accumulated from the L-shaped section 313, the telescopic end and the J-shaped section 315 to the ejection end in sequence, until the servo adjustment mechanism 32 drives the transmission section 312 to swing to fully open the ejection end, thereby realizing an 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 the spray end of the self-cleaning pipe 31 can be fully opened and directly correspond to its cleaning object after the end of the self-cleaning pipe 31 is adjusted to the maximum swing position, thereby 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 out, and the transmission sealing shell 321 is provided with a reduction gear group 322 inside, and the reduction gear group 322 includes a central gear shaft 3221, and two transition gears 3222 are symmetrically arranged on the transmission side of the central gear shaft 3221, and 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 sealing shell 321 is connected with the mounting protrusion 211 by bolts. Considering the space concentration, the mounting protrusion 211 and the two ends of the transmission sealing shell 321 can be designed to be narrower, so that the driven gear 3223 can be installed. The mounting surface corresponding to the servo motor 323 can be designed to be slightly larger, and it is also convenient to reasonably coordinate the assembly of the two transition gears 3222 and a central gear shaft 3221; the transmission sealing shell 321 is used as the assembly basis of the reduction gear set 322, and the corresponding shaft holes are set inside it for corresponding to the shaft ends of different gears, and the transmission sealing shell 321 is provided with bolt nodes connected with the servo motor 323. The servo motor 323 inputs power to the central gear shaft 3221, and the central gear shaft 3221 transmits the power to the transition gear 3222 and the driven gear 3223 in an orderly manner. The two driven gears 3223 drive the two self-cleaning pipes 31 to swing clockwise / counterclockwise, thereby enabling the servo motor 323 to realize the function of synchronously controlling the two self-cleaning pipes 31.

[0048] Considering that multiple mixing tanks 9 in the solidification workshop are generally arranged side by side, and in order to ensure that all mixing tanks 9 can obtain effective spraying through a set of water supply pipe networks 1, as Figures 1 - 3 shown, the water supply pipe network 1 includes a water inlet pipe 11 and a water return pipe 12 that are distributed parallel and opposite to the water inlet pipe 11. The two ends of the water return pipe 12 can be blocked by plugs and can be connected to the water supply system through other pipes to facilitate the recovery of clean water and better control the system pressure; an upper water pipe 13 and a lower water pipe 14 are arranged between the water inlet pipe 11 and the water return pipe 12, and a plurality of parallel pipes 15 are arranged between the upper water pipe 13 and the lower water pipe 14. Valves 17 are arranged on the water inlet pipe 11, the water return pipe 12, the parallel pipes 15, and the upper water pipe 13, and the high-pressure atomization assemblies 2 are all arranged on the lower water pipe 14. Among them, the interval distance between adjacent parallel pipes 15 can be designed as the length of one mixing tank 9, that is to say, the dust removal range of the high-pressure atomization assemblies 2 installed between adjacent parallel pipes 15 covers the area of one mixing tank 9. The water outlet pipe and the water pump pump water into the water supply pipe network 1 through the water inlet pipe 11. For the mixing materials that need dust removal, the corresponding pipelines can be opened by controlling the valves 17 of the parallel pipes 15 and the upper water pipe 13. In this way, not only can all mixing tanks 9 be dust-removed synchronously, but also targeted dust-removal operations can be carried out on individual mixing tanks 9, improving the water supply performance of the water supply pipe network 1.

[0049] In order to improve the atomization dust-removal performance of the present invention, both ends of the upper water pipe 13 provided by the present invention are connected to the water inlet pipe 11 and the water return pipe 12 through rotary joints 16. Spring mechanisms 4 are arranged on two parallel pipes 15 distributed close to the water inlet pipe 11 and the water return pipe 12. Rotary pull rods 5 are arranged at the connection positions of other parallel pipes 15 and the lower water pipe 14. A fixed groove 6 is arranged at the end of the rotary pull rod 5, and a lifting opening is arranged on the groove side of the fixed groove 6. Adjacent rotary pull rods 5 are connected by a lifting rod 81. The top end of the rotary pull rod 5 is rotationally matched with the parallel node of the lower water pipe and the parallel pipe, and its bottom end is rotationally matched with the lifting rod 81. A fork arm 7 is arranged on one side of the lifting rod 81, and a lifting adjustment mechanism 8 is arranged at the driving end of the fork arm 7. Among them, the lifting adjustment mechanism 8 preferably adopts a lead screw and slide plate mechanism, and only needs to be powered on to perform the lifting drive action without setting other pump sources; the lifting adjustment mechanism 8 drives the fork arm 7 to lift. If the fork arm 7 forks the lifting rod 81 to make a lifting action along the lifting opening, the rotary pull rod 5 can make a corresponding planar movement, and the rotary pull rod 5 can drive the upper water pipe 13, the lower water pipe 14, and the parallel pipes 15 to rotate around the center of the rotary joint 16, thereby driving the change of the spraying coverage area of all the high-pressure atomization assemblies 2, and further improving the atomization dust-removal performance of the equipment in the specific working environment. The present invention adopts a set of lifting adjustment mechanism 8 to simultaneously drive the action of multiple parallel nodes of the lower water pipe 14. Coupled with the balance support of the spring mechanism 4, it is beneficial to improve the stability of the water supply pipe network 1 during the action of the operating machinery.

[0050] As Figure 13 shown, the tension spring mechanism 4 provided by the present invention includes a tension spring 41. Rotating hinges 42 are provided at both ends of the tension spring 41. A hoop 43 that is rotationally engaged with the end of the rotating hinge 42 is provided at the end of the rotating hinge 42. A clamp 44 is provided inside the hoop 43. The inner side of the clamp 44 is tightly fitted with the water supply pipe network 1. A smooth surface groove 441 for the hoop to adaptively rotate is provided on the outer side of the clamp 44. Among them, the clamp 44 can maintain relative fixation with the pipe surface it is installed on by friction. If the hoop 43 and the clamp 44 are vertical installation nodes, their vertical height remains unchanged, but they can rotate around the clamp; at the same time, the tension spring 41 is connected to the two hoops 43 through the rotating hinges 42, and has rotating free ends in multiple directions in space. In this way, when the lifting adjustment mechanism 8 adjusts the dust removal range of the high-pressure atomization component 2, the tension spring mechanism 4 can be used as a set of support systems to ensure the balance of the orientation of the sewer pipe 14, and further ensure the dust removal performance of the high-pressure atomization component 2.
