Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a clamping structure and wet high-voltage electrostatic dust removal equipment. Background Art

[0002] In modern industrial production and environmental protection, the effective removal of particulate matter from exhaust gases has always been a major issue. With the rapid development of industry, particulate matter in exhaust emissions poses a serious threat to the environment and human health. Traditional dust removal technologies, such as mechanical dust removal and filtration dust removal, are often ineffective when dealing with fine particulate matter. To more efficiently capture fine particulate matter, electrostatic dust removal technology has emerged. The principle of electrostatic dust removal is to use a high-voltage electric field to ionize the gas, generating a large number of electrons and ions, which charge the particulate matter and then trap it under the action of the electric field force. Under certain special operating conditions, such as when treating exhaust gases containing corrosive components, the internal equipment materials may be damaged by prolonged gas corrosion and require repair or replacement. For example, when replacing the cathode plate in the prior art wet high-voltage electrostatic precipitator, because the cathode plate crosses the entire anode tube, workers need to climb back and forth between the two ends of the anode tube to remove the cathode plate. This increases the safety risk for workers. In view of this, the present application proposes a clamping structure and wet high-voltage electrostatic precipitator. Utility Model Content

[0044] As Figures 1 to 14As shown, in one embodiment, a clamping structure 20 for clamping a cathode sheet 50 includes a support assembly 21 including an upper hanger 211 and a lower hanger 212, the upper hanger 211 and the lower hanger 212 being spaced apart along a vertical direction, a hanging assembly 22 including an embedding block 221, a hanging block 222, and an anti-disengaging block 223, the embedding block 221 being arranged at one end of the cathode sheet 50, the hanging block 222 being arranged on the upper hanger 211, the hanging block 222 being provided with a sliding groove, the anti-disengaging block 223 being rotatably arranged on the hanging block 222, the embedding block 221 being slid into the sliding groove, and the anti-disengaging block 223 being in abutment with the embedding block 221, so as to clamp the embedding block 221 and the hanging block 222, a clamping assembly 23 including a taper joint 231, an inverse taper block 232, and a claw base 233, the claw base 233 being arranged on the lower hanger 212, the taper joint 231 being arranged at an end of the cathode sheet 50 away from the embedding block 221, the inverse taper block 232 being sleeved on the taper joint 231, and the taper joint 231 being inserted into the claw base 233, so as to clamp the taper joint 231 by the claw base 233, and the taper joint 231 driving the inverse taper block 232 to be inserted into the claw base 233, so as to release the taper joint 231 by the claw base 233.

[0045] It should be noted that the box frame 10 is provided with an upper box body 11, a middle box body 12, and a lower box body 13, the middle box body 12 being located between the upper box body 11 and the lower box body 13, and both ends of the middle box body 12 being in communication with the upper box body 11 and the lower box body 13, a plurality of upper insulating columns 121 being arranged in the upper box body 11, and a plurality of lower insulating columns 131 being arranged in the lower box body 13, each of the upper insulating columns 121 being connected with the upper hanger 211, and each of the lower insulating columns 131 being connected with the lower hanger 212, so that the upper hanger 211 is located in the upper box body 11, and the lower hanger 212 is located in the lower box body 13. Further, the hanging block 222 is arranged on the upper hanger 211, and the hanging block 222 is located on a side of the upper hanger 211 facing the lower hanger 212. The sliding groove is arranged on any three faces of the hanging block 222, and the protrusions are arranged on any three faces of the embedding block 221 parallel to the cathode sheet 50, the protrusions of the embedding block 221 being capable of sliding into the sliding groove of the hanging block 222, so that the embedding block 221 can be fixed on the upper hanger 211. Further, the fixing holes are arranged at both ends of the cathode sheet 50, and the protruding column is arranged at an end of the embedding block 221 away from the protrusions, so that the fixing hole at one end of the cathode sheet 50 is sleeved with the protruding column, and the cathode sheet 50 can be hung on the upper hanger 211.

[0046] As Figure 2As shown, in one embodiment, the side of the hanging block 222 without the sliding groove is provided with an opening, so that the embedded block 221 can slide into the hanging block 222 from the opening. Furthermore, one end of the anti-slip block 223 is rotatably set on the hanging block 222, and the anti-slip block 223 is located on one side of the opening of the hanging block 222, and the other end of the anti-slip block 223 can be rotated to the opening of the hanging block 222. When the embedded block 221 slides into the hanging block 222, the other end of the anti-slip block 223 rotates downward due to the action of gravity, so that the other end of the anti-slip block 223 is located at the opening of the hanging block 222 and abuts against the embedded block 221. In this way, the embedded block 221 and the hanging block 222 are clamped, and the embedded block 221 cannot slide out of the opening of the hanging block 222.

[0047] like Figure 2 As shown, in one embodiment, the hanging assembly 22 further includes a pressing block 224 . The pressing block 224 is disposed on the embedding block 221 . The pressing block 224 and the embedding block 221 jointly fix the cathode sheet 50 .

[0048] It should be noted that the pressure block 224 is arranged on the embedded block 221. For example, the pressure block 224 is screwed to the embedded block 221 by screws, and the boss is located between the embedded block 221 and the pressure block 224. When the fixing hole on the cathode sheet 50 is engaged with the boss on the embedded block 221, the cathode sheet 50 is located between the embedded block 221 and the pressure block 224, and the embedded block 221 and the pressure block 224 jointly clamp the cathode sheet 50.

[0049] like Figures 6 to 13 As shown, in one embodiment, the conical joint 231 includes a column 2311 and a conical cap 2312. The column 2311 is arranged at the end of the cathode plate 50 away from the embedded block 221, and the conical cap 2312 is arranged at the end of the column 2311 away from the cathode plate 50. The conical cap 2312 is clamped with the claw seat 233.

[0050] It should be noted that the cone cap 2312 is a conical structure, and the side with the largest diameter of the cone cap 2312 is set at the end of the column 2311 away from the cathode plate 50, so that the side with the smallest diameter of the cone cap 2312 is further away from the cathode plate 50, so that when the cone cap 2312 is engaged with the claw seat 233, the side with the smallest diameter of the cone cap 2312 will first contact the claw seat 233. Furthermore, the anti-cone block 232 is also a conical structure, and the anti-cone block 232 is sleeved on the column 2311, and the side with the largest diameter of the anti-cone block 232 faces the side with the largest diameter of the cone cap 2312. It should be noted that the maximum diameter of the anti-cone block 232 is greater than the maximum diameter of the cone cap 2312. When the column 2311 faces the claw seat 233, the anti-cone block 232 will also slide down along the column 2311 under the action of gravity and fit into the cone cap 2312. When the column 2311 faces the claw seat 233, the anti-cone block 232 will slide down along the column 2311 under the action of gravity and fit into the cone cap 2312. When the body 2311 pushes the cone cap 2312 to be plugged into the claw seat 233, since the maximum diameter of the anti-cone block 232 is larger than the maximum diameter of the cone cap 2312, the claw seat 233 pushes the anti-cone block 232 to slide upward relative to the cone cap 2312, so that the anti-cone block 232 stops outside the claw seat 233 and cannot follow the cone cap 2312 to be plugged into the claw seat 233. In this way, the claw seat 233 clamps the cone cap 2312, so that the cathode plate 50 is fixed on the lower frame 212.

[0051] like Figures 6 to 13 As shown, in one embodiment, a convex ring 23111 is provided on the column 2311 , and the convex ring 23111 is used to push the anti-cone block 232 so that the anti-cone block 232 is inserted into the claw seat 233 .

[0052] It should be noted that the convex ring 23111 is set at the end of the column 2311 close to the cathode plate 50, so that the anti-cone block 232 has a sliding distance between the cone cap 2312 and the convex ring 23111. When the column 2311 pushes the cone cap 2312 into the claw seat 233, the anti-cone block 232 is pushed up by the claw seat 233 so that the anti-cone block 232 is parked outside the claw seat 233, and the sliding distance between the side of the smallest diameter of the anti-cone block 232 and the convex ring 23111 is the largest. When the column 2311 continues to When the cone cap 2312 is continuously pushed deeper into the claw seat 233, the convex ring 23111 will follow the column 2311 close to the anti-cone block 232, so that the distance between the convex ring 23111 and the anti-cone block 232 slowly decreases. When the convex ring 23111 and the anti-cone block 232 fit together, the convex ring 23111 will push the anti-cone block 232 to abut against the claw seat 233. Under the continuous pushing of the convex ring 23111, the anti-cone block 232 will be inserted into the claw seat 233. At this time, the anti-cone block 232 and the cone cap 2312 are both located in the claw seat 233. Furthermore, because the side with the largest diameter of the inverted cone block 232 abuts against the side with the largest diameter of the cone cap 2312, the smallest diameter surfaces of the inverted cone block 232 and the cone cap 2312 face opposite directions. When the column 2311 drives the cone cap 2312 to withdraw from the claw seat 233, the inverted cone block 232 first abuts against the claw seat 233, thereby driving the cone cap 2312 to withdraw from the claw seat 233. This disconnects the cathode plate 50 from the lower frame 212.

[0053] like Figures 6 to 13 As shown, in one embodiment, the claw seat 233 includes a bottom block 2331, a plurality of support blocks 2332 and a plurality of hook blocks 2333, the bottom block 2331 is arranged on the lower frame 212, and each support block 2332 is arranged on the bottom block 2331, and each support block 2332 is distributed along the circumference of the bottom block 2331, each hook block 2333 is rotatably arranged on each support block 2332, and each hook block 2333 corresponds to each support block 2332 one by one, and each hook block 2333 is used to jointly clamp the cone cap 2312, and each hook block 2333 is provided with an oblique angle portion 23331, and the cone cap 2312 is used to push up each oblique angle portion 23331.

[0054] It should be noted that the bottom block 2331 is a cylindrical, flat structure. Each support block 2332 is disposed on the side of the bottom block 2331 facing the cathode sheet 50, and each support block 2332 is distributed along the circumference of the bottom block 2331. Each support block 2332 has a connection hole on the end facing the cathode sheet 50, and each hook block 2333 is rotatably connected to each connection hole. Furthermore, each hook block 2333 is rotatably mounted on each support block 2332, and each hook block 2333 is located outside each circumferentially distributed support block 2332, so that each hook block 2333 wraps around each support block 2332. Each hook block 2333 is provided with a rotating post, which is sleeved with each connection hole, and each rotating post corresponds to a connection hole. This ensures that the hook blocks 2333 and the support blocks 2332 are distributed in the same manner, all around the circumference of the bottom block 2331.

[0055] like Figures 7 to 13 As shown, in one embodiment, each hook block 2333 is provided with an oblique portion 23331 toward the axial direction of the bottom block 2331, and the oblique portion 23331 is formed by an inclined surface and a right-angled surface to form a right-angled triangle structure, and the inclined surface of each oblique portion 23331 faces the cathode line. Since each hook block 2333 is distributed along the circumference of the bottom block 2331, and each oblique portion 23331 faces the axial direction of the bottom block 2331, each oblique surface forms a conical contact surface with the axis of the bottom block 2331 as the center. The right-angled surfaces form a plane with the axis of the bottom block 2331 as the center. In this way, when the cone cap 2312 is plugged into the claw seat 233, the inclined surface between the minimum diameter and the maximum diameter of the cone cap 2312 will abut against the conical contact surface formed by the inclined surfaces. Under the continuous push of the column 2311, the inclined surface of the cone cap 2312 will push the conical contact surface formed by the inclined surfaces to open the inclined surfaces, so that the beveled portions 23331 are respectively opened outward with the axis of the bottom block 2331 as the center, so that the column 2311 can push the cone cap 2312 into the claw seat 233.

[0056] like Figures 6 to 13As shown, in an embodiment, the locking assembly 23 further comprises a plurality of elastic members 234, each of which is in the form of a spring and is arranged on the end of each support block 2332 away from the connecting hole, and each of which faces each hook-shaped block 2333 and abuts against the end of each hook-shaped block 2333 away from the bevel 23331, and each of which corresponds to each hook-shaped block 2333. In this way, when the conical cap 2312 is not in abutment with each bevel surface, each elastic member 234 will push each hook-shaped block 2333 to gather towards the axis of the bottom block 2331, so that the conical contact surface formed by the bevels is formed. When the column body 2311 pushes the conical cap 2312 to be inserted into the claw seat 233, the bevels of the conical cap 2312 will continuously push the conical contact surface formed by the bevels, so that each bevel 23331 is simultaneously spread outward with the axis of the bottom block 2331 as the center, and each hook-shaped block 2333 is pressed against the elastic member 234 on each support block 2332, so that the conical cap 2312 can be slidably inserted into the claw seat 233. When the maximum diameter surface of the conical cap 2312 slides through each bevel, the conical cap 2312 has entered the claw seat 233 at this time, and since the conical cap 2312 is arranged on the column body 2311, under the pushing of each elastic member 234, each hook-shaped block 2333 will drive each bevel 23331 to collectively move towards the column body 2311, so that the right-angled surface on each bevel 23331 abuts against the maximum diameter surface of the conical cap 2312, so that the conical cap 2312 cannot be pulled out after being inserted into the claw seat 233, thereby fixing one end of the cathode sheet 50 to the lower frame 212.

[0057] As shown, Figures 6 to 11 In an embodiment, the reverse conical block 232 is sleeved on the column body 2311, and under the action of gravity, the maximum diameter surface of the reverse conical block 232 will slide downward and fit the maximum diameter surface of the conical cap 2312. When the column body 2311 pushes the conical cap 2312 to abut against each bevel, under the action of each elastic member 234, the conical cap 2312 pushes each bevel 23331, and each bevel 23331 moves along the minimum diameter surface of the conical cap 2312 to the maximum diameter surface of the conical cap 2312, so that each bevel 23331 is spread outward by the conical cap 2312. When each bevel 23331 moves to the maximum diameter surface of the conical cap 2312, since the maximum diameter surface of the reverse conical block 232 fits the maximum diameter surface of the conical cap 2312, and the maximum diameter surface of the reverse conical block 232 is larger than the maximum diameter surface of the conical cap 2312, when the conical cap 2312 slides through each bevel 23331, under the action of each elastic member 234, each bevel 23331 will simultaneously gather towards the axis of the bottom block 2331, so that the reverse conical block 232 is stopped on the bevel of each bevel 23331.

[0058] As shown, Figures 9 to 11As shown, in one embodiment, when the cylinder 2311 continues to push the cone cap 2312 deeper into the claw seat 233, the convex ring 23111 will follow the cylinder 2311 close to the anti-cone block 232, so that the distance between the convex ring 23111 and the anti-cone block 232 slowly decreases. When the convex ring 23111 is in contact with the anti-cone block 232, the convex ring 23111 will push the largest diameter surface of the anti-cone block 232 to abut against each inclined surface. Under the continuous pushing of the cylinder 2311, each inclined surface is stretched outward to allow the anti-cone block 232 to slide into the claw seat 233.

[0059] like Figures 12 to 13 As shown, in one embodiment, when the column 2311 drives the cone cap 2312 to pull out the claw seat 233, since the anti-cone block 232 and the cone cap 2312 are both located in the claw seat 233, and the anti-cone block 232 fits the maximum diameter surface of the cone cap 2312, and the anti-cone block 232 is located in the claw seat 233 toward one end of each bevel portion 23331, so that when the column 2311 drives the cone cap 2312 to pull out the claw seat 233, the cone The cap 2312 pushes the minimum diameter surface of the anti-cone block 232 to abut against the right angle surface of each hook block 2333. Since the anti-cone block 232 is a conical structure, the anti-cone block 232 pushes each hook block 2333 to be spread outward with the axis of the bottom block 2331 as the center. Under the operation of each elastic member 234, each bevel portion 23331 will continue to abut against the anti-cone block 232, from the minimum diameter surface of the anti-cone block 232 to the right angle surface of the anti-cone block 232. The maximum diameter surface of the cone block 232 finally causes the reverse cone block 232 to break away from the abutment of the inclined surfaces. At the same time, as the cone cap 2312 is driven by the column 2311, it continues to push the reverse cone block 232. When the maximum diameter surface of the reverse cone block 232 slides over the beveled portions 23331, under the action of the elastic members 234, the beveled portions 23331 will gather toward the axis of the bottom block 2331. As the maximum diameter surface of the reverse cone block 232 is larger than the maximum diameter surface of the cone cap 2312, when the beveled portions 23331 gather toward the axis of the bottom block 2331, the beveled portions 23331 abut against the maximum diameter surface of the cone cap 2312 and gradually continue to slide toward the minimum diameter surface of the cone cap 2312. In this way, driven by the reverse cone block 232, the cone cap 2312 can pull out the claw seat 233, thereby allowing the cathode plate 50 to be quickly disassembled.

[0060] like Figure 3 、 Figure 14 As shown, in one embodiment, the latch assembly 23 further includes a bracket 235 and a guide cone 236. The bracket 235 is disposed on the bottom block 2331, and the guide cone 236 is disposed on the bracket 235. The guide cone 236 is used to guide the cone cap 2312 to be plugged into the hook block 2333. The minimum diameter of the guide cone 236 is greater than the maximum diameter of the counter cone block 232.

[0061] It should be noted that the bracket 235 is arranged on the circumferential surface of the bottom block 2331, and the bracket 235 faces the cathode sheet 50, the guide cone 236 is a conical ring structure, or the guide cone 236 is a funnel-shaped structure. The smallest diameter end of the guide cone 236 faces the claw seat 233, and the opening of the smallest diameter of the guide cone 236 is coaxial with the conical surface formed by each inclined angle part 23331, and the smallest diameter of the guide cone 236 is greater than the maximum diameter of the reverse cone block 232. Therefore, when installing or replacing the cathode sheet 50, the worker only needs to hold the end of the cathode sheet 50 away from the conical joint on the hanging bracket 211 and push the cathode sheet 50 downward. When the conical joint contacts the guide cone 236, the guide cone 236 guides the conical joint to abut against each inclined angle part 23331, so that the conical joint is inserted into the claw seat 233. When the conical joint is completely inserted into the claw seat 233, the worker inserts the other end of the cathode sheet 50 provided with the embedded block 221 into the hanging block 222. Therefore, the worker completes the replacement of the cathode sheet 50. Conversely, when the cathode sheet 50 needs to be disassembled, the embedded block 221 is slid out of the hanging block 222 by rotating the anti-disassembly block 223. The worker pushes the end of the cathode sheet 50 provided with the embedded block 221 toward the claw seat 233, so that the convex ring 23111 drives the reverse cone block 232 to slide into the claw seat 233. The worker pulls the cathode sheet 50 in the opposite direction, so that the reverse cone block 232 drives the conical joint 231 to pull out of the claw seat 233, so that the cathode sheet 50 is disconnected from the lower frame 212. Therefore, the worker can pull out the cathode sheet 50 from the anode tube 32 at the upper box body 11. Therefore, the worker can quickly disassemble and replace the cathode sheet 50, and avoid climbing back and forth between the upper box body 11 and the lower box body 13 when disassembling or replacing the cathode sheet 50, so as to reduce the work risk and improve the convenience of installation and replacement.

[0062] As shown in Figure 1 , Figures 4 to 5 illustrated, in an embodiment, a wet high-voltage electrostatic dust removal device 1 includes a box frame 10, a dust removal structure 30, and a cleaning structure 40. The box frame 10 is provided with an upper box body 11, a middle box body 12, and a lower box body 13. The middle box body 12 is located between the upper box body 11 and the lower box body 13, and both ends of the middle box body 12 are communicated with the upper box body 11 and the lower box body 13. A plurality of upper insulating columns 121 are arranged in the upper box body 11, and a plurality of lower insulating columns 131 are arranged in the lower box body 13. Each upper insulating column 121 is connected with an upper hanging bracket 211, and each lower insulating column 131 is connected with a lower frame 212.

[0063] It should be noted that there are multiple hanging assemblies 22, and each hanging assembly is evenly spaced on the upper hanger 211. It is important to note that each hanging assembly 22 is made of conductive material. One end of each cathode sheet 50 is connected to each hanging assembly 22, and the other end of each cathode sheet 50 is connected to each conical connector 231. Each claw seat 233 is provided on the lower frame 212. When the conical connector is inserted into the claw seat 233, the upper hanger 211 and the lower frame 212 are electrically connected. It is important to ensure that each hanging assembly 22, each cathode sheet 50, each conical connector, and each claw seat 233 corresponds to each other.

[0064] like Figure 1 、 Figure 4 As shown, in one embodiment, the dust removal structure 30 includes a high-voltage power supply 31 and a plurality of anode tubes 32. The high-voltage power supply 31 is arranged on the outer wall of the middle box body 12. The high-voltage power supply 31 is electrically connected to the anode tubes 32 and the upper hanger 211 / lower rack 212. Each anode tube 32 is arranged in the middle box body 12, and each anode tube 32 is connected to the upper box body 11 and the lower box body 13. The cathode plate 50 is located in the anode tube 32.

[0065] It should be noted that each cathode plate 50 is located within each anode tube 32, and each cathode plate 50 corresponds to each anode tube 32. When the upper hanger 211 and the lower hanger 212 are electrically connected to the high-voltage power supply 31, each cathode plate 50 discharges, generating a corona discharge that ionizes the surrounding gas, forming a large number of free electrons and positive ions. This process causes gas molecules and particulate matter in the exhaust gas to acquire an electric charge. These charged particles collide with the particulate matter in the exhaust gas, charging the particulate matter. The charged particulate matter then moves toward the anode tube 32 under the action of the electric field force and adheres to the inner wall of the anode tube 32, thereby removing dust particles from the gas.

[0066] like Figure 1 、 Figure 4 As shown, in one embodiment, the cleaning structure 40 includes a water tank 41, a nozzle 42 and a water pump 43. The water tank 41 and the water pump 43 are both arranged on one side of the lower box body 13, the nozzle 42 is arranged in the upper box body 11, the water outlet end of the water pump 43 is connected to the nozzle 42, and the water inlet end of the water pump 43 is connected to the water tank 41.

[0067] It should be noted that the nozzle 42 is arranged in the upper box body 11 and is located above the upper hanger 211, and the nozzle 42 is installed with multiple nozzles facing the upper hanger 211, and each nozzle is evenly distributed on the nozzle 42. In this way, when the water pump 43 pumps the water in the water tank 41 to the nozzle 42, the water is sprayed above each anode tube 32. Since each anode tube 32 is connected to the upper box body 11 and the lower box body 13, the water sprayed from the nozzle flushes the dust particles attached to the inner wall of the anode tube 32, causing the dust particles to fall into the lower box body 13 for discharge.

[0068] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
