Description

Technical Field

[0001] The utility model belongs to the technical field of electrostatic precipitators, and particularly relates to an anode plate of a wear-resistant electrostatic precipitator. Background Art

[0002] In an electrostatic precipitator, the anode plate is one of the key components, primarily responsible for capturing charged dust. Anode plates are typically designed to be arranged side by side, but in practice, a certain gap is usually left between adjacent anode plates. Leaving gaps allows for more even distribution of airflow through the electrostatic precipitator, avoiding localized reductions in dust removal efficiency due to uneven airflow distribution. If there are no gaps between the anode plates, it can easily cause an electric field short circuit, impacting dust removal efficiency. The anode plates need to be regularly vibrated to remove dust adhering to their surfaces. If there are no gaps between the anode plates, the dust generated during vibration may be blocked by adjacent anode plates, impacting the cleaning effect.

[0003] Currently, when installing anode plates, due to the gaps between adjacent anode plates, multiple anode plates need to be fixed together with auxiliary reinforcement frames to increase the stability and strength of the installation. Therefore, when removing a single anode plate, it is necessary to remove the bolts or fixings at the connection between the auxiliary reinforcement frame and the anode plate to be removed, and then remove the fixing screws at both ends of the anode plate before the single anode plate can be removed.

[0004] The need to use an auxiliary reinforcement frame for fixation increases the complexity of installation. When disassembling a single anode plate, you must first remove the bolts or fasteners connected to the anode plate, and then remove the fixing screws at both ends of the anode plate. This process is cumbersome and time-consuming. Frequent disassembly and installation will cause wear on the auxiliary reinforcement frame and its connectors, increasing maintenance costs and replacement frequency. Disassembly and maintenance of anode plates in a limited space often requires a lot of manpower and time, which is especially evident in places where space is small or operation is inconvenient. The auxiliary reinforcement frame may hinder the free vibration of the anode plate to a certain extent, affecting the cleaning effect and resulting in incomplete removal of dust on the surface of the anode plate.

[0005] In view of this, we propose a wear-resistant electrostatic precipitator anode plate to solve the above problems. Utility Model Content

[0006] The present invention addresses the technical problem that the prior art requires the use of auxiliary reinforcement frames to secure the anode plates, which increases the complexity of installation. When disassembling a single anode plate, the bolts or fasteners connected to the anode plate must first be removed, followed by the screws securing the plates at both ends, a cumbersome and time-consuming process.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] An anode plate of a wear-resistant electrostatic precipitator, comprising an anode plate and fasteners. The fasteners are used to fasten two adjacent anode plates. Two adjacent anode plates are fastened by three groups of fasteners, and the three groups of fasteners are respectively arranged at the upper and lower ends and the central position of the anode plate;

[0009] Multiple grooves are pressed on the surface of the anode plate. The two sides of the anode plate are folded inward to form a U-shaped hem. The anode plate is made of stainless steel alloy, titanium alloy or nickel-based alloy material and is formed by casting, cold pressing and shearing, and stamping in sequence. A ceramic coating or high-temperature anti-corrosion paint is sprayed on the surface of the anode plate;

[0010] The fastener includes a left lock and a right lock. The left lock block on the left lock rotates and buckles into the right buckle groove of the right lock, and the right lock block on the right lock rotates and buckles into the left buckle groove of the left lock.

[0011] Preferably, the top end of the hem is bent into a J shape that bends inward and downward.

[0012] Preferably, the two sides of the anode plate are connected to the hem through inclined edges that slope downward and outward.

[0013] Preferably, mounting holes are symmetrically opened on both sides at the two ends of the anode plate. The design of the mounting holes enables the anode plate to be installed quickly and accurately in place.

[0014] Preferably, a lifting hole is opened along the center line direction at the top end of the anode plate. The lifting hole enables the anode plate to be conveniently transported and installed by a crane or other lifting equipment.

[0015] Preferably, the left buckle groove on the left lock is a semi-circular arc-shaped buckle groove, and the right buckle groove on the right lock is also a semi-circular arc-shaped buckle groove;

[0016] The left lock block includes a semi-circular arc-shaped left insertion block inserted into the left buckle groove on it and a semi-circular left limiting block limited in the semi-circular opening inside the left lock;

[0017] The right lock block includes a semi-circular arc-shaped right insertion block inserted into the right buckle groove on it and a semi-circular right limiting block limited in the semi-circular opening inside the right lock;

[0018] Preferably, the left lock also has a left arc-shaped guiding through hole connected to the left buckle groove on it. The semi-circular arc-shaped left insertion block is fixedly connected with a left拨动片 (left toggle piece) that penetrates through the left arc-shaped guiding through hole and moves along the left arc-shaped guiding through hole during the rotation of the semi-circular arc-shaped left insertion block;

[0019] When the left lock block rotates and buckles into the right buckle groove of the right lock, the left locking knob on the left toggle piece screws into the left positioning hole on the left lock, thereby locking and positioning the left lock block on the left lock and the right lock.

[0020] Preferably, the right lock buckle is further provided with a right arc-shaped guide through hole connected to the right buckle groove thereon, and the semicircular right insert block is fixedly connected to a right toggle piece that passes through the right arc-shaped guide through hole and moves along the right arc-shaped guide through hole when the semicircular right insert block rotates;

[0022] The design of the locking knob on the toggle piece being screwed into the positioning hole provides a quick locking method, so that the locking block can be quickly fixed, thereby improving installation efficiency.

[0023] Preferably, the mounting ears on the left lock buckle and the right lock buckle are respectively locked and fixed on the opposite folded edges of the two anode plates by bolts and nuts.

[0024] Compared with the prior art, the technical effects and advantages of the utility model are:

[0025] The anode plates of this wear-resistant electrostatic precipitator are tightly connected via specially designed semicircular buckle grooves and locking blocks. This design leverages the fit of the semicircular shape to allow the locking blocks to securely snap into the buckle grooves. The stoppers and toggle tabs ensure proper alignment and prevent displacement. This provides a tighter, more stable connection, reduces loosening due to vibration or impact, simplifies installation and removal, and improves operational safety and efficiency.

[0026] The modular structure of the anode plates, along with their grooved and folded edges, leverages airflow dynamics to optimize electric field distribution and enhance dust removal efficiency. The J-shaped structure and beveled edges of the folds promote dust shedding and smooth airflow, reducing eddy currents and dead zones, thereby maintaining electric field uniformity. Benefits include improved dust removal efficiency, reduced dust accumulation on the anode plates, and reduced secondary dust entrainment.

[0027] The symmetrical mounting holes at both ends of the anode plate and the top lifting hole, along with the quick-connect fastener design, embody the principle of modular design, which reduces maintenance costs and improves efficiency by simplifying component installation and replacement. The bolt and nut fastening and the rotating fastener design enable quick installation and replacement of the anode plate. This reduces maintenance time and labor intensity, while also improving the stability of the connection between the anode plate and the electrostatic precipitator frame, reducing vibration and displacement, and thus enhancing the overall stability and safety of the equipment.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The following is combined with Figure 1-6 To further explain this application,

[0037] The present application discloses an anode plate for a wear-resistant electrostatic precipitator, comprising an anode plate 1 and a fastener 7. The fastener is used to fasten two adjacent anode plates 1. The two adjacent anode plates 1 are fastened together by three sets of fasteners 7. The three sets of fasteners 7 are arranged at the upper and lower ends and the center of the anode plate 1 respectively.

[0038] On the surface of the anode plate 1, multiple grooves 2 are pressed. On both sides of the anode plate 1, flanges 3 are folded inward to form a U-shape, and the top end of the flange 3 is bent into a J-shape that bends inward and downward. The J-shaped design of the flange 3 helps the dust to fall off. Especially when the anode plate 1 is vibrated for dust cleaning, this shape can promote the dust to slide along the flange 3, reducing the accumulation of dust on the anode plate 1. The J-shaped design of the flange 3 helps to reduce the air flow interference caused by dust accumulation, has the effect of suppressing dust and preventing secondary dust flying, and maintains the uniformity of the electric field. Both sides of the anode plate 1 are connected to the flange 3 through inclined edges 4 that slope downward and outward. The design of the inclined edge 4 helps the air flow to pass smoothly, reduces the air flow turbulence caused by the shape of the anode plate 1, and improves the dust removal efficiency of the electrostatic precipitator. The inclined edge 4 can prevent the dust removed during the vibration process from being re-adsorbed onto the anode plate 1 and keeps the anode plate 1 clean.

[0039] The anode plate 1 is made of stainless steel alloy, titanium alloy or nickel-based alloy materials and is successively cast, cold-pressed and sheared, and stamped into shape. The surface of the anode plate 1 is sprayed with a ceramic coating or high-temperature anti-corrosion paint; it is made of high wear-resistant and corrosion-resistant materials and the surface is specially treated, improving the resistance of the anode plate 1 to the impact of dust particles, and at the same time enhancing its stability in high-temperature, high-humidity and corrosive gas environments. High-performance stainless steel alloy or other special alloy materials, such as titanium alloy, nickel-based alloy, etc., are used to ensure that the anode plate 1 has excellent corrosion resistance. Advanced coating technologies, such as ceramic coatings, high-temperature anti-corrosion paints, etc., are used on the surface of the anode plate 1 to enhance the wear resistance and anti-corrosion performance. It has strong anti-deformation ability under high temperature and vibration, and good vibration acceleration transmission performance.

[0040] At both ends of the anode plate 1, mounting holes 5 are symmetrically arranged on both sides. The design of the mounting holes 5 enables the anode plate 1 to be quickly and accurately installed in place, improving the installation efficiency and convenience. By fixing the anode plate 1 through the mounting holes 5, the connection stability between the anode plate 1 and the electrostatic precipitator frame can be enhanced, reducing vibration and displacement. Along the center line direction at the top of the anode plate 1, a lifting hole 6 is provided. The lifting hole 6 enables the anode plate 1 to be conveniently transported and installed by a crane or other lifting equipment, reducing the manual labor intensity. Using the lifting hole 6 can avoid the operator directly contacting the anode plate 1 during the installation process, reducing the safety risk.

[0041] The fastener 7 includes a left lock 8 and a right lock 9. The left lock block 81 on the left lock 8 is rotatably buckled in the right buckle groove 92 of the right lock 9, and the right lock block 91 on the right lock 9 is rotatably buckled in the left buckle groove 82 of the left lock 8. The mounting ears 10 on the left lock 8 and the right lock 9 are respectively locked and fixed on the flanges 3 of the two butt-jointed anode plates 1 through bolts and nuts. Fixing the lock through bolts and nuts on the flange 3 of the anode plate 1 provides additional fixing force to ensure a more firm connection between the anode plates 1.

[0042] The left buckle groove 82 on the left lock buckle 8 is a semicircular buckle groove, and the right buckle groove 92 on the right lock buckle 9 is also a semicircular buckle groove; the left lock block 81 includes a semicircular left insert block inserted into the left buckle groove 82 and a semicircular left limit block 84 limited in the semicircular opening inside the left lock buckle 8; the right lock block 91 includes a semicircular right insert block 93 inserted into the right buckle groove 92 and a semicircular right limit block 94 limited in the semicircular opening inside the right lock buckle 9;

[0043] The left lock buckle 8 is further provided with a left arc-shaped guide hole 85 connected to the left buckle groove 82 thereon. The semicircular left insert block 83 is fixedly connected to a left paddle 86 that passes through the left arc-shaped guide hole 85 and moves along the left arc-shaped guide hole 85 when the semicircular left insert block 83 rotates.

[0044] When the left locking block 81 is rotated and buckled into the right buckle groove 92 of the right lock buckle 9, the left locking knob 87 on the left toggle piece 86 is screwed into the left positioning hole 88 on the left lock buckle 8 to lock and position the left locking block 81 on the left lock buckle 8 and the right lock buckle 9.

[0045] The right lock buckle 9 is further provided with a right arc-shaped guide hole 95 connected to the right buckle groove 92 thereon, and the semicircular right insert block 93 is fixedly connected with a right paddle 96 which passes through the right arc-shaped guide hole 95 and moves along the right arc-shaped guide hole 95 when the semicircular right insert block 93 rotates;

[0046] When the right locking block 91 is rotated and buckled into the left buckle groove 82 of the left lock buckle 8, the right locking knob 97 on the right toggle piece 96 is screwed into the right positioning hole 98 on the right lock buckle 9 to lock and position the right locking block 91 on the left lock buckle 8 and the right lock buckle 9.

[0047] The semicircular buckle slot and locking block design provide a tighter connection, reducing loosening caused by vibration or impact. The semicircular design allows the locking block to snap into the buckle slot more easily, and the adaptability of the shape also makes removal easier. The semicircular stop block ensures the locking block is in the correct position, preventing it from shifting during operation, while the design of the toggle plate and locking knob provides a simple and effective locking mechanism. As the locking knob is screwed into the positioning hole, the operator can clearly feel that the locking block is firmly locked, which increases the safety of operation.

[0048] The curved guide hole and toggle design guide the locking block to precise alignment, simplifying the installation process and reducing the possibility of incorrect connection. The locking knob on the toggle screws into the positioning hole, providing a quick locking method, allowing the locking block to be quickly secured and improving installation efficiency.

[0049] The anode plate of this wear-resistant electrostatic precipitator is designed as a modular structure. Two adjacent anode plates 1 are buckled through fasteners 7, which is convenient for quick replacement and cleaning, reducing the maintenance cost. The design of the left lock 8 and the right lock 9 allows for quick connection and disassembly between the anode plates 1 through rotational fastening. This design reduces the complexity and time required for the traditional bolt connection method. Through the modular design, the anode plate 1 can be quickly replaced independently instead of requiring overall disassembly, which not only reduces the maintenance time but also the maintenance difficulty. The groove 2 design and the hem 3 structure on the anode plate 1 help to guide the air flow, reduce eddy currents and dead zones, thereby optimizing the electric field distribution and the dust removal efficiency. It is easy to clean the ash and suck the dust, enabling the dust collection area to increase by about 10%. The U-shaped hems 3 on both sides of the anode plate 1 not only increase the rigidity of the anode plate 1 but also form a windproof groove, which can prevent the secondary flying of the dust shaken off by the rapping.

[0050] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
