Description

Technical Field

[0001] This utility model belongs to the field of electrostatic dust removal technology, and in particular relates to an electrostatic dust removal filter element with a flexible dust collection plate. Background Technology

[0002] Electrostatic precipitator (ESP) is a highly efficient gas purification technology widely used in industrial fume treatment, air purification, and dust prevention for electronic equipment. ESP uses a high-voltage electric field to charge dust particles and adsorb them onto the electrode surface. The dust collection plate, as the core component for discharge and dust collection, plays a crucial role in ESP. However, honeycomb micro-electrostatic precipitator filters are prone to clogging after dust accumulation due to their small pore size, making cleaning inconvenient and limiting their practicality. Patent CN218222908U discloses an electrostatic air filter comprising several parallel, equidistant, and staggered low-potential dust collection plates A and high-potential dust collection plates B. The front and rear ends of the low-potential dust collection plates A are connected by several vertical support bars A, and the front and rear ends of the high-potential dust collection plates B are also connected by several vertical support bars B. Both low-potential and high-potential dust collection plates A and B are equipped with charging slots. The low-potential dust collection plates A are used for electrostatic discharge. The high-potential dust collection plates B consist of an electrode diaphragm and an epoxy plate, with the electrode diaphragm embedded within the epoxy plate. Therefore, by separating the low-potential dust collection plate A and the high-potential dust collection plate B independently, problems such as current leakage are avoided, and dust particles and other debris are effectively isolated, thus improving the overall service life. However, since the dust collection plate is a flexible plate, it needs to be supported by support strips to prevent the densely arranged dust collection plates from deforming during the dust removal process, which could lead to damage or short circuits. This patent requires numerous support strips to fix the electrode plates, which not only increases wind resistance and reduces dust removal efficiency, but also reduces the dust collection area of ​​the dust collection plate and increases the dust accumulation rate of the support strips, making them difficult to clean and thus reducing the dust removal effect. Utility Model Content

[0003] This invention provides an electrostatic dust removal filter element with a flexible dust collection plate, which can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] An electrostatic dust collector filter element with a flexible dust collection plate includes a dust collection plate, a filter element frame, pressure strips, and a top cover.

[0036] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Therefore, they should not be construed as limitations on this utility model.

[0038] Reference Figure 1-16 As shown, an electrostatic dust collector filter element with a flexible dust collection plate includes a dust collection plate 1, a filter element frame 2, a pressure strip 3, and a top cover 4. Pull strips 11 are symmetrically distributed at intervals on both sides of the long side of the dust collection plate 1, and a conductive port 12 is provided at one end of the dust collection plate 1. The filter element frame 2 has slots 21 spaced apart on opposite sides, with both ends of the dust collection plate 1 located within the slots 21, and the conductive ports 12 of adjacent dust collection plates 1 are alternately distributed left and right. The pressure strip 3 is perpendicular to the dust collection plate 1, and a positioning hole 31 is provided on the pressure strip 3 corresponding to the pull strip 11, into which the pull strip 11 is inserted. The filter element frame 2 has a pressure opening 22 corresponding to the pressure strip 3, with both ends of the pressure strip 3 located within the pressure opening 22. The top cover 4 covers the filter element frame 2.

[0039] The positive and negative dust collection plates 1 are arranged alternately in the slots 21 of the filter frame 2, and are fixed in place by inserting the pull strip 11 into the positioning hole 31. The positive and negative conductive ports 12 are connected to conduct electricity by conductive adhesive.

[0040] Furthermore, the dust collection plate 1 is provided with a latch 16 at the corresponding pull strip 11.

[0041] The bayonet 16 serves to limit the length of the dust collection plate 1 on the one hand, and works together with the limiting plate 34 to limit the spacing between adjacent dust collection plates 1 on the other hand.

[0042] Due to the limiting effect of the pull strip 11, the setting depth of the buckle 16 is small, thus avoiding reducing the dust collection area of ​​the dust collection plate 1.

[0043] Furthermore, the pressure strip 3 is provided with a first positioning groove 32 on the opposite surface of the dust collection plate 1. The first positioning groove 32 is connected to each positioning hole 31. The pull strip 11 extends out of the positioning hole 31 into the first positioning groove 32. The first positioning groove 32 is provided with a first fixing adhesive or a first fixing strip 33.

[0044] The first fixing adhesive is injected into the first positioning groove 32 to fill the gap between the dust collection plate 1 and the first positioning groove 32, further improving the stability of the dust collection plate 1; or the first fixing strip 33 is used to bend the tie strip 11 and fix it in the first positioning groove 32, thereby achieving tensile fixation of the dust collection plate 1 in the width direction. Alternatively, the first fixing adhesive can be applied before using the first fixing strip 33.

[0045] Furthermore, the dust collection plate 1 has an electrode tab 13 at one end and a pull tab 14 at the other end. The filter frame 2 has a second positioning groove 23 on the outer side of the dust collection plate 1. The second positioning groove 23 is connected to the slot 21. The electrode tab 13 and the pull tab 14 extend into the second positioning groove 23. The second positioning groove 23 is provided with a second fixing adhesive or a second fixing strip 24. The electrode tabs 13 on the same side of the dust collection plate 1 are electrically connected to the conductive port 12 by using conductive adhesive or stacking end to end.

[0046] The tab 13, pull tab 14, second positioning groove 23, second fixing adhesive, and second fixing strip 24 achieve the stretching and fixing of the dust collection plate 1 along its length. The tab 13 serves as the conductive port 12.

[0047] Furthermore, the length of the tab 13 is greater than the spacing between adjacent dust collection plates 1 of the same polarity, and the length of the pull tab 14 is less than the spacing between adjacent dust collection plates 1 of the same polarity.

[0048] The length of the tab 13 is greater than the spacing between adjacent dust collection plates 1 of the same polarity, so as to realize the mutual stacking connection of the conductive ports 12 and improve the electrical connection performance.

[0049] Furthermore, the first positioning groove 32 and the second positioning groove 23 are dovetail-shaped, and the first fixing strip 33 and the second fixing strip 24 are corresponding fixing pins.

[0050] The dovetail-shaped positioning groove structure, combined with the fixing pin, allows the pull strip 11, electrode ear 13, or pull ear 14 to be bent while being pushed into the positioning pin from one end, resulting in a better fixing effect. Furthermore, the pushing process has a certain pulling effect on the pull strip 11, electrode ear 13, or pull ear 14, making the dust collection plate 1 more flat and preventing it from shaking or deforming during operation or rinsing.

[0051] Furthermore, a limiting plate 34 is provided between the positioning holes 31 respectively; the limiting plate 34 is square, or the limiting plate 34 has a "V" shaped cross section along at least one of the length or width directions of the dust collection plate 1.

[0052] The limiting plate 34 mainly serves a separating function and does not need to serve a positioning function; it can be set with a slight protrusion. The "V"-shaped limiting plate 34 facilitates the insertion of the pull strip 11 into the positioning hole 31.

[0053] Furthermore, the "V"-shaped limiting plate 34 is arc-shaped or triangular, the arc being a circular arc or a semi-ellipse, and the triangle being an equilateral triangle, a right triangle, or a scalene triangle.

[0054] The limiting plate 34 is used to connect the dust collection plate 1 and the pressure strip 3. The pressure strip 3 plays a supporting and fixing role and can be square or V-shaped to reduce dust accumulation and increase the dust collection area of ​​the dust collection plate 1.

[0055] sloping or curved surfaces can reduce wind resistance and dust accumulation, and are also easier to clean.

[0056] Furthermore, the dust collection plate 1 is provided with hooks 15 at both ends, and the filter frame 2 is provided with corresponding grooves 25.

[0057] The dust collection plate 1 can also be fixed and stretched along its length by using hooks 15 at both ends.

[0058] Furthermore, the hook 15 is located on the short side of the dust collection plate 1, the hook 15 is "L" shaped, and the width of the hook 15 at the conductive port 12 end is greater than the width at the other end.

[0059] The “L”-shaped hook 15 can be provided at both ends, located in the middle of the dust collection plate 1; or two symmetrical hooks 15 can be provided at each end, with the hooks 15 facing outwards, located at both ends of the width of the dust collection plate 1. In this case, the outer cover is also provided with grooves 25.

[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
