Description

Technical Field

[0001] The invention relates to the technical field of electrostatic dust collectors, and in particular to a seat and a dust collector. Background Art

[0002] Compared with traditional physical filtration dust removal technology, electrostatic dust collection technology has the advantages of zero consumables and lower maintenance costs. Electrostatic dust removal household products are becoming more and more popular and have broad application prospects.

[0003] Electrostatic dust removal technology is an important method for gas dust removal, such as Figure 1 As shown, Figure 1 The figure is a schematic diagram of the principle of electrostatic dust collection; its basic working principle is: the gas containing particle dust first passes through the corona electrode wire 3', and then is electrically separated when passing through the dust collecting electric field formed by the discharge electrode piece 2' and the collecting electrode piece 1', so that the particle dust is charged and tends to the collecting electrode piece 1' with the opposite charge, that is, under the action of the electric field force, the charged particle dust is "pushed" to the surface of the collecting electrode piece 1', thereby achieving the effect of electrostatic dust removal.

[0004] See also Figure 2 and Figure 3 As shown, Figure 2 It is a structural schematic diagram of an electrostatic precipitator in the prior art. Figure 3 for Figure 2 The partial enlarged view of part A in the figure; the electrostatic precipitator includes a discharge electrode and a collection electrode, both of which are made of conductive plastic. Figure 3 It can be seen from the figure that since there is no insulation between the discharge electrode and the collector electrode, leakage tracking is easily generated between the discharge electrode and the collector electrode, thus forming a conductive path. Figure 1 The effective distance d of the electric field becomes very small, making it easy for arc discharge to occur.

[0005] The arc discharge of the electrode is a common problem encountered by electrostatic dust removal products. Arc discharge will produce bright arc light columns, causing electrode spots, causing leakage tracking, and gradually forming a conductive path between the discharge electrode and the collection electrode, weakening the electric field strength between the electrodes, thereby affecting the dust collection efficiency. In addition, the electric sparks generated by arc discharge are also a safety hazard. Therefore, how to solve this technical problem is extremely important.

[0006] Therefore, the present application provides a new seat and dust collector to solve the above problems. Summary of the invention

[0054] Embodiment 1

[0055] See also Figure 4-Figure 10 As shown, this embodiment provides a seat body, including a base 1 and a partition 2 arranged on the base;

[0056] The partition 2 is made of insulating material;

[0057] See also Figure 4 As shown, there are multiple partitions 2, and the multiple partitions 2 are arranged at intervals along the length direction of the base;

[0058] A slot 21 for inserting a pole piece is formed between adjacent partitions 2 .

[0059] Preferably, the plurality of partitions 2 are parallel to each other, and the partitions 2 are perpendicular to the length direction of the base 1 .

[0060] It should be noted that the electrode pieces include a collecting electrode piece 81 and a discharging electrode piece 82 .

[0061] When in use, the discharge electrode sheet and the collecting electrode sheet are respectively inserted into the slots, so that the discharge electrode sheet and the collecting electrode sheet are arranged in sequence along the length direction of the base, that is, the discharge electrode sheet and the collecting electrode sheet are alternated. For example, the discharge electrode sheet, the collecting electrode sheet, the discharge electrode sheet, the collecting electrode sheet, etc. are arranged in sequence from the slot at one end to the slot at the other end along the length direction of the base, or the collecting electrode sheet, the discharge electrode sheet, the collecting electrode sheet, the discharge electrode sheet, etc.

[0062] In summary, the seat provided in this embodiment allows the collecting electrode and the repelling electrode to be isolated in their respective slots by insulating partitions, thereby increasing the creepage distance of the collecting electrode and the repelling electrode, and preventing the electrode from being damaged by arcs by increasing the arc discharge path, thereby preventing the electrode from being damaged by arcs, thereby solving the technical problem of arc discharge in existing electrostatic dust removal products.

[0063] Preferably, see Figure 6 As shown, the same ends of the adjacent partitions 2 along the length direction are connected by a connecting plate 3.

[0064] When inserting the discharge electrode sheet and the collection electrode sheet into the slot, the discharge electrode sheet and the collection electrode sheet are inserted into the slot from one end of the slot away from the connection sheet along the length direction.

[0065] Optionally, the partition plate 2 and the connecting plate 3 are integrally formed or connected by bonding, screwing or the like.

[0066] Not only does it realize the limiting function of inserting the discharge electrode sheet and the collection electrode sheet in the slot, but also the closed structure of the slot further blocks the arc discharge path.

[0067] Preferably, the connecting plate 3 is an arc-shaped plate, and the arc-shaped concave surface is away from the partition plate, so that the slot 21 forms a U-shaped slot.

[0068] Preferably, see Figure 6 As shown, a socket is formed at one end of the adjacent partition plate 2 away from the connecting plate 3 along the length direction;

[0069] Along the length direction of the base 1 , adjacent sockets are respectively located at two ends of the partition 2 along the length direction.

[0070] When in use, insert the pole piece from the socket into the slot.

[0071] In summary, the adjacent pole pieces are plugged in, see Figure 6 As shown, the collecting electrode is inserted into the slot from the socket in the direction of a and extends along the length direction of the slot to the side close to the connecting plate, and the discharging electrode is inserted into the slot from the socket in the direction of b and extends along the length direction of the slot to the side close to the connecting plate, or the collecting electrode is inserted into the slot from the socket in the direction of b and extends along the length direction of the slot, and the discharging electrode is inserted into the slot from the socket in the direction of a and extends along the length direction of the slot.

[0072] Preferably, see Figure 7 As shown, a positioning column 4 is provided on the partition, and the positioning column 4 is provided in the slot 21;

[0073] The length direction of the positioning column 4 is parallel to the height direction of the partition 2;

[0074] There are a plurality of positioning posts 4 , and the plurality of positioning posts 4 are arranged at intervals along the length direction of the partition 2 .

[0075] Preferably, positioning columns are provided on both sides of the partition along the thickness direction, so that both sides of the pole piece and the partition are positioned and fixed by the positioning columns.

[0076] It should be noted that the length direction of the partition is consistent with the length direction of the slot, the height direction of the partition is consistent with the depth direction of the slot, and the length direction of the slot is perpendicular to the depth direction of the slot.

[0077] During use, the pole piece contacts the positioning post, achieving the positioning and fixation of the pole piece. That is, the pole piece is inserted into the slot through the positioning post, forming a line contact with the slot instead of a surface contact, greatly reducing the probability of the pole piece creeping along the separator to form a creepage path.

[0078] Preferably, as shown in Fig. 9 the seat body described in this embodiment further includes a conductive bar 5 connected to the base 1;

[0079] The conductive bar 5 is made of a conductive material;

[0080] The length direction of the conductive bar 5 is parallel to the length direction of the base 1, and the conductive bar 5 is arranged at one end of the separator 2 along the length direction, so that when the discharge electrode piece is inserted into the slot, the discharge electrode piece is in electrical contact with the conductive bar.

[0081] Optionally, the conductive bar and the base are connected by bolts or by clamping or buckling.

[0082] After the discharge electrode piece is inserted into the slot, multiple discharge electrode pieces are all electrically connected to the conductive bar. When the conductive bar is energized, multiple discharge electrode pieces are energized, and an equipotential potential is formed, ensuring that the electric field intensities participated by multiple discharge electrode pieces are the same.

[0083] Preferably, an elastic clip 6 is provided on the conductive bar;

[0084] There are multiple elastic clips 6, and the multiple elastic clips 6 are arranged at intervals along the length direction of the conductive bar 5;

[0085] The elastic clip 6 is arranged on the side of the slot where the discharge electrode piece is located, close to the connecting plate, so that when the discharge electrode piece is inserted into the slot, the discharge electrode piece is clamped in the elastic clip.

[0086] Preferably, the elastic clip 6 includes a first elastic clip tongue 61 and a second elastic clip tongue 62, and the first elastic clip tongue 61 and the second elastic clip tongue 62 are arranged opposite to each other. The minimum distance between the first elastic clip tongue 61 and the second elastic clip tongue 62 is d;

[0087] As shown in Fig.10 the thickness of the discharge electrode piece is c, and d < c. When the discharge electrode piece is inserted into the slot, the first elastic clip tongue and the second elastic clip tongue of the elastic clip are撑开, and the elastic action makes the first elastic clip tongue and the second elastic clip tongue firmly hold the discharge electrode piece. Therefore, the problem of the risk of low dust collection efficiency caused by poor contact between the discharge electrode piece and the conductive bar can be effectively solved, ensuring that each discharge electrode piece can be conducted.

[0088] Preferably, as shown in Figure 5 the seat body described in this embodiment further includes a bottom plate 7;

[0089] The bottom plate 7 is arranged on one side of the slot close to the base in the depth direction, blocking the arc discharge and tip discharge paths of the discharge electrode sheet and the collection electrode sheet.

[0090] Preferably, the partition 2 has a height, and the height of the partition is greater than the height of the pole piece, that is, the pole piece is inserted into the slot, and along the length direction of the base, the pole piece is projected into the partition, so that the partition forms a wall for the pole piece, blocking the arc discharge and tip discharge paths of adjacent collecting pole pieces and discharge pole pieces.

[0091] Preferably, along the length direction of the base, one of the adjacent slots is a first slot and the other is a second slot. Figure 8a As shown, a first opening 91 is provided on the base, the first opening 7 is connected to the first slot, and the first opening is provided at the bottom of the first slot; see Figure 8b As shown, a second opening 92 is provided on the base, the second opening 92 is communicated with the second slot, and the second opening is provided at the bottom of the second slot, and the first opening and the second opening are respectively located at two ends of the partition along the length direction.

[0092] That is, along the length direction of the base, the first opening 91 and the second opening 92 are spaced apart.

[0093] When the dust collector is being cleaned, the water in the slot flows out from the openings on both sides. Specifically, the water in the first slot flows out from the first opening, and the water in the second slot flows out from the second opening. The two openings formed flow out from two opposite butting openings, and the two openings are inclined downward. This makes it difficult for water to accumulate in the slot, greatly shortens the drying time of the seat, and reduces the discharge phenomenon caused by the conduction of water.

[0094] Preferably, each collecting electrode is integrated on the collecting electrode plate and adopts a non-crystalline, hydrophobic, V0 flame retardant grade, and a volume resistivity of less than 10 6 Ω.cm conductive plastic material is integrally injection molded.

[0095] Embodiment 2

[0096] Embodiment 2 provides a dust collector, the dust collector includes the base body described in embodiment 1, the technical features of the base body disclosed in embodiment 1 are also applicable to this embodiment, and the technical features of the base body disclosed in embodiment 1 are not described repeatedly. The implementation of the dust collector is further described in detail below in conjunction with the accompanying drawings.

[0097] To save space, the improved features of this embodiment are also reflected in Figure 4-Figure 10 Therefore, combined with Figure 4-Figure 10 The scheme of this embodiment will be described.

[0098] See also Figure 4-Figure 10 As shown, the dust collector provided in this embodiment includes the base body, and also includes a collecting electrode 81 and a discharging electrode 82;

[0099] The collecting electrode sheet 81 and the discharging electrode sheet 82 are inserted into the slot 21 in sequence and at intervals along the length direction of the base 1 .

[0100] The discharge electrode sheet and the collecting electrode sheet are arranged in sequence along the length direction of the base. For example, the discharge electrode sheet, the collecting electrode sheet, the discharge electrode sheet, the collecting electrode sheet, etc. are arranged in sequence from the slot at one end to the slot at the other end along the length direction of the base, or the collecting electrode sheet, the discharge electrode sheet, the collecting electrode sheet, the discharge electrode sheet, etc. are arranged in sequence.

[0101] To sum up, the dust collector provided in this embodiment isolates the collecting electrode and the repelling electrode in their respective slots, increases the creepage distance of the collecting electrode and the repelling electrode, and avoids arc damage to the electrode by increasing the arc discharge path, thereby avoiding arc damage to the electrode, further solving the technical problem of arc discharge in existing electrostatic dust removal products.

[0102] Preferably, the edge of the collecting electrode 81 has a smooth transition;

[0103] And / or, the edge of the discharge electrode sheet 82 has a smooth transition.

[0104] Specifically, the edge of the collecting electrode piece has a smooth transition; or, the edge of the discharging electrode piece has a smooth transition; or, the edge of the collecting electrode piece has a smooth transition, and the edge of the discharging electrode piece has a smooth transition.

[0105] Preferably, the edge of the collecting electrode sheet is smoothly transitioned, and the edge of the discharging electrode sheet is smoothly transitioned.

[0106] In the prior art, see Figure 1 As shown in the figure, each discharge electrode has a tip. The tip of the electrode here has a relatively large curvature and a high surface charge density. The electric field strength near it is particularly strong, so that it is easy to break down and ionize the air to form positive and negative ions. The ions in the air with the opposite charge to the electrode will neutralize the charge of the electrode, weaken the electric field strength between the electrodes, and discharge sparks will appear. A "sizzling" discharge sound can be heard, which means that tip discharge has occurred. Tip discharge will also affect the dust collection efficiency of the overall dust collection module.

[0107] On the one hand, since each electrode piece of the dust collector provided by this embodiment is in its own slot, even if a relatively strong electric field is generated at the tip of the electrode piece, tip discharge will not occur. On the other hand, the edge of the collecting electrode piece has a smooth transition, and the edge of the collecting electrode piece has a smooth transition, thereby effectively avoiding tip discharge.

[0108] Preferably, the discharge electrode sheet 82 is wrapped with an insulating sleeve.

[0109] Optionally, the insulating sleeve is a heat shrinkable insulating sleeve 405 or other insulating materials to further reduce the risk of tip discharge.

[0110] The dust collector described in this embodiment has the advantages of the seat described in the first embodiment, which have been described in detail in the first embodiment and will not be repeated here.
