[0002] The dust collector concave-convex sleeve is used in electrostatic dust removal equipment and is used in conjunction with the anode plate. It is a type of electrostatic dust collector accessory and one of the essential dust removal accessories for electrostatic dust collectors.
[0003] The concave-convex sleeve is a conventional accessory of the electrostatic precipitator, and is used in large quantities in daily life. For a long time, it has been made by fine processing of round steel or by casting through molds, which has the problems of being too heavy and having too high production costs. Utility Model Content
[0004] (I) Purpose of the utility model
[0005] In order to solve the technical problems existing in the background technology, the utility model proposes a novel concave-convex sleeve, which has the characteristics of simple structure, reduced overall weight and production cost.
[0006] (II) Technical solution
[0007] In order to solve the above technical problems, the utility model provides a new type of concave-convex sleeve, including a concave sleeve and a convex sleeve that are arranged in a matched manner, the two are located at the same axis, and a through channel is left in the combined structure;
[0008] The concave sleeve is provided with an inwardly concave sleeve ring plate, the convex sleeve is provided with an outwardly convex sleeve ring plate on the end surface facing the concave sleeve, and a through ring seat is formed at one end of the convex sleeve penetrating into the inner cavity of the concave sleeve;
[0009] A cover plate is arranged on the other side of the convex sleeve, a convex edge ring is formed at the edge of the cover plate and sleeved on the outer wall of the convex sleeve, and a through hole is opened at the axis.
[0010] Preferably, a cavity is left inside the female sleeve and the male sleeve.
[0011] Preferably, the concave ring plate and the convex ring plate have the same inclination amplitude, and the inclination angle is at least 30°.
[0012] Preferably, the specification of the channel in the through-ring seat matches the specification of the through-hole of the cover plate.
[0013] Preferably, a concave-convex sealing member is clamped in the attachment gap between the concave sleeve ring plate and the through ring seat.
[0014] Preferably, a cover plate seal is clamped in the attachment gap between the convex edge ring and the convex sleeve.
[0015] The above technical solution of the utility model has the following beneficial technical effects:
[0016] 1. During assembly, the convex sleeve is placed into the inner cavity of the concave sleeve, the convex sleeve ring plate and the concave sleeve ring plate are attached, and the outer wall of the through-ring seat directly contacts the concave sleeve ring plate. Because the channel specification in the through-ring seat matches the through-hole specification of the cover plate, an installation channel for the pole line of the electrostatic precipitator is reserved at the axis to assist the installation of the pole line of the electrostatic precipitator. The cover plate reserves a through hole to ensure that the installation cavity of the pole line of the electrostatic precipitator is in a closed state to prevent a large amount of dust in the dusty environment in the electrostatic precipitator from acting on the installation cavity of the pole line of the electrostatic precipitator, and the dustproof performance is effectively improved. At the same time, the spare cavity can improve the heat dissipation effect.
[0017] 2. There are cavities inside the concave and convex sets. First, the blank size is punched out using scraps, then the blank is heated in an oven, and then it is stamped into shape, and then it is processed on a lathe to finally form it. The new concave and convex set is half the weight of the old one. At the same time, the new concave and convex set can be processed from steel plate scraps, which can greatly save costs.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0024] like Figure 1-3 As shown, the utility model proposes a novel concave-convex sleeve, comprising a matching concave sleeve 1 and a convex sleeve 3, both of which are located at the same axis, and a through passage is left in the combined structure;
[0025] The female sleeve 1 is provided with an inwardly concave female sleeve ring plate 2, and the end surface of the male sleeve 3 facing the female sleeve 1 is provided with an outwardly convex female sleeve ring plate 4, and one end of the male sleeve 3 penetrating into the inner cavity of the female sleeve 1 is formed with a through ring seat 5;
[0026] A cover plate 6 is disposed on the other side of the convex sleeve 3. A convex edge ring 7 is formed at the edge of the cover plate 6 and is sleeved on the outer wall of the convex sleeve 3. A through hole is opened at the axis.
[0027] Among them, the inclination amplitude of the concave ring plate 2 and the convex ring plate 4 is the same, and the inclination angle is 30°. The inclined ring plate surface increases the contact area between the two, and the connection points are increased during combination, thereby improving the combined load-bearing effect.
[0028] In this embodiment, when assembling, the convex sleeve 3 is inserted into the inner cavity of the concave sleeve 1, the convex sleeve ring plate 4 and the concave sleeve ring plate 2 are attached to each other, and the outer wall of the through-ring seat 5 directly contacts the concave sleeve ring plate 2. Because the channel specification in the through-ring seat 5 matches the through-hole specification of the cover plate 6, an installation channel for the electrostatic precipitator pole line is reserved at the axis center to assist the installation of the electrostatic precipitator pole line. The cover plate 6 reserves a through hole to ensure that the installation cavity of the electrostatic precipitator pole line is in a closed state, preventing a large amount of dust in the dusty environment in the electrostatic precipitator from acting on the installation cavity of the electrostatic precipitator pole line, and the dustproof performance is effectively improved.
[0029] It should be noted that: a cavity is reserved inside both the concave kit 1 and the convex kit 3. The cavity is a hollow structure except for the installation area of the electrostatic precipitator pole line, which is used for air heat exchange to facilitate heat dissipation.
[0030] As an example of the processing of concave and convex sleeves: first, use scraps to punch out the blank size, then heat the blank in an oven, then stamp it into shape, and then process it on a lathe to finally form it. The new concave and convex sleeve is half the weight of the old one. At the same time, the new concave and convex sleeve can be processed from steel plate scraps, which can greatly save costs.
[0031] In order to improve the dustproof performance of the inner cavity of the concave sleeve 1, further, a concave-convex sealing member 8 is clamped in the attachment gap between the concave sleeve ring plate 2 and the through-ring seat 5.
[0032] In order to improve the dust-proof performance of the combination of the cover plate 6 and the convex sleeve 3, further, the pole line of the electrostatic precipitator is passed through the through hole of the cover plate 6. At the same time, the convex edge ring 7 of the cover plate 6 is sleeved on the outer periphery of the convex sleeve 3, and the cover plate seal 9 is clamped in the attachment gap between it and the convex sleeve 3.
[0033] It should be added that: the concave-convex seal 8 and the cover seal 9 are both elastic structures, which can expand to fill the gap and seal the cavity to prevent dust.
[0034] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
