Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purifiers, in particular to an insulator for purification equipment. Background Art

[0002] Insulators are mainly used to support and isolate charged conductors to prevent current from flowing to unwanted places. In high-voltage electrostatic fume purifiers, multiple positive and negative plates are arranged at intervals in the fume channel to generate a high-voltage electric field, so that fume particles are charged and captured, thereby removing oil stains in the flue gas. Therefore, insulators are also needed to isolate and support the positive and negative plates in the field of high-voltage electrostatic fume purifiers.

[0003] Existing insulators for purification equipment usually include a high potential connection end and a low potential connection end, as well as two umbrellas located between the high potential connection end and the low potential connection end, and the umbrellas are connected by an annular groove with a rectangular or V-shaped cross section. Since the insulators for purification equipment are in an oil fume environment, the oil fume adheres to the surface of the insulator, especially to the annular groove with a rectangular or V-shaped cross section, which easily causes creepage and short circuits. Therefore, the insulators need to be cleaned regularly, and the existing insulators have steep angles between the umbrellas, so they are not easy to clean, which poses a safety hazard. In addition, the high potential connection end and the low potential connection end of the existing insulators for purification equipment are both flat planes. Therefore, arcing is very likely to occur at the high potential connection end and the low potential connection end, causing damage to the purification equipment components.

[0004] Therefore, an insulator for purification equipment that is easy to clean, can reduce the deposition of oil in the grooves between the umbrella bodies, and reduce the occurrence of creepage phenomena needs to be designed. Utility Model Content

[0005] The purpose of the utility model is to provide an insulator for purification equipment in view of the defects and shortcomings of the prior art, which at least solves one of the above-mentioned technical problems and has the advantages of being easy to clean, reducing the deposition of oil and dirt in the grooves between the umbrella bodies, and reducing the occurrence of creepage.

[0006] To achieve the above object, the utility model provides an insulator for purification equipment, comprising:

[0007] The insulating body has a high potential connection end and a low potential connection end relative to each other, and at least two umbrella bodies which are sequentially connected and located between the high potential connection end and the low potential connection end; an annular groove is used as a transition between two adjacent umbrella bodies, and the cross-section of the annular groove is arc-shaped.

[0008] Optionally, the high potential connection end has a first spherical crown-shaped groove arranged concentrically with the umbrella body, and the positive electrode plate is fixed in the first spherical crown-shaped groove by a first screw member.

[0009] Optionally, a first threaded hole is provided at the center of the first spherical crown groove, and the first threaded member and the first threaded hole are threadedly connected to fix the positive plate to the high potential connection terminal.

[0010] Optionally, a rounded transition is provided between the outer edge of the first spherical crown groove and the umbrella body.

[0011] Optionally, the low potential connection end has a second spherical crown-shaped groove arranged concentrically with the umbrella body, and the negative electrode plate is fixedly mounted in the second spherical crown-shaped groove by a second screw member.

[0012] Optionally, a second threaded hole is provided at the center of the second spherical crown groove, and the second threaded member and the second threaded hole are threadedly connected to fix the negative electrode plate to the high potential connection terminal.

[0013] Optionally, a rounded transition is provided between the outer edge of the second spherical crown groove and the umbrella body.

[0014] Optionally, the parachute body is in the shape of a flying saucer.

[0015] Optionally, the insulating body is made of Teflon in one piece.

[0016] Optionally, radial dimensions of at least two of the parachute bodies are the same.

[0017] Compared with the prior art, the advantages of this application are:

[0018] Since the two adjacent umbrella bodies of the insulator for the purification equipment are connected by an annular groove, and the cross section of the annular groove is arc-shaped, the oil and gas attached to the annular groove can flow along the surface of the umbrella body under the action of gravity, so that there is not much oil on the surface, so it is not easy to cause creepage. When cleaning it, it is easy to clean because there is no steep angle.

[0019] In addition, since the high potential connection end of the insulator for the purification equipment has a first spherical crown groove and the low potential connection end has a second spherical crown groove, the magnetic field between the high potential connection end and the low potential connection end is blocked by the first spherical crown groove and the second spherical crown groove, thereby reducing the occurrence of arcing.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] It should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "back", "side", "circumferential" and the like in the present invention indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present invention. In addition, the words "first", "second" and the like are only used to distinguish multiple components or structures with the same or similar structures, and do not represent any special limitation on the setting order or connection relationship.

[0038] Please refer to Figures 1 to 5 The embodiment of the utility model provides an insulator 100 for purification equipment, which is used to support and isolate the positive plate 6 and the negative plate 7 in a high-voltage electrostatic fume purifier (not shown in the figure). The insulator 100 for purification equipment includes: an insulating body. The insulating body has a high potential connection terminal 1, a low potential connection terminal 2 and at least two umbrella bodies 3. The high potential connection terminal 1 and the low potential connection terminal 2 are arranged relatively at the ends of the insulating body. At least two umbrella bodies 3 are connected in sequence and are located between the high potential connection terminal 1 and the low potential connection terminal 2, and the umbrella bodies 3 are connected in sequence. Specifically, an annular groove e is used to transition between two adjacent umbrella bodies 3, and the cross-section of the annular groove e is arc-shaped. Specifically, the insulating body is made of an insulating material, and the insulating material can be made of any one of polyester fiber or ceramic. In this embodiment, the insulating body can be made of Teflon integrally molded. Since the Teflon material can be directly tapped with a threaded hole by a self-tapping screw to achieve a threaded connection with the insulating body, there is no need to pre-embed metal internal threaded connectors (not shown in the figure) at the high potential connection end 1 and the low potential connection end 2 of the purification equipment insulator 100. In this way, when manufacturing the purification equipment insulator 100, high-temperature burning and cracking can be effectively prevented to improve safety.

[0039] Since the two adjacent umbrella bodies 3 of the insulator 100 for purification equipment are transitionally connected by the annular groove e, and the cross section of the annular groove e is arc-shaped, the oil and gas attached to the annular groove e can flow along the surface of the umbrella body 3 under the action of gravity during use, so that the surface does not have much oil and dirt, so it is not easy to cause creepage. When cleaning it, it is easy to clean because there is no steep angle.

[0040] In order to avoid arcing between the high potential connection terminal 1 and the low potential connection terminal 2 during operation, please refer to Figure 1 , Figure 3 and Figure 5In this embodiment, the high potential connection terminal 1 has a first spherical crown groove a concentrically arranged with the umbrella body 3, and the positive electrode plate 6 is fixedly fitted in the first spherical crown groove a by a first threaded member 4. Specifically, the first spherical crown groove a has a first threaded hole b at its center, and the first threaded member 4 is threadedly connected to the first threaded hole b to fix the positive electrode plate 6 to the high potential connection terminal 1. Optionally, a rounded transition is made between the outer edge 9 of the first spherical crown groove a and the umbrella body 3. It can be understood that the low potential connection terminal 2 also has the same structure, that is, the low potential connection terminal 2 has a second spherical crown groove c concentrically arranged with the umbrella body 3, and the negative electrode plate 7 is fixedly fitted in the second spherical crown groove c by a second threaded member 5. The second spherical crown groove c has a second threaded hole d at its center, and the second threaded member 5 is threadedly connected to the second threaded hole d to fix the negative electrode plate 7 to the high potential connection terminal 1. A rounded transition is made between the outer edge 10 of the second spherical crown groove c and the umbrella body 3. In this way, under the blocking of the first spherical crown groove a and the second spherical crown groove c, the magnetic field between the high potential connection terminal 1 and the low potential connection terminal 2 is blocked, thereby reducing the occurrence of arcing.

[0041] Optionally, see Figure 3 In this embodiment, the umbrella body 3 is in the shape of a flying saucer. That is, the umbrella body 3 is roughly formed by the lower bottom surfaces of two truncated cones buckled together. Optionally, in this embodiment, the radial dimensions of the two umbrella bodies 3 are the same. That is, the dimensions of the two umbrella bodies 3 are the same. Of course, in other embodiments, the radial dimensions of the two umbrella bodies 3 may also be different. And the number of umbrella bodies 3 is not limited to two, and three, four or more can be set according to actual needs to increase the creepage distance.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
