[0002] Bus ducts are widely used in various places, such as chemical, petroleum, medicine, electricity, etc. Bus ducts may be exposed to various chemicals, such as acids, alkalis, salts, etc. These chemicals are corrosive and may cause damage to the bus duct and its internal lines.

[0003] Since the working environment of bus duct is diverse and the risk of contact with chemical substances is high, the service life of bus duct can be effectively extended by improving its corrosion resistance to ensure system safety and reduce maintenance costs. Existing bus ducts usually use corrosion-resistant materials, such as fiberglass, stainless steel, etc., to improve the corrosion resistance of bus ducts. However, in actual use, due to the need for convenient installation, bus ducts mostly adopt a spliced ​​structure, and there is still a hidden danger of chemical substances entering the splicing. For this reason, the applicant has designed a corrosion-resistant and fire-resistant bus duct to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a corrosion-resistant and fire-resistant bus duct, comprising a bus duct body and two covers respectively arranged on both sides of the bus duct body,

[0006] The bus duct body is assembled by two half shells that are symmetrically distributed in the upper and lower parts. The left and right sides of the two ends of the two half shells are fixedly connected with blocks for fixing the cover shell. The cover shell cooperates with the block to form a hollow cavity on the outside of one side of the bus duct body, and the hollow cavity is filled with resin.

[0007] Preferably, mica gaskets distributed along the length direction of the half shells are glued to the inner side of the joint of the two half shells, and limiting ribs for positioning and installing the mica gaskets are provided on both inner side walls of the half shells.

[0028] 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.

[0029] See also Figure 1-6 The utility model provides a technical solution: a corrosion-resistant and fire-resistant bus duct, comprising a bus duct body 100 and two cover shells 200 respectively covering the two sides of the bus duct body 100, the bus duct body 100 is assembled by two half shells 110 symmetrically distributed in the upper and lower parts, and the left and right sides of the two ends of the two half shells 110 are fixedly connected with a blocking block 120 for fixing the cover shell 200, the cover shell 200 cooperates with the blocking block 120 to form a hollow cavity on the outside of one side of the bus duct body 100, and the hollow cavity is filled with resin 300.

[0030] Based on the above-mentioned structural setting, the corrosion-resistant and fire-resistant bus duct is composed of a bus duct body 100, two cover shells 200 and two groups of resins 300 respectively filled in the two cover shells 200, wherein the bus duct body 100 is composed of two half shells 110 assembled by means of a plurality of bolts, and the two cover shells 200 are respectively covered on the outside of the joints of the two sides of the bus duct body 100, and the blocking block 120, on the one hand, provides structural support for the assembly of the cover shell 200, and on the other hand, can cooperate with the outside of the cover shell 200 and the side of the bus duct body 100 to form a hollow cavity for filling with resin 300. Specifically, during the installation process, the operator first uses a plurality of bolts to symmetrically assemble the two half shells 110 above and below on the outside of the line, and then the operator sequentially covers the two cover shells 200 on the two sides of the bus duct body 100, and the cover shell 200 is screwed with the blocking block 120. 0 and the half shell 110 are fixedly connected. Finally, the operator pours and fills the resin 300 in the hollow cavities in the two cover shells 200 in turn. The resin 300 can be made of epoxy resin with good corrosion resistance. The corrosion-resistant and fire-resistant bus duct is provided with two cover shells 200 on both sides of the bus duct main body 100 which is formed by two half shells 110 symmetrically distributed up and down. With the cooperation of the blocking block 120, the two hollow cavities formed by the two cover shells 200 and the outside of the two sides of the bus duct main body 100 are filled with resin 300. On the one hand, the resin 300 can provide effective sealing for the gap at the joint of the two half shells 110 to prevent chemical substances from entering the interior of the bus duct main body 100 through the gap at the joint. On the other hand, the resin 300 cooperates with the hollow cavity to form a dense heat-insulating layer, which can effectively prevent high-temperature gas or open flame from directly entering the interior of the bus duct main body 100.

[0031] Furthermore, the mica gaskets 130 distributed along the length direction of the half shells 110 are glued to the inner side of the joint of the two half shells 110, and the two inner side walls of the half shells 110 are provided with limit retaining edges 1110 for positioning and installing the mica gaskets 130. Among them, the two mica gaskets 130 are glued to the inner side of the joint of the two half shells 110 along the length direction of the half shells 110, respectively. With the help of the mica gaskets 130, the sealing performance of the joint can be further ensured. At the same time, the mica gaskets 130 have excellent high temperature insulation performance, which can further improve the fire resistance of the bus duct body 100.

[0032] Furthermore, two heat dissipation fin seats 140 are respectively mounted on the top and bottom of the bus duct body 100, and thermal conductive silicone 150 is coated between the two heat dissipation fin seats 140 and the bus duct body 100. The heat dissipation fin seats 140 are composed of a substrate and a plurality of fins distributed in an array and vertically welded to the top of the substrate. The heat conductive silicone 150 coated between the heat dissipation fin seats 140 and the outer wall of the bus duct body 100 can form an effective heat dissipation path to improve the heat dissipation effect of the bus duct body 100.

[0033] Furthermore, two convex strips 1120 for positioning and installing the housing 200 are provided on the outer walls of the two half-shells 110, and the heat dissipation fin holder 140 is fixedly installed on the two convex strips 1120. Among them, the two convex strips 1120 are parallel to each other and are both provided on the outer walls of the half-shells 110. On the one hand, the convex strips 1120 can provide a limit for the side of the housing 200 to facilitate the positioning and installation of the housing 200. At the same time, the two convex strips 1120 provide structural support for the installation of the heat dissipation fin holder 140. The thermal conductive silicone 150 can be coated on the outer wall of the half-shell 110 between the two convex strips 1120.

[0034] Furthermore, a rubber ring 1210 is mounted on the outer wall of the block 120, and rubber strips 210 distributed along the length direction are glued to the inner walls of both sides of the cover 200. The rubber ring 1210 disposed on the outer wall of the block 120 and the rubber strips 210 disposed on the inner walls of both sides of the cover 200 are used to ensure the sealing performance of the hollow cavity to prevent the resin 300 from leaking out during the filling and pouring process of the resin 300.

[0035] Furthermore, the top of the housing 200 is provided with a plurality of pouring ports 220 evenly distributed at equal distances, and a partition 230 is welded between any two pouring ports 220 and on the inner wall of the housing 200. The resin 300 is filled into the hollow cavity through the pouring ports 220. Preferably, the hollow cavity can be divided into a plurality of unit cavities by means of a plurality of partitions 230, and each unit cavity is provided with a pouring port 220. By pouring separately, compared with a traditional single hollow cavity, it is helpful to optimize the pouring effect and ensure the density of the resin 300 filling.
