Description

Technical Field

[0001] This utility model relates to the field of mica heater technology, specifically to a corrosion-resistant mica heater shell splicing structure. Background Technology

[0002] Mica heaters utilize the excellent insulation and high-temperature resistance of mica sheets, using mica plates as the skeleton and insulation layer, supplemented by galvanized plates or stainless steel plates for support and protection.

[0003] Traditional shell assembly methods often use simple bolt fixing, which is cumbersome to install and disassemble, requiring tools and is time-consuming and labor-intensive. It also hinders quick repair and replacement. Furthermore, traditional shell assembly structures have poor sealing, allowing corrosive gases or liquids to seep in through gaps, corroding the mica heating element and its electrical connections, thus affecting the heater's lifespan and safety. In addition, traditional assembly structures lack stability during fixing, easily loosening or detaching during use, resulting in an unstable connection between the heater shell and the pipeline, affecting the heater's normal operation.

[0004] Therefore, a corrosion-resistant mica heater shell splicing structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a corrosion-resistant mica heater shell splicing structure in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A corrosion-resistant mica heater housing splicing structure includes a heater housing with an anti-corrosion coating on its surface. A mica heating component is disposed on the surface of the heater housing. A first connecting plate and a second connecting plate are fixedly installed on the surface of the heater housing and at its two side edges, respectively. A through groove is formed on the surface of the first connecting plate, and a slot is formed on the surface of the second connecting plate. A connecting seat is rotatably installed in the through groove, and a spring-loaded quick-release assembly is threaded onto the connecting seat for quick installation and disassembly of the heater housing and the pipeline.

[0007] Furthermore, the mica heating assembly includes a mica heating element fixedly installed inside the heater housing, and a socket is fixedly installed on the surface of the heater housing. A connecting electrode is fixedly inserted into the heater housing and the socket, and the connecting electrode is electrically connected to the mica heating element.

[0008] Furthermore, two sets of corrosion-resistant silicone sealing rings are fixedly installed on the inner wall of the heater housing, and the two sets of corrosion-resistant silicone sealing rings are located between the mica heating plate and the heater housing, for filling the gap between the mica heating plate and the heater housing.

[0009] Furthermore, the connecting seat includes a rotating shaft rotatably mounted on both sides of the through groove, and a mounting shaft is fixedly mounted on the surface of the rotating shaft at its center, and the surface of the end of the mounting shaft is provided with an external thread.

[0010] Furthermore, the spring-loaded quick-release assembly includes an internally threaded knob threaded onto an external thread. A ring is rotatably mounted at the end of the internally threaded knob. A pressure spring is fixedly mounted at the end of the ring, and a retaining ring is fixedly connected to the end of the pressure spring. The ring and the retaining ring are rotatably fitted with the mounting shaft, and two sets of handles are fixedly mounted on the end face of the retaining ring.

[0011] Furthermore, when the heater housing is fixed to the surface of the pipe, and the mounting shaft is located in the slot, the end of its retaining ring is tightly fitted to the surface of the second connecting plate. At this time, the pressure spring is compressed, and the pressure spring is used to tighten and fix the heater housing to the pipe.

[0012] The beneficial effects of this utility model are as follows: By setting up a connecting seat and a spring-loaded quick-release assembly, the elasticity of the spring-loaded quick-release assembly can be used to achieve quick installation and disassembly of the heater housing and the pipeline. Two sets of corrosion-resistant silicone sealing rings are fixedly installed on the inner wall of the heater housing, located between the mica heating element and the heater housing. They are used to fill the gaps between the mica heating element and the heater housing. The corrosion-resistant silicone sealing rings can effectively prevent corrosive gases or liquids from seeping into the gaps, protect the mica heating element and its electrical connection parts from corrosion, extend the service life of the heater, and at the same time prevent heat loss from the gaps, thus improving heating efficiency.

[0018] like Figures 1 to 5 As shown, a corrosion-resistant mica heater housing assembly structure includes a heater housing 1, the surface of which is coated with an anti-corrosion coating, and a mica heating element 2 is disposed on the surface of the heater housing 1; as shown Figure 2As shown, specifically, the mica heating assembly 2 includes a mica heating element 201 fixedly installed inside the heater housing 1, and an insertion port 202 is fixedly installed on the surface of the heater housing 1. A connecting electrode 203 is fixedly inserted into the heater housing 1 and the insertion port 202, and the connecting electrode 203 is electrically connected to the mica heating element 201.

[0019] More specifically, during operation, the power supply is connected to the socket 202, and the current is conducted through the connecting electrode 203 to the mica heating element 201, which generates heat, thereby realizing the heating function and ensuring the normal operation of the heater.

[0020] like Figure 1 and Figure 2 As shown, in some practical applications, two sets of corrosion-resistant silicone sealing rings 3 are fixedly installed on the inner wall of the heater housing 1, and the two sets of corrosion-resistant silicone sealing rings 3 are located between the mica heating plate 201 and the heater housing 1, and are used to fill the gap between the mica heating plate 201 and the heater housing 1.

[0021] More specifically, during the operation of the heater, the corrosion-resistant silicone sealing ring 3 can effectively prevent corrosive gases or liquids from seeping in through the gaps, protect the mica heating element 201 and its electrical connection parts from corrosion, extend the service life of the heater, and at the same time prevent heat loss from the gaps, thus improving heating efficiency.

[0022] A first connecting plate 4 and a second connecting plate 5 are fixedly installed on the surface of the heater housing 1 and at its two side edges, respectively. The surface of the first connecting plate 4 has a through groove 41, and the surface of the second connecting plate 5 has a retaining groove 51. A connecting seat 6 is rotatably installed within the through groove 41. Figure 3 and Figure 4 As shown, specifically, the connecting seat 6 includes a rotating shaft 601 rotatably mounted on both sides of the through groove 41, and a mounting shaft 602 is fixedly mounted on the surface of the rotating shaft 601 and located at its center. The surface of the end of the mounting shaft 602 is provided with an external thread 603.

[0023] More specifically, the rotating shaft 601 can rotate around the side wall of the through groove 41, thereby adjusting the position of the mounting shaft 602 so that the mounting shaft 602 is aligned with the slot 51 and inserted. The quick-release assembly 7 with spring clips on the surface of the mounting shaft 602 can achieve a firm and reliable connection to the heater housing 1.

[0024] The connector 6 is threaded with a spring-loaded quick-release assembly 7 for quick installation and removal of the heater housing 1 from the pipe; such as Figure 3 , Figure 4 and Figure 5As shown, specifically, the spring-loaded quick-release assembly 7 includes an internally threaded knob 701 threaded onto the external thread 603. A ring 702 is rotatably mounted on the end of the internally threaded knob 701. A pressure spring 703 is fixedly mounted on the end of the ring 702, and a retaining ring 704 is fixedly connected to the end of the pressure spring 703. The ring 702 and the retaining ring 704 are rotatably fitted with the mounting shaft 602. Two sets of handles 705 are fixedly mounted on the end face of the retaining ring 704.

[0025] More specifically, when it is necessary to fix the heater housing 1 to the pipe, before aligning the mounting shaft 602 with the slot 51 and inserting it, pull the handle 705 to move the retaining ring 704 axially along the mounting shaft 602, compressing the pressure spring 703. After the mounting shaft 602 is inserted into the slot 51, release the handle 705. Under the elastic force of the pressure spring 703, the retaining ring 704 applies pressure to the surface of the second connecting plate 5, making the retaining ring 704 tightly press against the surface of the second connecting plate 5, thereby clamping and fixing the heater housing 1. When disassembly is required, pull the handle 705 to separate the retaining ring 704 from the surface of the second connecting plate 5, thus compressing the pressure spring. When the spring 703 is compressed, the mounting shaft 602 can be opened from the slot 51, allowing for quick disassembly of the heater housing 1. The elasticity of the spring 703 enhances the clamping force, ensuring the heater housing 1 is securely fixed. By rotating the internal thread knob 701, the positions of the ring 702, the spring 703, and the retaining ring 704 on the surface of the mounting shaft 602 can be adjusted. This allows for adjustment of the amount of compression of the spring 703 when fixing the heater housing 1. According to the formula for calculating elastic force, the elastic force is proportional to the amount of compression, thus adjusting the stability of the heater housing 1 fixed on the pipeline. like Figure 3 and Figure 4 As shown, in some practical applications, when the heater housing 1 is fixed to the surface of the pipe and the mounting shaft 602 is located in the slot 51, the end of its retaining ring 704 is tightly fitted to the surface of the second connecting plate 5. At this time, the pressure spring 703 is compressed and is used to tighten and fix the heater housing 1 to the pipe under the elastic force of the pressure spring 703.

[0026] More specifically, under the elastic force of the pressure spring 703, the retaining ring 704 applies a continuous clamping force to the second connecting plate 5, thereby tightening and fixing the heater housing 1 to the pipeline, ensuring the tightness and stability of the connection, preventing the heater housing 1 from loosening or falling off during use, and ensuring the safe and reliable operation of the heater.

[0027] In another embodiment, a rotatable internal thread knob 701 causes the ring 702, the pressure spring 703, and the retaining ring 704 to move along the surface of the mounting shaft 602. As the screw-in depth increases, the pressure spring 703 is compressed, generating elastic force, which causes the retaining ring 704 to press tightly against the surface of the second connecting plate 5, thereby clamping and fixing the heater housing 1. When disassembly is required, the internal thread knob 701 is rotated in the opposite direction to restore the pressure spring 703 to its original length and cause the ring 702, the pressure spring 703, and the retaining ring 704 to move in the opposite direction, thereby enabling quick disassembly and installation of the heater housing 1.

[0028] In summary: By inserting the connector 6 into the slot 51 on the surface of the second connecting plate 5, and through the spring-loaded quick-release assembly 7, the heater housing 1 can be quickly installed and removed from the surface of the pipe. When installation is required, align the connector 6 with the slot 51 and insert it. Before inserting the connector 6 into the slot 51, the installer needs to pull the movable part of the spring-loaded quick-release assembly 7 to compress its elastic part. After the connector 6 is inserted into the slot 51, the elastic part of the spring-loaded quick-release assembly 7 allows the spring-loaded quick-release assembly 7 to move freely. The part contacts the surface of the second connecting plate 5. Under the elastic force of the elastic part of the spring-loaded quick-release assembly 7, the heater housing 1 can be installed. Conversely, if it is to be disassembled, simply pull the movable part of the spring-loaded quick-release assembly 7 to compress the elastic part and release the connecting seat 6. The whole operation is convenient and efficient, which facilitates the installation and disassembly of the heater housing 1. The spring-loaded quick-release assembly 7 can move axially on the surface of the connecting seat 6, thereby enabling control of the pressure applied by the elastic part when the spring-loaded quick-release assembly 7 is compressed.
