Description

Technical Field

[0001] This utility model relates to the field of electric furnace heat exchanger technology, and in particular to a staged high-efficiency cooling medium-frequency electric furnace heat exchanger. Background Technology

[0002] An electric furnace heat exchanger is a device used to transfer heat in an electric furnace system. Its main function is to transfer heat from a hot fluid to a cold fluid to meet specific process requirements. Heat exchangers typically consist of pipes and a container, and heat exchange occurs through both conduction and convection. The working principle of a heat exchanger is based on these two processes. Heat conduction occurs through a heat transfer surface (such as a plate or pipe); when two fluids pass over this surface, heat is transferred from one fluid to the other. Convection, on the other hand, achieves heat transfer through the flow of fluids, including forced convection and natural convection.

[0003] Most of the staged high-efficiency cooling medium-frequency electric furnace heat exchangers on the market are prone to heat exchange plate damage and malfunction after long-term use, thus requiring maintenance of the heat exchange plates. In addition, the heat exchange plates inside the existing medium-frequency electric furnace heat exchangers are welded as an integral structure with the medium-frequency electric furnace heat exchanger, making it impossible to disassemble and maintain the heat exchange plates, thereby increasing the labor intensity of operators. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the above or existing technologies, most of the staged high-efficiency cooling medium-frequency electric furnace heat exchangers on the market are prone to heat exchange plate damage and failure after long-term use, thus requiring maintenance of the heat exchange plates. At the same time, the heat exchange plates inside the existing medium-frequency electric furnace heat exchangers are welded as an integral structure with the medium-frequency electric furnace heat exchanger, making it impossible to disassemble and maintain the heat exchange plates, thereby increasing the labor intensity of operators. Therefore, this utility model is proposed.

[0006] Therefore, the purpose of this invention is to provide a staged, high-efficiency cooling medium-frequency electric furnace heat exchanger.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a staged high-efficiency cooling medium-frequency electric furnace heat exchanger, including a mounting frame, a fixing frame is installed at one end of the mounting frame that is close to each other, and a mounting groove is opened at one end of the fixing frame that is close to each other. A limit hole is opened on the side wall of the mounting groove. A heat exchange plate body is provided at one end of the fixing frame that is close to each other, and a heat exchange tube is opened inside the heat exchange plate body. An installation and disassembly assembly is provided on one side wall of the heat exchange plate body.

[0008] As a preferred embodiment of the graded high-efficiency cooling medium-frequency electric furnace heat exchanger of this utility model, the installation and disassembly assembly includes an installation block, which is fixedly installed at the top and bottom of the heat exchange plate body. The installation block has a first groove inside, and guide rails are installed at the top and bottom of the first groove. A guide block is provided inside the guide rail, and a limiting plate that penetrates the first groove is installed at the end of the guide block away from the guide rail.

[0009] As a preferred embodiment of the graded high-efficiency cooling medium-frequency electric furnace heat exchanger of this utility model, wherein: the installation and disassembly assembly has a second groove inside, and the bottom end of the second groove has a connecting hole that communicates with the first groove.

[0010] As a preferred embodiment of the graded high-efficiency cooling medium-frequency electric furnace heat exchanger of this utility model, wherein: a connecting rod is installed at the top of the limiting plate through the connecting hole and extending into the second groove, and a push rod is installed on the side wall of the connecting rod, and a protective sleeve is installed on the outer wall of the push rod.

[0011] As a preferred embodiment of the graded high-efficiency cooling medium-frequency electric furnace heat exchanger of this utility model, a high-pressure spring body is installed on the side wall of one end of the first groove, and one end of the high-pressure spring body is fixedly connected to the side wall of the limiting plate.

[0012] In a preferred embodiment of the graded high-efficiency cooling medium-frequency electric furnace heat exchanger of this utility model, the limiting plate and the limiting hole are engaged with each other, and the limiting plate is rectangular in shape.

[0013] As a preferred embodiment of the graded high-efficiency cooling medium-frequency electric furnace heat exchanger of this utility model, the material of the heat exchange plate body is copper alloy, and the thickness of the heat exchange plate body is 0.2-0.3cm.

[0014] The beneficial effects of this utility model of a staged high-efficiency cooling medium-frequency electric furnace heat exchanger are as follows: Firstly, the installation block and the installation groove cooperate with each other, and the guide rail and the guide block cooperate with each other, so that the push rod is pushed to drive the connecting rod and the limiting plate to slide inside the guide rail through the guide block and squeeze the high-pressure spring body to deform, thereby allowing the limiting plate to enter the interior of the first groove. The limiting plate is engaged with the installation block, and the elastic recovery of the high-pressure spring body causes the limiting plate to engage with the limiting hole, thereby facilitating the operator to disassemble and repair the heat exchange plate body, thus making the operation easier.

[0015] The beneficial effects of this utility model of a graded high-efficiency cooling medium-frequency electric furnace heat exchanger are as follows: Firstly, the heat exchange plate body is made of copper alloy, thereby improving the heat exchange effect of the heat exchange plate body. Secondly, the limiting plate engages with the limiting holes opened in the installation slots at different distances, thereby allowing multiple sets of heat exchange plate bodies to be installed as needed, thus improving the heat exchange effect of the medium-frequency electric furnace heat exchanger.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1: Refer to Figures 1-6 This is the first embodiment of the present utility model. This embodiment provides a staged high-efficiency cooling medium-frequency electric furnace heat exchanger, which can achieve the same results as most staged high-efficiency cooling medium-frequency electric furnace heat exchangers on the market. However, during long-term use, the heat exchange plates are prone to damage and failure, so the heat exchange plates need to be repaired. At the same time, the heat exchange plates inside the existing medium-frequency electric furnace heat exchangers are welded as an integral structure with the medium-frequency electric furnace heat exchanger, so it is impossible to disassemble and repair the heat exchange plates, thus increasing the labor intensity of the operators. The heat exchange plate heat exchanger includes a mounting frame 1, a fixing frame 2 is installed at one end of the mounting frame 1, and a mounting groove 3 is opened at one end of the fixing frame 2. The side wall of the mounting groove 3 is provided with a limit hole 301. An installation and disassembly assembly 5 is provided on one side wall of the heat exchange plate body 4.

[0029] The mounting and disassembly assembly 5 includes a mounting block 501, which is fixedly mounted on the top and bottom of the heat exchange plate body 4. A first groove 502 is formed inside the mounting block 501, and guide rails 503 are mounted on both the top and bottom of the first groove 502. A guide block 504 is provided inside the guide rail 503, and a limiting plate 505 penetrating the first groove 502 is mounted on the end of the guide block 504 away from the guide rail 503. A second groove 506 is formed inside the mounting and disassembly assembly 5, and a limiting plate 505 is formed at the bottom of the second groove 506, which is connected to the first groove 502. The groove 502 is connected to the connecting hole 507. The top of the limiting plate 505 is equipped with a connecting rod 508 that extends through the connecting hole 507 and into the second groove 506. A push rod 509 is installed on the side wall of the connecting rod 508. A protective sleeve is installed on the outer wall of the push rod 509. A high-pressure spring body 5010 is installed on the side wall of one end of the first groove 502. One end of the high-pressure spring body 5010 is fixedly connected to the side wall of the limiting plate 505. The limiting plate 505 and the limiting hole 301 are engaged with each other. The shape of the limiting plate 505 is rectangular.

[0030] The specific working principle is as follows: when it is necessary to install and disassemble the heat exchange plate body 4, the installation block 501 cooperates with the installation groove 3, and the guide rail 503 and guide block 504 cooperate with each other to push the push rod 509, which drives the connecting rod 508 and the limiting plate 505 to slide inside the guide rail 503 through the guide block 504 and squeeze the high pressure spring body 5010 to deform, so that the limiting plate 505 enters the interior of the first groove 502, and the limiting plate 505 is engaged with the installation block 501. Then, the high pressure spring body 5010 elastically returns to its original state and drives the limiting plate 505 to engage with the limiting hole 301, which makes it convenient for the operator to disassemble and repair the heat exchange plate body 4, thus facilitating the operation.

[0031] Example 2: Refer to Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a staged high-efficiency cooling medium-frequency electric furnace heat exchanger, which can achieve the same results as most staged high-efficiency cooling medium-frequency electric furnace heat exchangers on the market. However, during long-term use, the heat exchange plates are prone to damage and failure, thus requiring maintenance. In addition, the heat exchange plates inside the existing medium-frequency electric furnace heat exchangers are welded as an integral structure, making it impossible to disassemble and maintain the heat exchange plates, thereby increasing the labor intensity of the operators. The fixed frame 2 is provided with heat exchange plate body 4 at one end close to each other, and heat exchange tubes 401 are opened inside the heat exchange plate body 4. The material of the heat exchange plate body 4 is copper alloy, and the thickness of the heat exchange plate body 4 is 0.2-0.3cm.

[0032] The specific working principle is as follows: First, the heat exchange plate body 4 is made of copper alloy, which improves the heat exchange effect of the heat exchange plate body 4. At the same time, the limiting plate 505 engages with the limiting holes 301 opened in the installation slots 3 at different distances, so that multiple sets of heat exchange plate bodies 4 can be installed as needed, thereby improving the heat exchange effect of the medium frequency electric furnace heat exchanger.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
