Description

Technical Field

[0001] This application relates to the field of thermal power boiler technology, and in particular to heat recovery electric boilers that are easy to maintain. Background Technology

[0002] As is well known, in the fields of thermal power generation and industrial production, electric boilers, as core energy conversion equipment, need to convert electrical energy into heat energy to generate steam, providing power support for power generation systems or production processes. With the deepening of the concept of energy conservation and environmental protection, heat recovery electric boilers with heat recovery functions have gradually become the mainstream. By recovering the waste heat generated during equipment operation and reusing it, they effectively reduce energy loss, meet the green development needs of modern industry, and have been widely used in many fields such as power, chemical industry, and heating.

[0003] Currently, in related technologies, a search reveals that a utility model patent with publication number CN219640221U discloses a thermal power generation boiler that can recover heat energy. The equipment includes a base plate, support rods, boiler body, power generation equipment, and installation box. By recovering the heat from the exhaust gas and residue generated by boiler combustion, it achieves efficient energy utilization and solves the problem of energy waste in traditional electric boilers to a certain extent.

[0004] Regarding the aforementioned technologies, the applicant has found that existing heat recovery components of heat recovery electric boilers, such as waste heat exchange tubes and heat collection chambers, are generally installed inside the boiler body or in a sealed installation box. The installation gaps between the components are small, and the connection structure is complex. When the waste heat exchange tubes become blocked or leak, operators must first disassemble multiple layers of the outer shell and remove surrounding related components before they can access the component to be repaired. This not only involves cumbersome operating procedures but also easily causes collision damage to surrounding normal components during disassembly, increasing additional maintenance costs. This has certain limitations in use, seriously prolongs the downtime for equipment maintenance, and affects production progress.

[0005] Therefore, it is necessary for us to propose a heat recovery electric boiler that is easy to maintain. Utility Model Content

[0006] The purpose of this invention is to provide a heat recovery electric boiler that is easy to maintain, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: Heat recovery electric boilers that are easy to maintain include: Base; The boiler body is fixedly installed on the base, and a control panel is provided at one end of the boiler body, and the control panel is provided with multiple control buttons; The mounting plate is detachably connected to the base, and a vertical plate is fixedly connected to the mounting plate. Multiple heat recovery pipes are detachably connected to the vertical plate, and both ends of the heat recovery pipes are detachably connected to transmission pipes, which are connected to the inner cavity of the boiler body. An input pipe is provided at one end of the boiler body; An output pipe is provided at one end of the boiler body, and an installation ring is provided at the other end of the output pipe; A support assembly disposed within the base for supporting the base in its place of use.

[0008] As a further embodiment of this utility model: the support assembly includes multiple support columns, each of which is disposed in the base through a connecting groove, and the other end of each support column is fixedly connected to a support seat.

[0009] As a further improvement of this utility model, the bottom of each of the multiple support seats is provided with an anti-slip rubber pad.

[0010] The heat recovery electric boiler that is easy to maintain according to the claim is characterized in that: the mounting plate is detachably connected to the base by a plurality of mounting bolts.

[0011] As a further improvement of this utility model, the heat recovery pipes are all detachably connected to the upright plate via snap-fit ​​components.

[0012] As a further improvement of this utility model, the heat recovery pipe is connected to the transmission pipe via a connecting ring.

[0013] As a further improvement of this utility model, a sealing cap is threaded onto the input pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The mounting plate is detachably connected to the base via mounting bolts. The heat recovery pipes on the upright plate can be quickly installed and removed using clips. The heat recovery pipes and transmission pipes are connected via connecting rings. During maintenance, the heat recovery pipes can be removed individually for cleaning and replacement without disassembling the boiler body or opening the clips and separating the connecting rings, greatly simplifying maintenance procedures and significantly shortening downtime. The multiple support columns and support seats with anti-slip pads of the support components ensure the stability of the boiler body and heat recovery components, preventing operational vibrations from affecting the sealing of component connections. The control panel and control buttons allow operators to accurately control boiler operating parameters. Combined with the waste heat recovery function of the heat recovery pipes, its overall structure is relatively simple. Compared with existing technologies, its overall structure has the advantages of "high-efficiency heat recovery - convenient maintenance - stable operation", thus meeting the needs of power, chemical and other fields for equipment continuity and convenient maintenance, thereby improving the cost-effectiveness of the equipment and demonstrating good overall practicality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Please see Figures 1-4 In this embodiment of the invention, the heat recovery electric boiler, which is easy to maintain, includes: Base 1; Boiler body 2, the boiler body 2 is fixedly installed on the base 1, and a control panel 3 is provided at one end of the boiler body 2, and multiple control buttons 4 are provided on the control panel 3; Mounting plate 5 is detachably connected to base 1, and a vertical plate 6 is fixedly connected to mounting plate 5. Multiple heat return pipes 7 are detachably connected to vertical plate 6. Both ends of heat return pipes 7 are detachably connected to transmission pipes 8, which are connected to the inner cavity of boiler body 2. Input pipe 9 is located at one end of boiler body 2; Output pipe 10 is provided at one end of boiler body 2, and an installation ring 11 is provided at the other end of output pipe 10; A support assembly is disposed within the base 1 and is used to support the base 1 in its place of use.

[0020] This easy-to-maintain heat recovery electric boiler, during use, uses a support assembly. Multiple support columns 12 and support bases 13 work together to support the base 1 in the operating position. Then, the equipment is started and parameters are set. Using the control buttons 4 on the control panel 3, the operating parameters of the boiler body 2 (such as heating temperature and steam pressure) are set according to actual heating needs. Simultaneously, the waste heat recovery function of the regenerator pipe 7 is activated. The waste heat generated during the operation of the boiler body 2 enters the regenerator pipe 7 through the transmission pipe 8. After heat recovery through the regenerator pipe 7, it is returned to the boiler body 2 for recycling, achieving efficient energy utilization. During operation... Operators regularly monitor the equipment's operating status through the control panel 3 to ensure that there are no leaks in the heat recovery pipe 7 and the transmission pipe 8, and that the parameters are normal. When it is necessary to repair the heat recovery components (such as blockage or leakage in the heat recovery pipe 7), the boiler body 2 is shut down through the control panel 3 first. After the equipment has cooled down, if the heat recovery pipe 7 needs to be repaired as a whole, the mounting bolts 15 of the mounting plate 5 on the base 1 can be unscrewed, and the mounting plate 5, together with the upright plate 6 and the heat recovery pipe 7, can be removed as a whole. If only a single heat recovery pipe 7 needs to be repaired, the corresponding retaining part 16 of the heat recovery pipe 7 can be opened directly, and the connecting ring 17 between it and the transmission pipe 8 can be separated, so that the heat recovery pipe 7 can be taken out separately for cleaning or replacement.

[0021] exist Figure 1-3 The support assembly includes multiple support columns 12, each of which is installed in the base 1 via a connecting groove. The other end of each support column 12 is fixedly connected to a support seat 13, and the bottom of each support seat 13 is provided with an anti-slip pad 14.

[0022] This heat recovery electric boiler, which is easy to maintain, has a structure in which the support column 12 is rigidly connected to the base 1 via the connecting groove. This allows the overall weight of the boiler body 2 and the heat recovery components to be evenly transferred to the support base 13, preventing the base 1 from deforming due to uneven local stress and ensuring the overall stability of the equipment. The support base 13 increases the contact area with the ground, and together with the bottom anti-slip rubber pad 14, it enhances friction and can effectively resist external forces during boiler operation, preventing the equipment from slipping or tilting.

[0023] exist Figure 1-4 In the middle: the mounting plate 5 is detachably connected to the base 1 by multiple mounting bolts 15, the heat recovery pipes 7 are all detachably connected to the vertical plate 6 by clamping parts 16, the heat recovery pipes 7 are connected to the transmission pipe 8 by connecting rings 17, and the input pipe 9 is threaded with a sealing cap 18.

[0024] It should also be noted that the detachable connection between the mounting plate 5 and the base 1 allows the mounting plate 5, along with the upright plate 6 and the regenerator pipe 7, to be removed as a whole when the heat recovery assembly needs to be overhauled by unscrewing the mounting bolts 15, without disassembling the boiler body 2, greatly simplifying the operation. The regenerator pipe 7 is individually fixed by the clamping part 16, and with the connection design of the connecting ring 17 and the transmission pipe 8, when overhauling a single regenerator pipe 7, it is only necessary to open the corresponding clamping part 16 and separate the connecting ring 17 to remove it, avoiding damage to other normal components.

[0025] In this embodiment, the boiler body 2 is a commercially available device known to those skilled in the art. It can be customized or selected according to actual needs. Here, we are only using it without making any structural or functional improvements. We will not go into details here. The boiler body 2 is equipped with a matching control switch. The installation position of the control switch is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0026] The implementation principle of the heat recovery electric boiler in this application embodiment, which facilitates maintenance, is as follows: First, the base 1 is supported and placed in the usage position through the cooperation of multiple support columns 12 and support base 13. Then, the detachable structure design facilitates maintenance. The mounting plate 5 is detachably connected to the base 1 by mounting bolts 15. When the entire heat recovery assembly needs to be overhauled, the mounting plate 5, along with the upright plate 6 and the heat recovery pipe 7, can be directly removed without disassembling the boiler body 2. The heat recovery pipe 7 is individually fixed to the upright plate 6 by the clamping part 16 and is connected to the transmission pipe 8 by the connecting ring 17. When overhauling a single heat recovery pipe 7, it is only necessary to open the corresponding clamping part 16 and separate the connecting ring 17 to remove it without touching other normal parts, thus completely solving the problem of traditional heat recovery assemblies being too tightly installed. The complex connection and shut-off design significantly reduces downtime for maintenance, lowers repair costs and the risk of component damage. Furthermore, through multi-component collaboration, efficient heat recovery and equipment protection are achieved. Waste heat generated during the operation of the boiler body 2 enters the regenerator pipe 7 via the transmission pipe 8. After heat recovery, the regenerator pipe 7 returns the heat energy to the boiler body 2 for recycling, improving energy efficiency. The threaded sealing cap 18 on the input pipe 9 can seal the pipe opening when the equipment is idle or under maintenance, preventing dust and impurities from entering the inner cavity and contaminating the pipes and boiler body 2, ensuring internal cleanliness. The control panel 3 and control buttons 4 allow operators to accurately set operating parameters and monitor the equipment status in real time, ensuring that heat recovery and boiler operating parameters match, thus avoiding energy waste.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
