Description

Technical Field

[0001] This application relates to the field of heating core rod technology, specifically a modular assembled heating core rod structure for reheaters. Background Technology

[0002] During the operation of a thermal system, the reheater is responsible for the secondary heating of steam, and the heating core rod is one of the core components for the reheater to achieve the heating function. Its performance affects the overall operating efficiency and stability of the reheater.

[0003] A heating rod according to application number CN202320053927.6 includes a controller and a power cord. The power cord is electrically connected to the controller. A first heating rod is fixedly connected to the bottom of the controller. A connecting block is fixedly connected to the bottom of the first heating rod. A mating block is in close contact with the bottom of the connecting block. A second heating rod is fixedly connected to the bottom of the mating block. Protrusions are fixedly connected to the front and rear sides of the top of the mating block and extend to the top of the connecting block. Fixing blocks are fixedly connected to the front and rear sides of the top of the connecting block. A cavity is formed inside the front fixing block. A clamping component is provided on the left side of the inner wall of the cavity, and a pulling component is provided on the right side of the inner wall of the cavity.

[0004] However, most heating cores currently used in reheaters adopt an integral design, and their heating power is relatively fixed. They cannot be flexibly adjusted according to the actual heating power required. The aforementioned heating core has certain shortcomings. Although the heating core can be adjusted in length, the heating core module cannot be disassembled. This means that when the heating power does not match the operating conditions, the heating core cannot be replaced, which may result in insufficient heating or overheating.

[0005] Therefore, it is necessary to provide a modular, assembled heating core structure for reheaters to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a modular assembled heating core structure for reheaters, which solves the problem that most heating cores adopt an integral design, and their heating power is relatively fixed and cannot be flexibly adjusted according to the actual required heating power.

[0008] The technical solution adopted by this application to solve its technical problem is: a modular assembled heating core rod structure for a reheater, including a connector and a mounting plate. The connector is threaded with several bolts on its inner side. The mounting plate is located directly below the connector. The bottom end of the mounting plate is connected to four mating blocks. Each of the four mating blocks is provided with a locking component. Each of the four mating blocks has a through groove on its inner side. A heating core rod body is locked and connected to the inner side of every two through grooves. Each of the two heating core rod bodies has two locking slots on its inner side. The surfaces of the four engagement components are respectively connected to the inner sides of the four docking blocks for engaging and positioning the two heating core bodies.

[0009] Furthermore, each of the four engaging components includes a slide rod, a first inner contraction spring, and a second inner contraction spring. The four slide rods are slidably disposed on the inner side of the four mating blocks. One end of each of the four slide rods is connected to a locking block, and the other end of each of the four slide rods is connected to a connecting block. The four first inner contraction springs are respectively sleeved on the outer side of the four slide rods, and the four second inner contraction springs are respectively sleeved on the outer side of the four slide rods.

[0010] Furthermore, the surfaces of the four card blocks are respectively engaged with the inner sides of the four card slots.

[0011] Furthermore, the four card blocks are symmetrically arranged in pairs on both the front and rear sides of the vertical center line of the mounting plate.

[0012] Furthermore, the two ends of the four first internal contraction springs are respectively connected to the surfaces of the four locking blocks and the inner walls of the four docking blocks.

[0013] Furthermore, the two ends of the four second internal contraction springs are respectively connected to the surfaces of the four connecting blocks and the surfaces of the four mating blocks.

[0014] Furthermore, the mounting plate is detachably connected to the connector by a number of bolts.

[0015] The beneficial effects of this application are as follows: The modular assembled heating core structure for reheaters provided by this application facilitates the separation of corresponding locking blocks by pulling outwards on the opposing connecting blocks, thereby reserving space for the locking of the heating core body. The contraction action of the first and second inner contraction springs facilitates the locking of the locking blocks after the heating core body is locked into the docking block, allowing them to pop out and engage with the locking slot, thus facilitating the locking and fixing of the heating core body. It also facilitates the replacement of heating core bodies with different power ratings to adjust the overall heating power, improving adaptability to diverse operating requirements. Several bolts facilitate the locking and fixing of the mounting plate and the connector, making installation and disassembly convenient. This also facilitates the independent transportation of the connector and the heating core body, reduces damage to components through packaging, and provides auxiliary protection for the heating core body and the connector.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figure 1-5 As shown, this application provides a modular assembled heating core structure for a reheater, including a connector 1 and a mounting plate 4. The inner side of the connector 1 is threaded with several bolts 3. The mounting plate 4 is located directly below the connector 1 for easy disassembly and installation. The bottom end of the mounting plate 4 is connected to four mating blocks 5. Each of the four mating blocks 5 is provided with a locking component 2. The inner side of each of the four mating blocks 5 is provided with a through groove 6. The inner side of every two through grooves 6 is locked with a heating core body 7. By disassembling and replacing the heating core body 7, it is easy to adjust the overall heating power and improve the adaptability to diverse operating requirements. The inner side of each of the two heating core bodies 7 is provided with two locking slots 8. The surfaces of the four engaging components 2 are respectively connected to the inner sides of the four mating blocks 5 for engaging and positioning the two heating core bodies 7.

[0021] Each of the four engaging components 2 includes a slide rod 21, a first inner retraction spring 24, and a second inner retraction spring 25. The four slide rods 21 are slidably disposed on the inner side of the four mating blocks 5. One end of each of the four slide rods 21 is connected to a locking block 22, which facilitates engagement with the corresponding locking slot 8. The other end of each of the four slide rods 21 is connected to a connecting block 23, which facilitates hand gripping. The four first inner retraction springs 24 are respectively sleeved on the outer side of the four slide rods 21, and the four second inner retraction springs 25 are respectively sleeved on the outer side of the four slide rods 21.

[0022] The surfaces of the four locking blocks 22 engage with the inner sides of the four locking slots 8 respectively, which facilitates the locking and fixing of the heating core rod body 7.

[0023] Four locking blocks 22 are symmetrically arranged in pairs on the front and back sides of the vertical center line of the mounting plate 4, which facilitates symmetrical positioning of the heating core rod body 7 and prevents the heating core rod body 7 from falling off or becoming crooked.

[0024] The two ends of the four first internal contraction springs 24 are respectively connected to the surfaces of the four locking blocks 22 and the inner walls of the four docking blocks 5, so as to provide a pushing force for the locking blocks 22.

[0025] The two ends of the four second internal contraction springs 25 are respectively connected to the surfaces of the four connecting blocks 23 and the four mating blocks 5, which helps to improve the stability of the engagement between the locking block 22 and the locking groove 8.

[0026] The mounting plate 4 is detachably connected to the connector 1 by several bolts 3, making it easy to disassemble and replace.

[0027] Working principle: First, when it is necessary to install the connector 1, the mounting plate 4 and the heating core rod body 7 as a whole, pull the opposite connecting block 23 outward, so that the corresponding two locking blocks 22 separate towards each other, thereby reserving space for the heating core rod body 7. Then, insert the two heating core rod bodies 7 into the interior of the corresponding docking block 5 from top to bottom, so as to engage with the through groove 6. Then, release the four connecting blocks 23, so that the four locking blocks 22 retract inward under the strong contraction of the corresponding first inner contraction spring 24 and the second inner contraction spring 25, and engage with the locking groove 8 opened on the surface of the heating core rod body 7, thereby limiting and fixing the heating core rod body 7. After the heating core rod body 7 is installed and fixed between the mounting plate 4 and the mounting plate 4, the mounting plate 4 and the connector 1 can be locked and fixed by several bolts 3. This facilitates both installation and disassembly, and makes it easy to disassemble and replace the heating core rod body 7 with heating core rod bodies 7 of different power to adjust the overall heating power, thereby improving adaptability to diverse operating requirements. Furthermore, the detachable design of the connector 1, mounting plate 4 and heating core rod body 7 also facilitates the independent transportation of the connector 1 and heating core rod body 7, which is beneficial for packaging and reduces damage to components, thus providing auxiliary protection for the heating core rod body 7 and connector 1.

[0028] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
