Description

Technical Field

[0001] This utility model relates to the technical field of electric heating furnace components, and in particular to an installation structure for a heat insulation layer inside an electric heating furnace. Background Technology

[0002] A heating furnace is a device used to provide high temperatures, typically made of heat-resistant materials. It has various applications, including chemical reactions in laboratories, material handling, and metal smelting. Heating furnaces generally use metal heaters or resistance wires as the heat source, generating heat through electricity or combustion. They usually have an internal temperature control device to adjust the heating temperature as needed. Heating furnaces can also be equipped with insulation materials to reduce heat loss.

[0003] like Figure 4 The diagram shows the previous generation of thermal insulation layer installed inside an electric heating furnace. Multiple thermal insulation panels can be spliced ​​together end to end and then fixed inside the furnace body by multiple support bases and fasteners, forming a complete thermal insulation barrier inside the furnace body. However, this thermal insulation layer installation structure has the following shortcomings in actual use: Since multiple support bases are fixed inside the furnace body, when installing or removing the thermal insulation layer, operators need to take tools and reach into the furnace body to operate. Due to the limited space inside the furnace, the workload and difficulty of installing and removing the thermal insulation layer are relatively large, reducing the convenience and efficiency of thermal insulation layer installation.

[0004] In view of this, it is particularly important to design and manufacture a heat insulation board installation structure that enables tool-free and quick installation of the heat insulation layer into the furnace body, thereby improving the convenience and efficiency of heat insulation layer installation and removal. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the installation and dismantling of the insulation layer in the previous generation of electric heating furnaces was labor-intensive and difficult, and not convenient for actual installation and dismantling operations. Therefore, a new installation structure for the insulation layer in an electric heating furnace is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An installation structure for the heat insulation layer inside an electric heating furnace includes a furnace body and multiple heat insulation plates arranged in a ring array on the inside of the furnace body and connected end to end. A locking mechanism is provided between the inner side of the furnace body and the outer side of the multiple heat insulation plates for tool-free installation of the heat insulation plates on the inside of the furnace body.

[0007] As a further description of the above technical solution: The locking mechanism includes a dovetail block integrally fixed to the middle of the outer side of multiple heat insulation boards, a dovetail buckle fixed in a ring array inside the furnace body and engaged with the dovetail block, and a rotary lock part disposed between the dovetail block and the furnace body for locking the dovetail block to the inside of the dovetail buckle.

[0008] As a further description of the above technical solution: The rotary locking part includes a rotating hole in the middle of the dovetail insert, a rotating rod rotatably installed inside the rotating hole, multiple locking pins fixed at equal intervals outside the rotating rod and facing the furnace body, a limiting locking block fixed inside the furnace body and corresponding to the positions of the multiple locking pins, and a locking pin on the limiting locking block for laterally rotating and sliding into the horizontal locking groove.

[0009] As a further description of the above technical solution: A knob is installed at the upper end of the rotating rod, and an anti-deflection part is provided between the heat insulation plate and the upper end of the knob for locking the knob to prevent deflection.

[0010] As a further description of the above technical solution: The anti-deviation part includes an upper rotary groove located on the upper end of the heat insulation board and outside the knob, an anti-deviation buckle block rotatably installed between the upper rotary groove and the knob, and a limiting groove on the anti-deviation buckle block that engages with the knob.

[0011] As a further description of the above technical solution: One end of the heat insulation board is integrally fixedly connected to an outwardly protruding assembly block, and the other end of the heat insulation board is provided with an assembly slot that engages with the assembly block.

[0012] As a further description of the above technical solution: In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, the original heat insulation layer installation structure inside the electric heating furnace has been scientifically and rationally improved. A dovetail buckle, a limiting lock block, and a horizontal locking groove are installed inside the furnace body. Simultaneously, a dovetail buckle, a rotating rod, a locking post, and a knob are installed on the heat insulation plate. When the dovetail buckle on the heat insulation plate is positioned and slides into the dovetail slot inside the furnace body, the heat insulation plate is initially fixed in place within the furnace body. Then, when the knob is rotated 90° counterclockwise from its initial position, the locking post on the rotating rod can be horizontally screwed into the horizontal locking groove on the limiting lock block, further locking the heat insulation plate between the furnace body and the dovetail buckle. This structure enables tool-free and quick installation of the heat insulation plate and the furnace body, effectively reducing the workload and difficulty of installing or disassembling the heat insulation plate, thereby improving the convenience and efficiency of heat insulation layer installation and disassembly.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: an installation structure for the heat insulation layer inside an electric heating furnace, including a furnace body 1 and a plurality of heat insulation plates 2 arranged in a ring array inside the furnace body 1 and connected end to end. A locking mechanism is provided between the inner side of the furnace body 1 and the outer side of the plurality of heat insulation plates 2 for tool-free convenient installation of the heat insulation plates 2 inside the furnace body 1.

[0017] Specifically, such as Figure 1-3 As shown, the locking mechanism includes a dovetail plug 201 integrally fixed to the middle of the outer side of multiple heat insulation boards 2, a dovetail buckle 101 fixed in a ring array on the inner side of the furnace body 1 and engaged with the dovetail plug 201, and a rotary lock part disposed between the dovetail plug 201 and the furnace body 1 for locking the dovetail plug 201 to the inner side of the dovetail buckle 101.

[0018] The rotary locking part includes a rotating hole 202 in the middle of the dovetail insert 201, a rotating rod 4 rotatably installed inside the rotating hole 202, multiple locking pins 401 fixed at equal intervals outside the rotating rod 4 and facing the furnace body 1, a limiting locking block 102 fixed inside the furnace body 1 and corresponding to the positions of the multiple locking pins 401, and a horizontal locking groove 103 opened on the limiting locking block 102 for the locking pins 401 to rotate laterally and slide into the horizontal locking groove 103. When the locking pin 401 is screwed into the horizontal locking groove 103 of the limiting locking block 102, the dovetail insert 201 can be longitudinally locked and fixed in the dovetail buckle 101, thereby comprehensively limiting and locking the dovetail insert 201 that has slid into the dovetail buckle 101 between the furnace body 1 and the dovetail buckle 101.

[0019] Specifically, such as Figure 1-3 As shown, a knob 402 is installed on the upper end of the rotating rod 4, which facilitates the operator's grip and rotation adjustment of the rotating rod 4. An anti-deflection part for locking the knob 402 is provided between the heat insulation plate 2 and the upper end of the knob 402. The anti-deflection part includes an upper rotating groove 203 opened on the upper end of the heat insulation plate 2 and located outside the knob 402, an anti-deflection buckle 3 rotatably installed between the upper rotating groove 203 and the knob 402, and a limiting groove 301 opened on the anti-deflection buckle 3 and engaged with the knob 402. When the anti-deflection buckle 3 rotates inward into the upper rotating groove 203, the limiting groove 301 on the anti-deflection buckle 3 can engage with the knob 402 on the rotating rod 4, thereby performing anti-deflection limiting treatment on the rotating rod 4, which can effectively prevent the locking pin 401 on the rotating rod 4 from accidentally rotating away from the limiting locking block 102.

[0020] Specifically, such as Figure 1-3 As shown, one end of the heat insulation board 2 is integrally fixedly connected with an outwardly protruding assembly block 204, and the other end of the heat insulation board 2 is provided with an assembly slot 205 that engages with the assembly block 204.

[0021] Working principle: When using the insulation board 2, it needs to be installed into the furnace body 1. First, the operator can take the insulation board 2, then align the dovetail insert 201 on the insulation board 2 and insert it into the dovetail buckle 101 inside the furnace body 1. When the insulation board 2 is fully inserted into the furnace body 1, the insulation board 2 will be pre-positioned between the furnace body 1 and the dovetail buckle 101. Next, hold and rotate the knob 402 counterclockwise 90°. At this time, the rotating rod 4 will rotate counterclockwise within the rotating hole 202 of the dovetail insert 201. Rotate 90°, and the locking pin 401 on the rotating rod 4 can gradually enter the limiting locking block 102 through the horizontal locking groove 103, which can further lock and fix the heat insulation plate 2 between the furnace body 1 and the dovetail buckle 101. Finally, rotate the anti-deviation locking block 3 in the upper rotating groove 203 towards the heat insulation plate 2, and the limiting groove 301 on the anti-deviation locking block 3 can be positioned and locked on the knob 402, thereby locking the rotating rod 4 in the rotating hole 202 to prevent the rotating rod 4 from being accidentally deflected due to force, which would cause the heat insulation plate 2 to be released from its locked state.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
