Description

Technical Field

[0001] This utility model relates to the field of muffle furnace technology, and in particular to a sealed muffle furnace. Background Technology

[0002] A muffle furnace, also known as a box furnace, is a heating furnace with a box-shaped furnace chamber. During the entire heating process of heating, holding, and cooling products, the products remain stationary, and feeding and discharging occur through a single door or trough. It is also called an intermittent production furnace.

[0003] In practical applications, the existing muffle furnace technology has a relatively complete structure and function, which can basically meet the needs of daily use. However, the following problems still exist:

[0004] In actual use, the control panel is very easy to accidentally touch. Once the muffle furnace is accidentally touched, the internal temperature changes, which can easily damage the internal components and cause corresponding losses. At the same time, since the high temperature inside the muffle furnace is dissipated through the external shell, even if there are internal insulation measures, the temperature of the external shell will remain relatively high for a long time. This can easily cause the control panel to age faster due to long-term use in a high-temperature environment, thus affecting the overall service life.

[0005] Therefore, this utility model provides a sealed muffle furnace. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a sealed muffle furnace.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a sealed muffle furnace, comprising a furnace body, a cover plate rotatably connected to one side of the outer surface of the furnace body, a fixing plate fixedly connected to one side of the outer surface of the cover plate, a threaded clamp rod threadedly connected to the inner wall of the fixing plate, a screw-hole clamping sleeve fixedly connected to one side of the outer surface of the furnace body, a control panel provided on one side of the furnace body, a rectangular ring block fixedly connected to one side of the cover plate, a rectangular ring groove formed on one side of the furnace body, and a furnace cavity formed on one side of the furnace body; an anti-touch heat dissipation structure provided on one side of the outer surface of the furnace body, the anti-touch heat dissipation structure including a protective frame, a second motor fixedly connected to one side of the outer surface of the protective frame, an active rod fixedly connected to the output end of the second motor, and an active fan blade fixedly connected to one end of the active rod; an auxiliary sealing structure provided on the back of the furnace body, the auxiliary sealing structure including a rubber sealing plate, the rubber sealing plate consisting of a rectangular ring-shaped rubber plate on the front and a U-shaped rubber plate fixedly connected to one side therewith.

[0008] In a preferred embodiment, a first rectangular frame is fixedly connected to one side of the furnace body. A first motor is fixedly connected to the top of the outer surface of the first rectangular frame. A first screw is fixedly connected to the output end of the first motor. A first screw hole block is threadedly connected to the outer surface of the first screw. The outer surface of the first screw hole block is slidably connected to the inner wall of the first rectangular frame. A rectangular through groove is formed on one side of the outer surface of the first rectangular frame. A sliding rod is slidably connected to the inner wall of the rectangular through groove. One end of the sliding rod is fixedly connected to one side of the first screw hole block, and the other end of the sliding rod is fixedly connected to a protective frame. A driven rod is rotatably connected to the inner wall of the protective frame. A driven fan blade is fixedly connected to one end of the driven rod. A driving pulley is fixedly connected to the outer surface of the driving rod, and a driven pulley is fixedly connected to the outer surface of the driven rod. A transmission belt is rotatably provided on the outer surfaces of the driving pulley and the driven pulley.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the first screw and the first screw hole block, the protective frame can be driven to move up and down, thereby protecting the control panel and preventing accidental contact. At the same time, under the action of the active pulley and the driven pulley, the active rod and the driven rod can be driven to rotate, thereby driving the active fan blade and the driven fan blade to rotate, thereby providing auxiliary heat dissipation for the control panel.

[0010] In a preferred embodiment, a second rectangular frame is fixedly connected to the rear side of the outer surface of the furnace body, a third motor is fixedly connected to the bottom of the outer surface of the second rectangular frame, a second screw is fixedly connected to the output end of the third motor, a second screw hole block is threadedly connected to the outer surface of the second screw, an auxiliary connecting rod is fixedly connected to one side of the outer surface of the second screw hole block, and one end of the auxiliary connecting rod is fixedly connected to a rubber sealing plate.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the second screw and the second screw hole block, the rubber sealing plate can be driven to move, so that the rubber sealing plate can seal the connection between the cover plate and the furnace body, thereby improving the overall sealing performance.

[0012] In a preferred embodiment, the inner wall of the rubber sealing plate is provided with a through groove.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the through-plate groove, the rubber sealing plate can pass through the fixed plate, thereby avoiding the fixed plate from obstructing the movement of the through-plate groove. At the same time, due to the rubber's easily deformable properties, the rubber sealing plate can perfectly fit the cover plate and the furnace body, thereby achieving a sealing effect.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up an anti-touch heat dissipation structure, the protective frame can be moved under the action of the first screw and the first screw hole block, thereby protecting the control panel and preventing accidental operation from the outside. At the same time, under the action of the active fan blades and driven fan blades, the airflow around the control panel can be disturbed, thereby increasing the airflow speed and accelerating the heat dissipation of the surrounding area, thus improving the overall heat dissipation effect of the control panel. By setting up an auxiliary sealing structure, the rubber sealing plate can be moved under the action of the second screw and the second screw hole block, thereby sealing the connection between the cover plate and the furnace body, thus improving the overall sealing performance.

[0026] 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.

[0027] like Figures 1-5 As shown, this embodiment provides a technical solution: a sealed muffle furnace, including a furnace body 1, a cover plate 2 rotatably connected to one side of the outer surface of the furnace body 1, a fixing plate 3 fixedly connected to one side of the outer surface of the cover plate 2, a threaded clamp 4 threadedly connected to the inner wall of the fixing plate 3, a screw hole clamp 5 fixedly connected to one side of the outer surface of the furnace body 1, a control panel 6 provided on one side of the furnace body 1, a rectangular ring block 9 fixedly connected to one side of the cover plate 2, a rectangular ring groove 10 opened on one side of the furnace body 1, and a furnace cavity 11 opened on one side of the furnace body 1; an anti-touch heat dissipation structure 7 is provided on one side of the outer surface of the furnace body 1, the anti-touch heat dissipation structure 7 includes a protective frame 78, a second motor 79 fixedly connected to one side of the outer surface of the protective frame 78, an active rod 710 fixedly connected to the output end of the second motor 79, and an active fan blade 714 fixedly connected to one end of the active rod 710; an auxiliary sealing structure 8 is provided on the back of the furnace body 1, the auxiliary sealing structure... The structure 8 includes a rubber sealing plate 86, which consists of a rectangular ring-shaped rubber plate on the front and a U-shaped rubber plate fixedly connected to one side thereon. By setting an anti-touch heat dissipation structure 7, the protective frame 78 can be moved under the action of the first screw 73 and the first screw hole block 74, thereby protecting the control panel 6 and preventing accidental operation from the outside. At the same time, under the action of the active fan blade body 714 and the driven fan blade body 715, the air flow around the control panel 6 can be disturbed, thereby increasing the air flow speed and accelerating the heat dissipation of the surrounding area, thus improving the overall heat dissipation effect of the control panel 6. By setting an auxiliary sealing structure 8, the rubber sealing plate 86 can be moved under the action of the second screw 83 and the second screw hole block 84, thereby sealing the connection between the cover plate 2 and the furnace body 1, thereby improving the overall sealing performance.

[0028] Going a step further, such as Figure 4As shown: A first rectangular frame 71 is fixedly connected to one side of the furnace body 1. A first motor 72 is fixedly connected to the top of the outer surface of the first rectangular frame 71. A first screw 73 is fixedly connected to the output end of the first motor 72. A first screw hole block 74 is threadedly connected to the outer surface of the first screw 73. The outer surface of the first screw hole block 74 is slidably connected to the inner wall of the first rectangular frame 71. A rectangular through groove 76 is opened on one side of the outer surface of the first rectangular frame 71. A sliding rod 77 is slidably connected to the inner wall of the rectangular through groove 76. One end of the sliding rod 77 is fixedly connected to one side of the first screw hole block 74, and the other end of the sliding rod 77 is fixedly connected to a protective frame 78. A driven rod 712 is rotatably connected to the inner wall of the protective frame 78. One end of the driven rod 712 is fixedly connected to... The device includes a driven fan blade 715, a driven pulley 711 fixedly connected to the outer surface of the driven rod 710, and a driven pulley 713 fixedly connected to the outer surface of the driven rod 712. A transmission belt 75 is rotatably mounted on the outer surfaces of the driven pulley 711 and the driven pulley 713. Under the action of the first screw 73 and the first screw hole block 74, the protective frame 78 can be driven to move up and down, thereby protecting the control panel 6 and preventing accidental contact. At the same time, under the action of the driven pulley 711 and the driven pulley 713, the driven rod 710 and the driven rod 712 can be driven to rotate, thereby driving the driven fan blade 714 and the driven fan blade 715 to rotate, thereby providing auxiliary heat dissipation for the control panel 6.

[0029] The above solutions also have a problem: there is a gap at the connection between the cover plate 2 and the furnace body 1, which could easily lead to communication between the inside and the outside. Figure 5 As shown: In this scheme, a second rectangular frame 81 is fixedly connected to the rear side of the outer surface of the furnace body 1. A third motor 82 is fixedly connected to the bottom of the outer surface of the second rectangular frame 81. A second screw 83 is fixedly connected to the output end of the third motor 82. A second screw hole block 84 is threadedly connected to the outer surface of the second screw 83. An auxiliary connecting rod 85 is fixedly connected to one side of the outer surface of the second screw hole block 84. One end of the auxiliary connecting rod 85 is fixedly connected to the rubber sealing plate 86. Under the action of the second screw 83 and the second screw hole block 84, the rubber sealing plate 86 can be driven to move, so that the rubber sealing plate 86 can seal the connection between the cover plate 2 and the furnace body 1, thereby improving the overall sealing performance.

[0030] The above solution also has the problem that the fixing plate 3 will affect the movement of the rubber sealing plate 86, such as... Figure 5 As shown, the inner wall of the rubber sealing plate 86 has a through groove 87. Under the action of the through groove 87, the rubber sealing plate 86 can pass through the fixing plate 3, thereby avoiding the fixing plate 3 from obstructing the movement of the through groove 87. At the same time, due to the rubber deformation characteristics of the rubber sealing plate 86, it can perfectly fit the cover plate 2 and the furnace body 1, thereby achieving a sealing effect.

[0031] Working principle:

[0032] like Figure 1-5 As shown:

[0033] In use: Start the first motor 72 so that the first screw 73 can drive the first screw hole block 74 to move, which in turn can drive the protective frame 78 to move, thereby providing auxiliary protection for the control panel 6 and preventing accidental touch;

[0034] At this time, starting the second motor 79 can drive the drive rod 710 to rotate, which in turn drives the drive pulley 711 to rotate, which in turn drives the transmission belt 75 and the driven pulley 713 to rotate, which in turn drives the driven rod 712 to rotate, which in turn drives the drive fan blade 714 and the driven fan blade 715 to rotate, thereby providing auxiliary heat dissipation.

[0035] At this time, the third motor 82 is started, so that the second screw 83 can drive the second screw hole block 84 to move, which in turn can drive the auxiliary connecting rod 85 to move, which in turn can drive the rubber sealing plate 86 to move, which can then fit and fix with the cover plate 2 and the furnace body 1, thus achieving sealing.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
