[0001] This utility model relates to the technical field of carbon black experimental equipment, and in particular to a carbon black muffle furnace with safety protection function. Background Technology

[0002] A muffle furnace is a translation of the English word "muffle furnace." "Muffle" means package, and "furnace" refers to a furnace or melting vessel. A muffle furnace is a general-purpose heating device that uses resistance heating. Its heating elements are categorized as: electric heating wire muffle furnaces, silicon carbide rod muffle furnaces, and silicon molybdenum rod muffle furnaces. It has wide applications, commonly used in heat processing, industrial workpiece handling, and the cement and building materials industries for the heat processing or treatment of small workpieces. Carbon black muffle furnaces are commonly used to determine the ash content of samples, allowing for rapid and accurate determination of the ash content. During operation, the carbon black sheet must be laid flat on an independent heater, such as a crucible, before heating in the muffle furnace.

[0003] In existing technologies, when conducting experiments in a carbon black muffle furnace, users need to reach inside the furnace to remove the crucible. Due to the high temperature inside the muffle furnace, it is not convenient for users to directly remove the casting. Users need to use tools to remove it, which is quite troublesome, and this method may cause burns to the workers.

[0004] Therefore, this utility model proposes a carbon black muffle furnace with safety protection function. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a carbon black muffle furnace with safety protection functions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a carbon black muffle furnace with safety protection function, comprising a muffle furnace body, wherein a heating chamber is provided inside the muffle furnace body, a sliding groove is provided on the side wall of the heating chamber, a movable block is slidably connected to the inner wall of the sliding groove, a placement plate is fixedly connected to one end of the movable block, and a moving mechanism that cooperates with the placement plate is installed at the other end of the movable block.

[0007] Furthermore, the moving mechanism includes a sealing block that is fixedly connected to the rear side wall of the muffle furnace body. A screw is threadedly connected to the side wall of the sealing block, and a connecting block is threadedly connected to one end of the screw located inside the muffle furnace body.

[0008] Furthermore, the moving mechanism also includes a first V-shaped link hinged to the inner side of the sealing block, both ends of the first V-shaped link being hinged to a scissor lift, and a single hinge point of the scissor lift being rotatably connected to the top of the connecting block. One end of the scissor lift is hinged to a second V-shaped link, and one end of the second V-shaped link is hinged to the inner side of the movable block.

[0009] Furthermore, a rotating handle is fixedly connected to one end of the screw located outside the muffle furnace body.

[0010] Furthermore, a crucible placement groove is provided on the top of the placement plate.

[0011] Furthermore, the lower surface of the muffle furnace body is fixedly connected to support bases around all four sides, and a heating element is fixedly installed on the top of the muffle furnace body.

[0012] Furthermore, an insulation door is hinged to the front of the muffle furnace body, and a handle is fixedly connected to one side of the front of the insulation door.

[0013] This utility model has the following beneficial effects:

[0014] In use, this carbon black muffle furnace with safety protection features, through its placement plate, slide groove, and moving mechanism, allows the connecting block to move via a screw by rotating the handle. This drives the scissor lift to unfold or fold, thereby moving the placement plate and movable block along the slide groove to be moved outward from the interior of the muffle furnace. This makes it convenient to use, saves time and effort, and prevents operators from being burned when retrieving materials from the inside. It makes the device safer to operate and has a high level of safety protection. At the same time, it can maintain stability when moving the crucible containing carbon black along the slide groove, ensuring the stability of the crucible when it is moved out.

Detailed Implementation

[0020] Figures 1 to 3 As shown, a carbon black muffle furnace with safety protection function is disclosed, including a muffle furnace body 1. A heating chamber 5 is provided inside the muffle furnace body 1. A sliding groove 6 is provided on the side wall of the heating chamber 5. A movable block 9 is slidably connected to the inner wall of the sliding groove 6. A placement plate 7 is fixedly connected to one end of the movable block 9. The lower surface of the placement plate 7 is slidably connected to the inner wall of the heating chamber 5. A crucible placement groove 8 is provided on the top of the placement plate 7. A moving mechanism that cooperates with the placement plate 7 is installed on the other end of the movable block 9.

[0021] The moving mechanism includes a sealing block 10 that is fixedly connected to the rear side wall of the muffle furnace body 1. A screw 11 is threadedly connected to the side wall of the sealing block 10. A connecting block 14 is threadedly connected to one end of the screw 11 inside the muffle furnace body 1, while a rotating handle 12 is fixedly connected to the other end of the screw 11 outside the muffle furnace body 1. Rotating the rotating handle 12 can drive the screw 11 to rotate, and the rotation of the screw 11 will drive the connecting block 14 to move laterally.

[0022] The moving mechanism also includes a first V-shaped connecting rod 13 hinged to the inner side of the sealing block 10. Both ends of the first V-shaped connecting rod 13 are hinged to a scissor lift 15, and a single hinge point of the scissor lift 15 is rotatably connected to the top of the connecting block 14. One end of the scissor lift 15 is hinged to a second V-shaped connecting rod 16, and one end of the second V-shaped connecting rod 16 is hinged to the inner side of the movable block 9. When the connecting block 14 is displaced, it can drive the scissor lift 15 to unfold or fold, thereby driving the movable block 9 to slide along the inner wall of the slide groove 6, and then driving the placement plate 7 to move laterally, controlling the placement plate 7 to enter or move out of the muffle furnace body 1.

[0023] The first V-shaped link 13 and the second V-shaped link 16 are composed of two hinged links that can change their included angle. When the scissor lift 15 deforms as it moves with the connecting block 14, the first V-shaped link 13 and the second V-shaped link 16 can deform synchronously.

[0024] Support bases 4 are fixedly connected to the lower surface of the muffle furnace body 1. A heating element 17 is fixedly installed on the top of the muffle furnace body 1. The presence of the heating element 17 enables the heating function of the muffle furnace body 1. Specifically, the heating element 17 can be set as an insertable resistance wire, electric heating tube, etc., according to the actual experimental needs.

[0025] The front of the muffle furnace body 1 is hinged with an insulation door 2, and a handle 3 is fixedly connected to one side of the front of the insulation door 2. When the insulation door 2 is closed, it can form a sealing and heat insulation effect, thereby forming an independent heating space for the muffle furnace body 1.

[0026] When using a carbon black muffle furnace with safety protection features, the operator first spreads the carbon black evenly on the crucible and places the crucible inside the crucible placement slot 8. Then, the operator turns the handle 12, which moves the connecting block 14 via the screw 11, driving the scissor fork 15 to fold and retract the crucible into the muffle furnace body 1. After closing the insulation door, the carbon black is heated by the heating element 17. After heating and cooling, the insulation door 2 is opened, and the operator turns the handle 12 in the opposite direction, which moves the placement plate 7 and the movable block 9 along the slide 6 to move them out of the muffle furnace body 1. This method is convenient, saves time and effort, and prevents operators from taking materials from inside, thus avoiding burns. It makes the operation of the device safer and has a high level of safety protection. At the same time, it can maintain stability when moving the crucible containing carbon black along the slide 6, ensuring the stability of the crucible when it is moved out.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
