Description

Technical Field

[0001] This utility model relates to the field of box furnace technology, specifically to a box furnace column and a box furnace. Background Technology

[0002] The box furnace, also known as a muffle furnace, is simple to operate and easy to maintain, and is equipped with a controllable chimney at the rear. It is suitable for chemical analysis of coal, coking products, and chemical raw materials. It can be used in industries and sectors such as power generation, coal mining, papermaking, petrochemicals, cement, agriculture, animal husbandry, pharmaceutical research, and education.

[0003] Existing box-type furnaces heat materials using built-in heating elements. After heating, the heat must be expelled from the furnace body through an exhaust system before the furnace door can be opened for material removal. However, because the exhaust system consists of a set of exhaust holes and pipes, its exhaust rate is low, failing to quickly cool the furnace body. Furthermore, the poor cooling effect can easily cause burns to workers' hands, resulting in low safety and ineffective operation. Therefore, there is an urgent need for a box-type furnace column and a box-type furnace design to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a box furnace column and a box furnace, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a box-type furnace column and a box-type furnace, including a furnace body, with columns provided at the four corners of the furnace body, and a top cover fixed to the top of the furnace body and the top of the columns. An exhaust assembly is provided on the upper end of the top cover, and the exhaust assembly includes a fan installed above the top cover. A diversion valve is connected to the suction port of the fan, and four sets of guide pipes are distributed circumferentially on the outer wall of the diversion valve. An air guiding chamber is opened inside the column, and a vent plate is fixed on the outer wall of the column located in the furnace body section.

[0008] By adopting the above technical solution, the column can support the furnace body and ensure its stability during use. On the other hand, the air guide cavity and the air permeable plate inside it can serve as airflow channels. During the exhaust process, four sets of exhaust channels can be formed at the four corners of the furnace body. Under the action of the fan, the diversion valve and the guide pipe, the furnace body can be quickly cooled, ensuring its heat dissipation rate and effect. This facilitates the handling of materials by the staff and improves the safety factor and usage effect of the device.

[0009] Furthermore, the column located on the outer wall of the furnace body has an arc-shaped structure, and the column is welded to the four corners of the furnace body.

[0010] By adopting the above technical solution, the column can serve as a supporting component to support the entire device.

[0011] Furthermore, the top cover is welded to the top of the furnace body, and the blower is fixed to the top cover by a support frame.

[0012] By adopting the above technical solution, the top cover can seal the top of the furnace body, and the suction force generated by the fan can quickly expel the heat inside the furnace body, thereby cooling the interior and facilitating the handling of materials by the staff.

[0013] Furthermore, a connecting flange is provided on the exhaust port of the fan, and the diversion valve is a four-way valve, which is installed on the suction port of the fan through the flange.

[0014] By adopting the above technical solution, the diversion valve can divert the air force generated by the fan and distribute it to the four sets of columns through the guide pipe. The exhaust port of the fan can be connected to an external purification mechanism to purify the discharged gas.

[0015] Furthermore, one end of the guide pipe is threadedly connected to the diverter valve, and the other end of the guide pipe is fixedly connected to the column. The guide pipe is in communication with the air guide chamber, and a solenoid valve is also provided on the guide pipe.

[0016] By adopting the above technical solution, the guide tube can guide the gas flow, and the solenoid valve controls the opening and closing of the guide tube, which can be closed during the heating process to prevent heat loss.

[0017] Furthermore, a heat insulation layer is bonded inside the air guiding cavity, and the air permeable plate is fixed to the column by screws. The air permeable plate is in communication with the air guiding cavity, and the air permeable plate has an arc-shaped structure.

[0018] By adopting the above technical solution, the heat insulation layer can isolate heat, thereby preventing the outer wall temperature of the column from becoming too high.

[0019] Furthermore, a heating chamber is provided inside the furnace body, and a furnace door is installed on one side wall of the furnace body via a hinge, with a handwheel rotatably mounted on the furnace door.

[0020] By adopting the above technical solution, the furnace door can be opened to place the material into the heating chamber, and then the furnace door can be closed and fixed by the handwheel. Then the material is heated by the heating element built into the furnace body.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] This utility model features air guide chambers on four sets of columns and an exhaust mechanism consisting of a diversion valve, a guide pipe, and a permeable plate. During use, the columns support the furnace body, ensuring its stability. The air guide chambers and permeable plates inside the columns also serve as airflow channels. When exhaust is required after material heating, four exhaust channels are formed at the four corners of the furnace. Simultaneously, the fan, diversion valve, and guide pipe facilitate rapid heat dissipation within the furnace, ensuring efficient and effective heat dissipation. This also facilitates material handling by workers, improving the safety and effectiveness of the device. Attached Figure Description
