Description

Technical Field

[0001] This utility model belongs to the field of flame-retardant paper production technology, specifically relating to a flame-retardant paper drying equipment. Background Technology

[0002] Flame-retardant paper refers to a general term for a type of paper that has non-combustible or flame-retardant properties. Flame-retardant paper has high strength and appearance properties as well as excellent flame-retardant properties. Flame-retardant paper is generally divided into two categories. One type refers to paper made from asbestos fibers that does not undergo any changes in fire. This type of paper is also often called fireproof paper. The other type refers to paper in which flame-retardant chemicals are added to the pulp or plant fibers are treated with flame retardants to obtain flame-retardant properties. Although this type of flame-retardant paper does not burn or produce open flames, it will char and turn black and charred when exposed to fire.

[0003] In existing technologies, flame-retardant paper is mainly used in fire-prevention applications. The production process involves impregnating the base paper with a flame retardant. This impregnation requires the base paper to be dried before the flame-retardant paper can be obtained. Natural air drying is time-consuming and space-consuming, which is inconvenient. Existing drying equipment can only stack the flame-retardant paper during the drying process, resulting in slow drying in the center and poor drying effect, wasting time and energy. Therefore, we propose a flame-retardant paper drying device. Utility Model Content

[0004] The purpose of this invention is to provide a flame-retardant paper drying device to solve the technical problems of low drying efficiency and poor drying effect, and to achieve high drying efficiency and good drying effect.

[0005] To solve the above-mentioned technical problems, this utility model provides a flame-retardant paper drying device, including a drying box. A control panel is provided on the front of the drying box. A drying chamber is opened inside the drying box near the front. Several sets of slide rails are symmetrically arranged on the left and right sides of the drying chamber. A drying screen is installed inside each slide rail. Two first ventilation screens are provided on the back of the drying screen. A heater is provided on the back of each first ventilation screen. A fan blade is provided on the back of each heater. A drive motor is provided on the back of each fan blade. An electrically controlled door is arranged opposite each other above the drying screen. A temperature sensor is arranged at the bottom of the electrically controlled door near the back. A second ventilation screen is arranged above the electrically controlled door.

[0006] Furthermore, the slide rail is bolted to the drying box, and the drying mesh is slidably connected to the slide rail.

[0007] The above technical solution, which uses a slide rail and a drying chamber to be fixed with bolts, and a drying screen to be slidably connected to the slide rail, allows the drying screen to be easily pulled out of the drying chamber, making it convenient to place the raw paper on the drying screen, keep it flat, and facilitate its drying process.

[0008] Furthermore, the heater is fixedly connected to the drying chamber, and the heater is centrally controlled by a control panel.

[0009] With the above technical solution, the heater is fixedly connected to the drying oven, and the heater is centrally controlled by the control panel. The temperature can be effectively controlled through the control panel, thereby improving the heating effect.

[0010] Furthermore, the fan blades are bolted to the output end of the drive motor, and the drive motor is centrally controlled by the control panel.

[0011] The above technical solution uses bolts to fix the fan blades to the output end of the drive motor. The drive motor is centrally controlled by the control panel. It can effectively drive the fan blades to blow air into the interior, so that the heat generated by the heater can heat the air to dry the paper.

[0012] Furthermore, the fixed end of the electrically controlled door is bolted to the drying oven, and the electrically controlled door is centrally controlled by the control panel.

[0013] The above technical solution uses bolts to fix the fixed end of the electric control door to the drying chamber. The electric control door is centrally controlled by the control panel, which can effectively raise the temperature inside the drying chamber and promptly discharge waste heat air when needed.

[0014] Furthermore, the temperature sensor is bolted to the fixed end of the electric control door, and the temperature sensor is centrally controlled by a control panel.

[0015] The above technical solution uses a temperature sensor fixed to the fixed end of the electric control door with bolts. The temperature sensor is centrally controlled by the control panel, which can effectively detect the temperature inside the drying room, thus facilitating internal temperature control.

[0016] Furthermore, the first ventilation mesh is bolted to the drying box, and the second ventilation mesh is bolted to the drying box.

[0017] The above technical solution, which uses bolts to fix the first ventilation mesh to the drying box and the second ventilation mesh to the drying box, effectively ensures air circulation and facilitates the drying process.

[0018] The beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting up several sets of slide rails and drying nets, the slide rails can facilitate the sliding of the drying nets in the drying chamber, so that the drying nets can be easily removed before drying the raw paper, allowing the raw paper to be placed flat on them. This makes the dried flame-retardant paper flatter and the drying effect better. By setting up multiple sets of slide rails and drying nets, the flame-retardant paper can be dried separately to ensure the drying effect and prevent the situation where the outside is over-dried while the inside remains moist.

[0020] 2. In this utility model, the temperature sensor can effectively detect the temperature inside the drying chamber, and the heater can be adjusted through the control panel to maintain a suitable temperature inside, thereby achieving the best drying effect on the flame-retardant paper. The drive motor can effectively drive the fan blades to heat the air with the heater, thereby achieving the drying effect. The electric control door facilitates the replacement of waste heat air.
