Description

Technical Field

[0001] This utility model relates to the field of impregnation furnace technology, specifically to an impregnation furnace with rapid cooling and exhaust. Background Technology

[0002] An impregnation furnace is a device used to impregnate solid materials with liquid substances. It is widely used in materials science, metallurgy, chemical engineering and other fields. The principle of vacuum pressure impregnation is to first evacuate the furnace to a vacuum state to remove air and other gases from the pores of the solid material. Then, under pressure, the liquid impregnating agent fills the pores and gaps of the solid material to achieve the purpose of impregnation. For example, in the production of metal-impregnated carbon slide plates, the vacuum pressure impregnation method allows the molten metal and alloy to penetrate the porous carbon blank better. The principle of hot impregnation is to use heating to expand the solid material, increase the pore size, and at the same time reduce the viscosity of the liquid impregnating agent, making it easier for it to penetrate into the interior of the solid material. For example, in the wood impregnation process, heating the wood and the impregnating agent improves the impregnation effect.

[0003] Existing impregnation furnaces, such as the resin impregnation and curing furnace with rapid cooling and exhaust disclosed in publication number "CN213891352U", use "nitrogen pipes distributed in a ring shape at the bottom of the furnace liner...the material is cooled evenly in all parts, the cooling efficiency is high and the speed is fast". However, in actual operation, nitrogen only enters from the bottom, which means that the cooling of the inner liner needs to be carried out slowly from the bottom, reducing its practicality. Utility Model Content

[0004] The purpose of this invention is to provide a rapid cooling and exhaust impregnation furnace to solve the problem mentioned in the background art, where nitrogen gas only enters from the bottom during actual operation, resulting in the need for slow cooling of the inner liner from the bottom, which reduces its practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling and exhaust impregnation furnace, comprising an outer shell with an internal cavity, and a processing inner liner fixed within the cavity of the outer shell. A bottom support is fixed to the bottom surface of the cavity of the outer shell, and a bottom air outlet is fixedly connected to the upper surface of the bottom support. Two upper supports are fixedly connected to the inner wall of the cavity of the outer shell, and upper air outlets are fixedly connected to the surfaces of the upper supports. A drainage pipe is installed through the lower side surface of the outer shell. A drive motor is fixedly connected to the upper side surface of the outer shell. A transmission gear is provided on the inner wall of the outer shell. A linkage turntable is installed on the inner wall of the outer shell. A first tooth block is fixedly connected to the lower surface of the linkage turntable. A limit baffle is fixed between the outer shell and the processing inner liner. A linkage exhaust mechanism is provided between the outer shell and the limit baffle. The linkage turntable and the first tooth block drive the transmission gear and the air guide baffle to rotate, while the linkage turntable drives the auxiliary gear and the exhaust baffle to rotate through the second tooth block, facilitating the exhaust of gas from the exhaust fan.

[0009] By adopting the above technical solution, the upper bracket is designed in a ring shape and the air inlet end penetrates through the surface of the mounting shell. Gas can be introduced from the top of the processing inner liner. In conjunction with the air inlet of the bottom bracket, air can be supplied to the processing inner liner from both the top and bottom at the same time. This makes the temperature distribution inside the processing inner liner more uniform and the cooling more rapid and comprehensive. It effectively solves the problem of slow cooling caused by only introducing air from the bottom in the existing technology.

[0012] Preferably, the linkage exhaust mechanism includes an air guide baffle, which is embedded in the inner wall of the opening on the surface of the limiting baffle. A second tooth block is fixedly connected to the upper side surface of the linkage turntable. An auxiliary gear is provided on the side of the second tooth block. An exhaust baffle is fixedly connected to the upper end of the rotating shaft of the auxiliary gear. An exhaust fan is fixedly connected to the upper side surface of the mounting housing.

[0013] Using the above technical solution, the air guide baffle is embedded in the inner wall of the opening on the surface of the limiting baffle. It rotates under the drive of the linkage turntable, which can guide the gas in the processing liner to a specific direction, so that it can be discharged in an orderly manner through the exhaust fan, thereby improving the exhaust efficiency and avoiding the disorderly flow of gas in the equipment, which would affect the impregnation and cooling effect.

[0014] Preferably, the air guide baffle and the limiting baffle are rotatably connected, and the limiting baffle is annularly designed. The auxiliary gear is meshed with the second tooth block, and the auxiliary gear is rotatably connected with the mounting housing.

[0015] The above technical solution is adopted, in which the gas guide baffle and the limiting baffle are rotatably connected, so that the gas guide baffle can rotate flexibly and adjust the gas guiding direction according to the rotation angle of the linkage turntable, so as to adapt to different working conditions and gas flow requirements, and further optimize the gas flow path in the equipment.

[0016] Preferably, the exhaust baffle is rotatably connected to the exhaust slot of the mounting housing, and the exhaust baffle is correspondingly arranged with the exhaust fan.

[0017] By adopting the above technical solution, the exhaust baffle is rotatably connected to the exhaust groove of the mounting shell, which can precisely control the opening and closing of the exhaust channel.
