Technical Field
[0001] This utility model relates to the field of activation furnace technology, and in particular to a heat-insulating Sleip activation furnace. Background Technology
[0002] The Sleipner Activation Furnace is a heat treatment device widely used in activated carbon production, especially suitable for processes that prepare high specific surface area activated carbon from coal-based or wood-based raw materials. Its core design is based on the moving bed gas-solid countercurrent contact principle, achieving integrated carbonization and activation of raw materials by controlling parameters such as temperature, airflow, and residence time. It features high efficiency, energy saving, and stable product performance.
[0003] During use, a large amount of impurities will accumulate inside the activation furnace. In order to extend the service life of the activation furnace, it is necessary to clean and maintain the inside of the furnace regularly. During the use of the activation furnace, the furnace body is heated at high temperature, and the furnace body is equipped with a heat preservation device. Therefore, when cleaning and maintaining the inside of the activation furnace, it is necessary to dissipate heat first. However, the heat preservation device on the furnace body will seriously affect the heat dissipation of the activation furnace, resulting in a reduction in the working efficiency of the activation furnace.
[0004] Therefore, a Sleip activation furnace is needed that can keep the furnace body warm and dissipate heat according to usage requirements. Utility Model Content
[0005] This invention addresses the shortcomings of existing technologies by providing a heat-insulating Sleip activation furnace that allows gas to be introduced or discharged into the vacuum chamber through vents, thereby increasing the furnace's heat preservation or heat dissipation effect according to usage requirements. It is simple, efficient, safe, reliable, and easy to operate.

[0007] As an optimization, the reflective layer A and the insulation layer A are located outside the heat insulation layer A; the heat insulation layer A isolates the heat inside the furnace body, preventing the reflective layer A and the insulation layer A from being damaged due to excessive temperature.
[0008] As an optimization, an insulation board is provided on the outside of the furnace body, with reflective layer A and insulation layer A located on the insulation board; the reflective layer A and insulation layer A are mounted and dismounted on the furnace body through the insulation board, thereby facilitating the increase of the furnace body's insulation or heat dissipation effect according to usage requirements.
[0009] As an optimization, the furnace body is equipped with a sealing cover, which has a heat insulation layer B, a reflective layer B, and a heat preservation layer B arranged sequentially from the inside to the outside. The furnace body can be opened or closed by the sealing cover, so as to facilitate the increase of the heat preservation or heat dissipation effect of the furnace body according to the usage requirements.
[0010] The beneficial effects of this utility model are as follows: the vent hole allows gas to be introduced or discharged into the vacuum chamber, thereby increasing the heat preservation or heat dissipation effect of the furnace body according to the usage requirements; the reflective layer A and the heat preservation layer A are mounted and dismounted on the furnace body through the heat preservation plate, thereby facilitating the increase of the heat preservation or heat dissipation effect of the furnace body according to the usage requirements.

[0014] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0015] like Figure 1 The heat-insulating Sleip activation furnace of this utility model includes a furnace body 1, and a heating device 2 is provided inside the furnace body 1. The furnace body 1 is provided with a heat insulation layer A3, a reflective layer A4, and a heat insulation layer A5. The heat insulation layer A3 includes a vacuum chamber located inside the wall of the furnace body 1. The furnace body 1 has a vent 6 that communicates with the vacuum chamber. The heating device 2 is existing technology. The heat insulation layer A3, the reflective layer A4, and the heat insulation layer A5 enclose the inner cavity of the furnace body 1. The reflective layer A4 can be made of materials that reflect infrared radiation, such as aluminum foil. The heat insulation layer A5 can be made of materials with low thermal conductivity, such as foam or rock wool, or heat insulation materials with a loose structure, such as fur or cotton. The vacuum chamber can be connected to a vacuum pump, a fan, or a water pump through the vent 6. The vacuum pump removes air from the vacuum chamber. Several vent 6 that communicate with the vacuum chamber can be opened on the furnace body 1. The fan or water pump makes the fluid in the vacuum chamber flow, accelerating the heat dissipation effect of the furnace body 1. A sealing valve 12 is provided on the vent 6.
[0016] Air is drawn out of the vacuum chamber through the vent 6 until the vacuum chamber is in a vacuum state; the raw material is placed into the furnace body 1, and the heating device 2 is started. The heating device 2 heats the raw material in the furnace body 1. The heat insulation layer A3, the reflective layer A4 and the heat preservation layer A5 sequentially isolate the heat in the furnace body 1 to prevent heat loss and keep the interior of the furnace body 1 warm.
[0017] When the inner cavity of the furnace body 1 needs to be cleaned and repaired, the heating device 2 is turned off, and fluid is input and output into the vacuum chamber through the vent 6. The fluid carries away some of the heat inside the furnace body 1, and at the same time, the fluid medium eliminates the effect of vacuum insulation, accelerating the loss of heat inside the furnace body 1.
[0018] like Figure 1 The reflective layer A4 and the heat insulation layer A5 shown are located outside the heat insulation layer A3; the heat insulation layer A3, the reflective layer A4 and the heat insulation layer A5 are arranged sequentially from the inside to the outside on the furnace body 1.
[0019] like Figure 1 The furnace body 1 shown is provided with an insulation board 7 on the outside, and the reflective layer A4 and the insulation layer A5 are located on the insulation board 7. The insulation board 7 is arranged around the furnace body 1 and is hinged to the furnace body 1, or is set on the furnace body 1 by means of buckles or other means.
[0020] The insulation board 7 is installed on the outside of the furnace body 1, and the reflective layer A4 and the insulation layer A5 wrap the furnace body 1. The raw materials are put into the furnace body 1, and the heating device 2 is started. The heating device 2 heats the raw materials in the furnace body 1. The heat insulation layer A3, the reflective layer A4 and the insulation layer A5 sequentially isolate the heat in the furnace body 1, prevent the heat in the furnace body 1 from being lost and keep the inside of the furnace body 1 warm.
[0021] When the inner cavity of the furnace body 1 needs to be cleaned and repaired, turn off the heating device 2, remove the insulation board 7 from the furnace body 1, and the reflective layer A4 and the insulation layer A5 detach from the furnace body 1. The heat inside the furnace body 1 passes through the heat insulation layer A3 and is lost at an accelerated rate.
[0022] like Figure 1 The furnace body 1 shown is equipped with a sealing cover 8, on which a heat insulation layer B9, a reflective layer B10, and a heat preservation layer B11 are arranged sequentially from the inside to the outside. The furnace body 1 is equipped with a feed inlet, and the sealing cover 8 is located at the feed inlet. The bottom of the furnace body 1 is equipped with a reflective layer C13 and a heat preservation layer C14. The heat insulation layer B9 is a vacuum chamber located inside the sealing cover 8. The reflective layers A4, B10, and C13 are made of the same material, and the heat preservation layers A5, B11, and C14 are made of the same material.
[0023] Place the raw materials into the furnace body 1, close the sealing cover 8, and start the heating device 2. The heating device 2 heats the raw materials in the furnace body 1. The heat insulation layer B9, the reflective layer B10, and the heat preservation layer B11 sequentially isolate the heat in the furnace body 1, prevent the heat from being lost from the furnace body 1, and keep the interior of the furnace body 1 warm.
[0024] When the sealing cover 8 is opened, the heat insulation layer B9, the reflective layer B10, and the heat preservation layer B11 detach from the furnace body 1, resulting in the loss of heat from the furnace body 1.
[0025] In actual production, air is drawn out of the vacuum chamber through the vent 6 until the vacuum chamber is in a vacuum state; the insulation board 7 is installed on the outside of the furnace body 1, and the reflective layer A4 and the insulation layer A5 wrap the furnace body 1; the raw material is put into the furnace body 1 and the sealing cover 8 is closed, the heating device 2 is started, and the heating device 2 heats the raw material in the furnace body 1. The heat insulation layer A3, the reflective layer A4 and the insulation layer A5 sequentially insulate the heat in the furnace body 1, and the heat insulation layer B9, the reflective layer B10 and the insulation layer B11 sequentially insulate the heat in the furnace body 1, so as to prevent the heat in the furnace body 1 from being lost and to keep the inside of the furnace body 1 warm.
[0026] When cleaning and maintenance of the inner cavity of furnace body 1 is required, turn off the heating device 2 and input and output fluid into the vacuum chamber through the vent 6. The fluid carries away some of the heat inside furnace body 1 and eliminates the vacuum insulation effect through the fluid medium, accelerating the loss of heat inside furnace body 1. Remove the insulation plate 7 from furnace body 1, and the reflective layer A4 and insulation layer A5 detach from furnace body 1. The heat inside furnace body 1 passes through the insulation layer A3 and is lost more quickly. Open the sealing cover 8, and the insulation layer B9, reflective layer B10 and insulation layer B11 detach from furnace body 1, allowing the heat inside furnace body 1 to be lost.
