Description

Technical Field

[0001] The utility model relates to the technical field of waste heat utilization of cement production lines, and in particular to a fuel replacement drying system. Background Art

[0002] As the world's dependence on fossil fuels deepens, environmental and energy security issues are becoming increasingly prominent. This has prompted people to seek alternative fuel technologies to reduce dependence on traditional energy, reduce carbon emissions, and achieve sustainable energy development. Alternative fuel technology refers to the use of renewable or non-fossil energy as fuel to replace traditional fossil fuels. These technologies include biofuels, hydrogen energy, solar energy, wind energy, geothermal energy, etc., which are sustainable, environmentally friendly and renewable, and can reduce dependence on traditional energy and reduce carbon emissions. At the same time, it also helps to promote energy diversification and energy security. Among them, biofuels refer to fuels produced from biomass resources, such as biodiesel and bioethanol. The production and use of biofuels can reduce dependence on fossil fuels, reduce carbon emissions, and also help promote the development of agriculture and rural economy. The development of alternative fuel technology has been supported and promoted by governments around the world. Many countries have formulated relevant policies and regulations to encourage the research and development and application of alternative fuel technology. At the same time, international organizations and scientific research institutions are also promoting cooperation and exchanges in alternative fuel technology to accelerate its development and popularization. It can be seen that alternative fuel technology is one of the important directions for achieving sustainable energy development. With the advancement of technology and the promotion of its application, alternative fuel technology will provide more solutions to global energy and environmental problems.

[0003] In alternative fuel technology, materials eventually enter the combustion system to replace the calorific value of existing fuels, and the alternative fuels are generally waste materials. Alternative combustion not only saves the cost of the original fuel, but also processes the original waste materials. However, since the sources of waste materials are relatively complex and the moisture content is uncertain, it is difficult to ensure that the alternative fuel enters the combustion system in a dry state, resulting in poor stability of the combustion system and a significant impact on the calorific value of the fuel. Utility Model Content

[0004] The utility model aims to provide an alternative fuel drying system, which has high drying operation efficiency, good effect, strong system stability, and can greatly improve the calorific value of the processed fuel.

The materials are discharged from one side and evenly arranged on the mesh belt through the mixing mechanism. When the materials run to the turning mechanism, they are turned over and mixed with heat by the turning mechanism. After running through the mesh belt, they fall into the discharging mechanism and are transported out through the discharging mechanism.

[0044] A water washing mechanism 6 is provided at the bottom, and the water washing mechanism 6 is configured to spray water to clean the mesh belt.

[0045] Through the above technical solution, the mesh belt conveying mechanism of this system is used to convey materials. The mesh belt itself has ventilation holes (small aperture). The materials are discharged from one side and evenly arranged on the mesh belt through the mixing mechanism. When the materials run to the turning mechanism, they are turned over and mixed with heat by the turning mechanism. After running through the mesh belt, they fall into the discharging mechanism and are transported out through the discharging mechanism. While the above process is in progress, hot air is introduced from the top of the system and evenly distributed to the materials through the wind equalization device to dry the materials. After passing through the material layer, the hot air enters the suction mechanism through the mesh belt and discharges the air. While the above project is in progress, when the mesh belt turns to the wind washing part, the material mesh belt is cleaned by the action of wind sweeping, and the blown-off materials fall into the discharging mechanism. As the mesh belt runs to the water washing mechanism, the water washing mechanism can provide a reciprocating high-pressure water spraying device to clean the mesh belt to ensure the cleanliness of the mesh belt.

[0046] In this embodiment, in order to speed up the drying speed of the alternative fuel on the mesh belt, preferably, a plurality of vents are provided on the mesh belt, so that excess water on the alternative fuel can be quickly discharged through the vents, and the upper hot air can also pass through the vents to take away some of the water.

[0047] In actual use, since the system is tens of meters long and several meters wide, it can provide more materials.

In this embodiment, in order to solve the technical problem of the mesh belt deviating to the left or right, preferably, the alternative fuel drying system also includes a correction mechanism 7, which is used to correct the mesh belt that deviates to the left or right during operation.

[0048] like Figure 2 As shown, the above-mentioned correcting mechanism 7 can be any common structure in the art that can perform correcting direction. However, from the perspective of simplifying the structure and facilitating operation, preferably, the correcting mechanism includes an electric correcting device and a pressure sensor. The pressure sensor is connected to the electric correcting device and is configured to control the electric correcting device to perform real-time correction through a feedback signal.

[0049] When there is a requirement for the material layer height, in order to facilitate the adjustment of the height of the mixing mechanism 1 to control the material layer height, preferably, a spiral lifting mechanism 3 is provided at the bottom of the mixing mechanism 1 to adjust the height of the mixing mechanism 1 according to the height requirement.

Figure 7 ) and access door 12 (see Figure 4 ).

[0052] In addition, in order to further improve the drying speed of the alternative fuel on the mesh belt of the mesh belt conveyor mechanism 2 and avoid the accumulation of alternative fuel causing the moisture on its surface to concentrate to form a water pile and increase the difficulty of drying operation, preferably, a material distribution port is provided on the mixing mechanism 1 to evenly distribute the alternative fuel in the mixing mechanism 1 to the mesh belt of the mesh belt conveyor mechanism 2. By evenly distributing the alternative fuel on the mesh belt, the contact area between the moisture and the drying hot air can be increased, further accelerating the drying and optimizing the drying effect.

[0053] Also, see Figure 5 In order to improve the cleaning effect of the water washing mechanism 6 on the mesh belt in the alternative fuel drying system, preferably, the water washing mechanism 6 includes a reciprocating high-pressure water spraying device. In this way, the mesh belt can be efficiently cleaned by repeatedly spraying water with high pressure using the reciprocating high-pressure water spraying device.
