Description

Technical Field

[0001] The present invention relates to the technical field of biomass wave-absorbing material preparation, and in particular to a device for preparing biomass wave-absorbing material. Background Art

[0002] The preparation of biomass absorbing materials is a process that uses natural biological resources to produce materials with electromagnetic wave absorption capabilities. This material is widely used in military, communications, electronics and other fields. It has the characteristics of environmental protection, renewable nature and excellent performance. The raw materials of biomass absorbing materials are usually made from natural biological macromolecules (such as cellulose, hemicellulose and lignin) and other natural resources (such as bamboo, coconut shells, straw, etc.). The raw materials need to be crushed and pre-treated to facilitate subsequent operations, and then processed through drying equipment and carbonization equipment.

[0003] In the existing technology, the preparation of biomass absorbing materials mainly relies on traditional drying and carbonization processes. These processes usually adopt a step-by-step, open processing method, that is, drying first and then carbonization. However, this method has multiple problems: First, uneven drying of the raw materials will lead to insufficient heating. The raw materials are easy to carbonize in a relatively dry state, but in a humid state, the raw materials need to go through a process from wet to dry. Carbonization cannot be achieved before the water vapor evaporates, so there is a problem of uneven carbonization caused by uneven drying. Secondly, open processing is easily affected by environmental factors, such as moisture and impurities in the air, which affects the quality of the final product; the common problems and shortcomings of the existing technology mainly include: the separation of drying and carbonization processes, resulting in low energy utilization efficiency; uneven raw material processing, affecting the quality and performance of the final product; open processing is susceptible to environmental pollution, reducing product purity; there are certain defects, so it is necessary to develop a biomass absorbing material preparation device.

A detection unit for detecting the status of the raw materials is provided in the arc-shaped cover;

[0010] The input end of the pressure air pump is connected to the air cavity of the dynamic collection plate through the second air duct. A drying box is also provided on the second air duct. The input end of the feed air pump is connected to the drying box through the second air duct. The feed air pump can circulate and swirl the raw materials. At the same time, the pressure air pump can form an internal air circulation between the heating disc and the dynamic collection plate.

[0011] The heated airflow output by the heating disc can make the raw materials in the heating carbonization chamber in an air-floating state, and separate the raw materials into upper and lower layers of dry and wet, with the upper part being light and the lower part being heavy. At the same time, the swirl output by the annular feeding pipe can separate the raw materials into inner and outer layers of dry and wet, with the outer part being heavy and the inner part being light. The dry raw materials in the heating carbonization chamber are located at the upper center of the swirl, while the wet raw materials are located at the edge and bottom of the swirl, so that the heated airflow can carbonize the dry raw materials while drying the wet raw materials at the same time.

[0012] When the dynamic collecting plate moves and the arc cover enters the upper part of the cyclone center, the raw materials in the floating state and carbonized will enter the arc cover.

Air duct 2 extends out of the preparation cylinder and is connected to the drying box. At the same time, the second section of the air duct located on the top of the dynamic collection tray is a folded hose structure, which cooperates with the lifting and lowering of the dynamic collection tray. The output end of the feed air pump is connected to the closed silo through air duct 1, and the input end of the feed air pump is connected to the drying box through air duct 2.

[0017] Furthermore, a material port is provided on the top of the silo, which can be opened for feeding and closed for sealing.

[0018] Furthermore, a guide end is provided at the top of the discharge pipe to assist the raw materials in entering.

[0019] Furthermore, the heating element is a heating coil or a heating ring.

[0020] Furthermore, it also includes an adaptive protection component arranged in the heating disc to protect the heating cavity and prevent raw materials from falling into the heating cavity.

[0021] The beneficial effects of the present invention are as follows: the present invention has a unique structure and an ingenious design.

By providing a humidity sensor and a carbonization sensor connected to the controller, the drying and carbonization states of the raw materials are monitored in real time, and the judgment and processing of the drying and carbonization states of the raw materials are achieved. The controller can accurately control the lifting and lowering of the dynamic collection plate according to the sensor signals, realize automated operation to collect raw materials, and improve production efficiency and product quality. At the same time, the closed oxygen-free environment is not only used in the preparation process, but also extends to the finished product storage stage, preventing the carbonized porous structure material from absorbing moisture and dust in the air, thereby maintaining its excellent wave absorbing and energy dissipation effect.

[0022] Through the designed dual circulation mechanism of raw material circulation feeding and heated carbonization air circulation, the heated airflow can realize the carbonization of dry raw materials and the drying of wet raw materials, thereby improving energy utilization efficiency. The combined effect of heated airflow and centrifugal force can realize multi-level separation of raw materials. The heated airflow is used to realize the upper and lower dry and wet stratification of raw materials, while the centrifugal force is used to realize the dry and wet internal and external stratification of raw materials, forming a distribution in which dry raw materials are located in the upper part of the cyclone center and wet raw materials are located at the edge and bottom of the cyclone, ensuring that raw materials with different humidity are treated accordingly. The moisture content in the airflow is reduced by the drying box, and the circulating airflow is continuously dried to ensure that the circulating airflow is in the best dry state.

[0023] The lifting control component can control the lifting of the dynamic collection tray.

DETAILED DESCRIPTION

[0035] The present invention will be further described below with reference to the accompanying drawings and examples.

[0036] Example 1. The preparation of biomass absorbing materials mainly relies on traditional drying and carbonization processes. These processes usually adopt a step-by-step, open processing method, that is, drying first and then carbonization. However, this method has multiple problems: First, uneven drying of the raw materials will lead to insufficient heating. The raw materials are easy to carbonize in a relatively dry state, but in a humid state, the raw materials need to go through a process from wet to dry. Carbonization cannot be achieved before the water vapor evaporates, so there is a problem of uneven carbonization caused by uneven drying. Secondly, open processing is easily affected by environmental factors, such as moisture and impurities in the air, which affect the quality of the final product; the common problems and shortcomings of the existing technology mainly include: the separation of drying and carbonization processes, resulting in low energy utilization efficiency; uneven raw material processing, affecting the quality and performance of the final product; open processing is susceptible to environmental pollution, reducing product purity.

[0037] In response to the above problems, this embodiment provides a biomass absorbing material preparation device, which improves the drying and carbonization efficiency of biomass raw materials through flow circulation and dynamic collection mechanisms, and realizes the production of high-quality absorbing materials. Figure 1-3 As shown, a fixed partition, a dynamic collection tray 7, and a heating disc 2 are sequentially arranged in the preparation cylinder 1 from top to bottom. The fixed partition and the heating disc 2 are fixedly installed. A closed material bin 102 is located above the fixed partition, and a sealed storage bin 103 is located below the heating disc 2. The dynamic collection tray 7 is slidably mounted in the preparation cylinder 1. A lifting control assembly for controlling the lifting of the dynamic collection tray 7 is provided on the fixed partition, and a heating carbonization chamber 104 is formed between the heating disc 2 and the dynamic collection tray 7.

[0038] A heating element is provided in the heating chamber 21 of the heating disc 2. The heating element can be a heating coil 22 or a heating ring, which can heat the oxygen-free gas. A plurality of conical air nozzles 4 are evenly distributed on the top of the heating disc 2. The output end of the external pressure air pump 3 is connected to the heating chamber 21 via an air duct 91. The pressure air pump 3 delivers positive-pressure oxygen-free gas into the heating chamber 21. The heating coil 22 heats the oxygen-free gas to 400-600 degrees Celsius. The heated positive-pressure oxygen-free gas is discharged through the conical air nozzles 4 to form a heated airflow. The heated airflow is used to carbonize dry raw materials and dry moist raw materials.

[0039] The heated air flow output by the heating fan can make the raw materials with the same particle size float in a state, so as to realize the dry and wet stratification of the raw materials. The upper layer is relatively dry raw materials, and the lower layer is relatively moist raw materials. The moist raw materials will be relatively heavy, and the partially dry raw materials will be relatively light, that is, the light and heavy layers are formed, with the upper layer being light and the lower layer being heavy.

[0040] The edge of the heating air disc is provided with an annular groove 23, in which an annular feed pipe 5 is fixedly sleeved, and the annular feed pipe 5 is provided with a plurality of upwardly inclined rotary discharge ports 6 in sequence along the radial direction;

[0041] The output end of the feeding air pump 9 is connected to the closed silo 102 through the air pipe 131. The closed silo 102 is provided with a feeding port 101, which can be opened for feeding and is sealed. A conical guide body 8 is provided on the top of the fixed partition. A material trough 801 is provided on the side of the conical guide body 8. The raw materials in the closed silo 102 will be guided by the conical guide body 8 to multiple material troughs 801 around it. The material troughs 801 are connected to the annular feeding pipe 5 through the feeding pipe 10 outside the preparation cylinder 1. The feeding air pump 9 delivers positive air pressure to the closed silo 102, which can blow the raw materials in the material trough 801 into the annular feeding pipe 5 through the feeding pipe 10 and discharge them through the rotary discharge port 6 of the annular feeding pipe 5.

[0042] The feed air pump 9 provides feed air pressure, which can make the airflow discharged from the annular feed pipe 5 form a swirl through the swirl outlet 6, so that the feed of raw materials forms a rotating feed, so that the raw materials can rotate and flow along the cylinder wall;

[0043] When the raw materials are fed in a rotating manner, the centrifugal force causes the heavy wet raw materials to be located on the outer layer, while the light dry raw materials are pressed to the inner layer.

[0044] Under the action of gravity, the heated airflow makes the raw materials light on the top and heavy on the bottom, forming dry and wet layers. Then, centrifugal force separates the raw materials into dry and wet layers, making them heavy on the outside and light on the inside. As a result, the dry raw materials in the heated carbonization chamber 104 are located at the upper center of the cyclone, while the wet raw materials are located at the edge and bottom of the cyclone.

[0045] The lifting control assembly includes a drive motor 12 provided on the fixed partition 105. The drive motor 12 is enclosed and located inside the conical guide body 8. A screw 13 is connected to the output shaft of the drive motor 12. The dynamic collection tray 7 is sleeved on the screw 13. A guide post 14 is vertically provided between the fixed partition and the dynamic collection tray 7. The dynamic collection tray 7 is guided on the guide post 14. The drive motor 12 drives the screw 13 to control the lifting and lowering of the dynamic collection tray 7.

[0046] An air cavity 71 is provided inside the dynamic collecting tray 7. A second air duct 92 is installed on the top of the dynamic collecting tray 7. The air duct extends out of the preparation cylinder 1 and is connected to the input end of the supply pressure air pump 3. The input end of the supply pressure air pump 3 is connected to the air cavity 71 of the dynamic collecting tray 7 through the second air duct 92. The output end of the supply pressure air pump 3 is connected to the heating chamber 21 of the heating air tray through the first air duct 91 to deliver positive pressure oxygen-free gas. The input end of the supply pressure air pump 3 is connected to the internal air cavity 71 of the dynamic collecting tray 7 through the second air duct 92, so that the dynamic collecting tray 7 can suck the oxygen-free gas at a negative pressure. An internal oxygen-free gas airflow circulation is formed between the heating disc 2 and the dynamic collecting tray 7.

[0047] The second air duct 92 section on the top of the dynamic collecting tray 7 is a folded hose structure, and a drying box 15 is installed on the second air duct 92 extending from the preparation cylinder 1 to dry the oxygen-free gas. When the air circulates inside the preparation cylinder 1, the air flow will contain humid gas, so the humid gas is absorbed by the drying box 15 to dry the air flow, and the desiccant in the drying box 15 is replaced regularly; at the same time, the input end of the feed air pump 9 is connected to the drying box 15 through the second air pipe 32, and the feed air pump 9 can circulate and swirl the raw materials. At the same time, the pressure air pump 3 can form an internal air circulation between the heating disc 2 and the dynamic collecting tray 7, realizing a double circulation of the air flow in the preparation cylinder 1;

[0048] A filter screen 72 is installed at the bottom of the air cavity 71 of the dynamic collecting tray 7, and an arc-shaped cover 73 is installed at the bottom of the dynamic collecting tray 7. Air inlet holes 74 are evenly distributed on the arc-shaped cover 73. The arc-shaped structure of the arc-shaped cover 73 can cooperate with the upper part of the swirl center, and a discharge pipe 11 is fixedly connected to the central bottom of the arc-shaped cover 73. The discharge pipe 11 is sealingly and slidably sleeved on the heating disc 2, and its end extends into the sealed storage bin 103. The filter screen 72 can filter and block the carbonized raw materials entering the arc-shaped cover 73, allowing only oxygen-free gas to enter the air cavity 71. The filtered and blocked raw materials will fall onto the arc-shaped cover 73 and be guided by the arc-shaped cover 73 to the discharge pipe 11 at the center thereof, and then discharged into the sealed storage bin 103.

[0049] The raw materials that have been carbonized in the upper part of the cyclone are not directly sucked into the arc cover 73 by the negative pressure. Only when the arc cover 73 moves down and falls to the upper part of the cyclone, the raw materials that are in the air-floating state and have been carbonized will automatically enter the arc cover 73. At this time, the raw materials in the arc cover 73 will be sucked by the negative pressure. The raw materials are blocked by the filter 72, and the raw materials accumulate on the filter 72. The flow rate of the raw materials slows down and they will fall into the arc cover 73. This is the existing gas-solid separation principle.

[0050] A detection unit for detecting the drying and carbonization status of the raw materials is provided in the arc cover 73. The detection unit includes a humidity sensor and a carbonization sensor in the prior art. The humidity sensor and the carbonization sensor are connected to the controller signal. The humidity sensor detects the dryness of the raw materials, and the carbonization sensor detects the carbonization degree of the raw materials. The carbonization sensor detects the carbon content of the raw materials. After the raw materials are carbonized, their chemical properties change, and the carbonization degree of the raw materials can be detected.

[0051] When the drying sensor and the carbonization sensor detect that the carbonization of the raw materials is qualified, the lifting control component controls the dynamic collecting tray 7 to move downward, and the arc cover 73 enters the upper middle part of the vortex in the heating carbonization chamber 104. The carbonized raw materials enter the arc cover 73 through the air inlet hole 74. The dynamic collecting tray 7 can suck the oxygen-free gas under negative pressure, and the airflow synchronously drives the carbonized raw materials. Then the raw materials are blocked by the filter screen 72, and the filtered raw materials are guided by the arc cover 73 to the discharge pipe 11 and discharged to the sealed storage bin 103.

[0052] When the drying sensor and the carbonization sensor detect that the raw materials have not been completely carbonized, the lifting control assembly controls the dynamic collection tray 7 to move upward, so that the arc cover 73 is away from the upper middle part of the vortex in the heating carbonization chamber 104. The dynamic collection tray 7 only sucks in the oxygen-free gas under negative pressure and does not suck in the raw materials in the floating state.

[0053] This feature is that when the dynamic collecting tray 7 is away from the middle and upper part of the vortex in the heating carbonization chamber 104, the air flow circulation always exists, and only the internal air flow circulation is performed, and the raw materials are not sucked by the negative pressure. The raw materials are in an air floating state and will not be sucked and moved by the negative pressure; when the dynamic collecting tray 7 moves downward and the arc cover 73 enters the middle and upper part of the vortex in the heating carbonization chamber 104, the carbonized raw materials will enter the arc cover 73 through the air inlet hole 74, and the raw materials will be sucked and moved by the negative pressure.

[0054] The controller controls the lifting timing of the dynamic collection tray 7 according to the detection result signals of the drying sensor and the carbonization sensor. When it is detected that the raw materials in the upper part of the vortex are dried and carbonized, the dynamic collection tray 7 is allowed to move down for collection. When it is detected that the raw materials in the upper part of the vortex are not dried and carbonized, the dynamic collection tray 7 is allowed to move up and away, so that the raw materials continue to be dried and carbonized. The above process is repeated, so that the dynamic collection tray 7 has a dynamic collection effect.

[0055] The raw materials in the upper part of the cyclone are relatively dry and easy to carbonize. The raw materials at the edge and bottom of the cyclone are relatively wet, so they need to be dried. After drying, they will move to the upper part of the cyclone to be carbonized. The raw materials are fed by the feed air pump 9 in a cyclone. The heated air flow evaporates the moisture in the wet raw materials at the edge and bottom of the cyclone, and the heated air flow carbonizes the dry raw materials in the upper part of the cyclone.

[0056] When the raw materials are in the flotation cyclone state, their drying and carbonization are carried out simultaneously. The dried raw materials are carbonized by the heated airflow, and the moist raw materials are dried by the heated airflow. This solution has a dual circulation mechanism in an anaerobic state, including the circulating feeding of raw materials and the circulation of heated carbonization airflow, and the carbonization preparation of raw materials in the preparation cylinder 1 is in a fully enclosed, sealed and anaerobic state, which can prevent the raw materials from absorbing moisture in the air and also prevent the raw materials from absorbing dust. The raw material particles after carbonization have a porous structure, which avoids the raw materials from contacting with the air and adsorbing free dust in the air, affecting the material's wave absorption and energy dissipation effect.

[0057] Based on the above-mentioned solution of the biomass absorbing material preparation device, the specific implementation steps when using it are as follows: the feed port 101 of the closed silo 102 is opened, the crushed biomass raw material is placed in the closed silo, and the feed port 101 is closed to ensure that the feed port 101 is sealed, maintaining the oxygen-free environment of the system, ensuring the sealing of the preparation cylinder 1 to prevent moisture and pollutants from the outside air from entering, starting the pressure supply air pump 3 to deliver positive pressure oxygen-free gas to the heating chamber 21 through the air duct 91, and starting the heating coil 22 to heat the oxygen-free gas to 400-600 degrees Celsius, creating a heating environment and providing the necessary conditions for drying and carbonizing the raw materials;

[0058] Start the feeding air pump 9 to send positive pressure gas into the closed silo 102 through the air pipe 31. The air flow pushes the raw materials through the feeding pipe 10 to the annular feeding pipe 5, and forms a vortex through the vortex discharge port 6. The raw materials form a rotating feed with the help of the vortex discharge port 6, and rotate along the cylinder wall to achieve uniform distribution of the raw materials. The dry raw materials are placed in the upper layer and the wet raw materials are placed in the lower layer by using centrifugal force and gravity. In other words, the dry and wet raw materials are separated into upper and lower layers and inside and outside layers by the combination of gravity and centrifugal force. At the same time, the heated air flow is discharged through the conical air nozzle 4, and the temperature is increased, thereby achieving carbonization of the dry raw materials in the upper layer and drying of the wet raw materials in the lower layer. The heat of the air flow is used to achieve simultaneous drying and carbonization of the raw materials, thereby improving processing efficiency.

[0059] The drying and carbonization conditions of the raw materials are monitored in real time by humidity sensors and carbonization sensors. The controller determines the timing of raising and lowering the dynamic collection tray 7 based on the sensor signal feedback. When the sensor detects that the carbonization of the material is qualified, the dynamic collection tray 7 moves downward, and the arc cover 73 enters the upper middle part of the swirl. The carbonized raw materials enter the arc cover 73 through the air inlet hole 74, are screened by the filter 72, and are collected in the sealed storage bin 103.

[0060] The pressure air pump 3 and the feed air pump 9 work together to ensure air circulation and continuous drying and carbonization processes. The airflow passes through the drying box 15 to remove moisture components, improve the airflow drying efficiency, ensure that the entire device always maintains a dry and oxygen-free environment, and continuously carries out the rotation of drying, carbonization and collection of raw materials. According to the real-time monitoring results, the heating temperature, airflow speed and other parameters can be dynamically adjusted;

[0061] The carbonized raw materials enter the sealed storage bin 103 through the discharge pipe 11, ensuring that the finished product is not affected by the outside air and maintains its quality. Through the above steps, the biomass absorbing material preparation device can efficiently and continuously produce high-quality biomass absorbing materials, ensuring that the product is dried and carbonized in an oxygen-free environment, thereby maintaining the excellent physical and chemical properties of the material.

[0062] Preferably, when the air supply pump 3 does not deliver oxygen-free gas to the heating chamber 21 of the heating disc 2, the raw materials in the heating carbonization chamber 104 may enter the heating chamber 21 through the conical air nozzle 4. The improper entry of the raw materials may cause contamination of the heating chamber 21, which not only affects the use effect of the heating disc 2 but also requires cleaning of the heating chamber 21. Therefore, an adaptive protection component is also provided, such as Figure 9As shown, a movable air hole plate 18 is provided in the heating chamber 21, and a plurality of air holes 19 are provided on the movable air hole plate 18, which are staggered with the air inlet of the conical air nozzle 4, and a piston rod 17 is fixedly connected to the top of the heating chamber 21 of the heating disc 2, and a piston cylinder 16 is matched with the piston rod 17, and the movable air hole plate 18 is fixedly connected to the piston cylinder 16, and the top of the movable air hole plate 18 is flush with the top of the piston cylinder 16, and a top spring 21 is provided in the upper chamber of the piston cylinder 16, and the top spring 21 is sleeved on the piston rod 17, and the bottom of the top spring 21 is connected to the piston rod 17, and the top of the top spring 21 is connected to the top of the piston cylinder 16, and the lower chamber of the piston cylinder 16 is connected to the heating chamber 21, and the upper chamber of the piston cylinder 16 is connected to the air duct 2 92 through a pipeline.

[0063] When the pressure air pump 3 does not supply oxygen-free gas to the heating chamber 21 of the heating disc 2, the heating chamber 21 is in a pressure-free state, and the top spring 21 in the upper chamber of the piston cylinder 16 pushes the movable air hole plate 18 upward, so that the movable air hole plate 18 is sealed against the top of the heating disc 2, and the air inlet of the conical air nozzle 4 of the heating disc 2 is closed to prevent raw materials from falling into the heating chamber 21 of the heating disc 2.

[0064] When the pressure pump 3 delivers oxygen-free gas to the heating chamber 21 of the heating disc 2, the heating chamber 21 is pressurized. The air pressure enters the lower chamber of the piston cylinder 16, pushing the piston cylinder 16 downward and simultaneously driving the movable air hole plate 18 downward. At the same time, the gas in the upper chamber of the piston cylinder 16 is pressed into the air duct 2 92, and the top spring 21 is also compressed. At this time, the movable air hole plate 18 and the top of the heating disc 2 form an air intake gap 20, and the air enters and exits the conical air nozzle 4 through the air hole 19.

[0065] Through the linkage between the top spring 21 and the piston cylinder 16, the opening and closing of the air inlet can be automatically controlled by utilizing the change in air pressure, thereby improving the automation and reliability of the device, and preventing raw materials from entering the heating chamber 21 at inappropriate times, thereby avoiding contamination and cleaning problems of the heating chamber 21 that may be caused by improper entry of raw materials.

[0066] Example 2: A device for preparing a biomass absorbing material in this embodiment is described with the differences from Example 1 as the center.
