[0037] Embodiment 1

[0038] In this embodiment, a weighing system and a flow rate control device are arranged in the vacuum adsorption equipment, so that the material can be weighed while feeding, and the feeding flow rate can be adjusted as needed. At the same time, a valve control device is connected to the outlet below the weighing component to improve the air tightness of the silo below, ensuring that the silo can desorb the material under a vacuum state, and a variety of sensors and online monitoring systems are used to provide real-time feedback on the feeding process, thereby improving feeding accuracy, saving labor costs, reducing errors in manual operations, and realizing continuous operation of vacuum desorption.

[0039] A feeding system for a vacuum desorption device, such as Figure 1 As shown, it includes: a feeding component 1, a silo 2, a controller 3, a weighing component 4 and a vacuum desorption component 5;

[0040] A feeding port connected to the feeding assembly 1 is provided on the top of the silo 2, and the feeding assembly 1 is electrically connected to the controller 3;

[0041] The silo 2 is provided with at least two observation windows 6 from top to bottom, and the silo 2 is also provided with at least two material level meters 7 from top to bottom, and each material level meter 7 is electrically connected to the controller 3;

[0042] The weighing component 4 is connected to the silo 2 to weigh the silo 2, and the weighing component 4 is electrically connected to the controller 3;

[0043] A switch-controllable discharging assembly 8 is provided at the lower part of the silo 2 . The discharging assembly 8 is connected to the vacuum desorption assembly 5 , and the discharging assembly 8 is electrically connected to the controller 3 .

[0044] This embodiment provides an efficient and accurate feeding system for vacuum desorption equipment, which mainly includes five core parts: feeding component 1, silo 2, controller 3, weighing component 4 and vacuum desorption component 5. These components work together to ensure continuous, stable and accurate supply of materials during vacuum desorption.

[0045] First, the feeding component 1 is responsible for conveying the material to be processed from the outside to the silo 2. A feeding port is designed on the top of the silo 2, and the feeding port is interconnected with the feeding component 1 to ensure that the material can smoothly enter the silo 2. The feeding component 1 is electrically connected to the controller 3, and the controller 3 can adjust the feeding speed and quantity according to the preset program or real-time feedback to achieve precise control of the feeding component 1.

[0046] Further, in order to facilitate observation and monitoring of the state of the material in the silo 2, as shown in the attached Figure 2 As shown, the silo 2 is provided with at least two observation windows 6 from top to bottom. These observation windows 6 are made of transparent material, and the accumulation and flow state of the materials in the silo 2 can be clearly seen. At the same time, the silo 2 is also provided with at least two level meters 7 from top to bottom, which can detect the height or volume of the materials in the silo 2 in real time, and transmit the detected data to the controller 3. Based on these data, the controller 3 can accurately determine the remaining amount and supply speed of the material, so as to ensure the continuity and stability of the material supply; in order to accurately measure the weight of the material, the silo 2 is connected to the weighing component 4. The weighing component 4 can monitor the weight of the material in the silo in real time and send the weighing data to the controller 3. According to the weighing data, the controller 3 can further adjust the feeding speed and quantity of the feeding component 1 to ensure the accuracy of the material supply.

[0047] When the material in the silo 2 reaches the preset desorption condition, the controller 3 will control the switch-controllable discharge assembly 8 to start working. The discharge assembly 8 is located at the lower part of the silo 2 and is connected to the vacuum desorption assembly 5. Under the control of the controller 3, the discharge assembly 8 will transport the material to the vacuum desorption assembly 5 for processing at a preset rate. In actual applications, the discharge assembly 8 and the controller 3 are also electrically connected to ensure that the controller 3 can control the working state of the discharge assembly 8 in real time, and the discharge rate can be controlled by the controller 3.

[0048] In a specific embodiment, the feed assembly 1 includes a filter element 11, one side of the filter element 11 is connected to the feed assembly 1, and the other side is connected to the silo 2;

[0049] The feeding assembly 1 is provided with an air outlet which is connected with the silo 2 .

[0050] In this embodiment, in order to ensure that the material entering the silo 2 is not contaminated by impurities, the feeding assembly 1 is specially designed with a filter 11. The filter 11 plays a key role in screening and cleaning, ensuring that the material can remove dust, particles or other unnecessary impurities that may be attached during the conveying process.

[0051] One side of the filter element 11 is connected to the feeding assembly 1, and the other side is connected to the feed port of the silo 2, ensuring that when the material is transported to the silo 2 through the feeding assembly 1, it must pass through this filtering link to form a smooth and continuous material conveying channel.

[0052] In a specific embodiment, the setting position of each observation window 6 corresponds to the setting position of each material level meter 7, and the corresponding observation windows 6 and material level meters 7 are located in the same horizontal plane.

[0053] In this embodiment, in order to improve the accuracy and convenience of material status monitoring in the silo 2, the setting positions of each observation window 6 and the setting positions of each level meter 7 are carefully arranged to ensure a one-to-one correspondence between them, so that each observation window 6 is closely matched with the corresponding level meter 7 thereunder, and jointly acts on the materials on the same horizontal plane in the silo 2.

[0054] Specifically, the corresponding observation windows 6 and the level meter 7 are located at the same horizontal plane. Such a layout allows the operator to intuitively see the actual state of the material height or volume detected by the level meter 7 through the observation window 6. When the level meter 7 detects that the material height reaches or exceeds the preset threshold, the operator can immediately confirm this state through the corresponding observation window 6, so as to make adjustments or take corresponding operations in time. In addition, this layout also helps to improve the accuracy of material monitoring. Since the observation window 6 and the level meter 7 are located at the same horizontal plane, the material states they monitor are highly consistent. Therefore, when the level meter 7 sends data, the operator can more accurately judge the actual state of the material, thereby avoiding production problems caused by errors or misjudgments.

[0055] In a specific embodiment, the discharge assembly 8 includes a soft buffer flange 81, a first valve 82 and a second valve 83 connected in sequence, the inlet of the soft buffer flange 81 is connected to the discharge port of the silo 2, and the outlet of the second valve 83 is connected to the feed port of the vacuum desorption assembly 5;

[0056] The first valve 82 and the second valve 83 are electrically connected to the controller 3 respectively.

[0057] The soft buffer flange 81 is the starting part of the discharge assembly 8, and its entrance is closely connected to the discharge port of the silo 2. The soft buffer flange 81 can effectively absorb the impact force generated by the material during the flow process, avoiding the material directly impacting the equipment and causing damage, and also reduces the noise during the flow of the material. In addition, the soft material of the soft buffer flange 81 also has a certain sealing property, which can prevent material leakage to a certain extent and ensure the stable operation of the system.

[0058] Specifically, the first valve 82 includes a variable frequency discharge valve, and the second valve 83 includes a solenoid valve. The variable frequency discharge valve is used as the first valve 82, and its design of being electrically connected to the controller 3 allows the operator to remotely control the variable frequency discharge valve through the controller 3, so that it can adjust its own rotation speed according to the instructions sent by the controller 3, thereby achieving precise control of the discharge rate, and can flexibly adjust the material discharge speed according to production needs to avoid the material from flowing out too fast or too slow, thereby ensuring the stability and continuity of the production process.

[0059] At the same time, the intelligent design of the variable frequency discharge valve also greatly reduces the need for human intervention. The operator only needs to set the parameters of the discharge rate on the controller 3, and the variable frequency discharge valve can automatically work according to these parameters without frequent manual adjustment. This not only improves work efficiency, but also reduces the labor intensity of operators; the second valve 83, as a solenoid valve, is also connected to the controller 3 through an electrical connection. The solenoid valve has the characteristics of fast response speed and precise control. It can be quickly opened or closed after receiving the command of the controller 3, ensuring that the material can enter the vacuum desorption component 5 accurately and quickly when needed.

[0060] Through the dual control of the first valve 82 and the second valve 83, the discharging assembly 8 not only realizes the precise control of the material flow, but also improves the safety and stability of the system. When the system fails or needs maintenance, the controller 3 can quickly close the first valve 82 and the second valve 83 to cut off the material flow and prevent accidents. At the same time, this design also facilitates the daily maintenance and overhaul of the equipment, and improves the maintainability and service life of the equipment.

[0061] In a specific embodiment, as shown in the attached Figure 4 As shown, the vacuum desorption assembly 5 includes a desorption silo 512 and a discharge fan 52, and a feed port connected to the silo 2 is provided at the top of the desorption silo 512;

[0062] The unloading fan 52 is provided with an air outlet connected to the desorption bin 512 , and the unloading fan 52 is electrically connected to the controller 3 .

[0063] In this embodiment, the vacuum desorption component 5 mainly includes two key parts: a desorption silo 512 and a discharge fan 52. As the main place for the entire desorption process, the design of the desorption silo 512 takes into account the smoothness of material flow and the maximization of the desorption effect. A feed port is cleverly set at the top of the desorption silo 512, and this feed port is accurately connected with the silo 2 to ensure that the material can smoothly enter the desorption silo 512 for subsequent desorption treatment; at the same time, the discharge fan 52 also ensures the efficiency of the entire desorption process. The discharge fan 52 is electrically connected to the controller 3, so that the controller 3 can monitor the operating status of the discharge fan 52 in real time and accurately control it according to actual conditions. This intelligent design makes the entire desorption process more flexible and efficient, and also greatly improves the stability and reliability of the equipment.

[0064] In a specific embodiment, a level meter 9 for detecting whether the silo 2 is level is also included.

[0065] In this embodiment, in order to improve the overall stability and efficiency of the vacuum desorption equipment, a level meter 9 is added to detect whether the silo 2 is horizontal. The level meter 9 is a high-precision measuring tool that can accurately detect whether the silo 2 is in a horizontal state. Its installation position is usually selected on the outside or top of the silo 2 so that the inclination of the silo can be fully and accurately monitored. The working principle of the level meter 9 is based on the principle of gravity sensing. The direction of gravity is sensed by the internal measuring element to determine whether the silo 2 is horizontal. The level meter 9 can detect the inclination of the silo 2 at the first time, thereby avoiding problems such as poor material flow and equipment damage caused by the inclination. If the silo 2 is tilted, it will also cause errors in the weighing data measured by the weighing component 4, thereby affecting the operation of the entire equipment. At the same time, the real-time monitoring function of the level meter 9 also enables the operator to grasp the status of the silo at any time to ensure the stable operation of the entire vacuum desorption equipment.

[0066] In addition, the level meter 9 can also be electrically connected to the controller 3 to achieve real-time data transmission and automatic processing. When the level meter 9 detects that the tilt of the silo 2 exceeds the set threshold, the controller 3 will immediately receive an alarm signal and automatically take corresponding measures, such as stopping feeding, adjusting the position of the equipment, etc., to ensure the safety and stable operation of the entire system.

[0067] In a specific embodiment, as shown in the attached Figure 3 As shown, the weighing assembly 4 includes at least two weighing columns, each of which is located below the silo 2 , and the axial direction of the weighing column is parallel to the gravity direction of the silo 2 .

[0068] In this embodiment, the weighing assembly 4 is a weighing device composed of four weighing columns, which are cleverly placed directly below the silo 2 to support and measure the weight of the silo and the material inside it. The axial direction of the weighing column is parallel to the gravity direction of the silo 2, which means that the weighing column directly bears the weight of the silo and the material inside it. This direct force-bearing method avoids the transmission and dispersion of force, thereby improving the accuracy and stability of the measurement. At the same time, this design also ensures the stability and durability of the weighing column during long-term operation.

[0069] In practical applications, the weighing assembly 4 is electrically connected to the controller 3 to achieve real-time data transmission and automatic processing. When the weight of the material in the silo 2 changes, the weighing column will immediately sense the change and transmit the data to the controller 3. The controller 3 will analyze and calculate based on the received data, thereby achieving precise control of the desorption process.

[0070] In a specific embodiment, at least one sealing valve 10 is further included. The sealing valve 10 is arranged on the vacuum desorption component 5 and is electrically connected to the controller 3 respectively, so as to realize vacuum desorption of the vacuum desorption component 5 under the control of the controller 3 .

[0071] In this embodiment, a sealing valve 10 is also included on the vacuum desorption component 5 to ensure the efficiency and sealing of the vacuum desorption component 5 during the desorption process. Specifically, the sealing valve 10 is designed as a butterfly valve. The butterfly valve is an ideal choice in the vacuum desorption process due to its unique structure and efficient working mode. The valve plate of the butterfly valve can rotate around its axis to open and close the valve. In the closed state, the valve plate of the butterfly valve can fit tightly against the valve seat to form a reliable seal, effectively prevent gas leakage, and ensure that the vacuum desorption component 5 can maintain a stable vacuum environment during the desorption process.

[0072] Under the control of the controller 3, the sealing valve 10 can accurately control the start and end of the desorption process. When the controller 3 receives the instruction to start desorption, it will send an opening signal to the sealing valve 10 to rotate the valve plate of the butterfly valve to the open position, allowing the gas and residue to be discharged from the vacuum desorption component 5. When the desorption process is completed, the controller 3 will send a closing signal to the sealing valve 10 again, so that the valve plate of the butterfly valve returns to the closed state and re-forms the seal.

[0073] In a specific embodiment, the controller 3 includes a button group 31, and the button group 31 includes a start button, and / or a stop button, and / or an emergency stop button.

[0074] In this embodiment, in order to achieve a more efficient operating experience, the controller 3 is specially equipped with a button group 31, which includes a variety of function buttons to meet different operating requirements, including but not limited to a start button, a stop button, and an emergency stop button.

[0075] The start button starts the operation of the vacuum desorption equipment. When the operator needs to start the desorption process, just press the start button lightly, the controller 3 will receive the instruction and start the corresponding equipment components, such as the vacuum pump, sealing valve, etc., to start the desorption operation; the stop button is used to stop the operation of the equipment when necessary. When the desorption process is completed or an abnormal situation occurs and the equipment needs to be stopped, the operator can press the stop button, the controller 3 will immediately receive the stop instruction, and shut down the relevant equipment components to ensure that the equipment stops safely; the emergency stop button is a special button for emergency stopping of the equipment. When the equipment has a serious fault or safety hazard, the operator can immediately press the emergency stop button, the controller 3 will immediately cut off all power supplies, and the equipment will stop running immediately to avoid danger.

[0076] The utility model arranges a weighing system and a flow rate control device in the vacuum adsorption equipment, so that the material can be weighed while feeding, and the feeding flow rate can be adjusted as needed. At the same time, the outlet below the weighing component is connected with a valve control device, so as to improve the air tightness of the silo below, ensure that the silo can desorb the material under a vacuum state, and adopt a variety of sensors and online monitoring systems to feedback the feeding process in real time, improve the feeding accuracy, save labor costs, reduce the error of manual operation, and realize the continuous operation of vacuum desorption.

[0077] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
