[0013] Preferably, the method of using the pneumatic conveying equipment is as follows: S1. First, move the control cabinet between the storage point of condiments and other materials and the processing station to be transported, and add pipeline connections according to the needs of use to ensure that the material source can be connected to the target station; S2. Press the start button, turn on the power, and set the initial operating parameters through the touch screen; S3. After the motor is started, it drives the motor wheel to rotate, and then the fan wheel can rotate to generate airflow under the action of the belt.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1.

Since the frequency converter can accurately control the motor speed and the airflow speed generated by the fan, the uniformity of condiments and other materials during the transportation process can be ensured, so that condiments and other materials always maintain a stable transportation speed and state in the pipeline, avoiding the accumulation of materials in the pipeline or the situation where the flow rate is fast or slow, thereby ensuring uniform feeding.

[0016] 2. The present invention reduces the probability of material blockage or uneven flow rate in the pipeline due to uneven pressure through the pressure regulating function of the vacuum chamber, so that the material can be transported out evenly and stably. The vacuum chamber can balance the pressure by adjusting the vacuum volume to prevent local pressure from being too high or too low and affecting the normal transportation of the material. At the same time, it can ensure that the material can be transported evenly in the pipeline to avoid material accumulation or uneven flow rate in the pipeline.

[0017] 3. During the conveying process, the present invention monitors the conveying parameters and operating status in real time through the touch screen. If abnormal conditions such as uneven conveying or pressure fluctuations are found, the machine should be stopped immediately for inspection, and the parameter settings on the touch screen should be adjusted as needed.

[0018] 4. The present invention ensures that the fan can work stably for a long time by setting the oil filling port. The oil filling ports in different positions can correspond to different lubrication demand points, so as to realize precise lubrication.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] See also Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment: a condiment feeding pneumatic conveying equipment, comprising a control cabinet 1, a human-machine interface 2 is arranged on the front of the control cabinet 1, the human-machine interface 2 interacts with the control system, the control system comprises a conveying module, a feeding module, a monitoring module and a maintenance module, the conveying module comprises a conveying pipeline and an air source device, the feeding module uses a feeding mechanism to feed the raw materials into the conveying pipeline, the monitoring module uses a sensor and a controller to monitor the feeding and feeding process, the maintenance module is used to regularly perform maintenance on the condiment feeding pneumatic conveying equipment, the maintenance content includes cleaning the accumulated material in the conveying pipeline, checking and replacing the worn parts, and lubricating the moving parts of the equipment, the bottom of the control cabinet 1 A shelf 3 is installed on the wall, and the air source device includes a motor 4 and a fan 5 installed on the top of the shelf 3. The fan 5 is located in front of the motor 4. A motor wheel 7 is installed at the output end of the motor 4. A rotating shaft is installed on the output shaft of the fan 5. A fan wheel 6 is installed at one end of the rotating shaft. Belts are sleeved on the outer surfaces of the fan wheel 6 and the motor wheel 7. When the motor 4 is started, the motor wheel 7 rotates, and the fan wheel 6 is driven to rotate by the belt. The human-machine interface 2 includes a touch screen and buttons. The buttons are located below the touch screen. The buttons include a start button, a run button, a stop button and an emergency stop button. A frequency converter 12 is installed on the front wall of the control cabinet 1. The frequency converter 12 is electrically connected to the motor 4 and is used to adjust the speed of the motor 4.

[0025] Furthermore, the conveying pipeline adopts a material with a smooth inner wall to minimize the friction resistance of the material during the conveying process, ensuring that the raw materials can flow smoothly from the starting point to the end point. The pipeline layout with different diameters and directions is adapted to different conveying scenarios. For example, when long-distance transportation is required, the use of a larger diameter pipeline can reduce the attenuation of air flow velocity and maintain the suspension state of the material. At the turning point, the special curve design combined with a reasonable diameter transition can effectively avoid material accumulation and blockage. The air source device is the power source for transportation, and is mainly composed of a motor 4 and a fan 5. As the core driving component, the motor 4 efficiently converts electrical energy into mechanical energy through the motor wheel 7 and the fan wheel 6 of the fan 5 with the help of belt transmission, driving the fan 5 to rotate at high speed. The strong airflow generated by the fan 5 flows into the conveying pipeline, providing the raw materials with the power to move forward. The air volume and air pressure can be adjusted according to the actual transportation needs, such as by changing the speed of the motor 4, with the help of the inverter 12 for precise control, to adapt to raw materials of different particle sizes and humidity and different transportation distances. The feeding mechanism dynamically adjusts the suction volume through the arranged suction chamber 8, cleverly balancing the pressure in the conveying pipeline, so that the raw materials in the feeding chamber 9 can enter the acceleration chamber 10 through the suction chamber 8 evenly and orderly, and are transported to the storage bin through the pipeline under the wind blowing of the Roots blower.

[0026] The monitoring module collects various key data in the feeding and feeding process in real time through the deployed sensors. For example, the material flow sensor accurately monitors the rate at which the raw materials enter the pipeline, the air flow velocity sensor always grasps the dynamic changes of the air flow in the conveying pipeline, and the pipeline pressure sensor closely monitors the pressure conditions at various locations in the pipeline. The controller is used to receive massive signals from the sensors and use advanced algorithms for analysis and processing. For example, if a sudden decrease in material flow may indicate a feed blockage, the air flow speed is too slow to meet the transportation requirements, or a sudden increase in pipeline pressure poses a safety hazard, the controller will immediately feedback the abnormal information to the human-machine interface 2 so that the operator can take corresponding measures in time.

[0027] The maintenance module scientifically formulates the maintenance cycle according to factors such as the equipment's operating time, work intensity, and past fault records. The primary task of maintenance is to clean the accumulated materials in the conveying pipeline. Over time, the sticky components or fine particles in the raw materials may adhere to and accumulate on the inner wall of the pipeline. Regular cleaning can ensure that the pipeline is unobstructed and maintain the best conveying efficiency. During frequent mechanical movements, the blades of the fan 5, the bearings of the motor 4, and the rotating parts of the feeding mechanism are prone to wear. Timely replacement of worn parts can effectively avoid equipment failures and ensure operational reliability. Regular lubrication of the rotating parts of the motor 4, fan 5, feeding mechanism, etc., such as using the oil filling port 13 on the fan 5, judging the oil level based on the oil level sight glass 14 and replenishing it in time, and regularly replacing the aged lubricating oil with the help of the oil drain port 15 can significantly reduce the friction coefficient between components and extend the service life of the equipment.

[0028] When the equipment is in a shutdown state and is ready to start running, the operator presses the start button to start the startup program of the equipment. After the equipment is started, if it is necessary to make it enter a stable running state, the operator will press the run button. At this time, the equipment will work according to the preset initial operating parameters, such as the fan 5 starts to rotate at a basic speed to generate a certain intensity of airflow, and the feeding mechanism also starts to enter the initial feeding mode to feed the raw materials into the conveying pipeline at a relatively stable rate. When the equipment completes the conveying task or needs regular maintenance, overhaul and other operations, the operator presses the stop button. The whole process is an orderly and gradually lowering process of the equipment operation state to avoid mechanical shock and material residue caused by sudden shutdown. During the operation of the equipment, if there is an emergency, such as severe blockage of materials causing a sharp increase in the pressure of the conveying pipeline, abnormal heating or smoking of the motor 4, abnormal vibration of the equipment, etc., which may endanger the safety of the equipment and the personal safety of the operator, the operator can immediately press the emergency stop button. After pressing this button, the equipment will immediately cut off all power supplies, so that the motor 4, the fan 5, the feeding mechanism and other related electrical equipment will stop running instantly, thereby minimizing possible dangers and losses.

[0029] The frequency converter 12 is electrically connected to the motor 4 and can change the power supply frequency of the motor 4. During the pneumatic conveying of the condiment feeding, the airflow speed and pressure generated by the fan 5 need to be adjusted according to different working conditions, such as conveying raw materials of different particle sizes, different conveying distances, different material humidity and other factors. Since the speed of the fan 5 directly affects the characteristics of the airflow, and the speed of the fan 5 is driven by the motor 4, the speed of the motor 4 can be adjusted by the frequency converter 12 to achieve precise control of the airflow of the fan 5. For example, when the particle size of the conveyed raw material is large, the speed of the motor 4 can be increased by the frequency converter 12, so that the fan 5 generates a stronger airflow to ensure that the material can be smoothly conveyed in the pipeline. When the conveying distance is short and the material particle size is small, the speed of the motor 4 can be appropriately reduced to save energy and reduce the wear of the material in the pipeline. In addition, during the start-up and shutdown of the equipment, the frequency converter 12 can also realize the soft start and soft stop function of the motor 4, that is, slowly increase or decrease the speed of the motor 4, avoiding the large current shock and mechanical shock during direct start-up and shutdown, and extending the service life of the equipment.

[0030] See also Figure 3 and Figure 4 An embodiment of the present invention is a pneumatic conveying device for feeding condiments, wherein the feeding mechanism comprises an exhaust chamber 8 installed on the top of a fan 5, the exhaust chamber 8 can balance the pressure of the conveying pipeline by adjusting the exhaust volume, and a feeding chamber 9 is installed on the top of the exhaust chamber 8.

[0031] Furthermore, the exhaust chamber 8 can utilize the airflow generated by the fan 5 to work. The airflow provided by the fan 5 is the power source of the entire pneumatic conveying system. The exhaust chamber 8 controls the pressure in the conveying pipeline by adjusting this airflow. The feeding chamber 9 is the entrance for materials to enter the conveying system. The power is transmitted to the fan 5 through the connection between the motor wheel 7 and the fan wheel 6. When the fan 5 is started, the generated airflow enters the conveying pipeline. During the conveying process, due to the influence of the pipeline length, bends and the material itself, the pressure at different positions in the pipeline may be unbalanced. If the pressure is too high in a certain part of the pipeline, the exhaust chamber 8 can increase the exhaust volume, extract the excess gas, and reduce the pressure in that part. Conversely, if the pressure in a certain part is too low, the exhaust chamber 8 can reduce the exhaust volume, allowing more airflow to flow to that part, thereby increasing the pressure, so that the material enters the conveying pipeline under the action of a suitable airflow, and the uniform pressure environment ensures that the material can be transported in the pipeline at a stable speed and state, which to a certain extent guarantees the uniformity and stability of material transportation.

[0032] See also Figure 4 and Figure 6An embodiment of the present invention is a pneumatic conveying device for feeding condiments, wherein the conveying pipeline includes an acceleration chamber 10 installed at the bottom of a rack 3, the top of the acceleration chamber 10 is connected to the air outlet of a blower 5, and connecting pipes 11 are installed at both ends of the acceleration chamber 10, one end of one group of connecting pipes 11 passes through the back of a control cabinet 1 and is connected to the output end of the Roots blower, and one end of another group of connecting pipes 11 passes through an outer wall of one side of the control cabinet 1 and is connected to a connecting pipe, and one end of the connecting pipe is connected to an external storage bin.

[0033] Further, the acceleration chamber 10 is installed at the bottom of the storage rack 3, and the top of the acceleration chamber 10 is connected to the air outlet of the fan 5. When in use, the airflow generated by the fan 5 can directly enter the acceleration chamber 10. The function of the acceleration chamber 10 is to accelerate the airflow and provide sufficient power for the transportation of materials in the pipeline. Connecting pipes 11 are installed at both ends of the acceleration chamber 10. One group of connecting pipes 11 is connected to the output end of the Roots blower, and the other group of connecting pipes 11 is connected to the external storage bin through the connecting pipe. The Roots blower serves as the main power source. The airflow generated by the Roots blower enters the acceleration chamber 10 through the connecting pipe 11. After acceleration, the airflow and the material are transported to the storage bin through another group of connecting pipes 11 and the connecting pipe. After the Roots blower is started, a stable airflow is generated, and the airflow enters the acceleration chamber 10 through the connecting pipe 11. In the acceleration chamber 10, the material is carried and accelerated by the airflow, and then transported to the target position along the pipeline, which can improve the transportation efficiency to a certain extent.

[0034] See also Figure 3 and Figure 5 An embodiment of the present invention is a pneumatic conveying device for feeding condiments, wherein an oil filling port 13 is provided on the top of the fan 5, and an oil level observation mirror 14 and an oil drain port 15 are provided on the outer surface of the fan 5. The oil level observation mirror 14 is used to check the oil level of the lubrication parts corresponding to each oil filling port 13, and the oil drain port 15 is located below the oil level observation mirror 14.

[0035] Furthermore, during the operation of the fan 5, its internal rotating parts such as the bearings of the fan wheel 6 require good lubrication to reduce friction, reduce wear and ensure smooth operation. The setting of the oil filling port 13 is to facilitate the addition of lubricating oil to these key parts that need lubrication to ensure that the fan 5 can work stably for a long time. The oil filling ports 13 at different positions can correspond to different lubrication demand points, thereby achieving precise lubrication. The oil level observation mirror 14 plays a role in visual monitoring. Since the amount of lubricating oil inside the fan 5 needs to be maintained at an appropriate level, too little may lead to insufficient lubrication, and too much may cause leakage and other problems. Through the oil level observation mirror 14, the operator can intuitively view the oil level of the lubricating parts corresponding to each oil filling port 13, and then timely grasp the status of the lubricating oil inside the fan 5, so as to make corresponding maintenance decisions. After the lubricating oil has been used for a period of time, its performance will decline. For example, it may be mixed with impurities or oxidized. Regular replacement is a necessary measure to ensure the good operation of the fan 5. The old lubricating oil can be completely discharged through the oil drain port 15 to prepare for the injection of new qualified lubricating oil.

[0036] When replacing the lubricating oil, first prepare an oil receiving container and place it under the oil drain port 15, open the valve or plug or other oil drain device of the oil drain port 15, and let the old lubricating oil flow into the container under the action of gravity until the old oil is basically drained. After that, close the oil drain port 15, and then inject new lubricating oil that meets the requirements through the oil filling port 13. At the same time, observe the oil level through the oil level sight glass 14 to ensure that the amount of oil injected is appropriate. To a certain extent, it can provide convenient and effective protection for the lubrication maintenance of the fan 5, help to extend the service life of the fan 5, and ensure the reliable operation of the entire pneumatic conveying equipment.

[0037] Working principle: First, check the oil level of the lubricating parts corresponding to each oil filling port 13 through the oil level observation mirror 14. If the oil level is insufficient, add an appropriate amount of lubricating oil through the oil filling port 13. Then move the control cabinet 1 between the storage point of condiments and other materials and the processing station to be transported, and add pipeline connections according to the needs of use to ensure that the material source can be connected to the target station. Press the start button, turn on the power, set the initial operating parameters through the touch screen, and after the motor 4 is started, it drives the motor wheel 7 to rotate, and then the fan wheel 6 can rotate to generate airflow under the action of the belt. Under the action of the airflow generated by the fan 5, the condiments The materials are carried by the airflow and enter the acceleration chamber 10. At the same time, the raw materials can be transported along the pipeline under the promotion of the Roots blower. During the transportation process, the operating status of the equipment can be viewed in real time through the touch screen, and the transportation of the materials in the pipeline can be closely monitored through the monitoring module. If the raw materials are found to be blocked or the transportation is uneven, the equipment is immediately stopped for inspection, and the relevant parameters of the feeding device or the air source device are adjusted. When the transportation task is completed, the stop button is pressed to turn off the equipment, and the old lubricating oil is regularly discharged through the oil drain port 15, and new lubricating oil is added through the oil filling port 13 to ensure the long-term stable operation of the equipment.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
