[0024] The lung suction mechanism includes a suction tube 31 and a connecting tube 32 connecting the suction tube 31 and the separation tank 1. The connecting tube 32 can be a flexible tube. In this embodiment, the lung suction mechanism includes two suction tubes 31 and two connecting tubes 32 corresponding to the two suction tubes 31. A differential pressure sensor 33 is provided inside the suction tube 31 of the lung suction mechanism to detect the differential pressure between the tube opening of the suction tube 31 and the target lung. The differential pressure sensor 33 can be a thin-film differential pressure sensor.

[0025] The separation tank 1 is used for the storage and separation of poultry lungs. The side wall of the separation tank 1 is sealed to a three-way pipe 12. One branch of the three-way pipe 12 is connected to one connecting pipe 32 of the lung suction mechanism, and the other branch is connected to another connecting pipe 32 of the lung suction mechanism. A pressure sensor 11 is installed inside the separation tank 1 to detect the internal pressure. An ozone generator 4 is connected to the separation tank 1 via a pipe and is electrically connected to a control mechanism 5. The control mechanism 5 controls the ozone generator 4 to introduce ozone gas into the separation tank 1 for sterilization, preventing Salmonella contamination.

[0026] The parallel vacuum pump set includes a main vacuum pump 21 and an auxiliary vacuum pump 22. The main vacuum pump 21 and the auxiliary vacuum pump 22 are connected in parallel and are both connected to the separation tank 1 through the vacuum tube 23. The main vacuum pump 21 is used to continuously extract air through the vacuum tube 23 to create a negative pressure in the separation tank 1, so as to create a significant air pressure difference between the inlet of the suction tube 31 and the target lung. The auxiliary vacuum pump 22 is used to intelligently compensate for air pressure fluctuations in the separation tank 1 in order to maintain the set negative pressure in the separation tank 1.

[0027] Preferably, the control mechanism 5 is electrically connected to the main vacuum pump 21 and the auxiliary vacuum pump 22 to control the main vacuum pump 21 and the auxiliary vacuum pump 22 to extract gas from the separation tank 1. The control mechanism 5 can be a PLC controller or a microcontroller. The differential pressure sensor 33 and the pressure sensor 11 are electrically connected to the control mechanism 5. The pressure sensor 11 feeds back the pressure signal inside the separation tank 1 to the control mechanism 5 in real time, and the differential pressure sensor 33 feeds back the pressure difference signal between the inlet of the suction tube 31 and the target lung to the control mechanism 5 in real time.

[0028] Preferably, both the vacuum tube 23 and the suction tube 31 are equipped with valves, which can be solenoid valves. The valves are electrically connected to the control mechanism 5, and the opening and closing of the valves are controlled by the control mechanism 5. When sucking lungs, first close the valve on the suction tube 31, open the valve on the vacuum tube 23 and turn on the main vacuum pump 21 to make the negative pressure in the separation tank 1 reach the set value; then close the valve on the main vacuum pump 21 and the vacuum tube 23, then open the valve on the suction tube 31 and insert the suction tube 31 into the poultry to suck lungs.

[0029] Preferably, the separation tank 1 is connected to a booster pump via a pipeline, and the separation tank 1 is connected to a collection box 8 via a discharge pipe 81. A discharge valve 82 is provided on the discharge pipe 81.

Then the discharge valve 82 is opened, and the lungs are discharged to the collection box 8 using the positive pressure.

[0030] Preferably, the control mechanism 5 includes a receiving unit 51, a preset unit 52, a comparison unit 53, and a control unit 54. The comparison unit 53 is electrically connected to the receiving unit 51, the preset unit 52, and the control unit 54, respectively. The receiving unit 51 is electrically connected to the pressure sensor 11 to receive the internal pressure signal of the separation tank 1, and the receiving unit 51 is electrically connected to the differential pressure sensor 33 to receive the differential pressure signal. The preset unit 52 presets a predetermined pressure value and a differential pressure value. The comparison unit 53 is used to compare the internal pressure value of the separation tank 1 and the differential pressure value with the predetermined pressure value and the differential pressure value, respectively.

[0031] Furthermore, the air pressure value output by the pressure sensor 11 and the air pressure difference signal output by the differential pressure sensor 33 are analog signals. The receiving unit 51 is equipped with an analog-to-digital converter. The input terminal of the analog-to-digital converter is electrically connected to the pressure sensor 11 and the differential pressure sensor 33 to receive the analog signals and convert them into digital signals for comparison. The input terminal of the comparison unit 53 is connected to the output terminal of the analog-to-digital converter, and the output terminal of the comparison unit 53 is connected to the control unit 54. When the air pressure inside the separation tank 1 is less than the predetermined air pressure value, the control unit 54 controls the main vacuum pump 21 to start and extract the gas inside the separation tank 1 until the air pressure inside the separation tank 1 is lower than or equal to the predetermined air pressure value, ensuring that the separation tank 1 always maintains a predetermined negative pressure. The control unit 54 is electrically connected to the differential pressure sensor 33, the pressure sensor 11, the main vacuum pump 21, the auxiliary vacuum pump 22, and the ozone generator 4.

[0032] In use, the main vacuum pump 21 is activated, creating a high vacuum state inside the separation tank 1. The suction tube 31 of the lung suction mechanism is inserted into the slaughtered poultry to suction the lungs. Under pressure differential conditions, the poultry lungs are drawn into the separation tank 1 through the suction tube 31 and connecting tube 32 for separation and storage. The pressure sensor 11 detects the internal pressure value of the separation tank 1 and sends the pressure signal to the control mechanism 5. The pressure differential sensor 33 provides real-time feedback of the pressure difference between the suction tube 31 opening and the target lung to the control mechanism 5. When fluctuations or decreases are detected in the internal pressure value of the separation tank 1 and the pressure difference between the suction tube 31 opening and the target lung, the control mechanism 5 activates the auxiliary vacuum pump 22 to extract gas from the separation tank 1 until the pressure inside the separation tank 1 stabilizes at a preset value. After the poultry lung suction operation is completed, the cleaning mechanism 6 sprays 80°C hot water to clean the separation tank 1, and the ozone generator 4 introduces ozone gas into the separation tank 1 for 30 minutes to sterilize the separation tank 1 and prevent Salmonella from exceeding the standard.

[0033] In the poultry lung suction machine provided by this utility model, the parallel vacuum pump group includes a main vacuum pump 21 and an auxiliary vacuum pump 22. The main vacuum pump 21 and the auxiliary vacuum pump 22 are connected in parallel and are both connected to the separation tank 1 through a vacuum tube 23. A pressure difference sensor 33 is installed in the suction tube 31 of the lung suction mechanism to detect the pressure difference between the suction tube 31 opening and the target lung. A pressure sensor 11 is installed in the separation tank 1 to detect the internal pressure. When fluctuations or decreases are detected in the internal pressure of the separation tank 1 and the pressure difference between the suction tube 31 opening and the target lung, the control mechanism 5 controls the auxiliary vacuum pump 22 to extract gas from the separation tank 1 for pressure compensation, maintaining a stable negative pressure inside the separation tank 1. In addition, ozone gas is introduced into the separation tank 1 by setting an ozone generator 4 to sterilize the separation tank 1 and effectively prevent Salmonella contamination.
