[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example

[0032] Please see Figures 1-6 The present invention provides the following technical solution: a precision fluid quantitative conveying device, including a conveying pipe 1, wherein an inlet pipe 2 and an outlet pipe 3 are respectively connected to both sides of the outer wall of the conveying pipe 1;

[0033] Sealing plates 4 are fixedly installed at both ends of the conveying pipe 1;

[0034] The delivery pipe 1 is equipped with a metering component 100 for precise control and metering of fluid. The metering component 100 includes a connecting pipe 101 rotatably connected to two sealing plates 4.

[0035] A pressure sensor 102 is installed inside the connecting pipe 101;

[0036] Multiple baffles 103 are fixedly provided at even intervals around the outer wall of the connecting pipe 101;

[0037] A motor 104 is fixedly mounted on one of the sealing plates 4, and the output shaft of the motor 104 is coaxially connected to the connecting pipe 101. In use, a pressure sensor 102 is connected to the motor 104 control module. Multiple baffles 103 spaced apart on the outer wall of the connecting pipe 101 create multiple fluid chambers. When fluid enters the delivery pipe 1, it falls into one of the fluid chambers. Simultaneously, the pressure sensor 102 detects the pressure within the fluid chamber and transmits the pressure data to the motor 104 control module. When the pressure within the fluid chamber reaches a preset value, the motor 104... The 04 control module starts the motor 104, which drives the connecting pipe 101 to rotate. This causes the fluid chamber, which has reached the preset pressure, to rotate to the side of the discharge pipe 3. At this time, the fluid chamber is connected to the discharge pipe 3, and the fluid in the fluid chamber is discharged through the discharge pipe 3, realizing the quantitative delivery of the fluid. At the same time, another fluid chamber rotates to the side of the inlet pipe 2 and is connected to the inlet pipe 2, ready to receive new fluid. This cycle can realize the continuous quantitative delivery of fluid, making the delivery of fluid more accurate, avoiding the problems of waste or insufficient fluid volume, and improving the efficiency of fluid use.

[0038] Preferably, by Figure 1 and Figure 4 As shown in this embodiment, one of the sealing plates 4 is provided with multiple observation windows 5; through the observation windows 5, the condition of the fluid inside the delivery pipe 1 can be observed intuitively, including the flow state of the fluid, the filling status of the fluid chamber, etc., so as to facilitate the staff to monitor the operating status of the equipment.

[0039] Preferably, by Figure 2 and Figure 5 As shown, in this embodiment, each of the multiple baffles 103 is provided with a pair of connecting plates 105, and adjacent baffles 103 are connected to each other through the connecting plates 105. The setting of the connecting plates 105 increases the structural strength between the baffles 103, making the connecting pipe 101 more stable during rotation, avoiding the problem of deformation or damage to the baffles 103 caused by fluid pressure or vibration generated by rotation, and improving the durability and reliability of the equipment. At the same time, the setting of the connecting plates 105 also helps to maintain the consistency of the shape and size of the fluid chamber.

[0040] Preferably, by Figure 1 , Figure 3 and Figure 6 As shown, in this embodiment, a water pipe 7 is installed on the outer wall of the conveying pipe 1 near the feed pipe 2;

[0041] The water pipe 7 extends axially along the delivery pipe 1, and multiple high-pressure nozzles 8 are spaced apart on the water pipe 7;

[0042] A rectangular hole 6 is provided on the outer wall of the conveying pipe 1 in the area corresponding to the water pipe 7. When the fluid chamber needs to be cleaned, the cleaning fluid can be delivered to the high-pressure nozzle 8 through the water pipe 7. The high-pressure nozzle 8 sprays the cleaning fluid out at high pressure. The cleaning fluid enters the interior of the conveying pipe 1 through the rectangular hole 6 to clean the fluid chamber, effectively avoiding the pollution problem caused by fluid residue, improving the cleanliness of the equipment and the purity of the fluid delivery. Moreover, by placing the rectangular hole 6 close to the feed pipe 2, the fluid can be prevented from flowing out of the rectangular hole 6 during fluid delivery, ensuring the normal delivery of the fluid.

[0043] Preferably, by Figure 4 and Figure 6 As shown, in this embodiment, a sealing shell 9 is also installed on the outer wall of the conveying pipe 1. The sealing shell 9 covers the rectangular hole 6, and the size of the sealing shell 9 is larger than the size of the rectangular hole 6. The sealing shell 9 can further prevent fluid from leaking from the rectangular hole 6, and at the same time protect the high-pressure nozzle 8 from interference and damage from the external environment, thereby improving the overall sealing performance and safety of the equipment. When the equipment is running, the sealing shell 9 can effectively isolate external dust, moisture and other impurities from entering the interior of the conveying pipe 1, ensuring the purity of the fluid conveying and the stable operation of the equipment.

[0044] Components not described in detail in this article are existing technologies.

[0045] The working principle and usage process of this utility model are as follows: In actual use, the fluid is injected into the fluid chamber of the current station (which is surrounded by adjacent baffles 103 and connecting pipes 101) through the feed pipe 2. The pressure sensor 102 monitors the pressure inside the chamber in real time and sends a signal to the control module after reaching the preset value.

[0046] At this time, the start motor 104 drives the connecting pipe 101 to rotate, the full-load chamber is precisely aligned with the discharge pipe 3, and the empty chamber is simultaneously triggered to align with the feed pipe 2. While the fluid in the full-load chamber is being discharged, new fluid has fallen into the empty chamber to wait for the next quantitative delivery. This process ensures the continuity and accuracy of fluid delivery, and significantly improves fluid processing efficiency and ease of operation.

[0047] When the fluid chamber needs to be cleaned, cleaning fluid can be delivered to the high-pressure nozzle 8 through the water pipe 7. The high-pressure nozzle 8 sprays the cleaning fluid out at high pressure. The cleaning fluid enters the delivery pipe 1 through the rectangular hole 6 to clean the fluid chamber, effectively avoiding the pollution problem caused by fluid residue, improving the cleanliness of the equipment and the purity of fluid delivery. Moreover, by setting the rectangular hole 6 close to the feed pipe 2, it can prevent the fluid from flowing out of the rectangular hole 6 during fluid delivery, ensuring the normal delivery of the fluid.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
