Description

Technical Field

[0001] The present application relates to the technical field of automatic milking parlor cleaning systems, and in particular to a pipeline cleaning monitoring device. Background Art

[0002] In recent years, with the increase in the value of domestic dairy brands, the quality requirements of raw milk by dairy processing plants have also been continuously improved. High-quality raw milk should not only have standard milk nutrients, but also have the characteristics of low total bacteria count, low somatic cell count, no antibiotics, impurities, and no water.

[0003] In order to effectively reduce the total number of bacteria in milk, the cleaning pipes in the milking parlor need to be cleaned regularly. In the industrial automated cleaning system of the milking parlor process, the traditional cleaning monitoring device is generally set on the straight section of the cleaning pipe to perform liquid transmission and data monitoring on the fluid in the cleaning pipe. However, the straight pipe design easily generates bubbles inside the pipe, which interferes with the measurement of the data acquisition instrument and leads to inaccurate measurement results, especially when monitoring the concentration of the cleaning medium; this inaccurate measurement will have a negative impact on the cleaning effect of the pipe, and thus affect the efficiency and quality of the entire industrial process. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present application provides a pipeline cleaning monitoring device.

[0005] The present application provides a pipeline cleaning monitoring device that adopts the following technical solution:

[0007] By adopting the above-mentioned technical scheme, during the process of data monitoring of the liquid in the cleaning pipe by the cleaning monitoring device in the present application, a pipe structure including a thinner pipe above and a sinking pipe is formed between the sinking pipe and the inlet pipe section, the gas exhaust pipe and the exhaust pipe section. The liquid in the cleaning pipe can pass into the measuring pipe group through the inlet pipe section, and settle and flow down to the sinking pipe under the action of gravity and the flow of the fluid itself. The bubbles in the cleaning pipe are discharged from the thinner gas exhaust pipe above due to buoyancy and other reasons, thereby keeping the liquid in the sinking pipe full, avoiding the interference of bubbles on the data collected by the monitoring instrument, and effectively improving the accuracy of the measurement data.

[0008] Preferably, the discharge pipe section is connected with a flow rate switch for judging whether the measurement data of the monitoring instrument is valid, and the flow rate switch is electrically connected with a PLC control system, and the PLC control system is electrically connected with the monitoring instrument.

[0009] By adopting the above-mentioned technical solution, during the process of data monitoring of the liquid in the cleaning pipeline by the cleaning monitoring device in the present application, the flow rate switch can measure the liquid flow rate in the discharge pipe section and output a signal to the PLC control system to determine whether the data measured at the monitoring instrument is valid.

[0010] Preferably, the sinking pipeline includes an introduction section, a monitoring section and an outlet section which are connected in sequence, the end of the introduction section away from the monitoring section is connected to the inlet pipe section, the end of the outlet section away from the monitoring section is connected to the discharge pipe section, and the inlet pipe section, gas discharge pipeline, discharge pipe section and monitoring section are all arranged horizontally.

[0011] The adoption of the above technical solution is conducive to achieving the sedimentation and stabilization of the liquid, ensuring that the liquid fills the monitoring section and avoiding the influence of bubbles on the monitoring instrument.

[0012] Preferably, the introduction section is perpendicular to the inlet pipe section.

[0014] Preferably, the diameters of the inlet pipe section, the outlet pipe section and the sinking pipe are consistent, and the inlet section is connected to the inlet pipe section via a short tee pipe of equal diameter.

[0015] The adoption of the above technical solution is helpful to reduce the difference between the monitoring pipe group and the cleaning pipe, thereby ensuring the accuracy of the measurement data.

[0016] Preferably, the diameter of the inlet pipe section is larger than the diameter of the gas exhaust pipe, and the diameter of one end of the inlet pipe section close to the gas exhaust pipe gradually decreases from the inside to the outside.

[0017] By adopting the above technical solution, as the diameter of the incoming pipe section gradually becomes smaller, the resistance encountered by the liquid when flowing toward the gas discharge pipe gradually increases, which is conducive to making it easier for the liquid in the incoming pipe to flow to the sinking pipe.

[0018] Preferably, the diameter of the discharge pipe section is larger than the diameter of the gas discharge pipeline, and the diameter of one end of the discharge pipe section close to the gas discharge pipeline gradually decreases from inside to outside.

[0019] By adopting the above technical solution, the resistance encountered by the gas when it flows from the gas exhaust pipeline to the exhaust pipe section is gradually reduced, thereby facilitating the discharge of the gas in the gas exhaust pipeline.

[0020] Preferably, the inlet pipe section, the gas exhaust pipe and the exhaust pipe section are coaxially arranged.

[0021] By adopting the above technical solution, it is easy to realize the flow of bubbles in the liquid from the inlet pipe section to the gas exhaust pipe and the exhaust pipe section.

[0022] Preferably, the introduction section and the monitoring section as well as the outlet section and the monitoring section are connected via elbows.

[0023] By adopting the above technical solution, it is convenient to reduce the resistance to liquid flow caused by the cross-section between the pipe walls, so that the liquid can fill the sinking pipe more easily.

[0024] Preferably, the length of the gas exhaust pipeline is shorter than the length of the monitoring section.

[0025] By adopting the above technical solution, it is easy to discharge the bubbles from the gas discharge pipe, thus avoiding the accumulation of bubbles in the measuring tube group.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. With the help of the bubble discharge pipe and the sinking pipe, the bubbles in the liquid can be effectively discharged from the thinner pipe at the upper end, so as to achieve the sedimentation and stability of the liquid, and make the liquid fill the sinking pipe, thereby ensuring the stability of the measurement data;

[0028] 2. This device avoids the deviation of key cleaning data such as cleaning medium concentration collected by digital acquisition instruments due to the presence of bubbles in the pipeline, and improves the standardization of pipe fittings and the modularization level of data monitoring.

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The embodiment of the present application discloses a pipeline cleaning monitoring device.

[0035] Reference Figure 1 A pipeline cleaning monitoring device includes a monitoring instrument 1 and a measuring pipe group connected to the cleaning pipeline, the measuring pipe group includes an inlet pipe section 2, a gas exhaust pipe 3, a discharge pipe section 4 and a sinking pipe 5, the inlet pipe section 2, the gas exhaust pipe 3 and the discharge pipe section 4 are connected in sequence, the sinking pipe 5 is located below the inlet pipe section 2, the gas exhaust pipe 3 and the discharge pipe section 4, and the two ends of the sinking pipe 5 are respectively connected to the inlet pipe section 2 and the discharge pipe section 4, the diameter of the gas exhaust pipe 3 is smaller than the diameter of the sinking pipe 5, and the monitoring instrument 1 is installed on the sinking pipe 5; further, the discharge pipe section 4 is connected with a flow rate switch 6 for judging whether the measurement data of the monitoring instrument 1 is valid, the flow rate switch 6 is electrically connected to a PLC control system, the PLC control system is electrically connected to the monitoring instrument 1, and the flow rate switch 6 is located at the rear end of the connection between the sinking pipe 5 and the discharge pipe section 4.

[0036] In the process of using the cleaning monitoring device of the present application to monitor the data of the liquid in the cleaning pipeline, the liquid in the cleaning pipeline can be passed into the measuring tube group through the inlet pipe section 2 and flow out of the measuring tube group through the outlet pipe section 4. The flow rate switch 6 measures the flow rate of the liquid in the outlet pipe section 4 at the rear end of the measuring tube group. When the flow rate of the liquid in the outlet pipe section 4 is greater than the specified measurement value, the flow rate switch 6 outputs a signal to the PLC control system, and the PLC control system starts to collect data at the monitoring instrument 1; when the flow rate of the liquid in the outlet pipe section 4 does not reach the specified measurement value, it proves that the cleaning liquid in the cleaning pipeline does not flow effectively and the cleaning is invalid.

[0037] Specifically, refer to Figure 1 and Figure 2 In the embodiment of the present application, the sinking pipeline 5 includes an inlet section 51, a monitoring section 52 and an outlet section 53 which are connected in sequence, and the inlet pipe section 2, the gas exhaust pipe 3, the exhaust pipe section 4 and the monitoring section 52 are all arranged horizontally.

[0038] One end of the inlet section 51 away from the monitoring section 52 is connected to the incoming pipe section 2 through a short equal-diameter tee pipe 7, and one end of the outgoing pipe section 53 away from the monitoring section 52 is connected to the discharge pipe section 4 through a short equal-diameter tee pipe 7. The pipe diameters of the incoming pipe section 2, the discharge pipe section 4, the inlet section 51, the monitoring section 52 and the outgoing pipe section 53 are all consistent, and the pipe diameter of the incoming pipe section 2 is also larger than the pipe diameter of the gas discharge pipe 3. A pipeline structure including a thinner upper pipe and a sinking pipe 5 is formed between the sinking pipe 5 and the incoming pipe section 2, the gas discharge pipe 3 and the discharge pipe section 4.

[0039] In the process of data monitoring of the liquid in the cleaning pipe, the liquid in the cleaning pipe can be passed into the measuring pipe group through the inlet pipe section 2, and settle and flow down to the sinking pipe 5 under the action of gravity and the flow of the fluid itself. The bubbles in the cleaning pipe are discharged from the thinner gas exhaust pipe 3 above due to buoyancy and other reasons, so that the liquid in the sinking pipe 5 remains full, avoiding the interference of bubbles in the data collection of the monitoring instrument 1.

[0040] Further, see Figure 1 and Figure 2 In the embodiment of the present application, the diameter of one end of the incoming pipe section 2 close to the gas exhaust pipe 3 gradually decreases from the inside to the outside. As the diameter of the incoming pipe section 2 gradually decreases, the resistance encountered by the liquid when flowing toward the gas exhaust pipe 3 gradually increases, which is conducive to making it easier for the liquid in the incoming pipe to flow to the sinking pipe 5.

[0041] In a preferred embodiment of the present application, the inlet pipe section 2, the gas exhaust pipe 3 and the exhaust pipe section 4 are coaxially arranged, and the diameter of the gas exhaust pipe 3 is 1 / 2 of the diameter of the inlet pipe section 2, so as to minimize the impact of pipeline diversion and confluence on the flow rate and flow of the liquid subsequently introduced into the exhaust pipe section 4.

[0042] Further, see Figure 1 and Figure 2 In a preferred embodiment of the present application, the outlet section 53 is perpendicular to the discharge pipe section 4, and the inlet section 51 and the monitoring section 52 and the outlet section 53 and the monitoring section 52 are connected by a 90° elbow 8 to reduce the resistance to liquid flow caused by the cross-section between the pipe walls, so that the liquid can more easily flow from the inlet section 51 into and fill the monitoring section 52, and the liquid can easily flow from the monitoring section 52 into the outlet section 53 after data monitoring and collection.

[0043] It should be noted that, refer to Figure 3 In other feasible embodiments of the present application, the inlet section 51 and the inlet pipe section 2 may also be arranged at an acute angle, and the liquid in the inlet pipe section 2 can also settle and flow into the inlet section 51 under the action of gravity and its own flow; the outlet section 53 and the discharge pipe section 4 may also be arranged at an acute angle, and the function of introducing the monitored liquid into the discharge pipe section 4 can also be achieved here, but when the inlet section 51 is perpendicular to the inlet pipe section 2 and the outlet section 53 is perpendicular to the discharge pipe section 4, the liquid in the sinking pipe 5 is more full, and the interference of bubbles on the data collected by the monitoring instrument 1 is relatively minimal.

[0044] Further, see Figure 1 and Figure 2In order to facilitate the discharge of bubbles from the gas discharge pipe 3 and avoid the accumulation of bubbles in the measuring tube group, the length of the gas discharge pipe 3 is shorter than the length of the monitoring section 52, and the diameter of the end of the discharge pipe section 4 close to the gas discharge pipe 3 is gradually increased from the gas discharge pipe 3 to the discharge pipe section 4; when the gas in the gas discharge pipe 3 flows from the gas discharge pipe 3 to the discharge pipe section 4, the resistance encountered by the gas is gradually reduced, and the discharge of the gas in the gas discharge pipe 3 is easier.

[0045] The implementation principle of a pipeline cleaning monitoring device in an embodiment of the present application is as follows: during the process of data monitoring of the liquid in the cleaning pipeline, the pipeline cleaning monitoring device in the present application forms a pipeline structure including a thinner pipeline above and a sinking pipeline 5 through the sinking pipeline 5, the entry pipe section 2, the gas exhaust pipeline 3 and the exhaust pipe section 4. The liquid in the cleaning pipeline can be passed into the measuring pipe group through the entry pipe section 2, and settle and flow down to the sinking pipeline 5 under the action of gravity and the flow of the fluid itself. The bubbles in the cleaning pipeline are discharged from the thinner gas exhaust pipeline 3 above due to buoyancy and other reasons, so that the liquid in the sinking pipeline 5 remains full, effectively reducing the interference of bubbles on the data collected by the monitoring instrument 1, reducing the deviation of key cleaning data such as the cleaning medium concentration collected by the digital acquisition instrument due to the presence of bubbles in the pipeline, improving the accuracy of the measurement data, and improving the standardization of pipe fittings and the modularization level of data monitoring.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
