[0015] The present invention provides a container support device comprising: a bracket, a weighing device, and a lifting component. The bracket has a designated container placement position. The weighing device is mounted on the bracket and is capable of weighing the container. The lifting component is vertically detachable on the bracket, and has a lifting position and a lowering position. When the lifting component is in the lifting position, it lifts one side of the container, causing it to tilt. When the lifting component is in the lowering position, it avoids contact with the container. Thus, when the container is placed in the designated container placement position on the bracket, the weighing device weighs the container. When the weight of the liquid material inside the container is less than a preset value, the lifting component is activated to switch to the lifting position, allowing the container to tilt and collect the remaining liquid material on the bottom wall of the container to one side for easy discharge. By lifting one side of the container tank with a lifting component, the amount of liquid material remaining in the tank can be reduced. Furthermore, since the lifting distance of the lifting component is fixed, the tilt angle of the container tank can be fixed, allowing for more precise dispensing of liquid material each time, thus improving the accuracy of liquid material addition. Additionally, when the weight of the liquid material in the container tank exceeds a preset value, the lifting component is in a lowered position to reduce the gravitational force exerted on it by the heavier container tank, thereby increasing the service life of the lifting component and reducing processing costs. Therefore, the technical solution of this application effectively solves the problem in related technologies where manually emptying the container of liquid material can easily lead to low accuracy in liquid material addition.

[0033] In the present embodiment, as shown in Figure 1 The receiving barrel supporting device includes a support 10, a weighing device 20, and a lifting piece 30. The support 10 is provided with a receiving barrel placing position. The weighing device 20 is arranged on the support 10, and the weighing device 20 can weigh the receiving barrel 40. The lifting piece 30 is arranged on the support 10 in a lifting manner, and the lifting piece 30 is lifted to have a jacking position and a descending position. When the lifting piece 30 is in the jacking position, the lifting piece 30 jacks one side of the receiving barrel 40 to make the receiving barrel 40 be placed obliquely. When the lifting piece 30 is in the descending position, the lifting piece 30 is in avoiding cooperation with the receiving barrel 40.

[0034] In this way, the receiving barrel 40 is placed on the receiving barrel placing position of the support 10, and the weighing device 20 weighs the receiving barrel 40. When the weight of the liquid raw material in the receiving barrel 40 is less than a preset value, the lifting piece 30 can be driven to switch to the jacking position, so that the receiving barrel 40 can be inclined, and the remaining liquid raw material on the bottom wall of the receiving barrel 40 is collected to one side of the receiving barrel 40, so as to facilitate the discharge of the liquid raw material. By jacking one side of the receiving barrel 40 through the lifting piece 30, the amount of the remaining liquid raw material in the receiving barrel 40 can be reduced, and since the lifting distance of the lifting piece 30 is fixed, the inclination angle of the receiving barrel 40 can be fixed, so that the amount of the liquid raw material discharged each time in the receiving barrel 40 is more accurate, thereby improving the adding accuracy of the liquid raw material. When the weight of the liquid raw material in the receiving barrel 40 is greater than the preset value, the lifting piece 30 is in the descending position, so as to reduce the gravity applied by the receiving barrel 40 with heavy weight to the lifting piece 30, thereby improving the service life of the lifting piece 30 and reducing the processing cost. Therefore, the technical scheme of the present embodiment effectively solves the problem in the related art that the liquid raw material in the receiving barrel is poured by manpower, which easily causes the adding accuracy of the liquid raw material to be low.

[0035] In the embodiment, one side of the bottom of the containing barrel 40 is provided with a liquid discharge port, and the lifting member 30 lifts the containing barrel 40 away from the side of the liquid discharge port. The containing barrel 40 is in communication with the mixer through the conveying pipeline 50. When the weight of the liquid raw material in the containing barrel 40 is less than 50 kg, the lifting member 30 is switched to the lifting position. When the lifting member 30 is in the lifting position, the inclination angle of the containing barrel 40 is 20° to 30°. The lifting member 30 is a lifting cylinder.

[0036] In other embodiments, the containing barrel supporting device is arranged above the feeding port of the mixer, and the liquid raw material in the containing barrel 40 can directly flow into the mixer.

[0037] As shown in Figure 1 , the containing barrel supporting device further comprises a controller, the weighing device 20 is signal connected with the controller, and the controller is control connected with the lifting member 30. The signal connection of the controller with the weighing device 20 and the lifting member 30 can monitor the weight of the liquid raw material in the containing barrel 40 in real time. When the weight of the liquid raw material in the containing barrel 40 decreases to a preset value, the controller automatically controls the lifting member 30 to switch to the lifting position, so that the containing barrel 40 is inclined, thereby ensuring the accurate control of the amount of liquid raw material added each time and improving the automation level and the adding precision of the adding process.

[0038] As shown in Figure 1 , the support 10 comprises a support frame 11 and a plurality of supporting legs 12 arranged below the support frame 11 in a spaced manner, and the upper surface of the support frame 11 forms a containing barrel placing position. The weighing device 20 is a plurality of, and the plurality of weighing devices 20 are arranged in one-to-one correspondence with the plurality of supporting legs 12. The weighing device 20 is arranged below the supporting leg 12. By arranging the plurality of supporting legs 12 below the support frame 11 and the plurality of weighing devices 20 corresponding to the plurality of supporting legs 12, the uniform support of the containing barrel 40 is realized, which not only enhances the stability of the overall structure, but also improves the accuracy of weighing through the arrangement of the plurality of weighing devices 20. The support 10 comprises a support frame 11 and a mounting rod 13 connected to the support frame 11, the upper surface of the support frame 11 forms a containing barrel placing position, and the lifting member 30 is arranged at one end of the mounting rod 13. At the same time, the design of the mounting rod 13 makes the installation of the lifting member 30 more convenient, and also makes the lifting of the containing barrel 40 by the lifting member 30 in the lifting position more reliable, thereby ensuring the stability and accuracy of the containing barrel 40 during the inclination process.

[0039] In other embodiments, the support frame 10 comprises a support frame 11 and a plurality of legs 12 arranged in a spaced manner below the support frame 11, and the upper surface of the support frame 11 forms a barrel placement position. The weighing device 20 is in a plurality, and the plurality of weighing devices 20 are arranged in a one-to-one correspondence with the plurality of legs 12. The weighing device 20 is arranged below the leg 12. Alternatively, the support frame 10 comprises a support frame 11 and a mounting rod 13 connected to the support frame 11, and the upper surface of the support frame 11 forms a barrel placement position, and the lifting member 30 is arranged at one end of the mounting rod 13.

[0040] In the present embodiment, the barrel support device further comprises an alarm member, and the alarm member is signal connected with the weighing device 20. In this way, when the weight of the liquid raw material in the barrel 40 drops to an alarm value, the weighing device 20 sends a signal to the alarm member, prompting the operator that the liquid raw material in the barrel 40 is insufficient at this time, and the barrel 40 needs to be replaced or the liquid raw material needs to be added to the barrel 40.

[0041] As shown in Figures 2 to 4 The present application also provides a liquid conveying device, which comprises a barrel 40, a conveying pipeline 50 in communication with the barrel 40, and a barrel support device for supporting the barrel 40, and the barrel support device is the barrel support device described above. Since the barrel support device described above can solve the problem in the related art that the liquid raw material in the barrel is poured by manpower, which easily leads to low precision of adding liquid raw material, the liquid conveying device with the barrel support device can solve the same technical problem. Moreover, the arrangement of the conveying pipeline 50 facilitates the communication between the barrel 40 and the mixer.

[0042] As shown in Figures 2 to 4 The barrel 40 is in a plurality, and the plurality of barrels 40 are replaceably placed on the barrel placement position of the barrel support device. The replaceable design of the barrel 40 enables the production line to adapt to barrels 40 of different specifications, thereby improving the adaptability and flexibility of the production line. The liquid conveying device further comprises a mass flow meter 61 arranged on the conveying pipeline 50. The arrangement of the mass flow meter 61 provides a more accurate means for measuring the liquid raw material, so that the amount of liquid raw material added is more accurate.

[0043] In the present embodiment, after receiving the prompt of the alarm member, the operator can control the lifting member 30 to switch from the jacking position to the descending position by operating the controller, so that the barrel 40 can be placed flat, facilitating the replacement operation of the barrel 40.

[0044] In other embodiments, the barrel 40 is in a plurality, and the plurality of barrels 40 are replaceably placed on the barrel placement position of the barrel support device. Alternatively, the liquid conveying device further comprises a mass flow meter 61 arranged on the conveying pipeline 50.

[0045] As shown in Figures 2 to 4 The liquid delivery device further comprises a connecting hose 62 and a pipe joint 63. The connecting hose 62 is connected between the delivery pipeline 50 and the containing barrel 40, and the connecting hose 62 can be connected to the containing barrel 40 through the pipe joint 63. Through the arrangement of the connecting hose 62 and the pipe joint 63, not only the convenient connection between the delivery pipeline 50 and the containing barrel 40 is ensured, but also the barrel replacement operation is simplified, and the operation convenience and maintenance efficiency of the production line are improved.

[0046] In the embodiment, when the delivery pipeline 50 needs to be cleaned, the pipe joint 63 can be connected to the cleaning pipeline 81. The liquid delivery device further comprises a first proximity switch arranged at the cleaning pipeline 81, which can detect whether the pipe joint 63 is connected to the cleaning pipeline 81. When the delivery pipeline 50 needs to be primed, the pipe joint 63 can be connected to the priming pipeline 82. The liquid delivery device further comprises a second proximity switch arranged at the priming pipeline 82, which can detect whether the pipe joint 63 is connected to the priming pipeline 82.

[0047] As shown in Figures 2 to 4 The liquid delivery device further comprises a heat exchange sleeve 71 arranged outside the delivery pipeline 50, a liquid inlet valve 72 arranged on the heat exchange sleeve 71, and a liquid return valve 73 arranged on the heat exchange sleeve 71. The outer side wall of the delivery pipeline 50 and the inner side wall of the heat exchange sleeve 71 form a heat exchange liquid passage. The arrangement of the heat exchange sleeve 71 provides the delivery pipeline 50 with a temperature control function. Especially when processing liquid raw materials with high viscosity, heating can significantly improve the flowability of the raw materials, reduce the delivery resistance, and improve the addition efficiency and addition accuracy. For example, increasing the temperature of the galacto-oligosaccharide liquid can improve its flowability. The arrangement of the liquid inlet valve 72 and the liquid return valve 73 can facilitate the control of the flow of the heat exchange liquid in the heat exchange liquid passage.

[0048] As shown in Figures 2 to 4 The liquid delivery device further comprises a rotor pump 64 and a mass flow meter 61, both of which are arranged on the delivery pipeline 50, and the rotor pump 64 is located upstream of the mass flow meter 61. The cooperation of the rotor pump 64 and the mass flow meter 61 can not only improve the addition accuracy of the liquid raw materials, but also provide stable delivery pressure, ensuring accurate and rapid delivery of the liquid raw materials while reducing material loss during delivery. Arranging the rotor pump 64 upstream of the mass flow meter 61 makes the flow at the mass flow meter 61 more controllable.

[0049] As shown in Figures 2 to 4As shown, the liquid delivery equipment also includes a branch pipe 74 and a bypass valve 75 installed on the branch pipe 74. One end of the branch pipe 74 is connected to the delivery pipe 50 and located upstream of the rotor pump 64, while the other end of the branch pipe 74 is connected to the delivery pipe 50 and located downstream of the rotor pump 64. The bypass valve 75 allows the liquid delivery system to release pressure when the pressure in the delivery pipe 50 is too high, reducing damage to the delivery pipe 50 and the pump, and improving the safety and stability of the liquid delivery system. The liquid delivery equipment also includes a pressure sensor 76 installed on the delivery pipe 50, located between the rotor pump 64 and the mass flow meter 61. The addition of the pressure sensor 76 allows for real-time monitoring of pressure changes within the delivery pipe 50 during the delivery process, enabling more precise pressure management. This arrangement, with both the bypass valve 75 and the pressure sensor 76 located upstream of the mass flow meter 61, allows for better detection and management of the pressure upstream of the mass flow meter 61, thus extending the service life of the mass flow meter 61.

[0050] In other embodiments, the liquid delivery device further includes a branch line 74 and a bypass valve 75 disposed on the branch line 74. One end of the branch line 74 is connected to the delivery line 50 and located upstream of the rotor pump 64, and the other end of the branch line 74 is connected to the delivery line 50 and located downstream of the rotor pump 64. Alternatively, the liquid delivery device further includes a pressure sensor 76 disposed on the delivery line 50, located between the rotor pump 64 and the mass flow meter 61.

[0051] like Figures 2 to 4 As shown, the liquid conveying equipment also includes a supplementary balloon valve 77 installed on the conveying pipeline 50. The supplementary balloon valve 77 is located downstream of the mass flow meter 61 and has an air inlet that connects to the air path. The supplementary balloon valve 77 allows for the introduction of gas to balance the pressure in the conveying pipeline 50, ensuring that the measurement accuracy of the mass flow meter 61 is not affected at low liquid levels. It also helps to completely drain any residual liquid material in the conveying pipeline 50, further reducing liquid material waste. The liquid conveying equipment also includes a multi-hole butterfly valve 78 installed on the conveying pipeline 50, downstream of the mass flow meter 61. The multi-hole butterfly valve 78 allows for precise addition of liquid material at a smaller flow rate in the final stage of the addition process, further improving the accuracy of liquid material addition and ensuring that the amount of liquid material added to the mixer remains consistent each time.

[0052] In other embodiments, the liquid conveying device further includes a supplementary balloon valve 77 disposed on the conveying pipeline 50, the supplementary balloon valve 77 being located downstream of the mass flow meter 61, and the supplementary balloon valve 77 having an air inlet that can communicate with an air passage. Alternatively, the liquid conveying device further includes a multi-hole butterfly valve 78 disposed on the conveying pipeline 50, the multi-hole butterfly valve 78 being located downstream of the mass flow meter 61.

[0053] The inventor finds that in the prior art, when the liquid galacto-oligosaccharide is added to the mixer, the manual adding mode is usually adopted. Moreover, since the specifications of the liquid galacto-oligosaccharide are various, including 25 kg, 30 kg or 35 kg per bag, the system cannot record the specific weight of each addition, and the manual adding mode is complicated to operate, and the operator is prone to remember the addition amount of the liquid galacto-oligosaccharide each time. When a certain amount of liquid galacto-oligosaccharide is added, the number of times of opening the cover is large when a barrel of liquid galacto-oligosaccharide with a small capacity is used, so that the probability of plastic foreign matter entering the mixer is increased. Moreover, there is a problem of residue in the barrel when manually adding, so that the amount of liquid galacto-oligosaccharide added each time is inaccurate.

[0054] By applying the technical scheme of the embodiment, the containing barrel 40 containing the liquid galacto-oligosaccharide is placed on the containing barrel supporting device, and the side of the containing barrel 40 is lifted up by the lifting piece 30, so that the containing barrel 40 can be inclined by a fixed angle each time, thereby reducing the residue of the liquid galacto-oligosaccharide in the barrel, improving the accuracy of the addition of the liquid galacto-oligosaccharide, reducing the labor intensity and saving the production cost. By replacing the containing barrel 40 containing the liquid galacto-oligosaccharide, the liquid galacto-oligosaccharide is supplied.

[0055] In the embodiment, the capacity of the containing barrel 40 is 1000 kg, by adopting the containing barrel 40 with large capacity, the number of times of opening the cover is reduced, and the risk of plastic foreign matter entering the mixer is reduced. Moreover, the containing barrel 40 with large capacity can be recycled, further reducing the production cost. The weighing device 20 can weigh the weight of the containing barrel 40, and by recording the weight measured by the weighing device 20, a liquid raw material addition data curve is drawn, so that the addition amount of the liquid raw material can be traced.
