Description

Technical Field

[0002] Liquid feeders are widely used in various industrial production processes to accurately deliver liquid materials to the production line. Liquid feeding equipment currently on the market usually adopts a single-design feed port structure, which is difficult to meet the delivery needs of liquids with different viscosities.

[0003] The plugging blocks in the existing feeding system are mostly fixed in design and lack adaptability to the flow characteristics of the liquid. When dealing with high-viscosity liquids, the traditional feed port design usually causes blockage or unstable flow due to excessive resistance; when dealing with low-viscosity liquids, the feed port often leaks and has large flow deviations due to the lack of a reasonable sealing design. In addition, in some production processes that require liquids of different viscosities, stable flow control cannot be achieved due to the lack of a targeted feeding structure. These problems are particularly prominent under the demand for high-precision liquid delivery in modern industry.

[0004] In addition, liquid feeders in the prior art are usually not equipped with effective heating functions, which results in increased flow resistance due to high viscosity when processing high-viscosity liquids, thereby affecting the stability of the feed. This situation not only increases the maintenance frequency of the equipment, but also affects production efficiency. It is difficult for traditional equipment to optimize the flow characteristics of liquids of different viscosities by adjusting the feed structure or temperature, making it difficult for users to flexibly adjust according to the properties of the material in actual production.

DETAILED DESCRIPTION

[0032] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0034] Thus, the present invention relates to a liquid feeding system suitable for conveying liquids of various viscosities. When in use, after the plugging block 10 is installed on the twin-screw extruder, the output end of the gun head 9 is connected to the plugging block 10, and the gun head 9 injects the liquid into the twin-screw extruder through the plugging block 10 to achieve further processing of the liquid. By providing the heating device 6, after the liquid enters the metering bin 21, the stirring component 4 stirs the liquid to ensure that the liquid is evenly mixed in the metering bin 21, avoiding precipitation or stratification of high-viscosity liquids. After being fully stirred in the metering bin 21, the liquid enters the feed conveying pipe 5. The heating device 6 is connected to the feed conveying pipe 5. A temperature sensor can be used to monitor the real-time temperature and automatically adjust the heating power to avoid the influence of too high or too low temperature on the fluidity of the liquid. Then the liquid flows into the gear pump 7. The gear pump 7 pushes the liquid to the downstream evenly through the rotation of two gears. Under the action of the gear pump 7, the liquid is subjected to voltage stabilization treatment, and enters the discharge conveying pipe 8 after the pressure is stabilized. After the liquid passes through the discharge conveying pipe 8, it flows into the gun head 9. The gun head 9 is set at the end of the liquid delivery and is designed to be a detachable structure for easy cleaning and maintenance. The liquid enters the injection block 10 through the gun head 9. The injection block 10, as a key conveying component, ensures that the liquid can accurately and stably enter the screw of the extruder for further processing.

[0035] Optionally, the metering mechanism 2 includes a metering bin 21, a support column 22 and a bottom plate 23, wherein a plurality of support columns 22 are provided, one end of each support column 22 is connected to the metering bin 21, and the bottom plate 23 is connected to the other end of each support column 22.

[0036] Furthermore, a discharge pipe is provided at the bottom of the metering bin 21, and a valve 211 is provided on the discharge pipe. By providing the valve 211, if there is any residual liquid material in the metering bin 21, it can be discharged through the valve 211. In this embodiment, the bottom plate 23 is connected to the base 1 through a weighing sensor, and by providing the weighing sensor, the liquid in the metering bin 21 can be weighed.

[0037] In this embodiment, the stirring assembly 4 includes a stirring motor 41, a stirring shaft 42 and a stirring blade 43. The stirring motor 41 is arranged on the bracket 3. The stirring shaft 42 is connected to the stirring motor 41 and driven to rotate by the stirring motor 41. The stirring blade 43 is arranged on the stirring shaft 42, and the stirring blade 43 is located in the metering bin 21. After the liquid is placed in the metering bin 21, the stirring motor 41 drives the stirring shaft 42 to rotate, and the rotation of the stirring shaft 42 drives the stirring blade 43 to rotate. The stirring blade 43 rotates to achieve uniform stirring of the liquid in the metering bin 21, thereby preventing the precipitation or stratification of the high-viscosity liquid.

[0038] Preferably, the heating device 6 is connected to a temperature sensor. The prior art liquid feeder is usually not equipped with an effective heating function, which results in increased flow resistance due to high viscosity when processing high viscosity liquids, thereby affecting the stability of the feed, which not only increases the maintenance frequency of the equipment, but also affects the production efficiency.

[0039] In this regard, the present invention provides a heating device 6, and the heating device 6 is connected to a temperature sensor. The heating device 6 can heat the liquid in the feed delivery pipe 5 to control the fluidity of the liquid, so that the liquid can maintain fluidity even under high viscosity conditions, reducing the risk of blockage. The temperature control range of the heating device 6 is adjustable to meet the needs of different viscosities and flow rates, ensuring continuous liquid delivery under various working conditions.

[0040] In summary, in order to solve the problem of transporting high-viscosity or easily crystallized liquids, the present invention designs a heating system that can flexibly heat the liquid in the transport pipeline according to the characteristics of the liquid, prevent the viscosity of the liquid from rising or crystallizing in a low-temperature environment, and ensure the fluidity of the liquid. The system improves the liquid transport efficiency and is suitable for liquid transport processes that need to maintain a stable temperature, especially in the food, chemical and other industries, which have significant advantages.

[0041] Further, a running wheel 11 is provided at the bottom of the base 1, and the liquid feeding system can be conveniently moved as a whole by providing the running wheel 11. Further, a connecting pipe is provided on the gun head 9, and the connecting pipe is connected to the liquid inlet 1021. The liquid inlet 1021 and the connecting pipe can be threadedly connected, so that the gun head 9 is firmly fixed on the injection block 10.

[0042] In this embodiment, the injection block 10 includes a main body, which includes a plug 101 and a connecting plate 102. The plug 101 is arranged on the connecting plate 102. A liquid inlet 1021 is arranged on the connecting plate 102. An installation port 1022 is arranged on the outer side of the connecting plate 102. By setting the connecting plate 102, it is convenient to fix the injection block 10 on the extruder through the installation port 1022.

[0043] like Figure 2 and Figure 3As shown, the plugging block 10 in this embodiment is a high viscosity applicable plugging block 10, and the plug 101 of the high viscosity applicable plugging block 10 includes a first plate 1011, a second plate 1012, a third plate 1013 and a fourth plate 1014, one side of the first plate 1011 is connected to one side of the second plate 1012, the other side of the second plate 1012 is connected to one side of the third plate 1013, the other side of the third plate 1013 is connected to one side of the fourth plate 1014, and the other side of the fourth plate 1014 is connected to the first plate 10 11 On the other side, the high viscosity applicable plugging block 10 is set on the connecting plate 102 and the connecting plate 102 is limited to an outer plate 1023 and an inner plate 1024, the outer plate 1023 is located on the outer side of the high viscosity applicable plugging block 10, the inner plate 1024 is located on the inner side of the high viscosity applicable plugging block 10, a natural exhaust port 10241 is set on the inner plate 1024, the high viscosity applicable plugging block 10 is surrounded to form a groove 103, an inclined surface is set on the second plate body 1012, and a liquid channel 10121 connected to the liquid inlet 1021 is set on the inclined surface.

[0044] The high-viscosity applicable plugging block 10 is equipped with a natural exhaust port 10241 and is suitable for conveying high-viscosity liquids. Air is released through the natural exhaust port 10241 to reduce flow resistance and ensure stable feeding of high-viscosity liquids.

[0045] In order to further prove that the high viscosity applicable plugging block 10 is applicable to high viscosity liquids, the inventors used liquids of different viscosities to enter the metering chamber 21, and the liquid was injected into the high viscosity applicable plugging block 10 from the gun head 9, and finally the flow value was measured.

[0046] Specifically, in Example 1, the inventors injected nylon spinning oil with a concentration of 600 mPa·s into the high-viscosity applicable plugging block 10 and measured the flow value.

[0047] In Example 2, the inventors injected nylon spinning oil with a concentration of 200 mPa·s into the high-viscosity applicable plugging block 10 and measured the flow value.

[0048] In Example 3, the inventors injected pure water with a concentration of 1 mPa·s into the multi-viscosity applicable plugging block 10 and measured the flow value.

[0049] The test results of Examples 1 to 3 are as follows:

[0050]

[0051] It can be seen that the deviation value in Example 1 is smaller than that in Example 2, and the deviation value in Example 1 is smaller than that in Example 3. In Example 1, a nylon spinning oil with a concentration of 600 mPa·s is used. Therefore, the high-viscosity applicable plugging block 10 is suitable for high-viscosity liquids.

[0052] like Figure 4 and Figure 5 As shown, the plugging block 10 in this embodiment is a plugging block 10 suitable for medium viscosity, and the surface of the plug 101 of the plugging block 10 suitable for medium viscosity forms a first arc surface 1015 and a second arc surface 1016. The inside of the plugging block 10 suitable for medium viscosity forms a liquid inlet channel 10161 connected to the liquid inlet 1021, and the output end of the liquid inlet channel 10161 is located on the second arc surface 1016. The plugging block 10 suitable for medium viscosity has no groove structure. After the plugging block 10 suitable for medium viscosity is connected to the extruder, the first arc surface 1015 is located at the periphery of one screw, and the second arc surface 1016 is located at the periphery of the other screw. The plugging block 10 suitable for medium viscosity cooperates closely with the extruder, so it is suitable for medium viscosity liquid, effectively reduces leakage, and ensures flow accuracy.

[0053] In order to further prove that the medium viscosity applicable plugging block 10 is applicable to medium viscosity liquids, the inventors used liquids of different viscosities to enter the metering chamber 21, and the liquids were injected into the medium viscosity applicable plugging block 10 from the gun head 9, and finally the flow value was measured.

[0054] Specifically, in Example 4, the inventors injected nylon spinning oil with a concentration of 600 mPa·s into the medium viscosity applicable plugging block 10 and measured the flow value.

[0055] In Example 5, the inventors injected nylon spinning oil with a concentration of 200 mPa·s into the medium viscosity applicable plugging block 10 and measured the flow value.

[0056] In Example 6, the inventors injected pure water with a concentration of 1 mPa·s into the medium viscosity applicable plugging block 10 and measured the flow value.

[0057] The test results of Examples 4 to 6 are as follows:

[0058]

[0059] It can be seen that the deviation value in Example 4 is greater than the deviation value in Example 5, and the deviation value in Example 5 is less than the deviation value in Example 6. In Example 5, a nylon spinning oil with a concentration of 200 mPa·s is used. Therefore, the medium viscosity injection block 10 is suitable for medium viscosity liquids.

[0060] like Figure 6 and Figure 7As shown, the plugging block 10 in this embodiment is a multi-viscosity plugging block 10, and the plug 101 of the multi-viscosity plugging block 10 includes a first side plate 1017, a front plate 1018, a second side plate 1019 and a rear plate 10110. One side of the first side plate 1017 is connected to one side of the front plate 1018, the other side of the front plate 1018 is connected to one side of the second side plate 1019, the other side of the second side plate 1019 is connected to one side of the rear plate 10110, and the other side of the rear plate 10110 is connected to the other side of the first side plate 1017. , the second side plate 1019 and the bottom of the rear plate 10110 are fixedly connected to the connecting plate 102; the multi-viscosity applicable plugging block 10 is arranged on the connecting plate 102 and the connecting plate 102 is limited to an outer connecting plate 1025 and an inner connecting plate 1026, the outer connecting plate 1025 is located on the outside of the multi-viscosity applicable plugging block 10, and the inner connecting plate 1026 is located on the inside of the multi-viscosity applicable plugging block 10, the inner connecting plate 1026 and the multi-viscosity applicable plugging block 10 jointly form a pressure-stabilizing groove 104, and the inner connecting plate 1026 is provided with a liquid inlet 1021 connected to the pressure-stabilizing groove 104.

[0061] When in use, the multi-viscosity injection block 10 is set on the extruder, and then the gun head 9 is connected to the liquid inlet 1021 of the injection block 10, and the gun head 9 injects the liquid into the extruder through the liquid inlet 1021. Since the inner connecting plate 1026 and the surrounding plate together form the pressure stabilizing groove 104, the inner connecting plate 1026 is provided with the liquid inlet 1021 connected to the pressure stabilizing groove 104. When part of the gas is generated in the extruder during the transportation of liquids of different viscosities, the part of the gas can enter the pressure stabilizing groove 104, and the pressure stabilizing groove 104 can stabilize the air pressure in the screw cavity, thereby realizing relatively stable transportation of liquid flow.

[0062] The liquid inlet 1021 of the multi-viscosity applicable plugging block 10 is biased to the left, suitable for high, medium and low viscosity liquids, and the structural design ensures the stability of the delivery of liquids with different viscosities. This innovative design solves the problem that a single structure in the prior art is difficult to adapt to different liquid viscosities, and improves the versatility of the device.

[0063] Furthermore, the surface of the front plate 1018 forms a first arc portion 10181 and a second arc portion 10182, and the surface of the rear plate 10110 forms a third arc portion 10111 and a fourth arc portion 10112, wherein the third arc portion 10111 is arranged corresponding to the first arc portion 10181, and the fourth arc portion 10112 is arranged corresponding to the second arc portion 10182. The twin-screw extruder has twin screws, and by arranging the first arc portion 10181 and the third arc portion 10111, it is convenient to give way to one of the twin screws, and by arranging the second arc portion 10182 and the fourth arc portion 10112, it is convenient to give way to the other screw in the twin screw, so that the connection between the injection block 10 and the extruder is relatively tight.

[0064] In this embodiment, the outer surfaces of the first side plate 1017, the front plate 1018, the second side plate 1019 and the rear plate 10110 are perpendicular to the surface of the connecting plate 102. In this way, when the injection block 10 is fixed in the extruder, the outer surfaces of the first side plate 1017, the front plate 1018, the second side plate 1019 and the rear plate 10110 are closely attached to the inner wall of the extruder, so that the injection block 10 is tightly connected to the extruder. The inner surface of the second side plate 1019 is provided with an inclined surface, so as to improve the overall strength of the injection block 10.

[0065] In order to further prove that the multi-viscosity applicable plugging block 10 is applicable to liquids of different viscosities, the inventors used liquids of different viscosities to enter the metering chamber 21, and the liquid was injected into the multi-viscosity applicable plugging block 10 from the gun head 9, and finally the flow value was measured.

[0066] Specifically, in Example 7, the inventors injected nylon spinning oil with a concentration of 600 mPa·s into the multi-viscosity applicable plugging block 10 and measured the flow value.

[0067] In Example 8, the inventors injected nylon spinning oil with a concentration of 200 mPa·s into the multi-viscosity applicable plugging block 10 and measured the flow value.

[0068] In Example 9, the inventors injected pure water with a concentration of 1 mPa·s into the multi-viscosity applicable plugging block 10 and measured the flow value.

[0069] The test results of Examples 7 to 9 are as follows:

[0070]

[0071] It can be seen from this that the actual flow rate of the multi-viscosity applicable injection block 10 is slightly different from the theoretical flow rate in the case of liquids with different viscosities. Therefore, the multi-viscosity applicable injection block 10 can be well applied to liquids with different viscosities.

[0072] In summary, the present invention designs three different structures of injection blocks 10 to adapt to the feeding requirements of high viscosity, medium viscosity and low viscosity liquids or multiple viscosities, and provides a highly targeted solution. Through the innovative design of the injection block 10 of the present invention, the user can flexibly adjust the feed port structure according to the viscosity of the liquid to achieve accurate delivery of liquids of different viscosities. By designing different injection blocks 10, including a high viscosity adaptive injection block 10 with a natural exhaust port 10241, a medium viscosity adaptive injection block 10 with a sealed feed port, and a multifunctional injection block 10 suitable for different viscosities, the equipment can flexibly adapt to different production needs and improve the efficiency and stability of liquid delivery. At the same time, the built-in heating device 6 can effectively reduce the flow resistance when processing high viscosity liquids to ensure smooth delivery of the liquid.
