Description

Technical Field

[0001] This utility model belongs to the field of pipe pile technology, and in particular relates to a weighing and mixing device for pipe pile release oil. Background Technology

[0002] Mold release oils are typically formulated using mineral oil (such as waste engine oil or base oil) or vegetable oil as a base, with the addition of specific emulsifiers, film-forming agents, and functional additives to form a stable emulsion. For example, a common formulation mixes 100 kg of waste engine oil with 200-400 kg of water. To improve release performance, the mixing process requires strict control of stirring speed and temperature to ensure complete emulsification of the components. The final product must meet requirements such as pH neutrality (7-8), high stability, and rapid film formation after spraying, to achieve a smooth surface and no mold residue after demolding of the pipe pile. Mold release oil formulation is usually done manually or with rough measurement, which can easily lead to deviations in the proportions of oil, water, emulsifiers, and additives. Due to insufficient metering accuracy and limitations in mixing process control in related technologies, inaccurate oil-to-water ratios are also common. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A weighing and mixing device for release oil for pipe piles includes a mixing tank, a storage tank, a first stirring mechanism, a second stirring mechanism, a control mechanism, an oil outlet branch, an oil inlet branch, a water inlet branch, an oil extraction branch, and a weighing support structure.

[0006] The mixing tank and the storage tank are arranged side by side, and the weighing support structure is located at the bottom of the mixing tank;

[0007] The mixing tank is equipped with the first stirring mechanism, and the storage tank is equipped with the second stirring mechanism;

[0008] The oil inlet branch and the water inlet branch are symmetrically arranged at the top of the mixing tank;

[0009] One end of the oil extraction branch is connected to the bottom of the mixing tank, and the other end of the oil extraction branch is connected to the top of the storage tank.

[0010] The oil outlet branch is located at the bottom of the storage tank;

[0011] Both the first stirring mechanism and the second stirring mechanism are connected to the control mechanism.

[0012] Furthermore, the oil inlet branch includes an oil inlet bend, a first solenoid valve, and a first threaded pipe. One end of the oil inlet bend is connected to the top of the mixing tank, and the other end of the oil inlet bend is connected to the first solenoid valve. The end of the first solenoid valve away from the oil inlet bend is connected to the first threaded pipe.

[0013] Furthermore, the water inlet branch includes a water inlet bend, a second solenoid valve, and a second threaded pipe. One end of the water inlet bend is connected to the top of the mixing tank, and the other end of the water inlet bend is connected to the second solenoid valve. The end of the second solenoid valve away from the water inlet bend is connected to the second threaded pipe.

[0014] Furthermore, the oil extraction branch includes an oil extraction pipe and an oil extraction pump. One end of the oil extraction pipe is connected to the bottom of the mixing tank, and the other end of the oil extraction pipe is connected to the top of the storage tank. The oil extraction pump is mounted on the oil extraction pipe.

[0015] Furthermore, the oil outlet branch includes an oil outlet port, a third solenoid valve, and a third threaded pipe. The third solenoid valve is connected to the bottom of the storage tank through the oil outlet port, and the third threaded pipe is located at the end of the third solenoid valve away from the oil outlet port.

[0016] Furthermore, the weighing support structure includes a triangular support, a triangular base plate, and three weighing sensors. The triangular base plate is disposed on the lower end face of the triangular support, and the three weighing sensors are distributed in a triangle and installed at the three vertices of the triangular support. The three weighing sensors are located at the bottom of the mixing tank.

[0017] Furthermore, the first stirring mechanism includes a first servo motor, a first drive sleeve, a first rotating rod, a first helical blade assembly, and multiple stirring frames. The first drive sleeve is disposed on the top of the rotating rod, and the top of the rotating rod is rotatably engaged with the mixing tank. The first helical blade assembly is disposed on the first rotating rod, and the multiple stirring frames are evenly distributed circumferentially on the first rotating rod.

[0018] Furthermore, the second stirring mechanism includes a second servo motor, a second drive sleeve, a second rotating rod, a second spiral blade assembly, and eight stirring blades. The second drive sleeve is disposed on the top of the rotating rod, and the top of the rotating rod is rotatably engaged with the mixing tank. The second spiral blade assembly is disposed on the second rotating rod, and four stirring blades are circumferentially distributed on the lower part of the second rotating rod and on the upper part of the second rotating rod.

[0019] Compared with the prior art, the weighing and mixing device for release oil of pipe piles described in this utility model has the following advantages:

[0020] 1. The weighing support structure adopts a triangular sensor layout to achieve high-precision dynamic metering of oil, water, and additive input by monitoring the overall mass change of the mixing tank in real time. This avoids the metering distortion caused by medium viscosity and air bubbles in traditional level gauges or flow meters, ensuring that the formula ratio strictly matches the process requirements and eliminating the risk of emulsion stratification caused by inaccurate proportioning at the source.

[0021] 2. The first and second stirring mechanisms can simultaneously achieve high-shear emulsification and axial circulation, quickly breaking the interfacial tension between oil and water; the layered blade design of the storage tank maintains emulsion homogeneity through upper and lower double-layer stirring, preventing solid particles from settling. The two mechanisms are independently controlled to adapt to the mixing needs at different stages—the former strongly disturbs to form a stable emulsion, while the latter weakly disturbs to maintain storage stability, jointly solving the pain point of traditional single stirring mode being unable to balance initial mixing efficiency and long-term storage.

[0022] 3. The dual-tank physical isolation design decouples mixing and storage functions: the mixing tank focuses on precise ingredient dosing and initial emulsification, while the storage tank handles maturation and temporary storage. This ensures that the mixing process is not disturbed by discharge (such as liquid level fluctuations affecting weighing accuracy) and avoids damage to the emulsified system caused by frequent start-ups and stops of agitation. An oil extraction branch connects the two tanks, enabling closed-loop transfer, minimizing external contamination, and providing an independent space for the maturation of release agents (such as full hydration of polymers), significantly improving batch consistency.

The oil outlet branch 210 is located at the bottom of the storage tank 200. Both the first stirring mechanism and the second stirring mechanism are connected to the control mechanism.

[0035] The dual-tank physical isolation design decouples the mixing and storage functions: mixing tank 100 focuses on precise batching and initial emulsification, while storage tank 200 handles maturation and temporary storage. This ensures that the mixing process is not disturbed by discharge (such as liquid level fluctuations affecting weighing accuracy) and avoids damage to the emulsified system caused by frequent start-ups and stops of agitation. An oil extraction branch 600 connects the two tanks, enabling closed-loop transfer, minimizing external contamination, and providing an independent space for the maturation of release agents (such as full hydration of polymers), significantly improving batch consistency.

[0036] The oil inlet branch 300 includes an oil inlet bend, a first solenoid valve, and a first threaded pipe. One end of the oil inlet bend is connected to the top of the mixing tank 100, and the other end is connected to the first solenoid valve. The end of the first solenoid valve away from the oil inlet bend is connected to the first threaded pipe.

One end of the oil extraction pipe is connected to the bottom of the mixing tank 100, and the other end is connected to the top of the storage tank 200. The oil extraction pump 610 is mounted on the oil extraction pipe. The oil outlet branch 210 includes an oil outlet port, a third solenoid valve, and a third threaded pipe. The third solenoid valve is connected to the bottom of the storage tank 200 through the oil outlet port, and the third threaded pipe is located at the end of the third solenoid valve away from the oil outlet port.

[0037] The weighing support structure includes a triangular support 720, a triangular base plate 710, and three weighing sensors 730. The triangular base plate 710 is located on the lower end face of the triangular support 720. The three weighing sensors 730 are arranged in a triangle and installed at the three vertices of the triangular support 720. The three weighing sensors 730 are located at the bottom of the mixing tank 100. This triangular sensor layout allows for high-precision dynamic metering of the amount of oil, water, and additives added by real-time monitoring of the overall mass change of the mixing tank 100. This avoids the metering distortion caused by medium viscosity and air bubbles in traditional level gauges or flow meters, ensuring that the formula ratio strictly matches the process requirements and eliminating the risk of emulsion stratification caused by inaccurate proportioning at the source.

Each stirring blade includes a blade base 810 and a blade body 820, with the blade body 820 connected to the second rotating rod via the blade base 810.

[0040] Both the servo motor and the solenoid valve are connected to the control mechanism, which in this embodiment is a microcontroller.

[0041] The first and second stirring mechanisms can simultaneously achieve high-shear emulsification and axial circulation, quickly breaking the interfacial tension between oil and water. The layered blade design of the storage tank 200 maintains emulsion homogeneity through upper and lower double-layer stirring, preventing solid particles from settling. The two mechanisms are independently controlled to adapt to the mixing needs at different stages—the former uses strong disturbance to form a stable emulsion, while the latter uses weak disturbance to maintain storage stability, jointly solving the pain point of traditional single-stirring mode being unable to balance initial mixing efficiency and long-term storage.
