Description

Technical Field

[0001] This utility model relates to the field of white oil production technology, specifically to a white oil filtration and storage system. Background Technology

[0002] Currently, most existing blending equipment for finished white oil production uses a single type of agitator, such as a common paddle agitator. This only generates a unidirectional flow of agitation, resulting in insufficient mixing of the white oil within the tank and the presence of dead zones. This is particularly problematic for high-viscosity white oils or blending processes with multiple added ingredients, making it difficult to achieve uniform mixing and affecting the quality stability of the white oil product. Most of the produced white oil is stored in tanks. Existing storage methods and structures are simple and lack sufficient leak protection. Leaks can severely pollute the storage area. Furthermore, the impact force of white oil entering an empty tank is significant. If it is poured into the tank during use, it will agitate the sediment at the bottom, requiring a long settling period before filling, thus impacting work efficiency. Utility Model Content

The raw material inlet is connected to the outlet of the turbine dynamic pipeline mixer through a bend. The two inlets of the turbine dynamic pipeline mixer are respectively connected to the white oil inlet pipe and the functional additive inlet pipe.

[0006] The other side of the mixing vessel is provided with a reflux liquid inlet, which is connected to a reflux pump located on the bottom side wall of the mixing vessel via a pipe. The inlet of the reflux pump is connected to the reflux outlet at the bottom of the mixing vessel via a white oil reflux pipe.

[0007] A mixing motor is provided at the top center of the mixing vessel. The output shaft of the mixing motor is connected to a stirring shaft that extends into the mixing vessel. The stirring shaft is equipped with a stirring paddle assembly for mixing the finished white oil.

[0008] The bottom side wall of the mixing vessel is also equipped with a pulse air pump. The outlet of the pulse air pump is connected to an air filling pipe that extends into the mixing vessel. A one-way valve is provided on the air filling pipe. An aeration disc is connected to the end of the air filling pipe.

[0010] The finished white oil outlet is connected to the inlet pipe of the storage tank.

[0011] The aeration disc is made of stainless steel and includes an outer annular tube, an inner annular tube, and a pair of horizontal tubes connecting the two. The top of one side of the outer annular tube is provided with an air inlet that connects to the end of the air filling tube. The surfaces of the outer and inner annular tubes are uniformly provided with multiple aeration holes with a diameter of 4-6 mm. The top of the mixing vessel is also provided with a pressure relief valve.

[0012] The reflux pump is installed on pump support A on the bottom side wall of the mixing vessel; the pulse air pump is installed on pump support B on the bottom side wall of the mixing vessel.

[0013] The bottom of the mixing vessel has a hemispherical structure.

[0014] The reflux outlet is located on one side of the finished white oil outlet at the bottom of the blending vessel.

[0015] The stirring paddle assembly consists of multiple sleeve sections fixed to the stirring shaft and four horizontal stirring rods evenly arranged on its side wall. The length of the horizontal stirring rods is one-third of the diameter of the mixing vessel.

[0016] The top of the leakage pool is equipped with a grid, and the storage tank is installed above the leakage pool via a support frame.

[0017] The bottom of the storage tank is a concave cone structure. The drain pipe is located in the middle of the cone structure, the dispersion plate is located directly above the drain pipe, and the transparent observation window is located at the bottom of the cone structure.

[0041] The bottom of the mixing vessel 21 has a hemispherical structure.

[0042] The reflux outlet is located on one side of the finished white oil outlet 40 at the bottom of the blending vessel 21.

[0045] The bottom of the storage tank 51 is a concave cone structure. The drain pipe is located in the middle of the cone structure, the dispersion plate 52 is located directly above the drain pipe, and the transparent observation window 55 is located at the bottom of the cone structure. The dispersion plate 52 is a cone structure and is coaxially arranged with the liquid inlet pipe through a connecting frame.

[0046] The upper part of the connecting frame is provided with a conical guide tube 58 with a top opening diameter larger than the bottom opening diameter.

[0047] Between the inner and outer tanks of the storage tank 51, there is a set of supporting stiffeners 57 arranged in a ring, and the supporting stiffeners 57 are provided with perforated holes.

[0048] Working principle: The white oil feed pipe and the functional additive feed pipe respectively deliver the refined white oil raw material and the functional additive to the two inlets of the turbine dynamic pipeline mixer. After initial mixing, they flow through the raw material feed interface at the top of the blending vessel into the blending vessel body. Then, the refined white oil raw material and the functional additive are stirred and mixed by multiple sets of horizontal stirring rods of the stirring paddle assembly, combined with the aeration and dispersion of the pulse air pump and the bottom reflux of the return pump, so as to achieve uniform mixing of the refined white oil raw material and the functional additive.

[0049] The leakage pool 50 and the storage tank 51 installed in the leakage pool 50 are provided. The top of the storage tank 51 is provided with an inlet pipe and the bottom of the inlet pipe is provided with a dispersion plate 52. The storage tank 51 near the bottom is provided with a drain pipe and the bottom of the storage tank 51 is provided with a sewage pipe. The storage tank 51 has a double-layer hollow structure and the bottom of the outer layer of the tank is provided with a transparent observation window 55.

[0050] The leakage pool 50 is located below the storage tank 51. In case of leakage, the white oil will flow into the leakage pool 50 for collection, preventing environmental pollution. When the white oil is injected into the storage tank 51, the dispersion plate 52 disperses the white oil in all directions, reducing the impact on the bottom of the storage tank 51. The storage tank 51 has a double-layer hollow structure, which can provide insulation and further improve the safety performance of the storage tank 51 to prevent leakage.

[0051] Furthermore, a grid 56 is provided on the top of the leakage pool 50, and the storage tank 51 is installed above the leakage pool 50 via a support frame.

[0052] The top of the leakage pool 50 is parallel to the ground. The grid mesh 56 facilitates workers to walk on it. The top of the leakage pool 50 is equipped with a grid frame. The grid mesh 56 is assembled from multiple pieces. Each grid mesh 56 is movably installed in the corresponding grid frame space and can be disassembled and installed individually, making it convenient for workers to enter the leakage pool 50. The support frame extends into the bottom of the leakage pool 50.

[0053] Preferably, the bottom of the storage tank 51 is a concave cone structure, the drain pipe is located in the middle of the cone structure, the dispersion plate 52 is located directly above the drain pipe, and the transparent observation window 55 is located at the bottom of the cone structure.

[0054] The conical structure keeps the white oil deposits centered at the bottom center. The drain pipe is located above the conical structure, so only the white oil located above the conical structure can be drained during discharge. After discharge, the deposits can be cleaned up through the sewage pipe.

[0055] If a leak occurs inside the inner tank of storage tank 51, the contents will flow into the hollow structure. The transparent observation window 55 allows for a direct view of whether there is a leak in the inner tank.

[0056] Preferably, the dispersion plate 52 has a conical structure, and the dispersion plate 52 is coaxially arranged with the liquid inlet pipe through a connecting frame.

[0057] After the white oil falls onto the dispersing plate 52, it can be smoothly and evenly dispersed in all directions. In this case, the height of the dispersing plate 52 is controlled so that the dispersed white oil can flow down from the side walls of the storage tank 51, avoiding direct scouring to the bottom of the storage tank 51.

[0058] Furthermore, the upper part of the connecting frame is provided with a conical guide tube 58 with a top opening diameter larger than the bottom opening diameter, and the liquid inlet pipe is provided with a conical guide tube mounting protrusion. The conical guide tube 58 is movably installed in the liquid inlet pipe. The diameter of the dispersion plate 52 is larger than the bottom opening diameter of the conical guide tube 58 and smaller than the top opening diameter of the conical guide tube 58.

[0059] The conical guide tube 58 is used to concentrate the injected white oil into the center and onto the dispersing plate 52, and then disperse it evenly in all directions through the dispersing plate 52. The conical guide tube 58 is provided with a rim that matches the mounting protrusion of the conical guide tube. By placing the rim on the mounting protrusion of the conical guide tube and lifting it upwards, the conical guide tube 58 and the dispersing plate 52 can be quickly removed from the liquid inlet pipe.

[0060] Furthermore, a set of supporting stiffeners 57 are arranged in a ring between the inner and outer tanks of the storage tank 51, and the supporting stiffeners 57 are provided with perforated holes.

[0061] The supporting stiffener 57 strengthens the side wall of the storage tank 51. At the same time, there is a gap between the lowest end of the supporting stiffener 57 and the sewage pipe to keep the conical bottom of the storage tank 51 connected. If there is a leak in the inner wall of the storage tank 51, the observation window 55 can quickly detect it.

[0062] The above-described embodiments are only intended to illustrate the technical solution and features of this utility model, and are intended to enable those skilled in the art to implement them. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model are within the scope of protection of this utility model.
