Abstract
Description
Technical Field
[0001] This utility model relates to the field of white oil processing technology, specifically to a storage tank for finished white oil products. Background Technology
[0002] Current white oil storage tanks often fail to consider the issue of water contamination during construction. Because white oil inevitably comes into partial contact with the external environment during transportation or storage, it inevitably absorbs a small amount of water, generally below 0.5%. This can lead to a small amount of sediment settling at the bottom of the storage tank during discharge, thus affecting the quality of some finished white oil products. Existing white oil storage tanks are often tall, vertical tanks, which increases the difficulty of maintenance and cleaning, consuming significant manpower and resources. Utility Model Content
[0003] The purpose of this invention is to provide a storage tank for finished white oil products to address the aforementioned deficiencies.
[0004] A storage tank for finished white oil includes a tank body, which is a horizontal tank body. The top of the tank body is provided with a white oil inlet and a manhole. The tank body includes an integrally formed upper cylindrical part, a lower conical bucket-shaped part, and a bottom hollow semi-ellipsoidal part. The volume of the bottom hollow semi-ellipsoidal part is 0.5% of the volume of the tank body.
[0005] The storage tank body is provided with a storage tank support frame below the tank body. The storage tank support frame includes a top rectangular frame fixed to the upper cylindrical part and a set of support legs symmetrically arranged on both sides thereon.
[0006] The lowest point of the hollow semi-ellipsoidal section at the bottom is equipped with a white oil discharge pipe. From top to bottom, the white oil discharge pipe is fitted with a butterfly valve and an electric regulating valve (the butterfly valve is suitable for large-diameter white oil unloading pipelines, such as the connection between storage tanks and large oil pipelines. When unloading white oil, the pipeline diameter is large, and using a butterfly valve can meet flow requirements while reducing valve cost and installation difficulty. The electric regulating valve precisely controls the valve opening through an electric actuator, thereby achieving precise regulation of the white oil unloading flow rate). Between the butterfly valve and the electric regulating valve, the white oil discharge pipe is equipped with a downward-sloping drain pipe. From top to bottom, the drain pipe is fitted with a ball valve and a needle valve (the ball valve is installed on the drain pipe near the storage tank; under normal circumstances, the ball valve is closed to prevent white oil leakage; it is opened when drainage is needed. The needle valve is installed after the ball valve to more accurately control the drainage speed and flow rate, preventing excessively rapid drainage from causing white oil entrainment, resulting in waste and pollution).
[0007] Preferably, a set of support legs includes four support columns and a rectangular connecting frame disposed in the middle, with the tops of the four support columns fixedly connected to the upper cylindrical part.
[0008] Preferably, the width of the top rectangular frame is smaller than the diameter of the upper cylindrical portion.
[0009] Preferably, the total height of the storage tank body and the storage tank support frame is no more than 5m.
[0010] Preferably, one or more grounding wires with good conductivity are also provided between the tank body and the ground.
[0011] Preferably, the tank body is made of 316L stainless steel. A radar level gauge is installed inside the tank to avoid direct contact with the white oil, reducing the risk of corrosion and clogging. A magnetic level gauge is also provided as a backup to improve the reliability of the measurement.
[0012] The advantages of this invention are: it facilitates the settling and discharge of water, avoiding any impact on the quality of the white oil product; and it greatly reduces the difficulty of subsequent maintenance and cleaning of the white oil storage tank. Attached Figure Description

[0020] As shown in the attached figure, a storage tank for finished white oil includes a tank body 100, which is a horizontal tank. The top of the tank body 100 is provided with a white oil inlet 101 and a manhole 102. The tank body 100 includes an integrally formed upper cylindrical part 103, a lower conical funnel-shaped part 104, and a bottom hollow semi-ellipsoidal part 105. The volume of the bottom hollow semi-ellipsoidal part 105 is 0.5% of the volume of the tank body 100. During the storage process, the white oil will come into contact with the external environment to a certain extent and will inevitably absorb a small amount of water, generally less than 0.5%. The bottom hollow semi-ellipsoidal part 105 is used to collect the sediment water.
[0021] The storage tank body 100 is provided with a storage tank support frame below it. The storage tank support frame includes a top rectangular frame 111 fixedly connected to the upper cylindrical part 103 and a set of support legs 112 symmetrically arranged on both sides thereon.
[0022] The lowest point of the hollow semi-ellipsoidal section 105 is provided with a white oil discharge pipe 113. From top to bottom, the white oil discharge pipe 113 is equipped with a butterfly valve 114 and an electric regulating valve 116. The butterfly valve is suitable for large-diameter white oil unloading pipelines, such as the connection between storage tanks and large oil pipelines. When unloading white oil, the pipeline diameter is large; using a butterfly valve can meet flow requirements while reducing valve cost and installation difficulty. The electric regulating valve precisely controls the valve opening through an electric actuator, thereby achieving precise regulation of the white oil unloading flow rate. Between the butterfly valve 114 and the electric regulating valve 116, the white oil discharge pipe 113 is equipped with a downward-sloping drain pipe 117. From top to bottom, the drain pipe 117 is equipped with a ball valve 118 and a needle valve 119. The ball valve is installed on the drain pipe near the storage tank. Under normal circumstances, the ball valve is closed to prevent white oil leakage; it is opened when drainage is needed. Install a needle valve after the ball valve to more accurately control the drainage speed and flow rate, preventing excessively fast drainage from causing white oil to be carried out, resulting in waste and pollution.
[0023] In another technical solution, a set of support legs 112 includes four support columns 106 and a rectangular connecting frame 107 disposed in the middle. The tops of the four support columns 106 are fixedly connected to the upper cylindrical part 103, making it more stable and reliable.
[0024] In another technical solution, the width of the top rectangular frame 111 is smaller than the diameter of the upper cylindrical portion 103.
[0025] In another technical solution, the total height of the storage tank body 100 and the storage tank support frame is no more than 5m, which facilitates subsequent maintenance and cleaning.
[0026] In another technical solution, one or more grounding wires with good conductivity are also provided between the storage tank body 100 and the ground. This conducts static electricity to the ground, preventing static electricity buildup from causing fires or explosions.
[0027] In another technical solution, the storage tank body 100 is made of 316L stainless steel. A radar level gauge is installed inside the storage tank body 100 to avoid direct contact with white oil, reducing the risk of corrosion and blockage. A magnetic level gauge is also provided as a backup to improve the reliability of the measurement.
[0028] Working principle: The finished white oil enters the storage tank through the white oil inlet at the top of the tank. When needed, the oil density is generally less than 880 kg / m³. 3 The density of water is 1000 kg / m³. 3Utilizing density differences, water and oil separate very thoroughly under static conditions (generally after 8 hours). Before each oil discharge, the sediment must be drained first. First, open the butterfly valve, then the ball valve and needle valve in sequence to drain the sediment. Observe that oil is coming out, then close the ball valve and needle valve to improve product quality. Finally, open the electric regulating valve to control the discharge speed of the white oil by adjusting its flow rate.
[0029] 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. Anything not described in detail is prior art.
