Description

Technical Field

[0001] This utility model relates to the technical field of biofuel storage equipment, specifically to a bio-methyl ester insulated storage tank structure, which is particularly suitable for long-term insulated storage of bio-methyl ester. Background Technology

[0002] Biomethyl ester (the main component of biodiesel) is a renewable fuel produced from animal and vegetable oils through transesterification. It is environmentally friendly, biodegradable, and has excellent combustion performance. However, it has a high pour point (it typically solidifies below 0°C) and is prone to crystallization or increased viscosity at low temperatures, leading to transportation difficulties. Therefore, biomethyl ester must be stored at a suitable temperature (usually 15–25°C) to ensure its fluidity and stability.

[0003] Traditional bio-methyl ester storage tanks mostly use a single-layer steel structure, relying solely on the external insulation layer to maintain temperature. Their insulation performance is insufficient, and heat is easily lost through the tank body, leading to increased energy consumption. At the same time, their seismic performance is poor, and long-term use can easily cause weld cracks due to foundation settlement or vibration, leading to leakage risks. In addition, the sealing structure of existing storage tanks is easily affected by temperature changes, resulting in seal failure. Utility Model Content

[0004] This invention provides a structurally optimized bio-methyl ester insulated storage tank to solve the problems of poor insulation performance, insufficient shock resistance, and the sealing structure being easily affected by temperature in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a bio-methyl ester insulated storage tank structure, including a tank body, an insulation layer, and a support base. The tank body has a sealing cap at the top and a discharge port at the bottom. The tank body adopts a double-layer sleeve structure, consisting of an inner layer and an outer layer from the inside out, with a vacuum interlayer between the two layers. The insulation layer wraps around the outside of the tank body, and its outer surface is covered with an aluminum foil reflective film. The support base is located below the tank body and consists of a fixed plate and multiple adjustable legs. A damping rubber layer for shock absorption is provided between the fixed plate and the bottom of the tank body. The damping rubber layer contains a honeycomb-shaped metal skeleton. The multiple adjustable legs are arranged in a ring below the fixed plate. The sealing cap has a safety valve, and the outer side of the sealing cap is fixedly connected to the outer layer by multiple fastening bolts.

[0006] As a preferred technical solution of this utility model, the inner layer of the tank is made of stainless steel and the outer layer is made of carbon steel. The outer layer is provided with an upper baffle at the hollow interlayer and the upper baffle is welded and fixed to the inner layer.

[0007] As a preferred technical solution of this utility model, the upper baffle is provided with an inwardly recessed sealing groove in the middle, the sealing cover is provided with a corresponding protruding sealing block at the sealing groove, and a polytetrafluoroethylene sealing ring is provided inside the sealing groove.

[0008] As a preferred technical solution of this utility model, the vacuum interlayer is provided with support ribs arranged in a ring array. The cross-section of the support ribs is an I-shaped structure, and their inner side is welded and fixed to the inner layer, while their outer side is in elastic contact with the outer layer.

[0009] As a preferred technical solution of this utility model, the heat insulation layer is composed of alternating layers of nano-aerogel composite material and polyurethane foam layer, and the polyurethane foam layer has a distributed temperature sensor array embedded in it.

[0010] As a preferred embodiment of this invention, the outer surface of the aluminum foil reflective film is provided with an anti-corrosion coating.

[0011] As a preferred technical solution of this utility model, the fixing plate and damping rubber layer of the support base are an integral ring structure, and the discharge port is located in the middle of the support base. The outer side of the discharge port is wrapped with a heat insulation cover, wherein the discharge port and the inner layer are an integral structure, and the heat insulation cover and the outer layer are an integral structure.

[0012] As a preferred technical solution of this utility model, the adjustable support leg is composed of a fixed leg and a movable leg in the shape of angle iron. The movable leg and the fixed leg are fixed together by a double row of connecting components, and the fixed leg is provided with multiple strip holes that cooperate with bolts and nuts.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. The structure of this bio-methyl ester insulated storage tank, through the design of a double-layer tank body, vacuum jacket and composite insulation layer, can reduce heat loss by more than 40%;

[0015] 2. The structure of this bio-methyl ester insulated storage tank can effectively buffer vibration and prevent tank deformation through the damping rubber layer on the support base and the honeycomb metal skeleton. The installation height can also be adjusted through the adjustable support legs.

[0016] 3. The structure of this bio-methyl ester insulated storage tank uses distributed temperature sensors to provide real-time data feedback, facilitating precise temperature control. At the same time, the fixed sealing cover and the safety valve on the sealing cover can release internal pressure, thereby preventing changes in the sealing structure due to excessive internal pressure.
