Description

Fuel tank capable of preventing liquid from shaking

Technical Field

The utility model relates to a fuel accumulator technical field, concretely relates to prevent that liquid rocks fuel tank.

Background

At this stage, liquid fuel is widely used in various fields with large energy consumption as an energy source which is easy to store, transport and control, and is one of the most widely used energy sources. The liquid fuel has about 30% lighter heat than the solid fuel with the same amount of heat energy, occupies about 50% less space, and has higher convenience compared with the storage convenience of the solid fuel and the gas fuel. The content of waste in the liquid fuel is small, the heat effect generated by combustion is high, and the combustion flame similar to that of gas fuel can be obtained.

Compared with solid fuel and gas fuel, the storage space condition required by the liquid fuel is not strict, and the requirements of the liquid fuel on the fuel tank only need to meet the basic functional requirements of the fuel tank, such as corrosion resistance, high strength and the like. In terms of safety factor, liquid fuels are more stable than gaseous fuels, so the storage space requirements are not as high as those for gaseous fuels.

Liquid fuels have the characteristic of being prone to sloshing, a common phenomenon of fluid movement, which typically occurs in tanks that are partially unfilled with liquid. If the liquid fuel in the fuel tank does not fill the entire fuel tank, the liquid may follow the sloshing of the fuel tank and swing in the remaining space. Excessive sloshing can cause bubbles to appear on the surface of part of the liquid fuel, so that the purity of the fuel and the efficiency of subsequent reaction are affected.

The degree of liquid sloshing is also proportional to the volume of the liquid, with the greater the volume of the liquid, the greater the degree of sloshing. The existing technical scheme is that a plurality of fixed plates or movable plates with different structures are arranged inside the fuel tank so as to reduce the shaking degree of liquid. However, this solution divides the fuel tank into several parts, and separates the fuel in each part, so that when the fuel tank shakes, the fuel will only shake in each part, compressing the space where the fuel can shake, thereby achieving the purpose of reducing the shaking degree of the liquid. However, the fuel in each part still shakes along with the fuel tank, and the fuel cannot play a role in preventing shaking to the maximum extent, and the anti-shaking effect is not ideal.

In addition, the non-removable structure of the conventional fuel tank makes the cleaning and routine maintenance of the fuel tank difficult.

The specific implementation mode is as follows:

in order to enhance the understanding of the present invention, the following detailed description will be made in conjunction with the embodiments and the accompanying drawings. The utility model discloses the accessible is implemented as follows:

referring to fig. 1-3, a liquid sloshing prevention fuel tank includes a fuel tank body 1, a floating plate 2, a floating plate support 3, and a support rail 4; the fuel tank 1 is for storing liquid fuel. The floating plate 2 is arranged inside the fuel tank body 1, the floating plate 2 isolates the liquid fuel from the gas, the edge of the floating plate 2 is in clearance fit with the barrel wall of the fuel tank body 1 to isolate a gas-liquid space, and a certain slight clearance is reserved between the floating plate 2 and the barrel wall around the fuel tank body 1 and is used for mutually ventilating the upper space and the lower space, balancing the air pressure difference of the inner space of the fuel tank body 1 and enabling the fuel to flow into the liquid space. The design can avoid the problem that the fuel cannot be output to the reaction device from the output port at the lower part of the fuel tank body 1 due to the gas pressure difference inside and outside the space; it can also be used as a gas-liquid conversion path between gas and liquid space when the fuel tank 1 is filled with liquid. The bracket guide rail 4 is arranged on the barrel wall of the fuel tank body 1, and the floating plate 2 moves up and down along the bracket guide rail 4 through the floating plate bracket 3 to form a stable sliding block system. The floating plate bracket 3 is used for fixing the floating plate 2 and the bracket guide rail 4 mutually. The floating plate 2 needs to be fixed by using the floating plate support 3, otherwise, the floating plate 2 will impact the fuel tank along with the shaking of the fuel because of the gap between the floating plate and the peripheral barrel wall of the fuel tank 1, which is not beneficial to the long-term use of the fuel tank.

The utility model discloses a space between fuel and the contactable gas plays the function that prevents fuel and rock in the application compression fuel tank. The degree of sloshing of the fuel is proportional to the degree of sloshing during transportation of the fuel and inversely proportional to the degree of loading of the fuel tank. For example, the greater the degree of sloshing during fuel transportation, the greater the fluidity of the fuel; the smaller the degree of loading of the fuel tank, the larger the gas space, and the larger the sloshable space of the liquid fuel. After the gas space is compressed, the contact area of gas and liquid is reduced, the gas-liquid space can be effectively isolated, the aim of reducing the shaking degree of liquid fuel is achieved, the quality of the fuel in the fuel tank is ensured, and pure fuel is provided for the reaction of the reactor.

The top of the floating plate 2 and the edge of the floating plate 2 form an inclined angle, so that the input fuel can be prevented from being accumulated on the top of the floating plate 2.

The floating plate 2 is made of PMI foam board with high strength, so that the floating plate 2 can float on liquid, and the space between gas and liquid can be effectively isolated.

The support guide rail 4, the floating plate 2 and the floating plate support 3 are combined with each other to form a movable and fixed device, certain friction exists between the support guide rail 4 and the floating plate 2 and between the support guide rail 4 and the floating plate support, the problem of friction between the floating plate 2 and the support guide rail 4 needs to be determined based on gravity borne by the floating plate 2 and buoyancy thereof, the support guide rail 4 with a large friction coefficient is selected as far as possible under the condition that the friction is smaller than the gravity borne by the floating plate and the buoyancy thereof, and the larger friction between the floating plate 2 module and the support guide rail 4 can reduce the influence of the floating plate 2 module on shaking of the fuel tank, so that the function effect of preventing liquid from shaking is more obvious. The friction coefficient between the bracket guide rail 4 and the floating plate 2 and between the bracket guide rail and the floating plate bracket 3 is between 0.1 and 0.2. Its purpose can increase the sliding resistance of kickboard support 3 in support guide rail 4, avoids the fuel tank at the in-process that rocks, because of the coefficient of friction between kickboard support 3 and support guide rail 4 is less, leads to kickboard support 3 to be too big on support guide rail 4 gliding frequency from top to bottom, and the material exchange in gas space and the liquid space is too frequent, makes the effect of preventing rocking reduce. But the gravity and buoyancy of the floating plate 2 cannot be lower than the friction force, otherwise the floating plate 2 cannot be stabilized at the liquid level.

The top of the fuel tank body 1 is provided with a detachable sealing top cover 5. The sealing top cover 5 is matched with the edge of the fuel tank body 1 through a buckling structure 6. And a sealing rubber gasket is arranged at the connecting position of the sealing top cover 5 and the fuel tank body 1. The design can effectively play a role of sealing when the sealing top cover 5 of the fuel tank is closed, and prevent liquid from overflowing when the fuel tank is filled. The openable cover is also beneficial to daily cleaning and maintenance of the interior of the fuel tank.

The sealing top cover 5 is provided with a fuel inlet 7 and a vent valve 8. The fuel inlet 7 is an inlet through which external fuel enters the fuel tank 1, and the vent valve 8 is a device for maintaining the balance between the internal pressure and the external pressure of the fuel tank 1.

The bottom of the fuel tank body 1 is provided with a fuel outlet 9, and the fuel outlet 9 is positioned at the bottom of the fuel tank body 1 and is used for outputting fuel from the inside of the fuel tank body 1 to the outside space.

The using method comprises the following steps: the fuel is input into the fuel tank body 1 through the fuel input port 7 of the sealing top cover 5 of the fuel tank body 1, the fuel reaches the top of the floating plate 2 after flowing in, the liquid at the top can be effectively guided to two sides of the floating plate 2 by the inclination angle of the top of the floating plate 2, and the fuel flows into the liquid space of the fuel tank body 1 through the gap between the floating plate 2 and the barrel wall of the fuel tank body 1. As the liquid surface rises, the floating plate 2 rises due to its own buoyancy. When fuel begins to export consumption, the liquid level position can descend, and gas can flow to the liquid space, and the floating plate 2 can slowly descend to the liquid level position because of the gravity that self received this moment, will flow to the gaseous extrusion return gas space in liquid space, plays the effect that reduces the area of contact of gas and liquid once more.

Finally, it should be noted that: the above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
