DETAILED DESCRIPTION

[0019] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] As shown in the figure:

[0021] An alcohol-based fuel intelligent explosion-proof and filling-proof tank comprises a tank body 1, wherein the tank body 1 is separated into a confluence chamber (for smooth liquid discharge) by a porous partition 15 near the bottom, and the upper space of the porous partition 15 is filled with a fire-retardant filler 17; an air pipe 2, a filling pipe 4 and a liquid outlet pipe 3 are installed on the top of the tank body 1, wherein the liquid outlet pipe 3 extends downward into the confluence chamber; a safety valve 21 is connected to the side wall of the air pipe 2, and a soft valve 22 and a breathing valve 23 are installed in sequence at the top; the filling pipe 4 is installed with Angle valve 6 and intelligent anti-filling valve body 5, the outer wall of the angle valve 6 is pasted with a QR code; a nut sleeve 31 is installed at the top of the liquid outlet pipe 3, and a reverse thread connector 32 is welded on the inlet side of the liquid outlet control valve 33. The nut sleeve 31 is screwed into the reverse thread connector 32 to complete the connection between the liquid outlet pipe 3 and the liquid outlet control valve 33. A glass bead 321 is placed in the reverse thread connector 32. The diameter of the glass bead 321 is smaller than the inner diameter of the reverse thread connector 32, and larger than the inlet inner diameter of the liquid outlet control valve 33 and the outlet inner diameter of the nut sleeve 31.

[0022] The utility model adopts a fireproof and flame retardant filler 17 to fill the tank body 1, which can be a strip of continuous aluminum-magnesium alloy foil, etc. The meshes in the explosion-suppressing material stack formed by the fireproof and flame retardant filler 17 form a honeycomb structure, and the honeycomb structure can curb the spread of flames; at the same time, this honeycomb structure has a high surface efficiency per unit volume, and can quickly absorb most of the heat released by combustion, so that the temperature after the combustion reaction is greatly reduced, the expansion degree of the reaction gas is greatly reduced, and the pressure value of the container is not increased much; essentially, the potential safety hazards in the process of terminal use of alcohol-based fuels are solved.

[0023] Since alcohol-based fuel is a flammable and dangerous substance, in order to avoid illegal private filling, the utility model installs an intelligent anti-filling valve body 5 between the angle valve 6 and the filling pipe 4. In order to facilitate installation, the inventor processes the intelligent anti-filling valve body 5 and the angle valve 6 into one piece. The intelligent anti-filling valve body 5 has an anti-filling valve core 7, which includes an upper valve core 71 and a lower valve core 73. The upper valve core 71 is provided with a liquid inlet flow channel 711, and the lower valve core 73 is provided with a liquid inlet flow channel 712. A drainage channel 731 is provided, and a flap chamber 72 is provided between the upper valve core 71 and the lower valve core 73. An oblique sealing surface 723 is provided at the bottom of the flap chamber 72. The drainage channel 731 is connected to the oblique sealing surface 723. A ferromagnetic flap 721 that can be freely flipped inside is provided in the flap chamber 72, and a permanent magnet 722 is fixed on the upper side of the oblique sealing surface 723. Under normal circumstances, under the action of the permanent magnet 722 and its own weight, the ferromagnetic flap 721 will fit the oblique sealing surface 723. One side, thereby blocking the discharge flow channel 731, to avoid private filling, even if the tank body 1 is inverted, due to the effect of the permanent magnet 722, the ferromagnetic flap 721 will not open under gravity, the reliability is higher, when it is necessary to return to the manufacturer for filling, the angle valve 6 carries the QR code of the company's copper bottle filling, and the QR code reader at the end of the filling gun recognizes the company's QR code. If the verification is correct, the QR code reader sends a signal to the filling system, and the system generates a strong magnet for the electromagnet module power supply. The electromagnet module approaches the outer wall of the intelligent anti-filling valve body 5, retracts the ferromagnetic flap 721, opens the discharge flow channel 731, and quantitatively fills the tank body 1 with alcohol-based fuel (the prior art is the physical combination of the scanning gun and the electromagnet module. After the scanning gun recognizes the correct information, it starts the power supply of the electromagnet module). Of course, this case is just an improved case by the inventor, which can avoid circumventing the anti-filling mechanism by inverting, and other intelligent anti-filling valve bodies 5 can also be used instead.

[0024] Similarly, in order to avoid filling from the liquid outlet pipe 3, a glass bead 321 is placed in the reverse thread connector 32 of the utility model. The diameter of the glass bead 321 is smaller than the inner diameter of the reverse thread connector 32, but larger than the inlet inner diameter of the liquid outlet control valve 33 and the outlet inner diameter of the nut sleeve 31. In this way, when supplying liquid, the glass bead 321 will be pushed up. Since normal pressure liquid supply is adopted, the pressure is relatively low. The installation of a check valve is not applicable because it has a large opening pressure. The glass bead 321 will be pushed up under the action of a very small liquid flow and will not affect the liquid supply. However, if filling is to be carried out, the glass bead 321 will block the liquid outlet pipe 3 under its own weight, so it is impossible to add from the outside. Even if the tank body 1 is tilted, the glass bead 321 will still block the liquid outlet pipe 3, thereby preventing the alcohol-based liquid fuel from being filled from the liquid outlet pipe 3 (only liquid can be discharged but not filled).

[0025] In order to facilitate transportation and installation, a handle 13 is provided on the top of the tank body 1, and a base 14 is provided on the bottom of the tank body 1. At the same time, the upper and lower sides of the peripheral wall of the tank body 1 have concave annular grooves 11, and rubber rings 12 are embedded in the annular grooves 11 to play a buffering role and facilitate transportation.

[0026] In order to facilitate the later cleaning, a blocked sewage pipe 16 is also provided at the bottom of the tank body 1. This structure is designed for fuel manufacturers to prevent users from opening it easily, but the manufacturer can still clean it later.

[0027] In order to facilitate management and user use, a traceability QR code is also affixed to the wall of the tank body 1 to record information such as the factory, use, number of fillings and time of the alcohol-based fuel intelligent explosion-proof and refillable tank, complete traceability, and thus achieve closed-loop management.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
