Description

Technical Field

[0001] This utility model relates to the field of liquid fuel equipment technology, specifically to an alcohol-based fuel supply system. Background Technology

[0002] In the mountainous regions of southwestern my country, such as Yunnan and Guizhou, the unique geological conditions present significant challenges to natural gas pipeline construction, including difficult rock excavation, long construction periods, and high costs. This has resulted in many residential areas and privately-owned restaurants being unable to connect to piped gas and instead relying on gas cylinders for energy. However, gas cylinders have revealed significant safety hazards over long-term use. Their high-pressure storage characteristics easily lead to risks such as corrosion, leakage, and explosions. Furthermore, due to the unregulated storage environment at the user end, the accident rate is far higher than that of piped gas systems, making it a critical issue for regional public safety management.

[0003] Alcohol-based fuels can replace wood, charcoal, biomass pellets, coal, diesel, and liquefied petroleum gas. Their combustion produces carbon dioxide and water, helping to reduce environmental pollution, carbon monoxide poisoning, and sulfide emissions, thus minimizing harm to human health and aligning with the development principles of carbon emission reduction and carbon neutrality. Furthermore, alcohol-based liquid fuels offer advantages such as atmospheric pressure storage and high calorific value, gradually becoming an ideal energy source to replace gas cylinders. However, current alcohol-based fuel systems often employ a direct connection between the storage tank and the combustion end. While this reduces initial installation costs, it presents the following technical challenges in actual operation:

[0004] 1. Alcohol-based fuel storage tanks are usually large in capacity. In the mode of direct connection with the combustion end, the fuel consumption rate of the combustion end is not constant. When multiple combustion devices are running at the same time or when there is a peak in gas consumption, the fuel consumption increases sharply. The storage tank is difficult to respond quickly and supply fuel stably, which leads to unstable flame or even flameout at the combustion end.

[0005] 2. When the fuel level in the storage tank drops, the fuel delivery pressure becomes insufficient due to the reduced level difference, which also affects the stability of the fuel supply, interferes with the normal operation of the equipment, and reduces work efficiency. Utility Model Content

[0006] This invention provides an alcohol-based fuel supply system that can solve the technical problem of unstable fuel supply caused by direct connection between existing alcohol-based fuel storage tanks and combustion end.

[0007] This application provides the following technical solution:

[0008] An alcohol-based fuel supply system includes a storage tank and a control box. The control box contains a transfer box, a delivery pump, and a controller. The storage tank is connected to the inlet of the transfer box via a feed pipe, and the outlet of the transfer box is connected to the combustion end via a discharge pipe. The delivery pump is installed on the feed pipe and is electrically connected to the controller.

[0009] Beneficial effects:

[0010] 1. In the original direct connection mode between the storage tank and the combustion end, the fluctuation of the combustion end's fuel demand directly affects the output of the storage tank. However, the transfer box in this system can serve as a buffer zone. When the combustion end's fuel demand suddenly increases, the transfer box can quickly provide fuel to the combustion end, avoiding flame instability or flameout caused by the storage tank's untimely response, thus effectively ensuring a stable fuel supply.

[0011] 2. The transfer box acts as an isolation between the storage tank and the combustion end. If backfire occurs at the combustion end, the transfer box can prevent the flame from spreading to the storage tank, reducing the probability of serious safety accidents such as explosions and improving the safety of the entire system.

[0012] Furthermore, the transfer box is also equipped with a low-level gauge and a high-level gauge that are electrically connected to the controller.

[0013] Beneficial effects:

[0014] 1. When the fuel level drops to the set low level threshold, the low level gauge will transmit a signal to the controller. After receiving the signal, the controller will immediately start the transfer pump to replenish fuel from the storage tank to the transfer tank. This mechanism ensures that there is always enough fuel in the transfer tank to supply the combustion end, avoiding unstable combustion or even flameout due to insufficient fuel, thus ensuring the stable operation of the entire alcohol-based fuel supply system.

[0015] 2. The high-level gauge functions when the fuel level in the transfer tank reaches the set high-level threshold. It sends a signal to the controller, which then stops the transfer pump to prevent overfilling of the transfer tank. This not only avoids waste and safety hazards caused by fuel overflow, but also ensures that the transfer pump will not be damaged by prolonged idling, extending the service life of the equipment and maintaining the stability of the system operation.

[0016] Furthermore, a one-way ventilation valve is also installed on the top of the transfer box.

[0017] Beneficial effects: When fuel is used at the combustion end, the liquid level in the transfer box drops, the gas space inside the box increases, the gas pressure decreases, and the one-way ventilation valve allows air to enter in time, avoiding the formation of negative pressure inside the box, ensuring that fuel can flow smoothly from the discharge pipe to the combustion end, and preventing fuel supply disruptions due to negative pressure.

[0018] Furthermore, the control box includes a box body and a box door. The transfer box, controller, and delivery pump are housed inside the box body, and the box door is detachably connected to the box body.

[0019] Beneficial effects: During normal use, the enclosure door can enclose the transfer box, controller, and transfer pump, preventing accidental contact with these devices, especially the energized controller and high-speed transfer pump, thus reducing the risk of electric shock and mechanical injury. Furthermore, the detachable door structure facilitates maintenance and replacement.

[0020] Furthermore, the cabinet door is equipped with control buttons and indicator lights that are electrically connected to the controller; the cabinet body is also equipped with an alarm that is electrically connected to the controller.

[0021] Beneficial effects: Positioning the control buttons on the control box door allows operators to directly control the system without opening the control box, such as starting, stopping, or resetting, improving ease and timeliness of operation. Indicator lights provide a clear view of the system's operating status, such as whether the transfer pump is working, whether the fuel supply is normal, and whether the liquid level is within the normal range. When an abnormality occurs, such as a low liquid level, the controller will trigger an alarm with sound or light, promptly alerting the operator and enabling immediate action to prevent accidents or escalation.

[0022] Furthermore, the controller is wirelessly connected to the user terminal.

[0023] Beneficial effects: Operators can remotely operate the controller on the user terminal and flexibly adjust the system's operation according to actual needs. For example, in case of an emergency, operators do not need to go to the site to remotely control the start and stop of the delivery pump, close relevant valves, etc. through the user terminal, so as to avoid the occurrence or escalation of safety accidents and ensure the safety of the system and personnel.

[0024] Furthermore, the storage tank includes a base, a tank body, and a guardrail plate installed on the top of the tank body. The tank body is also provided with multiple outwardly protruding annular anti-collision strips.

[0025] Beneficial effects:

[0026] 1. By installing a base at the bottom of the storage tank, the stability of the tank can be improved, preventing it from tipping over. On the other hand, the base can also reduce the impact between the bottom of the tank and the ground or other objects, thus extending the service life of the tank.

[0027] 2. By installing outward-protruding ring-shaped anti-collision strips on the outside of the tank, the problem of direct collisions between storage tanks and between storage tanks and other equipment during transportation can be reduced. In addition, when the storage tank falls over, the protruding ring-shaped anti-collision strips can also play a certain role in protecting the tank body and prevent the tank body from directly hitting the ground.

[0028] Furthermore, the fence panel has an arc-shaped structure, and a handrail opening is provided on the fence panel, with a widened part for the handle opening.

[0029] Beneficial effects: The handrail opening makes it easier to move the tank, and the widened part can reduce the squeezing effect of the handrail opening on the palm, avoiding the injury to the hand during handling.

[0030] Furthermore, the widened section is an integral structure with the fence panel, and the widened section is bent inward into an arc shape; or the widened section is welded to the handle part of the handrail.

[0031] Beneficial effects: The integrated structure of the widened section and the fence panel facilitates processing and molding, reduces manufacturing costs, and allows the widened section to be set into different shapes and then connected to the handrail opening.

[0032] Furthermore, the top of the tank is equipped with an inlet / outlet and an air vent, with an air inlet check valve installed in the air vent; a pressure relief valve is also installed on the tank.

[0033] Beneficial effects:

[0034] 1. During transportation, the liquid inside the tank may shake, leading to increased pressure. By installing a pressure relief valve, the pressure can be automatically released when the pressure is too high, thus improving the safety of use.

[0035] 2. As fuel is output, the space inside the tank gradually increases, creating a certain degree of vacuum, which makes it difficult for fuel to flow out smoothly. Setting up an air exchange port allows air to enter the tank in time, breaking the vacuum, preventing air blockage, and ensuring that fuel can flow out smoothly from the inlet and outlet for normal use.

[0036] 3. After filling, inert gas can be injected into the tank through the vent to form a gas film, which provides some protection for the alcohol-based fuel. Attached Figure Description

[0041] The following detailed description illustrates the specific implementation method:

[0042] The markings in the accompanying drawings include: storage tank 1, tank body 10, annular anti-collision strip 101, inlet / outlet 102, ventilation port 103, base 11, fence plate 12, handrail opening 121, widened section 122, control box 2, box body 21, inner cavity 210, alarm 211, box door 22, control button 221, indicator light 222, connecting seat 23, mounting lug 24, pin 25, transfer box 3, low level gauge 31, high level gauge 32, ventilation pipe 33, transfer pump 4, controller 5, feed pipe 100, and discharge pipe 200.

[0043] Example 1

[0044] like Figure 1-2 As shown, the alcohol-based fuel supply system includes a storage tank 1 and a control box 2. The control box 2 is equipped with a transfer box 3, a transfer pump 4, and a controller 5. The storage tank 1 is connected to the inlet of the transfer box 3 through a feed pipe 100, and the outlet of the transfer box 3 is connected to the combustion end through a discharge pipe 200. The transfer pump 4 is installed on the feed pipe 100 and is electrically connected to the controller 5. In this embodiment, the transfer box 3 is also equipped with a low level gauge 31 and a high level gauge 32, which are electrically connected to the controller 5. When the controller 5 receives a signal from the low level gauge 31, it controls the transfer pump 4 to run and transport the fuel in the storage tank 1 to the transfer box 3. When the controller 5 receives a signal from the high level gauge 32, it controls the transfer pump 4 to stop transporting fuel.

[0045] like Figure 2 As shown, the control box 2 includes a box body 21 and a door 22. The door 22 is detachably connected to the box body 21. An inner cavity 210 is provided inside the box body 21. The bottom of the transfer box 3 is fixed to the bottom of the inner cavity 210 of the box body 21. The delivery pump 4 is located on one side of the inner cavity 210, and the controller 5 is located on the top wall of the inner cavity 210. Specifically, as shown... Figure 3 As shown, in this embodiment, at least two mounting lugs 24 are provided on one side of the housing 21, and a connecting seat 23 for fitting over the mounting lugs 24 is provided on one side of the door 22. Both the connecting seat 23 and the mounting lugs 24 are provided with pin holes. During installation, an L-shaped pin 25 is inserted into the pin hole to fix the door 22 to one side of the housing 21.

[0046] In this embodiment, a one-way ventilation valve is also provided on the top of the transfer box 3. Specifically, a ventilation pipe 33 extending to the outer side of the top of the box body 21 is provided on the top of the transfer box 3, and the one-way ventilation valve is located inside the ventilation pipe 33. When fuel is used at the combustion end, causing the liquid level in the transfer box 3 to drop, the gas space inside the box increases and the gas pressure decreases. The one-way ventilation valve allows air to enter in time, preventing the formation of negative pressure inside the box and ensuring that fuel can flow smoothly from the discharge pipe 200 to the combustion end, preventing fuel supply obstruction due to negative pressure. A connecting pipe is provided at the outlet of the transfer box 3, extending from the bottom of the box body 21 for easy connection to the discharge pipe 200. The inlet of the transfer box 3 is located at the top and is connected to one end of the conveying pump 4 through a pipe. The other end of the conveying pump 4 is connected to the feed pipe 100 through a pipe.

[0047] The door 22 is equipped with control buttons 221 and indicator lights 222 that are electrically connected to the controller 5. Specifically, in this embodiment, the control buttons 221 include a power button, an emergency stop button, and a reset button, allowing operators to directly operate the system without opening the door 22, such as starting, stopping, or resetting, thus improving the convenience and timeliness of operation. The indicator lights 222 include a power light, a high liquid level light, a low liquid level light, and a wireless indicator light; the indicator lights 222 provide a clear view of the liquid level and operating status inside the transfer box 3.

[0048] An alarm 211, electrically connected to the controller 5, is also installed on the side wall of the tank 21. The alarm 211 is a buzzer alarm. When an abnormal situation occurs in the system, such as when the liquid level is too low, the low liquid level gauge 31 sends a signal to the controller 5. The controller 5 controls the low liquid level light to turn on and simultaneously controls the transfer pump 4 to start, pumping the fuel in the storage tank 1 into the transfer tank 3. If no fuel enters the transfer tank 3 within the set time, it means that the fuel in the storage tank 1 is exhausted. At this time, the controller 5 controls the alarm 211 to emit an audible and visual signal to promptly remind the operator to shut down the control box 2 and replace the storage tank 1 with a new one.

[0049] This embodiment provides a buffer for fuel supply by setting up a control box 2 and a transfer box 3 within it. For example, when the fuel demand at the combustion end suddenly increases, the transfer box 3 can quickly supply fuel to the combustion end, avoiding flame instability or flameout caused by the untimely response of the storage tank 1, thus effectively ensuring a stable fuel supply. Furthermore, by setting up components such as the controller 5, level gauge, and indicator light 222, the intelligence of the alcohol-based fuel supply and the safety of its use are improved.

[0050] Example 2

[0051] The difference between this embodiment and Embodiment 1 is that, as Figure 4As shown, the storage tank 1 includes a base 11, a tank body 10, and a guardrail plate 12 disposed on the top of the tank body 10. The tank body 10 also has multiple outwardly protruding annular anti-collision strips 101. Specifically, the tank body 10 has annular grooves, and the annular anti-collision strips 101 are rubber rings that protrude from the surface of the tank body 10 after installation. This reduces the risk of direct collisions between storage tanks 1 and between storage tanks 1 and other equipment during transportation. Furthermore, when the storage tank 1 falls over, the protruding annular anti-collision strips 101 also provide some protection for the tank body 10, preventing it from directly impacting the ground.

[0052] In this embodiment, the fence panel 12 has an arc-shaped structure, with rolled edges on the top and sides. A handrail opening 121 is also provided on the fence panel 12, and the gripping portion of the handrail opening 121 has a widened portion 122. Specifically, the widened portion 122 can be an integral structure with the fence panel 12, and the widened portion 122 is bent inward into an arc shape. For example, when processing the handrail opening 121, a baffle is left in the handrail opening 121, and the baffle is bent inward into an arc-shaped widened portion 122, which facilitates processing and shaping. In other embodiments besides this one, the widened portion 122 can also be formed separately from the fence panel 12. For example, the widened portion 122 can be welded to the upper and lower gripping portions of the handrail opening 121, and the upper and lower parts of the widened portion 122 can be rolled inward for easy gripping.

[0053] The top of the tank 10 is also equipped with an inlet / outlet 102 and a vent 103, with an inlet one-way valve installed in the vent 103. The inlet / outlet 102 can be used to inject alcohol-based fuel into the tank 10 and also serves as an outlet connected to the transfer box 3 via a pipeline. More preferably, the tank 10 is also equipped with a pressure relief valve (not shown in the figure). During transportation, the liquid inside the tank 10 may slosh, leading to increased pressure. By installing a pressure relief valve, the pressure can be automatically released when the pressure becomes too high, improving safety during use.

[0054] In this embodiment, the ventilation port 103 facilitates pressure balance. As fuel is output, the space inside the tank gradually increases, creating a certain degree of vacuum, which makes it difficult for fuel to flow out smoothly. The ventilation port 103 allows air to enter the tank in time, breaking the vacuum and preventing air blockage, ensuring that the fuel can flow out smoothly from the inlet / outlet 102 for normal use. On the other hand, after filling, inert gas can be injected into the tank 10 through the ventilation port 103 to form a gas film, which provides a certain degree of protection for the alcohol-based fuel.

[0055] Example 3

[0056] The difference between this embodiment and Embodiment 1 or 2 is that the controller 5 is wirelessly connected to the user terminal; the user terminal includes mobile phones, computers, etc. In actual use, operators can remotely operate the controller 5 on the user terminal and flexibly adjust the system's operation according to actual needs. For example, in case of an emergency, operators do not need to go to the site; they can remotely control the start and stop of the delivery pump 4, close relevant valves, etc., through the user terminal to prevent the occurrence or escalation of safety accidents and ensure the safety of the system and personnel. In addition, when a safety accident occurs, the controller 5 can also promptly send accident information to the user terminal, fire department, or management personnel terminal to achieve timely and intelligent notification.

[0057] The above are merely embodiments of this utility model, and the utility model is not limited to the field covered by this embodiment. Commonly known structures and characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
