Description

Technical Field

[0001] This utility model relates to the field of refueling equipment technology, and in particular to an explosion-proof refueling system for mining. Background Technology

[0002] Mining areas are generally far from urban areas, making it relatively inconvenient to refuel mining equipment. Therefore, refueling trucks are used for refueling. These trucks are equipped with oil tanks, which typically store a specified amount of oil to refuel the equipment. For example, the mining area refueling truck disclosed in announcement number CN102795147A can transport large quantities of oil to the mining area to refuel the mining equipment.

[0003] Currently, oil tankers have separate tanks and refueling devices. The tank is only used for refueling, while the refueling device is mounted on the vehicle. This makes overall installation inconvenient, requiring separate installation of the tank and refueling device, increasing the installation process. Furthermore, during transportation, the internal temperature and pressure of the tank can change depending on the working environment. Excessive pressure could pose a risk of tank explosion. Utility Model Content

[0004] The purpose of this invention is to provide a mine explosion-proof refueling system that is easy to install and can adaptively adjust the pressure of the oil tank.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] A mining explosion-proof refueling system, reference Figures 1-5 It includes oil tank 1, which has a square-round structure with oblong ends. The interior of oil tank 1 is divided into independent oil compartment 2 and equipment compartment 3 by a corrugated partition 14.

[0028] Equipment compartment 3 has doors on three sides, with two curved doors along the tank body on the sides. The oil tank 1 has door frames embedded in its head, providing double doors. Each door is equipped with a lock for easy opening and closing. The tank body is welded from high-quality carbon structural steel. The tank body is bolted to the chassis frame of the transport vehicle via connecting seats 17 on the tank feet 16.

[0029] To facilitate personnel access to the tank for maintenance, an upper cover assembly 13 is provided on the upper part of the tank, above the oil tank 2. The upper cover assembly 13 is a European standard tank opening with a breather valve, including the upper cover and the bolts that fix the upper cover. By loosening the bolts of the upper cover retaining ring and removing the retaining ring, the upper cover can be removed to check the oil in the tank and to fill the tank with oil.

[0030] During use, the breather valve can automatically adjust the internal and external pressure of oil tank 1 to achieve a balance between the internal and external pressures. When the tank is tilted, the breather valve will automatically close to effectively prevent oil leakage. When the external temperature of the tank is too high and the internal pressure increases, the exhaust device will open to release the internal pressure and effectively prevent an explosion.

[0031] The equipment compartment 3 is equipped with refueling equipment, including a first three-way ball valve 4, a filter 8, an oil pump 9, and a refueling nozzle 12. The first three-way ball valve 4 has three connection ports. One connection port is connected to an oil outlet pipe 5, which passes through a partition 14 and connects to the oil tank 2. Another connection port is connected to a refueling pipe port 6, which is equipped with a quick connector for quick connection to an external oil supply device to refuel the oil tank 1. A third connection port is connected to an oil delivery pipe 7, which is equipped with a filter 8, an oil pump 9, a pressure gauge 23, and a flow meter 24. A second three-way ball valve 10 is then connected to the oil delivery pipe 10. The second three-way ball valve 10 has three connection ports. Of the other two connection ports, one is connected to the refueling nozzle 12 for refueling other machinery and equipment, and the other is connected to an oil inlet pipe 11, which also passes through a partition 14 and connects to the oil tank 2.

[0032] Among them, the first three-way ball valve 4 and the second three-way ball valve 10 are both three-position four-way ball valves with T-type structure.

[0033] The filter 8 is a protective device for the oil pump 9 and the flow meter 24. It can filter out impurities and dirt in the oil to prevent them from entering the flow meter 24 and damaging its components. At the same time, the filter 8 is also the last stage of filtration at the oil outlet, which can effectively ensure the cleanliness of the separated oil.

[0034] A fuel nozzle 12 is connected to a fuel delivery hose and a reel 28 between it and the second three-way ball valve 10. The reel 28 can be used to wind up the fuel delivery hose. When refueling, the fuel nozzle 12 can be pulled to extend the refueling distance of the fuel nozzle 12.

[0035] The working process of the above refueling system is as follows:

[0036] 1. The first three-way ball valve 4 closes the oil delivery pipe 7. At this time, the oil tank 1, the oil outlet pipe 5 and the refueling port 6 are connected. The oil in the oil tank 1 can flow out from the oil outlet pipe 5 and the refueling port 6, realizing the gravity flow of oil from the tank.

[0037] 2. The first three-way ball valve 4 closes one side of the refueling pipe port 6, connecting the oil outlet pipe 5 and the oil delivery pipe 7. The second three-way ball valve 10 closes one end of the oil inlet pipe 11, connecting the oil delivery pipe 7 and the refueling nozzle 12. The oil pump 9 is turned on, and the diesel fuel in the tank can be injected from the refueling nozzle 12 into other containers for refueling other machinery and equipment.

[0038] 3. The first three-way ball valve 4 closes one side of the oil outlet pipe 5, and connects the oil filling port 6 and the oil supply pipe 7. The second three-way ball valve 10 closes one end of the oil filling gun 12, and connects the oil supply pipe 7 and the oil inlet pipe 11. Connect the oil filling port 6 to the external oil supply equipment and turn on the oil pump 9 to realize the filling of oil into the oil tank 1.

[0039] Furthermore, in the above structure, the oil pump 9 is a gear pump, and the oil pump 9 has a built-in overflow valve 25. In this embodiment, the oil pump 9 is selected from the CBZ2 series high-pressure gear pump, which adopts axial compensation and radial tracking compensation, and can adapt to low speed and high speed. The oil pump 9 is driven by the hydraulic motor 18 and the hydraulic system. The hydraulic motor 18 is connected to the speed regulating valve 27. The output end of the hydraulic motor 18 and the input end of the gear pump are connected through a transmission mechanism. In this embodiment, the transmission mechanism is a coupling. In other embodiments, the transmission mechanism can be a gear set or other mechanisms with the same transmission effect.

[0040] The hydraulic system that ensures the normal operation of the hydraulic motor 18 is powered by the vehicle chassis and drives the hydraulic motor 18 through hydraulic pipelines. This is a standard setup in the field and will not be described in detail here.

[0041] In the equipment compartment 3, a bracket 19 is also provided for fixing the oil pump 9 and the hydraulic motor 18. The bracket 19 specifically includes a base plate 20 fixedly connected to the oil tank 1. The oil pump 9 is fixedly connected to the base plate 20. Connecting plates 21 are fixedly provided on both sides of the base plate 20. A mounting plate 22 is fixedly provided at one end of the connecting plate 21. The hydraulic motor 18 is fixedly connected to the mounting plate 22. A protective plate 26 is provided above the two connecting plates 21. The protective plate can protect the transmission mechanism.

[0042] In other embodiments, the bracket 19 can be other structures that can fix the oil pump 9 and the hydraulic motor 18.

[0043] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
