Description

Technical Field

[0001] This utility model relates to the field of gasoline filling technology, specifically a gasoline filling machine for a general assembly workshop that reduces gasoline temperature and pressure. Background Technology

[0002] In the gasoline refueling process in the final assembly workshop, gasoline from the outdoor fuel station is transported to the refueling station via overhead gasoline pipelines laid on the plant's grid structure. In summer, due to the influence of roof heat radiation and the lack of cooling measures, the temperature in the upper part of the plant can reach as high as 45°C, causing the gasoline temperature in the overhead gasoline pipelines to rise.

[0003] The fuel tanks of China VI emission standard vehicles are not designed with vapor recovery and venting ports. When hot gasoline is added to the fuel tank of a commercial vehicle through a fuel dispenser, a large amount of vapor will evaporate due to pressure changes, causing the pressure inside the fuel tank to rise. This will trigger the fuel dispenser to trip and stop, affecting production efficiency.

[0004] Among the existing solutions, lowering the height of the overhead pipeline to the air-conditioning space under the factory building requires large-scale renovation, which is difficult and costly to implement; adding air conditioners around the overhead pipeline is costly and energy-intensive, both of which have obvious shortcomings. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a gasoline filling machine for assembly workshops that reduces gasoline temperature and pressure, solving the problem of excessively high gasoline temperature in the overhead gasoline pipelines of the assembly workshop during summer, which causes the pressure in the fuel tank to rise and the filling machine to trip when filling.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a gasoline filling machine for a general assembly workshop that reduces gasoline temperature and pressure, comprising a fuel filling machine, a stainless steel insulated chilled water tank, and a gasoline pipeline. The stainless steel insulated chilled water tank is connected to the chilled water supply system and the chilled water return system of the plant's air conditioning system, respectively. The gasoline pipeline is connected to the fuel filling machine via the stainless steel insulated chilled water tank, so that the gasoline exchanges heat with the chilled water in the stainless steel insulated chilled water tank.

[0007] Preferably, the gasoline pipeline includes an overhead gasoline pipeline in the plant, a gasoline pipeline inlet section in the chilled water tank, and a gasoline pipeline outlet section in the chilled water tank. The gasoline pipeline inlet section and the gasoline pipeline outlet section in the chilled water tank are respectively installed on both sides of the stainless steel insulated chilled water tank. The overhead gasoline pipeline in the plant is connected to the gasoline pipeline inlet section in the chilled water tank.

[0008] Preferably, the stainless steel insulated chilled water tank is provided with a drain outlet at the bottom.

[0009] Preferably, a water supply pipe is provided between the stainless steel insulated chilled water tank and the chilled water supply system for the factory air conditioning, and a return water pipe is provided between the stainless steel insulated chilled water tank and the chilled water return system for the factory air conditioning.

[0010] Preferably, the water supply pipe is equipped with a first valve, and the return water pipe is equipped with a second valve.

[0011] Preferably, both the first valve and the second valve are manual shut-off valves.

[0012] Preferably, the gasoline pipeline section leading to the chilled water tank is arranged in a curved shape within the stainless steel insulated chilled water tank.

[0013] Preferably, a sealing element is provided at the point where the gasoline pipeline passes through the stainless steel insulated chilled water tank.

[0014] Preferably, the drain outlet of the water tank is equipped with a sealing cap.

[0015] Its beneficial effects are as follows: 1. This gasoline dispenser in the assembly workshop, designed to reduce gasoline temperature and pressure, utilizes a stainless steel insulated chilled water tank to exchange heat with the gasoline entering the tank via the gasoline pipeline. This effectively lowers the gasoline temperature, reduces fuel vapor evaporation during dispensing, and prevents excessive pressure in the tank from causing the dispenser to trip, thus ensuring continuous production. No large-scale modifications to the plant or piping are required; only a stainless steel insulated chilled water tank needs to be added to the front of the dispenser and connected to the existing chilled water system of the plant's air conditioning system. The modification work is minimal, requires little space, and has low investment costs.

[0016] 2. The gasoline filling machine in the assembly workshop, which lowers gasoline temperature and pressure, has first and second valves on its water supply and return pipes that can be closed after summer to empty the stainless steel insulated chilled water tank. At this time, gasoline can still be normally delivered to the filling machine through the pipeline without needing to be cooled, adapting to different seasonal needs. The seals at the points where the gasoline pipeline passes through the stainless steel insulated chilled water tank, and the sealing cap at the tank's drain outlet, ensure the tank's airtightness and cleanliness, guaranteeing stable heat exchange. The curved arrangement of the gasoline pipeline entering the chilled water tank increases the heat exchange area and improves the cooling effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This utility model discloses a gasoline filling machine for a final assembly workshop that reduces gasoline temperature and pressure, according to the attached... Figure 1 As shown, it includes a fuel dispenser 8, a stainless steel insulated chilled water tank 7, and a gasoline pipeline. The stainless steel insulated chilled water tank 7 is connected to the chilled water supply system 3 and the chilled water return system 1 of the factory air conditioning system. The gasoline pipeline is connected to the fuel dispenser 8 through the stainless steel insulated chilled water tank 7, so that the gasoline can exchange heat with the chilled water in the stainless steel insulated chilled water tank 7.

[0023] The gasoline pipeline includes an overhead gasoline pipeline 2, a gasoline pipeline inlet section 4, and a gasoline pipeline outlet section 5. The gasoline pipeline inlet section 4 and the gasoline pipeline outlet section 5 are respectively installed on both sides of the stainless steel insulated chilled water tank 7. The overhead gasoline pipeline 2 is connected to the gasoline pipeline inlet section 4.

[0024] By exchanging heat between the chilled water in the stainless steel insulated chilled water tank 7 and the gasoline entering the chilled water tank section 4 through the gasoline pipeline, the gasoline temperature can be effectively reduced, minimizing fuel vapor evaporation during refueling and preventing excessive pressure in the fuel tank from causing the fuel dispenser 8 to trip and alarm, thus ensuring continuous production. No large-scale modifications to the plant or pipelines are required; only the stainless steel insulated chilled water tank 7 needs to be added before the fuel dispenser 8 and connected to the existing air conditioning chilled water system in the plant. The modification workload is small, the space required is minimal, and the investment cost is low.

[0025] The stainless steel insulated chilled water tank 7 has a drain outlet 6 at the bottom.

[0026] A water supply pipe 31 is installed between the stainless steel insulated chilled water tank 7 and the chilled water supply system 3 for the factory air conditioning system, and a return water pipe 11 is installed between the stainless steel insulated chilled water tank 7 and the chilled water return system 1 for the factory air conditioning system.

[0027] The water supply pipe 31 is equipped with a first valve, and the return water pipe 11 is equipped with a second valve.

[0028] Both the first and second valves are manual shut-off valves.

[0029] The gasoline pipeline entering the chilled water tank section 4 is arranged in a curved shape inside the stainless steel insulated chilled water tank 7.

[0030] The gasoline pipeline is fitted with a seal at the point where it passes through the stainless steel insulated chilled water tank 7.

[0031] The water tank drain outlet has six sealed caps.

[0032] The first and second valves on the water supply pipe 31 and the return pipe 11 can be closed after summer to empty the stainless steel insulated chilled water tank 7. At this time, gasoline can still be normally delivered to the fuel dispenser 8 through the pipeline without needing to be cooled, adapting to different seasonal needs. The seals at the points where the gasoline pipeline passes through the stainless steel insulated chilled water tank 7, and the sealing cap of the tank drain outlet 6, ensure the water tank's sealing and cleanliness, ensuring stable heat exchange. The curved arrangement of the gasoline pipeline entering the chilled water tank section 4 increases the heat exchange area and improves the cooling effect.

[0033] The stainless steel insulated chilled water tank 7 is connected to the chilled water supply system 3 of the plant's air conditioning system via a supply pipe 31, and to the chilled water return system 1 of the plant's air conditioning system via a return pipe 11, forming a chilled water circulation path. Gasoline flows into the chilled water tank section 4 via the overhead gasoline pipeline 2. In this section, the gasoline undergoes thorough heat exchange with the chilled water within the stainless steel insulated chilled water tank 7. The cooled gasoline then exits the chilled water tank section 5 via the gasoline pipeline and is delivered to the fuel dispenser 8 for refueling. After summer, the valves on the supply pipe 31 and the return pipe 11 are closed to drain the water from the tank. Gasoline can then be directly transported through the pipeline without affecting normal fuel supply. The tank drain outlet 6 allows for the periodic discharge of wastewater to maintain the cleanliness of the tank.
