Description

Technical Field

[0001] This utility model relates to the field of water supply vehicle technology, specifically to an air intake pipe structure for a water supply semi-trailer. Background Technology

[0002] Before filling the water supply semi-trailer with high-temperature steam (300℃), the tanker already contains approximately 60% of its volume of saturated water at 150℃. The commonly used intake pipe structure is: quick-connect coupling → electric ball valve → check valve → manual ball valve → a pipe extending to the bottom of the tank. The internal pipe is sealed at the end, with several vent holes drilled in it to facilitate heat exchange between the high-temperature steam and the water. This structure generates significant noise and easily causes the vehicle to shake when filling with high-temperature, high-pressure steam. The heat exchange efficiency between steam and water is relatively low, resulting in a longer time for the saturated water inside the tank to reach 236℃. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide an intake pipe structure that is low in noise, stable during filling, and has high efficiency in steam and water heat exchange.

[0004] To achieve the above objectives, the technical solution of this utility model is: an air intake pipe structure for a water supply semi-trailer, comprising an air intake pipe installed outside the tank and a heat exchange pipe installed inside the tank, wherein the air intake pipe and the heat exchange pipe are connected, characterized in that: a silencer mixer connected to the inside of the heat exchange pipe is installed on the heat exchange pipe, the silencer mixer comprising an inner cylinder and an outer cylinder, the outer cylinder being sleeved outside the inner cylinder, and an upper cover plate and a lower cover plate respectively provided at the upper and lower ends of the outer cylinder, wherein a plurality of exhaust holes are evenly arranged on the cylinder walls of the inner and outer cylinders, and the inner cylinder is connected to the inside of the heat exchange pipe.

[0005] The air intake pipe is equipped with a quick connector at the air inlet, and an electric ball valve, a check valve, and a manual ball valve are installed on the air intake pipe.

[0006] The air intake pipe is equipped with a structure consisting of elbows to prevent thermal expansion and contraction.

[0007] The inner cylinder is made of φ76 steel pipe, and the outer cylinder is made of φ160 steel pipe.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model significantly reduces noise during inflation by installing a silencer mixer with vent holes on the heat exchange pipe. The symmetrical opening design of the silencer mixer counteracts the reaction force of the gas during inflation, making the inflation of the vehicle body very smooth. Multiple silencers are distributed inside the tank, and high-temperature steam is sprayed out in all directions through the vent holes of the silencer outer cylinder, fully exchanging heat with water, improving the heat exchange rate and shortening the inflation time.

[0009] 2. The three valves—electric ball valve, check valve, and manual ball valve—installed on the air intake pipe in this utility model can ensure that the air supply can be cut off in case of an emergency during filling of the semi-trailer, thus preventing overpressure of the tank.

[0010] 3. The thermal expansion and contraction prevention structure formed by the elbow in this utility model can effectively prevent thermal expansion and contraction from damaging the pipeline structure. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] See Figures 1-4 A water supply semi-trailer air intake pipeline structure includes an air intake pipe 1 installed outside the tank and a heat exchange pipe 2 installed inside the tank. The air intake pipe 1 and the heat exchange pipe 2 are connected. A quick connector 9 is provided at the air inlet of the air intake pipe 1. An electric ball valve 10, a one-way valve 11, and a manual ball valve 12 are installed on the air intake pipe 1. The air intake pipe 1 is provided with a structure to prevent thermal expansion and contraction formed by elbows 13. Multiple silencers 3 connected to the inside of the heat exchange pipe 2 are installed on the heat exchange pipe 2. The silencer 3 includes an inner cylinder 4 and an outer cylinder 5. The outer cylinder 5 is sleeved on the outside of the inner cylinder 4. The inner cylinder 4 is made of φ76 steel pipe, and the outer cylinder 5 is made of φ160 steel pipe. An upper cover plate 6 and a lower cover plate 7 are respectively provided at the upper and lower ends of the outer cylinder 5. A number of exhaust holes 8 are evenly arranged on the cylinder walls of the inner cylinder 4 and the outer cylinder 5. The inner cylinder 4 is connected to the inside of the heat exchange pipe 2.

[0018] The working process of this utility model is as follows: First, the external 300℃ high temperature and high pressure gas source is connected to the quick connector 9 through a hose. The electric ball valve 10 and the manual ball valve 12 are opened. After the gas passes through the air inlet pipe 1 and the heat exchange pipe 2, it finally flows to the silencer mixer 3. Then, the high temperature and high pressure steam is discharged to the surroundings through the exhaust port 8 on the silencer mixer 3. The steam fully exchanges heat with the 150℃ saturated water stored in the tank. Finally, the temperature of the saturated water reaches about 236℃. Then, the electric ball valve 10 is closed, and the filling is completed.
