Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive air reservoir. Background Technology

[0002] Early automotive braking systems were relatively simple. However, as vehicle speeds and loads increased, the requirements for the reliability and stability of braking systems became increasingly stringent. Air reservoirs, as gas storage devices in automotive braking systems, store gas compressed by the air compressor, providing a stable air supply for braking. Air reservoirs with a single inlet and outlet had poor pressure stabilization, leading to the development of air reservoirs with a single inlet and outlet design. This resulted in a more stable output of compressed air, better meeting the pressure requirements of the braking system. Simultaneously, to cope with different road conditions and braking demands, the capacity and pressure resistance of air reservoirs have been continuously improved.

[0003] In automotive air tanks, a single purification structure is insufficient to effectively purify the gas, often leading to equipment malfunction and damage due to impurities and moisture within the gas. Utility Model Content

[0004] The purpose of this invention is to provide an automotive air tank that divides the air tank into a first chamber and a second chamber by a partition, thereby achieving phased gas processing. This phased processing method can significantly improve the degree of gas purification, providing cleaner and drier gas for subsequent gas-using equipment and reducing equipment failures and damage caused by gas impurities and moisture.

[0005] To achieve the above objectives, a vehicle air reservoir is provided, comprising: an air reservoir, a partition fixedly connected to the inner surface of the air reservoir, a connecting pipe fixedly connected inside the partition, a first check valve and a second check valve respectively provided on the left and right sides of the connecting pipe, and a second cavity provided on one side of the connecting pipe, the interior of which is filled with activated alumina absorbent material.

An air pressure gauge is installed on the upper surface of the air inlet pipe. The air inlet pipe communicates with the first cavity, and the air pressure gauge monitors and ensures a stable flow of gas into the reservoir.

[0010] According to the aforementioned automotive air reservoir, a second chamber pressure gauge is provided on the front surface of the second chamber, and a second water outlet is provided on the lower surface of the second chamber. The second chamber pressure gauge monitors the air pressure, and the water outlet drains water to ensure the second chamber functions properly.

[0011] According to the aforementioned automotive air reservoir, an air outlet pipe is fixedly connected to the end of the air reservoir away from the air inlet pipe, and the interior of the air outlet pipe is connected to the interior of a second chamber.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model discloses an automotive air tank, comprising: an air tank 1, with a partition 17 fixedly connected to the inner surface of the air tank 1, dividing the interior of the air tank 1 into two relatively independent spaces, providing a basis for different gas processing processes and ensuring the stable operation of each functional area; a connecting pipe 18 fixedly connected inside the partition 17, serving as a channel for gas flow between a first cavity 13 and a second cavity 14, allowing gas to be transported orderly between the two cavities to complete subsequent processing steps; a first check valve 15 and a second check valve 16 are respectively provided on the left and right sides of the connecting pipe 18. The valve 16 works together to prevent gas backflow, ensuring that the gas can only flow from the first chamber 13 through the connecting pipe 18 to the second chamber 14 in a predetermined direction, maintaining the unidirectionality of the gas treatment process. The second chamber 14 is provided on one side of the connecting pipe 18, providing space for further gas treatment. It works in conjunction with the first chamber 13 to form a complete gas treatment chain. The interior of the second chamber 14 is provided with activated alumina absorbent material 7, which can deeply dry and adsorb impurities in the gas entering the second chamber 14. It works synergistically with the molecular sieve absorbent material 3 in the first chamber 13 to improve the degree of gas purification.

[0025] The first check valve 15 is located inside the second cavity 14. Its position ensures that the gas entering the second cavity 14 from the first cavity 13 is effectively controlled when passing through the connecting pipe 18, preventing gas from flowing back into the first cavity 13. The activated alumina absorbent material 7 is located at the bottom of the inner surface of the second cavity 14. This arrangement allows the gas to fully contact the activated alumina absorbent material 7 after entering the second cavity 14, improving absorption efficiency and ensuring the drying and purification effect of the gas. The first cavity 13 is located on the side of the partition 17 away from the second cavity 14. The first cavity 13 serves as the first processing space after the gas enters the gas storage tank 1. It works in conjunction with the second cavity 14 to initially treat impurities and moisture in the gas. The first check valve 15 is located inside the first cavity 13. Its position within the first cavity 13 is beneficial for controlling the flow from the first cavity 13 to the connecting pipe 18. The gas in the pipe 18 is precisely controlled to ensure the accuracy of the gas flow direction. A first chamber pressure gauge 4 is installed on the front surface of the first chamber 13. The first chamber pressure gauge 4 monitors the gas pressure in the first chamber 13 in real time, providing pressure data for operators to adjust the air intake in a timely manner or to determine if there is any abnormality in the chamber. A first water outlet 2 is installed on the lower surface of the first chamber 13. The first water outlet 2 is used to discharge the water separated after being treated by the molecular sieve absorbent material 3 in the first chamber 13, ensuring a dry environment in the first chamber 13 and maintaining the gas treatment effect. Molecular sieve absorbent material 3 is installed at the bottom of the inner surface of the first chamber 13. The molecular sieve absorbent material 3 can perform preliminary drying and impurity filtration on the gas entering the first chamber 13. In conjunction with the activated alumina absorbent material 7 in the second chamber 14, the gas is purified in stages.

[0026] An air inlet pipe 8 is fixedly connected to one side of the gas storage tank 1, and the air inlet pipe 8 is connected to the interior of the first cavity 13. The air inlet pipe 8 serves as the inlet for gas to enter the gas storage tank 1, introducing external gas into the first cavity 13 to start the gas treatment process. An air pressure gauge 9 is installed on the upper surface of the air inlet pipe 8, which monitors the gas pressure entering the gas storage tank 1 in real time, providing a basis for operators to adjust the air intake equipment and ensuring that the gas pressure entering the gas storage tank 1 is stable. A second chamber pressure gauge 6 is installed on the front surface of the second cavity 14, which monitors the gas pressure inside the second cavity 14 in real time, helping operators to understand the gas pressure changes after the gas has been processed by the second cavity 14 and to determine whether the treatment process is normal. A second water outlet 5 is installed on the lower surface of the second cavity 14, which is used to discharge water from the second cavity 14. The moisture separated after treatment with activated alumina absorbent material 7 keeps the second chamber 14 dry, ensuring the quality of gas treatment. The end of the gas storage tank 1 away from the inlet pipe 8 is fixedly connected to the outlet pipe 10, and the interior of the outlet pipe 10 is connected to the interior of the second chamber 14. The outlet pipe 10 serves as the outlet of the treated gas, delivering the clean gas treated by the first chamber 13 and the second chamber 14 to the subsequent equipment. An outlet pressure gauge 11 is installed on the upper surface of the outlet pipe 10, which monitors the gas pressure output from the gas storage tank 1 in real time to ensure that the gas pressure of the output gas meets the usage requirements of the subsequent equipment. A connector 12 is installed at the end of the outlet pipe 10 away from the gas storage tank 1. The connector 12 is used to connect the outlet pipe 10 to the subsequent gas-using equipment to achieve effective delivery and utilization of the treated gas.

[0027] Working principle: First, external gas enters the first chamber 13 of the gas storage tank 1 through the inlet pipe 8. At this time, the inlet pressure can be monitored in real time by the inlet pressure gauge 9 to ensure the stability of the inlet pressure. The gas entering the first chamber 13 first comes into contact with the molecular sieve absorbent material 3 at the bottom of the inner surface. The molecular sieve absorbent material 3 performs preliminary drying and impurity filtration on the gas. The separated water will be deposited at the bottom of the first chamber 13 and can be discharged through the first outlet 2. At the same time, the first chamber pressure gauge 4 will display the gas pressure in the first chamber 13 in real time. The gas that has been preliminarily treated in the first chamber 13 flows to the second chamber 14 through the connecting pipe 18 under the control of the first check valve 15. The first check valve 15 and the first... Two check valves 16 work together to ensure that the gas can only flow in one direction and prevent backflow. After the gas enters the second chamber 14, it comes into full contact with the activated alumina absorbent material 7 inside. The activated alumina absorbent material 7 performs deep drying and impurity adsorption on the gas. The separated water is deposited at the bottom of the second chamber 14 and can be discharged through the second outlet 5. The second chamber pressure gauge 6 displays the gas pressure in the second chamber 14 in real time. The clean gas after being treated by the two chambers is output through the gas outlet pipe 10. The gas outlet pressure gauge 11 monitors the gas pressure of the output gas in real time to ensure that it meets the requirements of the subsequent gas-using equipment. The gas outlet pipe 10 is connected to the subsequent gas-using equipment using the connector 12 so that the treated gas can be effectively utilized.
