Description

Technical Field

[0001] This utility model belongs to the technical field of air storage cylinder equipment for heavy-duty mining trucks, and particularly relates to an integrated air storage cylinder for heavy-duty mining trucks. Technical Background

[0002] In metallurgical mining operations, heavy-duty mining dump trucks bear the heavy responsibility of transporting ore and waste rock, and their safe and stable operation is crucial for efficient mine production. As a core component of the vehicle's air system, the air reservoir has functions such as storing, stabilizing, purifying compressed air, and providing emergency air supply, directly affecting the performance of critical systems such as the electrical system. Currently, to ensure the dryness and cleanliness of compressed air in the air system, the industry generally adopts an integrated design scheme combining an oil-water separator, dryer, and air reservoir for compressed air dehumidification. However, this solution has revealed several shortcomings in practical applications: First, the integration of multiple components leads to structural complexity, increasing not only the cost of spare parts procurement and the difficulty of warehousing management but also the required installation space; second, maintenance requires the disassembly of multiple related components, making repair procedures cumbersome and time-consuming, significantly reducing vehicle availability; third, limited by existing drying technology, the system's dehumidification effect is difficult to meet actual needs under the harsh conditions of high humidity and high dust in mines, and residual moisture easily enters the air system. Especially in cold northern regions, freezing moisture in low temperatures can cause air circuit components to malfunction, leading to vehicle breakdowns and posing a threat to safe production. Furthermore, the high costs associated with frequent replacement of drying components further restrict the economic efficiency and reliability of heavy-duty mining dump trucks. Utility Model Content

[0003] The purpose of this invention is to provide an integrated air storage cylinder for heavy-duty mining trucks that is compact in structure, highly efficient in dehumidification, and easy to maintain.

[0004] The objective of this utility model is achieved through the following technical solution: This utility model discloses an integrated air storage cylinder for heavy-duty mining trucks, comprising an air storage cylinder body, an inlet one-way valve, a pressure gauge, a safety valve, an outlet one-way valve, a pressure regulating valve, and a clamp. The inlet one-way valve is located at the left end of the air storage cylinder body, while the pressure gauge, safety valve, and outlet one-way valve are located at the upper part of the air storage cylinder body. The pressure regulating valve is located at the right end of the air storage cylinder body. Two clamps are respectively located on the outer sides of the air storage cylinder body. The invention is characterized by: an electric cooling plate, a temperature control switch, and a power supply A being provided at the upper part of the air storage cylinder body. The switch is electrically connected to the electric cooling plate and power supply A respectively; three sets of radiators are provided at intervals on the outside of the gas storage cylinder body; inside the gas storage cylinder body, the lower condenser plate A, the upper condenser plate A, the lower condenser plate B, and the upper condenser plate B are alternately arranged at intervals. The upper ends of the upper condenser plate A and the upper condenser plate B are located away from the top of the gas storage cylinder body, and the lower ends of the lower condenser plate A and the lower condenser plate B are located away from the bottom of the gas storage cylinder body, forming a serpentine gas channel. A return hole is opened between the lower part of the lower condenser plate A and the lower condenser plate B and the gas storage cylinder body.

[0005] As a further description of the above technical solution: an electric heating pressure drain valve and a power supply B are provided in the lower right part of the cylinder body of the air cylinder. The pressure regulating valve is connected to the electric heating pressure drain valve by a pipeline, and the electric heating pressure drain valve is connected to the power supply B.

[0006] Compared with the prior art, the beneficial effects of this utility model are: This invention combines the forced cooling of an electric cooling plate, the deflection and condensation of a condenser plate, and the natural heat dissipation of a radiator into a three-in-one system. This eliminates the need for an oil-water separator and dryer in the air system, using a single "integrated air storage cylinder for heavy-duty mining trucks" to dehumidify compressed air. This solves the problems of low dehumidification efficiency, high spare parts consumption, and difficult maintenance associated with previous technologies. It effectively prevents damage and failure of air system components, as well as air system freezing, caused by moisture in the compressed air. This reduces equipment failure rates and labor intensity, saves spare parts costs, and improves vehicle operating efficiency. Attached Figure Description

[0009] The present invention will be further described below with reference to the accompanying drawings.

[0010] like Figure 1 and Figure 2As shown, this utility model discloses an integrated air storage cylinder for heavy-duty mining vehicles, comprising an air storage cylinder body 1, an inlet one-way valve 2, a pressure gauge 4, a safety valve 8, an outlet one-way valve 9, a pressure regulating valve 10, and a retaining strap 11. The inlet one-way valve 2 is located at the left end of the air storage cylinder body 1, the pressure gauge 4, the safety valve 8, and the outlet one-way valve 9 are located at the upper part of the air storage cylinder body 1, the pressure regulating valve 10 is located at the right end of the air storage cylinder body 1, and two retaining straps 11 are respectively located on the outer sides of the air storage cylinder body 1. The invention is characterized by: an electric cooling plate 5, a temperature control switch 6, and a power supply A7 being provided at the upper part of the air storage cylinder body 1. The valve 6 is electrically connected to the electric cooling plate 5 and the power supply A7 respectively; three sets of radiators 3 are provided at intervals on the outside of the gas storage cylinder body 1; inside the gas storage cylinder body 1, the lower condenser plate A15, the upper condenser plate A15, the lower condenser plate B16, and the upper condenser plate B17 are alternately arranged at intervals. The upper ends of the upper condenser plate A15 and the upper condenser plate B17 are located away from the top of the gas storage cylinder body 1, and the lower ends of the lower condenser plate A14 and the lower condenser plate B16 are located away from the bottom of the gas storage cylinder body 1, forming a serpentine gas channel. A return hole 18 is opened between the lower part of the lower condenser plate A14 and the lower condenser plate B16 and the gas storage cylinder body.

[0011] As a further description of the above technical solution: an electric heating pressure drain valve 13 and a power supply B12 are provided in the lower right part of the cylinder body 1 of the air cylinder. The pressure regulating valve 10 is connected to the electric heating pressure drain valve 13 by a pipeline, and the electric heating pressure drain valve 13 is connected to the power supply B12.

[0012] The working principle of this utility model: 1. Secure the air storage cylinder body 1 to the car frame using the clamp 11.

[0013] 2. Install the intake check valve 2, radiator 3, pressure gauge 4, electric cooling plate 5, temperature control switch 6, safety valve 8, exhaust check valve 9, and electric heating pressure drain valve 13 on the outside of the air storage cylinder body 1.

[0014] 3. Then, install the upper condenser plate A15 and upper condenser plate B17, and the lower condenser plate A14 and lower condenser plate B16 inside the gas storage cylinder body 1 respectively. A return hole 18 is opened between the lower part of the lower condenser plate A14 and lower condenser plate B16 and the gas storage cylinder body.

[0015] 4. Temperature control switch 6 is connected to electric cooling plate 5 and power supply A7 respectively. When the gas temperature in the cylinder body 1 of the gas storage cylinder is higher than the set value, temperature control switch 6 connects the circuit of electric cooling plate 5 and power supply A7, and electric cooling plate 5 works; when the gas temperature in the cylinder body 1 of the gas storage cylinder is lower than the set value, temperature control switch 6 does not operate, electric cooling plate 5 and power supply A7 are in the open circuit state, and electric cooling plate 5 does not work.

[0016] 5. Compressed air enters the air storage cylinder body 1 through the intake check valve 2, passes through the lower condenser plate A14, upper condenser plate A15, lower condenser plate B16 and upper condenser plate B17, and is blocked from condensation. The pressure is monitored by the pressure gauge 4, and the safety valve 8 prevents the air pressure from being too high. Finally, the dry gas is discharged through the outlet check valve 9 and enters the air circuit components of the air circuit system. The compressed air is forced to cool by the electric cooling plate 5 and blocked from condensation by the four condenser plates. Combined with the natural heat dissipation of the radiator, the condensate from the compressed air flows through the return hole A18 to the electric heating pressure drain valve 13 at the bottom of the air storage cylinder body 1.

[0017] 6. When the pressure setting value of the air storage cylinder body 1 is higher than the setting value of the pressure regulating valve 10, the pressure regulating valve 10 works, and the airflow reaches the electric heating pressure drain valve 13. The electric heating pressure drain valve 13 works under gas pressure to remove moisture from the air storage cylinder body 1 and keep the compressed air in the air storage cylinder body 1 dry and clean.

[0018] This device combines three functions—forced cooling by an electric cooling plate, condensation by a condensing plate, and natural heat dissipation by a radiator—to replace the traditional multi-component dehumidification structure. While simplifying the air path system, it significantly improves the dehumidification effect of compressed air. It effectively prevents malfunctions such as freezing damage and jamming of air path components caused by residual moisture in the compressed air, reduces equipment maintenance frequency and personnel workload, lowers spare parts replacement costs, and improves the operational reliability and efficiency of heavy-duty mining dump trucks under complex working conditions.
