Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model discloses a small pressure swing adsorption skid-mounted device that is easy to assemble, including a support base 1. Both sides of the outer wall of the two support bases 1 are fixedly connected to side connecting bases 2 by side fixing rods 11. The top of the two side connecting bases 2 is fixedly connected to spring terminals 3, and the bottom of the two spring terminals 3 is fixedly connected to support feet 4.

[0023] Side brackets 5 are fixedly connected to both sides of the top of the support base 1, bottom support frames 6 are fixedly connected to the bottom of the two side brackets 5, and circuit connection boards 7 are fixedly connected to one side of the two side brackets 5.

[0024] Specifically, this small-scale pressure swing adsorption skid-mounted equipment uses a support base 1 as its basic load-bearing structure. Side fixing rods 11, side connecting seats 2, spring terminals 3, and support legs 4 constitute the equipment's stable support and vibration damping structure. Side brackets 5 and bottom support frames 6 are used for auxiliary support and stabilization. Circuit connection plates 7, connecting frames 8, and terminal blocks 9 form a well-organized circuit connection system. The transformer 10, as a core component, along with a heat sink 12, cooling fan 14, and guide fan 18, constitutes a high-efficiency heat dissipation system. Through reasonable design and layout, each component enables convenient assembly, stable operation, and efficient heat dissipation, meeting the gas separation requirements of various scenarios. The support base 1 is made of high-strength aluminum alloy, and the side fixing rods 11 are made of stainless steel. Both ends are fixedly connected to the outer wall of the support base 1 and the side connecting seats 2 by bolts, serving a connecting and reinforcing function. The side connecting seats 2 are also made of aluminum alloy and, after being connected to the support base 1 via the side fixing rods 11, form a stable frame structure for the equipment. Other components provide the mounting base. The spring terminal 3 is made of high-strength spring steel and undergoes heat treatment to ensure a stable elastic coefficient, effectively buffering vibrations during equipment operation. One end of the spring terminal 3 is fixedly connected to the top of the side connecting seat 2, and the other end is fixedly connected to the support leg 4. The support leg 4 is made of rubber with anti-slip textures on the bottom, which not only increases the friction between the equipment and the ground to prevent the equipment from sliding, but also further absorbs vibrations and reduces the impact of the equipment on the ground during operation. Through the cooperation of the spring terminal 3 and the support leg 4, the vibration amplitude during equipment operation can be reduced, effectively protecting the internal components of the equipment and extending its service life. The side bracket 5 is fixedly connected to both sides of the top of the support seat 1. It is made of aluminum alloy profile and is connected to the support seat 1 through welding, providing good rigidity. The bottom support frame 6 is fixed to the bottom of the side bracket 5. It adopts a triangular structure design and is welded from stainless steel pipes, which can enhance the overall stability of the equipment and prevent the equipment from shaking during operation.

[0025] In this embodiment, the top of the support base 1 is fixedly connected to the transformer 10 between the two side brackets 5, and heat dissipation boxes 12 are fixedly connected to both sides of the outer wall of the transformer 10.

[0026] Specifically, the transformer 10, as the core component of the equipment, is fixedly installed at the top of the support base 1 between the two side brackets 5, making the transformer 10 more securely fixed.

[0027] In this embodiment, the inner walls of both heat sinks 12 are provided with inner cavities 13, and cooling fans 14 are fixedly connected to the inner walls of both inner cavities 13.

[0028] Specifically, the heat sink 12 is fixed on both sides of the outer wall of the transformer 10. It is made of aluminum alloy and has good thermal conductivity. The inner cavity 13 opened in the inner wall of the heat sink 12 provides installation space for the cooling fan 14. The cooling fan 14 is a high-speed, low-noise axial fan, which is installed on the inner wall of the inner cavity 13. It draws in outside cold air and blows it onto the surface of the transformer 10 to accelerate heat dissipation. The partition 15 is fixed on one side of the outer wall of the heat sink 12, located on the side of the cooling fan 14. It plays a role in guiding the airflow direction so that the cold air can flow through the transformer 10 more effectively and improve the heat dissipation efficiency.

[0029] In this embodiment, a connecting block 17 is fixedly connected to the top of the heat sink 12, and a guide fan 18 is fixedly connected to both sides of the connecting block 17.

[0030] Specifically, the connecting block 17 is fixed to the top of the heat sink 12 and is made of aluminum alloy. It is used to install the guide fan 18. The guide fan 18 is a small centrifugal fan, which can quickly guide the hot air blown out by the heat sink 14 to the outside of the equipment, further enhancing the heat dissipation effect.

[0031] In this embodiment, a top controller 16 is fixedly connected to the top of the heat sink 12 on the outer wall of the cooling fan 14, and the top controller 16 is located on both sides of the transformer 10.

[0032] Specifically, the top controller 16 is fixed to the top of the heat sink 12 and located on the outer wall of the cooling fan 14. Operators can monitor and adjust the equipment's operating status in real time through the top controller 16, such as controlling the speed of the cooling fan 14 and the guide fan 18, to ensure the safe and reliable operation of the equipment.

[0033] In this embodiment, a partition 15 is fixedly connected to one side of the outer wall of each of the two heat sinks 12, and both partitions 15 are located on one side of the cooling fan 14.

[0034] Specifically, by setting up partition 15, external dust is prevented from entering the device.

[0035] In this embodiment, multiple circuit connection boards 7 are fixedly connected to each other by a connection bracket 8, and a terminal block 9 is fixedly connected to one side of each of the multiple circuit connection boards 7.

[0036] Specifically, multiple circuit connection boards 7 are fixed on one side of the side bracket 5. They are made of epoxy resin board with good insulation properties and the surface is treated with anti-oxidation. The circuit connection boards 7 are pre-set with standardized circuit interfaces and mounting holes to facilitate the installation and connection of circuit components. The connection frame 8 is made of stainless steel and is used to connect multiple circuit connection boards 7 to make the circuit connection more regular and facilitate wiring and maintenance. The terminal block 9 is fixed on one side of the circuit connection board 7 and has multiple terminals on it, which can realize the quick connection and disconnection of the circuit, greatly improving the efficiency of circuit assembly and maintenance.

[0037] The working principle and usage process of this utility model are as follows: When in use, after the equipment is assembled and connected to the power supply, the transformer 10 starts working, converting the input voltage into the voltage required for the equipment to operate. The top controller 16 starts and displays the equipment operating parameters in real time, such as voltage, current, and temperature. The cooling fan 14 starts under the control of the top controller 16, drawing in cold air from the outside and blowing it onto the surface of the transformer 10, carrying away the heat generated during the operation of the transformer 10. After flowing through the transformer 10, the cold air becomes hot air and is quickly guided to the outside of the equipment by the guide fan 18, achieving effective heat dissipation inside the equipment. At the same time, the circuit system, under the action of the terminal block 9 and the circuit connection board 7, stably transmits power, driving the internal voltage transformer adsorption system of the equipment to work, realizing the separation and purification of the mixed gas. During the operation of the equipment, the spring terminal 3 and the support leg 4 effectively buffer the vibration generated by the operation of the equipment, ensuring stable operation of the equipment.
