Description

Technical Field

[0001] This invention relates to the field of buffer tank technology, specifically to a buffer tank device for a natural gas compressor. Background Technology

[0002] A buffer tank in a natural gas compressor is typically an accumulator used to balance the pressure difference between the inlet and outlet valves of the natural gas and to alleviate pressure pulsations generated during the operation of the natural gas compressor. Buffer tanks can help improve the stability and efficiency of the natural gas compressor and reduce equipment wear and failure rate.

[0003] However, existing natural gas compressor buffer tanks have some problems in use. They are usually installed on the ground, which results in a large footprint, affecting the placement of indoor space. They are also inconvenient to adjust the position of the buffer tank, reducing its applicability. In addition, vibration may occur during operation, which may cause the buffer tank to shift. Summary of the Invention

[0005] Preferably, the bottom of the two top plates is provided with a buffer tank body. L-shaped plates are fixedly connected to the front and rear sides of the buffer tank body near the left and right sides. A second flange is fixedly connected to the outer edge of the L-shaped plate away from the buffer tank body. The bottom of the elastic restraint band is attached to the top of the L-shaped plate. A first flange is fixedly connected to the outer edge of the elastic restraint band near the bottom. The first flange and the second flange are fitted together. Four second threaded holes are opened on the first flange and the second flange. A first bolt is threadedly connected to two adjacent second threaded holes.

Four third threaded holes are provided on both the fixed plate and the support ring. A second bolt is threadedly connected to two adjacent third threaded holes.

[0007] Preferably, two clamping plates are fitted to both the front and rear sides of the buffer tank body. A hinge is provided between the tops of two adjacent clamping plates, and the two adjacent clamping plates are hinged together. A support rod is fixedly connected to the side of the clamping plate away from the buffer tank body near the bottom. A limiting plate is fixedly connected to the end of the support rod away from the clamping plate. A second vibration damping pad is fixedly connected to the center of the bottom of the limiting plate.

[0008] Preferably, each of the clamping plates has a fifth threaded hole near the bottom of its inner cavity, and two adjacent fifth threaded holes are connected to a fourth bolt by a common thread. Each clamping plate is fixedly connected to a U-shaped block near the top on the side away from the buffer tank body. Each U-shaped block has a swing block hinged to its groove. Two swing blocks on the same side are fixedly connected to a limit rod at their tops. Each limit rod has a fixed post at its top center, and each fixed post has a first connecting plate fixedly connected to its top.

[0009] Preferably, L-shaped rods are fixedly connected to both the front and rear sides of the hydraulic cylinder near the bottom. A second connecting plate is fixedly connected to the end of the L-shaped rod away from the hydraulic cylinder. The bottom of the second connecting plate is attached to the top of the first connecting plate. A sixth threaded hole is opened on both the first and second connecting plates.

If the buffer tank body is working on the ground, the third bolt passes through the limiting plate and is rotated to the ground, thereby limiting the clamping plate and then limiting the buffer tank body. The first and second vibration damping pads can play a shock absorption and buffering role. To reduce the footprint of the buffer tank, the tank body is placed at the bottom of the horizontal plate. The first flange at the bottom of the elastic restraint strap is attached to the top of the second flange. The first and second flanges are connected by the first bolt. Then, the hydraulic cylinder drives the fixed plate, L-shaped rod, and second connecting plate to move downwards. The fixed plate and support ring are connected by the second bolt, and the first and second connecting plates are connected by the fifth bolt. The clamping plates are then connected. The hydraulic cylinder drives the buffer tank body to move up and down, thus moving the buffer tank body away from the ground and solving the problem of the large footprint of the buffer tank body. The motor drives the threaded rod to rotate, which drives the fixed plate to move left and right. The hydraulic cylinder and L-shaped plate drive the buffer tank body to move left and right, thereby increasing the range of motion of the buffer tank body. Attached Figure Description

The bottom of the fixed plate 14 is attached to the top of the support ring 36. The fixed plate 14 and the support ring 36 are connected by the second bolt 15. The bottom is attached to the top of the first connecting plate 26. The first connecting plate 26 and the second connecting plate 32 are connected by the fifth bolt 33, and then the clamping plate 18 is connected. The hydraulic cylinder 11 drives the buffer tank body 2 to move up and down through the fixed plate 14, the support ring 36, the connecting column 35 and the second bolt 15, so that the buffer tank body 2 is away from the ground, solving the problem of the large footprint of the buffer tank body 2. The motor 5 drives the threaded rod 6 to rotate, the threaded rod 6 drives the fixed plate 7 to move left and right, the fixed plate 7 drives the T-shaped block 8 and the crossbar 9 to move left and right, the T-shaped block 8 moves left and right in the T-shaped groove inside the top plate 1, the fixed plate 7 drives the crossbar 10 to move left and right, the crossbar 10 drives the hydraulic cylinder 11 to move left and right, the fixed plate 7 then drives the elastic restraint belt 4 to move left and right, the elastic restraint belt 4 drives the L-shaped plate 16 to move left and right, the hydraulic cylinder 11 and the L-shaped plate 16 drive the buffer tank body 2 to move left and right, thereby increasing the range of movement of the buffer tank body 2.
