Description

Technical Field

[0001] This utility model relates to the field of vacuum filter buffer tank technology, specifically a buffer tank that facilitates the replacement of filter devices. Background Technology

[0002] As an important auxiliary device between reciprocating pumps, the buffer tank is used to reduce the unevenness of flow in the pipeline and ensure the normal operation of the pump. The existing buffer tanks are all sealed devices and have basically met the working requirements in use, but there are still some areas that need to be improved.

[0003] A search revealed that Chinese publication CN 211635485 U discloses a vacuum filter buffer tank with easily replaceable filter screens. The tank includes a buffer tank and filter screens. The filter screens are installed inside the buffer tank, and a replacement mechanism is installed inside the filter screens. The replacement mechanism includes hinged rods, a hollow tube, ropes, protrusions, end caps, arc grooves, through holes, threaded openings, and nuts. The outer ends of the four filter screens are fixed to the hinged rods, and the inner ends of the four hinged rods are hinged to the outer wall of the hollow tube. Ropes are connected to the top ends of the hinged rods, and the inner ends of the ropes extend through the hollow tube into its interior. End caps are welded to the top of the hollow tube. Arc grooves are formed on the inner wall of the buffer tank at the outer ends of the hinged rods. This invention enables rapid replacement of the filter screens inside the buffer tank, improving maintenance efficiency and reducing the difficulty of replacing the filter screens.

[0004] However, since the filter devices of most buffer tanks are generally located inside the buffer tank, and the filter screen of the buffer tank needs to be cleaned regularly, most buffer tanks require many disassembly steps when removing the filter screen, which reduces the internal maintenance efficiency of the buffer tank. In view of this, we propose a buffer tank that makes it easy to replace the filter device. Utility Model Content

[0024] 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.

[0025] Example 1

[0026] Please see Figure 1 - Figure 5 This utility model provides a buffer tank for easy replacement of the filter device, including a buffer tank body 1, a base 2 on the lower surface of the buffer tank body 1, and an adjustment mechanism 3 on the upper surface of the base 2. The adjustment mechanism 3 includes a motor 31, which is fixedly connected to the upper surface of the base 2. A threaded rod 32 is rotatably connected to the upper surface of the base 2, passing through the buffer tank body 1 and threadedly connected to it. A cover plate body 33 is rotatably connected to the upper surface of the buffer tank body 1, and the cover plate body 33 is connected to a gear 34 via a transmission shaft. A rack 35 is fixedly connected to the upper surface of the base 2, and the rack 35 meshes with the gear 34. The motor 31... The output shaft is connected to the threaded rod 32 via a transmission component. A ring is fixed on the output shaft of the motor 31, and a ring is also fixed on the outer arc surface of the threaded rod 32. When the two rings are tightly attached, the motor 31 rotates, which drives the threaded rod 32 to rotate, thereby controlling the buffer tank body 1 to move up and down. A limit rod 36 is fixedly connected to the upper surface of the base 2. The limit rod 36 passes through the buffer tank body 1 and is slidably connected to the buffer tank body 1. A connecting sleeve 37 is fixedly connected to the upper surface of the base 2. The connecting sleeve 37 passes through the lower surface of the buffer tank body 1 and is slidably connected to the buffer tank body 1. A leak-proof bucket 38 is fixedly connected to the upper surface of the base 2.

[0027] In this embodiment, through the cooperation of the motor 31, threaded rod 32, gear 34, rack 35 and cover plate body 33, the cover plate body 33 can be automatically opened after the buffer tank moves down to the maximum distance, which facilitates the maintenance of the inside of the buffer tank by the staff.

[0028] Example 2

[0029] Please see Figure 1 - Figure 5Based on Embodiment 1, this utility model provides a technical solution: Preferably, a filter mechanism 4 is provided on the upper surface of the connecting sleeve 37. The filter mechanism 4 includes a fixed plate 41. Filter holes 42 are arranged in a circumferential array on the upper surface of the fixed plate 41. By opening filter holes 42 on the fixed plate 41, the fixed plate 41 has a filtering function. A sliding groove 43 is provided on the upper surface of the fixed plate 41. An L-shaped limiting block 44 is slidably connected to the inner surface of the sliding groove 43. The sliding groove 43 can limit the L-shaped limiting block 44, allowing the L-shaped limiting block 44 to move within the sliding groove 43. The L-shaped limiting block 44 slides stably within the connecting sleeve 37 and is slidably connected to the connecting sleeve 37. A limiting groove 45 is formed on the inner surface of the sliding groove 43. Through the setting of the limiting groove 45, the spring 46 can cooperate with the L-shaped limiting block 44, so that the L-shaped limiting block 44 and the connecting sleeve 37 are firmly locked together. The inner surface of the limiting groove 45 is slidably connected to the L-shaped limiting block 44, and the inner surface of the limiting groove 45 is fixedly connected to one end of the spring 46. The L-shaped limiting block 44 is fixedly connected to the other end of the spring 46. A rotating plate 47 is rotatably connected to the upper surface of the fixing plate 41. 7 is hinged to one end of the bracket 48, and the L-shaped limiting block 44 is hinged to the other end of the bracket 48. A push rod 49 is slidably connected to the inner surface of the connecting sleeve 37. The lower surface of the push rod 49 is fixedly connected to one end of the spring 3 414. The inner surface of the connecting sleeve 37 is fixedly connected to the other end of the spring 3 414. Triangular grooves 410 are linearly arrayed on the inner surface of the connecting sleeve 37. A movable groove 411 is formed on the outer arc surface of the push rod 49. A triangular plate 412 is slidably connected to the inner surface of the movable groove 411. The triangular plate 412 is slidably connected to the inner surface of the triangular groove 410. The triangular groove 410 and the triangular plate 412 cooperate with each other. After the fixed plate 41 loses the limit of the L-shaped limit block 44, the push rod 49 moves upward by the elastic force of the spring 414. At the same time, when the triangular plate 412 moves upward, it is squeezed by the triangular groove 410 and retracts into the movable groove 411. This setting increases the upward friction of the push rod 49, so that the push rod 49 moves upward slowly. It replaces the cylinder and other structures, making the whole equipment more environmentally friendly and energy-saving. The triangular plate 412 is fixedly connected to one end of the spring 413, and the movable groove 411 is fixedly connected to the other end of the spring 413.

[0030] In this embodiment, by setting up the rotating plate 47, the L-shaped limiting block 44, the connecting sleeve 37 and the push rod 49, after rotating the rotating plate 47, the L-shaped limiting block 44 can be driven out of the connecting sleeve 37 by the bracket 48. After the fixed plate 41 loses its limiting position, the push rod 49 pushes the fixed plate 41 upward to the top of the buffer tank body 1. The staff only needs to take the fixed plate 41, making the disassembly of the filter device more convenient.

[0031] Working principle: When it is necessary to disassemble the filter device inside the buffer tank body 1, the motor 31 is started. The output shaft of the motor 31 drives the threaded rod 32 to rotate clockwise, causing the buffer tank body 1 to move downward. At the same time, it drives the gear 34 downward. When the gear 34 moves downward, it is affected by the rack 35 and begins to rotate counterclockwise, which in turn drives the cover plate body 33 to rotate counterclockwise, opening the top of the buffer tank body 1. After opening, the buffer tank body 1 also descends to the bottom. The operator uses tools, such as clamps, to hold the rotating plate 47 and rotate the rotating plate 47 clockwise. The rotating plate 47 drives the L-shaped limiting block 44 to separate to both sides through the bracket 48. The L-shaped limiting block 44 slides... The groove 43 separates to both sides, while compressing the first spring 46. After the L-shaped limiting block 44 disengages from the connecting sleeve 37, the push rod 49 moves upward through the third spring 414, causing the fixed plate 41 to move upward. At the same time, when the triangular plate 412 moves upward, it is squeezed by the triangular groove 410 and retracts into the movable groove 411. The triangular plate 412 compresses the second spring 413. During the upward movement, the triangular plate 412 will repeatedly perform the above actions, increasing the friction of the push rod 49 as it moves upward, causing the push rod 49 to slowly move upward and push the fixed plate 41 upward. After the fixed plate 41 moves above the buffer tank body 1, the staff can directly remove the buffer tank body 1.
