Description

Technical Field

[0001] This utility model relates to the field of air buffer tank technology, specifically a compressed air buffer tank with a filtration structure. Background Technology

[0002] Compressed air buffer tanks are common industrial devices primarily used to store and release compressed air to balance and stabilize pressure fluctuations in a system. The filtration structure within the tank is mainly designed to filter out solid impurities and moisture from the compressed air.

Some existing compressed air buffer tanks filter air by incorporating filter plates, moisture-absorbing plates, and drying nets within the manifold at the air inlet. However, this fixed internal filtration structure leads to a decline in filtration efficiency over time, and the integrated manifold makes internal cleaning and maintenance difficult, resulting in inconvenience.

[0042] 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.

[0043] Please see Figure 1-6 In this embodiment of the present invention, a compressed air buffer tank with a filtration structure includes a buffer tank body 10, an air inlet 101 fixedly connected to the outside of the buffer tank body 10, an upper shell 11 fixedly connected to the outside of the buffer tank body 10, a lower shell 12 slidably connected to the outside of the buffer tank body 10, multiple filters 121 and moisture-absorbing plates 122 are provided and fixedly connected to the inner bottom surface of the lower shell 12, multiple air outlet shells 13 are provided and rotatably connected to the inner bottom surface of the lower shell 12, a cleaning brush 131 is fixedly connected to one end of the air outlet shell 13, a drive module 14 is provided on the top of the upper shell 11 and can drive multiple air outlet shells 13, and a limiting module 15 is provided on the outside of the upper shell 11 and can reinforce the connection between the upper shell 11 and the lower shell 12.

[0044] Specifically, multiple air outlet shells 13 are rotatably connected inside the lower shell 12. The positioning plate 123 divides the filter screen 121 and the moisture-absorbing plate 122 into multiple compartments, and the air is divided into multiple streams for synchronous processing. The starting motor 142 drives the multiple air outlet shells 13 to swing back and forth, which can evenly guide the air to the moisture-absorbing plate 122 for moisture absorption. The cleaning brush 131 swings back and forth to clean the impurities on the filter screen 121 in a timely and automatic manner, maintaining the cleaning effect on solid particulate impurities. The lower shell 12 can be separated from the upper shell 11, making the cleaning and maintenance of the filter screen 121 and the moisture-absorbing plate 122 more convenient and easy to use. Example 1

[0045] like Figure 1-5 As shown, in this embodiment, a positioning plate 123 is fixedly connected to the inner bottom surface of the lower shell 12, and multiple partitions 1231 are fixedly connected at equal intervals on both sides of the positioning plate 123. Multiple shafts 132 are rotatably connected to the inner bottom surface of the lower shell 12. The air outlet shell 13 passes through the adjacent shafts 132 and is fixedly connected to them. Air inlet grooves 135 are provided on both sides of the air outlet shell 13. Sponge blocks 134 are fixedly connected to both sides of the air outlet shell 13. A torsion spring 133 is fixedly connected between the bottom end of the air outlet shell 13 and the lower shell 12.

[0046] In this embodiment, the filter screen 121 and the moisture-absorbing plate 122 are divided into multiple compartments by the positioning plate 123 and the partition plate 1231. The air entering the compartments is blown onto the moisture-absorbing plate 122 for further dehumidification by the reciprocating swing of the air outlet shell 13, which enhances the treatment effect and makes full use of the moisture-absorbing plate 122. The rotation of the air outlet shell 13 is limited by the lower shell 12 limiting the shaft 132, so that the air outlet shell 13 can swing back and forth. The air enters the space between the partition plates 1231 through the filter screen 121, undergoes preliminary dehumidification through the sponge block 134, enters the interior of the air outlet shell 13 through the air inlet groove 135, and is then sprayed onto the moisture-absorbing plate 122 through the air outlet shell 13, guiding the air to the moisture-absorbing plate 122 and making full use of multiple parts of the moisture-absorbing plate 122. The cleaning brush 131 at the other end of the air outlet shell 13 swings back and forth to remove impurities stuck on the filter screen 121.

[0047] like Figure 2 As shown, in this embodiment, the drive module 14 includes a protective shell 141, which is fixedly connected to the top of the upper shell 11. The motor 142 is fixedly connected to the top of the upper shell 11. The mounting rod 143 is rotatably connected to the top of the upper shell 11. Multiple bevel gears 144 are provided and fixedly sleeved on the outside of the mounting rod 143. Multiple docking rods 145 are provided and rotatably connected to the inner top surface of the upper shell 11. The bottom end of the docking rod 145 can be movably engaged with the shaft 132. Multiple bevel gears 146 are provided and fixedly sleeved on the top end of the docking rod 145. The bevel gears 146 mesh with the adjacent bevel gears 144.

[0048] In practice, the protective shell 141 protects its internal transmission components. The starting motor 142 drives the mounting rod 143 to rotate, thereby driving multiple bevel gears 144 to rotate. Through the transmission of bevel gears 144 and bevel gears 146, multiple docking rods 145 are driven to rotate, which in turn drives the shafts 132 that are engaged with the docking rods 145 to rotate, thereby driving the air outlet shell 13 to reciprocate and provide power for the movement of the air outlet shell 13. When the lower shell 12 moves down and separates from the upper shell 11, it drives multiple shafts 132 to separate from the docking rods 145. The shafts 132 rotate and reset under the drive of the torsion spring 133, and remain perpendicular to the filter screen 121. This facilitates the automatic alignment of the shafts 132 with the docking rods 145 and docking with them when the lower shell 12 moves up. Example 2

[0049] Based on Embodiment 1, in order to enable faster docking and separation of the upper shell 11 and the lower shell 12, and to make cleaning and maintenance of the internal components of the lower shell 12 more convenient.

[0050] like Figure 2-6As shown, in this embodiment, the outer wall of the buffer tank body 10 is fixedly connected with mounting ring 102 and mounting ring 103. The upper shell 11 is fixedly connected to mounting ring 102, and the lower shell 12 is slidably connected to mounting ring 103. The two sides of the upper shell 11 are respectively fixedly connected to the mating interface 111 and mating interface 112. A sealing ring 113 is fixedly sleeved on the outer wall of the upper shell 11. The limiting module 15 includes multiple card seats 151 and multiple L-shaped rods 152, which are fixedly connected to the outside of the upper shell 11. The L-shaped rods 152 are fixedly connected to the adjacent card seats 151. The insert block 153 is slidably connected to the inside of the card seat 151. The return spring 154 is fixed between the card seat 151 and the insert block 153. The connecting rod 155 is fixed to one end of the insert block 153. The connecting rod 155 passes through the card seat 151 and extends to its outside. Multiple docking seats 156 are provided and fixed to the outside of the lower shell 12. The docking seats 156 are movably engaged with the adjacent card seats 151. The insert block 153 can be movably engaged with the docking seat 156. The C-shaped rod 157 is provided at the bottom of the lower shell 12. Both connecting rods 155 are fixed to the C-shaped rod 157.

[0051] In practice, the upper shell 11 is fixed by mounting ring 102, and the lower shell 12 is slidably limited by mounting ring 103. The lower shell 12 can be separated from the upper shell 11 and moved to a lower position, facilitating cleaning and maintenance of its interior. The upper shell 11 is connected to the air inlet 101 via interface 2 112, and connected to the air supply pipeline via interface 1 111. The sealing ring 113 enhances the sealing at the connection between the upper shell 11 and the lower shell 12. After separation, the lower shell 12 can be moved downwards to a lower position for manual cleaning and maintenance. After processing, push the lower shell 12 upward to contact the upper shell 11. During this process, the docking seat 156 is inserted into the slot 151. After the docking seat 156 moves the arc-shaped end of the insert 153, the return spring 154 resets and drives the insert 153 to be inserted into the docking seat 156, thereby limiting the connection between the slot 151 and the docking seat 156 and fixing the connection between the upper shell 11 and the lower shell 12. By pulling the shaped rod 157, the two inserts 153 can be moved and moved out of the docking seat 156 at the same time, so that the lower shell 12 and the upper shell 11 can be quickly docked and separated.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
