Description

Technical Field

[0001] This utility model relates to the field of gas engineering technology, and in particular to a gas filter element cleaning machine. Background Technology

[0002] Gas filters are crucial components of gas pipeline networks, typically installed at the inlet of pressure reducing valves, relief valves, positioning valves, or other equipment. They filter out impurities such as moisture, tar, and dust to protect valves and equipment, reducing maintenance costs. As the core component of the filter, the filter element accumulates dust and impurities over time, leading to a decline in filtration performance. Therefore, regular cleaning or replacement of the filter element is necessary to ensure filter performance and the safe and stable operation of the gas pipeline network.

[0003] In existing gas filter cartridge cleaning machines, there are spray chambers and drying chambers. The filter cartridges are first cleaned in the spray chamber and then manually transferred to the drying chamber for drying. However, after the filter cartridges are rinsed with high-pressure water, they become heavy due to the adhesion of the cleaning water. In addition, hot water may be used to clean the filter cartridges to ensure the cleaning effect. Under these circumstances, it is not only time-consuming and labor-intensive to manually transfer the filter cartridges from the cleaning chamber to the drying chamber, but the filter cartridges are also at a high temperature after being cleaned with hot water, and direct contact with the human body during the transfer poses a certain danger.

[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0045] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0046] Example 1:

[0047] Embodiment 1 of this utility model provides a gas filter element cleaning machine, such as Figure 1 and Figure 2 As shown, it includes: an adjusting rod 1, multiple hooks 2, a traction steel wire 3, and an I-beam reel 4; the adjusting rod 1 is provided with an adjusting plate 10, one side of the adjusting plate 10 is fixedly connected to the rod body of the adjusting rod 1, and the other side of the adjusting plate 10 is provided with a guide hole 100, through which the traction steel wire 3 passes, the multiple hooks 2 are fixedly connected to one end of the traction steel wire 3, and the other end of the traction steel wire 3 is wound around the I-beam reel 4.

[0048] In actual use, multiple hooks 2 are used to hang the filter element 9 at a preset position to move the filter element 9.

[0049] like Figure 3 As shown, the top of the adjusting rod 1 is provided with a first pulley 11 and a second pulley 12. The first pulley 11 is fixed on the first bracket 110, and the first bracket 110 is fixedly connected to the top of the rod body of the adjusting rod 1. The second pulley 12 is provided on the second bracket 120, and the second bracket 120 is fixedly connected to the top of the adjusting plate 10. The traction steel wire 3 extends from the I-beam wheel 4 to the first pulley 11, and is fixedly connected to the hook 2 via the second pulley 12. The upper end of the hook 2 is provided with a connecting steel wire 20, the top ends of multiple connecting steel wires 20 are fixed to a fixing block 21, the top end of the fixing block 21 is fixedly connected to the traction steel wire 3, and the fixing block 21 is slidably connected to the guide through hole 100, thereby enabling the traction steel wire 3 to drive the fixing block 21 to move up and down, achieving the effect of moving the hook 2 up and down. Specifically, because the traction steel wire 3 is subjected to a larger tension, the strength of the traction steel wire 3 is greater than the strength of the connecting steel wire 20.

[0050] See Figure 2As shown, the cleaning machine further includes a first motor 5 and a second motor 6. The first motor 5 is disposed at the bottom of the adjusting rod 1, and its motor shaft is fixedly connected to the adjusting rod 1 to drive the adjusting rod 1 to rotate. The second motor 6 is disposed on one side of the I-beam wheel 4, and its motor shaft is fixedly connected to the I-beam wheel 4 to drive the I-beam wheel 4 to rotate. The first motor 5 includes a first control switch (not shown in the figure), which controls the start, stop, forward, and reverse rotation of the first motor 5. The second motor 6 includes a second control switch (not shown in the figure), which controls the start, stop, forward, and reverse rotation of the second motor 6. The first motor 5 and the second motor 6 can be induction motors, and their forward and reverse rotation can be achieved by changing the power phase sequence.

[0051] By incorporating an adjusting rod, multiple hooks, traction wires, and I-beams into the gas filter cleaning machine, workers can easily clean the filter by hanging the hooks at a preset position on the filter after cleaning. A second motor is then activated to rotate the I-beams, causing the filter to move upwards. Once the filter reaches the appropriate height, the second motor is turned off, and the first motor is activated to rotate the adjusting rod, transferring the cleaned filter to a preset drying position. The first motor is then turned off, and the second motor is activated again to rotate the I-beams, lowering the filter. After the filter is placed stably, the hooks are removed, and the drying process begins. This system not only reduces lumbar muscle strain caused by bending over to lift the filter but also prevents burns from direct contact with the filter before it has fully cooled down. Furthermore, the adjusting rod, multiple hooks, traction wires, and I-beams eliminate the need for manual handling of the filter, making the cleaning process much more labor-saving.

[0052] In a gas filter cartridge cleaning machine, filter cartridge 9 needs to be dried after cleaning, such as... Figure 4 As shown, the cleaning machine includes a cleaning zone 7 and a drying zone 8, which are arranged adjacent to each other; the cleaning zone 7 is provided with a spray chamber 70, which is used to clean the filter element 9; as shown Figure 5a and Figure 5b As shown, dryers 80 are provided on both sides of the drying area 8, and the dryers 80 are used to dry the cleaned filter element 9.

[0053] To facilitate cleaning of filter element 9, such as Figure 6As shown, the spray chamber 70 is equipped with a turntable 710 and a third motor 711. The third motor 711 is located at the bottom of the turntable 710. The turntable 710 includes multiple first fixing plates 7100 and connecting rods 7101. The first fixing plates 7100 and the connecting rods 7101 are fixedly connected. The multiple first fixing plates 7100 are disposed on the connecting rods 7101. The filter element 9 is placed on the first fixing plates 7100. During the cleaning process of the filter element 9, the third motor 711 will drive the filter element 9 to rotate. To ensure the stability of the filter element 9, a pressure plate 712 is provided on the top of the filter element 9. The pressure plate 712 is fixedly connected to the filter element 9. A first through hole 7120 is provided in the center of the pressure plate 712. The connecting rod 7101 is engaged with the first through hole 7120. The specific snap-fit ​​method between the connecting rod 7101 and the first through hole 7120 can be as follows: the first through hole 7120 has a longitudinal protrusion (not shown in the figure) machined inside, and the top of the connecting rod 7101 has a longitudinal groove (not shown in the figure) corresponding to the protrusion. The protrusion and the groove are snap-fitted to enable the connecting rod 7101 to drive the pressure plate 712 to rotate; or, the connecting rod 7101 is square, and the shape of the first through hole 7120 is also a square through hole that matches it.

[0054] Specifically, the pressure plate 712 includes multiple second fixing plates 7121 and fixing rings 7122. The second fixing plates 7121 are fixedly connected to the filter element 9, and the second fixing plates 7121 are fixedly connected to the fixing rings 7122. The first through hole 7120 is located at the center of the fixing rings 7122. The pressure plate 712 is pre-fixed to the filter element 9 before cleaning. Then, the filter element 9 to be cleaned is placed in the spray chamber 70. When the filter element 9 needs to be transferred to the drying chamber after cleaning, the second fixing plates 7121 are hung on the hooks 2. The shape of the hooks 2 can be as follows: Figure 7 The circle shown ( Figure 7 (left side) or square ( Figure 7 (Right side) Since the second fixed plate 7121 is plate-shaped, it is more stable to use a square hook 2 for lifting.

[0055] In practical application scenarios, such as Figure 8 As shown, the filter element 9 includes an inner filter element 90, a middle filter element 91, and an outer filter element 92. The lengths of the inner filter element 90, the middle filter element 91, and the outer filter element 92 have a preset difference, and the inner filter element 90, the middle filter element 91, and the outer filter element 92 are symmetrically arranged. Both ends of the filter element 9 are stepped. Based on the stepped filter element 9 structure, to ensure the reliability of the first fixing plate 7100 and the second fixing plate 7121 in fixing the filter element 9, refer to... Figure 6As shown, the contact surfaces of the first fixing plate 7100 and the second fixing plate 7121 with the inner filter element 90, the middle filter element 91 and the outer filter element 92 are stepped to match the arrangement of the inner filter element 90, the middle filter element 91 and the outer filter element 92.

[0056] like Figure 9 As shown, the cleaning area 7 is equipped with a cover plate 72, which closes off the area of ​​the cleaning area 7 except for the spray chamber 70. The surface of the cover plate 72 has a second through hole 720, through which the adjusting rod 1 passes and is fixedly connected to the motor shaft of the first motor 5. Wherein, as... Figure 10a and Figure 10b As shown, the radius of the second through hole 720 allows the traction wire 3 passing through the first pulley 11 to pass through, and allows the traction wire 3 to be unobstructed during the rotation of the adjusting rod 1.

[0057] To facilitate the installation of the first motor 5, and to ensure that the installation of the first motor 5 does not occupy the internal space of the cleaning machine, such as Figure 11 As shown, a first mounting plate 73 is provided at the bottom of the cleaning area 7. The first mounting plate 73 is fixedly connected to the housing of the cleaning machine, and the first motor 5 is fixed to the bottom of the first mounting plate 73. To facilitate the installation of the I-beam wheel 4 and the second motor 6 connected to the I-beam wheel 4, a second mounting plate 74 is provided at the bottom of the cleaning area 7. The second mounting plate 74 is fixedly connected to the housing, and the I-beam wheel 4 is fixed to the second mounting plate 74. A third mounting plate 75 is provided at the bottom of the cleaning area 7. The third mounting plate 75 is fixedly connected to the housing, and the second motor 6 is fixed to the third mounting plate 75.
