Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a visible air filter particle replacement device. Background Technology

[0002] When the oil tank or gearbox is vented, the system absorbs air containing water mist. Temperature fluctuations cause the water mist to condense, which accelerates oil oxidation or emulsification, leading to poor lubrication of metal parts and damage. In this case, a filter is needed to treat the air.

[0003] Currently, most filters on the market are one-piece designs, and to facilitate easy replacement of the filter element, one side of the outer shell is usually made of glass. The desiccant used is water-absorbing and color-changing type. However, existing water-absorbing and color-changing desiccants are all granular, and the filter chamber is usually quite deep. Therefore, it is difficult for staff to remove the desiccant from the bottom of the filter during the desiccant replacement process, which affects the efficiency of desiccant replacement.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model discloses a visible air filter particle replacement device.

[0029] Example 1

[0030] Reference Figure 1-5A visible air filter particulate replacement device includes a lower housing 1 and an upper housing 2. An annular visible glass plate 3 is fixedly connected between the lower housing 1 and the upper housing 2. A circular hole is opened on the lower surface of the lower housing 1. A sleeve 4 is fixedly connected inside the circular hole. Two arc-shaped grooves are opened on the inner wall of the sleeve 4. Arc-shaped plates 5 are slidably arranged inside the two arc-shaped grooves. A support block 6 is fixedly connected to one side of each of the two arc-shaped plates 5. An annular plate 7 is slidably sleeved on the outer surface of the sleeve 4. Two support blocks 6 are symmetrically fixedly connected to the inner wall of the annular plate 7. A pull plate 8 is fixedly connected to the upper ends of the two arc-shaped plates 5.

[0031] When using this device, first move the annular plate 7 into the interior of the lower housing 1, then place the filter element particles on top of the annular plate 7, and then fix the device on the oil tank or gearbox. When the filter element particles need to be replaced, the operator only needs to move the pull plate 8 upward, which will then move the annular plate 7 upward and bring out the filter element particles, thus facilitating the replacement of the filter element particles.

[0032] Reference Figure 1-3 A plug 9 is fixedly connected to the lower surface of the pull plate 8. A slot is provided on the upper surface of the sleeve 4. A groove is provided inside the plug 9. A fixing mechanism is provided inside the groove. The plug 9 is fixedly connected to the inside of the slot through the fixing mechanism. The fixing mechanism includes two first trapezoidal blocks 10, a second trapezoidal block 11, a lead screw 12 and a knob 13. Through holes are provided on both sides of the groove. The two first trapezoidal blocks 10 are slidably disposed inside the corresponding through holes. An internal threaded hole is provided on the upper surface of the pull plate 8. The lead screw 12 is threaded inside the internal threaded hole. The second trapezoidal block 11 is rotatably connected to the lower end of the lead screw 12. The knob 13 is fixedly connected to the upper end of the lead screw 12. Two fixing slots are symmetrically provided on both sides of the slot. The two fixing slots are respectively matched with the corresponding first trapezoidal blocks 10.

[0033] When the insert 9 is inserted into the slot, the knob 13 is then rotated to rotate the lead screw 12, which causes the first trapezoidal block 10 to move down and press against the two second trapezoidal blocks 11. The two second trapezoidal blocks 11 are then moved into the corresponding fixing slots, thereby fixing the insert 9.

[0034] Reference Figure 2-3 A reset mechanism is provided at the bottom of the groove. The fixing mechanism matches the reset mechanism. The reset mechanism includes a slide rod 14, two sliders 15 and two springs 16. The slide rod 14 is fixedly connected to the inside of the groove.

The two springs 16 are slidably sleeved on the rod wall of the slide rod 14 and are respectively matched with the corresponding sliders 15.

[0035] When it is necessary to pull the pull plate 8, rotate the knob 13 in the opposite direction to move the first trapezoidal block 10 upward. Then, the rebound force of the two springs 16 can be used to move the two second trapezoidal blocks 11 out of the corresponding fixed slots, thereby allowing the insert block 9 and the pull plate 8 to move.

[0041] The sealing cap 17 prevents filter particles from falling out, while the filter screen 18 allows air to enter easily.

[0042] Example 4

[0043] Based on Example 1, referring to Figure 2 Both sides of the two arc-shaped grooves are provided with strip-shaped holes, and each strip-shaped hole is matched with the corresponding support block 6.

[0044] The two slotted holes facilitate the movement of the corresponding support block 6.
