DETAILED DESCRIPTION

[0034] like Figure 1-Figure 10 As shown, a compressor filtering device and filtering method include a cylinder 1, the top of the cylinder 1 is a closed structure, the bottom of the cylinder 1 is an open structure and is sealed by a rotating disk 2, and the rotating disk 2 is rotatably matched with the cylinder 1, referring to Figure 1-Figure 2 As shown, a penetrating air inlet groove 102 is provided on the cylinder wall of the cylinder 1, and a filter is fixedly provided at the air inlet groove 102 for filtering dust in the air. An upper ring body 7 is rotatably installed at the top of the inner part of the cylinder 1, and a lower ring body 10 is provided above the turntable 2, and the lower ring body 10 is fixedly connected to the cylinder 1 through a fixing rod, and multiple groups of dehumidification components are provided between the upper ring body 7 and the lower ring body 10, and the multiple groups of dehumidification components are evenly distributed in a ring array for absorbing moisture in the air;

[0035] Furthermore, the dehumidification assembly includes a top plate 11 and a bottom plate 9, both of which are arc-shaped, and a dehumidification unit 8 is fixedly arranged between the top plate 11 and the bottom plate 9, the top plate 11 is slidably arranged in the upper ring body 7, and the bottom plate 9 is located on the top of the lower ring body 10 and slidably cooperates with the lower ring body 10, combined with Figure 1-Figure 4As shown, a "7"-shaped support rod 5 is fixedly set on the inner side of the bottom plate 9, and the bottom end of the support rod 5 passes through the turntable 2 and can slide up and down relative to the turntable 2. The bottom plate 9 and the lower ring body 10 are matched through a stop assembly, and a motor is arranged under the turntable 2, and the output shaft of the motor is connected to the rotating shaft 3. A push rod 4 is arranged on the outer side of the rotating shaft 3, and the rotating shaft 3 can drive the push rod 4 to rotate around the axis of the turntable 2. The push rod 4 and the support rod 5 are matched through a limit assembly. When the push rod 4 pushes the support rod 5 to rotate in a certain direction through the limit assembly so that the bottom plate 9 is matched with the lower ring body 10 through the stop assembly, the push rod 4 can drive the support rod 5 to rotate in the opposite direction. Through this structure, a dehumidification component can move back and forth at the air inlet groove 102, thereby realizing the sequential use of multiple dehumidification components.

[0036] like Figure 4-Figure 12 As shown, the above-mentioned limit assembly includes a boss 15 arranged on the inner side of the support rod 5 and close to the bottom end, the boss 15 is fixedly connected to the support rod 5, baffles 17 are arranged on both sides above the boss 15, and a convex strip 16 is arranged on the top of the baffle 17. Specifically, the convex strip 16 is fixedly connected to the support rod 5, the convex strip 16 is hinged to the baffle 17, and the position where the convex strip 16 and the baffle 17 are hinged is located at the inner side of the convex strip 16 and the baffle 17. Through this structure, the baffle 17 can only deflect inward relative to the convex strip 16;

[0037] Furthermore, combined with Figure 6 As shown, a magnetic block 1501 is elastically mounted on the top surface of the boss 15, and a magnetic plate 401 matching the magnetic block 1501 is fixedly embedded on the bottom surface of the push rod 4. The magnetic plate 401 has the same magnetic pole on the side opposite to the magnetic block 1501, and the magnetic plate 401 is located at the end of the push rod 4 away from the rotating shaft 3. When the push rod 4 rotates to the side of the baffle 17, it can drive the baffle 17 to deflect inward, so that the end of the push rod 4 away from the rotating shaft 3 can be above the boss 15. At this time, the repulsive force of the magnetic plate 401 on the magnetic block 1501 can drive the magnetic block 1501 to move downward;

[0038] Furthermore, combined with Fig.12 As shown, a first switch 18 and a second switch 20 are respectively installed on both sides of the push rod 4, and the first switch 18 and the second switch 20 are both electrically connected to the motor. The first switch 18 and the second switch 20 can control the forward and reverse rotation of the motor. The first switch 18 and the second switch 20 are both located at one end of the push rod 4 away from the rotating shaft 3, and a pressure plate 19 is provided on the outer side of the first switch 18 and the second switch 20. The pressure plate 19 can be a ring structure, and the pressure plate 19 is elastically matched with the push rod 4.

[0039] Reference Figure 7-Figure 9As shown, the stopper assembly includes a first positioning block 901 and a second positioning block 902 arranged on the outer arc surface of the bottom plate 9. The first positioning block 901 and the second positioning block 902 are elastically matched with the bottom plate 9. Figure 8 As shown, the side of the first positioning block 901 away from the second positioning block 902 is set as a first inclined surface 9011, and the side of the second positioning block 902 away from the first positioning block 901 is set as a second inclined surface 9021. A positioning groove 1001 is provided on the peripheral wall of the inner cavity of the lower ring body 10 away from the support rod 5. Specifically, in combination with Figure 8 As shown, when the base plate 9 rotates clockwise so that the first positioning block 901 moves to the positioning groove 1001, the first positioning block 901 can pop out and insert into the positioning groove 1001, thereby limiting the base plate 9 from continuing to rotate clockwise. Similarly, when the base plate 9 rotates counterclockwise so that the second positioning block 902 is aligned with the positioning groove 1001, the base plate 9 will also stop rotating counterclockwise.

[0040] Combination Figure 7-Figure 9 As shown, a limiting groove 1002 is further provided at the peripheral wall of the inner cavity of the lower ring body 10 away from the support rod 5, and the cross section of the limiting groove 1002 is a triangle, that is, the inner bottom surface of the limiting groove 1002 is inclined, and the depth of the vertical surface of the limiting groove 1002 is greater than the depth of the positioning groove 1001. When the first positioning block 901 or the second positioning block 902 pops out and is inserted into the limiting groove 1002, the first inclined surface 9011 on the first positioning block 901 or the second inclined surface 9021 on the second positioning block 902 will be completely placed in the limiting groove 1002, so that the bottom plate 9 can only rotate in one direction; refer to Figure 7 As shown, the end of the bottom plate 9 adjacent to the air inlet groove 102 (not the bottom plate 9 directly opposite to the air inlet groove 102 ) away from the air inlet groove 102 is located at the limiting groove 1002 .

[0041] Combination Figure 6-Figure 8 As shown, a pull rope 12 is fixedly provided on the end surface of the first positioning block 901 and the second positioning block 902 close to the support rod 5. The pull rope 12 extends upward to the support rod 5 and then converges into a strand and finally passes through the support rod 5 and the boss 15 to be fixedly connected to the bottom surface of the magnetic block 1501. The pull rope 12 is slidably matched with the boss 15, the support rod 5 and the bottom plate 9. Through this structure, when the end of the push rod 4 away from the rotating shaft 3 is located above the boss 15, the magnetic block 1501 can move downward and release the pull rope 12, so that the first positioning block 901 and the second positioning block 902 can pop out.

[0042] Combination Figure 4-Figure 5 , Fig.10As shown, a card slot 1101 is provided on the outer arc surface of the top plate 11, and a card block 13 matching the card slot 1101 is elastically provided on the inner cavity peripheral wall of the upper ring body 7. The side of the card block 13 close to the top plate 11 is an inclined extrusion surface 1301. Through the extrusion surface 1301, when the top plate 11 moves downward, the card block 13 can be compressed so that the card block 13 shrinks to the inside of the upper ring body 7. The number of the card blocks 13 is set to be multiple, refer to Figure 5 As shown, from top to bottom, the elastic force between the plurality of blocks 13 and the upper ring body 7 gradually increases. Through this structure, when the moisture absorbed by the dehumidification component gradually increases, the weight of the dehumidification component gradually increases, so that the dehumidification component can gradually move downward.

[0043] In the initial state, the end of the push rod 4 away from the rotating shaft 3 is located at the support rod 5 below the air inlet groove 102, so that the push rod 4 is above the boss 15. At this time, the repulsive force between the magnetic plate 401 and the magnetic block 1501 can drive the magnetic block 1501 to move downward and release the pull rope 12, so that the first positioning block 901 and the second positioning block 902 on the bottom plate 9 arranged opposite to the air inlet groove 102 are both in a pop-up state. When the push rod 4 drives the support rod 5 to rotate clockwise and the first positioning block 901 is aligned with the positioning groove 1001, the first positioning block 901 can pop out and be inserted into the positioning groove 1001. The cooperation between the positioning groove 1001 and the first positioning block 901 can prevent the bottom plate 9 from continuing to rotate clockwise. In this case, the pressure plate 19 located on the outside of the first switch 18 will contact and squeeze the baffle 17 adjacent to it, so that the pressure plate 19 at the first switch 18 can shrink into the push rod 4, and the first switch 18 follows the trend with one side thereof. 1001, so that the first positioning block 901 can move out of the positioning groove 1001. When the bottom plate 9 rotates counterclockwise along the lower ring body 10 and the second positioning block 902 is aligned with the positioning groove 1001, the bottom plate 9 can be prevented from rotating counterclockwise by the cooperation between the positioning groove 1001 and the second positioning block 902, so that the pressure between the pressure plate 19 and the baffle 17 at the second switch 20 increases, so that the second switch 20 can contact the baffle 17, and then control the motor to change the direction of operation again. Through this structure, the dehumidification component opposite to the front of the air inlet groove 102 can be driven to reciprocate at the air inlet groove 102, so that moisture in the air can be absorbed;

[0044] When the dehumidification component on the front of the air inlet groove 102 absorbs a certain amount of moisture and its weight increases, the pressure of the top plate 11 on the topmost block 13 increases, so that the topmost block 13 can move out of the slot 1101. As the top plate 11 slides downward, the second block 13 from the top to the bottom will align with the slot 1101 on the top plate 11. Since the elastic force between the multiple blocks 13 and the upper ring body 7 gradually increases from top to bottom, the top plate 11 can be limited again by the second block 13 from the top to the bottom. After moving a certain distance, the push rod 4 will be offset from the baffle 17 under the dehumidification component in the horizontal plane. When the motor drives the push rod 4 to rotate again, the push rod 4 can rotate to the side of the support rod 5 on the next bottom plate 9. During this process, the push rod 4 will push the baffle 17 on the support rod 5 to deflect inward, so that the end of the push rod 4 away from the rotating shaft 3 can be above the boss 15. Similarly, the cooperation between the magnetic plate 401 and the magnetic block 1501 can cause the first positioning block 901 and the second positioning block 902 on the bottom plate 9 to be in a pop-up state. Figure 7 As shown, here, the push rod 4 rotates clockwise to the next base plate 9 as an example. When the second positioning block 902 on the base plate 9 is in a pop-up state, the second inclined surface 9021 on the second positioning block 902 can completely enter the limit groove 1002, thereby preventing the base plate 9 from rotating clockwise. Therefore, when the push rod 4 continues to rotate clockwise with the rotating shaft 3, the pressure plate 19 on the outside of the first switch 18 will contact and squeeze the baffle 17, so that the first switch 18 contacts the baffle 17 and drives the push rod 4 to rotate counterclockwise. With the counterclockwise rotation of the push rod 4, the base plate 9 originally on the side of the air inlet groove 102 and adjacent to the air inlet groove 102 will be driven to a position opposite to the front of the air inlet groove 102. According to the above description, in the subsequent operation process, the base plate 9 on the front of the air inlet groove 102 can move back and forth with the push rod 4.

[0045] In summary, through this structure, the dehumidification component on the front of the air inlet slot 102 can be prompted to reciprocate at the air inlet slot 102, and when the dehumidification component on the front of the air inlet slot 102 absorbs a certain amount of moisture and fails to meet the corresponding dehumidification requirements, the dehumidification component on one side of the air inlet slot 102 can be driven to the front of the air inlet slot 102 through the push rod 4 and reciprocate relative to the air inlet slot 102. Therefore, multiple dehumidification components in this scheme can be used in sequence.

[0046] Reference Figure 2As shown, an annular plate is sleeved on the outer side of the rotating shaft 3, and the annular plate can move in the vertical direction relative to the rotating shaft 3, and the push rod 4 is fixedly arranged on the outer peripheral wall of the annular plate, and a plurality of insertion holes 301 are opened on the outer peripheral wall of the rotating shaft 3, and the plurality of the insertion holes 301 are evenly distributed in the vertical direction. A plug rod cooperating with the insertion holes 301 is slidably arranged on the annular plate. Through this structure, the position of the push rod 4 can be adjusted in the vertical direction. In specific applications, when the dryness of the compressed gas is required to be high, the push rod 4 can be adjusted to move upward so that the push rod 4 and the unused dehumidification components are aligned. The baffle 17 below can be aligned on a horizontal plane. According to the above description, the unused dehumidification component can be driven to the front of the air inlet groove 102 through the push rod 4 and reciprocate relative to the air inlet groove 102, thereby improving the drying effect of the gas. Of course, when the dryness requirement of the gas is lower, the push rod 4 can be adjusted to move downward so that the push rod 4 and the baffle 17 below the used dehumidification component can be aligned on a horizontal plane, so that the used dehumidification component can be driven to the front of the air inlet groove 102 and reciprocate relative to the air inlet groove 102, which is conducive to full utilization of the dehumidification component.

[0047] To sum up, in this scheme, the dehumidification components are not driven to rotate in one direction all the time, but multiple groups of dehumidification components are arranged. The multiple groups of dehumidification components are arranged in a cylindrical shape, and only one dehumidification component is located in front of the air inlet groove 102 at a time and reciprocates relative to the air inlet groove 102. According to different requirements for gas dryness, the corresponding dehumidification components can be driven to move to the air inlet groove 102, thereby eliminating the need to frequently replace the dehumidification components.
