[0024] When corrosion occurs inside the filter, not only will the filtering effect be reduced, but also sewage leakage may occur due to severe corrosion perforation, which not only wastes resources but also threatens the environment and human health. Therefore, the anti-corrosion inside the filter is very important. However, the applicant has found through research that the preparation of the anti-corrosion layer on the inner wall of the filter is usually done by brushing or manual rolling, which has the problems of uneven brushing and uneven thickness, making the anti-corrosion layer easy to fall off, thereby affecting the anti-corrosion effect. In addition, the brushing process has a strong odor and labor protection is difficult, which is not conducive to the health of the operator.

[0025] Therefore, the utility model proposes a filter inner wall anti-corrosion layer preparation system, see Figure 1 , Figure 1 FIG. 1 is a schematic diagram of a system for preparing an anti-corrosion layer inside a filter according to an exemplary embodiment of the present invention. Figure 1 As shown, the exemplary system for preparing the anti-corrosion layer inside the filter includes at least:

[0026] A liftable bracket is provided with a pair of rotatable exoskeletons facing each other; the exoskeletons laterally fix the ends of the filter 5, the filter 5 is cylindrical and contains an anti-corrosion fluid; a driving device is connected to one side of the exoskeleton through a bearing, and is used to drive the exoskeleton to drive the filter 5 to rotate, so that the anti-corrosion fluid is evenly attached to the inner wall of the filter under the action of centrifugal force to form an anti-corrosion layer.

[0027] In this embodiment, the preparation of the anti-corrosion layer on the inner wall of the filter 5 is convenient. At the same time, under the rotating and lifting operation of the liftable bracket and the rotatable exoskeleton, the filter 5 can be fully covered with the anti-corrosion fluid on the inner wall and the port of the filter 5 with uniform thickness, thereby avoiding the problem of the anti-corrosion layer falling off due to uneven coating and uneven thickness, enhancing the reliability of the anti-corrosion layer and the anti-corrosion effect of the filter. In addition, the automated preparation of the anti-corrosion layer on the inner wall of the filter 5 saves manpower and avoids the problem of harm to the human body caused by the anti-corrosion material.

[0028] It should also be noted that an anti-corrosion fluid needs to be placed in the filter 5 in advance. In addition, in order to make the anti-corrosion fluid fully cover the inner wall and port of the filter 5 more effectively, preferably, the shape of the applicable filter 5 is cylindrical.

[0029] Specifically, the liftable bracket includes a first bracket 1 and a second bracket 2, and a spherical connector 8 is provided at the top of the first bracket 1 and the second bracket 2. The bearing includes a first bearing 6 and a second bearing 7. The first bracket 1 and the second bracket 2 are spherically connected to the first bearing 6 and the second bearing 7 respectively through the spherical connector 8 to support the first bearing 6 and the second bearing 7, wherein the height of the first bracket 1 and the second bracket 2 is adjustable.

[0030] In this embodiment, the height of the first bracket 1 and the second bracket 2 is adjustable, and the height of the first bracket 1 and the second bracket 2 can be adjusted to be the same or different. When the height of the first bracket 1 and the second bracket 2 are the same, the filter 5 is horizontal. At this time, under the action of rotation, the anti-corrosion fluid can be evenly attached to the side wall of the filter 5. When the height of the first bracket 1 and the second bracket 2 are different, the two ends of the filter 5 can be in a state of high on the left and low on the right or low on the left and high on the right. At this time, under the action of rotation, the two ends of the filter 5, that is, the end head and the end cap, can meet the uniform adhesion of the anti-corrosion fluid.

[0031] In addition, the first bracket 1 and the second bracket 2 are spherically connected to the first bearing 6 and the second bearing 7 respectively through the spherical connection 8. Through the spherical connection, the first bearing 6 and the second bearing 7 can rotate at any angle and direction based on the first bracket 1 and the second bracket 2, and the spherical connection 8 can slide within a certain length range of the first bearing 7 or the second bearing 7. The length range can be set based on the maximum height difference between the first bracket 1 and the second bracket 2. In this way, when the heights of the first bracket 1 and the second bracket 2 are different, the rotation of the first bearing 6 and the second bearing 7 is not affected.

[0032] In one embodiment, the exoskeleton includes a first exoskeleton 3 and a second exoskeleton 4. The first exoskeleton 3 and the second exoskeleton 4 are respectively connected to the first bearing 6 and the second bearing 7. The first exoskeleton 3 is used to fix one end of the filter 5, and the second exoskeleton 4 is used to fix the other end of the filter 5.

[0033] In this embodiment, the first exoskeleton 3 and the second exoskeleton 4 can be connected to the first bearing 6 and the second bearing 7 respectively by fasteners, so that the first exoskeleton 3 and the second exoskeleton 4 are detachable, and exoskeletons of different sizes can be installed corresponding to filters 5 of different sizes.

[0034] In one embodiment, the first exoskeleton 3 and the second exoskeleton 4 are C-shaped, and the openings are arranged opposite to each other, and the size of the openings is adjusted according to the size of the filter 5 .

[0035] In this embodiment, the opening sizes of the first exoskeleton 3 and the second exoskeleton 4 can be adjusted according to the size of the filter 5, so that the exoskeleton can be suitable for filters of different sizes.

[0036] In one embodiment, the driving device includes a servo motor 9 and a reducer 10 connected to the servo motor 9 through a coupling 11. The rotation speed of the servo motor 9 is adjusted according to the anti-corrosion fluid parameters and the filter parameters, and the rotation speed is negatively correlated with the rotation time. The anti-corrosion fluid parameters at least include the composition, dosage, flow properties and adhesion ability of the anti-corrosion fluid, and the filter parameters at least include the filter size.

[0037] In this embodiment, the servo motor 9 and the reducer 11 are used as a power transmission combination, so that the rotation speed and torque can be accurately controlled and adjusted, and the high-speed rotation output by the servo motor 9 can be reduced by the reducer 11 to increase the output torque.

[0038] It should be noted that the rotation speed of the servo motor 9 is set based on the anti-corrosion fluid parameters and the filter parameters, taking into account that different anti-corrosion fluids have different compositions, dosages, flow properties and adhesion capabilities, that is, the flow and adhesion capabilities inside the filter 5 are different, and filters 5 of different sizes have different inner wall areas and different requirements for rotation speeds. Therefore, the rotation speed is adjusted and controlled based on the anti-corrosion fluid parameters and the filter parameters. It should also be noted that the anti-corrosion fluid parameters include but are not limited to the composition, dosage, flow properties and adhesion capabilities of the anti-corrosion fluid, and the filter parameters include but are not limited to the filter size.

[0039] In one embodiment, the system further includes a heating device 12 wrapped around the outer surface of the filter 5 for heating the filter 5 .

[0040] In this embodiment, the heating device 12 generates heat, and through heat transfer, the anti-corrosion fluid quickly forms an anti-corrosion layer on the inner wall of the filter 5, and the formation of the anti-corrosion layer is accelerated by heating. It should be noted that the heating device 12 is a wrapped type, wrapped around the outer surface of the filter 5, and rotates with the filter 5.

It should be understood that when heating by an external power supply, the filter 5 containing the anti-corrosion fluid should be heated before being fixed on the exoskeleton, and then the power supply should be disconnected so as not to affect the rotation of the filter 5.

[0043] In one embodiment, the system further includes a temperature control device 13 connected to the heating device 12 for controlling the heating temperature of the heating device 12 .

[0044] It should be noted that the temperature control device 13 is independently provided with the heating device 12, and is in communication connection with the heating device 12, and has no influence on the heating temperature. In addition, the heating temperature can be set based on the rotation time, rotation speed and anti-corrosion fluid parameters of the driving device, wherein the anti-corrosion fluid parameters include but are not limited to the composition, dosage, fluidity and adhesion of the anti-corrosion fluid.

[0045] In a possible embodiment, the temperature control device 13 may also be disposed inside the heating device 12 and integrated with the heating device 12 .

[0046] In one embodiment, the outer surface of the heating device 12 is provided with a heat-insulating layer.

[0047] In this embodiment, the heat insulation layer can effectively reduce the heat dissipation of the heating device 12 and is more conducive to the formation of an anti-corrosion layer on the inner wall of the filter 5.

[0048] In one embodiment, the liftable bracket is any one of a hydraulic lift bracket, an electric lift bracket, and a pneumatic lift bracket.

[0049] It should be noted that this embodiment does not limit the specific type or structure of the liftable bracket, and the left and right brackets of the liftable bracket, that is, the first bracket 1 and the second bracket 2 can be adjusted in height respectively.

[0050] The above-mentioned system for preparing the anti-corrosion layer on the inner wall of the filter includes a liftable bracket, and a pair of rotatable exoskeletons are arranged opposite to each other on the liftable bracket, the exoskeletons laterally fix the ends of the filter and have an anti-corrosion fluid built in, and then the driving device is connected to one side of the exoskeleton through a bearing, and the exoskeleton is driven by the driving device to drive the filter to rotate, so that the anti-corrosion fluid is evenly attached to the inner wall of the filter under the action of centrifugal force to form an anti-corrosion layer. This system makes the preparation of the anti-corrosion layer on the inner wall of the filter convenient, and at the same time, under the rotation and lifting operation of the liftable bracket and the rotatable exoskeleton, the filter can make the anti-corrosion fluid fully cover the inner wall and port of the filter with uniform thickness, avoiding the problem of anti-corrosion layer falling off due to uneven coating and uneven thickness, enhancing the reliability of the anti-corrosion layer and the anti-corrosion effect of the filter.
