Its sources mainly include mechanical impurities that remain in the hydraulic system after cleaning, such as water rust, casting sand, welding slag, iron filings, coatings, paint skin and cotton yarn scraps, etc., impurities that enter the hydraulic system from the outside, such as dust entering through the refueling port and dust ring, etc.; impurities generated during the working process, such as fragments formed by the hydraulic action of the seal, metal powder generated by relative wear of the movement, colloid, asphalt, carbon slag, etc. generated by oxidation and deterioration of the oil.

[0003] like Figure 5 As shown, the hydraulic filter is generally composed of a filter element (or filter screen), a housing (or frame) and an end cover, wherein the end cover is provided with a liquid inlet and a liquid outlet. During the processing of the hydraulic filter, its housing and end cover need to be painted to improve its corrosion resistance.

[0036] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0037] like Figure 1-4 As shown, the present invention provides a hydraulic filter painting equipment, the equipment comprising: a storage barrel 1, a lifting seat 2, a rotating disk 3 and a clamp 5;

[0038] The storage barrel 1 storing the paint is provided with a lifting seat 2 which can be extended from its opening in a horizontal and liftable manner. A rotating disk 3 is provided horizontally and coaxially rotatably on the upper end of the lifting seat 2. A clamp 5 for clamping a hydraulic filter is provided on the rotating disk 3. The clamp 5 includes: a screw 501, a limiting plate 502 and a positioning cone 503; wherein,

[0039] Two brackets 4 are fixedly arranged at intervals and vertically symmetrically on the upper end of the rotating disk 3, and two screw rods 501 connected to the respective threads are horizontally and symmetrically penetrated through the upper ends of the two brackets 4, and limiting plates 502 are coaxially and rotatably arranged on adjacent ends of the two screw rods 501, and a positioning cone 503 adapted to the liquid inlet or liquid outlet of the hydraulic filter is coaxially and horizontally fixedly arranged on each of the limiting plates 502 facing away from the screw rods 501.

[0040] In the above scheme, a sufficient amount of paint is placed in the storage barrel 1 for standby use.

[0041] When in use, the hydraulic filter is vertically fixed on the clamp 5, and the lifting seat 2 is driven to drive the rotating disk 3 and the hydraulic filter fixed on the rotating disk 3 by the clamp 5 in the vertical direction to extend from the opening of the storage barrel into the interior thereof and be completely immersed in the paint therein, and then stand still for 5-10 seconds, and then the lifting seat 2 is driven to rise in the reverse vertical direction until the lifting seat 2 is exposed from the opening of the storage barrel 1, and the rotating disk 3 is rotated to drive the hydraulic filter fixed thereon by the clamp 5, and the hydraulic filter with paint on its surface can be shaken off during the rotation of the rotating disk 3, so that the hydraulic filter can be further evenly coated, thereby improving the uniformity of the painting, and the entire surface of the hydraulic filter can be fully painted, without the need to distribute the paint on the hydraulic filter, thereby improving the working efficiency of the painting equipment.

[0042] In addition, the use principle of the clamp 5 is as follows: Figure 1-3 As shown, the hydraulic filter is inverted, and the liquid inlet (liquid outlet) on the hydraulic filter is placed on the positioning cone 503 on one of the screw rods 501, and the liquid inlet is pressed against the corresponding limiting plate 502, and the other screw rod 501 is rotated to drive the positioning cone 503 on its end to move toward the liquid outlet (liquid inlet) of the hydraulic filter until the positioning cone 503 extends into the liquid inlet and the limiting plate 502 presses against the liquid outlet, so that the hydraulic filter is vertically suspended between the two brackets 4.

[0043] In addition, the clamp 5 fixes the hydraulic filter through the two positioning cones 503, and the two limiting plates 502 abut against the liquid inlet and outlet of the hydraulic filter. On the one hand, the clamp 5 will not block the hydraulic filter during the clamping process of the hydraulic filter, avoiding the occurrence of dead corners in the process of painting and affecting the painting effect; on the other hand, the outer walls of the two positioning cones 503 can contact the inner walls of the liquid inlet and outlet of the hydraulic filter, and the two limiting plates 502 abut against the ports of the liquid inlet and outlet, thereby sealing the hydraulic filter to prevent it from entering the interior of the hydraulic filter during the painting process, especially affecting its normal use.

[0044] In a preferred embodiment of the present invention, each positioning cone 503 is sleeved with a rubber sleeve.

[0045] In the above solution, the rubber sleeve further plays a sealing role to prevent liquid from entering the interior of the hydraulic filter through the liquid inlet and outlet during the painting process, thereby preventing the normal use of the hydraulic filter from being affected.

[0046] In a preferred embodiment of the present invention, a recovery bucket 8 is coaxially fixedly sleeved on the upper open end of the storage bucket 1 .

[0047] In the above scheme, when the lifting seat 2 drives the rotating disk 3 and the hydraulic filter clamped and fixed thereon by the clamp 5 to extend from the open mouth of the storage barrel 1, in the process of driving the rotating disk 3 to drive the hydraulic filter to rotate, the excess paint on the surface of the hydraulic filter is thrown onto the inner wall of the recovery barrel 8 and flows into the inner wall of the recovery barrel 8 along its inner wall to achieve the purpose of recycling, while avoiding the paint splashing everywhere and polluting the surrounding environment and causing waste of resources in the process of the rotating disk 3 driving the hydraulic filter to rotate.

[0048] In a preferred embodiment of the present invention, the device further comprises a driving mechanism 6 for driving the rotating disk 3 extending from the opening of the storage barrel 1 to rotate in a horizontal direction, wherein the driving mechanism 6 comprises: a moving plate 601, a driving gear 602 and a driving motor 603; wherein,

[0049] A circle of rack groups are vertically fixed on the side wall of the rotating disk 3 at equal intervals along its circumferential direction, and a movable plate 601 that moves toward the clamp 5 is horizontally and movably arranged inside the recovery bin 8 located above the rotating disk 3, and a driving gear 602 that can be meshed and connected with the rotating disk 3 is horizontally and rotatably arranged below the movable plate 601, and a driving motor 603 is vertically fixed on the upper end of the movable plate 601, and its output shaft is coaxially fixedly connected to the driving gear 602 through a coupling.

[0050] In the above scheme, when in use, when the lifting seat 2 drives the rotating disk 3 and the hydraulic filter clamped and fixed thereon by the clamp 5 to extend from the open mouth of the storage barrel 1 until the rotating disk 3 is flush with the driving gear 602, the movable plate 601 is driven to move toward the clamp 5 until the driving gear 602 is meshed and connected with the rotating disk 3, the driving motor 603 is started to drive the driving gear 602 to drive the rotating disk 3 meshed with it to drive the hydraulic filter fixed thereon to rotate together, thereby shaking off excess paint on the surface of the hydraulic filter to improve the uniformity of the coating on the hydraulic filter.

[0051] In addition, a stop block (not shown) is fixedly disposed horizontally on the inner wall of the recovery barrel 8 to limit the rising lifting seat 2 to prevent the lifting seat 2 from extending from the opening of the storage barrel 1 until the lifting seat 2 abuts against the stop block. At this time, the rotating disk 3 on the lifting seat 2 is flush with the driving gear 602.

[0052] In a preferred embodiment of the present invention, the driving mechanism 6 further includes a cylinder 604 for driving the moving plate 601 to move in a horizontal direction; wherein,

[0053] A special-shaped rod 7 with an n-shaped structure is vertically fixed on the end of the movable plate 601 away from the clamp 5, and the other end of the special-shaped rod 7 extends out from the opening of the recovery barrel 8 and is parallel to its side wall, and a cylinder 604 is horizontally fixed on the outer wall of the recovery barrel 8, and the free end of its piston rod is fixed on the special-shaped rod 7.

[0054] In the above solution, when in use, the movable plate 601 is driven to move in the horizontal direction through the special-shaped rod 7 during the process of driving the piston rod of the cylinder 604 to extend or retract from the cylinder raising part.

[0055] The cylinder 604 is a well-known technical means, so its specific structure and use principle will not be repeated here.

[0056] In a preferred embodiment of the present invention, the device further comprises a lifting mechanism 9 for driving the lifting seat 2 to lift in a vertical direction, wherein the lifting mechanism 9 comprises: a traction rope 901, a winding wheel 902 and a winding motor 903; wherein,

[0057] The outer wall of the recovery barrel 8 is horizontally and fixedly provided with a winding motor 903, and a winding wheel 902 is coaxially fixedly provided on its output shaft. One end of the traction rope 901 is fixed on the lifting seat 2, and the other end thereof extends from the open mouth of the recovery barrel 8 and is fixed on the winding wheel 902.

[0058] In the above solution, when in use, the winding motor 903 is started to drive the winding wheel 902 to rotate so as to reel in or unreel the traction rope 901 .

[0059] When the winding wheel 902 reels the traction rope 901 during rotation, the lifting seat 2 can be driven to rise in the vertical direction; and when the winding wheel 902 unwinds the traction rope 901 during rotation, the lifting seat 2 can descend in the vertical direction under the action of its own gravity.

[0060] Therefore, the lifting base 2 can be driven to move up and down in the vertical direction through the lifting mechanism 9 .

[0061] In a preferred embodiment of the present invention, the inner wall of the storage barrel 1 is provided with a plurality of guide rails 12 vertically fixed at equal intervals along its circumferential direction, and the side wall of the lifting seat 2 is recessed inward at equal intervals along its circumferential direction to form guide grooves compatible with all the guide rails 12, and the lifting seat 2 can be slidably assembled on all the guide rails 12 through all the guide grooves.

[0062] In the above solution, by using the plurality of guide rails 12 in coordination with the plurality of guide slots on the lifting seat 2, it is possible to ensure that the lifting seat 2 can be lifted and lowered in a straight line in a stable and reliable manner in the vertical direction.

[0063] In a preferred embodiment of the present invention, a recovery pipe 10 is fixedly provided on the side wall at the bottom of the recovery barrel 8 , the other end of the recovery pipe 10 is fixedly provided on the storage barrel 1 , and a one-way valve 11 is fixedly provided on the recovery pipe 10 .

[0064] In the above scheme, the paint collected in the recovery barrel 8 can flow from high to low through the recovery pipe 10 into the liquid storage barrel 1 for recycling and reuse, thereby avoiding waste of resources.

[0065] The medium flow direction of the one-way valve 11 is such that the medium can only flow into the storage barrel 1 through the recovery pipe 10 , so as to prevent the medium in the storage barrel 1 from flowing back into the recovery barrel 8 through the recovery pipe 10 .

[0066] In a preferred embodiment of the present invention, an operation opening is provided on the side wall of the recovery barrel 8, and a sealing door 14 is provided on the operation opening to seal the operation opening.

[0067] In the above scheme, it is convenient to fix the hydraulic filter on the lifting seat 2 in the recovery barrel 8 through the operating port. During the painting process, the sealing door 14 is covered on the operating port to prevent the paint on the surface of the hydraulic filter clamped and fixed thereon from being thrown out from the operating port and polluting the surrounding environment during the rotation of the rotating disk 3.

[0068] In addition, the recovery barrel 8 and the storage barrel 1 can be made of transparent material to facilitate observation of the painting condition.

[0069] In summary, the hydraulic filter painting equipment provided by the present invention overcomes the problem in the prior art that the end cover and the shell are sprayed separately, and during the spraying process, the end cover or the shell is clamped by a clamp, which results in that during spraying, the part of the end cover or the shell blocked by the clamp cannot be sprayed, resulting in dead angles for painting and reducing the problem of spraying effect.

[0070] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0071] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0072] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
