Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil return filter elements, in particular to a hydraulic oil return filter element with slow-release filtering capacity. Background Art

[0002] Hydraulic return oil filters are installed in the hydraulic system's oil circuit to remove mechanical impurities such as metal powder, keeping the circuit clean and extending the life of the hydraulic system. Hydraulic return oil filters are available in a variety of filter materials, including metal mesh and paper. Metal mesh filters are washable and reusable. Compared to filter elements made with paper, filter elements made with metal mesh have superior physical properties, can withstand pressure fluctuations in the hydraulic system, and are washable.

[0003] The prior art, with publication number CN112797052B, provides a hydraulic return oil filter element with slow-release filtration capacity, comprising a coaxially arranged protective screen, a metal mesh filter material, and an upper cover assembly and a lower cover assembly arranged at both ends; the metal mesh filter material has a plurality of coaxial cylindrical filter material layers, with a certain distance between adjacent cylindrical filter material layers to form an annular cavity; an oil passage is provided in the cylindrical filter material layers between adjacent annular cavities, and a valve valve is provided in the oil passage to control opening and closing; the valve valve is composed of an elastic baffle, and when the pressure difference between adjacent annular cavities is greater than a set value, the valve valve opens. By gradually releasing the filtration capacity of the thicker metal mesh filter material, the filtration capacity is used in portions, and the filtration capacity of each portion is fully utilized, thereby solving the problem of increased resistance during operation caused by increased filtration capacity.

[0004] In the above patent, a multi-layer filtering structure is mainly provided in the hydraulic filter element, and the valve valve is opened in conjunction with the pressure difference, so as to use the filtering capacity of the return oil filter element in portions and make full use of the filtering capacity of each portion. However, this method of slow-release of filtering capacity requires more filter mesh materials to be provided in the hydraulic filter element, which will cause the hydraulic oil to encounter more resistance when flowing through the return oil filter element, thereby greatly reducing the efficiency of hydraulic oil circulation. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a hydraulic return oil filter element with slow-release filtering capacity, which solves the technical problem that the hydraulic oil encounters more resistance when flowing through the return oil filter element.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a hydraulic return oil filter element with slow-release filtration capacity, comprising an adjustment component, an intelligent component, and a filter element body. A mounting bottom cover is fixedly mounted on one end of the filter element body away from the intelligent component. Both the adjustment component and the intelligent component are fixedly mounted on the side of the filter element body away from the mounting bottom cover. The adjustment component is used to adjust the amount of liquid that can flow through the filter holes on the outer surface of the filter element body. The intelligent component includes a single-chip microcomputer and a placement plate. The single-chip microcomputer is placed on the placement plate and is used to control the operation of the adjustment component. The single-chip microcomputer controls the operation of the adjustment component, greatly enhancing the intelligent operation of the hydraulic return oil filter element with slow-release filtration capacity.

[0007] Furthermore, the adjustment assembly includes a motor and a rotary disk. A drive shaft is fixedly mounted on the output end of the motor. The drive shaft is fixed to the rotary disk on a side away from the motor. A plurality of driving teeth are fixedly mounted on the outer ring of the rotary disk. The motor is electrically connected to the single-chip microcomputer. This electrical connection between the motor and the single-chip microcomputer directly controls the start and stop of the motor, thereby improving the filtration capacity and the integrity of the internal structure and operation of the slow-release hydraulic return oil filter element.

[0008] Furthermore, the adjustment assembly includes a disc with a rotating shaft fixed through its center. A plurality of passive teeth are fixedly mounted on the outer ring of the disc, and the passive teeth mesh with the active teeth. This meshing of the passive teeth with the active teeth allows the active teeth to rotate directly with them, thereby improving the filtration capacity and the synchronization of the internal structure of the slow-release hydraulic return oil filter element.

[0009] Furthermore, a plurality of adjusting bodies are fixedly mounted on the rotating shaft. The number of adjusting bodies corresponds to the number of filter holes in a row of the return oil filter element. The adjusting bodies are used to adjust the opening size of the filter holes. The adjusting bodies are used to adjust the opening size of the filter holes, allowing the slow-release hydraulic return oil filter element to quickly and effectively release its filtering capacity, thereby improving the practicality of its operation.

[0010] Furthermore, a protective cover is fixedly mounted on one side of the placement tray near the microcontroller, and is used to seal and protect the microcontroller. This seals and protects the microcontroller, ensuring that the internal structure of the slow-release hydraulic return oil filter element remains sealed during operation, thereby improving the safety of its operation.

[0011] Furthermore, several support frames are fixedly mounted on the outside of the placement tray. Several of the support frames have notches on the side close to the placement tray, which are used to seal the protective cover. The intelligent component also includes a flow sensor, which is fixedly mounted on the side of the support frame away from the single-chip microcomputer. The support frame has a hollow hole inside. The flow sensor is electrically connected to the single-chip microcomputer through the hollow hole inside the support frame. When the flow sensor senses that the flow rate exceeds a threshold, it will directly provide an electrical signal to the single-chip microcomputer, greatly improving the filtering capacity and the intelligent operation of the internal structure of the slow-release hydraulic return oil filter element.

[0012] Furthermore, the regulating body is in the shape of a sphere with a through hole. The regulating body is in the shape of a sphere with a through hole, which allows the regulating body to more efficiently adjust the filter holes outside the filter element body, thereby improving the filtering capacity and the convenience of using the slow-release hydraulic return oil filter element. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The utility model uses a flow sensor to sense the hydraulic oil flow rate flowing through the hydraulic return oil filter element to determine the blockage degree of the filter element, and cooperates with a single-chip microcomputer electrically connected to the flow sensor to control the rotation of the regulating body, so as to adjust the size of the filtering holes on the surface of the hydraulic return oil filter element and achieve the effect of slowly releasing the filtering capacity of the hydraulic return oil filter element, thereby greatly improving the practicality of using the filtering capacity slow-release hydraulic return oil filter element.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example

[0024] The following is combined with Figure 1 -Attached Figure 6 , this application is further described in detail. A hydraulic return oil filter element with slow-release filtering capacity includes an adjusting component 1, an intelligent component 3, and a filter element body 4. The end of the filter element body 4 away from the intelligent component 3 is fixedly installed with a mounting bottom cover 5. The adjusting component 1 and the intelligent component 3 are fixedly installed on the side of the filter element body 4 away from the mounting bottom cover 5. The adjusting component 1 is used to adjust the amount of liquid that can flow through the filter holes on the outer surface of the filter element body 4. The intelligent component 3 includes a single-chip microcomputer 31 and a placement plate 32. The single-chip microcomputer 31 is placed on the placement plate 32. The single-chip microcomputer 31 is used to control the operation of the adjusting component 1. The adjusting component 1 includes a motor 13 and a turntable 14. The output end of the motor 13 is fixedly installed with a drive shaft 18. The drive shaft 18 is fixed to the turntable 14 on the side away from the motor 13. A plurality of active teeth 15 are fixedly installed on the outer ring of the turntable 14. The motor 13 is electrically connected to the single-chip microcomputer 31. The adjusting component 1 also includes a disc 16. The middle of the disc 16 is fixed with a rotating shaft 11. The disc 1 6 The outer ring is fixedly mounted with a plurality of passive teeth 17, which mesh with the active teeth 15. A plurality of adjusting bodies 12 are fixedly mounted on the rotating shaft 11. The number of adjusting bodies 12 is consistent with the number of filter holes in a row of the filter element body 4. The adjusting bodies 12 are used to adjust the opening size of the filter holes. A protective cover 2 is fixedly mounted on the side of the placement plate 32 close to the single-chip microcomputer 31. The protective cover 2 is used to seal and protect the single-chip microcomputer 31. A plurality of supporting frames 34 are fixedly mounted on the outside of the placement plate 32. A plurality of supporting frames 34 are provided with notches 33 on the side close to the placement plate 32. The notches 33 are used for sealing the protective cover 2. The smart component 3 also includes a flow sensor 35. The flow sensor 35 is fixedly mounted on the side of the support frame 34 away from the single-chip microcomputer 31. There is a hollow hole inside the support frame 34. The flow sensor 35 is electrically connected to the single-chip microcomputer 31 through the hollow hole inside the support frame 34. The adjusting body 12 is spherical with a through hole.

[0025] The number of the driving teeth 15 is the same as the number of the disks 16 , and each driving tooth 15 controls the rotation of each disk 16 . When the driving teeth 15 rotate, the disk 16 is rotated via the driven teeth 17 , and the shaft 11 is rotated as well.

[0026] Since the motor 13 and the flow sensor 35 are both electrically connected to the single chip microcomputer 31 , the single chip microcomputer 31 can directly adjust and start and stop the motor 13 and the flow sensor 35 accordingly.

[0027] Among them, the flow sensor 35 is located at the outlet of the entire filtration capacity slow-release hydraulic return oil filter element, so the flow sensor 35 can monitor the flow and flow rate of the hydraulic oil passing through the hydraulic return oil filter element, and a flow rate threshold is set inside the flow sensor 35. When the flow rate decreases to a specific threshold, the adjustment body 12 rotates a certain angle to make the filter hole size outside the hydraulic return oil filter element larger, so that the flow rate of the hydraulic oil flowing through the hydraulic return oil filter element returns to the initial amount.

[0028] Since the driving teeth 15 are rotated by the rotation of the rotary disk 14 , and the disc 16 is rotated by the rotation of the driving teeth 15 , the rotation arc of each regulating body 12 is the same.

[0029] The working principle of the present invention is described below: When the filter capacity slow-release hydraulic return oil filter element is just replaced, the regulating body 12 is located at a certain angle inside the filter element body 4, so that the filter element body 4 can filter the hydraulic oil normally. At this time, the flow sensor 35 monitors the flow rate and flow rate of the hydraulic oil at all times. When many impurities are attached to the outside of the filter capacity slow-release hydraulic return oil filter element, the flow rate and flow rate of the hydraulic oil directly passing through the filter capacity slow-release hydraulic return oil filter element will decrease. At this time, the flow sensor 35 senses this situation and directly transmits an electrical signal to the single-chip microcomputer 31. After receiving the signal, the single-chip microcomputer 31 directly controls the motor 13 to start. The motor 13 causes the drive shaft 18 to rotate slightly, and directly causes the turntable 14 and the active gear 15 to rotate. The rotation of the active gear 15 will directly cause the passive gear 17 and the disc 16 to rotate, thereby causing the rotating shaft 11 to rotate slightly with the adjusting body 12. Since the adjusting body 12 is a sphere with a through-hole, when the adjusting body 12 rotates, it will be consistent with the principle of internal adjustment of the ball valve, making the size of the external filter hole of the filtration capacity slow-release hydraulic return oil filter element larger, thereby increasing the flow rate of the hydraulic oil through the filtration capacity slow-release hydraulic return oil filter element. When the amount of impurities attached to the surface of the filtration capacity slow-release hydraulic return oil filter element increases, the rotation amplitude of the adjusting body 12 also increases, thereby allowing the hydraulic return oil filter element to have the ability of slow-release filtration capacity on the basis of only a single filter mesh, greatly improving the practicality of using the filtration capacity slow-release hydraulic return oil filter element.

[0030] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
