Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a special filter element structure for a sealed hydraulic pump station. Background Art

[0002] Filter elements are mainly used in oil filtration, air filtration, water filtration and other filtration industries. Filter elements for hydraulic pump stations are an important part of the hydraulic system. Their main function is to filter and purify hydraulic oil to ensure the normal operation of the hydraulic system and extend the service life of the equipment.

[0003] In order to ensure the sealing of the fitting surfaces at both ends of the existing filter element, a large force is usually required to snap the filter element into place. As a result, when the filter element is disassembled, if the filter element is high, it is not convenient for personnel to exert a large pulling force upward when pulling the filter element upward for disassembly. Therefore, the filter element needs to be shaken back and forth for disassembly, which can easily damage the filter element and is not convenient for quick installation of the filter element when using less force. Utility Model Content

[0004] The utility model aims to provide a sealed filter element structure for a hydraulic pump station to solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A sealed filter element structure dedicated to a hydraulic pump station comprises a filter element, both ends of the filter element are movably provided with sealing components, the sealing components comprise sealing rings movably provided at both ends of the filter element, a sealing ring is movably provided inside the groove on the outer surface of the sealing ring, an adjusting component is movably provided in the groove on the outer surface of the sealing ring, the adjusting component comprises a fixing ring fixedly installed in the groove on the outer surface of the sealing ring, a rotating plate is rotatably connected to the outer side of the sealing ring on one side of the fixing ring, a plurality of No. 2 slide grooves are equidistantly provided on the surface of one side of the fixing ring, a slider is slidably connected inside the No. 2 slide groove, an arc-shaped push plate is fixedly installed on one end of the slider, and a connecting component is connected between the two adjusting components.

[0007] Furthermore, a plurality of arc grooves are provided at equal angles on one side surface of the rotating plate, one end of the sliding block passes through the second sliding groove and is slidably connected with the arc groove, and the outer wall of the arc push plate is fitted with the inner wall of the sealing ring.

[0008] Furthermore, the connecting assembly includes two cross plates movably arranged on the inner side of the sealing ring, a plurality of No. 1 slide grooves are formed at equal angles on the inner wall of the card slot on the outer side surface of the sealing ring, and the cross plate passes through the No. 1 slide groove and is fixedly connected to the rotating plate.

[0009] Preferably, a plurality of positioning seats are fixedly mounted on one side surface of the two cross plates, and a positioning rod is movably inserted between two symmetrical positioning seats.

[0010] Preferably, a rotating rod is fixedly passed through a surface of one side of the cross plate, and the rotating rod passes through a sealing ring at an upper end and is rotatably connected to the sealing ring.

[0011] Preferably, a fixing ear is fixedly installed at the upper end of the outer surface of the rotating rod, and a No. 1 bolt is screwed through the interior of the fixing ear.

[0012] Preferably: a clamping block is fixedly mounted on the surface of one end of the rotating rod, a clamping seat is fixedly mounted on the surface of one side of the cross plate, the clamping block is movably plugged into the clamping seat, a No. 2 bolt is screwed into one side of the clamping seat, and the No. 2 bolt passes through the clamping block and the clamping seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By turning the rotating rod, the two cross plates rotate synchronously, driving the rotating plate to rotate, providing power for the movement of the arc push plate. The insertion of the positioning rod and the positioning seat increases the stability of the two cross plates when they rotate synchronously. Then turn the No. 1 bolt to make it press against the sealing ring at the upper end to fix the rotating rod to prevent the rotating rod from rotating on its own, improve the firmness of the arc push plate, and thus increase the firmness of the filter element after installation.

[0015] 2. Rotate the rotating plate to make the arc groove push the slider to slide inside the No. 2 slide groove, adjust the position of the arc push plate, and when the arc push plate moves outward, increase the extrusion force of the sealing ring to the outside, so that the filter element is installed more tightly, thereby reducing the force used when installing the filter element, making it easier to install. Conversely, when the arc push plate moves inward, the extrusion force of the sealing ring to the outside is reduced, reducing the friction between the sealing ring and the equipment installation surface, so that when the filter element is installed at a high height, personnel can easily pull up to remove the filter element, so as to avoid damage to the filter element caused by shaking it back and forth for removal due to insufficient removal force, making the filter element easier to remove.

[0016] 3. Twist the No. 2 bolt to separate it from the block, pull down the sealing ring at the lower end, and disassemble the sealing ring to facilitate maintenance. At the same time, when the sealing ring is damaged, the sealing ring can be removed from the slot on the outside of the sealing ring through its own elastic force and directly replaced, thereby facilitating the replacement and maintenance of a single component and reducing replacement costs.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5 In the embodiment of the utility model, a sealed filter element structure dedicated to a hydraulic pump station includes a filter element 1, both ends of the filter element 1 are movably sleeved with sealing components 2, the sealing component 2 includes a sealing ring 201 movably sleeved on both ends of the filter element 1, a sealing ring 203 is movably sleeved inside the card groove on the outer surface of the sealing ring 201, an adjusting component 3 is movably provided in the card groove on the outer surface of the sealing ring 201, the adjusting component 3 includes a fixing ring 301 fixedly installed in the card groove on the outer surface of the sealing ring 201, a rotating plate 303 is rotatably connected to the outer side of the sealing ring 201 at one side of the fixing ring 301, a plurality of No. 2 slide grooves 302 are equidistantly provided on the surface of one side of the fixing ring 301, a slider 305 is slidably connected inside the No. 2 slide groove 302, an arc-shaped push plate 306 is fixedly installed at one end of the slider 305, and a connecting component 4 is connected between the two adjusting components 3.

[0025] Specifically, the slider 305 pushes the arc-shaped push plate 306 to move, squeeze and fit the sealing ring 203, increase or reduce the squeezing force of the sealing ring 203 toward the outside, so that the sealing ring 203 can be easily installed and removed from the installation fitting surface.

[0026] Embodiment 1

[0027] like Figure 3 As shown, in this embodiment, a plurality of arc grooves 304 are opened at equal angles on one side surface of the rotating plate 303, one end of the sliding block 305 passes through the second sliding groove 302 and is slidably connected to the arc groove 304, and the outer wall of the arc push plate 306 is in contact with the inner wall of the sealing ring 203.

[0030] During the specific implementation, the rotating rod 401 is turned to make the two cross plates 404 rotate synchronously, driving the rotating plate 303 to rotate, providing power for the movement of the arc-shaped push plate 306, and the insertion of the positioning rod 406 and the positioning seat 405 increases the stability of the two cross plates 404 when rotating synchronously. Then, the No. 1 bolt 403 is turned to make it press against the sealing ring 201 at the upper end, fix the rotating rod 401, prevent the rotating rod 401 from rotating on its own, improve the firmness of the arc-shaped push plate 306, and thus increase the firmness of the filter element 1 after installation.

[0031] Embodiment 2

[0032] On the basis of the first embodiment, in order to solve the problem that the sealing ring 201 in the first embodiment is inconvenient to replace and repair.
