Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
Description of drawings
The hydraulic pipeline filter structural representation that accompanying drawing 1 provides for the utility model;
Accompanying drawing 2 is the structural representation of cartridge filter;
Accompanying drawing 3 is a cold bed lifting hydraulic schematic diagram, also is that hydraulic pipeline filter is used installation diagram.
Embodiment
As shown in drawings: a kind of hydraulic pipeline filter, it comprises the cylindrical housing 3-1 of a both ends open, the end of shell 3-1 is provided with a hard pipe joint 3-10, hard pipe joint 3-10 and shell 3-1 weld together, hard pipe joint 3-10 is provided with hydraulic pressure oilhole 3-9, and the oil inlet hole of hydraulic pressure oilhole 3-9 and hard pipe joint 3-10 communicates.The other end of shell 3-1 is provided with internal thread, the threaded end of shell 3-1 is connected with the hose coupling 3-4 of a bracelet pressure type nut 3-6, the junction plane of circle is provided with an O RunddichtringO 3-3 in hose coupling 3-4 cylindrical and the shell 3-1, and the connecting end of hose coupling 3-4 and flexible pipe also is provided with an O RunddichtringO 3-5.Inner chamber at shell 1 is provided with a cartridge filter 3-7, the end of cartridge filter 3-7 withstands on the oil inlet hole of hard pipe joint 3-10, oil inlet hole sealing with hard pipe joint 3-10, make hydraulic oil can only enter the inner chamber of shell 3-1 from the hydraulic pressure oilhole 3-9 on the hard pipe joint 3-10, the other end of cartridge filter 3-7 and hose coupling 3-4 are by being threaded togather.Like this, formed two hydraulic fluid chambers in the shell 3-1 of hydraulic pipeline filter, one is the hydraulic fluid chamber 3-2 that forms between shell 3-1 inwall and the cartridge filter 3-7 outer wall, and one is the hydraulic fluid chamber 3-8 that cartridge filter 3-7 inner chamber forms.
Described cartridge filter 3-7 is made up of filter screen joint 3-7-1, urceolus 3-7-3, inner core 3-7-4 and metal screen 3-7-2, urceolus 3-7-3 is the cylinder that one one end seals an end opening, inner core 3-7-4 is the cylinder of a both ends open, the barrel of urceolus 3-7-3 and inner core 3-7-4 is provided with filtering hole, inner core 3-7-4 is located in the urceolus 3-7-3, metal screen 3-7-2 is located between the outer wall of the inwall of urceolus 3-7-3 and inner core 3-7-4, and filter screen joint 3-7-1 is fixed on the opening end of urceolus 7-3 and inner core 7-4.
The hydraulic pipeline filter that the utility model provides is used in the 90T of Hengyang tandem rolling pipe Co., Ltd electric furnace-100T refining furnace and VD stove-four machine four stream caster machine production line hydraulic systems, has obtained good effect.Casting machine cold bed collection blanking device in this production line adopts hydraulic system to drive, and the cold bed elevating system adopts synchronous fuel tank and eight hoist cylinders to carry out the lifting synchronous drive.In the production process, the cooling-bed hydraulic system often breaks down, and failure cause mainly is because hoist cylinder Sealing and piston damage, and pipeline pollutant occurs and brings the synchronous valve platform into, causes each hydraulic element card of valve platform to stop and lost efficacy.
Cold bed lifting hydraulic schematic diagram as shown in Figure 3, it comprises eight hoist cylinders 1, synchronous valve platform 5 and synchronous fuel tank 6.From accompanying drawing 3 as can be known, the rodless cavity of eight hoist cylinders 1 of cold bed and synchronous fuel tank 6 have formed one " choke-out cavity volume " between (comprising synchronous fuel tank inside), this a part of fluid discord system hydraulic station of rodless cavity-pipeline-valve platform-synchronous fuel tank carries out circulating filtration (or circular flow is minimum), has only by safety valve 7 and lets out oil sump tank.Hoist cylinder 1 is because environment is abominable, operating mode is poor, reasons such as machinery installation form, after hoist cylinder 1 inner carrier or the bad seals, pollute fragment directly from entering pipeline and synchronous fuel tank 6, because this zone is equivalent to one " choke-out cavity volume ", if then these pollutions are not carried out system's clean cycle and just can't thoroughly be handled totally, even handle clean, because the abominable working environment of hoist cylinder, still may duplicate problem later on, thereby the frequent card of the hydraulicdirectional control valve 8 (Vickes product) that causes Hydraulic Synchronizing Valve platform 5 is stopped, make system's cisco unity malfunction, the cold bed paralysis is affected the rhythm of production of electric furnace continuous casting.
After the hydraulic pipeline filter that the utility model provides has been installed on flexible pipe 2 lower ends of cold bed hoist cylinder 1 and the hard tube 4 between the synchronous valve platform 5, hard tube 4 and synchronous fuel tank 6 that pollution fragment in the hoist cylinder 1 enters synchronous valve platform 5 have been got rid of, hydraulicdirectional control valve 8 in the Hydraulic Synchronizing Valve platform 5 is not blocked stop, guarantee that cold bed can proper functioning.
