Abstract
The invention discloses a threaded filter, which is characterized in that the threaded filter comprises a filter shell 1, a thread-type filter element 2, a closing ring 3, a liquid inlet 4 and a liquid outlet 5; the thread-type filter element 2 comprises an A liquid channel 6, a B liquid channel 7 and a filtering thread 8; wherein, the thread-type filter element 2 is arranged in the filter shell 1; the closing ring 3 is arranged at one side of the shell; two ends of the filter shell 1 are respectively communicated with the liquid inlet 4 and the liquid outlet 5. The threaded filter has the advantages that the threaded filter changes the traditional mode in which the liquid is filtered, has improved filtering performance, and thus can be applied to the liquid filtering system for fuel, lubricating oil and water supply, etc.
Description
Technical field
The present invention relates to mechanical field, a kind of thread filter is provided especially.
Background technology
In order to remove impurity such as particle in the liquid, silk, need to install filter in the liquid delivery system.At present, the filter of industrial general employing is the metal mesh structure filter, by adjusting the gap of wire netting, satisfies the requirement of different filtering accuracies.On structure, the filtration device structure relative complex of metal mesh structure, particularly filter core part for the fixing metal net, generally need the special metallic support of design.In use, the impurity that filters out is not easy to remove clean, impurity such as the silk that especially filters out, hair, hang over and remove difficulty more on the wire netting, and be easy to cause the damage of wire netting, if wire netting damages, filter will lose use value, the filter that have to more renew causes unnecessary waste.
Summary of the invention
The objective of the invention is in order to solve the structure relative complex that current metal mesh structure filter exists, the problem of aspects such as inconvenience cleaning provides a kind of thread filter especially.
The invention provides a kind of thread filter, it is characterized in that: described thread filter includes filter housings 1, screw-type filter core 2, collar 3, liquid inlet 4, liquid outlet 5; Screw-type filter core 2 includes the preceding fluid passage 6 of filtration, filters back fluid passage 7, filters screw thread 8; Wherein screw-type filter core 2 is packed in the filter housings 1, the housing one side collar 3 of packing into, and filter housings 1 two ends are communicated with liquid inlet 4 and liquid outlet 5 respectively.
Described thread filter, filter housings 1 is one of following version: cylindrical structural, rectangular configuration; Filter housings 1 is one of following version with the syndeton of external pipe: the conical surface seal structure that is threaded, bolted end face seal structure.
Described thread filter, the quantitative range of fluid passage 6, filtration back fluid passage 7 is before filtering: 2～30; Fluid passage 6 can be identical with the quantity of filtering back fluid passage 7 before filtering, also can be different.
Described thread filter, the diameter range 4～400mm of screw-type filter core 2 outside cylinder.
The thread filter structure is seen shown in Figure 1; Filter is made up of major parts such as filter housings 1, screw-type filter core 2, collars 3; Screw-type filter core 2 is packed in the filter housings, and the housing one side collar 3 of packing into prevents that filter core from skidding off; The filter housings two ends are connected with the pipeline of liquid system, form complete fluid filter system.
The structure of screw-type filter core is seen shown in Figure 2; This filter core is the metal processing structure, simple in structure, machining screw on the external cylindrical surface, fluid passage 6 and filtration back fluid passage 7 before axially processing is filtered on the face of cylinder, fluid passage 6 and to filter back fluid passage 7 spaced apart before filtering, interchannel leaves the part screw thread, and liquid is entered when filtering back fluid passage 7 by fluid passage 6 before filtering, need through screw thread, the impurity in the liquid will be leached by screw thread.Take out filter core for convenience, the center, two ends of filter core also is processed with screw thread, can be screwed into screw thread in the filter core by screw, takes out filter core.
As shown in Figure 2, after liquid enters filter, pass the core of collar, enter the screw-type filter core.The structure of screw-type filter core 2 is seen shown in Figure 3, after liquid is entered by fluid passage 6 before filtering, just can enter filtration back fluid passage 7 by the screw thread on the face of cylinder and also flow out.Liquid is by screw thread the time, and impurity such as the particle in the liquid, silk, hair will filter out, and stays in the preceding fluid passage 6 of filtration of screw-type filter core.After filter uses a period of time, rinse well and can continue to use, do not have the difficult phenomenon of cleaning of metal mesh structure filter.
Filter housings can be versions such as cylindrical, rectangle, and two ends are that the liquid import and export is installed the limit, and according to using needs, filter housings is installed the conical surface seal structure that the limit can be designed to be threaded, and also can be designed to bolted end face seal structure.
Before the filtration of screw-type filter core fluid passage 6 and filter the quantity of back fluid passage 7 can be 2～30 variations, quantity can be identical also can be different, select according to the actual needs of aspects such as fluid flow, structure.
The size of screw-type filter core 2 outside cylinder can be according to the requirement adjustment of aspects such as fluid flow, structural limitations, diameter range 4～400mm.
The requirement adjustment according to the liquid filtering precision of thread pitch size, the optional scope 0.2～8mm of pitch in particular cases, can process special screw thread and meet design requirement.
Advantage of the present invention: simple in structure, size is little, easy accessibility; Adjust the characteristic parameters such as outside dimension, thread pitch, fluid passage size and quantity of screw-type filter core, can satisfy the requirement of aspects such as different flow, filtering accuracy; Impurity on the screw-type filter core cleans up easily, the recycling rate of waterused height; Select different materials processing for use, can be applicable to the needs of aspect such as anticorrosion in the different liquids filter processes such as fuel oil, lubricating oil, water.
