Abstract
The utility model relates to a filter that is used on the liquid inlet of a sprayer, and pertains to the technical field of fluid purification facilities. The filtering channel of the filter comprises a filter body and a filter base, with a filter element as the filter part. The filter base is in cylindrical form, with the filter body with a liquid inlet and a liquid outlet mounted on the filter base, a tubular filter element mounted in the middle of the filter base, and a drain port is arranged on the bottom of the filter base. The top port of the filter element is open to the liquid inlet, and the bottom port of the filter element is open to the drain port on the bottom of the filter base; the cavity between the filter base and the filter element is open to the liquid outlet. When the blow-down valve mounted on the drain port on the bottom of the filter base is in open state, the liquid will flow through the liquid inlet into the filter, and then flow through the filtering element and flow out from the drain port on the bottom of the filter base, so that the filth left in the filtering element will be removed with the liquid; therefore, the filter element can be cleaned automatically, without taking out the filter element. The utility model implements automatic cleaning of filter element, and has advantages including easy operation and low pressure loss.
Description
Technical field
The utility model relates to a kind of filter, and especially a kind of filter that is applied in the injection apparatus inlet belongs to fluid purification facility technology field.
Background technology
Filter is one of critical piece in the liquid pipeline system, is installed in the entrance point of working line or injecting-unit usually.Existing filter is equipped with filtration members in fluid passage---filter membrane or screen pack, thus the particulate contamination in can the filtering liquid pipeline system is avoided pipeline blockage, guarantees that pipeline is unimpeded.
Understand according to the applicant, the existing following problem of filter ubiquity: 1, filter area is little, resistance is big, therefore causes crushing big; 2, filter membrane or screen pack stop up easily, clean inconvenience.
Summary of the invention
The purpose of this utility model is: at the shortcoming that above prior art exists, it is little and clean low pressure loss self-cleaning strainer very easily to propose a kind of resistance.
In order to reach above purpose, low pressure loss self-cleaning strainer of the present utility model comprises filtration channel and filtration members, and described filtration channel is made up of filtering bodies and filtering base, and described filtration members was a filter core.Described filtering base is tubular, and the upper end fixed installation is shaped on the filtering bodies of inlet and liquid outlet, and the middle part fixedly mounts the filter core of crossing of tubulose, and the bottom is shaped on sewage draining exit.The described upper port of crossing filter core is communicated with inlet, and lower port is communicated with the sewage draining exit of filtering base bottom, and described filtering base is communicated with liquid outlet with the chamber of crossing between the filter core.
When the blowoff valve of installing when filtering base bottom blow-down mouth place cut out, liquid will be through filter element filtering behind the inlet inflow filter, and liquid enters filtering base and flows out from liquid outlet behind the chamber between the filter core excessively, and impurity is detained in crossing filter core.When the blowoff valve of installing when filtering base bottom blow-down mouth place is opened, liquid will flow out through the sewage draining exit of filter core from the filtering base bottom behind the inlet inflow filter, the impurity of being detained in crossing filter core is cleaned discharge thereupon, thereby need not take out filter core, can self-cleaningly clean, very convenient.While is because the filter core of crossing of the present utility model has columniform large tracts of land filtering surface, so resistance is little, and is also little to the crushing of whole pipeline.
In a word, the utility model has realized crossing the self-cleaning cleaning of filter core, and have easy and simple to handle, advantage that crushing is little.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Embodiment one
The low pressure loss self-cleaning strainer of present embodiment mainly is made up of filtering bodies 1, filtering base 5, mistake filter core 3.Filtering base 5 is tubular, and the upper end is by being threaded, and fixed installation is shaped on the filtering bodies 1 of horizontal inlet and liquid outlet, the filter core 4 excessively of middle part fixed installation tubulose, and the bottom is shaped on sewage draining exit.The upper/lower terminal of crossing filter core 4 is inlaid in respectively in the interface 3, and last end interface is communicated with filtering bodies 1 inlet, and following end interface is communicated with the sewage draining exit of filtering base 5 bottoms.Blowoff valve 6 is equipped with at the sewage draining exit place.Form tubular chambers between filtering base 5 and the mistake filter core 4, this chamber is communicated with the liquid outlet of filtering bodies 1.
When blowoff valve 6 cut out, liquid saw through filter core 4 behind the inlet inflow filter, entered the chamber between filtering base 5 and the mistake filter core 4, flowed out from liquid outlet, and impurity is detained in crossing filter core 4.When blowoff valve 6 was opened, liquid was behind the inlet inflow filter, and the impurity that will be detained in crossing filter core 4 washes, and discharges from blowoff valve 6.
The filter area of the low pressure loss self-cleaning strainer of present embodiment is 10～20 times of pipeline area of passage, its compact conformation, and flow resistance is little, and blowdown is convenient.Have following outstanding advantage:
1, can be according to different requirements, the screen pack of the various order numbers of adapted;
2, open the self-cleaning cleaning that blowoff valve can be finished filter fast;
3, filter area has greatly obviously reduced the pressure loss of filter;
4, can adopt different designs height and width easily according to various operating positions.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
