Description
Technical field
This utility model relates to one can drain filter.
Background technology
In pump-storage generator, cooling system is particularly important; guarantee that unit can run continually and steadily, but cooling water takes from nature water body in lake, can infiltrate some foreign material unavoidably; foreign material such as unit cooler; cooler then may be made to block, have a strong impact on cooling effect, the rising of unit temperature causes parts impaired; therefore water is filtered; filtering off the foreign material in water, existing filter is poor without dirt eliminating function or pollution discharge capability, and filter easily blocks self.
Summary of the invention
The purpose of this utility model be to provide one can drain filter, solve technological deficiency poor without pollution discharge capability or pollution discharge capability in prior art.
For solving the problems referred to above, technical solution adopted in the utility model is:
One can drain filter, including filter body, described filter body is the hollow structure of up/down perforation, the top of filter body is water inlet, bottom is outlet, in described filter, filter element is set, filter element is the top seal of hollow structure and filter element, the bottom opening of filter element and communicating with the outlet of filter body, the bottom of filter element fits with filter body inwall, filter element outer wall constitutes open-topped inner chamber with the inwall of filter body, filter element top has for moisture in filter body flows to the through hole within filter element, the outer surface of filter element is provided with helical blade from top to bottom, the bottom of filter body has sewage draining exit, the height of sewage draining exit is more than or equal to the height of filter element with filter body joint place.
Sewage is entered in filter body by water inlet, owing to being provided with helical blade on filter element, rotational flow after rain in sewage entrance filter body, the current rotated prevent foreign material from pasting on filter element outer wall, improve filter efficiency, impurity is pushed into filter bottom simultaneously, water is entered inside filter element by the through hole on filter element top, through hole filters off the foreign material in water, and discharge from the bottom of filter element, when impurity is piled up more bottom filter body, open the valve at sewage draining exit, the current rotated are carried impurity and are discharged by impurity by sewage draining exit, in this utility model, foreign material can not enter inside filter element, only water can enter filter element by the through hole on filter element, thus realize water and magazins' layout, in this utility model, through hole is opened in the top of filter element, prevent owing to the degree of depth of water is excessive, pressure is relatively big and in impurity is pressed into filter element or blocking through hole.This utility model owing to sewage draining exit is in the bottom of filter body, above the pressure effect of water force impurity to be discharged from sewage draining exit, pollution discharge capability is strong.
As further improvement of the utility model, the bottom of described filter element is up-small and down-big horn-like, and filter element bottom sides is along fit with filter body inwall and interfix, and the height of described sewage draining exit is more than the height bottom filter element.
The bottom of filter element is horn-like, and little bottom, top is big, presents an inclined-plane bottom filter element, and impurity is prone to slide to sewage draining exit on inclined-plane, facilitates impurity to discharge, and does not has foreign material to pile up at filter element.
The beneficial effects of the utility model are: this utility model is by arranging filter element in filter body, water and foreign material are discharged from filter body by different passages, realize the separation of water and foreign material, filter element arranges helical blade, current enter rotational flow after filter body, impurity is avoided to paste at filter element outer wall, it is achieved the automatically cleaning effect of filter element.

Fig. 1 is structural representation of the present utility model.
Wherein: 1, filter body；2, water inlet；3, outlet；4, filter element；5, through hole；6, helical blade；7, sewage draining exit.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.
nullAs shown in Figure 1 can drain filter，Including filter body 1，Described filter body 1 is the hollow structure of up/down perforation，The top of filter body 1 is water inlet 2，Bottom is outlet 3，Filter element 4 is set in described filter，Filter element 4 is the top seal of hollow structure and filter element 4，The bottom opening of filter element 4 and communicating with the outlet 3 of filter body 1，The bottom of filter element 4 fits with filter body 1 inwall，Filter element 4 outer wall constitutes open-topped inner chamber with the inwall of filter body 1，Filter element 4 top has for moisture in filter body 1 flows to the through hole 5 within filter element 4，The outer surface of filter element 4 is provided with helical blade 6 from top to bottom，The bottom of filter body 1 has sewage draining exit 7，The height of sewage draining exit 7 is more than or equal to the height of filter element 4 with filter body 1 joint place.
The preferred filter element of this utility model with the fixed form of filter body 1 is: the bottom of described filter element 4 is up-small and down-big horn-like, filter element 4 bottom sides is along fitting with filter body 1 inwall and interfix, and the height of described sewage draining exit 7 is more than the height bottom filter element 4.
During use, first close the valve of sewage draining exit 7, sewage enters in filter body 1 from water inlet 2, and it is rotating by helical blade 6 and flows downward, water enters in filter element 4 from the through hole 5 on filter element 4 top, flow out bottom filter element 4, and finally flowed out by outlet 3, foreign material then can not be by the through hole 5 on filter element 4, being filtered, foreign material are precipitated to downwards the junction of filter element 4 and filter body 1, when gear foreign material are stacked into a certain amount, open the valve of sewage draining exit 7, foreign material are discharged from sewage draining exit 7.
This utility model and electromagnetic valve and differential pressure measurement system, with the use of, opening and closing by electromagnetic valve control of sewage disposal mouth 7, can realize automatic blowdown function.
All this utility model description are prior art for be specifically noted or be capable of by existing technology; should be understood that; for those of ordinary skills; can be improved according to the above description or be converted, and all these modifications and variations all should be belonged to the protection domain of this utility model claims.
