Abstract
The utility model discloses a filtering device. Liquid inlet pipeline is connected with a liquid inlet of a filter. Liquid outlet pipeline is connected with a liquid outlet of the filter. A pressure difference controller is arranged between the liquid inlet pipeline and the liquid outlet pipeline. The pressure difference controller detects the pressure difference between the liquid before and after filtering, thereby determining use state of a filter core. When the pressure difference controller detects a fact that the pressure difference reaches 0.1Mpa, the filter core in the filter is changed. The use state of the filter core in the filter is determined according to the pressure difference between the liquid before and after filtering through the pressure difference controller. Thus the use state of the filter core can be determined in real time without opening the filter, thereby changing the filter core in time and improving production efficiency and cleaning quality.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of filter that detects the filter core operating position.
Background technology
Filter is to carry indispensable a kind of device on the fluid media (medium) pipeline, is installed in the entrance point of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment usually, is used for stoping the impurity in the medium to enter, with the normal use of protection valve and equipment.When fluid enter be equipped with the certain specification filter core after, its impurity is blocked, the cleaning filtrate then discharged by filter outlet.
But in clean producing because filter core in filter interior, can't directly be confirmed the degree of injury of filter core, can not be timely renew cartridge more, cause filter effect undesirable, operating efficiency is not high, it is further that influence is normal produces.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of filter, its objective is fast, effectively, simply detects the filter element operating position, aborning can be in time renew cartridge more, increase work efficiency, production can be carried out smoothly.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of filter, input duct connects the inlet of filter, and the fluid pipeline connects the liquid outlet of filter, is equiped with differential pressure controller between input duct and the fluid pipeline, and differential pressure controller detects before the filtration and the fluid pressure differential after filtering.
Pass through technique scheme, a kind of filter described in the utility model, according to before filtering and the pressure reduction that filters back liquid judge whether needs are changed for filter core in the filter, under the situation that need not open filter, just can judge the operating position of filter core like this, enhance productivity and and filter effect, filter core cleans in time, and production is carried out smoothly.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the schematic diagram of a kind of filter of the utility model embodiment;
The represented corresponding component title of numeral among the figure:
1. input duct 2. filters 3. fluid pipelines 4. differential pressure controllers
5. the liquid outlet of inlet 6. filters of filter
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of filter, to be pending liquid enter filter by the inlet of filter to its principle, impurity in the liquid is deposited on the filter core, just discharge from the liquid outlet of filter through the liquid after the filtration treatment then, before this spline filter and the liquid after filtering just produced pressure reduction, differential pressure controller detects its pressure difference, judges the operating position of filter core.
Below in conjunction with embodiment and the specific embodiment the utility model is described in further detail.
Embodiment:
As shown in Figure 1, the input duct 1 of the utility model filter connects the inlet 5 of filter, and fluid pipeline 3 connects the liquid outlet 6 of filter, is equiped with differential pressure controller 4 between input duct 1 and the fluid pipeline 3.Liquid to be filtered enters filter 2 by input duct 1 from the inlet 5 of filter, and the impurity in the liquid is deposited in the filter core, and the liquid after the filtration flows to fluid pipeline 3 from the liquid outlet 6 of filter; Because the impurity in the liquid has been stayed in the filter core, before filtering and the liquid after filtering will form pressure reduction, can detect its pressure difference by differential pressure controller 4, so just can judge whether more renew cartridge by differential pressure controller 4, when pressure difference reaches 0.1MPa, change the filter core in the filter 2.
The utility model has been installed a differential pressure controller 4 more on common filter, the pressure reduction of the forward and backward liquid of utilization filtration judges whether to change the filter core in the filter 2, and just not needing to open filter 2 observes the filter core operating position.The operating position of so direct real-time monitored filter core, thus can be in time renew cartridge more, guarantee excellent cleaning effect, enhance productivity, production can normally be carried out smoothly.
To the above-mentioned explanation of disclosed a kind of filter embodiment, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
