Description
Technical field
The utility model belongs to art of filters, is specifically related to a kind of negative pressure filter.
Background technology
In the filter process of oils or other thick liquids, usually liquid-inlet supercharging is needed, filter course is passed through smoothly to make liquid to be filtered, but this situation needs to provide pressure in addition, and voltage supply can not suspend in whole filter process, not only need to expend the energy, and very large noise pollution can be caused.
Summary of the invention
For solving the problem, the utility model discloses a kind of negative pressure filter, with by the problem solving the energy waste environmental pollution that lasting voltage supply brings.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of negative pressure filter, comprise filter body, holding vessel and catheter, be negative pressure in described holding vessel, holding vessel crown center connects catheter one end, the described catheter other end connects in the middle of the bottom of filter body, on the left of described filter body outside top, feed tube is set, top right side arranges turnover tracheae, the mouth of a river is set out bottom filter body external right side, filter body internal upper part arranges non-woven fabrics filtering layer, active carbon filtering layer is set gradually under described non-woven fabrics filtering layer, fine filtering layer, drainage layer, between described fine filtering layer and drainage layer, hollow layer is set, below the corresponding hollow layer of described delivery port.
Improve as one of the present utility model, described nonwoven layer is at least three layers of non-woven fabrics composition.
Improve as one of the present utility model, described nonwoven layer is that non-woven fabrics is folded with.
Improve as one of the present utility model, described fine filtering layer is ETFE film.
Improve as one of the present utility model, described drainage layer is hydrophobic membrane filtration.
Improve as one of the present utility model, described catheter is arranged valve one.
Improve as one of the present utility model, described holding vessel and catheter are that nut is connected.
Improve as one of the present utility model, described feed tube and turnover tracheae arrange valve two.
The beneficial effects of the utility model are:
A kind of negative pressure filter described in the utility model, the holding vessel of negative pressure is connected on filter body, pressure reduction is utilized to suck in holding vessel by the liquid in filter body, do not need to be continuously liquid carrying for pressure, layered filtration layer in filter body, from coarse to finely can filter out the impurity in liquid, finally water can be separated and be retained in hollow layer, then utilize delivery port to discharge, after holding vessel has been expired, the pressure in the turnover adjusted filter body of tracheae and holding vessel can be utilized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numerals list:
1. filter body, 2. holding vessel, 3. catheter, 4. feed tube, 5. pass in and out tracheae, 6. non-woven fabrics filtering layer, 7. active carbon filtering layer, 8. fine filtering layer, 9. drainage layer, 10. hollow layer, 11. delivery ports.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
As shown in the figure, a kind of negative pressure filter, comprise filter body 1, holding vessel 2 and catheter 3, be negative pressure in described holding vessel 2, holding vessel 2 crown center connects catheter 3 one end, and described catheter 3 other end connects in the middle of the bottom of filter body 1, utilizes negative pressure in holding vessel 2, liquid in filter body 1 can be sucked holding vessel 2, not need to provide power source to make liquid pass through filter course in addition.
As shown in the figure, filter body 1 internal upper part arranges non-woven fabrics filtering layer 6, described non-woven fabrics filtering layer sets gradually active carbon filtering layer 7, fine filtering layer 8, drainage layer 9 for 6 times, described nonwoven layer 6 is at least three layers of non-woven fabrics composition, nonwoven layer 6 is folded with for non-woven fabrics, described fine filtering layer 8 is ETFE film, and described drainage layer 9 is hydrophobic membrane filtration, and non-woven fabrics filtering layer 6 can be considered to be worth doing and larger particles impurity by filtering metal; Active carbon filtering layer 7 adsorbs granule, the adsorbable more fine particle of fine filtering layer 8, drainage layer 9 separable go out moisture in liquid to be filtered.
As shown in the figure, between described fine filtering layer 8 and drainage layer 9, hollow layer 10 is set, temporarily can preserve the moisture that drainage layer 9 is separated, the mouth of a river 11 is set out bottom filter body 1 external right side, below the corresponding hollow layer 10 of described delivery port 11, delivery port 11 arranges valve, utilizes delivery port 11 can get rid of moisture in hollow layer 10 in time.
As shown in the figure, on the left of described filter body 1 outside top, feed tube 4 is set, feed tube 4 is the entrance of oils or other thick liquids, feed tube 4 is outer not to be needed to arrange supercharging mechanical, top right side arrange turnover tracheae 5, for pressure in adjusted filter body 1 and holding vessel 2, when filter after liquid full holding vessel 2 time, turnover tracheae 5 release pressure can be opened, can move smoothly and change holding vessel 2.
As shown in the figure, described catheter 3 arranges valve one, described holding vessel 2 is connected for nut with catheter 3, prevents overflow, also can negative pressure release in holding vessel.
As shown in the figure, described feed tube 4 and turnover tracheae 5 arrange valve two, and liquid is in filter process, and feed tube 4 generation opens, and turnover tracheae 5 is closed, and delivery port 11 is opened, then the valve closing on catheter 3, the valve open on turnover tracheae 5.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic.
