Abstract

The utility model discloses a centrifugal liquid filter. The utility model is characterized in that the interior of a separating cavity of a separator is provided with a guiding disk, and the bottom end of the separating cavity is provided with at least two valves. The lower end of a casing body is also provided with sewage draining openings corresponding to the valves, and the interior of the casing body outside the separating body is provided with a spacer ring. The filter cancels a filtering net, and the utility model has quick filtration as well as avoids probability of generating the pollution for liquid caused by the filtering net or a permeable membrane. The filtration effect can achieve more than 99 percents. The utility model can be used for high-grade purification of mineral water, drinking water, various beverages and vines as well as purification of various non-combustible chemical liquids and sewage treatment.

Description

Centrifugal liquid filtering machine

The utility model relates to the equipment of filter liquide, specifically a kind of centrifugal liquid filtering machine.

Existing filter apparatus for filtering liquid can be divided into following a few class substantially:

A, filter net type, no matter take which kind of material technically, still the variation in material and aperture can only be worked in certain scope, can't filtering less than the impurity in aperture, though reached very high precision, be that the rate of filtration is slow on the one hand that as the permeation filtration of new technology all existing on the other hand may to the pollution again that is produced in various degree by the filter body.

B, centrifugal filtration technology have begun development, passive type filter as the lubrication oil filtration that among a small circle, is used for engine, it adopts liquid is imported from the center, liquid recoil strength by the nozzle ejection, the rotor of filter is rotated to be filtered, the deficiency of this equipment is that filtration yield is little, and filter effect is undesirable.

C, distillating filtering range of application only are suitable for pure water and some professional skill fields, and distillation can make the mineral matter in the water influence the standard of drinking water with plain being trapped of trace nothing, along with the attention of people, how can easily and effectively sewage disposal be become undrinkable water to become the technical issues that need to address in addition to environmental protection.

The purpose of this utility model is on the basis of existing technology, and a kind of centrifugal liquid filtering machine easily and effectively is provided.

The utility model is to adopt the separator of rotation at a high speed, make liquid and impurity wherein produce weight difference, make its isolation of purified by dividing technology, concrete technical scheme is as follows: a kind of centrifugal liquid filtering machine, it mainly comprises motor and is connected with motor and sends into transmission centrifugal device in the housing, place the separator in the housing, place the charging aperture of case top and the discharging opening of housing bottom, it is characterized in that: in the disengagement chamber of separator, positioning disk is housed, in the bottom of disengagement chamber two valves are housed at least, also be provided with and the corresponding sewage draining exit of valve in the housing lower end, a space ring is set in the housing outside disengagement chamber.

The utility model application of pure centrifugation technique is purified liquid, saved filter screen, not only the rate of filtration is fast, and the pollution of having avoided filter screen or permeable membrane that liquid is produced may, filter effect can reach more than 99%, this filter has wide range of applications, it not only can be used for comprising in the beverage liquid such as drinking water with water as medium, mineral water, the senior purification of various beverages and wine, also can be used for impurity filtering,, and can in to sewage disposal, bring into play its effect with the raising product purity to the various chemical liquids of non-combustible, complete machine structure is simple, the filter efficiency height; Operation and Maintenance is all very convenient.

Fig. 1 is a structural representation of the present utility model

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprises motor 12 and drives and send into transmission centrifugal device in the housing 1 by motor 12, match with housing 1 and to merge the separator 2 place in it, place the charging aperture 7 of case top, with the discharging opening 6 that is positioned at housing bottom, the profile of housing 1 is approximated to butterfly, one fixed mount 16 is housed in the lower end of housing 1, motor 12 is fixed on the fixed mount 16, and can in certain scope, move on the crossbeam of fixed mount as required, driving belt 13 is connected with the axle 9 of motor output shaft and separator respectively, be into font in that the section of the charging aperture of case top is approximate, the lower end that is positioned at charging aperture 7 in separator 2 also is provided with impeller 4, in the disengagement chamber 17 of separator 2, positioning disk 14 is housed, positioning disk in disengagement chamber is inverted plate-like, in order to make liquid produce eddy current, strengthen the weight difference of liquid and impurity, quicken separation therebetween, edge at positioning disk also is provided with at least two auxiliary air separators 8, it is shaft-like or banded that auxiliary air separator can be, at least be provided with two valves 3 in the bottom of disengagement chamber 17, valve 3 adopts mechanical flow-limiting valve or intermittent valve, flow-limiting valve is a valve of freely opening, it is according to filtering different liquid, limit different discharge capacitys, be generally and be lower than 10% of charging aperture liquid, intermittent valve discharges for opening valve at regular intervals automatically, consider from the angle of spin balancing, the setting of valve distributes by Equal round, also be provided with and the corresponding sewage draining exit 5 of valve in the bottom surface of housing 1, one space ring 11 is set in the housing outside disengagement chamber, in order to improve the effect of filtration, the space ring 11 that is provided with in housing will be higher than the discharge gate 10 of filter, and leave certain clearance with separator, this space ring is in housing, separator forms collecting bin 15 outward, (also is housing bottom) in the collecting bin bottom and has two discharging openings 6 at least.

The course of work of the present utility model is: the power of motor 12 drives decoupler shaft 9 by motor shaft by driving belt 13, make separator 2 rotation at a high speed in the housing 1 of filter, liquid material is entered in the separator by impeller 4 by charging aperture 7, positioning disk 14 makes liquid material flow to disengagement chamber 17, when rotated under the action of centrifugal force of Chan Shenging, liquid and impurity produce weight difference, and make liquid produce eddy current by auxiliary air separator 8, the weight difference of liquid and impurity progressively strengthens, the effect of centrifugal force and the free drop of object makes liquid and impurity begin shunting, when flowing to the disengagement chamber bottom, weight difference has made liquid and impurity produce visibly different distributed areas, the distribution of liquid level is positioned at disengagement chamber upper strata and inwall place, impurity then is positioned at the bottom and the outer wall place of disengagement chamber, impurity, dirt concentrates on sewage draining valve 3 places of separator gradually, discharge (or intermittently impurity being discharged during valve opening) separator 2 through the current limliting valve, and discharge by sewage draining exit 5 places, the liquid that purifies is under the continual situation of feed, in disengagement chamber 17, flow to discharge gate 10 continuously, discharge from discharging opening 6 through collecting bin 15.
