The utility model provides an enough provide the activated carbon filter of more outstanding filter effect.

Description

A kind of efficient active carbon filter

Technical field

This utility model relates to a kind of filter, more specifically, it relates to a kind of efficient active carbon filter。

Background technology

Filter is indispensable a kind of device on pumped (conveying) medium pipeline, plays the medium to pipe interior flowing and is filtered the effect of remove impurity。

At present, industrial large-scale defecator on the market, the principle of its filtration being easily understood very, have employed multistage filtering net, thus being filtered by the impurity in medium。And existing these defecators, basic adopt activated charcoal strainer that impurity is filtered, active carbon filter screen is paved with the cross section of whole pipeline, so that the liquid flowing through this filter screen is filtered。This simple filter type, often can not get extraordinary filter effect, it is therefore desirable to have the better efficient active carbon filter of a kind of filter effect。

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of active carbon filter that can provide more outstanding filter effect。

For achieving the above object, this utility model provides following technical scheme: a kind of efficient active carbon filter, including water inlet, shell, outlet, multi-stage activated carbon filtration structure net and quartz sand filtration net, described outer casing bottom center has been horizontally disposed with propeller, the first filter screen group it is disposed with from top to down above described propeller, second filter screen group and the 3rd drainage screen group, described first filter screen group, second filter screen group and the 3rd filter screen group are provided with two-layer, its cross section of filter screen being positioned at lower floor is disposed as arrowhead form, described arrow tip is downward, described lower screen is more thick the closer to tip place thickness。

This utility model is further arranged to: the thickness of the lower screen center of described first filter screen group is more than the thickness of the lower screen center of the second filter screen group, and the thickness of the lower screen center of described second filter screen group is more than the thickness of the lower screen center of the 3rd filter screen group。

This utility model is further arranged to: its cross section of filter screen being positioned at upper strata in described first filter screen group, the second filter screen group and the 3rd filter screen group is disposed as arrowhead form, and upwards, the tip of described tip and lower screen is in same upright position to described tip。

This utility model is further arranged to: described first filter screen group, the second filter screen group and the 3rd filter screen group are positioned at upper strata its covering of filter screen area is the filter screen area coverage being positioned at lower floor 1/4th。

By adopt technique scheme, be positioned at bottom propeller rotate, cause whole filter interior liquid can both by its drive do regular clockwise or counterclockwise。And when liquid so rotates in filter interior time, the impurity of liquid internal relative to being partial to the center rotated, can be drawn close to center of rotation。(this point can prove simply by testing, and in a teacup, piles water, Folium Camelliae sinensis on bubble, then stirs uniformly clockwise or counterclockwise with chopsticks, it has been found that Folium Camelliae sinensis is all drawn close to center of rotation。) so relative, filter ratio that whole active carbon filter is relatively common, with regard to many steps that impurities in liquid is assembled, first assemble, refilter。This makes it possible to improve the filter efficiency of whole filter。

Detailed description of the invention

With reference to Fig. 1, this utility model one efficient active carbon filter embodiment is described further。

A kind of efficient active carbon filter as shown in Figure 1, including water inlet 2, shell 1, outlet 3, multi-stage activated carbon filtration structure net and quartz sand filtration net。Need the liquid filtered to enter filter from water inlet 2, flow out from outlet 3 through filtering。At the center of filter interior, it is provided with a fixing axle 9, and the bottom level of this fixing axle 9 is provided with a propeller 4。This propeller 4 is rotated by drive motor, thus further driving the rotation of filter interior liquid。In the present embodiment, the first filter screen group the 5, second filter screen group 6 and the 3rd drainage screen group it is disposed with from top to down above propeller 4, here first filter screen group the 5, second filter screen group 6 and the 3rd filter screen group 7 are provided with two-layer, its cross section of filter screen being positioned at lower floor is disposed as arrowhead form, arrow tip is downward, and lower screen is more thick the closer to tip place thickness。Such lower screen filter effect of drainage screen when the closer to center is more good, because the reason of liquid in rotation, so can at most by paracentral impurity, the setting that therefore thickness is relative is the thickest。Meanwhile, this filter screen is not such setting of level, increases the contact area between liquid and filter screen, is equivalent to expand filter area, thus reaching better filter effect。And in the present embodiment, the thickness of the lower screen center of the first filter screen group 5 is more than the thickness of the lower screen center of the second filter screen group 6, and the thickness of the lower screen center of the second filter screen group 6 is more than the thickness of the lower screen center of the 3rd filter screen group 7。Such setting, due to impurity from top to bottom, reduces successively, so also being reduced successively by the thickness of filter screen, more rationally, has saved cost。In the present embodiment, being provided with upper screen 8 in each filter screen group, this upper screen 8 is arranged on the top of lower screen, center alignment。And the area coverage of upper screen 8 is lower screen area coverage 1/4th。So can reasonably save screen material, in the central area that impurity is maximum, strengthen its filter effect by upper screen 8。

The above is preferred implementation of the present utility model, and to those skilled in the art without departing under the premise of this utility model principle, it is also possible to make some modification and improvement, these also should be regarded as the protection domain of utility model。
