Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It better understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Firstly, shown in first please referring to Fig.1 to Fig.3, a kind of brush holder support formula filter device, it includes: a cartridge filter 10 and one
Agitating unit 20, which has the upper cover 12 of a stack shell 11 and a sealing cover above the stack shell 11, in the stack shell 11
Empty and separation has not connected a first chamber 111 and a second chamber 112, and the first chamber 111 is by 11 bottom of stack shell
Portion sets one first discrepancy water pipe 113, which then sets a water inlet pipe by the bottom of the stack shell 11 and side respectively
114 and an outlet pipe 115, the first discrepancy water pipe 113 and the water inlet pipe 114 be equipped with switch unit 116,117, and should
First discrepancy water pipe 113 and water inlet pipe 114 connect outside in the cartridge filter 10 with a connection water pipe 118, and in connection water pipe 118
If a switch member 119, and one first filter septum 13 is equipped between first and second chamber 111,112, in the first chamber 111
And be higher than the outlet pipe 115 and set one second filter septum 14, and 14 centre of the second filter septum sets a limit jack-post 141,
And a bearing 142 is set inside the limit jack-post 141, which sets one second discrepancy water pipe 121, and is lower than in inside
The second discrepancy water pipe 121 sets a third filter septum 15, which there is an actuator 21 to be installed on the cartridge filter
At 10 bottom centers, and one shaft 22 of connection is driven, wherein the actuator 21 is a drive motor, and passes through 211 groups of a bracket
11 bottom of stack shell set on the cartridge filter 10 is connect with the shaft 22, which also can be proficiency turning handle (figure does not indicate),
11 bottom of stack shell for being mounted on the cartridge filter 10 is connect with the shaft 22, and above-mentioned shaft 22 is protruded into the first chamber 111 and worn
13,14,15 centre of the first, second and third filter septum is crossed, and sets a stirring parts 23, the stirring parts in 22 upper half of shaft
23 set a first crossbar 231 between second and third filter septum 14,15, and one is set above the third filter septum 15
Two cross bars 232, the first crossbar 231 is past to have multiple parallel longitudinal stirring rods 233, and these 223 bottoms of stirring rod
End is equipped with the whole sand plate 234 being staggered in inclined plate shape in the first crossbar 232 apart from about 5 centimetres of second filter septum 14,
And the first crossbar 231 and the second crossbar 232 are equipped with hairbrush 235 towards the third filter septum 15.
The use of its structure, then please refer to shown in Fig. 3, Fig. 4, first and second chamber 111,112 is in first and second filtering
Partition 13,14 is equipped with filter element, then is equipped with filtering sand material, the filter sand by 14,15 heaps of second and third filter septum
Material does not limit to thickness accumulation mode, can be by slightly to thin or carefully to slightly sequentially accumulating, and actual filtration is in use, this first enters and leaves
The switch unit 116,117 of water pipe 113 and water inlet pipe 114 is open state, and the switch member 119 of the connection water pipe 118 is then
Be in off state, the water source to be filtered by second enter and leave water pipe 121 import first chamber 111 in, by the third filtering every
Filter element between the filtering sand material accumulated between plate 15 and the first and second filter septum 13,14 carries out primary filtration, then by the
One enters and leaves water pipe 113 for the water flow export by the filtering of first portion and imports in second chamber 112 along water inlet pipe 114, and via
The filter element of second chamber 112 carries out secondary filter, is finally discharged by the outlet pipe 115 of side, achievees the purpose that filtering.
Furthermore when the cartridge filter 10 is after filtering use after a period of time, because filter element and filtering sand material can adsorb
Impurities in water, microorganism and parasitic ovum, and influence the effect of water filtration, it is necessary to back washing operation is carried out, to keep filter material
Filter effect then please referred to shown in Fig. 5, Fig. 6 when carrying out the back washing operation of first chamber 111, first by the water inlet pipe 114
Switch unit 117 close, while opening this and first entering and leaving switch unit 116 of water pipe 113 and opening for the connection water pipe 118
Part 119 is closed, and connects clean water flow via connection water pipe 118 and enters and leaves water pipe 113 along first and import in first chamber 111,
It carries out the filter element in first chamber 111 and filters the cleaning of sand material, and by the enabling of actuator 21, making should be positioned at the
23 Stirring of stirring parts of one chamber, 111 upper half, one stirs the filtering sand material between second and third filter septum 14,15,
It is carried over the dirty of attachment, while the leveling that can be also filtered sand material using whole sand plate 234 is acted, and filter sand is reached
The holding of the average thickness of material, it is ensured that the effect and efficiency of filtering, two also pass through the hairbrush 235 of the first and second cross bar 231,232
The scrub cleaning for carrying out third filter septum 15, the green alga on third filter septum 15 is removed, finally will be dirty further along water flow
Dirt enters and leaves water pipe discharge from second, completes the back washing cleaning of first chamber 111 whereby, while retaining the second chamber 112 not
Clean conditions, and the culture ecological in former pond must be retained in second chamber 112, when being filtered operation next time,
The culture ecological retained in the second chamber 112 can also be imported in pond, it is too big to avoid filtering water vicissitude, and have
Influence the survival doubt of biological cultivation.
The filtering of second chamber 112 after a period of use, and must carry out the clean operation of back washing, back washing
When, it is continuous to please refer to shown in Fig. 7, it opens the switch unit 117 of the water inlet pipe 114 and is connected to the switch member 119 of water pipe 118, together
When close first switch unit 116 for entering and leaving water pipe 113, whereby by clean water source from connection water pipe 118 and water inlet pipe 114
Second chamber 112 is imported, and then dirty accompanying by cleaning second chamber 112 and self-filtering unit, finally again by being discharged
Pipe 115 is discharged, and reaches the clean purpose of back washing of the second chamber 112.
By means of the structure of above-mentioned specific embodiment, following benefits can be obtained: (one) agitating unit 20 is set by stirring parts 23
There are two hairbrush 235, which is configured at the upper and lower side of third filter septum 15, can pass through this two maos when back washing operation
Brush 235 scrubs the third filter septum 15, and the green alga on the third filter septum 15 is scrubbed removal really, promotes filtering effect
Fruit.
(2) separating in the cartridge filter 10 has first chamber 111 and second chamber 112, not only with two different spaces
Filter facilitates the promotion of filter effect, on the other hand the first and second chamber 111 of the cartridge filter 10,112 back washings out of the ordinary
The water of back washing consumption is greatly reduced in cleaning, and when back washing operation can the only single cleaning for carrying out the first chamber 111, and protect
The 112 remaining culture ecological of institute of second chamber is stayed, when being filtered operation in favor of next time, filtering water can be avoided to become really
Change upheaval is too big, and then keeps the survival rate of pond biological cultivation.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.Those skilled in the art's made equivalent substitute or transformation on the basis of the present invention, in the present invention
Protection scope within.Protection scope of the present invention is subject to claims.
