Utility model works process：Kitchen sewage is added to filter chamber 10 from sewage inlet 11, pacifies by filter chamber 10
The screen pack 12 of dress removes the kitchen garbage such as dish leaf of bulk, then enters water oil separation by the passage of the bottom of filter chamber 10
Room 20；Oil slick, water, sludge objectionable intermingling in kitchen sewage, it is layered because density is different, the lighter oil slick of density rises to
First oil slick passage 21, and floating oil collecting room 30 is entered from the first oil slick outlet 211, then pass through the discharge of the second oil slick outlet 31
To specified location, the heavier sludge of density drops to the first sludge passage 22, and enters sludge from the first sludge outlet 221 and receive
Collect room 40, then specified location is emitted into by the second sludge outlet 41, the water layer of kitchen sewage is at the middle part of water oil separation chamber 20
Position is layered, and at this moment has two kinds of situations, and the first situation is that the horizontal plane of the water layer after separation is less than the first purification channel, now
It is oil slick in first purification channel, because the density of the first ball float 251 is more than the density of oil slick, ball float valve module 25 is not turned on,
And then stop oil slick by the way that second case is that the horizontal plane of the water layer after separation is higher than the first purification channel, and now first is net
It is water to change in passage, and because the density of the first ball float 251 is less than the density of water, ball float valve module 25 turns on, and water is net by first
Change passage, ball float valve module 25, the second purification channel to enter the first purified water collecting chamber 50, and pass through the row of the first purge outlet 51
Put to given place.
The utility model is hollow-core construction body, in the inner chamber of hollow-core construction body set filter chamber 10, water oil separation chamber 20,
Floating oil collecting room 30, sludge collecting chamber 40, the first purified water collecting chamber 50, water oil separation chamber 20 are a middle part big, upper and lower two
Small cavity, can quickly realize layering；The top and bottom of water oil separation chamber 20 are connected with hollow-core construction body, by sky
The inner chamber of core structure body is divided into positioned at the filter chamber 10 in the upper left corner, positioned at the floating oil collecting room 30 in the upper right corner, positioned at the lower left corner
Sludge collecting chamber 40, the first purified water collecting chamber 50 positioned at the lower section of floating oil collecting room 30, it is compact-sized, simple；Water oil
From the ball float valve module 25 set in room 20, the ball float valve module 25 includes the first ball float 251, valve body 252, to pass through first
Ball float 251 and valve body 252 cover or separate control the connection of the first purified water passage 23 and the second purified water passage 24 or
Do not connect；The kitchen sewage separator separating effect such as oil interceptor in compared with prior art is more preferable；The utility model device
Small volume, therefore it is adapted to family to use, solve the processing of family's kitchen sewage, saved water resource.
Referring to Fig. 1 and Fig. 2, further, the side wall also in the second purified water passage 24 close to the first purified water collecting chamber 50
It is upper set allow water by and do not allow the pellicle 241 that passes through of oil.
For this programme, pellicle 241 is that one kind can allow hydrone by, the intransitable material of oil slick, as above
Two kinds of situations, the first situation is that the horizontal plane of the water layer after separation be less than the first purification channel, and second case is to separate
The horizontal plane of water layer afterwards is higher than the first purification channel, the first ball float when the first situation converts to second case be present
251 a part in oil slick, and a part in water when, the first ball float 251 be just buoyancy be more than gravity and turn on
Situation, at this moment a small amount of oil slick can enter the first purified water collecting chamber 50 by ball float valve module 25, when addition pellicle 241
Afterwards, even a small amount of oil slick in this part can also be effectively prevented from entering the first purified water collecting chamber 50, it ensure that water
Separating effect of the oil separation chamber 20 to water.
Referring to Fig. 1 and Fig. 2, further, family expenses kitchen sewage purifier is additionally provided with the second purified water collecting chamber 60, the
Two purified water collecting chambers 60 are located at the lower section of the first purified water collecting chamber 50, and are purified in the first purified water collecting chamber 50, second
Activated carbon filter layer 61 is provided between water collecting chamber 60, to flow into the second purified water collecting chamber 60 to the first purified water collecting chamber 50
Water filtered, the bottom of the second purified water collecting chamber 60 is provided with the second purge outlet 62, and on the second purge outlet 62
4th valve 63 is installed.
Activated carbon filter layer 61, further mistake are set between the first purified water collecting chamber 50 and the second purified water collecting chamber 60
Filter the effect of the impurity, also taste removal in the water isolated；Can be the first purified water collecting chamber 50 by the first purge outlet 51
Oiling agent is added, with the impurity adhered on scavenging capacity charcoal filter layer 61, the filter capacity of activity recovery charcoal filter layer 61.
Referring to Fig. 1 and Fig. 2, further, the second ball float 26, above-mentioned first oil slick passage are provided with the top of water oil separation chamber 20
21 be cylindrical channel, and the diameter of the second ball float 26 is more than the diameter of the first oil slick passage 21, the density of the second ball float 26 between
Between water and the density of oil slick, with covering or separating to control by the second ball float 26 and the porch of the first oil slick passage 21
First oil slick passage 21 is connected with the inside of water oil separation chamber 20 or not connected；When the gravity of the second ball float 26 is more than buoyancy,
Two ball floats 26 separate with the porch of the first oil slick passage 21, so that oil slick can enter floating oil collecting room by first passage that swims
30；When the gravity of the second ball float 26 is less than buoyancy, the porch of the second ball float 26 and the first oil slick passage 21 covers, to prevent water
Water in oil separation chamber 20 enters floating oil collecting room 30 by first passage that swims.
The density of the oil slick of the superiors is less than the density of the second ball float 26, the second ball float 26 and first in water oil separation chamber 20
Oil slick passage 21 separates, and at this moment the first oil slick passage 21 turns on, and oil slick flows into floating oil collecting room 30 from the first oil slick passage 21, when
After the oil slick of the superiors drains in water oil separation chamber 20, now the environment where the second ball float 26 is changed into water layer, the second ball float 26
Density be less than the density of water, the second ball float 26 covered with the first oil slick passage 21, and at this moment the first oil slick passage 21 is not turned on, and is hindered
Sealing flows into floating oil collecting room 30 from the first oil slick passage 21, and the effect of this programme is to ensure water oil separation chamber 20 to oil slick
Separating effect.
Module or unit in the utility model embodiment device can be merged, divide and deleted according to being actually needed
Subtract.
Above disclosed is only the utility model preferred embodiment, can not limit the utility model with this certainly
Interest field, one of ordinary skill in the art will appreciate that realize all or part of flow of above-described embodiment, and according to this reality
The equivalent variations made with new claim, still fall within the scope that utility model is covered.
