The settling tank of the hydroresorcinol solid-liquid separation of non air exit hole
Technical field
The present invention relates to a kind of settling tank, the 1 of a kind of non air exit hole, the settling tank of hydroresorcinol solid-liquid separation.
Background technology
Settling tank separation liquid to be utilized and precipitate, such as 1,3 cyclohexanediones are to separate feed liquid and metallic catalyst in producing, and precipitate is because proportion is distributed in tank base region relatively greatly after precipitation.General settling tank be bottom valve is opened after first precipitate is released thing to be precipitated put clean after reconvert discharge the supernatant.This method has the disadvantage that precipitate does not has obvious boundary with the conversion of the supernatant, the precipitate being positioned at blow-off valve doorway vertical direction is taken the lead in flowing out by gravity and flow action, then the clear liquid on upper strata just starts to drive the precipitate of discharge gate cataclysm to mix outflow therewith, is then exhausted from until precipitate changes clear liquid after substantially emptying.And the precipitate discharged is mixed with a considerable amount of clear liquid, it is necessary to the precipitate discharged is carried out after-treatment or ignore and slatterns.
Summary of the invention
The problem that the present invention exists according to prior art, it is proposed that the 1 of a kind of non air exit hole, the settling tank of hydroresorcinol solid-liquid separation, solve existing feed liquid settling tank part clear liquid and mix with precipitate, need to carry out after-treatment or the problem of feed liquid waste.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that

nullThe present invention uses flow transducer、Infrared range-measurement system、Servomotor、Displacement transducer respectively with the design of PLC,After mixed liquor enters settling tank,Precipitation through certain time,After solid-liquid layering,The clear liquid mozzle outer tube peak distance to solid-liquid layering face measured by infrared range-measurement system,Then signal is sent,PLC receives signal,Slope and inner tube altimeter according to inclined-plane, inner tube upper end calculate the angle that inner tube should rotate,Control servomotor to rotate for the first time,The respective angles turning to calculate 3/4ths time,Displacement transducer sends signal,PLC receives signal,And control servomotor to stop operating,The clear liquid allowing top flows out tank body,When flowing out without clear liquid in discharging opening,Flow transducer sends signal,PLC receives signal,Control servomotor second time to rotate,During the angle of be now rotated further by calculating 1/4th of respective angles,Displacement transducer sends signal,PLC receives signal,And control servomotor to stop operating,Reach automatic、The purpose accurately rotated.The design of this scheme, rotary course rotates at twice, avoid once rotate to solid-liquid layering face time, substantial amounts of clear liquid flows out tank body by strip through hole, more solid is driven to enter in clear liquid, make to separate the most thorough, twice it is avoided that such problem, substantial amounts of clear liquid is made to flow out tank body for the first time, second time is rotated again to solid-liquid layering face, and now the clear liquid in tank body is the most less, and the flow velocity flowing out tank body is more slow, greatly reduce solid and enter the quantity of clear liquid so that separate more thorough.
When clear liquid mozzle inner tube rotates, clear liquid in tank body is not blocked outside part pouring vessel by the strip through hole on outer tube, now the strip through hole on outer tube is not blocked and partly tank body is connected with atmospheric pressure, serve the effect of a steam vent, in making tank body, air pressure balance outer with tank body, eliminates the steam vent of general tank design.
Further, angle disk includes that angle scale and cursor, described cursor are arranged on above angle scale, and described cursor and servo motor output shaft are in transmission connection, and described cursor is in transmission connection with rotating handles.
Further, angle scale is semi-circular shape.
Further, clear liquid mozzle top is equal with tank body overhead height.
Compared with prior art, the 1 of non air exit hole of the present invention, the settling tank of hydroresorcinol solid-liquid separation, use inner tube outer tube as clear liquid mozzle, realizing clear liquid by rotation to be discharged to from top to bottom outside tank, clear liquid and precipitate only have few mixing, it is not necessary to carry out after-treatment, decreasing the waste of material, production efficiency is significantly improved.

All parts for the present embodiment explains:
1) angle disk includes that angle scale 11 and cursor 18, described cursor 18 are arranged on above angle scale 11, and described cursor 18 and servomotor 10 output shaft are in transmission connection, and described cursor is in transmission connection with rotating handles.
2) angle scale 11 is semi-circular shape.
3) clear liquid mozzle top is equal with tank body 1 overhead height.
nullOperation principle: after mixed liquor enters settling tank,Precipitation through certain time,After solid-liquid layering,The clear liquid mozzle outer tube peak distance to solid-liquid layering face measured by infrared range-measurement system,Then signal is sent,PLC receives signal,Slope and inner tube altimeter according to inclined-plane, inner tube upper end calculate the angle that inner tube should rotate,Control servomotor to rotate for the first time,The respective angles turning to calculate 3/4ths time,Displacement transducer sends signal,PLC receives signal,And control servomotor to stop operating,The clear liquid allowing top flows out tank body,When flowing out without clear liquid in discharging opening,Flow transducer sends signal,PLC receives signal,Control servomotor second time to rotate,During the angle of be now rotated further by calculating 1/4th of respective angles,Displacement transducer sends signal,PLC receives signal,And control servomotor to stop operating,Reach automatic、The purpose accurately rotated.The design of this scheme, rotary course rotates at twice, avoid once rotate to solid-liquid layering face time, substantial amounts of clear liquid flows out tank body by strip through hole, more solid is driven to enter in clear liquid, make to separate the most thorough, twice it is avoided that such problem, substantial amounts of clear liquid is made to flow out tank body for the first time, second time is rotated again to solid-liquid layering face, and now the clear liquid in tank body is the most less, and the flow velocity flowing out tank body is more slow, greatly reduce solid and enter the quantity of clear liquid so that separate more thorough.
When clear liquid mozzle inner tube rotates, clear liquid in tank body is not blocked outside part pouring vessel by the strip through hole on outer tube, now the strip through hole on outer tube is not blocked and partly tank body is connected with atmospheric pressure, serve the effect of a steam vent, in making tank body, air pressure balance outer with tank body, eliminates the steam vent of general tank design.
These are only the preferred embodiment of the present invention, it is noted that for the ordinary skill in the art, without departing under the principle premise of the present invention, it is also possible to make various deformation and improvement, this also should be considered as protection scope of the present invention.
