Formaldehyde scavenger filter device
Technical field
The utility model is related to the use technical field of tools of formaldehyde scavenger, specifically, being related to a kind of formaldehyde removing
Agent filter device.
Background technology
Zein formaldehyde scavenger preparation process includes step:Zein raw material addition water and acid protease is taken to add
Zein suspension is made in heat enzymolysis, the zein suspension after then aoxidizing to aoxidize, and the zein after oxidation is outstanding
Supernatant liquid is added a certain proportion of decolorising agent and is heated to 80~95 DEG C of decolorations, and the corn suspension after decoloration adds the originals such as citric acid again
Zein formaldehyde scavenger, then filling manufacture is made in material.
But can sometimes have dregs in the corn suspension after decolourizing, make the clarity of zein formaldehyde scavenger
It is low, influence the quality of zein formaldehyde scavenger.
Utility model content
Technical problem to be solved in the utility model is:It is clear to provide a kind of formaldehyde that can remove dregs in corn suspension
Except agent filter device.
In order to solve the above technical problems, the technical solution of the utility model is:
Formaldehyde scavenger filter device, including controller and filter residue container, the filter residue container include set on left side into
Sap cavity and right side go out sap cavity, the admission chamber and go out between sap cavity to be vertically provided with filter screen, connection on the upside of the admission chamber
Have an input duct, the input duct is equipped with check valve, it is described go out sap cavity be connected with outlet tube, the outlet tube is equipped with electricity
Magnet valve, it is described go out sap cavity be connected with the blowback tracheae being arranged towards the filter screen, the blowback tracheae is equipped with solenoid valve;
The left end of the admission chamber is equipped with first hydraulic cylinder, the cavity wall of the piston of the first hydraulic cylinder and the admission chamber
It is slidingly sealed cooperation, second hydraulic cylinder, the piston of the second hydraulic cylinder and the filter screen are equipped on the upside of the admission chamber
Left side wall sliding contact coordinates, and admission chamber downside at the filter screen is connected with dregs outlet pipe, the dregs outlet pipe
Equipped with solenoid valve, baffle, the top of the baffle and the feed liquor are vertically equipped in the admission chamber at the dregs outlet pipe
There are inlets between the roof of chamber;
The first hydraulic cylinder, the second hydraulic cylinder, the solenoid valve and the check valve are electrically connected described
Controller.
Preferably, the input duct is set on the left of the baffle, and at the baffle.
Preferably, it is described go out sap cavity longitudinal section be triangle, the blowback tracheae is obliquely installed towards the filter screen
It is described go out sap cavity upside cavity wall on.
Preferably, the controller is PLC.
By adopting the above-described technical solution, the utility model has the beneficial effects that:
Input duct is connected decoloring reaction kettle, the corn after decoloration by the formaldehyde scavenger filter device of the utility model
Suspension enters the admission chamber of the device, the check valve being then shut off in input duct, first hydraulic cylinder action, first hydraulic cylinder
Piston promote, overstock admission chamber in corn suspension by filter screen enter sap cavity output.After having filtered, blowback is utilized
Tracheae is blown towards filter screen, can prevent filter screen from blocking, and improves filter efficiency, and the dregs accumulated at filter screen are second
The output of dregs outlet pipe is promoted under the action of hydraulic cylinder.It is outstanding can to remove corn for the formaldehyde scavenger filter device of the utility model
Dregs in supernatant liquid improve the quality of formaldehyde scavenger, and can remove accumulation dregs online in the case that non-stop-machine, improve
Production efficiency.

Specific implementation mode
Referring to Figures 1 and 2, the formaldehyde scavenger filter device of the present embodiment, including controller 20 and filter residue container 1, filter
Slag container 1 includes going out sap cavity 12 set on the admission chamber 11 in left side and right side, admission chamber 11 and is gone out vertically arranged between sap cavity 12
There are filter screen 13,11 upside of admission chamber to be connected with input duct 2, input duct 2 is equipped with check valve 3, goes out sap cavity 12 and be connected with
Outlet tube 10, go out sap cavity 12 and be connected with the blowback tracheae 9 being arranged towards filter screen.
The left end of admission chamber 11 is equipped with first hydraulic cylinder 4, and the piston 41 of first hydraulic cylinder is slided with the cavity wall of admission chamber 11
Sealing cooperation, 11 upside of admission chamber are equipped with second hydraulic cylinder 5, and the piston 51 of second hydraulic cylinder is slided with the left side wall of filter screen 13
Be engaged, the downside at filter screen 13 of admission chamber 11 is connected with dregs outlet pipe 7, on outlet tube 10, on blowback tracheae 9 and
Solenoid valve 8 is respectively equipped in dregs outlet pipe 7.In admission chamber 11 at dregs outlet pipe 7 vertically be equipped with baffle 6, the top of baffle 6 with into
There are inlets 30 between the roof of sap cavity 11.
First hydraulic cylinder 4, second hydraulic cylinder 5, solenoid valve 8 and check valve 3 are electrically connected controller 20.
Input duct 2 is set to the left side of baffle 6, and at baffle 6, such design enable 2 feed liquor of input duct when
Impact force is formed, prevents dregs from being accumulated in 6 left bottom angle of baffle.
The longitudinal section for going out sap cavity 12 is triangle, and blowback tracheae 9 is inclined at out the upper of sap cavity 12 towards filter screen 13
On side chamber wall.
Controller 20 is PLC.PLC programmable controller is product on sale on the market, realizes that logic control is using PLC
Its intrinsic function, the innovation being not belonging on software.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
