Specific embodiment
As shown in Figure 1-3, a kind of ceramic body filling forming method, comprising:
One, slip casting: inlet pipe 120 is opened, mud is injected into the slip casting bucket 110 being communicated with the atmosphere, until slip casting bucket 110
When interior mud rises to the first liquid level L1, inlet pipe is closed, and carry out lower slurry.
Two, lower slurry: opening pulp feeding pipe 130, by mud injection point slurry pipe 140, until the mud in slip casting bucket 110 drops to
When the second liquid level L2, pulp feeding pipe 130 is closed, returns to slip casting step.
Three, mud injection molding prepares:
(1) it during lower slurry, when the liquid level in the horizontal level device 150 on point slurry pipe 140 reaches default liquid level, closes
Pulp feeding pipe is closed, is executed step (2)；
Wherein, liquid level is preset to flush with the inlet of mold 190.
(2) after the liquid level of horizontal level device 150 and multiple Grouting Pipes 160 on point slurry pipe 140 maintains an equal level, lower slurry is opened
Pipe 130 continues lower slurry, and return step (1), until the liquid level of horizontal level device 150 and Grouting Pipe 160 maintains an equal level above-mentioned pre-
If when liquid level, carrying out mud casting.
Four, mud casting: closing horizontal level device 150, opens pulp feeding pipe 130, and the mud in slip casting bucket 110 is infused
Enter multiple molds 190, when the liquid level in mold 190 reaches injection molding liquid level, carries out the molding of ceramic body.
Wherein, injection molding liquid level is located at the top outside mold and lower than the second liquid level L2.
Five, after ceramic body molding, mud is withdrawn by closed recovery channel 180 by original by diaphragm pump 170
Expect to prevent impurity in slurry tank and be mixed into mud, cause bad, diaphragm pump 170 is controlled by PLC controller 198, avoids occurring to overflow
Slurry.
Traditional approach is open type overfall, is easily mixed into impurity, pollutes mud, and be to manually control when plasma discharge, it may occur that is returned
Slurry bucket, which is overflow, starches.
The present invention controls the liquid level in slip casting bucket 110 by the first liquid level L1 and the second liquid level L2, can in slip casting
To keep relative constant grouting pressure, and pressure is smaller, prevents before die gap spillage, mud injection molding through horizontal liquid
Position device 150 keeps sustained height (default liquid level) when ensuring that mud enters mold, it is ensured that air in pipeline all emptying and
Reduce the thickness difference between green body.The position of first liquid level L1 is higher than the second liquid level L2.
Wherein, slip casting bucket 110 connects inlet pipe 120, and one end through the connection point slurry pipe 140 of pulp feeding pipe 130, point slurry pipe
140 are sequentially connected horizontal level device 150 and multiple Grouting Pipes 160 from back to front, and the other end of this point slurry pipe 160 passes through diaphragm
The closed recovery channel 180 of 170 connection of pump, multiple Grouting Pipes 160 are separately connected a mold 190, and multiple molds 190 are along a point slurry
140 direction of pipe, which is successively spaced, to be set on a bracket 199, and the top of each mold 190 has the tube body of insertion mold, to make to infuse
Mould liquid level is located above mold.
The first liquid level sensor 111 and second for detecting liquid level is respectively provided in slip casting bucket 110 and mold 190
The first solenoid valve 121 and second solenoid valve 131 are respectively equipped on liquid level sensor 191, inlet pipe 120 and pulp feeding pipe 130,
First liquid level sensor 111, the second liquid level sensor 191, the first solenoid valve 121, second solenoid valve 131, horizontal level device 150
And diaphragm pump 170 is connect with PLC controller 198.
PLC controller 198 detects the liquid level in slip casting bucket 110 by the first liquid level sensor 111, and PLC controller 198 is logical
The liquid level in the second liquid level sensor 191 detection mold 190 is crossed, PLC controller 198 plays on or off by the first solenoid valve 121
Inlet pipe 120 is closed, PLC controller 198 opens or closes pulp feeding pipe 130 by second solenoid valve 131.
It should be pointed out that equally having solenoid valve in horizontal level device 150, opened to control it by PLC controller 198
It closes.
It is connect preferably, Grouting Pipe 160 is oblique with a point lower side for slurry pipe 140, the angle a with horizontal plane is in 10-
15 ° of angles, bubble are not easy to enter in mold 190 from a point slurry pipe 140, avoid generating bubble on ceramic body.
Wherein, slip casting bucket 110 is transparent drum, and convenient for finding the scarce slurry of mud in time, the situation of bubble in mud is reduced not
It is good to happen.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Invention, and be not used as limitation of the invention, as long as in spirit of the invention, to embodiment described above
Variation, modification will all fall within the scope of claims of the present invention.
