Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1, the deposition tower 1 is connected with an injection machine 2, a discharge port of the injection machine 2 is connected with a transmission pipeline 3, at least one press feeding valve 4 is arranged on the transmission pipeline 3, the press feeding valve 4 is connected with a press barrel 5, the press barrel 5 is connected with a press material pumping pump 6, and materials in the press barrel 5 are conveyed to a mold cavity of a press through the press material pumping pump 6.
The production flow of the system is as follows: the slurry for producing ferrite products is precipitated by a precipitation tower 1, after the water content reaches the use requirement, the slurry enters a transmission pipeline 3 from the precipitation tower 1 through a material injection machine 2, then the slurry is conveyed to a press charging bucket 5 through a press feeding valve 4, the press charging bucket 5 is switched to other press charging buckets after being full of materials, an automatic circulation flow is started, and the materials of the press charging bucket 5 are pressed into green bodies after being conveyed to a die cavity of a press through a press material pumping pump. Generally, a plurality of settling towers correspond to a plurality of presses in production.
In this embodiment, the transmission pipeline 3 is provided with a plurality of press feed valves 4 corresponding to the number of presses one to one, each press feed valve 4 is connected with one press bucket 5, and the press feed valves 4 are used for controlling the amount of slurry entering the press buckets 5, so as to prevent the slurry from overflowing the press buckets 5.
Because the specific gravity difference between the ferrite molding slurry and the material water is large, the material water is easy to separate, and the material is fast settled, in the embodiment, a stirrer 7 is arranged in the settling tower 1. The stirrer 7 can fully stir the material slurry in the settling tower 1, so that the slurry and the material water can be fully mixed.
In this embodiment, a pressure relief pipe 8 is arranged on the transmission pipeline 3, one end of the pressure relief pipe 8 is connected with the transmission pipeline 3, the other end of the pressure relief pipe 8 is connected with the settling tower 1, and a pressure relief material return valve 9 is arranged at the joint of the pressure relief pipe 8 and the settling tower 1. Because the ferrite molding slurry is high in concentration and poor in fluidity, if the pumping system stops feeding, the pressure relief material returning valve 9 is not opened or the feeding valve 4 of the press is closed after 1-5 seconds of delay, and the residual pressure in the pipeline is basically equal to the pumping pressure, so that pipe explosion or valve clamping can be caused.
The outlet of the injection machine 2 is connected to each press barrel 5 by a pipeline, and is connected with the feed inlet of the press barrel 5 by each press feed valve 4 which is controlled by the control system of the press.
During operation, at the same time, in order to ensure that only one press sends out a signal and only one press charging bucket opens a press charging valve, a sequencing control method must be designed.

first full charge of press bucket 5: opening a feeding valve 4 of the press and a feeding valve 10 of the material injection machine, closing a pressure relief material returning valve 9, starting the material injection machine 2, observing the fullness of the material barrel 5 of the press, closing the feeding valve 4 of the press and the material injection machine 2, and recording the discharging time (set as A). The lowest material storage amount of the press material barrel is generally one fourth of that of the press material barrel, and the material supplementing time length of the press material barrel is B (B = 3A/4);
starting the press, starting automatic pressing, recording the pressing modulus, and recording the pressing modulus as C when only one fourth of the residual material in the material barrel 5 of the press is observed;
setting the obtained parameters of the feeding time B and the modulus C into a press control system, and sending a discharging signal by the press control system: opening a feeding valve 4 of the press, closing a pressure relief material returning valve 9, starting a material injection machine 2 (a feeding valve 10 of the material injection machine is opened at ordinary times) to inject materials into a material barrel 5 of the press, starting timing, and recording the pressing modulus again; when the time is B, the material control system of the press stops discharging signals, the material injection machine 2 stops, the pressure relief material return valve 9 is opened, the time is delayed for 1 second, the material inlet valve 10 of the press is closed, and the residual pressure in the material pipe is fully released;
continuing pressing until the recorded pressing modulus is C, and sending a discharging signal by the press material control system: opening a feeding valve 4 of the press, closing a pressure relief material returning valve 9, starting a material injecting machine 2 to inject materials into a material barrel 5 of the press, starting timing, and recording the pressing modulus again;
when the time reaches 2B, the material control system of the press stops discharging signals, the material injection machine 2 stops, the pressure relief material return valve 9 is opened, the time is delayed for 1 second, the material inlet valve 10 of the press is closed, and the residual pressure in the material discharge pipe is fully released;
