The circuit of the automatic grinding device is shown in fig. 3, wherein QF is a circuit breaker, FR is a thermal relay, KM1 is an alternating current contactor, SQ is a travel switch controlled by an output signal of a feeding sensing probe, and SB is a button. When QF is connected, SB is pressed down, when the material reaches the lower limit of the set value, SQ is closed, KM1 is closed, the circuit is in a closed loop, and the grinding feeding gear pump starts to operate, namely the equipment starts to feed.

The discharging part is similar, the closing of the whole circuit is controlled by the height of the material in the funnel-shaped material receiving groove, and then the starting and stopping of the grinding discharging gear pump are controlled, so that the automatic feeding and discharging process of the automatic grinding device is completed.
The rotatable filter element is a net-shaped body.
The fixing frame is spaced from the filter element, and the fixing frame is arranged to prevent the filter element from shaking.
The scraping blade is used for hanging materials on the outer wall of the rotatable filter element in the rotating process.
The specified amount of the thinner and the tackifier are put into a storage tank A, after the addition is finished, a stirrer is started, and the rotating speed of the stirrer is gradually increased until the rotating speed is 50r/min; the tackifier is fully dispersed into the thinner under the action of the stirrer, and after the thickener is fully dispersed, the rotating speed of the stirrer is reduced, and the stirrer is closed; at the moment, opening an outlet valve below the storage tank A, putting materials into the kneader, and closing the outlet valve of the storage tank A; the powder is put into a storage tank B, after the powder is put into the storage tank B, an outlet valve of the storage tank B is opened, and a kneader is opened to start stirring the powder; after all the powder in the storage tank B enters the kneader, closing an outlet valve of the storage tank B; at this time, the material is added again in the tank A, B without affecting the operation of the lower kneader. The method can not only ensure uniform material dispersion and product quality, but also save time and improve the production efficiency of enterprises.
When the outlet valve of the storage tank is opened, the outlet valve of the storage tank A is opened first, and then the outlet valve of the storage tank B is opened; or the outlet valve of tank a and the outlet valve of tank B are alternately opened during the feeding, but the outlet valve of tank a is opened first at the beginning of the feeding. Therefore, the powder is prevented from being deposited at the bottom of the kneader, the powder is not easy to disperse in the thin material to cause unqualified product performance, and in addition, the long-term deposition of the powder can also cause damage in the kneader to influence the service life of the kneader.
The stirrer adopts a variable-frequency centrifugal propulsion stirrer, the diameter of the impeller is 0.2-0.5 times of the diameter of the storage tank A, the rotating speed of the stirrer is 100-500 r/min, and the peripheral speed of the end part of the impeller is 5-15 m/s. The impeller is like a shell-less axial flow pump, and the impeller rotating at high speed imparts axial and tangential motion to the liquid. The axial component speed of the liquid makes the liquid move downwards along the axial direction, and when flowing to the bottom of the kettle, the liquid is folded back along the wall of the kettle and returned back to the slurry inlet, so that the total fluid movement is formed, and the effect of mixing the liquid is achieved. The stirring mode can avoid the defect that the materials are deposited at the bottom of the storage tank and are unevenly mixed due to the fact that the storage tank is funnel-shaped. Therefore, the adoption of the push-type stirrer can fully mix the tackifier and the thinner, and the rotating speed of the stirrer can be randomly regulated according to the production requirement.

After a discharging button of the kneader is started, a feeding electromagnetic valve is started to open, and materials enter a funnel-shaped tank body through a three-way pipe by a feeding gear pump of a storage tank; after the materials in the kneader are discharged, the feeding electromagnetic valve is closed; after the grinding feeding is started, a discharging electromagnetic valve is opened, a discharging gear pump of a storage tank starts to rotate, and materials are conveyed to a grinding machine through a pipeline; when the liquid level of the colloid material in the funnel-shaped tank body is lowered to a set height, the infrared probe outputs signals, the vertical motor is started, the colloid on the wall is scraped, the colloid is concentrated at the bottom of the funnel-shaped tank body, and residual materials are prevented from remaining.
The grinding machine drives the roll shaft to rotate through the transmission device, and the strong shearing external force damages the structural stress among molecules in the raw material particles through the rapid friction reaction caused by the opposite asynchronous rotation of the middle roll and the rear roll, so that the high uniform mixing of various raw materials is achieved.
After the grinding machine is started, the quick and slow rollers are slowly adjusted to a certain position, a small amount of feeding of a grinding feeding gear pump is started, the distance between rollers is adjusted by adjusting the position of a hand wheel according to the required fineness, when the pasty substance is a colored material, the satisfactory rollers are adjusted, the depth of the surface color is consistent, and the normal feeding is resumed after the adjustment is finished; the grinding process of the ground material is mainly practiced by mutual extrusion and friction of a fast roller, a slow roller and a middle roller, and meanwhile, the fast roller plays a role in bringing out the ground material.
When the outlet at the upper end of the grinding feeding pipeline starts discharging, when the height of the material on the roller is smaller than the lower limit of the set value, the grinding feeding gear pump stops feeding, and when the height of the material on the roller is greater than the upper limit of the set value, the grinding feeding gear pump is restarted to start feeding; when the material in the funnel-shaped receiving groove is at a specified distance from the discharge sensing probe, the grinding discharge gear pump starts and stops to operate, so that overflow of the funnel-shaped receiving groove or idle running of the grinding discharge gear pump is avoided.
And a safety valve is arranged between the inlet of the grinding feeding gear pump and the other end of the discharging electromagnetic valve. The safety valve can avoid the material overflow caused by the abnormality of the feeding system due to unexpected conditions.

When the grinder works for a certain time, the materials between the rollers can suddenly appear uneven discharge color (generally, the middle discharge is thinner, and the two discharge ends are thicker), and the possible reason is that the grinder works for a long time and then the rollers are subjected to thermal expansion, so that cooling water is required to be introduced for adjustment, the rollers generate heat through surface friction, and the rollers can generate thermal expansion due to the influence of temperature.
The vertical shell is fixed with the upper cover through screws, and the filtering impurity remover and the filtering impurity removing motor are fixedly arranged on the frame through screws. The upper cover is fixed with the shell by screws, and is convenient to detach.
