The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in figure 1, the invention provides a gel ball normal temperature aging device, which comprises a feeding pipe 2, a self-circulation pipeline 3, a tank body 1 and a filter screen 4 arranged in the tank body 1, wherein the tank body 1 is divided into an upper cavity and a lower cavity by the filter screen 4, and the aperture of the filter screen 4 is smaller than the diameter of a gel ball; the feeding pipe 2 is inserted on the tank body 1, the inlet of the feeding pipe 2 extends out of the tank body 1, the outlet extends to the lower part of the filter screen 4, and the feeding pipe 2 is provided with a feeding valve; the tank body 1 is provided with a liquid inlet 1-1, a liquid outlet 1-2, a self-circulation outlet 1-3, a self-circulation inlet 1-4, a constant volume overflow port 1-5 and a discharge port 1-6 which can be opened and closed, the discharge port 1-6 is arranged at the bottom of the tank body 1, the liquid outlet 1-2 is positioned above the filter screen 4, and the liquid outlet 1-2 is provided with a liquid outlet pump 5; the constant volume overflow ports 1-5, the self-circulation outlets 1-3 and the self-circulation inlets 1-4 are all positioned below the filter screen 4, the self-circulation outlets 1-3 are communicated with the self-circulation inlets 1-4 through self-circulation pipelines 3, and self-circulation pumps 6 are arranged on the self-circulation pipelines 3.
When in use: firstly, a feeding pipe 2 and a liquid outlet pump 5 of the device are respectively communicated with an outlet and an inlet of a dispersion column system, and meanwhile, discharge ports 1-6 are communicated with subsequent equipment; then, injecting ammonia water into the tank body 1 through the liquid inlet 1-1 until the tank body 1 is filled with the ammonia water;
then, the liquid inlet 1-1 is closed, and the feeding valve, the liquid outlet 1-2 and the liquid outlet pump 5 are opened at the same time. From this, under the suction effect of liquid pump 5, the aqueous ammonia in jar body 1 just constantly flows into dispersion column system, and meanwhile, the gel ball that dispersion column system produced also can flow into jar body 1 through inlet pipe 2 along with the aqueous ammonia in the dispersion column system together, that is to say, the gel ball that dispersion column system produced constantly gets into jar body 1 simultaneously, and the aqueous ammonia also constantly circulates between dispersion column system and jar body 1. In addition, because the outlet of the feeding pipe 2 is positioned below the filter screen 4 and the liquid outlet 1-2 is positioned above the filter screen 4, when the ammonia water circulates between the dispersion column system and the tank body 1, the gel balls in the tank body 1 are always stored in the tank body 1 and cannot flow into the dispersion column system along with the ammonia water;
next, the self-circulation outlets 1-3, the self-circulation inlets 1-4 and the self-circulation pump 6 are turned on. Because the outlet of the feeding pipe 2 is positioned below the filter screen 4, and the aperture of the filter screen 4 is smaller than the diameter of the gel ball, the gel balls output by the dispersion column system are all positioned in the lower cavity of the tank body 1, so that when the self-circulation outlet 1-3, the self-circulation inlet 1-4 and the self-circulation pump 6 are opened, namely the ammonia water in the tank body 1 starts to self-circulate, the gel balls in the tank body 1 can circularly move in the lower cavity under the driving of the ammonia water, and normal-temperature aging is started;
then, after the dispersion column system finishes the dispersion process, namely after all gel balls generated by the dispersion column system fall into the tank body 1, opening the constant volume overflow port 1-5 until the liquid level of the ammonia water in the tank body 1 is positioned below the filter screen 4;
and finally, after the normal-temperature aging process is finished, closing the self-circulation outlet 1-3, the self-circulation pump 6 and the self-circulation inlet 1-4, and opening the constant-volume overflow port 1-5 again until the liquid level of the ammonia water in the tank body 1 is positioned below the constant-volume overflow port 1-5, opening the discharge port 1-6, and enabling the gel balls in the tank body 1 to flow into subsequent equipment along with the residual ammonia water. Therefore, the constant volume overflow ports 1-5 can be used for constant volume of the ammonia water when the gel balls are discharged.
By last, this device simple structure, simple operation, during the use, through with inlet pipe 2 and liquid outlet 1-2 respectively with dispersion column system's export and import intercommunication, just can form the circulation circuit of aqueous ammonia between jar body 1 and dispersion column system to just also need not to set up the aqueous ammonia liquid storage pot for dispersion column system specially. And, because the export and the liquid outlet 1-2 of the inlet pipe 2 of jar body 1 are located the upper and lower both sides of filter screen 4 respectively, therefore aqueous ammonia when circulating between disperse column system and jar body 1, the gel ball in jar body 1 is stored all the time and is carried out the normal atmospheric temperature ageing in jar body 1 to just also avoided the gel ball to transport along with the aqueous ammonia and cause and take place to warp, damage even. In addition, the ammonia water in the tank body 1 is driven to flow in a self-circulation mode by the self-circulation pump 6, and the gel balls in the tank body 1 can be driven to move in a circulation mode, so that deformation and uneven reaction caused by standing and stacking of the gel balls during normal-temperature aging can be avoided, the sphericity of the gel balls can be improved, cracking of the gel balls is avoided, and the yield is greatly improved.
Preferably, the liquid inlet 1-1 is located above the filter screen 4 to prevent the gel beads from entering the liquid inlet 1-1.
Preferably, the self-circulation outlet 1-3 is located above the self-circulation inlet 1-4 to increase the turbulence effect caused by the flow of ammonia in the tank 1.

Wherein the ball valve may be, but is not limited to, a roll-down ball valve. The advantages of such an arrangement are: on one hand, the gel balls can slide to the discharge port 1-6 along the conical surface of the tank body 1 under the action of self gravity; on the other hand, because the ball valve top surface is the same level with the bottom surface of jar body 1 to not only can avoid gel ball and ball valve to bump and take place to warp, but also can avoid gel ball to remain in jar body 1.
Preferably, one end of the self-circulation inlet 1-4 is tangent to the conical surface of the tank body 1, and the other end is connected with the self-circulation pipeline 3. Therefore, when the self-circulation pump 6 is started, the ammonia water pumped out from the tank body 1 by the self-circulation pump 6 can flow into the tank body 1 along the inner wall of the tank body 1 through the self-circulation inlets 1-4 and can not be directly sprayed onto the gel balls in the tank body 1, and further the gel balls are prevented from being deformed due to water flow impact.
Further, the device also comprises a liquid inlet pump 7, and the liquid inlet pump 7 is communicated with the tank body 1 through a liquid inlet 1-1.
