DETAILED DESCRIPTION

[0028] In order to make the objects, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0029] The inventor found through analysis of the prior art that the existing auxiliary agent adding method is to manually weigh the auxiliary agent and pour it into a high-speed mixer, which cannot guarantee uniform dispersion of the auxiliary agent, and may cause powder agglomeration due to local excess of the auxiliary agent. In addition, it cannot guarantee consistent adding time of the auxiliary agent, and may cause inconsistent modification effect of the powder between different batches due to inconsistent mixing time of the auxiliary agent and the powder.

[0030] Referring to Figures 1-6 In an embodiment of the present application, an auxiliary agent atomization adding device for modifying powder production is provided, which comprises a support frame 10, a container 20, a cover 30, a feeding port ball valve 71, a funnel 40, an air pressure regulating valve 72, an air outlet ball valve 73, a discharging port ball valve 74, a pipe body 50 and an atomizing nozzle 60.

[0031] The container 20 is arranged on the support frame 10; the cover 30 is arranged at the top opening of the container 20; the surface of the cover 30 is respectively provided with a feeding port, an air inlet and an air outlet; the feeding port ball valve 71 is arranged at the feeding port; the funnel 40 is arranged above the feeding port; the air pressure regulating valve 72 is arranged at the air inlet and connected with an air inlet device through an air inlet pipe; the air outlet ball valve 73 is arranged at the air outlet; the bottom of the container 20 is provided with a discharging port; the discharging port ball valve 74 is arranged at the discharging port; one end of the pipe body 50 is connected with the discharging port, and the other end is connected with the atomizing nozzle 60.

[0032] By adopting the container 20 and the cover 30 to form a closed space, arranging the air pressure adjusting valve 72 on the surface of the cover 30, arranging the ball valve 74 at the bottom of the container 20, and connecting the atomizing nozzle 60 through the pipe body 50, the pressure inside the container 20 can be accurately adjusted, so that the additives are atomized into uniform small particles and released into the high-speed mixer at a balanced speed within the set pressure range, thereby avoiding the phenomenon of powder agglomeration caused by uneven dispersion of additives, and reducing the difference in addition time of different batches of additives, and improving the quality stability of modified powder.

[0033] In the following, the additive atomization and addition device in the present exemplary embodiment will be further described.

[0034] In an embodiment of the present application, the additive atomization and addition device further comprises a pull rod buckle 81 and a lock buckle seat 82; the lock buckle seat 82 is arranged on the side of the container 20; one end of the pull rod buckle 81 is connected with the edge of the cover 30, and the other end is buckled with the lock buckle seat 82. By arranging the pull rod buckle 81 and the lock buckle seat 82, the cover 30 can be stably connected with the container 20 under high pressure conditions, preventing air pressure leakage or the cover 30 from falling off, and improving the safety of the device.

[0035] In an embodiment of the present application, the surface of the cover 30 is provided with a sealing groove; the inside of the sealing groove is provided with a sealing ring 31; the cover 30 is connected with the edge of the opening at the top of the container 20 through the sealing ring 31. By arranging the sealing ring 31, the airtightness of the container 20 can be improved, which provides a guarantee for maintaining the stability of the air pressure inside the container 20; in combination with the embedded design of the sealing groove, the sealing ring 31 can be uniformly stressed when compressed, further improving the sealing performance.

[0036] In an embodiment of the present application, the side of the air pressure adjusting valve 72 is provided with a first adjuster for adjusting the air inlet amount. The first adjuster can indirectly adjust the air pressure inside the container 20 by controlling the flow of gas entering the container 20. By arranging the first adjuster, the operator can easily adjust the flow of gas entering the container 20, ensuring that the air pressure inside the container 20 is within the set range.

[0037] In an embodiment of the present application, the side of the air pressure adjusting valve 72 is provided with an air pressure gauge for displaying the air pressure state. The air pressure gauge can intuitively provide the air pressure data inside the container 20 through pointer or digital display.

[0040] In an embodiment of the present application, the end of the atomization nozzle 60 is provided with a second adjuster for adjusting the caliber of the nozzle. By adjusting the caliber of the nozzle, the size of the atomized auxiliary agent particles can be adjusted: when the caliber of the nozzle is large, the particles of the auxiliary agent when sprayed are relatively large, which is suitable for processes with low powder covering requirements; when the caliber of the nozzle is small, the particles of the auxiliary agent when sprayed are relatively small, which is suitable for processes with high powder covering requirements. By arranging the second adjuster, the requirements of different modification processes on the size of the atomized particles can be flexibly adapted.

[0041] In an embodiment of the present application, the end of the pipe body 50 is provided with an elbow joint 51; and the pipe body 50 is connected with the discharge port through the elbow joint 51.

[0045] Close the air release ball valve 73 to ensure that the container 20 forms a closed space inside; open the air pressure regulating valve 72, adjust the gas flow into the container 20 through the first regulator, and monitor the air pressure inside the container 20 in real time through the air pressure gauge to confirm that the air pressure is within the preset range; according to the need for auxiliary agent atomization, adjust the caliber size of the atomizing nozzle 60 through the second regulator to control the size and spraying range of the atomized particles;

[0046] Open the discharging port ball valve 74, and the auxiliary agent flows through the elbow joint 51 and the pipe body 50 under the action of pressure, enters the atomizing nozzle 60, and is uniformly atomized through the atomizing nozzle 60 and sprayed into the high-speed mixer. After the addition of the auxiliary agent is completed, the discharging port ball valve 74 is closed.

[0047] Close the air pressure regulating valve 72 and open the air release ball valve 73. After the pressure inside the container 20 returns to normal pressure, loosen the pull rod buckle 81, open the cover 30, and clean the residual auxiliary agent inside the container 20 and the pipe body 50.
