The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0025] Refer to Figures 1-4 , an apparatus for accurately adding flame retardant with frequency conversion control according to an embodiment of the present utility model, which includes: a feeding hopper 1, a level sensor 101 is installed on the inner wall of the feeding hopper 1, a controller 102 is installed on the outer side wall of the feeding hopper 1, and the controller 102 is electrically connected to the motor 1 3, the motor 2 702, the motor 3 601, the electric switch valve 7011 and the level sensor 101. Four connecting columns 103 are fixedly connected to the lower part of the feeding hopper 1, and the four connecting columns 103 are symmetrically distributed. A feeding port 2 is arranged above the feeding hopper 1, a motor 1 3 is fixedly connected above the feeding hopper 1, the output end of the motor 1 3 is fixedly connected to a rotating shaft 4, a stirring rod 5 is fixedly connected to the outer side wall of the rotating shaft 4, the number of the stirring rods 5 is multiple, and the multiple stirring rods 5 are symmetrically distributed on the outer side wall of the rotating shaft 4 with the center of the rotating shaft 4 as the center. A cleaning component 6 is arranged below the feeding hopper 1, and an adding component 7 is arranged below the feeding hopper 1;

[0026] The adding component 7 includes a feeding pipe 701 fixedly connected to the lower part of the feeding hopper 1. An electric switch valve 7011 is arranged at the connection between the feeding pipe 701 and the feeding hopper 1, and the feeding pipe 701 is inclined. A motor 2 702 is fixedly connected to one side of the feeding pipe 701, the output end of the motor 2 702 is fixedly connected to a connecting shaft 703, and a screw blade 704 is fixedly connected to the outer side wall of the connecting shaft 703.

[0027] The cleaning component 6 includes a third motor 601 fixedly connected to the lower part of the feeding tank 1. The output end of the third motor 601 is fixedly connected with a rotating rod 602. Two first cleaning plates 603 are fixedly connected to the outer side wall of the rotating rod 602. Above one end of each first cleaning plate 603 away from the rotating rod 602, a second cleaning plate 604 is fixedly connected. Both the two first cleaning plates 603 and the second cleaning plates 604 are adapted to the inner bottom wall and the inner side wall of the feeding tank 1.

[0028] Working principle: First, when in use, the flame retardant is added into the feeding tank 1 through the feeding port 2. Before adding the flame retardant, the first motor 3 can be started to drive the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the stirring rod 5 to rotate, so as to stir the flame retardant to ensure its uniform distribution and prevent bridging or caking. Secondly, the device is in a interlocking state with the hot grinding section of the production line. When producing the flame retardant board, the feeding tank 1 is filled with the flame retardant and in a standby state. When the hot grinding system enters the production state, the flame retardant can be added. The electric switch valve 7011 is opened, and the second motor 702 is started to drive the connecting shaft 703 and the dragon blade 704 to rotate. The dragon blade 704 is used to evenly push the flame retardant out from the feeding pipe 701, so as to achieve precise control of the addition amount. In order to prevent the accumulation and residue of the flame retardant in the feeding tank 1, the third motor 601 can be started to output the rotating rod 602 to drive the first cleaning plates 603 and the second cleaning plates 604 to rotate. The residues on the inner wall of the feeding tank 1 can be effectively removed by the rotation of the first cleaning plates 603 and the second cleaning plates 604. When the output of the hot grinding system changes, the controller 102 can adjust the rotation speed of the second motor 702 at any time according to the output change, so as to timely and accurately control the addition amount of the flame retardant.
