[0044] Motor No. 1 204, motor No. 1 204 is fixedly mounted on the box body 201;

[0045] The spiral conveying blade 205, the output end of the first motor 204 and one end of the spiral conveying blade 205 are fixed, the interior of the box 201 is fixedly connected with a conveying pipe, and the outer wall of the spiral conveying blade 205 is adapted to the outer wall of the conveying pipe;

[0046] The second vibrating screen 206 is fixedly installed inside the box 201 .

[0047] The stirring and heating component 3 comprises:

[0048] A heating tank 301, wherein the feeding end of the heating tank 301 and the discharging end fixedly mounted on the box body 201 are fixed to each other, and a heating device is fixedly connected to the interior of the heating tank 301;

[0049] No. 2 motor 302, which is fixedly mounted on the heating tank 301;

[0050] The stirring blade 303 is fixedly mounted on the output end of the second motor 302 .

[0051] A feeding funnel is fixedly connected to the top of the box body 201 , and a valve is installed between the discharge end of the heating tank 301 and the feed end of the extrusion granulator 4 .

[0052] The size of the sieve holes on the No. 1 vibrating screen 202 is the same as the size of the sieve holes on the No. 2 vibrating screen 206 , and a partition is fixedly connected to the bottom end of the No. 1 vibrating screen 202 .

[0053] A circular hole is provided at the top of the box body 201 , and the output end of the first motor 204 passes through the circular hole and penetrates the top of the box body 201 and the top of the spiral conveying blade 205 to be fixed.

[0054] A through hole is provided at the top of the heating tank 301 , and the output end of the second motor 302 passes through the through hole and penetrates the top of the heating tank 301 and the top of the stirring blade 303 to be fixed.

[0055] The material is fed into the box 201 through the feeding funnel. The flame retardant first passes through the No. 1 vibrating screen 202. The No. 1 vibrating screen 202 can also break the agglomerated flame retardant during the vibration process. After being screened by the No. 1 vibrating screen 202, the loose flame retardant will fall onto the partition and then fall onto the heating tank 301 along the partition. The agglomerated flame retardant is broken by the breaking device 203. The broken flame retardant falls onto the No. 2 vibrating screen 206 and is screened by the No. 2 vibrating screen 206. The loose flame retardant will fall onto the heating tank 301, while the still agglomerated flame retardant will move to the position of the spiral conveying blade 205, the output end of the No. 1 motor 204 rotates, the spiral conveying blade 205 rotates, the No. 1 motor 204, the spiral conveying blade 205 and the conveying pipe constitute a spiral conveying device, thereby being able to move the agglomerated flame retardant to the No. 1 vibrating screen 202, and the above operation is repeated. At the same time, the spiral conveying device also has a crushing effect on the agglomerated flame retardant during the conveying process.

[0056] The flame retardant falls into the heating tank 301, and the heating device is started to heat the flame retardant to melt it. At the same time, the output end of the second motor 302 rotates, and the stirring blade 303 rotates to stir the flame retardant, thereby ensuring that the flame retardant is heated evenly. The valve is opened to allow the flame retardant in the molten state to be moved to the extrusion granulator 4, and the granulation process of the flame retardant is completed through the extrusion granulator 4.

[0057] Through the setting of the crushing component 2, the agglomerated flame retardant and the loose flame retardant are separated by the No. 1 vibrating screen 202, so that the agglomerated flame retardant enters the crushing device 203 for crushing, and the loose flame retardant directly enters the heating tank 301. The No. 2 vibrating screen 206 is installed at the discharge end of the crushing device 203. The No. 2 vibrating screen 206 separates the flame retardant again, so that the loose flame retardant is in the heating tank 301, and the still agglomerated flame retardant is moved to the No. 1 vibrating screen 202 by the action of the spiral conveying blade 205. This method reduces the processing capacity of the crushing device 203, and at the same time, the crushed flame retardant is screened again, so that the still agglomerated flame retardant is moved to the No. 1 vibrating screen 202 again, thereby ensuring that the flame retardant entering the heating tank 301 is in loose state, and the melting effect of the flame retardant in the heating tank 301 is guaranteed.
