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

[0022] Refer to Figures 1-4 , an embodiment provided by the present invention: A flame retardant masterbatch dryer for drum-type ABS includes a support base 2. The number of support bases 2 is two and they are arranged axially symmetrically. A drying drum 1 is fixedly connected to the support base 2. An end plate 101 is fixedly connected to the end of the drying drum 1. An air outlet pipe 9 is fixedly connected to the right end plate 101. The air outlet pipe 9 is located outside the air inlet pipe 10. A hot air assembly is arranged outside the drying drum 1. The hot air assembly includes a support frame 7 arranged outside the drying drum 1. A hot air blower 8 is fixedly installed on the support frame 7. The air outlet end of the hot air blower 8 is fixedly connected to the air inlet pipe 10. The air inlet pipe 10 is communicated with the drying drum 1;

[0023] During hot air drying operation, the hot air blower 8 is powered on to work, and the hot air flow is introduced into the drying drum 1 through the air inlet pipe 10 to perform hot air drying on the raw materials inside, and the dried air flow can be discharged to the outside through the air outlet pipe 9.

[0024] A discharge pipe 3 and a feeding pipe 11 are fixedly connected to the left end plate 101. The discharge pipe 3 is located below the feeding pipe 11. A control valve is fixedly installed on the discharge pipe 3. The upper end of the feeding pipe 11 is fixedly connected to a feeding hopper 12. A heat preservation layer 4 is fixedly connected to the upper part of the drying drum 1. A plurality of electric heating pipes are fixedly connected inside the heat preservation layer 4. A temperature controller 5 is fixedly installed on the right end plate 101. The temperature controller 5 is electrically connected to the electric heating pipes. A driving motor 13 is fixedly connected to the support seat 2. A driving shaft 14 is rotatably installed inside the drying drum 1. A plurality of pushing members 15 are arranged on the driving shaft 14. The driving motor 13 drives the driving shaft 14 to rotate through a transmission assembly 6. The transmission assembly 6 includes a driving belt pulley 603 and a driven belt pulley 601. A connecting belt 602 is arranged between the driving belt pulley 603 and the driven belt pulley 601. The driving belt pulley 603 is fixedly connected to the output end of the driving motor 13. The driven belt pulley 601 is fixedly connected to the driving shaft 14;

[0025] Through the feeding hopper 12 and the feeding pipe 11, the raw materials to be dried can be added into the drying drum 1. The dried raw materials can be discharged from the discharge pipe 3. The temperature controller 5 is powered on to work and can control the electric heating pipes to work, heating the top wall of the drying drum 1 to heat and dry the raw materials. The driving motor 13 is powered on to work and can drive the driving belt pulley 603 to rotate. The driving belt pulley 603 drives the driven belt pulley 601 through the connecting belt 602. The driven belt pulley 601 drives the driving shaft 14 to rotate. The driving shaft 14 drives a plurality of pushing members 15 to rotate, which can disperse the raw materials and push them to the top wall part of the drying drum 1.

[0026] The pushing member 15 includes a mounting plate 1504 fixedly installed on the driving shaft 14. A rotating seat 1503 is fixedly connected to the mounting plate 1504. A pushing plate 1502 is rotatably connected to the rotating seat 1503. A driving column 1501 is fixedly connected to the lower end of the pushing plate 1502. The driving column 1501 is in contact with the inner wall of the drying drum 1. A spring 1505 is fixedly connected between the pushing plate 1502 and the mounting plate 1504.

[0027] The pushing member 15 is used to push and disperse the raw materials. Under the elastic force of the spring 1505, the pushing plate 1502 and the driving column 1501 can drive a part of the raw materials to move. Excessive raw materials will cause the spring 1505 to deform and its length to increase, so that the excess raw materials will fall, ensuring an appropriate amount of raw materials being pushed up and uniform drying.

[0028] By providing the electric heating pipes and the temperature controller 5, heat can be provided to the upper part of the drying drum 1, thus providing the heat required for drying the internal raw materials. The provided pushing member 15 can evenly push the raw materials to the upper part of the drying drum 1 and cooperate with the hot air flow, thereby improving the drying efficiency and being convenient to use.

[0029] Working principle: During use, the raw materials to be dried can be added into the drying drum 1 through the feeding hopper 12 and the feeding pipe 11. The temperature controller 5 is powered on to control the operation of the electric heating tube, heating the top wall of the drying drum 1 to heat and dry the raw materials. The driving motor 13 is powered on to drive the rotation of the driving pulley 603. The driving pulley 603 drives the driven pulley 601 through the connecting belt 602. The driven pulley 601 drives the driving shaft 14 to rotate, and the driving shaft 14 drives a plurality of pusher parts 15 to rotate, which can disperse the raw materials and push them to the top wall part of the drying drum 1. The pusher parts 15 are used to push and disperse the raw materials. Under the elastic force of the spring 1505, the pusher plate 1502 and the driving column 1501 can drive part of the raw materials to move. Excessive raw materials will cause the spring 1505 to deform and its length to increase, so that the excess raw materials will fall, ensuring an appropriate amount of raw materials pushed up and uniform drying. At the same time, during the hot air drying operation, the hot air blower 8 is powered on, and the hot air flow is introduced into the drying drum 1 through the air inlet pipe 10 to conduct hot air drying on the internal raw materials. And the dried air flow can be discharged to the outside through the air outlet pipe 9. These two drying methods can improve the overall drying efficiency. The dried raw materials are discharged from the discharge pipe 3.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
