[0020] like Figures 1 to 4 As shown, the embodiment of the utility model proposes a flame retardant masterbatch screening machine, including a screening box 1, a placement slot 101 is provided at the lower end of the screening box 1, a plurality of storage boxes 2 are installed in the placement slot 101, a filter slot 102 is provided at the upper end of the placement slot 101, a filter mechanism 4 is installed in the filter slot 102, a feed port 5 is fixedly installed at the upper end of the filter slot 102, a plurality of filter holes 3 are respectively penetrated on the lower surface of the storage box 2, and the aperture of the filter holes 3 from top to bottom is set to be large The filtering mechanism 4 includes an air inlet pipe 402 and a recovery box 405. The air inlet pipe 402 is installed through the internal front end of the filter tank 102, and the recovery box 405 is installed at the upper end of the rear side of the screening box 1. A guide groove 406 is provided between the recovery box 405 and the filter tank 102, and the guide groove 406 is connected to the air inlet pipe 402. An air suction pipe 407 is installed through the internal upper end of the recovery box 405, the air inlet pipe 402 is connected to an external hair dryer, and the air suction pipe 407 is connected to an external suction fan.

[0021] like Figure 3 and Figure 4As shown, in another embodiment of the utility model, a fixing block 401 is fixedly installed on the upper end of the front surface of the screening box 1, a diffusion slot 404 is provided between the fixing block 401 and the filter slot 102, an air inlet pipe 402 is fixedly installed through the front end of the diffusion slot 404, the diffusion slot 404 and the guide slot 406 are parallel to each other, a guide plate 403 is fixedly installed on the upper end of the inner part of the filter slot 102, the upper end of the guide plate 403 is set to be inclined, the guide plate 403 and the feed port 5 are parallel to each other, a filter screen 408 is installed on the upper end of the inner part of the recovery box 405, and the filter screen 408 and the guide slot 406 are both set to be inclined, and The inclination angle is opposite, and a temporary storage box 409 is installed at the lower end of the interior of the recycling box 405. A positioning plate 410 is movably installed through the lower end of the interior of the temporary storage box 409. One side of the positioning plate 410 is installed in the interior of the positioning groove 414. The positioning groove 414 is arranged on one side of the interior of the recycling box 405. A groove 411 is arranged at the lower end of the interior of the temporary storage box 409. The positioning plate 410 is movably installed through the interior of the groove 411. A limiting plate 413 is fixedly installed at one end of the positioning plate 410 located in the interior of the groove 411, and a spring 412 is installed between the side of the limiting plate 413 away from the positioning groove 414 and the groove 411.

[0022] The user pours the raw material into the feed port 5, and allows it to fall into the filter tank 102 along the feed port 5. Then, when the raw material meets the guide plate 403, the raw material and the waste are initially separated by the splashing between the raw materials. Then, when the raw material flows downward along the guide plate 403, the hair dryer blows the air into the filter tank 102 along the air inlet pipe 402 and the diffusion groove 404, so that the wind force blows the impurities in the falling process toward the direction of the guide groove 406. At the same time, the suction machine adsorbs and guides the impurities blown over through the suction pipe 407 and the guide groove 406, so that the impurities follow the air along the guide groove 406 into the recovery box 405 to realize the impurity recovery work. Then, the filtered raw material can fall into the storage box 2. Finally, after the overall filtration of the raw material is completed, the screening box 1 can drive the storage box 2 to vibrate, so that the raw material can be screened and separated through the filter holes 3 of different diameters in each storage box 2.

[0023] The filter 408 is used to isolate the air suction pipe 407 from impurities, so as to prevent the impurities from drifting to the outside along the air suction pipe 407 and polluting the environment. Then, the filter 408 is set to be inclined to facilitate the impurities to slide along the filter 408 and fall into the temporary storage box 409 to wait for the later recycling work;

[0024] The guide groove 406 is set to be inclined to prevent the impurities from flowing along the guide groove 406 to the inside of the screening box 1 again during the vibration of the screening box 1, causing ineffective filtering;

[0025] After the user inserts the temporary storage box 409 into the recycling box 405, the spring 412 pushes the limit plate 413 to allow the limit plate 413 to drive the positioning plate 410 to be inserted into the positioning groove 414, thereby positioning the temporary storage box 409. Then, when the temporary storage box 409 needs to be taken out, it is only necessary to pull the positioning plate 410 to disengage the positioning plate 410 from the positioning groove 414, so that the temporary storage box 409 can be taken out, thereby making it convenient for the user to disassemble and install the temporary storage box 409 and to recover the impurities inside the temporary storage box 409.

[0026] The working principle of this flame retardant masterbatch screening machine:

[0027] When in use, the user first pours the raw material into the feed port 5, allowing it to fall into the filter tank 102 along the feed port 5, and then when the raw material meets the guide plate 403, the raw material and waste are initially separated by sputtering between the raw materials. Then, when the raw material flows downward along the guide plate 403, the hair dryer blows air into the filter tank 102 along the air inlet pipe 402 and the diffusion groove 404, allowing the wind to blow the impurities in the falling process toward the guide groove 406. At the same time, the suction machine adsorbs and guides the impurities blown over through the suction pipe 407 and the guide groove 406, allowing the impurities to follow the air along the guide groove 406 into the recovery box 405 to realize the impurity recovery work, and then the raw material after filtration can fall into the storage box 2. Finally, after the overall filtration of the raw material is completed, the screening box 1 can drive the storage box 2 to vibrate, so that the raw material can be screened and separated through the filter holes 3 of different diameters in each storage box 2.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
