[0006] In the preferred scheme, the scraping device comprises a mounting frame, a channel for the granulation is arranged in the mounting frame, and an adjustable-height scraper is arranged above the channel.

[0007] In the preferred scheme, a screw rod is arranged above the mounting frame, a through hole is arranged on the scraper, the through hole is sleeved on the screw rod, and nuts are arranged on the screw rod above and below the through hole.

[0008] In the preferred scheme, a guide groove is arranged in the mounting frame, and the scraper moves in the guide groove.

[0009] In the preferred scheme, a ventilation hole is arranged on the support frame, an air pipe is arranged above the ventilation hole, and the air blower is mounted on the air pipe.

[0010] In the preferred scheme, the support frame is in an open structure in the front-rear direction and in a closed structure in the left-right direction.

[0011] In the preferred scheme, a wind-passing net is fixedly sleeved on the inner wall below the air pipe.

[0012] In the preferred embodiment, a guide plate is provided inside the support frame, and the guide plate is located above the conveyor belt.

[0013] The beneficial effects of this utility model are as follows: Because this utility model is equipped with a granulator cooling and drying device, by setting a scraper device in front of the conveyor belt, the granules before entering the conveyor belt can be scraped flat, preventing the granules from piling up, which is conducive to the air carrying away the heat on the surface of the granules and improving the cooling efficiency.

[0021] Please see Figures 1-5 As shown, this application provides a technical solution: a granulator cooling and drying device, including a granulator 1, a chute 2 fixedly connected to the discharge port of the granulator 1, a conveyor belt 8 below the chute 2, a support frame 7 fixed above the conveyor belt 8, a blower 3 above the support frame 7, and a scraping device 4 for leveling the granulation material above the conveyor belt 8, the scraping device 4 being disposed between the chute 2 and the support frame 7.

[0022] In a preferred embodiment, the scraping device 4 includes a mounting frame 41, a granulation channel 411 is provided inside the mounting frame 41, and an adjustable-height scraper 42 is provided above the channel 411.

[0023] In this way, the granules enter the conveyor belt 8 through the channel 411, and then the height of the scraper 42 is adjusted to flatten the stacked granules. This allows the blower 3 to blow the granules to the bottom layer. The heat dissipation of the granules is faster than that of the stacking, which improves the heat dissipation efficiency of the equipment.

[0024] In a preferred embodiment, a screw 43 is provided above the mounting bracket 41, a through hole 431 is provided on the scraper 42, the through hole 431 is fitted onto the screw 43, and a nut 44 is provided on the screw 43 above and below the through hole 431.

[0025] When it is necessary to adjust the height of scraper 42, first loosen nut 44, move scraper 42 to the desired height, and then tighten nut 44 to fix the position of scraper 42.

[0026] In a preferred embodiment, a guide groove 412 is provided in the mounting bracket 41, and the scraper 42 moves within the guide groove 412.

[0027] In a preferred embodiment, a ventilation hole 71 is provided on the support frame 7, and an air duct 5 is provided above the ventilation hole 71. The blower 3 is installed on the air duct 5.

[0028] In the preferred embodiment, the support frame 7 is an open structure in the front-to-back direction and a closed structure in the left-to-right direction.

[0029] This allows the air from the hairdryer 3 to blow out from the front and back without affecting the sides.

[0030] In the preferred embodiment, a ventilation mesh 9 is fixedly fitted on the inner wall below the duct 5.

[0031] In a preferred embodiment, a guide plate 10 is provided inside the support frame 7, and the guide plate 10 is located above the conveyor belt 8.

[0032] The air guide plate 10 is arranged along the length of the support frame 7, mainly to allow the generated air to blow onto the conveyor belt 8.

[0033] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims.
