DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figures 1-5 The present application provides a technical solution: a drying device for mixed fertilizer granules, which comprises a drying cylinder 1, a hot air blower 2 placed behind the drying cylinder 1, a Y-shaped air duct 201 fixedly connected to the output end of the hot air blower 2, the other two ends of the Y-shaped air duct 201 connected to the two sides of the drying cylinder 1 respectively, a funnel-shaped screen 3 fixedly connected inside the drying cylinder 1, an opening formed at the lower end of the funnel-shaped screen 3, a discharge pipe 301 fixedly connected at the opening, a conical dispersion shell 4 arranged inside the drying cylinder 1 and above the funnel-shaped screen 3, and a feeding hopper 103 fixedly connected to the upper end of the drying cylinder 1.

[0022] In the present embodiment, the granular feed can be added to the inside of the drying cylinder 1 by using the feeding hopper 103, the hot air is blown into the inside of the drying cylinder 1 by starting the hot air blower 2, the sharp corner at the upper end of the conical dispersion shell 4 is located below the feeding hopper 103, and thus the feed added to the inside of the drying cylinder 1 by the feeding hopper 103 falls onto the conical dispersion shell 4. The hot air blower 2 is conical in shape, which disperses the falling feed to all around and makes it fall onto the funnel-shaped screen 3, so as to avoid the feed from falling into the funnel-shaped screen 3 in a concentrated manner. The feed passes through the edge of the funnel-shaped screen 3 and re-converges to the center, and in the process of rolling and converging in the funnel-shaped screen 3, the impurities are separated from the feed granules. At the same time, the hot air blown into the drying cylinder 1 dries the feed, and the feed granules finally fall into the discharge pipe 301 from the opening at the lower end of the funnel-shaped screen 3, and are discharged through the discharge pipe 301. The separated impurities fall into the bottom of the drying cylinder 1 and are collected, and are uniformly collected and treated later.

[0023] Wherein, in order to realize the purpose of cleaning accumulated debris, the device uses the following technical solutions to achieve: the lower surface of the drying cylinder 1 is fixedly connected with a supporting leg 101, the front surface of the drying cylinder 1 is provided with a discharge port, a discharge door 102 is rotatably installed in the discharge port, and a collecting inclined plate 104 is fixedly connected inside the drying cylinder 1 and below the funnel-shaped screen 3.

[0024] The drying cylinder 1 is supported by the supporting leg 101 to be away from the ground, so that there is a certain space below the drying cylinder 1 to place the collecting device. The collecting inclined plate 104 can make the falling debris converge towards the discharge port, which is convenient for cleaning the accumulated debris later. The discharge door 102 can block the discharge port to prevent the hot air inside the drying cylinder 1 from overflowing from the discharge port.

[0025] Wherein, in order to realize the purpose of making the feed evenly enter the drying cylinder 1, the device uses the following technical solutions to achieve: the outer edge of the conical dispersion shell 4 is fixedly connected with a threaded connecting rod 401 through a supporting leg, a through hole is formed in the upper surface of the drying cylinder 1, the threaded connecting rod 401 is slidably installed in the through hole, a fixed nut 402 is threadedly installed on the threaded connecting rod 401, a connecting ring 403 is fixedly connected to the upper end of the fixed nut 402, a pair of handles 404 are symmetrically fixedly connected to the upper surface of the connecting ring 403, an exhaust pipe 405 is fixedly connected to the upper surface of the conical dispersion shell 4, the exhaust pipe 405 is the same as the inside of the conical dispersion shell 4, a plurality of conical disturbance rings 406 are fixedly connected to the exhaust pipe 405, and the conical disturbance rings 406 are located in the feeding hopper 103.
