The inclined-inlet feeding pipe assembly 1 enables the materials not to turn, so as to directly enter the horizontal drying assembly 2. Moreover, the inclined-inlet feeding pipe assembly 1 is arranged in an inclined manner, so that the materials are obliquely fed into the horizontal drying assembly 2. Since the materials do not turn, there is no situation of blockage in the feeding pipe.

[0061] In one embodiment, the included angle between the inclined-inlet feeding pipe assembly 1 and the horizontal drying assembly 2 is 140°.

[0062] The beneficial effect of the above technical solution is as follows:

[0063] The included angle between the inclined-inlet feeding pipe assembly 1 and the horizontal drying assembly 2 is 140°. Materials are fed from the inclined-inlet feeding pipe assembly 1 into the horizontal drying assembly 2. The inclined-inlet feeding pipe assembly 1 enables the materials not to turn, so as to directly enter the horizontal drying assembly 2.

[0064] In one embodiment, it further includes:

[0065] A feeding cover 11, the feeding cover 11 is installed on the horizontal drying assembly 2, and the inclined-inlet feeding pipe assembly 1 is installed inside the feeding cover 11.

[0066] In one embodiment, the inclined-inlet feeding pipe assembly 1 includes a feeding channel composed of a bottom plate 12 and a side plate 13, and both the bottom plate 12 and the side plate 13 are made of 310S material.

[0067] The beneficial effect of the above technical solution is as follows:

[0068] The inclined-inlet feeding pipe assembly 1 includes a feeding channel composed of a bottom plate 12 and a side plate 13, and both the bottom plate 12 and the side plate 13 are made of 310S material, so that the bottom plate 12 and the side plate 13 can withstand a temperature of 1150°C, are corrosion-resistant, and anti-sticking.

[0069] In one embodiment, the horizontal drying assembly 2 includes:

[0070] The cylinder body 21 is horizontally arranged, the feeding cover 11 is installed at one end of the cylinder body 21, and the inclined feeding pipe assembly 1 is connected to the inside of the cylinder body 21 from one end thereof;

[0071] The heating sleeve 22 is sleeved on the surface of the cylinder body 21;

[0072] The stirring assembly 23 is installed at the other end of the cylinder body 21;

[0073] The discharging assembly 24 is installed in the inclined feeding pipe assembly 1. The input end of the discharging assembly 24 extends into the cylinder body 21 and is connected to the stirring assembly 23;

[0074] The discharging port 25 is installed at the bottom end of the cylinder body 21, and a discharging valve 26 is installed on the discharging port 25.

[0075] The working principle and beneficial effects of the above technical solution are as follows:

[0076] Materials are fed into the cylinder body 21 from the inclined feeding pipe assembly 1. The heating sleeve 22 works, so that the materials located in the cylinder body 21 are heated and dried. The stirring assembly 23 works, thereby improving the fluidity of the materials in the cylinder body 21. The discharging assembly 24 is installed in the inclined feeding pipe assembly 1. When the stirring assembly 23 stirs in the cylinder body 21 to improve the fluidity of the materials, the materials fed into the cylinder body 21 from the inclined feeding pipe assembly 1 are under the action of the discharging assembly 24, and the discharging speed is increased.

[0077] In one embodiment, support legs 27 are installed at the bottom end of the cylinder body 21.

[0078] In one example, the stirring assembly 23 includes:

[0079] The fixed seat 31 is embedded and installed at the other end of the cylinder body 21;

[0080] The stirring seat 32 is embedded and installed on the fixed seat 31;

[0081] The avoidance groove 33 is formed on the stirring seat 32;

[0082] The stirring motor 34 is installed on the stirring seat 32 near the avoidance groove 33 through a motor mounting bracket;

[0083] The stirring shaft 35 is located in the cylinder body 21, and the stirring shaft 35 passes through the avoidance groove 33;

[0084] A resetable telescopic member 36, the resetable telescopic member 36 is located within the avoidance groove 33, and the resetable telescopic member 36 is connected between the stirring shaft 35 and the output end of the stirring motor 34;

[0085] Stirring pipes 37, a plurality of the stirring pipes 37 are circumferentially mounted on the stirring shaft 35 through connecting pipes;

[0086] Outer spiral blades 38, a plurality of the outer spiral blades 38 are mounted on the stirring pipes 37;

[0087] Friction blocks 39, the friction blocks 39 are mounted on the end of the stirring shaft 35 away from the resetable telescopic member 36, and the friction blocks 39 are connected to the blanking assembly 24;

[0088] Sealing disk 30, the sealing disk 30 is fixedly installed within the cylinder body 21 near the stirring base 32, and the stirring shaft 35 passes through the central end of the sealing disk 30.

[0089] The working principle and beneficial effects of the above technical solution are as follows:

[0090] The stirring motor 34 operates, thereby driving the stirring shaft 35, which is connected to the output end of the stirring motor 34 by the resetable telescopic member 36, to rotate within the cylinder body 21, thereby driving the stirring pipes 37, which are mounted on the stirring shaft 35 through connecting pipes, to rotate within the cylinder body 21. The stirring pipes 37 improve the fluidity of the materials within the cylinder body 21. The stirring shaft 35 drives the blanking assembly 24 to operate through the friction blocks 39, and the blanking assembly 24 operates within the obliquely inserted feed pipe assembly 1, improving the blanking speed.

[0091] A quantitative amount of materials is placed into the feed hopper 10. When the stirring motor 34 operates, while the stirring shaft 35 rotates, the resetable telescopic member 36 expands and contracts, thereby driving the stirring pipes 37, which are mounted on the stirring shaft 35 through connecting pipes, to rotate within the cylinder body 21 while moving periodically towards and away from the sealing disk 30. When the stirring pipes 37 move away from the sealing disk 30 within the cylinder body 21, the friction blocks 39 drive the blanking assembly 24 to rotate faster, thereby quickly driving the materials within the feed hopper 10 to be fed into the cylinder body 21 through the obliquely inserted feed pipe assembly 1. The materials fall and accumulate within the cylinder body 21 near the feed cover 11. As the outer spiral blades 38 rotate, while the materials gradually move towards the sealing disk 30, the stirring pipes 37 improve the fluidity of the materials. When the materials move to the discharge port 25 position, the discharge valve 26 discharges the materials.

[0092] And when the stirring pipes 37 move towards the sealing disk 30 within the cylinder body 21, the friction blocks 39 drive the blanking assembly 24 to rotate slower, thereby reducing the speed at which the materials within the obliquely inserted feed pipe assembly 1 are fed into the cylinder body 21, thus reducing the accumulation of materials at the position within the cylinder body 21 near the feed cover 11.

[0093] When the rotation speed of the feeding component 24 in the inclined feeding pipe assembly 1 is the slowest, the material temporarily stagnates in the feeding hopper 10. At this time, additives are added to the feeding hopper 10, and the additives and the material are retained in the feeding hopper 10, thereby providing a mixing time for the additives and the material. As the rotation speed of the feeding component 24 increases, the mixture of the additives and the material is sent into the cylinder body 21 from the inclined feeding pipe assembly 1 and accumulates near the feeding cover 11 in the cylinder body 21. At this time, as the outer spiral blade 38 rotates, the material gradually moves towards the direction close to the sealing disc 30. When the rotation speed of the feeding component 24 slows down, new material can continue to be filled into the feeding hopper 10. When the rotation speed of the feeding component 24 in the inclined feeding pipe assembly 1 is the slowest, the feeding of the material in the feeding hopper 10 stops, and the additives can be added again.

[0094] In one embodiment, the feeding component 24 includes:

[0095] A friction disc 41, which is installed at the top inside the cylinder body 21 through a first mounting shaft 42. The first mounting shaft 42 is vertically distributed with the stirring shaft 35, and the friction block 39 is connected to the friction disc 41;

[0096] A second mounting shaft 43, which is installed at the top inside the cylinder body 21 through a support frame. One end of the second mounting shaft 43 is provided with a friction ball 44, the friction ball 44 is connected to the friction disc 41, and the other end of the second mounting shaft 43 extends into the inclined feeding pipe assembly 1;

[0097] A feeding auger 45, which is located in the inclined feeding pipe assembly 1 and is installed on the second mounting shaft 43.

[0098] The working principle and beneficial effects of the above technical solution are:

[0099] When the friction block 39 rotates, it drives the first mounting shaft 42 to rotate through the friction disc 41. The friction disc 41 drives the second mounting shaft 43 to rotate in the inclined feeding pipe assembly 1 through the friction ball 44, thereby driving the feeding auger 45 installed on the second mounting shaft 43 to rotate to complete the feeding of the material. When the rotation speed of the feeding auger 45 slows down, the feeding speed of the material slows down, and when the feeding auger 45 stops rotating, the feeding of the material in the inclined feeding pipe assembly 1 stops.

[0100] When the turning diameter change of the friction block 39 and the friction disc 41 increases, the rotation speed of the friction disc 41 slows down. When the turning diameter change of the friction block 39 and the friction disc 41 decreases, the rotation speed of the friction disc 41 increases. When the friction block 39 disengages from the friction disc 41, the friction disc 41 stops rotating.

[0101] In one embodiment, the stirring assembly 23 further includes:

[0102] Wedge-shaped top blocks 46, a plurality of the wedge-shaped top blocks 46 are symmetrically installed at the end of the stirring base 32 away from the avoidance groove 33, and the wedge-shaped top blocks 46 are arranged in an arc shape;

[0103] Air bags 47, a plurality of the air bags 47 are circumferentially installed at the side end of the stirring base 32;

[0104] Central through hole, the central through hole is opened at the central end of the stirring base 32, and the stirring shaft 35 passes through the central through hole;

[0111] The working principle and beneficial effects of the above technical solutions are:

[0112] When the pressing rod 51 abuts against the wedge-shaped top block 46, the stirring shaft 35 moves away from the sealing disc 30. At this time, the pressing block 52 connected to the pressing rod 51 presses on the airbag 47, so that the air in the airbag 47 is sent from the air inlet channel 48 and the air inlet 40 into the air outlet channel located in the stirring shaft 35. The air in the air outlet channel is sent into the stirring tube 37 through the connecting pipe and discharged from the air outlet, blowing on the inner wall of the cylinder body 21, so that the materials adhering to the inner wall of the cylinder body 21 after drying fall off, reducing the adhesion of the materials on the inner wall of the cylinder body 21 and improving the fluidity of the materials in the cylinder body 21. When the pressing block 52 disengages from the airbag 47, the airbag 47 returns to its original state, so that the external air is sent into the airbag 47 and the air inlet channel 48 from the one-way valve and the air supplement channel 49. When the pressing rod 51 disengages from the wedge-shaped top block 46, under the action of the reset telescopic member 36, the stirring shaft 35 moves towards the sealing disc 30.

[0113] In one embodiment, the reset telescopic member 36 includes:

[0114] A fixed sleeve 53, the fixed sleeve 53 is installed at the output end of the stirring motor 34, and the stirring shaft 35 extends into the fixed sleeve 53;

[0118] The working principle and beneficial effects of the above technical solution are:

[0119] When the stirring motor 34 works, the stirring shaft 35 is driven to rotate through the fixed sleeve 53 connected to the output end of the stirring motor 34. When the stirring shaft 35 moves towards or away from the sealing disc 30, the return spring 56 correspondingly contracts or extends in the fixed sleeve 53.

[0120] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
