Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] Example 1:

[0043] like Figures 1 to 3 As shown, a double cone dryer includes:

[0044] Mounting base 1, two sets of mounting base 1 are symmetrically arranged;

[0045] The drying barrel 2 has tapered ends along its axial direction and is rotatably mounted on two sets of mounting bases 1 via bearing seats. The barrel wall of the drying barrel 2 is heated and the interior is vacuumed.

[0046] The power mechanism 3 is mounted on a set of mounting bases 1, and the power mechanism 3 drives the drying barrel 2 to rotate about its radial center;

[0047] Material feeding mechanism 4, which can be expanded and contracted, and several sets of material feeding mechanisms 4 extend along the axial direction of the drying barrel 2 and are distributed in a circumferential array inside the drying barrel 2.

[0048] And a drive mechanism 5, which is poweredly connected to several sets of feeding mechanisms 4 and drives several sets of feeding mechanisms 4 to move synchronously;

[0049] The poking mechanism 4 comprises a guide unit 41 extending axially along the drying barrel 2, two groups of poking units a 42 arranged on the guide unit 41 and corresponding to the tapered region of the drying barrel 2, a poking unit b 43 arranged between the two groups of poking units a 42, and a moving unit 44 arranged at the middle position of the guide unit 41 and driving the poking units a 42 and the poking unit b 43.

[0050] It should be noted that the barrel wall heating arrangement of the drying barrel 2 and the internal vacuum extraction thereof are prior art, and the present application does not make redundant description.

[0051] It is worth mentioning that the drying barrel 2 rotates 10°, and the poking mechanism 4 will contract and expand five times. When the drying barrel 2 rotates to its axis horizontal, the internal material is mostly concentrated in the middle part, at which time the expansion and contraction of the poking unit b 43 will sufficiently stir the material. Similarly, when the drying barrel 2 rotates to its axis vertical, the internal material is mostly concentrated in the tapered region thereof, and the expansion and contraction of the poking unit a 42 will sufficiently stir the material.

[0052] It should be further noted that the rotational speed of the drying barrel 2 is always kept constant, and the contraction and expansion times of the poking mechanism 4 can be accelerated or reduced.

[0053] Further, as shown in Figure 1 and Figure 2 The power mechanism 3 comprises a motor a 31 arranged at the bottom of the mounting seat 1, a speed reducer 32 arranged on the mounting seat 1 and power-connected with the motor a 31 through a belt transmission unit, a driving gear 33 arranged at the power output end of the speed reducer 32, and a driven gear 34 coaxially installed on the rotating shaft of the drying barrel 2 and meshed with the driving gear 33.

[0054] It should be noted that the motor a 31 is a three-phase asynchronous motor, which drives the speed reducer 32 to drive the driving gear 33 to rotate, and the driving gear 33 drives the driven gear 34 and the drying barrel 2 to rotate.

[0055] Further, as shown in Figure 5 The guide unit 41 comprises two groups of optical axes 411 arranged in parallel and axially along the drying barrel 2.

[0056] Further, as shown in Figure 5As shown in the figure, the material stirring unit a42 comprises an end plate 421 arranged away from the material stirring unit b43 and on the two groups of light axes 411, a moving plate 422 slidingly arranged on the two groups of light axes 411 and connected with the moving unit 44, and a plurality of groups of elastic rods a423 arranged in a circumferential array and between the end plate 421 and the moving plate 422.

[0057] Further, the material stirring unit b43 comprises a plurality of groups of elastic rods b431 arranged in a circumferential array and connecting the two groups of moving plates 422.

[0058] Further, the length of the elastic rods b431 is longer than the length of the elastic rods a423.

[0059] It should be noted that the arrangement of the elastic rods a423 and the elastic rods b431 is determined according to the proportion of the conical area in the drying barrel 2, so as to better stir the material in the drying barrel 2.

[0060] Further, as shown in the figure, Figure 5 the moving unit 44 comprises a bearing seat 441 arranged on the outer wall of the drying barrel 2, a forward and reverse lead screw 442 rotatably installed on the bearing seat 441 and located between the two groups of light axes 411, a lead screw nut 443 arranged on the forward and reverse lead screw 442 and connected with the moving plate 422, and a gear a444 arranged at the end of the forward and reverse lead screw 442.

[0061] It should be noted that the rotation of the forward and reverse lead screw 442 causes the two groups of lead screw nuts 443 to move closer to or away from each other, thereby causing the moving direction of the plurality of groups of elastic rods a423 and the elastic rods b431 to be opposite to each other.

[0062] Further, as shown in the figures, Figure 5 and Figure 8 a telescopic sheath 420 is arranged between the end plate 421 and the moving plate 422 and between the two groups of moving plates 422, and the telescopic sheath 420 is arranged on the outer side of the forward and reverse lead screw 442, which can be telescopically arranged and can effectively prevent dust in the drying barrel 2 from adhering to the surface of the forward and reverse lead screw 442.

[0063] Further, as shown in the figure, Figure 4As shown, the drive mechanism 5 includes rack mounting seats 51 arranged in a circumferential array and mounted on the outer wall of the drying barrel 2, a gear ring 52 rotatably mounted on several sets of rack mounting seats 51 and meshing with several sets of gears a444, a motor bracket 53 mounted on the outer wall of the drying barrel 2, a motor b54 mounted on the motor bracket 53, and a gear b55 mounted on the power output end of the motor b54 and meshing with the gear ring 52.

[0064] Furthermore, such as Figure 7 As shown, the rack mounting base 51 includes a vertical plate 511 mounted on the drying barrel 2, a mounting plate 512 disposed on the vertical plate 511, a mounting groove 513 horizontally opened on the mounting plate 512 and capable of accommodating the gear ring 52, and two sets of rollers 514 rotatably mounted in the mounting groove 513 and tangent to the outer ring of the gear ring 52.

[0065] It should be noted that the motor b54 is a servo motor, which better controls the rotation speed of the forward and reverse lead screws 442.

[0066] It should also be noted that the meshing of the gear ring 52 and several sets of gears a444 makes the rotation of the forward and reverse lead screw 442 more consistent.

[0067] It is important to note that the toothed ring 52 is installed inside the mounting groove 513, and the toothed ring 52 rotates in the area formed by several sets of rollers 514, and the toothed ring 52 is radially limited.

[0068] It is worth mentioning that the inlet and outlet of the drying barrel 2 described in this utility model are unobstructed, and when the drying barrel 2 is in the vertical discharge state, the several sets of elastic rods a423 and elastic rods b431 can also contract and expand, which is beneficial for discharge.

[0069] Example 2:

[0070] like Figure 6 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0071] The elastic rods a423 and b431 are spirally arranged at their intermediate positions.

[0072] It should be noted that the spiral design can further increase the contact area between the material and the spiral, thereby improving the material feeding effect and efficiency.

[0073] More need to explain is, the spiral setting is conducive to the bending of the elastic rod a423 and the elastic rod b431.

[0074] It is worth mentioning that, as Figure 6 The elastic rod a423 and the elastic rod b431 continue to deform after contacting the inner wall of the drying barrel 2, the contact position is reduced, and the material can be deeply stirred, the dead angle is reduced, and the stirring effect is improved.

[0075] Working process:

[0076] The material to be dried is placed in the drying barrel 2, the power mechanism 3 drives the drying barrel 2 to rotate, at the same time, the motor b54 drives the forward and reverse screw rod 442 to rotate, and then drives the two groups of screw nut 443 to move, and then drives the moving plate 422 to move, and then the moving plate 422 will cooperate with the end plate 421 to extrude or relax the elastic rod a423 to form the expansion and contraction state, and the two groups of moving plate 422 extrude or relax the elastic rod b431 to form the expansion and contraction state, the movement of the elastic rod a423 and the elastic rod b431 will produce the stirring of the material, the elastic rod a423 will stir and mix the material accumulated in the tapered region of the drying barrel 2, and the elastic rod b431 will stir and mix the material in the middle region of the drying barrel 2; when discharging, the elastic rod a423 and the elastic rod b431 can also be contracted and expanded, facilitating the discharge.

[0077] The above only for the preferred embodiment of the present application, and not to limit the present application, any modification, equivalent replacement and improvement within the spirit and principles of the present application, should be included in the protection scope of the present application.
