The inner drum is provided with a feeding port, the outer drum is provided with a discharging port, and a conical material guide joint which matches the discharging port is provided at the end of the middle drum. The material enters from the spiral guide plate of the inner drum feeding port, and is continuously lifted and longitudinally moved by the lifting plate of the inner drum under the rotation of the drum body, so as to realize downstream drying. The material falls into the middle drum by the action of its own weight at the other end of the inner drum, and moves longitudinally to the other end of the middle drum under the action of the lifting plate of the middle drum, so as to realize countercurrent drying. The material falls into the outer drum by the action of its own weight at the other end of the middle drum, and moves longitudinally to the other end of the outer drum under the action of the lifting plate of the outer drum, and is guided to the discharging port under the action of the conical material guide joint and its material guide plate. The distance between the cover plate of the existing discharging pipe and the conical material guide joint of the middle drum is fixed, and the distance cannot be effectively adjusted for materials of different particle sizes, and blocking is prone to occur. Therefore, a conical material guide joint of the middle drum of the three-drum dryer is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-6 As shown, the utility model is a discharge end cover plate adjustment mechanism of a three-drum dryer, comprising an outer drum 1, a middle drum 10 and an inner drum 11, wherein the middle drum 10 is concentrically mounted inside the outer drum 1, and the inner drum 11 is concentrically mounted inside the middle drum 10, and support rods 12 are fixedly arranged between the inner and outer side walls of the middle drum 10 and the inner and outer side walls of the outer drum 1 and the inner and outer side walls of the inner drum 11, and a plurality of circumferentially distributed lifting plates 13 are fixedly arranged on the inner side walls of the outer drum 1, the middle drum 10 and the inner drum 11, and a sealing material lifting plate 13 is fixedly arranged on the left side of the middle drum 10. A sealing plate 14, a feed pipe 15 is fixedly arranged on the right side of the inner cylinder 11, a circular plate 16 matching the feed pipe 15 is fixedly arranged on the right side of the outer cylinder 1, a conical cylinder 17 is fixedly arranged on the left side of the middle cylinder 10, a cover plate 18 is slidably mounted on the left side of the outer cylinder 1, a discharge pipe 19 matching the conical cylinder 17 is fixedly arranged on the cover plate 18, a cylinder 20 is fixedly arranged on the right side of the cover plate 18, an annular groove 21 matching the outer cylinder 1 is opened on the right side of the cylinder 20, and a control component matching the cover plate 18 is arranged on the outer cylinder 1;

[0022] During the use of the utility model, a hot air blower is arranged on the right side of the feed pipe 15, and hot air is continuously blown from the feed pipe 15 to the inner cylinder 11. A driving device is installed on the lower side of the outer cylinder 1, so that the outer cylinder 1, the middle cylinder 10 and the inner cylinder 11 rotate synchronously. A plurality of material shifting plates are fixedly installed on the inner walls of the outer cylinder 1, the middle cylinder 10 and the inner cylinder 11. When the material flows from the inner cylinder 11 through the middle cylinder 10 and the outer cylinder, the material is dried, and the material shifting plates turn the material to accelerate the drying speed of the material.

[0023] When the utility model is used, when drying different materials, it is necessary to adjust the distance between the cover plate 18 and the conical cylinder 17. When the user controls the cover plate 18, the cover plate 18 moves, and the cover plate 18 drives the cylinder 20 and the discharge pipe 19 to move synchronously, thereby changing the distance between the cover plate 18 and the conical cylinder 17, avoiding the blockage of the materials, and facilitating the discharge of different materials.

[0024] The utility model changes the distance between the cover plate and the left side of the outer cylinder through the control part to adapt to the smooth discharge of different materials, and the annular groove of the cylinder abuts against the inner and outer side walls of the outer cylinder, thereby ensuring the internal air tightness, ensuring that the gas and material flow in the normal direction, avoiding the blockage of the material, and improving the convenience of use.

[0025] The control assembly includes a plurality of circumferentially distributed blocks 22 fixedly provided on the side wall of the cover plate 18, a screw 23 being fixedly provided on the right side of the plurality of blocks 22, a plurality of circumferentially distributed support blocks 230 being fixedly provided on the outer side wall of the outer cylinder 1, a plurality of support blocks 230 being provided with round holes matching the screw 23, a first gear 24 being rotated together between two adjacent support blocks 230 on the left and right, a plurality of first gears 24 being provided with threaded holes matching the screw 23, a gear ring 25 meshing with the plurality of first gears 24 being rotated together between the adjacent support blocks 230 on the left and right;

[0026] During the use of the utility model, when the cover plate 18 needs to be adjusted, the user first directly rotates the ring gear 25, and the ring gear synchronously drives the first gears 24 to rotate, and the first gears 24 synchronously drive the screw rods 23 to move through the threaded holes, and the screw rods 23 drive the cover plate 18 to move through the square rods 23. The structure is simple and reasonable, and it is convenient for users to operate.

[0027] Two square rods 30 symmetrically distributed on the outer wall of the outer cylinder 1 are fixedly provided. The two square rods 30 are equipped with a rotating shaft for common rotation. The rotating shaft is coaxially fixed with a second gear 31 meshing with the gear ring 25. Elliptical rods 32 are fixedly provided on both sides of the rotating shaft. The two elliptical rods 32 are arranged in opposite directions. The outer walls of the two elliptical rods 32 are rotatably equipped with handles 33.

[0028] During the use of the present invention, when the user needs to rotate the ring gear 25, the user holds the two handles 33 at the same time to rotate them. The two handles 33 drive the second gear 32 to rotate through the elliptical rod 32, and the second gear 32 synchronously drives the ring gear 25 to rotate, thereby improving the operating convenience of the device.

[0029] The inner wall of the cylinder 20 is processed into an arc shape matching the discharge pipe 19, so as to facilitate the discharge of the material reaching the left side of the outer cylinder 1.

[0030] A plurality of arc-shaped plates 40 distributed in a circumference are fixedly provided on the inner wall of the cylinder 20 to accelerate the discharge of the material, avoid the material from being blocked on the left side of the outer cylinder 1, and improve the drying efficiency of the device for the material.

Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
