[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example 1: A high-efficiency and energy-saving drying tower, reference Figure 1 and Figure 2 , including a drying cylinder 1, and also including a bulk material mechanism, the mechanism includes a vibration material component and a separation component, wherein the vibration material component includes a first bulk material rack 8 and a second bulk material rack 9, wherein the first bulk material rack 8 and the second bulk material rack 9 are both provided with a plurality of discharge holes, through vibration and the limitation of the discharge holes, the auxiliary material is dispersed, the gap between the materials is increased, and the contact area between the materials and the hot air is increased, thereby improving the efficiency and quality of drying, wherein the first bulk material rack 8 and the second bulk material rack 9 are both umbrella-shaped (such as Figure 2As shown in the figure, the first bulk rack 8 and the second bulk rack 9 are symmetrically arranged. When the material enters the drying cylinder 1, it first falls on the first bulk rack 8. The first bulk rack 8 is in the shape of an umbrella. During the vibration of the first bulk rack 8, the material moves along the top wall of the first bulk rack 8 to its edge. During the movement, the material is helped to fall on the second bulk rack 9 below through the discharge hole. The second bulk rack 9 is in the shape of an inverted umbrella. The material falling on the second bulk rack 9 moves toward its center under the action of vibration and falls on the next first bulk rack 8 through the discharge hole on the second bulk rack 9. The interval between materials is increased through the multi-stage dispersion effect. The rotating tube 6 rotates When the first bulk rack 8 and the second bulk rack 9 vibrate reciprocatingly up and down, the first bulk rack 8 and the second bulk rack 9 are respectively connected to the inner wall of the drying cylinder 1 for sliding up and down. A through hole is provided at the center of the first bulk rack 8 and the second bulk rack 9, and the diameters of the two through holes are different. The material on the second bulk rack 9 moves toward its center under the action of vibration, so the through hole on the second bulk rack 9 can be larger than the through hole on the first bulk rack 8 to prevent the accumulation of materials. A guide rod is provided on the first bulk rack 8 and the second bulk rack 9, and a wavy guide groove (not shown in the figure) is provided on the side wall of the rotating tube 6. The guide rod is slidably installed in the guide groove.

[0022] Specifically, during the rotation of the rotating tube 6 , the guide rod will slide along the wavy guide groove, so that the guide rod floats up and down, thereby driving the first bulk rack 8 and the second bulk rack 9 to vibrate back and forth up and down.

[0023] like Figure 2 As shown, the separation component includes a rotating tube 6 rotatably installed in the drying cylinder 1, and hot air flows from bottom to top in the rotating tube 6. A hot air box 4 is provided on one side of the drying cylinder 1, and a fan and a heating component are provided in the hot air box 4. An air inlet pipe 5 is provided on one side of the hot air box 4. A transmission box 3 is provided at the bottom end of the rotating tube 6, and the transmission box 3 and the air inlet pipe 5 are connected. When the hot air flows, the rotating tube 6 rotates. A bottom cylinder 2 is provided at the bottom end of the drying cylinder 1, and the transmission box 3 is located in the bottom cylinder 2. A plurality of diversion holes are opened on the side wall of the rotating tube 6, and a wind wheel 7 is provided on the side wall of the bottom end of the rotating tube 6.

[0024] The hot air box 4 transports hot air to and from the transmission box 3 through a fan and a heating component, wherein the heating component can be a heating wire or other components, which mainly meets the heating needs and meets the actual needs. After the hot air enters the transmission box 3, it will blow the wind wheel 7 to rotate, and the wind wheel 7 drives the rotating tube 6 to rotate, and the hot air will enter the rotating tube 6, and then be dispersed into the drying cylinder 1 through the diverter hole on its side wall. The direction of the diverter hole can be not towards the center of the rotating tube 6, so that when the air flows out, it will squeeze the side wall of the diverter hole, thereby further accelerating the rotation of the rotating tube 6. Of course, the direction of squeezing needs to adapt to the direction of rotation of the wind wheel 7. The above-mentioned vibration and dispersing effect can be completed during the rotation of the rotating tube 6.

[0025] refer to Figure 2 as well as Figure 3 , a first dispersion rack 10 and a second dispersion rack 11 are provided on the rotating tube 6, the first dispersion rack 10 includes a fixed rod 101 fixedly connected to the rotating tube 6, and an upper distribution rack 102 and a lower distribution rack 103 slidably installed on the fixed rod 101 at one end away from the rotating tube 6, and a distribution comb is provided on the outer wall of the upper distribution rack 102 and the lower distribution rack 103 on the side close to each other. When the rotating tube 6 rotates, the upper distribution rack 102 and the lower distribution rack 103 intermittently move away from and approach each other, and the sliding connection between the upper distribution rack 102 and the lower distribution rack 103 and the fixed rod 101 is provided with a return spring, and at least one of the distribution rack 102 and the lower distribution rack 103 adopts an inclined sliding manner, and a plurality of guide racks 21 are provided on the inner wall of the drying cylinder 1, and the upper distribution rack 102 and the lower distribution rack 103 are squeezed by the inner wall of the guide rack 21 to approach each other.

[0026] The rotation of the rotating tube 6 will also drive the multiple first dispersion racks 10 and second dispersion racks 11 to rotate together. During the rotation process, the first dispersion racks 10 and the second dispersion racks 11 will respectively move the materials on the first bulk rack 8 and the second bulk rack 9 to help them pass through the corresponding discharge holes. At the same time, they can break up the materials and further expand the intervals between the materials. Secondly, the first dispersion racks 10 and the second dispersion racks 11 also have the function of separating materials that are stuck together. Specifically, taking the first dispersion rack 10 as an example, Figure 4 As shown, the first dispersion rack 10 includes an upper distribution rack 102 and a lower distribution rack 103. The materials adhered together are relatively large in size and cannot directly pass through the gap between the upper distribution rack 102 and the lower distribution rack 103. As the first dispersion rack 10 rotates, the upper distribution rack 102 and the lower distribution rack 103 will encounter the guide rack 21 installed on the inner wall of the drying cylinder 1, as shown in FIG. Figure 5 As shown, under the extrusion of the inner wall, the upper material distribution rack 102 and the lower material distribution rack 103 will approach each other. It is worth noting that the lower material distribution rack 103 will be staggered with the upper material distribution rack 102 while approaching the upper material distribution rack 102, thereby achieving the action of clamping and crushing the material, and the distance between the two will not be too close to prevent the material from being crushed (adjusted according to the specific type of material).

[0027] Example 2: like Figure 2 As shown, a plurality of feed holes 17 are provided on the top of the drying cylinder 1, and a feed pipe 18 is installed on each feed hole 17. A second grid 19 is movably inserted on the side wall of the feed pipe 18, and a cam 20 is fixedly sleeved on the top of the rotating tube 6. A slide groove is provided on the side wall of the cam 20, and a slider adapted to the slide groove is provided on the second grid 19. The first grid is fixedly installed in the feed pipe 18.

[0028] During the rotation of the rotating tube 6, the cam 20 will be driven to rotate. The sliding groove outside the cam 20 is adapted to the slider on the second grid 19, so that the cam 20 drives the second grid 19 to slide back and forth, so that the grid holes between the second grid 19 and the first grid inside the feed pipe 18 are continuously aligned and staggered to complete the gap discharge. It is worth noting that the grid holes on the first grid and the second grid 19 should be set larger to prevent blockage.

[0029] An insulation cover 12 is provided on the outer wall of the drying cylinder 1, and a waste heat chamber 16 is provided between the insulation cover 12 and the drying cylinder 1. A plurality of air outlet holes 13 connected to the waste heat chamber 16 are provided on the top side wall of the drying cylinder 1. A plurality of water collecting boxes 15 are provided on one side of the drying cylinder 1. Each water collecting box 15 is connected to the waste heat chamber 16 by a water outlet pipe 14. A plurality of heat absorbing plates are provided on the inner wall of the insulation cover 12.

[0030] After entering the drying drum 1 through the diversion holes, the hot air carries away water vapor and enters the waste heat chamber 16 through the air outlet 13. The heat is recovered by the heat absorbing plate, which insulates the outer wall of the drying drum 1 and saves energy. The condensed water droplets gather together and are then directed through the outlet pipe 14 to the water collection tank 15. Water collection tank 15 can be equipped with some water filtering components to facilitate water recovery.

[0031] The heat absorbing plate is an ordinary metal plate that can conduct heat. The heat absorbing plate blocks the wind speed, thereby increasing the retention time of water vapor inside the waste heat chamber 16 and improving the heat recovery effect.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
