DETAILED DESCRIPTION
[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0024] See also Figures 1 to 3 As shown, a drying device includes a heating cylinder 1, a mixing cylinder 2, a feeding assembly 3, a first bellows 4, a second bellows 5, an exhaust pipe 7, a cooling box 6, and a drain pipe 8. The heating cylinder 1 is an internal hollow cylinder, and a leg 18 is provided at the bottom of the heating cylinder 1. The feeding assembly 3 is fixedly mounted at one end of the heating cylinder 1, and a cylinder cover 11 is rotatably connected to the other side of the heating cylinder 1 for opening or closing the heating cylinder 1. The mixing cylinder 2 is rotatably connected to the inside of the heating cylinder 1, and a stirring plate 21 is provided inside the mixing cylinder 2 for stirring the raw materials to be heated so that the raw materials are heated more evenly. The central axis of the mixing cylinder 2 is colinear with the central axis of the heating cylinder 1. In this embodiment, a heating plate 13 and a plurality of supporting rollers 12 for supporting the mixing cylinder 2 and rotating the mixing cylinder 2 along its own axis are fixedly mounted on the inner wall of the heating cylinder 1, wherein the supporting rollers include a supporting block and a universal ball rotatably connected to one end of the supporting block, and the universal ball abuts against the outer wall of the mixing cylinder 2. A driving rod 14 is rotatably connected inside the heating cylinder 1 and located between the heating cylinder 1 and the mixing cylinder 2. The axial direction of the driving rod 14 is parallel to the axial direction of the heating cylinder 1. A second gear 15 is fixedly sleeved on the outer wall of the driving rod 14. A gear ring 16 meshing with the second gear 15 is fixedly sleeved on the outer wall of the mixing cylinder 2. A power unit 17 for rotating the driving rod 14 is provided at one end of the heating cylinder 1.
[0025] Preferably, there are multiple second gears 15, and the multiple second gears 15 are arranged on the driving rod 14 at intervals along the axial direction of the driving rod 14. There are multiple gear rings 16, and the multiple gear rings 16 correspond to the multiple second gears 15 one by one and mesh with each other, so that the mixing drum 2 rotates more smoothly. In this embodiment, the power unit 17 includes a second motor 171 fixedly arranged at one end of the heating drum 1, and the output end of the second motor 171 is fixedly sleeved with a first rotating wheel 172, and the end of the driving rod 14 close to the second motor 171 passes through the side wall of the heating drum 1 and is fixedly sleeved with a second rotating wheel 173, and the first rotating wheel 172 and the second rotating wheel 173 are connected by a belt 174.
[0026] During implementation, the raw materials are put into the mixing drum 2 through the feeding assembly 3, the heating plate 13 is started to heat the mixing drum 2, and the second motor 171 is started at the same time. The output end of the second motor 171 drives the first wheel 172 to rotate, and the first wheel 172 drives the second wheel 173 to rotate through the belt 174, thereby driving the driving rod 14 to rotate and the second gear 15 on the driving rod 14 to rotate. Since the second gear 15 is meshed with the gear ring 16, the second gear 15 can drive the mixing drum 2 to rotate. During the mixing process, the raw materials are heated more evenly through the stirring plate 21.
[0027] The feed assembly 3 is used to grind the raw materials, and includes a cover body 31 covered at one end of the heating cylinder 1, and a feed port 32 opened at the top of the cover body 31. Two grinding rollers 33 are rotatably connected in the feed port 32. The axial directions of the two grinding rollers 33 are perpendicular to the feeding direction of the feed port 32, and a gap is provided between the two grinding rollers 33 for the material to pass through. One end of the axial direction of the two grinding rollers 33 passes through the side wall of the feed port 32 and is respectively fixedly sleeved with a first gear 34. The two first gears 34 are meshed with each other. A first motor 35 for driving any one of the grinding rollers 33 to rotate is fixed on the side of the feed port 32 away from the first gear 34. During implementation, the staff puts the raw materials into the feed port 32, and then starts the first motor 35, which rotates, and the two grinding rollers 33 are rotated through the two meshing first gears 34 to grind the agglomerated raw materials to avoid insufficient drying caused by direct drying of the raw materials in the agglomerated state.
[0028] The first bellows 4 is connected and arranged on the outside of the feeding assembly 3, and the second bellows 5 is connected and arranged on the side of the heating cylinder 1 close to the cylinder cover 11, and is located above the cylinder cover 11, that is, the first bellows 4 and the second bellows 5 are respectively located at the two ends of the heating cylinder 1, and a cooling box 6 is fixed on one side of the heating cylinder 1, and the cooling box 6 is used to cool the exhaust pipe 7. One end of the exhaust pipe 7 is connected with the second bellows 5, and the free end of the exhaust pipe 7 continues to extend and connects with the first bellows 4 after passing through the cooling box 6, wherein the bottom of the exhaust pipe 7 is also connected and connected with a drain pipe 8. In this embodiment, the first bellows 4 and the second bellows 5 both include a box body and a fan arranged in the box body, and the exhaust directions of the two fans are the same, which are used to make the hot air circulate quickly to enhance the drying effect.
[0029] In this embodiment, the cooling box 6 includes a hollow box body 61, the box body 61 is filled with coolant, and the bottom of the box body 61 is provided with a liquid inlet pipe 62 and a liquid outlet pipe 63 for providing coolant to the inside of the box body 61, which is used to replace the coolant or circulate the coolant through the liquid inlet pipe 62 and the liquid outlet pipe 63 to dissipate heat. The coolant can be a liquid with a heat exchange effect in the prior art, which is used to absorb the temperature of the exhaust pipe 7 and quickly cool the inner wall of the exhaust pipe 7. It will not be repeated here.
[0030] During the implementation, the staff starts the first bellows 4 and the second bellows 5, that is, starts the two fans during the heating and stirring of the raw materials. At this time, the fan of the first bellows 4 blows air into the mixing drum 2. At the same time, the fan of the first bellows 4 can also blow the raw materials dropped from the feeding assembly 3 into the mixing drum, so that the raw materials are heated more evenly. The fan of the second bellows 5 extracts the high-temperature and high-humidity gas in the mixing drum 2 and discharges it into the first bellows 4 through the exhaust pipe 7, so that the high-temperature gas in the mixing drum 2 forms a cycle. When the high-temperature and high-humidity gas passes through the cooling box 6 through which the exhaust pipe 7 passes, the coolant in the cooling box 6 cools the exhaust pipe. According to the principle that water vapor will condense into water when it is cooled, in the process of cooling the exhaust pipe 7 by the cooling box 6, the water vapor in the high-humidity gas in the exhaust pipe 7 will be pre-cooled and condensed into water, and discharged through the drain pipe 8. Then, the gas passing through the cooling box 6 will change from high-temperature and high-humidity gas to dry gas. It should be noted that the high-temperature and high-humidity gas that has passed through the cooling box 6 will still carry a certain amount of heat, that is, the cooling box 6 will not directly reduce the high-temperature and high-humidity gas to cold air. The wind blown back through the exhaust duct 7 and the first wind box 4 fan still has a certain temperature, which can reduce the heating power of the heating plate 13 and achieve the purpose of energy saving.
[0031] Preferably, the horizontal height of one end of the exhaust pipe 7 close to the second wind box 5 is higher than the horizontal height of one end of the exhaust pipe 7 close to the first wind box 4, wherein the cooling box 6 is located on the side close to the second wind box 5, and the drain pipe 8 is located on the side close to the first wind box 4. That is, the exhaust pipe 7 is an inclined pipe inclined from the second wind box 5 to the first wind box 4 from top to bottom. By arranging the exhaust pipe 7 obliquely, the high-temperature and high-humidity gas in the exhaust pipe 7 passes through the cooling box 6. When the moisture therein condenses into water, the condensed water in the exhaust pipe 7 is conveniently discharged along the inner wall of the exhaust pipe 7 to the drain pipe 8 due to the inclined arrangement of the exhaust pipe 7. Furthermore, a U-shaped drain bend 71 is provided on the exhaust pipe 7 between the first wind box 4 and the second wind box 5, and the drain pipe 8 is arranged at the bottom of the drain bend 71 to further facilitate drainage.
[0032] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
