It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0014] like Figure 1-2 As shown, the present invention provides a powdered ammonium phosphate drying device, including a drying box 100, a stirring component 200 and an air supply component 300. During implementation, the air supply component 300 supplies hot air to the drying box 100, and the hot air blows toward the stirring component 200, the stirring assembly 200 is driven to rotate. During the process of drying the powdered ammonium phosphate in the drying box 100 by the hot air, the stirring assembly 200 rotates to realize the stirring treatment for the powdered ammonium phosphate, so that the drying effect is better.
[0015] The top of the drying box 100 in this embodiment is provided with a feeding port 121 , and the powdered ammonium phosphate enters the drying box 100 from the feeding port 121 .
[0016] The drying box 100 includes a box body 110 and a box cover 120. The box cover 120 is covered on the box body 110. One end of the rotating shaft 220 is connected to the box cover 120 through a bearing. The box cover 120 is provided with a feeding port 121. The structure is convenient for the installation of the stirring assembly 200 and the cleaning work. The connection between the box body 110 and the box cover 120 can be connected by screws or snaps, which are not limited to facilitate disassembly, and facilitate cleaning and maintenance.
[0017] like figure 2 As shown, the stirring assembly 200 in this embodiment includes a fixed plate 210, a rotating shaft 220 and a stirring wheel 230. The fixed plate 210 is built in the drying box 100, one end of the rotating shaft 220 is rotatably connected to the drying box 100, and the other end of the rotating shaft 220 is connected to the drying box 100. The fixed plate 210 is rotatably connected. The stirring wheel 230 includes a cylindrical body 231 and a plurality of blades 232. The cylindrical body 231 is sleeved on the rotating shaft 220. The plurality of blades 232 are evenly arranged along the circumference of the cylindrical body 231. A discharge port 211 is opened on the fixing plate 210 .
[0018] The fixing plate 210 is fixed on the inner wall of the drying box 100 by screws, and the fixing plate 210 plays the role of fixing the rotating shaft 220. At the same time, the materials are accumulated on the fixing plate 210. Under the movement of the stirring wheel 230, the stirring effect of the materials is realized. At the same time, the fixed plate 210 is provided with a discharge port 211. The size of the discharge port 211 is smaller than the distance between the two adjacent blades 232. During the rotation of the blades 232, the blades 232 remove the powdered ammonium phosphate from the discharge port. The material port 211 is scraped out.
[0019] Wherein, one end of the rotating shaft 220 is rotatably connected with the bearing installed on the fixing plate 210 .
[0020] Preferably, the stirring assembly 200 further includes a rotating plate 240. The rotating plate 240 is fixedly connected with the rotating shaft 220. The rotating plate 240 is located on the side of the fixed plate 210 away from the stirring wheel 230. The rotating plate 240 rotates with the rotating shaft 220 and is connected to the fixed plate. 210 slides against each other, and the rotating plate 240 blocks the discharge port 211 intermittently.
[0021] Specifically, as Image 6 As shown, the rotating plate 240 includes a circular ring 241, a plurality of connecting rods 242 and a plurality of baffles 243. The circular ring 241 is sleeved on the rotating rod, and the plurality of connecting rods 242 are in one-to-one correspondence with the plurality of baffles 243. Each One end of the connecting rod 242 is connected to the ring 241, and the other end of each connecting rod 242 is connected to the corresponding baffle plate 243. During the rotation process of the plurality of baffle plates 243, the discharge ports 211 are alternately blocked, and baffle plates are provided. The more the number of 243, the longer the powdered ammonium phosphate stays above the fixed plate 210, and the longer the drying time, so the drying time can be controlled by controlling the number of baffles 243, but the number of baffles is not the longer. As many as possible, and adjust and set according to actual needs.
[0022] preferably, as Figure 5 As shown, the rotating plate 240 is fixed on the rotating shaft 220 by a fixing screw 250, a through hole is formed on the rotating plate 240, one end of the rotating shaft 220 passes through the through hole, one end of the fixing screw 250 is threadedly connected with the rotating shaft 220, and one end of the rotating plate 240 is threaded. The other side of the rotating plate 240 is in contact with the step on the rotating shaft 220, and the other side of the rotating plate 240 is in contact with the fixing screw 250. Of course, other connection methods can also be used, which are not limited.
[0023] Preferably, the blade 232 is made of a material with good thermal conductivity and light weight, which is convenient for the heat transfer of the blade 232 and the rotation of the blade 232. The hot air blows on the blade 232 to heat the blade 232, and the heated blade 232 can be used for powdery contact with the blade 232. ammonium phosphate is heated.
[0024] preferably, as Figure 4 As shown, an air guide groove 233 is provided on the side of the blade 232 facing the hot air outlet of the air supply assembly 300. The length direction of the air guide groove 233 is the same as the length direction of the blade 232, so that the wind blowing on the blade 232 flows along the blade. 232 moves in the height direction, because the blades 232 are arranged in a spiral shape, in this embodiment, the pitch of the blades 232 is 8m, the pitch of the blades 232 is 1m, and the angle between two adjacent blades 232 is 15 degrees, Of course, other size designs can also be used, which is convenient for blowing the blades 232 , and most of the wind moves downward along the blades 232 .
[0025] Specifically, the vertical distance from each blade 232 to the hot air outlet of the air supply assembly 300 increases sequentially from top to bottom. Under the action of the hot air, the powdered ammonium phosphate sticks to the surface of the blade 232 and moves downward. Since the wetness of the powdered ammonium phosphate gradually decreases from top to bottom, the The wind force is gradually reduced, and while maintaining effective drying, the resistance to the falling process of the powdered ammonium phosphate is reduced, and the time required for the powdered ammonium phosphate to fall on the fixed plate 210 is shortened.
[0026] In this embodiment, the hot air port of the air supply assembly 300 is communicated with the drying box 100, such as image 3 As shown, the direction of the hot air of the air supply assembly 300 is directed to the blades 232 along the tangential direction of the cylinder 231 , and the hot air port is located just below the feed port 121 .
[0027] Preferably, the air supply assembly 300 includes a support plate 310, a fan 320, an air inlet pipe 330, an air outlet pipe 340, a heater 350 and an exhaust pipe 360. The support plate 310 is fixed on the side wall of the drying box 100, and the fan 320 is fixed On the support plate 310, one end of the air inlet pipe 330 is communicated with the air inlet of the fan 320, one end of the air outlet pipe 340 is communicated with the air outlet of the fan 320, and the other end of the air outlet pipe 340 is communicated with the interior of the drying box 100, The heater 350 is installed on the air inlet pipe 330 and is directed to the blade 232 along the tangential direction of the cylinder 231 , and one end of the exhaust pipe 360 is communicated with the interior of the drying box 100 .
[0028] More preferably, as image 3 As shown, a nozzle 342 is installed on the end of the air outlet duct 340 away from the fan 320, and a booster pump 341 is installed on the air outlet duct 340. The nozzle 342 is conducive to the concentrated wind blowing the blades 232. 341 is pressurized to increase the wind force. It is understandable that the speed of the wind does not need to be too high, and the stirring wheel 230 can be slowly pushed to rotate.
[0029] More preferably, the number of the air outlet pipes 340 is multiple, the plurality of air outlet pipes 340 are arranged in parallel along the length direction of the cylinder 231, and one end of the plurality of air outlet pipes 340 is connected with the air outlet of the fan 320, and the plurality of air outlet pipes 340 are connected with each other. The other ends of the pipes 340 are both communicated with the interior of the drying box 100 and are directed to positions of different heights of the blades 232 along the tangential direction of the cylinder body 231 .
[0030] More preferably, filters 361 are installed on both the intake pipe and the exhaust pipe 360. The filter screen 361 on the intake pipe can prevent the hot air entering the box 110 from containing impurities, and the filter screen 361 on the exhaust pipe 360 can prevent the hot air from entering the box 110. The powdered ammonium phosphate in the body 110 escapes.
[0031] Wherein, the heater 350 can be a resistance wire heating tube, or other heating elements can be used to heat the air entering from the air inlet duct.
[0032]Workflow: It should be noted that this drying device is different from the traditional drying method. The traditional drying method is to put the material into the drying device first, and then dry it by stirring and blowing hot air. Stirring and drying are carried out simultaneously. Specifically, the fan 320 and the heater 350 are turned on, and the heated air is blown into the box 110. Since the hot air is directed toward the blades 232 along the tangential direction of the cylinder 231, a cutting action is applied to the blades 232. The force drives the cylinder 231 to rotate, so that the entire stirring wheel 230 rotates. The rotation speed of the stirring wheel 230 is related to the wind speed in the air outlet pipe 340. The greater the wind speed in the air outlet pipe 340, the faster the rotation speed of the stirring wheel 230 On the contrary, the smaller the wind speed, the slower the rotation speed of the stirring wheel 230. The speed of the stirring wheel 230 in this embodiment adopts a low speed, that is, the stirring wheel 230 rotates slowly in the box 110, and the rotating speed used by the stirring wheel 230 Ensure that the heating effect is good at 10s/r. At this time, add the powdered ammonium phosphate that needs to be dried to the feeding port 121. Since the feeding port 121 is located directly above the hot air outlet, the powdered ammonium phosphate that falls into it Under the action of hot air, it sticks to the blade 232 and rolls down. Since the blade 232 is heated by contact with the hot air, with the rolling of the powdered ammonium phosphate, the hot air is in the process of drying the powdered ammonium phosphate. The rolling of ammonium, the heated blade 232 can heat and dry each side of the powdered ammonium phosphate, and achieve effective drying of the powdered ammonium phosphate until the powdered ammonium phosphate falls on the fixed plate 210, followed by the next blade 232. The ammonium phosphate on the fixed plate 210 will accumulate on the surface of the blade 232 facing the rotation direction, and push the powdered ammonium phosphate to rotate around the cylinder 231. At this time, the ammonium phosphate contacts the heated blade 232, Heat treatment is performed again until it runs out of the discharge port 211 .
[0033] By setting the air supply assembly 300, the hot air is blown into the drying box 100 to dry the powdered ammonium phosphate, and at the same time, it is blown to the stirring wheel 230, which drives the stirring wheel 230 to rotate. Below, when the powdered ammonium phosphate enters the drying box 100, under the action of hot air, it rolls along the spiral surface of the blade 232 until it falls on the fixed plate 210, and the other side of the blade 232 pushes the ammonium phosphate on the fixed plate 210 to continue. It moves until it falls from the discharge port 211. At the same time, the blade 232 is heated by hot air, and the heat emitted by the blade 232 continues to heat and dry the surrounding ammonium phosphate. The device only needs to provide hot air to achieve efficient drying of powdered ammonium phosphate. , low cost, and powerful drying function.
