Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Please refer to Figure 4 And Figure 5 The utility model provides a kind of technical scheme: a phosphate drying machine that is heated evenly, including box body 1, box body 1 is provided with stirring box 2, the bottom of stirring box 2 is connected with spring 11, the other end of spring 11 is connected with filter screen 9, box body 1 is further provided with motor 201, the driving end of motor 201 is connected with stirring rod 202, stirring rod 202 is arranged in stirring box 2, the other end of stirring rod 202 is rotatably connected in stirring box 2, the outer wall of stirring rod 202 is connected with multiple groups of stirring blade 203, one group of stirring blade 203 is connected with abutment 204 away from the one end of stirring rod 202, the bottom surface of abutment 204 is in abutment with filter screen 9, the top surface of box body 1 is welded with feed inlet 3, one end of feed inlet 3 extends into box body 1 through the outer wall of box body 1, the bottom surface of feed inlet 3 is connected with the top surface of stirring box 2, the bottom surface of feed inlet 3 is further provided with cover plate, cover plate is connected with feed inlet 3 by hinge, prevent material from spilling out of feed inlet 3, the outer wall of box body 1 is connected with placing plate 8, motor 201 is connected with placing plate 8.

[0025] In actual implementation, the material is poured into the feeding port 3 and then enters the stirring box 2. Then the motor 201 is started to drive the stirring rod 202 to rotate. Since the stirring blades 203 are arranged on the stirring rod 202, the stirring blades 203 rotate in the stirring box 2 at this time to scatter the material in the stirring box 2. Since one end of one group of the stirring blades 203 is connected with the abutting block 204 and the abutting block 204 abuts against the filter screen 9, when the stirring rod 202 continuously rotates, the abutting block 204 collides with the filter screen 9 once every rotation of the stirring rod 202, so that the filter screen 9 vibrates, preventing the material in the stirring box 2 from being partially accumulated on the filter screen 9 and clogging the pores of the filter screen 9, thus affecting the discharging and improving the work efficiency and reducing the economic cost.

[0026] Referring to Figure 1 As shown, the box body 1 is connected with the connecting box 4, the connecting box 4 is internally installed with the hot air furnace 401, the air outlet of the hot air furnace 401 is connected with the air inlet pipe 402, the other end of the air inlet pipe 402 is connected with the ventilation pipeline 403, the ventilation pipeline 403 is provided with the ventilation holes 404, the number of the ventilation holes 404 is multiple and they are uniformly arranged on the ventilation pipeline 403, the ventilation pipeline 403 is arranged in the box body 1 in an “S” shape, and the other end of the ventilation pipeline 403 is connected with the bottom surface of the filter screen 9.

[0027] In actual implementation, the hot air furnace 401 is started to make the hot air enter the ventilation pipeline 403 through the air inlet pipe 402. Since the ventilation pipeline 403 is provided with multiple ventilation holes 404, the hot air enters the box body 1 through the pipeline, and the ventilation pipeline 403 is in an “S” shape, so that the hot air is uniformly distributed in the box body 1, the material is dried uniformly to a large extent, the work efficiency of the device is improved, and meanwhile, one end of the ventilation pipeline 403 is connected with the bottom surface of the filter screen 9, so that the material is further prevented from being accumulated on the filter screen 9 and the preliminary drying degree of the material is improved.

[0028] It is worth mentioning that the joints of the ventilation pipeline 403 are all threadedly connected, so that the ventilation pipeline 403 can be easily disassembled and cleaned.

[0029] Referring to Figure 3 The top surface of the stirring box 2 is provided with the temperature control plate 10. After the material is poured into the stirring box 2, the temperature control plate 10 is started to preliminarily dry the material in the stirring box 2. The box body 1 is externally provided with the control system which is electrically connected with the temperature control plate 10. Since this is prior art, no more description is made in the specification and is not shown in the figure.

[0030] Referring to Figure 1The bottom of the box 1 is provided with two inclined surfaces 5 symmetrically arranged in the box 1. When the phosphates in the box 1 undergo the drying process, whether they naturally slide under the action of gravity or are displaced under the action of the hot air flow and the stirring device, the inclined surfaces 5 can guide the material to flow in a specific direction in an orderly manner, so that the dried material falls out along the inclined surfaces 5, facilitating subsequent collection by the staff and cleaning of the box 1.

[0031] It should be noted that the bottom surface of the box 1 is provided with a material collecting device, which is a prior art and will not be described in detail in this specification. The figure also does not show it.

[0032] Referring to Figure 1 and Figure 2 The top surface of the box 1 is connected to a pressure stabilizing pipe 7, the bottom end of which penetrates the outer wall of the box 1 and extends into the box 1. A filter plate is installed in the pressure stabilizing pipe 7, which provides a passage for airflow in the box 1, stabilizes the air pressure in the box 1, avoids accidents, improves the safety of the device, and prevents material from being blown out of the box 1 due to the hot air inside.

[0033] Referring to Figure 1 The bottom surface of the box 1 is connected to a foot 6, which keeps the box 1 at a certain distance from the ground during operation, facilitating ventilation and heat dissipation at the bottom of the equipment.

[0034] Working principle: The material is poured into the feeding port 3 and enters the stirring box 2 along the feeding port 3. Then the motor 201 is started to rotate the stirring rod 202. Since the stirring blades 203 are arranged on the stirring rod 202, the stirring blades 203 rotate in the stirring box 2 at this time, dispersing the material in the stirring box 2. Since one end of one group of stirring blades 203 is connected to a stop block 204, and the stop block 204 abuts against the filter screen 9, when the stirring rod 202 continuously rotates, the stop block 204 collides with the filter screen 9 once every revolution of the stirring rod 202, causing the filter screen 9 to vibrate. This prevents the material in the stirring box 2 from partially accumulating on the filter screen 9 and clogging the pores of the filter screen 9, affecting the discharge and improving the work efficiency and reducing the economic cost. After the material is put into the stirring box 2, the temperature control plate 10 is started to preliminarily dry the material. Then the hot blast stove 401 is started to make the hot air enter the ventilation duct 403 through the air inlet pipe 402. Since multiple ventilation ducts 403 are provided on the ventilation duct 403, the hot air enters the box 1 through the ducts, and the ventilation duct 403 is in the shape of "S", which can make the hot air evenly distributed in the box 1, greatly improving the uniformity of material drying and the work efficiency of the device. At the same time, one end of the ventilation duct 403 is connected to the bottom surface of the filter screen 9, further preventing the material from accumulating on the filter screen 9 and improving the preliminary drying degree of the material.
