DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] Reference Figure 1-12A dust removal and drying integrated system for carbendazim production includes a dryer shell 1, a feeding port 101 is provided at the top of the dryer shell 1, a plurality of feeding ports 101 are provided, and are annularly distributed near the edge of the top of the dryer shell 1, wet materials are added to the inside of the dryer shell 1 through the feeding port 101, and multiple feeding ports 101 are used for adding, which can increase the uniformity of material distribution and reduce the situation of pile-up. A discharge port 102 is provided at the bottom of the dryer shell 1, a first vertical pipe 3 is rotatably installed in the dryer shell 1, and the top of the first vertical pipe 3 extends to the outside of the dryer shell 1 and is connected to an air inlet pipe 103 through a rotary joint 302, and the dryer An air outlet pipe 104 is connected to the side wall of the dryer shell 1, and a filter 105 is installed at a position inside the dryer shell 1 corresponding to the air outlet pipe 104. An air outlet 303 is provided on the outside of the first vertical pipe 3, and an intermittent feeding mechanism 2 is provided inside the dryer shell 1. The wet material is blocked by the intermittent feeding mechanism 2 and dispersedly falls intermittently. The hot air enters the first vertical pipe 3 through the air inlet pipe 103 and is dispersedly discharged through the air outlet 303 to dry the intermittently falling material, and is filtered and dust-removed by the filter 105 and then discharged from the air outlet pipe 104. The finished product after drying falls to the bottom of the dryer shell 1, and the finished product can be discharged by opening the ball valve on the discharge port 102.

[0040] There are multiple intermittent blanking mechanisms 2, and the air outlets 303 are distributed outside the first vertical pipe 3 and below each intermittent blanking mechanism. There are also multiple air outlet pipes 104, and the positions of the air outlet pipes 104 correspond to the air outlets 303.

[0041] During the falling process of the material, it is blocked multiple times by the intermittent dropping mechanism 2 and is scattered intermittently, which can effectively increase the time the material stays inside the dryer shell 1 and the contact time between the material and the hot air during the falling process, thereby improving the drying effect.

[0042] In order to drive the first vertical pipe 3 to rotate, a first bevel gear 301 is fixed to the outside of the first vertical pipe 3, a rotating motor 5 is fixed to the top of the dryer housing 1, and a second bevel gear 501 is fixed to the output shaft of the rotating motor 5. The first bevel gear 301 is meshed with the second bevel gear 501. When the rotating motor 5 is turned on, the second bevel gear 501 can be driven to rotate, and then the first vertical pipe 3 is driven to rotate through the meshing of the first bevel gear 301 and the second bevel gear 501.

[0043] Among them, a cleaning brush 304 is fixed to the outside of the first vertical pipe 3, and the height of the cleaning brush 304 corresponds to the filter 105. The cleaning brush 304 can contact the filter 105 when rotating with the first vertical pipe 3. When the first vertical pipe 3 rotates, it can continuously drive the cleaning brush 304 to rotate with it. The cleaning brush 304 will contact the filter 105 once every rotation, so that the filter 105 can be cleaned, the dust particles covering the filter 105 can be cleared, and the smoothness of the filter 105 can be ensured.

[0044] Example 2

[0045] Reference Figure 1-12 The difference between this embodiment and embodiment 1 is that a blocking ring 106 is provided between adjacent material-resting and falling mechanisms, the top of the blocking ring 106 is an inclined surface, and the top diameter of the blocking ring 106 is larger than the bottom diameter, and the upper surface of the blocking ring 106 is provided with a plurality of equally spaced annular ridges, and the material falling from the material-resting and falling mechanism is blown around by the hot air blown out of the air outlet 303, and will fall on the blocking ring 106 and slowly slide down along the blocking ring 106, and the annular ridges can further play a blocking role, and can further increase the sliding speed and improve the drying effect, and a vibration motor can be installed on the outer wall of the dryer housing 1 to drive the continuous vibration of the whole, thereby promoting the downward movement of the material.

[0046] Example 3

[0047] Reference Figure 1-12 The difference between this embodiment and embodiment 2 is that the blanking mechanism includes a fixed bracket 201 and a lifting drive mechanism, the fixed bracket 201 is provided with a plurality of blanking notches, a fan-shaped blocking plate 202 is provided in the blanking notches, the fixed bracket 201 and the plurality of fan-shaped blocking plates 202 form a boss shape, the fixed bracket 201 is fixed to the inner wall of the dryer housing 1, and the lifting drive mechanism drives the fan-shaped blocking plate 202 to rise and fall;

[0048] As the fan-shaped sealing plate 202 rises and falls rapidly, the gap between the fan-shaped sealing plate 202 and the fixed bracket 201 will continue to increase and decrease, so that the material will intermittently fall from the gap to achieve the effect of dispersing the material. Since the falling material has a greater degree of dispersion, it can contact the hot air more evenly to exchange heat, thereby improving the drying effect.

[0049] In order to drive the fan-shaped blocking plate 202 to rise and fall quickly, the lifting drive mechanism includes a first lifting ring 203, the fan-shaped blocking plate 202 is fixed around the first lifting ring 203 through a connecting bracket 205, and a first limiting rod 204 is fixed on the inner wall of the first lifting ring 203, a reciprocating guide groove 305 is opened on the outside of the first vertical pipe 3, one end of the first limiting rod 204 extends into the reciprocating guide groove 305, a plurality of vertical guide rods 206 are fixed to the top of the first lifting ring 203, the top of the vertical guide rod 206 movably passes through the fixed bracket 201 and extends to the top of the fixed bracket 201, and a second lifting ring 207 is fixed between the tops of the plurality of vertical guide rods 206;

[0050] As the first vertical tube 3 rotates, the first limiting rod 204 rotates along with the first vertical tube 3. Since the first limiting rod 204 is stuck in the reciprocating guide groove 305 and cooperates with the vertical guide limiting function of the vertical guide rod 206, it can quickly drive the fan-shaped sealing plate 202 to continuously reciprocate and rise and fall, thereby achieving the purpose of intermittent material dropping.

[0051] Example 4

[0052] Reference Figure 1-12 , the difference between this embodiment and embodiment 3 is that a plurality of transmission devices 4 are fixed to the top of the fixed bracket 201, a second vertical pipe 401 is rotatably installed inside the transmission device 4, a dredge 402 is rotatably installed on one side of the transmission device 4, the inclination angle of the dredge 402 is consistent with that of the fixed bracket 201, a U-shaped transmission rod 208 is fixed to the top of the second lifting ring 207 and the corresponding position of the second vertical pipe 401, one end of the U-shaped transmission rod 208 away from the second lifting ring 207 is vertically downward and movably extended into the second vertical pipe 401, a spiral opening 405 is opened on the second vertical pipe 401, a second limiting rod 209 is fixed to the outside of the U-shaped transmission rod 208, and the second limiting rod 209 extends to the outside of the second vertical pipe 401 through the spiral opening 405, a third bevel gear 403 is fixed to the dredge 402, a fourth bevel gear 404 is fixed to the second vertical pipe 401, and the third bevel gear 403 is meshed with the fourth bevel gear 404;

[0053] As the second lifting ring 207 is continuously lifted and lowered, the U-shaped transmission rod 208 is continuously lifted and lowered, thereby driving the second limiting rod 209 to continuously lift and move in the second vertical tube 401. Since the second limiting rod 209 is stuck in the spiral opening 405, the second vertical tube 401 is continuously rotated while continuously lifting and moving. The rotation direction of the second vertical tube 401 changes with the movement direction of the second limiting rod 209. Since the third bevel gear 403 is meshed with the fourth bevel gear 404, the clearing device 402 can be driven to continuously rotate. The clearing device 402 can improve the fluidity of the material by stirring, thereby promoting the material to fall from the gap.
