[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0018] See also Figure 1-3 In this embodiment, a drying device for nano pigment production includes a containing mechanism, a transport mechanism is arranged inside the containing mechanism, and a heating mechanism is arranged inside the containing mechanism.

[0019] The transport mechanism includes a drying bin 8, a screw shaft 11, a discharge pipe 15 and a drive assembly 16. The drying bin 8 is fixedly installed inside the accommodating mechanism. There are two screw shafts 11, which are rotatably installed inside the accommodating mechanism. The screw shafts 11 are located inside the drying bin 8. A second partition 12 is fixedly installed on the inner bottom wall of the drying bin 8 and between the screw shafts 11. The discharge pipe 15 is fixed and connected to the left side of the accommodating mechanism. The discharge pipe 15 is located inside the drying bin 8. The screw shaft 11 penetrates and extends to the right side of the accommodating mechanism. The drive assembly 16 is fixedly installed on the right side of the accommodating mechanism, and the drive assembly 16 is arranged outside the entire screw shaft 11.

[0020] Among them, the right side of the second partition 12 is not fixedly connected to the left side of the inner wall of the containing mechanism, so that the second partition 12 divides the internal space of the drying bin 8 into two. When the driving component 16 drives the spiral shaft 11 to move, the nano-pigment inside the space of the front drying bin 8 can enter the space inside the rear front drying bin 8 through the gap between the second partition 12 and the containing mechanism, thereby realizing long-term drying treatment of the nano-pigment. At the same time, the overall footprint of the device is shortened and the space utilization rate is improved.

[0021] It should be noted that the driving assembly 16 includes a reduction motor, a protective shell and two gears. The two gears are fixedly mounted on the outside of the screw shaft 11 and mesh with each other. The reduction motor is fixedly mounted on the left side of the accommodating mechanism, and its output end is fixedly connected to the front screw shaft 11, so that after the front screw shaft 11 rotates, the rear screw shaft 11 rotates in the opposite direction.

[0022] Specifically, after the wet nano-pigment is fed into the containing mechanism, the driving assembly 16 starts the front spiral shaft 11 and drives the rear spiral shaft 11 to rotate in the opposite direction, so that the device extends the heating distance of the heating mechanism for the nano-pigment, but effectively shortens the length of the device, thereby improving the space utilization rate of the device. At the same time, in cooperation with the heating mechanism, the nano-pigment can be quickly and evenly dried, which simplifies the operation and reduces the cost of introducing highly technical personnel.

[0023] In this embodiment, the accommodating mechanism includes a carrying bin 1, a top cover 2 is detachably installed on the top of the carrying bin 1, a maintenance door 3 is embedded in the front of the carrying bin 1, a first partition 4 is fixedly installed inside the carrying bin 1, a feed hopper 10 with one end passing through and extending to the bottom of the top cover 2 is fixedly installed on the top of the top cover 2, the feed hopper 10 is located on the rear side of the second partition 12, a drying bin 8 is fixedly installed inside the carrying bin 1 and is located above the first partition 4, a spiral shaft 11 is rotatably connected to the carrying bin 1 through a bearing, a discharge pipe 15 is connected to the left side of the carrying bin 1 and is located on the front side of the second partition 12, and heat dissipation holes are opened on the back of the carrying bin 1 and below the first partition 4.

[0024] Among them, the provision of the maintenance door 3 allows for convenient maintenance of the mechanism inside the accommodating mechanism, and the provision of the first partition 4 prevents the heat dissipation holes from affecting the operation of the mechanism above the first partition 4 .

[0025] It should be noted that the top cover 2 is detachably mounted to the bearing chamber 1 by means of bolts, which facilitates maintenance when a failure occurs in the internal mechanism of the accommodating mechanism and also facilitates the maintenance of the entire device.

[0026] In this embodiment, the heating mechanism includes a hot air blower 5, a connecting pipe 7, a heating rod group 9, an infrared heater 13 and a protective mesh cover 14. The hot air blower 5 is fixedly installed on the inner bottom wall of the carrying bin 1, and the air outlet of the hot air blower 5 is connected to the transport pipe 6, which passes through the carrying bin 1 and extends to the top of the top cover 2. The connecting pipe 7 is fixedly installed on the top of the top cover 2, and the connecting pipe 7 passes through and extends to the bottom of the top cover 2. The heating rod group 9 is fixedly installed on the outside of the drying bin 8. There are four infrared heaters 13, and the infrared heaters 13 are fixedly installed on the bottom of the top cover 2. The infrared heaters 13 are evenly distributed on the front and rear sides of the second partition 12. There are two protective mesh covers 14, and the protective mesh covers 14 are respectively fixedly installed on the outside of the front and rear infrared heaters 13 as a whole. The connecting pipe 7 is located inside the rear protective mesh cover 14, and the rear protective mesh cover 14 is located on the right side of the feed hopper 10. An exhaust pipe with one end passing through and extending to the bottom of the top cover 2 is fixedly installed on the top of the top cover 2 and located on the front side of the second partition 12, and the exhaust pipe is located inside the front protective mesh cover 14.

[0027] The first partition plate 4 effectively prevents the hot air blower 5 from being affected by the heating rod group 9 .

[0028] It should be noted that the provision of the protective mesh cover 14 prevents the drying of the nano pigment from affecting the operation of the infrared heater 13, the connecting pipe 7 and the exhaust pipe, and also avoids the waste of the nano pigment.

[0029] Specifically, the wet nano-pigment is introduced into the interior of the drying bin 8 through the feed hopper 10, and the driving component 16 is started to drive the spiral shaft 11 to transport the nano-pigment. At this time, the hot air blower 5, the heating rod group 9 and the infrared heater 13 are started, so that the nano-pigment inside the drying bin 8 can be quickly and evenly heated and dried inside and outside during transportation, and discharged through the discharge pipe 15, so that the overall operation of the device is simple and the drying processing efficiency and effect are improved.
