Description

Technical Field

[0001] This utility model relates to the field of pyrfluthrin processing technology, and in particular to a high-efficiency drying device for pyrfluthrin production. Background Technology

[0002] In the production of pyrifluquinazon, the drying process is a crucial step in ensuring product quality and production efficiency. Traditional pyrifluquinazon drying equipment typically employs a static drying method. During the drying process, the material has poor fluidity, and hot air cannot fully contact the material, resulting in low drying efficiency, long drying time, and high energy consumption.

[0003] Existing drying equipment has a simple stirring structure, which cannot achieve all-round stirring of materials. This can easily lead to local over-drying or under-drying of materials, affecting the stability of product quality.

[0004] Some drying units require manual operation during material feeding and discharging, which not only increases labor intensity but also reduces production efficiency, making it difficult to meet the needs of large-scale industrial production. Therefore, developing a high-efficiency, energy-saving, and easy-to-operate pyrifluquinazon drying unit has become an urgent problem to be solved by the industry. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a high-efficiency drying device for the production of pyrfluthrin.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency drying device for the production of pyrifluquinazon includes a base and a drying tank. The two ends of the drying tank are rotatably mounted on a first support and a second support, respectively. A rotary motor is mounted on the second support, and the output shaft of the rotary motor is fixed to the drying tank. One side of the drying tank is provided with an inlet / outlet and an exhaust port. A filter is installed inside the exhaust port. An aeration and stirring shaft is rotatably mounted inside the drying tank. One end of the aeration and stirring shaft extends to the outside of the drying tank and is connected to a hot air inlet pipe through a rotary joint. Multiple first branch stirring shafts are rotatably mounted at equal intervals inside the drying tank. The interiors of the aeration and stirring shafts and the first branch stirring shafts are hollow and interconnected. Multiple exhaust holes are provided on the first branch stirring shafts.

[0008] Preferably, a first stirring blade is fixed to the outside of the first branch stirring shaft, and a first spur gear is fixed to the end of the first branch stirring shaft away from the stirring shaft. A first toothed ring is fixed to the inner wall of the drying tank, and the first spur gear meshes with the first toothed ring.

[0009] Preferably, a second stirring branch is rotatably installed on the inner wall of the drying tank, a second stirring blade is fixed to the outside of the second stirring branch, and a first bevel gear is fixed to one end of the second stirring branch near the ventilated stirring shaft, and a second bevel gear is fixed to the outside of the stirring shaft. The first bevel gear and the second bevel gear mesh with each other, and the first branch stirring shaft and the second stirring branch are arranged alternately in sequence.

[0010] Preferably, a first rotating shaft and a second rotating shaft are rotatably mounted on the top end of the first bracket, a second spur gear and a third spur gear are rotatably mounted on both ends of the first rotating shaft, and a fourth spur gear and a fifth spur gear are rotatably mounted on both ends of the second rotating shaft.

[0011] Preferably, a second toothed ring is fixed to the outside of the drying tank, a third toothed ring is fixed to the outside of the stirring shaft, a second spur gear meshes with the second toothed ring, a third spur gear meshes with a fourth spur gear, a fifth spur gear meshes with the third toothed ring, and the second, third, fourth, and fifth spur gears have the same diameter, as do the second and third toothed rings.

[0012] Preferably, the first bracket is hinged to the top of the base, and a hydraulic cylinder is provided between the second bracket and the base. The cylinder body of the hydraulic cylinder is hinged to the top of the base, and the output shaft of the hydraulic cylinder is hinged to the second bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This invention utilizes a rotary motor to drive the drying tank to rotate, which, in conjunction with the counter-rotation of the ventilated stirring shaft, achieves dual stirring of the material. The rotation of the drying tank causes the material to flow continuously due to gravity. The ventilated stirring shaft, along with its first and second branch stirring shafts, can stir the material in all directions, improving its flowability. Simultaneously, the exhaust holes on the first branch stirring shaft disperse hot air, significantly increasing the contact area and contact rate between the hot air and the material, thereby greatly improving drying efficiency and shortening drying time.

[0015] 2. The unique gear transmission structure allows the stirring shaft to rotate synchronously in the opposite direction relative to the drying tank through the meshing transmission between gears when the drying tank rotates. This eliminates the need for an additional device to drive the stirring shaft, reducing energy consumption and making the entire drying device more energy-efficient and environmentally friendly, thus lowering production costs.

[0016] 3. The first bracket is hinged to the base, and the second bracket is connected to the base through a hydraulic cylinder. By extending and retracting the hydraulic cylinder, the inlet and outlet side of the drying tank can be easily raised and lowered. It is raised when feeding and lowered when discharging, which greatly improves the feeding and discharging efficiency, reduces manual operation, reduces labor intensity, and meets the needs of large-scale industrial production.

[0017] 4. Comprehensive stirring and sufficient heat exchange prevent localized over- or under-drying of materials, ensuring uniform heating and drying, thereby guaranteeing the stability of pyrifluquinazon product quality and enhancing the product's market competitiveness.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example

[0030] Reference Figure 1-8 A high-efficiency drying device for the production of pyrifluquinazon includes a base 1 and a drying tank 2. The two ends of the drying tank 2 are rotatably mounted on a first support 3 and a second support 301, respectively. A rotary motor 302 is mounted on the second support 301. The output shaft of the rotary motor 302 is fixed to the drying tank 2. An inlet / outlet 201 and an exhaust port 202 are provided on one side of the drying tank 2. A filter is installed inside the exhaust port 202. An air-purifying stirring shaft 4 is rotatably mounted inside the drying tank 2. One end of the air-purifying stirring shaft 4 extends to the outside of the drying tank 2 and is connected to a hot air inlet pipe 501 through a rotary joint 5. Multiple first branch stirring shafts 401 are rotatably mounted at equal intervals inside the drying tank 2. The interiors of the air-purifying stirring shaft 4 and the first branch stirring shafts 401 are hollow and interconnected. Multiple exhaust holes 402 are provided on the first branch stirring shafts 401.

[0031] The drying tank 2 is rotated by the rotary motor 302, so that the inlet and outlet 201 face upwards. Wet material is added into the drying tank 2, and then the outlet 201 is sealed. Hot air is introduced into the drying tank 2 through the hot air inlet pipe 501 to dry the wet material. During the drying process, the drying tank 2 is continuously driven to rotate slowly. Under the action of gravity, the wet material is continuously flowed, which improves the drying effect. By driving the ventilation and stirring shaft 4 to rotate in the opposite direction to the drying tank 2, the wet material can be stirred, which further improves the fluidity of the wet material and the heat exchange effect between the hot air and the material. The exhaust hole 402 on the first branch stirring shaft 401 can disperse the hot air and increase the contact rate between the hot air and the material, which can effectively improve the drying efficiency.

[0032] The first branch stirring shaft 401 is fixed with a first stirring blade 403 on its outside, and a first spur gear 407 is fixed at the end of the first branch stirring shaft 401 away from the stirring shaft 4. A first toothed ring 204 is fixed on the inner wall of the drying tank 2, and the first spur gear 407 meshes with the first toothed ring 204.

[0033] When the stirring shaft 4 rotates relative to the drying tank 2, the first spur gear 407 will travel along the first gear ring 204, causing the stirring shaft 4 to rotate, thereby stirring the wet material through the first stirring blade 403, which can improve the stirring effect.

[0034] The drying tank 2 has a second stirring branch 404 rotatably mounted on its inner wall. The second stirring branch 404 has a second stirring blade 405 fixed to its outer side. The second stirring branch 404 has a first bevel gear 409 fixed to one end near the ventilated stirring shaft 4. The stirring shaft 4 has a second bevel gear 408 fixed to its outer side. The first bevel gear 409 and the second bevel gear 408 mesh with each other. The first branch stirring shaft 401 and the second stirring branch 404 are arranged alternately in sequence.

[0035] When the stirring shaft 4 rotates relative to the drying tank 2, the first bevel gear 409 moves along the second bevel gear 408. The meshing of the two drives the second stirring branch 404 to rotate, thereby stirring the wet material through the second stirring blade 405, which can improve the stirring effect.

[0036] The first support 3 has a first rotating shaft 303 and a second rotating shaft 306 rotatably mounted on its top end. The first rotating shaft 303 has a second spur gear 304 and a third spur gear 305 rotatably mounted on its two ends respectively. The second rotating shaft 306 has a fourth spur gear 307 and a fifth spur gear 308 rotatably mounted on its two ends respectively. The drying tank 2 has a second toothed ring 203 fixed to its exterior. The stirring shaft 4 has a third toothed ring 406 fixed to its exterior. The second spur gear 304 meshes with the second toothed ring 203. The third spur gear 305 meshes with the fourth spur gear 307. The fifth spur gear 308 meshes with the third toothed ring 406. The second spur gear 304, the third spur gear 305, the fourth spur gear 307 and the fifth spur gear 308 have the same diameter. The second toothed ring 203 and the third toothed ring 406 have the same diameter.

[0037] When the drying tank 2 rotates, it drives the second gear ring 203 to rotate. In turn, the second gear ring 203 meshes with the second spur gear 304 to drive the third spur gear 305 to rotate. Then, the third spur gear 305 meshes with the fourth spur gear 307 to drive the fifth spur gear 308 to rotate. Finally, the fifth spur gear 308 meshes with the third gear ring 406 to drive the stirring shaft 4 to rotate synchronously in the opposite direction relative to the drying tank 2. No additional drive device is required, making it more energy-efficient and environmentally friendly.

[0038] The first bracket 3 is hinged to the top of the base 1, and a hydraulic cylinder 101 is provided between the second bracket 301 and the base 1. The cylinder body of the hydraulic cylinder 101 is hinged to the top of the base 1, and the output shaft of the hydraulic cylinder 101 is hinged to the second bracket 301.

[0039] The extension and retraction of the hydraulic cylinder 101 can drive one side of the inlet / outlet 201 of the drying tank 2 to rise and fall. It can lift when feeding and directional when discharging, thereby improving the feeding and discharging efficiency.
