AI Technical Summary
During the production process of nicosulfuron, the two-way twisted dragon cross-mixuron stirring and drying method causes the material to adhere to the blades, locally overheat, and reduce the yield rate.
A drying device for production of nicosulfuron is designed, including a horizontal mixing tank, a vibrating motor, an eccentric cam and a compression spring. The materials are vibrated from the spiral blades through up and down vibrations, preventing local high temperatures and increasing the yield rate.
Through up and down vibration, the material can be effectively prevented from adhesion, the yield of the drying process can be improved, the material can be mixed fully, and local high temperatures can be avoided.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nicosulfuron production, in particular to a drying device for nicosulfuron production. Background Art
[0002] During the production of Nicosulfuron, 2-ethoxycarbonylaminosulfonyl-N, N-dimethylnicotinamide, 2-amino-4, 6-dimethoxypyrimidine, a phase transfer catalyst and a solvent are added for stirring and synthesis, and the material is discharged, centrifuged and dried to obtain the Nicosulfuron finished product. The drying of the Nicosulfuron finished product generally adopts a two-way auger for horizontal stirring, and the outer cylinder is heated to evaporate the water. This type of drying method has the problem that the material adheres to the auger blades and is locally overheated, resulting in a reduced yield rate. Utility Model Content
[0003] In order to solve the problem of reduced yield during drying of Nicosulfuron production, the utility model provides a drying device for Nicosulfuron production.
[0004] The technical solution provided by the utility model is: a drying device for the production of Nicosulfuron, comprising a horizontal mixing tank, a support leg is arranged at the lower part of the horizontal mixing tank, a base is welded at the bottom of the support leg, a guide seat is installed under the base, a circle of enclosure plates extends upward from the guide seat, the enclosure plates are sleeved on the outer side of the support leg, a vibration motor is installed on the guide seat, an eccentric cam is installed on the output shaft of the vibration motor, and a compression spring is installed between the guide seat and the base.
[0005] A guide rail is provided on the outer side of the support leg, a dovetail groove is opened on the inner side of the enclosure, the guide rail and the dovetail groove are connected by a guiding fit, and the guide rail is made of ductile iron.
[0006] The beneficial effects of the utility model are as follows: by arranging a vibration motor at the lower part of the horizontal mixing tank, when the eccentric cam rotates, the horizontal mixing tank vibrates up and down, and the materials adhering to the spiral blades are shaken off. The up and down vibration makes the materials mixed more fully, prevents the materials from generating local high temperature, and improves the yield rate of the drying process. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Attached Figure 1 It is a structural schematic diagram of the utility model.
[0008] In the figure, 1-horizontal mixing tank, 2-support legs, 3-base, 4-guide seat, 5-vibration motor, 6-eccentric cam, 7-compression spring, 8-enclosure plate, 9-guide rail, 10-dovetail groove. DETAILED DESCRIPTION
[0009] like Figure 1As shown, a drying device for the production of Nicosulfuron comprises a horizontal mixing tank 1, a leg 2 is provided at the lower part of the horizontal mixing tank 1, a base 3 is welded at the bottom of the leg 2, a guide seat 4 is installed under the base 3, a circle of enclosure 8 is extended upward from the guide seat 4, and the enclosure 8 is sleeved on the outer side of the leg 2, a vibration motor 5 is installed on the guide seat 4, an eccentric cam 6 is installed on the output shaft of the vibration motor 5, and a compression spring 7 is installed between the guide seat 4 and the base 3. By arranging the vibration motor 5 at the lower part of the horizontal mixing tank 1, when the eccentric cam 6 rotates, the horizontal mixing tank 1 vibrates up and down, and the material adhered to the spiral blade is shaken off. The up and down vibration makes the material mixing more complete, prevents the material from generating local high temperature, and improves the yield rate of the drying process.
[0010] A guide rail 9 is provided on the outside of the support leg 2, and a dovetail groove 10 is opened on the inside of the enclosure 8. The guide rail 9 and the dovetail groove 10 are connected with each other in a guiding manner. The guide rail 9 of the horizontal mixing tank 1 moves up and down along the dovetail groove 10, and the operation is more stable. The guide rail 9 is made of ductile iron to play a lubricating role.
