DETAILED DESCRIPTION
[0022] 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.
[0023] See also Figure 1-3The utility model provides a technical solution: a drying device for producing 2,4-diaminopyrimidine-3-oxide, comprising a microwave oven cabinet 1, a microwave heating mechanism 200 for heating is fixedly installed on the inner side of the microwave oven cabinet 1, a flipping and scattering component 300 for breaking up the 2,4-diaminopyrimidine-3-oxide is installed on the inner side of the microwave oven cabinet 1, and a collecting component 400 for collecting the 2,4-diaminopyrimidine-3-oxide is installed on the inner side of the microwave oven cabinet 1; through the microwave heating mechanism 200 inside the microwave oven cabinet 1 and the coordinated use between the flipping and scattering component 300 and the collecting component 400, the powdered oxide can be dried more efficiently, not only the oxide powder can be conveniently put in and taken out, which is convenient for continuous drying work, but also the oxide powder can be conveniently dropped more efficiently, which is beneficial to improving the overall drying efficiency, thereby effectively improving the practicality of the drying device for the oxide.
[0024] It should be noted that the front of the microwave oven cabinet 1 is hinged with a door, and the front opening of the microwave oven cabinet 1 can be opened or closed by the door. The microwave heating mechanism 200 is a device that can use microwaves for heating. Microwave heating is the process of heating an object by using the energy characteristics of microwaves, and it is an existing public technology, so it will not be elaborated in detail.
[0025] In this embodiment, the turning and breaking component 300 is a structure for breaking up 2,4-diaminopyrimidine-3-oxide more efficiently so that it falls down quickly for drying.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the flipping and breaking up component 300 includes a conveying barrel 301 fixed to the top of the microwave oven body 1, a transmission rod 302 rotatably connected to the inner side of the conveying barrel 301 through a bearing, a driving motor 303 fixedly installed on the top of the conveying barrel 301, a stirring plate 304 fixed to the outer side of the transmission rod 302 and evenly distributed, a plurality of stirring rods 305 fixed to the outer side of the transmission rod 302 and of different lengths, a filter plate 306 fixed to the inner side of the conveying barrel 301, four fixed plates 307 fixed to the outer side of the transmission rod 302, a scraper 308 fixed to the bottom of the fixed plate 307, two inclined plates 309 fixed to the outer side of the transmission rod 302, and rake teeth 310 fixed to the bottom of the inclined plate 309 and evenly distributed.
[0027] It should be noted that the driving motor 303 can be a servo motor, the top of the conveying barrel 301 passes through the top of the microwave oven housing 1, and an entrance port for 2,4-diaminopyrimidine-3-oxide to enter is provided at the top of the conveying barrel 301. The top of the conveying barrel 301 is hinged with a lid located at the top of the entrance port by a hinge, and a sealing insulation pad is fixed to the bottom of the lid that abuts against the top of the inner side of the entrance port, so that 2,4-diaminopyrimidine-3-oxide can enter the interior of the conveying barrel 301 through the entrance port from the outside, and with the cooperation of the lid and the sealing insulation pad, the internal heat can be prevented from being lost through the entrance port, thereby playing a role of sealing and heat insulation.
[0028] In addition, the conveying barrel 301 consists of a main barrel, a conical barrel fixed to the bottom of the main barrel, and a discharge barrel fixed to the bottom of the conical barrel. The inner diameter of the main barrel is larger than the inner diameter of the discharge barrel, and the bottom of the discharge barrel is open. The stirring rod 305 is located inside the conical barrel, so that the 2,4-diaminopyrimidine-3-oxide inside the conveying barrel 301 can be smoothly transported from top to bottom, and there is a corresponding stirring and breaking structure in each space to facilitate its dispersion and falling.
[0029] At the same time, the cross-section of the scraper 308 is triangular, and the bottom of the scraper 308 fits with the top of the filter disc 306, so that the 2,4-diaminopyrimidine-3-oxide on the top of the filter disc 306 can fall through the filter disc 306 more quickly under the push of the scraper 308, thereby improving the dispersion and falling rate, so that the 2,4-diaminopyrimidine-3-oxide can reach a dispersed state more quickly, which is conducive to the efficient drying work.
[0030] In this embodiment, the collecting assembly 400 is a structure for placing, drying and collecting 2,4-diaminopyrimidine-3-oxide.
[0031] like Figure 1 As shown, the collecting assembly 400 includes four supporting rods 401 fixed to the inner bottom wall of the microwave oven body 1, a drying box 402 fixed between the top ends of the four supporting rods 401, an output pipe 403 fixed to the bottom of the drying box 402, a valve 404 fixedly installed on the outside of the output pipe 403, and a collecting box 405 placed on the inner bottom wall of the microwave oven body 1.
[0032] It should be noted that the top of the drying box 402 is open, the inner wall of the drying box 402 is conical, and the inclined plate 309 is parallel to the inner wall of the drying box 402. The bottom end of the transmission rod 302 passes through the top of the filter plate 306 and extends to the interior of the drying box 402, so that the inclined plate 309 can drive the rake teeth 310 to rotate normally inside the drying box 402, thereby achieving a good flipping effect on the 2,4-diaminopyrimidine-3-oxide inside.
[0033] It should also be noted that 2,4-diaminopyrimidine-3-oxide is in powder form. Through the use of this equipment, it can achieve good dispersion and drying effects, so that the 2,4-diaminopyrimidine-3-oxide particles are distinct after the drying work is completed. Moreover, this drying equipment can not only be used for the production drying of 2,4-diaminopyrimidine-3-oxide, but also can be used for drying other powdery substances. Its applicability is very wide.
[0034] The working principle of the above embodiment is:
[0035] When drying 2,4-diaminopyrimidine-3-oxide, pour 2,4-diaminopyrimidine-3-oxide into the interior of the conveying barrel 301, start the driving motor 303, drive the transmission rod 302 to rotate, so that the 2,4-diaminopyrimidine-3-oxide in the upper part of the conveying barrel 301 can be effectively pushed, and the 2,4-diaminopyrimidine-3-oxide in the middle part can be scattered with the stirring rods 305 of different lengths, and the 2,4-diaminopyrimidine-3-oxide at the top of the filter plate 306 falls rapidly under the rotation of the scraper 308 and enters the interior of the drying box 402, so that the 2,4-diaminopyrimidine-3-oxide dispersed by the filter plate 306 is easy to dry, and the microwave heating mechanism 200 is started to heat the interior of the microwave oven cabinet 1. The temperature is raised by heating, and with the cooperation of the inclined plate 309 and the rake teeth 310, the 2,4-diaminopyrimidine-3-oxide inside the drying box 402 can be effectively dispersed and promoted, so that the heat can be efficiently transferred, which is convenient for the efficient drying work. After the drying work is completed, the microwave oven body 1 is opened, and the collection box 405 is placed under the output pipe 403, and the valve 404 is opened, so that the 2,4-diaminopyrimidine-3-oxide inside the drying box 402 can be discharged through the output pipe 403 to the inside of the collection box 405 for collection. After the collection box 405 is removed from the inside of the microwave oven body 1, the microwave oven body 1 is closed, and the operation is repeated according to the above principle, and the drying work of other 2,4-diaminopyrimidine-3-oxides can be carried out again, so that the drying work can be carried out smoothly.
[0036] Compared with the prior art, the drying equipment for producing 2,4-diaminopyrimidine-3-oxide can dry powdered oxides more efficiently through the cooperation between the microwave heating mechanism 200 inside the microwave oven cabinet 1 and the flipping and breaking up component 300 and the collecting component 400. It can not only conveniently put in and take out the oxide powder, which is convenient for continuous drying work, but also facilitate the more efficient falling of the oxide powder, which is beneficial to improving the overall drying efficiency, thereby effectively improving the practicability of the drying equipment for oxides and solving the problem that the process connection of the existing microwave drying equipment for oxides is not coherent during the actual operation, which affects the overall drying efficiency.
