However, during use, the traditional 1-(difluoromethyl)-1h-pyrazole-4-amine pretreatment device is generally only capable of pretreatment, while the reaction requires another device for reaction, resulting in the need to set up multiple devices, which not only occupies a large space, but also requires repeated transportation of raw materials, which is not very convenient. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example 1: Pretreatment device for 1-(difluoromethyl)-1h-pyrazole-4-amine, see Figures 1 to 3, including an outer cylinder 1 of the device, a first top cover 101 is installed on the top of the outer cylinder 1 of the device, and also includes: a reaction cylinder 206, which is arranged inside the outer cylinder 1 of the device; a pretreatment mechanism, which is fixed outside the reaction cylinder 206, and the pretreatment mechanism includes a plurality of stirring blades 204, and the plurality of stirring blades 204 are respectively installed on the outer wall of the reaction cylinder 206; a plurality of fixing seats 3 are installed on the inner wall of the reaction cylinder 206, and electric heating pipes 301 are fixed inside the plurality of fixing seats 3. First, the pretreated raw materials are placed into the outer cylinder 1 of the device, and then the raw materials to be reacted are placed into the reaction cylinder 206, and then water is poured into the inner part of the outer cylinder 1 of the device. After the water is poured, the motor 2 is turned on, the motor 2 drives the motor shaft 201, the motor shaft 201 drives the rotating rod 202, and the rotating rod 202 drives the second top cover 208 and the reaction cylinder 206 to rotate, and the reaction cylinder 206 will drive the plurality of stirring blades 204 to rotate, and the reaction cylinder 206 will drive the plurality of stirring blades 204 to rotate, and the reaction cylinder 206 will drive the plurality of stirring blades 204 to rotate. A plurality of stirring blades 204 stir the raw materials in the water to wash the raw materials. During the rotation of the reaction cylinder 206, the plurality of electric heating tubes 301 inside the reaction cylinder 206 are driven to rotate. The rotation of the plurality of electric heating tubes 301 can stir and react the raw materials in the reaction cylinder 206. At the same time, the rotation of the plurality of electric heating tubes 301 can heat the raw materials in the process of stirring the raw materials, thereby improving the heating effect of the raw materials and the reaction effect. The reaction mechanism and the pretreatment water washing mechanism are combined and driven by the same driving device, thereby saving energy and solving the problem that the traditional pretreatment device of 1-(difluoromethyl)-1h-pyrazole-4-amine can generally only perform pretreatment, while the reaction requires another device for reaction, resulting in the need to set up multiple devices, which not only occupies a large space, but also requires the raw materials to be repeatedly transported, which is not a very convenient technical problem.

[0023] For details, see Figure 1 A second top cover 208 is installed on the top of the reaction cylinder 206, a rotating rod 202 is fixed on the top of the second top cover 208, a motor shaft 201 is fixed on the top of the rotating rod 202, the top of the motor shaft 201 passes through the second top cover 208 and is connected to the motor 2, and a second top cover 208 is installed on the bottom of the motor 2.

[0024] For further information, see Figure 1 A conductive slip ring 203 passes through the outside of the rotating rod 202. The conductive slip ring 203 is electrically connected to multiple electric heating tubes 301. The conductive slip ring 203 can be used in any electromechanical system that requires continuous rotation and needs to transmit power and signals from a fixed position to a rotating position. The slip ring can improve system performance, simplify system structure, and avoid twisting of the wire during rotation. Therefore, after the conductive slip ring 203 is connected to the power line of the electric heating tube 301, it can avoid the power line from being entangled during the rotation of the electric heating tube 301.

[0025] It is worth noting that see Figure 1A groove 209 is provided at the front end of each of the plurality of stirring blades 204, and a phase change thermal storage ceramic block 210 is installed inside the groove 209. During the rotation of the stirring blades 204, the phase change thermal storage ceramic can be used to store heat in the water. After the phase change thermal storage ceramic stores heat, when the temperature drops, the phase change thermal storage ceramic can continuously release heat, thereby keeping the reaction cylinder 206 warm and avoiding temperature loss in the reaction cylinder 206.

[0026] It is worth noting that see Figure 1 The upper and lower sides of the front end of the reaction cylinder 206 are both connected to one end of the connecting tube 205, and the other end of the connecting tube 205 is detachably connected to the first tube cover 207.

[0027] It is worth mentioning that see Figure 3 One end of a hinge 104 is rotatably connected to one side of the front end of the outer cylinder 1 of the device, a cylinder baffle 105 is installed at the other end of the hinge 104, an industrial control computer 106 is installed at the middle of the front end of the cylinder baffle 105, one end of a pipe 102 is connected to one side of the top and the front end of the outer cylinder 1 of the device, and the other end of the pipe 102 is detachably connected to a second pipe cover 103.

[0028] When using the pretreatment device of 1-(difluoromethyl)-1h-pyrazole-4-amine, the pretreated raw material is first placed in the outer cylinder 1 of the device, and then the raw material to be reacted is placed in the reaction cylinder 206, and then water is poured into the inner part of the outer cylinder 1 of the device. After the water is poured, the motor 2 is turned on, the motor 2 drives the motor shaft 201, the motor shaft 201 drives the rotating rod 202, and the rotating rod 202 drives the second top cover 208 and the reaction cylinder 206 to rotate. The reaction cylinder 206 drives multiple stirring blades 204 to rotate, and the multiple stirring blades 204 are used to stir the raw materials in the water to wash the raw materials. During the rotation of the reaction cylinder 206, multiple electric heating devices inside the reaction cylinder 206 are driven. The tube 301 rotates, and multiple electric heating tubes 301 rotate to stir the raw materials in the reaction cylinder 206. At the same time, multiple electric heating tubes 301 rotate to heat the raw materials during stirring, thereby improving the heating effect of the raw materials. The reaction mechanism and the pretreatment water washing mechanism are combined and driven by the same driving device, which saves energy. During the rotation of the stirring blades 204, the phase change thermal storage ceramics can be used to store heat in the water. After the phase change thermal storage ceramics store heat, when the temperature drops, the phase change thermal storage ceramics can continuously release heat, thereby keeping the reaction cylinder 206 warm and avoiding temperature loss in the reaction cylinder 206.
