When the liquid is transmitted for heat dissipation during subsequent cooling, the liquid will cause the low temperature to gradually diffuse from one position to the surroundings, and the temperature of the raw materials cannot be fully adjusted.

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with specific embodiments.

[0033] Example 1

[0034] like Figure 1As shown, the heating reaction device for preparing stem borer insecticide of this embodiment comprises an outer ring 1, and an inner ring 8 is arranged around the inner ring 1. When heating, high-temperature steam is transmitted between the inner ring 8 and the outer ring 1 to heat the material placed in the inner ring 8, and when cooling, liquid is transmitted between the inner ring 8 and the outer ring 1. With the flow of the liquid, the liquid that absorbs heat is continuously discharged until the temperature of the material inside the inner ring 8 is reduced to the required level;

[0035] like Figure 2 As shown, in order to facilitate the preparation of the auxiliary stem borer insecticide during heating and cooling, a stirring rod 12 is arranged around the upper end of the inner ring 8, and a mounting hole 16 is arranged in the middle of the stirring rod 12. The mounting hole 16 penetrates and extends to the upper and lower ends of the middle of the stirring rod 12. After being driven, the stirring rod 12 rotates and stirs the material put inside;

[0036] A heat-conducting rod 14 is provided inside the mounting hole 16, and the heat-conducting rod 14 is located at the center of the inner ring 8 and the outer ring 1. The heat-conducting rod 14 transmits high-temperature steam and assists in heating the internal material. At the same time, the heat-conducting rod 14 transmits low-temperature liquid and assists in lowering the temperature of the material. The heat-conducting rod 14 transmits high-temperature steam or low-temperature liquid to the inside and outside of the material simultaneously, so that the material can be heated or lowered as required at the same time, avoiding stirring the material to gradually lower the temperature.

[0037] In addition, a fixed cover 4 is provided at the upper end of the outer portion of the heat-conducting rod 14, and the upper end of the stirring rod 12 is embedded in the fixed cover 4 and slidably connected with the inner portion of the fixed cover 4. The fixed cover 4 is fixedly connected to the upper end of the outer ring 1 by bolts. When the material is put in advance, when there is no fixed cover 4 covering the upper end of the inner ring 8, the material is directly put in, and when the material is put into the wrapping position of the inner ring 8, the fixed cover 4 is longitudinally slidably installed to achieve sealing and wrapping of the put-in material;

[0038] In order to facilitate the transmission of the stirring rod 12 so that the stirring rod 12 can rotate in the fixed cover 4 and stir the materials put inside, a tooth groove 13 is arranged around the position where the stirring rod 12 is embedded in the fixed cover 4. Figure 3 and Figure 5 As shown, the tooth groove 13 is welded and fixed to the stirring rod 12, a transmission cavity is provided on one side of the outside of the tooth groove 13, the transmission cavity penetrates the fixed cover 4 and extends to the outside, a first gear 6 is provided on one side of the outside of the fixed cover 4, and the first gear 6 is embedded in the transmission cavity and meshed with the outside of the tooth groove 13. After the first gear 6 is output by the motor, it drives the stirring rod 12 to rotate through the tooth groove 13;

[0039] In order to facilitate the medium transmitted between the inner ring 8 and the outer ring 1 to quickly and evenly affect the temperature of the material placed inside the inner ring 8, such as Figure 2 and Figure 4As shown, five split rings 9 are evenly distributed longitudinally between the inner ring 8 and the outer ring 1, and the inner and outer ends of the split rings 9 are respectively welded and fixed to the inner ring 8 and the outer ring 1, and the areas of the inner ring 8 and the outer ring 1 are divided by the split rings 9. The upper and lower ends of the outer side of the split ring 9 are both provided with heat conduction cavities 10, and the steam for heating and the liquid for cooling are transmitted to the inside of the heat conduction cavity 10, and the temperature of the medium put into the inner ring 8 is adjusted by the heat conduction cavity 10;

[0040] Among them, Figure 4 and Figure 7 As shown, four heat-conducting rings 11 are evenly distributed longitudinally inside the heat-conducting cavity 10, and one end of each heat-conducting ring 11 is welded and fixed to the outer wall of the inner ring 8. The heat-conducting ring 11 is welded and connected inside the inner ring 8 to conduct heat to the high-temperature steam in contact. Similarly, when the high-temperature material inside the inner ring 8 dissipates heat, it also transfers heat to the coolant inside the heat-conducting cavity 10, thereby improving the efficiency of heat dissipation and heating:

[0041] In addition, in order to facilitate the flow of liquid and steam in the heat transfer cavity 10 to quickly read the temperature, Figure 7 As shown, a second connecting pipe 3 is provided on one side of the longitudinally distributed split ring 9, and a first connecting pipe 2 is provided on one side of the second connecting pipe 3. The first connecting pipe 2 passes through the longitudinally distributed split ring 9, and the cooling liquid and steam for cooling and heating are transmitted toward the heat transfer cavity 10 through the first connecting pipe 2, and the temperature transmitted to the inside of the heat transfer cavity 10 is discharged from the second connecting pipe 3. A splitting strip 17 is provided between the first connecting pipe 2 and the second connecting pipe 3, and the splitting strip 17 is welded between the outer ring 1 and the inner ring 8;

[0042] After being divided by the dividing strip 17, the material transferred to the heat conducting cavity 10 by the first connecting tube 2 flows around the heat conducting cavity 10 and is stably discharged from the second connecting tube 3. After the first connecting tube 2 and the second connecting tube 3 are divided by the dividing strip 17, the heating and cooling media can stably and efficiently rotate clockwise in the heat conducting cavity 10.

[0043] In order to facilitate the liquid medium and the gas medium to be stably discharged from the heat conducting cavity 10 after being transmitted to the inside of the heat conducting cavity 10, and to facilitate the medium transmitted by the first connecting pipe 2 to flow evenly into the heat conducting cavity 10, a pair of solenoid valves 7 are provided inside the heat conducting cavity 10. The pair of solenoid valves 7 are respectively sealed and connected to the first connecting pipe 2 and the second connecting pipe 3 inside the heat conducting cavity 10. By adjusting the opening and closing of the solenoid valves 7, the flow positions of the high-temperature steam and the low-temperature liquid are also controlled to adapt to the amount of the material inside the inner ring 8;

[0044] Among them, the first connecting pipe 2 corresponds to the solenoid valve 7 located at the upper end of the heat conduction cavity 10, and the second connecting pipe 3 corresponds to the solenoid valve 7 located at the lower end of the heat conduction cavity 10. The second connecting pipe 3 corresponds to the solenoid valve 7 located at the lower end of the heat conduction cavity 10 to facilitate the discharge of the liquid medium after transmission, and to avoid the liquid from being retained in the heat conduction cavity 10;

[0045] Example 2

[0046] In order to facilitate the efficient discharge of the liquid after it is transferred to the heat conducting rod 14, as shown in FIG. Figure 6 As shown, third connecting tubes 5 are provided on both sides of the outer upper end of the heat-conducting rod 14, and the third connecting tubes 5 are sealed and connected to the interior of the fixing cover 4. One of the third connecting tubes 5 penetrates the fixing cover 4 and extends to the interior of the heat-conducting rod 14 through the extension tube 15, so that the liquid inside the heat-conducting rod 14 can be extracted and discharged.

[0047] The process of a heating reaction device for preparing a stem borer insecticide comprises the following steps:

[0048] Step 1: Put the medium for preparing the stem borer insecticide into the inner ring 8, drive the heat-conducting rod 14 and the stirring rod 12 with the fixed cover 4 to plug into the upper end of the outer side of the inner ring 8, and insert the bolts through the fixed cover 4 into the inner side of the outer ring 1 to fix and seal the fixed cover 4 to the upper end of the outer side of the outer ring 1;

[0049] Step 2: Start the motor corresponding to the upper end of the first gear 6. The output of the motor drives the first gear 6 to rotate. The rotation of the first gear 6 drives the stirring rod 12 to rotate through the tooth groove 13, so that the stirring rod 12 rotates in the fixed cover 4. The rotation of the stirring rod 12 stirs the material put into the inner ring 8.

[0050] Step 3: High-temperature steam is transmitted to one of the third connecting tubes 5 and the first connecting tube 2 respectively. The steam transmitted in one of the third connecting tubes 5 is transmitted to the heat-conducting rod 14, then extracted from the extended extension tube 15 and discharged from the other third connecting tube 5, while the steam transmitted in the first connecting tube 2 is transmitted to the heat-conducting cavity 10.

[0051] Step 4: The steam in the heat-conducting cavity 10 transfers its temperature to the inner ring 8 through the heat-conducting ring 11. The inner ring 8 and the heat-conducting rod 14 heat up the contacted materials, and the high-temperature steam transmitted in the heat-conducting cavity 10 is discharged from the second connecting pipe 3;

[0052] Step 5: After the material put into the inner ring 8 is completely heated, the steam is completely discharged, and the low-temperature liquid is transported to the first connecting pipe 2 and one of the third connecting pipes 5. The liquid transported in the first connecting pipe 2 flows into the heat conduction cavity 10 and is discharged from the second connecting pipe 3, while the low-temperature liquid transported in one of the third connecting pipes 5 is extracted by the extended extension pipe 15, extracted through the extension pipe 15 and discharged from the corresponding other one of the third connecting pipes 5.
