Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-3 As shown in this embodiment, a reaction vessel for pesticide production includes a reaction vessel body 100 and a stirring assembly 200. The stirring assembly 200 includes a scraper strip 207, which is made of metal material. The scraper strip 207 is fixedly installed at one end of a scraper 206. The surface of the scraper strip 207 contacts the inner wall surface of the reaction vessel body 100. One end of the scraper 206 is connected to a telescopic rod 208 by screws. One end of the telescopic rod 208 is equipped with a telescopic spring 210. One end of the telescopic spring 210 is installed inside a fixed cylinder 209. The fixed cylinder 209 is installed inside a stirring rod 204. A scraper rod 211 is installed at the lower end of the scraper 206. The lower end of the scraper rod 211 contacts the bottom end of the reaction vessel body 100.

[0024] In use, firstly, pesticide raw materials or reaction intermediates are added to the reactor body 100, and the heating or pressurization reaction process is started. The stirring rod 204 drives the scraper 206 to rotate. During the rotation, the scraper strip 207 contacts the inner wall of the reactor and scrapes off the raw materials or intermediates adhering to the inner wall. At the same time, the scraper rod 211 scrapes off the material at the bottom of the reactor to prevent the raw materials from accumulating at the bottom and ensure that the materials are mixed evenly. The telescopic spring 210 adjusts the force of the scraper 206 as needed to ensure that the pressure of the scraper strip 207 on the inner wall is moderate, avoiding damage caused by excessive force or incomplete scraping due to insufficient force. During the continuous stirring and scraping process, the pesticide raw materials are fully mixed to ensure that all raw materials participate in the reaction.

[0025] like Figures 1-2As shown, a stirring blade 205 is fixedly installed at one end of the stirring rod 204, and another end of the stirring rod 204 is fixedly installed on the outside of the rotating rod 203. The upper end of the rotating rod 203 is connected to a rotating shaft 202 by screws. The upper end of the rotating shaft 202 is installed at the lower end of the servo motor 201. The lower end of the servo motor 201 is connected to the upper end of the tank cover 101 by screws. The tank cover 101 is fixed to the upper end of the reactor body 100 by fasteners 102. In use, the rotating shaft 202 is rotated by driving the servo motor 201, which in turn drives the rotating rod 203 to rotate inside the reactor body 100, thereby driving the stirring rod 204 and the stirring blade 205 to rotate, and the reactor body 100 rotates inside.

[0026] like Figure 1 , Figures 4-6 As shown, a sliding block 213 is installed at one end of the scraper blade 207. The sliding block 213 is connected through the inside of the scraper blade 206. The sliding block 213 is slidably connected to the inside of the fixed block 212. The fixed block 212 is connected to one end of the scraper blade 206 by screws. A telescopic cylinder 217 is installed inside one side of the sliding block 213. A compression spring 219 is installed at one end of the telescopic cylinder 217. One end of the compression spring 219 is installed at one end of the moving block 220. The moving block 220 is located inside the telescopic cylinder 217. A pin 218 is installed inside the moving block 220. One end of the pin 218 is inserted into the inside of the sliding block 213. A handle 216 is installed at one end of the pin 218. A protective shell 215 is sleeved on the outside of the handle 216.

[0027] In actual use, firstly, the operator disassembles the stirring assembly 200 from the main body of the reactor, and then removes the protective shell. When the operator moves the handle 216 outward, the moving pin 218 is further moved, which in turn drives the compression spring 219 to retract inside the telescopic cylinder 217, and moves the pin 218 out from inside the sliding block 213. Then, the operator removes the scraper strip 207 from the scraper 206, and the sliding block 213 on the scraper strip 207 is moved out from inside the scraper 206. The scraper strip 207 makes the maintenance of the reactor more convenient. The scraper strip 207 can be cleaned and replaced. The removal of the scraper strip 207 allows the operator to flexibly check the wear condition of the scraper, clean its surface, or replace it, which helps to reduce the residue of deposits after long-term use.

[0028] This utility model provides a reaction vessel for pesticide production. The specific working principle is as follows: First, pesticide raw materials or reaction intermediates are added to the reaction vessel body 100, and the heating or pressurization reaction process begins. The stirring rod 204 drives the scraper 206 to rotate. During rotation, the scraper blades 207 contact the inner wall of the reaction vessel, scraping away the raw materials or intermediates adhering to the inner wall. Simultaneously, the scraper rod 211 scrapes away substances at the bottom of the reaction vessel, preventing raw materials from accumulating at the bottom and ensuring uniform mixing. The telescopic spring 210 adjusts the force of the scraper 206 as needed, ensuring that the pressure of the scraper blades 207 on the inner wall is moderate, avoiding damage from excessive force or incomplete scraping due to insufficient force. During continuous stirring and scraping, the pesticide raw materials are fully mixed, ensuring that all raw materials participate in the reaction. Through operation... The operator removes the stirring assembly 200 from the reactor body and then removes the protective shell. When the operator moves the handle 216 outward, the moving pin 218 is further moved, which in turn causes the compression spring 219 to retract inside the telescopic cylinder 217, and the pin 218 is moved out from inside the sliding block 213. Then, the operator removes the scraper strip 207 from the scraper 206, and the sliding block 213 on the scraper strip 207 is moved out from inside the scraper 206. The scraper strip 207 makes the maintenance of the reactor more convenient. The scraper strip 207 can be cleaned and replaced. The removal of the scraper strip 207 allows the operator to flexibly check the wear condition of the scraper, clean its surface, or replace it, which helps to reduce the residue of deposits after long-term use.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
