Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a raw material emulsification reactor for pesticide production. Background Art

[0002] Pesticides are chemical substances or mixtures used to prevent, control or eliminate plant pests, weeds and other harmful organisms. Reactors are required for emulsification in the emulsification process of pesticide production. Reactors are broadly understood as containers for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are achieved. Reactors are widely used in the fields of chemical industry, pesticides, dyes, food, etc. They are mainly pressure vessels used to complete processes such as sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation.

[0003] A reactor with publication number CN116712955A in the prior art is provided with an inner stirring shaft in the reactor body and a detachable outer stirring shaft is fixed by a fixing unit.

At the same time, a clamping installation unit is provided at the lower end of the outer stirring shaft to clamp the filter paper, and the filter paper is placed at the bottom of the reactor body close to the inner wall of the reactor body. In this way, after the reaction is completed and the liquid solvent is discharged, when the outer stirring shaft is taken out, the fixed substance produced by the reaction will be precipitated on the filter paper and then taken out. In this way, solid-liquid separation can be achieved quickly and the overall cleaning of the reactor body is also convenient.

Specific embodiments

[0019] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0021] Such as Figures 1-9A raw material emulsification reactor for pesticide production as shown, includes a control cabinet 1, and a kettle body 2 fixedly connected beside the control cabinet 1. There is a kettle cover 3 above the kettle body 2. Here, it should be noted that there is a sealing structure between the kettle cover 3 and the kettle body 2 to ensure the sealing effect during the pesticide emulsification reaction process. There is a top box 4 on the top of the control cabinet 1. There is a connecting cylinder 5 fixedly connected between the top of the kettle cover 3 and the bottom of the top box 4. Inside the control cabinet 1, there is a jacking mechanism for driving the top box 4 to move upward. The center position at the bottom of the kettle cover 3 is rotatably connected with a round rod 6. Here, it should be noted that the height of the round rod 6 does not exceed the bottom end of the kettle cover 3, otherwise it will affect the normal replacement of the device. There is a rotating motor 7 fixedly connected to the bottom of the top box 4. Below the rotating motor 7, there is a half-ring-shaped replacement plate 8. At both ends of the replacement plate 8, there are respectively an I-shaped upper arc groove 9 and an I-shaped lower arc groove 10. Below the round rod 6, there is a stirring frame 11. An installation arc groove 12 is opened at the bottom of the round rod 6. Inside the replacement plate 8, there is a T-shaped frame 28 fixedly connected. The output end of the rotating motor 7 is fixedly connected to the top of the T-shaped frame 28. The outer wall of the rotating motor 7 is fixedly connected with a support frame 29. The support frame 29 is fixedly connected to the bottom of the top box 4. Through the setting of the support frame 29, the stability of the rotating motor 7 is further improved, thereby increasing the stability during the operation of the equipment; The jacking mechanism includes a pair of electric telescopic cylinders 21. The electric telescopic cylinders 21 are both fixedly connected inside the control cabinet 1. The output ends of the electric telescopic cylinders 21 pass through the top end of the control cabinet 1 and are fixedly connected to the bottom of the top box 4. At the inner bottom end of the top box 4 and above the kettle body 2, there is a stirring motor 22 fixedly connected. The output end of the stirring motor 22 passes through the top box 4 and the kettle cover 3 and is fixedly connected to the round rod 6; During use, the pesticide raw materials are added through the feed port on the kettle cover 3. Subsequently, control the stirring motor 22 to start and drive the round rod 6 to rotate. At this time, since the U-shaped block 15 is inserted into the locking groove 18, the round block 13 will be pushed to rotate simultaneously through the U-shaped block 15 when the round rod 6 rotates, and then drive the bottom stirring frame 11 to rotate, realizing the mixing reaction of the pesticide raw materials in the kettle body 2. Finally, the pesticide after the emulsification reaction is discharged through the discharge port at the bottom of the kettle body 2.

[0022] A round block 13 fixedly connected to the top of the stirring frame 11 is adapted to the installation arc groove 12. A circular rod 6 is slidably connected through the outer wall of an L-shaped rod 14. One end of the L-shaped rod 14 is fixedly connected to a U-shaped block 15, and the other end of the L-shaped rod 14 is fixedly connected to an extrusion rod 16. An annular groove 17 is formed in the outer wall of the round block 13 at a position corresponding to the lower arc groove 10. A locking groove 18 in the shape of a half ring is formed in the outer wall of the round block 13 at a position corresponding to the U-shaped block 15. The top end of the replacement plate 8 is fixedly connected to an arc plate 19. Here, it should be noted that the end of the arc plate 19 far from the lower arc groove 10 is arranged at a position corresponding to the center of the upper arc groove 9. Thus, after the new stirring frame 11 is screwed into the installation arc groove 12, the extrusion of the extrusion rod 16 can be released, and the position of the round block 13 can be quickly locked. The end of the arc plate 19 close to the lower arc groove 10 is obliquely and fixedly connected to an inclined plate 20. The bottom of the extrusion rod 16 extends to a position where it can be squeezed by the inclined plate 20. A pair of upper springs 23 are fixedly connected between the extrusion rod 16 and the outer wall of the circular rod 6. Through the setting of the upper springs 23, it is convenient for the arc plate 19 to slide away from beside the extrusion rod 16. When releasing the extrusion of the extrusion rod 16, the extrusion rod 16 is pushed to quickly reset. The outer wall of the extrusion rod 16 is set as a smooth arc surface, which is convenient for the inclined plate 20 to push the extrusion rod 16 to move more smoothly, improving the smoothness during the operation of the device; When it is necessary to clean the inside of the kettle body 2 after the pesticide emulsification reaction is discharged, the inside of the kettle body 2 is rinsed through a cleaning device (since there are many structures on the stirring frame 11 and there are many dead points, it is impossible to completely clean the stirring frame 11 only by rinsing). Then, after the rinsing is completed, first insert the round block 13 on the cleaned stirring frame 11 into the upper arc groove 9 through the annular groove 17 (it is not the same stirring frame 11 as that in the kettle body 2). Then, the electric telescopic cylinder 21 of the jacking mechanism can be controlled to start and push the top box 4 to move upward, simultaneously driving the rotary motor 7 and the kettle cover 3 to move upward. Furthermore, the kettle cover 3 is separated from the kettle body 2, and at the same time, the stirring frame 11 in the kettle body 2 and the stirring frame 11 on the replacement plate 8 are driven to move upward. Then, after the stirring frame 11 is completely lifted out of the kettle body 2; The rotation motor 7 can be controlled to start, driving the T-shaped frame 28 and the replacement plate 8 to rotate, so that the replacement plate 8 rotates under the kettle cover 3, and then the lower arc groove 10 is inserted into the annular groove 17 on the round rod 6. At the same time, the unlocking rod 30 inside the replacement plate 8 will move under the roller 33, and then gradually push the roller 33 to slide upward through the inclined surface at the end of the unlocking rod 30, thereby driving the lower rod 31 to move upward, driving the L-shaped limiting rod 26 to move upward at the same time, and compressing the lower spring 27, so as to release the sliding restriction on the round block 13. Subsequently, with the continuous rotation of the replacement plate 8, the roller 33 moves to the top of the unlocking rod 30, and at the same time, the inclined plate 20 on the replacement plate 8 will rotate beside the extrusion rod 16. Since the inclined plate 20 is inclined, driving the replacement plate 8 to continue to rotate through the rotation motor 7 will push the extrusion rod 16 to move through the inclined plate 20, thereby driving the L-shaped rod 14 and the U-shaped block 15 to move, so that the U-shaped block 15 moves out of the locking groove 18 and gradually compresses the upper spring 23. Subsequently, with the continuous rotation of the replacement plate 8, the extrusion rod 16 moves beside the arc plate 19, maintaining the extrusion of the extrusion rod 16, so as to release the position restriction on the round block 13 (at this time, since the lower arc groove 10 is I-shaped, the unlocked round block 13 will not fall). Subsequently, under the action of the lower arc groove 10, the round block 13 and the stirring frame 11 are taken away, thereby realizing the automatic removal of the stirring frame 11 and improving the convenience of the device.

[0023] To ensure the normal operation of the device, the round rod 6 is set in an inverted T shape, and a lower positioning sensor 24 is fixedly connected to the top of the round rod 6, and an upper positioning sensor 37 is fixedly connected to the bottom of the kettle cover 3. Through the settings of the lower positioning sensor 24 and the upper positioning sensor 37, when the reaction kettle stops operating, it can ensure that the round rod 6 rotates to the initial position, so that the extrusion rod 16 rotates to a position where it can be squeezed by the inclined plate 20, thus avoiding affecting the normal replacement of the subsequent stirring frame 11.

[0024] In order to be able to install the new stirring frame 11 on the reaction kettle, an L-shaped groove 25 is opened at the top of the installation arc groove 12 and outside the round block 13. The L-shaped groove 25 is arranged on the side away from the lower arc groove 10. An L-shaped limiting rod 26 for restricting the sliding position of the round block 13 is slidably connected inside the L-shaped groove 25. A pair of lower springs 27 are fixedly connected between the top of the L-shaped limiting rod 26 and the top of the L-shaped groove 25. A lower rod 31 is fixedly connected to the side wall of the L-shaped limiting rod 26, and an unlocking rod 30 in the shape of a quarter ring is fixedly connected to the inside of the replacement plate 8. The unlocking rod 30 is inclined on the side close to the lower arc groove 10; When the stirring rack 11 in the reactor body 2 is removed from the changing plate 8 and the stirring rack 11 that needs to be cleaned is removed, the changing plate 8 is further driven to rotate by the rotating motor 7. At this time, the stirring rack 11 taken out will be rotated out from the top of the reactor body 2, and the stirring rack 11 in the upper arc groove 9 will be rotated to the bottom of the reactor cover 3. Before that, when the stirring rack 11 in the lower arc groove 10 is rotated out from under the reactor cover 3, the roller 33 will move out from the unlocking rod 30, and then push the L-shaped limiting rod 26, the lower rod 31 and the roller 33 to slide downward under the elastic force of the lower spring 27, and then the L-shaped limiting rod 26 will limit the round block 13 that slides into the inner side of the subsequent installation arc groove 12, and then the round block 13 rotates into the installation arc groove 12, and then the round block 13 rotates into the installation arc groove 12, and then the round block 13 rotates into the installation arc groove 12, and under the limitation of the L-shaped limiting rod 26, the round block 13 in the upper arc groove 9 cannot continue to rotate with the changing plate 8, so that when the changing plate 8 continues to rotate, it will be The U-shaped magnet 35 is pushed into the locking groove 18 by the upper spring 23. The upper spring 23 pushes the U-shaped block 15 and the upper spring 23 pushes the U-shaped block 15 to move and rotate.

[0025] In order to improve the smoothness of the device during operation, an inward groove 32 is opened at the bottom of the lower rod 31, and a roller 33 is rotatably connected to the inside of the groove 32. Through the arrangement of the groove 32 and the roller 33, when the lower rod 31 moves to the top of the unlocking rod 30, the sliding friction when the lower rod 31 contacts the unlocking rod 30 can be converted into rolling friction, which makes it easier for the unlocking rod 30 to squeeze the lower rod 31 up, thereby improving the smoothness of the device during operation.

[0026] In order to prevent the round block 13 placed on the upper arc-shaped groove 9 from rotating and affecting subsequent normal installation, a lower groove 34 is opened on the inner side of the upper arc-shaped groove 9, and a U-shaped magnet 35 is fixedly connected to the inner side of the lower groove 34. The round block 13 is made of a material that can be adsorbed by the U-shaped magnet 35. Through the setting of the U-shaped magnet 35, after the round block 13 is inserted into the upper arc-shaped groove 9, it can play a certain role in restricting the position of the round block 13, avoiding the movement of the round block 13 caused by shaking during the rotation of the replacement plate 8 driven by the rotating motor 7, which may cause too much deviation when the U-shaped block 15 is inserted into the locking groove 18 subsequently. And when the replacement plate 8 drives the round block 13 on the upper arc-shaped groove 9 to rotate into the installation arc-shaped groove 12, at this time, the L-shaped limiting rod 26 will restrict the sliding position of the round block 13 and gradually push the round block 13 out of the U-shaped magnet 35, thus not affecting the normal replacement of the device. An indication arrow 36 for indicating the insertion direction of the round block 13 is opened on the top of the replacement plate 8 and beside the upper arc-shaped groove 9. Through the setting of the indication arrow 36, it is convenient for the staff to place the locking groove 18 at the designated position when inserting the round block 13 on the stirring frame 11 into the upper arc-shaped groove 9, facilitating the subsequent quick insertion and locking of the U-shaped block 15.
