Description

Technical Field

[0001] This utility model relates to the field of pesticide production equipment technology, and in particular to a pesticide soluble solvent reaction vessel. Background Technology

[0002] The production of pesticides requires a lot of production equipment, and the production of some pesticides even requires multiple intermediate steps. Among them, the reaction vessel is a piece of equipment that is used frequently.

[0003] Currently, there is an existing pesticide reaction vessel, with publication number (CN204619995U), which includes a vessel body and a control console. The vessel body has an inlet and an outlet. A motor is located at the top of the vessel body, and a stirring shaft is located inside the vessel body. The upper end of the stirring shaft is connected to the output end of the motor, and a frame stirrer is located at the bottom of the stirring shaft. A nitrogen pipe is also located inside the vessel body, with its upper end located outside the vessel body and its lower end having an annular pipe with evenly distributed vent holes. A vertical pipe and several horizontal pipes are located outside the vessel body. The horizontal pipes connect the vessel body and the vertical pipes, and an exhaust pipe is located at the top of the vertical pipes. A pressure sensor is located between the exhaust pipe and the vertical pipe, and the signal output end of the pressure sensor is connected to the control console via a circuit. This utility model has a simple structure, high monitoring accuracy, and can remotely monitor and control the amount of various raw materials added. The pressure sensor has a long service life and is easy to replace. Furthermore, during the reaction process, nitrogen is added to the inside of the vessel body through the nitrogen pipe, ensuring thorough mixing of the raw materials.

[0004] During the implementation of the existing technical solution, at least the following technical problems were found:

[0005] When the existing reactor is used in pesticide production, pesticide formulations require the addition of surfactants such as emulsifiers and dispersants to stabilize the system. However, if the amount of surfactant exceeds the critical micelle concentration (CMC), the excess molecules will form a densely oriented film on the liquid surface, significantly reducing the surface tension. This makes it difficult for air bubbles entrained during stirring to break up, gradually accumulating into floating foam. The floating foam occupies the internal space of the reactor, hindering the contact and mixing between materials, resulting in an uneven reaction system. The existing solution is to equip the agitator with a defoaming paddle (such as serrated or comb-shaped blades) to break the surface tension of the foam through high-speed rotation and directly tear the foam. However, since the amount of pesticide to be mixed each time is different, it is not always possible to ensure that the liquid level is level with the defoaming paddle, and the defoaming paddle may not come into contact with the floating foam. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a pesticide soluble solvent reaction vessel, which solves the problem that the defoaming paddle in existing reaction vessels does not come into contact with floating foam.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pesticide soluble solvent reactor includes a reaction chamber with a discharge port at the bottom. The discharge port is equipped with a control valve. A cover plate is connected to the top flange of the reaction chamber. A mixing mechanism is rotatably connected to the axis of the cover plate. A support base is fixedly connected to the axis of the top surface of the cover plate. The mixing mechanism is located inside the support base. The mixing mechanism includes a stirring paddle. A limit rail is fixedly connected to the middle section of the stirring paddle. A floating ring is slidably connected to the surface of the stirring paddle. A groove is opened on the inner wall of the floating ring. An adjusting pipe is fixedly connected to the side wall of the floating ring. Three floats are distributed at the bottom of the floating ring. Three defoaming paddles are fixedly connected to the surface of the floating ring.

[0009] Preferably, the groove on the inner wall of the floating ring is slidably connected to the limiting rail.

[0010] Preferably, the end of the regulating tube furthest from the floating ring is threaded with a sealing cap, and the floating ring is hollow.

[0011] Preferably, the floating ring is connected to three buoys.

[0012] Preferably, the top surface of the cover plate is fixedly connected with four feed ports.

[0013] Preferably, a geared motor is fixedly installed on the top of the support base, and the output end of the geared motor is fixedly connected to the stirring paddle.

[0014] Preferably, a heat-conducting jacket is fixedly connected to the surface of the reaction chamber. The heat-conducting jacket includes an outer shell and a heat-conducting pipe. Three support members are fixedly connected to the surface of the heat-conducting jacket.

[0015] Preferably, the two ends of the heat-conducting pipe inside the heat-conducting jacket are fixedly connected to an oil inlet pipe and an oil outlet pipe, respectively. The oil inlet pipe and the oil outlet pipe are connected to an external heater and an oil pump. A pressure relief pipe is fixedly connected to the middle section of the heat-conducting pipe. The pressure relief pipe is connected to an external pressure relief oil tank. A temperature sensor is fixedly connected to the surface of the heat-conducting jacket. The temperature sensor passes through the heat-conducting jacket and the reaction chamber and extends into the inside of the reaction chamber.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this application, materials are added to the reaction chamber through various feed ports. A geared motor drives an agitator to stir and mix the materials inside. A heat-conducting jacket heats the materials. During the stirring and mixing process, the floating ring is rotated by the limiting rail through the groove. The floating ring floats on the liquid surface under the action of three floats, ensuring that the floating ring and the defoaming paddle are always above the liquid surface and are not affected by the amount of pesticide solution in the reaction chamber. The floating ring is always in contact with the floating foam within a certain range, thus solving the problem that the defoaming paddle of the existing reaction vessel does not come into contact with the floating foam.
