A discharge valve 4 is fixedly connected to the output end of the guiding hopper 2. A stirring rod 5 is horizontally and bearing-connected to the middle and lower part inside the raw material synthesis tank 1. A driving motor 6 is fixedly connected to the middle and lower part on the right of the raw material synthesis tank 1, and the left end of the output shaft of the driving motor 6 penetrates through the inside of the raw material synthesis tank 1 in a sealed manner. The left end of the output shaft of the driving motor 6 is connected to the right end of the stirring rod 5 through a coupling.

[0014] One of the raw material synthesizers for flonicamid production further includes a vacuum suction feeding and premixing assembly 7, and the vacuum suction feeding and premixing assembly 7 is fixedly connected to the opening at the middle part of the upper part of the raw material synthesis tank 1 in a sealed manner, which is beneficial to achieving the premixing effect, thus effectively shortening the stirring time and further improving the production efficiency of flonicamid.

[0015] In this embodiment, in combination with the attached Figure 3 As shown in the figure, the vacuum suction feeding and premixing assembly 7 includes a premixing cylinder 70. An integrated suction pipe 71 is connected to the opening at the middle part of the upper part of the premixing cylinder 70, and a filter screen 72 is fixedly connected to the middle part inside the suction pipe 71. A centrifugal fan 73 is fixedly connected to the upper end of the suction pipe 71 in a sealed manner. Connecting rods 74 are longitudinally and fixedly connected to the peripheral parts of the upper inner side of the premixing cylinder 70 respectively, and a spherical arc baffle 75 is fixedly connected to the lower ends between the connecting rods 74. Feed pipes 76 are integrally connected to the openings at the peripheral parts of the upper side inside the premixing cylinder 70 respectively. The feed pipes 76 are located outside the spherical arc baffle 75 respectively, and the lower ends of the feed pipes 76 are bent inward to the inner side of the spherical arc baffle 75. The center lines of the inclined sections of the feed pipes 76 all pass through the midpoint of the spherical arc baffle 75. Feed valves 77 are fixedly connected to the upper ends of the feed pipes 76 in a sealed manner, and connecting pipes 78 are fixedly connected to the upper ends of the feed valves 77 in a sealed manner. Suction hoses 79 are fixedly connected to the upper ends of the connecting pipes 78.

[0016] In this embodiment, specifically, the lower part of the premixing cylinder 70 is fixedly connected to the opening at the middle part of the upper part of the raw material synthesis tank 1 in a sealed manner.

[0017] In this embodiment, specifically, the premixing cylinder 70 is made of a stainless steel cylinder with a circular cross-section.

[0018] In this embodiment, specifically, the filter screen 72 is made of a primary effect plate air filter screen.

[0019] In this embodiment, specifically, the spherical arc baffle 75 is made of a spherical arc-shaped stainless steel plate.

[0020] In this implementation scheme, specifically, the suction hose 79 is made of PVC plastic hose.

[0021] In this implementation scheme, specifically, the discharge valve 4 is an electric slide gate valve.

[0022] In this implementation scheme, specifically, the feed valve 77 is a solenoid valve.

[0023] In this implementation scheme, specifically, the discharge valve 4, the feed valve 77, the drive motor 6 and the centrifugal fan 73 are respectively electrically connected to an external control panel.

[0024] In this implementation scheme, during feeding, the operator can first insert the input end of the suction hose 79 into the external raw materials respectively, and then can open the corresponding feed valve 77 through the external control panel, and at the same time turn on the centrifugal fan 73, so that the centrifugal fan 73 sucks the air in the pre-mixing cylinder 70 through the suction pipe 71, so that the inside of the pre-mixing cylinder 70 presents a negative pressure state. At this time, the feed pipe 76 will generate suction force. Since the feed pipe 76 is connected to the suction hose 79 through the feed valve 77 and the connecting pipe 78, the suction hose 79 will suck the raw materials. When the raw materials enter the inside of the feed pipe 76, because the center lines of the inclined sections of the feed pipe 76 all pass through the midpoint of the spherical arc baffle 75, and because the raw materials have a certain inertia when discharged from the output end of the feed pipe 76, when the raw materials are discharged from the output end of the feed pipe 76, collisions will occur between various raw materials, so as to achieve the purpose of preliminary mixing. Subsequently, the preliminarily mixed raw materials will fall into the raw material synthesis box 1. Compared with the prior art, the utility model can preliminarily mix the raw materials, so that the materials to be stirred are in a mixed state, and thus the stirring time of the raw materials can be effectively shortened, and then the production efficiency of flonicamid can be improved, realizing the effect of pre-mixing.

[0025] Any technical solution using the technical solution of the present utility model, or designed by those skilled in the art inspired by the technical solution of the present utility model to achieve the above technical effects, shall fall within the protection scope of the present utility model.
