Description

Technical Field

[0001] The utility model belongs to the technical field of microemulsion stability detection, and particularly relates to a stability measurement device for mefenoxam microemulsion. Background Art

[0002] Mefenoxam is a broad-spectrum fungicide, usually used for pest control in agriculture. Microemulsion is a stable emulsion form, commonly used in pesticide formulations, which can improve the dispersibility of pesticides, reduce toxicity, increase the action time, etc. When researching and developing new mefenoxam microemulsion, the stability measurement device is crucial, which can help evaluate the physical and chemical stability of microemulsion under different conditions.

[0003] After retrieval, the existing patent (publication number: CN211553727U) discloses a rapid detection device for the stability of oral emulsion, including a housing. Both the front and rear sides of the housing are connected with connecting pipes through reset rotating shafts, and the connecting pipes are nested outside the connecting rods. The outer side of the connecting rod and the inner side of the connecting pipe are respectively welded and fixed at both ends of a tension spring, and the connecting rods are respectively fixedly connected to both ends of a pressure rod. A through hole is reserved on the upper surface of the housing, and a cover body is clamped on the through hole. A pulling groove is reserved on the upper surface of the cover body, and a twist rod is fixedly connected to the lower surface of the cover body. This rapid detection device for the stability of oral emulsion can automatically adjust the distance between the positioners according to the sample pool with different lengths, so that the positioners are located outside the upper and lower ends of the sample pool, and it can facilitate the rotation of the sample pool, so as to facilitate the detection of the data when the sample pool rotates one circle, thereby facilitating the improvement of the detection accuracy.

[0004] However, in the actual use process of the above scheme, the microemulsion usually needs to be fully stirred before use to ensure the uniform distribution of the active ingredients therein. If not stirred before testing, the test results cannot reflect the dispersibility and stability problems that the microemulsion may encounter during actual use.

[0005] Therefore, the utility model provides a stability measurement device for mefenoxam microemulsion. Content of the Utility Model

[0006] In order to make up for the deficiencies of the existing technology and solve the problem that without stirring before testing, the test results cannot reflect the dispersibility and stability that the microemulsion may encounter during actual use, the utility model provides a stability measurement device for mefenoxam microemulsion.

[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: A stability measurement device for an oxazole-acetamide microemulsion according to the present utility model includes a mixing barrel. A motor is fixedly connected to the top end of the mixing barrel. The output end of the motor is fixedly connected to a first transmission rod. The bottom end of the first transmission rod is fixedly connected to a transmission box. Evenly distributed first bevel gears are rotatably connected to the inner middle end of the transmission box. Stirring blades are fixedly connected to the outside of the first bevel gears. A support rod is rotatably connected to the inner bottom end of the transmission box. A second bevel gear is fixedly connected to the top end of the support rod. The second bevel gear is meshed with the first bevel gear. The bottom end of the support rod is fixedly connected to a support frame. The support frame is fixedly connected to the inner bottom end of the mixing barrel.

[0008] Further, a connecting rod is fixedly connected to the bottom end of the transmission box. Evenly distributed cleaning rods are fixedly connected to the outside of the bottom end of the connecting rod.

[0009] Further, a filter box is fixedly connected to the bottom end of the mixing barrel. A filter plate is fixedly connected to the inner middle end of the filter box. The filter plate is rotatably connected to the cleaning rod.

[0010] Further, a delivery pipe is fixedly connected to the bottom end of the filter box. A vacuum machine is fixedly connected to the middle end of the delivery pipe. The end of the delivery pipe away from the filter box is fixedly connected to a detection host.

[0011] Further, a cover plate is fixedly connected to the top end of the mixing barrel. Evenly distributed support legs are fixedly connected to the outer wall of the mixing barrel.

[0012] Further, a heat preservation layer is arranged inside the mixing barrel.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. For the stability measurement device for an oxazole-acetamide microemulsion according to the present utility model, the motor drives the transmission box to rotate simultaneously through the first transmission rod. The transmission box drives the first bevel gear and the stirring blades to revolve. The second bevel gear at the bottom limits the first bevel gear, causing the first bevel gear and the stirring blades to rotate. Thus, the microemulsion can be mixed more evenly, ensuring the uniform distribution of the active ingredients therein.

[0015] 2. For the stability measurement device for an oxazole-acetamide microemulsion according to the present utility model, the first transmission rod drives the cleaning rod to rotate through the connecting rod. Before detection, the microemulsion is filtered by the filter plate, and at the same time, the impurities filtered on the surface of the filter plate are cleaned by the cleaning rod, thus preventing the filter holes on the filter plate from being blocked and affecting the use of subsequent equipment.
