Description

Technical Field

[0001] The utility model relates to the technical field of medicament preparation, in particular to a preparation device suitable for pesticide hexaconazole suspension. Background Art

[0002] Hexaconazole, a beige loose powder, is a triazole fungicide and a sterol demethylation inhibitor. It has a broad-spectrum protective and therapeutic effect on fungi, especially diseases caused by Basidiomycetes and Ascomycetes. When treating diseases, hexaconazole often needs to be mixed with special adjuvants, thickeners (such as xanthan gum), dispersants, preservatives, defoaming agents and purified water to make a suspension for use.

[0003] Currently, when preparing this type of suspension, the usual operation is to pour the ingredients into a mixing device and stir and mix them. However, simple stirring and mixing not only has low mixing efficiency, but also has problems with the stability and dispersion uniformity of the internal particles after mixing.

[0004] To this end, we propose a preparation device suitable for the pesticide hexaconazole suspension concentrate to solve the above problems. Utility Model Content

For example, they may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-3 The mixing drum 1 is provided with a raw material feeding port 4, and a main stirring rod 8 is installed in the center of the mixing drum 1 for rotation. The raw material feeding port 4 is provided on the sand mill 2, and a discharge port 6 is provided under the sand mill 2 for collecting the discharged suspension. A main shaft 9 is installed in the center of the sand mill 2 for rotation. A paddle plate 11 is connected to the outer wall of the main shaft 9 through a support rod 10, and the paddle plate 11 is in contact with the inner wall of the sand mill 2. When the main shaft 9 rotates, the paddle plate 11 is driven by the support rod 10 to stir the abrasive and the solution, so as to prevent the abrasive from accumulating at the bottom of the sand mill 2 due to gravity, thereby improving the sand milling effect.

[0026] Furthermore, the paddle 11 adopts a hollow mesh structure, so that when the abrasive is stirred, it is easy to filter through the mesh, thereby improving the dispersion and mixing effect of the solution.

[0027] See also Figure 1-3 The end of the main shaft 9 extending out of the sanding cylinder 2 is installed with a bevel gear 12, and the outer end of the bevel gear 12 is connected to the motor 14. The end of the main stirring rod 8 extending out of the mixing cylinder 1 is installed with a bevel gear 2 13, and the bevel gear 2 13 is vertically meshed with the bevel gear 12, so that the motor 14 can drive the main stirring rod 8 to rotate, and can also drive the main shaft 9 to rotate, so that the mixing cylinder 1 and the sanding cylinder 2 can work simultaneously.

[0028] See also Figure 3-4 In order to improve the stirring and mixing efficiency, a pair of auxiliary stirring rods 15 are rotatably installed in the mixing drum 1. The auxiliary stirring rods 15 are distributed on both sides of the main stirring rod 8, and one end of the auxiliary stirring rod 15 extending outside the mixing drum 1 is connected to a sub-gear 16. A main gear 17 is also installed on the outer wall of the main stirring rod 8, and the main gear 17 is meshed with the sub-gear 16. When the main stirring rod 8 rotates, the auxiliary stirring rods 15 on both sides can be driven to rotate in the opposite direction through the main gear 17 and the sub-gear 16, thereby improving the mixing efficiency.

[0029] See also Figure 1-4 In order to prevent the solution from splashing out during stirring or sanding, the upper ends of the raw material feed port 4 and the abrasive feed port 5 are both threadedly connected with a protective cover 18.

[0030] See also Figure 2 and Figure 4 In order to improve the working stability of the motor 14, the mixing drum 1 and the motor 14 are supported by a frame 19, and a stabilizing bar 20 is also installed on the frame 19. One end of the stabilizing bar 20 is connected to the main stirring rod 8 through a bearing to maintain the stability of the rotation of the main stirring rod 8.

[0031] See also Figure 3 In order to facilitate the separation of abrasive and suspended solution, a net basket 22 is placed in the collection box 7. The net basket 22 filters the solution and leaves the abrasive. The two sides of the net basket 22 are hung on the upper edge of the collection box 7 through hanging ears, so that the net basket 22 can be easily disassembled relative to the collection box 7.

[0032] See also Figure 3-4 In order to ensure that the mixing drum 1 and the sand milling drum 2 can simultaneously perform solution stirring and solution sand milling, a control valve 21 is installed on the connecting pipe 3 and the discharge port 6. When the control valve 21 is in the closed state, the mixing drum 1 can stir and mix the solution again while the solution sand milling is being performed in the sand milling drum 2.
