This utility model relates to the field of chemical equipment technology and discloses a mixing vessel for preparing a bactericide and algaecide solution. The vessel includes a tank body, with a transmission seat fixedly connected to the upper end of the tank body via multiple support rods. A mixing assembly is disposed between the tank body and the transmission seat. A waste gas purification assembly is disposed on one side of the tank body. The mixing assembly includes two lifting threaded rods, both rotatably connected to the transmission seat. The threads of the two lifting threaded rods are arranged in opposite directions. Lifting sleeves are threaded onto the outer walls of both lifting threaded rods. Lifting frames are fixedly connected to the lower ends of both lifting sleeves. A stirring motor is fixedly disposed inside each of the two lifting frames. In this utility model, by providing a mixing assembly, the two stirring rods can be staggered in their lifting and lowering, and combined with the rotation of the stirring rods, the stirring range is effectively expanded, forming a three-dimensional stirring trajectory, significantly improving the uniformity of the solution mixing and increasing the mixing efficiency.

An additive transporter, housing additive ingredients of synergists and surfactants preferably for use in a natural, weed control application, insect control application, algae removal and / or mold removal end-use application. In certain non-limiting embodiments, the transporter can be fluid soluble. Where the transporter is fluid soluble it can be added to a container / bottle having a desired amount of water and organic acid or inorganic acid causing the transporter to dissolve and release the additive ingredients for mixing with the water and organic acid. Preferably, the additive or product enhancer ingredients can be organic ingredients and can comprise, without limitation, citric acid, potassium oleate, wintergreen oil and almond oil. Potassium citrate can also be included. As the transporter dissolves the released ingredients mix with organic acids and / or inorganic acids to provide an end-use composition for eco-friendly weed control, insect control, algae removal and / or mold removal. Though not considered limiting, the transporter can be in the form of a pod, packet, pouch, capsule, carton, or cardboard / plastic / metal container.

This application relates to a raw material mixing device for the production of bactericides and algaecides, belonging to the technical field of mixing equipment. It includes a mixing tank, a mixing shaft, mixing blades, and a reduction drive motor. A feeding assembly is installed at the top of the mixing tank, and multiple flow-dispersing components are also installed inside the tank. These components include a rotating body, gears, racks, and an electric push rod. The rotating body is rotatably mounted inside the mixing tank. By incorporating these flow-dispersing components, in the early stages of mixing, the inclined surface of the flow-dispersing section faces the direction of the raw material's movement, allowing the raw material to flow quickly over the inclined surface, enabling rapid circulation. During this process, vortices are also formed behind the flow-dispersing components, providing initial turbulence and mixing. In the later stages of mixing, the electric push rod drives the rotating body to change direction, obstructing the flow of raw material and causing disorder within the mixing tank, thus ensuring thorough mixing and a good mixing effect.

This invention discloses an ecological slow-release algaecide and its preparation method, relating to the field of water treatment technology. The algaecide comprises 30%-50% copper oxychloride, 5%-50% basic copper carbonate, 5%-50% copper hydroxide, 5%-50% copper oxalate, 8%-12% copper sulfate pentahydrate, 2%-8% calcium sulfate dihydrate, 2%-8% oxalic acid dihydrate, 9%-18% pregelatinized starch, and 1.5%-2% magnesium stearate. The preparation method includes: weighing and mixing the components; pulverizing the mixed powder, sieving, and drying in an oven; and pressing the dried powder into tablets. This invention features a simple preparation process and low raw material costs. The algaecide of this invention has stable and long-lasting release, effectively reducing the frequency of algaecide application, and ensuring that the copper ion concentration in the water does not exceed the standard, greatly reducing the risk of water pollution caused by excessive algaecide application, while also reducing the labor costs associated with long-term algaecide application.

The application (named: a class of diaminobenzoquinone derivatives, preparation and algaecidal purposes thereof) relates to 29 kinds of diaminobenzoquinone derivatives, a preparation method thereof, and an algaecidal purpose. 2-acetylamino-5-substituted amino-p-benzoquinone is prepared by oxidation and amination of 2-acetylamino-1,4-dimethoxybenzene; 2-benzyloxycarbonylamino-5-substituted amino-p-benzoquinone is prepared by benzyloxycarbonylation, oxidation and amination of 2-amino-1,4-dimethoxybenzene. The compounds can be used as algaecides to prevent and control cladophora and microcystis aeruginosa.
