Description

Technical Field

[0001] The utility model relates to the technical field of humic acid activation, in particular to a high-efficiency activation reaction device. Background Art

[0002] Humic acid is a type of high molecular weight organic substance formed by plant residues through microbial decomposition and chemical reactions, and has good biological activity, adsorption, ion exchange, flocculation and other properties. However, the activity of humic acid is affected by its own structure, chemical composition, physical form and other factors, resulting in limited application effects.

[0003] Chinese patent application CN218902975U was published on April 25, 2023. A rapid activation and cleaning device is disclosed. The rapid activation and cleaning device comprises an activation kettle, an anchor-type stirring paddle driven by a stirring motor is provided inside the activation kettle, a U-shaped feeder is provided on the outside of the anchor-type stirring paddle, a heating device is provided on the outside of the activation kettle, and an obtuse-angle discharge port is provided at the bottom of the activation kettle. However, in production, the activation time has not been significantly shortened, and the U-shaped feeder has not been able to solve the problem of improving the mixing efficiency of solid-phase materials and acid solution.

[0004] In summary, the existing device has problems of long activation time and low mixing efficiency of solid phase and acid solution in workshop production, which greatly affects the production progress. Utility Model Content

[0005] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a high-efficiency activation reaction device. Through the setting of a premixing kettle, the used low-concentration acid solution is introduced into the premixing tank for premixing with the solid phase. While improving the utilization efficiency of the acid solution, the solid phase is also preactivated, which greatly improves the activation efficiency of the activation kettle; through the setting of an inclined connecting pipe and a filter, the acid solution in the premixing kettle is filtered into a waste acid solution collection tank, thereby avoiding the influence of the acid solution in the premixing kettle on the activation of the acid solution in the activation kettle; through the setting of the activation kettle feed port and the hemispherical disperser, the material falls freely to the arc surface of the hemispherical disperser by gravity, and the material is evenly dispersed in the premixing kettle. Combined with the spray plate, the mixing efficiency of the solid phase and the acid solution is greatly improved, and the activation time is reduced.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] The high-efficiency activation reaction device comprises an activation kettle and a premixing kettle. The premixing kettle is connected to the activation kettle through an inclined connecting pipe. A hemispherical disperser and a spray plate are arranged inside the activation kettle. A filter is arranged below the inclined connecting pipe. The filter is connected to a waste acid liquid collection tank through a connecting pipe.

[0008] The premixing kettle is used to premix humic acid and used low-concentration acid liquid. The used low-concentration acid liquid comes from the acid liquid filtered out after activation in the activation kettle. The materials in the inclined connecting pipe slide into the activation kettle by gravity. The preactivated materials fall freely from the activation kettle feed port to the surface of the hemispherical disperser. After being dispersed on the surface, they are mixed with the acid liquid sprayed from the spray plate.

[0009] A stirring paddle driven by a stirring motor is arranged inside the activation kettle, and an obtuse-angle discharger is arranged below the activation kettle.

[0010] The activation kettle is provided with an activation kettle feed port, a hemispherical disperser is located directly below the activation kettle feed port, and a spray plate is located below the hemispherical disperser.

[0011] The inclined connecting pipeline is connected to the activation kettle through the activation kettle feed port, and the waste acid liquid collecting tank is provided with a waste acid liquid discharge port.

[0012] The interior of the premixing kettle is provided with a stirrer, and the premixing kettle is provided with a solid phase feed port and a return acid liquid inlet pipeline.

[0013] The spray plate is connected with an acid liquid inlet pipeline, and the filter is provided with a filter net.

[0014] The working principle of the utility model is:

[0015] Humic acid enters the premixing kettle through the solid phase feed port, and the used low-concentration acid enters the premixing kettle through the return acid entering pipe. The agitator starts working. After the premixing is completed, the material enters the inclined connecting pipe; when the material passes through the inclined connecting pipe, the liquid phase in the material falls into the waste acid collection tank through the filter for collection, and the solid phase after solid-liquid separation enters the activation kettle; after the premixed material passes through the activation kettle feed port, the material falls freely by gravity to the arc surface of the hemispherical disperser, and the material is evenly dispersed in the premixing kettle. The stirring motor drives the stirring paddle to start working, and the acid is sprayed into the activation kettle through the spray plate to activate the humic acid. Among them, the premixing kettle is used to premix humic acid and used low-concentration acid. The used low-concentration acid comes from the acid filtered out after the activation is completed in the activation kettle. The material in the inclined connecting pipe slides into the activation kettle by gravity. The pre-activated material freely falls from the activation kettle feed port to the surface of the hemispherical disperser, and after being dispersed on the surface, it mixes with the acid sprayed from the spray plate. The activation time of humic acid in the activation kettle can be used to pre-mix the material.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By adopting the high-efficiency activation reaction device of the utility model, through the setting of the premixing kettle, the used low-concentration acid liquid is introduced into the premixing tank for premixing with the solid phase, so that the utilization efficiency of the acid liquid is improved and the solid phase is preactivated, which greatly improves the activation efficiency of the activation kettle; through the setting of the inclined connecting pipe and the filter, the acid liquid in the premixing kettle is filtered into the waste acid liquid collection tank, thereby avoiding the influence of the acid liquid in the premixing kettle on the activation of the acid liquid in the activation kettle; through the setting of the activation kettle feed port and the hemispherical disperser, the material falls freely to the arc surface of the hemispherical disperser by gravity, and the material is evenly dispersed in the premixing kettle. Combined with the spray plate, the mixing efficiency of the solid phase and the acid liquid is greatly improved, and the activation time is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
