Description

Technical Field

[0001] The utility model relates to the field of pesticide batching devices, in particular to a batching device for emulsifiable concentrate production. Background Art

[0002] EC is one of the basic formulations of pesticides. It is a homogeneous transparent oily liquid made by dissolving the original pesticide (crude oil or original powder) in an organic solvent (such as xylene, toluene, etc.) in a specified proportion and then adding a certain amount of special emulsifier for pesticides.

[0003] When producing emulsifiable concentrate pesticides, it is necessary to mix the pesticide original, organic solvent and emulsifier in proportion. When preparing, it is necessary to ensure the mixing ratio between the raw materials, and then add the prepared raw materials into a stirring device for stirring. For example, a batching device for emulsifiable concentrate production in China with a patent number of CN 211537538 U uses a stirring barrel to mix and stir the raw materials. When adding raw materials, different raw materials are often put into the stirring device and stirred together. When placing different raw materials, due to stratification between different raw materials, it takes a long time to stir them evenly. Utility Model Content

[0004] The utility model aims to provide a batching device for emulsifiable concentrate production to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a batching device for emulsifiable concentrate production, comprising a plurality of raw material tanks for storing raw materials, and a pipeline is installed at the bottom of the raw material tank;

[0006] A pressure pump is installed at the end of the pipeline that contacts the raw material tank to provide the same pressure to the pipelines of multiple raw material tanks;

[0007] The valve is fixedly installed at the other end of the pipeline to control the flow of liquid in the pipeline;

[0008] A premixing tube is fixedly installed at one end of the pipeline away from the raw material tank. Raw materials from multiple raw material tanks flow into the premixing tube through the pipeline for premixing and are discharged from the discharge port of the mixing tube.

[0009] Preferably, a flow guiding component is provided inside the premixing tube to guide and mix the liquid entering the premixing tube.

[0010] Preferably, the flow guide component is a conical cylinder, the axis of the conical cylinder coincides with the axis of the premixing tube, a support rod is fixedly mounted on the outer side of the conical cylinder, and the support rod is fixedly connected to the inner side wall of the premixing tube.

[0011] Preferably, the flow guide component is a hemispherical flow guide cover, and a mounting shaft is integrally welded to the hemispherical flow guide cover. The mounting shaft is fixedly connected to the inner wall of the premixing tube through a fixing rod, and an impeller is rotatably mounted on the mounting shaft.

[0012] Preferably, a discharge pipe is provided at one end of the premixing tube away from the pipeline, and a tapered tube is provided between the discharge pipe and the premixing tube.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model arranges a pressure pump, a pipeline and a valve on each raw material tank. The pressure pump provides the same pressure to each pipeline, and the valve can adjust the flow of the pipeline. Since the pipeline pressure remains unchanged, the flow of the pipeline can be changed by adjusting the valve, which is very convenient for adjusting the flow.

[0015] By setting up a pressure pump, the flow rate of the pipeline can be adjusted according to the ratio of the pesticide. In the same period of time, the flow ratio of each pipeline is guaranteed to remain the same as the pesticide ratio. When the raw materials in the pipeline flow into the pre-mixing tube, the pesticide raw materials can be pre-mixed in the pre-mixing tube. After the pre-mixed raw materials are discharged into the stirring device, no stratification will occur. During stirring, the stirring time can be shortened and the mixing effect of the raw materials is also better. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As shown in the figure, this embodiment provides a batching device for emulsifiable concentrate production, including a plurality of discharge tanks 1, such as a pesticide original drug tank, an emulsifier tank and a solvent tank. The original drug tank is used to place liquid original drugs.

[0024] The emulsifier in the emulsifier tank is mostly a mixture of nonionic and anionic surfactants, such as the common dimannan biphenyl polyoxyethylene ether nonionic emulsifier or calcium dodecylbenzene sulfonate anionic emulsifier and dispersant and other commonly used pesticide emulsifiers.

[0025] The solvent tank may contain petroleum solvents such as xylene and methylnaphthalene, or alcohol solvents such as methyl isobutyl ketone and isopropyl alcohol.

[0026] A pipeline 4 is fixedly installed at the bottom of the raw material tank 1, and a pressure pump 2 is fixedly installed at one end of the pipeline 4 close to the raw material tank 1. The pressure pump 2 provides the same pressure to the pipeline of each raw material tank 1. A valve 3 is installed at one end of the pipeline 4 away from the raw material tank 1, and the opening size of the valve 3 is used to control the flow rate of the liquid in the pipeline.

[0027] A premixing tube 5 is fixedly installed at one end of the pipeline 4 away from the raw material tank 1, and the diameter of the premixing tube 5 is larger than the diameter of the pipeline 4. A discharge port is provided at one end of the premixing tube 5 away from the pipeline 4, and a discharge pipe is fixedly installed on the discharge port. Raw materials from multiple raw material tanks 1 flow into the premixing tube 5 through the pipeline 4 for premixing, and are discharged from the discharge pipe of the premixing tube 5 to the mixing tank for mixing and stirring (this part is not shown in the figure).

[0028] In a further embodiment, an end of the premixing tube 5 away from the pipeline 4 is provided with an opening structure, and a tapered tube is provided between the opening structure and the discharge tube. When the liquid flows out of the premixing tube 5, it can flow directly into the discharge tube under the guidance of the tapered tube.

[0029] When controlling the raw materials to enter the premixing tube 5, for liquids with a relatively large demand for raw materials (such as solvents), the valve 3 on the pipeline 4 can be opened relatively wide, so that the liquid flows into the premixing tube 5 relatively quickly. For liquids with a relatively small demand (such as emulsifiers), the valve on the pipeline 4 of the raw material tank is opened relatively small, so that the flow rate of the liquid is relatively slow, so that all the raw materials stop flowing almost at the same time. During the flow of the raw materials, they will be mixed in the premixing tube 5. Compared with putting the raw materials into the mixing tank one by one, the dispersion effect of the pesticide is better when the premixed raw materials are stirred.

[0030] In this embodiment, a pressure pump 2 is provided on each pipeline 4, and the pressure pump 2 provides the same pressure to each pipeline 4. When adjusting the flow rate of the pipeline 4, since the pressure at one end of the pipeline 4 is the same, it is only necessary to adjust the opening size of the valve 3 to control the flow rate in the pipeline 4, which is very convenient for controlling the flow speed of the liquid in the pipeline 4 (ignoring the viscosity of the liquid).

[0031] Take 40% dimethoate EC pesticide as an example: dimethoate technical 40%, pesticide emulsifier (Agricultural Emulsion 0204C) 6%, mixed benzene 54%. Taking the preparation of 100L of pesticide as an example, the required technical is 40L, concentrated emulsion is 6L, and mixed benzene is 54L.

[0032] According to the empirical formula: Q = πR^2√2P / ρ

[0033] In the formula, Q is the flow rate, R is the pipe radius, P is the pressure, and ρ is the liquid density.

[0034] Mixed benzene, agricultural emulsion 0204C and dimethoate technical are all organic solvents with similar densities, which can be approximately the same. The influence of density is ignored here.

[0035] Therefore, when configuring 100L of pesticide, ensure that the mixed benzene, agricultural emulsion 0204C, and dimethoate technical flow in the pipeline for the same time, which is S. Within the time S, the total flow is QS, and the total flow is directly related to the radius R.

[0036] The total flow ratio of mixed benzene, agricultural emulsion 0204C and dimethoate technical is 54:6:40, that is, the square ratio of the radius of the valve adjustment on the pipeline is 54:6:40. The size of the valve can be adjusted according to this ratio. In the same time, the raw materials entering the pre-mixing pipe 5 are all in the specified ratio.

[0037] like Figure 1 and Figure 2As shown, there are three raw material tanks 1, and the raw material tank in the middle is used to hold the raw material with the largest demand, such as solvent. The pipeline 4 of the raw material tank in the middle is connected to the center of one end of the premixing tube 5, and the pipelines 4 of the other two raw material tanks are respectively connected to the side of the premixing tube 5 and extend into the inner cavity of the premixing tube 5, as shown in FIG. Figure 2 When the solvent enters the premixing tube 5 from the pipeline 4, its flow rate and flow velocity are relatively fast. When the liquids in other pipelines enter the premixing tube 5, the other liquids can be better mixed with the solvent raw material.

[0038] In order to improve the mixing effect of the raw materials in the premixing tube and avoid the stratification of the liquid, a flow guide component is provided inside the premixing tube 5 to guide and mix the liquid entering the premixing tube 5. Figure 2 and Figure 3 As shown, the flow guide component is a conical cylinder 6, the axis of which coincides with the axis of the premixing tube 5, a support rod 7 is fixedly installed on the outer side of the conical cylinder 6, and the support rod 7 is fixedly connected to the inner wall of the premixing tube 5. When the liquid enters the premixing tube 5, the liquid flows through the conical cylinder 6 to both sides, which can make the liquid better mixed.

[0039] like Figure 4 and Figure 5 As shown, the flow guide component can also be set as a hemispherical flow guide cover 8, the flow guide cover 8 is integrally welded with a mounting shaft, a fixing rod is welded on the outside of the mounting shaft, the other end of the fixing rod is fixedly connected to the inner wall of the premixing tube 5, and an impeller 9 is rotatably mounted on the mounting shaft. When the liquid flows through the hemispherical flow guide cover 8, it will flow to the side of the hemispherical flow guide cover 8, and the liquid will pass through the impeller 9. The impeller 9 will rotate around the mounting shaft under the flushing of the fluid to better mix the pesticide raw materials. Even if the impeller 9 does not rotate, the liquid will mix when it flows through the space between the blades of the impeller 9.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
