Description

Technical Field

[0001] This utility model relates to the field of herbicide production technology, and in particular to a concentration mixing device for herbicide production. Background Technology

[0002] In modern agricultural production, the widespread use of herbicides has effectively improved crop planting efficiency. However, the accuracy of herbicide concentration preparation directly affects its weeding efficacy and safety. Currently, most herbicide concentration preparation relies on manual operation or simple mechanical devices, involving manual measurement and mixing of the active ingredient. This method is not only inefficient but also makes it difficult to accurately control the proportions of each active ingredient, resulting in significant errors in the prepared herbicide concentration and affecting its effectiveness.

[0003] Meanwhile, herbicide technical materials are mostly chemically synthesized substances, which easily volatilize and produce harmful gases during the mixing process. Traditional mixing equipment lacks an effective mechanism for collecting and treating these harmful gases, which are directly emitted into the production environment, endangering not only the health of operators but also potentially causing environmental pollution. Although some equipment is equipped with simple ventilation systems, they cannot effectively intercept and purify the toxic substances in the harmful gases, resulting in limited treatment effectiveness. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a concentration mixing device for herbicide production, which solves the problem that the mixing device lacks an effective mechanism for collecting and treating harmful gases, resulting in the direct emission of volatile harmful gases into the production environment and causing environmental pollution.

[0005] This utility model also provides a concentration mixing device for herbicide production, comprising: a base, a cylinder and a support fixedly connected to the upper surface of the base, three measuring cylinders and a metering pump fixedly connected inside the support, the input ends of the three metering pumps being sequentially and fixedly connected to the three measuring cylinders, and the output ends of the metering pumps being fixedly connected to the cylinder through a delivery pipe; a motor fixedly connected to the side surface of the cylinder, a stirring shaft fixedly connected to the output end of the motor, an exhaust valve fixedly connected to the outside of the cylinder, and a collection box fixedly connected to the outlet of the exhaust valve through an exhaust pipe, the lower surface of the collection box being fixedly connected to the base, and a filter and a negative pressure fan fixedly connected to the upper surface of the base, the exhaust port of the negative pressure fan being fixedly connected to the collection box, and the outlet of the collection box being fixedly connected to the filter. The three metering pumps respectively extract the raw material from the corresponding measuring cylinder and deliver it to the cylinder according to a preset ratio, ensuring precise and controllable pesticide concentration. In addition, the negative pressure fan extracts gas from the collection box; harmful gases volatilized during the mixing process are introduced into the collection box through the exhaust valve and effectively intercepted by the filter.

[0006] According to the herbicide production concentration mixing device of this utility model, the end of the stirring shaft away from the motor is rotatably connected to the inner wall of the cylinder, and the stirring shaft is located inside the cylinder. The cylinder provides rotational support to the end of the stirring shaft to prevent the stirring shaft from collapsing.

[0007] According to the herbicide production concentration mixing device of this utility model, the collection box is provided with multiple activated carbon adsorption layers, which are linearly distributed.

[0008] According to the herbicide production concentration mixing device of this utility model, the top of the measuring cylinder is fixedly connected to a feed inlet, and the cross-section of the feed inlet is a bucket structure that gradually decreases from top to bottom.

[0009] According to the herbicide production concentration mixing device of this utility model, a buffer pad is fixedly connected to the upper surface of the base, and the interior of the buffer pad is fixedly connected to the cylinder. The buffer pad is usually made of elastic materials such as rubber, which can effectively absorb the vibration energy generated by the cylinder during stirring, reduce noise pollution, and reduce the transmission of vibration to the base.

[0010] According to the herbicide production concentration mixing device of this utility model, the outlet of the filter is fixedly connected to a gas collection box, and the lower surface of the gas collection box is fixedly connected to a base. The gas collection box, as the final gas treatment unit after the filter, can temporarily store and perform secondary sedimentation of the purified waste gas, further separating any potentially residual fine particulate matter.

[0011] According to the herbicide production concentration mixing device of this utility model, the outer side of the cylinder is provided with a discharge port, and a liquid outlet valve is provided at the connection between the discharge port and the cylinder. The liquid outlet valve can precisely control the outflow rate of the herbicide solution by adjusting its opening degree.

[0012] According to the herbicide production concentration mixing device of this utility model, the lower surface of the base is provided with four casters, and brake pads are provided on the outside of the four casters. The casters enable the device to move, and the brake pads provide braking.

[0013] Beneficial effects: Compared with existing technologies, this new type of herbicide concentration mixing device has three metering pumps that draw raw materials from corresponding measuring cylinders and deliver them to the cylinders according to preset ratios, ensuring that the concentration of the herbicide is accurate and controllable.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model provides a concentration mixing device for herbicide production, comprising: a base 1, a cylinder 2 and a support 3 fixedly connected to the upper surface of the base 1, three measuring cylinders 4 and a metering pump 5 fixedly connected inside the support 3, the input ends of the three metering pumps 5 and the three measuring cylinders 4 being fixedly connected to each other in sequence, the top of the measuring cylinder 4 being fixedly connected to a feed inlet 15, the cross-section of the feed inlet 15 being a bucket structure that gradually decreases from top to bottom, and the output end of the metering pump 5 being fixedly connected to the cylinder 2 through a conveying pipe 6;

[0023] Specifically, the measuring cylinder 4 is fixed by the bracket 3, and the delivery volume of the three measuring cylinders 4 is controlled by the independent metering pump 5, so that they enter the interior of the cylinder 2 through the delivery pipe 6. Thus, the proportion of each component can be precisely adjusted according to the needs to ensure the concentration ratio error.

[0024] A motor 7 is fixedly connected to the side surface of the cylinder 2. A stirring shaft 8 is fixedly connected to the output end of the motor 7. The end of the stirring shaft 8 away from the motor 7 is rotatably connected to the inner wall of the cylinder 2. The stirring shaft 8 is located inside the cylinder 2. An exhaust valve 9 is fixedly connected to the outside of the cylinder 2. The outlet of the exhaust valve 9 is fixedly connected to a collection box 11 through an exhaust pipe 10. Multiple activated carbon adsorption layers 14 are arranged inside the collection box 11. The multiple activated carbon adsorption layers 14 are linearly distributed. The lower surface of the collection box 11 is fixedly connected to the base 1. A filter 12 and a negative pressure fan 13 are fixedly connected to the upper surface of the base 1. The exhaust port of the negative pressure fan 13 is fixedly connected to the collection box 11. The outlet of the collection box 11 is fixedly connected to the filter 12. The outlet of the filter 12 is fixedly connected to a gas collection box 17. The lower surface of the gas collection box 17 is fixedly connected to the base 1.

[0025] Specifically, the electric motor 7 drives the stirring shaft 8 to rotate, and the materials in the cylinder 2 are forcibly mixed through mechanical transmission. The harmful gas discharged by the exhaust valve 9 is treated by the multi-layer activated carbon adsorption layer 14 in the collection box 11 to effectively remove volatile organic compounds. The negative pressure fan 13 actively sucks up the exhaust gas, improves the gas flow efficiency, and prevents the leakage of harmful gas. The filter 12 further intercepts particulate matter. Finally, the purified gas is temporarily stored in the gas collection box 17 to achieve emission standards.

[0026] A buffer pad 16 is fixedly connected to the upper surface of the base 1. The inside of the buffer pad 16 is fixedly connected to the cylinder 2. An outlet 18 is provided on the outside of the cylinder 2. A liquid outlet valve 19 is provided at the connection between the outlet 18 and the cylinder 2. Four casters 20 are provided on the lower surface of the base 1. Brake pads 21 are provided on the outside of the four casters 20.

[0027] Specifically, the buffer pad 16 can effectively absorb the vibration energy generated by the cylinder 2 during stirring, thereby reducing noise pollution. When it is necessary to take out the liquid after adjustment, the liquid outlet valve 19 is opened so that the prepared herbicide can flow out from the outlet 18.

[0028] Working principle: First, the formulation is fed into the measuring cylinder 4 through the feed inlet 15. Then, three metering pumps 5 extract the formulation from the corresponding measuring cylinder 4 and deliver it to the cylinder 2 according to the preset ratio to ensure accurate concentration of the agent. The metering pumps 5 adopt a piston or diaphragm structure, and the flow rate is accurately controlled by adjusting the stroke length or frequency. Then, the motor 7 is started to drive the stirring shaft 8 to rotate, so that the agent is fully mixed and uniform in the cylinder 2, avoiding sedimentation or stratification and improving the consistency of the formulation. The collection box 11 temporarily stores the harmful gases volatilized during the formulation process through the exhaust pipe 10. The multiple activated carbon adsorption layers 14 inside the collection box 11 are arranged linearly to form a multi-stage adsorption channel, which can intercept pesticide volatiles in the exhaust gas step by step. At the same time, the airflow generated by the negative pressure fan 13 forces the gas to the filter 12 for purification, avoiding direct emission and environmental pollution.
