Description

Technical Field

[0001] The present invention relates to the technical field of pesticide formulation preparation, and specifically to a glyphosate isopropylamine aqueous solution preparation device and a preparation method thereof. Background Art

[0002] With the acceleration of the agricultural modernization process, the demand for efficient and environmentally friendly pesticide formulations is increasing day by day. As a widely used herbicide, the glyphosate isopropylamine aqueous solution, the advantages and disadvantages of its preparation technology directly affect product performance, production cost, and market competitiveness. In the current preparation field, there are many significant problems in the existing technologies and devices, which seriously restrict the development of the industry.

[0003] Specifically, the problems of the existing technologies are mainly reflected in the following aspects: The mixing effect is poor. The traditional stirring device has a simple design and regular stirring blade shapes. During the stirring process, only relatively gentle flows can be generated, and strong turbulence cannot be formed, resulting in the difficulty of fully mixing glyphosate, isopropylamine, and water. This leads to uneven distribution of the active ingredients in the product. In actual weed control applications, the drug efficacy is unstable, the weed control effect is poor in some areas, and weeds are prone to develop resistance, seriously affecting the market competitiveness of the product.

[0004] Secondly, the existing feeding system lacks a precise control mechanism and cannot add raw materials according to different raw material ratio requirements. During the production process, situations of excessive or insufficient raw material addition often occur, which not only causes waste of raw materials and increases production costs, but also affects the stability of product quality due to inaccurate ratios, and it is difficult to meet the market's demand for high-quality products.

[0005] Furthermore, due to the lack of effective cleaning and filtering measures, during the production process, raw materials are prone to adhere to the inner wall of the equipment. After long-term accumulation, it will cause equipment corrosion and increased wear, and frequent maintenance and component replacement are required. This not only increases the equipment maintenance cost, but also reduces the continuity and stability of production, affecting the production efficiency of the enterprise.

[0006] In summary, developing a glyphosate isopropylamine aqueous solution preparation device and method that can solve the above problems and achieve efficient, energy-saving, and precise control of the preparation process has important practical significance and economic value, and is also an urgent need to promote the development of the glyphosate isopropylamine aqueous solution industry. Summary of the Invention

[0007] Object of the Invention: The object of the present invention is to provide a glyphosate isopropylamine aqueous solution preparation device and a preparation method thereof to solve the problems in the existing technologies, such as uneven mixing, inability to perform secondary mixing on precipitated raw materials, resulting in waste of raw materials, inability to automatically supplement raw materials according to the ratio based on the mixing frequency, and secondly, it is not convenient to clean the inside of the device.

A stirring device is fixedly arranged on the inner wall of the housing, a cleaning device is arranged on the surface of the stirring device, a filter plate is arranged below the stirring device, a plurality of feeding devices are evenly arranged above the housing, a circulating device is fixedly arranged on one side above the housing, and a heat exchanger is arranged on the surface of the housing; A discharge port is opened below the housing; The stirring device includes a stirring motor installed above the housing. A stirring rod is adaptively arranged at the output end of the stirring motor. A stirring cross is fixedly arranged below the stirring rod. Stirring blades are fixedly arranged below the endpoints of the stirring cross. A stirring reciprocating screw rod is fixedly arranged below the stirring cross. A limiting shaft is movably arranged below the stirring reciprocating screw rod. A cross fixing plate is fixedly arranged below the limiting shaft. The cross fixing plate is fixedly installed on the lower inner wall of the housing. A first gear is fixedly arranged at the upper end of the stirring rod. A plurality of second gears fixedly connected to the stirring rod are evenly arranged below the first gear; The filter plate is in threaded fit connection with the stirring reciprocating screw rod.

[0009] Furthermore, the cleaning device includes a plurality of cleaning shafts evenly installed on the surface of the stirring rod. A plurality of cleaning rods are evenly arranged on the side of the cleaning shaft. A cleaning scraper is fixedly arranged at one end of the cleaning rod. The cleaning scraper is in contact with the inner wall of the housing.

[0010] Furthermore, the feeding device includes a plurality of feeding cylinders evenly installed above the housing, and also includes a feeding plate fixedly installed at one end of the inner wall of the housing. A feeding gear is movably arranged above the feeding plate. A feeding belt is adaptively arranged on the surface of the feeding gear. One end of the feeding belt is in fit connection with the second gear. A feeding reciprocating screw rod is fixedly arranged above the feeding gear. A feeding slider is in threaded fit connection with the surface of the feeding reciprocating screw rod. The feeding slider is in movable fit with the inner wall of the feeding cylinder.

[0011] Furthermore, the lengths of the feeding sliders in a plurality of feeding cylinders are all different.

[0012] Furthermore, the circulating device includes an absorption tower fixedly installed above the housing. A circulating plate is fixedly arranged below the absorption tower. A circulating gear is fixedly arranged above the middle of the circulating plate. A circulating belt is adaptively arranged on the surface of the circulating gear. The circulating belt is in fit connection with the first gear. A circulating fan blade is fixedly arranged above the circulating gear. A filter screen is fixedly arranged on the inner wall of the absorption tower. A circulating pipe is fixedly arranged on one side above the absorption tower. A circulating distribution ring is arranged at one end of the circulating pipe. The circulating distribution ring is fixedly installed at the discharge port. A plurality of circulating air pipes are evenly arranged above the circulating distribution ring. The circulating air pipes penetrate and extend into the lower inner wall of the housing.

[0013] Furthermore, a small-scale cold and heat circulation machine is fixedly arranged on the surface of the circulating pipe.

[0014] Further, a preparation method of a glyphosate isopropylamine aqueous solution preparation device includes the following steps: S1: Connect the three feed cylinders above the housing to the glyphosate, isopropylamine, and water raw material tanks respectively, and connect the feed cylinders with different feed slider lengths according to the preset ratio; S2: Start the stirring motor to drive the stirring rod and its connecting components to rotate. The stirring blades stir the raw materials, and their irregular design enhances the mixing effect; the stirring reciprocating screw drives the filter plate to move up and down, bringing the unmixed raw materials on the filter plate into the stirring area to be redissolved; S3: The stirring rod drives the second gear, and the feed gear rotates through the feed belt, driving the feed reciprocating screw to move the feed slider up and down. The slider enters the feed cylinder to block the feed. After rotating a certain number of turns, the slider disengages from the feed cylinder to supplement the raw materials. The speed difference generated by the size difference between the feed gear and the second gear ensures that the raw materials have enough time to mix, and different lengths of feed sliders meet different ratio requirements; S4: The stirring rod drives the first gear, and the circulating gear rotates at a high speed through the circulating belt, driving the circulating fan blades to discharge the gas in the housing into the absorption tower. After filtration, it circulates through the circulating pipe. In the circulating pipe, the temperature of the gas is adjusted by a small-scale cold and hot circulating machine. The adjusted gas enters the housing, generating bubbles to enhance the mixing effect and adjusting the temperature of the mixture in the housing; S5: After completing the above steps, open the discharge port to collect the prepared glyphosate isopropylamine aqueous solution.

[0015] The beneficial effects of this technical solution are: (1) The stirring motor drives the stirring rod to rotate, and then the irregularly designed stirring blades and stirring cross are coordinated to operate. The unique shape of the stirring blades generates strong turbulence during rotation, breaking the diffusion resistance between the raw materials, allowing glyphosate, isopropylamine, and water to come into full contact and blend in a short time, greatly improving the uniformity of mixing. This makes the active ingredients in the final product evenly distributed, and during actual weeding operations, it can stably and efficiently exert the weeding effect, effectively reducing the generation of weed resistance and improving the thoroughness of weeding; The filter plate works in coordination with the stirring device to filter the mixed liquid in real time during the stirring process, eliminating the need for a separate filtering process after mixing, simplifying the production process, saving production time and equipment costs. At the same time, the filter plate brings the unmixed precipitated raw materials back to the stirring area for re-mixing, reducing the cleaning difficulty caused by the deposition of raw materials at the bottom of the equipment and further improving production efficiency.

[0016] (2) The second gear drives the feeding gear, causing the feeding reciprocating lead screw to control the up and down movement of the feeding slider. This design can accurately control the timing and amount of raw material addition. When the feeding slider blocks the feeding cylinder, the raw materials in the shell are fully mixed; when the slider moves downward and disengages from the feeding cylinder, raw materials can be replenished in a timely manner. Feeding sliders of different lengths can also adapt to various ratio requirements, ensuring that each raw material can accurately enter the reaction system according to the preset ratio, avoiding waste of raw materials, reducing production costs, and at the same time ensuring the stability of product quality.

[0017] (3) The rotation of the stirring rod drives the circulating fan blades to rotate at high speed through gear transmission, pumping the gas in the shell to the absorption tower for filtration and then circulating it back to the shell. During the circulation process, the small-scale cold and hot circulation machine precisely adjusts the gas temperature. The adjusted gas enters the shell to generate bubbles and promote mixing, while also realizing the temperature control of the reaction mixture. In this process, the gas is recycled, avoiding additional heating or cooling energy consumption, achieving efficient use of energy, reducing the energy cost in the production process, and conforming to the concept of sustainable development.

[0018] (4) When the stirring rod rotates, the cleaning shaft, cleaning rod, and cleaning scraper operate synchronously to timely remove the raw materials adhering to the inner wall of the shell. This not only ensures the cleanliness of the reaction environment but also avoids corrosion and wear of the equipment caused by the accumulation of raw material residues, effectively extending the service life of the equipment, reducing the maintenance frequency and repair cost of the equipment, and improving the continuity and stability of production.

[0019] (5) Whether it is the production of conventional glyphosate isopropylamine salt aqueous solution or the adjustment of raw material ratio for special requirements, this device and method can easily handle it. By replacing the feeding cylinder with feeding sliders of different lengths, it can quickly adapt to the new raw material ratio without large-scale modification of the equipment, providing strong support for enterprises to quickly respond to market demands and develop new products, and enhancing the competitiveness of enterprises in the market.

A circulation device 9 is fixedly installed on one side above the housing 1, and the circulation device 9 is used to recycle the gas in the reaction process and adjust the temperature. The circulation device 9 includes an absorption tower 901 fixedly installed above the housing 1. A circulation plate 902 is fixedly installed below the absorption tower 901. A circulation gear 903 is fixedly installed above the middle of the circulation plate 902. A circulation belt 904 is adaptively installed on the surface of the circulation gear 903. The circulation belt 904 is adaptively connected to the first gear 308. A circulation fan blade 905 is fixedly installed above the circulation gear 903,A filter screen 906 is fixedly installed on the inner wall of the absorption tower 901. On one side above the absorption tower 901, a circulation pipe 907 is fixedly installed. A small-scale cold and hot circulation machine 7 is fixedly installed on the surface of the circulation pipe 907, which can adjust the temperature of the circulating gas, and thus control the temperature of the reaction mixture in the housing 1. One end of the circulation pipe 907 is installed with a circulation distribution ring 908. The circulation distribution ring 908 is fixedly installed at the discharge port 101. A number of circulation gas pipes 909 are evenly installed above the circulation distribution ring 908. The circulation gas pipes 909 penetrate and extend into the lower part of the inner wall of the housing 1. A heat exchanger 8 is installed on the surface of the housing 1. The heat exchanger 8 assists in adjusting the reaction temperature; A preparation method of a glyphosate isopropylamine aqueous solution preparation device includes the following steps: S1: According to the preset ratios of glyphosate, isopropylamine, and water, the three feeding cylinders 606 at the top of the housing 1 are respectively connected to the raw material storage tanks of glyphosate, isopropylamine, and water. At the same time, according to different ratio requirements, the feeding cylinders 606 equipped with feeding sliders 605 of different lengths are selected for assembly; S2: With the aid of the control device, the stirring motor 301 is started. The motor operation drives the stirring rod 302 to rotate at a high speed, and then drives the stirring cross 303, the first gear 308, and the second gear 309 to rotate in coordination. The stirring cross 303 drives the stirring blades 304 and the stirring reciprocating lead screw 305 to rotate synchronously. Due to the unique irregular shape design of the stirring blades 304, strong turbulence is generated during the stirring process, greatly improving the mixing effect. The rotation of the stirring reciprocating lead screw 305 drives the filter plate 5 to move up and down along the lead screw. When the filter plate 5 moves up to the top of the lead screw and then starts to move down, during this process, the precipitated raw materials that are not fully mixed on the surface of the filter plate 5 can be brought to the central area of the housing 1, that is, the position close to the stirring blades 304, to achieve secondary mixing and dissolution, effectively reducing raw material waste; S3: The continuous rotation of the stirring rod 302 drives the second gear 309 to rotate synchronously. The second gear 309 drives the feeding gear 602 to rotate through the feeding belt 603. The feeding gear 602 drives the feeding reciprocating lead screw 604 to rotate, and then the feeding slider 605 moves up and down in the feeding cylinder 606. When the feeding slider 605 moves up to the inside of the feeding cylinder 606, the feeding channel is completely blocked, and the raw materials stop entering the housing 1. At this time, the raw materials in the housing 1 can be fully mixed under the stirring action. As the feeding reciprocating lead screw 604 continues to rotate, after a specific number of turns, the feeding slider 605 moves down to the bottom of the feeding cylinder 606 and disengages, and the feeding cylinder 606 is reopened to supplement raw materials into the housing 1 and continue the mixing reaction. Since the diameter of the feeding gear 602 is larger than that of the second gear 309, there is a difference in their rotation speeds, which ensures that there is sufficient time for the raw materials in the housing 1 to be fully mixed. At the same time, the feeding sliders 605 of different lengths can achieve precise and synchronous supply of each raw material according to different raw material ratios; S4: The rotation of the stirring rod 302 drives the first gear 308 to rotate. The first gear 308 drives the circulating gear 903 to rotate at high speed through the circulating belt 904. Since the size of the first gear 308 is larger than that of the circulating gear 903, the rotation speed of the circulating gear 903 is higher than that of the first gear 308. The circulating gear 903 drives the circulating fan blade 905 to rotate rapidly, sucking the gas in the housing 1 into the absorption tower 901. After the gas is filtered by the filter screen 906 in the absorption tower 901, it returns through the circulating pipe 907. In the circulating pipe 907, by adjusting the working parameters of the small-scale cold and hot circulating machine 7, the temperature of the circulating gas is adjusted. The adjusted gas is discharged to the bottom of the housing 1 through the circulating distribution ring 908 and the circulating gas pipe 909, generating a large number of tiny bubbles in the liquid in the housing 1, which not only further enhances the mixing effect but also significantly reduces energy consumption. At the same time, by using the small-scale cold and hot circulating machine 7 to raise and lower the temperature of the circulating gas, the temperature of the reaction mixture in the housing 1 is accurately controlled to ensure that the reaction proceeds under suitable temperature conditions; S5: After the above series of processes of sufficient mixing, filtering, and temperature adjustment, the discharge port 101 is opened, and the prepared glyphosate isopropylamine salt aqueous solution meeting the quality standards is collected and stored.

[0024] Working principle: After the stirring motor 301 is powered on and starts, it converts electrical energy into mechanical energy to drive the stirring rod 302 to rotate. The stirring cross 303 and the stirring blade 304 rotate synchronously with the stirring rod 302. The irregular shape of the stirring blade 304 forms a complex turbulent flow field in the housing 1, increasing the collision and mixing opportunities between the materials. The stirring reciprocating lead screw 305 rotates synchronously. Using the principle of screw drive, the filter plate 5 threadedly and adaptively connected to it moves up and down along the lead screw, thereby bringing the precipitated raw materials on the surface of the filter plate 5 to the stirring center area to achieve secondary mixing; The rotation of the stirring rod 302 drives the second gear 309 to rotate. Through the transmission of the feeding belt 603, the feeding gear 602 rotates. The feeding gear 602 drives the feeding reciprocating lead screw 604 to rotate. Using the principle of lead screw-nut drive, the feeding slider 605 moves up and down in the feeding cylinder 606. When the feeding slider 605 moves upward to block the feeding channel, the raw materials stop entering; when it moves downward and disengages, the feeding cylinder 606 starts feeding. The feeding sliders 605 with different lengths have different strokes in the feeding cylinder 606, so as to achieve accurate feeding of different raw materials in proportion; The stirring rod 302 drives the first gear 308 to rotate. Through the circulating belt 904, the circulating gear 903 rotates at a high speed, driving the circulating fan blade 905 to rotate. Using the centrifugal force principle, the gas in the housing 1 is sucked into the absorption tower 901. After the gas is filtered by the filter screen 906 in the absorption tower 901, it enters the circulating pipe 907. The small-scale cold and heat circulation machine 7 adjusts the temperature of the circulating gas through the refrigeration or heating principle. The adjusted gas enters the bottom of the housing 1 through the circulating distribution ring 908 and the circulating gas pipe 909. By using the interaction between the gas and the liquid, tiny bubbles are generated to enhance the mixing effect and at the same time adjust the reaction temperature.

[0025] The above are only embodiments of the present invention. Specific technical solutions or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.

In the circulating pipe, the gas temperature is adjusted by a small cold and hot circulation machine (7), and the adjusted gas enters the shell (1), generates bubbles to enhance the mixing effect and adjust the temperature of the mixture in the shell (1); S5: After completing the above steps, the discharge port (101) is opened to collect the prepared glyphosate isopropylamine salt solution.
