Description

Technical Field

[0001] This utility model relates to the field of pesticide production technology, specifically to a mixing device for acetamiprid raw materials. Background Technology

[0002] The acetamiprid raw material proportioning device is a specially designed device for the precise mixing and formulation of raw materials required for acetamiprid production. It adopts advanced automated control technology and high-precision metering elements to ensure accurate proportioning of raw materials, thereby guaranteeing the stable quality and performance of acetamiprid products.

[0003] A search revealed a Chinese patent with publication number CN223127940U, which discloses a mixing device for acetamiprid raw materials. The device includes a main body with supporting legs, with a support plate fixedly connected between the legs. Using this mixing structure, after mixing the acetamiprid raw materials, a controller activates a temperature sensor and a servo motor. The servo motor drives a rotating shaft to rotate a stirring paddle, causing a scraper on the paddle to scrape off the raw materials adhering to the inner wall of the main body. Simultaneously, a stirring brush at the bottom stirs the bottom of the main body, floating the settled raw materials, thus achieving a uniform mixing effect. The rotating paddle also drives the temperature sensor to rotate, allowing the sensor to move omnidirectionally to detect the temperature inside the main body. When uneven temperature distribution is detected, the controller automatically adjusts the speed of the servo motor to ensure uniform heat transfer during stirring, avoiding inconsistent temperature distribution within the reactor.

[0004] However, existing technologies cannot achieve pre-dispersion when powder is fed. They usually adopt a simple direct drop or synchronous flow with liquid, which makes it easy for powder to quickly form a crust on the local liquid surface. The powder forms fish-eye-shaped clumps inside that are difficult to completely open through subsequent stirring, which seriously affects the uniformity and solubility of the final product and becomes a bottleneck to improving mixing quality and efficiency.

[0005] Therefore, based on the above-mentioned search and combined with existing technology, a formulation device for acetamiprid raw materials is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a formulation device for acetamiprid raw materials to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mixing device for acetamiprid raw materials includes a support and a mixing equipment body. The top surface of the mixing equipment body is provided with a sealing cover. Liquid feed pipe and powder feed pipe are respectively provided on both sides of the top surface of the sealing cover. A controller is fixedly installed on the side wall of the support. A spraying mechanism is provided on the bottom surface of the sealing cover.

[0009] Preferably, the spraying mechanism includes: a connecting column, which is fixedly installed on the bottom surface of the sealing cover and located on the bottom surface of the powder feed pipe outlet. The top surface of the connecting column has a feed port with the same diameter as the outlet diameter of the powder feed pipe.

[0010] Preferably, the spraying mechanism further includes: a connecting ring, which is fixedly installed on the inner wall of the connecting column; a cone is installed below the connecting ring via multiple sets of vibrating elements, the diameter of the cone being smaller than the diameter of the connecting ring; a conical dispersion disk is provided below the cone; a circular groove is formed on the top surface of the conical dispersion disk; and multiple leakage holes are formed on the outer surface of the conical dispersion disk. The spraying mechanism also includes a drive assembly.

[0011] Preferably, the driving component includes: a fixed column, which is fixedly installed on the bottom surface of the circular groove, and a protective shell II is fixedly installed on the bottom surface of the cone. A drive motor is fixedly installed inside the protective shell II. The output shaft of the drive motor is connected to the top surface of the fixed column. When the drive motor starts, the fixed column rotates synchronously, and the conical dispersion disk connected to the fixed column rotates synchronously.

[0012] Preferably, the vibrating component includes: a connecting rod, which is fixedly installed on the bottom surface of the connecting ring, a sliding rod is slidably installed inside the connecting rod, a spring is provided in the connecting rod, one end of the spring is connected to the inner wall of the connecting rod, the other end is connected to the top surface of the sliding rod, and the bottom surface of the sliding rod is connected to the top surface of the cone.

[0013] Preferably, a stirring roller is rotatably connected to the center of the mixing device body, and a protective shell is fixedly installed at the center of the bottom surface of the sealing cover. A servo motor is fixedly installed in the protective shell, and the output shaft of the servo motor is connected to the top surface of the stirring roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, a spraying mechanism located below the powder feed pipe outlet causes the falling powder to first impact a cone and vibrate to prevent accumulation. It then falls into a rotating conical dispersion disc, where, under centrifugal force, it is evenly dispersed into a powder curtain through multiple perforations on its surface. This achieves two-stage mechanical dispersion of the powder before it contacts the liquid, allowing it to fall uniformly onto the liquid surface over a large area with low density. This fundamentally avoids the problems of uneven wetting and fish-eye agglomeration caused by concentrated feeding, significantly improving the uniformity and efficiency of mixing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "top", "bottom", "side", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In one typical implementation of this application, please refer to Figures 1-6As shown, a proportioning device for acetamiprid raw materials includes: a support 1 and a mixing equipment body 2. The mixing equipment body 2 has an opening at the top, and a sealing cover 3 is detachably fixed to its top surface by means of flanges and bolts to achieve the sealing of the tank. A liquid feed pipe 4 and a powder feed pipe 5 are welded and fixed to both sides of the top surface of the sealing cover 3, respectively. The two are used to connect to an external liquid metering and conveying system and a powder metering and feeding system. A controller 6 is fixed to the side wall of the support 1 by screws. The controller 6 is preferably a PLC programmable logic controller, which is used to coordinate and control the operation of the entire device.

[0026] A stirring roller 7 is rotatably connected to the center of the mixing equipment body 2 via a bearing for main mixing of the materials in the tank. A protective shell 8 is fixedly installed at the center of the bottom surface of the sealing cover 3 via bolts. A servo motor 9 is fixedly installed in the protective shell 8 via a motor mount. The output shaft of the servo motor 9 is connected to the top surface of the stirring roller 7 via a coupling. Therefore, when the controller 6 starts the servo motor 9, the servo motor 9 drives the stirring roller 7 to rotate and mix the raw materials inside the mixing equipment body 2.

[0027] When preparing the acetamiprid raw material, a certain amount of liquid solvent is first injected into the mixing equipment body 2 through the liquid feed pipe 4. Then, the controller 6 starts the servo motor 9 to drive the stirring roller 7 to stir the liquid at a low speed. Then, the powder raw material (acetamiprid technical, etc.) is added through the powder feed pipe 5.

[0028] The bottom surface of the sealing cap 3 is equipped with a spraying mechanism, which is specifically designed to solve the problem of crusting and fish-eye clumps caused by uneven wetting of powder raw materials (such as acetamiprid technical) when they come into contact with liquid solvents.

[0029] The spraying mechanism includes a connecting column 10, which is fixedly installed on the bottom surface of the sealing cover 3 by welding or bolting, and its position is precisely located directly below the outlet of the powder feed pipe 5. The top surface of the connecting column 10 has a feed port 11, the diameter of which is the same as the diameter of the outlet end of the powder feed pipe 5, to ensure that the powder can fall in smoothly and in a concentrated manner.

[0030] The spraying mechanism also includes a connecting ring 12, which is fixedly installed on the inner wall of the connecting column 10 by welding. Below the connecting ring 12, a cone 13 is installed by multiple sets of vibrating elements evenly distributed along its circumference. The diameter of the cone 13 is smaller than the diameter of the connecting ring 12, thus forming an annular material drop channel around its periphery. The vibrating elements specifically include: a connecting rod 20, which is welded and fixed to the bottom surface of the connecting ring 12; a sliding rod 21, which is slidably inserted into the connecting rod 20; and a spring 22, which is located inside the connecting rod 20. One end of the spring 22 is connected to the inner top wall of the connecting rod 20, and the other end is connected to the top surface of the sliding rod 21. The bottom surface of the sliding rod 21 is fixedly connected to the top surface of the cone 13. This set of elastic suspension system allows the cone 13 to generate buffered vibration in the vertical direction.

[0031] Directly below the cone 13, a conical dispersion disc 14 is provided. A circular groove 15 is opened at the center of the top surface of the conical dispersion disc 14, and multiple through holes 16 are evenly opened on its conical surface. The spraying mechanism also includes a drive assembly for driving the conical dispersion disc 14 to rotate. The drive assembly includes: a fixed column 17, which is vertically fixed to the bottom surface of the circular groove 15 by welding or integral molding; a second protective shell 18, which is fixed to the bottom surface of the cone 13 by bolts; and a drive motor 19, which is fixed to the inside of the second protective shell 18 by a motor mount. The output shaft of the drive motor 19 is connected to the top surface of the fixed column 17 through a coupling. Therefore, when the drive motor 19 is started, the fixed column 17 rotates synchronously, thereby driving the conical dispersion disc 14 fixedly connected to it to rotate synchronously.

[0032] The powder falls into the connecting column 10 through the feed inlet 11 and first falls onto the top surface of the cone 13. The impact force generated by the falling powder acts on the cone 13, causing the sliding rod 21 to compress the spring 22 within the connecting rod 20 and slide, thereby causing a slight vibration of the cone 13. This vibration effectively prevents the powder from accumulating and bridging on the surface of the cone 13, ensuring that all the powder can smoothly slide down the cone surface of the cone 13 to its bottom edge, and through the annular channel between it and the inner wall of the connecting column 10, finally all of it flows into the circular groove 15 on the top surface of the lower conical dispersion disk 14.

[0033] At the same time, the controller 6 starts the drive motor 19, which drives the fixed column 17 and the conical dispersion disk 14 to rotate at high speed. The powder accumulated in the circular groove 15 is quickly thrown from the circular groove 15 to the conical surface of the conical dispersion disk 14 under the action of centrifugal force, and is evenly sprayed out in a mist through all the holes 16.

[0034] Since the conical dispersing disc 14 rotates above the liquid surface of the mixing equipment body 2, the powder thrown out from the drain hole 16 forms a large area of ​​powder curtain, which falls evenly and dispersedly onto the liquid surface below, which is stirred by the stirring roller 7. This increases the initial contact area between the powder and the liquid, avoiding the problem of instantaneous crusting and internal dry powder agglomeration caused by a large amount of powder falling into a certain point of the liquid. Thus, it effectively inhibits the formation of fish-eye-shaped difficult-to-disperse clumps from the root and solves the problem of uneven wetting. Finally, all raw materials are uniformly mixed in the mixing equipment body 2 under the continuous action of the stirring roller 7.

[0035] Working principle:

[0036] In operation, liquid is injected into the mixing equipment body 2 through the liquid feed pipe 4 and agitated by the stirring roller 7. Powdered raw materials fall into the connecting column 10 through the powder feed pipe 5, first impacting the cone 13, whose vibrating components prevent accumulation, allowing the powder to flow into the circular groove 15 of the conical dispersion disk 14. Simultaneously, the drive motor 19 starts, driving the conical dispersion disk 14 to rotate at high speed. Under the action of centrifugal force, the powder is evenly scattered through its perforations 16, forming a dispersed powder curtain. This design allows the powder to be mechanically dispersed first, and then to contact the liquid surface below with a large area and low density, fundamentally avoiding the formation of concentrated agglomerates and fish-eye clumps, solving the problem of uneven wetting, and finally, the stirring roller 7 completes the final uniform mixing.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
