Description

Technical Field

[0001] This utility model relates to the field of agricultural fungicide preparation technology, specifically to a lime sulfur mixture preparation equipment. Background Technology

[0002] Lime sulfur, a broad-spectrum agricultural fungicide, has long been widely used in orchards and farmland due to its readily available raw materials, low cost, and significant control effects against various plant diseases. Traditional lime sulfur preparation relies on manual operation, involving the heating and reaction of quicklime, sulfur, and water to generate a calcium polysulfide solution. However, manual preparation suffers from inaccurate temperature control, uneven mixing of raw materials, and localized overheating and charring, easily leading to loss of active ingredients or incomplete reactions, affecting the stability of the agent's quality. Furthermore, the oxidation reaction between sulfur and lime during preparation requires full contact and uniform heating; the static stirring and single heating modes of traditional equipment cannot meet the demands for efficient mass and heat transfer, resulting in long reaction times and high energy consumption.

[0003] With the development of large-scale agricultural production, although existing industrial-scale boiling equipment has introduced mechanical stirring mechanisms to improve mixing effects, it still faces many technical bottlenecks: First, the material often adheres to the stirring components on the side walls and bottom of the tank, and the residual material is prone to carbonization due to localized high temperatures, which not only reduces thermal efficiency but also contaminates subsequent batches of product; Second, conventional aeration methods mostly rely on external pipelines or fixed nozzles, resulting in uneven gas distribution and difficulty in penetrating high-viscosity material layers, especially forming stirring blind zones at the bottom of the tank; Third, the scraping structure has a single function, and the linkage between the side wall scrapers and the bottom scrapers is insufficient, resulting in limited dynamic cleaning effects. These problems restrict the large-scale and continuous production of lime-sulfur mixture, and there is an urgent need to achieve efficient mixing, precise temperature control, and energy consumption optimization through equipment structural innovation. Utility Model Content

[0004] The main purpose of this utility model is to provide a lime-sulfur mixture preparation device that has good stirring and mixing effects and can prevent lime-sulfur mixture from adhering to the inner wall of the tank.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A lime-sulfur mixture preparation device includes a tank, a discharge pipe at the bottom of the tank, a heating mechanism at the bottom of the tank, and a water inlet pipe, an exhaust pipe, a lime inlet pipe, and a sulfur inlet pipe fixedly connected to the top of the tank. A stirring assembly is concentrically rotated inside the tank, and a drive unit for driving the stirring assembly is located at the top of the tank. The stirring assembly is hollow inside, and a rotary joint is rotatably and sealed at the top of the stirring assembly. The rotary joint is connected to the exhaust pipe, and an air pump is installed on the exhaust pipe. Multiple first air valves are provided on the stirring assembly. Second scrapers are fixed on both the left and right sides of the stirring assembly inside the tank, and the second scrapers slide in contact with the side wall of the tank. A bottom scraping unit is provided at the bottom of the stirring assembly.

[0006] Specifically, the stirring assembly includes a rotating tube rotatably connected to the tank body, the rotating tube passing through the top plate of the tank body, a rotating joint being rotatably and sealingly connected to the upper end of the rotating tube, multiple stirring tubes being fixedly connected to both sides of the rotating tube inside the tank body, multiple first air valves being provided on the stirring tubes, and a second scraper being fixedly connected to the stirring tubes.

[0007] Specifically, the drive unit includes a motor fixed to the upper end of the tank, a first gear concentrically fixed on the output shaft of the motor, and a second gear concentrically fixed on the rotating tube, with the first gear meshing with the second gear.

[0008] Specifically, the rotary joint is connected to the exhaust pipe through a branch pipe, which is a rigid pipe. One end of the branch pipe is fixedly connected to the exhaust pipe, and the other end of the branch pipe is fixedly connected to the rotary joint.

[0009] Specifically, the bottom scraping unit includes a first scraper, which is fixedly connected to the lower end of the second scraper and the lower end of the rotating tube, and the lower end of the first scraper slides in contact with the upper end of the tank bottom plate.

[0010] Specifically, the bottom scraping unit includes a third scraper, which is inclined and fixedly connected to the lower end of the rotating tube. The third scraper is hollow inside and communicates with the rotating tube. The downward-inclined end of the third scraper slides in contact with the upper end of the bottom plate of the tank. Multiple second air valves are installed on the upward-inclined end of the third scraper, and the second air valves communicate with the interior of the third scraper.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. During rotation, the hollow stirring assembly releases gas simultaneously through the first and second jet valves. The gas flow and mechanical stirring work synergistically, enabling the material to achieve three-dimensional mixing in both horizontal and vertical directions, significantly shortening the mixing time. In Example 2, the inclined design of the third scraper pushes the bottom material upwards during rotation, effectively breaking up the sediment layer of high-viscosity materials and preventing component decomposition or coking caused by excessively high local temperatures at the bottom.

[0012] 2. The first and second scrapers rotate synchronously with the stirring assembly, scraping away material adhering to the bottom and side walls of the tank in real time. This prevents residues from carbonizing due to prolonged heating and contaminating new batches of material. Simultaneously, it ensures the heating surface directly contacts fresh material, improving heat transfer efficiency. The synchronous movement of the scrapers and stirring assembly requires no additional power source, resulting in a simple and highly reliable structure suitable for continuous production scenarios, reducing downtime for cleaning.

[0013] 3. Gas is directly introduced into the hollow mixing assembly through the exhaust pipe, branch pipe, and rotary joint, eliminating the need for external aeration pipelines. This avoids the risks of external pipe entanglement or wear, simplifies equipment layout, and reduces maintenance costs. The first and second jet valves release gas in separate zones, providing differentiated aeration for the upper, middle, and bottom of the tank, enhancing the overall flowability of the material and avoiding gas loss and waste associated with traditional single aeration modes.

[0014] 4. The synergistic effect of dynamic scraping and aeration ensures uniform heating of the material, preventing excessive decomposition of calcium polysulfides due to localized overheating and maintaining the stability of effective components. Standardized operation of mechanical aeration and stirring reduces reliance on manual experience and solves the problem of batch-to-batch fluctuations in effective components caused by uneven stirring in traditional processes.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figures 1-3 As shown, a lime-sulfur mixture preparation device includes a tank 1, and a discharge pipe 2 is provided at the bottom of the tank 1.

[0022] A heating mechanism 3 is installed at the lower end of the tank body 1.

[0023] The upper end of the tank 1 is fixedly connected to a water inlet pipe 6, an exhaust pipe 7, a lime inlet pipe 8, and a sulfur inlet pipe 9.

[0024] A stirring assembly is concentrically rotated inside the tank body 1. A drive unit is provided at the upper end of the tank body 1 to drive the stirring assembly to rotate. The stirring assembly is hollow inside. A rotating joint 11 is rotatably and sealed at the upper end of the stirring assembly. The rotating joint 11 is connected to the exhaust pipe 7 through a branch pipe 10. The branch pipe 10 is a rigid pipe. One end of the branch pipe 10 is fixedly connected to the exhaust pipe 7, and the other end of the branch pipe 10 is fixedly connected to the rotating joint 11.

[0025] An air pump 20 is installed on the exhaust pipe 7, and multiple first air valves 17 are opened on the stirring assembly. Second scrapers 15 are fixed on both the left and right sides of the stirring assembly inside the tank 1, and the second scrapers 15 slide in contact with the side wall of the tank 1.

[0026] The stirring assembly includes a rotating tube 12 rotatably connected to the tank body 1. The rotating tube 12 passes through the top plate of the tank body 1. The rotating joint 11 is rotatably and sealed to the upper end of the rotating tube 12. Multiple stirring tubes 13 are fixedly connected to both sides of the rotating tube 12 inside the tank body 1. Multiple first air valves 17 are provided on the stirring tubes 13. The second scraper 15 is fixedly connected to the stirring tubes 13.

[0027] The drive unit includes a motor 4 fixed to the upper end of the tank body 1. A first gear 5 is concentrically fixed on the output shaft of the motor 4, and a second gear 16 is concentrically fixed on the rotating tube 12. The first gear 5 and the second gear 16 mesh.

[0028] A bottom scraping unit is provided at the lower end of the stirring assembly. The bottom scraping unit includes a first scraper 14, which is fixedly connected to the lower end of the second scraper 15 and the lower end of the rotating tube 12. The lower end of the first scraper 14 slides in contact with the upper end of the bottom plate of the tank body 1.

[0029] Water, lime, and sulfur are added to tank 1 through water inlet pipe 6, lime inlet pipe 8, and sulfur inlet pipe 9, respectively. Then, the valve of exhaust pipe 7 is closed and heating mechanism 3 is started to heat the mixture in tank 1.

[0030] Start motor 4. Motor 4 drives rotating tube 12, stirring tube 13, first scraper 14 and second scraper 15 to rotate through first gear 5 and second gear 16. Stirring tube 13 can stir the material in tank 1. First scraper 14 and second scraper 15 can scrape off the material adhering to the bottom wall and side wall of tank 1 to prevent the material adhering to the bottom wall and side wall of tank 1 from being overheated and calcified.

[0031] During the heating and stirring process of the material in tank 1, air pump 20 is started. Air pump 20 causes the gas in tank 1 to be discharged through exhaust pipe 7, branch pipe 10, rotary joint 11, rotary pipe 12, stirring pipe 13 and first jet valve 17. The gas discharged from the first jet valve 17 can cause the material in tank 1 to churn, thereby aerating the material in tank 1, improving the mixing rate and effect of the material in tank 1, and reducing the stirring time, thus saving energy. After the material is stirred, it is discharged from discharge pipe 2.

[0032] Example 2: Based on Example 1, referring to... Figure 4 As shown, the bottom scraping unit includes a third scraper 18, which is inclined and fixedly connected to the lower end of the rotating tube 12. The interior of the third scraper 18 is hollow and communicates with the rotating tube 12. The downward inclined end of the third scraper 18 slides in contact with the upper end of the bottom plate of the tank 1. A plurality of second air valves 19 are installed on the upward inclined end of the third scraper 18, and the second air valves 19 communicate with the interior of the third scraper 18.

[0033] When the rotating tube 12 rotates, the third scraper 18 rotates accordingly. Because the third scraper 18 is set at an inclination, when the third scraper 18 rotates, the material in the lower part of the tank 1 can be turned upwards, ensuring that the material in the tank 1 is heated evenly.

[0034] After the air pump 20 is started, some gas is discharged from the second air valve 19. The gas discharged from the second exhaust valve can aerate the material in the lower part of the tank 1, which can further improve the mixing rate of the material.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
