Description

Technical Field

[0001] This utility model relates to the technical field of lime-sulfur mixture production equipment, specifically a reaction vessel for lime-sulfur mixture production. Background Technology

[0002] Lime sulfur is a commonly used pesticide, primarily used to control pests and diseases. Its main raw materials include quicklime, sulfur powder, and water, with a mass ratio of 1:2:10–13 during the reaction. In the production process of lime sulfur, the reaction vessel is the core equipment, and its performance directly affects the product quality and production efficiency.

[0003] Existing technologies for lime-sulfur mixture production reactors, such as the one disclosed in patent CN 220328654 U, while improving production efficiency to some extent, still have some problems. This patent's reactor primarily uses a feeding device to deliver raw materials into the reactor body, where they are initially crushed by a crushing component, then stirred by a stirring blade, and finally cooled by a cooling component. However, this design has the following shortcomings:

[0004] Temperature control is not precise enough. Although the cooling system of the reactor can cool the solution inside, its cooling effect mainly relies on the circulation of the coolant and the cooling effect of the semiconductor refrigeration unit. While this cooling method can quickly lower the solution temperature, the temperature fluctuations inside the reactor during production are quite drastic, making precise control of the reaction temperature difficult. Especially in the early stages of the reaction, the dissolution and stirring of the raw materials generate a large amount of heat, causing the internal temperature of the reactor to rise rapidly. The cooling system's cooling rate is relatively slow, making it impossible to control the temperature within a suitable range in a timely manner, thus affecting the stability of the reaction and product quality.

[0018] (III) Beneficial Effects

[0019] This utility model provides a reaction vessel for producing lime-sulfur mixture, which has the following beneficial effects:

[0020] 1. This reaction vessel for producing lime-sulfur mixture achieves precise temperature control by installing a first spiral coil and a second spiral coil within the jacketed cavity of the vessel body to transport steam and room-temperature water, respectively. In the initial stage of the reaction, controlling the steam flow rate and temperature allows for rapid heating of the vessel to a suitable reaction temperature. During the reaction, adjusting the room-temperature water flow rate effectively controls internal temperature fluctuations, preventing adverse effects from excessively high or low temperatures. Furthermore, temperature and pressure sensors monitor the internal temperature and pressure data in real time and transmit the data to a control board. The control board automatically adjusts the steam and room-temperature water flow rates according to a preset program, further improving the accuracy and stability of temperature control. This precise temperature control not only ensures stable reaction but also improves the quality and yield of the lime-sulfur mixture, effectively solving the problem of insufficient temperature control in existing reaction vessels.

[0021] 2. The reaction vessel of this invention improves the mixing uniformity of raw materials through optimized design of the stirring assembly. The stirring assembly includes a servo motor, a rotating shaft, and multiple stirring rods. The output shaft of the servo motor is connected to the rotating shaft, which drives the stirring rods to rotate, thereby achieving thorough mixing of the raw materials inside the inner shell. Furthermore, by setting multiple feed pipes to transport quicklime powder, sulfur powder, and water respectively, the raw materials can be more evenly distributed when entering the vessel. During the stirring process, the rotation of the stirring rods further promotes the mixing of the raw materials, ensuring sufficient reaction of each component and avoiding incomplete reaction and unstable product quality caused by uneven distribution of raw materials. This uniform mixing method not only improves the quality of the lime-sulfur mixture but also reduces the generation of impurities during the production process, improving the purity and stability of the product.

[0057] In use, the reaction vessel for producing lime-sulfur mixture of this invention first supplies quicklime powder, sulfur powder, and water to the inner shell 102 of the vessel body 1 via the feeding component. The specific process is as follows:

[0058] 1. Raw material conveying: Quicklime powder is conveyed to the first feed pipe 20 through the first raw material tank 17, the first screw pump 18 and the first feed pipe 19, and then enters the inner shell 102 through the first feed pipe 20.

[0059] Sulfur powder is transported to the second feed pipe 24 through the second raw material tank 21, the second screw pump 22, and the second feed pipe 23, and then enters the inner shell 102 through the second feed pipe 24.

[0060] Water is transported to the third feed pipe 10 through the water tank 3, the second water pump 8, and the second water supply pipe 9, and then enters the inner shell 102 through the third feed pipe 10.

[0061] II. Temperature control: The steam generated by the steam generator 6 is transported to the first spiral coil 106 through the steam pipe 7 to heat the inner shell 102, so that the raw materials reach a suitable reaction temperature.

[0062] The clean water in the water tank 3 is pumped to the second spiral coil 107 by the third water pump 11 to cool the inner shell 102 and prevent the temperature from being too high and causing adverse effects on the reaction.

[0063] Temperature sensor 26 and pressure sensor 27 monitor the temperature and pressure data inside the inner shell 102 in real time and transmit the data to the control board. The control board automatically adjusts the flow rates of steam and room temperature water according to a preset program to ensure that the temperature inside the vessel 1 remains stable within a suitable range.

[0064] III. Stirring and Mixing: The servo motor 103 starts, and its output shaft drives the rotating shaft 104 to rotate, which in turn drives the stirring rod 105 to rotate, thereby achieving thorough stirring of the raw materials inside the inner shell 102. The rotation of the stirring rod 105 can promote the mixing between the raw materials, allowing each component to react fully and avoiding problems such as insufficient reaction and unstable product quality caused by uneven distribution of raw materials.

[0065] IV. Discharge: After the reaction is completed, the reacted material, namely lime-sulfur mixture, is discharged through the discharge pipe 14. A first control valve 15 is installed on the discharge pipe 14 to control the opening and closing of the internal flow channel of the discharge pipe 14.
