Description

Technical Field

[0001] The utility model belongs to the field of chemical industry, and in particular relates to a multi-channel dilution kettle for chemical plants. Background Art

[0002] In the chemical industry, dilution kettles are commonly used in the chemical industry, mainly for mixing and diluting concentrated chemicals or solutions with solvents. This equipment is widely used in laboratories, chemical production and the pharmaceutical industry. By accurately controlling the ratio of solutes and solvents in the dilution kettle, the concentration of the solution can be accurately adjusted to meet the specific needs of the experiment or production process. In the pharmaceutical industry, dilution kettles are usually used to prepare the solution concentration required in drug formulations to ensure the accurate preparation of drug preparations. At the same time, in chemical laboratories, dilution kettles can also be used to dilute and mix chemical reagents for subsequent experimental operations. In general, dilution kettles are a common equipment in the chemical industry, used to accurately control solution concentrations and prepare solutions, and are widely used in chemical, pharmaceutical and laboratory fields.

[0003] The existing high-efficiency dilution kettle (for example, application number: CN218501808U) generally has the following problems during use:

[0004] 1. The feed channel is a single channel. When adding raw materials, the latter raw material will react with the remnants of the former raw material in the channel: Uneven reaction: Due to the uneven mixing of the remnants of the former raw material and the latter raw material in the channel, uneven reaction may occur, affecting the quality and output of the product. Difficulty in controlling the reaction rate: Due to the reaction of the latter raw material with the remnants of the former raw material in the channel, a violent reaction may occur, making the reaction rate difficult to control and even causing safety problems. Raw material waste: If the remnants of the former raw material do not match the latter raw material or the proportion is inappropriate, it may lead to raw material waste and increase production costs. Low equipment utilization: Due to the existence of reactions in the channel, the equipment may be in a non-optimal working state part of the time, reducing equipment utilization, so a multi-channel dilution kettle is urgently needed.

[0005] 2. The internal reaction is too intense, causing the internal pressure to exceed the threshold, and it is impossible to know it in the first time: Increased safety risks: If the pressure cannot be controlled in time, it may cause equipment damage or even safety accidents such as explosions. Production interruption: In order to ensure safety, it is necessary to stop operations and inspect and adjust the equipment, which will cause interruptions to the production line. Reduced equipment life: Excessive pressure will cause greater wear and tear on the equipment, thereby shortening the service life of the equipment. Environmental pollution risk: If the pressure is too high and the equipment is damaged, it may cause the leakage of chemicals and pollute the environment. Economic losses: Excessive pressure may not only cause equipment damage, but also trigger a series of chain reactions, such as delays in production plans, compensation, etc., causing economic losses and reducing the operating temperature of the water pump. Therefore, a dilution kettle that can remotely alarm is urgently needed.

[0006] 3. Insufficient diluent reaction: Product quality declines: If the diluent cannot fully react with the main raw material, the performance, purity or stability of the final product may be affected, thereby affecting the quality and market competitiveness of the product. Waste of resources: If the diluent does not react fully, part of the diluent may not be effectively utilized, resulting in a waste of raw material costs. Reduced production efficiency: In order to ensure product quality, it may be necessary to increase the reaction time or take other remedial measures, thereby extending the production cycle and reducing production efficiency. Increased equipment wear: If the reaction is not sufficient, certain chemicals may form deposits in the equipment, which will not only affect the normal operation of the equipment, but may also cause equipment corrosion and wear. Safety hazards: Certain unreacted substances may accumulate in the equipment, which may cause safety problems such as explosions, leaks, etc. under certain conditions (such as temperature changes or pressure fluctuations). Environmental pollution: If the inadequate reaction leads to the emission of harmful substances, it may cause pollution to the environment, so there is an urgent need for a dilution kettle that can make the internal raw materials react more fully.

This is very valuable for accident investigation, cause analysis and improvement of production processes.

[0015] 3. By setting the diluent stirring shaft and double-layer diluent stirring blades inside, the diluted liquid is fully stirred, and the following advantages are brought: Improve mixing uniformity: The double-layer stirring blade design can provide a larger stirring area and stronger stirring force, ensuring that the diluted liquid is fully and evenly mixed in the dilution kettle. This helps to improve the quality and stability of the product. Shorten the mixing time: The strong stirring force can accelerate the mixing process of the diluted liquid, thereby shortening the mixing time. This helps to improve production efficiency, reduce energy consumption and reduce production costs. Reduce dead corners and residues: The double-layer stirring blades can more comprehensively cover various areas in the dilution kettle, reduce dead corners and residues, and ensure that all diluted liquids can be evenly mixed. Enhance the reaction effect: By fully stirring the diluted liquid, the mixing and contact between the reactants can be promoted, thereby improving the reaction effect and the quality of the product. Reduce temperature fluctuations: During the stirring process, the diluted liquid can better dissipate heat, reduce the impact of temperature fluctuations on the production process, and help maintain temperature stability. Promote chemical reaction balance: By fully stirring, the chemical reaction can be promoted to a balanced state, thereby improving the purity and yield of the product.

A network-connected alarm device 2 is arranged on the side of the dilution kettle shell 1, which can promptly provide feedback upward when the internal pressure exceeds the threshold value, thereby reducing the time for discovering the accident by 20% and avoiding further expansion of the accident.

[0027] The multi-channel dilution kettle for chemical plants: a liquid discharge valve 5 is arranged at the top of the liquid discharge port 4, which can effectively limit the leakage of internal liquid and prevent the dilution outflow from causing waste and pollution to the surrounding environment.

[0028] The multi-channel dilution kettle for chemical plants: the dilution kettle reaction catalyst adding modules 12 are arranged at the upper and lower ends of the dilution kettle shell 1.
