[0002] The dissolution of pyrazole compounds must be closely considered in conjunction with their specific structure and physicochemical properties. Due to differences in substituents (such as the presence of nitro, chlorine, trifluoromethyl, etc.), their polarity, stability and solubility vary significantly, requiring the selection of dissolution devices and methods accordingly.

This utility model provides a chemical dissolving device that can fully dissolve materials. Its structure includes a vessel body and a vessel lid, which are sealed together by a flange. A sieve cylinder is installed inside the vessel body, and sieve holes are evenly distributed on the bottom surface and walls of the sieve cylinder. A frequency converter is connected to the motor. This chemical dissolving device has a simple structure, is easy to use, and can fully dissolve materials.
[0004] Chinese patent CN221752902U discloses a chemical production dissolving device, including a base plate, a base fixedly connected to one side of the top of the base plate, and a dissolving tank on one side of the base. This utility model can continuously vibrate the screen by setting an oscillating motor, which facilitates the screening of crushed chemical raw materials.

Furthermore, wet raw materials are prone to clumping and clogging the pipeline, affecting the continuity of processing. In the transportation of liquid raw materials, high-viscosity raw materials often stagnate and clog due to their poor fluidity, requiring additional manual intervention and making it difficult to smoothly enter the reaction system.
[0007] To solve the above problems, this utility model provides a pyrazole ring dissolving device, including a chemical dissolving component, a solid feeding component at the left end of the chemical dissolving component, a liquid feeding component at the front end of the chemical dissolving component, a heat source reuse component at the upper end of the chemical dissolving component, and a paste feeding component at the rear end of the chemical dissolving component.

[0008] In the above-mentioned pyrazole ring dissolution device, the chemical dissolution component, solid feeding component, liquid feeding component, and heat source reuse component work together to achieve efficient dissolution of pyrazole ring raw materials in different states.

[0016] In summary, within the chemical dissolution components of this solution, the main dissolution chamber provides a stable reaction space, ensuring orderly dissolution. The dissolution injection pipe, in conjunction with the dissolution storage tank, achieves stable solvent delivery, ensuring sufficient supply. Multiple valves precisely control the connectivity of each raw material channel, adjusting the feeding timing and rate to avoid mixing and improve reaction controllability.

A sieve screens qualified particles to prevent large pieces of raw material from causing incomplete dissolution. The conveying pipeline ensures smooth transport, and a heating layer preheats the raw materials to prevent moisture-induced clumping and reduce... To reduce the risk of blockages and improve the continuity and stability of processing, the liquid feeding assembly provides a dedicated channel for liquid raw materials through the liquid injection pipeline.

[0019] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0020] First implementation method: Figures 1-5 A pyrazole ring dissolving device is shown, including a chemical dissolving component 1, a solid feeding component 2 at the left end of the chemical dissolving component 1, a liquid feeding component 3 at the front end of the chemical dissolving component 1, a heat source reuse component 4 at the upper end of the chemical dissolving component 1, and a paste feeding component 5 at the rear end of the chemical dissolving component 1. The chemical dissolving assembly 1 includes a dissolving main chamber 100, a dissolving liquid injection pipe 101 connected to the dissolving main chamber 100, a dissolving liquid storage tank 102 connected to the dissolving liquid injection pipe 101, and a plurality of valve ports 103 provided on the inner wall of the dissolving main chamber 100. Solid feeding assembly 2, located at the left end of chemical dissolving assembly 1, includes a conveying pipe 204, a solid crushing chamber 200 located at the upper end of the conveying pipe 204, a chamber door 201 hinged to the upper end of the solid crushing chamber 200, an external motor shearing and crushing shaft 202 installed inside the solid crushing chamber 200, a screen 203 fixed at the lower end of the solid crushing chamber 200, and a heating partition 205 covering the outer wall of the solid crushing chamber 200, wherein the screen 203 is located between the external motor shearing and crushing shaft 202 and the conveying pipe 204; The liquid feeding assembly 3 is located at the front end of the chemical dissolving assembly 1 and includes a liquid injection pipe 300 connected to the dissolving main chamber 100, a pump 301 installed in the middle of the liquid injection pipe 300, and a heating sleeve 302 covering the outside of the liquid injection pipe 300 and the pump 301.
[0021] It also includes a heat source reuse component 4, which includes a steam conveying pipe 400. The steam conveying pipe 400 is fixedly connected to the upper end of the dissolving main chamber 100. The outer wall of the steam conveying pipe 400 is covered with an insulation sleeve 404. The rear end of the steam conveying pipe 400 is fixedly connected to a plate heat exchanger 402. A nitrogen injection tank 401 is installed at the rear end of the plate heat exchanger 402. The lower end of the plate heat exchanger 402 is fixedly connected to multiple heat source reuse pipes 403. The multiple heat source reuse pipes 403 are interconnected with the heating partition 205 and the heating sleeve 302, respectively.
[0022] Figures 1-5 The diagram shows that the pyrazole ring dissolution device achieves efficient dissolution of pyrazole ring raw materials in different states through the coordinated operation of the chemical dissolution component 1, solid feed component 2, liquid feed component 3, and heat source reuse component 4. The chemical dissolution component 1 serves as the core reaction unit, and its main dissolution chamber 100 provides reaction space for the dissolution of pyrazole rings. The dissolution liquid injection pipe 101 transports the solvent in the dissolution liquid storage tank 102 to the main dissolution chamber 100. Multiple valve ports 103 control the connection status between the dissolution liquid injection pipe 101, the liquid injection pipe 300, the conveying pipe 204, and the paste injection pipe 500 and the main dissolution chamber 100, ensuring that each raw material enters the reaction system in sequence.
[0023] Solid feed assembly 2 is responsible for processing solid pyrazole ring raw materials. Open the door 201 at the top of the solid crushing chamber 200 and put the solid raw materials into the chamber. The external motor shearing shaft 202 rotates at high speed to crush the raw materials. The crushed particles are screened by screen 203. Particles that meet the particle size requirements pass through the screen and are transported to the dissolving main chamber 100 by the conveying pipe 204. The heating partition 205 at the outer end of the solid crushing chamber 200 can preheat the raw materials in the chamber to prevent the damp raw materials from clumping and clogging the screen or pipe.
[0024] The liquid feed assembly 3 is used to transport liquid pyrazole ring raw materials. The liquid injection pipe 300 introduces the liquid raw materials into the dissolution main chamber 100. The pump 301 in the middle provides the conveying power. The heating sleeve 302 on the outside of the liquid injection pipe 300 and the pump 301 can heat and keep warm, reduce the flow resistance of the high viscosity liquid raw materials, and ensure smooth conveying.
[0025] The heat source reuse component 4 realizes the recycling of energy. The steam generated during the reaction in the main dissolution chamber 100 is transported to the plate heat exchanger 402 via the steam conveying pipe 400. The insulation sleeve 404 outside the steam conveying pipe 400 reduces heat loss. The nitrogen injection tank 401 injects nitrogen into the plate heat exchanger 402. After the nitrogen and steam complete heat exchange in the heat exchanger, they are transported to the heating partition 205 of the solid feed component 2 and the heating sleeve 302 of the liquid feed component 3 via multiple heat source utilization pipes 403, respectively, to provide heat source for the solid crushing chamber and the liquid pipeline, realizing waste heat recovery. The raw materials transported by each component are fully mixed with the solvent in the main dissolution chamber 100. The feed rate is adjusted by the precise control of the valve port 103, and finally the efficient dissolution reaction of the pyrazole ring is completed.
[0026] Second implementation method: Figure 6-7 A pyrazole ring dissolving device is shown, which also includes a paste feeding assembly 5. The paste feeding assembly 5 includes a paste injection pipe 500 connected to the rear end of the dissolving main chamber 100. A spiral conveying shaft 501 is installed at the inner end of the paste injection pipe 500. Multiple valve ports 103 are interconnected with the dissolving liquid injection pipe 101, the liquid injection pipe 300, the conveying pipe 204, and the paste injection pipe 500, respectively. A 57 series stepper motor connected to the spiral conveying shaft 501 continuously feeds the paste raw material into the dissolving main chamber 100 using the propulsive force of the spiral blades. Due to the diverse properties of pyrazole ring compounds, in some synthesis processes or formulations, pyrazole ring raw materials may exist in paste form with high viscosity. Ordinary conveying methods are difficult to ensure smooth material transport and are prone to accumulation and blockage of pipelines. Therefore, the paste feeding component 5 is designed for paste-like pyrazole ring raw materials. The spiral conveying shaft 501 inside the paste injection pipeline 500 rotates and propels the paste raw material continuously into the dissolving main chamber 100, avoiding the accumulation and blockage of pipelines due to excessive viscosity. The paste feeding component 5 can be used as an optional accessory for paste materials.
[0027] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
