Description

Technical Field

[0001] This utility model relates to a snow melting agent production device, specifically a high-efficiency and environmentally friendly snow melting agent preparation device, belonging to the field of snow melting agent production technology. Background Technology

[0002] Snow melting agents are a class of functional chemical or mixed materials used to quickly melt snow and ice on outdoor facilities such as roads, bridges, and airports. Their core function is to lower the freezing point of snow and ice and break the adhesion between snow and ice and the ground, thereby achieving the goal of snow and ice removal and ensuring traffic safety.

[0003] An existing patent (publication number: CN222076119U) discloses a device for preparing a slow-release de-icing agent. This invention produces a slow-release de-icing agent through a closed-loop process, effectively preventing air pollution and meeting environmental protection requirements. Furthermore, its high degree of automation ensures efficient production and precise control of process parameters, ultimately guaranteeing the slow-release performance of the de-icing agent. While the closed-loop production process achieves high efficiency and environmental friendliness, the raw materials for de-icing agents are mostly in solid particulate form. If the mixing of raw materials relies solely on heat convection during the heating process, particle agglomeration is highly likely. This directly results in uneven coating of the raw material particles: some particles have excessively thick coatings, while others are not effectively coated, ultimately severely weakening the consistency of the slow-release performance of the finished de-icing agent and failing to meet the stable snow removal requirements in practical applications. Utility Model Content

[0004] This invention provides a highly efficient and environmentally friendly de-icing agent preparation device to solve the problems of particle agglomeration and uneven coating.

[0005] The present invention achieves the above objectives through the following technical solution: a high-efficiency and environmentally friendly snow melting agent preparation device, including a feeding channel, a protective shell fixedly installed on one side of the feeding channel, and a conveying pipeline inserted into the top of the protective shell, and a preparation mechanism is provided inside the protective shell; The preparation mechanism includes a preparation vessel, which is embedded inside a protective shell. A screw conveyor is embedded at the bottom of the preparation vessel. A vibrating fluidized bed is fixedly installed at one end of the main body of the screw conveyor, and a flow pipe extends out from one side of the vibrating fluidized bed. A mixing vessel is fixedly installed at the bottom of the protective shell.

[0006] As a further improvement of this utility model: a support rod is embedded at the bottom of the mixing vessel, and an addition tank is provided at the front end of the mixing vessel.

[0007] As a further embodiment of this utility model: the preparation vessel is connected to the vibrating fluidized bed via a spiral conveying device, and the vibrating fluidized bed is connected to the mixing vessel via a flow pipe.

[0008] As a further improvement of this utility model: the mixing vessel is equipped with a filter plate, and a mixing mechanism is provided on one side of the mixing vessel.

[0009] As a further embodiment of this utility model: the mixing mechanism includes a mounting shell, which is embedded in the outer wall of the mixing vessel, and a Helmholtz coil is embedded inside the mounting shell.

[0010] As a further embodiment of this utility model: an ultrasonic generator is embedded in the outer wall of the protective shell corresponding to the interior of the outer shell, and a transducer is embedded below the preparation vessel inside the protective shell.

[0011] As a further improvement of this utility model: the top of the mounting shell is provided with a through hole, and a mounting cylinder is inserted into the inside of the through hole.

[0012] As a further improvement of this utility model: the interior of the mounting cylinder is provided with a flow cavity, and a filter screen is embedded inside the flow cavity, with a cooling fan embedded at the bottom end of the filter screen.

[0013] The beneficial effects of this utility model are: 1. This device introduces modified polystyrene porous microspheres into the pipeline according to a preset ratio. The porous structure can achieve preliminary dispersion and precise positioning of the raw material salt. The polyacrylamide coating on the surface can also act as a bridge for the transmission of corrosion inhibitor, guiding the corrosion inhibitor to uniformly fill the pores of the microspheres and completely coat the surface of the raw material salt. This avoids the problem of raw material salt agglomeration from the source, ensures the uniformity of the coating of the subsequent finished product, achieves deep coating and mixing, improves the dispersibility of raw material salt, strengthens the combination stability of corrosion inhibitor and raw material salt, realizes precise and controllable corrosion inhibition coating, and enhances the product's corrosion resistance and application adaptability. 2. This device pre-mixes activated trace amounts of magnetic nanoparticles into the corrosion inhibitor in the addition tank. The ultrasonic generator and transducer embedded in the protective shell work together to achieve full-field resonance of the material without dead angles. This avoids damage to the particle structure caused by shear force and effectively disperses the initial agglomerates of the raw salt, promoting uniform embedding into the microsphere pores and significantly improving pre-adsorption adhesion. At the same time, the cavitation effect refines the corrosion inhibitor particles and removes residual air bubbles in the pores, promoting full contact between the raw salt and the corrosion inhibitor, and helping the magnetic nanoparticles to uniformly fill the pores and tightly adhere to the salt particle surface. With the magnetic field adjustment function of the Helmholtz coil, the magnetic nanoparticles can be directionally guided, driving the corrosion inhibitor to migrate directionally along the magnetic field direction, achieving uniform adsorption on the surface of the raw salt. By precisely controlling the magnetic field strength, the deposition thickness of the corrosion inhibitor can be accurately controlled, effectively avoiding local aggregation, and ultimately achieving active directional distribution of the corrosion inhibitor. This design not only significantly improves coating uniformity and corrosion inhibitor utilization, reducing raw material waste, but also enhances the bonding strength between the coating layer and salt particles through the reinforcing effect of magnetic nanoparticles, preventing corrosion inhibitor from falling off during use. The synergistic effect of ultrasound and magnetic field also reduces reaction energy consumption and shortens the coating cycle, while making the product's corrosion resistance more stable and adaptable to a wider range of scenarios. It can efficiently meet both long-term protection under complex working conditions and special needs for precise control of corrosion inhibition efficiency. Attached Figure Description

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.

[0017] Example 1 like Figures 1 to 5 As shown, a high-efficiency and environmentally friendly de-icing agent preparation device includes a feeding channel 1, a protective shell 2 fixedly installed on one side of the feeding channel 1, a conveying pipe network 3 inserted into the top of the protective shell 2, and a preparation mechanism 4 arranged inside the protective shell 2; the preparation mechanism 4 includes a preparation vessel 401, which is embedded inside the protective shell 2, and a screw conveyor 402 is embedded at the bottom of the preparation vessel 401. A vibrating fluidized bed 403 is fixedly installed at one end of the main body of the screw conveyor 402, and a flow pipe 404 extends out from one side of the vibrating fluidized bed 403. The bottom of the protective shell 2 is fixedly equipped with a... The mixing vessel 405 is equipped with a preparation vessel 401 inside the protective shell 2, which is first introduced into the raw material salt through the feeding channel 1. Modified polystyrene porous microspheres are introduced into the preparation vessel 401 through the conveying pipeline 3 and mixed in proportion. The porous structure of the microspheres is used to achieve the initial dispersion and positioning of the raw material salt. After being conveyed to the vibrating fluidized bed 403 by the screw conveyor 402 for drying, the raw material salt enters the mixing vessel 405 through the cooperation of the conveying power equipment and the flow pipe 404. At the same time, the corrosion inhibitor is introduced into the addition tank 407 through its matching conveying power equipment and pipeline, and is fully mixed with the raw material.

[0018] Furthermore, a support rod 406 is embedded at the bottom of the mixing vessel 405, and an addition tank 407 is provided at the front end of the mixing vessel 405; the discharge of materials is controlled by an electromagnetic valve installed at the bottom of the mixing vessel 405, and the mixing vessel 405 is lifted by the support rod 406 to facilitate material flow.

[0019] Furthermore, the preparation vessel 401 is connected to the vibrating fluidized bed 403 via a screw conveyor 402, and the vibrating fluidized bed 403 is connected to the mixing vessel 405 via a flow pipe 404; the preparation vessel 401, the vibrating fluidized bed 403 and the mixing vessel 405 are interconnected, thereby maintaining airtightness, eliminating air pollution and meeting environmental protection requirements.

[0020] Example 2 Improvements based on Example 1: A filter plate 5 is embedded inside the mixing vessel 405, and a mixing mechanism 6 is provided on one side of the mixing vessel 405; the filter plate 5 embedded inside the mixing vessel 405 can filter out materials with excessive agglomeration, so as to avoid affecting the uniformity in the later stage.

[0021] Furthermore, the mixing mechanism 6 includes a mounting shell 601, which is embedded in the outer wall of the mixing vessel 405. A Helmholtz coil 602 is embedded inside the mounting shell 601. Simultaneously, activated trace amounts of magnetic nanoparticles are added to the corrosion inhibitor inside the addition tank 407. With the adjustment of the Helmholtz coil 602, a magnetic field is generated to guide the magnetic nanoparticles, thereby controlling the corrosion inhibitor to move directionally along the magnetic field direction and uniformly adsorb onto the surface of the raw material salt. By changing the magnetic field strength, the deposition thickness of the corrosion inhibitor can be precisely controlled to avoid local aggregation and achieve uniformity of the corrosion inhibitor.

[0022] Furthermore, an ultrasonic generator 603 is embedded inside the outer wall of the protective shell 2 corresponding to the outer shell 601, and a transducer 604 is embedded below the preparation vessel 401 inside the protective shell 2. The ultrasonic generator 603 embedded in the protective shell 2, together with the transducer 604, uses wide-wavelength sound waves to achieve resonance of the material throughout the entire field without dead angles, breaking the initial agglomerates of the raw material salt, and at the same time promoting the raw material salt to be more uniformly embedded in the microsphere pores, improving the adhesion of pre-adsorption.

[0023] Furthermore, a through hole 605 is provided at the top of the mounting housing 601, and a mounting cylinder 606 is inserted into the through hole 605; the through hole 605 and the mounting cylinder 606 provide a space for gas flow, allowing external gas to enter the mounting housing 601 to achieve a heat dissipation effect.

[0024] Furthermore, the mounting cylinder 606 has a flow cavity 607 inside, and a filter screen 608 is embedded inside the flow cavity 607. A cooling fan 609 is embedded at the bottom end of the filter screen 608. The mounting housing 601 fixes multiple sets of mounting cylinders 606 through through holes 605. The flow cavity 607 inside the mounting cylinder 606 is fitted with a filter screen 608 and a cooling fan 609. While filtering dust, it improves the fluid flow inside the mounting housing 601, thereby effectively dissipating heat from the Helmholtz coil 602 and the ultrasonic generator 603. Working principle: Raw salt is first introduced into the preparation vessel 401 inside the protective shell 2 through the feeding channel 1. At the same time, modified polystyrene porous microspheres are introduced into the vessel according to a preset ratio through the conveying network 3. The porous structure of the microspheres achieves the initial dispersion and positioning of the raw salt. The polyacrylamide coating on the surface of the microspheres can act as a corrosion inhibitor bridge, guiding the corrosion inhibitor to uniformly fill the pores of the microspheres and cover the surface of the raw salt, thereby avoiding agglomeration and maintaining the uniformity of the coating of the final product. During the mixing process of the mixture by the screw conveyor 402, it is conveyed to the vibrating fluidized bed 403 for drying treatment. Then, under the synergistic action of the conveying power equipment and the flow pipe 404, it enters the mixing vessel 405. Meanwhile, the corrosion inhibitor in the addition tank 407 is conveyed to the mixing vessel 405 through the appropriate conveying power equipment and pipelines, and fully mixed with the raw salt for coating. Finally, the mixture is discharged through the electromagnetic valve installed at the bottom of the mixing vessel 405. The mixing vessel 405 is lifted and installed by a fixed support rod 406 to ensure smooth and unobstructed material flow. The filter plate 5 embedded inside the mixing vessel 405 can effectively intercept materials with excessively large agglomerated particle sizes. Simultaneously, the corrosion inhibitor in the addition tank 407 is pre-mixed with activated trace amounts of magnetic nanoparticles. The ultrasonic generator 603 and transducer 604 embedded in the protective shell 2 work together to achieve full-field resonance of the material using wide-wavelength sound waves. This avoids damage to the particle structure from shear forces and breaks down the initial agglomerates of the raw salt, promoting more uniform embedding of the raw salt into the microsphere pores and improving pre-adsorption adhesion. It also achieves cavitation refinement of the corrosion inhibitor particles, eliminating residual air bubbles in the pores and promoting the interaction between the raw salt and the microspheres. Sufficient contact of the corrosion inhibitor promotes the uniform filling of microsphere pores by trace magnetic nanoparticles and their close adhesion to the surface of the raw salt. Combined with the magnetic field adjustment function of the Helmholtz coil 602, a directional magnetic field can be generated to guide the magnetic nanoparticles, driving the corrosion inhibitor to move directionally along the magnetic field direction, achieving uniform adsorption on the surface of the raw salt. By precisely changing the magnetic field strength, the deposition thickness of the corrosion inhibitor can be accurately controlled, effectively avoiding local aggregation and achieving active directional distribution of the corrosion inhibitor, greatly improving the uniformity of coating. In addition, ultrasonic vibration is transmitted to the filter plate 5, which can redisperse the intercepted agglomerated materials to the qualified particle size and allow them to flow out smoothly. The mounting housing 601 is fixedly assembled with multiple sets of mounting cylinders 606 through through holes 605. Each set of mounting cylinders 606 has a filter screen 608 and a cooling fan 609 embedded in its internal flow cavity 607. The filter screen 608 can effectively filter dust and impurities in the flowing air, preventing dust accumulation inside the equipment from affecting operation. The cooling fan 609 can significantly improve the fluid flow rate inside the mounting housing 601, forming an efficient cooling airflow, thereby producing a good cooling effect on the Helmholtz coil 602 and the ultrasonic generator 603, ensuring the long-term stable operation of the core equipment.
