Description

Technical Field

[0001] This utility model belongs to the technical field of dilution devices, specifically a dilution device for the production of polyurethane water-based anti-corrosion coatings. Background Technology

[0002] With the continuous development of industrial technology, anti-corrosion coatings are being used more and more widely in various fields, especially in marine engineering, shipbuilding, chemical equipment, bridge construction, and other fields with high requirements for anti-corrosion performance. The main function of anti-corrosion coatings is to protect the substrate from the erosion of corrosive media and extend the service life of materials. Among the many types of anti-corrosion coatings, water-based anti-corrosion coatings have gradually become the mainstream choice in the market due to their advantages such as environmental protection and low VOC emissions. Water-based anti-corrosion coatings use water as a dispersion medium, which not only reduces environmental pollution but also reduces safety hazards during construction. However, dilution is a crucial step in the production process of water-based anti-corrosion coatings. The purpose of dilution is to adjust the viscosity of the coating to achieve the consistency required for construction, thereby ensuring uniform coating and good adhesion performance on the substrate surface.

[0003] Existing dilution equipment for the production of polyurethane water-based anti-corrosion coatings has the following main shortcomings:

[0004] In existing dilution devices used in the production of polyurethane water-based anti-corrosion coatings, manual measurement of the diluent based on experience is required. This method makes it difficult to accurately control the dilution ratio. Different batches of products may experience fluctuations in viscosity, drying time, and anti-corrosion performance due to variations in the dilution ratio, affecting product consistency and stability. This fails to meet customers' requirements for uniform product quality, resulting in inconsistent product quality. Furthermore, the coating tends to accumulate on the container walls, especially in corners and edges where it is difficult to stir. This prevents the coating in these areas from fully mixing with the diluent, leading to uneven dilution in certain areas. Some areas are over-diluted, while others are under-diluted, ultimately affecting the overall performance and quality. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a dilution device for the production of polyurethane water-based anti-corrosion coatings, which solves the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dilution device for the production of polyurethane water-based anti-corrosion coating, comprising a box body, a stirring structure provided at the center of the inside of the box body, a dilution structure provided at the center of the upper end face of the box body on the other side, a discharge pipe provided at the center of the lower end face of the box body, and a discharge structure provided at the center of the inside of the discharge pipe.

[0007] The stirring structure includes a stabilizing frame, which is located at the front center of the upper end face of the box. A first motor is located at the center of the upper end face of the stabilizing frame. A first gear is fixedly connected to the output end of the first motor. The first gear is located at the center inside the stabilizing frame. A second gear is located at the rear end of the first gear. The second gear is located at the center of the upper end face of the box. The first gear and the second gear mesh with each other. A rotating rod is sleeved at the center of the inner side wall of the second gear.

[0008] As a further embodiment of this utility model: a bolt is threadedly connected to the center of the upper end face of the rotating rod, and one end of the rotating rod passes through the upper end face of the box and extends into the inside of the box.

[0010] As a further embodiment of this utility model: the dilution structure includes a diluent placement box, which is located at the center of the upper end of the box body near one side. A peristaltic pump is provided at the center of the lower inner wall of the diluent placement box. An output pipe is fixedly connected to the output end of the peristaltic pump. The output end of the output pipe passes through the lower inner wall of the diluent placement box and the upper end of the box body to the inside of the box body. A flow meter is sleeved at the center of the outer wall of the output pipe.

[0011] As a further embodiment of this utility model: the discharge structure includes a connecting frame, which is located at the upper center of one side wall of the discharge pipe. A second motor is provided at the center of one side wall of the connecting frame.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A dilution apparatus for producing polyurethane water-based anti-corrosion coatings includes:

[0025] Box 1 has a control panel 2 located on one side near the bottom. A feed hopper 3 is located at the center of the upper surface of box 1, near one side. A stirring structure 4 is located at the center of the interior of box 1. A dilution structure 5 is located at the center of the upper surface of box 1, near the other side. A discharge pipe 6 is located at the center of the lower surface of box 1, and a discharge structure 7 is located inside the discharge pipe 6. The stirring structure 4 includes a stabilizing frame 401, which is located at the front center of the upper surface of box 1. A first motor 402 is located at the center of the upper surface of the stabilizing frame 401. A first gear 403 is fixedly connected to the output end of the first motor 402, and the first gear 403 is mounted on the stabilizing frame 401. At the center of the interior, a second gear 404 is provided at the rear end of the first gear 403. The second gear 404 is located at the center of the upper end face of the box 1. The first gear 403 and the second gear 404 mesh with each other. A rotating rod 406 is sleeved at the center of the inner side wall of the second gear 404. A bolt 405 is threadedly connected to the center of the upper end face of the rotating rod 406. One end of the rotating rod 406 passes through the upper end face of the box 1 and extends into the interior of the box 1. Scrapers 407 are provided on both sides of the upper part of the outer side wall of the rotating rod 406. The two scrapers 407 are adapted to the inner side wall of the box 1. A spiral stirring blade 408 is sleeved at the center of the outer side wall of the rotating rod 406.

[0026] By starting the first motor 402, the first gear 403 is driven to rotate. Since the first gear 403 and the second gear 404 mesh with each other, the rotation of the first gear 403 drives the second gear 404 to rotate. A rotating rod 406 is sleeved at the center of the inner side wall of the second gear 404. Therefore, the rotating rod 406 starts to rotate with the rotation of the second gear 404. As the rotating rod 406 rotates, the scraper 407 continuously scrapes the inner side wall of the box 1, which can effectively prevent the paint from adhering and accumulating on the inner wall of the box 1, ensuring that the paint is mixed evenly and that no paint residue dries on the wall of the box 1, affecting the product quality. At the same time, the spiral stirring blade 408 sleeved at the center of the outer side wall of the rotating rod 406 also starts to rotate. The spiral stirring blade 408 stirs and mixes the paint and diluent in the box 1, so that the two are in full contact and mixed evenly.

[0027] The dilution structure 5 includes a diluent placement tank 501, which is located at the center of the upper end of the tank body 1 on one side. A peristaltic pump 502 is provided at the center of the lower inner wall of the diluent placement tank 501. An output pipe 503 is fixedly connected to the output end of the peristaltic pump 502. The output end of the output pipe 503 passes through the lower inner wall of the diluent placement tank 501 and communicates with the upper end of the tank body 1 to the inside of the tank body 1. A flow meter 504 is sleeved at the center of the outer wall of the output pipe 503.

[0028] When the polyurethane water-based anti-corrosion coating needs to be diluted, the peristaltic pump 502 is started. The peristaltic pump 502 can continuously and stably draw out the diluent from the diluent storage tank 501. The peristaltic pump 502 delivers the drawn diluent through the output pipe 503, allowing the diluent to smoothly enter the tank 1 and mix with the polyurethane water-based anti-corrosion coating. During the delivery, the flow meter 504 can measure and display the flow rate of the diluent in real time. The operator can control the working status of the peristaltic pump 502 through the control panel 2 according to the amount of coating and the required dilution ratio, so as to accurately add the appropriate amount of diluent and ensure the accuracy of the dilution effect.

[0029] The discharge structure 7 includes a connecting frame 701, which is located at the upper center of one side wall of the discharge pipe 6. A second motor 702 is located at the center of one side wall of the connecting frame 701. The output end of the second motor 702 passes through one side wall of the connecting frame 701 and the side wall of the discharge pipe 6 and extends into the discharge pipe 6. A valve plate 703 is fixedly connected to the end of the second motor 702. Four sliding grooves 704 are arranged in a ring on the lower end face of the housing 1. Four limiting blocks 707 are arranged in a ring on the lower end face of the housing 1. A sliding block 705 is slidably connected to the center of each of the four sliding grooves 704. Three filter screens 706 are arranged vertically between the four sliding blocks 705. The three filter screens 706 have filter holes of different sizes. The four limiting blocks 707... 07 is threadedly connected to the lower end face of the four limit blocks 707. When the diluted paint needs to be discharged, the second motor 702 is started to rotate, driving the valve plate 703 to rotate, thereby controlling the opening and closing of the discharge pipe 6 to realize the discharge and stop of the mixed paint. When the diluted paint flows out of the box 1 through the discharge pipe 6, some impurities in the paint can be filtered out by three different sized filter screens 706, so that the quality of the discharged finished product is higher. In addition, the limit blocks 707 are used to limit the position of the sliding block 705 to prevent the sliding block 705 from sliding excessively and disengaging from the sliding groove 704, ensuring that the filter screen 706 is always in the correct position, so as to always play an effective filtering role.

[0030] The working principle of this utility model is as follows: After the polyurethane water-based anti-corrosion coating enters the box 1 through the feed hopper 3, the first motor 402 is started to drive the first gear 403 fixedly connected to it to rotate. Since the first gear 403 and the second gear 404 mesh with each other, according to the gear transmission principle, the rotation of the first gear 403 will drive the second gear 404 to rotate synchronously. A rotating rod 406 is sleeved at the center of the inner side wall of the second gear 404. Therefore, the rotating rod 406 will start to rotate with the rotation of the second gear 404. The scrapers 407 provided on the upper sides of the outer side wall of the rotating rod 406 will rotate together with the rotating rod 406. 07 is adapted to the inner wall of the box 1. During rotation, it continuously scrapes the inner wall of the box 1, effectively preventing the paint from adhering and accumulating on the inner wall of the box 1. This ensures that all paint can participate in the subsequent mixing process, thereby ensuring that the paint is mixed evenly and avoiding the impact of some paint residue drying on the wall of the box 1 on product quality. At the same time, the spiral stirring blade 408 fitted at the center of the outer wall of the rotating rod 406 also begins to rotate, playing a stirring role on the paint in the box 1. The spiral stirring blade 408, through its own spiral structure, continuously turns the paint in the box 1, promoting full flow of the paint and creating conditions for better mixing with the diluent to be added.

[0031] When the polyurethane water-based anti-corrosion coating enters the tank 1, the peristaltic pump 502 is started. The peristaltic pump 502 can continuously and stably draw out the diluent from the diluent storage tank 501 and deliver it to the inside of the tank 1 through the output pipe 503. The flow meter 504, which is sleeved at the center of the outer wall of the output pipe 503, can measure and display the flow information of the diluent in real time. The operator can use the control panel 2 located on the lower side of the tank 1 to adjust the working status of the peristaltic pump 502 according to the actual amount of coating and the required dilution ratio, etc., to accurately control the amount of diluent added to the tank 1, so as to achieve the purpose of precise dilution and ensure that the dilution effect meets the production requirements. That is, by adjusting the peristaltic pump 502, the addition speed and total amount of diluent can be controlled so that the ratio of coating to diluent reaches the expected value, ensuring the stable performance of the final product.

[0032] After the paint and diluent are thoroughly mixed in the tank 1, the mixed paint needs to be discharged to proceed to the next production process. At this time, the second motor 702 is activated, driving the valve plate 703, which is fixedly connected to it, to rotate inside the discharge pipe 6. The rotation of the valve plate 703 controls the opening and closing of the discharge pipe 6. When the valve plate 703 rotates to a specific angle, the discharge pipe 6 is in a conductive state, and the mixed paint flows out of the tank 1 through the discharge pipe 6. During the paint discharge process, four sliding grooves 704 arranged in a ring on the lower end face of the tank 1 are each slidably connected to sliding blocks 705. The four sliding blocks 705... Three filter screens 706 are arranged vertically, with different sizes of filter holes. These screens can filter the outflowing paint in stages, intercepting impurities of various sizes in the paint in turn, effectively improving the quality of the discharged finished paint. Four limiting blocks 707 are threadedly connected to corresponding positions to limit the position of the sliding block 705. This prevents the sliding block 705 from sliding excessively out of the sliding groove 704 under the action of external forces such as paint flow impact, ensuring that the filter screens 706 are always in the correct and stable position, thus always playing an effective filtering role and ensuring the reliability and stability of the filtration effect.

[0033] Furthermore, the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
