Description

Technical Field

[0001] This utility model relates to the field of casting coating production equipment, and in particular to an alcohol-based casting coating stirring and preparation device. Background Technology

[0002] Alcohol-based coatings are pastes or powders made from various refractory materials, binders, suspending agents, and thixotropic agents. They are then diluted with organic agents such as ethanol and isopropanol to form coatings with certain density, viscosity, suspension, and thixotropic properties. They are used to coat sand molds or sand cores to prevent sand from sticking to the castings. Alcohol-based coatings are suitable for various self-hardening sands and water glass sands. They can be used for small and medium-sized cast steel parts as well as large cast iron parts. The coatings are suitable for various cast iron, cast steel, and cast aluminum. They need to be stirred evenly as needed before use.

[0003] Alcohol-based casting coatings are key materials in casting production, mainly composed of refractory aggregates, binders, solvents (ethanol, etc.), and additives. Their mixing uniformity directly affects the coating strength, permeability, and anti-sand adhesion ability. Existing mixing and preparation devices suffer from poor mixing and scraping effects. Traditional mixing devices often employ a single mixing structure, which easily leads to localized material accumulation during mixing, resulting in uneven mixing. This is especially true for raw materials in different forms such as pastes and powders, making it difficult to achieve full integration. Furthermore, the devices lack effective scraping functions, affecting coating quality. Therefore, we propose an alcohol-based casting coating mixing and preparation device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an alcohol-based casting coating stirring and preparation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An apparatus for preparing alcohol-based casting coatings includes a preparation cylinder. A scraper is fixedly connected to the outer surface of the preparation cylinder.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-5In this utility model, an alcohol-based casting coating stirring and preparation device includes a preparation cylinder 1. A scraper 3 is fixedly connected to the outer surface of the preparation cylinder 1. A reduction motor 9 is fixedly mounted on the bottom surface of the preparation cylinder 1 via a frame. A rotating shaft 10 is fixedly connected to the output end of the reduction motor 9. A stirring component 11 is fixedly connected to the outer surface of the rotating shaft 10. Multiple crushing teeth 13 are fixedly connected to the top of the outer surface of the stirring component 11. A feeding cylinder 4 is fixedly embedded in the upper surface of the preparation cylinder 1, and the crushing teeth 13 are located inside the feeding cylinder 4. The scraper 3 includes an electric push rod 301 fixedly connected to the outer surface of the preparation cylinder 1. A transmission frame 302 is fixedly connected to the output end of the electric push rod 301. Two transmission frames are fixedly connected to the outer surface of the transmission frame 302. The bottom end of each transmission rod 303 penetrates through the preparation cylinder 1 and extends into the interior of the preparation cylinder 1. The bottom ends of the two transmission rods 303 are fixedly connected to a circular scraper ring 304. A dispersing disc 12 is fixedly connected to the outer surface of the rotating shaft 10. The inner diameter of the circular scraper ring 304 is set to be larger than the outer diameter of the stirring element 11, so that the rotation of the stirring element 11 will not affect the up-and-down movement of the circular scraper ring 304, thus ensuring the feasibility of the device. The reduction motor 9 drives the rotating shaft 10, so that the stirring element 11, the crushing teeth 13 and the dispersing disc 12 can stir, crush and disperse the material. The scraper 3 can effectively remove the material from the inner wall of the preparation cylinder 1, ensuring that the subsequent stirring is more uniform, improving the quality of the coating and making the coating more uniformly mixed.

[0024] A discharge pump 6 is fixedly installed on the outer surface of the preparation cylinder 1. The input end of the discharge pump 6 is connected to the preparation cylinder 1, and a discharge pipe 5 is fixedly installed on the output end of the discharge pump 6. The discharge pump 6 and the discharge pipe 5 can quickly discharge the prepared coating, avoiding the tedious operation of manual discharge and improving discharge efficiency. A support base 8 is fixedly connected to the bottom surface of the preparation cylinder 1, and an observation window 2 is provided on the outer surface of the preparation cylinder 1. The support base 8 provides stable support for the preparation cylinder 1, ensuring that the device will not shake or tip over during operation. The observation window 2 allows the operator to observe the stirring, scraping and mixing of the material in the preparation cylinder 1 in real time.

[0025] A controller 7 is fixedly connected to the outer surface of the preparation cylinder 1. The controller 7 is electrically connected to the electric push rod 301 and the geared motor 9 via wires. The controller 7 realizes intelligent control of the electric push rod 301 and the geared motor 9. The operator can precisely adjust the stirring speed and scraping frequency according to different coating formulas and preparation processes. The operation is simple and the control is precise. The stirring component 11 includes multiple stirring rods 111 fixedly connected to the outer surface of the rotating shaft 10 and two bottom scrapers 112 fixedly connected to the outer surface of the rotating shaft 10. The bottom scrapers 112 are in contact with the inner bottom wall of the preparation cylinder 1. During the stirring process, the stirring rods 111 continuously stir the material, so that different raw materials are stirred together. With full contact and mixing, the bottom scraper 112 rotates with the rotating shaft 10, scraping up the material adhering to the bottom of the preparation cylinder 1 and re-engaging it in the mixing. For example, the bottom scraper 112 effectively prevents the coating from accumulating at the bottom, ensuring that the composition of the coating in the entire cylinder is uniform. The outer surface of the feeding cylinder 4 is fixedly connected to a ring guide rail 14, and multiple sliding connecting rods 15 are slidably connected inside the ring guide rail 14. The bottom end of each sliding connecting rod 15 is fixedly connected to the outer surface of the rotating shaft 10. The ring guide rail 14 and the sliding connecting rods 15 cooperate to provide stable support and guidance for the rotating shaft 10, enhance the stability of the rotating shaft 10 when rotating, and reduce uneven mixing and equipment wear caused by shaking.

[0026] The working principle of this utility model is as follows:

[0027] In preparing alcohol-based casting coatings, powdered refractory materials, binders, and other raw materials are added to the preparation cylinder 1 through the feeding cylinder 4. Simultaneously, the reduction motor 9 is started, and the rotating shaft 10 drives the stirring component 11, the crushing teeth 13, and the dispersing disc 12 to rotate at high speed. First, when adding the raw materials, the crushing teeth 13 crush larger particles, which then fall to the bottom. Next, the stirring component 11 and the dispersing disc 12 thoroughly stir and disperse the materials. At the same time, the electric push rod 301 is activated, and the transmission frame 302 drives the transmission rod 303 and the circular scraper ring 304 to move along the inner wall of the preparation cylinder 1, scraping off any adhering materials. This ensures more uniform mixing of the coating during preparation, improving the coating quality.
