Description

Technical Field

[0001] This utility model relates to the field of sand mixing technology for coated sand, and more particularly to a sand mixing device for casting coated sand. Background Technology

[0002] Sand mixing devices for producing coated sand are commonly used in casting processes, especially in the production of cast iron or other metal parts. They utilize the unique properties of coated sand to ensure the surface quality and precision of the castings. Coated sand refers to sand grains coated with a thin film material, usually resin or other chemical substances, which improves the adhesion between the sand grains, thereby enhancing the strength and refractoriness of the sand mold.

[0003] Basic components and working principle of sand mixing equipment for producing coated sand:

[0004] Sand mixing cylinder (or sand mixing tank): This is the core part of the device, responsible for mixing sand and coating material. The sand can be mixed inside the cylinder by mechanical stirring or airflow to ensure that the sand particles are evenly coated with the coating material.

[0005] Drive system: Sand mixing devices are typically equipped with electric motors or other drive devices to provide the mixing motion. Common drive methods include electric agitation, pneumatic agitation, or mixing using centrifugal force.

[0006] Coating material addition device: This is a system that uniformly adds coating materials (such as resin, binder, etc.) into the sand. Precise addition of coating materials can be achieved through a spray system, liquid pump, or automatic batching system. This ensures that the proportion of coating materials meets casting requirements.

[0007] Heating system: In order to enable the coating material to adhere better to the surface of the sand, some devices are equipped with a heating system to heat the coating material or sand and promote the coating reaction.

[0008] Exhaust and dust removal systems: The sand mixing process generates some dust, especially when using chemical materials such as resins, which may release harmful gases. Therefore, the equipment is usually equipped with exhaust and dust removal systems to ensure a safe and clean environment.

[0009] Automated control system: In order to improve efficiency and consistency, modern sand mixing equipment is often equipped with an automated control system, which can control the mixing time, temperature, and proportion of coating material in real time to ensure the stable quality of sand.

[0010] Working process of the sand mixing unit:

[0011] Sand input: First, dry sand, recycled sand or other types of sand are fed into the sand mixing device.

[0012] Input of coating material: According to the casting requirements, the coating material is precisely added through a metering system, which is usually liquid resin, grease or other chemical material.

[0013] Mixing: Activate the drive system to mix, ensuring the coating material is evenly applied to each grain of sand. The mixing method varies depending on the equipment design and may include efficient mechanical mixing or airflow mixing.

[0014] Heating and curing: Some sand mixing devices can be equipped with a heating element to cause a chemical reaction between the sand and the coating material (such as the curing of resin), making the coating layer more robust.

[0015] Output: The mixed and coated sand is eventually sent to a sand storage silo or used in the casting process.

[0016] In the prior art, a sand mixing device for casting coated sand can be used normally, but it cannot be positioned and fixed well during use, and it is not convenient to disassemble and assemble it easily.

[0017] Therefore, we propose a sand mixing device for casting coated sand. Utility Model Content
