Description

Technical Field

[0001] This utility model relates to the field of magnesium oxide board production and processing technology, specifically to a screw conveying device for magnesium oxide board powder raw materials. Background Technology

[0002] Magnesium oxide board, also known as magnesium oxide board or magnesium oxychloride board, is a new type of environmentally friendly composite fireproof board. It is mainly composed of a ternary system of magnesium oxide, magnesium chloride, and water, and is reinforced with a medium-alkaline fiberglass mesh and filled with lightweight materials after being formulated and modified. Magnesium oxide board features high strength, large size, fire resistance, moisture resistance, and good water resistance, and is widely used in the building decoration field. In the production of magnesium oxide board, the proportion of different raw materials is crucial to the quality of the final product. For example, the ratio of raw materials such as magnesium oxide, magnesium sulfate, and magnesium chloride needs to be precisely controlled to ensure the product's strength, water resistance, and other performance indicators. To achieve precise metering and proportioning of raw materials, and to ensure continuous and stable material supply, this invention proposes a screw conveyor device for powdered raw materials of magnesium oxide board.

[0003] According to a search, Chinese patent document CN216760368U discloses a feeding device for magnesium oxide board raw materials to improve feeding accuracy. This device uses a vibrating liner installed on the inner wall of the main material storage hopper, driven by an exciter motor to vibrate and discharge the main and auxiliary materials from the hopper. A maintenance door is installed on the feeding pipe for easy cleaning and maintenance at the connection between the feeding pipe and the transfer end pipe. A dredging end connected to an air supply device is also installed on the transfer end pipe, allowing high-pressure gas to be injected into the pipe for dredging, reducing material residue in the feeding device during transport and improving the accuracy of material addition, thereby enhancing the performance of the magnesium oxide board. However, in actual use, the powder easily absorbs moisture and clumps, causing the spiral blades to become stuck or blocked. Furthermore, the spiral blades lack the ability to break up clumps, requiring manual cleaning and shutdown, which affects conveying and production efficiency. In addition, the device's sealing is insufficient; moisture intrusion not only exacerbates powder caking but also affects the overall service life of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screw conveyor for magnesium oxide board powder raw materials, which has the advantages of preventing blockage, breaking up clumps, and strong sealing, thus solving the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw conveying device for magnesium oxide board powder raw materials, comprising a conveying pipe, a drive motor fixedly installed on the left side of the conveying pipe, a coupling and a baffle installed inside the conveying pipe, a main shaft installed inside the baffle, a main screw blade and a secondary screw blade fixedly installed on the outer side of the main shaft, a feed pipe and a discharge pipe fixedly installed on the outer side of the conveying pipe, and a raw material pipe fixedly connected to the top end of the feed pipe.

[0006] Preferably, there are two couplings, and the inner sides of the two couplings are respectively connected to the two ends of the main shaft, and the output shaft of the drive motor is fixedly connected to the left end of one of the couplings.

[0007] With the above technical solution, when the drive motor is started, the output shaft of the drive motor can drive one of the couplings to rotate. This coupling can then drive the main shaft, main helical blades, auxiliary helical blades and another coupling to rotate. The main helical blades and auxiliary helical blades can effectively transport various raw materials to the other end and discharge them from the discharge pipe. In addition, the main helical blades and auxiliary helical blades can also continuously stir and mix the materials, thereby improving the overall production efficiency.

[0008] Preferably, an elastic scraper is fixedly installed on the outer surface of the main helical blade, and multiple secondary helical blades are provided, with crushing teeth on the outer surface of each of the multiple secondary helical blades.

[0009] Through the above technical solution, during the material conveying process of the main spiral blade and the auxiliary spiral blade, the elastic scraper can effectively scrape off the material adhering to the inner wall of the conveying pipe, reduce the accumulation and residue of the material, enable the device to convey the material more smoothly, and improve the conveying efficiency; while multiple auxiliary spiral blades and crushing teeth can crush the lumpy material, making the particle size of the material more uniform, avoiding the formation of blockages in the conveying pipe, ensuring the continuity of material conveying, and also facilitating subsequent processing and handling.

[0010] Preferably, there are two baffles, and each of the two baffles is equipped with a shaft seal.

[0011] Through the above technical solution, the two baffles and shaft seals can effectively prevent material leakage and also effectively ensure the sealing environment inside the conveying pipe, preventing external dust, impurities, etc. from entering its interior. While ensuring the quality of materials, it also reduces the wear of parts and extends the service life of the equipment.

[0012] Preferably, there are multiple feed pipes and multiple raw material pipes, and the multiple feed pipes and raw material pipes are connected by airtight flanges.

[0013] Through the above technical solution, multiple feed pipes and raw material pipes can simultaneously transport different raw materials or materials, increasing the feeding speed and efficiency. They can also transport raw materials in different proportions, making it convenient to flexibly adjust the raw material ratio according to product requirements and produce magnesium oxide boards with different properties and specifications. The airtight flange connection can ensure a good seal at the connection between the feed pipe and the raw material pipe, ensuring the quality of the material, preventing leakage during the transportation process, and reducing material loss and environmental pollution.

[0014] Preferably, a pressure balancing valve and a vibrator are fixedly installed on the outer side of the conveying pipe, and multiple pressure balancing valves and multiple vibrators are provided.

[0015] Through the above technical solutions, multiple air pressure balancing valves can effectively regulate the pressure inside the conveying pipe, avoiding material accumulation or blockage due to unstable pressure. The vibrator can make the material more evenly distributed during the conveying process, preventing the formation of dead zones or accumulation of material, making the material conveying process smoother and improving the working efficiency of the equipment.

By starting the drive motor, the output shaft of the drive motor can drive one of the couplings to rotate. This coupling, in turn, drives the main shaft, main spiral blades, auxiliary spiral blades, and another coupling to rotate. The main and auxiliary spiral blades not only effectively transport the material to the other end and discharge it, but the elastic scraper can also effectively scrape off the material adhering to the inner wall of the conveying pipe, reducing material accumulation and residue, enabling the device to transport materials more smoothly and improving conveying efficiency.
