Technical Field
[0001] This utility model relates to the field of die casting machine exhaust gas treatment, and in particular to a die casting machine exhaust gas treatment device with high collection efficiency. Background Technology
[0002] With the rapid development of industries such as automobiles, motorcycles, home appliances, and 3C electronics, die casting technology has been widely used in the field of metal parts processing due to its advantages of efficient molding and mass production. During the operation of the die casting machine, when the molten metal comes into contact with the mold, the high-temperature decomposition of the release agent will generate complex waste gases including metal dust (such as aluminum and zinc oxides), oil fumes, VOCs (volatile organic compounds), and oil mist. These waste gases will not only cause the workshop environment to be smoky and the equipment to be greasy and corroded, but will also harm the respiratory health of the operators. Long-term emissions will aggravate air pollution. Traditional die casting machine waste gas treatment devices generally have problems such as fixed collection distance leading to low capture efficiency, inconvenient disassembly and assembly of filter components, and insufficient sealing performance, making it difficult to adapt to the waste gas treatment needs under different working conditions.
[0003] Therefore, those skilled in the art have provided a high-efficiency die-casting machine exhaust gas treatment device to solve the problems mentioned in the background art. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a high-efficiency die-casting machine exhaust gas treatment device. The collection box can be moved flexibly by a drive motor in conjunction with a threaded rod and a sliding rod, which can capture exhaust gas at close range to improve collection efficiency. The three-stage filter plate in the filter box, consisting of stainless steel mesh, PTFE membrane filter material and activated carbon fiber material, achieves graded purification. The filter plate slides with the filter box through a sliding groove, which facilitates disassembly and maintenance.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency die-casting machine exhaust gas treatment device includes a collection box, a filter box at the top of the collection box, a connecting pipe at the top of the filter box, fixing plates on both sides of the filter box, a fixing shell at the top of one fixing plate, a drive motor inside the fixing shell, a threaded rod inside one fixing plate, and a sliding rod inside the other fixing plate. A first filter plate is installed at the top of the filter box, a third filter plate is installed at the bottom of the filter box, a second filter plate is installed in the middle of the filter box, and stretchable cloths are installed around the bottom of the filter box and the bottom of the collection box. The above technical solution realizes the integrated design of waste gas collection, graded filtration and sealing protection. The components work together to ensure the flexibility of collection and to purify different pollutants in a targeted manner.

With the above technical solution, the filter plate can be quickly pulled out and disassembled along the slide groove without complicated tools, which makes it convenient for staff to clean and replace the filter material regularly, reducing maintenance labor intensity and minimizing the impact on production.
[0009] Furthermore, the fixed shell is fixed to the upper part of one side fixed plate, and the inner wall of the fixed shell is fixed to the outer wall of the drive motor; The above technical solution achieves a stable installation of the drive motor, preventing vibration during operation that could cause structural loosening. At the same time, the fixed housing protects the drive motor, isolates it from exhaust gas corrosion, extends the motor's service life, and ensures the stability of equipment operation.
