Description

Technical Field

[0001] This utility model relates to the technical field of waste gas collection devices, specifically a waste gas collection device for a knitting needle quenching furnace. Background Technology

[0002] With the rapid development of the textile machinery industry, knitting needle quenching furnaces, as key heat treatment equipment, play a vital role in improving the hardness and wear resistance of knitting needles. However, during the quenching process, the rapid cooling of metal components generates a large amount of waste gas, which contains harmful substances such as oil mist, dust, and volatile organic compounds, posing a potential threat to the environment and human health. With increasingly stringent national environmental regulations and rising public awareness of environmental protection, enterprises face increasing environmental pressure. To achieve green production and reduce pollution emissions, enterprises urgently need to adopt effective waste gas collection and treatment measures. The waste gas collection device for knitting needle quenching furnaces is designed to address this need. It can effectively collect and treat the waste gas generated during the quenching process, reducing environmental pollution. In conclusion, the research and application of waste gas collection devices for knitting needle quenching furnaces is an inevitable trend for green production and environmentally friendly development in the textile machinery industry. Through continuous design optimization, performance improvement, and service enhancement, this device will make a significant contribution to the sustainable development of the textile machinery industry.

[0003] Chinese Patent Publication No. CN208917253U discloses a device for collecting organic waste gas from a pit-type quenching furnace. The furnace opening is covered by a waste gas collection shell, which sits on the ground. The top has two closable covers, an upper left cover and an upper right cover. When closed, the upper left cover and upper right cover seal the upper part of the waste gas collection shell, creating a sealed space inside. Several extraction ports are installed on the sides of the waste gas collection shell, each connected to a suction pump via a connecting pipe. The suction pump is connected to the outside via an exhaust pipe. The suction pump extracts gas from the waste gas collection shell and discharges it through the exhaust pipe. A pressure compensation hole is provided on the waste gas collection shell, and a one-way valve is installed on the pressure compensation hole. The one-way valve allows gas to enter the waste gas collection shell but not vice versa. This invention has the advantages of simple structure and effective removal of volatile waste gas from pit-type quenching furnaces.

[0004] However, this utility model has the following problems in actual use:
