The invention relates to the technical field of waste gas treatment of air jet looms, in particular to a waste gas port pressurization adjusting device applied to an air jet loom, which comprises a main frame, a height-adjustable waste gas guide cover is fixedly assembled at the position of a waste gas port of the main frame, and an electric control type lifting guide machine is arranged in the waste gas guide cover. According to the waste gas port pressurization adjusting device applied to the air jet loom, control is automatically carried out according to the angle of internal air pressure, and energy consumption is reduced; the waste gas of the air jet loom can be guided and recycled through the height-adjustable waste gas guide cover at the position of the waste gas port of the main frame, so that the resource waste is reduced, and the external environment is improved; the height of the waste gas flow guide cover is adjusted in an internal and external lifting mode, the electric control type lifting flow guide machine is arranged in the waste gas flow guide cover, air guided into the waste gas flow guide cover can be injected after secondary pressurization, the secondary injection pressure is increased, and the utilization effect is guaranteed.

The invention provides plug anomaly detection equipment. The plug anomaly detection equipment comprises a plug detection system, a cooling system and a data processing system, the cooling system is used for cooling the plug detection system and the plug working environment; the plug detection system comprises a visual unit used for shooting plug images; the visual unit is in communication connection with the data processing system; and the data processing system comprises a data preprocessing unit, a plug falling detection unit, a plug surface flaw detection unit and an alarm unit, and is used for data acquisition, data processing, plug falling and surface flaw detection when the plug works. The method comprises the following steps: preprocessing original point cloud data to obtain preprocessed point cloud data, and segmenting the preprocessed point cloud data to obtain header data; and then plug falling detection is carried out, if the plug does not fall, plug surface flaw detection is carried out, and if the plug falls, the steps of data preprocessing and plug falling detection are repeated.

This utility model discloses a high-efficiency denitrification wastewater treatment device based on A2O. The internal space of the tank is divided into an equipment room, an influent tank, an anaerobic tank, an anoxic tank, an aerobic tank, a sedimentation tank, and a filtration tank by a partition. The sedimentation tank is equipped with a sludge return device and is connected to the anaerobic tank through the sludge return device. A plug flow zone is located in the middle of the anoxic tank, and an air-lift plug flow device is installed in the plug flow zone, dividing the anoxic tank into a first anoxic section and a second anoxic section. A drainage hole is provided on the partition between the aerobic tank and the sedimentation tank. A return hole is opened on the partition near the anoxic tank at the output end of the aerobic tank, and the output end of the aerobic tank is connected to the first anoxic section through the return hole. The area of ​​the return hole is larger than the area of ​​the drainage hole. This utility model can reduce the impact of wastewater influent load, improve wastewater treatment capacity, and reduce energy consumption.

The utility model belongs to the technical field of cleaning devices, and particularly relates to a lower copper bar chain quick cleaning device which comprises a bottom groove frame and a top groove frame, the bottom groove frame and the top groove frame are the same in specification, the rear ends of the bottom groove frame and the top groove frame are connected through a hinge, and a lower rotating shaft is rotationally connected to the middle of an inner cavity of the bottom groove frame in the horizontal direction. A lower friction roller is fixedly inserted into the middle of the lower rotating shaft, a lower driving gear is fixedly inserted into the end part of the lower rotating shaft, two lower driven shafts are symmetrically and rotationally connected to two sides of the lower rotating shaft, lower driven gears are fixedly inserted into the end parts of the two lower driven shafts, and the lower driving gear is in meshed connection with the two lower driven gears. The four roller brushes are driven by the two friction rollers to clean the upper surface and the lower surface of the copper bar chain in a rolling mode through transmission force of the copper bar chain, and the tangent rotation direction of the lower roller brush and the tangent rotation direction of the upper roller brush are opposite to the moving direction of the lower copper bar chain. Therefore, the surface of the lower copper bar chain and gaps at the chain joints can be deeply cleaned better.
