The utility model discloses an argon gas inlet device, which relates to the technical field of welding, and comprises a conveying mechanism arranged at the gas outlet end of an argon gas tank, and further comprises a flow regulating mechanism, the flow regulating mechanism comprises a fixed plate, the fixed plate is arranged at one end of the inside of the conveying mechanism, and a mounting rod is arranged on the inner wall of the fixed plate. The outer side of one end of the mounting rod is sleeved with a movable plate, the inner wall of the fixed plate and the inner wall of the movable plate are each provided with three through holes, and a sealing gasket is arranged at one end of the fixed plate. The gas conveying pipe can be connected with an outlet flange of an argon tank through the connecting bolt, the servo motor enables the movable plate to rotate, and the corresponding relation between the three through holes in the inner wall of the movable plate and the three through holes in the inner wall of the fixed plate can be adjusted; the flow of argon can be adjusted by adjusting the size of the communicating part between the through holes, and the argon inlet amount can be conveniently controlled according to requirements.

In order to solve the problems that in the prior art, when a gas stirring device is adopted for stirring an anoxic tank, dissolved oxygen is likely to exceed the standard, only vertical stirring is adopted, dead zones are likely to be generated, and sludge and water are not fully mixed, the invention provides a gas stirring method for the anoxic tank for sewage treatment. And meanwhile, gas is intermittently supplied to the gas stirring pipe, and the gas inlet amount of the stirred gas is controlled, so that a good stirring effect can be realized only by introducing a small amount of gas into the anoxic tank, and the problem that the dissolved oxygen amount exceeds the standard due to excessive introduced gas is solved.

The utility model discloses a nozzle cover of an air textured yarn processing machine. The nozzle cover comprises a fixing block and a stand column installed at one end of the fixing block. A mounting block is arranged at one end of the fixing block and arranged on one side of the stand column. An adjusting assembly is hinged to one end of the mounting block and comprises an adjusting block movably connected to one end of the mounting block, and a plug is connected to the side, close to the fixing block, of one end of the adjusting block in a matched mode; an air inlet is formed in the fixed block; a nozzle is arranged at one end of the air inlet; the rotating angle of the adjusting block is flexibly adjusted through the rotating shaft, so that the dislocation angle of the plug and the nozzle is accurately controlled, then the air inlet amount of the air inlet hole is accurately adjusted, the machining efficiency of the air textured yarn is improved, the plug is located over the nozzle, blown air is collided back, turbulent flow is formed in the nozzle, and the machining efficiency of the air textured yarn is improved. The hair feeling of the yarn is changed according to the size of the turbulent flow, and the hair feeling of the air-jet texturing yarn can be controlled according to the height of the plug.

This invention provides an active air intake grille, belonging to the field of automotive component technology, comprising: a grille body, the grille body having an arcuate structure; a flexible shaft, the flexible shaft being bent wholly or partially according to the arcuate shape of the grille body, and the flexible shaft being rotatably mounted on the grille body; a blade assembly, the blade assembly including at least two grille blades, each of the grille blades being arranged according to the arcuate shape of the grille body, each of the grille blades being connected to the flexible shaft, and the flexible shaft driving each of the grille blades to rotate when rotated; it also relates to an automobile, including an active air intake grille. The beneficial effect of this invention is that, based on setting the grille body as an arcuate structure, the flexible shaft can synchronously drive each grille blade arranged in an arcuate plane on the grille body to rotate, thereby achieving the purpose of non-linear transmission.

The utility model relates to laboratory powder spraying equipment capable of preventing static interference. The laboratory powder spraying equipment comprises a cabinet body and a small-dose powder outlet spray gun system, a powder feeding cavity, a middle cavity and a powder collecting cavity are formed in the cabinet body. Plastic plates are arranged on the top face, the left side face, the right side face and the bottom face of the powder feeding cavity. The small-dose powder discharge spray gun system comprises a fluidization cylinder, and the powder storage amount of the fluidization cylinder is 10-150 g. A powder outlet of the Venturi powder pump is connected with the spray gun; the powder adjusting mechanism is suitable for adjusting the concentration amount of the powder pumped out by the powder pumping pipe. According to the laboratory powder spraying equipment capable of preventing electrostatic interference, the plastic plate is arranged in the powder feeding cavity, so that electrostatic interference caused by electric conduction of metal plates on the periphery to electrostatic spraying is avoided, metal powder is close to spraying on a production line when a sample plate is sprayed in a laboratory, and the accurate powder spraying effect is achieved; and the quality inspection accuracy of a sample plate manufactured in a laboratory is ensured. On the premise of ensuring the accuracy, the equipment is very convenient to use and clean afterwards.

The invention belongs to the technical field of nursing machine nozzles, and discloses a clothes nursing machine built-in ultrasonic decontamination nozzle which comprises a conveying pipe, a clothes hanging groove is formed in the top end of the conveying pipe, and an air inlet mechanism is arranged in a nozzle body. The device can drive the first connecting rod to rotate by rotating the hand lever, so that the space through which water passes is compressed, but the conveying power of the conveying pump is not changed, under the same conveying power, the smaller the conveying pressure of the space is, the higher the conveying pressure is, and when water pressure needs to be reduced, the conveying plug is moved upwards, so that the water can be conveyed according to the designed conveying space; and the water pressure when water passes through can be further reduced when the space is expanded upwards, so that the clothes cannot be damaged when the device is used for nursing and decontaminating some clothes which are easy to loosen, and the aim of adjusting the decontaminating force according to the specific material of the clothes by adjusting the water pressure is achieved.
