Aluminum alloy tuyere

Abstract

The invention discloses an aluminum alloy tuyere comprising a tuyere body; a mounting base is fixedly connected to the top of the tuyere body; when a tuyere cover plate is assembled, a tuyere cover is pushed, and handles are pulled, so that movable rods drive clamping rods to be separated from clamping grooves, movable plates move, then clamping blocks enter the clamping grooves, and extrusion blocks are pushed to move; when penetrating grooves and the clamping rods are located on the same straight line, the handles are loosened, the clamping rods enter the penetrating grooves, the handles are pushed to enable the clamping rods to enter the grooves, the handles are rotated to enable the clamping rods to rotate by 90 degrees, the handles are loosened, second springs enable the clamping rods to enter the limiting grooves, and the clamping blocks are limited; and the clamping blocks are limited through the action of the second springs in cooperation with the clamping rods and the limiting grooves, so that the situation that the tuyere cover plate falls off or shakes due to the fact that the tuyere shakes due to movement of a motor, a fan and the like in use is greatly avoided, and the situation that noise is generated due to shaking of the tuyere cover plate under the situation that the tuyere cover plate is not stably fixed is avoided.

Description

technical field [0001] The invention relates to the field of aluminum alloy tuyere, in particular to an aluminum alloy tuyere. Background technique [0002] Aluminum alloy tuyere, used for air supply and return air in ventilation and air conditioning systems, can be installed directly at the end of the pipe or on the ceiling or on the wall or door. Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for welded structural parts of aluminum alloys is increasing, and the research on the weldability of aluminum alloys is also in-depth. The wide application of aluminum alloy has promoted the development of aluminum alloy welding technology, and the development of welding technology has expanded the application field of ...

Problems solved by technology

[0003] This application is improved under the prior art. In the prior art, the air supply outlet of the common dust-free workshop is a high-efficiency purification air supply outlet. For filtering, the clean room needs to ensure that the environment is clean and sterile, and the air sent into the clean room needs to be purified in advance. Secondly, the aluminum alloy tuyere for plasma spraying is mostly assembled with bolts. Under the use of fans, etc., The vibration force generated is extremely high. After a long time of use, the bolts are easy to loosen, resulting in increased noise from the tuyere during use.
