3results about How to "Improve dust accumulation" patented technology

This utility model relates to the field of lightweight mobile phone frame technology, and discloses a lightweight mobile phone frame including a mobile phone frame. The mobile phone frame has an internal weight-reducing and stabilizing mechanism to reduce the weight of the mobile phone frame. A dustproof mechanism is provided on the front side of the mobile phone frame. Two L-shaped grooves are formed on both the front and rear sides of the inner wall of the mobile phone frame. A spiral hollow channel is formed at the rear end of a trapezoidal guide post 1. A trapezoidal guide post 2 is formed at the rear end of the inner wall of the spiral hollow channel 2. A spiral hollow channel 3 is formed at the rear end of the trapezoidal guide post 1. Reinforcing ribs are fixedly connected to the interiors of multiple spiral hollow channels 1, multiple trapezoidal guide posts 1, and multiple spiral hollow channels 3. In this utility model, the weight-reducing and stabilizing mechanism works in conjunction with the dustproof mechanism, the honeycomb plate is combined with the silicone pillars, and the L-shaped grooves and spiral hollow channels reduce material usage to achieve weight reduction, thus improving the problems of poor weight and drop resistance in existing lightweight mobile phone frames.

This utility model discloses a self-cleaning flame arrester for preventing ash accumulation in a coke oven gas supply pipeline. It includes a coke oven gas supply pipe and two connecting pipes. An automatic ash-cleaning mechanism is welded and fixed at the joint of the two connecting pipes. The automatic ash-cleaning mechanism is inserted into the connecting pipe, which is fixed to the coke oven gas supply pipe by bolts and nuts. A flame arresting mesh is detachably installed on the front side of the automatic ash-cleaning mechanism. The flame arresting mesh has multiple small holes and is fixed to the automatic ash-cleaning mechanism by screws. An ash-collecting mechanism is located below the front side of the flame arresting mesh and is detachably fixed to the connecting pipe by screws. The automatic ash-cleaning mechanism includes a water storage shell and an ultrasonic vibrating rod. The water storage shell is welded and fixed to the connecting pipe and is filled with water. An ultrasonic vibrating rod inserted into the top of the water storage shell is installed therein. Multiple guide rods inserted into the water storage shell are fixed on the flame arresting mesh. This utility model provides convenient flame arrest, has a simple structure, facilitates ash cleaning, and saves manpower.

The application discloses a novel automatic full-dust-cleaning impeller, which comprises a front disc, a middle disc and a plurality of blades which are arranged in a circumferential direction and are arranged between the front disc and the middle disc, a hub assembly is arranged in the middle of the middle disc, a plurality of axial spoiler pipes are arranged in a radial direction on the back of each blade, a plurality of radial nozzles which are used for spraying against the back of the blade are arranged in an axial direction on the side of each axial spoiler pipe which faces the outer periphery of the impeller, a plurality of radial air inlet pipes are arranged on the inner surface of the front disc, each blade corresponds to a radial air inlet pipe, each radial air inlet pipe and the plurality of axial spoiler pipes on the blade corresponding to the radial air inlet pipe are in communication, each radial air inlet pipe has a high-pressure air inlet which extends out of the outer surface of the front disc, a plurality of axial nozzles which are used for spraying against the joint of the axial spoiler pipe and the back of the blade are arranged in a radial direction on each radial air inlet pipe, and high-pressure gas which enters the high-pressure air inlet is sprayed out through the axial nozzles and the radial nozzles.
