3results about How to "Increase sieving rate" patented technology

This utility model relates to the technical field of powder vibrating sieving, and more particularly to a multi-stage powder vibrating sieving device. The utility model provides a multi-stage powder vibrating sieving device, including a dustproof shell, a feed plate, a discharge plate, a guide plate, a vibrating motor, and connecting blocks. The feed plate is slidably fitted onto the top of the dustproof shell, and a feed inlet is opened on the top of the feed plate. The discharge plate is fixedly connected to the front side of the dustproof shell, and the guide plate is fixedly connected to the bottom of the dustproof shell. Two vibrating motors are fixedly connected to the bottom of the guide plate. Four connecting blocks are fixedly connected in a rectangular array at the lower part of the dustproof shell. This utility model, by setting a multi-layer screen structure, can sieve materials into three different particle size grades in one go, meeting various particle size requirements. Under the linear reciprocating vibration generated by the vibrating motor, the material jumps along the screen surface, fully contacting the screen surface and improving sieving efficiency.

This invention relates to the field of screening equipment technology, specifically a vibrating screen for hot-drilling equipment with negative pressure dust collection. It includes a support frame, to which circumferentially distributed first elastic elements are fixedly connected. These first elastic elements are collectively fixed to a screening cylinder. A screen cylinder cover is fixedly connected to the support frame. The screening cylinder is fixedly connected to a first screen, a second screen, and a bottom baffle. Both the first and second screens have an array of circumferentially distributed screen holes. A third screen is rotatably connected to the screening cylinder. An air supply module is installed on the support frame. This invention uses the screening cylinder, second screen, third screen, and bottom baffle to form a sealed cavity. The air supply module continuously supplies air into the sealed cavity, increasing the pressure within the cavity. When the screen holes on the second and third screens connect, the lower airflow impacts the blocking particles upwards, achieving the purpose of clearing the blockage caused by hot-drilling particles.

This invention relates to the field of underground coal and gangue sorting technology, and in particular to an underground coal and gangue multi-layer feeding and screening device based on layered vibration adaptive technology. The device includes a multi-layer screening assembly, a drive assembly, and a control assembly. The multi-layer screening assembly is fixedly mounted on a frame and includes screening modules arranged longitudinally on the frame. Each screening module operates independently, and the screening particle size of the modules decreases progressively from top to bottom. The drive assembly is fixedly mounted on the frame and is connected to the screening modules via a transmission connection, providing screening power to the modules. The control assembly includes an electrically connected control module and a detection module. The control module is electrically connected to the drive assembly, and the detection module is used to detect the screening parameters of the coal and gangue. This application achieves efficient and stable screening under complex working conditions by decomposing thick material layers through multi-layer feeding, differentially configuring the vibration parameters of each layer, and introducing a real-time sensing and feedback adjustment mechanism, thereby promoting the clean utilization of coal.
