Fine collection device for screening away gravel in mud

Abstract

The invention belongs to the technical field of screening devices, and particularly relates to a fine collection device for screening away gravel in mud. The fine collection device for screening away the gravel in the mud comprises a machine frame. A head-end roller and a tail-end roller are installed on the machine frame in a rotary mode, a power device is connected to the head-end roller, the portion between the head-end roller and the tail-end roller is surrounded with a conveying net belt, a plurality of driven rollers are arranged between the head-end roller and the tail-end roller and include the upper-layer driven rollers and the lower-layer driven rollers, the center connection line of the upper-layer driven rollers and the center connection line of the lower-layer driven rollers are arranged in a vertically-parallel mode, and the upper-layer driven rollers and the lower-layer driven rollers are arranged at intervals. The fine collection device has the advantages of being simple and compact in structure, safe, reliable, environmentally friendly, light, handy and convenient to install and operate, low in energy consumption, stable in operation, low in vibration noise, high in work efficiency, good in screening effect and adjustable in speed, and saving energy.

Description

technical field [0001] The invention belongs to the technical field of screening equipment, in particular to a sorting device for screening gravel in mud. Background technique [0002] In the oil drilling industry, the general operation process of drilling oil wells involves the operation of pumping the mud from the bottom of the well to the ground and returning it to the bottom of the well for continued use. The main purpose is to separate the broken gravel and After the mud is mixed together, the gravel and mud are backwashed from the bottom of the well to the ground through pump pressure, and the mud filtered out of the gravel is returned to the bottom of the well to continue to press the gravel through the mud pump, and the cycle operation is completed in this way. [0003] The traditionally used device for screening gravel in mud generally uses a vibrating screen as an auxiliary ground device to screen out gravel and filter mud. However, this kind of vibrating screen e...
