Roller type macadam screening jet flow ore washing equipment

Abstract

The invention discloses a jet ore washing equipment for drum-type crushed stone screening, which comprises a water storage tank, an ore washing shell, an ore washing net cylinder, a spiral blade, a high-pressure jet hole and a hollow rotating shaft. The bottom of the ore washing shell is welded There is a water storage tank, the bottom of the water storage tank is welded on the support frame, the inner bottom of the water storage tank is set as a water storage tank, and the filter residue net is installed on both sides above the water storage tank, and the upper end of the filter residue net is connected to the separator, and the two ends of the separator are equipped with Slag drop hole; the ore washing shell is equipped with an ore washing net cylinder, and the ore washing net cylinder is respectively connected to the feeding cover and the discharge cover through the rotating guide sleeve, so that the hollow rotating shaft and the ore washing net cylinder can be driven to rotate at the same time. The hollow rotating shaft is opposite to the rotation direction of the ore washing net cylinder and is combined with the flushing of the high-pressure jet hole, which has a good cleaning efficiency and effect on the ore; after cleaning, the water flows into the water storage tank to realize water recycling; the ore washing net cylinder effectively filters out the ore The slag in the filter can improve the screening effect of the crushed stone.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a jet ore washing equipment for drum-type gravel screening. Background technique [0002] In the process of ore mining, it is often necessary to clean the mined ore in order to remove a large amount of dirt and other impurities contained in the ore, and also remove a large amount of slag mixed in the ore; The trough type ore washing machine is composed of a transmission device, a screw shaft, a trough body, and a lifting frame. It has strong cutting and scrubbing capabilities, and has a strong ability to break up small mud lumps. It is suitable for processing medium-sized muddy particles. Lots of hard-to-wash ores. But this trough washing machine has the following problems: 1. The working principle of the transmission device is that the motor drives the small spur gear on the reducer, the small spur gear drives the large spur gear on the intermediate shaft, and the smal...

Problems solved by technology

But this trough washing machine has the following problems: 1. The working principle of the transmission device is that the motor drives the small spur gear on the reducer, the small spur gear drives the large spur gear on the intermediate shaft, and the small bevel gear on the intermediate shaft Drive the large bevel gears on the left and right helical shafts to rotate

The assembly of the small bevel gear and the large bevel gear with this structure is difficult, the vibration and impact of the equipment is large, and the start is not stable; 2. The lower end shafts of the left and right screw shafts are in the tank and sink in the slurry, and the slurry is easy to enter the bearing seat and wear the bushing. Short bushing life
