Description

Technical Field

[0001] This utility model relates to the field of mineral washing technology, and in particular to a continuous sand and gravel washing device. Background Technology

[0002] After being mined, ores have many impurities on their surface, mostly mud and sand or similar substances. If these surface impurities are not removed during metallurgical processing, it will affect subsequent operations such as crushing, gravity separation, and magnetic separation, which in turn will have a significant impact on the refined products. Therefore, before processing ores, it is necessary to clean off the mud and sand and other impurities on their surface to prevent the muddy materials in the raw materials from clogging the crushing and screening equipment.

[0003] A search revealed an application with application number CN202323493297.3 for a drum-type ore washing machine, belonging to the field of mineral processing technology. Compared with existing technologies, this utility model improves the scouring effect, can discharge wastewater in a timely manner, avoids the re-attachment of sludge, and improves the convenience of feeding and discharging. The overall ore washing process is more efficient and convenient than existing technologies.

[0004] Due to their structural characteristics, existing stone washing machines typically require a large installation space and a long site area, making them unsuitable for factories with limited space.

[0005] To address these shortcomings, we have proposed a continuous sand and gravel washing device. Utility Model Content

After that, the drive motor and the circulating water pump are started. The drive motor drives the second helical gear. With the cooperation of the second helical gear and the first helical gear, the drum screen is driven by the connecting shaft, causing friction between the sand and gravel. The circulating water pump pumps water from the device body to the spray pipe, and the sand and gravel are washed by the spray head. The guide hopper is set to guide the sand and gravel, guiding the sand and gravel being washed in the upper drum screen to the lower drum screen for continuous washing.

[0015] 2. In this utility model, after the sand and gravel are washed, the impurities will fall onto the filter plate. Then, the vibration motor is started to drive the filter plate to vibrate, causing the impurities to pass through the filter holes on the filter plate.

With the cooperation of the second helical gear 5 and the first helical gear 4, and through the action of the connecting shaft 3, the drum screen 2 is driven, causing friction between the sand and gravel. The circulating water pump 9 pumps water from the device body 1 to the spray pipe 10, and washes the sand and gravel through the spray head 11. The guide bin 8 is used to guide the sand and gravel into the upper drum screen 2. The sand and gravel being rubbed are guided into the lower drum screen 2 for continuous rubbing. This utility model has a simple structure and is easy to operate. It adopts a double-layer sand and gravel rubbing structure, which greatly reduces the space occupied by the device without affecting the rubbing effect, and is suitable for more scenarios. After the sand and gravel are rubbed, the impurities will fall onto the filter plate 13. Then, the vibration motor 16 is started to drive the filter plate 13 to vibrate, which causes the impurities to pass through the filter holes on the filter plate 13.
