Tower type sand making unit

Abstract

The invention relates to a tower type sand making unit. The tower type sand making unit comprises a multi-layer vertically-arranged steel structure supporting frame body and a PLC control system; a movable feeding mechanism is arranged outside the steel structure supporting frame body; a crushing and screening mechanism and a dust collecting mechanism are arranged in the steel structure supportingframe body; the movable feeding mechanism comprises an elevator and a Y-shaped discharging articulated chute; double rails are arranged at the bottom of the steel structure supporting frame body; theelevator is arranged on the outer rail of the double rails; the Y-shaped discharging articulated chute is arranged above the crushing and screening mechanism; the dust collecting mechanism is arranged on one side of the crushing and screening mechanism; the crushing and screening mechanism and the movable feeding mechanism realize a cycle; the crushing and screening mechanism comprises a crusher,a screening machine and a movable material receiving bin; the movable material receiving bin is arranged on the inner rails of the double rails and comprises a coarse crushing product bin and a finecrushing product bin; a vertical main pipe of the Y-shaped discharging articulated chute is connected with the crusher; and a first branch pipe and a second branch pipe are both connected with the elevator. The tower type sand making unit is provided with sandstone feeding, crushing, screening and shaping mechanisms, so that the requirement that sandstones with different particle sizes are discharged at the same time is met.

Description

technical field [0001] The invention relates to the technical field of sand crushing, in particular to a building-type sand making unit. Background technique [0002] At present, in the production of sand and gravel, the layout of the traditional sand making production line includes plane layout and building station layout. Among them, the plane layout has the advantages of large floor area, difficult dust removal and environmental protection, poor environmental protection effect, and requires several dust collectors. The system collects dust in different areas, and the investment in environmental protection is large. The floor-to-floor production system has a compact structure, a small footprint, and saves space. [0003] However, the existing building-type sand and gravel preparation system has a single equipment configuration, and mostly uses a single crushing main machine-made sand, which has the following defects: (1) The requirement for the particle size of the feed i...

Problems solved by technology

[0003] However, the existing building-type sand and gravel preparation system has a single equipment configuration, and mostly uses a single crushing main machine-made sand, which has the following defects: (1) The requirement for the particle size of the feed is high. If the quality of the finished product is to be improved, both sand making and shaping must be considered. As a result, the speed and frequency of the main engine cannot be increased, resulting in low output and high energy consumption; (2) The product is single, because the feed size is too small, only sand can be produced, which cannot meet the demand for sand and gravel output at the same time. For a system that only produces finished sand Generally speaking, the coarse aggregate whose particle size does not meet the requirements of the finished sand must be returned to the sand making machine for secondary crushing to meet the requirements of the finished sand. The production is not flexible and cannot meet the needs of customers. If customers need rice stones and crushed stones, it is bound to be Increase equipment investment
