There are various sections and machines of a complete automatic concrete slats production
line. The machinery and equipment of each slat manufacturing process can be divided into the following sections:
1. Raw material processing section
First of all, raw material batching: the main aggregates such as stone and stone chips are accurately proportioned by PLD batching machine. Cement, fly ash and other powder materials are mainly accurately proportioned by FL powder metering device. Water is to be proportioned by separate SL water metering. In this process, the raw material proportioning is carried out at the same time without interfering with each other. Requirements for the ambient temperature in the rated working conditions should be 5 ~ 30 ºC.
Secondly, the above raw materials which are proportionally completed according to the process requirements are put into JS series mixer for forced mixing in turn. Once again, the evenly mixed raw materials will be transported to the mobile receiving hopper through the conveyor belt. The mobile receiving hopper, according to each production line needs materials, will be transported and unloaded to the fabric system in the main machine of the manure leakage board. Finally, the fabricator spreads the raw aggregate evenly into the corresponding moulds.
Reinforcing steel configuration for independent operation steps, first of all, the steel straightening, cutting, rust removal. Then through the automatic welding machine, it will be welded into the required specifications of the mesh, and finally it will be welded into the frame which is called the grid. Before the raw material fabrication machine spreads the raw material to the corresponding mould, the mesh is placed into the mould by hand. The mixer, hopper and fabric machine must be cleaned once every shift, and only after the cleaning is completed can they be handed over to the next shift for use.
2.Leakage slab blanks forming section
The production of leaky slab brick blank forming process is the key, first of all, the mould vibration, the mould is grid and cloth aggregate, mould below the vibration forming platform vibration vibrator start produced eccentric amplitude, vibration time is generally in 1-2min. at the same time in order to keep the surface smooth after molding need to use the automatic wiping unit for grinding plane processing, wiping time is very short, normal in 50-80s, wiping is completed and then need to continue to After the smoothing is completed, it is necessary to continue to vibrate the slurry surface, the slurry surface should be smooth and even. With the vibration stops, can be through the manure leakage board host flip demoulding. The moulded blanks are put off smoothly onto the pre-positioned pallet. Normal tray has four layers, the first layer for the cart tray, the remaining three layers for the bracket tray. The trays are placed on fixed repair racks, and only one piece of tray can be placed at a time. After demoulding is completed, the pallets with blanks are stacked on the hook-push rails in sequence by means of plywood stacking on the plywood truss machine.
3.Pre-raising finished product section
The pre-culture room is located at about 10 metres off the middle of the leaking slab line and has a length of 22 metres. The main mechanism is the push trolley, whose function is to push the stacked billets to the pre-nursing room in order. Of course, a film is attached to the blanks before they enter the chamber for better preconditioning. The stacked blanks are stored in the room for 6-12 hours to complete the final setting of the concrete, at this time the blanks have been cured and called the first finished product can be palletised. The turning truss machine takes over the sequential linkage control and can turn over and palletise each stacked primary product. After palletising, the pallets are stacked by forklift trucks and placed on the site for natural conservation, and become finished products after 7-21 days of conservation. The empty pallets after palletising are recovered by the plywood truss machine and recycled in the billet forming section.
