In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.
Referring to fig. 1 and 2, the invention discloses an energy-saving and environment-friendly deironite powder recycling and granulating process, which comprises the following steps:
(1) and collecting: absorbing the stone powder mixed with the scrap iron generated by cutting and polishing the stone through a dust collector;
when the stone powder passes through the dust hood 1, the magnet 10 arranged in the dust hood magnetically attracts the iron filings;
b, washing the stone powder without the iron filings to the conveyer belt 2 by using water;
(2) mixing materials: respectively adding stone powder and natural biogel into a spiral conveyor 3 for conveying, stirring into a mixture and extruding;
(3) and drying: drying the mixture of stone powder and natural biogum extruded from the spiral conveyor 3 by a drying device 4;
(4) and granulating: and conveying the dried mixture into a granulator 5, granulating the dried mixture by using the granulator, and packaging and storing.
According to the energy-saving environment-friendly deironing powder recycling and granulating processing technology, a dust collector is used for sucking stone powder into a collecting cover 1 in the stone cutting and polishing process, iron in the stone powder is adsorbed by a magnet 10 on the collecting cover 1, the deironing stone powder is continuously sucked into a pipeline of the dust collector, the scrap iron-removed stone powder is washed onto a conveying belt 2 by water, and the collected stone powder is granulated and processed into particles for storage; the scrap iron is uniformly collected on the collecting cover, so that not only can iron be recycled, but also the effect of recycling the iron-removing stone powder is good, and the iron-removing stone powder is more energy-saving and environment-friendly; the invention not only can solve the problem of land occupation of the stone powder, but also can avoid the flying of the dust in the cutting and polishing process by recycling, improve the working environment and be beneficial to protecting the body health of workers; the environment pollution is avoided, and the environment is more protected; and natural biological glue is adopted to mix stone powder, so that the stone powder is more environment-friendly.
The invention also comprises a dehydration step between the step (1) and the step (2), stone powder and water are conveyed to a screw conveyor 3 through a conveying belt 2, and excessive water is filtered during the conveying process.
The invention collects the water filtered out in the dehydration step and circularly uses the water to wash stone powder generated by cutting and polishing the stone material to enter a stone powder collecting tank; the filtered water contains a small amount of stone powder, and the environment is polluted by the small amount of stone powder when the water is directly drained, so that the water is used for washing the stone powder again, the drainage problem is solved, the water resource is recycled, and the water is saved.
According to the dust collector, the air delivery pipe 11 is arranged above the conveying belt 2, the air delivery pipe 11 is provided with the plurality of spraying ports 12, the stone powder after iron removal is conveyed into the air delivery pipe 11, water flow sprays and washes the stone powder in the air delivery pipe 11 to the conveying belt 2 through the spraying ports 12, and the conveying belt 2 filters redundant moisture in the stone powder in the process of conveying the stone powder to the screw conveyor 3.
The natural biological glue is prepared by mixing crushed algae and water and stirring; the algae is used for secreting mucus or producing colloidal substances, so that the stone powder can be firmly bonded together; and the algae is used for preparing the natural biological glue, so the cost is lower.
In the invention, before the step (2), algae and water are stirred in advance by a stirring mechanism 6, wherein the mixing weight ratio of the algae to the water is 10: 3-5; the viscosity of the uniformly mixed natural biological glue is better.
