When quartz sand filter material is prepared by wet method with water washed over the surface, it shall be dried and treated: firstly, quartz sand filter material is sent to the hopper by belt conveyor or bucket elevator, and then enters the feeding end through the feeding pipe by the feeding machine of the hopper.The slope of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow into the dryer smoothly.The dryer cylinder is a rotating cylinder that is slightly tilted from the horizontal line.The material is added from the higher end, and the heat carrier enters from the lower end, and contacts with the material in reverse flow. Some heat carrier flows into the cylinder together with the material.With the rotation of the cylinder, the material moves to the lower end under the action of gravity.In the process of moving forward in the cylinder body, the wet material is directly or indirectly heated by the heat carrier, which makes the wet material dry and then sent out by the belt conveyor or the screw conveyor at the discharging end.In the cylinder body wall is equipped with a copy board, its role is to copy up and spread the material, so that the material and the airflow contact surface increase, in order to improve the drying rate and promote the material forward.Heat carrier is generally divided into hot air, flue gas and so on.After the heat carrier passes through the dryer, it is usually necessary for the cyclone dust collector to collect the materials in the gas.If it is necessary to further reduce the dust content of tail gas, it shall be discharged again after passing through a bag-type dust remover or a wet dust remover.
The dryer barrel produced by Weifang Guote company is made of 304 stainless steel with high purity and no pollution.Internal material lifting device, so that the material dispersed evenly, conducive to evaporation of moisture, external insulation.Heat source can be biomass raw materials or natural gas, high thermal efficiency, environmental protection and no pollution.The whole equipment is simple and reasonable in structure, easy in operation, low in failure rate and easy in maintenance.The whole production line is equipped with high temperature resistant environmental dust collector, the whole production process without dust, pollutant emissions.Welcome customers to visit the purchase.
