ZPD Vacuum Harrow Dryer
First, the guide area, wet sludge into this area and high temperature hot air contact with the rapid evaporation of water, the material in the big corner of the copy board copy, the shape will not be bonded into the next work area;
Second, the discharge area, drums in this area does not copy board, material rolling in this area to the discharge port to complete the entire drying process;
Third, the clean-up area, wet sludge in this area was copied from the form of copy the formation of material curtain state, the material is easy to form when the phenomenon of adhesive drum wall, in this area because the device design has a cleaning device, cleaning device will be very reasonable cleaning The adhesion of the material within the wall, in this process, the cleaning device for the material ball agglomeration also from the crushing effect, thereby increasing the heat exchange area, improve the drying rate;
Fourth, the tilt plate area, wet sludge in this area has been a low moisture loose state, the material in this area has no bonding phenomenon, after the heat exchange of materials to meet the required water state, into the final discharge area There are a variety of microbial rivers and tunnels have been neglected by people, but also for urban environmental management to bring many problems. I plant research and development of sludge drying equipment can be sludge drying, to facilitate the production of sludge bio-organic fertilizer, organic fertilizer manufacturing enterprises preferred drying equipment.
Sludge special dryer is an indirect heating low-speed mixing dryer. There are two or four hollow shafts inside the equipment. The hollow shafts are arranged in parallel with the hollow wedge-shaped hollow blades. The structural design is particularly clever. The relative rotation of the shaft body, the use of the same angular velocity and linear velocity of the different principles and structure cleverly reached the shaft on the sludge self-cleaning effect, to maximize the sludge drying process to prevent the "axis" phenomenon. With the fastest speed makes the sludge in the process of drying quickly crossed the "adhesive phase area." While the ingenious structure makes the sludge in the process of drying to achieve a two-way shear state. The dried sludge is fed into the feed port of the dryer continuously by the screw feeder, and the sludge enters the body, and the sludge is turned over by the rotation of the blade to stir and stir, and the heating interface is continuously updated to contact the body and the blade , Is fully heated, so that the surface of the sludge contained in the water evaporation. At the same time, the sludge with the blade shaft rotation into the spiral trajectory to the direction of the delivery side of the delivery, continue to stir in the transport, so that the sludge in the water to continue to evaporate. Finally, the dry uniform product is discharged from the discharge port. The use of jacketed shell structure, making the sludge in the machine within the various interfaces even heat, shaft rotation, the sludge is not in the equipment within the somersault, heating surface constantly renovated. Thus greatly improving the efficiency of the equipment steaming, both to achieve the purpose of sludge drying, but also to achieve a complete set of low-cost operation of the device.
It is an innovation horizontal batch-type vacuum dryer. The moister of wet material will be evaporated by heat transmission. The stirrer with squeegee will remove material on hot surface and move in the container to form cycle flow. The evaporated moisture will be pumped by vacuum pump.
The following raw materials from pharmaceutical industry, foodstuff industry, chemical industry and so on can be dried.
Suitable for pulpiness, paste-like mixture or powder raw material.
Thermal sensitive raw material having the requirement to dry at lower temperature.
Raw materials that are easy to oxidize or explode and have strong irritative or toxic.
Raw materials that need to recover solvent.
