Quality WSL series shaftless screw conveyor, belt conveyor, conveyor screw conveyor shaft press machine 1, the device name: shaftless screw conveyor 2 main purposes: shaftless screw used in urban sewage treatment plants, housing residential wastewater pretreatment unit, municipal Rain / sewage pumping station and water plant gate slag processing, it is mainly with the grill or dehydration and other equipment for use, the screenings or dewatered sludge transport. 3, specifications: WSL series shaftless screw conveyor 4, knot making and working principle 4.1 shaftless screw conveyor by driving means, shaftless screw, U-shaped groove, liner, cover, expected out other components. Material from the hopper into the spiral, spiral effect in the extrusion, compression, dehydration sent to a cinder notch. Form 4.2 conveyors for shaftless spiral, helical blade thickness of 18mm, spiral blades made of 16 manganese steel material, with sufficient strength and rigidity. Has a replaceable nylon wear collars helical blade between 4.3 and trough, bushing arc radius coincides with the spiral, improve delivery effectiveness and easy maintenance. 4.4 shaftless screw conveyor has sufficient strength and rigidity. 4.5 drive device type parallel shaft-mounted helical gear reducer. Drives overheating, overload protection, can run continuously 24 hours in normal outdoor -40 ℃ ~ 70 ℃ temperature range, and has a protective cover for easy maintenance checks. 5, shaftless screw conveyor features: shaftless screw conveyor screw conveyor shaft compared with the traditions, the use of non-central axis, hanging bearing design, the use of the overall steel auger has a flexible material, the equipment It has the following characteristics. Spiral with superior wear resistance and durability, long service life. Anti-winding strong: no central axis interference, for conveyor-like, easy to wound materials have special advantages, to prevent obstruction caused by an accident. Good environmental performance: a fully enclosed screw conveyor and easy to clean surface, can ensure environmental sanitation and the transportation of materials from pollution, not leaks. Torque, low energy consumption: no axis of the coil, the material clogging, which can lower speeds, smooth transmission, reducing energy consumption. Large transport: transportation volume is 1.5 times the same diameter as the traditional axis of the conveyor of up to 40m3 / h. Long transport distances up to 25 meters, and can be based on user needs, using multi-stage series-mounted, ultra-long-distance transportation of materials. Compact, easy to operate, economic and durable, minimal maintenance, low maintenance costs. 6, the main components Material: Stainless steel plate rack stainless steel spiral groove connected to the powder hopper stainless steel helix on the 16th of manganese steel liner body nylon liner connection accessories, bolts and other fasteners stainless steel electrical control box 7, equipment installation, commissioning and operation (1) Equipment installation requirements: a, feeding and discharging port site installation should be expected out of the flange support surface and screw machine body parallel to the axis; and connecting flange should not have close contact with a gap. b, screw machine installed after the reducer should be checked to add a little oil, then add a little if not increase, the subsequent conduct no-load test; continuously for more than half an hour after making a test run to check the correctness of the screw conveyor assembly, We found the problem should immediately stop processing after the operation until it is in good operating state. c, screw machine operation should be stable and reliable, not loose fasteners. Reducer no oil leakage, no abnormal sound, safe and reliable electrical equipment. (2) Equipment requirements: a, screw machine should start no-load, that is not material in the cabinet at the start, after starting in order to screw conveyor feed. b, initial feed screw machine, you should gradually increase until it reaches the feeding amount conveying capacity, feeding should be uniform, or likely to cause delivery of materials product plug, the drive overload, so that the entire machine is damaged. c, in order to ensure no load starting screw machine requirements, before stopping the conveyor should stop feeding, and other materials inside the casing before stopping completely after delivery finished running. d, the material is transported shall not be mixed within the rigid bulk material, to avoid damage to the death spiral card spiral machine. e, in use, always test the working status of the various parts of the screw conveyor, pay attention to each fastener is loose, loose parts if found, should immediately tighten the screws, so that again strong.
