Qianjin Hydraulic Engineering’s new generation circulating tooth rake mechanical product display
◆Product Overview
Qianjin Hydraulic Engineering’s new generation circulating tooth rake cleaning machine is a device that can continuously and automatically intercept and remove various shapes of debris in the fluid. Special equipment for sewage treatment, can be widely used in urban sewage treatment, tap water industry, power plant water inlet, and can also be used as pre-screening equipment in wastewater treatment processes in textile, food processing, papermaking, leather and other industries. This product is Good treatment results were received during application. It is one of the most advanced solid-liquid screening equipment in my country, filling another gap in domestic sewage treatment machinery and equipment.
◆Working Principle
The new generation of circulating tooth rake cleaning machine is a grille that can be continuously and automatically cleaned. It consists of many identical rake tooth parts assembled in parallel and staggered into a group. The closed rake tooth chain of the circulating tooth rake cleaning machine, driven by the motor and reducer, forms a continuous top-down cyclic movement through a set of sheaves and chains to achieve the purpose of continuously cleaning the grille. When the rake tooth chain moves to the upper part and back of the equipment, due to the guiding role of the sprocket and the curved rail, the parallel rake tooth rows can be misaligned, causing the solid dirt to fall into the slag tank by its own weight and fall off uncleanly. Grilles can easily bring dirt into the channel behind the grille. When the wire rope traction drum mechanical grille is working, the wire rope driving device releases the rope, and the rake bucket descends along the guide rail from the highest position (the end of skimming in the previous cycle), and the skimming plate descends with the rake bucket under the action of its own weight. When the skimming plate is reset, the rake bucket is pushed by the opening and closing rake device (electric push rod) and opened by the traction of the middle steel rope and continues downward until it reaches the lower limit of the channel. After the rake teeth are inserted into the grille gap, the steel rope The driving device retracts the rope, further forces the rake bucket to be completely closed, and then the rake bucket and bucket truck move up along the guide rail, clearing the screen slag until it touches the skimming plate. Under the relative motion of the two, the screen slag is skimmed out and falls through the slag guide plate. The slag tank completes a working cycle.
◆Performance Advantages
The biggest advantages of the new generation of circulating tooth rake cleaning machines are high automation, high separation efficiency and low power consumption.
. Since the rotary chain of the grating machine is equipped with multiple rakes for cleaning, the cleaning efficiency is high and the cleaning is thorough
. It is widely used in food, chemical industry, agriculture, pharmaceuticals, papermaking and other fields. , perform solid-liquid separation and recover useful substances. All achieved good separation and recovery effects.
◆Detailed description of each component of the circulating tooth rake cleaning machine
☆Tooth rake
The tooth rake is composed of many small tooth rakes connected to each other to form a huge rotating surface, which can remove slag thoroughly, cleanly and Flexible and reliable operation. The tooth rake has sufficient strength and rigidity and will not cause bending of the connecting shaft or affect the smooth movement of the rake grid or dechain. The return rake grid after unloading is equipped with a practical and reliable dirt discharge suction nozzle to prevent dirt from adhering to it. The rake teeth are made of stainless steel or nylon.
☆Frame and frame guard
The frame and frame guard of the grille machine are welded with ordinary steel or stainless steel of considerable size to form a rigid support structure. The frame and guard are continuously welded to prevent sewage from leaking out. The inside of the equipment frame is equipped with a traction chain circulating motion rail guide. Both sides of the frame are made of ordinary steel plates or stainless steel plates, which form the frame of the circulating tooth rake cleaning machine. Its cross-sectional size is sufficient to meet the maximum working load interception requirements. The gap between both sides of the rack and the grill well is protected from garbage by rubber sealing plates on both sides of the rack.
☆Rake tooth chain
The rake tooth chain is assembled from a unique set of rake teeth, with strong load-bearing capacity and minimal ring damage. The rake teeth run smoothly, the rake teeth are evenly set, easy to replace and have sufficient strength and rigidity. In order to prevent debris from entering the rake tooth traction chain, a closed traction chain is creatively designed, which makes the equipment run more stable and reliable. The rake tooth ends are rounded, which can effectively remove debris and prevent it from returning to the sewage. The upper part of the equipment is equipped with a cleaning device. This mechanism has flexible movement and adjustable position. It has good cleaning ability. It can clean a small amount of debris adhered to the rake teeth through the reverse rotation of the cleaning brush without clogging. Phenomenon, daily maintenance workload is very small, reducing maintenance costs. Reduce energy consumption.
☆Driving device
The driving device of the circulating tooth rake cleaner has a compact structure and is easy to adjust and maintain. The driving device is equipped with a chain tensioning mechanism and a mechanical overload device, and the safety factor of the chain is greater than. The driving device is flexible, stable and reliable, and has no abnormal noise. The driving device is equipped with a protective cover, and its structure is convenient for maintenance and inspection, and can meet the requirements of outdoor installation. The driving shaft can withstand the load of bending moment and button moment at the same time, and the lubrication of the bearings and all rotating parts of the equipment can be automatically performed. The drive motor is grade insulated, and the rated power of the motor is greater than the maximum actual power consumption of the grille.
☆Measures to prevent chain falling off
The falling off of the traction chain is generally caused by the horizontal movement of the conveyor chain and poor meshing of the sprocket teeth due to the chain being too long. First of all, during the design, the inside of the left and right conveyor chains The pin is designed as a convex shoulder, and one end of the pin is fixed with a circlip. The conveyor chain will inevitably become longer due to working under tension for a long time. It is especially recommended to adjust the tensioner wheel to ensure the normal meshing of the chain drive and ensure the normal operation of the chain drive in the vertical direction.
☆Underwater rotating wheel
The underwater rotating wheel should be in the form of a guide roller, with special reminders to prevent the entanglement of screen debris in the structure.
