Introduction to the performance of the reverse grate decontamination machine
This machine is generally used as a coarse grate and is suitable for removing larger suspended solids and floating solids in sewage in various municipal and industrial sewage treatment plants. The grate is placed at the rear of the main frame, and several decontamination rakes are connected with the material chain and rotate in the frame. When the decontamination rakes pass through the grate, they rake out the dirt in the water intercepted by the grate and send it to When it reaches the top of the machine frame, it will be discharged from the slag discharge port by the slag discharge device. This machine is suitable for use in wider and wider grid trenches. It runs smoothly, has high efficiency, is easy to use and maintain, and is equipped with an overload protection device.
Application occasions of the type reverse grate decontamination machine
Generally used as a medium or coarse grate, it is a substitute for the rotary grate. The shallow channel type reversing grille decontamination machine can be designed to rotate around a fulcrum on the water and out of the water according to the user's maintenance needs to facilitate maintenance. The anti-scoop grate decontamination machine can also be used in large-scale water conservancy projects to achieve the purpose of collecting and removing slag.
Characteristics of the reverse grille decontamination machine
In the pre-sewage treatment process, it intercepts and removes various solid particles, floating objects, etc. So that the subsequent processing procedures can be carried out smoothly. It is a key equipment for blocking and removing slag during the treatment of municipal sewage, industrial sewage, textile and papermaking. This machine has grid gears, chain plates, etc. to form a grid to replace the traditional grid bars. The grid rotates in the frame, thereby intercepting and continuously separating suspended solids in the sewage. Therefore, the work efficiency is high, the movement is smooth, the water level difference between the front and rear of the grid is small, and there is no blockage.

Installation and debugging of the reverse grille decontamination machine Preparation before installation
First organize the installation personnel to familiarize themselves with the structure, function and characteristics in the installation diagram, and understand the relevant knowledge of the equipment . A dedicated person should be responsible for unpacking the equipment. After unpacking, check whether the equipment parts are complete and damaged according to the packing list. Inspect, clean and oil if necessary, then put them neatly and cover them with oilcloth or plastic sheeting. The construction foundation drawings and installation drawings should be used to check the foundation elevation and the location and dimensions of foundation embedded parts, and their errors should be within the allowable range. During installation, hoist the complete machine into the channel and place it in the correct position to ensure the level of the main shaft, the equal clearance between the frame and both sides of the channel, and the reliable sealing of the water seal rubber plate. You can use expansion bolts to fix it to the foundation or weld the frame pad. On the foundation embedded steel plate (depending on the foundation conditions).
Precautions for the initial operation of the reverse grille decontamination machine
The equipment should be comprehensively inspected and oiled before the machine. Check that each fastener must not be loose. Adjust the tightness of the transmission chain and rake traction chain. Check the oil level of the reduction box. If there is no oil or insufficient, add lubricating oil. For details on the collective filling method and oil brand, please refer to the "Reducer Instruction Manual". Start the motor and check whether the rake is running in the correct direction. The tooth rake runs upwards in front of the grid (inlet water surface). After confirming that there are no abnormal phenomena, officially start the motor. If there is no abnormality after running for several hours, water can be put into the test run. Operation and Maintenance During operation, if there are fiber debris and other debris blocking the rake tooth chain, they should be cleaned in time. So as not to affect the normal operation of the equipment. If the motor runs normally but the rake tooth chain does not drive during operation, it means that the safety pin is cut off due to overload, and the overload safety pin must be replaced. Add the same lubricating grease (calcium-based grease) to the rolling bearing once a week, and inject it into the grease nozzle with a grease gun. Regarding the maintenance and inspection of the reducer, please follow the "Reducer Instruction Manual".
Storage and maintenance of the retractable grille decontamination machine
After the retractable grate decontamination machine is produced from the factory, the storage conditions are dry transportation and storage. The relevant provisions for storage are as follows: Storage and storage: Check the delivered machine for transportation damage, and check the integrity of each accessory according to the delivery record. The grille decontamination machine must be placed flat in a clean, dry, and vibration-free room. For long-term storage, the machine must be protected from heat and moisture. 1. To protect all shiny parts from moisture, anti-rust measures must be taken. If necessary, they must be sealed and packaged with dry materials to achieve moisture-proof effect. Their protective capabilities must be checked every season. The quality guarantee is that the product will not be used for more than three months provided that the user abides by the requirements and conditions for storage and use. If the product is damaged or fails to work properly due to poor manufacturing, our factory will repair or replace parts for the user free of charge. This does not apply to easy damage and wear.
Instructions for use of the electric control box
The voltage is constant, the grounding resistance is less than ohms, and the grounding should be safe and reliable
Open the door of the electric control box and close the circuit breaker
As needed Control by pressing the button on the door
It is best to turn off the circuit breaker and lock the door during use
Maintenance of the electric control box
Check the electric control box regularly to see if there is an electric shock After loosening, dust should be removed. If water accidentally enters, stop using it. You can dry or air-dry the electrical control box and manage it well. It should not be opened or damaged by outsiders and should be cared for and maintained by a professional electrician.
