PG type sludge cutting machine (pipe crusher) Technical performance description
1. Application PG type mud cutter (pipe crusher) is a new type of sewage treatment equipment developed for the treatment of solid substances mixed in pipelines. The machine can transport solids such as cloth, wood chips and empty bottles and cans, which are mixed in the pipeline, to the smasher in the mud cutter (pipe crusher), and the water can flow through to prevent the clogging of pipelines and processing equipment and ensure the pipeline. The processing equipment is operating normally. The equipment can be used in conjunction with conventional pumping stations, or it can be used on its own, which is mainly suitable for sewage treatment plants and transit pumping stations.
The items that can be broken by this machine are: rags, glass, paper products, wood products, physiological products, empty cans, dregs, rubber products, ropes, hoses, leather products, and plastic products.

4. Features
4.1 The crushing treatment in water can not only protect the water treatment equipment, but also avoid the leakage of odor and protect the environment.
4.2 Excellent crushing performance, overload protection, safe and reliable operation, automatic control. If the crusher generates an overload when crushing the solids in the sewage, an overload current will be generated and the electronic control system will automatically act. The crusher will instantly reverse and discharge solids and return to normal operation.
4.3 Simple installation and maintenance.

5. Structure and working process PG crusher is mainly composed of vertical crusher, pipeline connection, electric control box and so on. The vertical crusher is mainly composed of a drive component, a drive shaft, a driven shaft, a milling cutter, a mechanical seal, a housing, and the like. The driving part of the crusher drives the drive shaft to rotate, and at the same time, the drive shaft drives the driven shaft to rotate through the precision gear, so that the milling cutter fixed on the two shafts rotates in reverse, and the solid object bites and crushes.
5.1 Structural Features:
5.1.1 Crusher Reducer and motor adopt shaft-mounted bevel gear helical gear reducer, which makes the crusher compact and easy to install and maintain.
5.1.2 The speeds of the active and driven shafts of the vertical crusher are different, so that self-cleaning of the slag between the milling cutters can be achieved.
5.1.3 The milling cutter used in the vertical crusher is left spiral and right spiral, and is arranged in the left spiral and right spiral after being loaded into the driving shaft and the driven shaft to reduce the crushing force and improve the smoothness of the crusher. .
5.1.4 The vertical crusher bearing part uses a mechanical seal to protect the vertical crusher bearings from working properly.
5.2 Independent Cutting Blades and Gaskets
5.2.1 High-strength alloy steel for cutting blades and shims. The surface is ground uniformly and hardened to a minimum of 45-50HRC.
5.2.2 The horizontal clearance between the cutting blade, spacer and shaft should not exceed 0.65mm to ensure that the cutting blade can normally drive, reduce wear, and increase the pressure of the gasket.
5.2.3 To ensure particle size, blade tip height should not exceed 13 mm of tooth root diameter.
5.3 Shaft crusher drive shaft and driven shaft made of high-strength alloy steel, quenched and tempered to meet the strength requirements.
5.4. Base and Casing The base of the crusher is cast from nodular cast iron and has a deflector device that acts as a protective bushing while directing the solid particles directly into the crushed grid. The upper casing is ductile iron.
5.5 Reducer The reducer performs well, adapts to harsh environments, and has a large shock absorption capability.
5.6 Motor With IP54 motor, the motor in air can be used normally. The rated power of the motor is 2.2 KW, 220/380 V/3 ph/50 Hz, and the motor service factor is 1.15. At full load, the efficiency factor is not less than 85% and the power factor is not less than 80%.

7. Electric control
7.1 It is usually manual control. It can also be automatically controlled or PLC interface reserved according to customer needs. The controller is equipped with “open-close/reset-automatic” third gear selection switch: in the “close/reset” file, the crusher should stop running; in the “open” file, the crusher operates; in the “automatic” file, The on/off of the crusher is controlled by the remote controller to start or stop. The crusher will only be reset if the switch selection is reached in the “Off/Reset” file.
7.2 Security Measures
7.2.1 When a jam occurs, the controller will stop the crusher in both open and automatic modes and reverse it to remove obstacles. After the jam is cleared, the controller will resume normal operation. If the jam condition still exists, the controller automatically performs the reversal process within 30 seconds and can execute up to three times. If the jam is still present after three reversals, the controller will cut off the power to the motor and initiate the delay and abnormal status indicators.
7.2.2 If the crusher operates normally and suddenly loses power, the crusher will resume normal operation when the power is restored.
7.2.3 If the crusher stops operating abnormally and suddenly loses power, the abnormal state indicator will start automatically when the power is restored.
7.2.4 The controller provides motor overload protection through an overload protection relay installed on the crusher starter.
7.2.5 Short circuit protection is done by installing an appropriately sized circuit breaker or fuse.
7.2.6 The reset of the controller is controlled by the local switch panel.
8. Performance test
8.1 The protective cover and drive mechanism and the entire machine are assembled and tested at the factory to verify that the machine meets the performance requirements and related standards specified in the design.
8.2 Before shipment, conduct a comprehensive inspection of the quality, specifications, performance, quantity, etc. of the goods.
8.3 Field Performance Test Items
8.3.1 Check the external dimensions and appearance quality.
8.3.2 Noise check: In operation, the noise value is not greater than 76db(A).
8.3.3 The electrical control should be properly wired, neat cables, and safety factors.
8.3.4 The mechanical overload protection device is sensitive and reliable. When overload occurs, an alarm signal is issued and the equipment stops working.
8.3.5 Test running accuracy. The test run of the whole machine should be steady and run continuously for 48 hours. When the equipment is working, the whole machine runs smoothly without any jamming, scratching or abnormal phenomena, and the mechanism is flexible and reliable.
