XYQG series of sludge cutting machine is the Nanjing German environmental protection equipment manufacturing limited company according to the sludge dehydration process in the presence of large solid particles, strong adhesion of the objects into the pipeline, produce viscous drag phenomenon such as machine, equipment research and development, is a horizontal spiral centrifuge products.
Structure characteristics
Main parts: shell, motor bearing, main shaft, cutting knife and speed reducer.
Material: carbon steel, stainless steel
XYQG type sludge cutting machine for sealing operation. The inlet and outlet water, water inlet, equipped with adjustable valve, adjusting the feed concentration can be viewed from the observation window, can be modified according to the concentration of water for cutting and crushing and washing, the sludge solids concentration reach to the ideal state.
main features
1, unique dual shaft design, independent cutting blade and gasket installed in the two parallel rotation axis, alternating overlap, spiral cutting, cutting effect is excellent. The blade and the gasket are made of alloy steel, which is uniform, high strength and high efficiency.
2, blade unique design, can crush rigid and flexible material. The motor is driven by a motor speed reducer to rotate, and the strong squeezing force and the shear force are generated. Low speed operation torque is big, the effect is good.
3, mechanical seal and framework oil seal assembly, no need to seal flush, adjust, easy to use and maintenance.
4, different amount of water, pipe type crusher head loss is small, circulation efficiency is good, the water flow is smooth.
5, when a blockage occurs, the control cabinet will issue instructions to the mill, the blade automatically reverses, the obstacle to withdraw from the re grinding, to achieve intelligent management, to meet the requirements of unattended.
6, the use of different gear configuration modular design, to meet the special requirements of users.
Application occasions
1, pipeline crusher is suitable for the vast majority of in-line equipment or pipeline applications, without the transformation of the pipeline or channel system;
2, installed in the pump station, sewage treatment plant imports;
3, this machine can crush the items are: paper products, wood products, plastic products, rubber products, domestic waste, etc..

4 product features
4.1 in the water to be broken, can not only protect the water treatment equipment, but also can avoid the leakage of odor, protect the environment.
4.2 broken performance is excellent, with overload protection function, safe and reliable operation, can be automatic control. If the crusher in the broken sewage solid waste generated overload, it will produce overload current, the electric control system will automatically action, break the opportunity to immediately reverse the moment, solid waste discharge, return to normal work.
4.3 installation and maintenance is simple.
5 structure and working process
PG crusher is mainly composed of vertical crusher, pipe connection, electric control box and so on. Vertical crusher mainly consists of driving parts, driving shaft, driven shaft, milling cutter, mechanical seal, shell and so on. The drive unit drives the driving shaft to rotate and drive shaft by crushing machine, precision gear drives the driven shaft to rotate, which are fixed on the cutter shafts are reverse rotation, and the solid crushing bite.
5.1 structural characteristics:
5.1.1 crusher reducer and motor shaft mounted bevel gear reducer, making the crusher structure is compact, installation and maintenance is more convenient.
5.1.2 vertical crusher drive shaft and driven shaft speed varies, so that the clearance between the milling cutter.
The milling cutter used in the 5.1.3 vertical crusher is in the left and right spiral, and is arranged on the left and the right spiral after the driving shaft and the driven shaft are arranged in order to reduce the crushing force and improve the transmission stability of the crusher.
5.1.4 vertical crusher bearing part of the mechanical seal, to protect the normal operation of the vertical crusher bearing.
5.2 separate cutting blades and gaskets
5.2.1 cutting blades and gaskets with high strength alloy steel, the surface is polished evenly and hardened to the minimum 45-50HRC.
5.2.2 cutting blades, gaskets and horizontal clearance between the shaft is not more than 0.65mm, to ensure the normal drive of the cutting blade, reduce wear and increase the pressure of the gasket.
To ensure the 5.2.3 particle size, blade tip height should not exceed 13 mm root diameter.
5.3 axis
The drive shaft of the crusher and the drive shaft are made of high strength alloy steel, Quenched and tempered, meet the strength requirements.
5.4. base and casing
Crusher base made of nodular cast iron, a guiding device, it entered the pulverizing screen at the same time under the guidance of solid particles, can play a protective role of bush. The upper shell is ductile iron.
5.5 reducer
Reducer performance is good, to adapt to the harsh environment, with a larger damping capacity.
5.6 motor
Using IP54 motor, the motor in the air can be used normally. Motor rated power is 220/380, V/3 ph/50 Hz 2.2KW, the motor service coefficient is 1.15, at full load, the efficiency factor is not less than 85%, the power factor is not less than 80%.
6 main material
Heat treated alloy steel for cutting blade
Gasket heat treated alloy steel
Shaft 2 Cr13, stainless steel
Base carbon steel
Shell grey cast iron
Fasteners stainless steel
7 electrical control
Seven.1 usually for manual control, can also be automatically controlled or according to the customer need to set aside PLC interface. The controller is equipped with open shut / reset - automatic gear selector switch: "in the" off / reset "file, the crusher operation should be stopped; in the" open "file, crusher operation; in the" automatic "file, crusher on / off, by the remote controller to control the open or stop. Only to switch to "off / re set" file, the crusher will be re set.
7.2 safety measures
7.2.1 blocking occurs when the controller in the open / automatic two modes will stop the crusher, and make it to reverse to clear obstacles. After the blockage is cleared, the controller will return to normal operation. If the blockage is still present, the controller automatically executes the reverse process in 30 seconds, up to three times. If the three time reversal after congestion still exists, the motor power controller will be broken, and the startup delay and abnormal status indicator.
7.2.2 if the crusher works normally, when the power is restored, the crusher will resume normal operation.
7.2.3 if broken off normal stop operation, a sudden power failure, when the power is restored, the abnormal state indicator will start automatically.
By installing 7.2.4 in the broken machine overload protection relay starter, controller for motor overload protection.
7.2.5 short circuit protection is done by the addition of an appropriate size circuit breaker or fuse.
The reset of the 7.2.6 controller is controlled by the local switch panel.
8 performance test
8.1 the protective cover and driving mechanism and the whole machinery in the factory assembly and test run, verification machinery in accordance with the requirements of the design requirements and the relevant standards.
8.2 before delivery, the quality, specifications, performance, quantity and other comprehensive inspection of the goods.
8.3 field performance test project
8.3.1 to detect the appearance size, appearance quality.
8.3.2 noise check: run, the noise value is not greater than 76dB (A).
8.3.3 electrical control cable wiring is correct, neat, no safety factor etc..
8.3.4 mechanical overload protection device is sensitive and reliable, and the alarm signal is sent out when the overload is over.
8.3.5 test run precision. The whole test run should be smooth, continuous operation for 48 hours. When the equipment works, the operation is steady, no jam, scratching and abnormal phenomenon, flexible and reliable action mechanism.
