Central transmission thickener installation operation manual

Central transmission thickener is mainly used for clarifying and concentrating coal slurry or ore pulp in mines, achieving the purpose of dehydration.

Central transmission thickener can also be used in power, chemical and other departments to process other types of slurry

1.Installation and commissioning

1. The manufacturer ships the components to the user, so before installation, all components should be counted according to the random shipping list. If there is any loss or damage, it must be supplemented or repaired.

2. Install the baseboards at both ends of the bridge and the columns of the concentration tank, embed the corner bolts, pour cement, and ensure that the four baseboards are on the same horizontal plane. It is best to use a theodolite for calibration. After the cement to be poured solidifies, the host can be installed.

3. Tighten the segmented bridge frames together with bolts and weld reinforcement plates.

4. Lift the bridge onto the column of the concentration tank and align the centerline of the main shaft of the transmission device with the center of the concentration tank.

5. The hanging angle steel on the stabilizing cylinder is connected to the bridge frame with bolts. Before welding the stabilizing cylinder and the hanging angle steel, the upper end surface of the fixed cylinder should be adjusted to be 170mm higher than the overflow weir surface of the concentration tank, while ensuring that the cylinder is in a vertical position.

6. Connect the disassembled driving rake device with bolts to form a whole.

7. Install the rake frame, use bolts to install the four rake frames on the side of the square table at the lower end of the drive device, and then weld the four rake frames together with a pull plate and rod.

8. Install the rake teeth, requiring the bottom edge of the rake teeth to be 80-100mm away from the bottom of the concentration tank, and all rake teeth to cover the entire bottom area of the tank. The rake teeth at the end should be about 100-150mm away from the inner wall of the concentration tank.

9. Assemble the feeding tube, make holes on the outer circumference of the stabilizing cylinder, and then weld it.

10. After all mechanical parts are installed, calibrate the verticality of the transmission shaft. If it is not vertical, it will affect the overall operational performance of the machine. Place the level on the oil cylinder support at the top of the transmission device for calibration. An adjustment pad can be added to the foot of the gearbox of the transmission device for adjustment. When the level is in a horizontal position, the transmission shaft is also in a vertical position.

11. Weld both ends of the bridge frame to the baseboard.

12. Install the hydraulic station oil pipe, and ensure reliable connections at all joints without any oil leakage.

13. Connect the electrical part to the power cord.

14. After all assemblies are completed, conduct a test drive. Before the test drive, add oil to the hydraulic motor reducer, gearbox, and hydraulic station oil tank until the oil level is at the marked position. For the debugging process during the test drive, please refer to the hydraulic system debugging instructions later. The test run time for air transportation should not be less than 2 hours. At this time, it is necessary to observe whether the rake rotation direction is correct (counterclockwise), whether the operation is smooth, and whether there is no abnormal noise, whether there is oil leakage in the hydraulic pipeline, and other abnormal phenomena. Then conduct a rake lifting test to observe whether the rake lifting and lowering are normal, and whether the travel switch works when the rake lifting reaches the limit position. If there are any abnormal phenomena, the fault must be eliminated. The requirements for water test and load test are the same as those for air transfer test, and the load test time shall not be less than 24 hours.

2. Lubrication of the machine

1. N220 industrial gear oil (approximately 60Kg) is used for hydraulic motor reducers.

2. Use N460 industrial gear oil (approximately 120Kg) in the gearbox.

3. In the hydraulic station, N46 anti-wear hydraulic oil is used in summer, and N32 anti-wear hydraulic oil (approximately 220kg) is used in winter.

4. After the first refueling run for a week, replace the oil with a new one. From then on, replace it every six months and refuel regularly.

5. Lift the shaft section and add lubricating grease (ZGN-2) once a week.

6. After each shift starts up, use an oil gun to spray thin oil on the spindle and guide keys for lubrication once.

3. Operating procedures and maintenance

1. The feeding can only be done after each shift is turned on and running normally.

2. The tools, equipment, and other items carried by maintenance personnel must not fall into the pool.

3. Regularly check whether the oil pipe leaks, whether the oil circuit is unobstructed, and whether the circuit joints and contacts are in good condition.

4. Regularly add oil to each lubrication point.

5. Regularly keep the machine clean.
