YDTL70/80/90/100 dewaxing kettle
YDTL70/90 dewaxing kettle is the key equipment for dewaxing of mold shell in investment casting industry. It can also be used as sterilization and disinfection in medicine and food industry. The machine has stable dewaxing speed and easy operation.
First, the main technical parameters:
1, dimensions (mm): 2500 × 1600 × 1950 3200 × 1600 × 1950 3300 × 1700 × 1950
1, the inner diameter dewaxing reactor (mm): φ700 × 1100 φ900 × 1100 φ1000 × 1100
2. Rated working pressure: 1.0Mpa
3, rated working temperature: 183 ° C
4, the degassing kettle rated charging time: <5 seconds
5, weight: 1.7T 2.1T
Second, the structure description:
1. The electrothermal dewaxing kettle adopts an integrated structure, which has a small footprint and simple operation, and effectively increases the temperature of the dewaxing kettle to meet the process requirements;
2. The dewaxing kettle movable door adopts a lock ring structure, which can be quickly opened and closed, safe and reliable;
3. The set wax barrel is made of stainless steel plate, which has no corrosive effect on high quality wax material;
4, with water, wax independent discharge, electric steam generator sewage outlet, etc.;
Third, debugging and operation:
When the electric steam dewaxing kettle water inlet, steam generator drain pipe, drain pipe, dewaxing kettle drain pipe, and wax discharge pipe are connected and installed, and the electric heating pipe and the control box power supply are connected, the debugging can be performed. operating.
1. First check if the pipeline system and circuit system are installed correctly.
2. After carefully checking the system without any abnormality, the battery can be turned on, the power switch is turned on, and the yellow light of the control box is illuminated;
3. Discharge wax, exhaust steam, drainage, sewage, and steam inlet valve;
4. Set the water pump switch to the manual position (should be jog) to see if the pump is rotating forward. If it is forward, open the pump and put the empty cock to discharge the air in the pump and then close the cock (see Spray water can then turn the water pump switch to the automatic position. At this time, the water pump should start working. If it is not working, please find out the reason. When the water level in the steam generator reaches the high water level, the water pump will stop automatically. (Note: the pump is strictly prohibited to idling)
5. Pressure controller adjustment: adjust the adjustment screw of the pressure controller to adjust the required pressure. After the adjustment, the steam generator will automatically stop when it is boosted to the set value, and the difference will be turned to zero.
6. Put the steamed wax tree or recycled material into the dewaxing kettle, close the kettle door, press the handle of the kettle door, pull down the safety buckle, and lock the waxing kettle door;
7. Drainage and wax discharge can be carried out by waxing or draining one or several times according to the wax and water in the dewaxing kettle;
8. When each shift or new kettle starts working, in order to make the wax of the kettle wax ideally dewaxed, it should be preheated, and the above operation is carried out in the empty kettle.
9, the operator should observe the water level to prevent the water level control failure caused by damage to equipment Fourth, equipment maintenance and precautions:
1. The dewaxing kettle is a high temperature pressure vessel, and the operator must be careful to avoid burns;
2. Before the equipment is put into operation, it shall be inspected and registered by the local technical supervision department;
3. The setting of the safety valve must be carried out by the local technical supervision department. No one can damage the seal by himself. To ensure the safety valve is sensitive, the operator should manually open it once a month.
4. When you want to open the door, you should first open the safety buckle, and then open the door after the pressure in the kettle is zero;
5. After the exhaust is completed, the pressure in the kettle is zero, and the wax can be drained and drained at this time;
6. The wax tree enters the kettle and closes the locking kettle door. The shorter the steam inlet time, the better;
7. The filter inside the kettle must be cleaned frequently;
8, when the door since the seal ring is adhered to prevent solidification of the wax tearing seals, cut open the door cold autoclave autoclave autoclave until the wax melts and then open the door;
9. When the kettle door sealing rubber ring leaks, the rubber ring must be replaced immediately;
10. The station is strictly prohibited in front of the gate, and an obvious safety warning device is set up. When the kettle door is opened, the operator should stand on the back side of the kettle door;
11. Before working every day, check the instrument, whether the switch is normal, whether the wax tube is warm, and the wax pump (refer to the case where the wax is discharged into the water evaporation barrel), whether it can be rotated;
12. The water quality of this electric steam generator should meet the requirements of "Industrial Boiler Water Quality". the image is only a reference.
