Mineral processing wastewater treatment equipment

1、 Introduction to Mineral Processing Wastewater Treatment Equipment:

It can continuously concentrate and filter a large amount of sludge. The product is made of high-strength materials and has significant characteristics such as high processing capacity, high dewatering efficiency, and long service life. It is widely used in sludge concentration and dewatering treatment in various industrial and municipal industries. The bearings it is equipped with have a long service life, and high-quality filter belts are usedSUSThe nozzle fully ensures the performance and quality of the filter press.

2、 Working principle of mineral processing wastewater treatment equipment:

After the concentrated sludge is fully mixed with a certain concentration of flocculant in a static and dynamic mixer, the small solid particles in the sludge aggregate into larger flocculent clumps, and free water is separated. The flocculated sludge is transported to a filter belt for concentration gravity dewatering, where free water is separated under the action of gravity to form a non flowing sludge. It is then sandwiched between two mesh belts and gradually squeezed through a wedge-shaped pre pressure zone, a low-pressure zone, and a high-pressure zone under the action of small to large extrusion pressure and shear force, to achieve a large degree of separation between sludge and water, and then discharged as a filter cake.

3、 Characteristics of beneficiation wastewater treatment equipment:

1The retention time of sludge concentration is short,The retention time of traditional sludge concentration tanks generally takes more than ten hours,The average dehydration residence time in the belt concentration section is only a few tens of seconds1- 2minute.

2The belt type concentration section is designed to be inclined,Added static pressure head for the feed section,Improve dehydration efficiency.

3Both the concentration section and the pressure filtration section adopt stepless speed regulation,To achieve ideal process matching.

4Filter cloth correction device:Adopting pneumatic feedback for single-sided automatic correction.

5Filter cloth cleaning device:Using efficient nozzles and washing mechanisms for automatic cleaning.

6Filter cloth tensioning device:Adopting pneumatic tensioning,Therefore, the operation is flexible,Easy and convenient maintenance.

The filtrate of the wastewater treatment equipment in the beneficiation plant flows into the filter bag through the side inlet pipe of the filter housing. The liquid can permeate through the filter bag of the required fineness level to obtain qualified filtrate. Similarly, impurities such as particles will be intercepted by the filter bag. This filter is not only very convenient to replace the filter bag, but also has no other material consumption, which is energy-saving and environmentally friendly.

4、 Troubleshooting of Mineral Processing Wastewater Treatment Equipment:

1.Belt slippage

The reason is that the tension of the conveyor belt is low or there is material or moisture stuck on the surface of the driving drum. The tension screw should be tightened to increase the tension. Clean the drive drum and increase the cleaning force of the empty section cleaner.

2.The conveyor belt deviates at both ends

The reason is that the assembly position of the drum is skewed, and the screw of the tensioning device on the deviated side should be tightened and adjusted to the position of the drum. Adjust the position of the transmission drum by adjusting the bearing seat.

3.The conveyor belt deviates in the middle

The reason is that the installation position of the roller is not correct. Check whether the installation position of each roller is perpendicular to the conveyor belt, otherwise loosen the installation bolts and adjust the roller position. After adjustment, tighten all bolts.

5、 Precautions for Mineral Processing Wastewater Treatment Equipment:

1. Check if all fasteners are loose.

2.When the rubber scraper of each cleaner and guide groove wears out, its extended size should be adjusted. If the wear is severe, replacement should be carried out.

3.When multiple conveyors or other equipment are used in conjunction, attention should be paid to the starting and stopping sequence: empty load starting should be maintained; After the feeding port equipment stops supplying materials, this equipment should be operated for a period of time to unload the empty materials before stopping.

4.After parking, clean up the dirt on the conveyor and turn off the power.

5.If the device has been out of use for a long time, it should be checked whether there are any foreign objects on the device that affect the movement of moving parts before starting.

6、 Scope of application:

1Suitable for dewatering water sludge;

2Can be used for dehydration in industrial sectors such as starch and juice processing;

3Suitable for dewatering metallurgical sludge from blast furnaces, converters, sintering, and other sources;

4Suitable for dewatering sludge generated from wastewater in papermaking, leather, animal husbandry, aquaculture, chemistry, food and other industries.

7、 Startup steps:

1Add flocculant and start the liquid mixing system.

2Start the air compressor, open the intake valve, and adjust the intake pressure to the specified levelMpsprice

3Start the cleaning water pump, open the inlet valve, and start cleaning the filter belt

4Start the main drive motor to ensure the normal operation of the filter belt

5Start the flocculant dosing pump, sludge feeding, and flocculation mixing motor in sequence

6Adjust the intake pressure to0.6MpaApply pressure to both filter belts

7Adjust the amount of sludge and the speed of the filter belt to achieve better processing capacity and dehydration rate

With the technological improvement of belt filter press, we have achieved great success in sewage treatment by utilizing it. moreMineral processing wastewater treatment equipmentSustainable Focus Company Website (www.sdmzjscl. com)!
