What should be paid attention to in the installation density of hydrocyclones? Recently, many friends have such questions. The cyclone manufacturer will focus on explaining it today, hoping to help everyone.
If the water level of the mixing barrel or mixing barrel is low, adjust the barrel position; if the pressure is unstable, check whether the valve of the air pipe is tightened and closed; the cyclone developed by this technology can be used without changing the inside of the cyclone The strong swirling field guides the separation of heavy and light media under the condition of free rotation, reducing the probability of separated heavy media returning to light media and guiding the enrichment of heavy media;
Stop the operation of the machine immediately and replace the gasket. If the faults are handled incorrectly, it will not only reduce the service life of the machine, but also may cause safety hazards and cause accidents. The cyclone is a widely used separation and classification equipment based on the principle of centrifugal sedimentation. When the two-phase mixture to be separated enters the cyclone tangentially from the periphery of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotating shear turbulence will be generated.
The underflow concentration of the cyclone is generally planned to be around 50%. Such parameters are conducive to the secondary dehydration work of the vacuum belt dehydrator and also help maintain the quality. If the underflow concentration of the cyclone cannot reach the planned level, how to deal with it, let's talk about the underflow concentration adjustment method of the cyclone.
Various failures are inevitable when the cyclone is in use, but how to deal with the failure is really important. The underflow concentration of the cyclone does not reach the level required by the plan. There are several reasons for the composition of this problem. To determine the root cause of the problem, it is necessary to understand and analyze the three parameters of the cyclone, that is, the progress of the cyclone. Material density, underflow density and overflow density.
As one of the important industrial separation and classification equipment, hydrocyclone has been widely used in chemical, petroleum, metallurgy, papermaking, mining, food, medicine, environmental protection, building materials and coal industries. In the field of mineral processing, hydrocyclones exist in almost every ore dressing plant and are widely used in operations such as classification, sorting, concentration, and desliming.
At the same time, the underflow port is at the bottom of the spiral groove and the complete cone-bottom design can avoid the "air column" that is not conducive to separation in the traditional cyclone, which can greatly improve the separation performance of the traditional cyclone, thereby improving the separation efficiency of heavy media And reduce its division diameter, reduce the phenomenon that is not conducive to separation. There is too much light material in the underflow of the leakage material of the cyclone body.
If there are coal lumps in the mixing tank, clean it up in time; below, our company will introduce to you the specific faults and treatment measures of the heavy medium cyclone. A type of spiral groove type cyclone with external protrusion. This technology has outstanding technical advantages. Existing cyclones are all partially improved built-in cyclones, and their internal components have greater interference and destructiveness to the free rotating flow field, the overflow phenomenon is relatively serious, and the separation efficiency improvement space is limited.
Due to the difference in particle size between coarse particles and fine particles, the size of the particles subjected to centrifugal force, centripetal buoyancy, fluid drag, etc. is different, so most of the coarse particles are discharged through the underflow port of the cyclone, while most of the fine particles are discharged by the overflow The pipe is discharged to achieve the purpose of separation and classification. The technology has obvious market advantages and industrialization value at the same time.
The above is what Chaishang Trading Co., Ltd. introduces you to pay attention to the installation density of hydrocyclones. For other questions about hydrocyclones, please refer to other content on this site or call for detailed inquiries.
