Hydrocyclone prevents clogging

The use of cyclones is relatively common. It is a relatively common device that combines centrifugal force and gravity. Because the operation of the cyclone device is relatively simple in structure design, it has been used in many industries. When the cyclone device is used, there will definitely be problems. A brief introduction, everyone should read it carefully.
Friends who have used hydrocyclones may know that when the equipment is working, there are many factors that cause the cyclone in the water to block, such as the ore that is spilled on the outside and bricks and tiles, etc., may be careless Dropping into the cyclone causes clogging of the device. If you encounter this problem when using a hydrocyclone, you must solve it in time. If it is not found, it will cause the slurry to overflow and increase its concentration. This phenomenon is relatively common when using a hydrocyclone. I hope you will pay attention to observe the running status of the equipment during the operation to avoid this situation.
1. Avoid cyclone blockage. You can work from the installation of the screen. We can install the screen according to the actual situation on the spot. Of course, regular cleaning work must also be done.
Second, if we are using a pump pool with a height difference, a roller screen can be installed before it. The advantage of this is that it saves labor and will not block the hydrocyclone.
3. If conditions permit, choose a large-diameter hydrocyclone as much as possible, so that the sand sink of the equipment will increase correspondingly and there will be no blockage.
4. If the operator finds a blockage when using the cyclone, at this time, in order not to delay normal work, the previously prepared spare cyclone can be opened to clean the blocked equipment. After the sink of the hydrocyclone is blocked, if the cyclone is not resolved in time, the cyclone drama will produce violent vibration. The basic screw is likely to be broken, so if we find a problem, we must solve it in time to avoid unnecessary trouble
The above is the cause and solution of the blockage of the hydrocyclone. Everyone must pay attention to the operation status of the equipment when using the equipment.
Check method of whether the hydrocyclone is blocked:
1. If neither the overflow pipe nor the underflow pipe of the hydrocyclone has slurry flowing out, the feed pipe is completely blocked.
2. If only a small amount of slurry flows out of the overflow tube of the hydrocyclone, or no slurry flows out of the overflow tube, and the underflow flows out in a straight line, the feed tube is partially blocked.
3. If there is no slurry flowing out of the underflow of the hydrocyclone and the flow rate of the overflow pipe is normal, the nozzle is blocked.
4. If the overflow of the hydrocyclone is small, and the underflow is large, and the underflow is ejected from the middle to the surroundings, the overflow pipe is partially blocked.
Hydrocyclone is suitable for processing fine materials, the particle size is about 0.25-0.01mm. Generally, when the feed pipe of the hydrocyclone has debris or scars, it will block and the classification will not proceed properly. If the feed tube of the hydrocyclone is only partially blocked, then the feed cannot directly flow out of the hydrocyclone nozzle, and the classification cannot be performed. If the overflow pipe of the hydrocyclone is partially blocked, then the normal swirl flow will not be formed in the hydrocyclone, most of the slurry will be ejected from the nozzle, and the effect of classification will be reduced.
