The inclined installation of the hydrocyclone is more suitable for providing constant underflow with variable circulating load, which can reduce the wear of the sand setter, but it performs poorly on the high concentration loop. The diameter productivity and overflow particle size of the cyclone increase with the increase of its diameter. Generally, the large diameter cyclone has poor efficiency and the overflow contains more coarse particles.
What you need to know about the use of polyurethane cyclones!
The size and shape of the mine opening is increased, the processing capacity increases, the overflow particle size becomes coarser, and the classification efficiency decreases. The gypsum hydrocyclone mainly separates the mixed liquid through the rotating grille, rotating drum and overflow nozzle. From the perspective of the structure of the dynamic cyclone separator, it does not have the chaotic tangential inlet like the static cyclone separator, the cyclone chamber with cylindrical section, the larger conical section and the long exhaust pipe.
If the number of blade-type rotating grid blades is too small, the flow field in the drum will be unevenly distributed; if the number of blades is too large, the flow area of ??the liquid flow will decrease, and the pressure loss and shear fracture of the droplets will increase energy level. Unfortunately, he went forward without obedience. The overflow of the gypsum hydrocyclone is located at the end of the cyclone separator.
Configure a rotating grid that can pre-accelerate the liquid entering the drum as required. Today, there are mainly two types of blade type and spiral type. The taper should be planned at the end of the blade-type rotating grid to allow a rotating liquid to overflow the inner cavity of the rotating drum, so as to stabilize the flow transition and avoid strong vortex.
The dynamic hydrocyclone is the main separation area along the length of the drum. The main structural elements that affect its separation function are the structure and size of the rotating grille, rotating drum, overflow nozzle and oil collecting sleeve. The design of the hydrocyclone is also affected by the ball mill used in closed-circuit grinding. For example, the feed rate of the ball mill and rod mill is constant, the circulating load is constant, and the slurry supply of the cyclone is also constant. The self-mill is the opposite. And the circulating load is variable, so the slurry feed is also variable.
Cylinder height The size of the column height affects the length of time the slurry is subjected to centrifugal force. Generally, the column height is 0.6 to 1.0 times the diameter, which is straight. The rotating raft is located at the inlet end of the cyclone separator drum. If the friction force between the inner wall of the drum and the liquid flow causes the liquid to rotate at a high speed, the resulting vortex force may be unsatisfactory. In order to obtain sufficient tangential velocity rod solution.
Polyurethane cyclone design variables The cyclone design variables generally include the diameter of the cyclone, the inlet diameter, the diameter of the overflow, and the height of the overflow. The gypsum hydrocyclone drum is the main occasion for liquid mixing. The dynamic hydrocyclone processing capacity separator is the friction force generated by the rotating drum at high speed, which is used to tune the pre-accelerated flow of the rotating grid to form the required centrifugal force.
The main function of is to collect the unseparated light phase (such as kerosene) and squeeze it by the rod. Water sounded from the circumference of the rod. The cavity is crowded. In order to obtain a better expected separation result, the structure of the overflow nozzle is designed as a tapered surface. This gypsum hydrocyclone structure can reduce the diameter of the inlet and reduce the flow rate, and guide the stable flow of the liquid flow, avoiding the formation of violent vortexes and destroying the volatility of the flow field.
The main structural elements that affect the static cyclone separation function are the shape and number of tangential inlets, the main diameter and length of the cyclone chamber, the structure and size of the size cone, and the main resolution of the main diameter of the cyclone chamber. The size of the large cone section is mainly used for pre-acceleration of eddy currents. The small cone section mainly plays a role of separation. The tail pipe is mainly undulated by the core and has no single function.
The drum is a high-speed moving part. Parts, disassembly deviations and even material defects may lead to unbalanced centrifugal force during rotation: The diameter and insertion depth of the overflow tube of the hydrocyclone increase the size of the overflow tube, the processing capacity increases, the overflow particle size becomes coarser, and the classification efficiency decreases. The diameter of the grit nozzle is large, the overflow flow is small, and the overflow particle size becomes finer. The grit nozzle is small, the grit concentration is high, the overflow flow is large, and the coarse particle content is high.
