The working principle of the Hydraulic desilter

The hydraulic desilter has a mud cyclone desander, which first pumps the mud into a funnel container by a sand pump. The pumping direction is directed along the tangential line to the inner wall of the container. The slurry is rotated by centrifugation, the structure is destroyed, the cuttings and sand are discharged from the funnel, and the mud flows out from the upper opening of the container. The mud cyclone desander has better sand removal effect than the vibrating screen and is widely used in deep well drilling.

The cyclone desander is based on the principle of centrifugal sedimentation and density difference. When the water flows from the sand removal inlet to the equipment in a tangential direction under a certain pressure, a strong rotary motion is generated. Due to the different density of sand and water, the centrifugal force, Under the combined action of centripetal force, buoyancy and fluid drag, the low-density water is lifted and discharged from the water outlet, and the dense sand is discharged from the sewage outlet at the bottom of the equipment to achieve the purpose of sand removal.

Desander process: raw water - swirling sand removal - precision filtration - storage tank - user cyclone desander is based on the principle of centrifugal sedimentation and density difference, when the water flow is under a certain pressure, from the sander inlet to cut After entering the equipment, a strong rotational motion is generated. Due to the different sand water density, the centrifugal force, the centripetal buoyancy, and the fluid drag force are different due to the force, so that the low-density clear water rises and is discharged from the overflow port. The large sand is discharged from the bottom discharge port to achieve the purpose of sand removal. Under certain ranges and conditions, the greater the water inlet pressure of the desander, the higher the sand removal rate, and multiple units can be used in parallel.

When selecting the type of desilter, the desilter should allow a maximum of 1.25 times the maximum displacement of the drilling fluid. The drilling fluid entering the desilter does not have to be treated by a vibrating screen or a desander.

How to desilting municipal drains and canals?

The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device. The trommel screen is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...

The classifications of quartz sand

1. Ordinary quartz sand: The surface of ordinary quartz sand seems to have a layer of yellow skin, and some have large particles and strong fire resistance. It is a kind of quartz sand processed by the manufacturer after using natural quartz ore in the production process, such as washing and drying. No impurities can be seen in the quartz sand through the second water treatment filtration. It is the best choice for chemical water treatment. It can block the sundries suspended in the water and maintain the quality and beauty of the water. 2. Refined quartz sand: Refined quartz sand is a mineral made by the manufacturer after carefully selected quartz stone. According to different requirements of users, the range used is also different. But generally the main use of refined quartz sand is in glass products, because refined quartz sand is refractory and precision casting, especially suitable for fireproof glass materials.
