Coal washing plant sludge water treatment equipment LW350 horizontal screw centrifugal dewatering machine

Description :

　　Coal washing plant sludge water treatment equipment LW350 horizontal screw centrifugal dewatering machine

　　It is a horizontal spiral discharge and continuous operation settling equipment. The working principle of this type of centrifuge is as follows: the drum and the screw rotate at a certain differential speed and in the same direction at high speed, and the material is continuously introduced into the inner cylinder of the conveying screw through the feeding pipe. After acceleration, it enters the drum, and the material to be separated is subjected to the centrifugal field force; Solid matter with a high specific gravity deposits on the wall of the centrifuge drum, and the screw conveyor continuously pushes the solid matter deposited on the drum, which is discharged from the drum through the drying zone. The lighter liquid is discharged through the overflow weir plate to achieve the goal of solid-liquid separation.

　　The LW350 horizontal screw centrifugal dewatering machine for coal washing plant sludge water treatment equipment is composed of components such as a rotary drum, a screw conveyor, a differential, a main bearing, a chassis, a liquid-solid phase collection chamber, an upper cover, a motor transmission device, and a frequency converter (customized by the user). The working principle of this machine is: the horizontal screw is gradually accelerated by a frequency converter, and under the drive of the main and auxiliary motors, the input shaft of the drum and differential reaches the rated speed n1, n2. Due to the action of the differential, the screw generates a stable differential speed △ n ahead of the drum to achieve the screw discharge function. After the machine speed stabilizes, the suspension enters the centrifuge through the high-level tank or feed pump, flow control valve, and feed pipe, and is accelerated by the screw acceleration bucket before entering the drum. Under the strong centrifugal force field, the solid particles with high specific gravity are thrown onto the settling wall and quickly deposited on the inner wall of the drum. With the push of the screw, the sediment is continuously pushed towards the small end of the drum, and then enters the centrifuge through the slag outlet. Solid phase collection casing is discharged. The separated clear liquid is further clarified by the separation blades and discharged from the overflow hole of the rotary drum and the liquid phase collection cover. Throughout the entire separation process, the suspension is continuously fed in, and the clarified liquid phase and sediment are continuously discharged, hence it is a continuous automatic separation.

　　The advantages of the LW350 horizontal screw centrifugal dewatering machine for sludge water treatment equipment in coal washing plants are as follows:

　　1. Continuous automatic operation

　　The horizontal screw centrifuge adopts automatic control for extracting sludge, injecting liquid medicine, and discharging sludge cake. It is linked with the sludge inlet pump, dosing pump, etc. through an electric control cabinet, and does not require personnel to operate the equipment. The operation will not cause blockage, filter deviation, or other phenomena that affect process safety. Daily maintenance is simple, and it can operate continuously without human intervention for 24 hours. This has truly achieved continuous and fully automatic operation of sludge dewatering.

　　2. Save engineering investment

　　The horizontal spiral centrifuge itself has sludge concentration function, which directly processes aerobic sludge in the aeration tank without the need for concentration and storage units, reducing the overall land occupation and construction cost of sewage treatment facilities.

　　3. Lightweight and durable body

　　The horizontal spiral centrifuge is designed to be quite lightweight due to its direct use of mechanical centrifugal separation and dehydration, without the need for a large body; The body is almost entirely made of carbon steel or stainless steel, with a long service life and durability.

　　4. Equipment is not prone to material blockage

　　The spiral centrifuge adopts a unique large cone angle structure, which makes the equipment less prone to material blockage and eliminates the need for extensive cleaning to prevent filter blockage, reducing the burden of internal circulation and solving the problem of material blockage caused by traditional dehydration equipment for enterprises.
