进口卧螺离心机Product Description:

The screw conveyor is located inside the drum shell, the feed pipe is connected with the inner pipe of the screw conveyor, the inner pipe is provided with a discharge port, the outer circumference of the inner pipe is fixed with spiral blades, the light phase outlet is located on the end cover on the side of the drum shell, the isolation disk of the disc system is set between the spiral blades at the end of the screw conveyor and the light phase outlet, the isolation disk is fixed with the screw conveyor, and the isolation disk is provided with a flow channel near the inner pipe, A solid phase channel is provided between the isolation disk and the inner wall of the drum; The disc system is located between the isolation disk and the light phase outlet, and the disc system is fixed to the drum. By adding a disc system between the drum shell and the inner tube near the light phase outlet, the minute solid particles are quickly separated from the liquid phase, which greatly reduces the content of the minute solid particles in the liquid. Therefore, the final clear liquid with higher purity can be obtained. The filtration treatment of the minute solid particles is unnecessary in the subsequent process, and the centrifugal capacity of the centrifuge is increased.

进口卧螺离心机characteristic:

Horizontal screw centrifuge is a kind of high-efficiency centrifugal equipment used for solid-liquid separation, which can be used in the centrifugal treatment process of sludge produced in the process of industrial and civil sewage treatment. Compared with belt filter press, horizontal screw centrifuge is widely used in the industrial field because of its inherent characteristics of large processing capacity, automatic operation and good dehydration effect. Fig. 1 and Fig. 2 show the structure of the existing horizontal screw centrifuge. The drum includes a conical small end and a cylindrical large end. The small end and the large end are fixedly connected with the small end cover and the large end cover respectively. The feed pipe passes through the small end cover and communicates with the hollow inner pipe of the screw conveyor. The outer circumference of the inner pipe is fixed with spiral blades. The inner pipe close to the feed pipe is provided with a discharge port, and several spiral blades far from the feed pipe are provided with separation channels, The lower part of the small end of the drum shell is provided with a slag phase outlet, and the large end cover is provided with a light phase outlet. The large end cover is fixedly connected with the drum shell. The drum and the screw conveyor are controlled by the differential speed. During operation, the suspension to be separated is continuously transported to the hollow inner tube of the screw conveyor through the feed pipe, and enters between the high-speed rotating drum shell and the inner tube through the discharge port of the screw conveyor. Under the action of centrifugal force, the solid particles rapidly settle on the inner wall of the drum, the drum and the screw conveyor rotate in the same direction at a differential speed, and the screw conveyor pushes the solid particle sediment to the drying area at the small end of the drum, After the two-way extrusion by the thrust of the screw conveyor and the centrifugal force of the sediment, the sediment is further squeezed and dehydrated, and then discharged from the slag phase outlet at the small end of the rotary drum. The separated clear liquid moves to the light phase outlet through the separation channel, and finally discharged from the light phase outlet. In actual work, the existing horizontal screw separators have poor treatment effect when processing materials containing small solid particles. Small solid particles are difficult to be separated and will be discharged together with the light phase, resulting in high solid content of the light phase. In the subsequent processing process, more precise centrifuges must be set to centrifuge the light liquid again.

进口卧螺离心机Principle:

A horizontal screw centrifuge, a screw conveyor is located inside a drum shell, a feed pipe is connected with the inner pipe of the screw conveyor, a discharge port is set on the inner pipe, a spiral blade is fixed on the outer circumference of the inner pipe, a light phase outlet is located on the end cover on the side of the drum shell, an isolation disk of a disc system is set between the spiral blade at the end of the screw conveyor and the light phase outlet, and the isolation disk is fixed with the screw conveyor, A flow channel is opened at the side of the isolation disk close to the inner pipe, and a solid phase channel is provided between the isolation disk and the inner wall of the drum; The disc system is located between the isolation disk and the light phase outlet, and the disc system is fixed to the drum. By adding a disc system between the drum shell and the inner tube near the light phase outlet, the disc system rotates with the drum except for the isolation disk, and the isolation disk rotates with the screw conveyor. Under the action of the huge centrifugal force field, the initial clear liquid entering the disc system will quickly separate from the liquid phase, settle on the inner wall of the drum of the horizontal screw centrifuge, and then discharge the drum through the screw conveyor, The disc group can reduce the settling distance and increase the settling area, and at the same time, it can improve the settling speed, so that small solid particles can be separated quickly. After separation by the disc system, the content of micro solid particles in the liquid is greatly reduced, so the final clear liquid with higher purity can be obtained, and the filtration treatment of micro solid particles is not required in the subsequent process. By integrating the existing horizontal screw centrifuge and disc system, the beneficial effect of simplifying the two processes of large particle solid and small particle solid separation into one process is realized. It has the advantages of increasing the centrifugal capacity of the centrifuge, reducing the space occupied by multiple processing machines, low cost, and saving production and operation costs.
