Shaftless screw conveyor

 Shaftless screw conveyor

Supporting and control system of centrifuge - shaftless screw conveyor

Shaftless screw conveyor Product model: WLS

No axis Screw conveyor It is used to transport materials through a powerful rotating steel screw, which can effectively transport dry, wet, viscous, powdery and rough materials. The design of shaftless screw can effectively prevent the influence of blocking and winding, so that the conveyor can easily transport different materials.


Application range of shaftless screw conveyor:

WLS type shaftless screw conveyor is mainly suitable for conveying grid slag Sludge dewatering machine Mud cake, etc. Structure and working principle: Type A shaftless screw conveyor is composed of driving device, shaftless spiral, U-shaped groove, lining plate, cover plate, feed hopper, discharge port, etc. Its working principle is: materials enter the conveyor from the feed hopper and are pushed to the discharge port by the rotating shaftless screw.


Performance characteristics of shaftless screw conveyor:

1. Simple structure, no bearing in the conveying trough, smooth material conveying;

2. The whole conveying process is carried out in a closed conveying trough, so that the materials will not overflow and secondary pollution will be avoided;

3. Shaftless spirochetes are integrally formed by special processing technology, with a one-time forming length of more than 2.5 meters;

4. Low speed operation, low noise, low energy consumption, maintenance free..


Installation form of shaftless screw conveyor:

The standard type is ground fixed horizontal installation type or inclined installation type, and can also provide hanging type, ground and hanging mixed fixed inclined type, mobile type (can rotate around the axis of the feed inlet) and other special installation methods according to the user's requirements.

 Longyou biogas slurry and residue treatment

Longyou biogas slurry and residue treatment

The equipment of this project is applied to the separation of pig and cow dung, biogas slurry and biogas residue. The enterprise has introduced three LW-450 centrifuges from our company, and the actual processing capacity of a single machine is 15-18m ³/ h。 The moisture content of the material after treatment is less than 75%, and the separated material is in the form of dry wood chips, which can be blown away by the wind. The customer was extremely satisfied with this. The introduction of this equipment has solved the problem of excessive residue of biogas slurry after the customer used the extrusion solid-liquid separator. The high solid content of biogas slurry directly affects the anaerobic fermentation effect. The use of horizontal spiral centrifuge

 Construction pile driving mud treatment

Construction pile driving mud treatment

In building construction, piling is one of the common procedures to ensure the stability and safety of buildings. However, the mud waste generated during pile driving needs to be effectively treated to protect the environment and ensure the cleanness of the construction site. Pile driving mud treatment technology came into being and became an important aspect of the construction industry. Pile driving mud is composed of water, soil or sand, which contains a lot of suspended solids, particles and chemicals. If not treated, the mud will pollute the surrounding environment, even
