Brief description of solid-liquid separation equipment Solid-liquid separation equipment is the whole process of removing total dissolved solids from water or sewage. The removal of solids from sewage is generally carried out by means of sieving or sedimentation. The separation methods used in sludge disposal include sludge force extraction, sludge flotation reagents or sludge dehydration by mechanical equipment.

There are microfiltration, response and deep bed filtration systems in sewage treatment. The process of separating solid and solution is all solid-liquid separation equipment, and there are many methods, such as foundation settlement, filtration, activated carbon filtration, filter press, vacuum pump, centrifugal dehydrator, and pig manure dehydrator uses centripetal force to separate solid fine particles in liquid state. and sediment machinery.

The basic principle of solid-liquid separation equipment From the basic principle, the whole process of solid-liquid separation equipment can be divided into three types of foundation settlement, filtering, centrifugal, and the principles are as follows: The relative density difference between the dispersing chemical substance (solid phase) and the dispersing medium causes it to generate relative velocity and complete the whole process of sludge dewatering.

The filter type uses a certain kind of porous structure chemical substance as a substance. Under the action of external force, the liquid in the mixed liquid is intercepted according to the material pores, and the solid particles are intercepted, thereby completing the whole process of sludge dewatering. The centrifugal type is to use the inertia centrifugal force supplied by the device to complete the whole process of sludge dewatering.

The traditional filter cloth washing method is to remove the filter cloth of the filter press and use a brush after soaking in tap water. This is also a relatively simple, convenient and fast filter cloth washing method. Able to wash off some oil and wax. The oil and wax in the pores of the filter cloth of the filter press are cleaned neatly. The washing method of automatic filter press filter cloth flushing diaphragm filter press is not easy to clean with oil and wax; it is recommended to use traditional washing methods.

The horizontal belt vacuum filter consists of plastic filter belt, vacuum dryer, push roller, horizontal belt support table, feed bin, filter cloth deviation adjustment equipment of filter press, push equipment, filter press filter cloth cleaning equipment, sound card rack and other components. It is an efficient machine and equipment that flexibly utilizes the weight capacity of raw materials and the adsorption force of vacuum pump to complete sludge dewatering. Its principle is as follows:
