1、 New spiral extrusion solid-liquid separator

The new spiral extrusion solid-liquid separation unit of Zeyan Zongheng (Shandong) Environmental Technology Co., Ltd. adopts a fast solid-liquid coarse filtration first, and then uses a spiral extrusion working mode for solid-liquid separation. It is an efficient and continuously operated separation and dehydration equipment. The principle of the fast solid-liquid coarse filter is centrifugal separation technology. The main components are: transmission part, machine body, screen mesh and other parts. The principle of solid-liquid separator is spiral extrusion solid-liquid separation technology. The main components include the machine body, screen mesh, extrusion winch, reduction motor, unloading device, and other parts. Widely used in animal manure, slaughter wastewater, distiller's grains, potato residue, wastewater from wood processing enterprises, solid-liquid separation of biogas residue, dehydration of traditional Chinese medicine residue, food industry materials, etc., it is an ideal treatment equipment for solid-liquid separation of blister feces.

This machine has the characteristics of small footprint, simple operation, and convenient maintenance, which makes its feeding more stable. At the same time, it can process liquid materials and high moisture solid materials.
Through our company's multiple technological improvements to the spiral extrusion solid-liquid separator, we have added a convenient flushing design, making it easier for users to maintain and wash the filter screen during use and maintenance. The external body of the machine adopts one-time casting technology and is produced using ductile iron manufacturing process, with a thickened box body. Ensure that users use it year-round. The internal spiral auger is made of stainless steel material, and the stressed parts of the auger blades are treated with manganese for wear resistance The wedge-shaped stainless steel filter screen is also a major innovative technology in the design of this machine by our company. This filter screen has the advantages of good liquid separation effect, not easy to block, and easy to clean. The stainless steel screw, spindle, and filter screen make the machine more widely used, and its corrosion resistance can better meet the needs of acidic and alkaline material treatment.
 
The pig manure, urine, and sewage generated in the pigsty are stored under the pigsty through the leaking floor, using the water soaking manure process. After two weeks or one month of storage, they flow automatically to the collection tank through the siphon pipe under the pigsty. After being roughly filtered by a fast solid-liquid coarse filter, they are separated by a solid-liquid separator. The separated solids can be dried to make organic fertilizer, and the separated liquid is subjected to four levels of precipitation to meet the discharge standards before being returned to the field for irrigation.

2、 Inclined screen solid-liquid separator

The inclined screen solid-liquid separator is an efficient solid-liquid separation equipment widely used in various industrial and environmental fields.

The inclined screen solid-liquid separator is mainly composed of a separation cylinder, a horizontal shaft, a feed inlet, a slag discharge outlet, etc. Its working principle is to use centrifugal force to separate solids from liquids. When the material enters the separation cylinder from the feeding port, centrifugal force causes solid particles to slide along the separation screen and separate, while liquid is discharged towards the tail along the separation cylinder, ultimately achieving solid-liquid separation. In addition, the screen surface design of the inclined screen solid-liquid separator allows liquid to flow out through the pores of the screen surface, while solid matter remains on the screen surface and is separated by gravity.

This device has a wide range of applications in multiple fields, including chemical, environmental, and petroleum industries. In the field of chemical engineering, inclined screen solid-liquid separators can be used for the separation of catalysts, alumina, polymers, etc; In the field of environmental protection, it can be used for wastewater and exhaust gas treatment; In the field of petroleum, it can be used for the treatment of drilling fluids and petroleum wastewater. In addition, it is often used in the treatment of small-scale industrial wastewater such as papermaking, slaughtering, leather, sugar production, brewing, food processing, textiles, printing and dyeing, petrochemicals, etc., to remove solid substances such as suspended solids, floating solids, and sediments.

The advantages of the inclined screen solid-liquid separator include good separation efficiency, large processing capacity, simple operation, and the ability to achieve automated production. Its disadvantage is that the structure is relatively complex, the maintenance cost is high, and due to the fact that the separation screen and separation cylinder are an integral structure, they need to be replaced as a whole when the screen mouth is blocked.
