Embodiment 1
[0052] (1) As shown in the figure, the screw extrusion solid-liquid separation equipment of this embodiment includes a screw extrusion cavity, a first fixed end, a discharge hopper, an auger, a second fixed end, a filter screen, an extrusion unit, Adjustment unit. Wherein, the screw extrusion cavity is tubular with two ends open, the first fixed end is connected with one end opening of the screw extrusion cavity, and the discharge hopper is arranged on the other end opening of the screw extrusion cavity. The screw auger includes a variable-pitch helical section and a smooth section connected with the variable-pitch helical section as a whole, and the variable-pitch helical section is located between the first fixed end and the discharge hopper. In this embodiment, the variable-pitch helical section adopts an equal-diameter variable-pitch design, and the design of the variable-pitch helical section is shown below. At the same time, the second fixed end is connected with the sc...

The present application discloses a screw extrusion solid-liquid separation device, which aims to solve the problems of low extrusion efficiency and high energy consumption in the existing screw extrusion dry-wet separation equipment. Different from the existing screw extrusion equipment, the applicant has optimized and improved the structure of the extrusion equipment based on the separation of the defect causes of the existing screw extrusion solid-liquid separation equipment, so as to improve the efficiency of the extrusion equipment and reduce its energy consumption . In this application, the helical auger with variable-lead helical features is used, and the adjustment device that can adjust the compression amount of the spring is used to realize accurate adjustment of the extrusion pressure. Based on the improvement of the structure, the structure of the present application is simpler, and the service life of the auger is significantly improved, and based on the mutual cooperation of the auger and the pressure regulating device, the extrusion part of the screw extrusion solid-liquid separation equipment The force distribution is more reasonable, which can effectively improve the extrusion efficiency, prolong the service life of the equipment, effectively reduce energy consumption and equipment maintenance costs, and have high application value.
Description
technical field [0001] The present application relates to the field of solid-liquid separation, in particular to the field of solid-liquid separation by screw extrusion, and specifically to a solid-liquid separation device for screw extrusion. More specifically, the application provides a dry-wet separation device for livestock and poultry manure, which has the advantages of simple structure and high extrusion efficiency, can meet the needs of livestock and poultry manure separation, and has extremely high application value. Background technique [0002] In recent years, with the continuous development of agricultural technology, especially the rapid development of animal husbandry, the pollution of livestock and poultry manure to the environment has become more and more serious, so people have paid more and more attention to it. Livestock and poultry manure is rich in nutrients and trace elements. It is a good organic fertilizer and feeding raw material. Recycling it as a r...
