Description

TECHNICAL FIELD

[0001] The utility model relates to extruder technical field, especially a kind of high-efficiency screw extruder. BACKGROUND

[0002] In the field of environmental governance, especially in the aspect of kitchen waste treatment, the application of screw extruder is particularly important. After coarse crushing and large material sorting, kitchen waste needs to be further treated by screw extruder. In this process, the screw extruder will carry out water distribution, squeezing, pulping and impurity removal processes. These processes are of great significance to improve the treatment efficiency and product quality of kitchen waste.

[0003] Firstly, coarse crushing and large material sorting are the first step of kitchen waste treatment. Through coarse crushing, kitchen waste is broken into smaller particles for subsequent processing. Large material sorting separates large impurities in kitchen waste, reducing the difficulty of subsequent processing. These two steps lay the foundation for efficient operation of screw extruder.

[0004] Next, kitchen waste enters screw extruder for water distribution, squeezing, pulping and impurity removal processes. In this process, the screw extruder will further refine the kitchen waste and add an appropriate amount of water to make the kitchen waste into a pulpy substance. This can improve the treatment efficiency of kitchen waste and also benefit the subsequent impurity removal process. The impurity removal process mainly removes impurities in the pulpy substance to ensure the quality and safety of the final product.

[0005] However, traditional screw extruders have some problems when treating kitchen waste. For example, due to the special nature of kitchen waste, such as high water content and easy spoilage, traditional screw extruders are prone to clogging during use. This not only affects production efficiency, but also may cause damage to the equipment, increasing maintenance costs. In addition, due to the complex composition of kitchen waste, traditional screw extruders are difficult to achieve efficient impurity removal, resulting in unstable final product quality.

[0006] It can be seen that the existing technology needs to be improved and improved. INVENTION CONTENTS
