However, its transmission efficiency is relatively low, and because kitchen waste is a liquid-solid mixture, it is corrosive to treatment equipment, and its composition is very complex, and its corrosion form is relatively special
If corrosion-resistant alloys such as stainless steel or titanium alloys are used as core components, the cost will be very high. If low-cost materials such as cast iron are used, the corrosion resistance will not be sufficient. If organic synthetic materials are used, the strength will not meet the requirements.

Embodiment 1
[0024] A kitchen waste screw rod composite conveying device includes a casing, a screw rod, a motor, and a transverse rotating wheel arranged at an upstream part of materials in a form orthogonal to the screw rod.
[0025] The screw rod includes a shaft of the shaft and fins spirally surrounding the shaft of the shaft, and the included angle between the slope of the fins and the axis of the shaft of the shaft is 132 degrees.
[0026] The horizontally rotating wheel includes a rotating wheel body and blades arranged on it. The blades are plate-shaped, in a plane with the axis of the rotating wheel body, and form an angle of 90 degrees with the surface of the rotating wheel body.
[0027] The material of the rod shaft is corrosion-resistant cast iron, and its chemical composition is calculated by weight percentage: C: 3.5%, Si: 1.8%, Mn: 1.3%, Cr: 0.3%, Ni: 1.9%, Mo: 0.25%, Cu: 0.13%, RE: 0.05%, P: 0.09%, S: 0.05%, and the balance is Fe and unavoidable impurities.

Abstract
The invention relates to a screw rod composite conveying device for kitchen garbage, and belongs to the field of environmental protection, in particular to the field of kitchen garbage disposal; the integral structure of the screw rod conveying device serving as a link among various devices in a kitchen garbage disposalsystem is improved, and simultaneously, the material of the screw rod conveying device is correspondingly improved, leading to great improvement of the efficiency of the conveying devices, and meanwhile, improvement of the durability; as a result, more comprehensive running of the whole kitchen garbage disposalsystem can be guaranteed.
Description
technical field [0001] The invention belongs to the field of environmental protection, in particular to the field of kitchen waste treatment, and in particular relates to a kitchen waste screw compound conveying device. Background technique [0002] The existing kitchen waste treatment generally adopts landfill, but landfill not only wastes land, but also causes secondary pollution of groundwater. Therefore, there are currently some treatment equipment specifically for kitchen waste, which generally include crushing devices and conveying devices. , drying device, collection device. Existing conveying devices generally convey kitchen waste through the pushing force of rods, and some use screw rods to convey. The materials rotate with the high-speed spiral blades, and due to the existence of centrifugal force, the materials are conveyed along with the spiral blades. However, its transmission efficiency is relatively low, and because kitchen waste is a liquid-solid mixture, it...
