Anti-splash device for screw extruder

Abstract

The invention provides an anti-splash device for a screw extruder. The anti-splash device comprises a feed box, a discharge box, a screw spindle, a water filter system and a transmission system, wherein the water filter system comprises a dewatering screen, a dewatering screen water falling funnel and a water shield; the dewatering screen water falling funnel is arranged below the dewatering screen; a plurality of support plates that are perpendicular to the outer side wall of the dewatering screen are arranged on the outer side wall of the dewatering screen and uniformly arranged in a circumferential direction and a length direction of the dewatering screen; a liquid baffle surrounds the outer side and an opening in the lower part of the dewatering screen through the support plates; and the water baffle is arranged on the outer side of the liquid baffle. Since the liquid baffle is arranged on the outer side of the dewatering screen, water squeezed by wringing equipment is effectivelyprevented from being splashed on the water shield and then permeating out from a gap in the water shield, and accordingly, environmental pollution and waste of water resources and labor force are avoided; and as water squeezed by a screw wringing machine is reused, the water resources are saved, and the cost of a factory is lowered.

Description

technical field [0001] The invention belongs to the field of drying equipment, in particular to a liquid splash prevention device for a screw squeeze dryer. Background technique [0002] In the screw squeezer in the prior art, during the operation of the equipment, the moisture in the material is strongly squeezed and hits the waterproof cover with a very strong impact force, and at the same time, part of the water will penetrate through the gap on the waterproof cover If it falls on the ground or equipment outside, it will become moldy and smelly after a long time, causing environmental pollution, increasing the labor time of workers and wasting water resources. [0003] And when the screw squeezer squeezes cassava dregs and other materials, since the cassava dregs always contain a small amount of unwashed starch in the production process, during the screw squeeze dehydration process, the materials and the screw squeezer blades, The dehydration sieves rub against each othe...

AI Technical Summary

Problems solved by technology

[0002] In the screw squeezer in the prior art, during the operation of the equipment, the moisture in the material is strongly squeezed and hits the waterproof cover with a very strong impact force, and at the same time, some water will penetrate through the gaps in the waterproof cover If it falls on the ground or equipment outside, it will become moldy and smelly after a long time, causing environmental pollution, and also increasing the labor time of workers and wasting water resources.

[0003] And when the screw squeezer dries materials such as cassava dregs, since the cassava dregs always contain a small amount of unwashed starch in the production process, during the screw squeeze dehydration process, the materials and the blades of the screw squeezer, The dehydration sieves rub against each other violently, making the starch in the material gelatinized and sticky, causing the material to rotate with the screw spindle. In some cases, the moisture content of the finished product is high, and the output is severely reduced. In severe cases, the screw squeezer cannot work normally.
