Description

TECHNICAL FIELD

[0001] The utility model relates to straw pretreatment equipment, especially a screw belt type straw stirring equipment with loosening teeth. BACKGROUND

[0002] The pretreatment and processing utilization of straw often involve the mixing of solid or semi-solid materials. The straw is either torn into long rods or broken into small particles or powder. Such irregular materials have poor flowability. In addition, the straw is sticky and loses flowability due to moisture absorption or saccharification, making it difficult to mix.

[0003] The existing built-in baffle rotating drum device for straw micro-thermal explosion pretreatment is not suitable for stirring and mixing in the process of adding an appropriate amount of water for straw solid or semi-solid biochemical processing (fermentation enzyme production, hydrolysis and saccharification), and the power consumption of the drum rotation is high.

[0004] There are devices that use rake stirring (plow rake structure) for vacuum drying as a device for the solid-state fermentation of powdered straw. However, when such devices are used for stirring and mixing of long and thin straw, the straw often winds around the stirring blades, causing stirring to be blocked and forming discharge blockage and other problems.

[0005] The utility model optimizes and improves the stirring equipment in view of the existing problems, aiming to provide a technical scheme that can effectively reduce energy consumption and improve stirring efficiency and stirring effect through the technical equipment. UTILITY MODEL CONTENTS

[0006] In view of the technical problems of the existing device, the utility model provides a screw belt type straw stirring equipment with loosening teeth.

[0007] In order to achieve the above-mentioned utility model purposes, the utility model adopts the following technical scheme:

[0008] A screw belt type straw stirring equipment with loosening teeth, comprising:

[0009] A tank body is provided with a feed pipe at the top and a discharge assembly at the bottom.

[0010] A stirrer is installed at the top of the tank body and comprises a stirring shaft extending into the tank body. The stirring shaft is provided with a double-screw belt paddle mechanism at different heights, and the double-screw belt paddle mechanism is provided with protruding loosening teeth.

[0011] A driving mechanism is connected to and drives the rotation of the stirrer.

[0012] Further technology of the utility model:

[0013] Preferably, the double-screw belt paddle mechanism comprises a connecting belt and a screw belt paddle connected by the connecting belt.

[0014] Preferably, the connecting belts are provided in several groups and are arranged on the stirring shaft in sequence from top to bottom.

[0015] Preferably, the loose teeth are arranged on the connecting belts of the double helical ribbon impeller, and the loose teeth on the same connecting belt are symmetrical to the stirring shaft.

[0016] Preferably, the loose teeth are arc-shaped loose teeth.

[0017] The beneficial effects of the present application are as follows:

[0018] During stirring, the motor drives the stirring shaft to rotate, the two shafts rotate towards each other during stirring, the stirring force generated by the double helical ribbon impeller blades turns the materials in a large range, one helical ribbon moves the materials to the two sides, the other helical ribbon moves the materials from the two sides to the inside, so that the materials are mixed and mixed back and forth, and part of the materials move along the axial direction under the pushing of the helical ribbon, thereby forming a convection circulation. During stirring, the straw filaments may be wound together, which is not conducive to cleaning, at this time, the loose teeth on the connecting plate are used to scatter and loosen the wound straw filaments, so as to improve the stirring treatment efficiency.

[0019] The present application has the advantages of reasonable design, the loose teeth are arranged on the connecting plate of the double helical ribbon impeller, the straw in a wet state is mixed and stirred, the winding of the intermediate straw is scattered, the stirring efficiency is effectively improved, and the pulping efficiency is high.
