Description

Technical Field

[0001] This utility model relates to the field of filter press equipment technology, and in particular to a filter press device for starch residue. Background Technology

[0002] Starch has a wide range of uses, including edible applications and industrial uses such as printing paste preparation, textile sizing, paper sizing, and tablet compression. During starch production, a large amount of starch residue is generated, which contains a high moisture content and requires dehydration. Current technology typically uses filter press dehydration to squeeze and dehydrate the starch residue. However, during production, some starch residue remains on the filter belt of the filter press equipment, and it cannot be cleaned and recycled in a timely manner, leading to increased raw material processing losses. Furthermore, the long-term residue residue can contaminate fresh starch residue, affecting the filtration effect.

The scraper block 43 slides back and forth along the axis of the cleaning component and is in close contact with the working surface of one of the cleaning plates 31.

[0022] See Figures 1 to 3 Preferably, the filter press belt assembly of this utility model is provided with a top plate 5 above it, and a driving member 41 is fixedly connected to the top plate 5. The output end of the driving member 41 is fixedly connected to a screw 4 that drives the scraping block 43 to reciprocate. An abutment block 42 that drives the cleaning member to rotate is screwed onto the screw 4.

[0023] See Figures 1 to 3 In addition, the output end of the abutment block 42 of this utility model is provided with an idler wheel 32 that drives the cleaning component to rotate in one direction, and the rotation direction of the cleaning component is opposite to the transmission direction of the top filter belt.
