Description

Technical Field

[0001] The utility model relates to the field of sludge dehydration filter press equipment, in particular to a sludge scraping structure of a sludge filter cloth. Background Art

[0002] For sludge carbonization treatment, drying and dehydration before the sludge enters the carbonization furnace is a key link. The applicant provides a new filter pressing solution, which stacks the filter cloth in an S shape in the filter cage, spreads the sludge to be filtered between the filter cloths, and presses the filter cloth downward through a vertical compression component (hydraulic cylinder drives the pressure block) to complete ultra-high pressure filtration. For example, the filtration method in the sludge filter pressing device of a deep sludge filter pressing and dehydration system disclosed in the existing patent application No. 202010077038.4.

[0003] The applicant has set a reversing roller on the upper section of one side wall of the filter cage to scrape the residual sludge on the surface of the filter cloth at the reversing roller position during the upward rewinding process. The applicant scrapes the sludge by placing the filter cloth against the reversing roller at the lower position of the midline of the reversing roller. Since the filter cloth is stacked in an S shape in the filter cage, the position of the filter cloth close to the introduction side of the reversing roller changes repeatedly during the rewinding process, so that the filter cloth is not close to the reversing roller and contacts the scraper to scrape the sludge. The filter cloth is easily drawn out to produce wrinkles, which affects the sludge scraping effect. Based on this, the applicant has improved and adjusted the sludge scraping structure.

[0024] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0025] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
