Description

Technical Field

[0001] The utility model belongs to the technical field of disc filters, in particular to a vertical disc filter truck device. Background Art

[0002] The vertical disc filter is a solid-liquid separation equipment that uses vacuum as the filtering power to separate the solid and liquid in the slurry. It adopts advanced technologies such as filter disc guide frame guidance, variable speed stirring, back-blowing unloading and automatic centralized lubrication. It is a dehydration equipment with excellent performance and reliable use.

[0003] The vertical disc filter is composed of multiple circular filter discs, each of which is composed of multiple separate fan-shaped plates. Each fan-shaped plate is a separate filter unit. The filter cloth is made of cloth and is placed on the fan-shaped plate to form a filter chamber. The filter disc is driven by a motor through a reducer and an open gear transmission. The filter disc rotates clockwise. The slurry in the filter chamber is attached to the filter disc to form a filter cake in the adsorption area with the help of the pressure difference formed on both sides of the filter medium by the vacuum pump. The agitator rotates to prevent solid precipitation. After the filter cake leaves the liquid surface, it continues to remove moisture under the action of vacuum. The filtrate passes through the filter cloth, passes through the filter liquid pipe, and is discharged from the distribution head. The filter cake is discharged by back-blowing in the discharge area and falls into the discharge trough. The entire operation process is carried out in a continuous cycle.

[0004] The filter cloth of the disc filter needs to be replaced after a long period of use. In the process of replacing the filter cloth, the fan-shaped plate needs to be removed first. When a fan-shaped plate is removed, the center of gravity of the entire filter disc will change. Under the action of gravity, the filter disc will rotate, which may easily cause injuries to people and pose a safety hazard. Utility Model Content
