Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a fine grid press for sewage treatment. Background Art

[0002] In the sewage treatment process, the fine grid press is an important equipment for solid-liquid separation. It intercepts the solid particles in the sewage through the grid and squeezes out the water in the solid particles by the pressing function to achieve the purpose of solid-liquid separation. However, there are some problems in the use of the existing fine grid press, such as the grid frame and the grid body are difficult to quickly disassemble and the poor sealing between the two and the press housing after installation. These problems affect the use efficiency and performance of the fine grid press.

[0003] First, the grid frame and grid body are key components of the fine grid press and need to be cleaned and maintained regularly. However, the existing fine grid press usually requires a complicated operation process when disassembling the grid frame and grid body, which is not only time-consuming and labor-intensive, but also easy to damage the equipment. This increases the maintenance cost of the equipment and reduces the efficiency of the equipment.

[0004] Secondly, the poor sealing between the grille frame and grille body and the press housing after installation is also an urgent problem to be solved. Due to poor sealing, sewage is easy to leak from the gap, resulting in poor solid-liquid separation and even possible environmental pollution. In addition, poor sealing may also cause internal corrosion and damage to the equipment, further reducing the service life of the equipment. For this reason, we provide a fine grille press for sewage treatment. Utility Model Content
