Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, and more specifically, to a belt filter. Background Technology

[0002] Wastewater refers to water discharged from domestic and industrial sources that has been polluted to a certain extent. Water that has lost its original function is simply called wastewater. It mainly consists of water used in daily life, which contains a relatively high amount of organic matter and is relatively easy to treat. However, some industrial wastewater contains large amounts of filamentous matter and solid particles that cannot be separated using conventional filtration methods. It can only be intercepted manually, resulting in harsh working conditions and low efficiency. Existing wastewater treatment methods often struggle to remove filamentous matter, so we have proposed a belt filter. Utility Model Content

[0022] Among them, multiple wear-resistant blocks 5 are fixed on the upper part of the inner wall of the main housing 1, and the wear-resistant blocks 5 are placed on the upper side wall of the filter belt 2, so that the upper part of the filter belt 2 can be supported by the wear-resistant blocks 5.

[0023] The main housing 1 has an inspection hole 22 on one side, through which staff can inspect the inside of the main housing 1.

[0024] The main housing 1 has an annular plate 7 fixed on one side, and the filter belt 2 is slidably disposed in the annular plate 7. Brushes 8 are fixed on both the upper and lower sides of the inner wall of the annular plate 7, and the two brushes 8 are placed on the upper and lower sides of the filter belt 2 respectively. The impurities on the upper and lower sides of the filter belt 2 can be brushed off by the two brushes 8.

[0027] The working principle and usage process of this utility model are as follows: By pouring sewage into the filter belt 2 inside the main housing 1, the material is filtered by gravity. The filter belt 2 can filter filaments, solid particles, etc. During operation, the filter belt 2 is immersed in the disinfection tank for a certain period of time. The filter belt 2 can be sprayed and rinsed by the spray pipe 23. After rinsing and regeneration, the filter belt 2 enters the next stage of filtration. The filtrate is collected by the receiving tray 3 and discharged into the collection system, and then re-enters the sewage treatment system. The filtrate is discharged after biochemical treatment to meet the standards.
