Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a device for measuring the expansion coefficient of a water treatment filter layer. Background Technology

[0002] In water treatment production, process parameters directly reflect the operating effect of the water treatment equipment. Therefore, measuring process parameters can prevent increases in chemical and energy consumption due to deterioration of process parameters, thus saving energy and reducing costs. In reality, most devices for measuring the filter bed expansion coefficient are relatively simple and lack adjustable height according to the actual conditions of the filter bed. They also require constant manual support, and the expansion height measurement is prone to errors due to filter bed expansion and loosening during backwashing, affecting the accuracy of the expansion coefficient. Furthermore, the measuring scale needs to be inverted and cleaned after each use, which is inconvenient. These are practical problems discovered in production, necessitating improvements and optimizations to the measuring devices, increasing measurement accuracy, and streamlining operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Combined with appendix Figure 1-6A device for determining the expansion coefficient of a water treatment filter layer includes a housing 1. A small hydraulic control center 2 is fixedly installed inside the housing 1. A supporting fixture is provided outside the housing 1. A hydraulic cylinder 10 is fixedly installed at the bottom of the housing 1. A connector 12 is fixedly connected to the output end 11 of the hydraulic cylinder 10. A measuring ruler 13 is fixedly connected to the lower end of the connector. Multiple detection boxes 14 are arranged alternately on both sides of the measuring ruler 13. Sliding grooves 20 are symmetrically opened on both sides of the measuring ruler 13. A sliding strip 19 is slidably installed in each sliding groove 20. A bottom seal 18 corresponding to each detection box 14 is fixedly installed on each sliding strip 19. A sliding sleeve 15 is slidably fitted on the upper end of the measuring ruler 13. The sliding sleeve 15 is fixedly connected to two sliding strips 19. A contact base plate 22 is provided at the bottom of the measuring ruler 13.

[0018] As a further embodiment, a sliding bolt 16 is slidably provided on the sliding sleeve 15, and a bolt hole is provided on the measuring ruler 13.
