The present invention discloses an adjustable filter head of a cast-in-place filter plate. The adjustable filter head comprises a filter cap, a filter seat, a filter rod and a template. The filter cap forms a thread and fixed connection with the filter seat. The filter seat respectively forms thread connections with the filter rod and the template. The filter rod and the template are provided with fixation clamping strips, wherein the fixation clamping strips are mutually matched. The filter rod can be adjusted to move up and down in the filter seat, and has good fastening property. According to the present invention, with adopting the template to install and control, the uniformity of the filter seat product size, the tight match of the filter seat and the template, the levelnesses of the template and the top surface of the filter seat are controllable, it is ensured that the levelnesses of the cast-in-place reinforced concrete filter plate is in a controllable range; with the thread adjustment of the filter seat and the filter rod, the backwashing gas inlet hole and the gas inlet strip crack of each filter rod are respectively at the same height level so as to fully meet the quality requirements; with the interference match and fixation of the matched clamping strips arranged on the filter rod and the filter seat or the template, the backwashing vibration can not cause the position change of the filter rod. With the present invention, the long term operation effects of air-water backwashing and filtering of the filter tank are ensured.
Description
Technical field [0001] The invention belongs to the technical field of water treatment, and relates to a cast-in-place filter plate adjustable filter head. Background technique [0002] Filtration, as a key process in water plants and sewage treatment plants, plays a final check on the treatment effect of the entire system, and its operating conditions directly affect the quality of the water produced by the water plants. The regeneration of filter capacity is the key to stable and efficient operation of the filter. In order to improve the recovery effect of the sewage interception capacity of the filter layer, with the advancement of technology, in recent years, water plants have been newly built and reconstructed. The filter tanks are mostly used: first gas washing, then gas and water combined washing, and finally water washing. A relatively satisfactory result has been achieved. [0003] The most important thing for the air and water backwashing of the filter is to control the...
