Problems solved by technology

[0004] However, after the above-mentioned filter collects the dirt, it needs to be backwashed to remove the accumulated solid particles. However, if the backwash is to be carried out, it must be shut down, the sewage treatment process is interrupted, and additional backwashing is required. Pool, equipped with the equipment required for combined air-water backwashing system
It can be seen that such existing sewage treatment methods have the problems of high downtime cost, low treatment efficiency, and large equipment footprint

Embodiment Construction

[0032] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0033] Such as figure 1 , figure 2 As shown, the filter includes an air compressor 1, a pipeline pump 2, an empty pipe shaft 3 and a main drive mechanism 4, the main drive mechanism 4 is connected with the empty pipe shaft 3 and can drive the empty pipe shaft 3 to rotate intermittently around its axis. degree rotation, several discs 5 are connected in series along the axial direction on the empty pipe shaft 3, and the number of discs 5 is at least three. Generally, more than three discs 5 can meet the daily sewage filtering requirements. Each disc 5 is concentrically arranged with the hollow tube shaft 3 and the two are fixedly connected. Each disc 5 has several independent filter cavities 6 inside, and each filter cavi...

Abstract

The invention provides a rotary disc type filter, belonging to the technical field of sewage treatment equipment, and aiming at solving the technical problems that the existing filter is low in sewage treatment efficiency, etc. The rotary disc type filter comprises an air compressor, a pipeline pump, an air pipe shaft and a main driving mechanism, wherein the main driving mechanism is connected with the air pipe shaft and can be used for driving the air pipe shaft to make intermittent division rotation around the self axis; the air pipe shaft is connected with discs in series along the axis direction; the discs are fixedly connected with the air pipe shaft; each disc is internally provided with a filtering cavity body, and two filter screens are respectively arranged at the two sides of the filtering cavity body; the filtering cavity bodies are respectively communicated with an inner cavity of the air pipe shaft; a static inner guide pipe is inserted and connected in the inner cavity of the air pipe shaft; the static inner guide pipe is provided with a plurality of spray suction holes along the radial direction, and the positions of the spray suction holes correspond to those of the discs; a backflushing mechanism is aligned to one of the filter screens; the air compressor and the pipeline pump are respectively communicated with the static inner guide pipe or the backflushing mechanism; the objects communicated with the air compressor and the pipeline pump are arranged in a staggered way. After the rotary disc type filter is adopted, continuous operational capability can be realized, and the sewage treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment and relates to a rotary disc filter. Background technique [0002] In the prior art, sand filtration is used for filtering sewage. After the equipment has been in operation for a period of time, solid particles will accumulate in the filtering mechanism. [0003] As disclosed in the patent (CN201020532974.1), a rotary disc microfilter includes a drum that can be driven to rotate, at least one filter mechanism mounted on the drum and concentric with it, a long groove arranged in the drum, and a backwashing mechanism . A backwash drive mechanism that drives the backwash mechanism to swing. The filter mechanism includes a pair of filter discs arranged in parallel on the above-mentioned drum. The filter discs are installed on the above-mentioned drum through a bracket, and the pair of filter discs share A bracket, a pair of filter discs are sealed by a top cover plate, and an openi...
