Technical Field

The invention relates to the technical field of sewage treatment equipment, in particular to an automatic fine brushing and dirt removing fine filter.

Background

After the sewage is subjected to primary treatment, fine particle impurities are still mixed in the sewage. In general, a considerable amount of floating materials and suspended particles are discharged to a receiving water body at a combined treatment sewage overflow port, for example, in a densely populated living area, a small area with incomplete facility functions, a small or medium-sized factory, and the like.

After accumulating day and month, the small-particle impurities can cause the blockage of a sewage discharge system, influence the normal work of other follow-up sewage treatment equipment and even influence the service life of the sewage treatment equipment in serious cases.

Based on the problems existing in the sewage treatment process, a fine filter device suitable for being used in a sewage treatment system is urgently needed to solve the problems of filter screen blockage, garbage separation and the like, so that the treated sewage can reach the discharge standard to protect the receiving water body.

Detailed Description

The following is combined with the attached drawings. The present invention is further explained.

The specific structure of the scheme is as shown in fig. 1, a fine screen cylinder 2 is nested in an outer cover 1, the top end of the fine screen cylinder 2 is fixedly connected with the bottom of the outer cover 1 through an upper flange 11, and the bottom end of the fine screen cylinder 2 is fixedly connected with the bottom of the outer cover 1 through a lower flange 11.

In addition, a driving motor 5 is provided on the top of the housing 1, and a rotating shaft of the driving motor 5 is connected to a driving shaft 4 and drives the driving shaft 4 to rotate together. The drive shaft 4 passes through the housing 1 into the interior of the fine screen cylinder 2.

A brush barrel 3 is arranged in the fine screening barrel 2, the top end of the brush barrel 3 is fixedly connected with a driving shaft 4, and the brush barrel can be driven by the driving shaft 4 to rotate together.

The outer wall of the brush barrel 3 is provided with a brush 31, the brush 31 is spirally distributed along the outer wall of the brush barrel 3, and the brush 31 is abutted against the inner wall of the fine screen barrel 2.

The lower part of the outer cover 1 is provided with a water inlet 7, and the water inlet 7 is communicated with the inside of the fine brush barrel 2. A lower filter cartridge 6 is mounted at the water inlet 7, and the lower filter cartridge 6 is fixed to the lower flange 12. A water outlet 8 is arranged on the side wall of the outer cover 1 and is communicated with the inner cavity of the outer cover 1.

In addition, as shown in fig. 2, two handles 13 are symmetrically provided on the side wall of the housing for easy installation.

The working principle of the scheme is as follows:

the sewage impurity still has tiny granule impurity to mix wherein after primary treatment, from water inlet 7 under the pressure condition, gets into the inner chamber of fine screen section of thick bamboo 2 through straining a section of thick bamboo 6 down, along with the continuous rising of water level, when the water level gauge detects the water level and targets in place the back, driving motor begins automatic operation. For the treatment of the sewage impurities entering the fine screening machine, the spiral brush automatically cleans the screen of the fine screening cylinder 2 in rotation, and simultaneously, the sediment is automatically precipitated and separated, and the filtered sewage reaches the standard and is discharged from the water outlet 8.

The main structure of this scheme, for example: the outer cover, the fine screen cylinder, the brush cylinder, the driving shaft, the lower filter cylinder and the like are all made of stainless steel materials, so that the stainless steel brush has super-strong corrosion resistance, and the service life of the product is greatly guaranteed. The whole structure is very simple, the workload of subsequent maintenance is very small, and the maintenance cost is greatly reduced. In actual use, the sewage treatment device is matched with other sewage treatment devices for use, and the treatment efficiency is higher.

The difficult problem of filter screen jam and waste classification in the sewage treatment process can effectively be solved to this scheme to make the sewage after handling can reach emission standard, in order to protect the water of receiving.

The application environment of the scheme is usually at a confluence sewage treatment overflow port, and a considerable amount of floating objects and suspended particles are usually discharged to a receiving water body in the place. Such as densely populated living areas, residential areas with facilities with poor functionality, small and medium-sized factories, etc.
