Description

a centrifugal filter

technical field

The utility model relates to the technical field of sewage filtration, in particular to a centrifugal filter.

Background technique

At present, in the liquid filtration or filtered waste residue and waste liquid discharge in the pharmaceutical, chemical, light industry and other industries, there are solid-liquid mixed liquids. Some companies have carried out unified treatment in order to separate the mixed liquids and adopted various methods. Generally, the sedimentation method is used to deposit the mixed liquid in a sedimentation tank or a sedimentation tank for a long time. Although it can separate the solid and liquid mixed liquid, this requires a sedimentation tank or a sedimentation tank, which occupies a large area and requires a period of time and investment. The cost is high, the liquid and the solid cannot be separated quickly, and it is not environmentally friendly; the second is the mechanical separation method. Generally, after filtering by the filter equipment, the mixed liquid still remains in the equipment, and some solid and liquid mixed liquid are squeezed by a filter press. Pressure interception separation or drum-type accelerated rotation separation, although it is preferred to the precipitation method in the process of solid-liquid separation, but it is relatively slow to process a large amount of mixed liquid in the operation process, it is labor-intensive and time-consuming, and it cannot be automatically unloaded, and the operating cost It is expensive, and it is difficult to achieve the effect of rapid separation, and due to the improvement of national emission standards, the current separation technology cannot meet the needs of market development.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the embodiments and accompanying drawing 1, and the content mentioned in the implementation mode is not a limitation of the utility model.

Example 1

Referring to Fig. 1 , a centrifugal filter includes a casing 4, a filter box 3 arranged in the casing 4, and a drive mechanism 1 for driving the rotation of the filter box 3, and the inner wall of the filter box 3 is provided with a filter membrane.

The driving mechanism 1 of the present utility model is a motor. When in use, the filter box 3 rotates at a high speed under the drive of the motor, and because the inner wall of the filter box 3 is provided with a filter membrane, the sludge and water are separated under the centrifugal force and the filter membrane. Under the action, it can be separated quickly. The filter membrane can be replaced according to different types of waste liquids. Due to the cooperation of the centrifugal force and the filter membrane, the sewage treatment efficiency is high and the effect is good. In addition, the utility model occupies a small area, has a small investment cost and is easy to use.

Further, the driving mechanism 1 includes a motor and a rotating shaft 2 connected to the output end of the motor, and the filter box 3 is detachably connected to the outer wall of the rotating shaft 2 .

The utility model makes installation and replacement of the filter box 3 more convenient by setting the detachable filter box 3 .

Further, an accommodation space 5 is provided between the filter box 3 and the casing 4 .

This new type of use provides an accommodation space 5 between the filter box 3 and the shell 4, so that the filtered water enters the accommodation space 5 after being discharged from the filter box 3, and then discharged in a concentrated manner, so that the sewage can be better treated in a unified manner.

Further, a water inlet 6 is provided in the middle of the upper end of the casing 4 , and the rotating shaft 2 passes through the water inlet 6 and passes out of the casing 4 .
