Filtering device for solving the problems that filter screen cannot be automatically replaced and cannot be automatically cleaned

Abstract

The invention relates to the technical field of drinking water purification, and discloses a filtering device for solving the problems that a filter screen cannot be automatically replaced and cannot be automatically cleaned, the filtering device comprises a shell, and through cooperative use of the filter screen, a rotating plate, a baffle, a first connecting rod, a second connecting rod and a large gear, sewage is automatically and intermittently introduced during sewage treatment; meanwhile, the filter screen can be automatically replaced when sewage is filtered, manual replacement is avoided, the situation that the filtering effect of the sewage is affected due to the fact that manual replacement is not conducted in time is avoided, through cooperative use of a first rotary disc, a second rotary disc, a movable block and a brush plate, the filter screen can be automatically cleaned, and therefore manual cleaning is not needed; and compared with the prior art, the sewage treatment device has the advantages that more time and labor are saved, the working efficiency during sewage treatment is improved, the two steps of automatic replacement of the filter screen and automatic cleaning of the filter screen are linked through cooperative use of the first disc and the limiting sleeve, so that the linkage of the whole device is improved, and the operation is simpler.

Description

technical field [0001] The invention relates to the technical field of drinking water purification, in particular to a filter device that solves the problem that the filter screen cannot be automatically replaced and cleaned. Background technique [0002] With the development of industry, the pollution of existing water sources is becoming more and more serious, and with the improvement of living standards, people's requirements for the quality of drinking water are getting higher and higher. However, drinking water from rivers and lakes contains a large amount of Bacteria, microorganisms, and even sediment. Wherein when carrying out drinking water purification, at first need use filter screen to remove bigger particle, but existing filtering device is set up comparatively simple, on the one hand, need artificial timing to replace filter screen when filtering, and when carrying out filter screen replacement The device needs to be shut down for operation, which is time-consu...

Problems solved by technology

Wherein when carrying out drinking water purification, at first need use filter screen to remove bigger particle, but existing filtering device is set up comparatively simple, on the one hand, need artificial timing to replace filter screen when filtering, and when carrying out filter screen replacement The device needs to be shut down for operation, which is time-consuming and labor-intensive for repeated operations, and consumes a lot of energy when the device is repeatedly opened and closed. On the other hand, when filtering, residues will remain on the surface of the filter screen, which requires manual cleaning. If the surface residue is not removed in time, the filter screen will be blocked, which will affect the filtering effect of the filter screen, and finally affect the purification effect of drinking water

[0003] Aiming at the deficiencies of the prior art, the present invention provides a filter device that solves the problem that the filter screen cannot be automatically replaced and cleaned automatically, which has the advantages of automatically cleaning the filter residue and automatically replacing the filter screen, and solves the problem of relatively single function in traditional sewage filtration. The problem is to ensure that the operation of the device is more time-saving and labor-saving, and the filter screen can be replaced automatically during the process of sewage filtration, so that manual replacement is not required, which saves time and effort, and the filter screen is in use It can be cleaned automatically during replacement without manual cleaning, thereby improving the work efficiency of sewage treatment and increasing the intelligence of the device when it is used
