The following is about the working principle and technology of the back flushing filter:
Filtration medium: backwash filters typically employ mesh, fine pore or multi-layer media to perform the filtration function. The filter medium can be made of different materials and pore size according to the requirement so as to adapt to different particle sizes and filtering requirements.
Filtrate inlet and outlet: the backflushing filter has a filtrate inlet and a filtrate outlet, solid particles being trapped on the filter media as the liquid passes through the media, and clean liquid being discharged through the outlet.
Backwash mechanism: the backflushing filter is backflushed for a certain time interval to remove the accumulation on the filter medium. The back flushing can be performed by pouring water, blowing gas and the like, and the compressed air or clean water reversely passes through the filter medium to flush out accumulated solid particles and is discharged through a sewage outlet.
And (3) a control system: backflushing filters are typically equipped with a control system for monitoring and controlling the time, frequency and duration of backflushing. Suitable backwash parameters may be set according to different application requirements.
In order to achieve a better cleaning effect, the filter screen of the conventional straight-barrel type back flushing filter is generally designed to be fixed in the filter through a sectional structure, the conventional filter screen is cleaned by manual disassembly at intervals, and then the cleaned filter screen is reloaded into the filter to keep the long-term filtering effect of the filter.
However, the existing straight-tube filter has few researches on dechlorination and denitration, and the applicant carries out simple structural transformation on the existing straight-tube backwash filter, so that the effectiveness of filtration is ensured on one hand, certain technical effects on dechlorination and denitration are also ensured, and the filter is remarkable in the practical application process and effect, and is suitable for comprehensive popularization and application.
Disclosure of utility model
In order to solve the technical problems in the background technology, the utility model provides a backwash filter, which adopts the following technical scheme:
The back flush filter comprises a shell and a filter screen, wherein the filter screen is used for filtering impurities, the shell is made of metal materials, the shell is divided into a shell a and a shell b for achieving the effect of disassembling the filter screen, a water inlet and a flange a are arranged on the shell a, a water outlet, a flange b, a sewage outlet and a draining port are arranged on the shell b, the flange a and the flange b are used for connecting the shell a with the shell b, a fixing ring is arranged in the shell b and used for fixing the filter screen, the filter screen is prevented from moving, the fixing ring is connected with the shell b through a fixing piece, and the lower part of the fixing ring is communicated with the sewage outlet which is used for back flush sewage.
The utility model has the core improvement that the filter screen is of a double-layer hollow structure, namely a filter screen a and a filter screen b, the filter screen a and the filter screen b are connected through a connecting piece to form a whole, the outer ring openings of the filter screen a and the filter screen b are sealed through rubber rings, activated carbon is filled between the filter screen a and the filter screen b, the activated carbon is used for dechlorination and denitration, when the activated carbon needs to be replaced, the activated carbon is taken out of a shell, the rubber rings are taken out, then the activated carbon is flushed out by water, then new activated carbon is filled between the filter screen a and the filter screen b, finally the filter screen a and the filter screen b are sealed through the rubber rings, and then the filter screen a and the filter screen b are filled into the shell again for continuous use.
Preferably: in order to facilitate the replacement of the activated carbon, the right sides of the filter screen a and the filter screen b are arc-shaped structures.
Preferably: in order to improve the service life of the equipment, the materials of the filter screen a and the filter screen b are stainless steel.
Compared with the prior art, the invention has the following advantages:
Through structural transformation of the filter, the filter can solve the technical problems of dechlorination and denitration, and the filter screen can be quickly replaced, has a good effect in the actual application process, and is suitable for comprehensive popularization and application.
