The cleaning of the sand filter layer in the filtration process is always a problem, and two cleaning modes are widely used at present: siphon backwashing and air-water backwashing. Both approaches solve the problem of sand cleaning to some extent, but all suffer from some drawbacks.
The traditional siphon backwashing is an earlier-applied backwashing process, and has the problems of uneven backwashing and incomplete backwashing in the actual application process, so that various problems of higher turbidity of effluent, sand filtration hardening, frequent backwashing and the like in the use process of the filter tank are caused.
The air-water backwashing can better solve the problem of cleaning the sand filtering layer, but the equipment is more, and the air-water backwashing water pump, the valve, the control instrument, the control system and the like are included, so the investment cost is high; meanwhile, because the equipment is complex, the problems of the equipment can be solved timely due to the fact that the number of maintenance personnel is large and the professional quality is high, the water production safety is guaranteed, and meanwhile, the air-water backwashing equipment is high in power consumption and maintenance cost, so that the running cost of a water plant is increased, and therefore, the improvement room exists.
Disclosure of Invention
The utility model aims at: the balanced backwashing system is provided for solving the problem that the running cost of a water plant is increased due to high power consumption and high maintenance cost of air-water backwashing equipment.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the balanced back flushing system comprises a filter main body, wherein an inner cavity of the filter main body is connected with a balanced back flushing mechanism main body, the top of the balanced back flushing mechanism main body is communicated with a back flushing siphon pipe, one side of the back flushing siphon pipe is communicated with a siphon breaking pipe, the tail end of the back flushing siphon pipe extends into a siphon well communicated with the outside of the filter main body, and one side, far away from the back flushing siphon pipe, of the filter main body is communicated with a filter tank water inlet pipe.
As a further description of the above technical solution:
the bottom of the inner cavity of the filter body is fixedly connected with a filter plate, and a plurality of filter holes are formed in the top of the filter plate.
As a further description of the above technical solution:
the inner cavity of the filter chamber main body is filled with a filtering part.
As a further description of the above technical solution:
the tail end of the water inlet pipe of the filter tank is communicated with a water collecting channel which is fixedly arranged on one side of the filter tank main body.
As a further description of the above technical solution:
the tail end of the water inlet pipe of the filter tank extends into the water collecting channel.
As a further description of the above technical solution:
and a sealing gasket is embedded on one side of the filter tank main body corresponding to one side of the filter tank water inlet pipe, and the sealing gasket is a flexible plastic mat.
In summary, due to the adoption of the technical scheme, the beneficial effects of the utility model are as follows:
1. in the utility model, the balanced backwashing device is uniformly arranged in the filter tank, so that backwash water flow is uniformly distributed on the whole filter layer, uneven sand filtering layer formed by unbalanced fluctuation of the sand filtering layer due to uneven water flow is avoided, the sand filtering is prevented from being sucked out due to overlarge local backwash water flow, the filter tank after the balanced backwashing system is used, the sand filtering layer is completely cleaned, the dirt receiving capacity of the sand filtering layer is increased, the backwashing interval time is prolonged, water is saved, and meanwhile, high-turbidity primary filtered water is prevented from entering a clean water tank after backwashing is finished, so that high-standard water outlet is achieved.
2. According to the utility model, the filter tank after the balanced backwashing system is used, the sand filtering layer is completely cleaned, the dirt receiving capacity of the sand filtering layer is increased, the backwashing interval time is prolonged, water is saved, no additional air-water backwashing equipment is required, and the energy is saved and the environment is protected; the problems of complex operation and complex maintenance of equipment are avoided, and the use is more convenient.
