Reversible diatomaceous earth filter

Aiming at the problems of the existing swimming pool water filtration equipment, the utility model provides a reversible diatomite filter, which has high filtration precision and strong filtration capacity and is suitable for large swimming pools.

In order to solve the above-mentioned technical problems, the technical scheme adopted by the present utility model is:

Reversible diatomite filter, including filter, hair filter, sewage inlet, drain, five-way valve, motor, hair filter is installed at the rear of the sewage inlet.

The sewage inlet is connected with the five-way valve, and the five-way valve is connected to the filter inlet pipe, the filter outlet pipe and the sewage pipe, and the filter inlet pipe and the filter outlet pipe are installed at both ends of the filter.

The filter includes a plurality of filter assemblies, and the filter assembly includes a filter frame, a filter plate and a pull rod. Multiple filter plates are installed between the filter frames, and the pull rod fixes the filter frame. The filter assembly water inlet and the filter assembly water outlet of the multiple filter assemblies are respectively It is connected with the filter inlet pipe and the filter outlet pipe, the lower end of the five-way valve is provided with a water pump, and the motor is connected with the water pump.

It includes an auxiliary cartridge, which is connected with the water inlet pipe at the lower end of the five-way valve through an auxiliary tube.

There is a filter screen inside the hair filter.

Install filter cloth on both sides of the filter plate.

The filter assembly is parallel to the inlet pipe.

beneficial effect

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

The components of the embodiments of the invention generally described and illustrated in the drawings herein may be arranged and designed in a variety of different configurations.

Accordingly, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely representative of selected embodiments of the invention.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present invention.

In order to solve the problem that swimming pool water filtering equipment cannot filter large swimming pools, the utility model provides a reversible diatomite filter, which can filter a large amount of sewage with high efficiency and high precision.

The working principle of the utility model is as follows:

The pool water enters the hair filter and comes out through the water pump, then enters the five-way valve and enters the filter from the filter inlet pipe. The filtered water comes out from the filter outlet pipe 10 and enters the five-way valve and finally enters the swimming pool.

When the filter cloth in the filter becomes dirty after a period of use, use the five-way valve for backwashing.

Sewage comes out of the hair filter and then enters the five-way valve through the water pump and enters the filter from the outlet pipe of the filter. The filter cloth on the 10 side of the outlet pipe of the filter is washed, and the sewage comes out from the inlet pipe of the filter and enters the five-way valve and finally drains.

When it is filtered again, the pool water enters the hair filter and comes out and sucks the diatomite in the auxiliary cartridge, and then enters the five-way valve through the water pump and enters the filter from the outlet pipe of the filter.

The water containing diatomaceous earth is coated on the filter cloth for filtering, and then the filtered water enters the five-way valve from the filter inlet pipe and finally enters the swimming pool. When the filter cloth becomes dirty, perform the above repeated backwashing and then add water containing diatomaceous earth.

The above addition of diatomite is called film coating in this field, and backwashing is called mold release. Pay attention to the following points for film coating and mold release:

When coating the film, add a quantitative amount of diatomite to the machine in the way of circulation, or backwash the film to avoid the ultra-fine diatomite and the remaining diatomite on the other side from entering the swimming pool.

Coating and demolding are carried out at the same time. When coating, set the five-way valve to the backwash gear.

During filtration, the pressure is continuously increased, and when the maximum working pressure is reached or the pressure difference reaches 1KG, backwashing is performed.

Whether the backwash is terminated depends on the turbidity of the water, or the backwash time is set at 1-2min.
