Detailed ways

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Figure 1, the fully automatic flushing straight filter includes a filter tank 10, and a filter element 100 is provided in the filter zone 11 of the filter tank 10;

The filter element 100 is provided with one or more;

The filter element 100 includes a filter element housing 110, the filter element housing 110 is provided with a water production pipe, and the filter layer is between the water production pipe and the filter element housing 110;

The filter layer is provided with a filter material, the filter material is composed of several mutually independent fillers, the density of the filter material is less than the liquid to be filtered so that the filter material can be in a floating state in the straight filter; one case of the filler material is EPS filter beads;

A specific structure of the filter element 100 can refer to the technology disclosed in CN208436453U;

In conjunction with the contents shown in Fig. 2, the filter tank 10 is provided with a cleaning tank 20, and the cleaning tank 20 is connected to the filter layer of the filter element housing 110 through the discharge pipe 300, and the quantity of the discharge pipe 300 is the same as the number of the filter core 100. Matching, each filter element 100 is connected to the cleaning tank 20 through the discharge pipe 300;

The cleaning tank 20 is independent from the filter layer and the sedimentation area, and does not affect the work of the cleaning tank 20 when working in some filter layers and sedimentation areas;

The filler in the filter element 100 can float up to the cleaning tank 20 with the water flow under the buoyancy of the water;

The cleaning pool 20 is also connected to the filter layer through the return pipe 30, and the end of the return pipe 30 away from the cleaning pool 20 is connected to the filter layer through the feed pipe 310, wherein the feed pipe 30 and the feed pipe 310 are one Whole or connected components, all of which achieve the same purpose, are the same as the technical means;

The inner diameters of the discharge pipe 300 , the return pipe 30 , and the feed pipe 310 are all larger than the outer diameter of the filler, so that the filler can pass through the discharge pipe 300 , the return pipe 30 , and the feed pipe 310 better.

The discharge pipe 300 is provided with a discharge valve body, which restricts the movement of the filler in the discharge pipe 300 by enabling the discharge valve body; the feed pipe 310 is provided with a feed valve body, which is The movement of the packing material in the feed tube 310 is restricted.

A control valve is provided between the cleaning tank 20 and the return pipe 30 , and the control valve controls the filler to enter the return pipe 30 from the cleaning tank 20 .

The lower part of the filter tank 10 is a settling zone 12 .

The cleaning tank 20 is provided with a sewage outlet, so that the impurities dropped by the filler in the cleaning tank 20 can be discharged from the sewage outlet.

When the filling material is transported, it can be transported with water, which is convenient for transmission; the cleaning tank 20 adopts flushing and cleaning, and when the filling material is extracted into the cleaning tank 20,

As shown in the figure, one way is that the cleaning pool 20 is located on the upper part of the filtering pool 10;

The discharge pipe 300 is connected to the upper part of the filter layer, and the feed pipe 310 is connected to the lower part of the filter layer;

The total volume of the filter material accounts for 70% of the total volume of the filter layer.

The total volume of the filter material accounts for 80% or 100% of the total volume of the filter layer. When it is 70-80%, it has better self-cleaning function.

The cleaning tank 20 is provided with a pipe communicating with the filtering area 11, and the inner diameter of the pipe is smaller than the outer diameter of the filter material.

One way is, referring to the technology in CN208916950U, the filter area 11 is provided with a guide cover 120, and the filter element 100 is arranged in the guide cover 120; the lower end of the guide cover 120 is open.

Above the filter area 11 is the water inlet area, and the specific structural state is not the content limited by this practical claim, so it will not be described in detail, and any that does not affect the normal use of the filter device can be used.

A working mode of the present invention is:

Take two filter elements 100 in the filter tank 10 as an example for illustration. When there are more than one, the steps are executed in sequence;

When working, the filter element 100 needs to be cleaned. First, the self-cleaning method of the filter element 100 can be used for cleaning. For details, refer to the self-cleaning method of the filter element in CN208436453U, when the self-cleaning is not clean enough;

First keep the second filter element 102 working normally, open the first discharge valve, the first feed valve, and the control valve, so that the other pipeline valve bodies are closed, and the filling material in the first filter element is extracted through the first discharge pipe 301 into the In the cleaning tank 20; when the filling material enters the cleaning tank 20, the originally gathered filling material becomes loose, and the impurities attached to it are more likely to come off after the filling material is loose;

The filling material enters the return pipe 30; the filling material enters the filter layer of the filter element 100 through the first feeding pipe 311 to complete a cleaning process, so that the filling material is in the first discharge pipe 301, the cleaning tank 20, the first inlet The material pipe 311 and the filter layer are in circulation, and the cycle time of the filter material is generally set at 1-2 minutes;

In order to make the filling materials return to the filter layer, the first discharge valve is now closed, and then the filter material in the cleaning pool is transported to the filter layer. Since the cleaning pool 20 is provided with a pipe body communicating with the filter area 11, keep the water flowing;

When all the filling materials return to the filter layer, the first filter element 101 is made to work normally;

Then, the second filter element is cleaned using the above process, the second discharge valve, the second feed valve, and the control valve are opened, so that the valve bodies of other pipelines are closed, and the filling material of the second filter element is passed through the second discharge pipe. 302 into the cleaning pool 20;

Make the filling material enter the return pipe 30; the filling material enters the filter layer of the filter element 100 through the second feeding pipe 312 to complete a cleaning process;

One of the tasks of the cleaning pool is:

Make sure that the cleaning area is full of water before starting cleaning;

When flushing starts, there may be water in the cleaning tank 20 that is quickly sucked into the filter core of the lower filter area, resulting in uneven pressure up and down or the washing area is in an anhydrous state. The pipe body, when the pressure in the filter area is greater than that in the cleaning pool, the water will automatically flow upwards into the flushing area to ensure that the upper and lower pressures are balanced, and the pumping action is guaranteed to proceed normally.

In one case, the pump body adopts a flexible pump to realize the functions of conveying and stirring. When the filter material is agglomerated into small pieces, it passes through the flexible pump, and the pump body can stir and split it and then transport it into the pipeline. The specific stirring method of the flexible pump adopts available technology.

Wherein, it is only necessary to set up pump bodies and other technologies for extracting and transporting the filling material to realize this function, so no further details are required.

It will be clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the general spirit and concept of the present invention. They all fall within the protection scope of the present invention. The protection scheme of the present invention shall be based on the appended claims of the present invention.
