The continuous sand-flowing filtering system is widely used in various water treatment occasions needing filtering, in particular to the purification treatment of industrial process water, sewage and industrial wastewater, and can remove suspended substances and colloidal substances in water. The existing continuous quicksand filtering system is designed more traditionally, wherein the cleaning method for quartz filtering sand is more complicated and traditional, the cost is higher, and the cleaning effect for the filtering sand is general.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a continuous running sand filtration system, simple structure, low cost, it is very energy-conserving convenient to the cleanness of crossing the filter sand moreover, clean effectual, can continuously carry out the automatic filtration sewage.

In order to achieve the above object, the present invention provides the following technical solutions:

this continuous flow sand filtration system is strained a section of thick bamboo including crossing the bottom and being hopper-shaped cylindric, strains a sealed intercommunication in top and has the inlet tube, strains a sealed intercommunication in bottom and has the bushing, and the perpendicular intercommunication in bushing side bottom has the drain pipe, and bushing bottom sealing connection has the solenoid valve, and the sealed intercommunication of output of solenoid valve has the sand return pipe, and the sand return pipe is connected with the air stripping pump, and the sand return pipe top communicates with straining a side top perpendicularly, and dust absorption belt cleaning device is installed to the interlude of sand return pipe.

As a further optimization of the technical scheme, the filter cylinder and the water inlet pipe are both made of stainless steel and are connected through welding.

As a further optimization of the technical scheme, the drain pipe and the drain pipe are both made of stainless steel, and the drain pipe is connected with the filter cylinder and the drain pipe through welding.

As a further optimization of the technical scheme, the sand return pipe is made of stainless steel and is connected with the filter cylinder through welding.

As a further optimization of the technical scheme, a fine filter screen is arranged at the communication part of the dust collection and cleaning device and the sand return pipe.

The beneficial effect of adopting above technical scheme is: when the continuous flowing sand filtering system is used, the filter cylinder can be fixed, the electromagnetic valve is closed, and the filter cylinder is filled with filtering sand. Sewage is put into the filter cylinder from the water inlet pipe, flows through the filter sand, enters the drain pipe and is discharged from the drain pipe, and pollutants are filtered by the filter sand. When sand washing is needed, the sewage can be stopped from being poured, the electromagnetic valve is opened, the gas pump is opened again, the filtered sand leaks into the sand return pipe, the dust absorption cleaning device is opened, pollutants in the filtered sand flowing through the sand return pipe are absorbed, and the filtered sand is clean. The air pump finally fills the filter sand into the filter cylinder from the sand return pipe, and the sewage can be filtered again. The continuous quicksand filtering system is simple in structure, low in cost, very energy-saving and convenient to clean filter sand, good in cleaning effect and capable of continuously filtering sewage automatically.

Detailed Description

Preferred embodiments of the continuous sand flow filtration system are described in detail below with reference to the accompanying drawings.

Fig. 1 and 2 show an embodiment of the continuous quicksand filtration system:

with reference to fig. 1 and 2, the continuous sand-flowing filtering system comprises a cylindrical filter cartridge 1 which is funnel-shaped and passes through the bottom, the top of the filter cartridge 1 is hermetically communicated with a water inlet pipe 2, the bottom of the filter cartridge 1 is hermetically communicated with a leakage pipe 3, the bottom of the side surface of the leakage pipe 3 is vertically communicated with a drain pipe 4, and the drain pipe 4 is provided with a valve. The bottom of the leakage pipe 3 is hermetically connected with an electromagnetic valve 8, the output end of the electromagnetic valve 8 is hermetically communicated with a sand return pipe 5, the sand return pipe 5 is connected with an air stripping pump 7, the top of the sand return pipe 5 is vertically communicated with the top of the side surface of the filter cylinder 1, and a dust collection cleaning device 6 is installed in the middle section of the sand return pipe 5.
