Description
Technical Field
The utility model relates to the technical field of water treatment equipment, in particular to an air-flotation backflushing water-saving type quick-cleaning sand cylinder filter.
Background
The sand jar filter is a common water treatment device, is widely used for water treatment of swimming pools, water treatment of circulating water culture, chemical industry, environmental protection water treatment, drinking water treatment, outdoor landscape water treatment and the like, and is a novel sand jar filter used in a front pretreatment system. The air-float backflushing device is designed for overcoming the defects that the conventional sand cylinder filter is difficult to backflush dirt completely after dirt blockage, a large amount of backflushing water is wasted, the frequent times of replacing quartz sand are increased and the like, and the air-float backflushing device utilizes the air pump to perform air-float backflushing so as to achieve the effective purposes of saving time and materials, saving water and rapidly removing the dirt on a sand layer.
In the using process of the conventional sand cylinder filter, dirt deposited by filtering the sand layer needs to be backflushed and discharged for a long time by using a large amount of clean water, and even if the dirt is backflushed completely, the dirt is difficult to clean. Because the dirt on the sand layer is continuously accumulated, deposited and blocked, the filtering flow of the sand cylinder is gradually reduced, thereby losing the filtering effect, and the normal use can be recovered only by frequently replacing the quartz sand. In summary, the main disadvantages of the conventional sand cylinder filter are as follows: the dirt on the sand layer can not be discharged by back flushing, the filtering and purifying effect is influenced, and a large amount of clear water is wasted; the frequent times of replacing the quartz sand are increased, and labor, time and materials are wasted.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a water-saving fast clean sand jar filter of air supporting recoil to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a water-saving fast clean sand jar filter of air supporting recoil, includes sand jar filter and water-locator, sand jar filter top sets up the inlet tube, sand jar filter bottom sets up a high-pressure swirl air pump, the water-locator is gone up mouthful through feed mechanism and gas-supply pipe and play water piping connection, the outlet pipe outer end is provided with the outside control mechanism who prevents high-pressure gas leakage sand jar filter.
As a further aspect of the present invention: the communicating mechanism is a three-way pipe, and the upper opening of the water distributor is connected with the gas conveying pipe and the water outlet pipe through the three-way pipe.
As a further aspect of the present invention: the upper end of the gas transmission pipe is provided with a check valve which can prevent water from flowing back into the high-pressure vortex gas pump.
As a further aspect of the present invention: the control mechanism is a valve which can prevent high-pressure gas from leaking out of the sand cylinder filter.
Compared with the prior art, the beneficial effects of the utility model are that: when the sand cylinder filter needs backflushing sewage discharge, a water outlet valve is closed, a high-pressure vortex air pump is opened, high-pressure gas is blown to the upper part of a sand layer through a gas delivery pipe and a water distributor uniformly, so that dirt floats on the sand layer rapidly, then backflushing is performed slightly, the dirt can be gathered into a sewage pipeline through a water inlet pipe and discharged, and the high-pressure gas and water formed after the gas output by the high-pressure vortex air pump is mixed with water in the sand cylinder filter converge body and can blow and impact the dirt in the sand layer strongly, so that the dirt can be blown to float on the sand layer completely, the flushing and the discharging are facilitated, and the effect of loosening a sand layer filter material is achieved.
