Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand filtering devices, and more specifically, to a low-pressure micro-resistance quartz sand filtering device. Background Art

[0002] The quartz sand filter is a device widely used in wastewater treatment. It uses quartz sand as a filter medium and filters water with high turbidity through a quartz sand layer of a certain thickness under a certain pressure, effectively removing suspended matter, organic matter and some heavy metal ions in the water, thereby achieving the effect of reducing water turbidity and purifying water quality. However, there are some problems with the existing quartz sand filter: usually, the wastewater to be treated is poured on the top of the quartz sand and discharged after being filtered through the quartz sand layer. However, with long-term use, a large amount of particulate impurities will accumulate in the gaps of the quartz sand layer, resulting in obstruction of wastewater flow, reducing the filtration flow, and failing to achieve a water purification effect. However, since the partition that fixes the quartz sand layer is difficult to disassemble, the efficiency is low when the quartz sand layer needs to be replaced, which reduces the practicality of the equipment.

[0032] The water inlet assembly 6 includes a liquid pump 60, a water inlet pipe 61, a connecting pipe 62, a double-ended connecting pipe 63, and a water outlet pipe 64. The bottom of the liquid pump 60 is fixedly installed on the top of the bottom plate 1, the side end of the water inlet pipe 61 is fixedly installed on the side of the liquid pump 60, the bottom end of the connecting pipe 62 is fixedly installed on the top of the liquid pump 60, the middle part of the double-ended connecting pipe 63 is fixedly installed on the side end of the connecting pipe 62, the end of the double-ended connecting pipe 63 is fixedly installed on the outer surface of the filter device body 3, and the side end of the water outlet pipe 64 is fixedly installed on the outer surface of the filter device body 3;

[0033] By setting up a double-ended connecting pipe 63 and controlling the opening of a valve 65 at the end of the double-ended connecting pipe 63, the staff can discharge the waste water through the top end of the double-ended connecting pipe 63 into the interior of the filter device body 3 for filtering treatment, and the staff can also discharge clean water through the bottom end of the double-ended connecting pipe 63 into the interior of the filter device body 3 to backwash the quartz sand layer medium set on the top of the lower filter partition 80, thereby improving the practicality of the device.

[0034] The water inlet assembly 6 further includes a valve 65 , and four valves 65 are provided. The valves 65 are respectively arranged at the ends of the connecting pipe 62 , the double-headed connecting pipe 63 , and the water outlet pipe 64 .

[0037] The working process of the utility model is as follows:

[0038] First, the wastewater to be treated is connected to the water inlet pipe 61, and the valve 65 set at the side end of the connecting pipe 62 and the top of the double-ended connecting pipe 63 is opened, and then the liquid pump 60 is started, and the wastewater enters the connecting pipe 62 along the water inlet pipe 61, and then enters the interior of the filter device body 3 along the top of the connecting pipe 62 and the double-ended connecting pipe 63, and flows downward from the top of the upper filter partition 82 to the lower filter partition 80. After passing through the quartz sand layer set between the lower filter partition 80 and the upper filter partition 82, the wastewater is filtered and reaches the bottom of the filter device body 3. Finally, the staff opens the valve 65 at the end of the water outlet pipe 64 to discharge the filtered clean water;

[0039] In the process of filtering wastewater, the electric cylinder 71 can be started to control the electric cylinder 71 to contract, driving the airtight piston 72 to move upward along the inside of the sleeve 70, so as to extract the air inside the filter device body 3, so that the air pressure inside the filter device body 3 is reduced, thereby increasing the time for water to pass through the quartz sand layer medium, so that the water can contact the medium more fully, thereby achieving a better filtering effect;
