Sludge filtering equipment for underground water

Abstract

The invention relates to sludge filtering equipment for underground water. The equipment comprises a filtering belt connected with a feeding hole, the filtering belt is in transmission connection with a driving wheel and is connected with a cloth washing device and a deviation rectifying wheel along the moving direction of the filtering belt, the bottom end of the filtering belt is arranged on a vacuum disc connected with a vacuum tank, and the vacuum tank is connected with the vacuum disc through a switching valve. A reciprocating air cylinder is fixedly installed on one side of the bottom end of the vacuum disc through a connecting rod, a vacuum layer is formed between the filtering belt and a filter medium, a discharging opening formed outside the driving wheel is connected to the extending position of one end of the filtering belt, a tensioning wheel connected with the filtering belt is arranged between the cloth washing device and the deviation rectifying wheel, and carrier rollers matched with the deviation rectifying wheel and the tensioning wheel are connected to the deviation rectifying wheel and the tensioning wheel. The cloth washing device comprises a roller connected with the filtering belt arranged at the corner in a V shape, and a spray pipe arranged in a collecting box is arranged below the roller. The sludge filtering equipment has the beneficial effects that purification is sufficient, the filtering belt cleaning function is achieved, resource waste is prevented, and personnel operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of underground sewage treatment devices, in particular to equipment for filtering groundwater sludge. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or for reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc., and it is also increasingly entering the daily life of ordinary people. , Infiltration wells, infiltration ponds and karst channels, etc., directly discharge industrial wastewater and sewage underground. This way of sewage discharge will cause point-to-point and direct pollution to groundwater. Once polluted, the interaction process among pollutants, water and media is complex. Even if the cost of pollution control can be afforded economicall...

This way of sewage discharge will cause point-to-point and direct pollution to groundwater

Once polluted, the interaction process between pollutants, water and media is complex

Even if the cost of pollution control can be afforded economically, it will take more than ten years, decades or even hundreds of years to remove pollution sources. From this, it can be seen how harmful the environment is if underground sewage is not properly purified. The existing groundwater The functionality of sludge treatment equipment is relatively single, and it cannot perform multiple processes such as filtration, washing, and drying, and the particulate impurities in the sludge cannot be completely removed. Secondly, the filter belt will also reduce the cleaning effect after repeated use , is not conducive to the improvement of purification efficiency and the beautification of environmental quality
