Waste acid water multi-purification filtering device capable of quickly replacing filter

Abstract

The invention discloses a waste acid water multi-purification filtering device capable of rapidly replacing a filter, and relates to the technical field of sewage filtering equipment. The device comprises a filter tank, first supporting legs and a filter plate, the first supporting legs are fixed to the four corners of the lower side wall of the filter tank respectively, the filter plate is arranged in the filter tank, an outer frame of the filter plate is arranged on a supporting plate, and the supporting plate is fixed to the inner side wall of the filter tank; the device further comprises aconnecting mechanism, a filter and a purifying mechanism, a water suction pump in the connecting mechanism is fixed to one side wall of the filter tank, the filter is arranged on the right side of the connecting mechanism, and the right side of the filter is connected with a purifying box in the purifying mechanism through a hose; and the filter tank is connected with the filter through the connecting mechanism. The filter is replaced by adjusting two one-way valves, and the whole filtering process does not need to be stopped in the filter replacing process, so that the filtering efficiency is improved; and the device has the advantages of being reasonable in arrangement, low in manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of sewage filtering equipment, in particular to a waste acid water multiple purification filtering device capable of rapidly replacing filters. Background technique [0002] At present, the waste water produced in the production process of the pharmaceutical industry and the fuel industry is waste acid water that generally contains acidic substances. If it is directly discharged into the river, it will seriously pollute the environment and cause great harm to the human body. Therefore, it is necessary to The waste acid water is treated with high-quality waste liquid up to the standard. Therefore, it is necessary to use multiple purification filter devices to filter the waste acid water so that the waste acid water reaches the standard. After the filter device has filtered the waste acid water for a period of time, the filter needs to be However, the filter of the filter device in the prior art is directly co...

[0002] At present, the waste water produced in the production process of the pharmaceutical industry and the fuel industry is waste acid water that generally contains acidic substances. If it is directly discharged into the river, it will seriously pollute the environment and cause great harm to the human body. Therefore, it is necessary to The waste acid water is treated with high-quality waste liquid up to the standard. Therefore, it is necessary to use multiple purification filter devices to filter the waste acid water so that the waste acid water reaches the standard. After the filter device has filtered the waste acid water for a period of time, the filter needs to be However, the filter of the filter device in the prior art is directly connected to the transmission mechanism on the front side of the waste acid water through a hose. When the filter needs to be replaced, the entire filtration process needs to be closed, which reduces the filtration efficiency and needs to be improved urgently.
