Description

Integrated filtering separation pry

Technical Field

The utility model relates to a sewage treatment technical field, concretely relates to integrated filtration separation sled.

Background

With the general promotion of environmental protection consciousness, people put forward higher requirements on the treatment of sewage. How to carry out effectual processing to sewage, can discharge safely after making sewage purification, avoid causing the pollution to the surrounding environment, become the key point that people paid attention to.

In the prior art, the sewage purification is usually carried out by adopting the matching of a filter tank and a filter press, the sludge in the filter tank is discharged to a sludge tank, and the filter press pumps the sludge from the sludge tank for filter pressing. The water inlet of sewage sets up on filtering the jar wall of jar, and sewage lets in jar body back, and the uniform velocity of following cylindric jar body is rotatory earlier, sinks to the whirl bucket with jar body coupling again, and under the effect of vortex field, the large particle size suspended particles in the sewage sinks (collects and forms mud) along the whirl bucket separation, and the sewage rises and passes through the filter layer after discharging.

The disadvantage of this method of purification of sewage is that the large-particle-size suspended particles to be separated form a large interference with the rising sewage. If the sewage flow rate is too large, on the one hand: sewage is not fully filtered and quickly penetrates through the filter layer to be discharged; on the other hand, the large suspended particles separated and thrown to the tank wall in the ascending process are driven upwards again by newly introduced sewage, so that the quality of the purified water does not reach the standard. If the sewage flow speed is too small, the sewage lifting force is insufficient, and part of sewage flows to the sludge tank along the cyclone barrel, so that the sludge water content is too large, and the filter pressing workload and the treatment cost of the sludge are increased.

SUMMERY OF THE UTILITY MODEL

Furthermore, a sludge concentration detector is arranged on the sludge collecting hopper.

The integrated filtering separation pry of the utility model separates the tapered cyclone barrel from the tank body, so that an annular gap is formed between the tank body and the cyclone barrel; on one hand, the flowing section of the sewage introduced into the conical rotational flow barrel is smaller and smaller, the newly flowed-in outer layer sewage shrinks and presses the inner layer sewage, the sewage is pressed to spirally go upwards, and the large-particle-size suspended matters are forced to separate from the sewage to spirally sink due to slow speed change, namely, the large-particle-size suspended matters are quickly separated from the sewage through the 'abrupt change' of the flow speed of the sewage; on the other hand, in the rising process after the sewage is separated from the cyclone barrel, part of large-particle-size suspended matters which are not separated in the barrel are thrown to the wall of the tank under the action of centrifugal force and then flow into the mud collecting hopper along the annular gap between the tank body and the cyclone barrel, so that the large-particle-size suspended matters are fully separated, and the water quality of the purified water is ensured to be up to the standard reliably.

The utility model discloses still hinder and revolve the board through setting up on the mud collection fill, to mud that the mud collection fill top converges the flow down disperse the buffering, reduce its velocity of flow, reduce the disturbance to mud in the mud collection fill, and then reduce bubble content in the mud collection fill, be favorable to improving pressure filter efficiency. Additionally, the utility model discloses intensive filtering mechanism and the pressure filter that sets up has saved the construction of traditional mud ground, and equipment fixing is quick and economy, still practices thrift the land used simultaneously, arranges beautifully.
