Detailed Description

Example 1: take two high density sedimentation tanks as an example

An automatic cleaning device for the inclined plate/pipe accumulated mud of a high-density sedimentation tank is shown in figure 2 and comprises a middle-high pressure small flow pump 1 and two groups of flushing pipelines 2, wherein each group of flushing pipelines consists of a plurality of branch pipes 22 and a main pipe 21, holes are formed in the branch pipes at certain intervals, each branch pipe 22 is respectively connected with the main pipe 21, and the main pipe 21 of each group of flushing pipelines is connected with the flow pump 1; a group of flushing pipelines are arranged above the inclined plates/pipes in a high-density sedimentation tank.

A high-density sedimentation tank sloping plate/pipe accumulated mud automatic cleaning method, take two high-density sedimentation tanks as an example, as shown in figure 6, for two high-density sedimentation tanks 1# and 2#, respectively set up the flushing pipeline above the sloping plate/pipe of the high-density sedimentation tank, the flushing pipeline is made up of several branch pipes and main pipes, the said branch pipe is fixed on the outlet channel 3 above the sloping plate/pipe, there are holes on the branch pipe according to certain interval, each branch pipe is connected with main pipe separately, the main pipe in each high-density sedimentation tank is connected with a bidirectional pump 1; when the No. 2 tank is to be cleaned, the flow pump can be started and controlled to pump water in the No. 1 tank through the branch pipe so as to clean the inclined plate/the flushing of the No. 2 tank; when the No. 1 tank is cleaned, the flow pump can be started and controlled to pump water in the No. 2 tank through the branch pipe to flush the inclined plate of the No. 1 tank.

Specifically, as shown in fig. 3-5, the UPVC pipes 22 of De 25-De 40 are fixed at the bottom of the stainless steel water outlet channel 3 by using hoops, and holes 5 with the aperture of 10-25 are formed on the UPVC pipes 22 every 20-100 cm, and the hole forming direction is consistent with the arrangement direction of the inclined pipes or forms an angle of-45 degrees.

The lower part of the water outlet channel 3 is closer to the inclined plate (pipe) 4, and the resistance is suddenly increased due to the change of the hydraulic flow direction, so that flocs in the inclined plate (pipe) are easier to deposit in the inclined plate (pipe). The swash plate (pipe) fouling occurring in actual production operation also occurs mainly in this area. Therefore, high-pressure water is injected into the UPVC pipe with the opening direction parallel to the inclined plate (pipe) or the optimal angle, and forms circulation with partial water flow without high-pressure water, so that the dirt blockage is relieved, and the aim of automatically cleaning the inclined plate (pipe) is fulfilled.
