[0003] In view of the above problems, the prior art urgently needs a flushing device that can effectively clean the discharge pipe while reducing pipe wall scouring and prolonging the service life.Despite the existence of some improved flushing solutions in the market, these solutions either have complex structure and high cost, or have limited flushing effect, and cannot fundamentally solve the problem of damage to the pipe wall caused by backflushing water flow.Therefore, the utility model provides an innovative ceramic filter discharge pipe flushing device, which aims to redesign the structure of the backflushing water pipe to ensure that the backflushing water flow can fully and effectively flush the discharge pipe, and by changing the direction of the water flow, the direct scouring effect of the backflushing water on the pipe wall is significantly reduced, thereby effectively prolonging the service life of the discharge pipe, reducing the production cost caused by frequent replacement of the discharge pipe, and reducing the increase of labor cost caused by downtime maintenance, which provides strong protection for the efficient and stable operation of the ceramic filter.

[0022] The features and performance of the utility model will be further described in detail in connection with examples.

[0023] As Figure 1 The installation method of the utility model is as follows:

[0024] Installation method: S1: first measure size and make backflushing elbow 22 well;

[0025] S2: the original backflush water pipe 21 is cut off and polished, and a backflush water elbow 22 is welded;

[0026] S3: the start of the backflush water device 2 is interlocked with the start of the ceramic filter discharge valve 32, when the utility model is started, the air bag valve on the discharge valve 32 is opened, that is, the control medium is drawn out of the rubber pipe sleeve of the air bag valve, the rubber pipe sleeve is stretched outwardly under the fluid pressure, the discharge valve 32 is opened, and since the pipe sleeve has a reinforcing cord layer, the length and diameter of the pipe sleeve will not change due to the fluid pressure. When the ceramic filter discharges, the backflush water valve 23 is also opened, and when the ceramic filter stops discharging, the backflush water device 2 also stops, which can dilute the ore pulp, prevent clogging, and quickly discharge.
