[0001] The utility model relates to an anti-blocking mechanism, in particular to an anti-blocking mechanism for sludge of a spiral filter press Background Technique
[0002] The spiral filter press for sludge dewatering is a water treatment device widely used in municipal sewage treatment projects and industrial sectors such as petrochemical, light industry, chemical fiber, paper making, pharmaceutical, and leather industries. The spiral filter press for sludge dewatering can dewater sewage in the form of flocculated condensates, reducing impurities in the sewage during discharge. 1. When discharging sludge, some sludge is likely to adhere to the surface of the sludge plate and accumulate, making it inconvenient for workers to clean, resulting in long-term sludge accumulation and affecting subsequent sludge discharge. 2. It does not have the function of dispersing larger flocculated condensates, so when the sludge pump pumps sewage, it is easily blocked by larger flocculated condensates and cannot be used.
[0003] When the spiral filter press is in use, foreign matters in the sludge may block the filter screen of the spiral filter press, affecting the filtering use of the spiral filter press and being unfavorable for the use of the spiral filter press. Content of the Utility Model
[0004] In view of the above situation, to overcome the defects of the prior art, the utility model provides an anti-blocking mechanism for sludge of a spiral filter press, effectively solving the problem that when the spiral filter press is in use, foreign matters in the sludge may block the filter screen of the spiral filter press, affecting the filtering use of the spiral filter press and being unfavorable for the use of the spiral filter press.
