[0002] With the development of cities and the improvement of sewage treatment rate, the sludge production is getting larger and larger. In the existing technology, filter pressing is generally used to separate the solid and liquid of the sludge.

[0003] Currently, Chinese patent publication number CN212687878U discloses a sludge filter press device comprising a support frame, a squeeze mechanism for squeezing, and a vibrator for vibrating. This utility model utilizes a belt-like circulation arrangement of the squeeze mechanism to ensure continuous sludge filtration, while the provision of a scraper ensures the removal of large sludge chunks.

[0004] However, in actual use, although the existing technology can perform continuous filtration operation on the sludge, it can only perform one-time filtration, and the filtration effect is limited. For sludge that is not well treated by filtration, the sludge after one filtration can only be re-filtered. Not only is the operation cumbersome, but the reciprocating operation of the equipment will also increase the filtration cost, which needs to be further optimized.

[0005] Therefore, the present application provides a sludge filter press device to solve the above technical problems. Utility Model Content

For sludge that is not well filtered, the sludge that has been filtered once can only be re-filtered, which is not only cumbersome to operate, but also the reciprocating operation of the equipment will increase the cost of filtration.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0010] Optionally, at least two rotating shafts are provided and are located between the transmission pressure belt and the discharge port.

[0011] Optionally, the mounting brackets at both ends of the rotating shaft correspond to each other one by one, and the rolling cylinder is rotatably mounted between the corresponding two mounting brackets and is parallel to the rotating shaft.

[0012] Optionally, a guide inclined plate is fixed to the bottom of the discharge port, and the top end of the guide inclined plate extends to the lower end surface of the transmission filter belt.

[0013] Optionally, a scraper plate is hingedly mounted on the top upper end surface of the guide inclined plate, a spring connected to the upper end surface of the guide inclined plate is mounted on the lower end surface of the scraper plate, and the top end of the scraper plate abuts against the lower end surface of the transmission filter belt.

[0014] Optionally, a plurality of lower water tanks are provided on the side of the chassis, the lower water tanks extend downward to the bottom of the chassis, and a drainage outlet is provided at the bottom of the chassis.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] At the same time, thanks to the cooperation of the guiding inclined plate, scraper plate and spring, when the transmission filter belt discharges the sludge after filtration from the discharge port, the spring can be used to scrape off some of the sludge adsorbed on the surface of the transmission filter belt, which is not only conducive to ensuring the subsequent filtration efficiency of the transmission filter belt, but also ensures the discharge effect.

[0018] In summary, this device not only has a good filtration effect, can improve the sludge filtration efficiency, reduce the sludge filtration cost, but also has smooth discharge, is conducive to long-term stable operation, and has a good overall use effect. BRIEF DESCRIPTION OF THE DRAWINGS
