Description

Technical Field

[0001] This utility model relates to the field of hydrolysis acidification wastewater treatment technology, and in particular to a novel sludge anti-clogging system for hydrolysis acidification tanks. Background Technology

[0002] In the field of hydrolysis acidification wastewater treatment technology, the hydrolysis acidification tank is a crucial treatment unit, and its operational performance directly affects the efficiency and quality of the entire wastewater treatment process. However, sludge treatment has always been a challenging issue in actual operation.

[0003] As wastewater treatment progresses, a large amount of sludge gradually accumulates at the bottom of the biological micro-electrolysis reactor. Traditional sludge discharge systems often lack effective anti-clogging measures, and the sludge easily clumps and blocks the discharge pipes or holes, leading to poor sludge discharge. Once sludge discharge is obstructed, the accumulation of sludge in the reactor becomes increasingly severe, not only occupying a large amount of reaction space but also affecting the hydraulic conditions within the reactor, resulting in uneven mixing and reaction of wastewater and sludge, and reducing the efficiency of the hydrolysis and acidification reaction. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a novel sludge anti-clogging system for hydrolysis acidification tanks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel sludge anti-clogging system for hydrolysis acidification tanks includes a biological micro-electrolysis reactor. An inlet pipe is provided on one side of the biological micro-electrolysis reactor near the bottom, and an outlet pipe is provided on the side of the biological micro-electrolysis reactor away from the inlet pipe near the top. A sludge discharge system is provided inside the biological micro-electrolysis reactor.

[0007] The sludge removal system includes multiple sludge collection grooves installed on the bottom inner wall of the biological micro-electrolysis reactor. Sludge removal branch pipes are rotatably installed in the sludge collection grooves, and the sludge removal branch pipes are equipped with multiple blades and sludge removal holes.

[0008] Preferably, one end of the water inlet pipe extending into the biological micro-electrolysis reactor is connected to an annular water distribution pipe, and the annular water distribution pipe has multiple water distribution holes.

[0009] Preferably, one end of the sludge discharge branch pipe extends to the outside of the biological micro-electrolysis reactor, and a sludge discharge main pipe is fixed to the outside of the biological micro-electrolysis reactor near the bottom. The sludge discharge branch pipe and the sludge discharge main pipe are connected by a second rotary joint, and adjacent sludge discharge branch pipes are synchronously driven by belts and powered by a first rotary motor.

[0010] Preferably, the biological micro-electrolysis reaction tank is equipped with a scraper, the bottom end of which contacts the inner wall of the biological micro-electrolysis reaction tank, and connecting rods are fixed on both sides of the top end of the scraper, with the top end of the connecting rods extending to the outside of the biological micro-electrolysis reaction tank.

[0011] Preferably, a horizontal moving bar is fixed between the top ends of the two connecting rods, and a second guide rod is fixed at the top end of the bio-microelectrolysis reaction cell, the second guide rod moving through the horizontal moving bar.

[0012] Preferably, a threaded rod is rotatably mounted on the top of the biological micro-electrolysis reactor. The threaded rod is driven to rotate by a second rotary motor, and the threaded rod passes through a threaded hole through a horizontal moving bar.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The sludge collection ditch in the sludge discharge system works in conjunction with the rotating sludge discharge branch pipe. The blades installed on the sludge discharge branch pipe can effectively break up any sludge that may clump during rotation, preventing sludge from accumulating at the bottom of the biological micro-electrolysis reactor and clogging the sludge discharge holes. This ensures the smooth progress of the sludge discharge process, maintains a good working environment in the reactor, and is conducive to the continuous and stable hydrolysis and acidification reaction, thereby improving the operating efficiency and reliability of the entire wastewater treatment system.

[0015] 2. The inlet pipe extends into the annular water distribution pipe connected inside the biological micro-electrolysis reactor, and the annular water distribution pipe has multiple water distribution holes, which can make the wastewater entering the reactor evenly distributed, avoiding problems such as uneven sludge distribution and local deposition caused by excessive local water flow impact or uneven water distribution. This is conducive to improving the reaction effect in the reactor, allowing the hydrolysis acidification reaction to proceed more fully, and improving the wastewater treatment quality.

[0016] 3. The scraper installed inside the biological micro-electrolysis reactor is connected to a horizontally moving bar outside the reactor via a connecting rod. Driven by a second rotary motor, the threaded rod rotates, and guided by a second guide rod, enabling the scraper to move horizontally. The scraper effectively removes accumulated sludge from the bottom of the biological micro-electrolysis reactor, scraping the sludge into the sludge collection ditch. This further improves sludge discharge efficiency, reduces sludge residue at the bottom of the reactor, lowers the risk of sludge blockage, ensures long-term stable operation of the reactor, reduces equipment maintenance and cleaning work caused by sludge problems, and lowers operating costs.

A sludge discharge branch pipe 502 is rotatably installed within each sludge collection channel 501. The sludge discharge branch pipe 502 is equipped with multiple blades 5021 and sludge discharge holes 5022. One end of the inlet pipe 101 extending into the biological micro-electrolysis reactor 1 is connected to an annular water distribution pipe 1011, which has multiple water distribution holes to achieve uniform water distribution.

[0029] The first rotary motor 505 can drive multiple sludge discharge branch pipes 502 to rotate synchronously. The blades 5021 can stir and break up the sludge accumulated at the bottom of the biological micro-electrolysis reactor 1, so as to prevent the sludge from clumping and blocking the sludge discharge hole 5022, and ensure that the sludge can be discharged more smoothly. The cleaning liquid can be introduced into the biological micro-electrolysis reactor 1 through the sludge discharge main pipe 503 for backwashing.

The threaded rod 705 is driven to rotate by the second rotary motor 704, and the threaded rod 705 passes through the horizontal moving bar 702 through the threaded hole.

[0032] When the second rotary motor 704 is turned on, it can drive the threaded rod 705 to rotate. With the guidance of the second guide rod 703, it can drive the horizontal moving bar 702 to move horizontally, and then drive the scraper 7 to move horizontally, thereby cleaning the sludge accumulated at the bottom of the biological micro-electrolysis reactor 1. The sludge can be scraped into the sludge collection ditch 501, which can improve the sludge discharge efficiency and effect.
