Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0029] In related technologies, sewage treatment sludge removal devices can effectively remove sludge from inside sewage tanks, but the sludge removal effect is poor, the structure is relatively complex, and dead corners exist, affecting the efficiency of sludge removal.

[0030] To address some of the problems in the related technologies, this application provides a sludge removal device. When sludge needs to be removed from the inside of the sewage tank 11, simply start the motor 151 to move the movable plate 14 outside the toothed plate 13, thereby moving the scraper 19 to push the sludge at the bottom of the inside of the sewage tank 11 into the sludge removal mechanisms 12 on both sides. The sludge is then transported out through the auger inside the sludge removal mechanism 12. Then, the motor 151 is reversed, which drives the scraper 19 to move in the opposite direction, pushing the sludge into the sludge removal mechanism 12 on the other side. This device has a simple structure, and the back-and-forth movement of the scraper 19 facilitates the removal of sludge from the bottom of the inside of the sewage tank 11, making it more convenient to use and increasing operational efficiency.

[0031] This application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figs. 1-3 This application provides a sludge discharge device, including a sludge discharge assembly 1. The sludge discharge assembly 1 includes: a sewage tank 11 with a sludge discharge mechanism 12 symmetrically arranged at its bottom; a toothed plate 13 disposed at the top of the sewage tank 11; a movable plate 14 disposed on the outer side of the toothed plate 13; a through groove 141 opened on the movable plate 14; a mounting groove 15 opened on the inner side of the movable plate 14; a motor 151 disposed on the inner side of the mounting groove 15; a gear 152 disposed on the output shaft of the motor 151; a fixed plate 16 symmetrically arranged on the movable plate 14; a movable rod 17 disposed at the top of the fixed plate 16 and passing through the fixed plate 16; a stop block 171 disposed on the outer side of the movable rod 17; a spring 18 sleeved on the outer side of the movable rod 17; and a sludge scraper 19 disposed at the bottom of the movable rod 17.

[0033] When it is necessary to discharge the sludge from the bottom inner side of the sewage tank 11, the motor 151 is first started by connecting an external power source to drive the gear 152 to rotate. Since the gear 152 meshes with the toothed plate 13, the movable plate 14 can be moved outside the toothed plate 13. Since fixed plates 16 are symmetrically arranged on both sides of the movable plate 14, and the movable rod 17 passes through the fixed plates 16 and is connected to the scraper 19, the movement of the movable plate 14 can drive the scraper 19 to move. Since the bottom inner side of the sewage tank 11 is inclined, the scraper can be scraped by pressing down with the spring 18. The mud plate 19 presses against the inner bottom of the sewage tank 11, pushing the sludge at the inner bottom of the sewage tank 11 into the sludge discharge mechanism 12 on both sides. The sludge is then transported out through the auger inside the sludge discharge mechanism 12. This sludge discharge mechanism is common knowledge and will not be described in detail here. Then, the motor 151 reverses, which drives the mud scraper 19 to move in the opposite direction, pushing the sludge into the sludge discharge mechanism 12 on the other side. This device has a simple structure, and the back-and-forth movement of the mud scraper 19 facilitates the discharge of sludge from the inner bottom of the sewage tank 11, making it more convenient to use and increasing work efficiency.

[0034] In some embodiments, an auxiliary component 2 is provided on the toothed plate 13, the auxiliary component 2 including: a rod 21 symmetrically disposed on the top of the toothed plate 13.

[0035] A rod 21 is symmetrically arranged on the top of the toothed plate 13. This rod 21 can limit the movement of the movable plate 14 and prevent the scraper 19 from colliding with the inside of the sewage tank 11 due to operational errors, which would cause damage to the scraper 19.

[0036] In some embodiments, the rod 21 is a screw.

[0037] The rod 21 is configured as a screw and threadedly connected to the toothed plate 13. This allows the rod 21 to be disassembled by screwing and replaced later.

[0038] In some embodiments, the auxiliary component 2 further includes through holes 22 symmetrically formed on the scraper blade 19.

[0039] Multiple sets of through holes 22 are opened on one side of the scraper blade 19. This allows water to pass through the through holes 22 when pushing the sludge, reducing the pressure on the scraper blade 19 and increasing its service life.

[0040] In some embodiments, the auxiliary component 2 further includes pulleys 23 symmetrically arranged inside the through groove 141.

[0041] Pulleys 23 are symmetrically arranged on the inner side of the through groove 141. This allows the pulleys 23 to rotate when the movable plate 14 moves, thereby reducing the friction between the toothed plate 13 and the movable plate 14 and making the movement of the movable plate 14 more stable.

[0042] In some embodiments, the auxiliary component 2 further includes: a slot 24 formed at the bottom of the movable plate 14; and an insert plate 25 disposed at the top of the scraper 19.

[0043] A slot 24 is made at the bottom of the movable plate 14, and an insert plate 25 is set at the top of the scraper 19 and inserted into the inside of the slot 24. This can increase the structural strength of the scraper 19 and increase the service life of the device.

[0044] In some embodiments, the movable rod 17 is connected to the scraper blade 19 by bolts.

[0045] The movable rod 17 and the scraper blade 19 are bolted together, so that the movable rod 17 can be removed and the restriction on the scraper blade 19 can be released, which facilitates the subsequent maintenance or replacement of the parts.

[0046] In some embodiments, the auxiliary component 2 further includes grooves 26 symmetrically formed on the top of the scraper 19.

[0047] Symmetrical grooves 26 are made on the top of the scraper blade 19 so that when the movable rod 17 is installed later, it can be inserted into the inside of the groove 26, which can limit the movable rod 17 so that it can be fixed with bolts later.
