Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for municipal engineering. Background Technology

[0002] In the field of municipal engineering, wastewater needs to be purified to remove particulate impurities. However, existing wastewater treatment equipment on the market cannot thoroughly purify wastewater from municipal engineering projects. The treated wastewater still contains particulate matter residue, resulting in unsatisfactory treatment effects and environmental friendliness, failing to meet the needs of municipal engineering wastewater treatment.

[0003] Patent CN113415921A discloses a sewage treatment device for municipal engineering, including a tank. An electric motor is mounted on the upper end of the tank, with its output shaft extending into the tank and connected to a stirring paddle. An outlet is installed at the lower end of the tank, and an inlet is installed on the upper end of the tank's side wall. One end of a first connecting pipe is connected to the lower end of the tank, and the other end of the first connecting pipe is connected to the side wall of a filter tank. A water pump is installed on the first connecting pipe, and a sludge outlet is installed at the bottom of the filter tank. This invention involves adding sewage and flocculant into the tank and stirring. After stirring, the water pump drives the sewage to circulate between the filter tank and the tank. During the sewage flow, impurities are adsorbed by filter balls, achieving water purification. However, it has the problem of difficulty in separating and filtering large objects such as leaves and branches, which can easily damage the device. Therefore, this invention proposes a sewage treatment device for municipal engineering to solve the aforementioned problems. Summary of the Invention

The circumferential surface of the sliding plate 402 is slidably connected to the inner wall of the tank body 1. Working principle: The motor drives the threaded rod 401 to rotate, which in turn drives the sliding plate 402 to move to the right.

[0016] Working principle: The threaded rod 401 drives the rotating column 605 to rotate, which in turn drives the rotating ring 602 to rotate. The rotating ring 602 then drives the rotating rod 604 to move, which in turn drives the large gear 606 to move.

The rotating ring 602 rotates, causing the support block 801 to move. The movement of the support block 801 causes the reciprocating screw 803 to move, which in turn causes the pinion 804 to move. Simultaneously, the rack ring 601 drives the pinion 804 to rotate, which in turn drives the reciprocating screw 803 to rotate. The reciprocating screw 803 drives the scraper 802 to move back and forth, cleaning impurities from the inner wall of the tank 1 and ensuring its cleanliness. The movement of the scraper 802 causes the crushing column 901 to move. The crushing column 901 contacts the inner wall of the tank 1 and begins to rotate. The rotation of the crushing column 901 drives the support column 902 to rotate, which in turn drives the linkage gear 904 to rotate. The linkage gear 904 drives the rack 903 to move, allowing the rack 903 to enter the groove 905 to prevent it from being blocked by sediment, thus preparing it for subsequent removal and ensuring its complete removal.
