Problems solved by technology

However, the existing sewage sedimentation tanks are often equipped with other facilities, such as bridges for walking, etc., which hinder the installation of this vertical mud scraper. Therefore, they cannot be well applied to the current sewage sedimentation tanks. Moreover, this kind of vertical sludge scraper will affect the sludge settlement, and the equipment is larger in size, takes up a lot of space, and has higher input costs

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] like Figure 1 ~ Figure 4 As shown, the mud scraper used in the sewage sedimentation tank includes a track 2 arranged at the bottom of the pool 11, a frame 3 that can walk freely on the track 2, four wheels 4 located under the frame 3, and a Link mechanism 5, mud scraper 6 and a rope 7 on the vehicle frame 3;

[0034] Wherein, the vehicle frame 3 is a rectangular frame with an outer periphery, and a weight block 31 is respectively arranged on the top of its four corners, so that the mud scraper can walk more smoothly at the bottom 11 of the pool, and the bottom of the vehicle frame 3 is located on the four sides. Each corner is provided with a support plate 32, and each wheel 4 is rotatably positioned on the outside of the corresponding support plate 32 through the wheel shaft 41 passing through the corresponding support plate 32, that...

Abstract

The invention discloses a mud scrapper applicable to a detention pool, comprising a track (2), a frame (3), wheels (4), a connecting rod mechanism (5) on the frame (3) and a rope (7); wherein each wheel (4) is rotatablely positioned at one side of a corresponding supporting plate (32) by an axle (41); the connecting rod mechanism (5) comprises at least two driven pulling rods (53) that pass through and are arranged at corresponding axles (41) respectively, at least two connecting plates (52) connecting a front and a rear driven pulling rods (53) and a driving pulling rod (51), in addition, the driving pulling rod (51) is pulled by the rope (7), the rope (7) parallels to the track (2), while the mud scrapper (6) is arranged at the bottom of the driven pulling rods (53). Compared with the prior art, in the invention the rope pulls the connecting mechanism and drives the mud scrapper arranged on the connecting mechanism to touch the bottom of the pool body, meanwhile, by the pulling of the rope, the frame can walk along the track, therefore, the mud scrapper can continuously scrap and collect the mud-like deposits at the bottom of the pool body.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a mud scraper for scraping muddy sediments at the bottom of a sewage sedimentation tank. Background technique [0002] At present, most of the mud scrapers used in sewage sedimentation tanks use chain mud scrapers to move the muddy sediment deposited on the bottom of the tank. However, the core components of this chain mud scraper and chains, etc. , is susceptible to serious corrosion by sewage. In the actual application process, the mud scraper often has serious failures, and the maintenance workload is heavy, which brings a lot of inconvenience to the use. [0003] Also have a kind of vertical mud scraper in addition, it is to arrange movable crossbeam on the water surface of sewage sedimentation tank, and vertically rising mud scraper is installed on the crossbeam arm. However, the existing sewage sedimentation tanks are often equipped with other facilities, such as ...
