Description

Technical Field

[0001] The utility model relates to the technical field of sludge discharge equipment in water plants, in particular to a siphon bridge with a sludge scraper and a sludge concentration detector. Background Art

[0002] When a water plant is treating water, it is necessary to discharge the sludge and impurities precipitated during the water treatment process in the sedimentation tank. The most widely used existing technology is to use a movable siphon bridge on the sedimentation tank to discharge the sludge. Usually, the siphon bridge is equipped with a scraper and a suction pipe that penetrates into the sedimentation tank. When the siphon bridge moves, the sludge is scraped up and then sucked away through the suction pipe to achieve sludge discharge. The existing siphon bridge is provided with multiple suction pipes with only separate suction ports under the siphon bridge to suck the sludge, which will result in uneven sludge suction. When scraping the sludge with the scraper, the suction cannot be stopped or stopped according to the sludge concentration. Both high-concentration and low-concentration sludge are sucked away. The amount of water pumped is large. For example, if 500 cubic meters are discharged per hour, a large number of storage tanks are required to collect the water, which will lead to waste of resources and increase production costs.

[0023] A siphon bridge with a scraper and a sludge concentration detector, see Figure 1-3, including a bridge body 100 arranged above the sedimentation tank. The utility model is used for a water treatment device in a sedimentation tank of a water plant. Generally, the bridge body 100 can be movably arranged on the top of the sedimentation tank. A slide rail is provided on the sedimentation tank. The bridge body 100 is hung on the top of the sedimentation tank through the slide rail and can move back and forth using an installed driving device; the bridge body 100 is provided with a plurality of mud suction pipes 110 extending to the sedimentation tank and a plurality of mud scrapers 120. The mud scrapers 120 are connected to lifting rods 130. The mud scrapers 120 can be turned up and down by the driving of the lifting rods 130. Four siphon ports 111 and a sludge concentration detector 112 are provided at the bottom of the mud suction pipe 110. The bridge body 100 is provided with a siphon vacuum system connected to each mud suction pipe 110; the mud suction pipe 110 can control the mud in the sedimentation tank through the control of the siphon vacuum system The sludge is extracted and discharged, and multiple sludge suction pipes 110 cooperate with multiple siphon ports 111 to increase the adsorbable coverage area and evenly adsorb the sludge in the sedimentation tank; the scraper 120 contacts the bottom of the sedimentation tank after downward movement, and accumulates the sludge to a certain thickness. The sludge concentration detector 112 is a device for measuring the sludge concentration or suspended solids concentration in the sewage treatment process. The sludge concentration detector 112 can measure the suspended solids content in the sewage. When it is detected that the sludge thickness reaches the sludge discharge thickness, the sludge concentration detector 112 sends a sludge discharge signal to the electronic control system provided in the bridge body 100, and the siphon vacuum system automatically operates to enable multiple sludge suction pipes 110 to adsorb and discharge sludge at the same time; the utility model can effectively control the sludge discharge time and sludge discharge amount, and realize the fully automatic integration of the sludge discharge process.

[0024] Furthermore, the bridge body 100 is provided with a plurality of frames 101 extending toward the sedimentation tank, and the number of the frames 101 matches the number of the mud suction pipes 110 and the mud scrapers 120. The frames 101 are used to fix the mud suction pipes 110 and the mud scrapers 120 to provide support or connection thereto; the mud scrapers 120 are provided with a first rotating seat 121, and the bottom end of the lifting rod 130 is connected to the mud scrapers 120 by connecting to the first rotating seat 121.
