摘要： PROBLEM TO BE SOLVED: To provide a sludge collector for a sedimentation basin the thickness of which can be reduced and the components of which can be made lighter by improving wear resistance, preventing the elution of an endocrine disturbing matter and improving corrosion resistance ever when the collector is used in the final sedimentation basin in which anaerobic bacteria such as sulfate reducing bacteria has propagated. SOLUTION: The sludge collector for sedimentation basin is provided with a head sprocket wheel pivotally supported in the sedimentation basin in a freely rotatable manner, a tail sprocket wheel, endless chains put around the respective sprocket wheels in parallel and a flight fitted to the parallel endless chains. The collector rotates the endless chains to move the flight to collect the sludge deposited in the sedimentation basin in a prescribed direction. At least a part of the components consist of austenitic stainless steel.

摘要： PURPOSE:To eliminate the need for a worker and to prevent generation of overload in a turning device by performing elevating/lowering control so that the height of a scraping-up face is lowered until driving torque is raised larger than an intermediate torque level when a state wherein the driving torque is lowered smaller than a low torque level is continued for a specified time. CONSTITUTION:Driving torque of a turning device 6 is detected by a torque detector 7 and gradually lowered according to scraping-up of settled grit 31 by a bucket 2. When a state wherein driving torque is lower than a low torque level is continued for a specified time, an elevating/lowering controlling device 25 outputs a command signal of lowering to an elevating/lowering device 21. Therefore the height of a scraping-up face 3 is gradually lowered and the bucket 2 gradually bites into the settled grit 31 and driving torque is gradually raised. When the bucket 2 bites into grit 31 and driving torque is raised larger than an intermediate torque level, the controlling device 25 releases the command signal of lowering. Therefore, the elevating/lowering device 21 is stopped in this state and the driving torque of the turning device 6 is gradually lowered according to scraping up of settled grit 31. Thereafter this is automatically repeated.

摘要： PURPOSE:To automatically remove foreign materials, by arranging a plurality of autoscreens equipped with a plurality of rakes at the upper stream of a screen and connecting a water trough thereto and further, by operating a breaker and a jet pump at the downstream end. CONSTITUTION:A screen 10 is arranged in a water way 1 and a plurality of foreign materials-removers 2 equipped with rakes 15 are arranged in the upper stream thereof. And these are connected to water troughs 3 respectively and further, a breaker 4 and a jet pump 5 are arranged in the downstream of the water troughs 3. The foreign materials collected by the screen 10 in this arrangement are raised up by the rake 15 and washed down in the water trough 3 with the ejected water from ejection nozzles 16. Next, the foreign materials collected by the auto-screen are pulverized by the breaker 4 and sucked by the jet pump 5. In this way, it is easy to maintain it and foreign materials are discharged by the jet pump and hence, mechanical troubles can be decreased.

摘要： PURPOSE: To provide a titled device which is easy to maintain, by providing a function to follow up the fluctuation in the amt. of the settled sand and taking up automatically a chain to avoid the operational failure due to overloading when the amt. of the settled sand increases suddenly.
CONSTITUTION: A chain 18 is turned in an arrow E direction while a chain wheel 6 in the submerged head part and a chain wheel 11 in the submerged tail part are held pressed to the bottom side of a sand basin by the present own weight of a link, etc. applied to levers 3 and 10. Buckets 17 scrape the sand settled on the bottom of the sand basin toward the wheel 6 side and take the sand therein when the buckets pass the wheel 6 and go to an intermediate chain wheel 12 in the upper part. When the buckets pass the wheel 12, the attitude thereof is faced downward to drop the sand onto a discharging chute 16. This sand scraper oscillates freely and universally the levers according to the load in the stage of scraping the top surface of the sand irrespectively of the amt. of the settled sand and is operated always under specified chain tension without any operation at all from the outside.
