An unpowered-filtering sewage cleaning device includes a sewage discharge mechanism, a water conveyance mechanism, a filtration mechanism, a water guidance mechanism, a water discharge mechanism, a support mechanism, and a transmission mechanism. The transmission mechanism includes a main transmission shaft, a clutch mechanism, and an auxiliary transmission shaft. The main transmission shaft is mounted with the auxiliary transmission shaft through the clutch mechanism. In case of disengagement of the clutch mechanism, the main transmission shaft rotates, while the auxiliary transmission shaft does not rotate. In case of engagement of the clutch mechanism under a pressure, the main transmission shaft drives the auxiliary transmission shaft to rotate coaxially. The water conveyance mechanism, the filtration mechanism, and the water guidance mechanism are mounted with the main transmission shaft. The sewage discharge mechanism is mounted with the auxiliary transmission shaft. The unpowered-filtering sewage cleaning device has a simple structure.

A system and method for the pyrolysis of a pyrolysis feedstock utilizes a pyrolysis reactor having a pyrolysis conduit and a solids return conduit segment. Each segment is configured with an outlet and an inlet to receive and discharge solid materials that are circulated through the reactor through the different segments. A solids conveyor is disposed within the pyrolysis conduit segment to facilitate conveying solid materials from the solids inlet upward through the pyrolysis conduit segment toward the solids discharge outlet. A pyrolysis feedstock is introduced into the pyrolysis reactor and at least a portion of the feedstock is converted to pyrolysis gases within the pyrolysis conduit segment, which are discharged through a gas outlet. An eductor condenser unit with an eductor assembly having a venturi-restricted flow path for receives a pressurized coolant fluid. A second flow path for receiving the discharged pyrolysis gases intersects the venturi-restricted flow path so that the received pyrolysis gases are combined with the coolant fluid and are discharged together to a mixing chamber that is used to condense pyrolysis gases.

An inlet sieve for a self-priming floating pump features a bottom wall that is carried in a position that underlies the inlet of the self-priming floating pump at a distance therebelow with the inlet of the pump aligned with an axis that passes through the bottom wall of the sieve. A perforated outer wall of the sieve stands upward from a top side of the bottom wall and extends about the axis. The bottom wall features an outer area that spans inwardly from the perforated outer wall toward the axis, and a protuberance that bulges upwardly from the outer area to an apex of the protuberance that is situated at the axis. Water flowing inwardly toward the protuberance from different radial directions is directed smoothly upward into the inlet of the pump with minimal turbulence in order to optimize the performance of the pump.

A device for concentrating an object to be treated has a filter body in which a movable plate is disposed between adjacent annular fixed plates, the moveable plate being formed in the same annular shape. Sludge filtrate passes through filtrate inflow gaps between the fixed plates and the movable plate before being caused to flow into the filter body. The movable plate is moved so that solids in the sludge are kept from clogging the filtrate inflow gaps. A cleaning member is caused to rub against the outer peripheral surfaces of the fixed plates so that solids adhering to the outer peripheral surfaces of the fixed plates are scraped off. The movable plates of said device are caused to perform a circular movement by eccentric cams fixed to the shaft. The cleaning member is fixed to the shaft, and caused to rotate around the shaft by the rotation of the shaft so that solids adhering to the outer peripheral surfaces of the fixed plates are scraped off.

A dewatering device for aggregate product can be used to retro-fit existing aggregate product dewatering facilities in order to more efficiently capture product. The dewatering device can be movable to allow for the portability of the device relative to existing dewatering facilities. The device is adapted to receive a slurry of aggregate product and water and to vibrate to dry the aggregate product. A recycle system is included to receive any fines that may otherwise be lost by the system. The recycle system captures the fines and redirects them back towards the vibrating process of the vibrating device to direct them towards an exit of the vibrating device in order to use said fines as well as the other dewatered aggregate product. The portability of the device allows the device to be used with the existing facilities without the need to completely replace existing components for dewatering aggregate product.

A filtering device includes a pleated filter that includes a filter base having folds that repeatedly form mountains and valleys and having a cylindrical shape whose direction of an axis is a ridge line direction of the folds and in which the mountains are located outward in a radial direction, an untreated-water nozzle through which untreated water is ejected toward an outer circumferential surface of the pleated filter, a case that includes an outer tubular portion provided so as to surround the pleated filter and including a nozzle opening of the untreated-water nozzle therein, a filtered-water flow path that leads filtered water having passed through the pleated filter from the inside of the cylinder of the pleated filter to the outside of the case, and a discharge flow path through which discharge water that is not filtered by the pleated filter is discharged to the outside of the case. The pleated filter is configured to rotate in a direction about the axis. Ridge lines of the plural mountains of the pleated filter are curved in a shape that expands in a direction opposite to the rotation direction.
