6results about How to "With self-cleaning function" patented technology

This invention relates to the field of wastewater treatment technology, and in particular to a microfiltration wastewater treatment device for industrial wastewater turbidity removal. The device includes a treatment cylinder and an L-shaped wastewater pipe installed at the top of the treatment cylinder. A swinging filter assembly is installed at the top inner part of the treatment cylinder. The swinging filter assembly shakes and filters the wastewater. The swinging filter cartridge within the swinging filter assembly swings and moves the filtered impurities. During the swinging process, the swinging filter assembly throws out the wastewater while simultaneously causing the filtered impurities to flow. This invention achieves dynamic separation through swinging filtration, combined with real-time self-cleaning via rotating scraping. The filter cartridge is automatically cleaned by a torsional brush assembly. A fixed filter cartridge with a blocking filter assembly effectively blocks filtration and also possesses a self-cleaning function. This allows for the simultaneous and continuous execution of filtration and cleaning processes, significantly improving wastewater turbidity removal efficiency and the stability and durability of the equipment operation.

The application discloses a dust removal equipment and method for cat litter production workshop, and relates to the technical field of dust removal equipment. The equipment comprises a cylinder, a conical cylinder fixedly connected to the bottom, a ventilation pipe communicated with a bag-type dust collector at the top, and a turbine driven by inlet airflow. Dust-containing air enters the cylinder tangentially to form a spiral airflow. Large-particle dust is centrifugally separated in the conical cylinder and discharged from a dust outlet. The airflow then rises and passes through a filter plate in the ventilation pipe for secondary dust removal. Meanwhile, the turbine drives an arc-shaped scraper to automatically clean the dust accumulated on the filter plate, and the dust is sent back to the pre-dust removal area through a dust collection channel and a dust discharge baffle for recycling treatment. Finally, the clean airflow enters the bag-type dust collector to complete three-stage filtration. The turbine drives the scraper on the movable plate to automatically clean the bag through a transmission shaft and a speed reducer. The method realizes multi-stage efficient dust removal and equipment self-cleaning, improves dust removal efficiency, and avoids secondary pollution.

This invention relates to the field of microbial culture technology, and more specifically, to a microbial fermentation culture tank for planting culture media. The tank includes a tank body, a motor fixedly mounted on the top of the tank cover, a stirring shaft fixedly connected to the bottom of the motor drive shaft, and a stirring paddle fixedly mounted on the outer side of the middle section of the stirring shaft. The invention is characterized by: a defoaming component positioned between the outer top of the stirring shaft and the inner wall of the tank; a scraper ring component positioned at the top of the defoaming component; and a homogenizing component positioned between the bottom of the defoaming component and the bottom of the stirring shaft. This invention uses a rotating stirring shaft to drive the defoaming paddle and collision blocks to rotate, causing the collision plates to collide with the collision blocks. This, in turn, causes the scraper ring to rotate and slide, scraping away the fermentation liquid on the inner wall. Simultaneously, the bottom stirring teeth can perform horizontal rotational stirring and linear reciprocating stirring perpendicular to the stirring shaft, resulting in a more uniform mixing density of the fermentation liquid at the bottom.

The invention relates to the technical field of double-medium tubular heat exchangers, in particular to an energy-saving heat exchanger of a coating machine drying oven. Comprising a frame defined by a left plate, an upper plate, a right plate and a lower plate. A snakelike heat exchange pipe is arranged on the inner side of the frame body; the outer wall of the heat exchange tube is sleeved with fins for heat exchange; two partition plates are fixedly connected between the upper plate and the lower plate; the inner side of the frame body is divided into a middle heat exchange cavity, a left collecting cavity and a right collecting cavity by the two partition plates; front and rear openings of the collecting cavity are fixedly connected with baffle plates; the top and the bottom between the two partition plates are fixedly connected with a rib frame; in the process that high-temperature waste gas penetrates through the heat exchange cavity of the heat exchanger, the driving motor is matched with the gear ring to drive the fins on the heat exchange pipe to rotate, so that the high-temperature waste gas can be in unobstructed contact with the fins at all positions in the process that the high-temperature waste gas penetrates through the heat exchanger from back to front, and then the heat exchange effect of the heat exchanger is improved; and the heat exchanger also has a self-cleaning function.

This invention provides a docking device and method for actively capturing floating pipes on the water surface, belonging to the field of nuclear power plant cold source interception net waste cleaning technology. The docking device and method for actively capturing floating pipes on the water surface includes a hull and a floating body unit, both of which float on the water surface. A docking male is provided at the bow of the hull. It also includes: a multi-degree-of-freedom moving unit installed at the bow of the hull; and a docking unit installed on the multi-degree-of-freedom moving unit for grasping the floating body unit, achieving active capture and precise docking of the floating pipe. Through the multi-degree-of-freedom moving unit, the conical docking structure, and sensor positioning, it automatically compensates for bilateral dynamic disturbances caused by waves and water flow, completing docking without manual assistance, significantly improving docking efficiency and accuracy, avoiding interface collision damage and leakage, and eliminating the safety risk of falling into the water during manual operation. It can still operate stably in complex sea conditions.

This invention discloses an ultra-high reflectivity, high weather resistance, and frost-resistant sandwich reflector for concentrating solar collectors. An anti-frost and snow-resistant superhydrophobic coating is located on the upper surface of ultra-clear semi-tempered float glass. A first anti-reflection layer is located on the lower surface of the ultra-clear semi-tempered float glass. A reflective layer is located on the lower surface of the first anti-reflection layer, an anti-reflective layer is located on the lower surface of the reflective layer, a metal-doped absorbing layer is located on the lower surface of the anti-reflective layer, and a second anti-reflection layer is located on the lower surface of the metal-doped absorbing layer. A fully tempered float glass support is bonded to the second anti-reflection layer on the lower surface of the ultra-clear semi-tempered float glass using a vacuum lamination process, forming a sandwich concentrating reflector. The edges of the sandwich concentrating reflector are sealed with an edge sealant. This invention not only ensures a reflectivity of 95.5-97% but also exhibits strong weather resistance, significantly reducing the defrosting time in winter, daily cleaning time and frequency, and slowing down the decay of reflectivity, thus extending its service life.
