4results about How to "Avoid re-adhesion" patented technology

This invention relates to the field of centrifugal separation technology, specifically to a cold precipitate centrifugal separation device and its application in the production of instant tea powder. The device includes: a base plate and a centrifugal tank fixed to the base plate, with a cover plate hinged to the top of the centrifugal tank; a filter tank rotatably installed inside the centrifugal tank, the outer circumferential wall of the filter tank having multiple circumferentially equidistant filter holes; a centrifugal assembly connected to the filter tank on the base plate; a rotary feeding mechanism disposed on the cover plate for guiding the cold precipitate into the filter tank for centrifugal separation; and a scraping assembly disposed on the cover plate, with a scraper connected to the scraper. The scraping assembly can control the movement of the scraper to break the continuous adhesive surface of the tea polysaccharide-containing filter cake and guide the material away from the filter tank, preventing the material from being re-adsorbed onto the screen due to residual centrifugal force or airflow disturbance.

This invention provides a three-dimensional drying chamber for lost foam casting, relating to the field of lost foam casting drying technology. It includes a steel frame structure, with a moving track bolted to the bottom of the frame. The moving track is equipped with a pick-and-place mechanism, and limiting damping mechanisms at both ends. A heating mechanism is mounted on the frame, and an auxiliary cleaning mechanism is located on the side of the frame. The auxiliary cleaning mechanism includes a cleaning platform bolted to the side of the frame, a support frame fixedly connected to the platform, a cleaning structure on the support frame, and an adsorption structure on the side of the support frame. This invention solves the technical problem of the lack of a cleaning mechanism for melted residue in lost foam casting drying chambers.

The utility model discloses a pickling device for steel, including base, the top of base is installed with pickling tank, the one side of pickling tank forms the bottom groove of downward extension, the bottom of bottom groove is installed with the oscillator, the one side of bottom groove is provided with the storage box for depositing pickling agent, the bottom of one side of storage box is provided with the liquid outlet pipe, the top of storage box is provided with the cover, and the top one side of storage box has the storage groove. The utility model provides a pickling device for steel, and pickling tank is supported through setting base, and the bottom groove of pickling tank one side extension cooperates oscillator, prevents the impurity after cleaning from adhering again on steel, and storage box is used for depositing pickling agent in bulk, and the liquid outlet pipe is convenient for pickling agent and is guided into pickling tank, realizes the convenient supply of pickling agent, and the cover can reduce the volatilization or pollution of pickling agent in storage box, and the storage groove can be used for placing the tool or small -size accessories required for pickling, and the operation convenience is improved.

The utility model provides a feeding device of an ultrasonic cleaning machine, belongs to the technical field of feeding devices, and aims to solve the problem that cleaned dirt is easy to accumulate between a transmission belt and a workpiece, so that the cleaning effect on the workpiece is influenced. Comprising a positioning mounting base, a plate chain conveying belt, a fixed transmission rack, a positioning supporting plate, a transmission mounting rod, a guide mounting base, a workpiece stirring claw and a cleaning agent storage box. The plate chain conveyor belt is arranged at the lower part of the positioning mounting seat; the fixed transmission racks are fixedly connected to the front and rear sides of the positioning mounting seat; the positioning supporting plate is fixedly connected to the outer side of the plate chain conveying belt. The transmission mounting rod is rotationally connected to the outer side of the positioning supporting plate; the guide mounting seat is in key connection with the outer side of the transmission mounting rod; the workpiece shifting claw is slidably connected to the outer side of the guide mounting seat; the cleaning agent storage box is in bolted connection with the lower side of the positioning mounting seat; according to the utility model, the condition of dirt accumulation is avoided, and the cleaning effect on workpieces is improved.
