A robotic pool or tank cleaner is propelled by water jets, the direction of which is controlled by the direction of rotation of a horizontally mounted pump motor within the pool cleaner housing, having a propeller attached to either end of the motor drive shaft which projects from opposing ends of the motor body, each of the propellers being positioned in a water jet discharge conduit that terminates in discharge ports in opposing ends of the housing. Each discharge conduit has a pressure-sensitive flap valve downstream of the respective propellers. When the propellers rotate in one direction, the water is drawn through one or more openings in the base plate, passes through one or more filter assemblies associated with the pool cleaner and is discharged through one of the discharge ports as a water jet of sufficient force to propel the pool cleaner along the surface being cleaned.

According to an embodiment, at first, a template is put into a cleaning bath containing a cleaning liquid inside a first process chamber. Then, an inactive gas is supplied into the first process chamber and the cleaning liquid is heated, so as to set temperature and pressure conditions that turn the cleaning liquid into a supercritical fluid state or subcritical fluid state. Then, the template is immersed in the cleaning liquid in the supercritical fluid state or subcritical fluid state for a predetermined time period.

There is disclosed a system for cleaning and disinfecting allograft material. In an embodiment, the system includes a sterile bag and a motorized paddle blender. The sterile bag having an outer wall configured to withstand blending forces, at least one paddle contact section, and an allograft retaining section separate from the at least one paddle contact section. The motorized paddle blender having at least one paddle configured to apply blending forces on the sterile bag on the at least one paddle contact area, a motorized portion to actuate the at least one paddle, and a door component configured to hold the sterile bag adjacent the at least one paddle. The at least one paddle and the allograft retaining section are configured to prevent the paddle from contacting the allograft material when the blending forces are applied on the sterile bag on the at least one paddle contact area.

The invention relates to: an apparatus (1) for the post-cleaning of 3D objects (90), which are printed from a light-curing resin formulation and comprise uncured residues of the resin formulation which adhere to the surface and have non-translucent and insoluble particles; and the use of a corresponding apparatus. The apparatus (1) comprises a cleaning chamber (2), which can be filled with a liquid cleaning agent (20) and has an agitator (5), for receiving the 3D object (90) to be cleaned, wherein a contamination detector (8), which is connected to a control unit (11) and determines the optical density of the cleaning agent (20), is provided for checking the remaining cleaning capacity of the cleaning agent (20), wherein the contamination detector (8) is located in an area kept free of non-translucent and insoluble particles above a predefined size in the cleaning agent (20). The determined optical density is used to determine the cleaning capacity of the cleaning agent (20).

The invention is generally a system for drying, recycling, and washing off residual resin from three-dimensionally (3D) printed objects. Exemplary systems may include a wash reservoir, a fan module, and one or more air exchange vents. The wash reservoir contains a wash solvent and a propeller fully or partially submerged into the wash solvent. The propeller splashes the wash solvent upwards to disperse on the 3D printed object, thereby largely washing away the resin residue present in the 3D printer object. The fan module is connected to the wash reservoir to create a positive or negative air pressure inside the wash reservoir, thereby redirecting the airflow to the wash reservoir. The air exchange vents are provided between a splash guard and a platform/lid of the wash reservoir to act as an air intake when the fan module blows air out of the wash reservoir and as an exhaust vice versa.

The invention is generally a system for drying, recycling, and washing off residual resin from 3D-printed objects. Exemplary systems may include a system for drying off residual resin from 3D-printed objects. The system may include a wash reservoir including a chamber for housing the 3D printed object and containing a wash solvent or liquid solvent adapted to at least partially remove residual residue present in the 3D printer object. Air exchange vents provided between a splash guard or a lid of the wash reservoir may be adapted to act as an air intake or an air exhaust. An airflow module in fluid communication with the air vents and the chamber may be adapted to create a positive or negative air pressure inside the wash reservoir for redirecting airflow to the chamber housing the 3D printed object, and blowing air out or into the chamber to dry the 3D-printed object.

A multi-axis variable-speed hot washing machine is provided, including a cleaning chamber, a drive apparatus, and a rotation mechanism. The rotation mechanism is arranged in an inner cavity of the cleaning chamber and is in transmission connection with the drive apparatus. At least one or more groups of rotation mechanism is arranged. The inner wall of the cleaning chamber is provided with a scraping mechanism that enhances a squeezing and frictional cleaning effect on a to-be-cleaned material.

A multi-axis variable-speed hot washing module and a hot washing method thereof are provided. The multi-axis variable-speed hot washing module includes a storage assembly, a dehydration assembly, and one or more multi-axis variable-speed hot washing machines, where the multi-axis variable-speed hot washing machine is connected to the storage assembly and the dehydration assembly. Batches of materials are stored in the storage assembly. When cleaning, the materials are put from the storage assembly into one or more multi-axis variable-speed hot washing machines, and medicinal water is added. The multi-axis variable-speed hot washing machine replaces functions of a hot washing machine, a screw, and a friction machine, and has relatively large mechanical friction on the materials during cleaning. The materials after being hot washed by the multi-axis variable-speed hot washing machine are transported to the dehydration assembly for dehydration, so as to implement separation of cleaning water and the materials.

The invention is a system for drying, recycling, and washing off residual resin from 3D-printed objects. Some aspects of the invention include a system for recycling solvents used to clean the 3D-printed objects in a washing chamber. The recycling system may include one or more solvent reservoirs that store a solvent for cleaning residual 3D-printing material off of 3D-printed objects, a wash chamber adapted to clean the 3D-printed objects, and a solvent recycling module. The solvent recycling module receives a saturated solvent from the one or more solvent reservoirs, evaporates or condenses the saturated solvent to remove residual 3D-printing material from the saturated solvent, and returns clean solvent to the one or more solvent reservoirs of the system.
