  • Patent number: 8028940
    Abstract: The disclosed trash comminution apparatus (TCA) is a device designed to work in conjunction with existing residential trash receptacles utilized by both municipal and private trash collection services. The TCA can pulverize, grind and shred most residential trash items into small pieces, while allowing non-shreddable material to be disposed of as well. In some embodiments, the TCA can be installed on the top of a commonly utilized trash receptacle. To install the TCA on a common receptacle, the hinged top of the receptacle can be removed. A rectangular opening can be cut near the top, on the back side of the receptacle. The TCA can then fit directly inside the top lip of the receptacle and can be bolted into the sides of the receptacle with a reinforcing metal band on both the interior and exterior of the lip of the receptacle. An electrical connection box with a three-prong electrical plug can be installed into the rectangular. The TCA can have a metal lid and a latch to latch the lid to the receptacle.

The variable frequency controlling system includes a thickness sensor, a speed-variable motor and a controlling module. The controlling module is electrically connected to the speed-variable motor and the thickness sensor, and includes a look-up table. The thickness sensor is used for detecting a thickness of an article fed into the shredder. The speed-variable motor is operated at a variable rotating speed. When a thickness-detecting signal is received by the controlling module, the operating data corresponding to the thickness-detecting signal are searched from the look-up table and outputted from the controlling module to the speed-variable motor, thereby controlling the speed-variable motor to be operated at a proper rotating speed. As a consequence, a power-saving purpose is achieved by the variable frequency controlling system.

  • Patent number: 7900858
    Abstract: A material reducing apparatus comprising a feed conveyor, for conveying material to be reduced, and a feed roller cooperating with the feed conveyor. An upwardly rotatable rotor carrying a plurality of strikers which facilitate reduction of the material to be reduced and an anvil cooperating with the plurality of strikers to facilitate further reduction of the material to be reduced. A grate assembly, located adjacent an arcuate path of the rotor, which permits sufficiently reduced material to pass therethrough. The material reducing apparatus further includes a failsafe system which comprising an accelerometer supported by the rotor and coupled to a control system such that the accelerometer, upon detection of the rotor contacting a hard material, sends a signal to the control system. If the signal indicates a sufficiently large material, the control system reverses a rotational direction of the feed roller so that the feed roll rotates to withdraw the hard material from contact with the rotor.

  • Publication number: 20110049278
    Abstract: A jet mill in which crushed material introduced into a crushing chamber is comminuted by gas being sprayed from a plurality of gas-jet nozzles, wherein high-efficiency pulverization is performed by optimizing various pulverization conditions according to the type of crushed material or other such properties. The direction in which gas is sprayed into the crushing chamber is variable adjustable; the spraying direction of each nozzle is displaced simultaneously by the electromotive actuator; swirl flow is produced in three dimensions, including the flow of a directional component that is perpendicular to the horizontal swirl flow; and a fine-powder discharge port of a first pulverization chamber and a fine powder introduction port of a second pulverization chamber are communicatingly connected by a ventilation duct.

  • Publication number: 20110024534
    Abstract: The invention relates to a pulper and to its method for recycling wastes and/or product residuals. The pulper comprises a tank is which a rotor is provided for defibrating the stock mixture to be recycled, as well as a screen for drawing off the defibrated outfeed from the tank, the rotor being powered by an electric motor comprising a drive shaft in active transmission with the rotor. In accordance with the invention the electric motor is configured as a three-phase synchronous motor for operation in a speed range from 0 to 1000 rpm. It is connected to the output of a frequency inverter controlled by a controller, the output of the drive shaft being directly connected to the rotor.

  • Publication number: 20100327091
    Abstract: Safety systems and methods are disclosed for controlling operation of office equipment, such as a paper shredder. In one example, the method includes enabling operation of an electric motor configured to drive at least one moveable component of an electronic office appliance. Upon detection of human motion within a prescribed safety zone defined by at least one passive infrared (PIR)-based motion detector during operation of the electric motor, the electric motor is disabled. In one example, the electronic office appliance includes at least two PIR-based motion detectors positioned near at least one moveable component of the electronic office appliance. Operation of the electric motor can be resumed after a predetermined time interval has elapsed without the detection of subsequent human motion within the prescribed safety zone.
