The waste shredding device according to the invention comprises: at least one shredding shaft; an internal combustion engine; a first and a second powertrain between the internal combustion engine and the shredding shaft; at least one energy converter coupled to the internal combustion engine in the first powertrain for converting mechanical energy of the internal combustion engine into storable energy; at least one auxiliary motor supplied with the storable energy in the first powertrain for introducing mechanical energy into the first powertrain; and an energy store for storing at least part of the storable energy and for at least partially supplying the at least one auxiliary motor with the storable energy, in particular for storing storable energy in the event of periods with low power demand and for delivering energy in the event of periods of high power demand.

The present invention relates to the field of food waste disposers, and, more particularly, to food waste disposers with embedded sprinkler assemblies.

A well tool assembly, system, and method for handling well debris is described. The assembly includes an electric submersible pump (ESP) configured to be positioned within a wellbore and a well debris cutting tool configured to be positioned downhole relative to the ESP within the wellbore. The ESP is configured to rotate in a first direction to pump well fluid in an uphole direction. The well debris cutting tool is configured to rotate in a second direction opposite the first direction and to grind debris carried by the well fluid in the uphole direction.

A food waste disposer includes: a housing; a grinding case positioned inside the housing and configured to be separable from inside of the housing to outside of the housing and treat food waste; a rotating grinder configured to treat the food waste by rotating inside the grinding case and rotatably coupled with respect to a bottom surface of the grinding case; a grinder rotating shaft inserted in the rotating grinder and configured to rotate together with the rotating grinder; and a driver positioned below the grinding case and configured to provide rotation power of the rotating grinder, wherein the driver includes: a driving motor configured to generate power; a shaft driving gear configured to rotate by receiving power of the driving motor; and a connecting shaft configured to be rotatable within a range of a first angle with respect to the shaft driving gear, wherein one end of the connecting shaft is inserted in the grinder rotating shaft and another end of the connecting shaft is inserted in the shaft driving gear to transfer power from the shaft driving gear to the grinder rotating shaft.

A food waste disposer includes a housing, a grinding case inside the housing to dispose of food waste, a valve assembly mounted to a lower portion of the grinding case, and a driving device arranged on one side of the valve assembly to operate the valve assembly. The grinding case includes a discharge hole formed on a bottom surface. The valve assembly includes a valve member configured to open or close the discharge hole. The driving device includes: a driving motor to generate power; a power transmission member connected to the driving motor and configured to be moved in a first direction and a second direction opposite to the first direction; a holding member that rotates based on the movement of the power transmission member and connects to the valve member to guide an open or closed state of the valve member; and a sensor in contact with the power transmission member.

A food waste disposer includes: a housing; a grinding case positioned inside the housing, configured to grind food waste, and separable from the housing, wherein a discharge hole is formed in a bottom of the grinding case; a valve assembly coupled to the grinding case below the discharge hole and configured to open or close the discharge hole, the valve assembly protruding below the grinding case; a storage case positioned below the grinding case and configured to store the grinded food waste from the grinding case; a transfer tube positioned between the valve assembly and the storage case and configured to transfer the grinded food waste from the grinding case to the storage case; and a connector coupled to the transfer tube, wherein a shape of the connector is deformable upon the valve assembly resting on the connector.

A cutting blade assembly establishes a bidirectional and/or multifaceted scissor-type cutting action to efficiently and effectively process various types of debris encountered by the cutting blade assembly. The assembly includes a cutting plate and a cutting hub configured for relative rotation. A cutting slot is formed in the cutting plate and intersects the axial face to define a cutting edge at the intersection of the cutting slot and the axial face. The cutting hub has a cutting arm positioned adjacent to the axial face. When the cutting plate and the cutting hub undergo relative rotation, the cutting arm passes adjacent to the cutting edge to perform a scissor-type cutting action.

The present disclosure provides a kitchen waste disposal system. The kitchen waste disposal system includes a garbage disposal having a top opening connected with a water outlet of a sink and a side opening connected with a drainage pipeline, an electric control valve in series with a water supply pipeline of the faucet, and a control box. The control box is configured to start the garbage disposal and turn on the electric control valve in response to a system starting signal. And the control box is further configured to stops the garbage disposal and shut the electric control valve in response to a completion state of a cleaning task of the garbage disposal. Based on present disclosure, start and stop of the garbage disposal and water source of the faucet are synchronously controlled by the control box, thereby simplifying manual operation of a user.
