An electrical control system for slurry mixing includes a processing module, an input module, a display module and an inspection module. The input module is configured to input the configuration information and send an action command and the configuration information to the processing module. The inspection module is configured to obtain the status information and send the status information to the processing module. The processing module is configured to receive the configuration information and the action command from the input module and the status information from the inspection module, form a production action according to the configuration information or the action command, and then send the configuration information, the action information and the status information to the display module. The display module is configured to receive the configuration information, the action information and the status information, and display the configuration information, the action information and the status information.

A chemical injection system for connection to a chemical tank and a process line includes a pump box configured to attach to the tank, the pump box including a body defining an interior, a pump assembly disposed within the interior of the body of the pump box, and an injection assembly configured to be fluidly coupled to the pump box. The injection assembly includes an injection lance having a flange and a stem, a first seal abutting a first side of the flange of the injection lance, and a second seal abutting a second side of the flange of the injection lance.

An agitator assembly includes an agitator body, a shaft and a blocking part. The shaft is assembled to the agitator body and extends through a lead-through in the agitator body into the vessel, when assembled for use, and includes a sealing to seal the rotatable shaft. The blocking part arranged at the agitator body and including a shaft opening through which the shaft is arranged to extend, a mating surface to mate with the shaft which, when brought together by axial movement of the blocking part, provides a seal between the blocking part and the shaft, and the mating surface arranged at an axial distance from the sealing in the lead-through, and when brought together by the axial movement of the blocking part, provides a seal between the blocking part and the agitator body, and that the blocking part provides a closed space around the lead-through in the agitator body.

A motor is generally described. The motor may include an armature and a coil. The coil and armature operatively receive power from a power source. The power induces magnetic fields in the coil and armature to drive the armature. When power is removed, the coils reverse polarity to inductively decelerate the armature.

Apparatus includes a fire prevention system having a dispenser of a fire extinguishing substance, a blender operative to blend a mixture of wood particles, and one or more conduits located inside the blender. The one or more conduits are in fluid communication with a source of water and a source of wax. The fire prevention system is in fluid communication with the blender and the one or more conduits for dispensing the fire extinguishing substance into the blender or one or more conduits.

The present disclosure relates to a food preparation appliance comprising a rotatable tool for chopping and/or blending a food in a food preparation pot. The tool can be mounted for rotating and can be detachably connected to a shaft. The shaft can be at least partially outside the food preparation pot. A locking mechanism is provided for connecting the tool to the shaft in a locked manner. The locking of the tool to the shaft can take place automatically. The food preparation appliance can thus be cleaned with particularly little effort.

A mixing system includes an eductor, a supply connection connected to a reservoir for a primary fluid, a discharge connection, a storage container for a secondary substance, a centrifugal pump to convey the primary fluid through the supply connection, and a controller to control the centrifugal pump. The eductor includes a primary inlet for the primary fluid, a secondary inlet for the secondary substance, an outlet for a mixed fluid, and a suction chamber to suck the secondary substance, the primary inlet connected to the supply connection so that the primary fluid can flow from the reservoir into the eductor and the outlet connected to the discharge connection so that the mixed fluid can be discharged from the eductor. The secondary inlet is at the suction chamber and connected to the storage container. A closing device is between the suction chamber and the storage container.

A system that moves water to a vessel on a water body includes a retractable tube with water intake that descends to a selectable depth in the water body, a pump that moves water from the selectable depth through the retractable tube, an anchor assembly carrying the pump or retractable tube to the selectable depth and back again, and an indicator of the depth of the anchor assembly, pump, or water intake of the retractable tube in the water body. The anchor assembly includes a pole, a cantilever beam, a telescoping pole, a pole driving system, or a combination thereof. The system may include a gas delivery system configured to introduce a gas into the system's water flow and a mixing chamber or tube that mixes water and gas. Variations of the system provide a subset of these components, and can be combined with third-party components.
