A bulk material system generally consisting of a container having an upper wall, a vertical wall and an opening in the vertical wall; a support frame detachably mountable on the upper and vertical walls of the container; a hopper mounted on the support frame; a material conveying conduit mounted on the frame having an inlet communicating with an outlet of the hopper for receiving material therefrom and an end portion with an outlet insertable through the vertical wall opening of the container when the frame is detachably mounted on the container; and a conduit supported on the support frame having an outlet communicating with the material conveying conduit and an inlet communicable with a source of gas under pressure, function to supply gas under pressure to the material conveying conduit for pneumatically conveying material fed from the hopper into the material conveying conduit, therethrough, into the container.

A dust control apparatus and method for a bulk material handling transfer system having a chute comprising a pathway there through for handling varying volumes of bulk material flowing through the chute using gravity flow. A self-adjusting air restrictor gate is mounted in the chute for engaging the upper surface of flowing bulk material through the chute for restricting the air pathway during material volume flow variations to reduce dust emissions. The gate member contacts the upper surface of flowing bulk material and moves up and down in response to the flow of bulk material through the chute to restrict the flow of air to reduce dust. A counterweight mechanism and a damper helps maintain controlled contact of the air restrictor gate with the upper surface of bulk material flowing through the chute.

A bulk material handling system comprising an enclosure, a door frame, and an access door. The door frame is secured to a wall of the enclosure adjacent an access opening. The exterior surface of the door frame is devoid of horizontal surface portions when the enclosure is oriented with the wall of the enclosure in a vertical position. The access door is releasably secured to the door frame and is movable between a closed position and an open position. The exterior surface of the door is devoid of horizontal surface portions when the access door is in the closed position and the enclosure is oriented with the wall of the enclosure in the vertical position.

A bulk material handling system generally consisting of means for holding the material; means for conveying the material including a first conduit formed of a permeable material having an inlet communicating with an outlet of the material holding means and an outlet, a second conduit formed of an impermeable material encompassing and spaced from the first conduit, providing a chamber therebetween, and an auger disposed in the first conduit for transporting material received through the inlet to the outlet thereof; means for rotatably driving the auger; and means for supplying a fluidizing gas under pressure to the chamber between the first and second conduits.

The invention discloses bulk material conveying equipment. The equipment comprises a movable type hopper, a belt conveying system, a conveyor support, a driving device, a sensor and a controller, the movable type hopper comprises a hopper body and a hopper support, and the hopper body is arranged on the hopper support; the feeding end of the belt conveying system is located below a discharging opening of the hopper body and hinged to the hopper support, and the discharging end of the belt conveying system is hinged to the conveyor support; the controller is electrically connected with the sensor and the driving device and used for controlling the driving device to act according to a signal fed back from the sensor. In the operation process, the sensor directly or indirectly obtains the angular displacement between the belt conveying system and the hopper support (or between the belt conveying system and the conveyor support), when the angular displacement exceeds a preset range, the controller controls the driving device to work, the driving device drives the conveyor support to move, thereby it is guaranteed that the feeding end of the belt conveying system is matched with the discharging opening of the hopper body all the time, and material leakage is prevented.

The invention belongs to the field of continuous operation bulk material loading and unloading machinery, and in particular relates to a bucket wheel stopper of a bucket wheel stacker and reclaimer. The technical gist of the present invention is that the bucket wheel stopper device of the bucket wheel stacker and reclaimer includes a rake base, a stopper rake, a mounting seat and an electric push rod; the rake base is fixed on the bucket wheel stacker The front end of the main beam of the arm frame of the material machine, the lower end of the retaining rake is hinged with the base of the material rake, the mounting seat is fixed above the front part of the main beam of the arm frame of the bucket wheel stacker and reclaimer, and the electric push rod is installed on the On the mounting seat, the upper part of the retaining rake is hinged with the electric push rod. The invention is simple in structure, easy to disassemble, can prevent material from collapsing during material retrieving operation, and also plays the role of loose material at the same time.
