An overhead catalyst loading device eliminates the need for lower flanges of the overhead catalyst structural support frame or dedicated overhead trolley beams to prevent ash build up collecting on a SCR reactor box and provides an advantageous lifting mechanism suitable for integration into a SCR device. The overall width of the SCR device is reduced since the structural support frame in the SCR device fits in the gaps between catalyst blocks. No extra space is required on either side of the catalyst blocks for the structural support frame. The overhead catalyst loading device also minimizes the chance of injury during catalyst block installation by using a hydraulic actuated lifting mechanism for loading and unloading catalyst blocks into and out of a SCR device. Methods of lifting and loading and unloading a catalyst block are also presented therein.
A catalyst loading device, comprising:
A lifting mechanism, comprising:
A method of loading and unloading a catalyst block into an SCR device, comprising the steps of:
A method of loading and unloading a catalyst block into an SCR device, wherein a hydraulic pump provides pressure to a hydraulic cylinder in order to actuate and extend a linking rod at a first end, wherein forces are transmitted along the linking rod to a first end of a lifting arm, wherein the application of force by the hydraulic cylinder causes the lifting arm, a lifting rod, and a lifting cam to rotate about the longitudinal axis of the lifting rod, wherein the lifting cam engages a lifting frame of a lifting structure, and the force exerted by the hydraulic cylinder is transmitted into the lifting structure, causing it to be displaced vertically, thereby lifting the catalyst block coupled thereto, wherein once the catalyst block is moved to a desired position, the pressure exerted by the hydraulic pump is released, permitting the hydraulic cylinders and their attached linking rods to retract and the assembly of the lifting arm, lifting rod, and lifting cam to rotate in the opposite direction to lower the lifting frame, wherein the lifting frame reengages a support structure, and the catalyst blocks are de-coupled from the lifting structure.
A method of lifting a catalyst block, wherein a hydraulic pump provides pressure to a hydraulic cylinder in order to actuate and extend a linking rod at a first end, wherein forces are transmitted along the linking rod to a first end of a lifting arm, wherein the application of force by the hydraulic cylinder causes the lifting arm, a lifting rod, and a lifting cam to rotate about the longitudinal axis of the lifting rod, wherein the lifting cam engages a lifting frame of a lifting structure, and the force exerted by the hydraulic cylinder is transmitted into the lifting structure, causing it to be displaced vertically, thereby lifting the catalyst block coupled thereto.
