Definitions

  • This application relates to particulate handling apparatus, and in particular to a hopper for use in the loading of catalyst pellets into drums.
  • catalyst pellets are loaded into drums either for the transportation or storage of said catalyst pellets.
  • the drums are loaded using apparatus that is fixed in one position and which is not the subject of the present application.
  • the apparatus being used for loading said drums must in itself be portable. It would be economically very inefficient to have all the requisite apparatus for loading and unloading a reactor vessel permanently stationed adjacent to said reactor vessel.
  • Known apparatus for use in loading catalyst pellets into drums include a hopper, a hopper support frame, and optionally a roller conveyor.
  • an empty drum is placed beneath the hopper either directly onto the surface supporting the apparatus (here after "the floor") or, if one is being used, on the roller conveyor.
  • the drum is open ended and the open end placed upmost and directly beneath the hopper.
  • the drum is loaded from the hopper and the open end or mouth of the drum then sealed.
  • the drum is then either man-handled from beneath the hopper or, if a roller conveyor is being used, is rolled out from beneath the hopper.
  • the drum is then man-handled onto a pallet suitable for one or more drums and subsequently removed from the area of the hopper by a fork lift truck.
  • apparatus for the filling at least a pair of drums substantially simultaneously whilst minimising the manual handling of said drums.
  • a loading hopper in which the hopper is provided with an inlet port, at least two outlet ports, and division means arranged to substantially divide a stream of pellets entering the hopper via the inlet port and direct the divided stream of pellets towards each outlet port.
  • pellet' includes particulate material, shaped or formed bodies, or the like.
  • the division means may include the walls of the hopper which are shaped and dimensioned to substantially divide a stream of pellets entering the hopper via the inlet port and direct a stream of pellets towards each outlet port.
  • the hopper is provided with a pair of outlet ports.
  • the apparatus of the present invention may be configured to operate equally effectively with other numbers of outlet ports, most preferably three or four outlet ports.
  • the hopper is provided with two outlet ports and is so shaped and configured that the bisection of the stream of pellets is by way of the stream of pellets impacting an edge defined by the intersection of a pair of side walls of the hopper.
  • Said side walls preferably intersect at an acute angle so presenting a bisecting edge which may be a substantially sharp edge to a stream of pellets entering the hopper via the inlet port.
  • the side walls which define the bisecting edge also form a part of a substantially conical or pyramidal construction which narrows toward its vertically lower end to an outlet port.
  • the substantially pyramidal or conical construction serves to direct the pellets to the first and second outlet ports of the hopper.
  • the stream of pellets may be bisected by one or more baffles or dividing plates located within the hopper. Said baffles or dividing plates are preferably supported in their correct position by being anchored or fixed to one or more side walls of the hopper.
  • baffles or dividing plates gives a designer of a hopper according to the present invention a degree of freedom over the design of the outer wall of the hopper.
  • the stream of catalyst pellets enters the hopper with a substantially vertically downward direction.
  • the pellets then travel under the force of gravity past the division or bisecting means and, thence, to the outlet ports.
  • the catalyst pellets are transported to the hopper entrained with a conveying gas.
  • the conveying gas is drawn out of said hopper via one or more conveying gas outlet ports.
  • Each conveying gas outlet port is preferably located in such a position that it is very unlikely that any catalyst pellets entering the hopper would travel from the hopper inlet port to the conveying gas outlet port.
  • the conveying gas outlet ports are preferably attached, via ducting, to a means for inducing negative pressure relative to the pressure within the hopper, so causing conveying gas to exhaust from the hopper via the conveying gas outlet ports.
  • the hopper is provided with at least one aperture adjacent to each outlet port.
  • Each aperture is sealed with a transparent sheet of material so as to form viewing windows in the hopper. These viewing windows allow an operator of said hopper to ascertain the conditions within the hopper and, in particular, how full or empty the hopper is.
  • each outlet port Engaged with each outlet port is a reversible port closure means or valve to which, on the side remote from the hopper, there is attached a first end of a flexible hose or duct.
  • Attached to the second end of each flexible hose or duct is a drum filling lid of known type.
  • Each drum filling lid is essentially adapted to sealingly engage with the open mouth of a drum. The sealing engagement is adapted to be reversible so as to allow the removal of the drum filling lid once the drum is full.
  • drum filling lids adapted to be engaged with the outlet ports are all fixed to a support frame.
  • each drum filling lid is independently fixed on its own support frame.
  • the drum filling lid is provided with means to create a negative pressure in the drum being filled when the drum filler lid is sealingly engaged with the drum mouth.
  • Particularly preferred apparatus for inducing a negative pressure in the drum is provision of a dust line, or small bore pipe or duct, which provides communication for gas and dust between the inside of the drum, and either the inside of the hopper in the region of the conveying gas outlet port or ports, or directly into the duct or pipe connected with a conveying gas outlet port.
  • the apparatus of the present invention may further be provided with a hopper support frame.
  • the hopper support frame preferably includes at least two support posts which may be either permanently or releasably fixed to the hopper.
  • the support frame may, optionally, include one or more cross members fixing the support posts relative to each other.
  • the support posts are telescopic so that the apparatus may be adapted for use with drums and/or pallets of different vertical heights.
  • each support post is, preferably, fixed to a cross bar which, at either end of said cross bar, engages with ground engaging means.
  • This provides stability to the hopper and the support frame.
  • the ground engaging means for each cross bar are rollers, endless belt tracks, wheels or the like, so allowing the apparatus of the present invention to be rolled, assuming the surface on which it is resting is sufficiently flat and smooth.
  • the orientation of the axis of rotation of the rollers is fixed and substantially parallel and substantially perpendicular to the orientation of the longitudinal axis of each cross bar.
  • the support frame or frames for the drum filling lids are mounted on the hopper support frame and are so constructed and configured that they allow movement of the drum filling lids either together or separately between a first retracted position and a second extended position. Both retracted and extended positions are at vertically lower levels than the hopper outlet ports, when the hopper is orientated for use, with the retracted position being at a vertically higher level than the extended position.
  • the hopper support frame is so dimensioned and configured that it supports the hopper in such a position that the level of the mouth of a drum when ready for filling whilst that drum is sitting on a pallet suitable for lifting with a fork lift truck is between the levels of the retracted and extended positions of the drum filler lids.
  • the apparatus of the present invention having two outlet ports is transported by known means, such as a lorry, to a position adjacent to a reactor vessel. It is then connected with an appropriate, known, catalyst pellet transportation means.
  • a fork lift truck is employed to place a pallet bearing two or four empty drums, their mouths all facing vertically upwards, between the support posts and cross bars of the hopper support frame.
  • the support frame or frames for the drum filler lids are then manipulated to move the drum filler lids to engage with the mouth of an empty drum.
  • the filling lids are sealed to the mouths of the drums. If necessary, the operator can adjust the telescopic legs (if present) of the hopper support frame to ensure that the drum filler lids may engage with the mouth of the drums.
  • the drums with which the filler lids are engaged are next placed under negative pressure by known means not discussed herein.
  • the operator of the apparatus then opens the closure means to each outlet port causing catalyst to flow, both under the force of gravity and the pressure differential between the hopper and the drum, into the drum. Placing each drum under negative pressure relative to the hopper avoids needing to place an air lock or air vent in the drum filling lids.
  • the apparatus of the present invention is next rolled so that the drum filling lids are vertically above the mouths of the two remaining empty drums and the process for filling the drums is repeated.
  • the force needed for rolling the apparatus of the present invention between the filling positions may either be provided by a human, or by a motor, for instance an electric motor.
  • a fork lift truck is employed to pick up the pallet bearing the full drums and to transport it to a position of storage or onto a vehicle for transportation.
  • a fresh pallet bearing empty drums is then placed beneath the apparatus of the present invention and the above described actions repeated, with the exception of the initial setting up adjustments.
  • the apparatus of the present invention is particularly advantageous over currently known apparatus for drum filling both because of the minimalisation of the manual effort needed to handle the drums, and because of the increased loading rates for drums.
  • the previously known apparatus only loaded one drum at a time, whereas the present apparatus loads at least two drums at a time.
  • the present apparatus allows the use of bigger drums which would previously not have been usable because of the difficulty of handling said drums when full.
  • a hopper (2) is defined by walls (4, 6, 8, 10 and others not visible in the Figure) so as to create a volume that is comprised of a rectangular volume descending from which are two substantially pyramidal volumes.
  • the two substantially pyramidal volumes and the rectangular volume intersect at a bisecting edge (12).
  • Substantially vertically above bisecting edge (12) is an inlet port (14) into the hopper.
  • the inlet port (14) is adapted to engage with known apparatus for the transportation of particulate catalysts when entrained in a conveying gas.
  • the hopper (2) is provided with first and second outlet ports (16A, 16B respectively) and viewing windows (20). Not shown are conveying gas outlet ports. Said conveying gas outlet ports are located adjacent to the vertically uppermost edge of the face of hopper (2) opposite to viewing windows (20). Each conveying gas outlet port is in communication with a means for inducing negative pressure and, hence, for sucking conveying gas out of hopper (2).
  • each outlet port (16A and 16B) Attached to each outlet port (16A and 16B) is a plate valve (18A and 18B respectively).
  • Said plate valves (18A and 18B) may, by manual operation, be reversibly moved from an open position whereby catalyst pellets can flow through said plate valve to a closed position whereby catalyst pellets are prevented from exiting hopper (2).
  • each plate valve (18A, 18B) remote from hopper (2) is a flexible hose (22A and 22B respectively).
  • the ends of the flexible hoses (22A and 22B) remote from the plate valves (18A and 18B) are each engaged with and in communication with a drum filling lid (24A and 24B).
  • the drum filling lids (24A and 24B) are provided with means, not shown, for sealingly engaging with the open mouth of a drum.
  • each of the drum filling lids (24A and 24B) is provided with an aperture through said filling lid with which the respective hoses (22A and 22B) are in communication, and with means adapted to create a negative pressure in the drum when the filling lid is sealingly engaged with the mouth of the drum.
  • Both of the drum filling lids (24A and 24B) are fixed to a support frame (26).
  • the support frame (26) is, in turn, mounted on a hopper support frame (28).
  • Support frame (26) is so constructed that with a single lever action by an operator, the drum filling lids (24A and 24B) may be moved from the retracted position into engagement with the mouths of a pair of empty drums which would, when the apparatus were in use, be located in the position shown by dashed lines (38A and 38B).
  • Hopper support frame (28) is comprised of a pair of support posts(30), the upper ends of which are attached to hopper (2).
  • Support posts (30) are preferably telescopic and constructed in a known fashion. The advantage of support posts (30) being telescopic is that in addition to allowing the overall height of the apparatus of the present invention above the surface upon which it is supported to be adjusted, it enables the apparatus of the present invention to be packed to a smaller volume for transportation.
  • Cross bars (32) engage the surface upon which the apparatus of the present invention is resting via fixed direction rollers (34).
  • the rollers (34) are so configured and attached to cross bars (32) that the apparatus of the present invention may be rolled over a flat and hard surface in directions parallel to the principal axis of cross bars (32).
  • the apparatus of the present invention is used as described above.
