Definitions
- This invention relates to an assembly for transferring solid particulate matter, with the assistance of pressurized airflow into a loading container, which may be a storage container, a processing tank, or other similar vessel. Even more particularly, the present invention relates to an assembly for transferring solid pelletized material, such as for instance a catalyst substance, into a loading container, wherein the pelletized material generates dust during the transfer process.
- a loading container which may be a storage container, a processing tank, or other similar vessel.
- the present invention relates to an assembly for transferring solid pelletized material, such as for instance a catalyst substance, into a loading container, wherein the pelletized material generates dust during the transfer process.
- acid processing tanks are upright vessels with a closed top.
- a plurality of levels or beds of catalyst is contained in each converter vessel.
- the loading takes place through the top of the converter in the first bed of catalyst and through opening in the sidewall of the converter in lower beds.
- the catalyst pellets being delivered by gravity, generate a significant amount of dust.
- the personnel who perform the loading operation by necessity have to wear facemasks, respirators, and similar protective gear to avoid breathing in the dust that heavily permeates the area where the loading takes place.
- a useful assembly for handling solid particulate matter is disclosed in U.S. Pat. No. 7,635,011, which teaches the use of a pressurized vessel for retaining a pre-determined quantity of the solid material.
- a transfer conduit connected to the vessel carries the solid material to a loading vessel, be it a processing tank, a storage vessel, or any other similar container.
- a discharge nozzle carried by a distant end of the transfer conduit has a plurality of perforations that allow removal of the dust particles by suction from the discharge nozzle.
- a separate dust removal conduit is secured immediately adjacent to the discharge nozzle for removal of the dust particles away from the discharge nozzle.
- the nozzle is also connected to a dust collection container.
- a vacuum-assisted suction force is created in the dust collection container to facilitate entrapment of dust particles generated during transfer of the solid material through the discharge container and carrying of the dust particles away from the discharge opening of the discharge nozzle into the dust collection container. While the assembly according to the '011 patent works satisfactory in many circumstances, there was observed a need for a better control of the transfer process for moving the solid particulate matter through the transfer conduit. Additionally, it was discovered that there may be a more enhanced dust entrapment device that may be used in the system.
- the present invention contemplates elimination of drawbacks associated with the prior design and provision of an improved loading system that improves the control over the transfer process for solid particulate matter while improving dust-collection capabilities.

- a source of pressurized gas retains a pre-determined pressure inside the pressurized vessel to facilitate movement of the particulate matter through the container and into a transfer conduit.
- the pressure inside the container can be manually or automatically controlled using a control panel.
- the pressure created in the container facilitates movement of the particulate matter through the transfer conduit to a distant end thereof, where a discharge nozzle is mounted.
- a balancing vacuum source creates a slight vacuum at the discharge nozzle assembly for removal of the dust particles from the transfer conduit.
- the removed dust particles are pulled into a dust collection vessel, where they settle on mesh sleeves suspended in the dust collection vessel in the path of flow from the dust collection conduit and an exhaust pump or fan.
- the dust particles are collected from the mesh sleeves by blowing air through the sleeves using an auxiliary surge tank.
- the dislodged dust particles fall under gravity into the bottom of the dust collection vessel and are removed therefrom into a container positioned below the dust collection vessel.
- the balance between pressurized container and the vacuum pull of the dust particles is maintained to facilitate efficient, dust-free delivery of the palletized material to the desired processing tank.

- a dust removal conduit 22 is in fluid communication with the discharge nozzle assembly 20 .
- the dust conduit 22 is connected to the discharge nozzle assembly 20 upstream from a discharge opening 98 of the discharge nozzle assembly 20 .
- the dust removal conduit 22 is operationally connected to a dust collection container, or vessel 26 and is in fluid communication therewith.
- a chamber 28 is formed in the dust collection vessel 26 .
- the pressurized container 12 is provided with a top lid 30 that allows loading of the container 12 from the top.
- the items to be transferred, for instance pellets 38 of the catalyst, are loaded by gravity into the upright container 12 .
- a conduit 32 fluidly connects the container 12 with a source of compressed (pressurized) air supply (not shown).
- a regulating valve 33 is mounted in the conduit 32 for regulating delivery of the pressurized air into the container 12 .
- a pressure indicator 35 is operationally connected to the container 12 ; the pressure indicator 35 is configured to detect pressure inside the container 12 during the loading operation.
- the container 12 is vertically oriented to facilitate movement of the solid particulate matter loaded into the container 12 from the top 34 to the bottom 36 thereof.
- the bottom 36 of the container 12 can be formed as an inverted cone to facilitate movement of the pelletized solid material in the interior of the container 12 toward to apex of the cone, which serves as a discharge outlet of the container 12 .
- the solid particles occupy the lower portion of the container 12 with the top portion 34 being filled with pressurized air to push the pellets downwardly and into the discharge 14 and then into the transfer conduit 16 .
- a gate valve 40 is positioned at the interface of the discharge opening 14 and the transfer conduit 16 to regulate movement of solid particles from the container 12 downstream into the transfer conduit 16 .
- the gate valve 40 moves between an open position and a closed position in response to a control signal from a control valve 42 mounted in operational relationship to the air supply conduit 32 and the regulating valve 33 .
- the container 12 is schematically shown as resting on a plurality of supporting legs 43 to allow the bottom 36 of the container 12 to be elevated above the conduit 16 .
- the height of the supporting legs 43 differs depending on the types of container design used.
- the solid pellets 38 move through the bottom discharge 14 into the conduit 16 in the direction away from the container 12 .
- the air pressure at the loading side 15 of the container 12 is approximately 375 CFM pushing the pellets 38 into the container 12 .
- the pressure inside the container 12 maintained by the compressed air supply as detected by the pressure indicator 35 is maintained at a level of between 5 p.s.i. and 15 p.s.i. In one of the preferred embodiments, that pressure is about 8 p.s.i. to start the movement of the pellets 38 from the container 12 into the transfer conduit 16 .
- the pressure at the discharge 14 is maintained at a sufficient level to allow movement of the pellets 38 through the transfer conduit 16 towards the discharge nozzle assembly 20 .
- one of the embodiments of the present invention for transferring sulfuric acid catalysts provides for pressurizing of the vessel 5 to 18 p.s.i.
- the discharge 14 on the bottom of the container 12 opens once the pre-determined pressure is reached.
- a compressor generating up to 400 cubic feet per minute (CFM) is used.
- the system 10 provides for the use of a vacuum exhaust pump 50 connected to the interior of the dust collection vessel 26 .
- a source of vacuum (not shown) can be a vacuum truck, which is delivered to the site and connected to the vacuum pump 50 by a vacuum delivery conduit 52 .
- a vacuum control valve 54 is mounted in the vacuum delivery conduit 52 .
- An exhaust conduit 56 is connected to the top of the dust collection vessel 26 .
- An exhaust valve 58 is mounted downstream of the exhaust pump 50 in the exhaust conduit 56 .
- pelletized items 38 move through the vessel 12 into the conduit 16 , they necessarily strike against each other; the friction causes small particles to be chipped off from the pellets 38 , generating dust that also travels through the container 12 and the transfer conduit 16 .
- the tiny solid particles then travel along the transfer conduit 16 and reach the discharge nozzle assembly 20 .
- a slight vacuum of approximately 0 to 5 p.s.i., at the discharge nozzle assembly 20 creates a large expansion of gas to about 3500 CFM. That air travels over the material being transferred through the discharge nozzle assembly 20 such that the dust particles are captured by the vacuum and pulled into the dust removal conduit 22 and then into the dust collection vessel 26 .
- an operator loading the palletized material 38 into a container detects that the pellets 38 exit the discharge nozzle 20 at a greater speed than necessary and that dust content gas increased. Such observation allows the operator to determine that the speed of travel of the palletized material through the transfer conduit 16 is too great.
- the system of the present invention provides for the use of a regulating door 60 , which moves between a closed and a plurality of partially open positions.
- the regulating door 60 is mounted in the discharge nozzle assembly 20 pivoting about a pivot point 62 in the direction of arrow 63 .
- the regulating door 60 can be rectangular in shape, as shown in FIGS. 4 and 8 .
- a knob 64 is secured to an exterior surface 61 of the door 60 to allow the operator to manually pull open the door 60 and thus reduce the vacuum strength pulling the pellets through the discharge conduit 16 .
- the door 60 can be moved into a fully open position or a plurality of partially open positions, giving the operator control over the speed of the pellet discharge at the exit point 98 .
- the discharge opening 98 is formed in a discharge nozzle plate 100 .
- the discharge nozzle plate 100 surrounds the discharge opening 98 , through which the pellets 38 exit the system 10 .
- the regulating door 60 is formed with an indentation 102 on an inner contact surface 63 thereof.
- a plurality of spaced-apart raised members 104 is provided on the contact surface of the discharge nozzle plate 100 . As any of the raised members 104 is aligned with the indentation 102 an matingly engages therewith, the door 60 opens in the selected position, allowing the discharge opening 98 to be fully closed, partially open or fully open, as the operator chooses.
- the dust collection conduit 22 is fluidly connected to an inlet opening 27 formed in the dust collection vessel 26 .
- a plurality of dust collection members 70 is suspended in the dust collection vessel 26 above a dust inlet opening above the inlet opening 27 .
- the dust collection members 70 are suspended in the dust collection vessel 26 in the path of suction flow between the dust collection conduit 22 and the exhaust pump or fan 50 .
- Each of the dust collection members 70 comprises a frame 72 , which can be formed by a thin rod bent into a generally U-shaped configuration.
- a mesh dust sleeve 74 is stretched over the frame 72 and is detachably secured on top by a clamp or rubber band 76 .
- the mesh sleeve 74 is formed from a porous flexible material with small openings 75 that allow air circulation through the dust sleeve while trapping dust particles on the exterior of the sleeve 74 .
- the dust particles may contain valuable materials, for instance silver (Ag), that is used in some catalysts.
- the system of the present invention comprises a means for dislodging and capturing or collecting the dust particles for recycling or disposal.
- a surge tank 80 is operationally connected to a surge conduit 82 mounted across the interior of the chamber 28 .
- the surge tank 80 is connected to a compressed air supply (not shown) through a supply valve 84 and to a control panel 200 of the system 10 through a surge control valve 86 .
- the surge conduit 82 has channels connecting the surge conduit 82 to the dust collection members 70 .
- the system operator can detect that the sleeves 74 have collected dust that impedes the air flow through the sleeves. Periodically, the operator can close off the valve into the transfer conduit 16 and switch off the exhaust pump 50 .
- the vacuum valve 54 is closed, thus isolating the dust collection vessel from the remainder of the system. If desired, the closing of the valves and vacuum supply can be performed automatically upon detection of certain pressure across the exhaust conduit 56 using the control panel 200 .
- the dust particles, which have settled on the sleeves 74 are dislodged from the sleeves 74 and fall under gravity into the bottom 29 of the dust collection vessel 26 .
- the dust particles 87 collect in the conical bottom 29 of the vessel 26 .
- the collected dust particles containing valuable metals and other materials can be sent to recycling and manufacturing of the catalyst pellets or disposed in a safe manner.
- system 120 shown in FIGS. 5-8 , is rather similar to the embodiment shown in FIGS. 1-5 and 9 , except in the system 120 , the delivery of compressed air supply into the inlet side of the transfer conduit 16 and into the pellet container 12 is performed automatically without human intervention using the control panel 200 . In both embodiments, substantially all dust particles, or a significant amount thereof is diverted from reaching the discharge opening 98 and escaping into the atmosphere. During a catalyst loading operation, the discharge nozzle end 98 is placed in the converter and the catalyst is distributed as required.
- the loading assembly of the present invention allows scrubbing of the catalysts or other pelletized solid particles and remove dust from the loading conduits before they escape into the surrounding area or reach the processing vessels, catalytic converters, storage containers, and the like. A careful balance must be observed between the amount of pressure created in the vessel 12 and the dust removal conduit 22 . Similarly, if the discharge nozzle 20 is selected for high-speed discharge, the dust particles may not have a chance to be directed into the flow moving towards the conduit 22 .
- the system 10 and the system 120 allow control of the catalyst being loaded into the container 12 as well as control of the vacuum pull by increasing the revolutions of the exhaust fan or pump 50 so as to create sufficient amount of low pressure at the precise point in the discharge assembly.
- the dust particles separated from the solid pellets are diverted from the discharge outlet into the dust collection conduit 22 and dust collection vessel 26 , thereby allowing the dust particles to be collected, containerized and recycled.
- the vacuum source should not overpower the positive air compressor delivering compressed air through the supply line 32 .
- the pressure in the container 12 is detected and controlled using the pressure indicator 35 so as not to overcome the vacuum force required for proper particle separation.
- the inlet pressure of about 5 p.s.i. at the delivery of the pellets into the container 12 and control of the exhaust vacuum fan 50 allows to create the necessary equilibrium for maximum collection of the dust particles without sacrificing the delivery of the palletized material for loading.
- the dust collection vessel 26 may have a capacity of moving 3,000 cubic feet per minute of the airflow.
- the vacuum generated in the conduit 22 and the pressure values in the container 12 can be different for different types of solid particulate matter.
