Description

DK 181490 B1 1
The present invention relates to a pneumatic conveying system for collecting objects and transporting them to a collecting unit through a discharge convey line, the system comprising - a loading unit adapted to receive said objects and connected to an inlet convey line and an outlet convey line, air/gas flow allowed to pass through the inlet convey line, the loading unit and the outlet convey line, - said outlet convey line air/gas flow connected by convey lines to the discharge convey line, - said system comprising an air/gas pump adapted to generate an air/gas flow through the inlet convey line into the loading unit, - and that the system (1) further comprises a control system.
The invention also relates to a method for collecting and transporting objects through a pneumatic conveying system from a loading unit through a discharge convey line to a collecting unit to which the objects are delivered, an air/gas flow is flowing from an inlet convey line into the loading unit, and an air/gas pump is pumping air/gas through the inlet convey line, and a control system is controlling the pressure in the pneumatic conveying system.
Further the invention relates to use of the pneumatic conveying system for performing the method.
Finally, the invention relates to use of the pneumatic conveying system for a container return system for waste material. This waste material may be items such as empty beverage bottles and cans of any size and material such as, plastic, steel, aluminum, glass, plastic said waste material is recycling waste material.
Pneumatic conveying systems are used for transporting different kind of material such as food, corn and granulates. Generally, air is blown through
DK 181490 B1 2 pipes via a pressure blower and similar in order to move the material through the pipe. In this way the material in question can be moved from one point to another point.
US 6164492 B discloses a pneumatic product vending and delivery system.
The system transports products such as bottles from a remote storage location to a vending terminal where a costumer may select a specific bottle through a control panel. A blower assists in transporting the bottles through the tube, The system is not adapted for transporting empty packaging such as bottles and cans form a delivery station to a container.
US 4180354 discloses a pneumatic tube transmission system for transmitting a carrier in which an object is placed from one terminal to a remote terminal to allow delivery of the carrier into an open remote terminal. When the carrier is being transferred from the first terminal to the remote terminal, the carrier is positioned in the first terminal and the blower is activated to de liver positive pressure air through the first airline. A second airline draws a partial vacuum on the second end of the transmission line at the remote terminal. This forces the carrier to move through the line to the remote terminal where the object is removed from the carrier. The system is not suitable for transporting objects continuously.
BE 710678 discloses a pneumatic tube system where a suction in the tube sees to that objects such as bottles are transported through the tube. The system requires that each object is placed in the tube one by one.
A container return system is generally arranged to collect waste containers for recycling. This may include used emptied beverage bottles and cans, or other waste material.
The container return system must collect large numbers of waste material for recycling in a short period of time. In many installations, the container return
DK 181490 B1 3 system delivers the received objects to a backroom receiving facility and the required space here can be considerable. Further it can also require means for sorting and storing the received objects. The space requirement and the complexity cause cost to the system.
In a typical installation, the crushed or compressed objects are transferred to a box and stored in plastic bags. The plastic bag is replaced when full. This also requires available space to store the full plastic bag and is time consuming. Further the container return system is often stopped when the box is full and an empty one is placed.
In order to handle recycling packages such as bottles and cans it is common to transport the objects on a transport band. This transport band runs from a delivery station where the customer puts the bottle/can and to a box where the bottles/cans are selected. Such system is known from EP 0612046 A.
It comprises a front panel a receiving opening for the bottles/cans and a transfer conveyer to transport the bottles/cans to a collecting box.
These systems are quite time consuming for the customer as the system is fed one by one, that is the customer must wait for the bottle /can to disappear before a new one is fed to the system. Further the collecting boxes are filled in short time and must be replaced by a new one. This is also time requiring and requires staff just for emptying the boxes.
With other words it is desirable to be able develop an improved convey system for collecting and transporting waste material in such a way that the waste material can be handled without any delay. The waste material is transported away from the delivery station so fast that the user just can empty large portions of the waste material into the delivery station without any risk for overloading the system.
The present invention seeks generally to improve conveying system for collecting and transporting objects such that the abovementioned insufficiencies and drawbacks of today’s conveying systems are overcome or at least it provides a useful alternative.
DK 181490 B1 4
Up to this day, prior art has failed to teach a simple and yet reliable and inexpensive conveying system which in a safe and reliable manner, without substantially increasing the cost of the system, is able to satisfy the abovementioned much desired characteristics of the mentioned conveying system.
According to the invention, a pneumatic conveying system is provided, as per the introductory part of this specification, and wherein - it comprises a pressure blower for providing pressurized gas/air, said pressure blower air/gas flow connecting with the discharge convey line, - the pressure blower is by a first convey line air/gas flow connected to an injector and arranged to form a negative air/gas pressure in the outlet convey line, - and that the control system is configured to control the air/gas pressure from the pressure blower and the pressure from the air pump, by said pressure the objects pass from the loading unit through the outlet convey line and further through the injector and the discharge convey line into the collecting unit.
The pressure blower may comprise any type of air-source such as a blower, air pump, fan, or other device capable of creating a pressure differential and for forcing air or other fluid, under pressure, through the convey line. As such, the pressure blower is configured to generate a positive air-pressure for purposes of introducing air into the first convey line and an air flow with a certain laminar flow velocity in the loading unit and for causing an under- pressure in the outlet convey line. This causes the objects material introduced into the convey lines to travel through the convey lines. The pressure blower is configured to generate a negative air pressure within the outlet convey line below an ambient atmospheric pressure. The air/gas pump is required to generate a pressure of 1 bar above ambient atmospheric pressure in the inlet convey line.
DK 181490 B1
As the waste material - such as empty plastic bottles or cans - drop down in the loading unit and reaches the bottom of this, the laminar flow in the loading unit caused by the pressure difference between the inlet convey line and the outlet convey line is sucked into the outlet convey line and passes through 5 the injector and further to the discharge convey line. From here it is dropped down into the collecting unit which is typically a big container placed outside the building where the system is placed.
In this way the convey system can operate nearly through the whole day without any interruptions, as such a container can hold more than 150 times what a bag used in the known systems is capable of. Further the system does not require staff inside the building being responsible for watching the system being full and stopping it each time a box/bag is full. The full container - placed outside the building where the system is placed - is driven directly away without bothering any inside-staff. An additional benefit is that the plastic bags used in the existing systems are not necessary.
The system combines pneumatic vacuum transport and pneumatic overpressure transport and the control system controls the two pressures in such a way that we have nearly even pressure (0,9-1 bar) in the loading unit, and a laminar flow through the loading unit of around 20-30 m/second. The waste material is in this way pushed into the inlet convey line, where the under-pressure sucks the material to the discharge convey line from where it is dropped down into the container. The injector let the material pass through, while the injector also causes an under-pressure in the outlet convey line, as the pressurized air from the pressure blower passes through the injector.
According to one embodiment the injector is gas/air flow connected by a second convey line to the outlet convey line, the injector is further gas/air flow connected to the discharge line, said injector allowing the objects to pass through the injector and leave the injector through the discharge convey line.
The pressurized air is passed through the injector and to the discharge
DK 181490 B1 6 convey line, to which it is directly connected. As the injector also have a connection to the outlet convey line of the collecting unit through the second convey line, the flow from the blower through the injector makes an under- pressure in the second convey line and thereby in the outlet convey line of the loading unit.
According to one embodiment the discharge line comprises at least one first portion with a diameter d1 placed directly in connecting with the injector, and a second portion with a diameter d2 placed in a distance to the injector said d2>d1.
By changing the diameter of the discharge line making it bigger the pressure in the line/tube is reduced. The laminar velocity is around 10-15 m/sec in the region with the diameter d2. Hereby the material falls down into containers in a regulated manner, and without it being pushed out of the system with too much force. It falls quite easily into the container.
The two regions are connected by a conic transition tube.
According to one embodiment the control system is adapted to control the pressure in the system in such a way, that an laminar airflow in the loading unit is around 15-35 m/s, and the pressure in the outlet convey line is below 1 bar an ambient atmospheric pressure, and the pressure in the inlet convey line is above 1 bar an ambient atmospheric pressure.
The control system sees to that the air flow velocity in the loading unit is suitable, that is around 15-35 m/s, preferably 20-30 m/s and more preferably 25-30 m/s. This is done by regulating the pressure in the inlet convey line and the outlet convey line. When the waste material leaves the loading unit the under-pressure in the outlet convey line sees to, that the waste material is sucked up to the injector and from her is pushed out caused by the airflow from the pressure blower passing through the injector.
According to one embodiment a horizontal tube connects the pneumatic inlet
DK 181490 B1 7 and outlet convey lines two convey lines directly with each other, and a hopper is placed above the tube and connected to the tube and with an opening in the bottom allowing the objects to drop down into the tube through an opening in said tube.
The tube acts in this way as the bottom of the collecting unit/the hopper and the tube is typically an integrated part (made in one) of the inlet and outlet conveying lines. The collecting unit is physically and directly connected to the tube. The collecting unit is formed as a hopper, and comprises an opening in the bottom matching an opening of the tube. The hopper is typically connected to the tube by welding the lower edge of the hopper to the outside wall of the tube.
According to one embodiment that the outlet convey line comprises openings placed at the lower part of the wall of the outlet convey line and, in a region, close to the loading unit.
The system may be contaminated by residues from the waste material.
Waste containers returned for recycling, such as empty beverage bottles or cans, often contain residual liquids, which may come into contact with the system. In order to clean the system, the outlet convey line has 10-20 openings with a diameter each of 2-3 mm placed at the lower part of the wall of the outlet convey line. When water is dropped down in the loading unit it is sucked into the outlet convey line and due to the small openings, air from the outside is also sucked into the outlet convey line, working as an injector.
This causes the water to atomize and is sucked further into the system cleaning it.
According to one embodiment the pneumatic conveying system further comprises a compressor adapted to compress and/or tear apart the objects before the objects reach the loading unit.
Before the material is dropped into the loading unit is may be compressed, depending on what material we are talking about. Further, sometimes it is
DK 181490 B1 8 necessary to tear the material into small pieces, which also can be done before dropping it down into the loading unit.
According to one embodiment the collecting unit is a container with a space- volume of at least 2 m? preferably more than 2 m3 more preferably more than m? placed at an outlet of the discharge line for catching the objects falling down in said container.
Using big containers - normally placed outside the building where the system is placed — removes the need to collect the material in bags. The material 10 simply drops down in the container as it is, that is compressed or not compressed. The need to stack bags with the material for recycling is hereby removed.
The containers the containers can be as large as 6,5*2,5*3 m3 that is 48,75 m2. The container may also be a big plastic bag attached to the outlet.
According to one embodiment all the convey lines including the inlet convey line, the outlet convey line and discharge convey line are pneumatic transfer tubes.
By pneumatic transfer tubes is to understand, that the tubes are transporting under-pressure or over-pressure gas/air and are able to withstand the different pressures.
The invention also concerns a method for collecting and transporting objects through a pneumatic conveying system as described in the introductory part of the description and where a suction is provided in an outlet convey line connected to the collecting unit, said suction is provided by a pressure blower to which the outlet convey line is air/gas flow connected, the pressure blower blows air/gas through a first convey line through an injector causing the suction in the outlet convey line, a control system is controlling the pressure in the conveying lines so the
DK 181490 B1 9 pressure in the inlet convey system is above 1 bar an ambient atmospheric pressure, and the pressure in the outlet convey system is below an ambient atmospheric pressure thereby providing a laminar air/gas flow velocity in the loading unit, whereby the objects are moved through the conveying lines into the collecting unit.
According to one embodiment a second convey line between the injector and the outlet convey line provides the suction in the outlet convey line as the pressurized air from the pressure blower flows through the injector.

FIG. 1 is a perspective view of a pneumatic conveying system according to the invention.
FIG. 2 is a perspective view of a loading unit used in the pneumatic conveying system shown in fig 1.
FIG. 3 is a sectional view through an injector used in the pneumatic conveying system shown in fig 1.
The invention will be explained with reference to fig. 1. This shows the system 1 according to the invention, where an object 2 such as a plastic bottle is thrown down in a loading unit 4 for being transported through conveying lines/tubes. The object 2 is typically delivered from a deliver- station placed in a store, where the customer delivers his bottles/cans back to the store in order to have the waste objects 2 recycled. An object 2 is also seen in fig. 1 leaving the system through an outlet 14 of a discharge convey line 7. The objects 2 - delivered to the system 1- is delivered as a continuous flow. The customer may simply empty a whole sack of objects 2
DK 181490 B1 10 into the deliver-station as the system 1 is able to receive and handle the objects 2 without any delay.
The system 1 comprises the loading unit 4 that receives the objects 2. The loading unit 4 is explained in detail with reference to fig 3. The loading unit 4 is physically connected to an inlet convey line 5 — a tube — and an outlet convey line/tube 6. Air/gas is flowing through the inlet convey line 5, the loading unit 4 and the outlet convey line 6. The outlet convey line 6 is flow connecting with an injector 11 through a second convey line 12, which is also air/gas flow connected to the discharge convey line 7. A pressure blower 8 provides pressurized gas/air and is through a first convey line 18 air gas connected with the injector 11 and thereby the discharge convey line 7.
The pressure blower 8 forms a negative air/gas pressure in the outlet convey line 6 due to the established gas/air flow lines through the injector 11.
An air/gas pump 9 generates an air/gas flow through the inlet convey line 5 into the loading unit 4. A laminar airflow is then obtained in the loading unit 4: around 20-30 m/s, due to the pressure in the outlet convey line 6 is below 1 bar an ambient atmospheric pressure (suction), and the pressure in the inlet convey line 5 is above 1 bar an ambient atmospheric pressure.
Thereby the objects 2 pass from the loading unit 4 through the outlet convey line 6 and further through the injector 11 and the discharge convey line 7, through the outlet 14 of the discharge convey line 7 into the collecting unit 3. The pressure is controlled by a control system 10.
The discharge convey line 7 comprises a first portion 15 with a diameter d1 of the tube of around 200 mm placed directly in connecting with the injector 11. A second portion 16 with a diameter d2 of the tube of around 400 mm is placed in a distance to the injector 11. The two pieces are connected to each other with a conic transition-tube. By increasing the diameter of the
DK 181490 B1 11 tube close to the outlet 14 the flow velocity of the air/gas is reduced and the objects simply falls down into the container placed underthe outlet 14.
The construction of the loading unit 4 and its relation to the inlet and outlet conveying lines 5,6 will be explained with reference to fig 2. It comprises a hopper 20 physically connected to a horizontal tube 19. The horizontal tube 19 comprises the two convey lines 5,6 connecting them directly with each other. The hopper 20 is placed above the tube 19 and is connected directly to the tube 19 and with an opening in the bottom allowing the objects 2 to drop down into the tube 19 through an opening in the tube 19. The whole construction is supported by a frame 21. The tube 19 act as the bottom of the loading unit/hopper 4,20.
The outlet convey line 6 comprises openings 17 placed at the lower part of the wall of the outlet convey line 6. They are placed in a region close to the loading unit 4. Air is sucked into the tube 6 due to the under-pressure, and when water is dropped down in the loading unit the water is atomized and sucked through the whole system cleaning it.
Fig 3 is a sectional view through the injector 11. The arrows show the airflow through the injector 11 and it also shows an object 2 passing through the injector 11 caused by the suction provided by the airflow - from the pressure blower 8 - through the injector 11. When the object 2 has passed the injector 11 is pressed out of the conveying line due to the pressurized air/gas from the pressure blower 8.
The objects may be compressed or teared apart by a device before they are dropped down in the loading unit 4. This device is not shown in the figures.
