Description

Technical Field

[0001] The invention relates to the technical field of centrifugal fans, in particular to an air suspension centrifugal dust collecting device. Background Art

[0002] An air suspension centrifugal blower is a mechanical device that removes dust from the indoor air environment by pumping dust-laden air from the room to the outdoors. It can have built-in dust removal and dust collection components or external dust removal equipment.

[0003] For air suspension centrifugal blowers equipped with dust removal and dust collection components, the filtered dust needs to be manually discharged from the body after shutdown. The shutdown dust discharge method will reduce the dust removal efficiency of the air suspension centrifugal blower, and is not suitable for air dust removal operations in an environment where low air dust content needs to be maintained continuously. For example, an air suspension centrifugal blower with a dust removal function disclosed in Chinese invention patent publication number CN117231569A can filter the gas through the cooperation of an elastic ring frame, an elastic connecting plate and an elastic filter screen through the provision of a dust removal component when the equipment is running. At the same time, the dust can be cleaned through the cooperation of a cleaning sheet and a cleaning brush to prevent dust from adhering to the elastic filter screen and affecting the filtering effect. At the same time, the cleaned dust can be stored in the cone formed between the elastic ring frame, the elastic connecting plate and the elastic filter screen as the gas is blown until the elastic filter screen is reset after the equipment stops to push out the collected dust.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 12 An air suspension centrifugal dust collecting device comprises a motor 1, a volute 2 and a turbine 3. The volute 2 is mounted at one end of the motor 1, and the output shaft of the motor 1 extends into the volute 2 and is fixedly connected to the turbine 3; an air guide box 4 is fixedly sleeved on the outer circumferential surface of the volute 2, and an arc-shaped guide cavity 5 coaxial with the volute 2 is formed in the air guide box 4; the guide cavity 5 communicates between the air outlet of the volute 2 and the air outlet pipe 6 on the air guide box 4; the turbine 3 is driven to rotate by the motor 1, and the air around the air inlet of the turbine 3 is drawn into the volute 2, and then discharged from the air outlet of the volute 2 into the guide cavity 5, and then flows back to the environment through the air outlet pipe 6.

[0021] In the present invention, the air guide box 4 is composed of an annular box body and an annular box cover, the annular box body is fixedly sleeved on the outer circumferential surface of the volute 2, the flow guide cavity 5 passes through the end of the annular box body facing away from the motor 1, and the annular box cover is fixed to the end of the annular box body facing away from the motor 1 and covers the flow guide cavity 5. A plurality of mounting holes 41 are provided on the annular box cover, and a plurality of slide plates 42 are slidably mounted on the annular box cover.

[0022] An arc-shaped partition 7 is coaxially arranged in the flow guide cavity 5, one end of the partition 7 is connected and fixed to one end of the annular box body close to the motor 1, and the other end is against the annular box cover, and a gap is left between the partition 7 and the arc-shaped cavity wall surface of the flow guide cavity 5 close to the volute 2, and a gap is left between the partition 7 and the arc-shaped cavity wall surface of the flow guide cavity 5 away from the volute 2, so that the air entering the flow guide cavity 5 from the air outlet of the volute 2 is divided into two streams under the action of the partition 7, and then re-merges into one stream around the entrance of the air outlet pipe 6. The partition 7 is provided with a plurality of notches 1 71 facing the volute 2 and a plurality of notches 2 72 facing away from the volute 2 at intervals along the bending direction, the number of notches 1 71 and notches 2 72 is the same, and the plurality of notches 1 71 and the plurality of notches 2 72 are alternately distributed. Flow control component 1 and flow control component 2 are installed in recess 1 71 and recess 2 72 respectively, and dust collecting filter element 10 is installed in both flow control component 1 and flow control component 2; during the flow process, the two air streams pass through multiple recesses 1 71 and multiple recesses 2 72 in sequence, and are filtered and collected by the corresponding dust collecting filter elements 10 respectively.

[0023] It should be noted that in order to ensure the dust removal effect for each stream of air and avoid the problem of dust removal operation interruption caused by the replacement of the dust collecting filter 10, at least two recesses 71 and two recesses 72 are provided, so that for any stream of air, after any one of the multiple dust collecting filters 10 corresponding to the stream of air is taken out, there is still at least one dust collecting filter 10 to remove dust from the air.

[0024] The multiple mounting holes 41 are respectively connected to the multiple recesses 71 and the multiple recesses 72; the dust filter element 10 is inserted into the flow control component 1 or the flow control component 2 through the mounting holes 41; by sliding the slide plate 42 onto the dust filter element 10, the dust filter element 10 can be prevented from falling out of the mounting holes 41.

[0025] A plurality of drive devices 14 are installed at one end of the air guide box 4 facing the motor 1, and the drive devices 14 are used to drive the flow control component 1, the flow control component 2 and the dust filter 10 to operate. The number of the drive devices 14 is the same as the number of the notches 71 or is twice the number of the notches 71. If the number of the drive devices 14 is different, the cooperation mode of the drive devices 14 with the flow control component 1, the flow control component 2 and the dust filter 10 is also different, as follows: When the number of the driving devices 14 is consistent with the number of the notches 71, one driving device 14 is transmission-connected to one flow control component 1 and one flow control component 2, and corresponds to two dust collecting filter elements 10 installed in the aforementioned flow control component 1 and flow control component 2; When the number of the driving devices 14 is twice the number of the recesses 71 , one driving device 14 is transmission-connected to one flow control component 1 or one flow control component 2, and the transmission connection corresponds to one dust collecting filter element 10 .

[0026] It should be noted that the flow control component 1 and the flow control component 2 which are connected by the same driving device 14 are adjacent to the partition 7 and are respectively located on both sides of the partition 7 .

[0027] The flow control component 1 and the flow control component 2 both have an open state and a closed state. In the open state, the air in the recess 1 71 passes through the flow control component 1 and then is discharged from the recess 1 71 , and the air in the recess 2 72 passes through the flow control component 2 and then is discharged from the recess 2 72 . In the closed state, the air in the recess 1 71 is directly discharged from the recess 1 71 , and the air in the recess 2 72 is directly discharged from the recess 2 72 .

[0028] The dust collecting filter element 10 has a dust collecting state and a replacement state. In the dust collecting state, air passes through the dust collecting filter element 10, and dust in the air is filtered and adsorbed by the dust collecting filter element 10; in the replacement state, the dust collecting filter element 10 can be pulled out of the mounting hole 41.

[0029] When in use, the driving device 14 switches the flow control component 1 and / or the flow control component 2 between an open state and a closed state, and after the flow control component 1 and / or the flow control component 2 are switched to the closed state, the corresponding dust collecting filter element 10 is switched from the dust collecting state to the replacement state; after the dust collecting filter element 10 is switched from the replacement state to the dust collecting state, the driving device 14 switches the corresponding flow control component 1 and / or the flow control component 2 from the closed state to the open state.

[0030] Since during the dust removal process, the dust on each dust filter 10 increases faster as the dust filter 10 is closer to the air outlet of the volute 2, that is, the dust filter 10 closer to the volute 2 should be replaced earlier, the process of the state change of the flow control component 1, the flow control component 2 and the dust filter 10 is as follows: Before collecting dust from the air, the multiple flow control components 1 and the multiple flow control components 2 are all in an open state, and the multiple dust collection filters 10 are all in a dust collection state; when collecting dust from the air, as the motor 1 continuously drives the turbine 3 to rotate, the air around the air inlet of the volute 2 is driven by the turbine 3 to continuously enter the guide cavity 5 through the air outlet of the volute 2, and the two air streams located on both sides of the partition 7 enter and exit the multiple flow control components 1 and the multiple flow control components 2 in sequence, and are continuously dusted by the corresponding multiple dust collection filters 10; When the dust filter element 10 that needs to be replaced is removed, the corresponding flow control component 1 and / or the corresponding flow control component 2 are first switched to a closed state through the driving device 14, and then the dust filter element 10 that needs to be replaced is switched to a replacement state through the driving device 14, and then the slide plate 42 corresponding to the dust filter element 10 in the replacement state is slid away from the dust filter element 10, and then the dust filter element 10 is pulled out of the mounting hole 41; then, a new dust filter element 10 that can be used for dust removal again is inserted from the mounting hole 41, and then it is put into the dust collecting state, and then the slide plate 42 is slid until it contacts the dust filter element 10, and the corresponding flow control component 1 and / or the corresponding flow control component 2 are switched to an open state through the driving device 14.

[0031] Furthermore, if Figure 4 , Figure 5 and Figure 6 As shown, the flow control component 1 includes a flow control tube 8 and a flow control plate 73 which are sequentially arranged along the air flow direction in the guide cavity 5, and the flow control plate 73 is fixed on the partition 7; a gap is left between the flow control plate 73 and the arc-shaped cavity wall of the guide cavity 5 close to the volute 2, and a window 75 for air to pass through is arranged on the flow control plate 73, and the air entering the recess 71 is discharged from the recess 71 through the aforementioned gap or window 75; an opening 11 as an air outlet and capable of cooperating with the window 75 is provided on the flow control tube 8, and an opening 12 as an air inlet is provided on the flow control tube 8; the air in the recess 71 can enter the flow control tube 8 through the opening 12, and be discharged from the flow control tube 8 through the opening 11.

Specifically: When the baffle plate 81 contacts the arc-shaped wall of the flow guiding cavity 5, the gap between the flow control plate 73 and the arc-shaped wall of the flow guiding cavity 5 is blocked by the baffle plate 81, the opening 11 is connected with the window 75, and the opening 12 is open, so that the opening 12 flow control tube 8, the opening 11 and the window 75 form an air channel, and the air entering the recess 71 is discharged from the recess 71 through the channel; When the baffle 81 is separated from the arc-shaped cavity wall of the guide cavity 5, the opening 11 is staggered with the window 75, and the opening 11 and the opening 2 12 are respectively closed by the flow control plate 73 and the partition 7, so that the air entering the recess 71 is directly discharged from the recess 71 through the gap between the flow control plate 73 and the arc-shaped cavity wall of the guide cavity 5.

[0034] A baffle plate 91 is fixed on the outer wall of the flow control tube 9, and the baffle plate 91 contacts and cooperates with the arc-shaped cavity wall surface of the flow guide cavity 5 away from the volute 2. Specifically: When the baffle plate 91 contacts the arc-shaped wall of the flow guiding cavity 5, the gap between the flow control plate 74 and the arc-shaped wall of the flow guiding cavity 5 is blocked by the baffle plate 91, the opening 11 is connected with the window 75, and the opening 12 is open, so that the opening 12 flow control tube 8, the opening 11 and the window 75 form an air channel, and the air entering the recess 72 is discharged from the recess 72 through the channel; When the baffle plate 91 is separated from the arc-shaped cavity wall of the guide cavity 5, the opening 11 is staggered with the window 75, and the opening 11 and the opening 12 are respectively closed by the flow control plate 74 and the partition 7, so that the air entering the recess 72 is directly discharged from the recess 72 through the gap between the flow control plate 74 and the arc-shaped cavity wall of the guide cavity 5.

[0035] Furthermore, if Figure 1 and Figure 7 As shown, one end of the flow control tube 1 8 and one end of the flow control tube 2 9 are respectively fixed to the turntable 1 82 and the turntable 2 92. The turntable 1 82 and the turntable 2 92 both penetrate and rotate to connect one end of the air guide box 4 toward the motor 1. The outer circumferential surfaces of the turntable 1 82 and the turntable 2 92 located outside the air guide box 4 are respectively provided with driving grooves 13. The driving grooves 13 include an oblique guide groove 131 and a straight guide groove 132. The distances from the oblique guide groove 131 and the straight guide groove 132 to the air guide box 4 are shortened successively, and the straight guide groove 132 is parallel to the central axis of the turntable 1 82 and the central axis of the turntable 2 92. The inclination directions of the oblique guide grooves 131 on the turntable 1 82 and the turntable 2 92 are opposite.

[0036] Furthermore, if Figure 4 and Fig.12As shown, the driving device 14 includes a driving frame 141, a driving rod 142 and a driving unit 145.

The driving unit 145 is any one of an electric push rod, a cylinder and a hydraulic cylinder. One or two driving rods 142 are fixed on the driving frame 141, and the driving rods 142 are arranged in a one-to-one matching manner with the driving groove 13; when the driving rod 142 is located in the oblique guide groove 131 and moves relative to the air guide box 4 along the axial direction of the air guide box 4, the turntable 1 82 or the turntable 2 92 rotates; when the driving rod 142 is located in the straight guide groove 132 and moves relative to the air guide box 4 along the axial direction of the air guide box 4, the turntable 1 82 or the turntable 2 92 is stationary.

The rotating rod 103 is coaxially fixed to one end of the connecting plate 1022 away from the connecting column 1023. When the core frame 102 is inserted into the mounting hole 41, the connecting plate 1022 passes through the mounting hole 41 and moves between the opening 11 and the opening 2 12, and the rotating rod 103 passes through the turntable 1 82 or the turntable 2 92, so that the cover plate 1021 is inserted into the mounting hole 41 and closes the mounting hole 41. After the cover plate 1021 moves into position in the mounting hole 41, the slide plate 42 is slid onto the cover plate 1021 to position the cover plate 1021 in the mounting hole 41.

[0041] The filter element 101 is located between a plurality of connecting columns 1023, and the air inlet of the filter element 101 is connected with the second opening 12 via a gap between two adjacent connecting columns 1023, and the air outlet of the filter element 101 is connected with the first opening 11 via a flow channel provided between the connecting plate 1022 and the rotating rod 103; the air entering the flow control tube 1 8 or the flow control tube 2 9 from the second opening 12 enters the filter element 101 through the gap, and penetrates from the outside to the inside into the air outlet inside the filter element 101, and then is discharged through the flow channel and the first opening 11.

[0042] like Fig. 9 As shown, the filter element 101 is cylindrical and hollow as a whole, and a plurality of annular dust collecting grooves are arranged on the outer circumferential surface of the filter element 101, and the plurality of dust collecting grooves are evenly spaced along the axial direction of the filter element 101. The integrated groove serves as the air inlet of the filter element 101 and is connected to the gap between two adjacent connecting columns 1023. The internal cavity of the filter element 101 serves as the air outlet of the filter element 101 and is connected to the flow channel. When the filter element 101 is located in the core frame 102, the two ends of the filter element 101 are sealed with the cover plate 1021 and the connecting plate 1022 respectively; when the air passes through the filter element 101, the dust filtered out by the filter element 101 is collected in the dust collecting groove.

[0043] Furthermore, if Figure 8 , Fig. 9 and Fig.12 As shown, the driving device 14 includes one or two top blocks 143, which are mounted on the driving frame 141, and the top blocks 143 are arranged in a one-to-one matching manner with the adjustment column 107; specifically: When the number of the driving devices 14 is twice the number of the notches 71 , each driving device 14 includes only one driving rod 142 ; when the number of the driving devices 14 is the same as the number of the notches 71 , each driving device 14 includes two driving rods 142 .

[0044] One end of the adjusting column 107 coaxially passes through the rotating rod 103 and cooperates with the top block 143, and the other end of the adjusting column 107 coaxially passes through the core frame 102 and the air outlet of the filter element 101, and cooperates with the indicator component on the core frame 102 for displaying the state of the dust collecting filter element 10; The indicating assembly includes a boss 105, a spring column 1051, a rotating disk 106 and a handle 1061; the boss 105 is fixed to one end of the cover plate 1021 away from the connecting column 1023, and two spring columns 1051 are embedded on the boss 105; the distances between the two spring columns 1051 and the core frame 102 increase successively, and the movable ends of the two spring columns 1051 are alternately embedded in the adjusting column 107; the rotating disk 106 is rotatably sleeved on the boss 105, and a handle 1061 is installed on the rotating disk 106 through an axis rotation; the handle 1061 can be clamped on the spring column 1051 away from the core frame 102 and contact the adjusting column 107. The state change of the dust filter element 10 is indicated by the relative position change between the handle 1061 and the spring column 1051, the rotating disk 106 and the adjusting column 107, specifically: When the handle 1061 is inserted into the spring column 1051 far from the core frame 102, the handle 1061 and the turntable 106 are parallel to each other, the adjustment column 107 is inserted into the spring column 1051 close to the core frame 102 and forms a plane contact with the handle 1061, and the dust filter element 10 is in a dust collecting state; When the handle 1061 is separated from the spring column 1051 away from the core frame 102, the adjustment column 107 is clamped on the spring column 1051 away from the core frame 102, the handle 1061 is tilted with the turntable 106 and the adjustment column 107, and the dust filter element 10 is in a replacement state.

[0045] The process of switching the dust filter element 10 from the dust collecting state to the replacement state by the driving device 14 is as follows: First, the driving rod 142 moves in the inclined guide groove 131 and toward the air guide box 4, pushing the top block 143 toward the adjusting column 107 until it contacts the adjusting column 107. Then, the driving rod 142 moves in the straight guide groove 132 and toward the air guide box 4, so that the top block 143 moves and pushes the adjusting column 107 toward the mounting hole 41, so that the adjusting column 107 pushes the handle 1061 to swing and disengage from the spring column 1051, so that the handle 1061 is transformed from being parallel to the turntable 106 to being inclined to the turntable 106 and the adjusting column 107, until the adjusting column 107 is clamped onto the spring column 1051 away from the core frame 102.

[0046] When the driving rod 142 moves away from the air guide box 4 , the top block 143 is separated from the adjusting column 107 and moves away from the adjusting column 107 .

[0047] It should be noted that after the cover plate 1021 is installed and the mounting hole 41 is sealed, the handle 1061 is swung to be parallel to the turntable 106, and in this process, the adjustment column 107 is pushed to move toward the top block 143, so that the handle 1061 and the adjustment column 107 are respectively clamped onto the two spring columns 1051, and the dust filter element 10 is adjusted to the dust collecting state.

[0048] It should be noted that, since the dust filter element 10 is adjusted to the replacement state by moving the top block 143 to the air guide box 4, the dust filter element 10 is adjusted to the dust collection state by pushing the adjustment column 107 to move by the handle 1061, and the driving rod 142 is moved away from the air guide box 4 only after the dust filter element 10 is switched to the integrated state, the top block 143 should be movably mounted on the driving frame 141. Specifically, the top block 143 and the driving frame 141 cooperate as follows: The top block 143 passes through and is slidably arranged on the driving frame 141. The driving frame 141 is provided with a spring column 144 corresponding to the top block 143 one by one. Two grooves are provided on the top block 143. The distances between the two grooves and the air guide box 4 gradually increase, and the two grooves are alternately matched with the movable ends of the spring column 144.

[0049] During the process of the driving frame 141 moving toward the air guide box 4 to adjust the dust filter 10 to the replacement state, the top block 143 is sleeved on the spring column 2 144 through the groove away from the air guide box 4 and moves with the driving frame 141; during the process of the adjusting column 107 moving to adjust the dust filter 10 to the dust collecting state, the adjusting column 107 pushes the top block 143 to move relative to the driving frame 141 until the top block 143 is sleeved on the spring column 2 144 through the groove close to the air guide box 4.

[0050] Furthermore, if Figure 1 As shown, two shields 18 are commonly clamped on the motor 1 and the second drive unit 17, and the shields 18 are fixedly connected to the air guide box 4. The two shields 18 are spliced ​​into a cylindrical structure, and cover the drive device 14, the third gear 15, the fourth gear 16, the bracket 19, the turntable 1 82 and the turntable 2 92. When the top block 143 moves away from the air guide box 4 with the drive frame 141, the top block 143 will move to contact the shield 18, and move relative to the drive frame 141 again when the drive frame 141 continues to move away from the air guide box 4, until it is clamped on the second spring column 144 again through the groove away from the air guide box 4.

[0051] As a further explanation of the above technical scheme, the above technical scheme divides the air in the guide chamber 5 into two parts through the partition 7, and both air streams are filtered and dust-removed by multiple dust filter elements 10, thereby realizing non-stop replacement of the dust filter element 10, ensuring the uninterrupted air dust removal operation, and the position state of the handle 1061 relative to the turntable 106 can be used to determine when the dust filter element 10 needs to be replaced. At the same time, the handle 1061 facilitates the replacement of the dust filter element 10. However, the dust collecting groove on the filter element 101 for collecting dust will gradually be exposed to the air outside the device during the process of being pulled out from the mounting hole 41, and the dust in the dust collecting groove will escape into the air outside the device due to sliding during the extraction process and the vibration of the device, thereby polluting the air. Therefore, a protective component for preventing the dust in the dust collecting groove from escaping into the air outside the device again is provided on the dust filter element 10.

[0052] The protection component includes a plurality of movable plates 104 arranged on the core frame 102 at positions corresponding to the air inlet of the filter element 101. The plurality of movable plates 104 are distributed in a circular array with the filter element 101 as the center, and the plurality of movable plates 104 correspond one-to-one to the positions of the plurality of connecting columns 1023. A rotating shaft 1041 is fixed at one end of the movable plate 104, and both ends of the rotating shaft 1041 pass through and rotate to connect the core frame 102; the swing of the rotating shaft 1041 drives the movable plate 104 to open and close the gap between two adjacent connecting columns 1023, thereby realizing the closing and opening of the air inlet of the filter element 101.

[0053] Furthermore, a gear 1042 is fixed on the rotating shaft 1041, and the gear 1042 is meshed with the rotating disk 106; the rotating disk 106 is driven to swing by the handle 1061, so that the gear 1042 swings, thereby realizing the swing of the movable plate 104; more specifically: When the connecting plate 1022 is inserted between the opening 11 and the opening 2 12, the handle 1061 is swung around the boss 105, driving the turntable 106 to swing around the boss 105 and causing the plurality of gears 1042 to swing simultaneously and in the same direction, causing the plurality of movable plates 104 to swing simultaneously, opening the air inlet of the filter element 101. Then, the handle 1061 is swung to be parallel to the turntable 106 and is clamped on the spring column 1051, so that the air inlet of the filter element 101 remains in the open state. When the air inlet of the filter element 101 is opened, the position states of the movable plates 104 are as shown in FIG. Fig.13 As shown; When the handle 1061 is pushed out of the spring column 1051 by the adjustment column 107, the handle 1061 is rotated to make the multiple movable plates 104 swing at the same time to close the air inlet of the filter element 101; the position state of each movable plate 104 when the air inlet of the filter element 101 is closed is as shown in FIG. Fig.14After the air inlet of the filter element 101 is closed, the slide plate 42 is slid away from the cover plate 1021 , and the entire dust filter element 10 is pulled out through the mounting hole 41 by the handle 1061 .

[0054] The air inlet of the filter element 101 is closed by multiple movable plates 104 , that is, multiple dust collecting grooves are closed by multiple movable plates 104 , so that dust in the dust collecting grooves can be prevented from escaping during the process of pulling out the dust collecting filter element 10 .

[0055] Furthermore, if Figure 1 and Fig.12 As shown, a gear 2 108 is rotatably sleeved on the outer surface of the adjustment column 107 located in the rotating rod 103, and the teeth of the gear 2 108 are embedded in the rotating rod 103 and slidingly cooperate with the rotating rod 103, and part of the gear 2 108 can move to the side of the motor 1 to expose the rotating rod 103; a gear 3 15 is rotatably sleeved on the motor 1 through the bracket 19 for driving the gear 2 108 to rotate.

[0056] Gear three 15 is composed of an inner meshing gear ring and an outer meshing gear ring that are coaxially fixed together. The outer meshing gear ring is meshed with gear two 108. The inner meshing gear ring is meshed with gear four 16. Gear four 16 is fixed to the output end of drive unit two 17. Drive unit two 17 is a servo motor and is fixed to the housing of motor 1.

[0057] The plurality of rotating rods 103 are driven to rotate by the driving unit 2 17, the gear 4 16, the gear 3 15 and the plurality of gear 2s 108, so that the plurality of dust collecting filter elements 10 rotate simultaneously, so as to facilitate the plurality of filter elements 101 to filter and remove dust from the air, thereby improving the filtering and dust removal effect on the air.

[0058] Gear two 108 moves with the axial movement of the adjusting column 107, that is, when the top block 143 pushes the adjusting column 107 to be clamped on the spring column one 1051 away from the core frame 102, the gear two 108 is synchronously retracted into the rotating rod 103 and disengaged from the gear three 15; when the handle 1061 pushes the adjusting column 107 to be clamped on the spring column one 1051 close to the core frame 102, part of the gear two 108 is exposed from the rotating rod 103 and engages with the gear three 15.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
