Definitions
- the present invention is related to a dust collecting device separating dust by cyclone, particularly to a dust collecting device using multi-cyclone dust filtration.
- cyclone separation is one kind of centrifugal sedimentation, in which centrifugal force is used to rotate particles at high speed in an eddy airflow. The higher the rotational speed is, the higher centrifugal sedimentation velocity the particles obtain. Further, the object of separating the particles from the airflow is then achieved.
- a conventional cyclone separator as schematically illustrated in Fig. 1 , is mainly composed of a separation cylinder 8.
- the separation cylinder 8 is provided through the wall surface thereof with an air inlet 81, is tapered in the tube diameter thereof toward the bottom, and is provided at the top thereof with an extracting channel 82.
- the dust filtration effect of the conventional cyclone separator is considerably limited. If the enhancement of the dust filtration effect of the cyclone separator is desired, there are mainly two ways of implementation as follows: one is an increased volume of chamber within the separation cylinder, and the other is a multi-layered dust filtering inner cylinder provided within the separation cylinder, as disclosed in the patents Nos.

- the first cyclone is incapable of entering the return flow tube from the dust filtration channel due to the restriction provided by the airflow guiding bonnet.
- the second cyclone is allowed to flow toward the exhaust port. As passing by the dust filtration channel, the second cyclone is capable of throwing dust contained therein into the dust filtration channel. The dust is restricted by the airflow guiding bonnet so as to enter the dust collecting chamber.
- the airflow guiding component is provided with a drainage tube connecting the airflow guiding bonnet to the exhaust port.
- the airflow guiding component is provided with an auxiliary airflow guiding bonnet, which is provided for the return flow tube and allowed for forming, together with the airflow guiding bonnet, the dust filtration channel.

Further, each of the supporting ribs is provided with a windward end and a discharge end along the flow direction of the first cyclone, each supporting rib being provided in an inclined manner, the windward end being higher than the discharge end in position.
- an outer diameter of the return flow tube is smaller than an inner diameter of the annular side wall.
- the cyclone chamber is provided with a first spatial width, while the dust collecting chamber is provided with a second spatial width greater than the first spatial width. Further, each of the dust collecting chamber and the cyclone chamber is formed by a housing, respectively.
- first and second used for elements are meant to distinguish the elements from each other, and not used for limiting the sequential order thereof.
- relative spatial expressions including “top end”, “bottom edge”, “upward”, “downward” and so on., mentioned hereinafter are determined on the basis of orientation drawn in the drawings of the context. It should be understood that the relative spatial expressions may be varied along with the change of orientation drawn in the drawings. For instance, the original “top end” and “bottom edge” may be varied as “left” and “right”, respectively, once the drawings are rotated to horizontal.
- the present invention provides a dust collecting device 100 using multi-cyclone dust filtration, the dust collecting device 100 possibly being applied to an industrial process obtaining pure working gas necessarily.
- the dust collecting device 100 includes a dust collecting chamber 11, a cyclone chamber 12 and an airflow guiding component 13.
- the dust collecting chamber 11 is connected to the cyclone chamber 12, the cyclone chamber 12 having a first spatial width 120, while the dust collecting chamber 11 having a second spatial width 110 greater than the first spatial width 120.
- the first spatial width 120 is directed to a spatial length in the cyclone chamber 12, while the second spatial width 110 is directed to a spatial length in the dust collecting chamber 11.
- each of the cyclone chamber 12 and the dust collecting chamber 11 is formed by a housing (15, 16), respectively; that is to say, each of the cyclone chamber 12 and the dust collecting chamber 11 is subordinate to different housings (15, 16), respectively.
- the two housings (15, 16) are combined through a connecting structure, the connecting structure possibly being selected from a screwing element, a fastening element and so on. Accordingly, an operator is allowed to separate the two housings (15, 16) so as to clean the dust collecting chamber 11 depending on the state of dust collection of the dust collecting device 100.
- the housing 16 forming the dust collecting chamber 11 may be further a dust collecting barrel.
- the cyclone chamber 12 is provided with an intake port 121, an annular side wall 122 connected to the intake port 121, an engaging port 123 communicated with the dust collecting chamber 11, and an exhaust port 124.
- the intake port 121 is provided on a tangent (as indicated by 125 in Fig. 3 ) to the annular side wall 122.
- the intake port 121 may be joined to a tube.
- the intake port 121 may be further a tubular structure protruding out of the annular side wall 122.
- the intake port 121 is provided at one end of the cyclone chamber 12 away from the dust collecting chamber 11, i.e., the top end of the cyclone chamber 12, while the engaging port 123 is provided at the bottom edge of the cyclone chamber 12.
- the engaging port 123 may be defined by the annular side wall 122.
- the exhaust port 124 is provided at the top end of the cyclone chamber 12.
- the cyclone chamber 12 is provided with a barrier wall 126 provided around the exhaust port 124, the barrier wall 126 being not connected to the airflow guiding component 13, for the reduction of possibility of discharging the gas, entering the cyclone chamber 12 from the intake port 121, via the exhaust port 124 directly.
- a first phantom line 127 may be defined in the extension direction of the intake port 121, while a second phantom line 128 may be defined in the extension direction of the exhaust port 124.
- the first phantom line 127 and the second phantom line 128 are not intersected in the top view from the cyclone chamber 12.
- the second phantom line 128 is extended longitudinally, while the first phantom line 127 is extended laterally.
- the airflow guiding component 13 is provided within the cyclone chamber 12.
- the airflow guiding component 13 is provided with a return flow tube 131 located within the cyclone chamber 12, an airflow guiding bonnet 132 coaxially and separately located with respect to the return flow tube 131, and a dust filtration channel 133 formed between the airflow guiding bonnet 132 and the return flow tube 131.
- an outer diameter 401 of the return flow tube 131 is smaller than an inner diameter 402 of the annular side wall 122, such that a space allowing the flow of cyclone is still provided between the return flow tube 131 and the annular side wall 122.
- the airflow guiding component 13 is provided with a plurality of supporting poles 134 connecting the airflow guiding bonnet 132 to the return flow tube 131.
- each of the plurality of supporting poles 134 is allowed to connect one end of the return flow tube 131 facing toward the airflow guiding bonnet 132 to one side of the airflow guiding bonnet 132 facing toward the return flow tube 131.
- the pattern and actual location of the plurality of supporting poles 134 may be modified appropriately depending on implementation, without being reiterated herein any more.
- the airflow guiding bonnet 132 may be also fixed through the structure disclosed in another embodiment.
- the airflow guiding component 13 is provided with a drainage tube 135 connecting the airflow guiding bonnet 132 to the exhaust port 124.
- the drainage tube 135 and the return flow tube 131 are located coaxially.
- the drainage tube 135, together with the airflow guiding bonnet 132, may be formed as integral structure. Furthermore, the airflow guiding bonnet 132 may be further formed as umbrella-shaped structure. Assuming a portion of the airflow guiding bonnet 132 corresponding to the return flow tube 131 is considered as a top end, the bottom end of the airflow guiding bonnet 132 may face toward the engaging port 123. One side of the dust filtration channel 133 is blocked by the airflow guiding bonnet 132, such that gas coming from the intake port 121 is incapable of entering the dust filtration channel 133. In addition, a portion of the airflow guiding bonnet 132 corresponding to the return flow tube 131 is a vent 136.
- vent 136, the return flow tube 131 and the drainage tube 135 are located on the same axis. Furthermore, after the cyclone chamber 12 and the airflow guiding component 13 of the present invention are combined, a first cyclone path 601 advancing toward the dust collecting chamber 11 along the annular side wall 122 and a second cyclone path 602 being delimited by the return flow tube 131, advancing toward the exhaust port 124 and passing by the dust filtration channel 133 are formed. Additionally, the initial part of the second cyclone path 602 is limited by the return flow tube 131 of the present invention, such that cyclone formed here is compact due to the effect of the return flow tube 131.
- the intake port 121 may be connected to an apparatus, capable of generating a gas to be filtered 300, via a tube, or may be provided within a space filled with the gas to be filtered 300 directly.
- the exhaust port 124 is connected to an air extracting device 200.
- the cyclone chamber 12 is allowed to enter negative pressure state after the air extracting device 200 is started, so as to suck the gas to be filtered 300 into the cyclone chamber 12 via the intake port 121.
- the gas to be filtered 300 is allowed to flow spirally along with the annular side wall 122 after entering the cyclone chamber 12, so as to form a first cyclone 301.
- the first cyclone 301 is allowed to travel downward along the annular side wall 122, and finally enter the dust collecting chamber 11 via the engaging port 123; that is to say, the first cyclone 301 is allowed to advance along the first cyclone path 601. Additionally, the first cyclone 301 is incapable of entering the return flow tube 131 from the dust filtration channel 133 in the process of downward travel due to the restriction provided by the airflow guiding bonnet 132.
- the size of the dust collecting chamber 11 is larger than that of the cyclone chamber 12, such that the rotational speed of the first cyclone 301 is reduced, and meanwhile the dust (for instance, 501 depicted in Fig. 5 ) mingled with the gas to be filtered 300 is separated from the gas to be filtered 300 so as to fall into the dust collecting chamber 11 owing to the effect of the reduction of rotational speed of the first cyclone 301 and the force of gravity of the dust itself. In this way, the primary dust filtration is completed. Furthermore, the air extracting device 200 is not stopped working, in such a way that the gas to be filtered 300 entering the dust collecting chamber 11 is sucked into the return flow tube 131.
- the gas to be filtered 300 is also allowed to flow spirally along the return flow tube 131 immediately and then form a second cyclone 302.
- the dust collected within the dust collecting chamber 11 is not mixed into the second cyclone 302 due to its own weight.
- the speed of the second cyclone 302 is higher than that of the first cyclone 301 significantly due to a tube diameter of the return flow tube 131 being smaller than that of the dust collecting chamber 11, such that a higher centrifugal force may be generated by the second cyclone 302.
- the second cyclone 302 is allowed to advance toward the exhaust port 124 continuously, and then leave the dust collecting device 100 via the exhaust port 124.
- the dusts contained in the gas to be filtered 300 are different in size, such that the larger dust grains may be separated from the gas to be filtered 300 in the primary dust filtration, while the smaller dust grains may be separated from the gas to be filtered 300 in the secondary dust filtration of the dust collecting device 100.
- the filter screen provided for the exhaust port 124 may be eliminated. It is unnecessary for a user to dismantle the dust collecting device 100 several times to replace the filter screen if the filter screen is eliminated, so as to facilitate the use in a working environment where the gas to be filtered 300 includes hazardous gas.
- the airflow guiding component 13 is provided with an auxiliary airflow guiding bonnet 137, which is provided for the return flow tube 131 and allowed for forming, together with the airflow guiding bonnet 132, the dust filtration channel 133.
- the auxiliary airflow guiding bonnet 137 may be extended from an edge, facing toward the airflow guiding bonnet 132, of the return flow tube 131, while the auxiliary airflow guiding bonnet 137 and the airflow guiding bonnet 132 are provided as the same umbrella-shaped structure with an identical pattern.
- each of the auxiliary airflow guiding bonnet 137 and the airflow guiding bonnet 132 is located at one side of the dust filtration channel 133, respectively.
- the dust when thrown by the second cyclone 302, is allowed to advance toward the cyclone chamber 12 along a space between the auxiliary airflow guiding bonnet 137 and the airflow guiding bonnet 132, as depicted in Fig. 12 .
- the airflow guiding component 13 may be provided with a plurality of connecting ribs 144 connecting the airflow guiding bonnet 132 to the auxiliary airflow guiding bonnet 137.
- the plurality of connecting ribs 144 are provided in a spaced manner; that is to say, a space for gas to flow is presented between any two adjacent connecting ribs 144.
- the plurality of connecting ribs 144 are allowed to support the airflow guiding bonnet 132, so as to enable not only separation of the airflow guiding bonnet 132 and the auxiliary airflow guiding bonnet 137, but also non-necessity for the airflow guiding bonnet 132 to obtain support from other members.
- the airflow guiding component 13 is provided with a drainage bonnet 138 provided at one side, facing toward the engaging port 123, of the return flow tube 131 for guiding the gas to be filtered 300 into the return flow tube 131, so as to enable the gas to be filtered 300 to enter the return flow tube 131 more positively.
- a drainage bonnet 138 provided at one side, facing toward the engaging port 123, of the return flow tube 131 for guiding the gas to be filtered 300 into the return flow tube 131, so as to enable the gas to be filtered 300 to enter the return flow tube 131 more positively.
- the drainage bonnet 138 it is possible to provide the drainage bonnet 138 at an edge, facing toward the engaging port 123, of the return flow tube 131.
- the pattern of the drainage bonnet 138 is identical to that of the airflow guiding bonnet 132.
- a port, connected to one end of the return flow tube 131, of the drainage bonnet 138 is smaller than the other port, far away from the return flow tube 131, of the drainage bonnet 138 in diameter.
- the drainage bonnet 138 is not necessary to be provided at the edge, facing toward the engaging port 123, of the return flow tube 131, but is only necessary to be provided at one side, close to the engaging port 123, of the return flow tube 131.
- the return flow tube 131 is provided, at one side close to the engaging port 123 thereof, with at least one drainage through-hole 139 provided correspondingly to the drainage bonnet 138, in the case that the drainage bonnet 138 is mounted to the side wall of the return flow tube 131, such that the drainage through-holes 139 may enable part of the gas to be filtered 300, which is not allowed to enter the return flow tube 131 from the end thereof and then restricted by the drainage bonnet 138, to enter the return flow tube 131 via the drainage through-holes 139, just as depicted in Fig. 11 .
- the return flow tube 131 is provided with a connecting wall 140 connecting the auxiliary airflow guiding bonnet 137 to the drainage bonnet 138.
- the connecting wall 140 may be provided in parallel with the tube wall of the return flow tube 131.
