Embodiment
Below in conjunction with the accompanying drawings, technical scheme is described in detail.
As shown in Figures 1 to 4, a kind of anti-blocking crusher of the embodiment of the present invention, including driving device 1, rack 2, two
A rotary drum 5 and two milling cutters 6.Rotary drum 5 and milling cutter 6 are rotatably connected in rack 2 respectively；Driving device 1 respectively with rotary drum 5 and
Milling cutter 6 connects, and drives rotary drum 5 and milling cutter 6 to rotate；Milling cutter 6 is between two rotary drums 5；It is adapted between two milling cutters 6.
The crusher of above-described embodiment is installed in water channel, and the dirt in current is crushed.During work, driving device
1 drive rotary drum 5 and milling cutter 6 rotate.Current are flowed through from the gap of rotary drum 5 to crusher, or between rotary drum 5 and milling cutter 6
Flowed through in gap.When dirt small volume, then dirt flows through crusher with current.It is when dirt volume is larger, then dirty
Thing cannot directly flow through crusher.The larger dirt of volume flow to 6 table of milling cutter on 5 surface of rotary drum, and with 5 surface pivots of rotary drum
Face.Since milling cutter 6 also rotates under the action of driving device 1, so the larger dirt of volume is flow between two milling cutters 6.
Under the action of two milling cutters 6, the larger dirt of volume is broken.Dirt after broken is flowed out with water.
As shown in Fig. 2, when water (flow) direction is to flow to crusher from A, under the drive of driving device 1, rotary drum 5 and milling cutter 6
Rotated by the direction of arrow in Fig. 2.Sewage imports crusher 2, the wherein larger solid that cannot be flowed through by 5 gap of rotary drum of volume
Thing, between being retained by rotary drum 5 and be brought into two milling cutters 6, downstream is flowed to after milling cutter 6 is broken.Sewage and wherein small volume
Dirt downstream is flowed to by 5 gap of rotary drum.When water (flow) direction change, as shown in figure 3, when flowing to crusher 2 from B directions, only
The steering of driving device 1 need to be changed, direction rotates as shown in Figure 3 for rotary drum 5 and milling cutter 6, and crusher can normal use.In this way,
No matter current come from which direction stream, can be worked normally using the crusher of the present embodiment, without replacing crusher.
As preference, the anti-blocking crusher of above-described embodiment, further includes two the first deflectors 5 and two second are led
Flowing plate 7.First deflector 5 and the second deflector 7 are connected in rack 2, and two the first deflectors 5 are located at 2 side of rack,
Two the second deflectors 7 are located at 2 opposite side of rack., will when crusher is installed on water channel to cause current to enter in crusher
Deflector 7 and the side wall of water channel offset.In this way, current are by the first deflector 5 or the water conservancy diversion of the second deflector 7, into broken
In broken machine.Since water (flow) direction may change, so setting the first deflector 5 and the second deflector 7, the two of crusher is laid in
Side.Regardless of water (flow) direction, external water stream is oriented to two by two the first deflectors 5 or two the second deflectors 7 and is turned
In drum 5.
In the present embodiment, the rotation direction of milling cutter 6 is to enter dirt from dirt to flow out direction.As shown in Fig. 2, current from
A comes to stream, and dirt also comes from A to stream.Milling cutter 6 positioned at the left side rotates clockwise, and the milling cutter 6 positioned at the right rotates counterclockwise.
Under the action of two milling cutters 6, by smashing sewages.As shown in figure 3, current come from B to stream, dirt also comes from B to stream.Positioned at the left side
Milling cutter 6 rotate counterclockwise, the milling cutter 6 positioned at the right rotates clockwise.Under the action of two milling cutters 6, by smashing sewages.It is described
The rotation direction of rotary drum 5 and the rotation direction of the milling cutter 6 adjacent with the rotary drum 5 are identical.In this way, rotary drum 5 rotates, it will be located at
On the larger dirt of volume turn on milling cutter 6, in favor of broken.The larger dirt of so-called volume, referring to cannot be by turning
The dirt of the gap outflow of drum 5.
As preference, the anti-blocking crusher further includes guide rail 3, and guide rail 3 is connected to the both sides of rack 2.Pass through
Guide rail 3 is set, is conducive to fast positioning crusher.The mounting fixing parts on pool wall, when installing fixed crusher, by 3 He of guide rail
Fixing piece is adapted to.For example, guide rail 3 is embedded in fixing piece from the top down.
As preference, the driving device 1 is located at the top of rack 2.Driving device 1 is located at rack 2, easy to regulate and control
Rotation direction.The crusher of the present embodiment can be suitable for the smashing sewages of former and later two water (flow) directions.By varying rotary drum 5,
The rotation direction of milling cutter 6 so that crusher can carry out break process to the dirt in current, broken without replacing
Machine.
In addition, the crusher of the present embodiment has automatic cleaning function, it is more unobstructed to cross water, it is not necessary to manual cleaning.When
Crusher was stopped transport after a period of time, it may occur that dirt blocks.At this time, by 1 alternate change direction of rotation of driving device, then turn
Drum 5 and the rotation of 6 alternating direction of milling cutter, block object and are gradually torn cut-out, and then flow to downstream by milling cutter 6.Preferably, drive
Dynamic device is motor, by varying power positive cathode, thus it is possible to vary the rotation direction of motor.It is real by the switching of rotation direction
The automatic cleaning of dirt is showed.
The crusher of the embodiment of the present invention can realize two-way water flowing, and same channel not only can be with dry season diversion, but also can be with
Rainy season draining, and only need to change power positive cathode, you can realize the switching of rotation direction, realize two-way water flowing.
The basic principles, main features and advantages of the invention have been shown and described above.Those skilled in the art should
Understand, the present invention from above-mentioned specific embodiment limitation, the description in above-mentioned specific embodiment and specification be intended merely into
One step illustrates the principle of the present invention, without departing from the spirit and scope of the present invention, the present invention also have various change and
Improve, these changes and improvements all fall within the protetion scope of the claimed invention.The scope of protection of present invention will by right
Ask book and its equivalent thereof.
