Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
It should be noted that when element is referred to as " being fixed on " or " being arranged at " another element, it can be directly another
On one element or it is connected on another element.When an element is referred to as " being connected to " another element, it can be with
It is directly to another element or is indirectly connected on another element.
It should also be noted that, the orientation term such as left and right, upper and lower in the present embodiment, be only each other relative concept or
Using the normal operating condition of product as reference, and should not be regarded as restrictive.
As shown in figure 1, the grid device of the present embodiment includes housing 10, sieve plate 20 and chain type grid rake teeth group 30, housing
10 there is the transfer passage for being used for conveying bed mud mud and the operating space that rubbish separation is carried out to bed mud mud, sieve plate 20 to connect
Connect on the housing 10 and in the operating space, the outlet of the upstream face and transfer passage of sieve plate 20 is oppositely arranged with by bed mud mud
The building waste of comparison bulk in slurry, which screens out, to be come and carries out energy dissipating to bed mud mud, and chain type grid rake teeth group 30 is arranged on behaviour
Make in space, chain type grid rake teeth group 30 is located at the underface of sieve plate 20, and chain type grid rake teeth group 30 is moved with by remaining rubbish
Rubbish is separated from bed mud mud.
By setting up sieve plate 20 in the operating space of grid device, come it when bed mud mud is delivered into from transfer passage
Afterwards, bed mud mud is caught by sieve plate 20, so as to reduce the flow velocity of bed mud mud and pressure, and the part body in bed mud mud
The larger rubbish of product is sifted out by sieve plate 20, and then bed mud mud is fallen in chain type grid rake teeth group 30 by the sieve aperture of sieve plate 20 and carried out
Further rubbish lock out operation.Therefore, using the double-layer grating device of the present invention, bed mud mud can not only effectively be reduced
Impact energy and realize energy dissipating, and can simultaneously utilize sieve plate 20 carry out rubbish separation.
With reference to shown in Figure 3, in the present embodiment, grid device includes shunting energy dissipating device 51, shunting energy dissipating device 51 with
Housing 10 is connected, and shunting energy dissipating device 51 is located in the transfer passage of housing 10, and the edge of shunting energy dissipating device 51 with
Have between the inwall of the transfer passage of housing 10 and make the gap that bed mud mud can pass through.When bed mud mud is from transfer passage quilt
Conveying is come in, and the bed mud mud with high flow rate and high pressure is fallen directly on shunting energy dissipating device 51, because bed mud mud is with height
The impact energy of flow velocity and high pressure and shunting energy dissipating device 51, which touch, to be turned, thus shunting energy dissipating device 51 stop bed mud mud so that
Realize energy dissipating.Multiple blades 510 are provided with shunting energy dissipating device 51, and multiple blades 510 are around the center of shunting energy dissipating device 51
Skew ground is set, and now the molded line of each blade 510 can not also pass through pivot by the center.Shunting energy dissipating
Device 51 falls in gap of the bed mud mud dispersedly between its edge and the inwall of transfer passage on sieve plate 20.In addition, in order to
Increase flow of the bed mud mud by shunting energy dissipating device 51, thus multiple through holes have been opened up on shunting energy dissipating device 51, bed mud mud
Slurry in addition to, while can also flow on sieve plate 20 except from marginal gap from these through holes.
As shown in Fig. 2 each grid rake teeth of chain type grid rake teeth group 30 includes the first rake teeth section 31 and the second rake teeth section
32, the first rake teeth section 31 is connected with the second rake teeth section 32, and moving direction of the first rake teeth section 31 along chain type grid rake teeth group 30 prolongs
Stretch to form hook-shaped rake teeth.The flexible rubbish being mingled in bed mud mud is separated using hook-shaped rake teeth, such as plastics
Bag, pig hair etc..As shown in Fig. 2 the side of the second rake teeth section 32 to the threshold value of the first rake teeth section 31 is L, 5cm≤L≤
10cm, it is preferable that distance L is chosen at 6cm to length value between 8cm.
Preferably, each grid rake teeth of chain type grid rake teeth group 30 is laminated structure, and plane where grid rake teeth with
The moving direction of chain type grid rake teeth group 30 is parallel.On one end away from the first rake teeth section 31 of each second rake teeth section 32,
On direction is extended along, the first circular hole 321 and the second circular hole 322 are offered successively, in the movement of chain type grid rake teeth group 30
Multiple rows of grid rake teeth is distributed with direction, adjacent two rows grid rake teeth is arranged alternately, and the first circle of wherein row's grid rake teeth
Second circular hole 322 of hole 321 and another row's grid rake teeth is located on a circular shaft, and multiple rows of grid rake tooth-shaped is into chain structure.
The chain type grid rake teeth group 30 of chain structure carries out constantly circulating movement under the driving of motor, by rubbish from bed mud mud
In separate.
In the present embodiment, sieve plate 20 includes multiple sieve plate pitch chains, is connected turnablely between two neighboring sieve plate pitch chain,
And multiple sieve plate pitch chains are set end to end, so as to form the sieve plate 20 of crawler type (crawler chain type).When bed mud mud from
Transfer passage realizes after the impact energy of bed mud mud is reduced for the first time that bed mud mud flows to sieve by shunting energy dissipating device 51
On plate 20, stopped again by sieve plate 20 and impact energy is reduced.When the bulk rubbish in bed mud mud is divided by sieve plate 20
After electing, caterpillar sieve plate 20 cycle rotation under the driving of motor, so as to which rubbish is transferred out outside grid device
Placed.In order to use the bed mud mud input quantity of larger flow as much as possible, therefore can be by each grid pitch chain
On grid through hole open up enough to big, the barrier separation of building waste that these grid through holes can not only be relatively large comes, simultaneously
It can adapt to the bed mud mud of the big flow of input.The sieve plate 20 of chain type drives rotation main wheel by motor, so as to band
Dynamic chain type grid rake teeth group 30 carries out reciprocation cycle movement.
As shown in figure 1, the rake teeth of chain type grid shown in figure group 30 is driven by three drives, wherein positioned at most lower
The drive of side is tensioning wheel, after chain type grid rake teeth group 30 works longer period of time, chain type grid rake teeth group 30
Length can change, so as to cause chain type grid rake teeth group 30 to be relaxed in the rotating wheel of motor.Therefore, tensioning is utilized
Wheel is tensioned to continue regulation.Chain type grid rake teeth group 30 drives at least through two drives.Certainly, chain type grid rake teeth group
30 only can also be driven by two rotating wheels, and the pivot center of two rotating wheels is located in the same horizontal plane, and its
In a rotating wheel have variable frequency drive motors driving, another rotating wheel is driven pulley.
Both in the present invention, the output end of sieve plate 20 will extend longer than the output end of chain type grid rake teeth group 30, so
The process of output rubbish is not in the rubbish for the output of rubbish interference chain type grid rake teeth group 30 that sieve plate 20 exports.
These are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
All any modification, equivalent and improvement made within principle etc., should be included in the scope of the protection.
