Description
Technical field
The utility model is related to sewage treatment fields, more specifically to a kind of fine grid machine.
Background technology
Contain small garbage or fiber-like floating material in water inlet at present, often selects rotary machinery grid.Rotary machinery
Grid is the continuous sewage disposal apparatus for integrating trash rack and trash, based on trash rack, by being incited somebody to action around grid circumversion chain
Rake teeth of removing contamination drives, and the dirt being attached on grizzly bar is taken at the top of trash, completes overturning and unloads dirty action, keeps the cross-section of river
It cleans without dirt, the disadvantage is that：Grid gap is difficult to uniformly, cause water outlet leakage slag rate high；The lower end of grid mechanical part needs
Enough safe distances are reserved, at this location, flow is directed through, and cannot obtain the filtration treatment of grid；Turn round rake teeth by
Chain is strung, all linked with one another, and moving parts is very more, and maintenance load is big；It takes up a large area.
And for MBR membrane treatment process, filtering accuracy higher needs to be higher than 1mm, it is usually required mainly for removes the tiny fibre such as hair removal
Substance is tieed up, avoids result in and occurs quickly to block in membrane module, often rotary drum mechanical grille is selected to be used for front-end processing.Rotary drum machine
The operation principle of tool grid is that sewage is flowed into from the front end of cylindric rotary drum, the grid seam outflow through rotary drum side, the grid in sewage
Slag is then trapped on the grizzly bar on the inside of bulging grid, and liquid level difference reaches before and after the grid slag of rotary drum retention runs up to a certain amount of, grid
Limit value, external drum or inner tine for harrow are rotated with certain speed, same in the cleaning filter tip that rotary drum outer upper is arranged along filter drum overall length
Shi Qidong, flushing water remove grid slag to the spiral conveying groove in grid center, through built-in screw compressor by grid slag pressure
Dehydration is squeezed, is fallen into garbage can, the disadvantage is that：Conveyance capacity is limited；Need high pressure water washing.
Utility model content
Problem to be solved in the utility model is, provides a kind of can effectively reduce and leakage slag phenomenon occurs, sewage passes through
Rate is high, and fine grid machine simple in structure, that floor space is small.
In order to solve the above-mentioned technical problem, the utility model provides a kind of fine grid machine comprising rack, motor, rotation
Shaft, grizzly bar, rake teeth and baffle, the rotary shaft are arranged in the rack, the output end of the motor and the rotary shaft
Connection is evenly spaced apart to be arranged multiple rake teeths along the circumferencial direction of the rotary shaft, and the grizzly bar is equipped with a plurality of and along institute
The axial direction for stating rotary shaft is disposed in an evenly spaced relation on the movement locus of the rake teeth, and forms the tooth of multiple tracks and the rake teeth
The grid slot of item cooperation, when rake teeth rotation, the rake teeth and the grid slot during be cooperated to and detach, the rake teeth
The length that rack is stretched out from the grid slot rotates with the rake teeth and is gradually reduced and is detached from the grid slot, the baffle plate setting
It is detached from the lower section of the position of the grid slot in the rack of the rake teeth and can contact and can scrape described with the end of the rake teeth
Impurity on rake teeth.
As the preferred scheme of the utility model, the spacing between the grizzly bar is 1mm-5mm.
As the preferred scheme of the utility model, the rake teeth is made of plastics.
As the preferred scheme of the utility model, the grizzly bar is made of stainless steel.
A kind of fine grid machine for implementing the utility model has the advantages that compared with prior art：
The rake teeth of the utility model is circled around rotary shaft, and the impurity that rake teeth intercepts passes through mutual crowded between grizzly bar
Pressure, makes impurity be stored in rake teeth end, and when rake teeth end is contacted with baffle, impurity can be scraped by baffle, realized deslagging, be not easy to block up
Grizzly bar is filled in, to improve sewage percent of pass.In addition, grizzly bar spacing is uniform, appearance leakage slag phenomenon is effectively reduced；And its structure letter
Single, occupied space is few, easy to maintenance.
Description of the drawings
In order to illustrate more clearly of the technical solution of the utility model embodiment, the attached drawing of embodiment will be made below simple
Ground introduction.
Fig. 1 is a kind of structural schematic diagram of fine grid machine provided by the utility model.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the preferred embodiment of the utility model, a kind of fine grid machine comprising rack 1, motor 2, rotation
Axis 3, grizzly bar 4, rake teeth 5 and baffle 6, the rotary shaft 3 are arranged in the rack 1, the output end of the motor 2 and the rotation
Shaft 3 connects, and is evenly spaced apart that multiple rake teeths 5 are arranged along the circumferencial direction of the rotary shaft 3, the grizzly bar 4 is equipped with more
Item and along the movement locus that the axial direction of the rotary shaft 3 is disposed in an evenly spaced relation in the rake teeth 5, and form multiple tracks and institute
The grid slot for stating the rack cooperation of rake teeth 5, when the rake teeth 5 rotates, the rake teeth 5 and the grid slot are from being cooperated to the process detached
In, the length that the rack of the rake teeth 5 is stretched out from the grid slot is gradually reduced with the rotation of the rake teeth 5 and is detached from the grid
Slot, the baffle 6 be arranged the rack in the rake teeth 5 be detached from the grid slot position lower section and can be with the end of the rake teeth 5
Portion contacts and can scrape the impurity on the rake teeth 5.
The rake teeth 5 of the utility model is circled around rotary shaft 3 as a result, rake teeth 5 intercept impurity by grizzly bar 4 it
Between mutual extruding, so that impurity is stored in 5 end of rake teeth, when 5 end of rake teeth and baffle 6 contact, impurity can be scraped by baffle 6,
It realizes deslagging, grizzly bar 4 is not easy to plug, to improve sewage percent of pass.In addition, 4 spacing of grizzly bar is uniform, appearance leakage slag is effectively reduced
Phenomenon；And its is simple in structure, occupied space is few, easy to maintenance.
More preferably, the spacing between the grizzly bar 4 is 1mm-5mm, and the gap between grizzly bar 4 is small, can be intercepted more, thinner
Insoluble matter, can be applicable to the front-end processing of MBR membrane treatment process.
More preferably, the rake teeth 5 is made of plastics, and plastics good toughness scrapes the impurity on rake teeth 5 convenient for baffle 6, fortune
Row noise is low, and easy to maintain, and avoids causing to damage to baffle 6.Preferably, rake teeth 5 is made of nylon.
More preferably, the grizzly bar 4 is made of stainless steel, and is improved stability of the grizzly bar 4 on fine grid machine, is not easy to shake.
Above disclosed is only the preferred embodiment of the utility model, certainly cannot be new to limit this practicality with this
The interest field of type, therefore equivalent variations made according to the patent scope of the utility model still belong to the utility model and are covered
Range.
