Description
Technical field
The present invention relates to technical field of sewage, and in particular to a kind of rotary grilling trash remover of sewage water filtration.
Background technique
The isolation technics of solvent pollutant, which does not refer to, is separated and is removed undissolved in sewage suspend admittedly by physical action
The method of body (including oil film, oil product), is commonly referred to as solid- liquid separation.Equipment used is mostly fairly simple, easy to operate, uses
It is extremely wide.During solid- liquid separation, the principle being related to by it can be divided into two major classes：One kind is that liquid phase is restricted, and is consolidated
Body particle can the free movement in suspension, centrifugal sedimentation, gravitational settling or flotation etc. can be ranged；Another kind of is benefit
It with medium, is restricted solid particle and liquid phase is allowed to pass through medium, sieving retention, filtering etc. can be ranged.It returns
Rotatable grid sewage-removing machine is a kind of special equipment for waste water treatment that can continuously intercept automatically and remove various shape sundries in fluid,
It can be widely used in municipal sewage treatment.Water supply industry, power plant's water inlet, at the same can also be used as weaving, food processing,
Prime screening plant in the industry wastewater treatment process such as papermaking, leather, be the state-of-the-art solid-liquid sieving device in current China it
One.Grilling trash remover is to be assembled into one group of rotary grid chain by a kind of unique tooth harrow factory.Under the driving of motor reducer, tooth
It harrows chain and carries out inverse water (flow) direction rotary motion.When tooth harrow chain runs to the top of equipment, due to the guiding of sheave and bending track, make every
Generation is opposite dynamic from clearing between group tooth harrow, and most solid matters are fallen by gravity.Another part then relies on sweeper
Counter motion cleans up the sundries being sticked on tooth harrow.
Existing rotary grilling trash remover has the following problems：Since there are a large amount of plastic garbages in sewage, clear
Plastic garbage hangs over and will not remove counter motion on tooth harrow during reason, causes to damage tooth harrow, tooth harrow deformation, and reduces
The service life of grid maker；The prehensile sundries of plastic convenient bag, snakeskin bag, water plant etc is easily wrapped on tooth harrow and crossbeam
It is difficult to voluntarily fall off, manually be removed after need to often shutting down, working efficiency is low, is easy to produce failure, maintenance difficult；A large amount of floating materials with
Water enters follow-up pool body, and certain influence can be generated on equipment, and failure of pump, the blender fluidised form of such as diving under water are undesirable.
Summary of the invention
The technical problem to be solved by the present invention is to：Existing rotary grilling trash remover, the plastics rubbish in scale removal process
Rubbish hangs on tooth harrow not easy-clear, causes to damage tooth harrow, tooth harrow deformation, the present invention provides the sewage water filtrations to solve the above problems
Rotary grilling trash remover.
The present invention is achieved through the following technical solutions：
The rotary grilling trash remover of sewage water filtration, including rack, rack are axially located at subsea end equipped with filtering grid, rack
On be additionally provided with the transmission chain driven by motor reducer, the transmission chain drives tooth harrow mechanism rotary motion, the tooth harrow mechanism
Including fixing axle, clearance fit is arranged with sleeve in the fixing axle, sleeve on inner wall at longitudinal central portion circumferentially
Equipped with annular groove, the internal diameter of annular groove is greater than the internal diameter of sleeve, is greater than the reset spring of sleeve diameter in annular groove equipped with outer diameter, resets bullet
Spring is set in fixing axle, and axial one end of reset spring is connect with sleeve lining, the axial other end and fixing axle outer wall connect
It connects；It is equipped with the first locating slot on the sleeve lining of annular groove axial sides, is arranged on the outer wall of fixing axle and described
The sealing ring of a positioning groove adaptation；Sleeve outer wall is equipped with tooth harrow.
Working principle of the present invention is：Sleeve is set in fixing axle, since sleeve lining and fixing axle outer wall gap are matched
It closes, then fixing axle and sleeve can relatively rotate movement；It will open up and buffered dedicated for accommodating reset spring on sleeve lining,
Due to being connected again by reset spring between sleeve lining and fixing axle outer wall, it is twined simultaneously in plastic garbage goods water plant etc.
When being wound on tooth harrow and grid, the effect of tooth harrow under tension makes the rotational motion of the relatively fixed axis generation certain angle of sleeve, directly
Plastics or the water plant of winding are detached to tooth harrow, at this point, sleeve resets tooth harrow relative to the rotation of fixed axis under action of reset spring
Continue cleaning operation, tooth harrow can be effectively prevent to deform.By the way that sealing ring and are arranged at axial ends in fixing axle
A positioning groove adaptation, can be used rubber seal, while playing good sealing waterproof action by rubber seal, also rises
