Abstract
The utility model discloses a novel grid for breaking, which comprises a body. A driving device is fixed on the upper surface of the body, and drums, a main cutter unit and an auxiliary cutter unit are mounted in the body. The main cutter unit includes a driving shaft which is connected with the driving device and provided with main cutting blades; and the auxiliary cutter unit includes an auxiliary driving shaft which is provided with auxiliary cutting blades. Besides, a driving gear fixed on the main driving shaft meshes with a driven gear fixed on the auxiliary driving shaft, a bearing carrier is further mounted in the body, and two bearings which are respectively matched with the driving shaft and the auxiliary driving shaft are fixed on the bearing carrier. The novel grid for breaking adopts the double-shaft design, and the cutting blades mounted on the two shafts are in staggered arrangement to realize helical cutting, so that large solid pollutants can be broken thoroughly. Further, particles of the pollutants after being broken are uniform and cannot affect normal running of a blowdown pump.
Description
Technical field:
The utility model relates to breaking type grid sewage-removing machine technical field, specifically a kind of device that bulk solid matter in the liquid is carried out fragmentation.
Background technology:
In the sewage treatment process in city; need use residual sea water pump goes out sewage discharge; but because in the sewage a lot of solid impurity are arranged; if these impurity enter residual sea water pump; return the working efficiency that influences residual sea water pump; even may make that residual sea water pump is damaged; reduce its work-ing life; traditional method is that the front end at residual sea water pump installs the blowdown grid additional; the solid pollutant that volume is bigger is kept apart; play similar filtering effect, be used for protecting residual sea water pump, weak point is also arranged but do like this:
1) after traditional blowdown grid used for some time, solid pollutant can stop up grid, needed cleaning, and this just need manually operate, and has increased the cost in the use, and influenced drainage and work normally;
2) traditional grid some be exposed outside, add the accumulation of solid pollutant, so can send niff, contaminate environment;
3) by the sewage behind traditional grid, height of water is bigger before and after it, and stable inadequately, the residual sea water pump that influences the downstream is worked normally.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of novel comminuted grid is provided.
Technology solution of the present utility model is as follows:
Novel breaking type grid comprises body, and the upper surface of described body is fixed with drive unit, and rotary drum, operator group, secondary cutter group are installed in body; Described operator group comprises a main drive shaft that is connected with described drive unit, and main cutting blade is installed on main drive shaft; Described secondary cutter group comprises a counter drive shaft, secondary cutting blade is installed on this counter drive shaft, the follower gear that is fixed on the driving toothed gear on the described main drive shaft and is fixed on the counter drive shaft is meshed, one bottom bracket also is installed in the described body, is fixed with two bearings that match with described main drive shaft, counter drive shaft respectively on the described bottom bracket.
Described novel breaking type grid, described main drive shaft, counter drive shaft are provided with and described two adapter sleeves that bearing matches.
Described novel breaking type grid, described two bearings are self-oiling bearing or rolling bearing.
Described drive unit is made of driving motor, step-down gear, and described step-down gear is fixedlyed connected with adapter sleeve with described main drive shaft.
Described novel breaking type grid, described main drive shaft is made of positive six prisms and a right cylinder, and these positive six prisms are plugged in the main cutting blade, and described driving toothed gear is fixed on the described right cylinder; Described counter drive shaft is made of positive six prisms and a right cylinder, and these positive six prisms are plugged in the secondary cutting blade, and described follower gear is fixed on the right cylinder of described counter drive shaft.
The utility model beneficial effect is:
1) this novel grid adopts the twin shaft design, is installed in two blade staggered arrangement on the axle, realizes screw type cutting, the solid pollutant of fragmenting bulk completely, and also the contaminant particle after pulverizing is even, can not influence the works better of residual sea water pump;
2) this novel grid, partly buried or fully buried installation, noise is little, and the installing space that needs is little, does not need the special messenger on duty, does not also have foul smell to discharge, the environment around can not polluting;
3) by the sewage behind this grid, the height of water of front and back is little, and waterflow stabilization helps residual sea water pump work.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is this novel structural representation;
Fig. 2 is operator group, secondary cutter group, bottom bracket connection diagram;
Fig. 3 is the structural representation of bottom bracket.
Embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees accompanying drawing 1～3; The breaking type grid comprises body 1, and the upper surface of described body is fixed with drive unit 2, and rotary drum 3,4, operator group 5, secondary cutter group 6 are installed in body; Described operator group comprises a main drive shaft 501 that is connected with described drive unit, and main cutting blade 502 is installed on main drive shaft; Described secondary cutter group comprises a counter drive shaft 601, secondary cutting blade 602 is installed on this counter drive shaft, being fixed on driving toothed gear 503 on the described main drive shaft and the follower gear 603 that is fixed on the counter drive shaft is meshed, one bottom bracket 7 also is installed in the described body, is fixed with two bearings 8,9 that match with described main drive shaft, counter drive shaft respectively on the described bottom bracket.
Described main drive shaft, counter drive shaft are provided with the adapter sleeve 10,11 that matches with described two bearings.
Described two bearings are self-oiling bearing or rolling bearing.When rotating speed is lower, can adopt self-oiling bearing, when rotating speed is higher, adopt rolling bearing.
Described drive unit 2 is made of driving motor 201, step-down gear 202, and described step-down gear is fixedlyed connected with adapter sleeve with described main drive shaft.Adapter sleeve one end is connected on the main drive shaft, and the other end is connected on the step-down gear.
