Description
Technical field
The utility model relates to garbage incineration technology field, a kind of water-cooled mucking machine of incinerator specifically, be a kind of lime-ash that incinerator is burnt rapidly cooling and remain intact air-tightness time slag is released to the equipment outside stove, mucking machine operation whether stablize the operation that directly affects incinerator.
Background technology
In incinerator, to be lime-ash that incinerator is burnt release the equipment outside stove by slag to the function of mucking machine after the tank of mucking machine is cooling rapidly.Mucking machine is hydraulic driving mode, owing to having adopted sealing structure for water, therefore has intact air-tightness.Mucking machine is inner has adopted removable abrasion-proof backing block with pusher contact portion.By the ball-cock assembly in mucking machine upper water box, can control the water level of mucking machine.
But the problem below also existing in actual moving process:
1. less (the 0.15m of the volume of water tank
3left and right), sometimes cannot meet moisturizing and deslagging requirement while slagging tap in a large number, simultaneously because lime-ash enters the bottommost that can be deposited on water tank after water tank, water tank there will be often piles up the problem that cannot intake that causes because of lime-ash;
2. because main shaft is in the adverse circumstances of water and slag mixing, and between main shaft and main shaft shaft seal, there is relative motion, must keep certain gap, therefore main shaft shaft seal cannot accomplish to seal completely, the cooling water in tank and lime-ash enter sometimes in main shaft bearing and cause the damage of main shaft bearing; Meanwhile, because the main transmission crank of main shaft adopts single steel plate, make (the about 60mm of thickness) more, when situation is serious, even damage main transmission crank;
3. a lot of companies are used mucking machine for pursuing benefit excess load, make frequently seamlessly operation of mucking machine, and the residue of accumulation has little time to process, and causes larger pressure to little scraper plate, and distortion modification after little scraper plate pressurized, finally comes off; Little scraper plate after coming off enters storehouse after mucking machine, increased the load of slagging tap so that cause get stuck, the phenomenon such as tearing force, simultaneously owing to losing stopping of little scraper plate, part residue enters Hou Cang, causes the parts replacement of mucking machine frequent, the lost of life.
For example, the patent No. is the hydraulic cleanout machine for garbage incinerator fire grate of ZL201120299854.6, although its main shaft bearing adopts external bearing arrangement, what it adopted is rolling bearing, too high to the suitable sensitivity of foreign matter and required precision, in running, easily damage.Therefore, how designing a kind of mucking machine of good stability, is the problem that the application need to solve.
Utility model content
The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, a kind of rational water-cooled mucking machine is provided, this mucking machine should be able to adapt to its inner adverse circumstances, can move continuously for a long time again, can also guarantee the Stability and dependability of operation, and there is simple in structure, easy to use, lower-cost feature simultaneously.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in the figure, the water-cooled mucking machine of incinerator, comprises a mucking machine housing 1 with deep-slotted chip breaker 12, is arranged on mucking machine housing and the water tank 2 supplying water to deep-slotted chip breaker and be arranged in deep-slotted chip breaker and the pusher coordinating with the bottom surface of deep-slotted chip breaker.
In described pusher, main shaft 3 is arranged on the housing of mucking machine by main shaft bearing 13 levels at its two ends, the two ends of main shaft are connected to be driven by it with a hydraulic cylinder 11 being arranged on mucking machine housing respectively, at least two main transmission cranks 4 are installed on main shaft, each main transmission crank is hinged with the rear end of a primary push rod 5 respectively, the front end of each primary push rod be all connected to one coordinate with the bottom surface of deep-slotted chip breaker promote mainly on plate 6, the upside of each primary push rod respectively by hinged seat 8 and a little scraper plate 7 hinged.
Promote mainly and when plate is worked in deep-slotted chip breaker, be divided into 3 states, often when the duty starting when finishing, little scraper plate is relatively good with pusher laminating, and during intermediateness, the drop of little scraper plate is larger, has caused the larger gap that produces between little scraper plate and pusher, makes rubbish enter at any time rear storehouse to little scraper plate build-up of pressure, easily cause little scraper plate to stir, draw and become even distortion, finally cause and come off.Need to improve little scraper plate, the doubling force that makes little scraper plate and pusher is optimum state for this reason, guarantees that little scraper plate pastes firm pusher operation all the time as far as possible, thereby reaches the pressure that reduces little scraper plate, prevents that its distortion from coming off.
As shown in Figure 2,3, in order to prevent that little scraper plate from coming off because of stuck, angle between described little scraper plate and primary push rod is 0-15 degree, and the lower edge of little scraper plate is fixed with a blend stop stretching out 9 downwards, and hinged seat is shaped with at least two-stage for stopping the step 10 of described blend stop towards a side of little scraper plate.When little scraper plate is when pin joint swings, owing to having step to the stopping of blend stop, little scraper plate can not swing excessively when swinging, thereby avoids stuck on primary push rod.
As shown in Fig. 1,2,4, the volume of described water tank is 0.2～0.3m
3, recommend adoption 0.25m
3water tank, overall structure and existing water tank are similar; Difference is in the utility model, the bottom of water tank is 2 inclined-planes in the inclined-plane 2-1(figure of at least one different inclination angle) and a plane 2-2 who is positioned at water tank extreme lower position form, the bottom of this plane is provided with one for discharging the Lou sewage draining exit 2-3 of slag.When having the slag of leakage to enter water tank, under inclined-plane, slide into plane place, the valve that can open sewage draining exit will leak slag discharge.
Each described main transmission crank forms by least two steel plate 4-1 that are arranged side by side, and each steel plate thickness is 25-35mm, and the spacing between steel plate is 20-40mm.The main transmission crank of existing routine adopts single steel plate that 60mm is thick to make conventionally, even may be damaged when leakage slag situation is serious, two blocks of thick steel plates of 30mm of the utility model recommend adoption substitute single steel plate scheme, in the situation that not gaining in weight, promote the intensity of main transmission crank, avoid damaging.
The swing arm that the push rod of described hydraulic cylinder and is arranged on main shaft is hinged, and two hydraulic cylinders of both sides are horizontally disposed.Between main shaft and main transmission crank, by key 3-1, connect, when manufacturing main shaft, keyway processed is driven in unification, the position of two keyways is symmetrical, utilize key to connect this rigidity method of synchronization, drive rushing board mechanism operation (utilizing key and manufacturing process to guarantee the location of push pedal), thereby the location heterogeneity that changes main transmission crank, further guarantees mucking machine workmanship, reaches the object of stable operation.
Described main shaft bearing recommend adoption split plain bearing, bearing shell is selected high temperature resistant, abrasion-proof corrosion-proof corrosion material, increases the service life, and has reduced the workload to the maintenance of bearing.
In figure, also has the water inlet 2-4 of water tank.
