Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

As shown in the figure, the utility model discloses a waste recovery device for civil engineering, a serial communication port, include: the device comprises a box body 1, wherein a crushing assembly 2, a screening assembly 3, a cleaning assembly 4 and a drying assembly 5 are arranged in the box body 1 from top to bottom;

screening subassembly 3 includes horizontal installation two driving shafts 311, belt and magnet installation area 32 in the box 1, the solid cover has drive wheel 312 on the driving shaft 311, arbitrary end of driving shaft 311 wears out box 1 and outside driving motor 315 drive end fixed connection, two drive wheel 312 passes through magnet installation area 32 transmission is connected, a plurality of magnets are installed to equidistance on the magnet installation area 32, the belt centers on magnet installation area 32 sets up, the internal surface of belt with magnet fixed connection, box 1 inner wall is equipped with metal stripping part 33, metal stripping part 33 sets up 31 below, and be close to arbitrary driving shaft 311 sets up. In the scheme, firstly, waste materials are added into a charging opening, the massive waste materials are cut into waste material particles with uniform particle diameters through the rotary cutting of the crushing assembly 2, the waste material particles fall onto the conveyor belt 31 under the action of gravity, the conveyor belt 31 is driven by the driving motor and is in a moving state all the time, the conveyor belt 31 is internally provided with the magnet group 32, the metal massive materials or the metal particles in the waste material particles can be adsorbed on the conveyor belt 31, when the conveyor belt 31 moves to the tail end, the non-metal particle materials fall into the non-metal particle cleaning cavity 41 under the action of gravity, the metal particle waste materials continue to move by being adsorbed on the conveyor belt 31, when the conveyor belt 31 moves to the position of the stop block 33, the stop block 33 can extrude the metal particle materials adsorbed on the conveyor belt 31 into the metal cleaning cavity 41 due to the tangency of the stop block 33 and the bottom, the conveyor belt 31 continues to circulate above. Because the waste material particle substances fall into the cleaning cavity 41 and fall onto the baffle plates 43 in the cleaning cavity 41, the baffle plates 43 are obliquely and alternately arranged in the cleaning cavity 41, the residence time of the waste material particles in the cleaning cavity 41 is prolonged due to the action of the baffle plates 43, the spray heads 42 spray water on the waste material particles for cleaning, and the waste material particles after cleaning fall into the drying box through the baffle plates 33. The second stopper 33 which is inclined and staggered is also arranged in the drying box, the detention time of waste particles in the drying box is prolonged, the heating assembly 51 is fixedly arranged at the bottom of the box body 1, the fan 52 continuously rotates, heat emitted by the heating assembly 51 is continuously blown into the drying box through the ventilation net by wind, the cleaned waste particles are heated and dried by high-temperature hot wind in the drying box due to the action of the second stopper 33, moisture is evaporated, and finally the waste particles are conveyed to the axis position of the discharge port 6 through the second last stopper 33 and are discharged from the discharge port 6. The purpose is to make the conveyor belt 31 have the ability of adsorbing metal waste, and because the conveyor belt 31 continuously moves, the broken and cut waste particles can uniformly fall on the surface of the conveyor belt 31, and the weakening of the ability of the conveyor belt 31 to adsorb metal particles due to the accumulation of the waste particles can be avoided. Meanwhile, since the conveyor belt 31 moves to the end and changes direction through the driving wheel 312, the metal particles are still adsorbed on the conveyor belt 31 and move synchronously with the conveyor belt 31, and the non-metal particles fall into the cleaning chamber 41 due to the gravity.

In this embodiment, screening subassembly 4 is just right installing wash case 41 in the box 1, two wash cases 41 are close to two driving shafts 311 setting respectively, wash case 41 for the barrel that link up from top to bottom, the shower nozzle 42 is installed to the inner wall of washing case 41, wash and from last to installing baffle 43 down in the case 41 in the crisscross way, baffle 43 downward sloping setting.

In this embodiment, the drying box assembly includes: heating element 51, fan 52, dry chamber 53 and two 54 baffles, dry chamber 53 fixed mounting be in box 1 inner wall and bottom surface are the ventilation net, heating element 51 fixed mounting be in dry chamber 53 bottom, fan 52 fixed mounting be in box 1 bottom central point puts, box 1 bottom both sides are provided with discharge gate 6.

In this embodiment, a feed inlet 7 is fixedly installed at the top of the box body 1, and the feed inlet 7 is funnel-shaped. In this scheme, set up the shape of feed inlet 7 into the funnel form in order to let the waste material get into box 1 more smoothly, and then carry out broken cutting

In this embodiment, the metal stripping element 33 is a horizontal baffle that is tangential to the outer surface of the conveyor belt 31. In the present scheme, since the stop 33 for separating the metal waste particles from the conveyor belt 31 is arranged at the bottom of the conveyor belt 31 at a position tangent to the conveyor belt 31, when the conveyor belt 31 continuously advances, the waste particles on the conveyor belt 31 will be separated from the conveyor belt 31 due to the action of the stop 33 and just fall into the cleaning chamber 41 for cleaning.

In this embodiment, the free end of the second baffle 54 is arranged to be inclined downwards. In this scheme, because two 54 ends of baffle extend to coarse fodder mouth axle center department, the waste material falls into two ends of dog 33 through the crisscross dog 33 two of slope, because piling up of waste material granule, receives the action of gravity, and the whole recovery unit of discharge gate 6 discharge is gone into to the waste material, accomplishes waste material screening and washs and retrieves through discharge gate 6 discharge whole recovery unit.

In this embodiment, the blades 23 are staggered on the surface of the rotating shaft 22. In this scheme, blade 23 staggers in proper order and arranges that the area of contact of blade 23 with the waste material has been increased on pivot 22, can be even break up and cut the waste material, cut into small cubic or graininess with the great waste material of block diameter.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention should be included in the scope of the present invention.
