Description
Technical Field
The invention relates to the technical field of building material treatment, in particular to a waste brick treatment device.
Background
The waste brick is one of the main components of the construction waste, and the recycling degree and the recycling way of the waste brick directly influence the recycling and industrialization process of the construction waste. The resource utilization of the waste bricks has important significance for developing circular economy and protecting environment.
The waste bricks are formed by pushing the whole building outer shell, then properly smashing and scattering the brick wall by using a movable stone crusher, and then manually removing mortar on the bricks. The waste bricks are damaged more or less in the process of building demolition, and the waste bricks are not suitable for direct secondary use any more after being used for a period of time, so the waste bricks need to be recycled. The existing treatment of waste bricks is generally to crush the waste bricks, then to be processed into particles or powder after manual screening, and to be used as road surface and roadbed materials, or to be processed into other building products such as recycled concrete and the like. The waste bricks are required to be crushed, then manually screened and finally ground into powder in the treatment process, the treatment method not only requires manual cooperation during treatment, but also requires a plurality of devices, so that the treatment steps of the waste bricks are complicated, and manpower and material resources are wasted. Therefore, a convenient and fast waste brick processing device is needed.
Disclosure of Invention
The invention aims to provide a waste brick treatment device to solve the problems of complicated steps and waste of manpower and material resources in the conventional waste brick treatment.
In order to solve the technical problems, the invention provides the following technical scheme: a waste brick treatment device comprises a box body and a grinding mechanism, wherein a feed inlet is formed in the top of the box body, a pair roller is rotatably connected to the inner wall of the box body and located below a discharge outlet, a motor used for driving the pair roller to rotate is fixedly connected to the box body, a guide plate which inclines downwards is fixedly connected to the inner wall of the box body and located below the pair roller;
milling mechanism includes the otter board of first grinding roller, second grinding roller and downward sloping, otter board fixed connection is on the inner wall of box, and the otter board is located the below of deflector lower extreme, first grinding roller with the second grinding roller all rotates with the box inner wall to be connected and is located the otter board top, and interval 1 ~ 3cm between first grinding roller and the otter board, second grinding roller and otter board clearance fit, first grinding roller and second grinding roller with the motor passes through belt transmission, the bottom half is equipped with the discharge gate, and the discharge gate is located the otter board below.
The working principle of the invention is as follows: the utility model discloses a pair roller of roller pair, including the otter board, the otter board is connected with the guide plate, the roller pair is connected with the guide plate, the motor drives the roller pair rotation during the motor operation, the motor passes through the belt simultaneously and drives first grinding roller and second grinding roller and rotate towards the otter board direction, put into the pair roller through the feed inlet with useless brick this moment on, extrude the breakage to useless brick when the roller pair rotates, after the useless brick is broken for the fragment, because the deflector downward sloping, and the lower end of deflector is located the top of otter board, so the fragment can drop on the deflector under the action of gravity. Because the surface of first grinding roller and second grinding roller is dull polish form, and the otter board also downward sloping sets up, the interval between first grinding roller and the otter board is 1 ~ 3cm simultaneously, second grinding roller and otter board clearance fit, so the fragment can block between otter board and first grinding roller when sliding to first grinding roller department under the action of gravity, grind the fragment into powder towards the otter board when first grinding roller rotates at a high speed, when the fragment is ground the diameter and is less than 1 ~ 3cm, the fragment slides to second grinding roller department along the otter board at the action of gravity line, when second grinding roller and fragment contact, because second grinding roller and otter board clearance fit, so the fragment is ground into powder completely when the second grinding roller rotates. And the fragments become powder, then fall from the gap of the screen plate to the discharge port below, and fall out of the box body through the discharge port.
The invention has the beneficial effects that: 1. this scheme is earlier through the pair roller to the brick of wasting discharge and carries out the extrusion breakage, makes the great brick of wasting discharge become the fragment of fritter of bulk, then polishes the fragment that the diameter is greater than 1 ~ 3cm through first grinding roller, and the fragment that the diameter is less than 1 ~ 3cm then slides to second grinding roller department through the clearance between first grinding roller and the otter board, makes the great fragment of bulk and the less fragment of volume can separately grind in step, the effectual treatment effeciency to the brick of wasting discharge that has improved. 2. Directly putting into waste brick processing apparatus with waste brick during this scheme uses can directly polish into the powder with waste brick, reduced manual operation's step, do not need many equipment to cooperate the use simultaneously, consequently not only reduced the manual work, but also reduced the use quantity of equipment.
Further, the top fixedly connected with hopper of box, hopper and feed inlet intercommunication. Its purpose can put into a large amount of waste bricks in the hopper through this kind of setting, makes it fall the pair roller through gravity is automatic on, reduces the number of times that adds waste bricks.
Further, the lower surface of otter board fixedly connected with sucking disc leaves the cavity between sucking disc and the otter board, the box is equipped with the aspiration pump outward, and the air inlet intercommunication of aspiration pump has the trachea, and the trachea passes box and sucking disc and cavity intercommunication in proper order. The purpose is that the mass of the powder is small, the powder is inevitably adsorbed on the screen plate due to static electricity and the like to cause the screen plate to be blocked, and therefore the powder on the screen plate is absorbed away by the suction force generated by the air suction pump.
Furthermore, a plurality of hemispherical lugs are uniformly distributed on the pair roller. The roller pair type waste brick crusher has the advantages that the contact surface of a waste brick and a roller pair is reduced through the hemispherical convex blocks, force applied to the waste brick by the roller pair is increased, and the roller pair type waste brick crusher has a better crushing effect.
Further, first grinding roller and two grinding rollers in ground can dismantle with the box and be connected, one side of box is uncovered, it has the chamber door to articulate on the uncovered. The purpose is that the first grinding roller and the second grinding roller inevitably become smooth after being used for a long time, so that the grinding effect is poor, and therefore the first grinding roller and the second grinding roller can be replaced conveniently through the arrangement.
