Description

construction waste crusher

technical field

The utility model relates to the field of garbage disposal, in particular to a construction garbage crusher.

Background technique

The main components of construction waste are concrete, bricks, sand, gravel, etc. With the progress of urban construction, construction of new projects, old city renovation and demolition, road reconstruction, etc., will inevitably produce a large amount of construction waste.

A large amount of construction waste is mixed together, and some iron nails or short steel bars are mixed in it. It is very difficult to sort them out, and it will take a long time. Generally, the staff will crush them as construction waste and use them for other purposes. This will not only increase the The difficulty of crushing construction waste also wastes resources and indirectly increases the cost of construction.

At present, the crushing of construction waste is mostly done by manually sorting and classifying metal materials, wood materials and plastic materials, supplying them to the corresponding companies for processing, and then recycling the construction waste after crushing. When entering the crusher, it contains a large amount of fine materials that cannot be used as building aggregates, which easily increases the workload of the crusher, wastes energy, and is prone to dust when crushed, causing environmental pollution.

In order to achieve the above object, the utility model provides the following technical solutions:

A construction waste crusher, comprising a housing, a feed hopper is arranged above the housing, and two crushing rollers are arranged in the housing, and the crushing rollers include crushing teeth, a roller shaft and a drum, and the rollers The shaft is connected with a driving device, the roller is arranged on the outside of the roller shaft, and the crushing teeth are evenly arranged on the outer circumference of the roller; a permanent magnet core is horizontally arranged directly below the crushing roller, and the permanent magnet core is a cylinder body, the central axis of the permanent magnet core passes through the rotating shaft, and the left end of the rotating shaft is fixedly welded with a bevel gear A, and the bevel gear A is meshed with a bevel gear B through the gear, and the bevel gear B is installed on the output shaft of the motor Above, a filter screen is horizontally fixed directly below the permanent magnet core, an oscillator is arranged on the filter screen, and a material taking cover is opened on the housing corresponding to the permanent magnet core; a water spraying cover is provided on the left side of the housing. A water inlet pipe is connected to the water spray pipe, a vibrating screen is arranged on the upper wall of the feeding hopper, and a vibrating feeder is fixedly installed between the vibrating screen and the feeding hopper. There is a curtain at the outlet of the vibrating feeder.

As a further solution of the utility model: a bracket is fixed below the housing, and there are four brackets.

As a further solution of the utility model: there are three water spray pipes.

Compared with the prior art, the beneficial effect of the utility model is that: the utility model is provided with a screening device at the upstream position of the crusher, so that the construction waste can firstly screen and separate the mixed fine materials in the construction waste before the crushing treatment In this way, on the one hand, it can reduce dust flying during crushing, thereby reducing environmental pollution; on the other hand, the screening device can reduce non-renewable aggregates from entering the crusher, thereby reducing the workload of the crusher, saving energy, and prolonging the service life of the crusher. ; The special structure of the crushing roller makes the garbage crushed more evenly, effectively improving the working efficiency of the crusher; the permanent magnet core in the crusher can absorb various iron substances mixed in the construction waste through the drive of the rotating motor, and separate the garbage and iron Separation saves iron resources, reuses some iron materials, and turns waste into treasure. During the crushing of construction waste, a water spray pipe sprays a small amount of water into the shell to reduce dust generated during the crushing process and protect the environment.
