firstly, the building garbage can be conveniently and quickly separated in an energy-saving and environment-friendly manner, and the reinforcing steel bars can be primarily separated from materials with specific gravity greater than that of water and materials with specific gravity less than that of water, such as wood and cement concrete. And the noise is low, and the damage of broken noise to the hearing of users and surrounding environment personnel can be reduced.
Second, crushing in-process can produce huge noise, and the noise abatement that the puigging can be fine to protection constructor's hearing. Because construction waste includes reinforcing bar, timber, cement concrete, and construction waste after above-mentioned quartering hammer is smashed includes above-mentioned three kinds of blendings, and wherein the reinforcing bar can not smashed, only can warp, and timber and cement concrete then can form the broken block shape, and the compounding that three kinds of materials formed falls down by oneself because of the action of gravity from the compounding export to in the reinforcing bar separating element of below falls. The self-falling has the energy-saving effect, and no additional conveying power is needed.
And thirdly, after the mixed material falls on the screen, starting a second vibrating motor to drive the screen to vibrate, and because the wood and the cement concrete are crushed into fragments, the fragments can fall into a water tank below through the screen, and the reinforcing steel bars are still positioned above the screen, so that the reinforcing steel bars can be separated out for recycling. The screen cloth can set up to the slope form to be favorable to the reinforcing bar to follow the same one side of unified flow direction screen cloth, conveniently collect the reinforcing bar. Along the long part, pieces of wood and cement concrete can be prevented from falling outside the water tank.
And fourthly, the pause cavity is used for storing the water filtered by the filtering layer after the wood and the cement concrete are separated so as to be used next time, and the water can be reversely pumped into the cavity at the top of the partition board through the first water pipe and the water pump when being used next time. After timber and cement concrete separation, open the valve on the second water pipe, because no water in the temporary storage chamber, because atmospheric pressure's effect, water can be automatic from water storage chamber to temporary storage chamber, until the surface of water is located same water flat line, also adopt natural force here to carry out the water guide effect to the water flat line of baffle top cavity falls to being less than the filter layer top at least, this can be realized through the volume proportion of design temporary storage chamber, holding water cavity, baffle top cavity, specifically designs according to the needs of use.
