A kind of building waste wood automatic crushing device
Technical field
The invention belongs to production of construction materials technical field, relate to a kind of building waste wood automatic crushing device.
Background technology
In existing production of construction materials technical field, the production of building materials, colliding with when particularly the production of concrete segment is due to moulding, maintenance and carrying easily causes the breakage of building block, this type of building block can not be used further to build by laying bricks or stones, but the words that directly abandon both can be to environment, can cause again the increase of production cost, thereby conventional processing mode is that building block waste wood is broken into powder or granule particle and is re-used as raw material and again processes simultaneously.As flat in Japanese patent gazette No. 6-30755 a kind of renovation process about concrete particle and device thereof are disclosed, it is a kind of to building, civil structure part, the solution body concrete fritter of concrete secondary product etc. carries out fragmentation, the method and apparatus of classification and recycling, it is configured to: the waste wood of having collected is put into and relied on power generation arrangement to carry out in the rotation drum barrel of eccentric rotary, after crushed, the weight of the aggregate dependence that size is suitable itself is fallen to bottom, its powder is put to other in-process again by upside transfer passage, then discharge, and can be segmented by processing procedure again and be separated respectively.It is carried out fragmentation and is separated by rotation drum barrel, and the aggregate of generation is not of uniform size, can not realize automatic screening, and its validity is lower.Meanwhile, waste wood drops that problem also can cause serious environmental pollution with dust, sand-lime fly upward etc. in broken, stacking and transport process.
Summary of the invention
The object of the invention is to have the problems referred to above for existing technology, a kind of building waste wood automatic crushing device has been proposed, it can carry out fragmentation to building waste wood, and can automatically carry out again broken and screening to the larger waste wood of particle, until meet discharging again after broken requirement.
Object of the present invention can realize by following technical proposal: a kind of building waste wood automatic crushing device, it is characterized in that, comprise feed hopper, disintegrating machine, there is the screening frame of blow tank and be arranged on the screen drum on screening frame, described blow tank is inclined at the below of screen drum, the below of described feed hopper is provided with an acclivitous conveyer belt one, the discharge end of described conveyer belt one is positioned at the charging aperture top of disintegrating machine, the discharging opening below of described disintegrating machine is provided with an acclivitous conveyer belt two, described screen drum horizontally set, one end is connected with the discharge end of conveyer belt two, the other end is connected with a downward-sloping charging conduit, the below of described charging conduit is provided with conveyer belt three, the discharge end of described conveyer belt three is positioned at the charging aperture top of disintegrating machine.
In the technical program, waste wood drops on conveyer belt one by feed hopper, then be sent to and in disintegrating machine, carry out fragmentation, waste wood after fragmentation is sent in screen drum and is sieved by conveyer belt two, the satisfactory dust of size or particle screened by screen drum and under leak to blow tank with discharging, the waste wood that particle is larger is dropped on charging conduit by the other end of screen drum, and carry out fragmentation by the triple disintegrating machines that are newly sent to of conveyer belt, waste wood after the fragmentation that repeats and screening until reach after satisfactory size and just discharge from blow tank.
