Description

A kind of building waste grinding device for building
Technical field
The present invention relates to construction equipment field, specifically a kind of building waste grinding device for building.
Background technique
Building waste refers to that construction, all kinds of buildings of unit in charge of construction or personal team, structures, pipe network etc. are built, spread If or remove, in reparative processes produced by dregs, spoir, rejected material, remaining mud and other wastes.Currently, China's building waste Quantity accounted for the 30%-40% of municipal refuse total amount.It is calculated with 500-600 tons/ten thousand square metres of standard, arrives the year two thousand twenty, Also by about 30,000,000,000 square metres of newly-increased construction area, newly generated building waste will be a shocking number in China.So And most building wastes just transport countryside or rural area, air storage or landfill to by unit in charge of construction without any processing, consumption With pork barrels such as a large amount of land acquisition expense, refuse collection expenses, meanwhile, it clears and dropping and dust, ash in stacking process The problems such as sand is flown upward causes serious environmental pollution again.
Processing mode more environmentally friendly at present but due to material damage, is built to building waste recycling and reusing Building material and can carrying out the part of high-volume recycling is mainly stone material, brick etc., as Concrete Filled after be crushed It uses, but it is bad to the crushing effect of the bulks building waste such as stone material, brick, and the recycling rubbish partial size of acquisition is larger, reduces Its subsequent utility value.
Chinese patent notification number CN108686799A proposes a kind of building waste apparatus for crushing and treating, with existing processing Device is mostly similar, carries out extruding pulverization process to building waste, but there is problem in actual use, such as with existing device It is similar, it only exists magnet Attraction structure and metal component present in building waste is recycled, but at present for metal component Screening, it is most of to be all purged by lifting electromagnet, but the ingredient that other in building waste mix is especially large quantities of The wood materials and plastic material of amount are difficult to carry out screening process, influence efficiency if artificial screening, but without screening out Negative impact can be generated to smashed quality of materials.
Summary of the invention
The purpose of the present invention is to provide a kind of building waste grinding devices for building, to solve to build bulk for building Rubbish crushing effect is bad, the larger problem of recycling rubbish partial size.
To achieve the above object, the invention provides the following technical scheme:
A kind of building waste grinding device for building, including crush box, the crush box is equipped with to be entered for building waste Garbage inlet and the garbage reclamation outlet that is discharged after being crushed for building waste, garbage pulverator is equipped in the crush box Structure;It is characterized in that, the crush box includes roughing case and fining-off case, the fining-off case is located at below roughing case, And fining-off case is connected to setting with roughing case;
The garbage pulverator structure includes level-one garbage pulverator structure and second level garbage pulverator structure;The level-one rubbish powder Broken mechanism is set in roughing case, is made of multiple shredding rolls that horizontal Tile is arranged, blade, institute are placed on the shredding roll It states shredding roll and is separately fixed on different line shafts and connect with motor drive;The second level garbage pulverator structure is set to fining-off It in case, is constituted by the cavity of open top and set on the intracorporal pulverization cylinder of the chamber, the open end of the cavity and roughing case Connection, the pulverization cylinder are connect by drive shaft with motor drive;The cavity bottom is equipped with to be gone out as what garbage reclamation exported Cinder notch.
A kind of embodiment of the invention, the cavity are cylindrical cavity, and the pulverization cylinder and the cavity are coaxially disposed; The fining-off case inner bottom surface is fixed with first motor, and the first motor is located at immediately below the cylindrical cavity, the first electricity The output shaft of machine is fixedly connected with the drive shaft.
Further, the lower half of the pulverization cylinder is cylindrical, and the upper half is round table-like in closing up upwards.By this Setting, building waste are fallen to after level-one crushes at the top of pulverization cylinder, due to the rotation of pulverization cylinder, subsequently into pulverization cylinder with Gap between cavity carries out second level crushing, is more advantageous to using up big and down small gap and is rolled to building waste, crushes effect Fruit is more preferable.
The present invention can be further improved, and the cylindrical cavity bottom is equipped with sealing station.Sealing station can prevent from crushing Building waste blocking block drive shaft, cause Caton to stop working.
Further, cylindrical cavity open end top is equipped with struggles against in funnel shaped aggregation, opens on the aggregation bucket Mouth end is connect with roughing bottom portion, and the lower open end of the aggregation bucket is connect with the open end at the top of the cavity.
A kind of embodiment of the invention, there are two the shredding rolls, and the roughing box outer wall is fixed with the second motor, The output shaft of the motor by transmission chain and a connecting shaft transmission connection, and the output shaft and connecting shaft respectively with two institutes The line shaft for stating shredding roll is connected.
Of the invention can do following improvement, be equipped with side clamping plate on the inner wall of roughing case two sides, side clamping plate has The identical independent plate of multiple spacing, and independent plate with and its shredding roll for being disposed adjacent on occlusion blade stagger be arranged.
The present invention can also do following improvement, and the building waste grinding device for building further includes screening case, the sieve Branch mailbox is the cabinet of open top, and inner inclination is equipped with input tape;One end of the input tape is set to screening box body Bottom, the other end are set to outside screening box body and are located above the crush box garbage inlet;It is additionally provided in the screening case Isolation board, the isolation board are located above the conveyer belt.
Further, the isolation board is set in the middle part of the screening case side wall, and is obliquely installed.
Further, magnet plate is fixed on the isolation board.
As a further improvement of the present invention, there are also sloping platform, the sloping platform is set in screening case close to defeated the screening case Enter the side with bottom end, inclined-plane face input tape, sloping platform inclined-plane lower part is additionally provided with guide plate so that guide plate lower end with Belt surface docking is inputted, reaches input tape for building waste to be oriented to.
Further, the screening bottom portion is set there are four supporting leg, and each supporting leg bottom is equipped with lifting idler wheel.
