Abstract
The invention discloses a concrete aggregate regeneration apparatus used for construction waste and construction waste residue treatment. The apparatus comprises a frame (1), a feeding hopper (2), crushing rollers (11), stripping rollers (12), a swing plate (9) and auxiliary facilities, and the swing plate (9), the crushing rollers (11) and the stripping rollers (12) are installed in the frame (1). The concrete aggregate regeneration apparatus is characterized in that the upper portion in the frame (1) is designed to be a crushing section, the lower portion in the frame (1) is designed to be a concrete (13) stripping section, the swing plate (9) is arranged over the crushing rollers (11), and a concrete aggregate separation section comprises two stripping rollers (12) having a same rotation direction. Regenerated concrete aggregates obtained in the invention are not physically damaged, have a complete structure, and are not different from new aggregates, so the apparatus multiplies the construction waste and construction waste residue reutilization rate, and has a far lower cost than aggregate heating reduction methods, thereby the added values of construction waste and construction waste residue recycling reduction are greatly improved, and circulative utilization is truly realized.
Description
Technical field
The present invention relates to the treatment unit of a kind of building waste and building waste residue, relate to it is carried out to the recycling of aggregate regeneration reducing.
Background technology
The main component of building waste, building waste residue is concrete, fragment of brick, sandstone and dregs etc.; in the process such as urban construction, reconstruction of the old city town; can produce a large amount of building waste and building waste residue; its quantity has accounted for the 30%-40% of municipal wastes total amount; cumulative amount is astronomical figure especially, can finely address this problem the great people's livelihood problems in each city, various countries such as being related to cultivated land protection, environment protection, life quality, energy-saving and emission-reduction.
At present all kinds of comprehensive treating process schemes about building waste and building waste residue emerge in an endless stream, but make full use of and maximizing the benefits aspect all exist deficiency, added value is on the low side, all can not really accomplish repetition, cycling and reutilization.Aspect the comprehensive treating process of building waste and building waste residue, foreign study early, as the good heat reduction aggregate method that has the states such as Japan of doing, domestic research is evening relatively, its processing mode of domestic enterprise is mainly simple crushing, and piece material is paved the way, the low value-added mode of fines brickmaking, is not high cost, be exactly that added value is on the low side, have a strong impact on industry development.Also have many enterprises to attempt to carry out aggregate reducing/regenerating, because of its broken means deficiency, the physical strength of aggregate is damaged eventually, and prefabricated components do not reach design strength and require and come to an end.
Summary of the invention
The present invention relates to the aggregate regenerating unit of a kind of building waste and building waste residue, it is different from Hubei Province formula fragmentation or reaction type fragmentation causes physical damnification to aggregate, has reduced aggregate intensity.The present invention utilizes building waste different from the hardness of cement with aggregate in building waste residue, the phenomenon that can separate with cement with aggregate in exploitation process at static pressure, be as good as by the aggregate and the virgin material that facts have proved such regeneration, and can not cause physical damnification to aggregate, the utilization ratio of building waste and building waste residue can be significantly improved, its reduction cost is far below heat reduction aggregate method, thereby the added value of building waste and building waste residue regeneration reducing is significantly promoted, really accomplished recycling utilization.
The aggregate regenerating unit of stating; in frame, above a pair of breaker roll, be designed with a pendulum plate; when the concrete strength attacking and destroy when a side pressure roller exceedes design; pendulum plate can tilt to push opposite side concrete along swing plate shaft; both played the dual function of protection pressure roller and power system; again can be to opposite side concrete transferring energy; can play like this pressure spring or the same purpose of cylinder pressure system of traditional rolling disintegrator; not only simply easily realize, and low cost, without consumable accessory.
The aggregate regenerating unit of stating, in frame, below a pair of breaker roll, be designed with a pair of stripper roll, this to stripper roll turning direction in the same way, when entering stripper roll, concrete blocks can rotate, due to the aggregate in concrete blocks and cement hardness different, in the time of rotary squeezing, aggregate is convenient to cement and is separated like this, because the adjustment of roll gap can be greater than aggregate diameter, now aggregate is separated by complete, reaches aggregate regeneration object.
The aggregate regenerating unit of stating is divided into reduction stage and the section of peeling off in frame.

Embodiment
As Fig. 1, shown in Fig. 2, a kind of aggregate regenerating unit for building waste and building waste residue processing, comprise frame (1), hopper (2), breaker roll (11), stripper roll (12), pendulum plate (9) and off-set facility, the axle (10) of pendulum plate (9), the axle (5) of a pair of breaker roll (11), the axle (6) of a pair of stripper roll (12) is fixed in frame (1) by bearing respectively, a pair of breaker roll (11) is installed respectively two belt pulleys (3) on axle (5), be connected with electric motor (7) by belt (14), the axle (6) of a pair of stripper roll (12) is installed belt pulley (4), be connected with electric motor (8) by belt (14), so just, in frame (1), having formed epimere is crushing function, hypomere is the aggregate regenerating unit of peeling off function.
As shown in Figure 3, Figure 4; the sense of rotation of two breaker rolls (11) is contrary; in the time that concrete blocks (13) enters pendulum plate (9) two side; concrete blocks (13) can not be identical in shape, size, stress point and the stressed size of pendulum plate (9) two sides; stressed large or while exceeding the moment capacity of breaker roll (11); concrete blocks can push pendulum plate (9) and be offset to opposite side; so not only can strengthen the space of passing through of concrete blocks (13), also effectively protect breaker roll (11) and power set.The sense of rotation of two stripper roll (12) is identical.
Aggregate regenerating unit of the present invention, the thickness of pendulum plate (9) can be set arbitrarily, so just, can effectively adjust breaker roll (11) roll gap, this roll gap adjustment mode is obviously simpler than mobile crushing roller (11) and adjusts roll gap.
Aggregate regenerating unit of the present invention; pendulum plate (9) interacts by the material of two sides; play the material broken effect of pressurizeing; save and use complex appts, by breaker roll (11), material is carried out to pressuring method; when material hardness or institute's energy requirement exceed the holding capacity of breaker roll (11); the energy that can discharge material by the skew of pendulum plate (9), self-adaptation material plays the protection to breaker roll (11) and power set by space.
Aggregate regenerating unit of the present invention, the sense of rotation of two stripper roll (12) in the same way, concrete blocks (13) can be rotated extruding during by stripper roll (12), different along with aggregate and cement hardness, and aggregate can separate with cement.
The above, be only preferred forms of the present invention, and the restriction of not the present invention being done according to content disclosed in this invention, the simple change of carrying out, equivalent structure transformation, substitutes or identical, all should belong to the protection domain of technical solution of the present invention.
