Description

A kind of civil engineering construction waste treatment equipment

technical field

The invention relates to the technical field of waste treatment equipment, in particular to a civil engineering construction waste treatment equipment.

Background technique

Concrete is the most important material in civil engineering. With the increasing scale of civil engineering construction, the reinforced concrete structure has become the main body of the building structure, which makes the production of ready-made concrete develop rapidly. Civil engineering will produce a large amount of concrete waste, which is large in size and difficult to degrade. The traditional landfill treatment method is not enough to deal with it, so concrete waste treatment equipment has appeared. Existing concrete waste treatment devices usually use the combination of crushing rollers and extrusion rollers to crush construction waste. Generally, regardless of the size of the waste, it is directly thrown into the treatment equipment. However, when encountering large pieces of waste, it is easy to cause the treatment equipment to be stuck and must be shut down for cleaning. , waste a lot of time and manpower, and affect the service life of the processing equipment; or manually smash large pieces of waste into small pieces and then put them into the processing equipment, which greatly reduces the processing speed and efficiency, and the high labor cost seriously affects the benefits of the enterprise.

As an improvement of the above technical solution, the power device includes a second motor, an eccentric wheel is connected to the output shaft of the second motor, a connecting rod is arranged on the eccentric wheel, and the upper end of the extrusion plate is hinged on the A connecting rod, the lower end of the extruding plate is connected with a supporting rod, and the other end of the supporting rod is hinged to the inner wall of the crushing box.

As a further improvement of the above technical solution, the crushing roller and the squeezing roller are provided with a crushing pattern on the roller surfaces.

As a further improvement, four outriggers are provided on the bottom surface of the crushing box, and casters are connected to the lower ends of the outriggers.

As a further improvement, a feed hopper is connected to the feed inlet, and the feed hopper is in the shape of an inverted cone.

As a further improvement, the feed hopper is set as a metal part and welded to the upper end surface of the crushing box.

The beneficial effects of the present invention are: construction waste enters the crushing box and first passes through the crushing device and falls into the V-shaped passage between the fixed plate and the extrusion plate, the power device drives the extrusion plate to move towards the fixed plate, and the extrusion plate and the fixed plate The construction waste is crushed into small pieces first, and then the small pieces fall between the crushing roller and the squeezing roller. The crushing roller rotates under the drive of the first motor, and the small pieces of construction waste are crushed into powder by cooperating with the squeezing roller. Finally, the powder is discharged from the discharge port; the large pieces of construction waste are first crushed into small pieces by the crushing device, which avoids the blockage of the crushing roller caused by the large pieces of construction waste, improves operating efficiency, reduces downtime, and saves a lot of manpower ,Time costs.

Detailed ways

Referring to Figures 1 to 3, a civil engineering construction waste processing equipment includes a crushing box 1, the upper end surface of the crushing box 1 is provided with a feed port 11, and a feed hopper 9 is connected to the feed port 11. The feed hopper 9 is in an inverted cone shape, and the feed hopper 9 is welded by metal plates, and is welded on the upper surface of the crushing box 1, which is reliable and durable; A supporting leg 13 is used to form a space for the crushed construction waste to fall and provide a stacking space. The lower end of the supporting leg 13 is connected with a caster 8, which is convenient for moving the processing equipment. The caster 8 has a built-in brake structure, and the processing equipment can be fixed at any position; The inside of the crushing box 1 is provided with a relatively arranged crushing roller 3 and a squeeze roller 4 at a position close to the discharge port 12, and the roller surfaces of the crushing roller 3 and the squeeze roller 4 are provided with a crushing texture, which increases the amount of crushed construction waste.
