Embodiment 1

[0054] Please refer to figure 1 This embodiment provides an extrusion equipment 100 for civil engineering, which is mainly used to squeeze and crush massive construction waste (such as hollow bricks) into granules for reuse. The above-mentioned squeezing device 120 mainly includes a pushing plate, a fixed plate and a hydraulic system. The construction waste is thrown between the pushing plate and the fixed plate, and the hydraulic system drives the pushing plate to squeeze the construction waste.

[0055] Please continue to refer figure 1 And reference figure 2 , The extrusion equipment 120 mainly includes a frame 121, a fixed plate 131, a push plate 132, a bottom plate 133 and a hydraulic system. The frame 121 is used to fix and connect the remaining components, the push plate 132, the fixed plate 131 and the bottom plate 133 are used to form a pressing space, and the hydraulic system is used to provide power to the push plate 132.

[0056] The fixing plate 131 is vertically arra...

Embodiment 2

[0076] This embodiment provides a construction waste treatment system for civil engineering, including a screening device and the extrusion device for civil engineering in Example 1, where the screening device is arranged below the extrusion device; the screen Sub-equipment includes vibrating screen.

[0077] The screening equipment further includes a vibration motor for driving the vibration screen to vibrate. After screening, the particle size of the construction waste at the bottom of the vibrating screen is relatively small and can be directly used to make hollow bricks, etc.; the size of the construction waste on the vibrating screen is still relatively large and cannot be used directly, and it is collected and re-invested in the pressurized equipment. extrusion.

Embodiment 3

[0079] This embodiment provides a construction waste treatment method for civil engineering, which adopts the treatment system 100 in Embodiment 1, and includes the following steps:

[0080] a. Crushing; the block-shaped construction waste is initially crushed with a breaking hammer, etc.;

[0081] b. Squeeze; After the construction waste falling from the crushing device 110 falls into a pile in the crushing device 120, turn off the crushing device 110 and start the hydraulic system of the crushing device 120; push the plate 132 toward the direction of the fixed plate 131 and move Squeeze the construction waste toward the fixed plate 131, and the pressure sensor 138 transmits the pressure signal of the push plate 132 to the controller;

[0082] c. Adjust the three-position four-way proportional valve 127; when the pressure value gradually increases, the controller energizes the three-position four-way proportional valve 127 to make the spool act, and the proportional valve supplies o...

Abstract

The invention provides energy-saving extrusion equipment for civil engineering, a construction waste treatment system and a method, and belongs to the field of civil engineering construction. The extrusion equipment is mainly used to pulverize construction waste (such as hollow brick bricks) into granulation for reusing and mainly comprises a push plate, a fixing plate and a hydraulic system; theconstruction waste is poured between the push plate and the fixing plate; and the hydraulic system drives the push plate to extrude the construction waste. When in use, the broken construction waste is put into the extrusion equipment, the hydraulic system is activated, and the push plate extrudes the construction waste to further crush it; most of the construction waste treated by breaking equipment and the extrusion equipment has a small particle size and is then sieved; and the construction waste in the lower portion of a vibrating screen is small in size and can be reused. The equipment, system and method are effective in saving construction materials, and moreover, the entire system has higher energy utilization and saves energy.

Description

Technical field [0001] The invention relates to the field of civil engineering, in particular, to an energy-saving construction waste treatment system and method of extrusion equipment for civil engineering. Background technique [0002] Construction waste may be generated during civil engineering construction. For example, when a building is blasted, more hollow bricks are often generated. The direct discarding or burying of these garbage will occupy a lot of land resources. If the above-mentioned construction waste can be reused, this will not only save a lot of land resources, but also turn waste into treasure and save other construction materials. However, block construction waste is difficult to be used directly; it needs to be crushed before being used; in order to re-make hollow bricks or other building materials. Summary of the invention [0003] The purpose of the present invention is to provide an extrusion device, which can effectively pulverize block construction was...
