Efficient crushing device for construction waste

Abstract

The invention discloses a high-efficiency crushing device for construction waste, which comprises a crushing box, a feeding pipe is arranged on the top of the crushing box, a water collecting tray is arranged on the inner wall of the crushing box, and several nozzles are uniformly arranged on the surface of the water collecting tray, and the crushing box There is a water tank on the outer wall on the left side, and a catheter is connected between the water tank and the water collection tray, and a water pump is installed on the catheter; the left and right inner walls of the crushing box are symmetrically equipped with limiting extrusion plates, and the sliding device inside the sleeve There is a sliding shaft, a damping spring is arranged in the sleeve, and the crushing pressure head is in contact with the sawtooth; a control box is provided on the outer wall on the right side of the crushing box, and the control box is electrically connected with the electromagnet plate; The crushing efficiency is high and the crushing effect is sufficient; the buffer plate buffers and absorbs the garbage entering the crushing box, reduces the impact on the crushing roller, improves the stability of the device, reduces mechanical loss and failure rate, and avoids construction The concentrated falling of garbage leads to uneven crushing.

Description

technical field [0001] The invention relates to the technical field of construction waste processing machinery, in particular to a high-efficiency crushing device for construction waste. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, residual mud and other wastes generated during the construction, laying or demolition and repair of various buildings, structures, pipe networks, etc. by construction, construction units or individuals. At present, the amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. Calculated on the basis of 500-600 tons / 10,000 square meters, by 2020, my country will add about 30 billion square meters of new construction area, and the newly generated construction waste will be a shocking number. However, the vast majority of construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is piled in the open ...

Problems solved by technology

However, the vast majority of construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is stacked in the open air or landfilled, which consumes a lot of construction expenses such as land acquisition fees, garbage removal and transportation fees, and at the same time, during the process of clearing, transporting and stacking Problems such as the scattering of dust and flying dust and sand have caused serious environmental pollution.

[0003] However, the structure of the traditional construction waste crushing device is too complex, which has a negative impact on the comprehensive treatment of construction waste to a certain extent, and even forms an obstacle to the further development of the entire industry and the market; the current construction waste crushing device has insufficient crushing effect. The recyclable iron materials in construction waste are not fully recovered, which is likely to cause waste of reusable resources. In addition, in the process of garbage crushing, it is easy to generate a large amount of dust. The diffusion of dust directly affects the air quality of the environment. Can not meet the higher requirements of the modern construction industry
