Problems solved by technology

[0003] During the use of the existing crushing and screening device, the volume of the crushing chamber is fixed, which cannot be changed according to the amount of construction waste, which leads to a larger crushing chamber when the amount of waste is small, and a greater mutual extrusion force between the wastes. Small, the distribution of waste is

Example Embodiment

[0039] Example 1:

[0040] see figure 1 , a pulverizing and screening device for recycling construction waste, comprising a pulverizing shell 1, a controller (not shown) is arranged on the pulverizing shell 1, and there are two in the pulverizing shell 1 by which are arranged outside the pulverizing shell 1 The driving motor drives and rotates the crushing roller 6 with crushing teeth (the driving motor is not shown, the driving motor is electrically connected to the controller), the rotation directions of the two crushing rollers 6 are opposite, and the crushing teeth on the two crushing rollers 6 The two crushing rollers 6 are engaged with each other, so that the crushing efficiency of the two crushing rollers 6 is higher. The upper end and the left end of the crushing shell 1 are respectively provided with a feeding port and a discharging port, and an inclined setting is fixed between the left and right inner walls of the crushing shell 1. The sieve plate 7 is located on t...

Abstract

The invention discloses a pulverizing and screening device for building waste recycling, and belongs to the technical field of building waste treatment. The pulverizing and screening device for building waste recycling comprises a pulverizing shell, and the pulverizing shell is internally provided with pulverizing rollers with pulverizing teeth, wherein the pulverizing rollers are driven by a drive motor arranged at the outer portion of the pulverizing shell to rotate. The upper end and the left end of the pulverizing shell are provided with a feeding port and a discharging port correspondingly. Through the arrangement of a position control piece, the size of a pulverizing cavity formed between the position control piece and the pulverizing shell can be controlled according to the waste amount, accordingly, waste distribution is centralized, and the pulverizing efficiency is improved. Meanwhile, when the pulverizing process reaches a certain stage, waste intercepted by a screening plate can be guided into a material receiving bag, the waste in the material receiving bag is poured into the pulverizing shell through a charging pipe again, the poured waste in the state can be centralized between the two pulverizing rollers in advance, and the pulverizing efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, and more particularly to a crushing and screening device for construction waste recycling. Background technique [0002] With the progress of society and the development of science and technology, there are more and more buildings, and at the same time, in the process of construction, there are more and more construction wastes. Construction waste refers to the muck, spoil, waste material, residual mud and other wastes generated during the construction of various buildings; these construction wastes are of no help to the building itself, but are used in construction Therefore, it is necessary to carry out corresponding treatment in order to achieve the ideal project construction. Some construction wastes are large in size and need to be pulverized before transportation to pulverize the construction wastes into small particles. Thus, it can be easily transported and stored. ...
